BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1. FIG. 1 is a perspective view of a main part showing a washing machine according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of FIG. The water tank part 3 to put in is a top cover covering the upper part of the water tank part 2, and an opening 3a for putting laundry is provided in the central part. Reference numeral 4 denotes a lid that closes the opening 3a, and forms a monitoring window 5. The lid 4 is supported by the top cover 3 and the rotation fulcrum 4a so as to be openable and closable. Reference numeral 6 denotes a cleaning device arranged on the surface of the lid 4 at a position facing the opening 3a. Reference numeral 21 is a switch described later.

【0014】

Next, the configuration of the cleaning device 6 will be described. FIG. 3A is a perspective view of the cleaning device 6, FIG. 3B is an exploded perspective view of the cleaning device 6, FIG. 7 is a boiler, and a tube guide 9 to which the flexible tube 8 is connected and supports the flexible tube 8 Rotational motion to the rotation fulcrum 10 of the tube guide 9 rotatably supported by the lid 4, the cam groove 11 which is the driven node that determines the support angle of the tube guide 9, the cam 12 and the cam 12 which are the driving nodes that come into contact with the cam groove 11. It is composed of a motor 13 and a rotating shaft 14 of the motor 13.

【0015】

The operation of the washing machine provided with the washing device 6 configured in this way will be described with reference to FIGS. 3, 4, and 5. Fig. 4 is a cross-sectional view of the washing machine with the laundry set, Fig. 5 is a configuration diagram showing the internal configuration of the boiler, 15 is the edge of the top cover on the back of the laundry, and 16 is the water from the water pipe etc. A water pipe that supplies water to boiler 7, 17 is a valve that controls ON / OFF of water injection, 18 is a heater that heats boiler 7, 19 is a power supply that connects to heater 18, 20 is water and steam that has entered boiler 7. A jet nozzle attached to the outlet of the flexible tube 8 through which the valve 17 passes, 21 is a switch that works with OFF when the valve 17 is open and ON when the lid 4 is closed, and 22 is located at a position facing the jet nozzle 20. It is the laundry that has been done.

【0016】

First, the laundry 22 is sandwiched between the lid 4 and the top cover 3 with the dirty portion of the laundry 22 such as the collar and sleeves facing up, and the laundry 22 is arranged so as to face the jet nozzle 20. At this time, by closing the lid 4, the switch 21 is turned on and the valve 17 is opened. Then, the power supply 19 is turned on to the heater 18 to supply electric power, and the boiler 7 is heated to 100 degrees or more. Then, since the valve 17 is in the open state, tap water is supplied to the boiler 7 via the water supply pipe 15. The water inside the boiler 7 boils and becomes steam. In this way, when water becomes steam, the vapor pressure rises and the inside of the boiler 7 becomes high pressure. Then, due to this pressure, steam and hot water inside the boiler 7 are ejected from the injection hole (not shown) at the tip of the jet nozzle 20. Since the injection hole (not shown) at the tip of the jet nozzle 20 is arranged at a position facing the edge 15 of the top cover 3, water vapor and hot water ejected from the jet nozzle 20 are placed on the edge 15 of the top cover 3. It surely collides with a certain laundry 22 and removes the dirt 22a of the laundry 22. If a commercially available detergent is applied to the dirt 22a portion of the laundry 22 in advance, the dirt 22a is dissolved and the dirt can be easily removed.

【0017】

When the water vapor and hot water ejected from the jet nozzle 20 collide with the laundry 22, they bounce and scatter in all directions, but the water vapor and hot water scattered upward are blocked by the lid 4 and condense on the lid 4 and enter the water tank 2. Since it falls, it does not jump out of the washing machine body 1.

【0018】

Here, the irradiation distance L (see FIG. 5) between the jet nozzle 20 of the cleaning device 6 and the laundry 22 will be described. Based on the JIS electric washing machine C9606 cleaning test, when the degree of cleaning (%) is calculated using an artificially contaminated cloth (simulating collar stains) as the laundry 22 as the laundry 22, the result is as shown in Fig. 6. .. The degree of cleaning (%) is calculated by the reflectance method using the formula: degree of cleaning (%) = (reflectance after cleaning-reflectance before cleaning) / (reflectance of raw cloth-reflectance before cleaning) x 100.

【0019】

As a condition of the experiment, the heater 18 of the boiler 7 was used with an output of 1350 W, and the cleaning liquid was supplied with tap water adjusted to 22 ° C at a rate of 100 g per minute to the boiler 7 and commercially available on a contaminated cloth in advance. An appropriate amount of liquid detergent for partial washing was applied. The jet nozzle 20 had a hole diameter of 2 mm.

