Description

Clothes treating apparatus

Technical Field

The present invention relates to a laundry treatment apparatus that performs a process such as drying and wrinkle smoothing on laundry.

Background

Conventionally, there is known a clothes treating apparatus in which clothes are hung in a storage portion, and wrinkles of the clothes can be smoothed out by drying the clothes by warm air or by steam. For example, patent document 1 describes an example of such a laundry treatment apparatus.

In the above-described laundry treatment apparatus, if the contact efficiency of warm air with laundry is poor, the drying efficiency may be deteriorated, and thus it is difficult to improve the drying performance. Therefore, in order to improve drying performance, it is sought to improve the contact efficiency of warm air with laundry.

In the above-described laundry treatment apparatus, the surface of the laundry contacted by the steam is smoothed by the self weight of the laundry, and wrinkles of the laundry are removed, but if a larger force that smoothes the surface of the laundry can be applied to the laundry, the performance of smoothing wrinkles can be improved.

Disclosure of Invention

Problems to be solved by the invention

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

Solution for solving the problem

The laundry treatment apparatus according to the main aspect of the present invention comprises: a housing chamber disposed in the case for housing the laundry in a suspended state; a warm air supply unit for supplying warm air into the storage room; a steam supply unit configured to supply steam into the storage chamber; and an air circulation unit that sucks in air in the housing chamber and blows the air into the housing chamber. Wherein the air circulation part includes: a circulation fan for blowing out air sucked from the air inlet through the air outlet; a turning member which is in contact with the air blown out from the outlet and turns the air; and a driving part swinging the steering member to change the steering angle of the air. Further, the laundry treatment apparatus includes: a discharge port for discharging air in the housing chamber; an exhaust duct guiding air discharged from the discharge port to an outside of the case; and an air mixing part sucking air outside the case and mixing it with air flowing in the exhaust duct.

The circulating fan may be, for example, a cross flow fan including a fan having an impeller arranged in a cylindrical shape and having an axial dimension larger than a radial dimension.

According to the above configuration, when drying clothes, warm air is supplied into the housing chamber by the warm air supply unit, and the air circulation unit can be operated at this time. In this case, the air in the housing 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 directed to the clothes. At this time, the steering angle of the warm air is changed by the swing of the steering member, and thus the warm air comes into contact with the laundry from various directions. Thus, the contact efficiency between the warm air and the laundry becomes high, and the laundry is easily dried.

Further, the warm air contacts the laundry from various directions, that is, the direction in which the warm air blows the laundry changes, and thus the hung laundry may shake. Thus, warm air can be made to reach portions of the clothing, such as the armpit portion, which are difficult to reach in the resting state of the clothing. In addition, dust attached to the laundry becomes easy to fall.

In addition, when the wrinkles of the clothes are smoothed, the steam is supplied into the accommodating chamber by the steam supply part, and at this time, the air circulation part can be operated. In this case, the air in the housing chamber is taken in from the intake port and blown out from the discharge port as wind. The blown wind is deflected by the swinging deflector 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. This makes it easy to flatten the surface of the clothing against which the steam hits, and thus the wrinkles of the clothing are easily flattened. In addition, by shaking the laundry, dust attached to the laundry can be dropped.

Further, when the laundry is dried, by operating the air mixing portion, the air from the outside of the casing can be mixed with the air from the housing chamber in the exhaust duct so that the relative humidity is reduced, and then the air can be discharged to the outside of the casing. This makes it difficult for the discharged air to cause the influence of highly humid air such as dew condensation on the wall surface of the room around the laundry treatment apparatus on the periphery of the laundry treatment apparatus.

In the laundry treatment apparatus according to the present aspect, the laundry treatment apparatus may further include an opening/closing portion for opening/closing the exhaust duct.

According to the above structure, the exhaust duct can be closed or opened as needed.

In the case of adopting the above configuration, the steam generator may further include a control unit that performs a steam process of supplying steam into the storage chamber by the steam supply unit. In this case, the control portion controls the opening and closing portion to close the exhaust duct during the steam.

