Drain valve for wave wheel single tub washing machine

Abstract

The present invention discloses a drain valve of an impeller type single-container washing machine. The drain valve comprises a motor assembly and a drainage assembly, the motor assembly comprises a drive motor and a connecting base, an eccentric wheel is disposed on an output shaft of the drive motor, an eccentric shaft is disposed on the eccentric wheel, the drainage assembly comprises a valve rod, a valve core, a valve plug clamped outside the valve core and a valve body disposed outside the valve plug, a sliding block is disposed in a sliding manner on an upper end of the valve rod and is arranged in a rotating manner on the eccentric shaft, a bottom end of the sliding block is connected with the valve rod through a spring, a lower end of the valve rod is clamped and fixed with the valve core, the valve core penetrates through the connecting base, and the valve body is fixed on a bottom face of the connecting base. according to the drain valve provided by the present invention, the motor rotates to drive the valve rod and thus to enable the valve core to slide up and down; through a combined structural design of the sliding block, a rectangular frame and the spring, the motor and the valve core can be connected in a movable manner, thereby increasing flexibility of the structure; and position dead corners exist, the jammed phenomenon does not occur, and the drain valve is simple in structure and convenient to install.

Description

technical field [0001] The invention relates to a washing machine drain valve, in particular to a pulsator single-tub washing machine drain valve. Background technique [0002] Washing machine is a must-have household electrical appliance. It has various types and different functions. Among them, the single-tub pulsator washing machine has good washing effect, short washing time and low power consumption. The drain valve of a single-tub washing machine is an important component to control whether the internal water flows out. On the current washing machine, the water inlet, drain port and valve plug form an integrated drainage module, while the washing machine only has a drain port on the outer tub, so the integrated The drainage module can only be connected with the drain port on the outer barrel of the washing machine, so that when the washing machine is in use, the inner and outer barrels will store water simultaneously, resulting in waste of water.
