Description

Technical Field

[0001] The present disclosure relates to the technical field of compressors, and in particular to a compressor connection assembly, a compressor assembly, and an air conditioner. Background Art

[0002] As the core power unit of the air-conditioning refrigeration system, the compressor provides a continuous source of power for the refrigerant to circulate throughout the refrigeration system. The storage of refrigerant mainly depends on the liquid accumulator, which is a pressure vessel used to store and supply refrigerant. In order to ensure the stable operation of the compressor and reduce the shaking of the liquid accumulator during operation, it is necessary to adopt the necessary fixed connection method to connect the two. The general connection method includes connecting the two by welding, bolts or clamps, and fixing the bottom of the compressor as a whole by connecting the chassis and foot pads. From the overall structural point of view, although it can play the role of fixing the connection between the compressor and the liquid reservoir, such a connection method is similar to a cantilever beam structure. When the compressor is in normal operation, it will inevitably cause the compressor body to tilt toward the liquid reservoir side, directly acting on the compressor body, causing the center of mass of the compressor to shift, thereby causing the compressor to produce large vibration and shaking during operation, especially when the compressor is in an unstable working condition (such as car air conditioning, ship air conditioning) or encounters harsh external operating environment conditions (such as potholes and muddy roads) during transportation. The vibration and shaking of the entire compressor body are more intense. At this time, the center of mass of the compressor is seriously shifted, which will cause the inlet and outlet air pipes to break, noise and failure of the chassis foot pads, thereby affecting the operating stability of the entire refrigeration system.

[0003] Most existing publicly available technical solutions propose changing the shape, structure, and fixing method of the connecting parts. For example, Patent No. CN202648068U discloses a method using two clamps with openings on their outer rings; Patent No. CN201747608U discloses a method using a small hook on one end of the clamp and a self-tapping screw on the other. All of these patents suffer from shortcomings such as displacement of the center of mass, significant vibration, and shaking during compressor operation. For example, Patent No. CN205014683U discloses a method of adding a bracket assembly to the middle of the clamping device and fixing it to the chassis; Patent No. CN209479661U discloses a method of fixing the clamp to the air conditioner frame via bolts at one end of the clamp. All of these patents modify the shape and structure of the connecting parts and fix them to the air conditioner chassis or frame. However, all of these patents suffer from shortcomings such as not considering the strength of the connected parts, excessively changing the connecting parts' structure, resulting in excessive complexity, difficulty in manufacturing and repair and replacement, and poor adjustability of the connecting parts.

[0004] Since the compressors in the prior art have technical problems such as being unable to simultaneously ensure that the compressor center of mass is stable and not eccentric under operating conditions and reduce the vibration and noise of the compressor, the present invention studies and designs a compressor connection assembly, a compressor assembly and an air conditioner.

[0005] Public content

[0006] Therefore, the technical problem to be solved by the present disclosure is to overcome the defects of the compressor in the prior art that it is impossible to simultaneously ensure that the center of mass of the compressor is stable and not eccentric under operating conditions and reduce the vibration noise of the compressor, thereby providing a compressor connection assembly, a compressor assembly and an air conditioner.

[0007] In order to solve the above problems, the present disclosure provides a compressor connection assembly, which includes:

[0011] The second annular portion is located between the first annular portion and the third annular portion, the first annular portion is located on one side of the second annular portion, and the third annular portion is located on the other side of the second annular portion, and the first annular portion and the third annular portion are symmetrically arranged relative to the second annular portion.

[0012] In some embodiments, the first annular portion is a circular ring structure, which is matched with the cylindrical liquid reservoir;

[0013] The second annular portion is a circular ring structure and is fitted to fit the cylindrical compressor.

[0014] In some embodiments, the third annular portion is a square ring structure, the counterweight component is a square structure, and the square-structured third annular portion accommodates the square-structured counterweight component therein.

