Preferred described control panel is arranged on the rear portion of described flap.
Control panel reverse reset structure can adopt: described flap and described control panel are hinged by rotating shaft, between described flap and the described control panel control panel reduction torsion spring are set, and described torsion spring set is contained in the described rotating shaft.
For preventing upwards upset of control panel, the rear portion upside of described flap is provided with the limiting plate that clamps the control panel upper surface.
When control panel is resetted and flap clamp closely, the corresponding described limiting plate of described control panel upper surface is provided with spacing preiection.
Preferred described control panel is horizontally disposed with.
Described control panel is plate.
When torsion spring is arranged between flap and the control panel, because the flap fixed space is big, therefore an end of torsion spring is easy to fix on it very much, and control panel volume, position are limited, end for ease of torsion spring is fixedlyed connected with control panel, one side of described control panel is provided with bossed fixed head, in the described fixed head holddown groove is set, and described torsion spring one end inserts in the described holddown groove.
The safety control that the utility model adopts is simple in structure, can control uncovering power-off and the unbalance outage of tub of washing machine in the washing course of washing machine simultaneously by a switch, washing machine security control safety, and control is sensitive, and cost is low.
