Description

The present invention relates to a garment processing device that performs treatments such as drying and wrinkle smoothing on garments.

Conventionally, there is known a garment processing device capable of suspending garments in a housing portion, drying the garments with warm air, and smoothing wrinkles of the garments with steam. An example of such a garment processing apparatus is described in, for example, Patent Document 1.

Japanese Unexamined Patent Publication No. 2018-057413

In the above-mentioned clothes processing apparatus, if the contact efficiency between warm air and clothes is poor, the drying efficiency is poor, and it is difficult to improve the drying performance. Therefore, in order to improve the drying performance, it may be required to improve the contact efficiency between the warm air and the clothes.

Further, in the above-mentioned garment processing device, the surface of the garment to which steam is applied is stretched by the weight of the garment to remove wrinkles of the garment, but the garment is further subjected to a force that stretches the surface of the garment. If it can act on, the performance of wrinkle smoothing can be improved.

Therefore, an object of the present invention is to provide a garment processing apparatus capable of enhancing the performance of drying and wrinkle smoothing.

The clothing processing apparatus according to the main aspect of the present invention includes a storage chamber in which clothes are suspended, a hot air supply unit that supplies warm air into the storage chamber, and steam that supplies steam into the storage chamber. It includes a supply unit, an air circulation unit that sucks in air from the accommodation chamber and blows it out into the accommodation chamber, and a dehumidifying unit for dehumidifying the air in the accommodation chamber. Here, the air circulation unit has a circulation fan that blows out air sucked from the intake port from the discharge port, a deflection member that contacts the air blown out from the discharge port and deflects the air, and an air deflection angle. It includes a drive unit that swings the deflection member so as to change.

The circulation fan can be, for example, a cross-flow fan including a fan having runners arranged in a cylindrical shape and having an axial dimension larger than a radial dimension.

According to the above configuration, when the clothes are dried, the warm air is supplied to the accommodation chamber by the warm air supply unit, and at this time, the air circulation unit can be operated. In this case, the air in the containment chamber warmed by the supply of warm air is taken in from the suction port and blown out from the discharge port as warm air. The blown warm air is deflected by the deflecting member and heads for clothing. At this time, since the deflection angle of the warm air changes due to the swing of the deflection member, the warm air comes into contact with the clothes from various directions. As a result, the contact efficiency of the warm air with the clothes is improved, and the clothes are easily dried.

Moreover, the warm air comes into contact with the clothes from various directions, that is, the direction in which the clothes are pushed by the warm air changes, so that the suspended clothes are shaken. As a result, warm air can be distributed to parts that are difficult to reach when the clothing is stationary, such as between the sleeves of the clothing and the body. In addition, dust adhering to clothes can be easily removed.

Further, when the wrinkles of the clothes are smoothed, steam is supplied to the accommodation chamber by the steam supply unit, and at this time, the air circulation unit can be operated. In this case, the air in the accommodation chamber is taken in from the suction port and blown out from the discharge port as wind. The blown wind is deflected by the swinging deflecting member, so that it comes into contact with the clothes from various directions and shakes the clothes. When clothes are swayed while suspended, a force such as centrifugal force is likely to be applied to the clothes. As a result, the surface of the garment to which the steam is applied is easily stretched, so that the wrinkles of the garment are easily stretched. In addition, by shaking the clothes, dust adhering to the clothes can be removed.

Further, when the clothes are dried, the dehumidifying unit can be operated to dehumidify the air in the storage room containing the moisture taken from the clothes, so that the moisture discharged from the clothes processing device to the outside is reduced, and the clothes processing device is used. The humidity around the area is less likely to increase.

Dehumidification is performed from the air by heat exchange with the heat exchanger provided in. In this way, since the air circulation unit can be used for the circulation of air between the accommodation chamber and the circulation air passage, it is not necessary to separately provide a fan or the like for circulation, and the cost can be reduced.

In the garment processing apparatus according to this aspect, the storage chamber may be arranged in a housing. In this case, the dehumidifying unit includes a circulation air passage that circulates air between the dehumidifying unit and the accommodating chamber, a heat exchanger provided in the circulation air passage, and a cooling fan that sends cooling air to the heat exchanger.

The garment processing device is easily installed so that the rear surface of the housing is close to the wall surface of the room. According to the above configuration, when the clothing processing device is installed as described above, air is sucked into the intake port and air is discharged from the exhaust port, so that between the rear surface of the housing and the wall surface of the room. Air flow is likely to occur, and moisture is less likely to be trapped between them, so that dew condensation is less likely to occur on the wall surface.

