Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and particularly relates to a compressor and a refrigerator. Background Art

[0002] When a refrigerator is working, it often generates noise, which mainly comes from the vibration noise generated during the operation of the compressor.

[0003] In the related art, usually, vibration damping foot pads are arranged between the compressor and the bottom plate of the refrigerator cabinet to reduce the vibration noise. Specifically, when the compressor is installed, vibration damping foot pads are respectively installed on its multiple feet. The vibration damping foot pads are usually cylindrical rubber foot pads with through holes in the middle. Rivet screws pass through the through holes to fix the vibration damping foot pads on the bottom plate of the cabinet.

[0004] The role of the compressor vibration damping foot pads in reducing vibration noise in the refrigerator system is mainly reflected in two aspects: one is to weaken the vibration of the compressor itself, and the other is to reduce the vibration transmitted to the compressor support plate, thereby reducing the vibration transmitted to the refrigerator cabinet.

[0005] However, while the compressor vibration damping foot pads play a vibration damping role, the support performance of the compressor also needs to be considered. During the transportation and dropping process, the vibration damping foot pads should not deform too much, so as to avoid problems such as fatigue fracture of the pipeline system connected to the compressor due to excessive deformation.

[0006] In fact, the requirements for the vibration damping foot pads in the refrigerator system under the two working conditions of long-term operation and packaging transportation are contradictory. Long-term operation requires the vibration damping foot pads to have a small stiffness and good vibration isolation performance, while packaging transportation requires the vibration damping foot pads to have a large stiffness to prevent the compressor from shaking too much during transportation and causing damage. The cylindrical rubber foot pads used in the compressor in the related art cannot take into account both good vibration isolation and damping effects and support performance.

[0007] And since most compressors are rotary compressors, a large part of the generated vibration is torsional vibration. The cylindrical rubber foot pads in the related art are mainly used to isolate the vibration of the compressor in the vertical direction, without fully considering the torsional vibration of the compressor, which also makes its vibration isolation and damping effects average.

[0008] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0009] In view of the problems pointed out in the background art, the utility model provides a compressor and a refrigerator, and its foot pad structure can improve the vibration isolation and damping effects and support performance of the compressor.

[0010] To achieve the above-mentioned utility model object, the compressor in some embodiments of the present utility model adopts the following technical solutions to be realized:

[0011] In some embodiments of the present application, a compressor is provided, including:

[0012] A compressor body, with a plurality of mounting parts circumferentially arranged at its bottom;

[0013] A plurality of vibration damping foot pads, arranged in one-to-one correspondence with the plurality of mounting parts; the vibration damping foot pads include:

[0014] A fixing member, having an installation cavity with an open top;

[0015] A rotating member, erected in the installation cavity, and having a first through portion extending vertically, the rotating member is rotationally matched with the fixing member;

[0016] A sliding member, erected in the first through portion; the sliding member is vertically slidably matched with the rotating member, and its top end extends above the rotating member and the fixing member and is connected to the mounting part;

[0017] A first elastic member, arranged in the installation cavity and configured to be elastically deformed in the vertical direction, the first elastic member is located below the sliding member and abuts against the sliding member.

[0018] The compressor in the above technical solution has the following advantages or beneficial effects: On the one hand, the vibration damping foot pad of the compressor includes a fixing member, a rotating member, a sliding member and a first elastic member. The fixing member is the basic part of the whole vibration damping foot pad. The rotating member is rotationally arranged in the installation cavity of the fixing member, that is, it can rotate relative to the fixing member. The sliding member is arranged in the first through portion of the rotating member and can slide up and down vertically relative to the rotating member. The sliding member is connected to the mounting part of the compressor body. A first elastic member is also arranged in the installation cavity of the fixing member. Then when the compressor body is vibrated, it can drive the sliding member to slide up and down. Through the relative friction between the sliding member and the rotating member, and the downward sliding of the sliding member causes the first elastic member to be elastically deformed in the vertical direction, so that the first elastic member can buffer the downward sliding of the sliding member to dissipate the vibration energy of the compressor body in the vertical direction. At the same time, through the rotational friction of the rotating member relative to the fixing member, the torsional vibration energy generated by the rotation of the compressor body is dissipated, significantly improving the vibration isolation and damping effect on the compressor body.

[0019] On the other hand, the vibration damping foot pad is assembled from the above-mentioned multiple parts, and some of these parts can be made of materials with relatively high hardness. For example, the sliding member, the rotating member and the fixing member can be made of plastic material. Compared with the existing rubber foot pads with a single structure, the overall stiffness of the vibration damping foot pad is increased and the supporting performance is improved. In this way, the compressor in the above solution can also meet the requirements of drop transportation.