With such a configuration, the steam leakage to the outside of the cabinet during the steam process can be suppressed, and therefore, the storage chamber is easily filled with steam, the wrinkle smoothing effect of the laundry is improved, and the rise in humidity around the laundry treatment apparatus can be suppressed.

In the case of adopting the above-described structure, further, the following structure may be adopted: after the steam course, the control part then performs a drying course of supplying warm air into the accommodating chamber through the warm air supply part, and during the drying course, the control part controls the opening and closing part to open the exhaust duct.

With such a structure, warm air, i.e., air from which moisture is peeled off from laundry during drying can be discharged to the outside of the cabinet, and laundry becomes easy to dry.

In the case of adopting a structure in which the opening/closing portion is provided in the exhaust duct, the structure may be further provided with: an ozone supply unit configured to supply air containing ozone into the housing chamber; and an ozone removing unit that is disposed downstream of the opening/closing unit in the exhaust duct and removes ozone contained in air flowing through the exhaust duct.

In the case of such a configuration, when deodorizing clothes, the air circulation unit can be operated at this time by supplying air containing ozone into the housing chamber through the ozone supply unit. In this case, the ozone-containing air in the housing chamber is taken in from the intake port and blown out from the discharge port as an ozone wind. The blown ozone wind is turned by the turning member that swings, thereby coming into contact with the laundry from various directions. Thus, the contact efficiency between the ozone wind and the laundry becomes high, and the laundry becomes easy to be deodorized. Further, by shaking the laundry, ozone can be made to reach a portion of the laundry that is difficult to reach in a stationary state of the laundry, and dust attached to the laundry becomes easy to fall off.

Further, since the ozone removing portion is provided in the exhaust duct, air from which ozone is removed by the ozone removing portion can be discharged to the outside of the laundry treatment apparatus. Further, since the ozone removing section is disposed downstream of the opening/closing section, the opening/closing section is closed when the steam is supplied into the housing chamber, thereby preventing the ozone removing section from being wetted with the steam and preventing the ozone removing performance of the ozone removing section from being lowered.

In the case of adopting the above-described structure, further, the following structure may be adopted: the air mixing unit supplies air taken in from the outside of the case to the exhaust duct downstream of the ozone removing unit.

With such a configuration, the air outside the case can be mixed with the air from the housing chamber, which has a reduced flow rate due to passing through the ozone removal unit. As a result, the air from the outside is easily mixed with the air from the storage chamber, and therefore, the relative humidity of the air discharged to the outside is easily reduced.

According to the present invention, it is possible to provide a laundry treating apparatus capable of improving drying and wrinkle smoothing performance.

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 those of the fan 711. That is, the suction port 715 and the discharge port 716 have axially long shapes.

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

The right end of the fan shaft 714 penetrates the right side surface of the housing 712 and further penetrates the right side surface of the housing 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 outside 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 through the suction port 715, and the sucked air is sent by the fan 711 and blown out through the discharge port 716.

The ventilation board mechanism 720 includes a ventilation board 721 and a ventilation board motor 722. The ventilation plate 721 corresponds to the steering member of the present invention, and the ventilation plate motor 722 corresponds to the driving unit 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 slightly larger size than the discharge port 716 of the circulation fan 710. Eave portions 723 are provided at both left and right end portions of the ventilation plate 721, and a ventilation plate shaft 724 is provided at a lower end portion of the eave portions 723. The circulation fan 710 is provided with a support 718 at the rear upper end 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 supporting portions 718 on both sides of the housing 712. Thus, the ventilation plate 721 is located above the discharge port 716 and can swing in the up-down direction.

The right end of the ventilation board shaft 724 passes through the right support 718 and further passes through the right side surface of the housing chamber 200. A ventilation board motor 722 is mounted above the fan motor 713 on the outer side of 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 louver motor 722 swings the louver 721 via the louver shaft 724 by rotating forward and backward by a prescribed rotation angle. The air blown upward from the discharge port 716 of the circulation fan 710 is turned by contact with the ventilation plate 721. The steering angle of the air changes with the angle of the swing ventilation plate 721, and the direction in which the air, i.e., the wind, is directed changes.

