Disclosure of Invention

Problems to be solved by the invention

Accordingly, an object of the present invention is to provide a laundry treating apparatus capable of improving drying and wrinkle smoothing performance.

Means for solving the problems

A laundry treatment apparatus according to a first aspect of the present invention includes: a housing chamber configured in the box body for housing clothes; a holding unit configured to hold the laundry in a state of being suspended in the storage chamber; a warm air supply unit configured to supply warm air into the storage chamber; a steam supply unit configured to supply steam into the accommodating chamber; and an air circulation unit that sucks air in the storage chamber and blows the air out of the storage chamber. Wherein the air circulation part includes: a circulation fan for blowing out the air sucked from the air suction port from the discharge port; a deflecting member that deflects the air blown out from the discharge port by contacting the air; and a driving part swinging the steering member to change a steering angle of the air. Further, the holding portion holds a plurality of clothes in parallel in a front-rear direction of the clothes and in parallel with an axial direction of the swing shaft of the steering member.

For example, the circulation fan may be a cross-flow fan including a fan having an impeller configured in a cylindrical shape and having a dimension in an axial direction larger than a dimension in a radial direction. Further, for example, the holding portion can be configured as follows: has a shape extending parallel to the axial direction of the swing shaft of the turning member, and holds a plurality of clothes side by side in the extending direction.

According to the above configuration, when the clothes are dried, the warm air is supplied into the accommodating 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 storage room warmed by the supply of the warm air is taken in from the intake port and blown out from the discharge port as the warm air. The blown warm air is turned by the turning member and then goes to the clothes. At this time, the steering angle of the warm air is changed by the swinging of the steering member, and therefore the warm air comes into contact with the clothes from various directions. This improves the efficiency of contact between the warm air and the clothes, and the clothes are easily dried.

Also, the warm air comes into contact with the laundry from various directions, that is, the direction in which the warm air blows the laundry is changed, and thus the hung laundry is shaken. This makes it possible to cause warm air to reach portions of the clothing, such as underarm portions, which are difficult to reach when the clothing is stationary. In addition, dust adhering to the clothes becomes easy to fall.

In addition, when the wrinkles of the clothes are smoothed, the steam is supplied to the accommodating chamber through the steam supply part, and the air circulation part can be operated at the time. In this case, the air in the storage chamber is taken in through the intake port and blown out through the discharge port as wind. The blown wind is turned by the swinging turning member, thereby coming into contact with the laundry from various directions, and shaking the laundry. When the laundry is shaken in a suspended state, a force such as a centrifugal force is easily applied to the laundry. Thus, the surface of the laundry hit by the steam is easily smoothed, and thus wrinkles of the laundry are easily flattened. Further, by the laundry being shaken, dust attached to the laundry can be dropped.

Further, since the holding portion holds the plurality of clothes in parallel with the front-rear direction of the clothes and the axial direction of the swing shaft of the turning member, even when the plurality of clothes are stored in the storage chamber, the wind discharged from the circulation fan and turned by the turning member easily passes through between the clothes and the clothes to reach the upper portion of the storage chamber. Accordingly, the wind easily comes into contact with the plurality of clothes in all directions, so that the plurality of clothes are easily dried, and wrinkles of the plurality of clothes are easily smoothed.

In the laundry processing apparatus according to this aspect, the following configuration may be adopted: the air circulation unit is disposed below the holding unit in the storage chamber. In this case, the steering device may further include a cover portion that has a plurality of opening portions through which air that is steered by the steering member passes, and that covers the steering member.

According to the above structure, even if the hung laundry is dropped, the laundry is prevented from pressing on the diverting member so that the diverting member is stopped.

With the above configuration, the steering member can be further swung such that the tip end thereof draws an arc. In this case, a portion of the cover portion that covers the steering member from the radial direction of the arc may have the plurality of opening portions and may be formed in an arc shape.

With this configuration, when the turning member swings, the distances between the tip end of the turning member and the openings are almost equal, and therefore air can be blown out from the openings with almost equal force. Further, when clothes fall on the hood portion, the clothes easily slip off the arc-shaped portion, and the opening portions are not easily clogged with the clothes.

In the laundry processing apparatus according to this aspect, the following configuration may be adopted: the processing apparatus further includes a rack disposed in the accommodation chamber and configured to place the processing object thereon.

According to the above configuration, the object to be processed, which is not easily hung by the holding portion, can be placed on the rack and dried.

In the case of adopting the above structure, further, the carrier may adopt a foldable structure. In this case, a fixing portion for fixing the rack to be deformable to an unset state in which the rack is folded and erected along the wall surface and a set state in which the rack is unfolded and laid down to the front of the wall surface may be provided on any one of the rear surface, the right side surface, and the left side surface of the housing chamber.

With this configuration, when the rack is not used, the hung clothes are not easily obstructed by setting the rack to the non-set state. In addition, when the carrier is used, the carrier can be easily deformed into the set state by grasping the tip side of the folded carrier and unfolding the carrier while laying it down.

