Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor and a refrigeration device. Background Art

[0002] The compressor is the core component of the refrigeration system. For example, a rotary compressor generally includes a compressor main body and a liquid receiver, and the liquid receiver is connected to the compressor main body through a connecting pipe. In order to ensure the stable installation of the liquid receiver, the liquid receiver is usually connected to the outer shell of the compressor main body through a bracket. In the actual production process, due to the lateral offset of the installation position of the connecting pipe, this lateral offset phenomenon is amplified at the installation position of the liquid receiver. Therefore, it is easy to occur that after the liquid receiver contacts the welding arm of the bracket, it cannot contact the backrest of the bracket, resulting in large fluctuations in the rotational fixed frequency of the liquid receiver; it is also easy to occur that the liquid receiver contacts one welding arm and has too large a gap with the other welding arm, resulting in problems such as false soldering and welding through.

[0036] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0039] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "install", "connect", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0040] Refrigeration systems are installed in refrigeration equipment such as air conditioners and refrigerators to control the ambient temperature or the temperature inside the equipment. The refrigeration system includes components such as a compressor, an evaporator, a condenser, and a throttling device. The compressor is the core component of the refrigeration system and is used to compress the refrigerant.

[0041] The compressor in one embodiment of the present utility model is a rotary compressor commonly used in air conditioners. The rotary compressor includes a compressor main body and a liquid receiver. The compressor main body includes structures such as a compressor housing, a pump body assembly, and a motor assembly. The pump body assembly and the motor assembly are installed inside the compressor housing. The motor assembly drives the crankshaft to rotate, and the crankshaft compresses the refrigerant entering the pump body assembly during rotation.

[0042] The lower part of the liquid receiver is connected to the compressor housing through a connecting pipe, and the connecting pipe transports the refrigerant in the liquid receiver to the inlet of the pump body assembly. The liquid receiver is also connected to the compressor housing through a bracket. Since the natural frequency of the upper part of the liquid receiver rotating is relatively low, resonance is likely to occur during the operation of the compressor, thereby causing the pipeline vibration of the refrigeration equipment and generating low-frequency noise that is more harmful to the human body.

[0043] In order to increase the fixed frequency of the upper part of the liquid receiver rotating, the bracket in the related art adds two constraints on the rotating direction of the liquid receiver, making the liquid receiver in an overconstrained state in the rotating direction, strengthening the rotating stiffness of the liquid receiver to a greater extent, and increasing the natural frequency of the upper part of the liquid receiver rotating.

[0044] However, during the actual production process, due to the existence of a lateral offset in the installation position of the connecting pipe (the offset along the circumferential direction of the liquid receiver, the same hereinafter), this lateral offset phenomenon is amplified at the installation position of the liquid receiver. Due to the existence of the lateral offset, the following problems are likely to occur:

[0045] 1) When the lateral offset is too large, since the welding arm of the bracket is closer to the liquid receiver than the backrest, it is easy to occur that after the liquid receiver contacts the welding arm, it cannot contact the backrest, resulting in the situation that the liquid receiver cannot be guaranteed to be close to the backrest, leading to large fluctuations in the rotating natural frequency of the liquid receiver;

[0046] 2) To ensure that the liquid receiver is close to the backrest, the designed size of the envelope circle of the welding arm is larger than the envelope circle size of the liquid receiver, that is, there are gaps between the welding arms on both sides and the liquid receiver. Therefore, when the liquid receiver has a lateral offset, it is easy to occur that one welding arm contacts the liquid receiver while the gap between the other welding arm and the liquid receiver is too large. In this case, problems such as virtual soldering and soldering through are likely to occur;

[0047] 3) Since the liquid reservoir is in an overconstrained state, it is very difficult to ensure both the welding arm and the liquid reservoir, and the backrest and the liquid reservoir, two lateral constraint pairs, during the manufacturing process. Although the gap between the welding arm and the liquid reservoir is increased to ensure backrest attachment, due to the large lateral offset of the liquid reservoir, there will still be manufacturing problems such as the backrest not fitting well with the liquid reservoir, and excessive lateral clearance between the welding arm and the liquid reservoir resulting in false soldering or soldering through.

