Heating cooker

0001The present invention relates to a drawer-type cooking cooker having a microwave oven function.

0002Conventionally, a drawer type cooking cooker has been proposed (see Patent Documents 1 to 4). The pull-out type heating cooker includes a cooker main body having a heating chamber, an electromagnetic wave generating unit, and a waveguide for guiding the electromagnetic wave generated by the electromagnetic wave generating unit to the inside of the heating chamber. The electromagnetic wave generating portion is arranged behind the heating chamber, and the waveguide is provided from the electromagnetic wave generating portion to the upper part of the heating chamber.

0003Further, the drawer-type heating cooker includes a storage body for storing the object to be cooked. The storage body can appear and disappear inside the heating chamber by two slide rails on both sides arranged on the left and right sides of the heating chamber and one lower slide rail arranged below the heating chamber. It is supported. Rack gears are attached to the lower slide rails. When the motor rotates and drives the pinion gear that meshes with the rack gear, the housing body is pulled out from the inside of the heating chamber or pushed into the inside of the heating chamber (that is, appears and disappears). The motor and pinion gear are located below the bottom wall of the heating chamber.

0004By the way, a general cooking cooker that is not a drawer type may be provided with a movable heater (see Patent Documents 5 and 6). The movable heater is driven by a motor to swing automatically, or the user manually swings it. The movable heater appropriately heats the object to be cooked by moving it into contact with the object to be cooked or orbiting along the surface of the object to be cooked.

For this purpose, the heating cooker is configured to transfer heat from the heater arranged on the top wall side inside the heating chamber to the side to be cooked located below the heater.</p><p num="0007"> In this case, the heat generated by the heater is also transferred to the upper and lower parts of the heating chamber. Therefore, the lower slide rail, the rack gear, the pinion gear, and the motor arranged below the heating chamber tend to become hot. However, rack gears, pinion gears, and motors generally have low heat resistance. However, if all of these are made highly heat resistant, the manufacturing cost of the cooking cooker will increase.</p><p num="0008"> The present invention has been made in view of such circumstances, and a main object thereof is to provide a drawer-type cooking cooker which is a multifunctional type including a microwave oven function and can be manufactured at low cost.</p>

The electromagnetic wave generating unit and the waveguide include a heater arranged on the top wall side or the bottom wall side inside the heating chamber in a heating cooker arranged outside the heating chamber, and the actuator. Is arranged in a low temperature region other than the high temperature region facing either the top wall or the bottom wall of the heating chamber.</p><p num="0010"> In the heating cooker according to the present invention, the heater is arranged on the top wall side inside the heating chamber, and the electromagnetic wave generating portion is arranged in the low temperature region facing the rear wall or the side wall of the heating chamber. The waveguide is characterized in that it is arranged in the low temperature region facing the rear wall or side wall of the heating chamber, or in the high temperature region facing the bottom wall.</p><p num="0011"> In the heating cooker according to the present invention, the heater is swingably supported between the top wall side inside the heating chamber and the storage position side of the object to be cooked, which is lower than the top wall side. The heater is provided with a swing mechanism that swings the heater toward the top wall side / the storage position side in conjunction with the opening / closing of the storage body.</p><p num="0012"> In the heating cooker according to the present invention, the housing body integrally has a door for opening and closing the opening, and the swing mechanism has a swinging portion that swings together with the heater and the heater. The urging portion in which the heater swings toward the top wall side and the swinging portion are separated / approached as the accommodating body moves in / out, and the shaking occurs when the door closes. It is characterized by having a contact / detachment portion for applying an external force to the swinging portion in a direction in which the heater swings toward the storage position side in contact with the moving portion.</p><p num="0013"> In the heating cooker according to the present invention, the heater is arranged on the top wall side inside the heating chamber, and the movable antenna that scatters the electromagnetic wave guided by the waveguide into the inside of the heating chamber and the said The movable antenna, the drive unit, and the blower unit are provided with a drive unit for driving the movable antenna, a blower unit, and a ventilation path for guiding the air blown by the blower unit to each side of the electromagnetic wave generation unit and the drive unit. The ventilation passage is arranged in the low temperature region facing the rear wall or side wall of the heating chamber outside the heating chamber.</p><p num="0014"> The heating cooker according to the present invention has a slide rail that supports the storage body so as to be able to appear and disappear, a rack gear that is attached to the slide rail and that appears and disappears together with the storage body, and a pinion gear that meshes with the rack gear. Further provided in the low temperature region facing the side wall of the heating chamber outside the heating chamber, the actuator is a motor for rotationally driving the pinion gear, and is arranged in the low temperature region facing the side wall. It is a feature.</p>