[0027] In some embodiments of the present application, the rotating member and the fixed member are provided with a mutually cooperating rotating guiding structure for guiding the rotation of the rotating member relative to the fixed member.

[0028] The compressor in the above technical solution has the following advantages or beneficial effects: By providing the rotating guiding structure, the rotation of the rotating member relative to the fixed member is smooth, avoiding jamming, and improving the reliability of the vibration isolation and damping effect on the circumferential torsional vibration.

[0029] In some embodiments of the present application, the vibration damping foot pad further includes:

[0030] The second elastic member is disposed between the rotating member and the fixed member, and is configured such that when the rotating member rotates relative to the fixed member, the second elastic member can generate elastic deformation to provide damping for the rotation of the rotating member.

[0031] The compressor in the above technical solution has the following advantages or beneficial effects: the torsional vibration energy generated by the rotation of the compressor body is also dissipated through the buffering of the second elastic member, further improving the vibration isolation and vibration reduction effect of the torsional vibration of the compressor body.

[0032] In some embodiments of the present application, a receiving cavity is formed on the inner wall of the fixing member and is arranged around the periphery of the rotating member. The second elastic member is located in the receiving cavity, one end of which is connected to the rotating member and the other end is connected to the fixing member.

[0033] The compressor in the above technical solution has the following advantages or beneficial effects: the accommodating cavity is a groove structure formed on the inner wall of the fixing member, so that the second elastic member can be built into the accommodating cavity, thereby making the structure compact and reducing space occupancy.

[0034] In some embodiments of the present application, both ends of the installation cavity are open, the sliding member has a second through-portion extending vertically, and the second through-portion, the first through-portion, and the installation cavity are coaxially arranged.

[0042] A first elastic member, which is configured such that when the sliding member slides vertically downward relative to the rotating member, it drives the first elastic member to generate elastic deformation in the vertical direction to provide damping for the downward sliding of the sliding member.

[0043] The compressor in the above technical solution has the following advantages or beneficial effects: On the one hand, when the compressor body is vibrated, it can drive the sliding member to slide up and down. Through the relative friction between the sliding member and the rotating member and the buffering of the first elastic member, the vibration energy of the compressor body in the vertical direction is dissipated; at the same time, through the rotational friction between the rotating member and the fixing member, the torsional vibration energy generated by the rotation of the compressor body is dissipated, significantly improving the vibration isolation and damping effect on the compressor body.

[0079] and

[0080] In some embodiments of the present application, as Figure 4 shown, the compressor 300 includes a compressor body 310. A plurality of mounting portions 311 are circumferentially arranged at the bottom of the compressor body 310 and serve as the mounting and connecting portions of the compressor body 310.

[0081] In some embodiments of the present application, a horizontal foot plate 312 is welded to the bottom of the compressor body 310. The foot plate 312 extends outward from the compressor body 310, and a plurality of mounting portions 311 are formed on the foot plate 312 and are circumferentially arranged.

[0082] In some embodiments of the present application, as Figures 4 to 7 shown, the compressor 300 includes a plurality of vibration damping foot pads 320, and the plurality of vibration damping foot pads 320 are arranged in one-to-one correspondence with the plurality of mounting portions 311. Each vibration damping foot pad 320 includes a fixing member 321, a rotating member 322, a sliding member 323, and a first elastic member 324.

[0083] Among them, the fixing member 321 is the basic part of the entire vibration damping foot pad 320, which has a mounting cavity 3211 with an open top end, and the fixing member 321 is fixedly connected to the bottom plate of the compressor compartment.

[0084] The rotating member 322 is vertically arranged in the installation cavity 3211. The rotating member 322 has a first through portion 3221 extending vertically, that is, the first through portion 3221 penetrates the rotating member 322 vertically up and down. The rotating member 322 is rotationally matched with the fixing member 321, that is, the rotating member 322 is rotatably arranged in the installation cavity 3211.

[0085] The sliding member 323 is vertically arranged in the first through portion 3221; the sliding member 323 is vertically slidably matched with the rotating member 322, that is, the sliding member 323 can slide up and down relative to the rotating member 322 in the vertical direction. The top end of the sliding member 323 extends above the rotating member 322 and the fixing member 321, and the top end of the sliding member 323 is connected to the installation portion 311.