The fan shaft 714 of the circulation fan 710 is a rotation shaft when the fan 711 rotates, and the louver shaft 724 of the louver mechanism 720 is a swing shaft when the louver 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 room 200 in the following state: the rotation axis of the fan 711 and the axial direction of the swing axis 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 lever 261 of the hanger 260. In other words, the lever 261 of the hanger stand 260 holds the laundry in the upper portion of the receiving chamber 200 in the following state: the front-rear direction of the laundry hanging on the lever 261 is parallel or substantially parallel to the rotation axis of the fan 711 of the air circulation unit 700 and the axial direction of the swing axis of the ventilation plate 721. At this time, in the circulation fan 710, the center of the rotation shaft of the fan 711 in the axial direction substantially coincides with the center of the lever 261.

An air mixing unit 800 is provided between the top surface of the housing room 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 in air outside the case 100, i.e., outside the machine, and mixes it with air flowing in the exhaust duct 610. The air mixing unit 800 corresponds to an air mixing section of the present invention.

Referring to fig. 6 (a), the air mixing unit 800 includes a mixing fan 810 and an introduction duct 820. The hybrid 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 formed in a side surface thereof and a discharge port 815 formed in a peripheral surface thereof. The mixing fan 810 may use a fan other than a centrifugal fan, such as an axial fan.

An inlet 612 is formed in the exhaust duct 610 at a position downstream of the ozone removal filter 630 with respect to the air flow. One end of the introduction duct 820 is connected to the inlet 612, and the other end is connected to the discharge port 815 of the mixing fan 810.

An air inlet 105 formed of a plurality of holes is provided on the rear surface of the casing 100. The suction port 814 of the mixing fan 810 is connected to the suction port 105. The suction port 105 may be spaced apart from the exhaust port 104 by a distance from which air discharged from the exhaust port 104 is sucked just after being discharged.

Fig. 9 is a block diagram showing the configuration of the laundry treating apparatus 1.

The laundry treatment apparatus 1 includes an operation unit 901 and a control unit 902 in addition to the above-described configuration.

The operation unit 901 includes operation buttons such as a selection button for selecting an operation mode and a start button for starting an 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 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 ventilation plate motor 722 of the air circulation unit 700, the mixing fan 810 of the air mixing unit 800, and the like.

The laundry treatment apparatus 1 according to the present embodiment can perform a deodorizing and sterilizing operation for deodorizing and sterilizing laundry, a drying operation for drying laundry, and a wrinkle smoothing operation for smoothing wrinkles of laundry.

Fig. 10 is a flowchart showing operation control of the laundry treatment apparatus 1.

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

When the deodorizing and degerming operation is selected (S1: deodorizing and degerming), the deodorizing and degerming operation is started, and the control unit 902 executes a deodorizing and degerming process (S2). During the deodorization and sterilization process, the control part 902 operates the blower fan 340 and the ozone generator 320 in the first supply unit 300. When the laundry treating apparatus 1 is in a stopped state before the start of operation, the opening/closing plate 621 of the air release shutter 620 is located at the open position. The control unit 902 does not operate the air release shutter 620, and maintains the open/close plate 621 in the open position.

As shown by solid arrows in fig. 5, by the operation of the blower fan 340, the air outside the machine is taken into the suction duct 350 from the suction 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, ozone generated in the ozone generator 320 is mixed into the air. In this way, the air containing ozone passes through the first supply duct 310, reaches the first supply port 210, and is discharged from the first supply port 210 into the housing chamber 200. The discharged air containing ozone collides with the cover 240 and spreads to the surrounding, 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 housing room 200. In this way, the ozone-containing air is diffused through the cover 240 and then goes upward to contact the laundry over a large area. The laundry is deodorized and sterilized by the deodorizing and sterilizing action of ozone.

As shown by the one-dot chain line arrows in fig. 6 (a), the air having the ozone concentration reduced by the deodorizing and sterilizing operation of the laundry is discharged from the discharge port 202 provided on the top surface of the housing room 200 into the exhaust duct 610, flows through the exhaust duct 610, and is discharged from the exhaust port 104 to the outside. Air flowing in the exhaust duct 610 passes through the ozone removal filter 630. Thereby, ozone in the air is removed, and the air reduced to an appropriate ozone concentration is discharged outside the machine.

