Problems to be solved by the invention

Accordingly, an object of the present invention is to provide a laundry treatment apparatus capable of supplying steam to a storage chamber of laundry satisfactorily.

Solution for solving the problem

The laundry treatment apparatus according to the main aspect of the present invention comprises: the first supply port and the second supply port are arranged at the central part of the bottom surface of the accommodating chamber in a mutually adjacent manner; a first supply unit configured to supply warm air and ozone into the housing chamber through a first supply pipe connected to the first supply port; and a second supply unit configured to supply steam into the storage chamber through a second supply pipe connected to the second supply port.

According to the above configuration, the laundry in the storage chamber can be dried by supplying warm air from the first supply unit into the storage chamber, and the laundry in the storage chamber can be deodorized by supplying ozone from the first supply unit into the storage chamber. Further, by supplying steam from the second supply unit into the storage chamber, wrinkles of the laundry in the storage chamber can be smoothed.

Further, since the second supply port and the second supply duct for supplying steam to the storage chamber are provided separately from the first supply port and the second supply duct for supplying warm air and ozone, unlike the conventional structure in which steam is caused to flow through the duct through which ozone and warm air flow and steam is supplied from the duct to the storage chamber, there is no concern that steam flows back to the supply portion of warm air and ozone when it is difficult to discharge steam due to clogging or the like of the outlet of the duct.

Further, since the first supply port and the second supply port are disposed adjacent to each other in the central portion of the housing chamber, the warm air, ozone, and steam can be discharged from the central portion of the bottom surface of the housing chamber into the housing chamber, and the supply of the warm air, ozone, and steam in the housing chamber can be made less likely to be biased to one side.

In the laundry treatment apparatus according to this aspect, the following structure may be adopted: and a cover that covers the first supply port and the second supply port, and that diffuses warm air and ozone discharged from the first supply port around the first supply port, and that diffuses steam discharged from the second supply port around the second supply port.

According to the above configuration, the warm air, ozone, and steam diffuse from the center portion of the bottom surface in the housing chamber to the periphery and flow upward, so that the air is easily and uniformly brought into contact with the clothes. Thus, uneven drying, uneven deodorization, uneven smoothing of wrinkles, and the like can be reduced.

In the case of the above-described configuration, further, a discharge hole may be provided in the cover around the first supply port and the second supply port.

With such a configuration, warm air, ozone, and steam that have diffused around by hitting the cover are discharged from the discharge hole and flow upward in the housing chamber. Thereby, warm air, ozone, and steam are easily diffused and uniformly contacted with laundry. Further, since the discharge hole is not located directly above the first supply port and the second supply port, even if foreign matter enters the discharge hole, the foreign matter is hard to enter the first supply port and the second supply port.

In the case of using the structure including the cover as described above, a gap may be provided between the outer peripheral edge of the cover and the housing chamber.

With such a configuration, warm air, ozone, and steam that have diffused around by hitting the cover are discharged from the gap between the outer peripheral edge of the cover and the housing chamber, and flow upward of the housing chamber. Thereby, warm air, ozone, and steam are easily diffused and uniformly contacted with laundry.

In the case of adopting the structure including the cover as described above, the following structure may be adopted: the first supply port and the second supply port each have an arc-shaped portion that curves in opposite directions from each other when viewed from above.

With this configuration, the first supply port and the second supply port can be formed in a substantially circular shape when viewed from above, and therefore, it is easy to cover both supply ports at a time with the cap.

Inside the door 500, the intake 502 communicates with a plurality of vent holes 501. When the blower fan 340 is operated, external air is taken into the suction duct 350 through the intake 502, the ventilation hole 501, and the suction port 101.

Referring to fig. 3, the second supply unit 400 includes a second supply pipe 410, a steam generating device 420, and a drain device 430. The second supply duct 410 has a shape in which a lower portion bulges rightward. The second supply pipe 410 is provided with a lead-out port 411 connected to an inlet of the second supply port 220 at an upper end portion. The second supply pipe 410 is provided with an inlet 412 on the right side surface of the lower portion. Further, the second supply pipe 410 is provided with a water storage 413 below the inlet 412 at a position where the bottom thereof is lower than the inlet 412.

