Title: WATER DRAINAGE CONTROL MECHANISM FOR AN INNER DRUM, AND WASHING MACHINE
Abstract:
A water drainage control mechanism (400) for an inner drum (100), and a washing machine, the inner drum (100) being provided, at the bottom thereof, with a water drainage port (105), the water drainage control mechanism (400) at least comprising a telescopic valve plug which moves upwards to close the water drainage port (105) and moves downwards to open the water drainage port (105), the water drainage control mechanism (400) further comprising a crank-link structure, the lower end of the valve plug being connected to the link of the crank-link structure, and an idle stroke being provided between the link and the crank and/or between the link and the valve plug. When the valve plug protrudes, but has not yet protruded into the water drainage port (105), the valve plug is pressed against the bottom of the inner drum (100), and a rotary motor (416) drives the crank or the link to move within the idle stroke, when the driving peak of the motor (416) has been exceeded, the motor (416) continues driving the valve plug downwards for resetting and proceeding to the next operation cycle, neither causing any damage to the motor (416) or the inner drum (100), nor requiring manual adjustment or disassembly of the washing machine for maintenance, thereby avoiding malfunction of the washing machine.