Further, during deodorization and sterilization, the control unit 902 drives the fan motor 713 in the air circulation unit 700 to operate the circulation fan 710, and drives the ventilation board motor 722 to swing the ventilation board 721 in the up-down direction. In this case, the ventilation plate 721 may be continuously swung, or may be stopped for a predetermined time every one or more times of the reciprocating swing.

As shown in fig. 7 (a), ozone-containing air in the housing chamber 200 is taken into the casing 712 through the inlet 715, and is blown out from the outlet 716 as an ozone wind. The blown ozone air is turned by the ventilation plate 721 and then directed to the laundry through the plurality of openings 283 of the ventilation plate cover 280. At this time, the ventilation board 721 swings so that the turning angle of the ozone wind is changed, and thus the ozone wind is brought into contact with the laundry from various directions. Thus, the contact efficiency between the ozone wind and the clothes becomes good, and the clothes become easy to deodorize and sterilize. In addition, the laundry is blown by the ozone wind from various directions, so that the hung laundry may shake. Thus, ozone can be made to reach portions of the clothing, such as the armpit portion, which are difficult to reach in the resting state of the clothing. In addition, dust attached to the laundry is easily dropped.

Further, the laundry is hung on the lever 261 of the hanger 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 laundry items 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 between the laundry items and reaches the upper portion of the storage chamber 200. Thus, the ozone wind is easy to contact with a plurality of clothes in all directions, and the plurality of clothes can be well deodorized and sterilized.

When a predetermined deodorizing and sterilizing time elapses, the control unit 902 stops the operation of the ozone generator 320, the blower fan 340, the circulation fan 710, and the ventilation plate 721, and ends the deodorizing and sterilizing process. Thus, the deodorizing and degerming operation is ended.

Next, when the control unit 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). During 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 solid arrows in fig. 5, by the operation of the blower fan 340, the air outside the machine is taken in the suction duct 350 from the suction port 101 and is sent into the first supply duct 310.

As shown in fig. 2, the air flowing through the first supply duct 310 is heated by the heater 330 to be warm air at a temperature suitable for drying (for example, about 60 ℃). Then, the warm air reaches the first supply port 210, and is discharged from the first supply port 210 into the storage chamber 200. The discharged warm air is diffused through the cover 240 and then goes upward to contact the laundry in a large area, similarly to the ozone-containing air. Thereby, the laundry is dried.

During the drying process, the control part 902 operates the circulation fan 710 in the air circulation unit 700, and swings the ventilation plate 721 in the up-down direction.

As shown in fig. 7 (a), air in the housing room 200 warmed by the supply of warm air is taken into the casing 712 from the intake port 715, and is blown out from the discharge port 716 as warm air. The blown warm air is turned by the swing ventilation plate 721, thereby coming into contact with the laundry from various directions. Thus, the contact efficiency between the warm air and the laundry becomes high, and the laundry is easily dried. Further, by shaking the laundry, warm air can be made to reach a portion of the laundry which is difficult to reach in a stationary state of the laundry, and dust attached to the laundry becomes easy to fall off.

Further, as in the case of the deodorizing operation, even when a plurality of clothes are accommodated in the accommodating chamber 200 as shown in fig. 7 (a), the warm air discharged from the circulation fan 710 and turned by the ventilation plate 721 easily passes through between the clothes and touches the upper portion of the accommodating chamber 200. Thus, the warm air is easily contacted with the plurality of clothes in all directions, and the plurality of clothes are easily dried.

As shown by solid arrows in fig. 6 (a), air stripped of moisture from laundry in the housing chamber 200 is discharged from the discharge port 202. The discharge port 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 removal filter 630. At this time, the ozone removal filter 630 becomes a resistance, and the flow rate of air decreases.