A laundry treatment apparatus according to a second aspect of the present invention includes: a storage chamber configured in the box body for storing clothes; a holding unit configured to hold the laundry in a state of being suspended in the storage chamber; a steam supply unit configured to supply steam into the accommodating chamber; and an air circulation unit that sucks air in the storage chamber and blows the air out of the storage chamber, and the blown air is directed to the hung clothes. Wherein the air circulation part includes: a circulation fan for blowing out the air sucked from the air suction port from the discharge port; a deflecting member that deflects the air blown out from the discharge port by contacting the air; and a driving part which swings the turning member to change a turning angle of the air, the laundry treating apparatus further comprising: an outlet for discharging air in the accommodating chamber; an exhaust duct that guides air discharged from the discharge port to an outside of the case; and an opening/closing unit that opens and closes the exhaust duct.

According to the above configuration, the laundry is easily dried and wrinkles of the laundry are easily smoothed, as in the first aspect. Moreover, dust adhering to the clothes becomes easy to fall off.

Further, the exhaust duct can be closed or opened by the opening/closing portion as necessary. In particular, when supplying steam into the accommodating chamber to smooth wrinkles of the clothes, the exhaust duct can be closed, and leakage of the steam to the outside of the clothes treatment device can be suppressed. Therefore, the accommodating chamber is easy to fill with steam, the wrinkle smoothing effect of the clothes is improved, and the humidity rise around the clothes processing device can be inhibited.

In the present invention, the term "parallel" includes not only a parallel state but also a substantially parallel state.

A suction port 715 that opens forward is provided in the casing 712 on the front side of the fan 711, i.e., on the front surface of the cover 712b, and a discharge port 716 that opens upward is provided on the rear side of the fan 711. The suction port 715 is open in a direction along the bottom surface of the housing chamber 200, and has a lower end slightly higher than the bottom surface of the housing chamber 200. The suction port 715 is provided with a plurality of lattices 715a extending in a lattice shape. 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 axially long shapes.

A filter 717 is disposed between the suction port 715 and the fan 711 in the casing 712. The filter 717 traps dust sucked from the suction port 715 together with air.

The right end of the fan shaft 714 passes through the right side surface of the housing 712, and further passes through the right side surface of the storage chamber 200. A portion of the right side surface of the housing chamber 200 corresponding to the air circulation unit 700 is recessed inward, and a fan motor 713 is mounted on the outside of the portion. The fan shaft 714 penetrating the right side surface of the housing chamber 200 is coupled to a rotor (not shown) of the fan motor 713.

The fan motor 713 drives the fan 711 to rotate 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 vent plate mechanism 720 includes a vent plate 721 and a vent plate motor 722. The ventilation board 721 corresponds to the steering member of the present invention, and the ventilation board motor 722 corresponds to the driving portion of the present invention.

The ventilation plate 721 has a square shape elongated in the axial direction of the circulation fan 710, and has a size slightly larger than the discharge port 716 of the circulation fan 710. Eaves 723 are provided at both left and right ends of the ventilation plate 721, and a ventilation plate shaft 724 is provided at a lower end of the eaves 723. The circulation fan 710 is provided with a support portion 718 at the rear upper end portion of both side surfaces of the casing 712. The ventilation board shafts 724 on both sides of the ventilation board 721 are rotatably supported by the support portions 718 on both sides of the housing 712. Thereby, the ventilation plate 721 is positioned above the discharge port 716 and can swing in the vertical direction.

The right end of the vent plate shaft 724 penetrates the right support portion 718, and further penetrates the right side surface of the housing chamber 200. A ventilation board motor 722 is mounted above the fan motor 713 outside the right side surface of the housing chamber 200. The ventilation board shaft 724 penetrating the right side surface of the housing chamber 200 is coupled to a rotor (not shown) of the ventilation board motor 722.

The ventilation board motor 722 swings the ventilation board 721 via the ventilation board shaft 724 by rotating forward and backward by a predetermined rotation angle. The air blown upward from the discharge port 716 of the circulation fan 710 is turned by contacting the ventilation plate 721. The turning angle of the air changes with the angle of the swinging ventilation board 721, and the direction in which the air, i.e., wind, goes changes.

The fan shaft 714 of the circulation fan 710 is a rotation shaft when the fan 711 rotates, and the ventilation plate shaft 724 of the ventilation plate mechanism 720 is a swing shaft when the ventilation plate 721 swings. As shown in fig. 8, the circulation fan 710, i.e., the air circulation unit 700, is disposed at the bottom of the housing chamber 200 in the following state: the axial directions of the rotation shaft of the fan 711 and the swing shaft of the ventilation plate 721 are parallel or substantially parallel to the left-right direction, i.e., the front-rear direction of the laundry hung by the rod 261 of the hanger table 260. In other words, the rod 261 of the hanger table 260 holds the laundry in the upper portion of the receiving chamber 200 in a state that: the front-rear direction of the laundry hung on the rod 261 is parallel or substantially parallel to the axial direction of the rotation shaft of the fan 711 of the air circulation unit 700 and the oscillation shaft of the ventilation plate 721. At this time, in the circulation fan 710, the center in the axial direction of the rotation shaft of the fan 711 substantially coincides with the center of the rod 261.

