The structure of the control unit installation unit 313 will be described later.

Figure 6 shows the circulation duct structure of the laundry treatment device of the present invention.

The circulation duct 320 may extend from the base bottom to the top to form a flow path through which air flows. The circulation duct 320 may include a heat exchanger installation portion 3212 that provides a space where the evaporator 341 and the condenser 342 are installed. The heat exchanger installation part 3212 may be provided inside the duct body 321.

The duct body 321 may be provided with an open upper surface. The condenser 343 and the evaporator 341 can be installed through the opening of the duct body 321.

The opening of the duct body 321 may be shielded by the base cover 360, and the base cover 360 and the duct body 321 may form a flow path of the circulation passage 320.

The front surface of the duct body 321 may be arranged to be spaced rearward from the front end of the base bottom portion 311.

As a result, the base bottom portion 311 can secure a support surface 3111 on which one or more of the water tank 3 or the water tank 4 and the outdoor air duct 370 are installed and supported.

Meanwhile, the heat supply unit 340 includes an evaporator 341 installed inside the circulation duct 320 and provided as a heat exchanger to cool and dehumidify the air flowing into the circulation duct 320, and the evaporator 341. A condenser 343 provided as a heat exchanger that heats the passing air to form hot air, and a compressor 342 arranged outside the circulation duct 320 and supplying a refrigerant that exchanges heat with the air to the condenser 343. , It may include an expansion valve 344 that expands and cools the refrigerant that has passed through the condenser 343.

Meanwhile, as the duct body 32 is integrally molded with the base portion 310, the height of the heat exchanger installation portion 3212 can be secured, and the height of the condenser 343 and the evaporator 341 can also be increased. can be increased.

As a result, the width of the condenser 343 and the evaporator 341 in the front and rear directions can be reduced, and the number of refrigerant pipes passing through the condenser and evaporator can be reduced. Accordingly, there is an effect of reducing the flow loss of air passing through the condenser and evaporator.

Meanwhile, the sum of the lengths of the evaporator 341 and the condenser 343 may be smaller than the length of the heat exchanger installation portion 3212. Accordingly, the front-to-back length of the heat exchanger installation portion 3212 may be equal to or less than half the length of the duct body 321.

Therefore, since the heat exchanger installation part 3212 can be sufficiently spaced apart from the outside air intake part 322, sufficient space is provided inside the circulation duct 320 through which the outside air and the air inside the inner case 200 can be introduced. It can be secured.

Additionally, the duct body 321 may be expanded in width based on the installation partition 3211 and extend rearward.

As a result, the width of the heat exchanger installation portion 3212 may be greater than half the width of the base portion 310. Additionally, the width of the circulation duct 320 may be greater than half the width of the base portion 310.

The width of the condenser 343 and the width of the evaporator 341 may also be greater than half the total width of the base portion 310.

As described above, if the width of the condenser 343 and the evaporator 341 is secured, there is an effect of securing sufficient heat exchange capacity.

Additionally, the fan housing 350 may be arranged to overlap the condenser 343 or the evaporator 341 in the front-to-back direction. Accordingly, the air that has passed through the evaporator 341 and the condenser 343 can be introduced into the fan housing 350 without bending the flow path. In other words, the air flowing into the circulation duct 320 has the effect of minimizing flow loss because the flow path is not bent in the process of moving to the fan housing.

The heat exchanger installation part 3212 may be formed between the heat exchanger installation partition 3211 and the air discharge part 323.

The mold for forming the air discharge part 323 may be pulled out in front of the air discharge part 323 and then pulled out to the top and removed. It is necessary to prevent the mold for forming the air discharge part 323 from interfering with the heat exchanger installation partition when the mold for forming the air discharge part 323 is pulled forward from the inside of the air discharge part 323. To this end, the design value of the air discharge unit 323 can be adjusted.

It can be.

That is, in order to prevent the mold pulled out forward from interfering with the heat exchanger installation partition during the pulling process, distance 1 (323a) in the drawing may be made smaller than distance 2 (321c). Distance 1 (323a) may refer to the distance between the parting line of the air discharge unit 323 and the front end of the air discharge unit 323. Additionally, distance 1 (323a) may refer to the distance between the parting line of the air discharge unit 323 and the rear opening of the circulation duct. Distance 2 (321c) may refer to the distance between the front end of the air discharge unit 323 and the partition wall where the heat exchanger is installed. Additionally, distance 2 (323a) may refer to the distance between the rear opening of the circulation duct and the heat exchanger installation partition wall (3211).

When the blowing fan 352 is driven, the air inside the inner case 200 may flow into the first inlet 3621, pass through the blocking filter 366, and be filtered.

When the compressor 342 operates, the air passing through the blocking filter 366 may be dehumidified and heated while passing through the evaporator 341 and the condenser 343.

The air that has passed through the heat exchanger may pass through the fan installation portion 350 and be supplied into the inner case 200.

This state may be a state in which steam is not supplied to the inner case 200. This is because when steam is supplied to the inner case 200, the moisture wets the blocking filter 366 and the performance of the blocking filter 366 cannot be guaranteed.

As a result, even when steam is not supplied to the inner case 200, before steam is supplied inside the inner case 200, or even after steam is supplied inside the inner case 200, the humidity is lowered.

When the blowing fan 352 is driven, air inside the inner case 200 may flow into the third inlet 3622. Since the third inlet 3622 is provided downstream of the blocking filter 366, air flowing into the third inlet 3622 may not pass through the blocking filter 366.

When the compressor 342 operates, the air passing through the blocking filter 366 may be dehumidified and heated while passing through the evaporator 341 and the condenser 343.

The air that has passed through the heat exchanger may pass through the fan installation portion 350 and be supplied into the inner case 200.

As a result, when steam is supplied to the inner case 200 or the humidity inside the inner case 200 is very high, the air of the inner case 200 flows into the third inlet 3622. In addition, the blocking filter 366 can be prevented from being exposed to moisture by blocking the inflow into the first inlet 3621.

Referring to Figure 13(c), the outside air damper 373 opens the outside air intake portion 322, the first damper 3641 shields the first inlet 3621, and the second The damper 3642 can be controlled in a state that shields the third inlet 3622.

When the blowing fan 352 is driven, the air inside the inner case 200 is blocked from flowing into the inlet 362, and only the outside air of the cabinet 100 flows into the circulation duct 320. and can pass through the blocking filter 366. As a result, foreign substances such as fine dust contained in the outside air can be filtered through the blocking filter 366.

