Description

Technical Field

[0001] The invention relates to the technical field of dehumidifiers, and in particular to a dehumidifier fan assembly with variable wind direction. Background Art

[0002] A dehumidifier is composed of a compressor, a heat exchanger, a fan, a water tank, a casing and a controller. Its working principle is: the fan draws humid air into the machine, passes through the heat exchanger, and the moisture in the air condenses into water droplets. The treated dry air is discharged out of the machine. This cycle reduces the indoor humidity.

[0003] In the prior art, a dehumidifier disclosed in Chinese Patent No. CN112303751B includes an evaporator, a first condenser, a heat absorbing part and a heat dissipating part arranged across the evaporator, and an air supply fan for taking air into the interior of a frame. The heat absorbing part and the heat dissipating part are connected by a heat pipe for circulating a heating medium. The heat absorbing part is arranged on the upwind side of the evaporator, and the heat dissipating part is arranged on the downwind side of the evaporator. A mixing space is formed inside the frame between the heat dissipating part and the first condenser. A portion of the air taken in by the air supply fan is transported to the mixing space through the heat absorbing part, the evaporator, and the heat dissipating part in sequence, and the remaining portion of the air taken in by the air supply fan is transported to the mixing space without passing through the heat absorbing part, the evaporator, and the heat dissipating part.

[0004] In the prior art, since the fan of the dehumidifier rotates in one direction, the wind resistance is large when the fan rotates. Therefore, when this type of dehumidifier dissipates heat from the evaporator by suction and heat dissipation, the heat dissipation effect of the evaporator is not ideal. In order to improve the heat dissipation effect of the evaporator, it is necessary to adopt the above-mentioned method to accelerate the heat dissipation by adding an additional heat dissipation part. If the air supply method of the fan can be adjusted to reduce the wind resistance of the fan, so that the fan can both absorb air to dissipate heat from the evaporator and blow air to dissipate heat from the evaporator, it can not only avoid the use of an additional heat dissipation part, but also effectively improve the heat dissipation effect of the evaporator, and the above-mentioned problem can be solved at the lowest cost.
