DETAILED DESCRIPTION

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0024] A foot pad 1 for a compressor according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] like Figure 1-Figure 2 As shown, the foot pad 1 for a compressor according to an embodiment of the present invention includes a limiting portion 100 and a support pad 200 .

[0026] The limiting portion 100 includes a relatively fixed base plate 110 and a stopper 120, which are opposed to each other and spaced apart in the longitudinal direction. A support pad 200 is used to longitudinally support the compressor body. At least a portion of the support pad 200 is disposed between the base plate 110 and the stopper 120. The support pad 200 is configured to transition between a first state and a second state. In the first state, the support pad 200 longitudinally abuts the base plate 110 and the stopper 120, respectively. In the second state, a gap is formed between the support pad 200 and the stopper 120 in the longitudinal direction.

[0027] Specifically, the gap between the support pad 200 and the stopper 120 along the longitudinal direction in the second state may be 1-3 mm.

[0028] According to the foot pad 1 for a compressor according to an embodiment of the present invention, by providing a support pad 200, the support pad 200 can respectively stop against the chassis 110 and the stopper 120 along the longitudinal direction in a first state, and can have a gap with the stopper 120 along the longitudinal direction in a second state. In this way, during the transportation of the compressor, the support pad 200 can be placed in the first state, the support pad 200 can be positioned, and the support pad 200 has a high elastic modulus, and the support pad 200 will not undergo significant deformation, thereby positioning the body of the compressor connected to the support pad 200, limiting the displacement of the compressor to a certain range, preventing the compressor from shaking or moving significantly, and avoiding damage or leakage to the compressor or piping components connected to the compressor due to excessive displacement of the compressor, thereby improving the transportation reliability and stability of the compressor.

[0029] Moreover, during the operation of the compressor, the support pad 200 can be placed in the second state, and there is a gap between the support pad 200 and the stop portion 120 in the longitudinal direction, which can solve the vibration noise problem during the operation of the compressor, facilitate reducing the operating noise of the compressor, improve the operating performance of the compressor, and improve the user's comfort.

[0030] In addition, by setting the support pad 200 to switch between the first state and the second state, compared with the method of adding a detachable gasket to the foot pad 1, the installation and disassembly process of the gasket can be omitted, the assembly process and home installation process of the compressor can be simplified, the installation convenience of the compressor can be improved, and the assembly cost and home installation cost of the compressor can be reduced.

[0031] Therefore, the foot pad 1 for the compressor according to the embodiment of the present invention has the advantages of being easy to use, convenient for transporting the compressor, and convenient for reducing the working noise of the compressor.

[0032] A foot pad 1 for a compressor according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] In some specific embodiments of the present invention, Figure 1-Figure 2 As shown, the foot pad 1 for a compressor according to an embodiment of the present invention includes a limiting portion 100 and a support pad 200 .

[0034] In some embodiments of the present invention, Figure 1 As shown, the support pad 200 has a deformable section 210 located between the stopper 120 and the chassis 110. The longitudinal dimension of the deformable section 210 when the support pad 200 is in the first state is larger than the dimension of the support pad 200 in the second state. This facilitates switching of the support pad 200 between the first and second states, ensuring the structural stability of the compressor during transportation and the operational reliability of the compressor during operation.

[0035] Specifically, if Figure 1 As shown, the deformable section 210 has a receiving cavity 211 filled with a phase change medium. This allows the deformable section 210 to change its longitudinal dimensions using the phase change medium, thereby changing the mating state between the support pad 200 and the stopper 120.

[0036] Specifically, the accommodating cavity 211 is a closed chamber that extends along the circumference of the support pad 200. There may be multiple accommodating cavities 211, which are spaced apart longitudinally. The thickness between the inner circumferential wall of the accommodating cavity 211 and the outer circumferential wall of the support pad 200 is greater than or equal to 1 mm and less than or equal to 3 mm.

[0037] It should be understood that a phase change medium is a material that is solid at room temperature and melts when the temperature reaches a predetermined temperature. Of course, the material filled in the accommodating cavity 211 can also be a non-phase change medium, that is, a material that is solid at room temperature and gradually melts or softens when the temperature reaches a certain temperature, such as paraffin or asphalt mixture.

[0038] Optionally, an anti-corrosion layer may be provided on the inner wall of the accommodating cavity 211 to isolate the support pad 200 from the phase change medium in the accommodating cavity 211. This can prevent the phase change medium from fusing or corroding with the support pad 200 material.

[0039] Alternatively, as Figure 1 As shown, the support pad 200 further comprises a compressor support position 220, the compressor support position 220 being adjacent to the stopper 120, and the deformable section 210 being adjacent to the compressor support position 220. This not only facilitates the connection between the compressor and the support pad 200, so that the compressor is supported on the support pad 200, but also facilitates the transfer of the weight of the compressor body and the heat generated during operation of the compressor to the deformable section 210, so that the deformable section 210 can switch states according to temperature changes.

[0040] Specifically, the compressor support position 220 is parallel to the compressor foot 2, so that the foot 2 can be stably supported on the support pad 200.

[0041] Furthermore, if Figure 1 As shown, the support pad 200 is further provided with a notch 230, and the deformable section 210 is located between the notch 230 and the compressor support position 220. This not only facilitates the arrangement of the deformable section 210, but also facilitates increasing the cushioning performance of the support pad 200, reducing the vibration amplitude of the compressor, and reducing the operating noise of the compressor.

[0042] Specifically, the notch 230 is an annular opening and extends along the circumference of the support pad 200 . There may be multiple notches 230 and they are spaced apart in the longitudinal direction.