A ventilation plate cover 280 covering the ventilation plate 721 is disposed in the housing chamber 200. The ventilation board cover 280 is mounted to an upper surface of the case 712 of the circulation fan 710 and a rear surface of the receiving chamber 200. The vent plate cover 280 corresponds to the cover portion of the present invention.

The ventilation board cover 280 is composed of a cover main body 281 which is curved in an arc shape and is long in the left-right direction, and side surface portions 282 which are provided on the left and right of the cover main body 281. When the ventilation board motor 722 rotates forward and backward, the ventilation board 721 swings about the swing shaft so that the tip end thereof draws an arc. The cover main body portion 281 covers the ventilation plate 721 in the radial direction of the arc drawn from the tip of the ventilation plate 721, and the left and right side surface portions 282 cover the ventilation plate 721 in the axial direction of the swing shaft. A plurality of opening portions 283 having a laterally elongated shape through which air, which is wind deflected by the ventilation board 721, passes are formed in the hood main body portion 281 so as to be aligned in the vertical and lateral directions. It is desirable that the arc of the cover main body portion 281 is formed to be approximately concentric with the arc drawn by the tip of the ventilation board 721.

An air mixing unit 800 is provided between the top surface of the housing chamber 200 and the top surface of the case 100 so as to be adjacent to the exhaust duct 610. The air mixing unit 800 sucks air outside the cabinet 100, i.e., outside the machine, and mixes it with air flowing in the exhaust duct 610.

Referring to fig. 6 (a), the air mixing unit 800 includes a mixing fan 810 and an introduction duct 820. The mixing fan 810 is a centrifugal fan, and includes a fan 812 and a motor 813 for rotating the fan 812 in a housing 811. The housing 811 has a suction port 814 on a side surface thereof and a discharge port 815 on a peripheral surface thereof. The mixing fan 810 may be a fan other than a centrifugal fan, such as an axial fan.

An inlet 612 is formed in the exhaust duct 610 downstream of the ozone removing filter 630 in the air flow. The introduction duct 820 has one end connected to the introduction port 612 and the other end connected to the discharge port 815 of the mixing fan 810.

An intake port 105 having a plurality of holes is provided in the rear surface of the casing 100. Suction port 814 of mixing fan 810 is connected to suction port 105. The suction port 105 may be spaced apart from the exhaust port 104 by a distance that air discharged from the exhaust port 104 is sucked in upon being discharged.

Fig. 9 is a side cross-sectional view showing a main part of the laundry treating apparatus 1 in a state where the rack 290 is used. In fig. 9, for convenience of explanation, the carriage 290 is not shown in cross section, and the right fixing portion 203 is shown.

The housing 200 is provided with a rack 290 for placing small articles so that small articles such as shoes, gloves, and dolls, which are difficult to hang on the hanger table 260, can be housed. The carriage 290 is disposed above the ventilation board cover 280.

Fig. 10 (a) to (d) are views showing the structure of the carriage 290. Fig. 10 (a) is a plan view of the carriage 290, and fig. 10 (b) is a cross-sectional view of the carriage 290 taken along the line a-a' in fig. 10 (a). Fig. 10 (c) and (d) are side views of the carriage 290 in the unfolded state and the folded state, respectively.

The carriage 290 includes a first frame 291 and a second frame 292 arranged in front and rear, and a hinge portion 293 connecting the first frame 291 and the second frame 292. The first frame 291 and the second frame 292 are lattice-shaped frames in which a plurality of lattices 291b, 292b are provided inside substantially square frames 291a, 292 a. Two support shafts 294 protruding to the left and right are formed at the rear end of the second frame 292. The hinge portion 293 includes a round bar-shaped shaft 295 provided at a rear end portion of the first frame 291, and a cylindrical boss 296 provided at a front end portion of the second frame 292 and through which the shaft 295 passes. As shown in fig. 10 (d), the carriage 290 can be folded in two by rotating the first holder 291 with respect to the second holder 292.

As shown in fig. 8 and 9, two right and left fixing portions 203 having shaft holes 203a are provided on the rear surface of the housing chamber 200. The carriage 290 is rotatably fixed to the fixing portion 203 by inserting the support shaft 294 of the second frame 292 through the shaft hole 203a of the fixing portion 203. Further, a plurality of rack support portions 204 are provided on the left and right side surfaces of the housing chamber 200 so as to be aligned in the front-rear direction.

When the rack 290 is not used, the rack 290 is set in a non-set state in which it is folded and stands along the rear surface of the storage chamber 200, as shown in fig. 8. Thus, the carrier 290 does not easily interfere with the clothes hung from the hanger table 260. On the other hand, when the rack 290 is used, as shown in fig. 9, the rack 290 is set in a state of being unfolded to be horizontally laid down forward of the rear surface of the storage compartment 200. At this time, the left and right sides of the carriage 290 are supported by the plurality of carriage supports 204 and held in the set state.

