0036A fabric treating apparatus 100 includes an outside cabinet 111 which forms the exterior of the apparatus and an inside cabinet 112 which is disposed in the outside cabinet 111. A treating chamber 110 is disposed in the inside cabinet 112.

0037The treating chamber 110 has an opening at the side, and thus, a fabric may be loaded in the treating chamber 110 through the opening. The opening side is opened by a door 115. If the door 115 is closed, the treating chamber 110 is isolated from the outside. If the door 115 is opened, the treating chamber 110 is exposed to the outside.

0038The treating chamber 110 is a space for treating a fabric to be changed the physical or chemical properties of the fabrics by supplying a steam or hot wind. Namely, the treating chamber 110 is a space for treating the fabrics by using different method. For example, in the treating chamber 110, the fabrics may be dried by using a hot wind, or the wrinkles of the fabrics may be removed by using a steam, or the fabrics can be supplied aroma by spraying an aromatic, or the generation of static electricity of the fabrics may be prevented by spraying an antistatic.

0039The fabric treating apparatus 100 includes a heating unit 120 for supplying any one between hot wind and steam to the treating chamber 110, a hanger rack 150 disposed in the treating chamber 110, a driving unit 130 which is disposed upper part of the inside cabinet 112 for generating rotary power outside the treating chamber 110, and a transmission unit for reciprocating the hanger rack 150 by transmitting the rotary power of the driving unit 130. Also the transmission unit includes a power transmission unit 140 which transmits the rotary power of the driving unit 130 and a power transformation unit 160 which reciprocates the hanger rack 150 by converting the rotary power of the transmission unit.

0040The transmission unit may be disposed to penetrate the inside cabinet 112 because the transmission unit should reciprocate the hanger rack 150 by transmitting the rotary power generated by the driving unit 130 outside of the treating chamber 110 to inside of the treating chamber 110.

0041Therefore any one between a power transmission unit 140 and a power transformation unit 160 which is included the transmission unit is disposed to penetrate the inside cabinet 112.

0042A heating unit 120 is diposed the bottom of the treating chamber 110. More specifically, the heating unit 120 is disposed between the outside cabinet 111 and the inside cabinet 112. The heating unit 120 is able to heat the air inhaled from the treating chamber 110, and to supply the hot wind to the inside of the treating chamber 110. Also, the heating unit is able to generate a steam by heating the water, and to supply the steam to the inside of the treating chamber 110. Of course, the heating unit 120 is able to supply both the hot wind and the steam. Also, the heating unit 120 is able to supply any one between the hot wind and the steam. The heating unit 120 is variously embodied by those of ordinary skill in the scope of the present invention.

0043The heating unit 120 in accordance with an exemplary embodiment of the present invention includes an air inlet 121 for inhaling the air from the inside of the treating chamber 110, and a heater for heating the air inhaled, and an outlet 122 for discharging the hot wind heated by the heater to the inside of the treating chamber 110, and an injection nozzle for injecting a steam to the inside of the treating chamber 110.

0044The hot wind or the steam generated by the heating unit 120 supplies to the fabrics loaded in the treating chamber 110, and has an influence on the physical property or the chemical property of the fabrics. Namely, the hot wind or the steam makes the structure of the fabrics to be relaxed, so that the wrinkles of the fabrics may be removed. The steam reacts to the smell particles of the fabrics, so that an unpleasant smell may be removed. Also, the hot wind or the steam generated by the heating unit 120 has a sterilization effect on bacteria of the fabrics.

0045The driving unit 130 is disposed the upper part of the outside of the treating chamber 110. The driving unit 130 is disposed between the inside cabinet 112 and the outside cabinet 111. The driving unit 130 may be embodied by a motor generating rotary power. The driving unit 130 may be built in motor frame 113 fixed between the inside cabinet 112 and the outside cabinet 111. The motor frame 113 fixes the driving unit 130 and absorbs the vibrations generated by the driving of the motor 130.

0046Large amount of fabrics may be treated by making enough space because the driving unit 130 is disposed outside of the treating chamber 110. Also if the driving unit 130 is disposed side of the treating chamber, the width of the fabrics treating apparatus is extended, thus the fabrics treating apparatus 120 of the present invention has an advantage to have slim shape by disposing upper part of the inside cabinet 120. The fabrics treating apparatus 120 may be easily installed at the narrow space such as indoor by the slim shape. Also there is an advantage to increase the amount of the fabrics to treat by the enlargement of the inner space of the treating chamber 110 because of installing the driving unit 130 by using the upper part of the outside of the treating chamber 110.

0047The power transmission unit 140 transmits the rotatory power generated by the motor to the power transformation unit 160. The power transmission unit 140 transmits a rotary motion of the one unit to another unit. The power transmission unit 140 is variously embodied by those of ordinary skill in the scope of the present invention.

