The condensate unit 500 can store condensate (liquid condensed by heat exchange) generated in the process of dehumidifying indoor air by the heat exchange assembly 200 and automatically discharge the condensed water filled to a certain level to the outside. The condensate unit 500 may include a condensate tank 510, a water pump 520, a discharge pipe 530, a valve 540 and a level switch 550.

The condensate tank 510 may accommodate condensed water generated in the process of dehumidifying indoor air by the heat exchange assembly 200 . The condensate tank 510 may include a part of the lower frame 110, for example, the third chamber 103 of the lower frame 110. In the process of dehumidifying indoor air by the evaporator 210 of the heat exchange assembly 200, condensed water forms on the heat radiation fins and falls downward, and the condensed water is collected in the condensate tank 510. In this embodiment, the condensate tank 510 is configured as a part of the lower frame 110, but the condensate tank 510 may be configured as a separate tank.

The water pump 520 may introduce condensate collected in the condensate tank 510 into the discharge pipe 530. The water pump 520 may be controlled by the controller 600 . The water pump 520 automatically operates when condensate is collected in the condensate tank 510 to discharge the condensed water to the outside through the discharge pipe 530. For example, the water pump 520 may be a motor capable of flowing condensed water.

The discharge pipe 530 may provide a passage through which condensed water is discharged to the outside. The lower end of the discharge pipe 530 may be disposed in the condensate tank 510, and the upper end of the discharge pipe 530 may be disposed to be drawn out of the upper frame 120. A valve 540 capable of controlling the flow of condensed water may be disposed in the discharge pipe 530 .

The valve 540 may be disposed in the discharge pipe 530 to allow or block the flow of condensed water. The valve 540 may include a valve such as a check valve or a solenoid valve. Alternatively, the valve 540 may be a 2-way valve or a 3-way valve capable of allowing or blocking the flow of liquid.

The level switch 550 may measure the level of the condensed water collected in the condensate tank 510 and may adjust the valve 540 so that the discharge pipe 530 is opened. Information on the level of condensed water measured by the level switch 550 may be applied to the controller 600 . When a certain amount of condensate is collected in the condensate tank 510, by the operation of the level switch 550, the valve 540 can open the discharge pipe 530, and the water pump 520 is operated so that the condensate is discharged into the discharge pipe ( 530) may be discharged to the outside.

The controller 600 may control whether the compression/condensation assembly 300, the heat exchange assembly 200, the filter unit 400, and the condensate unit 500 are operated. The controller 600 turns on or off the compression/condensation assembly 300, the heat exchange assembly 200, the filter unit 400, and the condensate unit 500 when an input signal is received from the outside by the user. ) can be controlled.

For example, the controller 600 controls the operation of the water pump 520 so that the water pump 520 is driven for a preset defrosting time when the compressor 310 of the compression/condensation assembly 300 is driven for a preset compression time. You can control it. In particular, when the level switch 550 is operated beyond the preset operating time, the controller 600 determines why the level switch 550 is operated beyond the preset operating time due to an abnormality (operation of the water pump 520). dysfunction). This is because the water level of the condensed water collected in the condensate tank 510 does not decrease and the level switch 550 is continuously operated when the water pump 520 does not operate due to the operation of the water pump 520 or more. In this case, the controller 600 may control the heat exchange assembly 200 and the compression/condensation assembly 300 to stop the operation of the heat exchange assembly 200 and the compression/condensation assembly 300 .

In addition, the controller 600, when the operation of the heat exchange assembly 200 and the compression-condensation assembly 300 is stopped, the discharge fan 220 of the heat exchange assembly 200 and the suction fan 330 of the compression-condensation assembly 300 It can be controlled to be driven during the preset fan driving time. When the discharge fan 220 and the suction fan 330 are operated after the operation of the heat exchange assembly 200 and the compression/condensation assembly 300 is stopped, air flows through the heat exchange assembly 200 and the compression/condensation assembly 300. The heat exchange assembly 200 and the compression/condensation assembly 300 may be dried while doing so. The controller 600 may be implemented by an arithmetic unit including a microprocessor, a memory, or the like, and since the implementation method is obvious to those skilled in the art, a detailed description thereof will be omitted.