When the compressor 342 operates, the air passing through the blocking filter 366 may be dehumidified while passing through the evaporator 341 and the condenser 343.

The air that has passed through the heat exchanger can pass through the fan installation part 350 and be supplied into the inner case 200 to supply fresh hot air to clothes.

At this time, when the door 40 is equipped with a device for discharging the air inside the inner case 200 to the outside, the air outside the cabinet passes through the blocking filter 366 and the heat supply unit 340. It can be discharged in a purified and dehumidified state.

As a result, in the laundry treatment device of the present invention, the control unit (C) controls the external drive unit 374 and the inlet unit 365 to determine the flow direction of the air inside the inner case 200 and the air outside the cabinet. You can.

The heater unit 840 may include a first heater 841 that heats water by receiving first power, and a second heater 842 that heats water by receiving power greater than the first power. .

As a result, the second heater 842 may be equipped to heat a larger amount of water and generate more steam than the first heater 841.

The first heater 841 and the second heater 842 may be provided to divide and consume the maximum amount of heater power allowed for the heater unit 840 in the laundry treatment device. That is, if the first heater 841 is equipped to consume a portion of the maximum heater power amount, the second heater 842 may be equipped to consume the remainder of the maximum heater power amount.

For example, if the general maximum heater power allowable for the heater unit 840 is 1500w, the first heater 841 is provided to consume 600w, and the second heater 842 is provided to consume 880w. It may be provided to do so. 20w can be allocated less considering errors, etc.

Figure 16 shows the laundry treatment apparatus of the present invention installed with a light emitting unit and a sensor unit.

In conventional clothing processing devices, there was a problem with clothing falling off hangers during the clothing processing process.

As a result, there was a problem where the clothes were damaged when the fallen clothes blocked the steam or hot air nozzle because the user was unable to recognize the clothes falling off the hanger during the clothes processing process.

Furthermore, since the user was aware that the clothing was not properly treated because the clothing fell off after the clothing treatment process was completed, the user was unable to take active action, which resulted in lower satisfaction with using the product.

In order to solve the above problem, the present invention includes a cabinet 100 having an opening in the front, an inner case 200 provided inside the cabinet 100 to provide a space for accommodating clothes, and a cabinet 200 coupled to the cabinet and opening the opening. A door 40 that opens and closes, a hanger part 510 provided at the top of the inner case 200 to hold the clothing, and a hanger portion 510 provided below the bottom of the inner case 200 and inside the inner case 200. It is provided in any one of the machine room 300, the inner case 200, the door 40, and the machine room 300, and is provided to supply at least one of hot air and steam, and is located inside the inner case 200. It is provided in any one of the light emitting unit 600, the inner case 200, the door, and the machine room, and the clothing that falls from the hanger 510 is emitted from the light emitting unit 600. A clothing treatment device including a sensor unit 700 that detects at least some blocking of light can be provided.

In the laundry treatment device of the present invention, no matter where the light emitting unit 600 and the sensor unit 700 are provided, as long as the light emitted from the light emitting unit 600 reaches the sensor unit 700, the sensor unit 700 determines the illuminance. Detecting changes can be used to determine whether clothing has fallen.

The clothing treatment device may include a light emitting unit 600 that emits light toward the inside of the inner case 200.

The light emitting unit 600 may be equipped to emit any light as long as the sensor unit 700 can detect it. For example, the wavelength of light emitted from the light emitting unit 600 may be included in the range of ultraviolet rays, visible rays, etc.

It is most preferable that the wavelength of light emitted from the light emitting unit 600 is in the visible light range rather than infrared or ultraviolet rays. Infrared rays can penetrate objects and pass through clothing even if they fall, while visible rays are electromagnetic waves that can be recognized by the human eye and cannot penetrate objects. Additionally, using visible light is more appropriate for detecting clothing drops by blocking light and protects the user's vision.

The light source of the light emitting unit 600 may be anything that emits light, such as an LED or a light bulb.

The clothing treatment device may include a sensor unit 700 that receives light emitted from the light emitting unit 600.

The sensor unit 700 may be provided as an illuminance sensor that detects a change in illuminance of light emitted from the light emitting unit 600. Illuminance is a measure of brightness. When a large amount of light is incident, the illuminance increases, and conversely, when a small amount of light is incident, the illuminance decreases.

The sensor unit 700 can detect at least one of whether light emitted from the light emitting unit 600 is received and the intensity of light.

The sensor unit 700 may be provided in a position where it can fully receive the light emitted from the light emitting unit 600. The specific installation locations of the light emitting unit 600 and the sensor unit 700 will be described later.

The light emitting unit 600 and the sensor unit 700 may each be provided at least one.

When two or more light emitting units 600 are provided, the amount of light received by the sensor unit 700 increases, making it possible to more accurately determine whether clothing has fallen.

The clothing processing device of the present invention can determine whether the clothing has fallen based on a change in the illuminance of light detected by the sensor unit 700 when the clothing falls during the clothing processing process.

For example, the sensor unit 700 is disposed closer to the bottom of the inner case 200 than the hanger unit, and the sensor unit 700 detects the first value when the clothing has not fallen, The control unit C may determine that the clothing has fallen when the sensor unit 700 detects a value smaller than the first value.

Figure 17 shows the spatial area division of the inner case of the laundry treatment device of the present invention.

The inner case 200 may include a first spatial area (V1), a second spatial area (V2), and a third spatial area (V3) divided according to height.

The first spatial area V1 may be defined as the space between the first position (a) and the second position (b).

The second location (b) may be lower than the first location (a) by a first height.

The second position (b) may be separated from the first position (a) by 1/3 of the length from the first position (a) to the fourth position (d).

The height of the first spatial region V1 may be the first height.

The first height may be equal to or greater than the length of the hanger in the height direction.

The first height may be 1/3 of the length from the first position (a) to the fourth position (d).

A hanger unit 510 may be installed in the first spatial area V1.

Clothes that are shorter and smaller than the first height, such as jeogori, baby clothes, and skirts, may be provided in the first spatial area (V1).

The second spatial area (V2) is disposed lower than the first spatial area (V1) and is located between the second position (b) and the third position (c) provided lower than the second position (b). It can be defined as space.

The second spatial area V2 may include a central portion of the inner case 200 in the height direction.

