Device and method for detecting vibration noise in dewatering phase of double-roller washing machine

Abstract

The invention relates to a device and method for detecting vibration noise in the dewatering phase of a double-roller washing machine. The device comprises a machine body. A first washing barrel and a second washing barrel are horizontally arranged in the machine body in the vertical direction, fixed to the machine body through a first suspension mechanism and a second suspension mechanism and controlled to rotate by a drive device respectively. At least one three-dimensional non-balanced sensor is arranged in each washing barrel, and the drive device and the three-dimensional non-balanced sensors are connected with a controller respectively. According to the technical scheme, the three-dimensional non-balanced sensors are arranged in the first washing barrel and the second washing barrel respectively, the actual vibration amount of the first washing barrel and the actual vibration amount of the second washing barrel are continuously detected through the three-dimensional non-balanced sensors, and the vibration amount is transmitted to a controller by a signal receiving and transmitting device to be further analyzed and judged. According to the detection device, detection results are accurate, and the problem of inaccuracy brought by traditional indirect measurement can be effectively solved.

Description

technical field [0001] The invention relates to a detection device and a detection method for vibration noise in the dehydration stage of a double-drum washing machine. Background technique [0002] The vibration noise in the dehydration stage has always been the key to the performance improvement of the washing machine. The traditional detection of the vibration of the washing tub is mostly based on the detection of the motor speed to obtain the unbalanced load. This is an indirect measurement method based on the motor speed. The transmission The consistency of the structure and performance parameters of each component of the system will affect the accuracy of the measurement, so it is difficult to obtain a better effect of vibration and noise reduction. However, because the double-drum washing machine is arranged with two washing tubs in the upper and lower directions, there are two washing tubs rotating at high speed at the same time, and the structure of the double-drum ...

[0002] The vibration noise in the dehydration stage has always been the key to the performance improvement of the washing machine. The traditional detection of the vibration of the washing tub is mostly based on the detection of the motor speed to obtain the unbalanced load. This is an indirect measurement method based on the motor speed. The transmission The consistency of the structure and performance parameters of each component of the system will affect the accuracy of the measurement, so it is difficult to obtain a better effect of vibration and noise reduction

However, because the double-drum washing machine is arranged with two washing tubs in the upper and lower directions, there are two washing tubs rotating at high speed at the same time, and the structure of the double-drum washing machine is more complicated, and the consistency of its structure and performance parameters is more difficult to guarantee, so it must be Using a reasonable detection method to control the vibration of the washing bucket can effectively solve the problem of vibration and noise of the whole machine, so as to obtain a better effect of vibration and noise reduction