[0048] To solve the above problems, as shown in Figure 1 and Figure 2 A compressor according to an embodiment of the present invention includes a compressor main body 100, a liquid reservoir 200, and a bracket 300. The compressor main body 100 includes a compressor housing 110, and the compressor housing 110 generally includes an upper housing 111, a main housing 112, and a lower housing 113. The upper housing 111 and the lower housing 113 are respectively fixedly connected to the upper and lower ends of the main housing 112. The liquid reservoir 200 is installed on the main housing 112 through the bracket 300. As an alternative embodiment, the liquid reservoir 200 can also be installed at other positions of the compressor housing 110.

[0049] As shown in Figure 2 and Figure 3 The liquid reservoir 200 according to an embodiment of the present invention includes a liquid reservoir housing 210 and a connecting ring 220. The connecting ring 220 is connected to the outer wall of the liquid reservoir housing 210. The connecting ring 220 is configured as a metal ring and is fixed to the liquid reservoir housing 210 by welding. The connecting ring 220 is a solid structure, thus effectively avoiding the liquid reservoir housing 210 from being welded through during the welding process. As an alternative embodiment, the connecting ring 220 can also be a hollow structure, and the inner cavity of the connecting ring 220 is not communicated with the inside of the liquid reservoir housing 210, so as to avoid affecting the sealing performance of the liquid reservoir 200 and causing defects after the connecting ring 220 is welded through during the welding process.

[0050] As another alternative embodiment, the liquid reservoir 200 is configured to be divided into upper and lower parts at the connecting ring 220, and the upper and lower parts are welded by butt welding to form a combined structure of the liquid reservoir housing 210 and the connecting ring 220.

[0051] As still another alternative embodiment, the upper cover body (i.e., cup A) of the liquid reservoir housing 210 is elongated, and the middle housing (i.e., cup C) is shortened, and the brim of the upper cover body protrudes outward as the connecting ring 220.

[0052] As shown in Figure 4 and Figure 5As shown in the figure, the bracket 300 of the embodiment of the present utility model includes two fixing plates 310, two wing plates 320 and two welding arms 330. The two fixing plates 310 are fixedly connected to the outer wall of the compressor housing 110, thereby fixing the bracket 300 to the compressor housing 110. The two fixing plates 310 are arranged at intervals along the circumferential direction of the compressor housing 110, and the two fixing plates 310 are symmetrically arranged with respect to the center line of the liquid receiver 200. The two wing plates 320 are respectively connected to the opposite sides of the two fixing plates 310, and the two welding arms 330 are respectively connected to the two wing plates 320. The welding arms 330 are used to fix the bracket 300 to the liquid receiver housing 210. The bracket 300 is configured into two opposite parts, and the welding arms 330 extend in opposite directions. The welding arms 330 include two welding claws 331 arranged at intervals along the height direction of the compressor housing 110. The liquid receiver 200 is loaded into the bracket 300 from the opening where the welding arms 330 extend. The welding claws 331 are arranged at intervals from the outer wall of the liquid receiver housing 210. The connecting ring 220 is inserted into the gap between the two welding claws 331, and the welding claws 331 located on the upper and lower sides of the connecting ring 220 are fixedly connected to the connecting ring 220. In order to enable the connecting ring 220 to be smoothly inserted into the gap between the two welding claws 331, the two welding claws 331 are arranged parallel to each other.

[0053] It should be noted that each welding arm 330 may also be provided with three, four or more welding claws 331, and the outer wall of the liquid receiver housing 210 may also be provided with two, three or more connecting rings 220. Define the number of welding claws 331 of each welding arm 330 as N1, and the number of connecting rings 220 as N2. The number of welding claws 331 N1 and the number of connecting rings 220 N2 satisfy: N2 = N1 - 1. Therefore, each connecting ring 220 is respectively arranged in the gap between the corresponding two welding claws 331.

[0054] Referring to Figure 5 、 Figure 6 and Figure 7 As shown in the figure, through the matching structure of the connecting ring 220 and the two welding claws 331 in the embodiment of the present utility model, the lateral matching gap (i.e., Figure 5 the left-right matching gap in Figure 6The fitting clearance in the up-and-down direction (the same applies hereinafter) suppresses the influence of the lateral offset of the connecting pipe 230 on the installation of the liquid accumulator 200, and improves the problem of poor soldering caused by the excessive lateral clearance between the welding claws 331 and the liquid accumulator housing 210. Since the connection method of the liquid accumulator 200, which is welded and fixed between the liquid accumulator housing 210 and the welding arm 330, is overconstrained in the rotational direction, it is changed to the longitudinal connection method between the connection ring 220 and the welding claws 331, improving the overconstrained situation, strengthening the rotational stiffness of the liquid accumulator 200, increasing the fixed frequency of the liquid accumulator 200, and reducing the low-frequency noise of the compressor.

