Embodiment
Further illustrate the technical solution of the utility model below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 2, the first embodiment of a kind of rotary compressor of the utility model is proposed.This embodiment's rotary compressor comprises housing 1 and is arranged on compressing mechanism 2 and the motor 3 in described housing 1, and described motor 3 comprises the stator 31 be fixed on described housing 1 and the rotor 32 of being located at described stator 31 centers.Stator 31 is comprised of stator iron core 311, coiling and insulating element (not shown), and the outer wall of stator 31 is provided with and forms the ventilation breach 312 that upper and lower end face is communicated with, and also be provided with in stator 31 iron cores 311 and form the vent 313 that the stator upper and lower end face is communicated with.Described rotary compressor also comprises and is arranged on the flow apron 4 of described motor 3 away from a side of described compressing mechanism 2, and described flow apron 4 comprises outer side connecting plate 41 and inboard warped boar 42.Described outer side connecting plate 41 is fixedly connected with housing 1, and this flow apron 4 just be positioned at ventilation breach 312 and vent 313 directly over.
Above-mentioned rotary compressor is in when work, and compressing mechanism 2, under the drive of rotor 32, carries out air-breathing, compression, exhaust etc. to refrigerant.Be stored in the lubricant oil of housing 1 bottom owing to directly contacting with compressing mechanism 2.Therefore when pressurized gas during from compressing mechanism 2 discharge, will carry the parts of lubricating oil particle and form gas mixture.When this gas mixture moves to outlet pipe 6 through ventilating breach 312 and vent 313, will be subject to stopping of flow apron 4, turn back thereby occur to flow to.And, because the inertia of oil particles is greater than cold media air, therefore will have more particles hit and be adsorbed on flow apron 4, thereby making lubricant oil separate from gas mixture, effectively improve oil-gas separation efficiency.And the lubricant oil separated will flow back into along the warped boar 42 of flow apron 4 housing 1 bottom.
Therefore, the utility model embodiment is by flow apron 4 is set above the relief opening at stator 31, thereby makes while telling oily phenomenon, effectively makes lubricant oil separate from the Oil-gas Separation thing, thereby improved oil-gas separation efficiency.And the lubricant oil separated will flow back into along the warped boar 42 of flow apron 4 housing 1 bottom, thereby improved oil return efficiency.
In conjunction with reference to Fig. 2 and Fig. 3, the structural representation of connecting plate in the second embodiment of the utility model rotary compressor is proposed.On the basis of above-described embodiment, the outward edge of described connecting plate 41 is provided with at least one breach 43, and this breach 43 forms through hole jointly with corresponding housing 1 internal face.Certainly, can also be provided with the through hole that at least one connects connecting plate on the connecting plate in the present embodiment 41.
Due to gas mixture stopping through flow apron 4, and occur to flow to, turn back, more oil particles clash into after except being adsorbed on flow apron 4, also may be adsorbed near the wall of housing 1, therefore the flow apron 4 that has warped boar 42 can effectively be assembled the lubricant oil of upper body 1 adsorption, and smoothly the lubricant oil flowed downward can accurately be flow back into to housing 1 bottom by the through hole of flow apron 4, further improved oil return efficiency.
Further, described connecting plate 41 is fixed on the internal surface of the housing 1 between compressor exhaust pipe 6 lower end surfaces and stator iron core 311 upper-end surfaces, and the warpage of described warped boar 42 is towards outlet pipe 6.This flow apron 4 is arranged on the correct position between outlet pipe 6 and motor 3, can reach the purpose of effectively lubricant oil being separated from gas mixture, can not hinder again the discharge of cold media air.And the warpage of this warped boar is towards outlet pipe 6, can be so that the lubricant oil be adsorbed on flow apron 4 can successfully flow to housing 1 bottom from connecting plate.
With reference to Fig. 4, the 3rd embodiment's of the utility model rotary compressor structure is proposed.The connecting plate 41 of described flow apron 4 comprises assembly department 411 and transition part 412, and flow apron 4 is fixed on the internal surface of housing 1 by assembly department 411.This assembly department is that transition part 412 outward edge outwards extend to form, and the internal surface of the outer side wall of assembly department 411 and housing posts and fixes.By assembly department 411, increased the area of contact of joint 41 with housing 1, thereby made joint 41 more stable with being connected of housing 1.
In conjunction with reference to Fig. 4 and Fig. 5, the 4th embodiment's of the utility model rotary compressor structure is proposed.On the 3rd embodiment's basis, also be provided with at least one breach 43 on this embodiment's assembly department 411, this breach 43 forms through hole jointly with corresponding housing 1 internal face.Can certainly be provided with through hole in assembly department 411 and the joint of transition part 412.
With reference to Fig. 6 and Fig. 7, Fig. 6 is the 5th embodiment who proposes on the second embodiment's basis, and Fig. 7 is the 6th embodiment who proposes on the 4th embodiment's basis.In the 5th embodiment and the 6th embodiment, the bottom of flow apron 4 is equipped with and is connected with described flow apron 4 through holes and is the pipeline 5 of individual components, and this pipeline 5 extends to the side of motor 3 near compressing mechanisms 2 always.This pipeline 5 can limit the flow direction of lubricant oil, makes lubricant oil on flow apron 4 can flow to rapidly the bottom of housing 1.
With reference to Fig. 8 and Fig. 9, Fig. 8 is the 7th embodiment who proposes on the second embodiment's basis, and Fig. 7 is the 8th embodiment who proposes on the 4th embodiment's basis.In the 7th embodiment and the 8th embodiment, the pipeline 5 in this embodiment includes the connecting tube 51 of the ventilation breach 312 be arranged on stator iron core 311 and the ventilation breach 312 that is connected flow apron 4 through holes and stator iron core 311.In this embodiment, utilize the ventilation breach 312 on stator iron core 311 to form pipeline 5, thereby saved the cost of pipeline 5.
Further, described flow apron 4 can be made into a body component with connecting tube 51.
The foregoing is only preferred embodiment of the present utility model; not thereby limit its scope of the claims; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