0048The power transmission unit 140 includes a driving pulley 141 rotating by the motor 130, and a driven pulley 142 rotated by a belt which connects the driving pulley 140 and the driven pulley 142, and a rotary shaft 144 inserted into the driven pulley 142 and rotated by the driven pulley 142.

0049According to an exemplary embodiment, the diameter of the driven pulley 142 is larger than the diameter of the driving pulley 141. The driving pulley 141 rotates with comparatively high speed. If the hanger rack 150 reciprocates same cycle with the rotation cycle generated by the driving unit 130, transient vibration is generated and the driving unit 130 is overloaded, and the efficiency of the hanger rack 150 for treating fabrics is decreased. Therefore, it is desirable to control the reciprocating cycle of the hanger rack 150, through the diameter of the driven pulley 142 is larger than the diameter of the driving pulley 141. The adequate range of the diameter ratio between the driving pulley 141 and the driven pulley 142 is from 1:15 to 1:5.

0050The power transmission unit 140 may include a driving sprocket, a driven sprocket, and a chain, instead of said driving pulley 141, said driven pulley 142 and said belt 143. And besides, the power transmission unit 140 may includes a driving gear, a driven gear, a belt, and so on. Thus, the power transmission unit 140 may be variously embodied.

0051Also, the fabric treating apparatus 100 may further include a bearing unit which is inserted into the rotary shaft 144. The bearing unit 170 may include the bearing housing 172, and a first bearing 171 which is disposed between the rotary shaft 144 and the inside of the bearing housing 172. The bearing unit 170 supports the rotary shaft 144 by being fixed at a motor frame 113, and makes the rotary shaft 144 rotate smoothly. It is desirable for the first bearing 171 to be an oilless bearing so as not to pollute the fabrics in the treating chamber 110.

0052The power transformation unit 160 transforms rotary motion received from the power transmission unit 140 into reciprocating motion of the hanger rack 150. The power transformation unit 160 includes a rotary shaft connector 161 which is connected to the rotary shaft 144 of the power transmission unit 140, a rotary arm which is extended from the rotary shaft connector 161, and a slot connector 163 which is inserted to the slot 152 of the hanger rack 150 and rotates the rotary shaft 144 as projected from the end of the rotary arm 162.

0053The rotary shaft axis 151 is disposed at the end of the power transformation unit 160, and an insert hole 161a in which the rotary shaft 144 is inserted. It is desirable for the rotary arm 162 to be extended through the perpendicular direction with the rotary shaft 144 at the rotary shaft connector 161. The slot connector 163 is extended downward from the end of the rotary arm 162. The slot connector 163 rotates with fixed radius from the rotary shaft 144 as the rotary shaft 144 rotates. If the rotary arm 162 is disposed perpendicular to the rotary shaft 144, the fixed radius would be the length of the rotary arm 162. Refer to the detailed construction of the slot connector 163 for further details.

0054The hanger rack 150 may include a hanger slot 151 on which a hanger 200 is hung, and a slot 152 which is disposed at the middle. The hanger rack 150 reciprocates with being hung on the upper part of the treating chamber 110. Both sides of the hanger rack 150 may be connected to the inner cabinet 112 which constitutes the upper face of the treating chamber or to the motor frame 113 by each supporter 180.

0055It is desirable for the slot 152 to be disposed long with the perpendicular direction to the moving direction of the hanger rack 150. As the reciprocating direction of the hanger rack 150 is the right and left direction, it is explained that the slot is disposed long with the back and forth direction to the following. As the slot 152 is disposed long with the back and forth direction, the movement with back and forth direction is counterbalanced by the slot 152 and the hanger rack 150 reciprocates to the right and left direction, when the slot connector 163 rotates the rotary shaft 144 with being inserted into the slot 152 movement.

0056It is possible for the hanger rack 150 to include a guide instead of the slot 152. It is possible for the guide to make the hanger rack 150 reciprocate by the pushing and pulling force of the power transformation unit 160, as the guide which is made of the rib or the projection differently with an exemplar embodiment of the present invention.

0057The water may be collected into the slot 152, as the moisture of the humid air in the treating chamber 110 is condensed. Therefore it is desirable for the drain hole(not shown) to be disposed at the slot 152 for the collected water to drain outside the slot 152.

0058The supporter 180 includes an elastic material for the hanger rack 150 so as to reciprocate. Specially, the supporter 180 is a long plate which is formed to the direction of back and forth to limit the reciprocating motion of the hanger rack from front to back. One end of the supporter 180 is fixed at the motor frame 113 or the inner cabinet 112, and another end is combined to the one side of the hanger rack 150.

0059A cover 114 may be disposed between the inside cabinet 112 and the hanger rack 150 to hide the power transformation unit 160 so as not to be shown outside.