[0055] Moreover, in this embodiment, the positioning of the liquid accumulator 200 and the compressor housing 110 is realized through the structure of the connection ring 220 and the two welding claws 331. In actual production, during the welding process of the connecting pipe 230, the liquid accumulator 200 is restricted by the welding claws 331 and cannot tilt, which is beneficial to improving the back attachment of the liquid accumulator 200, enhancing the connection stability of the liquid accumulator 200, and reducing the fluctuation of the rotational fixed frequency of the liquid accumulator 200.

[0056] Refer to Figure 7 As shown, the up-and-down direction is defined as the height direction of the compressor housing 110, which is also the height direction of the liquid accumulator housing 210. The upper end face of the connection ring 220 and the welding claw 331 located above the connection ring 220 are fixed by welding, and the welding position is the upper end face of the connection ring 220 and the lower end face of the welding claw 331 located above the connection ring 220; similarly, the lower end face of the connection ring 220 and the welding claw 331 located below the connection ring 220 are fixed by welding, and the welding position is the lower end face of the connection ring 220 and the upper end face of the welding claw 331 located below the connection ring 220. The welding objects in this embodiment are the welding claws 331 and the connection ring 220. The welding of the welding claws 331 to the connection ring 220 realizes the fixation of the bracket 300 and the liquid accumulator 200. On the one hand, it reduces the welding difficulty between the welding claws 331 and the liquid accumulator housing 210, reduces the risk of poor soldering, and also avoids the risk of the liquid accumulator 200 being welded through caused by the direct welding of the inner side surface of the welding claws 331 to the outer wall surface of the liquid accumulator housing 210 in the related art, which is beneficial to improving the defects caused by the welding through of the liquid accumulator 200. On the other hand, it improves the back attachment of the liquid accumulator 200 and improves the fluctuation of the rotational fixed frequency of the liquid accumulator 200.

[0057] Moreover, the compressor in this embodiment overcomes the problem of overconstraint. On the one hand, it realizes constraint decoupling, avoiding manufacturing problems. On the other hand, it ensures the welding strength, keeping the fixed frequency of the liquid accumulator 200 at a high level.

[0058] Refer to Figure 4 and Figure 5As shown, the side of the welding claw 331 facing the liquid storage container housing 210 is an arc surface, and the arc surface is adapted to the outer wall surface of the liquid storage container housing 210. The radius of the arc surface is set to be greater than the radius of the outer wall of the liquid storage container housing 210, which can make the inner wall of the welding claw 331 and the outer wall of the liquid storage container housing 210 fit each other, effectively preventing contact between the two, and ensuring that the liquid storage container 200 can be smoothly assembled into the welding claw 331.

[0059] Referring to Figure 7 As shown, along the height direction of the compressor housing 110 (i.e., Figure 7 the up and down direction hereinafter), the minimum distance between two adjacent welding claws 331 is L1. The minimum distance L1 between the two welding claws 331 is for reserving the installation space for the connecting ring 220. The larger L1 is, the larger the connecting ring 220 is and the higher the welding strength is, but the cost is also higher.

[0060] Along the height direction of the compressor housing 110, the maximum height of the connecting ring 220 along the height direction of the compressor housing 110 is L2, satisfying: 1mm ≤ L1 - L2 ≤ 3mm. The value of L1 - L2 can be 1mm, 2mm, 2.5mm, 3mm, etc. When the above parameter range is satisfied, the welding strength between the connecting ring 220 and the welding claw 331 can be ensured, the connection strength between the liquid storage container 200 and the bracket 300 can be ensured, and at the same time, the assembly of the bracket 300 and the liquid storage container 200 will not be affected. When the value of L1 - L2 is greater than 3mm, the welding strength between the connecting ring 220 and the welding claw 331 cannot meet the requirements. When the value of L1 - L2 is less than 1mm, it is not conducive to the assembly of the liquid storage container 200 and the bracket 300.

