Abstract
The present invention provides a casing structure of a closed compressor. The present invention comprises an electric mechanism and a compressing mechanism which are arranged inside a casing, wherein the compressing mechanism is combined with the electric mechanism and can compress cooling media; the inner wall of the casing of the closed compressor is provided with a plurality of depressed noise reduction grooves. The present invention has the advantages that the depressed noise reduction grooves are formed at the inner wall of the casing, the noise generated at compression apparatuses can be effectively reduced under the condition without increasing the thickness of the casing; the present invention can reduce the compressor weight, carry out heat dissipation well and enhance the compressor efficiency.
Description
Technical field
The present invention is the invention of relevant hermetic motor compressor shell mechanism, particularly can reduce the invention of the relevant hermetic motor compressor shell mechanism of noise effectively.
Background technique
Usually, hermetic motor compressor in the enclosure portion compression instrument portion and electrical equipment portion are housed.The method that the noise that produces about the common handlebar compression mechanical part of method that reduces noise and mechanism portion fundamentally reduces, also the noise that produces of handlebar compression instrument portion and electrical equipment portion is isolated the method that reduces with shell.
As shown in Figure 1, in order to reduce noise, the state of forming the shell 10 of compressor is a sealing state.This shell 10 can have multiple shape, but after normally making upper case 11 and lower case 12 with semi-spherical shape, their combinations is made again.That is, upper case 11 and lower case 12 are to make by punching press with dull and stereotyped calendering steel plate, and shell 10 is that upper case 11 and lower case 12 are welded.
But because the inwall F of above-mentioned shell 10 is smooth spherical, and shell 10 inside possess compression instrument portion and electrical equipment portion, and therefore, as shown in Figure 2, the noise that their produce is reflected by inwall F or sees through shell 10 outwards to be propagated.Thereby, can not reduce the shell 10 inner noises that produce effectively.If when increasing the thickness of shell 10 in order to reduce noise, can cause shell 10 heat conduction efficiency to descend, the heat to inside produces can not dispel the heat well.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of hermetic motor compressor shell mechanism, under the situation that need not increase outer casing thickness, reduce the noise of enclosure generation effectively and outwards propagate.
In order to achieve the above object, technological scheme of the present invention provides a kind of hermetic motor compressor shell mechanism, be included in compressor case inside and be provided with the compression instrument portion of electrical equipment portion and suction that combines with it and compression refrigerant, wherein: the shape that the noise that is provided with a plurality of depressions at the compressor case inwall reduces this slot cross-section of groove is the circular shape of entrance part diameter less than inside diameter.
Effect of the present invention be this compressor case structure in the enclosure the wall noise that forms many depressions reduce groove, under the situation that need not increase outer casing thickness, can effectively reduce the noise that compression instrument portion produces.Use this structure not only can carry out the light of compressor, can also dispel the heat well, improve the efficient of compressor.

Embodiment
Below, reach embodiment in conjunction with the accompanying drawings hermetic motor compressor shell mechanism of the present invention is elaborated.
Fig. 3 is hermetic motor compressor one embodiment's sectional arrangement drawing of the present invention; Fig. 4 is the noise states distribution map of hermetic motor compressor of the present invention; Fig. 5 is the decomposing schematic representation of hermetic motor compressor manufacture process of the present invention.
As shown in the figure, hermetic motor compressor shell 100 provided by the invention after hemisphere upper case 110 and lower case 120 assemblings, becomes sealing state by solder bond.In addition, electrical equipment portion (figure slightly) that produces driving force and the compression instrument portion (figure slightly) that utilizes the powered compressor refrigerant of electrical equipment portion are set in shell 100 inside.The noise that forms many depressions on the whole of shell 100 or part inwall reduces groove 130.This noise reduces groove 130 and has arrived a kind of resonant cavity effect.
As shown in Figure 4, noise reduces groove 130 under side projection, is the big circular arc of the little inside diameter of entrance part diameter.When considering Helmholtz's effect, said structure is more rational shape.But,, can make multiple shapes such as hemisphere or round by making the method that noise reduces groove according to actual conditions.In addition, make inwall, inlet diameter, the degree of depth that above-mentioned noise reduces groove 130 brokenly, can help reducing noise more.
The hermetic motor compressor shell of the invention described above is produced as follows.
When wall forms many noises reduction grooves 130 in the enclosure, use etch or pressing usually.
As shown in Figure 5, the working process of etch is as follows.Has placement template M on the sheet metal P of certain thickness and width.Be formed with many hole h on the template M.Then, the corrosive liquid that a corroding metal plate P is not corroded template M is sprinkling upon on the template M, or allows corrosive liquid flow through from template M.
After this corrosive liquid flow to from the hole h of template M, only corrosion corresponded to the sheet metal M surface of hole h, formed noise with this and reduced groove 130.Afterwards template M is separated from sheet metal P,, process with modes such as punching presses the shape that sheet metal P presses upper case 110 or lower case 120.Make shell 100 with this.
In addition,, that is, when the punch process sheet metal is made upper case or lower case, the surface of drift is formed many protrusion members, make it when punching press, be pressed into metal sheet surface though accompanying drawing of no use represents that noise reduces the also available following making method of groove 130.With this, the noise that forms depression reduces groove 130.
After this compressor is switched on power supply, start electrical equipment portion, compression instrument portion utilizes driving force that refrigerant is sucked, compresses the back and exports with high-temperature high-pressure state.In this course, compression instrument portion can produce pulsed pressure wave, and this pressure wave can be propagated along the inwall of shell 100.After propagating into the pulsed pressure wave process noise reduction groove 130 of inwall, can weaken gradually.Thereby, can reduce to greatest extent by shell 100 outside borne noise.
Therefore, under the situation that need not increase outer casing thickness, can reduce the pulsed pressure wave that compression instrument portion produces effectively.Not only can carry out the light of compressor by it, can also dispel the heat well, improve the efficient of compressor.