[0015] In some embodiments, the compressor connection assembly is a three-section hoop structure, the first annular portion is a first hoop, the second annular portion is a second hoop, and the third annular portion is a third hoop.

[0016] In some embodiments, the first annular portion, the second annular portion, and the third annular portion are integrally formed.

[0017] In some embodiments, a screw hole is further provided at the position where the first annular portion and the second annular portion meet, and the compressor connection assembly further includes a threaded fastener, which is passed through the screw hole to fasten the first annular portion and the second annular portion.

[0018] The present disclosure also provides a compressor assembly, which includes the compressor connection assembly described in any of the preceding items, and also includes a compressor, a liquid reservoir and a counterweight component, the compressor being clamped in the second annular portion, the liquid reservoir being clamped in the first annular portion, and the counterweight component being clamped in the third annular portion.

[0019] In some embodiments, the housing is interference-fitted with the second annular portion; the liquid reservoir is interference-fitted with the first annular portion; and the weight component is threadedly fastened to the third annular portion.

[0020] In some embodiments, the mass of the compressor is defined as m1, the mass of the liquid reservoir is defined as m2, and the mass of the counterweight component is defined as m3. In the cross section, the position of the central axis of the compressor is the center O, the distance between the center of mass of the compressor and the center O is x1, the distance between the center of mass of the liquid reservoir and the center O is x2, and the distance between the center of mass of the counterweight component and the center O is x3. After the counterweight component is clamped in the third annular portion, the overall center of mass position of the compressor assembly coincides with the center O. At this time, the eccentricity of the overall center of mass position is e=0, and e=(m1x1+m2x2+m3x3) / (m1+m2+m3)=0, thereby obtaining the mass of the counterweight component m3.

[0021] In some embodiments, a mounting flange is further included, and the counterweight component is fixedly mounted on the third annular portion via the mounting flange; alternatively, the counterweight component is fixedly connected to the third annular portion by welding or bonding.

[0022] The present disclosure also provides an air conditioner, which includes the compressor assembly described in any of the preceding items.

[0023] The present disclosure provides a compressor connection assembly, a compressor assembly, and an air conditioner, which have the following beneficial effects:

This can ensure that the center of mass of the compressor is in a balanced position to the greatest extent, offset the mass of the liquid reservoir and eliminate the inertia moment generated by the displacement and rotation of the center of mass of the compressor. In this way, the displacement of the center of mass of the compressor can be offset or eliminated, the inertia moment can be reduced, and the vibration noise of the compressor can be reduced, thereby solving the problem of not being able to simultaneously ensure that the center of mass of the compressor is stable and not eccentric under operating conditions and reduce the vibration noise of the compressor.

The connection is very stable and reliable, easy to manufacture, low in investment cost, and convenient to install and maintain.

[0026] 3. Since the present invention adopts the method of adding a counterweight structure to the compressor body, that is, by adding a balancing mass block on the side symmetrically opposite to the eccentricity of the liquid reservoir with respect to the center of mass of the compressor body, the rotational inertia of the compressor in the rotation direction is increased, thereby reducing the vibration level of the compressor and ensuring the stable operation of the compressor.

[0033] like Figure 1-4As shown, the present disclosure provides a compressor connection assembly, which includes:

[0034] The first annular portion 11 is used to be sleeved on the outer periphery of the liquid reservoir 3;

[0035] The second annular portion 12 is configured to be sleeved on the outer periphery of the compressor 2;

[0036] A third annular portion 13 is used to dispose the weight component 4 in the third annular portion 13;

[0037] The second annular portion 12 is located between the first annular portion 11 and the third annular portion 13, the first annular portion 11 is located on one side of the second annular portion 12, and the third annular portion 13 is located on the other side of the second annular portion 12, and the first annular portion 11 and the third annular portion 13 are symmetrically arranged relative to the second annular portion 12.

