Description

Technical Field

[0001] This invention relates to the field of dryer accessories technology, specifically to a plastic-sealed integrated motor for a heat pump dryer. Background Technology

[0002] A heat pump dryer is a type of dryer that uses heat pump technology. Unlike traditional resistance heating dryers, it uses a compressor and heat exchanger to extract humidity from the air and convert it into heat energy to dry clothes.

[0003] A Chinese patent document with publication number CN213402631U discloses a dryer motor, which is a plastic-encapsulated motor. It includes a shaft, a rotor assembly, a plastic-encapsulated stator, an end cover, and bearings. The plastic-encapsulated stator includes a stator core, end insulation, coil windings, and a plastic-encapsulated outer shell. The plastic-encapsulated outer shell covers the stator core, end insulation, and coil windings. The end cover is mounted on the front end of the plastic-encapsulated outer shell and has a bearing housing. The bearing is mounted in the bearing housing, and the shaft is supported on the bearing. The shaft has a front shaft extension and a rear shaft extension. One end of the front bracket is equipped with... It has a front mounting boss, and the other end is installed on the front end of the plastic-encased housing. The front axle extension of the rotating shaft extends through the front mounting boss. One end of the rear bracket has a rear mounting boss, and the rear axle extension extends through the rear mounting boss. The other end is installed on the rear end of the plastic-encased housing. The edge of the rear bracket is connected to a support arm, and the end of the support arm is connected to a pin. A driven pulley is installed on the pin, and a secondary pulley is installed on the driven pulley. A drive pulley is installed on the end of the rear axle extension. This structure divides the dryer motor into three independent components: the plastic-encased motor, the front bracket, and the rear bracket.

[0004] In existing heat pump dryers, the encapsulated motor has a tail wire connected to its tail end, with a connector plug at the end of the tail wire. Firstly, during operation, the motor connects to the device via the tail wire plug, and since the motor itself is a single unit without any mounting components, it causes inconvenience for installation and subsequent use. Secondly, the vibrations generated during operation not only affect the motor itself but also the connection between the tail wire and the motor, as well as the connection between the tail wire plug and the device's connector, compromising operational stability. Furthermore, the exposed tail wire is easily entangled with cables from other components, creating a messy and unsuitable solution for practical use, necessitating improvement and optimization.

[0005] Therefore, this invention proposes a plastic-sealed integrated motor for heat pump dryers to solve the above problems. Summary of the Invention
