Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a dual-axis motor for a drying device and a drying device. Background Art

[0002] A drying device, also known as a dryer, is a cleaning household appliance that evaporates or condenses the moisture in wet clothes and discharges it through mechanical rotation and hot air circulation, and is especially needed in the case of difficult drying of clothes in winter in the north and during the "returning south day" in the south.

[0003] Among them, the wind impeller is one of the key components of the dryer, and its function is to suck hot air into the drum to evaporate the moisture in the clothes. At present, the motors of commercially available dryers only have a set of stator and rotor. One end of the motor shaft is connected to the drum, and the other end is connected to the wind impeller, resulting in the drum and the wind impeller must rotate synchronously at the same speed and in the same direction during use, and the separate control of the drum and the wind impeller cannot be realized. If the drum rotates in one direction all the time, the clothes in the drum will also turn in one direction all the time, which is easy to cause the clothes to tangle and knot with each other, affecting the drying efficiency and resulting in the clothes not being dried or dried unevenly. The prior art discloses a motor, including a split intermediate frame, an outer end cover and a stator assembly. The outer end covers are symmetrically arranged on the left and right sides of the intermediate frame, and the intermediate frame and the outer end cover are separated from each other through the stator assembly. In the actual production process, the prior art requires many assembly parts and a complex assembly process, increasing the production cost. Therefore, in view of the above problems and technical requirements, it is necessary to improve the existing motor for drying devices. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a dual-axis motor for a drying device and a drying device, which can realize the separate drive of the drum and the wind impeller without changing the internal structure of the drying device.