【0020】

Looking at the results of this experiment, it is possible to obtain 40% of the degree of washing that can be obtained by normal washing machine washing at an irradiation distance of 65 mm. Therefore, the irradiation distance L between the jet nozzle 20 and the laundry 22 can be separated up to 65 mm, and a remarkable cleaning effect can be obtained. Since the dirty portion can be washed even at a distance of up to 65 mm in this way, the condition of the thickness of the laundry 22 can be broadened. It can be done in an extremely short time of 0.15 seconds until the dirt cleaning of the cloth surface irradiated with steam and warm water is completed.

【0021】

Next, the amount of water vapor and water supplied from the jet nozzle 20 will be described. Similar to the above, the cleaning test was performed by changing the opening / closing amount of the valve 17 and changing the amount of water supplied, with the irradiation distance L being 10 mm and the irradiation time per jet water flow cross-sectional area being 0.3 seconds, as shown in FIG. I got a good result. The reason why the irradiation distance L was set to 10 mm is that the degree of cleaning did not change much at the irradiation distance L between 0 and 10 mm due to the change in the degree of cleaning in FIG. 6, and a high degree of cleaning of less than 46% was obtained. Therefore, the experiment was conducted with an irradiation distance of L of 10 mm. As a result, the degree of washing of 40% obtained by ordinary washing machine washing can be obtained with a water amount of 30 g per minute, and washing can be performed with an extremely small flow rate of water.

【0022】

Further, as shown in FIG. 7, when the water supply flow rate to the boiler 7 is 70 g or more, the degree of cleaning tends not to increase, and the water supply beyond this tends to be wasted, so that the water supply of 70 g or more is not necessary. This is affected by the relationship with the ability of the boiler 7 to produce water vapor, but the degree of cleaning is 55% or more, which is more than the required degree of cleaning, so a water supply of 70 g or less is sufficient.

【0023】

Therefore, according to the configuration of the washing machine provided with the washing device 6 described in the first embodiment, a partially dirty surface such as a collar or a cuff is placed between the lid 4 and the top cover 3 at the edge 15 of the top cover 3. By arranging the laundry 22 so as to come to the portion of the washing machine 22 and arranging the jet nozzle 20 of the cleaning device 6 at a position facing the edge 15 of the top cover 3, steam and hot water are injected from the jet nozzle 20. It is possible to wash the dirty part by colliding with the laundry 22, and when the lid 4 is opened, the valve 17 closes in conjunction with it, so the water supply stops and the injection of water vapor and hot water from the jet nozzle 20 also stops. Therefore, it does not blow steam or hot water to the user. In addition, since the valve 17 opens with the lid 4 closed, when the washing device 6 is used, the lid 4 is closed to wash the laundry 22, and high-temperature steam scatters to the outside of the washing machine body 1. There is no need to worry about exposing the user to the high temperature of water vapor.

【0024】

Embodiment 2. Further, FIG. 8 shows a washing device 6 arranged in the washing machine main body 1 that rotates, and the movements of the flexible tube 8, the tube guide 9, and the jet nozzle 20 are viewed from above. It is a thing. The configuration of the cleaning device 6 is the same as that of the first embodiment, and the description thereof will be omitted. When electric power is supplied to the motor 13 from the motor power supply 23, the rotating shaft 14 rotates, and the cam 12 attached to the rotating shaft 14 rotates. When the cam 12 rotates, a load is applied to the cam groove 11 and the tube guide 9 moves. The rotary motion of the cam 12 is converted into a reciprocating motion with the rotary fulcrum 10 of the tube guide 9 as the fulcrum via the cam groove 11, and the tube guide 9 repeatedly moves in the direction of the arrow in FIG. At this time, with respect to the laundry 22, so moved so as to trace jet nozzle 20, injection from the jet nozzle 20 so steam and hot water for morphism can hang automatically evenly against a broad range of laundry 22 , The cleaning range can be widened.

【0025】

Further, even if the shape of the opening (not shown) facing the opening 2a of the water tank portion 2 of the top cover 3 sandwiching the laundry 22 is square or circular, it may be different from the laundry 22 depending on the rotation angle of the washing device 6. Although the irradiation distance L of the jet nozzle 20 is separated, as shown in the experimental result of the first embodiment, since a cleaning degree of 40% can be obtained up to an irradiation distance L of 65 mm, the opening shape of the top cover 3 Even if there is a rotation angle at which the irradiation distance L between the jet nozzle 20 and the laundry 22 is separated (distanced) by the rotation of the cleaning device 6, it is possible to perform a wide range of partial washing without reducing the cleaning ability. it can.

