Reaching embodiment below with reference to accompanying drawings is described in detail with absorbing silencer compressor of the present invention.
As shown in Figures 1 and 2, compressor absorbing silencer of the present invention is to be made of shell 100 and connecting pipeline 200.Shell 100 is arranged on the inner space of compressor closed casing, and will be directed to compressor body from the refrigerant that freeze cycle is delivered to.Connecting pipeline 200 movably is arranged on the inner space of shell 100, and is used to be communicated with the inflow entrance 102 and the outflow opening 103 of shell 100.
For the noise space 101 that makes shell 100 inside be divided into along the flow direction of refrigerant before and after both sides, shell 100 is made of first shell 110 and second shell 120.Lower Half one side of first shell 110 and second shell 120 is formed with the inflow entrance 102 that the refrigerant that is used to make the compressor closed casing flows into respectively.And inflow entrance 102 is semi-circular shapes.In addition, second shell 120 above be formed with outflow opening 103.Under the effect of outflow opening 103, can make shell 100 be connected to the suction port (not shown) of compressor body.Outflow opening 103 is shapes of position, intermediate portion bending, and its lower end forms to noise space 101 prolongations, and the lower end of its prolongation clings to the upper end of connecting pipeline 200.
The centre of the internal face of first shell 110 and second shell 120 is provided with the expansion face 104 of the noise space 101 that can enlarge shell 100.Expansion facial 104 is separately positioned on first shell 110 and second shell 120, and is cross setting.Expansion facial 104 can be horizontal smooth shape, still, for the fixed lobe 201 that makes connecting pipeline 200 inserts easily, as shown in Figure 2, also can be bent downwardly formation.
Between shell and connecting pipeline, be provided with a plurality of pipeline assembly part, thereby can change the assembling position of connecting pipeline.
The pipeline assembly part is on the outer circumferential face by internal face that is separately positioned on shell and connecting pipeline, and the fixed lobe that can mutually combine and fixed groove constitute.
Be formed with fixed groove 105,106 above the expansion facial 104, the fixed lobe 201 of the connecting pipeline 200 that will illustrate below is inserted in the fixed groove 105,106, and combines with it.As shown in Figures 2 and 3, fixed groove the 105, the 106th prolongs up and down along the length direction of connecting pipeline 200 and to form.At this moment, the lower end surface of fixed groove 105,106 can become the lower face of expansion facial 104, and the upper-end surface of fixed groove 105,106 is structures of sealing, thereby can prevent that fixed lobe 201 from coming off.
Fixed lobe and fixed groove have major axis and minor axis.The long axis direction of fixed lobe and fixed groove is identical with the length direction of connecting pipeline.The short-axis direction of fixed lobe and fixed groove is radially identical with connecting pipeline.
In addition, as shown in Figure 3, in order to change the assembling position of connecting pipeline 200, fixed groove the 105, the 106th is formed so that set interval is transversely arranged by the fixed groove more than 2 or 2.At this moment, in a plurality of fixed grooves 105,106, first fixed groove 105 be the center of its length direction and outflow opening 103 axis roughly point-blank, and the center of the length direction of second fixed groove 106 can with the axis of outflow opening 103 not point-blank.
Connecting pipeline 200 is to be assembled into shell 100 after separately making.As Fig. 2 and shown in Figure 4, the outer circumferential face both sides of the outlet side end of connecting pipeline 200 are formed with a plurality of fixed lobes 201.Under the effect of a plurality of fixed lobes 201, connecting pipeline 200 can optionally be inserted into first fixed groove 105 or second fixed groove 106 of shell 100.As Fig. 4 and shown in Figure 5, the lower end of fixed lobe 201 is formed with chamfered part, thereby can be placed on the expansion face 104 of shell 100.
The external diameter position of connecting pipeline 200 preferably with the inwall of the shell 100 set distance of being separated by, like this, can prevent hot transport phenomenon by shell 100.In addition, in order to reduce the flow resistance of refrigerant, the internal diameter of the connecting pipeline 200 preferably internal diameter with inflow entrance 102 or outflow opening 103 is identical.As shown in Figure 3, the centre of connecting pipeline 200 is formed with the trickle through hole 202 of the internal communication of the noise space 101 that makes shell 100 and connecting pipeline 200.The effect of trickle through hole 202 is to reduce the noise or the pressure pulsation that cause by connecting pipeline 200 adverse current phenomenons.
