Description
Technical field
The invention belongs to a kind of hermetic type compressor, be specifically related to a kind of reservoir structure of hermetic type compressor.
Background technology
As shown in Figure 1, 2, the compressor of prior art, the upper inside that is included in housing 10 is equipped with electric machine assembly 20, at the downside of electric machine assembly 20 compressor assembly 30 that is equipped with separated by a distance.Housing 10 is by cylindrical drum 11, the loam cake 12 of hollow and go to the bottom and 13 etc. form.Electric machine assembly 20 is pressed on the inner peripheral surface that is fixed on cylindrical shell 11, and it is made up of stator 21, rotor 22 and rotary crankshaft 23 of being pressed into the center that is fixed on rotor 22 and transmitting revolving force etc.
In addition, be provided with outlet (not shown) in the upper bearing 32, its upside binding is fixed with muffler 34, is used to reduce the noise that is produced by pressure differential from the compressed media gas of outlet discharge.For making dielectric gas be discharged to seal casinghousing 10 outsides by muffler 34, on loam cake 12, be provided with discharge pipe 16, on loam cake 12, also be provided with the binding post 17 that connects power line.
Side at seal casinghousing 10 is provided with reservoir 14, and reservoir 14 comprises cylindrical shell 41, is provided with suction line 42 in the inside of cylindrical shell 41, is communicated with suction elbow 15 in suction line 42 lower ends.Be provided with tube connector 43 in the upper end of cylindrical shell 41, the certain distance on suction line 42 tops is provided with the support 44 that supports screen pack, is provided with screen pack 45 on support 44.
Shown in Fig. 3～7, support 44 forms the disc-shaped part with arcuate convex in the middle of being, support 44 comprises body 46, has arcuate convex 47 in the centre of body 46, excircle in arcuate convex 47 forms a plurality of equally distributed sorting holes 48, is provided with the block cover 49 of bowl-type in the lower end of each sorting hole 48.
The flow through process of reservoir 14 of hermetic type compressor of prior art of the gas-liquid mixture of refrigerant is: the gas-liquid mixed refrigerant is by the sorting hole on screen pack and the support, because stopping of the block cover of bowl-type, the gas-liquid mixed refrigerant can not directly enter suction line 42, has prevented to produce in suction line liquid hit phenomenon.Therefore, the gas-liquid mixed refrigerant enters the bottom of reservoir 14, and the liquid state in the gas-liquid mixed refrigerant is sunk, and gaseous state rises and enters suction line from the upper end open of suction line, and the suction muffler that enters compresser cylinder through suction elbow is finished breathing process.
But, in the structure of the hermetic type compressor reservoir of prior art,, screen pack could be supported owing to support must be set in the bottom of screen pack.But, the structure more complicated of support, as support is the middle disc-shaped part with arcuate convex that forms, and has arcuate convex again in the centre of rack body, excircle in arcuate convex forms a plurality of equally distributed sorting holes again, is provided with the block cover of bowl-type in the lower end of each sorting hole.Because the structure structure more complicated of support needs through multiple working procedure, and processing difficulties, waste time and energy, production efficiency is low.
Summary of the invention
The present invention is for the shortcoming that overcomes prior art proposes, and its objective is the reservoir structure that a kind of simple in structure, hermetic type compressor that production efficiency is high is provided.
Technical scheme of the present invention is: a kind of reservoir structure of hermetic type compressor, and described compressor comprises housing, housing is made up of cylindrical drum, loam cake and the lower cover of hollow, in the upper inside of housing electric machine assembly is installed.At the downside of the electric machine assembly compressor assembly that is equipped with separated by a distance.
Side at seal casinghousing is provided with reservoir, and reservoir comprises cylindrical shell, upper cover and low head.Form tongue and groove on cylindrical shell top, be provided with support, on support, be provided with screen pack on the inside of cylindrical shell, the top of tongue and groove.Inside at cylindrical shell is provided with suction line, the top closure of suction line, and the tube wall side of certain distance forms plural air inlet below the top of suction line, and the lower end of suction line is communicated with suction elbow by pipe joint.
Described tongue and groove is that the outer wall of cylindrical shell concaves, inwall is to the tongue and groove of the circumferential of convex.Support is to have the metal of certain width and thickness or the annulus of plastics.
Reservoir of the present invention is simple in structure, easy to make, the saving material, has improved production efficiency, has reduced product cost.
