Abstract
The utility model discloses a noise reducing structure of an outdoor machine of an air conditioner, which is composed of the outdoor machine of the air conditioner, and sound absorption blocks, wherein the sound absorption blocks are arranged at the inner side of the outdoor machine and each sound absorption block comprises a sound absorption layer and a support leg; each supporting leg is arranged at the bottom part of each sound absorption layer to separate the sound absorption layer from the adsorbed surface for a certain distance; and the sound absorption layer is made of a porous material. According to the noise reducing structure disclosed by the utility model, a sound elimination block is arranged in a shell of the outdoor machine so that sound waves with all frequency ranges of a compressor of the outdoor machine are prevented from passing through an external machine sheet metal part and the sound waves passing through the sheet metal part are greatly weakened; and therefore, the noise reducing level of the outdoor machine of the air conditioner is improved, harmful noises are eliminated, the sound quality is improved, and the high requirement on the quality of the noises of a customer is met.
Description
Technical field
The utility model relates to refrigeration technology field, more particularly, relates to a kind of air-conditioner outdoor unit denoising structure.
Background technology
Along with people's improves constantly the requirement of quality of the life, and the noise of air-conditioning more and more receives consumer's attention, becomes a big Consideration of choosing air-conditioning.
The noise of air-conditioner outdoor unit mainly comes from blower fan, compressor and the piping system thereof of off-premises station.The mechanical medium and low frequency mechanical noise of medium-high frequency electromagnetic noise that the motor of press body spreads out of and rotor rotation, mutual superposition is to external radiation.In addition, the impact of flowing pipeline being carried out of refrigerant causes the vibration of pipeline, and the secondary through pipeline passes to other parts again, and the narrow-band noise and the stream that can cause medium and low frequency cause noise.The vibration of compressor that refrigerant and compressor drum rotation inertia force cause passes on the casing through foundation bolt and pipe arrangement, causes the vibration of body structure, and further forms high-frequency noises to external radiation.After the off-premises station blower fan rotated, ambient air quickened to flow, and produces rotational noise and turbulence noise, influences each other, to external radiation.The air turbulence that the blower fan system operation time brings causes dither to work as dynamic excitation when consistent with the casing intrinsic frequency to the excitation of casing, resonates, and also can make the noise amplification.The noise of air-conditioner not only causes the pollution of surrounding environment, and influences people's live and work.How to weaken the sound wave of multiband, improve tonequality and become one of center of gravity of air-conditioning scientific research personnel work.Present air-conditioner outdoor unit noise elimination technique mainly is:
1. on the press cylinder body, wrap up Sound-proof material;
2. on the press piping system, increase muffler;
3. through changing its intrinsic frequency for press piping system counterweight (adding balancing weight, anti-vibration rubber etc.), prevent resonance, thus noise reduction;
4. increase median septum;
5. on capillary, wrap up anti-vibration rubber to eliminate fluorine stream sound etc.
Though the noise abatement of these several kinds of common scheme is had nothing in common with each other, the noise of air-conditioning is descended to some extent, still, when the client has higher requirements to the noise quality, more than traditional noise reduction technology then be difficult to satisfy.
The utility model content
The utility model purpose provides a kind of soundproof effect good air-conditioner outdoor unit denoising structure in order to overcome the deficiency that above-mentioned prior art exists.
The technical scheme that the utility model adopts is: a kind of air-conditioner outdoor unit denoising structure; Constitute by air-conditioner outdoor unit and sound-absorbing piece; Said sound-absorbing piece is arranged on the inboard of off-premises station; Said sound-absorbing piece comprises sound absorbing layer and feet, said feet be arranged on sound absorbing layer the bottom, make sound absorbing layer and the appended surface segment distance of being separated by, said sound absorbing layer is made by porous material.
Said sound-absorbing piece is arranged on the shell inboard of air-conditioner outdoor unit.
Said feet is along the outer rim setting of sound absorbing layer.
Be provided with polylith sound-absorbing piece in the shell inboard of air-conditioner outdoor unit, the feet height of two adjacent sound-absorbing pieces is different, makes adjacent sound absorbing layer not at grade.
Said sound absorbing layer is made by sponge.
It is inboard that said sound-absorbing piece sticks on the air-conditioner outdoor unit shell.
Said sound-absorbing piece sticks on the top cover or front panel or median septum or right plate of air-conditioner outdoor unit.
Compared with prior art, the utlity model has following advantage:
The utility model is through being provided with the noise elimination piece in casing of outdoor; Can effectively stop each frequency range sound wave of compressor of outdoor unit to pass outer machine sheet metal component; Sound wave through sheet metal component is weakened significantly, thereby improve the air-conditioner outdoor unit noise abatement, eliminate bad noise; Improve tonequality, satisfy the high request of client the noise quality.

The specific embodiment
Referring to Fig. 1-4, the air-conditioner outdoor unit denoising structure of the utility model is by air-conditioner outdoor unit and stick to the inboard sound-absorbing piece of casing of outdoor and form.Below, be example with the head components of air-conditioner outdoor unit shell, explain as follows:
Referring to Fig. 3,4; The inboard of top cover 3 is pasted with polylith sound-absorbing piece 1 and sound-absorbing piece 2; The feet height of sound-absorbing piece 1 and sound-absorbing piece 2 is different, and both are distributed in the bottom surface of top cover with the mode of bamboo between plum blossom, because the height of feet height is different; Make adjacent sound absorbing layer not at grade, form a structure that rises and falls in order.
Referring to Fig. 1,2; The sound-absorbing piece comprises sound absorbing layer 11 and feet 12; Feet 12 be arranged on sound absorbing layer 11 the bottom, make the bottom surface of sound absorbing layer and the top cover segment distance of being separated by; Make each the frequency range sound wave constantly reflection back and forth between sound absorbing layer and top cover bottom surface that is weakened by sound absorbing layer, be gradually transformed into thermal dissipation and fall.Six feets 12 are symmetrical set along the outer rim of sound absorbing layer 11, form the passage of air-flow between the adjacent supports pin, are beneficial to the propagation and the absorption of sound wave.
Feet can be set to four or eight etc. according to the size of sound-absorbing piece respectively.
The sound-absorbing piece can also stick on the sheet metal components such as the front panel, median septum, right plate of air-conditioner outdoor unit.Stick on the sheet metal component inboard to the sound-absorbing block gap that the feet height is different; The sound-absorbing piece collocation of differing heights is used; Can increase the reflecting surface of sound wave; Increase considerably the order of reflection of sound wave, each frequency range sound wave is weakened before penetrating sheet metal component to greatest extent, thereby reach effects such as noise reduction, the different sound of elimination.
