Abstract

The invention provides a washing machine and a control method thereof, which relate to the technical field of washing machines and are used to solve the problem that the drainage pump of the washing machine in the related art is prone to failure. The washing machine includes: a box body; a washing tub with a drain opening at the bottom of the washing tub; a drain pump; a first drain pipe, the first drain pipe extends vertically, and the upper end communicates with the drain port, and the lower end connects with the drain pump. The water inlet is connected; the side wall of the first drainage pipe is provided with a connection port; the second drainage pipe is connected with the connection port at one end and the water inlet of the drainage pump at the other end; the filter, The filter is arranged in the first drainage pipe and is located below the connection port; the valve is arranged between the filter and the connection port; the controller is used to detect the first drainage above the connection port when the metal detector detects When there is metal foreign matter in the pipe, the control valve opens the first drain pipe. The invention can be used for washing clothes.

Description

technical field [0001] The present invention relates to the technical field of washing machines, in particular to a washing machine and a control method thereof. Background technique [0002] Washing machines are cleaning appliances that use electrical energy to produce mechanical action to wash clothes. More and more people use washing machines to wash clothes, bedding and other large items, saving time and effort. Washing machines are becoming an indispensable household appliance in people's lives. [0003] A washing machine in the related art uses a drain pump to drain water, but when the washing machine is draining, metal foreign objects in the washing tub, such as zippers, coins, etc., are easy to enter the impeller cavity of the drain pump with the water flow, and it takes a long time. , the accumulated metal foreign matter is easy to damage the impeller, thus causing the drainage failure of the washing machine. SUMMARY OF THE INVENTION [0004] Embodiments of the p...
