Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Below in conjunction with Fig. 2 and Fig. 3 the embodiment one of the utility model is described.
The embodiment one of the utility model provides a kind of compressor; It comprises housing 10 and is arranged on the drive motors of housing 10 inside; Said drive motors comprises stator 20 and the rotor that cooperatively interacts; On the outer wall of said stator 20, be provided with the stator circulation groove 201 that supplies cold-producing medium to pass through, the tangent line of said stator circulation groove 201 and stator 20 axial A-A formation angle theta, the scope of said angle theta is: 0 ° of < θ≤60 °; So that refrigerant gas is when flowing through stator circulation groove 201 from bottom to top; The circulating direction of refrigerant gas changes, and becomes oblique rising straight up by original, and refrigerant gas constantly collides the inwall of stator circulation groove 201 and the inwall of housing 10 when oblique rising; The lubricating oil droplet that mixes in the refrigerant gas is sticked on the inwall of stator circulation groove 201 and housing 10; The lubricating oil droplet constantly rolls up big drop and flows in the oil sump of compressor at the inwall along stator circulation groove 201 and housing 10 under the effect of gravity, thereby the lubricating oil that is mixed with in the cold-producing medium is separated, and then improves refrigeration.Usually the value of angle theta is big more, stator circulation groove 201 compared to the circulation groove of stator 20 axially parallels, its length is longer; Make in the process of circulation of cold-producing medium in stator circulation groove 201 that is mixed with lubricating oil resistance big more; The time that the cold-producing medium that is mixed with lubricating oil is stopped in stator circulation groove 201 is longer, make the separating effect of lubricating oil better, but the value of angle theta is big more; The gross area of the stator circulation groove 201 on the stator 20 is big more; Stator 20 is more little with the assembling contact area of housing 10, considers the assembling intensity of housing and stator, and the scope of said angle theta is preferably: 30 °≤θ≤60 °.In this angular range, stator circulation groove 201 can separate the lubricating oil in the refrigerant gas preferably, and can guarantee the assembling intensity between stator 20 and the housing 10.The quantity of said stator circulation groove 201 is at least 2, and in the present embodiment, the quantity of stator circulation groove 201 is 6, and said stator circulation groove 201 equidistance on stator 20 is arranged.The cross-sectional area of said stator circulation groove 201 depends on the required amount of cold-producing medium circulation, and the cross-sectional flow area sum of stator circulation groove 201 is got final product greater than the required amount of cold-producing medium circulation.Said stator circulation groove 201 connects whole stator 20.
The advantage of the utility model embodiment one is; On the outer wall of the stator of compressor, be provided with the stator circulation groove that supplies cold-producing medium to pass through; The tangent line of said stator circulation groove and stator shaft orientation form certain included angle θ, the refrigerant gas circulating direction are changed, by becoming oblique rising straight up; Refrigerant gas constantly collision stator circulation groove inwall and inner walls during oblique rising in the stator circulation groove; The lubricating oil viscosity that is mixed with in the refrigerant gas is attached on circulation groove inwall and the inner walls, thereby realizes the lubricating oil that is mixed with in the refrigerant gas is separated, improve refrigeration.
Fig. 3 is to shown in Figure 5; Be the utility model embodiment two; It is the further improvement to embodiment one, and the structure of the stator of said compressor is consistent with the stator structure that provides among the embodiment one, and said compressor comprises housing 100 and is arranged on the stator 200 in the housing 100; Shown in Fig. 4; On the outer wall of said stator 200, be provided with the stator circulation groove 2001 that supplies cold-producing medium to pass through, the tangent line of said stator circulation groove 2001 and stator 20 axially form angle, also are provided with the housing circulation groove 1001 that supplies cold-producing medium to pass through on the said housing 100.Said housing circulation groove 1001 is opened in the position corresponding with stator 200, and housing circulation groove 1001 cooperates the circulation area that can further increase cold-producing medium with stator circulation groove 2001, improves refrigeration.Housing 100 is that steel plate is through rolling welding fabrication; At first on used sheet material, supply the housing circulation groove 1001 of cold-producing medium circulation with stator 200 cooperation place punch formings; And housing circulation groove 1001 equidistance on sheet material is uniformly distributed with; Then sheet material is rolled welding fabrication, perhaps first casting goes out housing circulation groove 1001, and the sheet material with the place's punching of housing circulation groove rolls and be welded into the opening tubular then; Housing circulation groove with casting is welded on the housing again, accomplishes the assembling of compressor at last with the housing of this shape.In order further to add the separating effect of the lubricating oil that mixes in the heavy refrigerant; Improve refrigeration; The tangent line of said housing circulation groove 1001 and housing 100 axial B-B form angle; The scope of said angle is: 0 °≤α 90 °, so that refrigerant gas is when flowing through housing circulation groove 1001 from bottom to top, the circulating direction of refrigerant gas changes; Become oblique rising straight up by original; Refrigerant gas constantly collides the inwall of stator circulation groove 2001 and the inwall of housing circulation groove 1001 when oblique rising, the lubricating oil droplet that mixes in the refrigerant gas is sticked on the inwall of stator circulation groove 2001 and housing circulation groove 1001, constantly rolls up big drop and flows in the oil sump of compressor at the inwall along stator circulation groove 2001 and housing circulation groove 1001 under the effect of gravity; Thereby the lubricating oil that is mixed with in the cold-producing medium is separated, and then improve refrigeration.Usually the value of angle is big more; The resistance of cold-producing medium in the process of circulation of housing circulation groove 1001 that is mixed with lubricating oil is big more, and the time that the cold-producing medium that is mixed with lubricating oil is stopped in housing circulation groove 1001 is longer, and the separating effect of lubricating oil is better; But the value of angle is big more; Stator 200 is more little with the assembling contact area of housing 100, considers the assembling intensity of housing and stator, and the scope of said angle is preferably: 30 °≤α≤60 °.In this angular range, stator circulation groove 2001 separates the lubricating oil in the refrigerant gas with housing circulation groove 1001 binding energy preferably, and can guarantee the assembling intensity between stator 200 and the housing 100.The quantity of said housing circulation groove 1001 is at least 2, and in the present embodiment, the quantity of housing circulation groove 1001 is 6, and said housing circulation groove 1001 equidistance on housing 100 is arranged.The cross-sectional flow area of said housing circulation groove 1001 depends on the required cross-sectional area of cold-producing medium circulation, and the circulation volume sum of stator circulation groove 2001 and housing circulation groove 1001 is got final product greater than the required cross-sectional area of cold-producing medium circulation.
The utility model embodiment two has additional the housing circulation groove on the basis of embodiment one, it has further improved refrigeration.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
