Abstract

The utility model discloses a noise-reducing device for a compressor, which comprises a sound isolation layer which can make the compressor sealed, a curved metal pipe, and a back flow pipe whose one end is communicated with an evaporator and the other end is connected with the compressor. The curved portion adheres to the surface of the compressor, and the sound isolation layer makes the compressor and the metal pipe which is arranged on the surface of the compressor sealed. Thus, the integration of the compressor is packed and sealed with sound-absorbing materials on the circumference of the compressor to reduce the diffusion of the noise, and simultaneously, in order that the heat quantity generated by the operated compressor can be emitted, refrigerant which is obtained by the back flow of the evaporator is guided to the metal pipe which adheres to the surface of the compressor body. The heat quantity generated by the operated compressor can be absorbed through the refrigerant with low temperature or low voltage in the metal pipe.

Description

The compressor noise-reduction device

The utility model relates to a kind of compressor noise-reduction device of the device that reduces compressor noise, especially household electric appliance.

Need ceaselessly refrigeration agent compression wherein be made it circulation at refrigeration industry with compressor as refrigeration to refrigerator, air conditioner etc., with the purpose that reaches cooling or heat up, and as long as compressor operation work just certainly leads to noise, thereby reduce the emphasis that compressor noise just becomes the sector concern.All be provided with silencer in the general compressor, pass and shed but unavoidably still have the body of noise by compressor.The noise that when compressor operating, produced such as household electric appliance such as air conditioner, refrigerator particularly, because the narrow and small and sealing of family environment, even noise is in 50 decibels, can feel still that indoor interference is too big, and influence family life environment, generally consider the compressor that makes a noise sound insulation housing seal, but must consider the heat dissipation problem of compressor simultaneously.And the volume of household electric appliance has limited the optional equipment of the bigger cooling noise abatement of impossible increase.

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of domestic environment that is particularly suitable for is provided, and further reduces the compressor noise-reduction device of household electric appliance compressor noise.

The utility model purpose is achieved through the following technical solutions:

The utility model compressor noise-reduction device, comprise that one can be with compressor sealing puigging wherein, wherein, one sweeping metal tube, the one end is communicated with vaporizer, the other end is connected in compressor (air inlet) reflow pipe, and curved section attaches and to be arranged at compressor surface, described puigging with compressor together with placing its surperficial metal tube to be sealed in wherein.Described metal tube with copper for well.

This curved shape metal tube can be that helical is around placing the compressor outer surface; Also can be crooked S-shaped, attach and be arranged at compressor surface,

This puigging can be a seal casinghousing; Also can coat its outer forming of sealing by flexible sound absorbing material.

The utility model be around compressor with sound absorbing material the whole environmental sealing of compressor to reduce the diffusion of noise, the heat that is produced when not making compressor operating can't distribute simultaneously, so that influences the proper functioning of compressor.Therefore the refrigeration agent that refluxes from vaporizer is caused the metal tube that is attached at the compressor block surface, the heat that is produced during by the low temperature in the metal tube, low pressure refrigerant absorption compressor operating, and the low-temperature low-pressure refrigerant of backflow is vaporized, make compressor proper functioning under sealed environment.

Below in conjunction with drawings and Examples embodiment of the present utility model is described further:

Fig. 1 is provided with schematic representation for the utility model embodiment 1 inner layer metal pipe;

Fig. 2 is provided with schematic representation for the utility model embodiment 2 inner layer metal pipe;

Fig. 3 is the utility model embodiment 1 cross-sectional view.

As shown in Figure 1, on the compressor body 1 of one refrigerator around copper pipe 2 is set, one port 21 of this copper pipe 2 is connected with the vaporizer (not shown) of a refrigerator, it is reflow pipe 3 from the connecting port around the air inlet mouth of pipe that the compressor attaching places compressor surface, another port to be connected in compressor that copper pipe extends into helical.As shown in Figure 3, compressor together with the copper pipe super glass wool environmental sealing that attaches around the home thereon, is promptly formed the puigging 4 of sound absorbing material formation.Its material also can be sound-absorbing materials such as the fire-retardant acoustic foam of polypropylene-base, polystyrene.The also available soundproof material of sealing means is made full enclosed type sound insulation shell.

Fig. 2 is provided with schematic representation for embodiment 2 inner layer metal pipe, and copper pipe 2 is to attach and place compressor surface with the S shape curved shape that circles round,

The utility model repeatedly can increase cooling surface area with the metal tube bending of circling round.So that the refrigeration agent that vaporizer is refluxed causes the metal tube 2 that is attached at the compressor block surface more, the heat that is produced during by the low temperature in the metal tube, low pressure refrigerant absorption compressor operating, also can further make simultaneously the low-temperature low-pressure refrigerant vaporization of backflow, make compressor proper functioning under sealed environment.

The utility model need not set up optional equipment, and volume increases limited, is particularly useful for the less household electric appliance of volume.
