Below, with reference to accompanying drawing embodiments of the present invention are described.In addition, the present invention is defined in this mode of execution.
(mode of execution 1)
Fig. 1 is that presentation graphs 1 is the top view of the hermetic type compressor of embodiments of the present invention 1, Fig. 2 is the longitudinal section of the hermetic type compressor of embodiments of the present invention 1, Fig. 3 is the stereogram of access of the hermetic type compressor of embodiments of the present invention 1, major component enlarged view when Fig. 4 is inhomogeneous the pressing of hermetic type compressor of embodiments of the present invention 1, Fig. 5 is the main amplification longitudinal section of the hermetic type compressor of embodiments of the present invention 1.
In Fig. 1 to Fig. 5, seal container 101 accumulates oil 102 in the bottom, and takes in the electronic member 105 that comprises stator 103 and rotor 104 and the compression element 106 that is driven by electronic member 105, and has the inside and outside suction pipe 107 that is communicated with seal container 101.
As compression element 106, can use known compressor.At this, for example use the compressor of reciprocating.Compression element 106 comprises: the cylinder block 110 that for example is formed with pressing chamber 109 cylindraceous; The piston 111 that reciprocatingly slides and insert freely in the pressing chamber 109; The absorbing silencer 112 of the silence space (inner space) 120 that is communicated with compressor 109 with formation.
In the present embodiment, access 114 is for example by NBR(Nitrile butadiene rubber: nitrile butadiene rubber) form.One end (cardinal extremity) of access 114 is fixed in absorbing silencer 112, and its other end (front end) is pressed in the position on every side of the opening end of the suction pipe 107 of the inner peripheral surface of seal container 101.
Wherein, the suction port 113 of this access 114 and absorbing silencer 112 also can be fixed by clamp etc.
This access 114 extends from the suction port 113 of absorbing silencer 112, so that refrigeration agent is guided to the suction port 113 of absorbing silencer 112 from suction pipe 107, and in the mode of the opening end that surrounds suction pipe 107, be pressed in the internal face of seal container 101 by Elastic Contact.Access 114 comprises at least one switch-in part 117 in seal container 101 sides.
In the present embodiment, access 114 comprises the switch-in part (section of blocking of wire) 117 that the internal face side end face (ends of suction pipe 107 sides) from seal container 101 extends inward at the axle direction of access 114.
In addition, the front end at switch-in part 117 is formed with circular intercepting section.Thus, can prevent that switch-in part 117 is along with the process of the service time of compressor extends to axial inside.Wherein, the shape of this intercepting section is arbitrarily, also can omit this intercepting section.
The opening portion of switch-in part 117 forms with inferior limit, and forms when non-loaded, and switch-in part 117 is opening not.In addition, the part of switch-in part 117 is configured in the lower end side of access 114, is formed on the lower face side of compressor.
Wherein, in the present embodiment, refrigeration agent uses R600a.Yet, also can use R134a, R410a or other refrigeration agent.
The following describes work, the effect of the compressor that consists of as described above.
When being made electronic member 105 energising by external power supply, rotor 104 rotations, with this, piston 111 is at pressing chamber 109 interior to-and-fro motion, the compressed action that compression element 106 is stipulated.
By the pressure decreased of pressing chamber 109 when the suction stroke, the pressure decreased of access 114, refrigeration agent from external refrigeration system (not shown) by in the suction pipe 107 guiding compressors.
The silence space 120 of refrigeration agent by absorbing silencer 112 that guides in the access 114 by suction pipe 107 is inhaled in the pressing chamber 109.
The to-and-fro motion of the refrigeration agent that guides to pressing chamber 109 by piston 111 pressing chamber 109 interior compressed after, again discharge to cooling system.At this moment, by decay in the silence space 120 of absorbing silencer 112, reduce noise by the pulsation of compressing the refrigeration agent that produces.
In addition because suction port 113 is communicated with by access 114 with suction pipe 107, so refrigeration agent under the lower state of temperature, be sucked in the absorbing silencer 112, and in pressing chamber 109 interior compressions.Consequently, the unit time of refrigeration agent sucks quality (circulating mass of refrigerant) and becomes large, and refrigerating capacity strengthens, so the efficient of compressor is improved.