Fig. 11 is a block diagram showing the configuration of the laundry treatment apparatus 1.

In addition to the above configuration, the laundry processing apparatus 1 further 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 mode 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 controller 902 includes a microcomputer, various driving circuits, and the like, and controls the ozone generator 320, the heater 330, and the blower fan 340 of the first supply unit 300, the pump 461 and the heater 472 of the second supply unit 400, the exhaust shutter 620 of the exhaust unit 600, the fan motor 713 and the louver motor 722 of the air circulation unit 700, the mixing fan 810 of the air mixing unit 800, and the like.

The laundry processing apparatus 1 of the present embodiment can execute a deodorization/sterilization operation for performing deodorization/sterilization on laundry, a drying operation for drying laundry, and a wrinkle smoothing operation for smoothing wrinkles of laundry.

Fig. 12 is a flowchart showing operation control of the laundry treatment apparatus 1.

When the operation for starting the operation is performed, the control section 902 determines that any one of the deodorization/sterilization operation, the drying operation, and the wrinkle smoothing operation has been selected (S1).

When the deodorization/sterilization operation is selected (S1: deodorization/sterilization), the deodorization/sterilization operation is started and the controller 902 executes the deodorization/sterilization process (S2). In the deodorization and sterilization process, the controller 902 operates the blower fan 340 and the ozone generator 320 in the first supply unit 300. Before the operation is started, that is, when the laundry treating apparatus 1 is in the stopped state, the opening/closing plate 621 of the air shutter plate 620 is located at the open position. The control unit 902 does not operate the exhaust shutter plate 620 and maintains the opening/closing plate 621 at the open position.

As shown by the solid arrows in fig. 5, the air outside the machine is sucked into the intake duct 350 through the intake port 101 by the operation of the blower fan 340, and is 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 in the ozone generator 320 is mixed into the air. Thus, the air containing ozone passes through the first supply line 310, reaches the first supply port 210, and is discharged from the first supply port 210 into the housing chamber 200. The discharged air containing ozone collides with 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. Thus, the air containing ozone is diffused by the cover 240 and then travels to the clothes above, and comes into contact with the clothes over a large area. The clothes are deodorized and sterilized by the deodorizing and sterilizing action of ozone.

As shown by the one-dot chain line arrow in fig. 6 (a), the air whose ozone concentration has been reduced by performing deodorization and sterilization of the laundry is discharged from the discharge port 202 provided on the top surface of the storage compartment 200 into the exhaust duct 610, flows through the exhaust duct 610, and is discharged from the exhaust port 104 to the outside of the machine. The air flowing in the exhaust duct 610 passes through the ozone removing filter 630. Thereby, ozone in the air is removed, and the air reduced to an appropriate ozone concentration is discharged to the outside of the machine.

Further, in the deodorization and sterilization process, the controller 902 drives the fan motor 713 to operate the circulation fan 710 and drives the ventilation board motor 722 to swing the ventilation board 721 in the vertical direction in the air circulation unit 700. In this case, the ventilation board 721 may continuously swing or may stop for a predetermined time every time it swings back and forth or a plurality of times it swings back and forth.

As shown in fig. 7 (a), the air containing ozone in the storage chamber 200 is taken into the housing 712 through the suction port 715 and blown out through the discharge port 716 as an ozone wind. The blown ozone wind is deflected by the ventilation board 721, and then travels toward the clothes through the plurality of openings 283 of the ventilation board cover 280. At this time, the ventilation board 721 swings and the turning angle of the ozone wind changes, so that the ozone wind comes into contact with the laundry from all directions. This improves the efficiency of contact between the ozone wind and the clothes, and makes it easier to deodorize and sterilize the clothes. In addition, the laundry is blown by ozone wind from various directions, so that the hung laundry is shaken. This makes it possible to cause ozone to reach portions of the clothing, such as underarm portions, which are difficult to reach when the clothing is at rest. In addition, dust attached to the laundry easily falls.

Further, the laundry is hung on the rod 261 of the laundry stand 260 such that the front-rear direction thereof is parallel to the axial direction of the swing shaft of the ventilation plate 721 of the air circulation unit 700. Therefore, even when a plurality of clothes are stored in the storage chamber 200 as shown in fig. 7 (a), the ozone wind discharged from the circulation fan 710 and deflected by the ventilation plate 721 easily passes through the space between the clothes and touches the upper portion of the storage chamber 200. Therefore, the ozone wind can easily contact with a plurality of clothes in all directions, and can well deodorize and sterilize the plurality of clothes.

When a predetermined deodorization/sterilization time has elapsed, the controller 902 stops the operation of the ozone generator 320, the blower fan 340, the circulation fan 710, and the ventilation plate 721, and terminates the deodorization/sterilization process. Thus, the deodorization/sterilization operation is ended.

