The water in the clothes being removed undergoes centrifugal motion under high-speed rotation. The water splashes out of the inner tank through the holes around the inner tank shell, thereby achieving the purpose of dehydration.

The barrel body is fixed on the base, and electrical components are arranged in the base. The cover frame component is fixed to the upper end of the barrel body, and a dehydration timer is arranged on the cover frame component to cooperate with the electrical components. The motor is located in the base, and the rotating cage is located in the barrel body. A connecting shaft sleeve is fixed on the rotating cage bottom plate at the bottom end of the rotating cage, and the motor shaft cooperates with the connecting shaft sleeve to form a linkage structure. The feature of the dehydrator is that a base end plate is arranged at the connection between the base and the barrel body, a motor mounting plate is arranged in the base, and a plurality of flexible connectors are arranged between the base end plate and the motor mounting frame, and each flexible connector is fixedly connected to the base end plate and the motor mounting plate through a fastening element, and the motor is fixed on the motor mounting plate.

[0009] As another solution, in the above-mentioned dehydrator power assembly, the transmission structure includes a driving gear fixed on the motor main shaft, a driven gear is fixedly connected to the lower end of the rotating shaft, and the driving gear and the driven gear are meshed.

The number of through holes and screws is the same and their positions correspond one to one. The screws pass through the corresponding through holes, and each screw is threaded with two nuts. The two nuts on the same screw are respectively pressed tightly on both sides of the mounting plate to facilitate the disassembly and assembly of the motor and subsequent maintenance.

[0013] In the above-mentioned dehydrator power assembly, fan blades are provided above the motor, and the upper end of the motor main shaft extends out of the motor casing and is fixedly connected to the fan blades to accelerate the heat dissipation of the motor and further improve the working stability and life of the dehydrator.

[0014] In the above-mentioned dehydrator power assembly, the type of the elastic shock absorber is a spring shock absorber or a rubber shock absorber.

[0015] Compared with the prior art, this dehydrator power assembly has the following advantages:

[0016] 1. The motor is suspended and fully supported on the positioning frame, and the positioning frame is fully compressed and supported by the elastic shock absorber, so that the elastic shock absorber can play a stronger shock absorbing and buffering role to ensure the stable operation of the dehydrator.
