Description

Technical Field

[0001] The present invention relates to the technical field of compressors, in particular to an elastic foot of a compressor and a compressor comprising the elastic foot. Background Art

[0002] The compressor usually includes a motor that generates driving force and a pump body connected to the motor for compressing the refrigerant, and the motor and the pump body are accommodated in the housing of the compressor. When the compressor is running, the rotational force of the motor drives the pump body to compress the refrigerant. During this process, vibration and noise are generated. Usually, the compressor is set on the foot, which can reduce vibration and noise while installing and fixing the compressor.

[0003] There are two main types of existing compressor feet. One is a foot with a small hole on the upper part. This foot is easy to contact with the positioning screw, causing the compressor vibration to be transmitted to the compressor chassis to generate vibration noise; the other is a foot with a large hole. This foot has poor positioning for the compressor, especially in the current small compressors. Due to the light gravity, the compressor will tilt and twist during the pipeline welding and pulling process. The large hole foot is not positioned, resulting in poor system status.

[0031] The present invention provides a compressor elastic foot and a compressor including the same, wherein the elastic foot is cylindrical and is provided with a through hole along its axial direction; the inner wall of the through hole is provided with a lower boss and an upper boss, and the lower boss and the upper boss are configured to support the compressor positioning bolt; the outer peripheral surface of the elastic foot is provided with a limiting groove, and the limiting groove is configured to be clamped with the compressor base; the upper boss is below the limiting groove. Preferably, the vertical distance between the highest point of the upper boss close to the side of the positioning bolt and the limiting groove in the axial direction of the elastic foot is H, and satisfies: H ≥ 1mm. Furthermore, H is less than 1 / 2 of the height of the through hole to avoid affecting the positioning and causing the compressor to twist. The compressor elastic foot through hole of the present invention is provided with a lower boss and an upper boss, and the outer peripheral surface is provided with a limiting groove, so as to realize positioning with the compressor base and the positioning bolt, and reduce the tilt and deflection angle of the compressor; at the same time, since the upper boss and the limiting groove are not arranged on the same plane, the vibration transmitted by the compressor base and the positioning bolt through the elastic foot is reduced, and when the compressor is tilted or deflected, the elastic foot and the positioning bolt are elastically contacted through the upper boss, thereby reducing the noise caused by the vibration transmission of the compressor base, and realizing vibration reduction and noise reduction.

[0032] The following further describes the elastic foot of the compressor and the compressor including the same according to the present invention in conjunction with the accompanying drawings and specific embodiments. It should be understood that the various specific embodiments are not intended to limit the protection scope of the present invention.

[0033] Figure 1 and Figure 2 They are respectively a schematic diagram and a cross-sectional view of the structure of the elastic foot of the compressor of the first embodiment of the present invention. Specifically, the elastic foot of the compressor 1 is cylindrical, and a through hole 11 is provided along its axial direction; the inner wall of the through hole 11 is provided with a lower boss 111 and an upper boss 112. When the elastic foot of the compressor 1 is used in the compressor, the lower boss 111 and the upper boss 111 are configured to support the positioning bolt of the compressor; the outer peripheral surface of the elastic foot 1 is provided with a limiting groove 13. When the elastic foot of the compressor 1 is used in the compressor, the limiting groove 13 is configured to be clamped with the compressor base; the upper boss 112 is below the limiting groove 13. The vertical distance between the upper boss 11 and the limiting groove 13 in the axial direction of the elastic foot 1 is H, and satisfies: H≥1mm. In the first embodiment, the elastic foot of the compressor 1 is an integral part, which can be a plastic part or a rubber part, and the plastic part can be a high-damping plastic part. The rubber integral part helps to maintain the elasticity and service life of the elastic foot.