During the drying process, the control unit 902 operates the air mixing unit 800, i.e., the mixing fan 810. As shown by the broken line arrow in fig. 6 (a), the air outside the engine is taken in from the intake port 105 and supplied to a position downstream of the ozone removal filter 630 in the exhaust duct 610 through the introduction duct 820. The air from outside the machine supplied into the exhaust duct 610 is mixed with the air from the housing room 200 passing through the ozone removal filter 630. At this time, since the flow rate of the air from the housing chamber 200 becomes slow, the air from the outside of the machine is easily mixed. By mixing air from outside, the relative humidity of the air from the housing chamber 200 is reduced. As shown by the open arrow in fig. 6 (a), the air having a reduced relative humidity is discharged from the exhaust port 104 to the outside.

When a predetermined drying time elapses, the control unit 902 stops the heater 330, the blower fan 340, the circulation fan 710, the ventilation board 721, and the mixing fan 810, and ends 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 performed (S4). In preparation, the control unit 902 operates the heater 472 of the steam generator 470 in the second supply unit 400 in a state where the pump 461 is stopped. Thereby, the temperature of the main body 471 of the steam generator 470 gradually increases.

Further, during preparation, the control unit 902 causes the circulation fan 710 to operate and causes the ventilation plate 721 to swing in the up-down direction in the air circulation unit 700. As shown in fig. 7 (a), the air in the housing chamber 200 is taken into the casing 712 through the intake port 715 and blown out as wind from the discharge port 716. The blown wind is turned by the swing ventilation plate 721, thereby contacting the laundry from various directions, and shaking the laundry. Thereby, the dust becomes easily dropped from the laundry.

When the temperature of the main body 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 process, the control unit 902 operates the air release shutter 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 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 pipe 410. The released steam rises in the second supply pipe 410 to reach the second supply port 220, and is discharged from the second supply port 220 into the storage chamber 200. The discharged steam collides with the cover 240 and spreads to the surrounding, wherein a part of the steam is discharged from the plurality of discharge holes 244, and the remaining part is discharged from between the cover 240 and the bottom surface of the housing chamber 200. In this way, the steam is diffused through the cover 240 and goes to the laundry upward, contacting the laundry over a large area. The wrinkles of the laundry are smoothed out by the moisture and heat possessed by the steam.

When the steam flows in the second supply duct 410, a part thereof may be condensed to generate dew. The dew condensation water flows downward and is accumulated in the water storage portion 413, and is discharged from the discharge port 414. The discharged dew water is recovered into the drain tank 480 through the drain hose 490. As described above, in the present embodiment, the water storage portion 413 for storing dew condensation water is provided below the inlet 412 of the second supply duct 410, so that dew condensation water is prevented from flowing from the inlet 412 into the steam generator 470.

Further, during the steam process, the circulation fan 710 and the ventilation plate 721 continue to operate. The laundry is shaken by the wind blown out from the discharge port 716 and turned 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. Thus, the surface of the laundry against which the steam hits is easily flattened, and therefore, wrinkles of the laundry become easily flattened. Further, although the laundry is not in a dry state in preparation because it is wetted with steam, dust attached to the laundry can be dropped by shaking the laundry.

Further, as in the case of the deodorizing operation, even when a plurality of clothes are accommodated in the accommodating chamber 200 as shown in fig. 7 (a), the wind which is discharged from the circulation fan 710 and is deflected by the ventilation plate 721 easily passes through between the clothes and touches the upper portion of the accommodating chamber 200. Thus, the wind is easily contacted with the plurality of clothes in all directions, the plurality of clothes are well swayed, and the wrinkles of the clothes are easily flattened.

During the steam process, the exhaust duct 610 is in a closed state. Accordingly, the steam in the housing chamber 200 can be prevented from being discharged to the outside through the exhaust duct 610. Further, in the exhaust duct 610, the ozone removal filter 630 is provided downstream of the exhaust shutter 620, and therefore, it is possible to prevent steam from coming into contact with the ozone removal filter 630 to seriously wet the ozone removal filter 630.

When a predetermined steam supply time elapses, the control unit 902 stops the heater 472 and the pump 461, and ends the steam process.

Next, the control part 902 performs a drying process (S6). The drying process is the same as the drying process in the drying operation, and the blower 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 appropriate for the wrinkle smoothing operation, and may be set to be different from the drying time in the drying operation.