Clothes of relatively general length, such as shirts and jackets, may be provided in the second spatial area V2.

The third spatial area V3 may be disposed lower than the second spatial area V2 and may be defined as a space between the third position (c) and the fourth position (d).

Long clothes, such as coats and pants, can be provided in the third spatial area (V3).

Fallen clothing may be placed in the lower part of the third spatial area (V3).

The light emitting unit 600 and the sensor unit 700 may be provided in at least one of the first spatial area (V1), the second spatial area (V2), and the third spatial area (V3).

The sensor unit 700 may be provided lower than the first position (a).

The sensor unit 700 may be provided above the fourth position (d).

Figure 18 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

The laundry treatment device or control unit (C) of the present invention can determine whether clothing has fallen through the sensor unit 700 detecting an increase in illumination.

When the clothing is hung on the hanger 510, the clothing blocks light emitted from the light emitting portion 600. When clothing falls, the light that was blocked by the clothing reaches the sensor unit 700 due to the falling clothing. As a result, the clothing treatment device or control unit (C) can determine whether clothing has fallen by detecting an increase in illumination.

The light emitting unit 600 and the sensor unit 700 may each be provided as a single unit.

The light emitting unit 600 and the sensor unit 700 may be provided in the same spatial area.

When the light emitting unit 600 and the sensor unit 700 are provided lower than the fifth position (e), the light emitted from the light emitting unit 600 is not blocked from the beginning and is directed to the sensor unit 700. Therefore, the sensor unit 700 cannot detect the change in illuminance.

For example, when the light emitting unit 600 and the sensor unit 700 are provided in the second spatial area (V2) or the third spatial area (V3), short and small clothing is stored in the first spatial area. Since it is provided only in (V1), the sensor unit 700 cannot detect an increase in illumination even if clothes fall.

Therefore, it is preferable that the light emitting unit 600 and the sensor unit 700 are provided at least above the fifth position (e).

The fifth position (e) is provided in at least one of the first spatial area (V1), the second spatial area (V2), and the third spatial area (V3). Even when the fifth position (e) is in the first spatial area (V1), the light emitting unit (600) and the sensor unit (700) are positioned at the upper part of the first spatial area (V1) to detect clothing falling. It is desirable to have it available.

Additionally, the light emitting unit 600 and the sensor unit 700 are preferably provided lower than the hanger unit 510. As a result, the sensor unit 700 can detect changes in light illuminance by minimizing the influence of the hanger unit 510 and using the fact that clothing blocks light emitted from the light emitting unit 600.

Figure 19 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

The sensor unit 700 and the light emitting unit 600 may be provided in different spatial areas. For example, the light emitting unit 600 may be provided in the second spatial area V2 and the sensor unit 700 may be provided in the first spatial area V1.

The light emitting unit 600 may be provided toward the sensor unit 700 so that the sensor unit 700 can detect light. The light emitting unit 600 may be provided to emit light into an area where the sensor unit 700 can detect light.

The light emitting unit 600 and the sensor unit 700 may be provided on surfaces of the inner case 200 facing each other.

The light emitting unit 600 may be provided so that light emitted from the light emitting unit 600 passes through the first spatial region V1. Accordingly, even when short clothing is hanging, the sensor unit 700 can detect an increase in light illuminance by utilizing the fact that the clothing blocks the light emitted from the light emitting unit 600.

A reflecting unit 400, etc. may be additionally installed to guide the light emitted from the light emitting unit 600 to the sensor unit 700 provided in another spatial area.

Figure 20 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

The light emitting unit 600 and the sensor unit 700 may each be provided at least one.

The number of light emitting units 600 and sensor units 700 may not be the same, and when two or more light emitting units 600 are provided, two or more sensor units 700 may also be provided.

Even when two or more light emitting units 600 are provided, only one sensor unit 700 may be provided.

Two or more light emitting units 600 may be provided in different spatial areas. For example, the light emitting unit 600 includes the first light emitting unit 610 provided in the first spatial area (V1) and the second light emitting unit 620 provided in the second spatial area (V2). More may be included.

The first light emitting unit 610 and the second light emitting unit 620 may be provided on one surface of the inner case 200.

The first light emitting unit 610 and the second light emitting unit 620 may be provided side by side in the height direction of one surface of the inner case 200.

The sensor unit 700 may be provided on a surface opposite to the surface provided with the light emitting unit 600 so as to face at least one of the first light emitting unit 610 or the second light emitting unit 620.

The light emitted from the first light emitting unit 610 passes through the first spatial area (V1) and the second spatial area (V2) and reaches the sensor unit 700. It may be provided to do so.

The second light emitting unit 620 may be provided so that light emitted from the second light emitting unit 620 passes through the second spatial area V2 and reaches the sensor unit 700.

Accordingly, the clothing treatment device or the control unit (C) can detect the fall of clothing provided in the first spatial area (V1) by using blocking the light emitted from the first light emitting unit (610), and emit the second light. Falling of clothing provided in the second spatial area V2 can be detected by blocking the light emitted from the unit 620.

Accordingly, regardless of where the fifth position (e) is located, the sensor unit 700 can determine whether clothing has fallen by detecting a change in light intensity.

In addition, since the sensor unit 700 receives the light emitted from the light emitting unit 600 all at once, the laundry treatment device or the control unit C can easily control the sensor unit 700 at once.

Figure 21 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

Meanwhile, clothing is hung on the hanger unit 510 provided in the first spatial area V1 from one side of the inner case 200 in a direction opposite to the one side.

The light emitting unit 600 and the sensor unit 700 may be provided on both sides of the inner case 200, respectively. However, in the case where multiple pieces of clothing are provided, even if the clothing falls, the light emitted from the light emitting unit 600 is fundamentally blocked by the clothing provided in front of the fallen clothing, and the sensor unit 700 detects changes in illuminance. It may not be detectable.

Accordingly, the light emitting unit 600 and the sensor unit 700 may be provided on at least one of the rear of the inner case 200 or the door.

The light emitting unit 600 may be provided on the door so that the light emitted from the light emitting unit 600 is directed toward the inside of the inner case 200.

The sensor unit 700 may be provided on the rear of the inner case 200 to face the light emitting unit 600.

Unlike the above description, the light emitting unit 600 may be provided on the rear of the inner case 200, and the sensor unit 700 may be provided on the door.