On the other hand, compression element 106 is by disc spring 108 yielding supports, so sometimes owing to the impact that is subject to rotor 104 makes compression element 106 large displacement occurs when starting.Compressor also pushes back piston 111 by the pressure in the pressing chamber 109 when stopping sometimes, thereby similarly makes compression element 106 that large displacement occurs.Disc spring 108 makes the vibration attenuation of compression element 106, and is passed to seal container 101, and has reduced rigidity for the vibration that reduces compressor, thereby is difficult to prevent the displacement of compression element 106.Therefore, when high with the rigidity of the access 114 installed with the mode of the internal face butt of seal container 101, large displacement occurs in compression element 106 during the starting/stopping of compressor, access 114 collides with seal container 101 thus, and might make 115 breakages of access assembly department owing to its impact.
Yet, owing to being formed with switch-in part 117 at access 114, so even large displacement occurs for compression element 106, also can make by the bending of switch-in part 117 impact-attenuating due to the collision of access 114 and seal container 101, breakage that can the switching power road.
Namely, when carrying, in the situation such as when shutting down, when in seal container during by flexibly mounted compression element turn, even access is pressed on seal container unevenly, also can relax prying force by the section of blocking, the power of preventing is passed to access, thus can prevent the coming off and the breakage of the periphery of access of access due to the prying force, thus can provide reliability high hermetic type compressor.
In addition, further, in the present embodiment, an end of access 114 is fixed in absorbing silencer 112, and the other end of access 114 is pressed in the position on every side of the open end of the suction pipe 107 of the inner peripheral surface that is positioned at seal container 101.Thus, the refrigeration agent that returns from cooling system directly is inhaled into, so the suction quality of the unit time of refrigeration agent increases, the efficient of compressor improves.In addition, be pressed by access 114, it is large that prying force becomes, but relaxed by switch-in part 117, so breakage that can switching power road 114.
In addition, further, in the present embodiment, switch-in part 117 forms from the end of the suction pipe side of access 114 and extends inward.Thus, the end of the suction pipe side of access 114 is truncated, so the rigidity of the end of the suction pipe side of access easily and effectively reduces.
In addition, further, in the present embodiment, switch-in part 117 is wire.Thus, because switch-in part 117 be wire, so be sucked into the amount of the refrigerant gas that warms up of absorbing silencer 112 from the inner space of seal container 101 also harmless less, can suppress the reduction of the efficient of hermetic type compressor.
In addition, further, in the present embodiment, the switch-in part 117 of wire extends at the axle direction of access 114.Thus, when switch-in part 117 when the axle direction of access 114 extends, the axial tensile strength of access 114 reduces, access 114 is easily damaged, but, by this structure, can suppress the reduction of the axial tensile strength of access 114, and the rigidity of end of the suction pipe side of access 114 is descended.
In addition, further, in the present embodiment, the part of switch-in part 117 is disposed at the lower end side of access 114.Be liquid refrigerant or when containing a large amount of oil 102 when guide to refrigeration agent in the access 114 by suction pipe 107, as shown in Figure 5, refrigeration agent or oil 102 are because than great, so a part is accumulated in the lower surface of access 114, but, they are owing to being discharged from from switch-in part 117, thus can prevent from being inhaled into from access liquid refrigerant or oil, thus can prevent the decline of the suction efficiency of refrigeration agent.
Particularly, access and seal container are close to, so heavy liquid refrigerant or oil accumulate in the access bottom, still, discharge from switch-in part, so can provide reliability higher and high efficiency hermetic type compressor at every turn.
Wherein, in the present embodiment, probably be arranged at intervals with three switch-in parts 117 with 120 degree, still, as long as be provided with at least a switch-in part 117.For example, switch-in part also can be two, perhaps more than four.
(variation)
Wherein, in the present embodiment, access 114 comprises the switch-in part 117 that extends inward at the axle direction of access 114 from the internal face side end face of seal container 101, but, so long as the part of switch-in part 117 is configured in the structure of the lower end side of access 114, also can adopt other mode.
