Problems solved by technology

Therefore, even if the air flowing into the second passage is cooled by the air flowing into the first passage, the air flowing into the second passage cannot be condensed in some cases.
In this case, the air passing through the second passage is released into the room without being dehumidified, and the dehumidification effect is low.

no. 1 approach

[0027] like figure 1 As shown, the dehumidifier 50 of this embodiment has a box-shaped main body case 1 as an outer shell, and the main body case 1 distinguishes the outside of the main body case 1 from the inside of the main body case 1 . On the rear side of the main body case 1 , an air suction port 2 is arranged at an upper portion, and an air suction port 3 is arranged at a lower portion of the air suction port 2 . An air outlet 4 is arranged on the front side of the main body case 1 opposite to the back side. An operation unit 25 is disposed on the upper portion of the main body case 1 .

[0028] The air suction port 2 and the air suction port 3 are provided in a rectangular plane that sucks in air from a direction perpendicular to the rear surface.

[0029] A louver 31 for changing the direction of the air blown out from the air outlet 4 is provided above the air outlet 4 .

[0030] The operation unit 25 receives an input from the user, for example, and displays infor...

no. 2 approach

[0069] Next, refer to Figure 4 , Figure 5 , Image 6 , Figure 7 The dehumidifier of the second embodiment will be described.

[0070] The dehumidifier 51 of the present embodiment is characterized in that the dehumidifier 50 of the first embodiment is provided with an air flow regulator for increasing or decreasing the amount of air flowing through the second passage of the heat exchanger 11 .

[0071] Specifically, as Figure 4 As shown, the air flow regulating unit is composed of an opening and closing unit 19 that opens and closes the second passage of the heat exchanger 11 , and a drive unit 20 that drives the opening and closing unit 19 .

[0072] The opening / closing portion 19 is a flat plate having an area including the upstream opening 18 a disposed between the air inlet 2 and the upstream opening 18 a of the second passage. The opening / closing part 19 is rotatably supported around the drive part 20 provided in the end side of the upstream side opening part 18a...

no. 3 approach

[0095] Next, refer to Figure 8 A dehumidifier according to a third embodiment will be described.

[0096] The dehumidifier 52 of this embodiment is characterized in that, as Figure 8 As shown, in addition to the first dehumidification path through which air X flows and the second dehumidification path through which air Y flows in the structure shown in the first embodiment, a third dehumidification path through which air Z flows is provided. Wherein, the air Z is another part of the air sucked from the air suction port 2 or 3 . In addition, in this embodiment, the total amount of air sucked into the dehumidifier 52 is obtained by adding three pieces of air, a part of the air, another part of the air, and another part of the air. In other words, the other part of the air can be a part of the total amount of air sucked into the dehumidifier 52 excluding the part of the air and the other part of the air.

[0097] Another part of the air (air Z) sucked in by the fan 6 from th...

Abstract

The dehumidifier includes a first passage and a second passage independent from the first passage, and a heat exchanger (11) that exchanges heat between the air flowing in the first passage and the air flowing in the second passage. The amount of air flowing in the second path of the device (11) is less than the amount of air flowing in the first path. Therefore, even if the temperature of the air flowing in the first passage of the heat exchanger (11) rises, the air flowing in the second passage can be sufficiently condensed. As a result, dew can be condensed also in the heat exchanger (11), and the dehumidification effect can be improved as a whole.

Description

technical field [0001] The present invention relates to a dehumidifier for living spaces and the like. Background technique [0002] Dehumidifiers are put into practical use as devices that reduce humidity in living spaces and increase comfort. [0003] As an example of an existing dehumidification device, it includes: a main body casing; a dehumidification part arranged in the main body casing; a device that makes the air outside the body casing sucked from the air suction port pass through the dehumidification part and blow out from the air outlet to the outside of the main body casing fan. [0004] In addition, the dehumidification unit has a refrigeration cycle in which a compressor, a radiator, an expander, and a heat absorber are sequentially connected in a ring shape. And, a part of the air sucked into the main body case from the air inlet by the fan is blown out of the main body case from the air outlet through the heat absorber, the first passage of the heat excha...
