Description
The (1) technical field: the utility model relates to the improvement technology of hermetically sealed compressor, especially a kind of exhaust noise silencing chamber independence suspension type hermetically sealed compressor.
(2) background technique: traditional totally-enclosed reciprocating piston linkage type refrigeration compressor; (referring to Fig. 1) includes housing 8; Cylinder block 5, motor 11 are installed in housing, and air-breathing silencing cavity 10 is equipped with bent axle piston crank mechanism 9 in cylinder block; Valve group assembly 3 and cylinder head 1 are equipped with in the cylinder head outer end of cylinder block; Its structural feature mainly is to be connected through the exhaust passage 4 on the valve plate in the hyperbaric chamber passage 2 on the cylinder head 1 and the valve group assembly 3, and the exhaust passage 4 on the valve plate links to each other with exhaust passage on the cylinder block 5, and the exhaust passage on the cylinder block 5 is communicated with exhaust noise silencing chamber 6 on being arranged on cylinder block; Then, be interlinked to the outside with shell through the high pressure coil pipe 7 that is built up in the exhaust noise silencing chamber.Be cast with the exhaust noise silencing chamber 6 of one on the cylinder of compressor seat 5 of conventional construction, because compressor is after the refrigeration agent compression, the exhaust valve plate of the high temperature and high pressure gas of generation from valve group assembly 3 is discharged to cylinder head 1; Through the exhaust passage on valve plate and the cylinder block 5 refrigeration agent is discharged in the exhaust noise silencing chamber 6, because the compressor continuous operation, exhaust noise silencing chamber 6 is cast as one with cylinder block 5 again again; The heat of the heat that produces when making the cylinder head compression and the gas of discharge all is accumulated on the cylinder block 5, and cylinder block 5 is metal partss, and it constantly passes to the refrigeration agent in the housing with heat; Cause the refrigerant gas heating, motor 11 also can produce higher heat, makes that the compressor temperature inside is high; The gas that enters into compressor is like this heated by internal heat resource, and compressor just sucks very hot gas when air-breathing, because gas heat increases; The density of gas must descend; The refrigerant quality that compressor is drawn in the cylinder will reduce, and the gas flow of compressor compresses also reduces, thereby the quality of feasible refrigeration agent of discharging reduces; Make compressor under the situation that consumes a large amount of merits; Do not bring into play higher refrigeration, the refrigeration of compressor is just relatively poor like this, and efficient is lower.
The (3) summary of the invention: the purpose of the utility model will overcome existing refrigeration compressor exactly and be provided with grate flow channel, easily heat exchange phenomenon takes place because of cylinder block; Cause that compressor gas heat when air-breathing increases; Thereby influence the refrigeration of compressor and the problem of efficient, a kind of exhaust noise silencing chamber independence suspension type hermetically sealed compressor is provided.
Concrete scheme of the present invention is: improve to existing hermetically sealed compressor, it includes housing, and cylinder block, motor are installed in housing; Air-breathing silencing cavity; The bent axle piston crank mechanism is housed in cylinder block, and valve group assembly and cylinder head are equipped with in the cylinder head outer end of cylinder block, it is characterized in that: on cylinder head, have an exhaust port; Over against the exhaust port of the cylinder head cantilever type connecting tube that has been welded; The exhaust noise silencing chamber that independently suspends that is welded, the outer end of connecting tube has inlet hole and is communicated with connecting tube on the exhaust noise silencing chamber, and has air outlet hole and connect outlet pipe.
The said cylinder head of the utility model is to adopt the thick steel plate of 1.5～4mm to be stamped to form, and dashing on the cylinder head has re-entrant cavity, cylinder head to adopt four jiaos of four bolts arranging to be contained on the cylinder head of cylinder block.
The said connecting tube wall thickness of the utility model is 0.6～1.5mm, and external diameter of pipe is 3～9 mm.Tubing is iron pipe or steel pipe or Bandaid pipe.
The utility model is compared with traditional compressor, through the exhaust noise silencing chamber being arranged in the structure beyond the cylinder block, can significantly reduce the heat transfer of compressor when work.Because original exhaust noise silencing chamber cancellation on the cylinder block makes the weight of cylinder block be able to reduce, and after the cancellation of the exhaust noise silencing chamber of cylinder block; The only surplus next cylinder end face of cylinder block because the both sides of cylinder block have not had the exhaust noise silencing chamber, will reduce with the material that leans on both sides on the cylinder-bore axis; Can the line bag of stator be leaned on cylinder block to reduce the upwards upset of direction of material, can the bag that roll off the production line of stator highly can be reduced like this, the height of whole movement is reduced; Can extremely save the integral material of compressor greatly; Behind the cancellation exhaust noise silencing chamber, the chance that the refrigerant gas that can let compressor discharge contacts with cylinder block has reduced on the cylinder block, can reduce hot gas and the exchange that gets into the inner cold air of compressor; Improve refrigeration, can let the thermal efficiency of compressor be greatly improved simultaneously.
