The lower end portion of the pin 682 is set to have an outer diameter larger than the outer diameter of the other parts to form a flange portion 682 a, and a coil spring 683 is arranged between the flange portion 682 a and the boss 673. The coil spring 683 is in a compressed state, and the pin 682 is pushed downward by the coil spring 683. As shown by the broken line in FIG. 7, the on-off valve 681 blocks the outflow port 672. When the pin 682 moves upward against the urging force of the coil spring 683, the on-off valve 681 leaves the outflow port 672, and the outflow port 672 opens.

It should be noted that the outflow port 672 and the on-off valve 681 are the outflow port 441 and the on-off valve 442 shown in FIG. 3, respectively.

When the water supply tank 600 is used as a spray device, the operation part 641 is pressed downward with a finger. At this time, the rotation stop portion 641b of the operation portion 641 is guided by the left and right inner walls of the recess 611. Thereby, the operation part 641 is prevented from rotating to the left and right, and the spray port 645a is prevented from swinging to the left and right.

When the operation portion 641 is pressed downward, the piston 646 moves downward in the pump portion 650, and the pressure in the pump portion 650 rises. At this time, the check valve 653 of the water suction port 652 is closed, and the check valve 647 of the discharge pipe 643 is opened. As a result, the water stored in the pump unit 650 flows to the discharge pipe 643 and is sprayed from the spray port 645 a of the nozzle unit 645. The sprayed water passes through the spray window 644 and spreads toward the rear as shown by the one-dot chain line in FIG. 6. Since the left and right inner walls of the recessed portion 611 expand toward the rear, it is not easy to hinder the diffusion of water.

When the force pressing the operating portion 641 downward is released, the piston 646 rises due to the force of the coil spring 651, and the pressure in the pump portion 650 drops to be in a negative pressure state. At this time, the check valve 653 of the water suction port 652 is opened, and the check valve 647 of the discharge pipe 643 is closed. Thereby, the water in the tank main body 610 is sucked by the water suction pipe 660 and stored in the pump part 650.

It should be noted that when the operation portion 641 is first pressed, there is no water in the pump portion 650, and therefore, the air in the pump portion 650 is ejected from the spray port 645a.

(A) and (b) of FIG. 8 are side sectional views of the main part of the clothes processing apparatus 1 in the state where the box 700 is accommodated in the box 100, and the state where the box 700 is pulled out from the box 100, respectively.

The water supply box 600 (440) is contained in the box 700. Furthermore, a drain tank 480 is also accommodated in the box 700 next to the water supply tank 600. The box 700 corresponds to the arrangement part of the present invention.

The box 700 has a substantially rectangular parallelepiped shape with an open upper surface. On the bottom surface of the box 700, arms 701 with rotating shafts 701a at the top ends are provided on the left and right sides. In the case 100, a bearing 104 corresponding to each arm 701 is provided at the front end of the bottom surface. The rotation shaft 701a of each arm 701 is inserted into the hole of the boss 104a of the bearing portion 104, whereby the box 700 can be rotated in the forward and backward directions. The user can move the box 700 between the storage position stored in the box 100 shown in FIG. 8(a) and the pulled-out position shown in FIG. 8(b) where it is pulled out from the box 100. When storing and pulling out, the box 700 passes through the entrance 102 of the box 100.

An opening 702 is formed on the bottom surface of the box 700, and when the water supply box 600 is housed in the box 700, the outflow port 630 protrudes downward from the opening 702.

As shown in FIG. 8(a), when the box 700 containing the water supply tank 600 and the drain tank 480 is stored in the box body 100, the water supply tank 600 is set at the water supply position, and the outlet portion 630 is inserted into the water supply tank 450 . At the bottom of the water supply tank 450, a protrusion 453 is provided at a position where the outlet portion 630 is inserted. The pin 682 of the outflow port 630 hits the protrusion 453 and is pushed up, the on-off valve 681 leaves the outflow port 672, and the outflow port 672 is opened. As a result, the water flows out from the water supply tank 600 and is stored in the water supply tank 450.

As shown in Figure 8(b), when the box 700 is pulled out of the box body 100, the opening on the upper surface of the box 700 opens outward, so the water supply box 600 and the drain box can be taken out from the box 700 480. At this time, in the outflow port 630 of the water supply tank 600, the outflow port 672 is in a state closed by the on-off valve 681, so water does not leak from the water supply tank 600.

The user can take out the water supply box 600 from the box 700, remove the outlet portion 630 from the box main body 610, and replenish water into the box main body 610, that is, the water supply box 600 through the inlet/outlet portion 613. In addition, the user can take out the drain tank 480 from the box 700 and discard the water in the drain tank 480.

Furthermore, the user can use the water supply tank 600 as a spray device. In the state where the water supply tank 600 is housed in the box 700, the head 640 of the spray mechanism 620 is located on the front side, and the spray port 645a faces the rear. The user takes the water supply box 600 out of the box 700, directly holds the front side of the water supply box 600, and extends a finger from the front side to the operation portion 641 to press the operation portion 641. As a result, water is sprayed from spray port 645a.

The clothes treating apparatus 1 of the present embodiment can perform a deodorizing and sterilizing operation to deodorize and sterilize clothes, a drying operation to dry the clothes, and a wrinkle smoothing operation to smooth out the wrinkles of the clothes.