In addition, during the drying process, the control unit 902 operates the air release 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 glance, but opens in stages at a predetermined angle of, for example, 30 degrees each time with the lapse of time. Since the opening amount of the communication port 611 of the exhaust duct 610 gradually increases, the air having high humidity is not discharged from the storage chamber 200 at one time, but is discharged little by little.

Accordingly, since the humidity in the storage compartment 200 is not rapidly lowered, the wrinkle smoothing effect of the laundry can be continued for a while even during the drying process. Further, if air containing a large amount of moisture is discharged from the housing room 200 at a time, the moisture becomes easily attached to the ozone removal filter 630 when the air passes through the ozone removal filter 630. Accordingly, the adhesion of moisture to the ozone removal filter 630 is suppressed by gradually discharging the air containing a large amount of moisture from the housing chamber 200.

Further, the control unit 902 operates the mixing fan 810 in the same manner as the drying operation. Thereby, the air from outside the machine is mixed with the air from the housing room 200, and the air having a reduced relative humidity is discharged from the exhaust port 104 to outside the machine.

When the predetermined drying time elapses and the drying process is finished, the control unit 902 executes the ventilation process (S7). That is, the control part 902 keeps the circulation fan 710 and the ventilation board 721 in operation next to the drying process. Air in the housing chamber 200 is taken in through the intake port 715 and blown out into the housing chamber 200 through the discharge port 716, whereby air outside the housing chamber 200 is taken in through the intake duct 350 and the first supply duct 310 of the first supply unit 300 from the first supply port 210, and air inside the housing chamber 200 is discharged outside the housing chamber through the discharge port 202 and the exhaust duct 610. This ventilates the inside of the storage chamber 200, and the inner wall and the like in the storage 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 housing chamber 200 can be discharged to the outside after the relative humidity is lowered, as in the drying process.

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

In this way, during the wrinkle smoothing operation, the exhaust duct 610 is closed by the exhaust shutter 620 during the steam, and the steam cannot be discharged from the inside of the housing chamber 200 to the outside. As a result, during the wrinkle smoothing operation, the moisture discharged from the laundry treatment apparatus 1 to the outside is reduced, and therefore, the humidity around the laundry treatment apparatus 1 is less likely to be increased.

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

Further, a temperature sensor and a humidity sensor may be disposed in the housing chamber 200. In this case, the drying process may be ended 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 open/close plate 621 may be gradually increased according to the change in the temperature and humidity in the storage chamber 200 during the drying process in the wrinkle smoothing operation.

Effect of the embodiments >

As described above, according to the present embodiment, when warm air is supplied from the first supply unit 300 to dry laundry, 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. Thus, the contact efficiency between the warm air and the laundry becomes high, and the laundry is easily dried. Further, since the laundry is shaken by the warm air from all directions, the warm air can be made to touch a portion of the laundry which is difficult to touch in a stationary state of the laundry, and dust attached to the laundry can be easily dropped.

Further, according to the present embodiment, by operating the air circulation unit 700 when steam is supplied from the second supply unit 400 to steam the laundry to smooth wrinkles of the laundry, the laundry in the storage chamber 200 can be shaken. This makes it easy to flatten the wrinkles of the clothing, and enables dust attached to the clothing to fall off.

Further, according to the present embodiment, when drying laundry, by operating the air mixing unit 800, air from the housing chamber 200 can be mixed with air from the outside in the exhaust duct 610 so that the relative humidity is reduced, and then the air can be discharged to the outside. As a result, the influence of highly humid air such as dew condensation on the wall surface of the room around the laundry treatment device 1 on the periphery of the laundry treatment device 1 due to the discharged air is less likely to occur.

Further, according to the present embodiment, since the exhaust duct 610 is provided with the exhaust shutter 620, the exhaust duct 610 can be closed or opened as needed. In particular, in the course of supplying steam into the housing chamber 200, the exhaust duct 610 is closed by the exhaust shutter 620, so that leakage of steam to the outside can be suppressed. This makes it easier to fill the storage chamber 200 with steam, improves the wrinkle smoothing effect of the laundry, and suppresses the rise of humidity around the laundry treatment apparatus 1. In addition, since the exhaust duct 610 is opened by the exhaust shutter 620 during the drying process of supplying warm air into the storage compartment 200, the warm air, i.e., air from which moisture is peeled off from the laundry, can be discharged to the outside, and the laundry can be dried easily.