The steam generating device 420 includes a water supply tank 440, a water supply tank 450, a pump assembly 460, and a steam generator 470. The water supply tank 440 stores water supplied to the steam generator 470. The water supply tank 440 is detachably provided in a water supply tank installation unit, not shown, in the tank 100. When the water supply tank 440 is installed in the water supply tank installation section, the supply port 441 is connected to the inlet 451 of the water supply tank 450 from above. The supply port 441 is provided with an on-off valve 442, and when the supply port 441 is connected to the inlet 451, the on-off valve 442 is opened to supply water from the water supply tank 440 to the water supply tank 450, and the entire water supply tank 450 is filled with water.

The pump assembly 460 includes a pump 461, a connection hose 462, and a water supply hose 463. The suction port of the pump 461 is connected to the outlet 452 of the water supply tank 450 through a connection hose 462. A water supply hose 463 is connected to the discharge port of the pump 461. The pump 461 draws up the water in the water supply tank 450 through the connection hose 462 and sends the water to the steam generator 470 through the water supply hose 463.

The steam generator 470 includes a main body 471 and a heater 472, and is attached to the inlet 412 of the second supply pipe 410 via a heat insulating member, not shown. The main body 471 is formed of a metal material such as aluminum die cast, and has a steam generation chamber 473 therein.

The heater 472 is embedded in the main body 471.

The main body 471 is heated by the heater 472 to be high temperature. The water droplets fed from the pump 461 fall to the bottom surface of the steam generating chamber 473 and evaporate, thereby generating high-temperature steam. The generated steam is discharged into the second supply pipe 410 through the discharge port 475.

The drain 430 includes a drain tank 480 and a drain hose 490. The drain hose 490 has a connection port 491 at an upper end portion thereof, which is connected to the discharge port 414 of the second supply pipe 410. A baffle 492 is disposed on the connection port 491 so as to close the discharge port 414. The baffle 492 is, for example, a mesh plate made of metal and having a fine mesh, and is configured to prevent ozone supplied into the housing chamber 200 from easily leaking into the case 100 through the drain hose 490 during the deodorizing/sterilizing operation.

The drain tank 480 is a container for recovering dew water generated in the second supply pipe 410. The drain tank 480 is detachably provided in a drain tank installation portion, not shown, in the tank 100. When the drain tank 480 is provided at the drain tank installation portion, the inlet 481 thereof is located directly below the lower end of the drain hose 490.

The front surface of the casing 100 is provided with the inlet/outlet 102 of the water supply tank 440 and the drain tank 480 provided in the casing 100 at the front positions of these tanks 440 and 480. The inlet/outlet 102 is covered with an openable/closable cover 103 (see fig. 1). The user can take out and put in the water supply tank 440 and the drain tank 480 into the tank 100 by opening the door 500 and opening the cover 103.

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

In the deodorizing/sterilizing operation, the blower fan 340 and the ozone generator 320 are operated in the first supply unit 300. As shown in fig. 5, the outside air is taken into the intake duct 350 through the intake port 101, and ozone contained in the air is removed by the ozone removal filter 360 in the filter case 351. The ozone-removed air is fed into the first supply duct 310 through the blower fan 340.

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 reaches the first supply port 210 through the first supply duct 310, and is discharged from the first supply port 210 into the housing chamber 200. The discharged ozone-containing air collides with the cover 240 and spreads around, and a part of the air is discharged from the plurality of discharge holes 244 and the rest is discharged from between the cover 240 and the bottom surface of the housing room 200. Thus, the air containing ozone is diffused through the cover 240 and goes upward toward the laundry, and contacts the laundry over a large area. The laundry is deodorized/sterilized by the deodorizing/sterilizing effect of ozone.

The air having the ozone concentration reduced by the deodorization/sterilization of the laundry is discharged to the outside of the cabinet 100 through the ozone removal filter 271 and the exhaust port 202 of the exhaust filtering unit 270 provided at the upper portion of the receiving chamber 200. Ozone in the air is removed by the ozone removal filter 271.

In the drying operation, the blower fan 340 and the heater 330 are operated in the first supply unit 300. As shown in fig. 2, the air taken in by the blower fan 340 and flowing in the first supply duct 310 is heated by the heater 330 to become warm air 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 goes upward toward the laundry, like the air containing ozone, and contacts the laundry in a large area. Thereby, the laundry is dried. The warm air having taken moisture from the laundry is discharged to the outside through the air outlet 202.