Next, when controller 902 determines that the drying operation is selected in step S1 (S1: drying), the drying operation is started and the drying process is executed (S3). In the drying process, the control part 902 operates the blower fan 340 and the heater 330 in the first supply unit 300.

As shown by the solid arrows in fig. 5, the air outside the machine is sucked into the suction duct 350 through the suction port 101 and is sent into the first supply duct 310 by the operation of the blower fan 340.

As shown in fig. 2, the air flowing through first supply duct 310 is heated by heater 330 to become warm air at a temperature suitable for drying (e.g., about 60 ℃). Then, 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 as well as the air containing ozone, and then, the air goes to the clothes above, and comes into contact with the clothes over a large area. Thereby, the laundry is dried.

In the circulation drying process, the control section 902 operates the circulation fan 710 in the air circulation unit 700 and swings the ventilation board 721 in the up-down direction.

As shown in fig. 7 (a), the air in the storage chamber 200 heated by the supply of the warm air is taken into the housing 712 through the intake port 715 and blown out through the discharge port 716 as the warm air. The blown warm air is turned by the oscillating ventilation board 721, thereby coming into contact with the laundry from various directions. This improves the efficiency of contact between the warm air and the clothes, and the clothes are easily dried. Further, by shaking the clothes, warm air can be made to touch a portion of the clothes that is difficult to touch in a state where the clothes are stationary, and dust attached to the clothes becomes easy to drop.

Further, as in the case of the deodorization and sterilization operation, even when a plurality of clothes are stored in the storage chamber 200 as shown in fig. 7 (a), the warm air discharged from the circulation fan 710 and turned around by the ventilation plate 721 easily passes through between the clothes and touches the upper portion of the storage chamber 200. Therefore, the warm air is easy to contact with a plurality of clothes in all directions, and the plurality of clothes are easy to dry.

As shown by the solid arrows in fig. 6 (a), the air from which moisture has been removed from the clothes in the storage chamber 200 is discharged from the outlet 202. The outlet 202 is provided on the top surface of the housing chamber 200, and heated air is easily discharged. The discharged air flows through the exhaust duct 610 and passes through the ozone removing filter 630. At this time, ozone removing filter 630 becomes resistance, and the flow rate of air decreases.

During the drying process, controller 902 operates air mixing unit 800, i.e., mixing fan 810. As shown by the broken-line arrows in fig. 6 (a), the air outside the machine is taken in from the air inlet 105 and is supplied to the exhaust duct 610 through the introduction duct 820 to a position downstream of the ozone removing filter 630. The air from the outside supplied into the exhaust duct 610 is mixed with the air from the storage chamber 200 passing through the ozone removing filter 630. In this case, since the flow rate of the air from the storage chamber 200 is reduced, the air from the outside of the machine is easily mixed. By mixing the air from the outside, the relative humidity of the air from the storage chamber 200 is reduced. As shown by the hollow arrows in fig. 6 (a), the air with reduced relative humidity is discharged from the exhaust port 104 to the outside of the machine. Accordingly, the periphery of the laundry treatment apparatus 1 is less likely to be affected by high-humidity air, such as condensation on the wall surface of a room located around the laundry treatment apparatus 1 due to the discharged air.

When a predetermined drying time has elapsed, controller 902 stops heater 330, blower fan 340, circulation fan 710, ventilation board 721, and mixing fan 810 to complete the drying process. Thus, the drying operation is ended.

Next, when the control unit 902 determines that the wrinkle smoothing operation is selected in step S1 (S1: wrinkle smoothing), the wrinkle smoothing operation is started, and a preparation process is executed (S4). In the preparation process, the controller 902 operates the heater 472 of the steam generator 470 in the second supply unit 400 with the pump 461 stopped. Thereby, the temperature of the body part 471 of the steam generator 470 gradually rises.

Further, in the preparation process, the control unit 902 operates the circulation fan 710 in the air circulation unit 700 and swings the ventilation board 721 in the up-down direction. As shown in fig. 7 (a), the air in the storage chamber 200 is taken into the housing 712 through the intake port 715 and blown out as wind through the discharge port 716. The blown wind is turned by the swinging ventilation board 721, thereby coming into contact with the laundry from various directions, shaking the laundry. Thereby, the dust becomes easy to fall from the laundry.

When the temperature of the body part 471 of the steam generator 470 is sufficiently high, the control part 902 ends the preparation process and performs the steam process (S5). During the steam operation, the control unit 902 operates the exhaust shutter plate 620 to switch the opening/closing plate 621 from the open position to the closed position. Thereby, the exhaust duct 610 is closed. Next, the control unit 902 operates the pump 461 with the heater 472 continuously 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, reaches the second supply port 220, and is discharged from the second supply port 220 into the housing chamber 200. The discharged steam hits the cover 240 and spreads around, some of which are discharged through the plurality of discharge holes 244, and the rest of which are discharged between the cover 240 and the bottom surface of the storage chamber 200. Thus, the steam is diffused through the cover 240 and goes to the upper laundry, contacting the laundry over a large area. The wrinkles of the laundry are smoothed by the moisture and heat of the steam.