[0043] In some embodiments of the present invention, the support pad 200 is configured to switch from the first state to the second state when the ambient temperature is higher than a predetermined temperature. Since the compressor is at room temperature during transportation, and the temperature of the compressor is at a higher temperature during operation, for example, the temperature of the compressor during transportation can be 20 degrees Celsius, and the operating temperature of the compressor during operation can reach 70 degrees Celsius. In this way, by setting a suitable predetermined temperature, the support pad 200 can automatically switch the working state according to the change in temperature. That is, after reaching a certain temperature, the medium in the accommodating cavity 211 melts or softens, the elastic modulus of the support pad 200 decreases, and the support pad 200 sinks slightly under the gravity of the compressor body, so that a gap is generated between the support pad 200 and the stopper 120, thereby eliminating the process of disassembling and assembling the foot pad 1, simplifying the operator's operation process, shortening the installation time of the compressor, and improving the overall performance of the compressor.

[0044] Specifically, the predetermined temperature is within a range of 65° C. to 85° C. This ensures that the support pad 200 is in the first state during transportation of the compressor, thereby improving the structural reliability of the compressor during transportation, and ensures that the support pad 200 is in the second state during operation of the compressor, thereby reducing the operating noise of the compressor.

[0045] What needs to be understood here is that after the compressor is shut down for the first time, the temperature of the compressor returns to normal temperature. The medium in the accommodating chamber 211 melts or softens under the first high-temperature operating conditions, and gradually loses the ability to resist shear deformation, resulting in radial expansion and axial compression. The side walls of the outer periphery of the accommodating chamber 211 alone cannot resist the weight of the compressor body. The medium in the accommodating chamber 211 will not rebound, and a permanent gap will be generated between the support pad 200 and the stop portion 120.

[0046] Alternatively, as Figure 1 As shown, the limiting portion 100 further includes a central column 130, which extends longitudinally. The chassis 110 and the stopper 120 are connected to the central column 130, and the support pad 200 is sleeved around the outer periphery of the central column 130. This not only facilitates the installation of the chassis 110 and the stopper 120, but also allows the central column 130 to be used to position and guide the support pad 200, thereby facilitating smooth installation of the support pad 200.

[0047] Furthermore, if Figure 1 As shown, the inner circumference of the support pad 200 is configured to be narrow at both ends and wide in the middle along the longitudinal direction. The two ends of the support pad 200 are sleeved on the central column 130, and the middle portion of the support pad 200 is spaced apart from the central column 130 to form a buffer cavity 131. This further improves the vibration damping performance of the support pad 200 and reduces the operating noise of the compressor.

[0048] Optionally, the central column 130 is a screw and the stopper 120 is a nut. One end of the central column 130 is fixedly connected to the base 110, and the nut is threadedly connected to the other end of the central column 130. This facilitates adjustment of the distance between the base 110 and the stopper 120, facilitates the matching of the support pad 200 with the limiting portion 100, and improves the structural reliability and stability of the foot pad 1.

[0049] Optionally, the support pad 200 is made of EPDM or natural rubber.

[0050] According to a specific embodiment of the present invention, the foot pad 1 includes a limiting portion 100 and a support pad 200. The limiting portion 100 includes a relatively fixed chassis 110 and a stop portion 120, and the chassis 110 and the stop portion 120 are opposite and spaced apart in the longitudinal direction. The support pad 200 is used to support the body of the compressor in the longitudinal direction. At least a portion of the support pad 200 is arranged between the chassis 110 and the stop portion 120. The support pad 200 is configured to be suitable for switching between a first state and a second state. In the first state, the support pad 200 stops against the chassis 110 and the stop portion 120 in the longitudinal direction, respectively. In the second state, the support pad 200 has a gap with the stop portion 120 in the longitudinal direction. The gap between the support pad 200 and the stop portion 120 in the longitudinal direction in the second state is 1-3 mm.

[0051] The support pad 200 is configured to switch from a first state to a second state when the ambient temperature is higher than a predetermined temperature. The predetermined temperature is in the range of 65 to 85 degrees Celsius. The support pad 200 has a deformable section 210 located between the stopper 120 and the chassis 110. The longitudinal dimension of the deformable section 210 when the support pad 200 is in the first state is larger than the dimension of the support pad 200 when the support pad 200 is in the second state. The deformable section 210 has a receiving cavity 211 therein, and the receiving cavity 211 is filled with a phase change medium. The receiving cavity 211 is a closed chamber and extends along the circumference of the support pad 200. There can be multiple receiving cavities 211, and the multiple receiving cavities 211 are spaced apart in the longitudinal direction. The inner wall of the receiving cavity 211 can be provided with an anti-corrosion layer to isolate the support pad 200 from the phase change medium in the receiving cavity 211.

[0052] The support pad 200 further comprises a compressor support portion 220, which is adjacent to the stop portion 120. The deformable section 210 is adjacent to the compressor support portion 220. The support pad 200 also comprises a notch 230, with the deformable section 210 located between the notch 230 and the compressor support portion 220. The notch 230 is an annular opening and extends along the circumference of the support pad 200. There may be multiple notches 230, spaced longitudinally.

[0053] The limiting portion 100 further includes a central column 130, which extends longitudinally. The chassis 110 and the stopper 120 are connected to the central column 130, and the support pad 200 is sleeved around the outer circumference of the central column 130. The inner circumference of the support pad 200 is configured to be narrow at both ends and wide in the middle along the longitudinal direction. The two ends of the support pad 200 are sleeved over the central column 130, and the middle portion of the support pad 200 is spaced apart from the central column 130 to form a buffer cavity 131. The central column 130 is a screw, and the stopper 120 is a nut. One end of the central column 130 is fixedly connected to the chassis 110, and the nut is threadedly connected to the other end of the central column 130.

[0054] The material of the support pad 200 is EPDM or natural rubber. The material filled in the accommodating cavity 211 is paraffin or asphalt mixture.
