The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A compressor housing 10 according to an embodiment of the present invention is described below with reference to fig. 1-4.

As shown in fig. 1-4, a compressor housing 10 according to an embodiment of the present invention. The compressor housing 10 includes an upper housing 11 and a lower housing 12.

Specifically, as shown in fig. 1, in the height direction of the compressor, the upper housing 11 includes a first tapered section 111 and a first connection section 112 connected to the first tapered section 111. Therefore, by forming the first tapered section 111 on the upper shell 11, the stability of the upper shell 11 can be improved by using the characteristic of high stability of the tapered structure, so that the vibration amplitude of the upper shell 11 is reduced when the compressor is operated, and the vibration noise of the compressor is further reduced.

As shown in fig. 1, in the height direction of the compressor, the lower shell 12 includes a second connection section 121 and a second taper section 122 connected to the second connection section 121. Therefore, the second conical section 122 is constructed on the lower shell 12, so that the stability of the lower shell 12 can be improved by utilizing the characteristic of high stability of the conical structure, and the vibration amplitude of the lower shell 12 is reduced when the compressor runs, thereby reducing the vibration noise of the compressor.

As shown in fig. 1, the first connection segment 112 may be plug-connected with the second connection segment 121 such that the upper housing 11 and the lower housing 12 define a mounting cavity. Therefore, by constructing the first connection section 112 on the upper shell 11 and constructing the second connection section 121 adapted to be plugged with the first connection section 112 on the lower shell 12, the upper shell 11 and the lower shell 12 can be connected to construct the compressor shell 10 by using the plugging fit of the first connection section 112 and the second connection section 121, so that the connection manner can be simplified and the assembly efficiency and the tightness of the compressor shell 10 can be improved.

For example, as shown in fig. 1, the upper housing 11 is located above the lower housing 12, the first connecting section 112 is located below the first tapered section 111, the second connecting section 121 is located above the second tapered section 122, and the first connecting section 112 can be plugged into the second connecting section 121 to connect the upper housing 11 and the lower housing 12.

According to the compressor housing 10 of the embodiment of the present invention, the first tapered section 111 is formed on the upper housing 11, and the second tapered section 122 is formed on the lower housing 12, so that the stability of the upper housing 11 and the lower housing 12 can be improved by using the characteristic of high stability of the tapered structure, and thus, when the compressor is operated, the vibration amplitude of the upper housing 11 and the lower housing 12 is reduced, and the vibration noise of the compressor is further reduced.

As shown in fig. 2 and 3, according to some embodiments of the present invention, at least one of the first connection section 112 and the second connection section 121 has a cylindrical shape. It is understood that the first connection section 112 may be cylindrical; the second connection section 121 may also be cylindrical; alternatively, as shown in fig. 2 and 3, each of the first connection section 112 and the second connection section 121 may have a cylindrical shape. It should be noted that the cylindrical structure has the advantages of easy molding, good sealing effect and high stability. Therefore, at least one of the first connection section 112 and the second connection section 121 is made to be cylindrical, so that the production process of the first connection section 112 or the second connection section 121 can be simplified, the cost can be saved, the tightness of the fit connection between the first connection section 112 and the second connection section 121 can be improved, and the reliability of the compressor housing 10 can be improved.

For example, as shown in fig. 1, when the cylindrical first connecting section 112 is inserted into and mated with the cylindrical second connecting section 121, the outer circumferential wall of the first connecting section 112 may be attached to the inner circumferential wall of the second connecting section 121. Therefore, the connection part between the first connection section 112 and the second connection section 121 can be hermetically protected in the circumferential direction of the second connection section 121 by the insertion fit of the first connection section 112 and the second connection section 121.

According to some embodiments of the present invention, the first connection segment 112 and the second connection segment 121 may be welded. It should be noted that welding has the advantages of good sealing performance and high connection strength. Accordingly, by welding the first connection segment 112 and the second connection segment 121, the fastening property and stability of the connection between the upper casing 11 and the lower casing 12 can be improved, and the sealing property at the connection between the upper casing 11 and the lower casing 12 can be improved, thereby improving the reliability of the compressor casing 10.

As shown in fig. 1 and 3, according to some embodiments of the present invention, the cross-sectional area of the first tapered section 111 gradually increases in a top-to-bottom direction. As shown in fig. 1, the first connection section 112 is connected to a lower end of the first tapered section 111, a lower end of the first tapered section 111 may be a connection end, the connection of the first connection section 112 and the second connection section 121 may serve as a supporting and fixing structure of the first tapered section 111, and an upper end of the first tapered section 111 may be an opposite free end. From this, through making the cross-sectional area of first toper section 111 from last to increasing gradually, can make the cross-sectional area of first toper section 111 reduce gradually from the link to the free end to can reduce the volume and the weight of free end, and then can reduce the vibration range of free end, with the stability that improves first toper section 111.

Further, as shown in fig. 1, the first tapered section 111 may be inclined toward the inside of the compressor housing 10 in a direction from below to above, and the angle α of the first tapered section 111 to the vertical plane is between 0 ° and 45 °. Accordingly, by setting the angle α of inclination of the first tapered section 111 toward the inside of the compressor housing 10 to a reasonable value, the stability of the first tapered section 111 can be improved, thereby reducing the vibration noise of the upper housing 11, and the upper housing 11 can have a sufficient receiving space for facilitating the installation of the working elements in the compressor housing 10.