The garment processing device according to the present embodiment may be configured to further include a discharge port for discharging air in the accommodation chamber. In this case, the discharge port is provided on the top surface of the storage chamber.

According to the above configuration, when the exhaust drying is performed to exhaust the air in the accommodation chamber to the outside of the clothes processing device, the warm air that has deprived the clothes of moisture, that is, the warm air is easily discharged from the accommodation chamber. Clothes are easier to dry.

In the garment processing device according to the present embodiment, the exhaust port for discharging the air in the accommodation chamber, the exhaust duct for guiding the air discharged from the discharge port to the outside of the garment processing device, and the exhaust duct are opened and closed. A configuration may be adopted in which an opening / closing portion is further provided.

According to the above configuration, the exhaust duct can be closed or opened as needed. In particular, when steam is supplied to the accommodation chamber to smooth out the wrinkles of clothes, the exhaust duct can be closed by the opening / closing part, and the leakage of steam to the outside of the clothes processing device can be suppressed. As a result, the accommodation chamber can be easily filled with steam, the effect of smoothing out wrinkles of clothes can be enhanced, and an increase in humidity around the clothes processing device can be suppressed.

In the case of the above configuration, the ozone supply unit for supplying air containing ozone into the accommodation chamber and the air flowing downstream of the opening / closing unit in the exhaust duct are included in the exhaust duct. A configuration may be adopted in which an ozone removing unit for removing ozone is further provided.

With such a configuration, when deodorizing clothes, air containing ozone is supplied to the accommodation chamber by the ozone supply unit, and at this time, the air circulation unit can be operated. In this case, air containing ozone in the containment chamber is taken in from the suction port and blown out from the discharge port as ozone wind. The blown ozone wind comes into contact with clothing from various directions by being deflected by the swinging deflecting member. As a result, the efficiency of ozone wind contact with the clothes is improved, and the clothes are easily deodorized. Further, by shaking the clothes, ozone can be spread to the portion of the clothes that is difficult to spread when the clothes are stationary, and dust adhering to the clothes can be easily removed.

Further, since the ozone removing unit is provided in the exhaust duct, the air from which ozone has been removed by the ozone removing unit can be discharged to the outside of the clothing processing apparatus. Moreover, since the ozone removing section is located downstream of the opening / closing section, it is possible to prevent the ozone removing section from getting wet with steam by closing the opening / closing section when steam is supplied to the containment chamber. , It is possible to prevent the ozone removal performance from being deteriorated by the ozone removal unit.

According to the present invention, it is possible to provide a garment processing apparatus capable of enhancing the performance of drying and wrinkle smoothing.

Both ends of the fan shaft 714 project from both end faces of the fan 711.

The fan 711 is housed in the casing 712, and both ends of the fan shaft 714 are rotatably supported on both side surfaces of the casing 712. The casing 712 is composed of a main body 712a having an opening front surface and a cover 712b covering the front surface of the main body 712a. The casing 712 is provided with a suction port 715 that opens forward on the front side of the fan 711, that is, on the front surface of the cover 712b, and a discharge port 716 that opens upward on the rear side of the fan 711. The suction port 715 opens in a direction along the bottom surface of the storage chamber 200, and its lower end is slightly higher than the bottom surface of the storage chamber 200. The suction port 715 is provided with a plurality of crosspieces 715a running in a grid pattern. The axial dimensions of the suction port 715 and the discharge port 716 are substantially the same as the dimensions of the fan 711. That is, the suction port 715 and the discharge port 716 have a shape long in the axial direction.

In the casing 712, the filter 717 is arranged between the suction port 715 and the fan 711. The filter 717 collects dust sucked from the suction port 715 together with air.

The right end of the fan shaft 714 penetrates the right side of the casing 712 and further penetrates the right side of the containment chamber 200. On the right side surface of the accommodation chamber 200, a portion corresponding to the air circulation unit 700 is recessed inward, and a fan motor 713 is attached to the outside of the portion. The fan shaft 714 penetrating the right side surface of the accommodation chamber 200 is connected to a rotor (not shown) of the fan motor 713.

The fan motor 713 rotates and drives the fan 711 via the fan shaft 714. When the fan 711 rotates, air is sucked from the suction port 715, and the sucked air is sent by the fan 711 and blown out from the discharge port 716.