The light emitting unit 600 and the sensor unit 700 may be provided on the same line as the width direction of the clothing hanging on the hanger unit 510. Additionally, the light emitting unit 600 may be provided to emit light toward the side of clothing hanging on the hanger unit 510. Therefore, if the clothing does not fall, the clothing hanging on the hanger 510 may block the light emitted from the light emitting unit 600.

The light emitting unit 600 and the sensor unit 700 may be provided as many as the hanger units 510. For example, if there are five hanger units 510, there may also be five light emitting units 600 and sensor units 700.

The light emitting unit 600 may further include a first light emitting unit 610, a second light emitting unit 620, a third light emitting unit 630, a fourth light emitting unit 640, and a fifth light emitting unit 650. You can.

The distance between the first light emitting unit 610, the second light emitting unit 620, the third light emitting unit 630, the fourth light emitting unit 640, and the fifth light emitting unit 650 is between the hanger units 510. It can be provided in a row with the same spacing.

The sensor unit 700 may further include a first sensor unit 710, a second sensor unit 720, a third sensor unit 730, a fourth sensor unit 740, and a fifth sensor unit 750. You can.

The distance between the first sensor unit 710, the second sensor unit 620, the third sensor unit 730, the fourth sensor unit 740, and the fifth sensor unit 750 is between the hanger units 510. It can be provided the same as the spacing.

That is, the gap between the first sensor unit 710, the second sensor unit 720, the third sensor unit 730, the fourth sensor unit 740, and the fifth sensor unit 750 is the first light emitting unit. The light emitting units 610, the second light emitting unit 620, the third light emitting unit 630, the fourth light emitting unit 640, and the fifth light emitting unit 650 may be arranged in a row at the same interval as the interval between them.

The first sensor unit 710, the second sensor unit 720, the third sensor unit 730, the fourth sensor unit 740, and the fifth sensor unit 750 are each connected to the first light emitting unit 610. , it is provided to face the second light emitting unit 620, the third light emitting unit 630, the fourth light emitting unit 640, and the fifth light emitting unit 650.

If the clothing between the first light emitting unit 610 and the first sensor unit 710 falls, the light emitted from the first light emitting unit 610 by the clothing is transmitted to the first sensor unit 710. reaches , so that the first sensor unit 710 can detect an increase in the illuminance of light.

The light emitting unit 600 and the sensor unit 700 may be provided in any one of the first spatial area (V1), the second spatial area (V2), or the third spatial area (V3).

If the fifth position (e) is above the sensor unit 700, the clothing may not be able to block the light emitted from the light emitting unit 600, so it may not be possible to determine whether the clothing has fallen. Therefore, it is most preferable that the light emitting unit 600 and the sensor unit 700 are provided in the first spatial area V1.

When at least one piece of clothing hanging on the hanger unit 510 falls, the sensor unit 700 detects light emitted from the light emitting unit 600 provided on the same line as the clothing. As a result, the clothing treatment device or the control unit C can detect an increase in the illuminance of light emitted from the light emitting unit 600.

Accordingly, even when there are multiple pieces of clothing, the clothing handling device can determine not only whether the clothing has fallen but also which clothing has fallen through the sensor unit 700 detecting an increase in light intensity.

Figure 22 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

The clothing treatment device or the control unit (C) may determine whether the clothing has fallen through the sensor unit 700 detecting a decrease in illumination. When clothing falls, the fallen clothing blocks the light emitted from the light emitting unit 600. Therefore, since the light emitted from the light emitting unit 600 does not reach the sensor unit 700, the sensor unit 700 can detect an abnormal decrease in illuminance.

That is, the sensor unit 700 is disposed closer to the bottom surface of the inner case 200 than the hanger unit, the sensor unit 700 detects the first value when the clothing does not fall, and the control unit (C) When the sensor unit 700 detects a value smaller than the first value, it can be determined that the clothing has fallen.

The light emitting unit 600 and the sensor unit 700 may be arranged in the width direction or front-to-back direction based on the bottom surface of the inner case 200. As a result, the light emitted from the light emitting unit 600 may be partially blocked by the clothing that has fallen on the bottom of the inner case 200.

For example, the sensor unit 700 is disposed at the rear of the inner case 200, and the light emitting unit 600 is disposed in front of the sensor unit 700, or the sensor unit 700 is disposed at the rear of the inner case 200. It may be placed on one side of the inner case 200, and the light emitting unit 600 may be placed on a side of the sensor unit 700.

The sensor unit 700 and the light emitting unit 600 may be provided on different sides of the inner case 200.

The sensor unit 700 may be provided on a surface opposite to the surface where the light emitting unit 600 is provided.

At this time, since the light emitted from the light emitting unit 600 should not reach the sensor unit 700 due to fallen clothing, it is preferable that the light emitting unit 600 and the sensor unit 700 are provided to face each other. do.

For example, the light emitting unit 600 and the sensor unit 700 may be provided to face each other on both sides of the inner case 200.

Alternatively, the light emitting unit 600 and the sensor unit 700 may be provided to face at least one of the back of the inner case 200 or the door, respectively.

This shows an embodiment of the laundry treatment apparatus of the present invention in which the light emitting unit 600 is provided on the door and the sensor unit 700 is provided on the rear of the inner case 200.

The light emitting unit 600 may be disposed in the middle of the door in the width direction. As a result, no matter where the sensor unit 700 is installed, the non-detectable area can be reduced to detect fallen clothing no matter where it falls, and more light emitted from the light emitting unit 600 can be received. can do.

The light emitting unit 600 and the sensor unit 700 may be provided in the same spatial area. For example, the light emitting unit 600 and the sensor unit 700 may be provided in the third spatial area V3. When clothing falls, the clothing is located in the third spatial area (V3), so it is preferable that the light emitting unit 600 and the sensor unit 700 are provided in the third spatial area (V3).

The light emitting unit 600 and the sensor unit 700 may be disposed lower than the hanger unit 510. The light emitting unit 600 and the sensor unit 700 may be provided below the lowest height (e) of the clothing. That is, the light emitting unit 600 and the sensor unit 700 may be disposed closer to the bottom surface of the inner case 200 than the hanger unit 510. Accordingly, the clothing handling device or the control unit (C) can determine whether the clothing has fallen by minimizing the influence of the clothing hanging on top.