<p num="0015"> In the case of the heating cooker of the present invention, the actuator for infesting the storage body is arranged in a low temperature region where the heat generated by the heater is difficult to transfer. Therefore, as an actuator to be provided in the cooking cooker, an inexpensive actuator having the same low heat resistance as the conventional one can be adopted. As a result, a multifunctional drawer-type cooking cooker including a microwave oven function can be manufactured at low cost.</p>

0017Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments thereof. In the following description, the up and down, front and back, and left and right indicated by arrows in the figure are used.

0018Embodiment 1. FIG. 1 is a perspective view illustrating the external configuration of the cooking cooker 1 according to the first embodiment of the present invention. 2 and 3 are a plan view and a side view schematically showing the internal configuration of the cooking cooker 1. The cooker 1 constitutes a part of the system kitchen. The cooker 1 includes a cooker main body 2, a storage body 3, slide rails 41 to 43, a rack gear 44, a pinion gear 45, a motor 46, a magnetron 51, a waveguide 52, and a heater 53.

0019The cooker main body 2 has a rectangular parallelepiped housing 21 and a horizontal bottomed rectangular tubular heating chamber 22 formed inside the housing 21. The housing 21 integrally has each rectangular front wall 21a, rear wall 21b, left side wall 21c, right side wall 21d, top wall 21e, and bottom wall 21f made of metal. The heating chamber 22 has a rectangular opening 22a, and integrally has a metal rear wall 22b, a left side wall 22c, a right side wall 22d, a top wall 22e, and a bottom wall 22f, respectively. The opening 22a of the heating chamber 22 is formed at the center of the front wall 21a of the housing 21 in the vertical and horizontal directions. The right side wall 22d is provided with a waveguide (not shown).

0020The region inside the housing 21 and outside the heating chamber 22 facing the rear wall 22b to the right side wall 22d is hereinafter referred to as a low temperature region 23b to 23d. The regions inside the housing 21 and outside the heating chamber 22 facing the top wall 22e and the bottom wall 22f are hereinafter referred to as high temperature regions 23e and 23f.

0021The storage body 3 has a drawer shape capable of storing food to be cooked (for example, food), and has a door 31 corresponding to the front plate of the drawer, side plate portions 32 and 33 corresponding to the left and right end plates, and a spine corresponding to the front plate. It integrally has a plate portion 34 and a bottom plate portion 35 corresponding to the bottom plate. The upper surface of the bottom plate portion 35 is a mounting surface on which the food to be cooked is placed.

0022The lengths of the side plate portions 32 and 33 and the bottom plate portions 35 in the front-rear direction are shorter than the depth of the heating chamber 22. The length of each of the back plate portion 34 and the bottom plate portion 35 in the left-right direction is shorter than the length in the left-right direction of the opening 22a of the heating chamber 22. The vertical length of each of the side plate portion 32 to the back plate portion 34 is shorter than the vertical length of the opening 22a. Vertical and horizontal length of the door 31, the upper and lower left of the opening 22a of the right direction longer than the length. When the door 31 closes the opening 22a of the heating chamber 22, the side plate portions 32, 33, the back plate portion 34, and the bottom plate portion 35 are housed in the heating chamber 22. No microwaves leak from the heating chamber 22 in which the opening 22a is closed by the door 31.

0023The storage body 3 is supported by slide rails 41 to 43 so as to be able to appear and disappear from the inside of the heating chamber 22. The projecting direction / immersion direction of the housing body 3 with respect to the heating chamber 22 is the front direction (the direction of the white arrow in FIGS. 2 and 3) / the rear direction. The slide rails 41 and 42 are arranged in the low temperature region 23c and 23d. The slide rail 43 is arranged on the inner surface of the bottom wall 22f of the heating chamber 22. The slide rail 41 has a fixed rail 411 and a movable rail 412. The fixed rail 411 is attached to the inner surface of the left side wall 21c of the housing 21 in a lateral position in the front-rear direction. The movable rail 412 is attached to the right side of the fixed rail 411 so as to be slidable in the front-rear direction, and penetrates an opening provided in the front wall 21a of the housing 21.