The louver mechanism 720 includes a louver 721 and a louver motor 722. The louver 721 corresponds to the deflection member of the present invention, and the louver motor 722 corresponds to the drive unit of the present invention.

Eaves 723 are provided at both left and right ends of the louver 721, and louver shafts 724 are provided at the lower ends of the eaves 723. The circulation fan 710 is provided with support portions 718 at the rear upper ends of both side surfaces of the casing 712. The louver shafts 724 on both sides of the louver 721 are rotatably supported by the support portions 718 on both sides of the casing 712. As a result, the louver 721 is positioned above the discharge port 716 and can swing in the vertical direction.

The right end of the louver shaft 724 penetrates the right support 718 and further penetrates the right surface of the containment chamber 200. A louver motor 722 is mounted above the fan motor 713 on the outside of the right side surface of the accommodation chamber 200. The louver shaft 724 penetrating the right side surface of the accommodation chamber 200 is connected to a rotor (not shown) of the louver motor 722.

The louver motor 722 swings the louver 721 via the louver shaft 724 by rotating forward and reverse by a predetermined rotation angle. The air blown upward from the discharge port 716 of the circulation fan 710 comes into contact with the louver 721 and is deflected. The deflection angle of the air changes according to the angle of the louver 721 that swings, and the direction of the air, that is, the wind, changes.

The fan shaft 714 of the circulation fan 710 serves as a rotation shaft when the fan 711 rotates, and the louver shaft 724 of the louver mechanism 720 serves as a swing shaft when the louver 721 swings. As shown in FIG. 8, in the circulation fan 710, that is, the air circulation unit 700, the rotation axis of the fan 711 and the swing axis of the louver 721 are suspended in the left-right direction, that is, by the pole 261 of the hanger stand 260. It is arranged at the bottom of the storage chamber 200 so as to be parallel to or substantially parallel to the front-back direction of the clothes. In other words, in the pole 261 of the hanger stand 260, the front-rear direction of the clothes hung on the pole 261 is parallel to or substantially parallel to the axial direction of the rotation axis of the fan 711 of the air circulation unit 700 and the swing axis of the louver 721. The garment is held in the upper part of the containment chamber 200 so as to be in a state. At this time, in the circulation fan 710, the center of the rotation axis of the fan 711 in the axial direction substantially coincides with the center of the pole 261.

A dehumidifying unit 800 for dehumidifying the air in the accommodation chamber 200 is arranged between the rear surface of the accommodation chamber 200 and the rear surface of the housing 100.

The dehumidifying unit 800 includes a circulation air passage 810 that circulates air between the accommodation chamber 200, a heat exchanger 820 provided in the circulation air passage 810, and a cooling fan 830 that sends cooling air to the heat exchanger 820.

That is, the heat exchanger 820 constitutes a part of the circulation air passage 810. On the rear surface of the accommodation chamber 200, an air introduction port 203 for the circulation air passage 810 is formed at a position above the right end portion of the air circulation unit 700, and from the circulation air passage 810 at a position above the introduction port 203. Air outlet 204 is formed. The introduction duct 811 is connected to the introduction port 203, extends rearward from the introduction port 203, then bends and extends upward. The outlet duct 812 is connected to the outlet 204, extends rearward from the outlet 204, then bends and extends downward.

The heat exchanger 820 includes a plurality of heat transfer tubes 821 arranged in the left-right direction at predetermined intervals. Each heat transfer tube 821 is flat in the left-right direction and extends in the up-down direction. In the heat exchanger 820, a lower connecting plate 822 and an upper connecting plate 823 are formed at the lower end and the upper end of the plurality of heat transfer tubes 821, respectively. The lower connection plate 822 and the upper connection plate 823 are formed with connection ports 824 and 825 having openings 824a and 825a connected to the heat transfer tubes 821, respectively. The lead-out duct 812 is connected. Further, in the heat exchanger 820, a left side surface plate 826 and a right side surface plate 827 that cover the left and right sides of the plurality of heat transfer tubes 821, respectively, are formed between the lower connection plate 822 and the upper connection plate 823. By surrounding the plurality of heat transfer tubes 821 with the lower connection plate 822, the upper connection plate 823, the left side surface plate 826, and the right side surface plate 827, a cooling air passage 828 in which the plurality of heat transfer tubes 821 are housed is formed.