Accordingly, when the sensor unit 700 detects a decrease in light intensity caused by fallen clothing and determines whether the clothing has fallen, it is not affected by the length of the clothing, but only uses the decrease in light intensity blocked by the fallen clothing. It is possible to determine whether clothing has fallen.

Additionally, when the sensor unit 700 determines whether clothing has fallen by detecting a decrease in light illuminance caused by fallen clothing, it is possible to more easily and accurately determine whether clothing has fallen even when multiple clothing items are provided.

In addition, material costs, etc. can be reduced by using the light emitting unit 600 and the sensor unit 700 to a minimum.

Figure 23 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

The light emitting unit 600 and the sensor unit 700 may be provided to face at least one of the upper or lower part of the inner case 200, respectively.

The light emitting unit 600 may be provided on the upper surface of the inner case 200.

The light emitting unit 600 may be provided below the hanger unit 510.

The sensor unit 700 may be provided on the bottom of the inner case 200 so that the sensor unit 700 is obscured by clothing when the clothing falls.

Alternatively, the sensor unit 700 may be provided inside the machine room or in the inlet body. This can be advantageous for repairs and power supply.

Unlike the above description, the light emitting unit 600 may be provided at the lower part of the inner case 200, and the sensor unit 700 may be provided at the upper part of the inner case 200. In this case, the light emitting unit 600 may be provided in the machine room or in the inlet body.

The light emitting unit 600 and the sensor unit 700 may be provided to face each other in a straight line.

Specifically, when clothing falls, the sensor unit 700 is covered and light emitted from the light emitting unit 600 is blocked. As a result, the sensor unit 700 detects a decrease in light intensity, so that the clothing treatment device or the control unit (C) can determine whether the clothing has fallen.

At least one of the light emitting unit 600 and the sensor unit 700 may be provided. In particular, the more sensor units 700 there are, the more desirable it is. In most cases, when clothing falls, it falls around the area where it was hung due to gravity, so if multiple sensor units 700 are provided, the sensor units 700 can more accurately determine whether the clothing has fallen.

For example, three sensor units 700 may be provided on the bottom of the inner case 200. The sensor unit 700 may include a first sensor unit 710, a second sensor unit 720, and a third sensor unit 730.

The first sensor unit 710, second sensor unit 720, and third sensor unit 730 may be provided in a row.

At least one of the first sensor unit 710, the second sensor unit 720, and the third sensor unit 730 may be provided to face the light emitting unit 600.

When clothing falls, the clothing falls on top of at least one of the first sensor unit 710, the second sensor unit 720, and the third sensor unit 730. At least one of the unit 720 and the third sensor unit 730 may be covered.

Accordingly, at least one of the first sensor unit 710, the second sensor unit 720, and the third sensor unit 730 detects a decrease in light illuminance, thereby controlling the laundry treatment device or the control unit (C). can determine whether clothing has fallen.

In addition, it is possible to determine whether clothing has fallen by only using the decrease in illuminance of light blocked by the fallen clothing, without being affected by the length or number of clothing.

Figure 24 shows an embodiment of the reflecting part of the laundry treatment apparatus of the present invention.

Meanwhile, when the light emitting unit 600 and the sensor unit 700 are provided to face each other, the light emitted from the light emitting unit 600 travels straight and reaches the sensor unit 700. Therefore, when clothing falls in an area other than the area where the light emitted from the light emitting unit 600 travels straight, the sensor unit 700 may not detect a change in illuminance because the light is not blocked by the clothing.

The laundry treatment device has a first falling area (S1) provided between the light emitting unit 600 and the sensor unit 700 and an undetectable area (X) defined as an area other than the first falling area (S1). may include.

If clothing falls into the first falling area (S1), the fallen clothing blocks the light emitted from the light emitting unit 600 and the sensor unit 700 can detect a decrease in illumination, but the clothing cannot be detected. If the clothes fall in the area, the fallen clothing cannot block the light emitted from the light emitting unit 600, so the sensor unit 700 cannot detect a decrease in illumination.

However, if the fallen clothing touches the first falling area (S1) even slightly, the light emitted from the light emitting unit 600 is blocked by a portion of the clothing, so the sensor unit 700 detects a decrease in illumination. can do.

In order to minimize the non-detectable area (X) and determine whether the clothing has fallen regardless of where the clothing falls, the clothing handling device may further include a reflector 400.

The reflector 400 may be comprised of at least one reflector.

The reflector may be provided on a side different from the side on which the light emitting unit 600 and the sensor unit 700 are provided.

The reflector 400 includes a first reflector 410 provided on a side of the inner case 200 and a second reflector 420 provided on a side opposite to the side provided with the first reflector 410. It can be included.

The first reflector 410 and the second reflector 420 may be provided at the center of one side of the inner case 200 in the width direction. As a result, the second falling area (S2) and the third falling area (S3) can be expanded to reduce the non-detection area.

The first reflector 410 and the second reflector 420 may be provided to face each other.

The first reflector 410 and the second reflector 420 may be provided at the center of one side of the inner case 200 in the width direction.

The clothing treatment device includes a second falling area (S2) formed by light reflected by the first reflecting plate (410) and a third falling area (S3) formed by light reflected by the second reflecting plate (420). It may further include.

When the reflector 400 is provided, the area of the non-detectable area is reduced compared to when the reflector 400 is not provided. When clothing falls and a portion of the clothing falls over any one of the first fall zone (S1), second fall zone (S2), and third fall zone (S3), the light emitted from the light emitting unit 600 falls. The sensor unit 700 can detect a decrease in illumination due to being blocked by the clothing.

Accordingly, the clothing handling device can determine whether the clothing has fallen no matter which area of the bottom surface of the inner case 200 by minimizing the non-detectable area (X).

Figure 25 shows the filter unit of the laundry treatment device of the present invention.

The clothing treatment device 1 may include a filter unit 380 at the top of the machine room 300 to prevent dust from entering the circulation duct 320.

The filter unit 380 may be mounted on the inlet body 361 to filter dust flowing into the inlet body 361.

The filter unit 380 may include a body filter 386 that is mounted on the upper part of the inlet body 361 of the base cover 360 and is provided to shield a portion of the upper surface of the inlet body 361. . The body filter 386 can block large dust and may be made of a mesh material that allows light to pass through.