0024The slide rail 42 has a fixed rail 421 and a movable rail 422. The fixed rail 421 is attached to the inner surface of the right side wall 21d of the housing 21 in a lateral position in the front-rear direction. The movable rail 422 is attached to the left side of the fixed rail 411 so as to be slidable in the front-rear direction, and penetrates an opening provided in the front wall 21a of the housing 21. The front ends of the movable rails 412 and 422 of the slide rails 41 and 42 are attached to the door 31 of the storage body 3.

0025The slide rail 43 has a fixed rail 431 and a movable rail 432. The fixed rail 431 is attached to the inner surface of the bottom wall 22f of the heating chamber 22 in a lateral position in the front-rear direction. The movable rail 432 is attached to the upper side of the fixed rail 411 so as to be slidable in the front-rear direction, and penetrates an opening (not shown) provided in the front wall 21a of the housing 21. The movable rail 432 of the slide rail 43 is attached to the outer surface of the bottom plate portion 35 of the storage body 3. Since the slide rail 43 is arranged inside the heating chamber 22, it is made of a material having higher heat resistance than the slide rails 41 and 42 arranged outside the heating chamber. For example, the slide rails 41 and 42 are made of synthetic resin, and the slide rail 43 is made of metal.

0026The rack gear 44 and the pinion gear 45 are made of synthetic resin and are arranged in the low temperature region 23d. The rack gear 44 is attached to the movable rail 422 of the slide rail 42 in a lateral position in the front-rear direction. The teeth of the rack gear 44 are facing down. The pinion gear 45 meshes with the rack gear 44 from below in a vertical posture in the front-rear direction. However, FIG. 2 shows a state in which the teeth of the rack gear 44 are facing upward and the pinion gear 45 is engaged with the rack gear 44 from above in order to make the figure easier to see.

0027The motor 46 is an actuator for infesting the housing body 3, and is arranged in the low temperature region 23d in a posture in which the output shaft 46b protrudes to the right from the housing 46a. The housing 46a may be mounted inside the bottom wall 21f of the housing 21, or may be mounted on the outer surface of the right side wall 22d of the heating chamber 22. A heat insulating portion (not shown) may be arranged in order to suppress heat transfer from the housing 21 or the heating chamber 22 to the housing 46a. A pinion gear 45 is attached to the output shaft 46b of the motor 46. When the output shaft 46b of the motor 46 rotates, the pinion gear 45 rotates accordingly.

0028The rotational movement of the pinion gear 45 is a linear movement in the front-rear direction of the rack gear 44. At this time, the movable rail 422 of the slide rail 42 slides along the fixed rail 421. The sliding of the movable rail 422 is transmitted to the slide rails 41 and 43 via the housing body 3, and the movable rails 412 and 432 slide along the fixed rails 411 and 431. As the movable rails 412 to 432 slide along the fixed rails 411 to 431, the storage body 3 protrudes from the inside of the heating chamber 22 and immerses itself in the inside of the heating chamber 22. As the storage body 3 appears and disappears, the rack gear 44 appears and disappears in the low temperature region 23d.

0029The slide rails 41 and 42 correspond to the two double-sided slide rails provided in the conventional pull-out type cooker, and the slide rail 43 corresponds to the lower slide rail provided in the conventional pull-out type cooker. However, in the conventional pull-out type heating cooker, the rack gear 44, the pinion gear 45, and the motor 46 are arranged with respect to the lower slide rail, but in the heating cooker 1, the rack gear 44 , The pinion gear 45, and the motor 46 are arranged for one of the two slide rails on both sides.

0030The fixed rails 411 and 421 of the slide rails 41 and 42 may be attached to the outer surfaces of the left side wall 22c and the right side wall 22d of the heating chamber 22 via a heat insulating portion (not shown). In this case, the motor 46 is attached to, for example, the inner surface of the left side wall 21c of the housing 21. Further, instead of the slide rails 41 to 43, two left and right slide rails corresponding to the slide rails 41 and 42 may support the storage body 3. In this case, it is not necessary to provide the slide rail 43 having high heat resistance.

