Description

Technical Field

[0001] This utility model relates to the field of dehumidifiers, and in particular to a fan for dehumidifiers. Background Technology

[0002] Existing dehumidifiers with compressors typically place the fan between the evaporator and the condenser. The evaporator traps moisture in the air, which is then collected as water droplets and discharged into a water tank. The condenser then condenses the remaining water droplets in the air and releases the dried air back into the atmosphere, thus completing the dehumidification process.

[0003] However, with this design, since the evaporator and condenser are usually positioned opposite each other, the fan can only be a regular fan with relatively low power, which reduces the dehumidification efficiency of the dehumidifier. By placing the fan on one side, a cross-flow fan can be used, which can effectively increase the fan's working efficiency. Furthermore, the cross-flow fan's design of inlet air at both ends and outlet air on the side is very suitable for dehumidifiers, allowing the air outlet of the cross-flow fan to be directly used for top airflow without the need for special air duct design, thereby reducing production costs.

[0004] However, the existing combination of ordinary fans and condensers is not ideal. Therefore, a dehumidifier fan with a connection frame that is compatible with the condenser is needed to better draw air through the condenser and improve dehumidification efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide a dehumidifier fan with a connecting frame that is compatible with the condenser, which can better allow air to enter through the condenser and improve dehumidification efficiency.

[0006] This utility model proposes a fan for a dehumidifier, including a front fan housing, a rear fan housing, an impeller, a motor rotor, and a motor stator;

[0007] The front housing and the rear housing of the fan are fixedly connected. A housing connecting post is provided on the inner side of the rear housing. The impeller is rotatably connected to the housing connecting post and is limited between the front housing and the rear housing.

[0008] The motor stator is fixedly connected to the outside of the housing connecting column, and the motor rotor is fixedly connected to the inner side of the impeller. The motor stator and the motor rotor cooperate to drive the impeller to rotate.

[0009] The front housing of the fan is provided with a connecting frame adapted to the condenser of the compressor. The connecting frame is fixedly connected to the condenser. An air inlet hole is provided on the inner side of the connecting frame. The front housing and the rear housing of the fan are respectively provided with a front housing air outlet slot and a rear housing air outlet slot. The front housing air outlet slot and the rear housing air outlet slot are combined to form a housing air outlet. The air is driven by the impeller to pass through the evaporator and the condenser in sequence to complete the dehumidification process. Then, the air enters from the housing air inlet hole and exits from the housing air outlet hole.

[0010] Preferably, a plurality of connecting buckles are provided on the rear side of the front housing of the fan, and a plurality of connecting blocks are provided on the front side of the rear housing of the fan. The front housing of the fan and the rear housing of the fan are locked together by the cooperation of the connecting buckles and the connecting blocks.

[0011] Preferably, the front housing of the fan is provided with a front housing threaded post, and the rear housing of the fan is provided with a rear housing threaded post. The front housing threaded post and the rear housing threaded post are connected by screws, thereby fixing the front housing of the fan and the rear housing of the fan in place.

[0012] Preferably, an impeller connecting groove is provided on the rear side of the impeller, an impeller rotating column is provided in the middle of the impeller connecting groove, and the motor rotor is fixedly connected to the inner side of the impeller connecting groove.

[0013] Preferably, the housing connecting column has a connecting column rotation hole in the middle, and the impeller rotating column is rotatably connected in the connecting column rotation hole, thereby rotatably connecting the impeller to the housing connecting column.

[0014] Preferably, a housing through hole is provided on the rear side of the fan housing, through which external wiring passes and connects to the motor stator.

[0015] The beneficial effects of the dehumidifier fan of this utility model are as follows:

[0016] 1. By setting a connection frame that is integrally molded with the front housing of the fan, it can be better adapted to the condenser, thereby achieving a better dehumidification effect.

[0017] 2. The front and rear housings of the fan are connected by connecting blocks and clips at multiple points, which improves the overall sealing performance. In addition, the threaded connection ensures the stability of the connection. Attached Figure Description
