Abstract
A scroll compressor comprises a compressor casing, a motor, a top plate and a compression unit. The compression unit has a stationary scroll forming a circle housing groove on upper surface thereof. The top plate includes a separating plate and a boss plate connected by a bolt. The separating plate is welded on the compressor casing to separate an intracavity into a first chamber and a second chamber. A guide hole is provided in the boss plate to guide a compressing refrigerant into the first chamber from the compression cavity. A protrusion is provided on lower surface of the boss plate which is capable of inserting into the housing groove. A seal part is equiped between the housing groove side wall and the protrusion. During assembling, centers of the top plate and the stationary scroll are set in a same center line. Accordingly, damage of the seal part and leagage of the refrigerant resulting therefrom are prevented.
Description
The present invention relates to scroll compressor.
That scroll compressor is applied to usually is indoor, the air conditioner in the automobile, also is applied to refrigerator, and this is because it has advantages such as size noise little, in light weight, that produce is little.
Scroll compressor shown in Figure 1A to 1D is to utilize quiet whirlpool dish 10 with relatively rotating of movable orbiting scroll and compression refrigerant, and two whirlpools dishes all have spiral-shaped plate.
Refrigerant by quiet whirlpool dish 10 and movable orbiting scroll 20 compressions charges into the compressor inner chamber earlier, is full of after discharge tube is discharged.
According to above-mentioned needs, compressor is separated into low pressure chamber and hyperbaric chamber with top board.What fill in the low pressure chamber is to prepare the refrigerant of compression and be full of the refrigerant that compressed in the hyperbaric chamber.Compression assembly with quiet whirlpool dish and movable orbiting scroll be installed in top board in the low pressure chamber below.
Such scroll compressor is made brief description hereinafter with reference to Fig. 2.
There are an exhaust port 13 and a safety check receiving part 14 in the central authorities of quiet whirlpool dish 10, and the peripheral inboard of safety check receiving part 14 has an annular to receive groove 15.One safety check 30 is arranged in the safety check receiving part 14, exhaust port 13 is opened or closed.One guide hole 41 is arranged on the top board 40, safety check receiving part 14 is communicated with the hyperbaric chamber.In addition, top board 40 lower surfaces stretch out an annular boss 42, inject in the reception groove 15 of quiet whirlpool dish 10.Also put into Sealing 50 respectively in the gap between boss 42 and groove 15 sidewalls.
In the compressor of said structure, the refrigerant that compresses in the compression chamber up pushes away safety check 30, and enters the hyperbaric chamber through exhaust port 13 and guide hole 41.
But common scroll compressor has following shortcoming.
Because top board 40 is fixed by welding on the compressor case, and thermal distortion usually takes place in the welding process.Thermal distortion makes top board 40 inconsistent with the center of quiet whirlpool dish, thus the boss 42 of top board with receive groove 15 relative positions and have and depart from.Therefore, may damage Sealing 50, leak in the gap between the sidewall of the reception groove 15 that the refrigerant of compression also may be by quiet whirlpool dish 10 and the boss 42 of top board 40.
Therefore, the purpose of this invention is to provide a kind of top board of architecture advances, the center of top board center and quiet whirlpool dish is in the same center line in assembling procedure.
In order to achieve the above object, the present invention includes compressor case, motor, top board, and compression assembly.
Top board comprises dividing plate and hub plate.Compression assembly comprises movable orbiting scroll and quiet whirlpool dish.
Dividing plate is fixed in the compressor case, and its inside is separated into two corresponding space.In addition, on the hub plate guide hole is arranged, can be communicated with the cavity above the top board, like this, the refrigerant of discharging from quiet whirlpool dish exhaust port can therefrom flow out.
In addition, form annular on the upper surface that coil in quiet whirlpool and receive groove.Be formed with boss on the hub plate lower surface, can insert in the reception groove of quiet whirlpool dish.Receive between groove and the boss and put Sealing.
According to the present invention, top board comprises dividing plate and two parts of hub plate, and the center that makes top board and quiet whirlpool dish is on same center line.Thereby prevent that core because of top board and quiet whirlpool dish from departing from the damage that causes Sealing and the leakage of compression refrigerant.
Can see above-mentioned purpose and advantage by the reference accompanying drawing significantly to a DETAILED DESCRIPTION OF THE PREFERRED, among the figure:
Figure 1A to 1D is the sectional view that traditional scroll compressor compression operation is shown;
Fig. 2 illustrates the longitudinal section of the top board that adopts in traditional scroll compressor and quiet whirlpool dish;
Fig. 3 is the longitudinal section that scroll compressor in accordance with a preferred embodiment of the present invention is shown; And
Fig. 4 is the enlarged view of top board among Fig. 3 and quiet whirlpool dish.
Fig. 3 and 4 illustrates the scroll compressor of one embodiment of the present invention.
As shown in the figure, comprise compression assembly 101, be used for compression refrigerant according to the scroll compressor of the preferred embodiments of the present invention; The motor 102 of drive compression assembly 101; And the compressor case 103 of interior dress compression assembly 101 and motor 102.
Compression assembly 101 has quiet whirlpool dish 110 and movable orbiting scroll 120.Quiet whirlpool dish 110 and movable orbiting scroll 120 have end plate 111 and 121 respectively, and the sidewall of end plate 111 and 121 connects spirality roll bending 112 and 122 respectively, and wherein roll bending 112 and 122 overlaps mutually, thereby defines the size of compression chamber.
For the purpose of better understanding, represent to support the bearing of eccentric shaft 102a in the drawings with label 105, label 106 refers to the suction pipe that refrigerant pass through therein, label 107 refers to discharge the exhaust port of compression refrigerants.
Under the situation that compression assembly 101 is as above assembled, dividing plate 142 welds in compressor case 103, and boss 141b injects in the dividing plate 142.Then, hub plate 141 is fixed on the dividing plate 142, the center that makes the center of hub plate 141 and quiet whirlpool dish 110 connects under the promptly coaxial situation at same center line.
According to above-mentioned the present invention, because top board 140 comprises two parts, i.e. dividing plate 142 and hub plate 141 are so no matter dividing plate 142 has or not thermal distortion with casing 103 welding the time, the center of top board 140 and quiet whirlpool dish 110 can be in the same center line.Therefore, the present invention since the center of top board 140 and quiet whirlpool dish 110 accurately aim at, thereby can prevent the breakage of Sealing 150 and the leakage of compression refrigerant.
Though the present invention specifically illustrates, and has done detailed description with reference to preferred embodiment, those skilled in the art can understand that the change on various ways and the details can be arranged under the prerequisite of essence of the present invention that does not break away from the appending claims regulation and scope.
