The structure of existing rotary compressor comprises generally as shown in Figure 1: housing 1, be arranged in the housing 1 and have running shaft 4 and mechanical structure portion, motor driving part and the compressor arrangement portion of the compressor of eccentric part.Wherein, described motor driving part comprises: be arranged on the motor stator 2 and the rotor 3 of the inside of housing 1, the center of described rotor 3 is pressed into and is installed on the running shaft 4; Described press part comprises: be fixedly installed on circular cylinder 5 on housing 1 inner peripheral surface, be arranged on the eccentric part of running shaft 4 and under the effect of running shaft 4 in cylinder 5 ring 7 and one end that rolls of eccentric rotation be crimped on the outer circumferential face that rolls ring 7, the other end contacts with baffle plate spring (not shown), and is rolling the baffle plate 8 of doing straight line motion when ring 7 is rotated motion and cylinder 5 being divided into breathing space and compression volume; Described mechanical structure portion comprises: the upper bearing (metal) 6A and the lower bearing 6B that are close to the upper and lower both sides of cylinder 5 respectively, and being installed in baffler 9 on the relief opening (not shown) of upper bearing (metal) 6A, described running shaft 4 connects upper bearing (metal) 6A and lower bearing 6B and is supported by them.In addition, also be provided with gas-liquid separator 10 in a side of housing 1, gas-liquid separator 10 is connected on the suction port of cylinder 5.
The working procedure of above-mentioned rotary compressor is as follows:
Give stator 2 power supplies, make the inner rotation of rotor 3 at stator 2, meanwhile running shaft 4 rotates and piston 7 off-centre in cylinder 5 is rotated, off-centre rotation along with piston 7, refrigeration agent is inhaled into the breathing space of cylinder 5, and continues to be compressed to certain pressure, when the pressure in the compression volume of cylinder 5 surpasses critical pressure, the drain tap that is installed on the relief opening of upper bearing (metal) 6A is opened, and pressurized gas drains in the housing 1 through drain tap and baffler 9 from compression volume.The gas of discharging enters into the top of rotary compressor by the slit between the slit between housing 1 and the stator 2 or stator 2 and the rotor 3, passes through gas outlet pipe DP then and is discharged to the circulating frozen system.
But there is following shortcoming in existing rotary compressor:
Distance is bigger between compressor top cover and the motor lines bag, and the discharge tube of compressor stretches out from the top of loam cake, causes the whole height of compressor higher, occupation space is big, not only increased noise, also limited its application area.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rotary compressor of compact structure.
The objective of the invention is to be achieved through the following technical solutions:
A kind of rotary compressor, comprise: housing, be arranged on the press part that cold media air compressed in the housing, be used for the motor of drive compression portion work and be arranged on tenminal block and the outlet pipe that covers, the loam cake of described housing is arranged on the position near the motor lines bag, the lower end of loam cake is welded on the outer circumferential face of housing upper end, and described outlet pipe and tenminal block are arranged on the side of loam cake.
The described loam cake one side position relative with the motor lines bag forms the boss of outside protrusion, and described tenminal block is arranged on described boss place; Described outlet pipe is arranged on a side relative with tenminal block.
The present invention can also be arranged on described tenminal block the side that motor lines is wrapped the compressor top cover of portion, and the opposite side of described loam cake reaches the part of going up tops and is recessed to form concave surface downwards; Described outlet pipe is arranged on contiguous tenminal block place, loam cake side.
Rotary compressor of the present invention is arranged on the side of compressor top cover with the outlet pipe of the tenminal block of motor and compressor, has reduced the local height/whole height of compressor, has reduced the shared space of compressor.

Embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to rotary compressor of the present invention.
At first as Fig. 3 and shown in Figure 5, rotary compressor of the present invention and existing rotary compressor structure are basic identical, comprising: be arranged in the housing 21 and have the compressor of eccentric part running shaft 24, the press part that is used for cold media air is compressed, be separately positioned on press part the upper bearing (metal) 26A of both sides and lower bearing 26B and the motor driving part that is used for drive compression portion up and down.Wherein, described press part comprises: be fixedly installed on circular cylinder 25 on housing 21 inner peripheral surfaces, be arranged on the eccentric part of running shaft 24 and under the effect of running shaft 24 in cylinder 25 ring 27 and one end that rolls of eccentric rotation be crimped on the outer circumferential face that rolls ring 27, the other end contacts with baffle plate spring (not shown), and is rolling the baffle plate 28 of doing straight line motion when ring 27 is rotated motion and cylinder 25 being divided into breathing space and compression volume.Described motor driving part comprises: be arranged on the motor stator 22 and the rotor 23 of the inside of housing 21, the center of described rotor 23 is pressed into and is installed on the running shaft 24.The loam cake 30 of rotary compressor housing 21 is arranged on the position near motor lines bag 29, and the lower end of loam cake 30 is welded on the outer circumferential face of housing 21 upper ends.
In addition, referring to Fig. 2, first embodiment of the present invention shown in Figure 3.In this embodiment, contiguous motor lines bags 29 of loam cake 30 and being provided with, the relative side of loam cake 30 and motor lines bag 29 is outside protrusion radially, form boss 31, form certain spaces in the boss 31, tenminal block 32 is arranged on boss 31 places, and outlet pipe 33 is arranged on a side relative with tenminal block 32.Certainly, also can as required tenminal block 32 be arranged on other suitable location of loam cake 30 sides.
Fig. 4, Figure 5 shows that an alternative embodiment of the invention.As shown in the figure, tenminal block 32 is arranged on a side of motor lines bag 29 tops, compressor top cover 30, the opposite side of loam cake 30 reaches the part of going up tops and is recessed to form a concave surface 34 downwards, and concave surface 34 can be an arc-shaped concave, also can be designed to the concave surface of other shape as required.The outlet pipe (not shown) is arranged on the side of loam cake 30, can be at contiguous tenminal block 32 places, also can be in the loam cake side other suitable position.
The working procedure of rotary compressor of the present invention is as follows:
Give stator 22 power supplies, make the inner rotation of rotor 23 at stator 22, meanwhile running shaft 24 rotates and piston 27 off-centre in cylinder 25 is rotated, off-centre rotation along with piston 27, cold media air is inhaled into the breathing space of cylinder 25, and continue to be compressed to certain pressure, when the pressure in the compression volume of cylinder 25 surpasses critical pressure, the drain tap that is installed on the relief opening of upper bearing (metal) 26A is opened, and compressed cold media air drains in the housing 21 through drain tap and baffler 29 from compression volume.The gas of discharging enters into the top of rotary compressor by the slit between the slit between housing 21 and the stator 22 or stator 22 and the rotor 23, passes through outlet pipe 33 then and is discharged to the circulating frozen system.Because the tenminal block of motor and the outlet pipe of compressor are arranged on the side of compressor top cover, so reduced the local height/whole height of compressor, have reduced the shared space of compressor.In addition, because the cold media air ingress of outlet pipe 33 is not the oil outlet that directly faces toward running shaft 24, so the cold media air of discharging can not carry away a large amount of lubricant oil, can avoid the decrease in efficiency problem that too much causes owing to the oil in the air-conditioning whole system like this.
