Embodiment 1

[0035] figure 1 Shown is a schematic diagram of a direct drive motor for a dual-drive washing machine, combined below figure 1 Example 1 will be specifically described.

[0036] This embodiment includes a bracket 19, a stator 13 installed on the bracket 19, an outer rotor 9 installed on the outside of the stator 13, and an inner rotor 1 installed on the inside of the stator 13. When the electromagnetic winding of the stator 13 is energized, it will generate The direction of the magnetic field outside the stator 13 is opposite to the direction of the magnetic field inside the stator 13, resulting in the opposite direction of the electromagnetic force generated outside the stator 13 and inside the stator 13, so that the rotation of the outer rotor 9 and the inner rotor 1 is opposite. That is to say, the present embodiment uses a set of electromagnetic windings and a set of magnetic modulation rings to realize that the two rotors rotate in opposite directions, with little wear, ...

Abstract

The invention discloses a power device of a dual-drive washing machine.The power device comprises a direct drive motor, the direct drive motor comprises a stator, an inner rotor mounted at the inner side of the stator and an outer rotor mounted at the outer side of the stator, the power device of the dual-drive washing machine further comprises a dehydration shaft fixedly connected with the outer rotor, an impeller shaft connected with the inner rotor and a slide block arranged between the impeller shaft and the inner rotor; the power device is characterized in that the impeller shaft is sleeved with the slide block, one or more pairs of key groove structures are arranged between the slide block and the impeller shaft enable the slide block to slide in the axial direction of the impeller shaft and can drive the impeller shaft to rotate along the axis of the impeller shaft, a protruding block is arranged on the slide block, and a groove in occlusion with the protruding block is formed in the inner rotor.The power device is low in noise, low in energy consumption, simple in structure and capable of achieving switching between washing and spinning-drying easily and conveniently, and clothes are protected from drawing in spinning-drying operation.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a power device of a washing machine. Background technique [0002] The washing machine in the prior art washes the clothes by agitating the water flow to generate eddy currents. The washing degree of the clothes is proportional to the speed of the water flow, that is to say, the faster the speed of the water flow, the better the washing effect of the clothes. Therefore, in the traditional In single-power washing machines, the speed of water flow is often increased by increasing the power of the engine. However, due to the limitations of the volume and energy consumption of washing machines, the development of single-power washing machines is limited. Based on this, dual-power washing machines came into being. In order to increase the speed of water flow The purpose is to add a pulsator in the dehydration bucket of the washing machine, and greatly increase the water flow speed through the...
