Problems solved by technology

Although the cost of this device is relatively low and the application is relatively mature, it has high requirements on the precision of the mechanical bump switch and is highly dependent on the shaking track of the dehydration bucket. In many cases, when the clothes in the dehydration bucket are unbalanced, due to The uncertainty of the shaking of the dehydration bucket will make it impossible for the outer bucket to hit the mechanical bump switch, resulting in failure of the mechanical bump switch, which will cause the outer bucket to hit the box and abnormal displacement. Or open, can only passively control the dehydration barrel to stop rotating after the barrel collision occurs, and cannot actively adjust the speed according to the eccentricity to avoid the barrel collision, and the user experience is poor

Abstract

The invention discloses a displacement detection device, a washing machine and a control method of the washing machine. The displacement detection device comprises a vibration element and a plurality of displacement detection units; each displacement detection unit comprises a touch part and a measuring part connected with the touch part; the touch parts of the plurality of displacement detection units define an accommodating space; and the vibration element is arranged in the accommodating space; the vibration element can move between the touch parts of the displacement detection units so as to trigger the corresponding measuring parts to generate detection signals. The washing machine comprises the displacement detection device. The control method of the washing machine comprises the step of controlling a dewatering process of the washing machine according to the detection signals of the displacement detection device. According to the displacement detection device, displacement detection in multiple directions can be achieved, the structure is simple, and a detection result is accurate; and in the dewatering operation process of the washing machine, the proper operation speed of the washing machine is adjusted in time through the signals of the displacement detection device, so that the vibration of the washing machine is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a displacement detection device, a washing machine and a control method of the washing machine. Background technique [0002] Clothes processing equipment is a machine capable of washing, drying, dry-cleaning and / or drying clothes. Common clothing processing equipment includes washing machines, shoe washing machines, clothes dryers, dry cleaning machines, and all-in-one washing and drying machines. Take the washing machine as an example. When the washing machine washes the clothes, it will generate a certain vibration. In the case of serious vibration, the washing bucket of the washing machine will be eccentric, and the vibration of the washing machine will generate a lot of noise, which will affect the normal use of the washing machine by the user. , and degrade the user experience. [0003] For example, when the pulsator washing machine is dehydrating, whe...
