Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] combine figure 1 , figure 2 and Figure 6 As shown, a drainage traction device for a washing machine includes a traction motor 3 , a casing 1 protecting the traction motor 3 and an end cover 2 , and the traction motor 3 is fixedly installed in a cavity formed by the casing 1 and the end cover 2 . The drainage traction device also includes a cam switch device and an electronic switch 14 for controlling the action of the traction motor 3, wherein the electronic switch 14 is controlled by the program of the washing machine, and controls the traction motor 3 to start at a specific point in time, and the cam switch device is controlled by the traction motor 3. The self-rotation trigger is used to control the traction motor 3 to rotate to a specific position and then stop.

Abstract

The invention relates to a washing-machine water-draining traction device. The washing-machine water-draining traction device comprises a traction motor, a cam switch device and an electronic switch,wherein the cam switch device comprises a cam connected with a rotating shaft of the traction motor and a physical switch which is arranged on one side of the cam and is in contact with the cam, and the physical switch is connected with the electronic switch in series to form a double-control switch to control powering on or powering off of a power source of the traction motor; the electronic switch is controlled and switched by the washing-machine process, and the physical switch is controlled and switched by the rotating position of the cam. The invention also relates to a washing machine provided with the water-draining traction device. According to the washing-machine water-draining traction device and the washing machine, running and stopping of the traction motor are jointly controlled by the physical switch and the electronic switch, the rotating angle of the cam is controlled through the shape and the position of the cam, closed-loop control is formed, and the accuracy and thereliability of controlling are effectively improved.

Description

technical field [0001] The invention relates to laundry equipment, in particular to a washing machine drainage traction device and a washing machine equipped with the drainage traction device. Background technique [0002] At present, the drain valve of the general washing machine all uses two control lines, and the drain valve is driven by the traction motor to work. When in the washing state, the traction motor pull rope is in the initial state. When dehydration starts, the traction motor is energized to drive the reel to rotate, so that the reel winds up the stay cord and tightens it to open the drain valve. After the dehydration is finished, the traction motor is powered off, and the stay rope of the traction motor is quickly reset to the initial state, so that the drain valve is closed. Because the rotation of the traction motor is not controlled after the power is cut off, the traction motor is easy to reset when the power is cut off, and it is difficult to maintain t...
