Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, especially relates to a washing machine. BACKGROUND

[0002] The washing machine is a kind of daily household appliance, and it liberates people from the labor of washing clothes, so it is liked by the majority of users, and it mainly includes a box body, a barrel body, an inner barrel, a pulsator, a motor and a control panel;The pulsator is located in the inner barrel, and the inner barrel is located in the barrel body, and the barrel body is suspended on the box body by a hanger rod, and the control panel controls the motor to wash and dewater.In the completion of washing, the existing full-automatic pulsator washing machine dewatering mode is that clothes move under the driving of the inner barrel, and the dewatering effect is achieved through centrifugal force, when clothes are unevenly distributed, it is easy to vibrate and collide with the barrel during dewatering, and serious displacement occurs, which affects the running quietness of the washing machine and the service life of the motor and mechanical structure.

[0003] The existing full-automatic washing machine avoids the collision with the barrel by the mode that the stop switch is triggered by impact when dewatering is unbalanced, but this mode has the following shortcomings: first, when the eccentricity is too large, the stop switch will also collide with the barrel due to inertia when being triggered;Second, the anti-collision rod is fixedly installed at a position, which may also cause the phenomenon that the barrel collides but the stop switch is not triggered, resulting in that vibration cannot be detected and avoided;Finally, due to the randomness of such impact, the barrel may be eccentric but not collide with the safety switch, which will produce "misdirection", so that the washing machine continues to dewater and continuously impacts the box body, finally causing the displacement or damage of the washing machine box body, and reducing the service life of the washing machine.

[0004] Some existing washing machines use photoelectric sensors to measure the speed and calculate the acceleration to achieve the purpose of controlling the balance of the machine, but they cannot accurately measure and control, and when some eccentricity occurs, the barrel is easy to collide in the initial dewatering speed stage, and multiple calculations are required to try the appropriate dewatering curve for dewatering.

[0005] Nowadays, washing machine products have many functions, and the space utilization in the washing machine is increasingly high, and it is difficult to install the traditional mechanical detection structure in the washing machine with small available space, so how to design a reliable unbalanced detection mechanism in the washing machine with small space is a problem to be solved by the technical personnel in the field.