【0026】

Embodiment 3. FIG. 9 shows a cross-sectional view of a washing machine according to a third embodiment of the present invention, and the same reference numerals as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. In the figure, 24 is a steam shutter and 25 is a spring. As shown in FIG. 9A, when the lid 4 is opened, the spring 25 pulls down the steam shutter 24 and the injection hole of the jet nozzle 20 (not shown). ) (Injection hole referred to in the claim), and as shown in FIG. 9 (b), when the lid 4 is closed, the steam shutter 24 comes into contact with the upper surface of the top cover 3 from the front of the jet nozzle 20. While moving, the steam shutter 24 opens the front of the injection hole (not shown) of the jet nozzle 20. Therefore, when the lid 4 is opened, if water remains in the boiler 7, even if it is jetted as steam and hot water from the jet nozzle 20, it collides with the steam shutter 24 and goes out of the washing machine main body 1. It is easy to use because it does not pop out and does not scatter to the user.

【0027】

Embodiment 4. FIGS. 10 (a) and 10 (b) are a main part perspective view and an exploded perspective view of a washing device showing a washing machine according to the fourth embodiment of the present invention. In the figure, the same parts as those in the first to third embodiments are designated by the same reference numerals, and the description thereof will be omitted. 26 is made of a flexible material and is formed in a bellows shape, and is a shatterproof cover that surrounds the jet nozzle 20 and extends to the irradiation distance L between the jet nozzle 20 and 27. 27 is the water tank of the shatterproof cover 26. It is a notch portion formed at a position facing the portion 2.

【0028】

In the cleaning device 6 configured in this way, as shown in FIG. 11, the shatterproof cover 26 surrounds the tip of the jet nozzle 20, and the laundry 22 sandwiched between the edge 15 of the top cover 3 and the lid 4. It is also placed between the jet nozzle 20 and the jet nozzle 20 (irradiation distance L), and the water vapor and hot water emitted from the jet nozzle 20 during cleaning collide with the laundry 22 as shown by the solid arrow to remove the dirt. At this time, steam and hot water are scattered. The scattered steam and hot water are reflected by the anti-scattering cover 26 and flow out from the notch 28 as shown by the dotted arrow. That is, the scattering prevention cover 26 is provided by surrounding the irradiation distance L portion from the periphery of the jet nozzle 20 and forming the notch portion 28 serving as an escape route for water vapor at a position facing the water tank portion 2. The scattering range of steam and hot water can be minimized.

【0029】

[Effect of the invention]

Since the present invention is configured as described above, it has the following effects.

【0030】

A washing machine main body having a water tank portion arranged inside, a top cover covering the upper surface of the washing machine main body and having an opening for putting laundry into the water tank portion, and a lid covering the upper surface of the top cover. In the equipped washing machine, a boiler having a heating means and a water supply means for supplying water to the boiler are provided, and steam and water are jetted onto the laundry by utilizing the pressure of steam generated from the boiler. Since it is equipped with a washing device formed by forming a jet nozzle, the washing effect is high because partial washing is performed with steam and warm water, and partial stains on the laundry can be washed only with liquids such as steam and hot water, and it is solid. Since it does not come into contact with the cloth, it is possible to partially wash the cloth without damaging it.

【0031】

Further, since the jet nozzle of the cleaning device is arranged so as to face the end portion forming the opening of the top panel and the laundry is fixedly held between the lid and the top cover, the lid is provided. The laundry can be fixed in the washing machine main body in the closed state, and the water vapor and hot water jetted from the jet nozzle can be surely applied to the partial washing portion of the laundry.

【0032】

Further, since the cleaning device is attached to the surface of the lid on the water tank portion side, steam and hot water ejected from the jet nozzle can be reliably applied to the partial washing portion of the laundry, and when the lid is opened, the cleaning device can be reliably applied. Will move upwards, so it will not get in the way when performing normal washing, and it is easy to use.

【0033】

Further, since the injection direction (angle) of the jet nozzle can be changed, it is possible to perform partial washing over a wide range of laundry.

【0034】

Further, since the OFF / ON of the water supply to the cleaning device is linked to the opening and closing of the lid, water vapor and water are not ejected from the cleaning device when the lid is opened.

【0035】

A steam shutter that shuts off the front surface of the injection hole of the jet nozzle is provided, and the steam shutter shuts off / opens the front surface of the jet slur in conjunction with the opening and closing of the lid. Even if the steam or water remaining in the cleaning device is sprayed, it is blocked by the steam shutter, and the user does not get exposed to steam or water.

【0036】

Further, a shatterproof cover is provided which surrounds the injection hole of the jet nozzle and extends within the irradiation distance between the jet nozzle and the washing machine to form a bellows-shaped tubular shape with a soft material. Since the water vapor scattered in the position facing the water tank and the notch for allowing water to escape are formed, the range of water vapor scattering can be minimized, so that the surroundings inside the washing machine body can be soiled with water. It can be prevented and the user will not be exposed to water vapor or water.
