Compression mechanical part 10 is made up of cylinder, upper bearing (metal), lower bearing and baffler;
Refrigerant gas is sucked by the suction tude 11 of housing lower end, is discharged by the outlet pipe 3 of loam cake 4 after overcompression, and outlet pipe 3 is discharging refrigerant gas upward.Tenminal block 2 and outlet pipe 3 are installed on the loam cake 4.The power line that tenminal block is introduced inserts mechanism portion by the top.
There is following problem in the rotary compressor of prior art: because tenminal block 2 and outlet pipe 3 be installed on the loam cake 4, so compressor overall height height, installation footprint is big, and vibration is big, noise is big.
Summary of the invention
The present invention proposes in order to overcome the shortcoming that exists in the prior art, purpose provides and a kind ofly at the housing upper side outlet pipe and tenminal block is set, and can reduce the compressor overall height, reduces vibration and noise, the upper side exhaust structure of the hermetic type compressor of compact structure.
Technological scheme of the present invention is: a kind of upper side exhaust structure of hermetic type compressor, described compressor comprise seal container, be installed in the mechanism portion on seal container top and be installed in the compression mechanical part of seal container bottom.Seal container is made up of loam cake, housing and lower cover; Mechanism portion is made up of stator, the rotor that is installed in stator center and running shaft; Compression mechanical part is made up of upper bearing (metal), lower bearing, cylinder and baffler.
Cylindrical upper side at described housing is provided with the boss that a centre has elliptical aperture, the profile of boss is oval, one end of boss links to each other with the upper side of housing by welding, the other end of boss is connected with mounting plate by welding, the tenminal block of power supply and outlet pipe are installed on the mounting plate, one end of outlet pipe inserts the inside of housing, and the other end leads to the outside of housing.Mounting plate is to have certain thickness sheet material, and its profile is oval.
Cylindrical upper side at described housing is provided with a round-meshed boss in centre, and the profile of boss is circular, and mounting plate is to have certain thickness sheet material, and its profile is circular.Described mounting plate is installed on the boss by screw.Be provided with sealing gasket between described boss and the mounting plate.
The present invention has reduced the compressor overall height because tenminal block and outlet pipe are connected the upper side of compressor housing, and compact structure has reduced vibration and noise simultaneously.Because the upper side at the housing cylindrical is provided with boss, makes the wiring of tenminal block and motor section line bag convenient, outlet pipe also has bigger space to store the gaseous coolant of the High Temperature High Pressure that was compressed.
