Description

Technical Field

[0001] The present invention relates to the field of compressors, and specifically to a supporting foot pad, a compressor assembly, and an electrical appliance. Background Art

[0002] Compressors generally adopt flexible supports, that is, the supporting foot pads of the compressors are elastic foot pads. If the stiffness of the supporting foot pads is too large, the operating vibration of the compressor will be transmitted to other components of the electrical appliance to a large extent through the supporting foot pads, affecting the normal performance of other components on the electrical appliance product and the performance and service life of the electrical appliance product; if the stiffness of the supporting foot pads is too small, it will cause obvious vibration of the entire compressor, resulting in an unstable installation state of the compressor and affecting the normal operation of the compressor.

[0003] The Chinese utility model patent with the publication number CN207989260U shows that the vibration of the compressor has a main vibration direction, and the vibration intensity in this main vibration direction is significantly greater than that in other directions.

[0004] However, the existing supporting foot pads have an equal ability to limit the vibration of the compressor in each diameter direction. In order to balance the requirements for the stiffness of the supporting foot pads in the main vibration direction and the non-main vibration direction of the compressor, on the one hand, this results in the stiffness of the supporting foot pads being insufficient to effectively limit the vibration in the main vibration direction of the compressor, resulting in a relatively large overall amplitude of the compressor in the main vibration direction during operation, which has an adverse effect on the normal operation of the compressor. On the other hand, it causes the supporting foot pads to overly limit the vibration of the compressor in other directions, resulting in the excessive transmission of the vibration of the compressor in other directions to other components of the electrical appliance product through the supporting foot pads, affecting the normal performance of other components and the performance and service life of the electrical appliance product. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a supporting foot pad with different shock-absorbing capabilities in different directions.

[0006] To achieve the above purpose, the supporting foot pad provided by the present invention includes an inner skeleton, an outer skeleton, a first elastic support body, and a second elastic support body. The outer skeleton is a cylinder, and the inner skeleton is arranged inside the cylinder of the outer skeleton; the first elastic support body is squeezed between the inner skeleton and the inner wall of the outer skeleton along a first horizontal direction, and the second elastic support body is squeezed between the inner skeleton and the inner wall of the outer skeleton along a second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction, and the stiffness of the first elastic support body is greater than that of the second elastic support body.

[0007] As can be seen from the above, through the structural design of the supporting foot pad, the present invention enables the supporting foot pad to have a relatively strong ability to limit the vibration in the first horizontal direction and a relatively weak ability to limit the vibration in other directions. The supporting foot pad of the present invention can match the vibration characteristics of the compressor, and the supporting foot pad of the present invention is suitable for fixedly shock-absorbing and supporting the compressor.

[0008] A preferred solution is that the inner skeleton is a cylinder.

[0009] As can be seen from the above, the setting of the cylinder facilitates the penetration of bolts, and facilitates the fixed connection of the inner skeleton and the compressor through bolts.

[0010] Another preferred solution is that both the first elastic support body and the second elastic support body are rubber bodies. The first elastic support body and the second elastic support body are both vulcanized and fixed on the inner skeleton, and the first elastic support body and the second elastic support body are both vulcanized and fixed on the inner wall of the outer skeleton.

[0011] Yet another preferred solution is that the inner skeleton is a cylindrical body, and / or the outer skeleton is a cylindrical body.

[0012] The second object of the present invention is to provide a compressor assembly that is conducive to restricting the vibration degree of the compressor in each diameter direction to an appropriate range.

[0013] To achieve the above object, the compressor assembly provided by the present invention includes a compressor and at least three support feet. The compressor is supported on the support feet; the support feet include a first elastic support body distributed along a first horizontal direction and a second elastic support body distributed along a second horizontal direction. The stiffness of the first elastic support body is greater than that of the second elastic support body; the main vibration direction of the compressor is along the first horizontal direction.

[0014] As can be seen from the above, through the structural design of the compressor assembly of the present invention, since the vibration intensity of the compressor in the main vibration direction is the strongest, and the support feet provided by the present invention have the strongest vibration limiting ability in the main vibration direction of the compressor, this is conducive to matching the vibration limiting ability of the support feet to the vibration of the compressor in a specific direction with the vibration intensity of the compressor in this specific direction. This is conducive to restricting the vibration intensity of the compressor in each diameter direction to an appropriate range, avoiding excessive vibration of the compressor in the main vibration direction, avoiding affecting the normal operation of the compressor, and also avoiding excessive transmission of the vibration of the compressor in the non-main vibration direction to the external components of the compressor through the support feet. This is not only conducive to ensuring excellent performance of the compressor, but also conducive to avoiding excessive influence on the normal operation of the external components of the compressor.

