Description

Technical Field

[0001] The invention relates to the technical field of water-saving washing machines, and in particular to a clutch device of a water-saving washing machine. Background Art

[0002] The existing water-saving washing machine needs to discharge the sewage in the washing tub after washing. However, after washing, the clothes will entangle the impeller and the washing tub together. When draining, it is necessary to open the drain pan on the bottom of the washing tub. The drain pan is controlled to open by the drain shaft connected to it. Since the input part needs to control the rotation of the impeller shaft connected to the impeller when controlling the drain shaft, the required torque is large, and the impeller shaft is subject to great resistance from the impeller. In addition, the power controlling the drain shaft and the impeller shaft is directly transmitted by the input end, and the power cannot be amplified by the reduction gear train, resulting in the inability to drain. It is necessary to take out the clothes first, which is not only troublesome, laborious, but also cannot realize automatic control. This is a technical problem that we urgently need to solve.