Further, according to the present embodiment, when ozone-containing air is supplied from the second supply unit 400 and the laundry is deodorized and sterilized by ozone, the air circulation unit 700 is operated, so that the ozone wind can be brought into contact with the laundry in the storage chamber 200 from various directions. Thus, the contact efficiency between the ozone wind and the clothes becomes good, and the clothes become easy to deodorize and sterilize. Further, the laundry is shaken by the ozone wind from various directions, and therefore, ozone can be made to reach a portion of the laundry which is difficult to reach in a stationary state of the laundry, and dust attached to the laundry is easily dropped.

Further, according to the present embodiment, since the ozone removal filter 630 is provided in the exhaust duct 610, air from which ozone is removed by the ozone removal filter 630 can be discharged to the outside. Further, since ozone removal filter 630 is disposed downstream of exhaust shutter 620, closing exhaust shutter 620 when steam is supplied into housing chamber 200 can prevent ozone removal filter 630 from being wetted with steam, and can prevent ozone removal performance of ozone removal filter 630 from being degraded.

Further, according to the present embodiment, since the air taken in from outside the machine by the operation of the air mixing unit 800 is supplied to the exhaust duct 610 downstream of the ozone removal filter 630, the air outside the machine can be mixed with the air from the housing room 200 having a reduced flow rate due to passing through the ozone removal filter 630. This facilitates mixing of the air outside the machine with the air from the housing room 200, and thus the relative humidity of the air discharged outside the machine is easily reduced.

The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications other than the 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 storage 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, respectively.

In the above embodiment, the inlet 814 of the mixing fan 810 is connected to the inlet 105 of the casing 100. However, the inlet 814 of the mixing fan 810 may be opened into the casing 100 without being connected to the inlet 105. In this case, by the operation of the mixing fan 810, the air outside the machine is taken into the casing 100 through the inlet 105, and the air is taken into the mixing fan 810 from the inside of the casing 100. In this case, the air supplied to the exhaust duct 610 is also referred to as off-board air.

Further, although the air inlet 105 is provided on the rear surface of the casing 100 in the above embodiment, it may be provided on other surfaces of the casing 100, for example, on any one of the left and right side surfaces.

Further, in the above embodiment, the air mixing unit 800 has a structure in which the mixing fan 810 is connected to the exhaust duct 610 via the inlet duct 820. However, the air mixing unit 800 may be configured such that the outlet 815 of the mixing fan 810 is directly connected to the exhaust duct 610. In this case, the suction port 814 of the mixing fan 810 may be directly connected to the suction port 105, may be connected to the suction port 105 via a duct, or may be opened into the casing 100. In addition, the air mixing unit 800 may have any structure as long as it mixes the air outside the machine with the air flowing in the exhaust duct 610.

Further, in the above embodiment, the exhaust duct 610 is opened little by the exhaust shutter 620 with the lapse of time during the drying in the wrinkle smoothing operation, but may be opened at a time.

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 activated carbon/catalyst filter is used for the ozone removal filter 630, but other filters having ozone removal performance such as activated carbon filters may be used.

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

Furthermore, in the above embodiment, the steam generator 470 of the second supply unit 400 has the following structure: the steam is generated by causing water fed from the pump 461 to fall to the bottom surface of the high-temperature steam generation chamber 473 and evaporating it. 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 and boiling the water, for example.

Furthermore, 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 provided at the bottom of the housing chamber 200 and outside the housing chamber 200. In this case, an intake port for taking in air into the circulation fan 710 and an outlet port for blowing out air into the housing room 200 are provided on the wall surface of the housing room 200. The air circulation unit 700 may be disposed at a portion other than the bottom of the housing chamber 200 and on either one of the inner and outer sides of the housing chamber 200.

Further, in the above embodiment, the cross-flow fan is used as the circulation fan 710, but a fan other than a 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 and closing portions may be employed, such as a flap mechanism including a flap (shutter) that moves up and down in the exhaust duct 610 and a driving portion 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 technical proposal.
