The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

In conjunction with Figures 1 to 3, the shell of the compressor according to the embodiment of the present application includes a casing 10, a partition plate 30 and a cover plate 20, the partition plate 30 covers the upper opening of the casing 10, and the cover plate 20 is covered on the outer side of the partition plate 30, that is, the partition plate 30 can separate the casing 10 and the cover plate 20, and during assembly, the partition plate 30 can provide support for the casing 10 and the cover plate 20, and is convenient for positioning, and can also separate a sealed chamber in the casing. Further, the upper end of the peripheral wall of the casing 10 is stacked on the outer side of the outer peripheral surface of the partition plate 30, and the lower end of the peripheral wall of the cover plate 20 is stacked on the outer side of the outer peripheral surface of the partition plate 30, which can improve the stability of the connection, and the upper end of the casing 10 and the lower end of the cover plate 20 have a gap, which can expose the outer peripheral surface of the partition plate 30, thereby improving the stability of the connection between the partition plate 30, the cover plate 20 and the casing 10. In particular, when welding, the stability of the cover plate 20, the partition plate 30 and the casing 10 can be improved.

Among them, at least a part of the outer peripheral surface of the peripheral wall of the cover plate 20 is projected downwardly on the inner side of the outer peripheral surface of the upper end of the peripheral wall of the casing 10, so that on the outer peripheral surface of the casing, there is no interference or shielding between the peripheral wall of the cover plate 20 and the casing 10, which is conducive to the welding and assembly of the casing. In addition, in general, the cover plate 20 is covered above the casing 10, and the outer diameter of the cover plate 20 is smaller than the outer diameter of the casing 10, which is conducive to vertical welding, has little restriction on the assembly space, and is conducive to improving the compatibility of the diversified production lines of the compressor 100.

According to the shell of the compressor of the embodiment of the present application, the partition plate 30 is stacked with the cover plate 20 and the casing 10, and a gap is provided between the upper end of the casing 10 and the lower end of the cover plate 20 to expose the outer peripheral surface of the partition plate 30, thereby improving the structural stability of the shell and facilitating assembly and welding.

In conjunction with FIG. 2 and FIG. 3 , in some embodiments of the present application, the outer peripheral surface of the partition plate 30 includes a first face portion 31, a first step surface 34, and a second face portion 32, the first step surface 34 is connected between the first face portion 31 and the second face portion 32, and the downward projection of the first face portion 31 is located inside the second face portion 32, the lower end of the peripheral wall of the cover plate 20 is stacked on the outside of the first face portion 31, and the upper end of the peripheral wall of the housing 10 is stacked on the outside of the second face portion 32. In other words, the first step surface 34 is suitable for supporting the lower end of the cover plate 20, the first face portion 31 is suitable for cooperating with the peripheral wall of the cover plate 20, increasing the contact area between the cover plate 20 and the partition plate 30, and improving the cooperating stability; and the second face portion 32 is stacked with the upper end of the peripheral wall of the housing 10, which can improve the cooperating effect between the housing 10 and the partition plate 30. Specifically, a first step surface 34 is constructed between the first face portion 31 and the second face portion 32, and the first step surface 34 is used to overlap or support the lower end of the cover plate 20. The first face portion 31 and the second face portion 32 are used to be stacked with the cover plate 20 and the housing 10 to improve structural stability.

In some embodiments of the present application, the width of the first step surface 34 may be no less than the width of the lower circumferential surface of the lower end of the cover plate 20, which can improve the supporting effect and welding strength.

In conjunction with FIG. 2 , in some embodiments of the present application, the first step surface 34 is higher than the upper end of the peripheral wall of the housing 10, so that the housing 10 can avoid blocking the partition plate 30, and the assembly effect can be improved. The lower end of the peripheral wall of the cover plate 20 is supported on the first step surface 34. Specifically, the lower end of the peripheral wall of the cover plate 20 is supported on the first step surface 34, and the first step surface 34 is higher than the upper end of the peripheral wall of the housing 10. In this way, the cover plate 20, the partition plate 30 and the housing 10 are arranged in sequence around the first step surface 34 in the up-down direction, which facilitates the welding of the partition plate 30, the cover plate 20 and the housing 10 together, which is conducive to improving the structural stability.

In conjunction with FIG. 1 and FIG. 2 , in some embodiments of the present application, the peripheral wall of the housing 10 includes a barrel portion 11 and an upper end portion 13, the upper end portion 13 is connected to the upper end of the barrel portion 11, and expands outward relative to the barrel portion 11, and a second step surface 12 is formed between the inner peripheral surface of the upper end portion 13 and the inner peripheral surface of the barrel portion 11, and the partition plate 30 is supported on the second step surface 12, which can improve the stability of the matching between the housing 10 and the partition plate 30. In other words, by configuring the upper end portion 13 that expands outward relative to the barrel portion 11 at the upper end of the barrel portion 11, a step surface suitable for supporting or overlapping the partition plate 30 can be formed between the barrel portion 11 and the upper end portion 13, and the inner peripheral wall of the upper end surface can be overlapped or fitted with the outer peripheral wall or the second surface portion 32 of the partition plate 30, which is conducive to increasing the matching area and can further improve the matching stability.