[0086] The first elastic member 324 is arranged in the installation cavity 3211 and is configured to be elastically deformed in the vertical direction. The first elastic member 324 is located below the sliding member 323 and abuts against the sliding member 323.

[0087] In some embodiments of the present application, the vibration damping foot pad 320 is fixedly connected to the bottom plate of the press chamber through the fixing member 321. The sliding member 323 is connected to the installation portion 311 of the compressor body 310. The rotating member 322 is rotatably arranged in the installation cavity 3211 of the fixing member 321. The sliding member 323 is arranged in the first through portion 3221 of the rotating member 322 and can slide up and down relative to the rotating member 322 in the vertical direction. A first elastic member 324 is also arranged in the installation cavity 3211 of the fixing member 321.

[0088] When the compressor body 310 is vibrated, the vibration in the vertical direction can drive the sliding member 323 to slide up and down. Through the relative friction between the sliding member 323 and the rotating member 322, and the downward sliding of the sliding member 323 causing the first elastic member 324 to generate elastic deformation in the vertical direction, the first elastic member 324 can buffer the downward sliding of the sliding member 323 to dissipate the vibration energy of the compressor body 310 in the vertical direction.

[0089] At the same time, the torsional vibration energy generated by the rotation of the compressor body 310 is dissipated and weakened through the rotational friction between the rotating member 322 and the fixing member 321, significantly improving the vibration isolation and damping effect on the compressor body 310.

[0090] The vibration damping foot pad 320 in some embodiments of the present application is assembled from the above-mentioned multiple parts. Some of the parts can be made of materials with relatively high hardness. For example, the sliding member 323, the rotating member 322, and the fixing member 321 can be made of plastic material. Compared with the existing rubber foot pads with a single structure, the overall stiffness of the vibration damping foot pad 320 is increased and the support performance is improved. Thus, the compressor 300 in some embodiments of the present application can also meet the requirements of drop transportation.

[0091] The vibration damping foot pad 320 improves the vibration isolation and damping effect on the compressor body 310 and enhances the supporting performance. Correspondingly, it can reduce the noise of the refrigerator system and reduce the damage of the system pipeline caused by transportation drops.

[0092] In some embodiments of the present application, the outer contour of the fixing member 321 is cylindrical, and its installation cavity 3211 is a circular installation cavity; correspondingly, the rotating member 322 is cylindrical, and the outer contour of the sliding member 323 is cylindrical. The three are coaxially sleeved in sequence.

[0093] Figure 8 It is a three-dimensional view of the sliding member of the compressor vibration damping foot pad according to the embodiment. Figure 9 It is a three-dimensional view of the rotating member of the compressor vibration damping foot pad according to the embodiment. As Figure 8 、 Figure 9 shown, and in combination with Figure 5 In some embodiments of the present application, the sliding member 323 and the rotating member 322 are provided with a mutually matching sliding guiding structure, and the sliding guiding structure is used to guide the vertical sliding of the sliding member 323 relative to the rotating member 322.

[0094] By setting the sliding guiding structure, the sliding of the sliding member 323 relative to the rotating member 322 is smoother, avoiding jamming and improving the vibration isolation and damping effect in the vertical direction; at the same time, by reasonably setting the specific structure of the sliding guiding structure, the torque generated by the rotation of the compressor body 310 can be transmitted to the rotating member 322 to a greater extent through the sliding member 323, and then the torsional vibration energy is dissipated through the rotational friction between the rotating member 322 and the fixing member 321.

[0095] In some embodiments of the present application, as Figure 8 、 Figure 9 shown, the sliding guiding structure includes a long strip-shaped guiding plate 3231 formed on the outer wall of the sliding member 323 and extending vertically, and a long strip-shaped guiding groove 3222 formed on the inner wall of the rotating member 322 and extending vertically. The guiding plate 3231 is embedded in the guiding groove 3222.

[0096] When the sliding member 323 slides vertically relative to the rotating member 322, the guiding plate 3231 and the guiding groove 3222 are in sliding guiding cooperation, enabling the sliding member 323 to slide vertically stably; and because the guiding plate 3231 is embedded in the guiding groove 3222, the torsion generated by the rotation of the compressor body 310 can be transmitted to the rotating member 322 through the sliding member 323, rotate relative to the fixing member 321, and the torsional vibration energy of the compressor body 310 is consumed and weakened through the rotational friction between the rotating member 322 and the fixing member 321.

[0097] Of course, the sliding guiding structure can also be other structures, such as a guiding groove formed on the outer wall of the sliding member 323 and extending vertically, and a long guiding plate formed on the inner wall of the rotating member 322 and extending vertically, etc., which will not be specifically limited herein.

