Description

Technical Field

[0001] The present application belongs to the technical field of refrigerators, and in particular, relates to a compressor assembly and a refrigeration device. Background Art

[0002] Refrigerators are usually provided with a compressor compartment to accommodate the compressor. When installing the compressor, the compressor is placed at a preset position on the bottom plate of the compressor compartment, and then the compressor is welded to the bottom plate by welding feet to fix the compressor, thereby preventing the compressor from shifting during operation or movement of the refrigerator.

[0003] However, in this connection method, when the compressor is in operation, the vibration of the compressor will be transmitted to the bottom plate of the compressor compartment through the welding feet. Since the bottom plate itself has a natural frequency, when the excitation frequency transmitted by the compressor to the bottom plate is the same as or close to the natural frequency of the bottom plate itself, resonance will occur, thereby increasing the noise of the refrigerator. Utility Model Content

[0004] The embodiments of the present application provide a compressor assembly and a refrigeration device to solve the problem that the compressor in the existing refrigerator is fixed to the bottom plate of the machine compartment by welding. When the excitation frequency transmitted by the compressor to the bottom plate is the same as or close to the natural frequency of the bottom plate itself, resonance will occur, thereby increasing the noise of the refrigerator.

[0005] The present application provides a compressor assembly, which is applied to a refrigeration device, including:

[0006] The cabin comprises a first plate body and a second plate body which are arranged opposite to each other along the direction of gravity;

[0007] A compressor body, movably arranged on a side of the first plate body facing the second plate body;

[0008] A connecting member, detachably connected between the compressor body and the second plate body;

[0009] The connection strength between the connecting member and the compressor body is adjustable to adjust the excitation frequency of the compressor body on the first plate body and to adjust the excitation frequency of the compressor body on the second plate body.

[0010] Optionally, the connecting member comprises a connecting belt;

[0011] The connecting belt includes a limiting end and an adjusting end opposite to each other. The adjusting end passes through the compressor body and the second plate body in sequence and is locked and fixed with the limiting end.

[0012] Optionally, the limiting end includes a limiting ring;

[0013] The adjusting end includes a plurality of limiting protrusions arranged at intervals along the length direction of the connecting belt;

[0014] The adjusting end is inserted into the limiting ring, and one of the limiting protrusions is fixedly engaged with the limiting ring.

[0015] Optionally, the connecting piece is elastic.

[0016] Optionally, a first hanging hole is provided on a side of the compressor body facing the second plate body, and a second hanging hole is provided on a side of the second plate body facing the compressor body. The connecting member is passed through the first hanging hole and the second hanging hole to connect the compressor body and the second plate body.

[0017] Optionally, the connecting piece further comprises:

[0018] A rotating shaft, arranged on the second plate body;

[0019] A hanging rope, one end of which is wound around the rotating shaft and the other end of which is connected to the compressor body;

[0020] The rotation of the rotating shaft drives the hanging rope to be retracted and released, so as to adjust the connection strength between the hanging rope and the compressor body.

[0021] Optionally, a rotating member is further included, and the torque of the rotating member is adjustable to drive the rotating shaft to rotate to a set position.

[0022] Optionally, the connecting member further comprises a telescopic pump, and the telescopic pump is arranged on the second plate body;

[0023] The telescopic pump comprises a telescopic end facing the compressor body, the telescopic end is connected to the compressor body, and drives the compressor body to approach or move away from the second plate body.

[0024] Optionally, there are a plurality of connecting members, which are arranged at intervals between the compressor body and the second plate body.

[0026] case;

[0027] The compressor assembly as described above is arranged in the shell.

[0028] In the compressor assembly provided in the embodiment of the present application, there is tension or pressure between the compressor body and the first plate body and the second plate body, that is, part of the vibration generated by the compressor body during operation is transmitted to the first plate body, and the other part is transmitted to the second plate body. Since the natural frequencies of the first plate body and the second plate body are different, when the compressor body resonates with the first plate body and / or the second plate body, the tension between the compressor body and the second plate body can be adjusted by adjusting the connection strength between the connecting piece and the compressor body. By changing the tension between the compressor body and the second plate body, the vibration intensity transmitted from the compressor body to the second plate body changes, thereby changing the excitation frequency of the compressor body for the second plate body.