0060When the treating room 110 is opened, it has an effect on improving the aesthetics of the apparatus and giving a feeling of the high class apparatus for unnecessary structures such as the power transformation unit 160 not to be shown to users.

0061The cover 114 is a separated component from the hanger rack 150 according to an exemplary embodiment of the present invention, but the cover 114 may be disposed in one united body with the slot 151 and the hanger rack 150.

0064The shock absorber 163b removes the impact sound generated between the power transformation unit 160 and the slot 152. For the power transformation unit 160 moves smoothly with being inserted to the slot 152, there should be a prescribed space between the outside surface of the shock absorber 163b and the inside surface of the slot 152. The shock absorber 163b which made from the elastic material such as the rubber contacts elastic with the inside surface of the slot 152 when the hanger rack 150 reciprocates. The shock absorber 163b makes the hanger rack 150 reciprocates smoothly by making the space between the power transformation unit 160 and the slot 152.

0065The shock absorber 163b may be coated in PTFE(Poly Tetre Fluloro Ethylene) in order to reduce the friction with the inside surface of the slot 152. PTFE has the excellent performances on the lubrication and the abrasion resistance to the friction.

The hot wind or the steam supplied into the treating chamber 210 by the heating unit 220 rises upward in the treating chamber 210, and circulates in the treating chamber 210 blown by the fan 230.

0084The fan 230 may be embodied by the cross flow fan which blows the hot wind or the steam which is discharged from the heating unit 220 and is raised to the side direction. The cross flow fan is variously embodied by those of ordinary skill in the scope of the present invention.

0085The hot wind supplied by the heating unit 220 is moisturized as drying the fabrics in the treating chamber 210. The moisturized hot wind flows upward in the treating chamber 210, and is condensed as contacting to the inner wall of the treating chamber 210.

0086Specially, the condensation on the inner wall of the inside cabinet 212 gets stronger when the steam is supplied to the treating room 210 by the heating unit 220. If the condensed water is left after the fabrics treating apparatus working, the apparatus may have the problems because of the unsanitary conditions that the bad smell and the bacteria are generated. The fan 230 prevents forming the condensed water by circulating the air inside of the treating chamber 210, and maintains the cleanness of the inside of the treating chamber 210.

0087When the fabrics treating apparatus is not operated for a long time, the fan 230 is operated intermittently by automatically or manually for the air in the treating chamber 210 so as to be ventilated or dried.

0088The air in the treating chamber 210 may flow uniformly by the fan 230, the fabrics in the treating chamber 210 may be treated effectively by supplying the hot wind or the steam uniformly.

0089Refer <figref idref="f0008">FIG. 9</figref>, the power unit 250 includes the driving unit 251 which generates the rotary power, and the power transmission unit which transmits the rotary power generated by the driving unit 251 to the power transformation unit 260. The power transmission unit may include the driving pulley 252 rotated by the driving unit 251, the driven pulley 252 rotated by the belt 253 which connects the driving pulley 252, and the rotary shaft 255 inserted into the driven pulley 254 and rotated by the driven pulley 254.

0090According to an exemplary embodiment, the diameter of the driven pulley 254 is larger than the diameter of the driving pulley 252. The driving pulley 252 rotates with comparatively high speed because of receiving the rotary power directly. If the hanger rack 240 reciprocates same cycle with the rotation cycle generated by the driving unit 251, transient vibration is generated and the driving unit 251 is overloaded, and the efficiency of the hanger rack 240 for treating fabrics is decreased. Therefore, it is desirable to control the reciprocating cycle of the hanger rack 240, through the diameter of the driven pulley 254 is larger than the diameter of the driving pulley 252. The adequate range of the diameter ratio between the driving pulley 252 and the driven pulley 254 is from 1:15 to 1:5.

0091The power transmission unit may include a driving sprocket, a driven sprocket, and a chain, instead of said driving pulley 252, said driven pulley 254 and said belt 253. And besides, the power transmission unit may include a driving gear, a driven gear, a belt, and so on. Thus, the power transmission unit may be variously embodied.

0092Also, the fabric treating apparatus 200 may further include a bearing unit which is inserted into the rotary shaft 255. The bearing unit may include the bearing housing 257, and a bearing 256 which is disposed between the rotary shaft 255 and the inside of the bearing housing 257. The bearing unit supports the rotary shaft 255 by being fixed at a motor frame 213, and makes the rotary shaft 255 rotate smoothly. It is desirable for the bearing 256 to be an oilless bearing so as not to pollute the fabrics in the treating chamber 210.

0093The power transformation unit 260 transforms rotary motion received from the power transmission unit 251 into reciprocating motion of the hanger rack 240. The power transformation unit 260 includes a rotary shaft connector 261 which is connected to the rotary shaft 255, a rotary arm 262 which is extended from the rotary shaft connector 261, and a slot connector 263 which is inserted to the slot 242 of the hanger rack 240 and rotates the rotary shaft 255 as projected from the end of the rotary arm 262.