When steam flows through second supply pipe 410, a part of the steam may condense to generate condensed water. The dew condensation water flows downward and is accumulated in the water reservoir 413, and is discharged from the discharge port 414. The drained dew condensation water is recovered to the drain tank 480 through the drain hose 490. In this way, in the present embodiment, since the water reservoir 413 for storing the dew condensation water is provided below the introduction port 412 of the second supply duct 410, the dew condensation water can be prevented from flowing from the introduction port 412 to the inside of the steam generator 470.

Further, the circulation fan 710 and the ventilation board 721 continue to operate during the steam process. The clothes are shaken by the wind blown out from the discharge port 716 and diverted by the ventilation plate 721. When the laundry is shaken in a suspended state, a force such as a centrifugal force is easily applied to the laundry. Thereby, the surface of the laundry hit by the steam is easily smoothed, and thus, wrinkles of the laundry become easily flattened. Further, although the laundry is not in a dry state during preparation since it is wetted with the steam, dust attached to the laundry can be dropped by shaking the laundry.

Further, as in the case of the deodorization and sterilization operation, even when a plurality of clothes are stored in the storage chamber 200 as shown in fig. 7 (a), the wind discharged from the circulation fan 710 and deflected by the ventilation plate 721 easily passes through between the clothes and touches the upper portion of the storage chamber 200. Therefore, wind easily contacts with a plurality of clothes in all directions, the plurality of clothes are well shaken, and wrinkles of the clothes are easily flattened.

During the steam process, the exhaust duct 610 is in a closed state. Therefore, the steam in the storage compartment 200 can be prevented from being discharged to the outside of the machine through the exhaust duct 610. Further, in the exhaust duct 610, the ozone removing filter 630 is provided downstream of the exhaust shutter plate 620, and therefore, it is possible to prevent the ozone removing filter 630 from being seriously wetted by the contact of the steam with the ozone removing filter 630.

When a predetermined steam supply time has elapsed, the controller 902 stops the heater 472 and the pump 461, and the steam process is terminated.

Next, the control section 902 performs a drying process (S6). The drying course is the same as the drying course in the drying operation, the blowing fan 340 and the heater 330 are operated, and the circulation fan 710 and the ventilation board 721 are also continuously operated. Thereby, the laundry wetted with the steam is dried. The drying time in the wrinkle smoothing operation may be set to be suitable for the wrinkle smoothing operation, and may be set to be different from the drying time in the drying operation.

In the drying process, the control unit 902 operates the exhaust shutter 620 to switch the opening/closing plate 621 to the open position. At this time, the control portion 902 controls the exhaust shutter 620 as follows: the opening/closing plate 621 does not move to the open position at a time, but opens in stages at a predetermined angle, for example, 30 degrees each time, as time passes. Since the opening amount of the communication port 611 of the exhaust duct 610 gradually increases, the air with high humidity is discharged little by little without being discharged from the storage chamber 200.

Accordingly, since the humidity in the storage chamber 200 is not rapidly decreased, the wrinkle smoothing effect of the laundry is maintained for a certain period of time even during the drying process. Further, if air containing a large amount of moisture is discharged from the housing chamber 200 at a time, when the air passes through the ozone removing filter 630, the moisture becomes easy to adhere to the ozone removing filter 630. Therefore, the air containing a large amount of moisture is slowly discharged from the housing chamber 200, thereby suppressing the adhesion of moisture to the ozone removing filter 630.

Further, similar to the drying operation, controller 902 operates mixing fan 810. Thereby, the air from the outside of the machine is mixed with the air from the storage chamber 200, and the air having the lowered relative humidity is discharged from the exhaust port 104 to the outside of the machine.

When the predetermined drying time elapses and the drying process is ended, the controller 902 performs the ventilation process (S7). That is, the control part 902 keeps the circulation fan 710 and the ventilation board 721 operated next to the drying process. The air inside the housing chamber 200 is sucked from the suction port 715 and blown out into the housing chamber 200 from the discharge port 716, so that the air outside the machine is sucked into the housing chamber 200 from the first supply port 210 through the suction duct 350 and the first supply duct 310 of the first supply unit 300, and the air inside the housing chamber 200 is discharged outside the machine through the discharge port 202 and the exhaust duct 610. This allows the inside of the housing chamber 200 to be ventilated, and the inner wall and the like in the housing chamber 200 are dried even if they are wetted with steam.

The mixing fan 810 may be kept in operation during ventilation. In this case, the air from the storage chamber 200 can be discharged to the outside of the machine after the relative humidity is reduced, as in the drying process.

When a predetermined ventilation time has elapsed, the controller 902 stops the operation of the circulation fan 710 and the ventilation board 721, and ends the ventilation process. Thus, the wrinkle smoothing operation is ended.

