Embodiment Construction

[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0036] Such as figure 2 As shown, this embodiment provides a preferred washing machine, which includes a cabinet 1, a tub assembly 2, a light emitting element 3, a reflective element 4 and a controller 5, wherein the tub assembly 2 is arranged in the cabinet 1, and the tub assembly 2 It includes an outer tub 21, an inner tub 22 and a drive system 23. One of the light-emitting element 3 and the reflective element 4 is installed at the bottom of the box body 1, and the other is installed at the bottom of the bucket assembly 2. The position of the light-emitting element 3 and the reflective element 4 is opposite up and down. The light-emitting element 3 can be an LED lamp for emitting device. The light at a fixed angle is irradiated on the reflective element 4; the reflective element 4 can be a refle...

Abstract

The invention relates to the technical field of washing machines and discloses a washing machine and a vibration imbalance detecting method thereof. The washing machine comprises a box body and a bucket assembly, wherein a light-emitting element is arranged on one of the bottom of the box body and the bottom of the bucket assembly, a reflection element corresponding to the light-emitting element is arranged on the other of the bottom of the box body and the bottom of the bucket assembly, the light-emitting element is used for emitting light at a set angle, and the reflection element is used for reflecting light back to the light-emitting element. The light-emitting element is also connected with a controller, and the controller is used for judging vibration imbalance of the washing machine and controlling the washing machine to stop operating when the strength of the reflected light received by the light-emitting element exceeds a preset range. The space position change between the light-emitting element and the reflection element can be judged by detecting the intensity of the reflected light received by the light-emitting element, accordingly the vibration imbalance situations of the washing machine in all directions in a three-dimensional space are accurately and flexibly detected, detection blind points are effectively decreased, and the damage caused by range-exceeding vibration to the washing machine is avoided.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine and a vibration imbalance detection method thereof. Background technique [0002] The tub assembly is the core component of the washing machine, and its main function is to mechanically rotate to tumble the items to be washed and the fluid in the washing process contained therein. When the washing machine is working, the barrel assembly is required to run smoothly. If the load distribution in the barrel is extremely uneven, the barrel will produce destructive vibration beyond the range, which will damage the parts of the washing machine and affect the life of the whole machine. The destructive vibration is the vibration imbalance. [0003] Such as figure 1 As shown, in the prior art, the detection method for the vibration imbalance of the washing machine generally adopts the mechanical switch 6'. When the bucket assembly 2' vibrates beyond the range, ...
