Abstract

Provided is a dehumidifier. The dehumidifier includes a compressor which circulates a refrigerant, a condenser which condenses the refrigerant, and an evaporator which faces the condenser. Herein, a tube which is disposed in a plurality of rows with respect to the condenser is coupled to a plurality of fins of which a part or all are separated, and a part of a plurality of rows of tubes is not fixed, and thus an air path is ensured relatively largely, and air can smoothly flow, and condensing performance is enhanced, and a temperature of an end of the condenser can be lowered, and cycle efficiency is enhanced.

First claim

What is claimed is:

1 . A dehumidifier comprising:
a case having an inlet port and a discharge port; a compressor to compress a refrigerant; a condenser to condense the compressed refrigerant; an expander to expand the condensed refrigerant; an evaporator to evaporate the expanded refrigerant; and a fan to provide an airflow from the inlet port to the discharge port, wherein the condenser comprises:
a tube through which the refrigerant flows, the tube formed having a plurality of rows of tubes, and
a fin to exchange heat, the fin being attached to the tube, the fin comprising:
a first row fin attached to a first row of tubes among the plurality of rows of tubes, and
a second row fin attached to a second row of tubes among the plurality of rows of tubes,
whereby at least a portion of the first row fin is separate from the second row fin.

2 . The dehumidifier of claim 1 , further comprising:
a third row fin of which at least a portion of the third row fin is separate from the second row fin; and a third row of tubes at which the third row fin is attached.

3 . The dehumidifier of claim 2 , wherein the condenser comprises a condenser fixing part to support the tube, wherein the condenser fixing part comprises a first fixing part to support a first side of the tube and a second fixing part to support a second side of the tube.

4 . The dehumidifier of claim 3 , wherein the first fixing part supports the first sides of the first, second, and third row tubes, and the second fixing part supports the second side of the first row tubes and is spaced apart from the second and third row tubes.

5 . The dehumidifier of claim 4 , wherein a width of the first fixing part is larger than a width of the second fixing part.

6 . The dehumidifier of claim 4 , wherein, while a first side of the second and third row tubes are supported at the first fixing part, and the other sides of the second and third row tubes are movable with respect to the first fixing part.

7 . The dehumidifier of claim 4 , further comprising:
a blocking wall which is provided at an outer circumferential surface of the fan assembly and blocks the air from flowing to an outside of the fan assembly; and a supporting part to support outside surfaces of the evaporator and the condenser.

8 . The dehumidifier of claim 7 , wherein the evaporator comprises an evaporator fixing part to support a tube of the evaporator, whereby the evaporator fixing part is coupled with the condenser fixing part by a first fastening member and coupled with the supporting part by a second fastening member.

9 . The dehumidifier of claim 4 , wherein the fin further comprises a connection part to couple two adjacent fins, whereby the connection part comprises a first connection part to connect the first row fin with the second row fin, and a second connection part to connect the second row fin with the third row fin.

10 . The dehumidifier of claim 9 , wherein the first connection part and the second connection part are provided parallel to each other.

11 . The dehumidifier of claim 9 , wherein the first connection part and the second connection part are provided at heights corresponding to each other.

12 . The dehumidifier of claim 9 , wherein the first and second connection parts are provided at an extension line which extends forward and backward from one of the second row tubes.

13 . The dehumidifier of claim 9 , wherein the first and second connection parts are provided at different heights from each other.

14 . The dehumidifier of claim 13 , wherein the first connection part is provided at a first extension line which extends backward from one of the first row tubes, and the second connection part is provided at a second extension line which extends backward from one of the second row tubes.

15 . The dehumidifier of claim 13 , wherein the first connection part is provided at a first extension line which extends forward from one of the second row tubes, and the second connection part is provided at a second extension line which extends forward from one of the third row tubes.

16 . A condenser for a dehumidifier comprising:
a tube through which a refrigerant flows, the tube formed having a first, second, and third row of tubes; a fin to exchange heat, the fin being attached to the tube, wherein the fin comprises:
a first row fin attached to the first row of tubes,
a second row fin attached to the second row of tubes, the second row fin being separate from at least a portion of the first row fin,
a third row fin attached to the third row of tubes, the third row fin having at least a portion thereof being separate from the second row fin.

17 . The condenser of claim 16 , further comprising:
a condenser fixing part to support the tube, wherein the condenser fixing part comprises a first fixing part to support a first side of the tube and a second fixing part to support a second side of the tube.

18 . The condenser of claim 17 , wherein the first fixing part supports the first sides of the first, second, and third row tubes, and the second fixing part supports the second side of the first row tubes and is spaced apart from the second and third row tubes.
