Washing machine and dehydration vibration detecting device and method thereof

Abstract

The invention discloses a washing machine and a dehydration vibration detecting device and method thereof. The dehydration vibration detecting device comprises an accelerated speed detecting module arranged on a motor of the washing machine and used for detecting the dehydration vibration accelerated speed of the washing machine, a speed detecting module used for detecting the rotating speed of a dehydration tub of the washing machine, and a vibration calculating module. The vibration calculating module is connected with the accelerated speed detecting module and the speed detecting module, used for calculating the vibration displacement of the washing machine according to the vibration accelerated speed and the rotating speed so as to obtain the vibration situation of the washing machine. By means of the device, the vibration displacement of the washing machine can be calculated according to the vibration accelerated speed and the rotating speed of the dehydration tub of the washing machine during dehydration, the vibration situation of the washing machine is obtained, the washing machine selects the next dehydration action according to the vibration situation, and therefore the purposes of shortening dehydration time and reducing high-speed vibration are achieved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a dehydration vibration detection device of a washing machine, a washing machine and a dehydration vibration detection method of the washing machine. Background technique [0002] When the drum washing machine dehydrates, when the clothes in the dehydration bucket are not evenly distributed, it will cause the drum washing machine to generate large vibrations, which will not only seriously affect the user experience, but also reduce the service life of the drum washing machine. The motor of the drum washing machine has the function of detecting load imbalance. When the imbalance is detected, the vibration of the drum washing machine during dehydration can be reduced by adjusting the rotation speed of the washing machine dehydration bucket or readjusting the load distribution. [0003] In the related art, the dehydration vibration detection device of the drum washing m...

Problems solved by technology

Although this device does not need other devices, due to the limitation of the motor feedback signal, it requires a long detection time (generally greater than 40S), and cannot detect high-speed vibration and transient vibration in real time, resulting in a long dehydration time of the front-loading washing machine and high-speed The rotational speed cannot be adjusted during dehydration, resulting in high-speed dehydration with large vibration