0031The magnetron 51 is an electromagnetic wave generating unit that emits microwaves. The magnetron 51 is arranged in the low temperature region 23b. The magnetron 51 may be arranged in the low temperature region 23d.

0032The waveguide 52 is arranged in the low temperature regions 23b and 23d from the magnetron 51 to the waveguide provided on the right side wall 22d of the heating chamber 22. The microwave emitted by the magnetron 51 is guided to the waveguide 52, passes through the waveguide, and propagates inside the heating chamber 22.

0033The waveguide 52 may be arranged from the magnetron 51 over an antenna chamber (not shown) arranged in the low temperature region 23b. Microwaves guided from the magnetron 51 to the antenna chamber by the waveguide 52 are scattered inside the heating chamber 22 by a movable antenna (not shown) housed in the antenna chamber.

0034The heater 53 includes a heater main body 531 made of one metal tube bent as appropriate, and laterally-positioned tubular non-heating portions 532 and 532 attached to one end and the other end of the heater main body 531. Have one. The non-heating portions 532 and 532 penetrate the left side wall 22c of the heating chamber 22 and are supported by the left side wall 22c. A feeder (not shown) that supplies power to the heater main body 531 is arranged outside the heating chamber 22, and is electrically connected to the heater main body 531 through the inside of the non-heating portions 532 and 532. The heater body 531 has a shape in which one of the four sides of the rectangle meanders inside the rectangle.

0035The heater 53 is arranged in the vicinity of the top wall 22e of the heating chamber 22 (at least on the top wall 22e side of the central portion in the vertical direction of the heating chamber 22). The heater main body 531 is arranged so as to be parallel to the mounting surface of the storage body 3 and at a position higher than the height of the object to be cooked mounted on the mounting surface of the storage body 3. On the top wall 22e side of the heater 53 inside the heating chamber 22, a heat reflecting portion (not shown) that reflects the heat generated by the heater 53 downward is arranged. The heater body 531 may be configured by using a glass tube.

0036Unlike the conventional pull-out type cooker, the cooker 1 as described above is provided with a heater 53 in addition to the magnetron 51 and the waveguide 52, so that the cooker 1 has not only a microwave oven function but also a grill function. And / or it is configured as a multifunctional type that also has an oven function and the like. The cooking cooker 1 may also have a convection oven function. In this case, the heating cooker 1 further includes a blower and an air circulation path for sucking out the air inside the heating chamber heated by the heater 53 by the blower of the blower and blowing the sucked air into the inside of the heating chamber. ..

0037Since the heat generated by the heater 53 is particularly easily transferred downward, the high temperature region 23f is the hottest during the heat generation of the heater 53, and then the high temperature region 23e near the heater 53 is the hottest. Compared with the high temperature regions 23e and 23f, the low temperature regions 23b to 23d are colder. The rack gear 44, the pinion gear 45, the motor 46, and the magnetron 51 are inexpensive and have low heat resistance. If these are arranged in the high temperature regions 23e and 23f, inconveniences due to high temperature (melting of the rack gear 44 or the pinion gear 45, damage to the motor 46, etc.) may occur. However, since these are arranged in the low temperature region 23b to 23d, there is no particular problem.

0038The waveguide 52 is arranged in the low temperature regions 23b and 23d. This is because, if the waveguide 52 is arranged in the high temperature region 23e, the heat transferred to the magnetron 51 via the waveguide 52 may cause inconvenience due to the high temperature in the magnetron 51. The waveguide of the heating chamber 22 may be provided on the rear wall 22b or the bottom wall 22f. In this case, the waveguide 52 is arranged in the low temperature region 23b or the high temperature region 23f from the magnetron 51 to the waveguide provided in the heating chamber 22. A plurality of waveguides 52 may be provided. For example, a waveguide is provided in each of the left side wall 22c and the right side wall 22d of the heating chamber 22, and two waveguides 52 and 52 are provided from the magnetron 51 to the left side wall 22c and in the low temperature region 23c and 23d. It is distributed over the waveguide on the right side wall 22d.

0039The cooker 1 does not need to be equipped with a rack gear 44, a pinion gear 45, a motor 46, and a magnetron 51, which are highly heat-resistant and expensive, and a waveguide 52, which has a low heat transfer property, and therefore should be manufactured inexpensively. Can be done. If the rack gear 44, the pinion gear 45, the motor 46, the magnetron 51, and the waveguide 52 are the same as those provided in the conventional pull-out cooker, the manufacturing cost of the cooker 1 is further reduced. be able to.