[0029] At the same time, since the gravity of the compressor body is constant, when the tension value between the compressor body and the second plate body changes, the pressure of the compressor body on the first plate body will also change accordingly, causing the vibration intensity transmitted by the compressor body to the first plate body to change, thereby changing the excitation frequency of the compressor body on the first plate body.

[0030] Therefore, by adjusting the excitation frequency of the compressor body for the first plate and the second plate, the excitation frequency of the compressor body for the first plate is staggered with the natural frequency of the first plate, and the excitation frequency of the compressor body for the second plate is staggered with the natural frequency of the second plate, thereby avoiding resonance between the compressor body and the first plate and / or the second plate.

[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0051] The embodiment of the present application provides a compressor assembly and a refrigeration device to solve the problem that the compressor in the existing refrigerator is fixed to the bottom plate of the machine compartment by welding. When the excitation frequency transmitted by the compressor to the bottom plate is the same as or close to the natural frequency of the bottom plate itself, resonance will occur, thereby increasing the noise of the refrigerator. This will be explained in conjunction with the accompanying drawings below.

[0052] The present application embodiment provides a compressor assembly for use in a refrigeration device. Figure 1 , Figure 1The first structural schematic diagram of the compressor assembly provided in the embodiment of the present application, the compressor assembly includes a machine chamber, a compressor body 3 and a connecting piece. The machine chamber includes a first plate body 1 and a second plate body 2 arranged relatively to each other along the direction of gravity; the compressor body 3 is movably arranged on the first plate body 1 on the side facing the second plate body 2, specifically, the compressor body 3 is placed on the first plate body 1; the connecting piece is detachably connected between the compressor body 3 and the second plate body 2. Among them, the connection strength between the connecting piece and the compressor body 3 is adjustable to adjust the excitation frequency of the compressor body 3 to the first plate body 1, and adjust the excitation frequency of the compressor body 3 to the second plate body 2.

[0053] In the compressor assembly provided in the embodiment of the present application, there is tension or pressure between the compressor body 3 and the first plate body 1 and the second plate body 2, that is, part of the vibration generated by the compressor body 3 during operation is transmitted to the first plate body 1, and the other part is transmitted to the second plate body 2. Since the natural frequencies of the first plate body 1 and the second plate body 2 are different, when the compressor body 3 resonates with the first plate body 1 or the second plate body 2, or the compressor body 3 resonates with the first plate body 1 and the second plate body 2 at the same time, the tension between the compressor body 3 and the second plate body 2 can be adjusted by adjusting the connection strength between the connecting piece and the compressor body 3. By changing the tension between the compressor body 3 and the second plate body 2, the vibration intensity transmitted from the compressor body 3 to the second plate body 2 changes, thereby changing the excitation frequency of the compressor body 3 for the second plate body 2.

[0054] At the same time, since the gravity of the compressor body 3 is constant, when the tension value between the compressor body 3 and the second plate body 2 changes, the pressure of the compressor body 3 on the first plate body 1 will also change accordingly, causing the vibration intensity transmitted by the compressor body 3 to the first plate body 1 to change, thereby changing the excitation frequency of the compressor body 3 on the first plate body 1.

[0055] Therefore, by adjusting the excitation frequency of the compressor body 3 for the first plate body 1 and the second plate body 2, the excitation frequency of the compressor body 3 for the first plate body 1 is staggered with the natural frequency of the first plate body 1, and the excitation frequency of the compressor body 3 for the second plate body 2 is staggered with the natural frequency of the second plate body 2, thereby avoiding resonance between the compressor body 3 and the first plate body 1 or the second plate body 2, or resonance between the compressor body 3 and the first plate body 1 and the second plate body 2 at the same time.

