Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The invention provides a method for detecting unbalanced washing machine, referring to figure 1 , figure 1 It is a schematic flow chart of the first embodiment of the method for detecting the unbalance of the washing machine according to the present invention. In the first embodiment, the method for detecting the unbalance of the washing machine includes the following steps:

[0039] Step S100 , when the washing machine is working, irradiate the incident light at a set angle emitted by the optical element 100 on the inner wall of the washing machine box onto the reflective element 200 at a predetermined position of the outer tub 300 .

[0040] The structure of the pulsator washing machine involved in the embodiment scheme of the present invention is as follows: figure 2 As shown, the pulsator washing machine...

Abstract

The invention discloses a method for detecting the unbalance of a washing machine. The method comprises the steps of when the washing machine works, enabling incident light which is emitted by an optical element arranged on the inner wall of a box body of the washing machine and has a set angle to illuminate a reflection element positioned at the preset position of an outer drum; acquiring the reflected light reflected by the reflection element; converting the optical signal of the reflected light into an electrical signal; judging the balance state of the washing machine according to the electrical signal. The invention further discloses a device for detecting the unbalance of the washing machine. After the method and the device are adopted, the problems that a mechanical safety switch is large in installation space, low in sensitivity and low in reliability can be solved, and the beneficial effects of being convenient to install and high in sensitivity and reliability of the device can be achieved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a method and device for detecting unbalanced washing machines. Background technique [0002] When the washing machine washes items, it is necessary to consider the washing items in the storage bucket and the fluid in the washing process. If the distribution of the washing items in the storage bucket is extremely uneven, then the storage bucket will produce improper vibration beyond the normal range, which may affect the zero of the washing machine. Components are damaged, and this improper vibration is called unbalance, which means loss of balance. In the prior art, a mechanical safety switch is usually used to alarm the imbalance of the washing machine, and the power supply is cut off at the same time by using the contact between the accommodating bucket and the mechanical safety switch, thereby forcing the washing machine to stop working. The disadvantage of this alarm method is...