The cooling fan 830 is a centrifugal fan, and includes a fan 832 and a motor 833 that rotates the fan 832 in the casing 831. The casing 831 is provided with a suction port 834 on the side surface and a discharge port 835 on the peripheral surface. As the cooling fan 830, a fan other than the centrifugal fan, for example, an axial fan may be used.

One end of the cooling duct 840 has a shape corresponding to the discharge port 835 of the cooling fan 830, and the other end is connected to the discharge port 835, and the other end has a shape corresponding to the inlet of the cooling air passage 828 of the heat exchanger 820.

In the dehumidifying unit 800, the introduction duct 811 and the outlet duct 812 and the cooling duct 840 are made of a resin material, and the heat exchanger 820 is also made of a resin material. By forming the heat exchanger 820 from the resin material in this way, the weight of the dehumidifying unit 800 can be reduced.

The hood 280 corresponds to the air guide portion of the present invention.

FIG. 10 is a block diagram showing the configuration of the garment processing device 1.

In addition to the above configuration, the garment processing device 1 includes an operation unit 901 and a control unit 902.

The operation unit 901 includes operation buttons such as a selection button for selecting an operation course and a start button for starting operation, and outputs an operation signal corresponding to the operation button operated by the user to the control unit 902.

The control unit 902 includes a microcomputer, various driver circuits, and the like, and includes an ozone generator 320, a heater 330, a blower fan 340 and an intake damper 360 of the first supply unit 300, a pump 461 and a heater 472 of the second supply unit 400. , The exhaust damper 620 of the exhaust unit 600, the fan motor 713 and the louver motor 722 of the air circulation unit 700, the cooling fan 830 of the dehumidifying unit 800, and the like are controlled.

In the clothes processing apparatus 1 of the present embodiment, it is possible to perform a deodorizing / sterilizing operation for deodorizing / sterilizing clothes, a drying operation for drying clothes, and a wrinkle smoothing operation for smoothing wrinkles of clothes.

FIG. 11 is a flowchart showing the operation control of the garment processing device 1.

When the operation to start the operation is performed, the control unit 902 determines which operation is selected from the deodorizing / sterilizing operation, the drying operation, and the wrinkle smoothing operation (S1).

When the deodorizing / sterilizing operation is selected (S1: deodorizing / sterilizing), the deodorizing / sterilizing operation is started, and the control unit 902 executes the deodorizing / sterilizing step (S2). In the deodorizing / sterilizing step, the control unit 902 operates the blower fan 340 and the ozone generator 320 in the first supply unit 300. Before the start of operation, that is, when the garment processing device 1 is in the stopped state, the opening / closing plate 361 of the intake damper 360 is in the first closed position, and the opening / closing plate 621 of the exhaust damper 620 is in the open position. The control unit 902 does not operate the intake damper 360 and the exhaust damper 620, and maintains a state in which the opening / closing plate 361 is in the first closed position and the opening / closing plate 621 is in the open position.

As shown by the solid line arrow in FIG. 5, by the operation of the blower fan 340, the air outside the machine is taken into the intake duct 350 from the front intake port 101 and sent into the first supply duct 310.

As shown in FIG. 2, the air flowing in the first supply duct 310 passes through the ozone generator 320, and at this time, the ozone generated by the ozone generator 320 is mixed into the air. In this way, the air containing ozone passes through the first supply duct 310 to reach the first supply port 210, and is discharged from the first supply port 210 into the accommodation chamber 200. The discharged ozone-containing air hits the cover 240 and spreads to the surroundings, a part of the air is discharged from the plurality of discharge holes 244, and the rest 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 by the cover 240 toward the upper garment and is widely applied to the garment. Clothes are deodorized and sterilized by the deodorizing and sterilizing action of ozone.

As shown in FIGS. 6A and 6B, the air whose ozone concentration has decreased due to the deodorization and sterilization of clothes is discharged into the exhaust duct 610 from the exhaust port 202 provided on the top surface of the storage chamber 200. , Flows through the exhaust duct 610 and is discharged to the outside of the machine from the exhaust port 104. The air flowing in the exhaust duct 610 passes through the ozone removal filter 630. As a result, ozone in the air is removed, and the air whose ozone concentration has been lowered to an appropriate level is discharged to the outside of the machine.

Further, in the deodorizing / sterilizing step, the control unit 902 drives the fan motor 713 to operate the circulation fan 710 in the air circulation unit 700, and drives the louver motor 722 to swing the louver 721 in the vertical direction. Let me. At this time, the louver 721 may swing continuously, or may be stopped for a predetermined time every time it swings once or several times.