[0056] It should be noted that the connecting piece provided in the embodiment of the present application generates a pulling force on the compressor body 3 that deviates from the direction of gravity, but the pulling force value is less than the gravity of the compressor body 3, that is, it is ensured that there is pressure or tension between the compressor body 3 and the first plate body 1 and the second plate body 2 at the same time, and thus the vibration generated during the operation of the compressor body 3 can be transmitted to the first plate body 1 in part and to the second plate body 2 in another part, thereby avoiding the situation where the compressor body 3 is only connected to the first plate body 1 or the compressor body 3 is only connected to the second plate body 2.

[0057] Optionally, see Figure 2 , Figure 2 for Figure 1 In the partial enlarged view of point A in the middle, the connecting part includes a connecting belt 4; the connecting belt 4 includes a relative limiting end 41 and an adjusting end 42, and the adjusting end 42 passes through the compressor body 3 and the second plate body 2 in sequence and is locked and fixed with the limiting end 41.

[0058] The adjustment end 42 and the limit end 41 are not further defined herein. In some examples, see Figure 3 , Figure 3 The schematic diagram of the structure of the connector provided in the embodiment of the present application in some examples, the limit end 41 includes a limit ring; the adjustment end 42 includes a plurality of limit protrusions 421 arranged at intervals along the length direction of the connecting belt 4; the adjustment end 42 is inserted into the limit ring, and one of the limit protrusions 421 is clamped and fixed with the limit ring. When it is necessary to adjust the connection strength between the compressor body 3 and the second plate body 2, different limit protrusions 421 of the adjustment end 42 can be clamped and fixed with the limit ring. For example, when it is necessary to increase the connection strength between the compressor body 3 and the second plate body 2, the limit protrusion 421 on the side of the adjustment end 42 close to the limit end 41 is clamped and fixed with the limit ring; when it is necessary to reduce the connection strength between the compressor body 3 and the second plate body 2, the limit protrusion 421 on the side of the adjustment end 42 away from the limit end 41 is clamped and fixed with the limit ring.

[0059] In other examples, the connector may be elastic, e.g. Figure 4 and Figure 5 , Figure 4 This is a second structural schematic diagram of a compressor assembly provided in an embodiment of the present application. Figure 5 for Figure 4In the partial enlarged view of the B in the middle, the connecting member can be an elastic rope. Due to the elastic force of the elastic rope itself, when the compressor body 3 transmits vibration to the second plate body 2 through the elastic rope, the elasticity of the elastic rope itself can offset part of the vibration intensity, thereby weakening the vibration intensity transmitted from the compressor body 3 to the second plate body 2, so as to change the connection strength between the compressor body 3 and the second plate body 2. Further, the elastic rope can include a variety of elastic ropes with different elastic force values ​​and elastic ropes of different lengths. When used, further selection is made according to the specific parameters of the compressor body 3 and the natural frequency parameters of the second plate body 2. At this time, the shape of the elastic rope is not further limited. For example, the elastic rope can be in the shape of a strip, and the two ends of the strip elastic rope can be respectively hung and bound with the compressor body 3 or the second plate body 2, or in the shape of a ring, and the ring-shaped elastic rope can be glued and fixed.

[0060] In other examples, the connecting member may be a fixed ring, which includes a fixed section and a rotating section, one end of the rotating section is rotationally connected to the fixed section, and the other end is magnetically connected to the fixed section. When in use, the rotating section is first passed through the compressor body 3 and the second plate body 2 in sequence, and then the rotating section is rotated so that the other end of the rotating section is magnetically fixed to the fixed section. Here, the fixed ring may be made of metal.

[0061] Optionally, a first hanging hole 31 is provided on the side of the compressor body 3 facing the second plate body 2, and a second hanging hole 21 is provided on the side of the second plate body 2 facing the compressor body 3, and a connecting piece is passed through the first hanging hole 31 and the second hanging hole 21 to connect the compressor body 3 and the second plate body 2.