In aforesaid embodiments of the invention, fixed groove 105,106 is formed on the internal face of shell 100, and fixed lobe 201 is formed on connecting pipeline 200.But in contrast, fixed lobe (not shown) is formed on shell 100, and fixed groove (not shown) is formed on connecting pipeline 200 and also is fine.At this moment, the fixed lobe of shell 100 is the both sides that laterally are formed on shell 100.
Below, will describe the compressor of the invention process that constitutes as mentioned above effect with absorbing silencer.
After the compression structure part (not shown) that is arranged on compressor closed casing inside drove, the inflow entrance 102 of refrigerant by absorbing silencer that is drawn into the inner space of compressor closed casing flow into connecting pipeline 200.Refrigerant flows along connecting pipeline 200, then, behind outflow opening 103, open the suction valve (not shown) of compressor after, be drawn into the compression volume of compression structure part.
At this moment, can regulate the assembling position of absorbing silencer as required.Such as, as shown in Figure 3, the center of the center of connecting pipeline 200 and outflow opening 103 on a line in, refrigerant in the inner space of compressor closed casing is by connecting pipeline 200, directly flow to the outflow opening 103 of shell 100, thereby can make refrigerant be drawn into the compression volume of compression structure part rapidly.Therefore, refrigerant with heat that can not hyperabsorption, but directly is drawn into the compression volume of compression structure part, thereby can improves the performance of compressor in by absorbing silencer.
On the contrary, as shown in Figure 6, the center of the center of connecting pipeline 200 and outflow opening 103 not on a line in, to flow into the noise space 101 of shell 100 to outflow opening 103 mobile refrigerants by connecting pipeline 200, after entering the noise space 101 of shell 100, be drawn into the compression volume of compression structure part by outflow opening 103.In addition, suck the various noises and the vibration that produce in the middle of the process of refrigerant, as, the pressure pulsation that produces in the middle of the process that the suction stroke of the valve noise that produces when suction valve opens and closes, the mobile noise that produces when sucking refrigerant, compressor carries out repeatedly etc. will produce adverse current along the outflow opening 103 of absorbing silencer.But, because connecting pipeline 200 and outflow opening 103 directly do not link together, therefore, valve noise or pressure pulsation are delivered to the noise space 101 that connecting pipeline 200 flow into shell 100 before earlier, and in noise space 101, be cancelled, thereby can reduce the noise of compressor significantly.
In addition,, as follows at compressor of the present invention about another embodiment of the package assembly of connecting pipeline with in the absorbing silencer.That is, in aforesaid embodiment, fixed groove 105,106 and fixed lobe 201 are to prolong along the length direction of connecting pipeline 200 to form.But in the present embodiment, fixed groove and fixed lobe are that the extend radially along connecting pipeline forms.
Such as, as shown in Figures 7 and 8, the left and right sides of the inner side surface of both sides shell 110,120 is formed with first fixed groove 105 and second fixed groove 106 at the set interval that is separated by.In the length direction that is centered close to outflow opening 103 of first fixed groove 105 in the heart, and the center of second fixed groove 106 not in the length direction of outflow opening 103 in the heart.That is, first fixed groove 105 is formed in and can makes on connecting pipeline 200 and the outflow opening 103 assembling positions point-blank.On the contrary, be formed in can not be so that on connecting pipeline 200 and the outflow opening 103 assembling positions point-blank for second fixed groove 106.In this case, also can change the position of connecting pipeline 200 according to the needs of compressor.Because its principle and the aforesaid embodiment of the invention are similar, therefore omit detailed description thereof.
In addition, though not shown, first fixed groove and second fixed groove can be on same height.That is, when first fixed groove and second fixed groove both transversely are separated by set a distance, be different from Fig. 7 and Fig. 8, in the above-below direction set distance of also being separated by.Because its structure and the aforesaid embodiment of the invention are similar, therefore omit detailed description thereof.