[0038] The present invention discloses a compressor connecting assembly comprising a first annular portion, a second annular portion and a third annular portion, wherein the first annular portion is used to clamp the liquid reservoir, the second annular portion is used to clamp the compressor, and the third annular portion is used to clamp the counterweight component. The connecting component is designed to have a three-ring symmetrical structure, wherein the compressor is fixedly connected to the compressor in the middle position through the second annular portion, and the counterweight component (connected through the third annular portion) is symmetrically arranged in the opposite direction of the liquid reservoir (connected through the first annular portion). This can ensure that the center of mass of the compressor is in a balanced position to the greatest extent, offset the mass of the liquid reservoir and eliminate the inertia moment generated by the offset rotation of the center of mass of the compressor. In this way, the offset of the center of mass of the compressor can be offset or eliminated, and the inertia moment can be reduced, thereby reducing the vibration noise of the compressor.

[0039] In some embodiments, the first annular portion 11 is a circular ring structure, which is matched with the cylindrical liquid reservoir;

[0040] The second annular portion 12 is a circular ring structure and is fitted to fit the cylindrical compressor.

[0041] This is the preferred structural form of the first annular portion and the second annular portion disclosed in the present invention. By setting them both in the form of circular ring structures, they can respectively cooperate with the cylindrical liquid reservoir and the cylindrical compressor housing and be firmly stuck on their outer circumferential surfaces.

[0042] In some embodiments, the third annular portion 13 is a square ring structure, and the counterweight component 4 is a square structure. The square-shaped third annular portion 13 accommodates the square-shaped counterweight component 4 therein. This is the preferred structural form of the third annular portion of the present disclosure. The square ring structure can effectively arrange the counterweight component into a square structure, and the square-shaped counterweight component can be securely fixed to the square-shaped third annular portion.

[0043] In some embodiments, the compressor connection assembly has a three-section hoop structure, wherein the first annular portion 11 is a first hoop, the second annular portion 12 is a second hoop, and the third annular portion 13 is a third hoop. This is a further preferred structural form of the compressor connection assembly disclosed herein, wherein the first annular portion is a first hoop that can be securely clamped to the outer periphery of the liquid reservoir, the second annular portion is a second hoop that can be securely clamped to the outer periphery of the compressor, and the third annular portion is a third hoop that can be securely clamped to the outer periphery of the square-structured counterweight component.

[0044] In some embodiments, the first annular portion 11, the second annular portion 12, and the third annular portion 13 are integrally formed. By integrally forming the three annular portions, the compressor, the liquid reservoir, and the counterweight component can be securely connected, vibration and noise can be reduced, and the center of mass eccentricity can be adjusted to the center axis of the compressor, reducing eccentric torque.

[0045] In some embodiments, a screw hole is further provided at the location where the first annular portion 11 and the second annular portion 12 meet, and the compressor connection assembly further includes a threaded fastener 5, which is inserted into the screw hole to fasten the first annular portion 11 and the second annular portion 12. The present disclosure also utilizes the provision of the screw hole and the threaded fastener to effectively tighten the connection between the first annular portion and the second annular portion to clamp the compressor and the liquid accumulator, respectively, and to loosen the threaded fastener to effectively remove the compressor connection assembly from the compressor and the liquid accumulator.

[0046] The present disclosure also provides a compressor assembly, which includes the compressor connection assembly 1 described in any of the previous items, and also includes a compressor 2, a liquid reservoir 3 and a counterweight component 4, the compressor 2 is clamped in the second annular portion 12, the liquid reservoir 3 is clamped in the first annular portion 11, and the counterweight component 4 is clamped in the third annular portion 13.

[0047] The present invention adopts the design of a three-ring symmetrical connector (clamp) structure, which not only ensures the fixed connection between the compressor and the liquid accumulator, but also improves the operating stability of the compressor;

[0048] The design of adding counterweights to the clamps has a compact structure and reasonable space layout, ensuring that the center of mass of the compressor is stable and does not shift during operation, reducing vibration or shaking of the compressor body, ensuring stable operation of the compressor and improving comfort.