During the deodorization and sterilization operation, the blower fan 340 and the ozone generator 320 in the first supply unit 300 operate. As shown in FIG. 5, external air is taken into the suction duct 350 from the suction port 101, and the ozone contained in the air is removed by the ozone removing filter 360 in the filter housing 351. The ozone-removed air is sent into the first supply duct 310 by the blower fan 340.

As shown in FIG. 2, the air flowing in the first supply pipe 310 passes through the ozone generator 320, and at this time, the ozone generated in the ozone generator 320 is mixed into the air. In this way, the air containing ozone passes through the first supply duct 310, reaches the first supply port 210, and is discharged from the first supply port 210 into the storage room 200. The discharged ozone-containing air hits the cover 240 and spreads around, a part of the air is discharged from the plurality of discharge holes 244, and the remaining part of the air is discharged from between the cover 240 and the bottom surface of the storage chamber 200. In this way, the air containing ozone is diffused through the cover 240 and then travels to the upper clothing, and comes into contact with the clothing over a large area. Clothing is deodorized and sterilized by the deodorization and sterilization effect of ozone.

The air whose concentration has been reduced due to the deodorization and sterilization of clothes passes through the ozone removal filter 271 and the exhaust port 202 of the exhaust filter unit 270 provided in the upper part of the storage chamber 200 and is discharged to the outside of the cabinet 100. The ozone removal filter 271 removes ozone contained in the air.

During the drying operation, the blowing fan 340 and the heater 330 in the first supply unit 300 operate. As shown in FIG. 2, the air taken in by the blower fan 340 and flowing in the first supply duct 310 is heated by the heater 330 to become warm air of a temperature suitable for drying (for example, about 60° C.). Then, the warm air reaches the first supply port 210 and is discharged into the storage room 200 from the first supply port 210. The discharged warm air is diffused by the cover 240 like the air containing ozone, and then travels to the upper clothing, and comes into contact with the clothing over a large area. As a result, the laundry is dried. The warm air after the moisture is peeled from the clothes is exhausted to the outside through the exhaust port 202.

In the wrinkle smoothing operation, first, in the second supply unit 400, the steam generator 470, that is, the heater 472 and the pump 461 are operated. As shown in FIG. 3, high-temperature steam is generated in the steam generator 470 and discharged into the second supply pipe 410. The released steam rises in the second supply pipe 410 to reach the second supply port 220, and is discharged into the storage chamber 200 from the second supply port 220. The discharged steam hits the cover 240 and spreads around, a part of which is discharged from the plurality of discharge holes 244, and the remaining part is discharged from between the cover 240 and the bottom surface of the storage chamber 200. In this way, the steam is diffused through the cover 240 and travels to the upper clothes, and comes into contact with the clothes in a large area. With the moisture and heat of the steam, the wrinkles of the clothes are smoothed.

When the steam flows in the second supply pipe 410, a part of the steam may condense and produce dew condensation water. The dew condensation water flows downward and is stored in the water storage part 413, and is discharged from the discharge port 414. The drained dew condensation water is recovered into the drain tank 480 through the drain hose 490. In this way, in this embodiment, since the water storage portion 413 for storing dew condensation water is provided below the inlet 412 of the second supply pipe 410, it is possible to prevent the dew condensation water from flowing from the inlet 412 to the inside of the steam generator 470. .

After steam is supplied to the clothes in the storage room 200 for a predetermined time, the heater 472 and the pump 461 are stopped. Then, in the first supply unit 300, the blower fan 340 and the heater 330 operate, and the warm air comes into contact with the clothes in the same manner as the drying operation. In this way, the clothes wetted by the steam are dried.

It should be noted that, in the laundry treatment device 1, in addition to the deodorization and sterilization operation, the drying operation, and the wrinkle smoothing operation, for example, drying, deodorization, and sterilization may be performed after drying. Running.

As described above, according to the present embodiment, since the box 700 is provided with the water supply box 600 that constitutes the spray device, the user can use the water supply box 600 arranged in the box 700 as a spray device to smooth the wrinkles before the operation. The clothes can be sprayed conveniently.

Furthermore, since the water supply tank 600 has the function of a spray device, it is not necessary to additionally prepare a spray device for spraying work.

Furthermore, since the length of the water suction pipe 660 of the spray mechanism 620 is set to the length of water required for one wrinkle smoothing operation when the front end of the water suction pipe 660 cannot reach the water surface of the tank main body 610, It is prevented that the wrinkle smoothing operation cannot be performed when the water in the water supply tank 600 is excessively used during the spraying operation and the water has not been replenished.

Furthermore, since the water supply tank 600 adopts a structure in which the tank main body 610 has a recess 611 and the head 640 of the spray mechanism 620 is housed in the recess 611, the tank can be enlarged by the portion of the tank main body 610 existing around the head 640. The volume of the main body 610. Furthermore, since the front surface of the spray port 645a of the spray mechanism 620 of the recess 611 is open, the water sprayed from the spray port 645a can be discharged from the open portion to the outside of the recess 611. Furthermore, since the head 640 does not protrude from the recess 611, the water supply tank 600 can be placed in an appropriate place with the top surface 610a of the tank main body 610 facing downward.

Furthermore, since the concave portion 611 is provided on the top surface 610a of the tank main body 610, and the head 640 is disposed on the upper part of the water supply tank 600 by being disposed in the concave portion 611, the user can hold the water supply tank 600 taken out from the tank 700 in the upper and lower positions.