The controller 600 may be disposed on the frame 100 adjacent to the condensate tank 510 so that the cold air in the condensate tank 510 is transferred to heat. The controller 600 includes electronic components that generate a lot of heat during the dehumidification operation. As the controller 600 is disposed adjacent to the condensate tank 510, the temperature of the controller 600 is a low heat source of the condensate unit. can be lowered by

The insulation sheet 700 may insulate the condensate unit 500 from the outside. The insulating sheet 700 may be attached to the lower surface of the lower frame 110 in close contact. Since the heat insulation sheet 700 is disposed to entirely cover the lower surface of the lower frame 110 on which the condensate unit 500 is disposed, the low temperature of the condensate unit 500 causes water to form on the lower surface of the lower frame 110. can block it

The insulator 800 may be disposed to cover at least a portion of a side of the base outlet 137b of the base frame 100b to block heat transfer between the base outlet 137b of the base frame 100b and outside air. In other words, the insulator 800 may be disposed on the side of the base outlet 137b of the base frame 100b to block heat transfer with outside air. Alternatively, the insulator 800 may be disposed on the base frame 100b such that a predetermined separation space is formed between the base outlets 137b. For example, the insulator 800 may be positioned in a space between the frame outlet 117b of the lower frame 100 and the base outlet 137b of the base frame 100b, and the insulator 800 may be disposed in the frame outlet 117b. And it may be disposed spaced apart from the base outlet (137b) by a predetermined distance.

The insulator 800 may be a rubber foam insulator (EPDM) having a closed cell structure. Since rubber foam insulation (EPDM) has a closed cell structure in which synthetic rubber is foamed, it has low thermal conductivity and excellent insulation performance, as well as low water absorption and excellent moisture permeability resistance, so that the insulation retention can be maintained for a long time. Even if the rubber foam insulation (EPDM) is configured with a relatively lower thickness than conventional insulation members, it can provide excellent insulation performance.

Hereinafter, the operation and effect of the ceiling air treatment device 1 having the above configuration will be described.

First, the ceiling air treatment device 1 may be disposed on the ceiling surface of a building requiring to provide comfortable indoor air by dehumidifying hot and humid indoor air, such as a dressing room, studio, officetel, and bathroom. Since the ceiling air treatment device 1 itself is disposed on the ceiling surface, there is an effect of increasing the user's space utilization in an indoor space such as a dressing room. In addition, since the heat exchange assembly 200 and the compression/condensation assembly 300 are disposed adjacent to each other with a partition wall interposed in the ceiling air treatment device 1, an external space for disposing a separate outdoor unit may not be required. The efficiency of securing space can be high.

When the ceiling air treatment device 1 is disposed on the ceiling surface of a building, the ceiling air treatment device 1 can sterilize, deodorize, and dehumidify hot and humid indoor air through the heat exchange assembly 200 . For example, the evaporator 210 of the heat exchange assembly 200 may vaporize the low-temperature/low-pressure liquid refrigerant supplied from the condenser 320 of the compression/condensation assembly 300 into a low-temperature/low-pressure gaseous refrigerant. The hot and humid indoor air moving around the evaporator 210 exchanges heat with the evaporator 210 to liquefy or condense the indoor air so that it can be dehumidified.

The refrigerant is compressed by the compressor 310 of the compression condensation assembly 300, and the condenser 320 exchanges heat with the refrigerant using low-temperature flowing air, and the heated and dried flowing air is discharged to the upper space of the ceiling surface again. can The compressor 310 and the condenser 320 of the compression/condensation assembly 300 are disposed in a space above the ceiling surface, and when the condenser 320 condenses the refrigerant, the flowing air in the space above the ceiling surface is utilized as a heat exchange medium. can In addition, since the condenser 320, the suction fan 330, and the compressor 310 of the compression condensation assembly 300 are unidirectionally disposed in all directions from the inlet to the outlet, the flowing air is supplied to the condenser 320 by the suction fan 330. ), and cooling performance by the condenser 320 may be increased. When the cooling performance of the condenser 320 is increased, the dehumidification efficiency of the heat exchange assembly 200 may also be increased.

Meanwhile, the frame 100 may be provided with a plurality of chambers capable of preventing or suppressing the mixing of the moving air and the room air having different properties and flowing together. Since the first chamber 101 through which indoor air flows and the second chamber 102 through which flowing air flow are partitioned from each other, a passage through which flowing air having different properties and indoor air flow independently without mixing can be secured. can In this way, since the heated and dried flowing air is not mixed with the flowing air, the dehumidification efficiency of the heat exchange assembly 200 can be increased.

In addition, indoor air introduced into the ceiling air treatment device 1 may be deodorized and sterilized by the photocatalytic filter 410 of the filter unit 400, and then dehumidified by the evaporator 210 and dried. The indoor air deodorized and sterilized by the photocatalyst filter 410 is dehumidified by the evaporator 210 and discharged to the room, and then the dehumidified indoor air is returned to the base inlet 137a of the ceiling air treatment device 1. The process of inflow through can be repeated. Since indoor air dehumidified by the evaporator 210 passes through the photocatalytic filter 410 during this repeated process, the reactivity of the photocatalytic filter 410 can be increased.

In addition, by the condensate unit 500, condensate generated in the dehumidifying process can be automatically discharged to the outside. Therefore, since there is no need to replace the water container in which the condensed water is separately collected, user convenience can be increased.