0040Embodiment 2. FIG. 4 is a plan view schematically showing the internal configuration of the cooking cooker 1 according to the second embodiment of the present invention. 5 and 6 are side views schematically showing the internal configuration of the cooking cooker 1. FIG. 5 shows a case where the storage body 3 protrudes from the inside of the heating chamber 22, and FIG. 6 shows a case where the storage body 3 is immersed in the inside of the heating chamber 22. 4 and 5 and 6 correspond to FIGS. 2 and 3 of the first embodiment. However, in FIGS. 4 to 6, the slide rail 43, the rack gear 44, the pinion gear 45, the motor 46, the magnetron 51, and the waveguide 52 are not shown. The cooker 1 of the present embodiment has substantially the same configuration as the cooker 1 of the first embodiment. Hereinafter, the differences from the first embodiment will be described, and other parts corresponding to the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

0041The cooking cooker 1 includes a heater 54 instead of the heater 53 of the first embodiment. The heater 53 is fixed, while the heater 54 is movable. The heater 54 includes a heater main body 541 using a single metal tube bent appropriately, non-heating portions 542, 55 attached to one end and the other end of the heater main body 541, and an urging portion 543. And integrally.

0042The heater main body 541 corresponds to the heater main body 531 of the first embodiment, but the shape of the heater main body 541 is U-shaped, U-shaped, or the like. The heater main body 541 is movably supported by the left side wall 22c and the right side wall 22d of the heating chamber 22 via the non-heating portions 542 and 55. The heater main body 541 swings as the storage body 3 appears and disappears. The swing range of the heater main body 541 is near the top wall 22e of the heating chamber 22 (at least on the top wall 22e side of the central portion in the vertical direction of the heating chamber 22. For example, the arrangement position of the heater main body 531 in the first embodiment) and the storage. It is between the body 3 and the side on which the object to be cooked is placed (the upper surface of the bottom plate portion 35).

0043The heater main body 541 on the top wall 22e side is arranged parallel to the mounting surface of the storage body 3 and at a position higher than the height of the object to be cooked mounted on the mounting surface of the storage body 3. The heater body 541 on the mounting surface side is in a backward tilted posture with the front side lowered as compared with the case where it is on the top wall 22e side. The heater main body 541 on the mounting surface side surrounds the front and the left and right sides of the object to be cooked mounted on the mounting surface of the storage body 3.

0044The non-heating portion 542 has a horizontal tubular shape. The non-heating portion 542 penetrates the left side wall 22c of the heating chamber 22 and is rotatably supported by the left side wall 22c around its own axis. The non-heating portion 55 integrally includes a rotating portion 551 and a swinging portion 552. The rotating portion 551 has a tubular shape in a horizontal posture. The rotating portion 551 penetrates the right side wall 22d of the heating chamber 22 and is rotatably supported by the right side wall 22d around its own axis. The heater main body 541 swings as the non-heating portion 542 and the rotating portion 551 rotate.

0045The swinging portion 552 projects from the right end portion of the rotating portion 551 (that is, the outer end portion of the heating chamber 22 in the rotating portion 551) in the low temperature region 23d. The projecting direction of the swinging portion 552 is orthogonal to the axial length direction of the rotating portion 551 and is generally downward. As the rotating portion 551 rotates, the swinging portion 552 swings between the first position (see FIG. 5) in the vertical posture and the second position (see FIG. 6) in the forward leaning posture. .. The urging portion 543 is formed by using, for example, a spiral spring, and is attached to the rotating portion 551 in the low temperature region 23d. The urging portion 543 urges the rotating portion 551 so that the rotating portion 551 rotates in a predetermined direction. When the rotating portion 551 rotates in a predetermined direction, the heater main body 541 swings toward the top wall 22e of the heating chamber 22, and the swinging portion 552 swings toward the first position.

0046A feeder (not shown) that supplies power to the heater main body 541 is arranged outside the heating chamber 22, and is electrically connected to the heater main body 541 through the inside of the non-heating portions 542 and 55.

