Abstract

The invention provides refrigerating equipment which comprises a shell, a compressor, a sound isolating cover and a viscoelastic film layer, wherein an accommodating space is formed in the shell; thecompressor is arranged in the shell; the sound isolating cover at least comprises a sound absorbing layer and micro perforation plates which are successively arranged from outside to inside, the soundabsorbing layer is provided with a plurality of first sound absorbing parts penetrating the sound absorbing layer, and at least one perforation plate is arranged and a plurality of second sound absorbing parts penetrating the micro perforation plate are arranged on the micro perforation plate; when the radiation noise frequency of the compressor reaches a first frequency, the viscoelastic film layer resonates to consume energy and drive air to fluctuate in a reciprocating manner between the first and second sound absorbing parts to rub to consume energy; when the radiation noise frequency ofthe compressor reaches a second frequency, an air column in the second sound absorbing part resonates, rubs with the second sound absorbing part to consume energy, and at least can drive the viscoelastic film layer in the second sound absorbing part to vibrate to consume energy an drive air in the first absorbing part to fluctuate to consume energy. The refrigerating equipment solves the problem that the refrigerating equipment in the prior art is poor in sound isolating effect to the compressor.

Description

technical field [0001] The invention relates to the technical field of household electrical equipment, in particular to an improvement of the structure of a refrigeration equipment. Background technique [0002] Noise pollution from refrigeration equipment has been a pain point for users of air conditioners for a long time. Low-frequency noise has strong penetrability due to its long wavelength and slow attenuation and long-distance transmission. It has become a key technical issue affecting user experience. [0003] The noise sources of refrigeration equipment, refrigerators and other home appliances are mainly compressor noise and fan noise. The existing compressor noise reduction technology is mainly to wrap the compressor sound insulation cover. A sheet metal sound insulation cover is installed around, and the sound absorption effect is poor. Contents of the invention [0004] In order to solve the problem of poor sound insulation effect of the refrigeration equipment...