As shown in FIG. 7A, the air containing ozone in the storage chamber 200 is taken into the casing 712 from the suction port 715 and blown out from the discharge port 716 as ozone wind. The blown ozone wind is deflected by the louver 721 and heads toward clothing. At this time, since the deflection angle of the ozone wind changes due to the louver 721 swinging, the ozone wind comes into contact with the clothes from various directions. As a result, the efficiency of ozone wind contact with clothing is improved, and clothing is easily deodorized and sterilized. In addition, the suspended clothing is shaken by pushing the clothing with ozone wind from various directions. As a result, ozone can be distributed to parts that are difficult to distribute when the clothing is stationary, such as between the sleeves of the clothing and the body. In addition, dust adhering to clothes can be easily removed.

Further, the clothes are hung on the pole 261 of the hanger stand 260 so that the front-rear direction thereof is parallel to the axial direction of the swing axis of the louver 721 of the air circulation unit 700. Therefore, even when a plurality of clothes are housed in the storage chamber 200 as shown in FIG. 7A, the ozone wind discharged from the circulation fan 710 and deflected by the louver 721 is generated between the clothes and the clothes. It will be easier to reach the upper part of the containment chamber 200 through the space. This makes it easier for the ozone wind to hit a plurality of clothes evenly, and the plurality of clothes are well deodorized and sterilized.

When the predetermined deodorizing / sterilizing time has elapsed, the control unit 902 stops the operations of the ozone generator 320, the blower fan 340, the circulation fan 710, and the louver 721, and ends the deodorizing / sterilizing step. In this way, the deodorizing / sterilizing operation is completed.

Next, in step S1, the control unit 902 starts the drying operation when it determines that the drying operation is selected (S1: drying). First, the control unit 902 executes a circulation drying step (S3). In the circulation drying step, the control unit 902 operates the intake damper 360 to switch the opening / closing plate 361 from the first closed position to the second closed position. Further, the control unit 902 operates the exhaust damper 620 to switch the opening / closing plate 621 from the open position to the closed position. Next, the control unit 902 operates the blower fan 340 and the heater 330 in the first supply unit 300.

As shown by the broken line arrow in FIG. 5, by the operation of the blower fan 340, the air in the accommodation chamber 200 is taken into the intake duct 350 from the bottom air intake port 250 and sent into the first supply duct 310.

As shown in FIG. 2, the air flowing in the first supply duct 310 is heated by the heater 330 and becomes warm air at a temperature suitable for drying (for example, about 60 ° C.). After that, the warm air reaches the first supply port 210 and is discharged from the first supply port 210 into the accommodation chamber 200. The discharged warm air is diffused by the cover 240 and directed to the clothing above, and is widely applied to the clothing, like the air containing ozone. This causes the clothes to dry.

In the circulation drying step, the exhaust duct 610 is closed by the exhaust damper 620. Therefore, the air in the accommodation chamber 200 is not discharged from the discharge port 202 and is not discharged to the outside of the housing 100. Air circulates between the containment chamber 200 and the intake duct 350, the blower fan 340 and the first supply duct 310. Since the temperature of the air taken into the first supply duct 310 gradually rises, the output of the heater 330 is lowered accordingly. As a result, the temperature of the air discharged into the accommodation chamber 200 is maintained at an appropriate temperature.

In the circulation drying step, the control unit 902 operates the circulation fan 710 in the air circulation unit 700 and swings the louver 721 in the vertical direction. Further, the control unit 902 operates the cooling fan 830 of the dehumidifying unit 800.

As shown in FIG. 7A, the air in the accommodation chamber 200 warmed by the supply of warm air is taken into the casing 712 from the suction port 715 and blown out from the discharge port 716 as warm air. The blown warm air is deflected by the oscillating louver 721 and comes into contact with clothing from various directions. As a result, the contact efficiency of the warm air with the clothes is improved, and the clothes are easily dried. Further, by shaking the clothes, warm air can be spread to the portion of the clothes that is difficult to spread when the clothes are stationary, and dust adhering to the clothes can be easily removed.

Further, as in the case of the deodorizing / sterilizing operation, even when a plurality of clothes are housed in the storage chamber 200 as shown in FIG. 7A, the clothes are discharged from the circulation fan 710 and deflected by the louver 721. The warm air can easily reach the upper part of the storage chamber 200 through the clothes. As a result, the warm air can easily hit the plurality of clothes evenly, and the plurality of clothes can be easily dried.