With reference to FIG. 2 , in some embodiments of the present application, at least a portion of the upper end portion 13 is configured to be gradually expanded from bottom to top, so as to facilitate manufacturing and assembly.

Alternatively, the outer peripheral surface of the upper end portion 13 may extend linearly in the up-down direction, or the outer peripheral surface of the upper end portion 13 may be configured to fit with the outer peripheral wall of the partition plate 30 to improve structural stability.

In conjunction with Figure 2, in some embodiments of the present application, the outer peripheral surface of the partition plate 30 may also include a third surface 33 (or positioning surface), the third surface 33 is connected to the second surface 32, the third surface 33 is supported on the second step surface 12, and the distance between the third surface 33 and the first step surface 34 is greater than or equal to 5 mm, which can avoid the third surface 33 from being deformed by welding heat and affecting the overlap or support effect of the third surface 33 and the second step surface 12.

In some embodiments of the present application, the upper end surface of the upper end portion 13 is parallel to the second step surface 12 and is perpendicular to the axis of the casing 10, which can improve the structural stability, help improve the supporting effect of the second step surface 12 on the partition plate 30, and help improve the welding effect.

In conjunction with FIG. 2 , in some embodiments of the present application, there is a gap between the upper end of the peripheral wall of the housing 10 and the outer peripheral surface of the partition plate 30, and the upper end of the gap is open, which can facilitate assembly and welding. For example, the inner peripheral wall of the upper end portion 13 can be in an arc shape that gradually expands outward, which is conducive to improving structural stability, and there is a gap between the outer peripheral wall or the second surface portion 32 of the partition plate 30 and the inner side wall of the upper end portion 13. During assembly, the molten material during welding can enter the gap without overflowing, which is conducive to improving the welding effect and aesthetics.

In conjunction with FIG. 2 , in some embodiments of the present application, there is a gap of greater than or equal to 0.5 mm and less than or equal to 2.5 mm between the upper end of the peripheral wall of the housing 10 and the lower end of the peripheral wall of the cover plate 20 in the vertical direction. For example, the gap between the upper end of the peripheral wall of the housing 10 and the lower end of the peripheral wall of the cover plate 20 may be 0.64 mm or 0.8 mm, etc. Of course, the gap between the upper end of the peripheral wall of the housing 10 and the lower end of the peripheral wall of the cover plate 20 may also be set to a form less than 0.5 mm or greater than 2.5 mm, such as 1 mm or 3 mm, etc., according to actual conditions, and the present application is not limited thereto.

In conjunction with Figure 2, in some embodiments of the present application, the outer side of the lower end of the peripheral wall of the cover plate 20 has a chamfered structure, so that a gradually shrinking inclined surface from top to bottom is constructed on the outer peripheral surface of the lower end of the peripheral wall of the cover plate 20, which can provide space for assembly and facilitate welding operations. Especially in vertical welding, the space occupied by the production line can be reduced, which is conducive to the miniaturization of the production line.

In some embodiments of the present application, the inclination angle of the inclined surface relative to the axis of the cover plate 20 is not greater than 30°, so as to provide operating space for vertical welding and improve the compatibility of the production line.

According to the compressor 100 of the embodiment of the present application, the compressor 100 includes the aforementioned compressor shell. By applying the aforementioned shell to the compressor 100, the structural stability of the compressor 100 can be improved, and it is convenient for assembly and helps to reduce the assembly space.

The compressor 100 according to the embodiment of the present application comprises a first scroll, a second scroll and the aforementioned housing. The compressor 100 performs a gyratory motion by the rotation of the rotating shaft. The second scroll is arranged on one side of the first scroll. The partition plate 30 is located above the second scroll. The casing 10 is located outside the second scroll. The cover plate 20 is located above the partition plate 30. The casing 10 has an upper end 13 at the upper part. The upper end surface of the upper end 13 is parallel to the second step surface 12. The second step surface 12 of the casing 10 overlaps the partition plate 30 and radially constrains the partition plate 30. The lower end surface of the partition plate 30 has a positioning function (i.e., the third face 33). At the same time, the first step surface 34 of the partition plate 30 is higher than the upper end surface of the casing 10. The lower end surface of the cover plate 20 overlaps the first step surface 34 of the partition plate 30. At the same time, the outer diameter of the cover plate 20 is smaller than the outer diameter of the upper end surface of the casing 10, which is conducive to the welding and assembly of the compressor 100.