0047The movable rail 422 of the slide rail 42 is provided with a contact / detachment portion 56. The contact / detachment portion 56 has a plate shape in a vertical posture along the front-rear direction, and projects upward from the rear end portion of the movable rail 422. A horizontal plane is provided on the upper portion of the contacting / separating portion 56 from the front side to the central portion in the front-rear direction, and an inclined surface that is lowered toward the rear side is provided from the central portion in the front-rear direction to the rear portion.

0048The contacting / separating portion 56 separates / approaches the swinging portion 552 of the non-heating portion 55 as the movable rail 422 moves forward / backward (that is, the housing body 3 moves forward / backward). When the door 31 is closed due to the immersion of the storage body 33, the rear end portion of the inclined surface of the contact / detachment portion 56 comes into contact with the lower end portion of the swing portion 552, and the movable rail 422 moves further rearward, so that the contact / detachment portion 56 An external force is gradually applied to the swinging portion 552. This external force overcomes the urging force of the urging portion 543, causes the oscillating portion 552 to oscillate toward the second position side, and rotates the rotating portion 551 in the opposite direction in a predetermined direction via the oscillating portion 552. Let me. As a result, the heater main body 541 swings toward the mounting surface side of the storage body 3 immersed inside the heating chamber 22.

0049The urging portion 543, the swinging portion 552, and the contacting / detaching portion 56 as described above move the heater 54 to the top wall 22e side of the heating chamber 22 / the storage position of the object to be cooked in conjunction with the coming / going of the storage body 3. It functions as a swing mechanism 57 that swings to the side.

0050The cooking cooker 1 as described above has the same function and effect as the cooking cooker 1 of the first embodiment, and appropriately heats the object to be cooked by the movable heater 54. Since the heater 54 automatically swings as the storage body 3 appears and disappears, the user does not need to swing it manually. That is, the convenience of the user is improved. In the present embodiment, the housing body 3 is driven by the motor 46 and appears and disappears. That is, it is not necessary to separately provide an actuator for swinging the heater 54. It should be noted that a configuration may be configured in which an actuator for swinging the heater 54 is separately provided.

0051When the storage body 3 is immersed in the heating chamber 22, the contact / detachment portion 56 contacts the swing portion 552, and the heater 54 swings to the mounting surface side of the heating chamber 22 via the swing portion 552. Let me. At this time, since the separation distance between the heater 54 and the object to be cooked placed on the mounting surface of the heating chamber 22 is shortened, the object to be cooked is efficiently heated. On the other hand, when the storage body 3 protrudes from the inside of the heating chamber 22, the contacting / separating portion 56 separates from the swinging portion 552, and the urging portion 543 swings the heater 54 toward the top wall 22e of the heating chamber 22. Let me. At this time, since the separation distance between the heater 54 and the object to be cooked placed on the mounting surface of the heating chamber 22 becomes long, the heater is applied to the object to be cooked that appears and disappears from the inside of the heating chamber 22 together with the storage body 3. Interference with 54 is suppressed.

Further, the magnetron 51 is not shown in FIG. 7, and the slide rail 42, the rack gear 44, the pinion gear 45, and the motor 46 are not shown in FIG.

0053The cooker 1 of the present embodiment has substantially the same configuration as the cooker 1 of the first embodiment. Hereinafter, the differences from the first embodiment will be described, and other parts corresponding to the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

0054The waveguide of the heating chamber 22 is provided on the top wall 22e. The back plate portion 34 of the storage body 3 has an opening 341 at the lower portion. The motor 46 is arranged in the low temperature region 23d in a posture in which the output shaft 46b protrudes to the left from the housing 46a. The housing 46a is attached to the inner surface of the right side wall 21d of the housing 21. The waveguide 52 is arranged in the low temperature region 23b and the high temperature region 23e from the magnetron 51 to the waveguide provided on the top wall 22e of the heating chamber 22.

0055The cooking cooker 1 includes a heater 58 instead of the heater 53 of the first embodiment. The heater 58 integrally includes a heater main body 581 and non-heating portions 582,582. These correspond to the heater main body 531 and the non-heating portions 532, 532 of the first embodiment. The shape of the heater body 581 is a single-stroke double U-shape or U-shape.

When the storage body 3 is immersed in the heating chamber 22, the heater main body 581 surrounds the rear side and the left and right sides of the object to be cooked to be placed on the mounting surface of the storage body 3.