The air taken in by the circulation fan 710 contains moisture deprived of clothing. As shown by the alternate long and short dash arrow in FIG. 7A, the air blown out from the circulation fan 710, that is, the right end portion of the air circulation unit 700 is received by the hood 280 and introduced into the circulation air passage 810 through the introduction port 203. .. The introduced air flows through the circulation air passage 810 and is led out into the accommodation chamber 200 from the outlet 204. Further, as shown in FIG. 9B, by the operation of the cooling fan 830, the air outside the machine is taken in from the intake port 105 as cooling air and sent to the heat exchanger 820 to cool the heat exchanger 820. After passing through the air passage 828, the air is discharged to the outside of the machine through the exhaust port 106.

When the air flowing through the circulation air passage 810 passes through the plurality of heat transfer tubes 821 of the heat exchanger 820, it is cooled and dehumidified by exchanging heat with the cooling air flowing through the cooling air passage 828. The water discharged from the air is drained from the drain port 813 of the introduction duct 811 and finally stored in the drain tank 480 of the second supply unit 400.

In this way, the dehumidifying unit 800 dehumidifies the air in the storage chamber 200. As a result, the increase in the moisture contained in the warm air before being applied to the clothes is suppressed, so that the clothes are easily dried.

In the circulation drying step, although dehumidification is performed by the dehumidifying unit 800 as described above, air is discharged from the inside of the accommodation chamber 200, and new air is taken into the first supply duct 310 from the outside of the machine to become warm air and becomes the accommodation chamber. Compared to the case where the so-called exhaust type drying supplied in the 200 is performed, the amount of moisture contained in the warm air increases, and it becomes difficult to remove the moisture from the clothes. Therefore, the clothes hung on the hanger stand 260 are slowly dried while being shaken by the warm air, so that the clothes are easily wrinkled and wrinkled as they are dried.

When the predetermined time elapses and the clothes in the storage chamber 200 become dry to some extent, the control unit 902 stops the heater 330, the blower fan 340, and the cooling fan 830, and ends the circulation drying step.

Next, the control unit 902 executes the exhaust drying step (S4). In the exhaust drying step, the control unit 902 operates the intake damper 360 to switch the opening / closing plate 361 from the second closed position to the first closed position. Further, the control unit 902 operates the exhaust damper 620 to switch the opening / closing plate 621 from the closed position to the open position. Then, the control unit 902 operates the blower fan 340 and the heater 330. The air circulation unit 700, that is, the circulation fan 710 and the louver 721 are operating following the circulation drying step.

As shown by the solid line arrow in FIG. 5, by the operation of the blower fan 340, external air is taken into the intake duct 350 from the front intake port 101 and sent into the first supply duct 310. Hot air is generated in the first supply duct 310 by heating the heater 330, and is discharged from the first supply port 210 into the accommodation chamber 200. The discharged warm air and the warm air circulating in the storage chamber 200 by the air circulation unit 700 are applied to the clothes, and the clothes are dried. The warm air that has deprived the clothes of water is discharged to the outside of the machine through the exhaust port 202 and the exhaust duct 610.

When a predetermined time has elapsed from the start of the exhaust drying process, the control unit 902 stops the operations of the heater 330, the blower fan 340, the circulation fan 710, and the louver 721, and ends the circulation drying process. In this way, the drying operation is completed.

As described above, in the drying operation, the circulation drying step is performed before the exhaust drying step, and in this circulation drying step, the air in the accommodation chamber 200 is dehumidified by the dehumidifying unit 800. As a result, in the drying operation, the humidity discharged from the clothes processing device 1 to the outside is reduced, so that the humidity around the clothes processing device 1 is less likely to increase.

In the exhaust drying step, the cooling fan 830 may be operated to dehumidify the air in the storage chamber 200 by the dehumidifying unit 800. As a result, the humidity discharged from the garment processing device 1 to the outside can be further reduced.

Next, in step S1, when the control unit 902 determines that the wrinkle smoothing operation is selected (S1: wrinkle smoothing), the control unit 902 starts the wrinkle smoothing operation and executes the preparatory step (S5). In the preparatory step, the control unit 902 operates the heater 472 of the steam generator 470 while the pump 461 is stopped in the second supply unit 400. As a result, the temperature of the main body 471 of the steam generator 470 rises.

