The housing assembly provided by the embodiment of the utility model includes a housing 1 and a vibration-damping foot. The vibration-damping foot includes a mounting foot and a vibration-damping washer. There are at least two kinds of vibration-damping feet. There is a height difference in the axial direction of the body 1; the ends of the vibration-damping washers of all the vibration-damping feet away from the mounting feet are located on the same plane. The height of the vibration-damping washers of any two kinds of vibration-damping feet is different. One end of the vibration-damping washer is far away from the end of the mounting foot. This end needs to be in contact with the working surface (inner wall of the air conditioner shell), and the other end of the vibration-damping washer is connected to the mounting foot. There is a height difference in the axial direction, therefore, the heights of the vibration-damping washers of any two kinds of vibration-damping supports are different.

The housing assembly provided by the embodiment of the utility model can damp the vibration of the housing 1 by setting at least two kinds of vibration-damping feet, so that the housing 1 has a plurality of vibration-damping washers with different heights for vibration reduction, effectively avoiding the same vibration-damping feet The occurrence of synchronous vibration effectively improves the vibration damping effect, reduces the vibration to the compressor exhaust port, and improves the reliability of the compressor.

In order to reduce the types of components and reduce production costs, there are two kinds of damping feet in this embodiment, which are the first damping feet and the second damping feet; The height in the axial direction is lower than the height in the axial direction of the casing 1 of the second mounting leg 4 of the second shock absorbing leg. That is, the height of the first vibration-damping washer 3 of the first vibration-damping support foot is lower than the height of the second vibration-damping washer 5 of the second vibration-damping support foot.

As shown in FIG. 3 , in this embodiment, the height from the contact surface B of the first mounting foot 2 of the first vibration-damping foot to the first vibration-damping washer 3 of the first vibration-damping foot to the bottom surface of the housing 1 is h1, The height from the contact surface A of the second installation foot 4 of the second damping foot to the second shock washer 5 of the second shock absorption foot to the bottom surface of the housing 1 is h2, and the suction port of the housing 1 reaches the housing 1 The height of the bottom surface is h3; h1<h2<h3. Through the above setting, the suction port of the housing 1 is located between the top surface of the first damping washer 3 of the first damping leg (the contact surface with the mounting leg) and the second damping washer 5 of the second damping leg. Between the top surface (the contact surface with the mounting leg), the position is stabilized, and the vibration of the suction port of the casing 1 is effectively reduced.

Wherein, the height from the suction port of the casing 1 to the bottom surface of the casing 1 is the height from the center of the suction port of the casing 1 to the bottom surface of the casing 1 .