[0098] In some embodiments of the present application, the bottom end of the installation cavity 3211 is closed, the bottom end of the first elastic member 324 abuts against the bottom end of the installation cavity 3211, and can be connected to the bottom end of the installation cavity 3211 as a whole. The top end of the first elastic member 324 abuts against the bottom end of the sliding member 323, or is connected to the bottom end of the sliding member 323 as a whole.

[0099] Alternatively, in some embodiments of the present application, the bottom end of the installation cavity 3211 is also open. By forming a first stop portion 3212 at the bottom end of the installation cavity 3211, the bottom end of the first elastic member 324 abuts against the first stop portion 3212 and can be connected to the first stop portion 3212 as a whole, referring to Figure 7 and Figure 11 shown.

[0100] The first stop portion 3212 can be an annular integral body, connected to the fixing member 321 as a whole, or can be a plurality of separate block structures arranged at intervals circumferentially along the bottom end of the installation cavity 3211, and each block structure is connected to the fixing member 321 as a whole.

[0101] Through the above structural design of the installation cavity 3211, the first elastic member 324 can be conveniently and stably arranged in the installation cavity 3211, enhancing the integrity of the vibration damping foot pad 320 and facilitating overall disassembly and assembly.

[0102] In some embodiments of the present application, both ends of the installation cavity 3211 are open, the sliding member 323 has a second through portion 3232 extending vertically, and the second through portion 3232, the first through portion 3221, and the installation cavity 3211 are coaxially arranged.

[0103] It is convenient to use a bolt to pass through the installation cavity 3211, the first through portion 3221, and the second through portion 3232 at the same time, connect the sliding member 323 to the installation portion 311 of the compressor body 310, and connect the fixing member 321 to the bottom plate of the press chamber, so as to install the compressor 300 on the bottom plate of the press chamber. There is no need to separately arrange connecting members at the connection between the sliding member 323 and the installation portion 311 of the compressor body 310 and at the connection between the fixing member 321 and the bottom plate of the press chamber, which simplifies the connection structure and improves the installation efficiency.

[0104] Similarly, as in Figure 7 and Figure 11As shown, in some embodiments of the present application, a second stopper 3213 is further formed on the inner wall of the installation cavity 3211, and the bottom end of the rotating member 322 abuts against the second stopper 3213. Thus, the rotating member 322 can be stably arranged in the installation cavity 3211, the integrity of the vibration-damping foot pad 320 is enhanced, and the overall disassembly and assembly are facilitated.

[0105] like Figure 7 and Figure 11 As shown, in some embodiments of the present application, the rotating member 322 and the fixed member 321 are provided with mutually cooperating rotation guide structures, and the rotation guide structures can guide the rotation of the rotating member 322 relative to the fixed member 321.

[0106] By providing a rotation guide structure, the rotating member 322 can rotate smoothly relative to the fixed member 321 to avoid jamming, thereby improving the reliability of the vibration isolation and vibration reduction effect on the circumferential torsional vibration.

[0107] In some embodiments of the present application, Figure 7 , Figure 11 As shown, the rotation guide structure includes a plurality of guide protrusions 3223 formed on the outer wall of the rotating member 322 and arranged circumferentially, and an annular groove 3214 formed on the inner wall of the fixing member 321 and circumferentially surrounding the fixing member 321, and the guide protrusions 3223 are embedded in the annular groove 3214.

[0108] When the rotating member 322 rotates relative to the fixed member 321, the guide protrusion 3223 cooperates with the annular groove 3214 to guide the rotating member 322 relative to the fixed member 321 so that the rotating member 322 can rotate smoothly relative to the fixed member 321, and can also prevent the rotating member 322 from axially separating from the fixed member 321, thereby improving the assembly reliability of the vibration-damping foot pad 320.

[0109] In order to facilitate the smooth insertion of the rotating member 322 into the installation cavity 3211 of the fixed member 321, it is necessary to set an avoidance channel on the inner wall of the fixed member 321 in correspondence with the multiple guide protrusions 3223, and the avoidance channel is located above the annular groove 3214 and communicates with the annular groove 3214. When inserting the rotating member 322, first align the multiple guide protrusions 3223 of the rotating member 322 with each avoidance channel one by one, and then insert the rotating member 322 downward, and when the guide protrusion 3223 reaches the annular groove 3214, rotate the rotating member 322 so that its guide protrusion 3223 rotates in the annular groove 3214 until it is staggered with the avoidance channel.