The filter unit 380 may further include a body cover 385 on which the body filter 386 is seated. The body cover 385 may be provided on top of the inlet body. The body cover 385 may shield one surface of the upper part of the first inlet 3621 and the third inlet 3622. The portion of the body cover 385 that shields the upper surfaces of the first inlet 3621 and the third inlet 3622 may be provided with a perforation. The body cover 385 can prevent dust from entering the circulation duct 320 by blocking large dust, such as when the body filter 386 is not installed.

The filter unit 380 may further include a filter fixing unit 384 to fix the body cover 385 and the body filter 386. The filter fixing part 384 may be provided on the top of the base cover 360. The peripheral surface of the body cover 385 may be coupled to the filter fixing part 384 and may be detached from the filter fixing part 384. The filter fixing part 384 can shield one side of the machine room 300 and the drawer (5).

The clothing treatment device may further include a filter cover 382 on top of the body cover 385. The filter cover 382 may be provided larger than the width of the body cover 385. The filter cover 382 may shield one side of the body filter 386. The lower surface of the filter cover 382 may be formed of a grid-shaped injection molded product. The filter cover 382 may be provided to be spaced apart from the bottom surface of the inner case 200 to allow air inside the inner case 200 to flow into the circulation duct 320.

A blocking cover 381 may be provided on the filter cover 382. The blocking cover 381 can completely shield the open upper surface of the machine room 300.

Figure 26 shows an example of the positions of the light emitting unit and the sensor unit of the laundry treatment apparatus of the present invention.

The light emitting unit 600 and the sensor unit 700 may be installed in any position as long as the sensor unit 700 does not detect light emitted from the light emitting unit 600 by fallen clothing.

Therefore, it is preferable that the light emitting unit 600 and the sensor unit 700 are provided lower than the hanger unit 510. A lower part than the hanger part 510 includes the second spatial area V2, the third spatial area V3, and the machine room 300 within the inner case 200.

Accordingly, one of the light emitting unit 600 and the sensor unit 700 is disposed inside the machine room, and the other one of the light emitting unit 600 and the sensor unit 700 is located inside the inner case 200 or It may be placed on the door 40.

The light emitting unit 600 may be provided lower than the inner case 200, particularly inside the machine room 300. As a result, power supply and repair can be advantageous, and the influence of clothing hanging inside the inner case 200 can be minimized when determining whether clothing has fallen.

The light emitting unit 600 may be provided toward the sensor unit 700 so that the light emitted from the light emitting unit 600 is received by the sensor unit 700. At this time, the filter cover 382 may not be provided.

When clothing falls, the clothing exists in the third spatial area (V3), and the sensor unit 700 detects that light is blocked by the fallen clothing, so the sensor unit 700 detects that the inner case 200 It may be provided in the lower part of , that is, in the third spatial area (V3).

In order for the sensor unit 700 to detect light emitted from the light emitting unit 600 disposed inside the machine room 300, the light emitting unit 600 and the sensor unit 700 are connected to the inner case 200. It is desirable to arrange them in the width direction or front-to-back direction based on the floor surface.

That is, part of the path of light emitted from the light emitting unit 600 must pass parallel to the bottom surface of the inner case 300 in the width direction or front-to-back direction.

Accordingly, the sensor unit 700 is disposed at the rear of the inner case 200, and the light emitting unit 600 is disposed in front of the sensor unit 700, or the sensor unit 700 is disposed at the rear of the inner case 200. It is disposed on one side of 200, and the light emitting unit 600 may be disposed on a side of the sensor unit 700.

Since there is a high possibility that clothing will fall on the rear of the inner case 200 when clothing falls, it is preferable that the light emitted from the light emitting unit 600 is provided to cross along the front and rear direction of the inner case 200. .

For example, the light emitted from the light emitting unit 600 may be directed toward the rear of the inner case 200. Accordingly, it is preferable that the sensor unit 700 is also provided at the rear of the inner case 200 so that it faces the inside of the inner case 200.

When clothing falls, the fallen clothing blocks the light emitted from the light emitting unit 600. Accordingly, the sensor unit 700 detects an abnormal decrease in illumination, and the clothing treatment device or the control unit C can determine whether the clothing has fallen.

The light emitting unit 600 may be provided at a front edge or rear edge of the body cover 385 in a dead portion relative to the body filter 386.

The light emitting unit 600 may be provided lower than the body filter 386 even inside the machine room. As a result, the performance of the light emitting unit 600 can be prevented from being deteriorated due to dust filtered in the body filter 386, and light can be prevented from being exposed to the user's eyes.

The light emitting unit 600 and the sensor unit 700 may be provided with the body filter 386 interposed therebetween. Accordingly, the light emitting unit 600 is provided so that the light emitted from the light emitting unit 600 penetrates the body filter 386 and can be detected by the sensor unit 700.

The light emitting unit 600 may be provided on one side of the inlet body 361. The light emitting unit 600 may be provided at the front or rear edge of the inlet body 361 to emit light to the upper part of the inlet body 361. That is, the light emitting unit 600 may be provided to emit light toward the top of the first inlet 3621 or the third inlet 3622. A shielding member that shields the second inlet 3623 may be further coupled to the second inlet 3623 of the inflow body 361. Accordingly, it cannot be provided to emit light above the second inlet 3623, so it is preferable to be provided at the front or rear rather than the side of the inlet body 361.

The light emitting unit 600 may further include a lighting installation unit capable of installing a light source. The lighting installation unit may be provided through the front or rear of the inlet body.

The light emitting unit 600 is provided below the body filter 386, so that the clothes treatment device or the control unit (C) detects the change in illuminance of the light emitted from the light emitting unit 600 at the sensor unit 700. Using this, it is possible to determine not only whether clothing has fallen, but also whether the body filter 386 is attached or detached or the degree of contamination of the body filter 386.

Meanwhile, the machine room 300 may be located to the left of the laundry treatment device. The width direction center of the machine room 300 may not be the same as the width direction center of the laundry treatment device. The width direction center of the laundry treatment device may be located on the right side of the machine room 300.

Accordingly, the light emitting unit 600 may be provided on the same line as the center of the width direction of the laundry treatment device, rather than the center of the machine room 300 in the width direction.

The sensor unit 700 may be provided at the center of the rear surface of the inner case 200 in the width direction. Accordingly, the sensor unit 700 and the light emitting unit 600 can be provided in a straight line at the center of the inner case 200 in the width direction.