[0049] The design of the integrated structure of the clamp allows the inner surface of the clamp ring to fit the outer surface of the compressor and the liquid receiver to the greatest extent possible, making the connection very stable and reliable, and easy to install, disassemble and repair;

[0050] The symmetrically arranged connector design, that is, the counterweight and the liquid reservoir are fixedly connected to both sides of the compressor through the rings at both ends of the connector, has a simple structure, is easy to assemble, has a low manufacturing cost, and is easy to promote.

[0051] Since the present invention designs the connector into a three-ring symmetrical structure, the compressor is fixedly connected to the middle position via the middle hoop (i.e., the second hoop), and the counterweight (connected via the third hoop) is symmetrically arranged in the opposite direction of the liquid accumulator (connected via the first hoop), it can ensure that the center of mass of the compressor is in a balanced position to the greatest extent, offset the mass of the liquid accumulator and eliminate the inertia moment generated by the offset rotation of the compressor center of mass, thereby offsetting or eliminating the offset of the compressor center of mass;

[0052] Since the present invention provides an integrated connector structure, the connector structure is greatly simplified. The inner surface of each clamp ring can fit the outer surface of the compressor, liquid accumulator and counterweight to the greatest extent possible, and then they are fixed and tightened by bolts or screws. The connection is very stable and reliable, easy to manufacture, low in investment cost, and convenient to install and maintain.

[0053] Since the present invention adopts the method of adding a counterweight structure to the compressor body, that is, by adding a balancing mass block on the side symmetrically opposite to the eccentricity of the liquid reservoir with respect to the center of mass of the compressor body, the rotational inertia of the compressor in the rotation direction is increased, thereby reducing the vibration level of the compressor and ensuring the stable operation of the compressor.

[0054] In some embodiments, the compressor 2 is interference-fitted with the second annular portion 12 ; the liquid reservoir 3 is interference-fitted with the first annular portion 11 ; and the weight component 4 is threadedly fastened with the third annular portion 13 .

[0055] The present disclosure provides a novel fixed connection device for connecting a compressor and a liquid accumulator. The overall connection structure adopts a three-ring symmetrical design. The compressor is fixedly connected in the middle position by an intermediate hoop (i.e., the second hoop), and a counterweight (connected by a third hoop) is symmetrically arranged in the opposite direction of the liquid accumulator (connected by the first hoop). This can ensure that the center of mass of the compressor is in a balanced position to the greatest extent, reduce vibration or shaking of the compressor, and ensure stable operation of the compressor.

[0056] The compressor connection assembly is fixed and tightened by bolts, so that the inner surfaces of the second and first clamps can fit the outer surfaces of the compressor and the liquid reservoir to the greatest extent. The connection is stable and reliable, easy to process and manufacture, with low investment cost and convenient installation and maintenance. A counterweight structure is added to the compressor body, that is, a balancing mass block is added on the side symmetrically opposite to the eccentricity of the compressor body's center of mass toward the liquid reservoir, which plays a role in offsetting the mass of the liquid reservoir and eliminating the rotational inertia moment of the compressor center of mass offset. In this way, the compressor center of mass offset can be offset or eliminated, the compressor vibration can be reduced, and the stable operation of the compressor can be ensured.

[0057] In some embodiments, the mass of the compressor 2 is defined as m1, the mass of the liquid reservoir 3 is defined as m2, and the mass of the counterweight component 4 is defined as m3. In the cross section, the position of the central axis of the compressor 2 is the center O, the distance between the center of mass of the compressor 2 and the center O is x1, the distance between the center of mass of the liquid reservoir 3 and the center O is x2, and the distance between the center of mass of the counterweight component 4 and the center O is x3. After the counterweight component 4 is clamped in the third annular portion 13, the overall center of mass position of the compressor assembly coincides with the center O. At this time, the eccentricity of the overall center of mass position is e=0, and e=(m1x1+m2x2+m3x3) / (m1+m2+m3)=0, and the mass of the counterweight component m3 is obtained.