[0110] Of course, the rotation guide structure may also be other structures, and there is no specific limitation to this.

[0111] In some embodiments of the present application, to improve the dissipation effect of the torsional vibration energy of the compressor body 310, the vibration damping foot pad 320 further includes a second elastic member 330, and the second elastic member 330 is disposed between the rotating member 322 and the fixing member 321. The second elastic member 330 is configured such that when the rotating member 322 rotates relative to the fixing member 321, the second elastic member 330 can undergo elastic deformation to provide damping to the rotation of the rotating member 322.

[0112] That is, the torsional vibration energy generated by the rotation of the compressor body 310 is also dissipated through the buffering of the second elastic member 330, further improving the vibration isolation and damping effect on the torsional vibration of the compressor body 310.

[0113] In some embodiments of the present application, a receiving cavity surrounding the outer periphery of the rotating member 322 is formed on the inner wall of the fixing member 321. The second elastic member 330 is located in the receiving cavity, with one end connected to the rotating member 322 and the other end connected to the fixing member 321.

[0114] In some embodiments of the present application, as Figure 7 、 Figure 10 and Figure 11 shown, the receiving cavity is the above-mentioned annular groove 3214. The second elastic member 330 is located in the annular groove 3214 and extends in an arc shape. One end of the second elastic member 330 is connected to one of the guiding convex blocks 3223 on the outer wall of the rotating member 322, and the other end is connected to the fixing member 321.

[0115] Both ends of the second elastic member 330 can be respectively connected to the guiding convex block 3223 and the fixing member 321 through a pin a.

[0116] Then, the annular groove 3214 cooperates with the guiding convex block 3223. On the one hand, it can guide the rotation of the rotating member 322, and on the other hand, it can also provide space for the arrangement of the second elastic member 330, which is beneficial to reducing structural components and simplifying the overall structure.

[0117] The receiving cavity is a groove structure formed on the inner wall of the fixing member 321, enabling the second elastic member 330 to be built into the receiving cavity, thereby making the structure compact and reducing space occupation.

[0118] The first elastic member 324 and the second elastic member 330 can be springs, elastic rubber blocks or other components with elastic deformation ability, and specific limitations are not required here.

[0119] In some embodiments of the present application, a compressor 300 includes a compressor body 310 and a plurality of vibration damping foot pads 320.

[0120] A plurality of installation parts 311 are circumferentially arranged at the bottom of the compressor body 310.

[0121] A plurality of vibration damping foot pads 320 are provided in one-to-one correspondence with a plurality of mounting portions 311. Each vibration damping foot pad 320 includes a fixing member 321, a rotating member 322, a sliding member 323, and a first elastic member 324.

[0122] Among them, the fixing member 321 is the basic part of the entire vibration damping foot pad 320. It has a mounting cavity 3211 with an open top end. The fixing member 321 is fixedly connected to the bottom plate of the press chamber.

[0123] The rotating member 322 is erected in the mounting cavity 3211. The rotating member 322 has a first through portion 3221 extending vertically, that is, the first through portion 3221 penetrates the rotating member 322 vertically up and down. The rotating member 322 is rotationally matched with the fixing member 321, that is, the rotating member 322 is rotatably arranged in the mounting cavity 3211.

[0124] The sliding member 323 is erected in the first through portion 3221; the sliding member 323 is vertically slidably matched with the rotating member 322, that is, the sliding member 323 can slide up and down relative to the rotating member 322 in the vertical direction. The top end of the sliding member 323 extends above the rotating member 322 and the fixing member 321, and the top end of the sliding member 323 is connected to the mounting portion 311.

[0125] The first elastic member 324 is configured such that when the sliding member 323 slides vertically downward relative to the rotating member 322, it drives the first elastic member 324 to generate elastic deformation in the vertical direction to provide damping for the downward sliding of the sliding member 323, so as to buffer and dissipate the vibration energy of the compressor body 310 in the vertical direction.

[0126] When the compressor body 310 is vibrated, the vertical vibration therein can drive the sliding member 323 to slide up and down. The relative friction between the sliding member 323 and the rotating member 322 and the buffering of the first elastic member 324 dissipate the vibration energy of the compressor body 310 in the vertical direction; at the same time, the torsional vibration energy generated by the rotation of the compressor body 310 is dissipated and weakened through the rotational friction of the rotating member 322 relative to the fixing member 321, significantly improving the vibration isolation and damping effect on the compressor body 310.

[0127] In the description of the above embodiments, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0128] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