According to the compressor 100 of the present application, the upper end portion 13 is provided on the upper part of the casing 10, so that the positioning (supporting) surface of the partition plate 30 is separated from the welding part, and the assembly accuracy of the compressor 100 can be ensured. In addition, the casing of the compressor is suitable for vertical welding, which can ensure the welding quality, occupy a small space, and facilitate the miniaturization and generalization of the scroll compressor 100 production equipment.

According to the HVAC equipment of the embodiment of the present application, the HVAC equipment includes the aforementioned compressor 100. By applying the aforementioned compressor 100 to the HVAC equipment, the manufacturing cost of the HVAC equipment is reduced.

A compressor housing and a compressor 100 having the housing according to a specific embodiment of the present application will be described below with reference to the accompanying drawings.

The scroll compressor 100 utilizes an orbiting scroll with a spiral wrap and a fixed scroll with a spiral wrap, the movable scroll performs an orbiting motion relative to the fixed scroll, and when the movable scroll and the fixed scroll engage with each other, as the movable scroll performs an orbiting motion, the capacity of the pressure chamber formed between the movable scroll and the fixed scroll is reduced. Therefore, the pressure of the fluid in the pressure chamber can be increased, and the fluid is discharged from the discharge port 101 formed in the central part of the fixed scroll. A back pressure regulating chamber is formed on the fixed scroll, and the back pressure chamber having an intermediate pressure between the discharge pressure and the suction pressure can be formed on the upper end surface of the fixed scroll. That is, by forming the back pressure regulating chamber, the movable scroll and the fixed scroll can contact each other with appropriate force, refrigerant leakage can be prevented and lubrication can be increased, while the contact force can be adjusted, the friction of the contact can be reduced, but the sealing force is not reduced. Among them, the partition plate 30 of the low-pressure cavity scroll compressor 100 is located above the fixed disk, which can play a sealing role.

Combined with Figure 4, in the related art, a boss 1' is set on the outer peripheral wall of the partition plate. The width of the boss 1' is about 2.5mm. The lower end face of the boss 1' overlaps and positions with the upper end face of the lower shell 3'. The upper end face of the boss 1' overlaps the upper cover 2'. Since the outer diameter of the upper cover 2' is larger than the outer diameter of the lower shell 3', vertical welding cannot be achieved, which is not conducive to the compatibility of the production line. Most of them are handled by horizontal welding. The horizontal welding equipment occupies a large space, which is not conducive to the miniaturization of the production line. In addition, the distance of the boss 1' is short, and it is easy to be deformed by the influence of hot melting during welding, thereby reducing the stability of the structure.

The compressor 100 according to the embodiment of the present application includes a movable scroll, a fixed scroll and a casing. The movable scroll has a base plate and a scroll tooth connected to the base plate. The fixed scroll and the movable scroll together form a suction chamber, an intermediate pressure chamber and a discharge chamber.

Specifically, the housing includes a casing 10, a cover plate 20 and a partition plate 30. The casing 10 includes a cylinder 11 and an upper end 13 and expands outward relative to the cylinder 11. The upper end 13 is connected to the upper end of the cylinder 11, and a second step surface 12 is constructed between the inner circumference of the upper end 13 and the inner circumference of the cylinder 11. The partition plate 30 includes a first face 31, a first step surface 34, a second face 32 and a third face 33 connected in sequence. The third face 33 is supported on the second step surface 12, and the second face 32 is opposite to the inner circumference of the upper end 13. The lower end of the cover plate 20 is supported on the first step surface 34 and the inner circumference of the lower end of the cover plate 20 is opposite to the first face 31. The outer side of the lower end of the peripheral wall of the cover plate 20 has an inclined surface inclined 30° from top to bottom.

It can be seen that in the related art, the welding of the three parts of the low-pressure chamber partition plate, the upper cover 2' and the lower shell 3' can only be achieved through horizontal welding. The shell of the compressor of the embodiment of the present application is formed by setting an upper end 13 at the upper end of the casing 10, forming a step area through the upper end 13 and the barrel 11, and utilizing the welding angle arrangement and welding quality assurance. At the same time, the distance between the positioning surface of the partition plate 30 (i.e., the third surface 33) and the support surface of the cover plate 20 is increased, ensuring that the welding process does not affect the flatness and parallelism of the partition plate 30, achieving high-precision assembly of the compressor 100, and solving the problem that vertical welding cannot be applied.

In addition, in the present application, by setting the upper end portion 13 on the casing 10, the influence of the welding of the partition plate 30 on the positioning surface can be reduced, which is convenient for ensuring the accuracy of the compressor 100. At the same time, through the special inclination angle of the cover plate 20, the increased distance between the partition plate 30 and the superposition of the three parts of the upper end portion 13 of the casing 10, the function of vertical welding is realized, which will not bring additional processing costs and assembly costs, and is beneficial to the compatibility of the diversified production lines of the compressor 100.