[0062] The shapes of the first hanging hole 31 and the second hanging hole 21 are not further limited here, for example, they can be round holes or square holes, etc. The number and position of the first hanging hole 31 and the second hanging hole 21 are not further limited either, for example, there can be two first hanging holes 31, and the line connecting the midpoint of the line connecting the two first hanging holes 31 and the center of mass of the compressor body 3 is parallel to the direction of gravity. At this time, the connecting member can pass through the two first hanging holes 31 on the compressor body 3 in sequence, and there can be one second hanging hole 21, and the line connecting the second hanging hole 21 and the midpoint of the line connecting the two first hanging holes 31 is parallel to the direction of gravity, so as to ensure that the tension of the connecting member on the compression body will not cause the compressor body 3 to tilt, thereby affecting the operation of the compressor body 3. For another example, there are two first hanging holes 31 and two second hanging holes 21, each first hanging hole 31 is arranged corresponding to a second hanging hole 21 in the direction of gravity, and the line connecting the midpoint of the line connecting a pair of first hanging holes 31 and the center of mass of the compressor body 3 is parallel to the direction of gravity.

[0063] For other examples, see Figure 6 , Figure 6The third structural schematic diagram of the compressor assembly provided in the embodiment of the present application, the connecting member also includes a rotating shaft 5 and a hanging rope 6. The rotating shaft 5 is arranged on the second plate body 2; one end of the hanging rope 6 is rolled up on the rotating shaft 5, and the other end is connected to the compressor body 3; the rotating shaft 5 rotates to drive the hanging rope 6 to be retracted and released, so as to adjust the connection strength between the hanging rope 6 and the compressor body 3. Furthermore, a hook may be provided at one end of the hanging rope 6 close to the compressor body 3, and the hanging rope 6 is hung in the first hanging hole 31 on the compressor body 3 through the hook. That is, the tension between the hanging rope 6 and the compressor body 3 can be adjusted by rotating the rotating shaft 5. For example, when it is necessary to increase the connection strength between the compressor body 3 and the second plate body 2, the hanging rope 6 is appropriately tightened; when it is necessary to reduce the connection strength between the compressor body 3 and the second plate body 2, the hanging rope 6 is appropriately loosened.

[0064] Optionally, the compressor assembly provided in the embodiment of the present application also includes a rotating member, and the torque of the rotating member is adjustable to drive the rotating shaft 5 to rotate to a set position. Specifically, the rotating member can be a torque wrench. When in use, the preset torque is set to the torque wrench first, and then the wrench is rotated. There is no need to manually check whether the rotation position of the wrench meets the requirements. The operation is simple, time-saving and efficient. In addition, since the torque of the torque wrench is adjustable, the precision control of the connection strength between the compressor body 3 and the second plate body 2 is also improved. Correspondingly, the two ends of the rotating shaft 5 can be provided with a matching portion for the torque wrench to clamp and then drive the rotating shaft 5 to rotate to a preset position through the torque wrench.

[0065] For other examples, see Figure 7 , Figure 7 The fourth structural schematic diagram of the compressor assembly provided in the embodiment of the present application, the connecting member also includes a telescopic pump 7, and the telescopic pump 7 is arranged on the second plate body 2; the telescopic pump 7 includes a telescopic end 71 facing the compressor body 3, and the telescopic end 71 is connected to the compressor body 3, and drives the compressor body 3 to approach or move away from the second plate body 2. Further, a hook or a hanging rope 6 may be provided on the side of the telescopic end 71 close to the compressor body 3, and the telescopic end 71 is connected to the compressor body 3 by the hook or the hanging rope 6. Specifically, the telescopic pump 7 can be a hydraulic pump, and further, the hydraulic pump can be a plunger pump. That is, the compressor body 3 is driven to approach or move away from the second plate body 2 through the telescopic movement of the telescopic pump 7.

[0066] Optionally, there are multiple connecting members and they are spaced apart between the compressor body 3 and the second plate body 2. Furthermore, the combined force of the pulling force of the multiple connecting members on the compressor body 3 extends along the direction of gravity to ensure that the compressor body 3 will not tilt and avoid affecting the operation of the compressor body 3.

[0067] The present application also provides a refrigeration device.