[0058] In order to eliminate or offset the problem of the center of mass of the compressor body shifting toward the liquid reservoir during normal operation, reduce the vibration and noise of the compressor during operation, and ensure stable operation of the compressor, this embodiment mainly provides a compressor body connector structure. The compressor connector structure involved in this application mainly consists of a first hoop, a second hoop, a third hoop, a counterweight, bolts, screws, a compressor, and a liquid reservoir.

[0059] The connector is used to connect the compressor and the liquid receiver. Figure 1 and Figure 2 As shown in FIG, when the compressor is in normal operating conditions, the rotor in the compressor body is in a high-speed running state, which will inevitably generate a centrifugal inertia moment. The connection between the compressor and the accumulator is similar to a cantilever beam structure, which will inevitably generate a reverse resisting centrifugal moment, causing the center of mass of the compressor to shift. Specifically, as shown in FIG. Figure 3 As shown in the figure, when the center of mass of the compressor is offset, the eccentricity is e. In order to offset or eliminate the displacement of the center of mass of the compressor to the greatest extent, ensure that the center of mass of the compressor is in a balanced position, and reduce the vibration or shaking of the compressor, the connecting structure is designed into a three-ring symmetrical structure, as shown in the figure. Figure 3As shown, the counterweight (connected by the third hoop) is symmetrically arranged in the opposite direction of the liquid reservoir (connected by the first hoop). After further adding the counterweight, the compressor body must be in a balanced position, that is, the eccentricity e = 0, so the mass of the counterweight can be calculated. The eccentricity calculation formula is: e = (m1x1 + m2x2 + m3x3) / (m1 + m2 + m3) = 0, where m1, m2, x1, x2, x3 are all known numbers (such as Figure 4 As shown), the counterweight mass (m3) can be calculated. This design implementation method can not only ensure that the center of mass of the compressor is in a balanced position to the greatest extent, but also reduce the inertia moment caused by the rotation of the center of mass offset, thereby reducing the vibration or shaking of the compressor.

[0060] Specifically, the connecting piece is set to an integrated structure, such as Figure 4 As shown, it can not only simplify the structure of the connector to the greatest extent, but also ensure that the inner surface of each clamp ring can fit the contact surface of the compressor, the liquid reservoir and the counterweight to the greatest extent. The structure is compact, the space is reasonable, and the processing and manufacturing are easy. Furthermore, the compressor is fixed in the middle position by the middle hoop (i.e., the second hoop), and the counterweight (connected by the third hoop) is symmetrically arranged in the opposite direction of the liquid reservoir (connected by the first hoop), and then fixedly connected by bolts. The connection is very stable and reliable.

[0061] Specifically, a counterweight structure is added to the compressor body, such as Figure 1 As shown in FIG, by adding a balancing mass block on the side of the compressor body mass center symmetrically in the opposite direction of the eccentricity of the liquid reservoir, the rotational inertia of the compressor in the rotation direction is increased, thereby reducing the vibration level of the compressor and ensuring the stable operation of the compressor. Furthermore, by adding four flanges (such as Figure 2 As shown in the figure, the flange and the counterweight are fixed in position by welding, a fixing hole is opened on the flange folding section, and then the counterweight is fixed to the matching hole of the third hoop by screws. The connection is firm and reliable, the investment cost is low, and the installation, maintenance and replacement are also convenient.

[0062] Specifically, from the perspective of connector strength and economy, the overall structure of the connector can be manufactured using sheet metal, and from the perspective of manufacturing process and economy, the counterweight structure can be manufactured using cast iron.

[0063] In some embodiments, a mounting flange 6 is further included, and the counterweight component 4 is fixedly mounted on the third annular portion via the mounting flange; alternatively, the counterweight component 4 is fixedly connected to the third annular portion 13 by welding or bonding.

The above description is merely a preferred embodiment of the present disclosure.
