Embodiment
Followingly the present invention is carried out detailed explanation with reference to accompanying drawing and embodiment.The parts identical with existing technology have used identical symbol among the present invention.
The protective cover structure of overload of compressor protector of the present invention; Be applied to hermetic rotary compressor; The rotary compressor main structure includes the seal container that inside is formed with the sealing holding space; In sealed container interior the mechanism portion that the running shaft that combines on rotor and the rotor of stator, the stator center of packing into is formed, the compression mechanical part that combines with the running shaft lower end are installed.Seal container is made up of the circular shell of centre, the loam cake that is connected the housing upper end and the lower cover of housing lower end.
Mechanism portion is arranged on the upside of housing and produces rotating force; Compression mechanical part is arranged on the downside of enclosure interior and is utilized in the rotating force compressed refrigerant that mechanism portion produces.
Mechanism portion is made up of stator and rotor, stator be fixed on the inside of housing and from the outside by power supply terminal 8 turn-on powers, rotor interior one fixed gap of stator install and with the interactional rotation simultaneously of stator.
Compression mechanical part is made up of cylinder, upper bearing (metal), lower bearing and baffler;
Refrigerant gas is sucked by the suction tude of housing lower end, after overcompression, is discharged by the outlet pipe of loam cake, and outlet pipe is to top discharging refrigerant gas.Tenminal block 8 is installed on the loam cake 5 with outlet pipe.The power line 6 that tenminal block is introduced inserts mechanism portion by the top.
Fig. 4 is the exploded view that is installed in the compressor top cover parts of the present invention.
As shown in Figure 4; Be provided with overload protective device 3, tenminal block 8 and the erection column 4 of mechanism portion at compressor top cover 5; For the tenminal block and the overload protective device of protection compressor are avoided drenching with rain, Exposure to Sunlight, also be provided with protective cover 11 last covering, tenminal block 8 and overload protective device 3 covers are got up.
The erection column lower end is connected and covers, and the protective cover top is passed in the upper end, and is by nut 1 that protective cover and erection column is fastening.The height of erection column 4 is to exceed to connect protective cover 2 and nut height.Erection column 3 both sides are equipped with overload protective device 3, tenminal block 8.Power line 6 is connected with tenminal block 8 with overload protective device 3.
Fig. 5 is a protective cover plan view of the present invention; Fig. 6 is the B-B sectional view of Fig. 5.
Like Fig. 5, shown in Figure 6; The hollow lid 9 that protective cover 11 of the present invention is formed by connecting two highly different cylinders is provided with positioning hole 10 at two cylinder connection parts of lid, erection column 4 by positioning hole 10 through and stretch out; The erection column upper end is shaped on screw thread, and nut 1 is fastened on the screw thread.Erection column is processed by metallic material, good heat conductivity.The positioning hole diameter is greater than the erection column external diameter, less than the nut external diameter.The positioning hole diameter can guarantee like this that greater than the erection column external diameter erection column passes through.
Below the positioning hole 10 of above-mentioned lid 9, be formed with the thermal insulation protection cover 12 of hollow.Described thermal insulation protection cover 12 is integrally formed with lid 9.The upper end of thermal insulation protection cover 12 is connected with positioning hole, and the lower end is open, and there is cavity the centre of thermal insulation protection cover 12, is hollow article.
The internal diameter of described thermal insulation protection cover is greater than the erection column external diameter, is convenient to the outside that thermal insulation protection cover 12 on the protective cover 11 can successfully be installed to erection column.The thermal insulation protection cover is kept apart erection column and power line, and power line does not directly contact erection column.
Described thermal insulation protection cover adopts heat-resistant material to process.There is certain distance the lower end of described thermal insulation protection cover apart from the lid lower plane.
The installation method that the present invention has the protective cover of thermal insulation protection cover is: earlier the positioning hole of protective cover is aimed at the erection column top; Again erection column is inserted in the lower end of thermal insulation protection cover; Protective cover is moved down, and erection column passes the positioning hole above the protective cover, moves to the protective cover lower plane and drops on plane on the compressor top cover; At last with nut screwing clamping on the screw thread of erection column upper end, installation.
Because the present invention is with the thermal insulation protection cover in the outside of erection column; The thermal insulation protection cover adopts heat-resistant material to process; Therefore the power line exocuticle does not directly contact with the erection column of being processed by metallic material and heat conduction is good, and the heat that erection column distributes can not make the power line exocuticle melt.Thereby a series of accidents that electric leakage take place and cause have been prevented by the thawing of being heated of power line epidermis.
