Problems solved by technology

Due to the low frequency of 50HZ and 100HZ and strong penetrability, traditional sound-absorbing materials such as sound-absorbing cotton are difficult to work, and the low-frequency hum is dull, which affects the user experience.

Abstract

An embodiment of the present application provides a base device and a clothes processing device. The base device includes a base, a motor body, a shaft sleeve, and a vibration-damping pad; the motor body includes a drive-connected power part and a motor shaft, and the first end of the motor shaft protrudes On the first side of the power part, the power part can rotate relative to the base; the bushing is arranged on the first side of the power part, the first end of the motor shaft is rotatably supported on the bushing, and the bottom end surface of the bushing is spaced from the base ; At least part of the structure of the damping pad is sandwiched between the shaft sleeve and the base. In the base device of the embodiment of the present invention, when the main body of the motor is working, the electromagnetic excitation force is transmitted to the shaft sleeve. Due to the vibration isolation effect of the vibration damping pad, the shaft sleeve will not transmit the electromagnetic excitation force to the base, and the electromagnetic excitation force is very large. Absorbed by the vibration damping pad to a certain extent, the electromagnetic excitation force transmitted to the base is greatly reduced, the forced vibration of the base can be effectively suppressed, and the external radiation noise of the base can be suppressed.

Description

technical field [0001] The invention relates to the technical field of motor vibration reduction, in particular to a base device and clothes processing equipment. Background technique [0002] Taking the clothes dryer as an example, more and more users choose to use the clothes dryer as a drying tool. Compared with the integrated washing and drying machine, the clothes dryer has the advantages of short drying time, high drying efficiency, energy saving and environmental protection. [0003] Noise is an important indicator to measure the performance of the dryer, and users attach great importance to the noise level of the dryer. Part of the noise source of the clothes dryer is the motor noise, and some types of motors will produce friction noise and impact noise when they work. Since the mains power used in our country is 50Hz, the friction noise and impact noise occur at the multiplier of 50Hz and 100Hz. The electromagnetic excitation force of the motor will be transmitted...