[0015] A preferred solution is that the support feet further include an inner skeleton and an outer skeleton. The first elastic support body is extruded between the inner skeleton and the inner wall of the outer skeleton along the first horizontal direction, and the second elastic support body is extruded between the inner skeleton and the inner wall of the outer skeleton along the second horizontal direction; the inner skeleton is fixedly connected to the compressor, or the outer skeleton is fixedly connected to the compressor.

[0016] A further solution is that the inner skeleton is a cylinder, and the compressor's feet are provided with mounting holes. The feet are fixedly connected to the corresponding supporting foot pads by bolts, and the bolts penetrate through the corresponding mounting holes and the cavity of the corresponding rigid inner cylinder.

[0017] A further solution is that the inner skeleton is a cylindrical body, and / or the outer skeleton is a cylindrical body.

[0018] The third object of the present invention is to provide an electrical appliance that is conducive to restricting the vibration degree of the compressor in each diameter direction to an appropriate range.

[0019] To achieve the above object, the electrical appliance provided by the present invention includes a mounting base and the aforementioned compressor assembly, and the supporting foot pads are fixedly supported on the mounting base.

[0020] As can be seen from the above, due to the adoption of the aforementioned compressor assembly in the electrical appliance of the present invention, it is beneficial to ensure excellent performance of the compressor, and at the same time, it is beneficial to avoid affecting the normal operation of other components of the electrical appliance product, which is conducive to improving the overall performance and service life of the electrical appliance product.

[0021] A preferred solution is that the mounting base is provided with a mounting groove, and the supporting foot pad is embedded in the mounting groove.

[0022] As can be seen from the above, this is conducive to the stable and reliable fixed connection between the mounting base and the supporting foot pad. Description of the Drawings

[0029] Embodiment of the supporting foot pad:

[0030] Please refer toFigure 3 and Figure 4 , the support foot pad 2 includes an inner skeleton 21, an outer skeleton 22 and four elastic support bodies 23. Two of the four elastic support bodies 23 are first elastic support bodies 231, and the other two are second elastic support bodies 232. Both the inner skeleton 21 and the outer skeleton 22 are metal cylinders. The inner skeleton 21 is located inside the cylinder of the outer skeleton 22. The axis of the cylinder of the inner skeleton 21 coincides with the axis of the cylinder of the outer skeleton 22 and both are along the vertical direction. Both the first elastic support body 231 and the second elastic support body 232 are rubber bodies. The stiffness of the first elastic support body 231 is greater than that of the second elastic support body 232. All four elastic support bodies 23 are extruded between the outer wall of the inner skeleton 21 and the inner wall of the outer skeleton 22. The four elastic support bodies 23 are distributed circumferentially along the inner skeleton 21. The two first elastic support bodies 231 are respectively located on both sides of the inner skeleton 21 along the X-axis direction, and the two second elastic support bodies 232 are respectively located on both sides of the inner skeleton 21 along the Y-axis direction. Both the first elastic support body 231 and the second elastic support body 232 are fixed to the inner skeleton 21 by vulcanization, and both the first elastic support body 231 and the second elastic support body 232 are fixed to the outer skeleton 22 by vulcanization.

[0031] Optionally, the inner skeleton 21 and the outer skeleton 22 can also be made of rigid non-metallic materials.

[0032] Optionally, the two first elastic support bodies 21 can also be connected to each other as a whole. Similarly, the two second elastic support bodies 22 can also be connected to each other as a whole.

[0033] Preferably, please refer to Figure 4 , in this embodiment, both the inner skeleton 21 and the outer skeleton 22 are cylinders, and their cross-sectional shapes are circular; optionally, the cross-sectional shapes of the inner skeleton 21 and the outer skeleton 22 can also be regular polygons, such as squares, regular pentagons, etc. Of course, it is preferred that the inner contour of the cross-section of the inner skeleton 21 is still circular, which is beneficial for the inner skeleton 21 to cooperate with the bolt 24.

[0034] Compressor assembly, Embodiment 1:

[0035] Please refer to Figures 1 to 4 , the compressor assembly of this embodiment includes a compressor 1 and three of the aforementioned support foot pads 2. There are three feet 11 distributed circumferentially on the compressor 1. The three feet 11 correspond to the three support foot pads 2 one by one, and each foot 11 is respectively fixedly supported on the corresponding support foot pad 2.

[0036] Specifically, please refer to Figure 3, the mounting feet 11 are provided with mounting holes. The bolts 24 sequentially penetrate through the inner skeleton 21 barrel cavities and the mounting holes corresponding to each other in the vertical direction and are then threadedly connected to the nuts 25, thereby realizing the fixation of the mounting feet 11 and the supporting foot pads 2. Optionally, threads can also be provided on the inner wall of the inner skeleton 21. The bolts first penetrate through the mounting holes and then are threadedly connected to the inner skeleton 21.