[0034] When the elastic foot 1 is combined with the positioning bolt of the compressor, the upper boss 112 is the contact point between the elastic foot 1 and the screw of the positioning bolt, and the limiting groove 13 is the contact point between the elastic foot 1 and the compressor base. When the two are in the same plane, the probability of the vibration of the compressor base being transmitted to the positioning bolt by the limiting groove 13 and the upper boss 112 becomes greater, thereby causing noise. In the present invention, the upper boss and the limiting groove are not arranged on the same plane, or in other words, below the limiting groove, and the vertical distance H between the two can be determined according to the structure of the compressor used and the compressor base, thereby minimizing the vibration transmitted by the compressor base and the positioning bolt through the elastic foot, reducing the noise caused by the vibration transmission of the compressor base, and achieving vibration reduction and noise reduction.

[0035] Some structural features of the elastic foot of the compressor are further explained below in conjunction with the structure when it is used in the compressor. Figure 3 and Figure 4 The cross-sectional view of the elastic foot of the first embodiment of the present invention when used in a compressor, wherein the compressor further comprises a compressor base 3 and a positioning bolt, the compressor base 3 is engaged with the limiting groove 13 of the elastic foot 1 of the compressor, in practice, the portion above the limiting groove 13 of the elastic foot 1 of the compressor passes through the through hole on the compressor base 3, and the inner wall of the through hole on the compressor base 3 is engaged with the limiting groove 13. The positioning bolt comprises a cap seat 21 and a screw 22, and the screw 22 is arranged in the through hole 11 from bottom to top; in the first embodiment, the cross-section of the upper boss 112 is a plane, that is, the inner periphery of the upper boss 112 is a plane, and at this time, the inner periphery plane of the upper boss 112 is parallel to the screw 22 of the positioning bolt. The distance between the plane of the upper boss 112 and the outer periphery of the bolt 22 is defined as L, and satisfies: 0.5mm≤L≤1.5mm, such as L is 1.0mm, etc. The test results show that when L is within the above range, the influence of the tilt and torsion of the compressor will be reduced. Furthermore, the thickness of the upper boss 112 along the axial direction of the elastic foot 1 is T. In this embodiment, T is the thickness of the plane in the axial direction, satisfying: T≥2mm.

[0036] Similarly, in order to reduce the vibration transmitted between the compressor base and the positioning bolt through the elastic foot, the inner diameter of the upper part of the through hole 11 of the elastic foot 1, that is, the part above the upper boss 112 is D, and the inner diameter of the upper boss 112 is d, which is 2mm≤Dd≤3mm. At this time, the elastic foot 1 does not directly contact the screw and the compressor base at the same time along the axial direction, thus reducing the direct transmission of vibration. Further, if Figure 2As shown, the through hole between the upper convex platform 112 and the lower convex platform 111 is the second through hole, and the maximum inner diameter of the through hole above the upper convex platform is smaller than the maximum inner diameter of the second through hole. This structure further reduces the vibration transmitted from the compressor to the chassis through the elastic feet. At the same time, the feet have better elasticity.

[0037] In the first embodiment, there is a certain gap between the lower convex platform 111 and the bolt 22, and the distance or gap between the two is l. Optionally, l < L. Preferably, l satisfies: 0 ≤ l ≤ 0.25 mm. In addition, in order to eliminate a certain inclination of the compressor base, the outer peripheral surface of the elastic foot 1 is wavy or serrated along its axial direction, as Figure 2 shown. This wavy or serrated structure increases the elasticity of the elastic foot in the axial direction and reduces the vibration transmitted from the compressor to the chassis through the elastic foot.

[0038] Figure 5 This is a sectional view of the elastic foot of the compressor according to the second embodiment of the present invention. Among them, the cross section of the upper convex platform 112b of the elastic foot 1b of the compressor is arc-shaped. At this time, the distance between the top of the arc-shaped upper convex platform 112b and the outer peripheral surface of the bolt 22 is defined as L, and the distance L also needs to be between 0.5 mm and 1.5 mm.

It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above descriptions.
