Motor is made up of 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, directly is pressed into the upper end of bent axle 6 and inserts in the cylinder cavity of stator iron core, has air gap to be separated by between rotor 5 and the stator 4.Embed the winding of enameled cable coiled on the stator 4, staor winding outside source current by the time produce magnetic field.When rotor 5 has electric current to pass through,, produce electromagnetic torque and in stator 4, rotate 6 rotations of rotor 5 drive bent axles with the magnetic field interaction of stator 4.Bent axle 6 inserts in the cylinder 8 of the pump housing, and the off-centre of bent axle 5 lower ends turns is overlapping the rolling rotor 12 that is arranged in the cylinder cavity on 11.
The pump housing comprises main bearing 7, lower bearing 9 and cylinder 8.Main bearing 7 and lower bearing 9 are made to be formed with the cylinder cavity in the cylinder 8 by the both sides up and down that are bolted to cylinder 8.Rolling rotor 12 is set in the cylinder cavity, and rolling rotor 12 is enclosed within the off-centre of inserting bent axle 6 lower ends in the cylinder 8 and turns on 11.The rotation of bent axle 6 drives rolling rotor 12 and rolls along cylinder wall surface in cylinder 8, realizes entering the compression and the exhaust process of cylinder cavity inner refrigerant.
Fig. 2 is the cross-sectional view of the rolling rotor type compressor pump housing.Fig. 3 (3a, 3b) shows the interior baffle arrangement of rolling rotor type compressor pump housing piston of prior art.
As shown in Figures 2 and 3, cylinder wall one side has the groove 17 of a break-through, and baffle plate 13 is housed in the cylinder groove 17, and a side of baffle plate 13 props up rolling rotor 12 outer peripheral surfaces, between another side of baffle plate 13 and the cylinder groove end wall spring 14 is set.Have spring eye 15 on the side end face 21 that spring 14 1 sides are set of baffle plate 13, an end of spring 14 places in the spring eye 15.Along with rolling rotor 12 rolling along cylinder wall surface under turning crankshaft 5 drives, baffle plate 13 is engaged in the cylinder with rolling rotor 12 and slides, under the effect of spring force, closely contact and form motive sealing with rolling rotor 12 excircle walls, crescent shape cylinder chamber body space between rolling rotor 12 and the cylinder wall is divided into air-inlet cavity and compression chamber, at rolling rotor 12 in the process that cylinder axis rotates a circle, air-inlet cavity is finished intake process, compression chamber is finished compression process, and the low-temperature low-pressure refrigerant gas compression that sucks in the cylinder cavity is become high-temperature high-pressure refrigerant gas and discharge.
The air-inlet cavity and the slip of the baffle plate between the compression chamber 13 in cylinder groove that do not wait for pressure keep stable, and spring 14 adopts large diameter spring, and its diameter is greater than the width of baffle plate side end face 21.The spring eye 15 of baffle plate side end face 21 strides across the dual-side of baffle plate 13, expands the two side of cylinder groove 17 to.The two side of the cylinder groove 17 of internal baffle 13 has groove, the part that the spring 14 that stretches with baffle plate 13 slips surpasses baffle plate side end face 21 width can move in the groove of cylinder groove two side, thereby makes the slip of baffle plate 13 in cylinder groove 17 keep smooth and easy and stable.
But, compressor baffle structure for above-mentioned prior art, because the spring eye 15 of baffle plate side end face 21 strides across the dual-side of baffle plate 13, expand the two side of cylinder groove 17 to, so the spring eye 15 that the high-temperature high-pressure refrigerant gas in the cylinder compression chamber can be by baffle plate side end face 21 and the groove of cylinder groove 17 two sides are to the air-inlet cavity internal leakage.The leakage of cylinder inner refrigerant gas can cause the efficient of compressor to lower and decreased performance.
Summary of the invention
Spring eye and the groove of the cylinder groove two side problem of leaking of the refrigerant gas that exists at the compressor baffle connecting structure of above-mentioned prior art by the baffle plate side end face, the utility model is released new compressor baffle connecting structure, its objective is a plurality of little springs arranged side by side in the rectangle groove that employing has on the baffle plate side end face, with the spring eye of eliminating the baffle plate side end face that to be communicated with and the groove of cylinder groove two side, reduce the leakage of refrigerant gas.
The compressor baffle connecting structure that the utility model is related is included in the baffle plate that has rectangle groove on the side end face and a plurality of little springs arranged side by side.The horizontal width of rectangle groove is less than the horizontal width of baffle plate side end face, and an end of little spring is arranged side by side in the baffle plate rectangle groove.The improved compressor baffle connecting structure of the utility model, eliminate on the baffle plate side end face and stride across two baffle plate sides and expand the spring eye of cylinder groove two side to, eliminate the groove that the cylinder groove two side has, the leakage of the refrigerant gas of avoiding the connection of baffle plate side end face spring eye and cylinder groove sidewall notches and producing, the operational efficiency of promoting compressor.Simultaneously, adopt a plurality of little springs arranged side by side, make the slip of baffle plate in cylinder groove keep smooth and easy and stable, help improving the service behaviour of compressor.