0057The cooking cooker 1 as described above has the same effect as that of the first embodiment. By the way, the waveguide 52 in the present embodiment is arranged in the high temperature region 23e. However, the waveguide 52 has higher heat resistance than, for example, the rack gear 44, the pinion gear 45, the motor 46, and the like. Moreover, since the heater 58 is separated from the high temperature region 23e, the temperature of the high temperature region 23e is lower than that of the first embodiment even while the heater 58 is generating heat. Therefore, even if heat is transferred to the magnetron 51 via the waveguide 52, the inconvenience caused by the high temperature does not occur in the magnetron 51. The arrangement of the waveguide 52 may be the same as the arrangement of the first embodiment.

0058Embodiment 4. FIG. 9 is a plan view schematically showing the internal configuration of the cooking cooker 1 according to the fourth embodiment of the present invention. FIG. 9 corresponds to FIG. 2 of the first embodiment. However, the slide rails 42 and 43, the rack gear 44, the pinion gear 45, and the motor 46 are not shown.

The output shaft of the drive unit 62 penetrates the partition wall separating the antenna chamber 661 and the drive chamber 662, and is connected to the center position of the movable antenna 61 inside the antenna chamber 661. The drive unit 62 drives the movable antenna 61. That is, when the output shaft of the drive unit 62 rotates, the movable antenna 61 rotates.

0060The waveguide 52 is arranged from the magnetron 51 to the antenna chamber 661 in the low temperature regions 23b and 23d. The microwave emitted by the magnetron 51 is guided by the waveguide 52 and scattered inside the heating chamber 22 by the movable antenna 61 rotating in the antenna chamber 661.

0061The blower unit 63 blows air for cooling. The ventilation passage 64 is arranged over the ventilation unit 63, the magnetron 51, and the drive chamber 662, respectively. The air blown by the blower unit 63 is blown to the magnetron 51 and the drive unit 62 through the ventilation passage 64 to cool them. Therefore, the abnormal heat generation of the magnetron 51 or the drive unit 62 and the occurrence of inconvenience related to the magnetron 51 or the drive unit 62 due to the abnormal heat generation are suppressed. The air blown by the blower unit 63 may be blown not only to the magnetron 51 and the drive unit 62 but also to the motor 46.

It is characterized in that it is arranged in the low temperature regions 23b, 23c, 23d or in the high temperature regions 23e, 23f facing the bottom wall 22f.

0066In the heating cooker 1 according to the present invention, the heater 54 can swing between the top wall 22e side inside the heating chamber 22 and the storage position side of the object to be cooked lower than the top wall 22e side. It is characterized in that the heater 54 is provided with a swing mechanism 57 that swings the heater 54 toward the top wall 22e side / the storage position side in conjunction with the opening / closing of the storage body 3.

0067In the heating cooker 1 according to the present invention, the storage body 3 integrally has a door 31 for opening and closing the opening 22a, and the swing mechanism 57 swings together with the heater 54. With respect to the heater 54, the urging portion 543 that urges the heater 54 in the direction of swinging toward the top wall 22e, and the swinging portion 552 as the accommodating body 3 moves in and out. When the door 31 is separated / approached and the door 31 is closed, the heater 54 comes into contact with the swinging portion 552 and applies an external force to the swinging portion 552 in a direction in which the heater 54 swings toward the storage position. It is characterized by having.

0068In the heating cooker 1 according to the present invention, the heaters 53 and 54 are arranged on the top wall 22e side inside the heating chamber 22, and the microwaves guided by the waveguide 52 are transferred to the heating chamber 22. A movable antenna 61 that scatters inside, a drive unit 626 that drives the movable antenna 61, a blower unit 63, and ventilation for guiding the air blown by the blower unit 63 to the magnetron 51 and the drive unit 626, respectively. The movable antenna 61, the drive unit 626, the blower unit 63, and the ventilation passage 64 are provided on the rear wall 22b or the left side wall 22c (right side wall 22d) of the heating chamber 22 outside the heating chamber 22. It is characterized in that it is arranged in the opposite low temperature regions 23b, 23c, 23d.