That is, the sensor unit 700 is provided at the center of the rear surface of the inner case in the width direction, the inflow body 361 is disposed to be biased to one side on the bottom surface of the inner case, and the light emitting unit 600 is the It may be placed at a position corresponding to the sensor unit 700 inside the inflow body 361.

Unlike the above description, the positions of the light emitting unit 600 and the sensor unit 700 may be exchanged.

The light emitting unit 600 and the sensor unit 700 may be provided as one unit. As a result, the clothing treatment device can reduce material and manufacturing costs and can efficiently detect whether clothing has fallen using a single sensor unit 700.

Meanwhile, when the light emitting unit 600 is provided below the body filter 386, the angle of light emitted from the light emitting unit 600 and the step between the body cover 385 and the inner case 200 Therefore, light cannot reach the sensor unit 700 provided at the rear of the inner case 200.

In order for the sensor unit 700 to detect a change in illuminance of light emitted from the light emitting unit 600, the light emitted by the light emitting unit 600 is guided toward the lower part of the inner case 200 and finally reaches the sensor. You must reach wealth (700).

Therefore, when the light emitting unit 600 is provided inside the machine room 300, the light emitted from the light emitting unit 600 is guided to the sensor unit 700 and the illuminance required for detection is secured. It may further include a reflection unit 400 disposed above the light emitting unit 600 to guide the light emitted from the light emitting unit 600 to the sensor unit 700.

The reflector 400 may be provided in a position, angle, and number so that the sensor unit 700 can detect the light emitted from the light emitter 600 by reflecting it.

The reflector 400 may be provided to reflect light emitted from the light emitter 600 and guide it to the sensor unit 700, regardless of where the light emitter 600 and the sensor unit 700 are installed. .

The reflecting unit 400 may be provided above the light emitting unit 600 and arranged in a straight line with the light emitting unit 600. The light emitted from the light emitting unit 600 may be provided to directly reach the reflecting unit 400.

The reflecting unit 400 may be provided between the light emitting unit 600 and the sensor unit 700.

The reflection unit 400 may be provided above the body filter 386 and disposed between the body filter 366 and the light emitting unit 600. The reflector 400 may be provided on one side of the body cover 385. As a result, the light emitted from the light emitting unit 600 is guided to the reflecting unit 400 and even the level of contamination in the local area of the body filter 386 can be detected.

The reflector 400 may be disposed between the filter cover 382 and the body filter 386. The reflector 400 may be provided on the lower surface of the filter cover 382. The step between the body cover 385 and the bottom surface of the inner case 200 is overcome, and the light emitted from the light emitting unit 600 is transmitted from the reflecting unit 400 to the rear surface of the inner case 200. In order to guide the sensor unit 700, it is preferably provided on the lower surface of the filter cover 382.

When the reflector 400 is provided below the filter cover 382, the filter cover 382 includes a reflector 400 for installing the reflector 400 on the lower surface of the filter cover 382. It may further include an installation part. The detailed structure of the filter cover 382 will be described later.

As a result, the light emitted from the light emitting unit 600 is guided to the sensor unit 700 in the space spaced apart between the filter cover 382 and the bottom surface of the inner case 200, and the sensor unit 700 A decrease in illumination caused by dropped clothing can be detected.

Figure 27 shows the structure of the first reflector.

The reflector 400 may include a first reflector 410 provided on the same line in the height direction as the light emitter 600.

The first reflector 410 may be provided on the lower surface of the filter cover 382.

The first reflector 410 may be provided at the center of the filter cover 382 in the width direction.

The light emitting unit 600, the sensor unit 700, and the first reflector 410 are arranged in a straight line, and the light emitted from the light emitting unit 600 is sent directly to the sensor. A first reflective surface 411 may be provided to reflect the unit 700.

The first reflective surface 411 may be provided toward the rear of the laundry treatment device.

The first reflector 410 may be provided with a hook 3823 that can be coupled to the filter cover 382.

The laundry treatment device may further include a first path (R1) through which light emitted from the light emitting unit 600 is guided to the sensor unit 700 through the first reflecting surface 411.

The first path R1 may pass through the lower part of the inner case 200. The first path R1 may pass close to the bottom surface of the inner case 200.

When clothing falls, the fallen clothing blocks the light passing through the first path (R1). Accordingly, the sensor unit 700 detects an abnormal decrease in illumination, and the clothing treatment device or the control unit C can determine whether the clothing has fallen.

Figure 28 shows an embodiment of the reflecting part of the laundry treatment apparatus of the present invention.

Figure 28(a) shows an exploded perspective view of the filter unit 380, and Figure 28(b) shows a cross-section of the machine room cut in the horizontal direction.

There may be cases where the first reflector 410 alone cannot sufficiently transmit the light emitted from the light emitting unit 600 to the sensor unit 700.

Therefore, as shown in FIG. 28(a), the reflector 400 is symmetrical on both sides of the first reflector 410 in order to sufficiently transmit the light emitted from the light emitter 600 to the sensor unit 700. It may further include a second reflector 420 and a third reflector 430.

The second reflector 420 and the third reflector 430 may be provided on the lower surface of the filter cover 382 close to both edges of the filter cover 382.

At this time, the first reflector 410 is a second reflective surface 412 that reflects the light reflected from the light emitting unit 600 to the second reflector 420, and the light reflected from the light emitting unit 600 It may further include a third reflection surface 413 that reflects the third reflection plate 430.

Additionally, the second reflection plate 420 may include a fourth reflection surface 421 that reflects light reflected from the second reflection surface 412 toward the sensor unit 700. The third reflection plate 430 may be provided with a fifth reflection surface 431 that reflects light reflected from the third reflection surface 413. Accordingly, the light reflected from the fourth and fifth reflection surfaces 421 and 431 can be detected by the sensor unit 700.

That is, the first reflector 410 can reflect the light emitted from the light emitting unit 600 to the second reflector 420 and the third reflector 430. Light reflected by the second reflector 420 and the third reflector 430 can be detected by the sensor unit 700.

The clothes treatment device is such that the light emitted from the light emitting unit 600 reflects the second reflecting surface 412 of the first reflecting plate 410 and the fourth reflecting surface 421 of the second reflecting plate 420. It may further include a second path (R2) leading to the sensor unit 700.

The clothes treatment device is such that the light emitted from the light emitting unit 600 reflects the third reflective surface 413 of the first reflective plate 410 and the fifth reflective surface 431 of the third reflective plate 430. It may further include a third path (R3) leading to the sensor unit 700.

