Abstract
This invention discloses a foot structure of a rotary compressor including feet anda compressor chassis, among which, the fet are interleaved uniformly, the internal end of each foot is welded at the bottom of the bottom cover. The advantage is in simple structure, good vibration reduction and noise reduction.
Description
Technical field
The present invention relates to a kind of rotary compressor, particularly relate to a kind of footing mounting structure of rotary compressor.
Background technique
As everyone knows, compressor is the important component part of refrigerator and air conditioner, its effect is that the high-temperature low-pressure gaseous coolant that heat exchanging process forms is compressed into the High Temperature High Pressure gaseous coolant, and the High Temperature High Pressure gaseous coolant is entered coolant circulating system, carries out the next round heat exchange.Compressor can be divided into polytypes such as reciprocal compressor and rotary compressor, and wherein rotary compressor is a kind of compressor that can suck, compress and discharge refrigerant continuously.
As shown in Figure 1, the main working parts of existing rotary compressor is closed in the housing, and footing 01 links together by the mode and the compressor bottom cap 02 of welding, mainly plays a supportive role.During compressor operating, vibration that the enclosure interior workpiece of sealing produces and noise can transmit or radiation to the outside by connected element.Because compressor footing 01 and bottom 02 be for being rigidly connected, so inner vibration is easy to be delivered to footing by bottom 02, and excitation footing 01 produces and vibrates, and then the generation noise.Because the thickness of the footing mounting structure 01 of existing rotary compressor is relatively thin and area is bigger, so modal density big (annotating: modal density Modal density, the mean number of the resonant frequency of unit bandwidth).Because of the vibration of compressor internal work parts generation and the frequency band broad of noise, accordingly to the also relative broad of the excited frequency of footing 01, thereby footing 01 is easy to take place resonance phenomenon, produces very big vibrating noise again.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above-mentioned shortcoming of the footing mounting structure of existing rotary compressor, and a kind of footing mounting structure of simple in structure, rotary compressor that modal density is low is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the footing mounting structure of rotary compressor of the present invention comprises: footing and compressor bottom cap; Described footing is several at interval uniform separated type footing, and the inner of each footing is welded on the bottom of compressor bottom cap respectively.
Described footing can be three uniform separated type footing in interval, and the inner of each footing is welded on the bottom of compressor bottom cap respectively.
Vibration and noise reducing principle to the footing mounting structure of present embodiment rotary compressor is illustrated below:
During compressor operating, vibration that the enclosure interior workpiece of sealing produces and noise can transmit or radiation to the outside by connected element, though inner vibration can be delivered on the footing by bottom, and the excitation footing produces vibration, and then produces noise.But adopt at interval uniform several separated type footing in the present embodiment, the area of each footing is less, thereby modal density is less, make the natural frequency of footing avoid the excited vibration frequency range, thereby avoided footing to produce the phenomenon of resonance under the effect of excited vibration, effect of vibration and noise reduction is very obvious.
The invention has the beneficial effects as follows: simple in structure, effect of vibration and noise reduction good.Because the area of each footing is less, thereby modal density is less, make the natural frequency of footing avoid the excited vibration frequency range, thereby avoided footing under the effect of excited vibration, to produce the phenomenon of resonance, the area of very obvious each footing of effect of vibration and noise reduction is less, thereby modal density is less, makes the natural frequency of footing avoid the excited vibration frequency range, thereby avoided footing to produce the phenomenon of resonance under the effect of excited vibration, effect of vibration and noise reduction is very obvious.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: the footing mounting structure of present embodiment rotary compressor comprises: footing and compressor bottom cap; Described footing is the bottom that the inner of 03, three footing 03 of three uniform separated type footing in interval is welded on compressor bottom cap 02 respectively.
Vibration and noise reducing principle to the footing mounting structure of present embodiment rotary compressor is illustrated below:
During compressor operating, vibration that the enclosure interior workpiece of sealing produces and noise can transmit or radiation to the outside by connected element, though inner vibration can be delivered on the footing 03 by bottom 02, and excitation footing 03 produces vibration, and then produces noise.But adopt three uniform separated type footing 03 in interval in the present embodiment, the area of each footing 03 is less, thereby modal density is less, make the natural frequency of footing 03 avoid the excited vibration frequency range, thereby avoided footing 03 to produce the phenomenon of resonance under the effect of excited vibration, effect of vibration and noise reduction is very obvious.
