The closed compressor has the advantages of simple and reasonable structure, high casing strength and bearing capacity, small deformation and firm connection.

Description

Closed-type compressor
Technical field
The utility model relates to a kind of closed-type compressor.
Background technique
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electric appliance of cooling cycle system work, utilize its moving element under driven by motor, rolling rotor or to-and-fro motion words plug etc., change mechanical energy into the pressure energy, realization is to the compression of compresser cylinder inner refrigerant, and refrigerant compressed discharged enters refrigeration cycle.
For some refrigeration agents, as R401A or CO 2Deng, the operating pressure height when it moves in compressor is so need provide compressive strength high seal casinghousing.In the prior art, the opening of the upper shell in the seal casinghousing of common compressor inwardly, the cross section of upper shell is circular-arc, upper shell and tenminal block are fixed by resistance welding.When compressor operating pressure was high, upper shell bore higher interior pressure, occured bending and deformation easily, and caused tenminal block destroyed easily, and then cause leakage.
The model utility content
The purpose of this utility model aim to provide a kind of simple and reasonable, casing rigidity is high, bearing capacity is high, distortion is little, connect firm closed-type compressor, to overcome deficiency of the prior art.
A kind of closed-type compressor by this purpose design, comprise the compression assembly and the electric machine assembly that are arranged in the housing, housing comprises main casing and upper shell, tenminal block is welded on the upper shell, it is characterized in that upper shell is provided with the recess towards the enclosure interior depression, tenminal block is welded in the recess.
Be provided with first pilot hole in the described recess, tenminal block is arranged in first pilot hole, is welded as a whole with upper shell.
Be provided with mounting plate above the described recess, be provided with first pilot hole in the recess, be provided with second pilot hole in the mounting plate, tenminal block is welded in second pilot hole after passing first pilot hole.
Described first pilot hole and second pilot hole are coaxially set.
The aperture of described first pilot hole is bigger than the aperture of second pilot hole.
The utility model upper shell is provided with the recess towards the enclosure interior depression, thereby has improved the intensity of upper shell, has improved the bearing capacity and the non-deformability of upper shell; When tenminal block is welded in the recess, can prevent effectively that tenminal block is destroyed because of the high pressure of enclosure interior, improved the Safety performance of compressor.
In order further to strengthen the intensity of upper shell, and then improve the intensity of whole housing, the utility model also is provided with mounting plate on recess, by this mounting plate recess being carried out the part strengthens, to remedy when the recess perforate, further improved the Safety performance of compressor to the intensity effect of upper shell.
The utlity model has simple and reasonable, casing rigidity is high, bearing capacity is high, distortion is little be connected firm characteristics.
Description of drawings
Fig. 1 is the utility model first embodiment's sectional structure schematic representation.
Fig. 2 is the utility model first embodiment's a broken section structural representation.
Among the figure: 1 is main casing, and 2 is upper shell, and 3 is outlet pipe, and 4 is stator, and 5 is rotor, and 6 is bent axle, 7 is main bearing, and 8 is cylinder, and 9 is supplementary bearing, and 10 is lower shell body, and 11 is rolling rotor, 12 is tenminal block, and 13 is recess, and 13a is first pilot hole, and 14 is mounting plate, and 14a is second pilot hole.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
First embodiment
Referring to Fig. 1, this closed-type compressor, comprise the compression assembly and the electric machine assembly that are arranged in the housing, housing comprises main casing 1, upper shell 2 and lower shell body 10, tenminal block 12 is welded on the upper shell 2, and upper shell 2 is provided with the recess 13 towards the enclosure interior depression, is provided with the first pilot hole 13a in the recess, tenminal block 12 is arranged among the first pilot hole 13a, is welded as a whole with upper shell 2.Also be provided with outlet pipe 3 on the upper shell 2.One end of tenminal block 12 is connected with the motor lighting outlet.
Because tenminal block 12 is among the first pilot hole 13a that is welded on this recess 13 by the resistance welding fusion, so can improve the intensity of upper shell to a certain extent.
In the housing of compressor, compression assembly is arranged on the bottom, the top that electric machine assembly is provided with.
Electric machine assembly comprises stator 4 and rotor 5, and stator 4 and rotor 5 are made of the iron core that the folded collection of silicon steel core sheet forms respectively.Rotor 5 is cylindric, and rotor 5 directly is pressed into the upper end of bent axle 6 and inserts in the cylindrical cavity of stator 4, is provided with air gap between rotor 5 and the stator 4 and is separated by.Be embedded with the winding of enameled cable coiled on the stator 4.Stator 4 outside source current by the time produce magnetic field.
Rotor 5 electric current by the time produce magnetic field, the magnetic field interaction that this magnetic field and stator 4 produce produces electromagnetic torque and also rotates stator 4 in, rotor 5 drives bent axles 6 rotations.
Compression assembly comprises main bearing 7, cylinder 8 and supplementary bearing 9.Main bearing 7 and supplementary bearing 9 are by the both sides up and down that are bolted to cylinder 8, and main bearing 7, cylinder 8 and supplementary bearing 9 surround the cylinder chamber body jointly.The rolling rotor 11 that is provided with in the cylinder cavity is enclosed within on the eccentric shaft that inserts bent axle 6 lower ends in the cylinder 8.The rotation of bent axle 6 drives rolling rotor 11 and rolls along the cylinder inner wall face in cylinder 8, realizes entering the compression and the exhaust process of cylinder cavity inner refrigerant.
Second embodiment
