Background
Refrigerator products are essential in the homes of a large number of consumers. As daily household appliances, in addition to basic functions of refrigeration, freezing and preservation, noise generated during operation is receiving more and more attention. In order to facilitate short-distance movement during transportation and installation, rollers are installed at the bottom of the refrigerator; in order to be placed stably at a fixed position, the bottom of the refrigerator can use an adjusting foot, so that the refrigerator is kept horizontal on the one hand, and the refrigerator is prevented from moving on the other hand. At present, the refrigerator products on the market basically adopt a mode of adding an adjusting foot by a roller to solve the two problems, or only use the adjusting foot for reducing the cost.
However, sound is transmitted by vibration, i.e. the compressor and the base generate resonance, and the resonance is transmitted to the box body through the ground, so that non-fixed parts such as drawers and shelves in the box body vibrate. The vibration noise generation and transmission path is as follows: compressor vibration, compressor base, box roller, ground, box adjusting foot, box and non-fixed part in the box. The general adjusting foot can not obstruct or reduce vibration, and transmits the working noise of the refrigerator compressor to the front of the refrigerator, so that the user has bad use experience. For compressing the noise of the compressor, flame-retardant foaming materials, damping rubber and other materials can be placed around the compressor, and sound-absorbing materials can be adhered to a cover plate of the compressor to reduce the transmission of the noise. The resonance sound caused by the contact of the compressor and the return air pipe and the exhaust pipe can be eliminated by bending and shaping the pipeline or installing counterweight rubber on the pipe. The resonance between the compressor and the compressor base is not satisfactory improvement method, and the common method is to improve the rubber ring installed on the compressor, but the effect is not satisfactory.