Further, in the preparation step, the control unit 902 operates the circulation fan 710 in the air circulation unit 700 and swings the louver 721 in the vertical direction. As shown in FIG. 7A, the air in the accommodation chamber 200 is taken into the casing 712 from the suction port 715 and blown out from the discharge port 716 as wind. The blown wind is deflected by the oscillating louver 721, so that it comes into contact with the clothes from various directions and shakes the clothes. This makes it easier for dust to fall from the clothes.

When the main body 471 of the steam generator 470 becomes sufficiently hot, the control unit 902 ends the preparation step and executes the steam step (S6). In the steam process, the control unit 902 operates the exhaust damper 620 to switch the opening / closing plate 621 from the open position to the closed position. As a result, the exhaust duct 610 is closed. Next, the control unit 902 operates the pump 461 while the heater 472 is continuously operated. As shown in FIG. 3, high-temperature steam is generated in the steam generator 470 and discharged into the second supply duct 410. The released steam rises in the second supply duct 410 to reach the second supply port 220, and is discharged from the second supply port 220 into the accommodation chamber 200. The discharged steam hits the cover 240 and spreads to the surroundings, a part of the steam is discharged from the plurality of discharge holes 244, and the rest is discharged from between the cover 240 and the bottom surface of the storage chamber 200. In this way, the steam is diffused by the cover 240 toward the upper garment and is widely applied to the garment. The moisture and heat of steam smoothes the wrinkles of clothing.

When steam flows through the second supply duct 410, a part of it may condense to form condensed water. Condensed water flows downward, collects in the water storage unit 413, and is discharged from the discharge port 414. The discharged condensed water is collected in the drainage tank 480 through the drainage hose 490. As described above, in the present embodiment, since the water storage unit 413 for collecting the dew condensation water is provided below the introduction port 412 of the second supply duct 410, the dew condensation water is collected from the introduction port 412 to the steam generator 470. It is prevented from flowing into the inside of.

Further, in the steam process, the circulation fan 710 and the louver 721 continue to operate. The clothes are shaken by the wind blown out from the discharge port 716 and deflected by the louver 721. When clothes are swayed while suspended, a force such as centrifugal force is likely to be applied to the clothes. As a result, the surface of the garment to which the steam is applied is easily stretched, so that the wrinkles of the garment are easily stretched. In addition, since the clothes are wet with steam, the dust adhering to the clothes can be removed by shaking the clothes, although it is not as dry as in the preparatory process.

Further, as in the case of the deodorizing / sterilizing operation, even when a plurality of clothes are housed in the storage chamber 200 as shown in FIG. 7A, the clothes are discharged from the circulation fan 710 and deflected by the louver 721. The wind easily passes between clothes and reaches the upper part of the containment chamber 200. As a result, the wind easily hits the plurality of clothes evenly, the plurality of clothes are shaken well, and the wrinkles are easily stretched.

During the steaming process, the exhaust duct 610 is in the closed state. Therefore, it is prevented that the steam in the accommodation chamber 200 is discharged to the outside of the machine through the exhaust duct 610. Further, since the ozone removal filter 630 is provided downstream of the exhaust damper 620 in the exhaust duct 610, it is possible to prevent the ozone removal filter 630 from being severely wetted by steam contacting the ozone removal filter 630. ..

When the predetermined steam supply time has elapsed, the control unit 902 stops the heater 472 and the pump 461 to end the steam process.

Next, the control unit 902 sequentially executes the circulation drying step and the exhaust drying step (S7, S8). The circulation drying step and the exhaust drying step are the same as the circulation drying step and the exhaust drying step in the drying operation. The circulation drying process and the exhaust drying process dry the clothes moistened by steam. The time of the circulation drying step and the exhaust drying step in the wrinkle smoothing operation may be suitable for the wrinkle smoothing operation and may be different from the time of the drying operation. Further, in the circulation drying step, since the exhaust damper 620 is already in the closed position, only the intake damper 360 operates, and the opening / closing plate 361 is switched from the first closed position to the second closed position.

When the exhaust drying step is completed, the control unit 902 executes the ventilation step (S9). That is, the control unit 902 keeps the circulation fan 710 and the louver 721 operating following the exhaust drying step. The air in the accommodation chamber 200 is taken in from the suction port 715 and blown out from the discharge port 716 into the accommodation chamber 200, so that the air outside the machine is brought into the first supply unit 300 through the intake duct 350 and the first supply duct 310. 1 It is taken into the accommodation chamber 200 from the supply port 210, and the air in the accommodation chamber 200 is discharged to the outside of the machine through the exhaust port 202 and the exhaust duct 610. As a result, the inside of the accommodation chamber 200 is ventilated, and the inner wall and the like in the accommodation chamber 200 are dried even if they are moistened by steam.