0069The heating cooker 1 according to the present invention is attached to a slide rail 42 that supports the storage body 3 so as to be able to appear and disappear, and a rack gear 44 that is attached to the slide rail 42 and appears and disappears together with the storage body 3 and the rack gear 44. The meshing pinion gear 45 is further provided in the low temperature regions 23c and 23d facing the left side wall 22c (right side wall 22d) of the heating chamber 22 outside the heating chamber 22, and the motor 46 provides the pinion gear 45. It is a rotationally driven motor, and is characterized in that it is arranged in the low temperature regions 23c and 23d facing the left side wall 22c (right side wall 22d).

0070In the present invention, the heater is arranged on the top wall side or the bottom wall side inside the heating chamber. Therefore, the heat generated by the heater is easily transferred to the region facing either the top wall or the bottom wall of the heating chamber outside the heating chamber (that is, this region is a high temperature region). Parts placed in the high temperature region need to have high heat resistance. On the other hand, it is difficult to transfer the heat generated by the heater to a region other than the high temperature region (that is, this region is a low temperature region). Actuators located in the cold region do not require high heat resistance.

0071In the present invention, the electromagnetic wave generating portion is arranged in a low temperature region facing the rear wall or side wall of the heating chamber. The electromagnetic wave generating portion arranged in the low temperature region does not need to have high heat resistance. On the other hand, the waveguide is arranged in a low temperature region facing the rear wall or side wall of the heating chamber, or in a high temperature region facing the bottom wall of the heating chamber. This is a configuration in which the waveguide arranged above the heating chamber in the conventional heating cooker is retracted from the high temperature region facing the top wall of the heating chamber.

0072In general, a waveguide is less likely to cause inconvenience due to high temperature than a rack gear, a pinion gear, a motor, an electromagnetic wave generating portion, etc. provided in a conventional cooking cooker. Further, since the high temperature region facing the bottom wall of the heating chamber does not become as hot as the high temperature region facing the top wall of the heating chamber, even if high heat is transmitted to the electromagnetic wave generating portion via the waveguide, it depends on the high temperature. Inconvenience is unlikely to occur in the electromagnetic wave generating part. Therefore, there is no particular problem even if the waveguide is arranged in a high temperature region facing the bottom wall of the heating chamber. As a result, it is possible to inexpensively manufacture a cooking cooker by using an inexpensive electromagnetic wave generating unit and a waveguide having the same low heat resistance as the conventional one.

0073In the present invention, the heater provided in the cooking cooker is a movable heater. The swing of the heater is linked to the appearance and appearance of the storage body. Therefore, it is not necessary for the user to manually swing the heater.

0074In the present invention, when the accommodating body is immersed in the inside of the heating chamber, the contact / detachment portion contacts the rocking portion, and the heater is moved through the rocking portion to the cooked object inside the heating chamber. Swing to the storage position side. That is, the heater is on the side of the storage position of the object to be cooked inside the heating chamber when the storage body is immersed in the heating chamber. Therefore, since the separation distance between the heater and the object to be cooked is short, the object to be cooked is efficiently heated.

0075On the other hand, when the storage body protrudes from the inside of the heating chamber, the contacting / separating portion separates from the swinging portion, and the urging portion swings the heater toward the top wall inside the heating chamber. That is, the heater is on the top wall side of the heating chamber when the storage body protrudes from the heating chamber. Therefore, since the separation distance between the heater and the object to be cooked is long, it is possible to prevent the heater from interfering with the object to be cooked that appears and disappears in the heating chamber together with the storage body. In the above configuration, an actuator for automatically swinging the heater is unnecessary.

0076In the present invention, the blower unit suppresses the temperature rise of these by blowing air to the electromagnetic wave generation unit and the drive unit.

0077In the present invention, the slide rail, the rack gear, the pinion gear, and the motor as an actuator are arranged in a low temperature region facing the side wall of the heating chamber. This is a configuration in which the rack gear, the pinion gear, and the motor arranged on the lower slide rail in the conventional cooking cooker are moved to at least one of the slide rails on both sides. The slide rails, rack gears, pinion gears, and motors arranged in the low temperature region do not need to have high heat resistance, so even if they are inexpensive and have the same low heat resistance as before, they are particularly There is no problem. As a result, the cooking cooker can be manufactured at low cost.

0078The embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive. The scope of the present invention is not intended to include the meaning described above, but is intended to include the meaning equivalent to the scope of claims and all modifications within the scope of claims. Further, as long as the effect of the present invention is effective, the cooking cooker 1 may include components not disclosed in the first to fourth embodiments.