[0037] When the compressor 1 operates, it has a main vibration direction. The main vibration direction of the compressor 1 can be obtained through detection and will not be elaborated here. In this embodiment, the X-axis direction is the same as the main vibration direction of the compressor 1.

[0038] Since the stiffness of the first elastic support 231 is greater than that of the second elastic support 232, the supporting foot pad 2 has a stronger ability to restrict the vibration of the compressor 1 in the X-axis direction and a weaker ability to restrict the vibration of the compressor 1 in the Y-axis direction. In this way, the supporting foot pad 2 has a greater restrictive effect on the vibration of the compressor 1 in the X-axis direction and a smaller restrictive effect on the vibration of the compressor 1 in the Y-axis direction. That is to say, the supporting foot pad 2 has a greater restrictive effect on the vibration of the compressor 1 in the main vibration direction. This is beneficial to restricting the vibration degree of the compressor 1 in each diameter direction to an appropriate range through the supporting foot pad 2, avoiding excessive overall vibration intensity of the compressor 1, avoiding affecting the normal operation of the compressor 1, and also avoiding excessive transmission of the vibration of the compressor 1 in the non-main vibration direction to the external components of the compressor 1 through the supporting foot pad 2. This is beneficial to ensuring excellent performance of the compressor 1 and also beneficial to avoiding excessive influence on the normal operation of the external components of the compressor 1, and is beneficial to improving the performance and service life of the external components of the compressor 1.

[0039] Optionally, in this embodiment, the number of the supporting foot pads 2 can also be four or five. The first elastic supports 231 in each supporting foot pad 2 are all distributed along the X-axis direction, and the second elastic supports 232 in each supporting foot pad 2 are all distributed along the Y-axis direction.

The air conditioner can be an integrated air conditioner or a split air conditioner. The electrical appliance in this embodiment includes the aforementioned compressor assembly. Taking the split air conditioner as an example, the compressor assembly is arranged in the outdoor unit of the split air conditioner. The split air conditioner has a mounting base 3, and all three supporting foot pads 2 are fixedly supported on the mounting base 3. The mounting base 3 can be the bottom case of the air conditioner outdoor unit or a structure for mounting the compressor 1 fixed on the air conditioner outdoor unit housing.

[0042] Due to the adoption of the aforementioned compressor assembly, the appliance of this embodiment is conducive to restricting the vibration degree of the compressor 1 in each diameter direction to a proper range through the supporting foot pads 2, avoiding excessive overall vibration intensity of the compressor 1, preventing the normal operation of the compressor 1 from being affected, and also preventing the vibration of the compressor 1 in the non-main vibration direction from being excessively transmitted to other components of the electrical appliance product through the supporting foot pads 2. This is beneficial to ensuring excellent performance of the compressor 1 and avoiding excessive influence on the normal operation of other components of the electrical appliance product, and is conducive to improving the overall operation performance and lifespan of the electrical appliance product.

[0043] Preferably, please refer to Figure 3 , three installation grooves are provided on the installation base 3, and the outer skeletons 22 of the three supporting foot pads 2 are respectively and correspondingly embedded in the three installation grooves. The supporting foot pads 2 are fixed to the installation base 3. For example, the outer skeleton 22 can be welded to the side wall 31 of the installation groove.

[0044] Optionally, the inner skeleton 21 can also be fixedly connected to the installation base 3, and the outer skeleton 22 can be fixedly connected to the machine foot 11.

The third elastic supporting body 26 includes a first main body portion 261, a first connecting portion 262, and a second main body portion 263 distributed along the X-axis direction. The first connecting portion 262 is connected between the first main body portion 261 and the third main body portion 263. When the compressor assembly is applied to the electrical appliance, along the X-axis direction, the outer side wall of the first main body portion 261 abuts against the side wall 31 of the installation groove, the inner side wall of the first main body portion 261 abuts against the convex ring 111, the inner side wall of the second main body portion 263 abuts against the convex ring 111, and the outer side wall of the second main body portion 263 abuts against the side wall 31 of the installation groove.

[0047] Similarly, the fourth elastic supporting body 27 includes a third main body portion 271, a second connecting portion 272, and a fourth main body portion 273 distributed along the Y-axis direction. When the compressor assembly is applied to the electrical appliance, along the Y-axis direction, the outer side wall of the third main body portion 271 abuts against the side wall 31 of the installation groove, the inner side wall of the third main body portion 271 abuts against the convex ring 111, the inner side wall of the fourth main body portion 273 abuts against the convex ring 111, and the outer side wall of the fourth main body portion 273 abuts against the side wall 31 of the installation groove.