In the wrinkle smoothing operation, first, the heater 472 and the pump 461 as the steam generator 470 are operated in the second supply unit 400. 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. This smoothes wrinkles in the clothing by the moisture and heat of 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 pipe 410, so that dew condensation water is prevented from flowing from the inlet 412 into the steam generator 470.

After steam is supplied to the laundry in the storage chamber 200 for a predetermined time, the heater 472 and the pump 461 are stopped. Then, in the first supply unit 300, the blower fan 340 and the heater 330 are operated, and warm air is blown onto the laundry as in the drying operation. Thereby, the laundry wetted with the steam is dried.

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

Effect of the embodiments >

As described above, according to the present embodiment, by supplying warm air from the first supply unit 300 into the storage chamber 200, the laundry in the storage chamber 200 can be dried, and by supplying ozone from the first supply unit 300 into the storage chamber 200, the laundry in the storage chamber 200 can be deodorized and sterilized. Further, by supplying steam from the second supply unit 400 into the storage chamber 200, wrinkles of laundry in the storage chamber 200 can be smoothed.

Further, since the second supply port 220 and the second supply duct 410 for supplying steam to the housing chamber 200 are provided separately from the first supply port 210 and the first supply duct 310 for supplying warm air and ozone, unlike the conventional configuration in which steam is caused to flow through a duct through which ozone and warm air flow and steam is supplied from the duct to the housing chamber, there is no concern that steam flows back to the supply means of warm air and ozone when it is difficult to discharge steam due to clogging or the like of the outlet of the duct.

Further, since the first supply port 210 and the second supply port 220 are disposed adjacent to each other at the central portion in the housing chamber 200, warm air, ozone, and steam can be discharged from the central portion of the bottom surface of the housing chamber 200 into the housing chamber 200, and the supply of warm air, ozone, and steam in the housing chamber 200 can be made less likely to be biased to one side.

Further, a cover 240 is provided in the housing chamber 200, and the cover 240 covers the upper portions of the first supply port 210 and the second supply port 220, so that warm air and ozone discharged from the first supply port 210 are diffused around the first supply port 210, and steam discharged from the second supply port 220 is diffused around the second supply port 220. Accordingly, the warm air, ozone, and steam diffuse from the central portion of the bottom surface to the periphery and flow upward in the housing chamber 200, and thus contact with the laundry is easy and uniform. Thus, uneven drying, uneven deodorization/sterilization, uneven smoothing of wrinkles, and the like can be reduced.

Further, since the cover 240 is provided with the plurality of exhaust holes 244 around the first supply port 210 and the second supply port 220, warm air, ozone, and steam diffused around by hitting the cover 240 are exhausted from the exhaust holes 244 and flow upward in the housing chamber 200. Thereby, warm air, ozone, and steam are easily diffused and uniformly contacted with laundry. Further, since the discharge hole 244 is not located directly above the first and second supply ports 210 and 220, even if foreign matter enters the discharge hole 244, the foreign matter is difficult to enter the first and second supply ports 210 and 220.

Further, since a gap is provided between the outer peripheral edge of the cover 240 and the housing chamber 200, warm air, ozone, and steam diffused to the surroundings by hitting the cover 240 are discharged from the gap between the outer peripheral edge of the cover 240 and the housing chamber 200 and flow upward of the housing chamber 200. Thereby, warm air, ozone, and steam are easily diffused and uniformly contacted with laundry.

Further, the first supply port 210 and the second supply port 220 have arcuate portions 211 and 221, respectively, which are curved in opposite directions from each other when viewed from above. Thus, the shape of the first supply port 210 and the second supply port 220 can be made to be a substantially circular shape when viewed from above, and therefore, it is easy to cover both supply ports 210, 220 at a time with the cover 240.

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

In the above embodiment, the first supply port 210 and the second supply port 220 are formed in a substantially semicircular cylindrical shape having straight portions on both sides. However, the first supply port 210 and the second supply port 220 may have shapes other than the above-described shapes, and may have a cylindrical shape or a square cylindrical shape, for example. Further, as long as the cover 240 can diffuse warm air, ozone, and steam to the surrounding, a structure other than the structure of the above embodiment may be adopted.

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