In this way, during the wrinkle smoothing operation, the exhaust duct 610 is closed by the exhaust shutter 620 during the steam flow, and the steam cannot be discharged from the storage chamber 200 to the outside of the machine. Accordingly, during the wrinkle smoothing operation, the amount of moisture discharged from the laundry treatment apparatus 1 to the outside is reduced, and therefore, the humidity around the laundry treatment apparatus 1 is not likely to be increased.

In addition, in a case where the hanger is not firmly hung on the hanger stand 260, the laundry may fall down when the laundry is shaken by hitting the wind from the air circulation unit 700. In the present embodiment, since the ventilation board 721 is covered with the ventilation board cover 280, it is possible to prevent the dropped clothes from pressing on the ventilation board 721 to stop the ventilation board 721.

In the laundry treatment apparatus 1 of the present embodiment, small articles such as shoes can be dried, deodorized and sterilized by the drying operation and the deodorizing and sterilizing operation. In this case, as shown in fig. 9, a rack 290 is provided in the storage chamber 200, and small articles are placed on the rack 290. At this time, since the carriage 290 is fixed to the rear surface of the storage compartment 200, the user can easily deform the carriage 290 into the set state by simply grasping the tip end side of the folded carriage 290 and unfolding the carriage 290 while laying it upside down. In operation, the warm air and the ozone air blown out from the circulation fan 710 and deflected by the ventilation board 721 pass through between the lattices 291b, 292b of the carriage 290 to come into contact with the small objects.

In addition to the deodorizing and sterilizing operation, the drying operation, and the wrinkle smoothing operation, the laundry processing apparatus 1 may perform a drying deodorizing and sterilizing operation in which, for example, deodorizing and sterilizing are performed after drying.

In addition, a temperature sensor and a humidity sensor may be disposed in the housing chamber 200. In this case, the drying process may be terminated according to the temperature and humidity in the storage chamber 200 during the drying operation and the wrinkle smoothing operation. Further, the opening angle of the opening/closing plate 621 may be gradually increased according to the change of the temperature and humidity in the housing chamber 200 during the drying process in the wrinkle smoothing operation.

< effects of the embodiment >

As described above, according to the present embodiment, when the laundry is dried by supplying the warm air from the first supply unit 300, the air circulation unit 700 is operated, so that the warm air can be brought into contact with the laundry in the storage compartment 200 from various directions. This improves the efficiency of contact between the warm air and the clothes, and the clothes are easily dried. Further, since the clothes are shaken by warm air from various directions, the warm air can be made to contact a portion of the clothes that is difficult to contact in a stationary state of the clothes, and dust attached to the clothes is likely to fall off.

Further, according to the present embodiment, the laundry in the storage compartment 200 can be shaken by operating the air circulation unit 700 when steam is supplied from the second supply unit 400 to apply steam to the laundry to smooth wrinkles of the laundry. This makes it easy for the wrinkles of the laundry to be flattened out, and also makes it possible to drop off dust adhering to the laundry.

Further, according to the present embodiment, the rod 261 of the hanger table 260 holds a plurality of clothes side by side in such a manner that the front-rear direction of the clothes is parallel to the axial direction of the swing shaft of the ventilation plate 721 of the air circulation unit 700. Therefore, even when a plurality of clothes are stored in the storage chamber 200, the wind discharged from the circulation fan 710 and deflected by the ventilation plate 721 easily passes through between the clothes and touches the upper portion of the storage chamber 200. Accordingly, the wind easily comes into contact with the plurality of clothes in all directions, so that the plurality of clothes are easily dried, and wrinkles of the plurality of clothes are easily smoothed.

Further, according to the present embodiment, since the ventilation board 721 is covered with the ventilation board cover 280, even if the hung laundry falls, the laundry is prevented from pressing on the ventilation board 721 to stop the ventilation board 721.

Further, according to the present embodiment, in the ventilation board cover 280, the cover main body portion 281 covering the ventilation board 721 in the radial direction of the arc drawn from the tip end of the ventilation board 721 has a plurality of opening portions 283 and is formed in an arc shape. Accordingly, when the ventilation board 721 swings, the distances between the tip end of the ventilation board 721 and the openings 283 are almost equal, and thus air can be blown out from the openings 283 with almost equal force. When the clothes fall on the cover main body portion 281 which is the ventilation board cover 280, the clothes easily slip off the cover main body portion 281, and the opening portions 283 are not easily clogged with the clothes. Further, since a useless space is not easily generated between the cover main body portion 281 and the ventilation plate 721, the storage space for the clothes in the storage chamber 200 is not easily reduced accordingly.

Further, according to the present embodiment, since small articles such as shoes which are difficult to hang on the hanger table 260 can be placed on the placement rack 290 provided in the housing chamber 200, the small articles can be dried, deodorized, and sterilized.

Further, according to the present embodiment, the carriage 290 is fixed to the rear surface of the storage compartment 200 by the fixing portion 203 and is deformable to a non-set state in which it is folded and raised along the rear surface and a set state in which it is unfolded and laid down to the front of the rear surface. Thus, when the rack 290 is not used, the hung laundry is not easily obstructed by the rack 290 being in the non-installed state. In addition, when the carriage 290 is used, the carriage 290 can be easily deformed into the set state by grasping the tip end side of the folded carriage 290 and unfolding the carriage 290 while laying it upside down.

