Embodiment
The present invention will be described in detail to reach embodiment below with reference to accompanying drawings.
As shown in Figure 1, it is by being constituted as the bottom with the reciprocating movement type compressor of absorbing silencer that compressor of the present invention is installed: compressor seal container 1 is arranged on the drive motor 2 of compressor seal container 1 inside, compressor body 3.Said compressor self-body 3 can be compressed refrigerant under the dynamic action of drive motor 2, and, by being constituted: cylinder block 11 as the bottom; Connecting rod 12; Piston 13; Valve assembly body 14; Discharge cap 15; Absorbing silencer 100.
As Fig. 2 and shown in Figure 3, absorbing silencer 100 is by being constituted as the bottom: its inner first shell 110 and second shell 120 that forms silence space V; Be arranged at silence space V, the connection body (not shown) of the inflow entrance 111 of first shell 110 that will illustrate below being used to connect and the outflow opening 121 of second shell 120.
Lower Half one side of first shell 110 is formed with inflow entrance 111, and refrigerant will flow into silence space V by inflow entrance 111.And the entry end of inflow entrance 111 is provided with and sucks leading pipe 130.The suction pipe 4 that is inserted into the inner space of compressor seal container 1 directly links together with sucking leading pipe 130, and perhaps both are close.
Be formed with outflow opening 121 above second shell 120.In order to make the compression volume that is directed to compressor body 3 by the refrigerant that is communicated with body (not shown) inflow, outflow opening 121 is connected in the suction port of compressor body 3.Position, outflow opening 121 intermediate portion is that bending forms, and its lower end forms to silence space V prolongation, and the lower end of its prolongation clings to the upper end that is communicated with body (not shown).
Here, silence space V is divided into a plurality of chambeies.In order to make refrigerant be directed to compressor body 3, be communicated with body (not shown) and be communicated with continuously with a plurality of chambeies by silence space V.
To shown in Figure 4, the bottom surface of first shell 110 is formed with first through hole 112 as Fig. 2.First through hole 112 connects the silence space V of absorbing silencer 100 and the inner space of compressor seal container 1, thereby makes the internal pressure of absorbing silencer 100 and the internal pressure of compressor seal container 1 keep balance.Cancel out each other for the pressure that makes absorbing silencer 100 and compressor seal container 1, first through hole 112 is formed with more than 2.In addition, the foot bottom surface of the absorbing silencer 100 of first through hole, 112 1 sides is formed with second through hole 113.By second through hole 113, the oil that remains in the silence space V of absorbing silencer 100 will be discharged to compressor seal container 1, perhaps make oil flow into the silence space V of absorbing silencer 100.
In addition, the outer side surface of first shell 110 is formed with oily guide hump portion 115.Oil guide hump portion 115 centers on first through hole 112 and second through hole 113, and, be used to prevent flow into first through hole 112 and second through hole 113 along the oil that the outer wall of absorbing silencer flows down.To shown in Figure 4, oily guide hump portion 115 can center on a plurality of through holes 112,113 simultaneously as Fig. 2, and perhaps as shown in Figure 5, each through hole 112,113 outer side surfaces are formed with the oily guide hump portion 116,117 that independently centers on each through hole separately.
Oil guide hump portion 115,116,117 can have nothing in common with each other according to the position to the height of lower end.For example, as Fig. 3 and shown in Figure 4, (pressure: when dotted arrow) flowing into the silence space V of absorbing silencer 100, flow into to first through hole 112 rapidly in order to make refrigerant, the height of oily guide hump portion can be shorter relatively when the refrigerant of compressor seal container.On the contrary, for second through hole 113 that oil can not adverse current be discharged to oil (solid arrow), the height of oily guide hump portion can be higher relatively, and therefore, the bottom surface of oily guide hump portion tilts to form.
As shown in Figure 6, the bottom surface of first shell 110 is formed with oil isolation lug boss 118.The inner side surface of shell is formed with set height and protrudes, and can isolate lug boss around the oil of any one through hole in a plurality of through holes.Promptly to isolate lug boss 118 are the peripheries that protrude first through hole 112 of the refrigerant circulation in a plurality of through holes 112,113 with set height to oil, and the oil that can prevent to remain in the bottom of first shell 110 flow into first through hole 112.
The outer side surface of shell is formed with simultaneously or the independent separately oily guide hump portion 115 around a plurality of through holes 112,113, and being housed in oil, to isolate the oily guide hump portion 115 of through hole one side of lug boss 118 relatively low.
In addition, though not shown, the size of a plurality of through holes can have nothing in common with each other.For example, discharge more rapidly for the oil that makes the bottom that remains in shell, second through hole is bigger than first through hole.And, being difficult for spilling in order to make refrigerant and noise, first through hole is littler than second through hole.
Not specified symbol 5 is discharge tubes in the drawing.
Aforesaid compressor of the present invention has following effect with absorbing silencer.
Promptly be arranged at after compression structure part (not shown) driving of the inside of compressor seal container 1, the refrigerant that constitutes freeze cycle will and suck the silence space V that leading pipe 130 flow into absorbing silencer 100 by suction pipe 4.Refrigerant will flow along being communicated with body, simultaneously, and successively by a plurality of chambeies.Then, be drawn into the compression volume of compressor body 3 by outflow opening 121.
At this moment, suck leading pipe 130 because suction pipe 4 is positioned at the position very near with sucking leading pipe 130 or is directly connected in, therefore, refrigerant will directly be drawn into the silence space V of absorbing silencer 100 enclosure.At this moment, the internal pressure of compressor seal container 1 can be higher than the internal pressure of absorbing silencer 100.Therefore, if when 100 of absorbing silencers form a through hole, by this through hole, the oil of compressor seal container 1 can the excessive inner space that flow into absorbing silencer 100.
But, among the present invention, because the bottom surface of absorbing silencer 100 is formed with a plurality of through holes, promptly, first through hole 112 and second through hole 113, therefore, by first through hole 112, the internal pressure of the internal pressure of compressor seal container 1 and absorbing silencer 100 is exchange mutually, thereby can make the internal pressure of absorbing silencer 100 and the internal pressure formation state of equilibrium roughly of compressor seal container 1, and then can prevent that the oil of compressor seal container 1 from excessively flowing into the silence space V of absorbing silencer 100.Simultaneously, by second through hole 113 of absorbing silencer 100, the oil of appropriate amount flow into silence space V, and supplies to compressor body.Perhaps, remain in the oil of the silence space V of absorbing silencer 100, will be discharged to compressor seal container 1, thereby make the oil of appropriate amount flow into the silence space V of absorbing silencer 100 by second through hole 113.Thereby can keep the amount of the refrigerant of the silence space V that is drawn into absorbing silencer 100, and improve the performance of compressor.
In addition, the fluctuation pressure that produces when compressor body 3 sucks repeatedly and discharges can adverse current arrive absorbing silencer 100, and still, this fluctuation pressure will be subdued, thereby can be reduced noise by in first through hole 112 of absorbing silencer 100.
Therefore, when suction pipe approaches the suction leading pipe of absorbing silencer or is directly connected in the suction leading pipe of absorbing silencer, can keep the pressure balance between the internal pressure of the internal pressure of compressor seal container and absorbing silencer, thereby can make the oil of compressor seal container can excessively not flow into absorbing silencer, and, can guarantee that the oil of appropriate amount is supplied with.