When the predetermined ventilation time elapses, the control unit 902 stops the operation of the circulation fan 710 and the louver 721, and ends the ventilation process. In this way, the wrinkle smoothing operation is completed.

As described above, in the wrinkle smoothing operation, in the steam process, the exhaust duct 610 is closed by the exhaust damper 620 to prevent steam from being discharged from the inside of the accommodation chamber 200 to the outside of the machine. Further, a circulation drying step is performed before the exhaust drying step, and in this circulation drying step, the air in the storage chamber 200 is dehumidified by the dehumidifying unit 800. As a result, in the wrinkle smoothing operation, the humidity discharged from the clothes processing device 1 to the outside is reduced, so that the humidity around the clothes processing device 1 is less likely to increase.

In addition to the deodorizing / sterilizing operation, the drying operation, and the wrinkle smoothing operation, the clothes processing apparatus 1 may perform, for example, a drying / deodorizing / sterilizing operation in which deodorization / sterilization is performed following drying.

Further, in addition to the exhaust type deodorizing / sterilizing operation described above, as a circulation type deodorizing / sterilizing operation, the intake damper 360 is set to the second closed position and the exhaust damper 620 is set to the closed position as in the circulation drying step. The operation may be performed so as to operate the ozone generator 320 while circulating air between the accommodation chamber 200, the intake duct 350, the blower fan 340, and the first supply duct 310. In this circulation type deodorizing / sterilizing operation, the ozone concentration in the air increases while the air is circulating, so that high-concentration ozone can act on clothes, and a high deodorizing / sterilizing effect can be expected. .. Further, in this deodorizing / sterilizing operation, not only the exhaust duct 610 is closed by the exhaust damper 620, but also the front intake port 101 is closed by the intake damper 360, so that the concentration is high. It is possible to prevent ozone from leaking out of the machine.

Further, the exhaust damper 620 may be configured not only to be switched to an open position where the opening / closing plate 621 is completely opened, but also to be able to stop at a plurality of opening angles when the opening / closing plate 621 is opened. By changing the opening angle of the opening / closing plate 621, the opening amount of the communication port 611 of the exhaust duct 610 changes, and the amount of air exhausted from the inside of the accommodation chamber 200 changes. In this case, in the exhaust drying step of the drying operation and the wrinkle smoothing operation, the opening angle of the opening / closing plate 621 is gradually increased with the passage of time, and the amount of air discharged from the accommodating chamber 200 is increased. In this way, the humidity in the storage chamber 200 is gradually lowered, so that the wrinkle smoothing effect can be exhibited even in the exhaust drying step.

Further, a temperature sensor and a humidity sensor may be arranged in the accommodation chamber 200. In this case, the cycle drying step may be switched to the exhaust drying step, or the exhaust drying step may be terminated, based on the temperature and humidity in the storage chamber 200. Further, in the exhaust drying step, the opening angle of the opening / closing plate 621 may be gradually increased according to the degree of change in the temperature and humidity in the accommodation chamber 200.

Further, in the steam process, there is a possibility that a small amount of steam leaks from the front intake port 101. Therefore, in order to prevent such steam leakage, in the steam process, the opening / closing plate 361 of the intake damper 360 is switched to the second closed position, and the outlet 351a of the first duct 351, that is, the front intake port 101 is closed. You may do so.

Ozone air can be brought into contact with the clothing from various directions. As a result, the efficiency of ozone wind contact with clothing is improved, and clothing is easily deodorized and sterilized. Further, since the clothes are shaken by the ozone wind from various directions, ozone can be spread to the part of the clothes that is difficult to spread when the clothes are stationary, and the dust adhering to the clothes can be easily removed.

Further, according to the present embodiment, since the ozone removal filter 630 is provided in the exhaust duct 610, the air from which ozone has been removed by the ozone removal filter 630 can be discharged to the outside of the machine. Moreover, since the ozone removal filter 630 is arranged downstream of the exhaust damper 620, the exhaust damper 620 is blocked when steam is supplied into the storage chamber 200, so that the ozone removal filter 630 is caused by steam. It is possible to prevent it from getting wet, and it is possible to prevent the ozone removal performance from being deteriorated by the ozone removal filter 630.
