Description
Technical field
The utility model relates to the compressor that is used for the household electrical appliances electric refrigerator, the piston slip pipe formula compressor of a kind of miniaturization specifically.
Background technique
Compressor is to be used for convection cell, such as refrigeration agent or air, compresses, and by a relief opening compressed fluid is discharged, and is used for purposes such as refrigeration and chemical process, uses very extensive.
The compressor that the utility model relates to is the light duty compressor of a kind of refrigerating capacity at 41W～52W.Light duty compressor is used for the household electrical appliances refrigeration product more, and as small refrigerator, compressor cooling drinking machine, small type ice cube maker etc., compressor has the advantages that refrigerating capacity is little, the overall volume size is little, noise is low.
In traditional light duty compressor, usually adopt rotary compressor, relate to a kind of miniature rotary compressor as disclosing a kind of light duty compressor among the Chinese invention patent CN1143061C, variation by enclosed volume comes air is compressed this kind compressor by wobbler action, thereby in less space, produce pressurized air, this compressor can become small-sized and weight is lighter, so that can be installed in the air conditioner.But the manufacture cost of rotary compressor is higher, and rotary vane also is easier to damage, and operating cost is higher.
Summary of the invention
The purpose of this utility model is: in order to address the above problem, provide a kind of size little, convenient use, the small-sized piston slip pipe formula compressor that is easy to produce.
The technical solution of the utility model is:
A kind of small-sized piston slip pipe formula compressor; include the housing that loam cake and lower casing are formed; be installed with fixing frame on the housing; base plate; starter and protector; relay cover; earth stud also is installed in outside; cylinder block is installed in housing; piston assembly; transmitting assemblies; motor; cylinder head; suck and exhaust pipe assembly; cylinder block is installed in the housing; piston assembly is installed in the cylinder block and cylinder head is formed cylinder; transmitting assemblies is given piston assembly with the transmission of power of motor output; suction and discharge means are communicated with suction and the relief opening on cylinder and the housing respectively, and it is characterized in that: compressor top cover and lower casing pass through CO
2The protection solid welding is tightly connected surely; spring bracket is installed in the housing; spring is installed on the support; motor and crankcase are fixed together; crankcase is fixed on the spring; the rotatingshaft of motor vertically is installed in the housing fixedlys connected with bent axle; the crank throw place of bent axle is set with crosshead; crosshead is enclosed within the slip pipe and can be free to slide; be fixed with the piston body vertical on the slip pipe with slip pipe; hole and cylinder block and head that piston body passes on the cylinder block are formed cylinder, are fixedly mounted on the crankcase jointly after cylinder block and head is fixed together.
Supplementary technology scheme of the present utility model:
Piston body is the hollow circular cylinder of 2mm steel plate stretch forming.
The beneficial effects of the utility model are: owing to adopt the slip pipe structure, that crankshaft eccentric can be made is littler, and structure is more compact, and other piston rod formula compressors are more reliable at present for performance, zero, the component processing required precision is not high, is easy to assembling and carries out mass production.