When the clothing falls, the fallen clothing blocks light passing through the second path and the third path. Accordingly, the sensor unit detects an abnormal decrease in illumination, and the clothing treatment device or the control unit (C) can determine whether the clothing has fallen.

In addition, the light emitted from the light emitting unit 600 is guided to the first, second, and third paths (R1, R2, and R3), so that the degree of contamination in the local area of the body filter 386 can be detected.

Figure 29 shows an embodiment of the reflecting part of the laundry treatment apparatus of the present invention.

As shown in Figure 28, when the reflector 400 includes the first reflector 410, the second reflector 420, and the third reflector 430, the clothing falls and travels through the first path (R1). ), when at least one of the second path (R2) or the third path (R3) is blocked, the sensor unit 700 emits about 0 to 66% of the light emitted from the light emitting unit 600. It can be detected. However, when the body filter 386 is installed and the clothing has not fallen, the sensor unit 700 can detect about 60 to 70% of the light emitted from the light emitting unit 600. Therefore, there is an overlapping range of the amount of light detected by the sensor unit 700 when the clothing falls and when the clothing does not fall, and if about 66% or less of light is detected, it cannot be detected. There is a possibility that the accuracy of determining whether clothing has fallen may decrease.

Accordingly, in order to eliminate the overlapping range, the clothing treatment apparatus has the light emitting unit 600 provided at the lower part of the body filter 386, and the sensor unit 700 installed at the inner case 200 or the door ( 40) and disposed closer to the filter unit 380 than the hanger unit 510, the reflector 400 reflects the second reflector 420 and the first reflector excluding the first reflector 410. 3 It may be provided to include only the reflector 430.

The second reflector 420 and the third reflector 430 are provided so that the light emitted from the light emitting unit 600 passes through the body filter 386 and passes through the second path (R2) and the third path ( You can pass through R3).

If the clothing falls on the bottom of the inner case 200, the clothing may block at least one of the second path (R2) or the third path (R3).

Accordingly, the control unit C can determine whether the clothing has fallen through a change in the illuminance of the light emitted by the sensor unit 700 from the light emitting unit 600.

Specifically, when the body filter 386 is installed and the clothing has not fallen, the sensor unit 700 can detect about 60 to 70% of the light emitted from the light emitting unit 600. At this time, when the clothing falls and blocks at least one of the second path (R2) or the third path (R3), approximately 0 to 50% can be detected.

As a result, the overlapping range of the amount of light detected by the sensor unit 700 when the clothing falls and when the clothing does not fall is eliminated, and the second reflector disposed on both sides of the filter cover 382 ( 420) and the third reflector 430 alone, the control unit C can accurately determine whether clothing has fallen and whether the body filter 386 is attached or detached.

Figure 30 shows the clothing falling area of the clothing processing device of the present invention.

Meanwhile, when the light emitting unit 600 is installed in the machine room or lower part of the body filter, the light emitted by the light emitting unit 600 is emitted to the rear of the inner case 200 and is thus transmitted to the filter cover 382. There may be an area that is obscured and cannot be detected by the sensor unit 700, that is, a non-detection area (X). If clothing falls in the non-detectable area (X), the fallen clothing cannot block the light emitted from the light emitting unit 600, so the sensor unit 700 cannot detect a decrease in illumination.

Therefore, the light emitted from the light emitting unit 600 is dispersed in at least two directions so that the sensor unit 700 blocks the light emitted from the light emitting unit 600 by clothing that has fallen to the floor. It may further include a reflector 400 provided for sensing.

As shown in FIG. 30(a), clothing falls to the rear of the inner case 200, or the area of the falling clothing is larger than the non-detectable area (X), making it more likely that it will fall only in a part of the non-detectable area (X). Because it is high, even when the light emitting unit 600 is installed in the machine room 300 or below the body filter 366, the sensor unit 700 can detect a change in the illuminance of the light emitted from the light emitting unit 600. You can.

However, as shown in Figure 30(b), when very small clothing such as a scarf falls or falls in front of the inner case 200, the area of the falling clothing is narrower than the non-detectable area (X), so the non-detectable area ( It can fall on X).

Therefore, as shown in FIG. 30(c), in order to minimize the non-detectable area (X) of the sensor unit 700, the reflection unit 400 It may be disposed on both sides of the unit 700 and the light emitting unit 600.

The second reflector 420 and the third reflector 430 may be placed close to both edges of the filter cover 382. In addition, the second reflector 420 and the third reflector 430 may be placed close to the rear edge of the filter cover 382 to minimize the non-detection area (X) of the sensor unit 700. .

Accordingly, the second reflector 420 and the third reflector 430 can be placed as close to both sides and rear edges of the filter cover 382 as possible to minimize the non-detectable area (X).

The reflecting unit 400 may be disposed closer to the light emitting unit 600 than the sensor unit 700.

The reflecting unit 400, the sensor unit 700 and the light emitting unit 600 are arranged in the front and rear directions based on the floor, and the reflecting unit 400 is arranged in the width direction based on the floor. It can be.

The plurality of reflection units 400 may be arranged symmetrically to the sensor unit 700.

The plurality of reflection units 400 may be arranged symmetrically with the sensor unit 700 and the light emitting unit 600.

Figure 31 shows the structure of the filter cover of the laundry treatment device of the present invention.

Figure 31(a) shows a lower perspective view of the filter cover 382, and Figure 31(b) shows the lower surface of the filter cover 382 provided with the reflection portion 400.

The filter cover 382 may be provided with a first reflector installation part 3821a that can install the first reflector 410 on the lower surface of the filter cover 382.

The filter cover 382 includes a second reflector installation part 3821b on which the second reflector 420 can be installed on the lower surface of the filter cover 382, and a third reflector on which the third reflector 430 can be installed. It may further include a reflector installation part 3821c. The second reflector installation unit 3821b and the third reflector installation unit 3821c may be provided symmetrically on both sides of the first reflector installation unit 3821a.

The filter cover 382 may be provided with a link installation part 3822 on the lower surface of the filter cover 382, which can install a link 383 that is detachably coupled to the filter fixing part 384.

The filter cover 382 may be provided with a hook 3823 supported on the filter fixing part 384 on the lower surface of the filter cover 382.

The filter cover 382 may be provided with an aroma sheet installation portion 3824 that can install an aroma sheet capable of deodorizing air at the lower part of the filter cover 382.