Further, according to the present embodiment, since the exhaust damper 620 is provided in the exhaust duct 610, the exhaust duct 610 can be closed or opened as needed. In particular, when the steam is supplied into the housing chamber 200 to smooth wrinkles of the laundry, the exhaust duct 610 can be closed by the exhaust shutter 620, and leakage of the steam to the outside of the machine can be suppressed. This facilitates filling of the inside of the storage chamber 200 with steam, improves the wrinkle smoothing effect of the laundry, and suppresses an increase in humidity around the laundry treatment apparatus 1.

While the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications other than those described above may be made to the embodiments of the present invention.

For example, in the above embodiment, both ozone and warm air are supplied from the first supply unit 300 into the housing chamber 200. However, the laundry treatment apparatus 1 may be provided with an ozone supply unit for supplying ozone and a warm air supply unit for supplying warm air.

In the above embodiment, the air circulation unit 700 is disposed on the bottom surface of the housing chamber 200 and in the vicinity of the rear surface so that the axial direction of the rotation shaft of the fan 711 and the swing shaft of the ventilation plate 721 is the left-right direction. However, the air circulation unit 700 may be disposed on the bottom surface of the housing chamber 200 in the vicinity of the right side surface or the left side surface so that the axial direction of the rotation shaft of the fan 711 and the swing shaft of the ventilation plate 721 is the front-rear direction. In this case, the hanger table 260 is disposed on the top surface of the accommodation chamber 200 such that the extending direction of the rod 261 is the front-rear direction.

Further, in the above embodiment, the air circulation unit 700 is disposed at the bottom of the housing chamber 200 and inside the housing chamber 200. However, the air circulation unit 700 may be disposed at the bottom of the housing chamber 200 and outside the housing chamber 200. In this case, an intake port for taking in air to the circulation fan 710 and an outlet port for blowing out air into the housing chamber 200 are provided in a wall surface of the housing chamber 200. The air circulation unit 700 may be disposed at a portion other than the bottom of the housing chamber 200 and may be disposed at any one of the inner and outer sides of the housing chamber 200.

Further, in the above embodiment, the cover main body portion 281 of the ventilation board cover 280 is formed with a plurality of opening portions 283 having a laterally elongated shape. However, the shape of the opening 283 is not limited to the above shape, and for example, a vertically elongated shape may be adopted.

Further, in the above embodiment, the ventilation board cover 280 is constituted by the cover main body portion 281 having an arc shape and the left and right side surface portions 282. However, as long as the ventilation board cover 280 has a plurality of openings 283 and covers the ventilation board 721, a structure other than the above-described structure may be employed.

Further, in the above embodiment, the carriage 290 is constituted by two first and second holders 291 and 292, and can be folded in two. However, the carriage 290 may be formed of one rack without being folded, or may be formed of three or more racks and be folded into three or more.

Further, in the above embodiment, the carriage 290 is fixed to the fixing portion 203 provided on the rear surface of the storage chamber 200. However, the carriage 290 may be fixed to the fixing portion 203 provided on the right side surface or the left side surface of the storage chamber 200.

Further, in the above embodiment, the exhaust duct 610 is opened little by the exhaust damper 620 as time passes during the drying process in the wrinkle smoothing operation, but may be opened at once.

Further, in the above embodiment, the discharge port 202 is provided on the top surface of the housing chamber 200. However, the discharge port 202 may be provided at another position, for example, at an upper portion of the rear surface of the housing chamber 200.

Further, in the above embodiment, the ozone removing filter 630 is an activated carbon/catalyst filter, but other filters having ozone removing performance such as an activated carbon filter may be used.

Further, in the above embodiment, the clothes treating apparatus 1 performs the deodorization and sterilization operation. However, the laundry treatment apparatus 1 may not perform the deodorization and sterilization operation, and the ozone generator 320 may not be disposed in the first supply unit 300. In this case, the ozone removing filter 630 is removed from the exhaust unit 600.

Further, in the above embodiment, the steam generator 470 of the second supply unit 400 has the following structure: the water sent from the pump 461 falls to the bottom surface of the high-temperature steam generation chamber 473 and evaporates, thereby generating steam. However, the steam generator 470 is not limited to the above configuration, and may be configured to generate steam by heating a water tank storing water to boil the water, for example.

Further, although the cross-flow fan is used as the circulation fan 710 in the above embodiment, a fan other than the cross-flow fan such as a sirocco fan (sirocco fan) may be used.

Further, in the above embodiment, the exhaust shutter 620 is used as an opening/closing portion for opening/closing the exhaust duct 610. However, other opening/closing units may be used, such as a flap mechanism including a flap (shutter) that moves up and down in the exhaust duct 610 and a driving unit that drives the flap.

In addition, the embodiment of the present invention can be modified in various ways as appropriate within the scope of the technical idea shown in the claims.
