Example Embodiment

[0016] The technical scheme of the present invention is as follows: a washing machine drain valve opening and closing control system, including a washing machine drain valve and an opening and closing control circuit. The washing machine drain valve includes a valve body module, a drive module, a seal compensation module, a valve ball, and a control module; the valve body module includes an upper left valve body, an upper right valve body, a middle valve body, and a lower valve body; the lower valve body is divided into two upper and lower sections , The lower part of the lower valve body is at an angle of 135 degrees with the upper left valve body. The wall of the middle valve body is arc-shaped, and the arc forms a recess. A reserved space is formed between the recess and the valve ball. A support structure 10 is provided on the arc-shaped wall. Symmetrical arrangement; the arc-shaped wall connects the upper right valve body with the upper section of the lower valve body, and ...

Abstract

Provided is a system for controlling the opening and closing of a drain valveof a washing machine. The system includes the drain valve of the washing machine, and an opening-and-closing control circuit; the opening-and-closing control circuit includes a relay K1, a capacitor C1,a controller, a switch K, a relay K2, a resistor R1/R2/R3, a time relay S1/S2, and a driver; two ends of the capacitor C1, two ends of the controller and two ends of the relay K1 are connected with a power supply, a first pin of the controller is connected to coils of the time relay S1, a second pin of the controller is connected to coils of the time relay S2 and connected with the relay K2 at the same time, the time relay S1 and the time relay S2 are connected in parallel, a normally-open pin of the time relay S1 is connected with the resistor R1, a normally-open pin of the time relay S2 is connected with the resistor R2, one end of the driver is connected with the time relay S1/S2, the switch K is connected with the resistor R3, and the other end of the resistor R3 is connected with a normally-open pin of the relay K1.

Description

technical field [0001] The invention belongs to the field of washing machines, in particular to an opening and closing control system for a drain valve of a washing machine. Background technique [0002] Washing machine is a common electrical appliance in the life of residents. In the work of washing machine, there will be a drainage program after the work is completed. In the drainage program, a drain valve is used. The drain valve of the prior art such as CN2890519Y all uses a lifting structure to open and close the valve. Due to the structural limitation of the poppet valve, the protruding valve seat will change the direction of the waterway and cause water hammer. [0003] In the civilian field, there are high requirements for noise and quiet work, and water hammer will bring a certain amount of noise, which will cause discomfort to sensitive people. [0004] When washing the existing washing machines, a considerable part of the washing machines will have multiple drain...