0094The rotary shaft connector 261 is disposed at the end of the power transformation unit 260, and is connected to the rotary shaft 255. It is desirable for the rotary arm 262 to be extended through the perpendicular direction with the rotary shaft 255 at the rotary shaft connector 261. The slot connector 263 rotates with fixed radius from the rotary shaft 255 as the rotary shaft 255 rotates. If the rotary arm 262 is disposed perpendicular to the rotary shaft 255, the fixed radius would be the length of the rotary arm 262.

0095It is desirable for the slot 242 to be disposed long with the perpendicular direction to the moving direction of the hanger rack 240. As the reciprocating direction of the hanger rack 240 is the right and left direction, it is explained that the slot is disposed long with the back and forth direction to the following. As the slot 242 is disposed long with the back and forth direction, the movement with back and forth direction is counterbalanced by the slot 242 and the hanger rack 240 reciprocates to the right and left direction, when the slot connector 263 rotates the rotary shaft 255 with being inserted into the slot 242 movement.

0096The water may be collected into the slot 242, as the moisture of the humid air in the treating chamber 210 is condensed. Therefore it is desirable for the drain hole (not shown) to be disposed at the slot 242 for the collected water to drain outside the slot 242.

0097It is possible for the hanger rack 240 to include a guide instead of the slot 242. It is possible for the guide to make the hanger rack 240 reciprocate by the pushing and pulling force of the power transformation unit 260, as the guide which is made of the rib or the projection differently with an exemplar embodiment of the present invention.

0098The fan 230 rotates as connecting to the power transmission unit or the power transformation unit 260. According to an exemplary embodiment of the present invention, the fan 230 is connected to the rotary shaft connector 261 of the power transformation 260. But it is possible for the fan 230 to be connected to the rotary shaft 255.

0099<figref idref="f0009">FIG. 10</figref> illustrates a block diagram of the approximate construction of the fabric treating apparatus 200 according to another exemplary embodiment of the present invention. Refer to <figref idref="f0009">FIG. 10</figref>, the fabric treating apparatus 200 may further include the heating unit 220 and a control unit 270 which controls the driving unit 251. The control unit 270 may be embodied so as to control not only the heating unit 220 or the driving unit 251 but also the whole operations of the fabric treating apparatus 200.

0100The control unit 270 may control at least one of the heating unit 220 and the driving unit 251. If the operating command is inputted into an input unit 290, the control unit 270 may control both the heating unit 220 and the driving unit 251 to be operated simultaneously. For example, the heating unit 220 and the driving unit 251 may be controlled to be operated simultaneously by the control unit 270, in case that the amount of the fabric to be treated is large, or the fabrics are soaked, or the fabrics need to be treated rapidly.

0101In the case that the amount of the fabric to be treated is small, or the fabrics get slightly wet, or the power consumption is reduced, or the noise is reduced at night, it may be controlled so that one of the heating unit 220 and the driving unit 251 may be operated. Specially, in the case that the bad smell or the moisture in the treating chamber 210 is removed, the control unit 270 may control for the only driving unit 251 to be operated and for the fan 230 to rotate in order to reduce the power consumption by the heating unit 220. If users input the self cleaning through the input unit 290, the control unit 270 controls for the driving unit 251 to be operated and for the fan 230 to rotate, thus the air inside of the treating chamber 210 may be deodorized or dried.

0102The fabric treating apparatus 200 may further include a humidity sensor (not shown) which measures the humidity of the treating chamber 210. if the humidity of the treating chamber is measured by the humidity sensor, the control unit 270 may control for the one of the heating unit 220 and the driving unit 251 so as to be operated based on the measured results.

0103If the measured value of the humidity sensor is higher than the required value, the control unit 270 controls for both the heating unit 220 and the driving unit 251 to be operated. But if the measured valued of the humidity sensor is lower than the required value, the control unit 270 controls for one of the heating unit or the driving unit 251 to be operated.

0104When the steam is supplied into the treating chamber 210 by the heating unit 220, the control unit 270 may control for the driving unit 251 to be operated. The control unit 270 operates the driving unit 251 so as to rotate the fan 230, in order to prevent the condensed moisture from sticking to the inside of the inner cabinet 212. If the fabrics is left in the treating chamber 210 after supplying the steam to the fabrics, the condensed water can pollute the fabrics as the condensed water drops to the fabrics. It has an effect that the fan prevents the condensed water from being generated.

0105Also, a fabric treating apparatus according to the present invention is possible to improve space utilization of a treating chamber by disposing a driving unit for the upper part of the outside of a treating chamber.Also, a fabric treating apparatus according to the present invention is possible to minimize the install space by reducing the width of the apparatus.
