Abstract

The present invention provides a dehumidifier, including a main body, comprising a dehumidification passage in which indoor air is sucked in and the sucked-in indoor air is dehumidified and a reconditioning passage in which reconditioning air circulates, a dehumidification rotor, comprising a dehumidification portion configured to dehumidify the indoor air and a reconditioning portion reconditioned using the reconditioning air, and a condensing heat exchanger, comprising reconditioning air introduction units into which the reconditioning air is introduced and reconditioning air discharge units from which the reconditioning air is discharged. Each of the reconditioning air introduction units of the condensing heat exchanger has a width which, at a position opposite to the reconditioning portion, increases according to a distance from a center of the condensing heat exchanger corresponding to a center of the dehumidification rotor. The reconditioning air discharge units are formed on one side of a circumferential portion of the condensing heat exchanger. Accordingly, the dehumidification performance of the dehumidifier can be improved and noise caused when the dehumidifier is driven can be reduced.

Description

technical field [0001] The present invention relates to a dehumidifier, and more specifically, to a dehumidifier which improves the heat exchange efficiency by improving the flow path of a condensing heat exchanger for cooling regeneration air, and improves the flow inside the condensing heat exchanger . Background technique [0002] In general, dehumidifiers can be classified into dehumidifiers using a refrigeration cycle and dehumidifiers using a drying wheel, depending on how they operate. [0003] A dehumidifier that uses a refrigeration cycle must have a compressor, and there are problems such as the noise of the compressor and the need to secure a space for installing the compressor. Therefore, dehumidifiers that use drying wheels have been used in many cases recently. [0004] The drying wheel has the characteristic of absorbing moisture in the air, so the indoor air is dehumidified while passing through the drying wheel, and the high-temperature air is used to regen...