As shown in FIG. 2, according to some embodiments of the invention, the second tapered section 122 gradually decreases in cross-sectional area in a top-to-bottom direction. As shown in fig. 1 and 2, the second connecting section 121 is connected to the upper end of the second conical section 122, the upper end portion of the second conical section 122 may be a connecting end, the connection of the first connecting section 112 and the second connecting section 121 may serve as a supporting and fixing structure of the second conical section 122, and the lower end portion of the second conical section 122 may be an opposite free end. Therefore, the cross-sectional area of the first tapered section 111 is gradually reduced from top to bottom, so that the cross-sectional area of the second tapered section 122 is gradually reduced from the connecting end to the free end, the volume and the weight of the free end can be reduced, the vibration amplitude of the free end can be reduced, and the stability of the second tapered section 122 is improved.

Further, as shown in fig. 1, the second conical section 122 may be inclined toward the inside of the compressor housing 10 in a direction from top to bottom, and the angle β of the second conical section 122 to the vertical plane is between 0 ° and 45 °. Therefore, by setting the internal inclination angle α of the second conical section 122 toward the compressor housing 10 to a reasonable value, the stability of the second conical section 122 can be improved, thereby reducing the vibration noise of the lower housing 12, and the lower housing 12 can have a sufficient receiving space for facilitating the installation of the working elements in the compressor housing 10.

In addition, the inclination angle α and the inclination angle β may be used to detect whether the compressor housing 10 is acceptable. For example, when the inclination angle α of the first tapered section 111 does not correspond to the preset angle, it is considered that the compressor housing 10 may have a problem of dimensional failure.

As shown in FIG. 2, according to some embodiments of the present invention, the maximum value of the cross-sectional area of the second tapered section 122 is smaller than the cross-sectional area of the second connecting section 121. Therefore, the difference in cross-sectional area between the second tapered section 122 and the second connecting section 121 can be utilized to form the receiving groove 1211 at the joint between the second tapered section 122 and the second connecting section 121, and the receiving groove 1211 can be used to receive the first connecting section 112, so that the fitting degree of the first connecting section 112 and the second connecting section 121 can be improved.

It should be noted that, as shown in fig. 4, the bottom wall of the receiving groove 1211 may abut against the lower surface of the first connecting section 112, so that when the upper housing 11 is assembled with the lower housing 12, the bottom wall of the receiving groove 1211 may limit the installation of the upper housing 11 in the vertical direction, thereby facilitating the alignment of the butt joint position between the upper housing 11 and the lower housing 12, and further improving the assembly efficiency between the upper housing 11 and the lower housing 12.

According to some embodiments of the invention, at least one of the upper housing 11 and the lower housing 12 is a stamped part. It is understood that the upper housing 11 may be a stamped piece; the lower housing 12 may be a stamped part; alternatively, both the upper case 11 and the lower case 12 may be stamped parts. It should be noted that the stamping part has the advantages of high dimensional accuracy and high structural strength. Thus, by using a stamping as the upper shell 11 or the lower shell 12, it is possible to improve both the dimensional accuracy of the upper shell 11 or the lower shell 12, thereby improving the reliability of the assembly of the compressor shell 10, and the structural strength of the upper shell 11 or the lower shell 12, thereby improving the deformation resistance of the compressor shell 10.

According to some embodiments of the present invention, the outer surface of at least one of the upper case 11 and the lower case 12 includes a connection plane. It will be appreciated that the outer surface of the upper housing 11 may include a connection plane; the outer surface of the lower shell 12 may also include a connection plane; alternatively, both the outer surface of the upper case 11 and the outer surface of the lower case 12 may include the connection plane. Thus, by making the outer surface of at least one of the upper and lower cases 11 and 12 include the joining plane, the joining plane can be used as a mounting platform for parts provided on the outer surface of the compressor case 10. It can be appreciated that the connection plane has a better installation convenience than the curved surface, so that the utility of the compressor housing 10 can be improved.

For example, the working elements inside the compressor housing 10 need to be externally connected with a power source, and accordingly, an electrical connection terminal or an electrical connection channel needs to be constructed at a corresponding position of the compressor housing 10. For example, when the electrical connection terminals or the electrical connection channels need to be disposed on the upper housing 11, the outer surface of the upper housing 11 needs to have a connection plane, so as to facilitate the layout of the electrical connection terminals or the electrical connection channels.

According to some embodiments of the invention, the outer wall surface of at least one of the first tapered section 111 and the second tapered section 122 may comprise a connection plane. Therefore, by forming the connection plane on the first tapered section 111 or the second tapered section 122, a mounting platform can be provided for the components arranged on the outer surface of the compressor housing 10, and at the same time, the probability of interference between the components and the first connection end or the second connection end is reduced, so that the layout of the outer surface of the compressor housing 10 can be optimized.

The compressor according to the embodiment of the present invention includes the compressor housing 10 described above.

According to the compressor of the embodiment of the present invention, the first tapered section 111 is formed on the upper shell 11, and the second tapered section 122 is formed on the lower shell 12, so that the stability of the upper shell 11 and the lower shell 12 can be improved by using the characteristic of high stability of the tapered structure, and thus, when the compressor is in operation, the vibration amplitude of the upper shell 11 and the lower shell 12 is reduced, and further, the vibration noise of the compressor is reduced.