[0061] Referring to Figure 7 As shown, the maximum distance that the connecting ring 220 protrudes from the liquid storage container housing 210 is H1, satisfying: H1 ≥ 4mm. The value of H1 can be 4mm, 5mm, 6mm, etc. When the above parameter range is satisfied, the welding strength between the connecting ring 220 and the bracket 300 can be ensured, and at the same time, sufficient margin is left for the gap between the welding claw 331 and the liquid storage container housing 210.

[0062] Referring to Figure 4 and Figure 6As shown in the figure, the bracket 300 of another embodiment of the present utility model further includes a connecting body 340 on the basis of the above embodiment. The connecting body 340 is used to enable the liquid reservoir 200 to better adhere to the back. The connecting body 340 connects two opposite parts of the bracket 300 to form an integral structure, improving the overall strength of the bracket 300. Both sides of the connecting body 340 are fixedly connected to the two wing plates 320 respectively. The connecting body 340 includes two fitting parts 341 arranged at intervals. The two fitting parts 341 respectively abut against the outer wall of the liquid reservoir housing 210 to support the liquid reservoir housing 210. The two fitting parts 341 can increase the lateral restraint on the liquid reservoir 200 and improve the rotational natural frequency of the liquid reservoir 200.

[0063] Referring to Figure 5 As shown in the figure, in an embodiment of the present utility model, the side of the two fitting parts 341 facing the liquid reservoir housing 210 is a plane, which is beneficial to the processing of the fitting parts 341. The plane of the fitting part 341 is tangent to the outer wall of the liquid reservoir housing 210 to realize the back adhesion of the liquid reservoir 200. As an alternative embodiment, the side of the fitting part 341 facing the liquid reservoir housing 210 can also be designed as an arc surface, and the arc surface is adapted to the outer wall surface of the liquid reservoir housing 210, which is beneficial to the better back adhesion of the liquid reservoir 200.

[0064] Referring to Figure 5 As shown in the figure, it can be understood that the connecting body 340 further includes a positioning part 342. The positioning part 342 is located between the two fitting parts 341, and the positioning part 342 abuts against the outer wall of the compressor housing 110. The positioning part 342 is used to position the bracket 300 and the compressor housing 110, facilitating the welding and fixing of the fixing plate 310 and the compressor housing 110. In this embodiment, referring to Figure 6 As shown in the figure, the positioning part 342 is provided with a positioning hole 3422, and the positioning hole 3422 is used to position the compressor housing 110 and the bracket 300.

[0065] Referring to Figure 6 As shown in the figure, in order to improve the overall stability of the bracket 300 and reduce the natural frequency fluctuation of the liquid reservoir 200, the connecting body 340 is symmetrically arranged with respect to the center line M1 of the positioning part 342. Moreover, by arranging the bracket 300 to be symmetrically arranged as a whole with respect to the center line of the positioning part 342, it is beneficial to reduce the stress concentration during the welding process and improve the force conditions among the bracket 300, the liquid reservoir 200 and the compressor main body 100.

[0066] Referring to Figure 5As shown, in one embodiment of the present utility model, in order to enhance the connection strength between the fixing plate 310 and the wing plate 320, the fixing plate 310 and the wing plate 320 are bent at an angle with each other. The connecting line between the connection part of the fixing plate 310 and the wing plate 320 (i.e., the bent part of the two) and the center line of the compressor housing 110 is the first connecting line M2, and the connecting line between the center line of the liquid receiver 200 and the center line of the compressor housing 110 is the second connecting line M3. The included angle between the first connecting line M2 and the second connecting line M3 is α, satisfying: α≥10°, and α can be 10°, 20°, 30°, etc. The fixing plates 310 on the left and the fixing plates 310 on the right also satisfy the above limitations. Meeting the above parameter range can ensure the strength of the bracket 300. If the included angle α is less than 10°, the structure of the bracket 300 will become smaller accordingly, and the overall strength of the bracket 300 will decrease, resulting in the fixed frequency of the liquid receiver 200 being unable to reach a relatively high level.

[0067] Referring to Figure 4 and Figure 5 shown, it can be understood that in order to improve the connection strength between the wing plate 320 and the fixing plate 310, a reinforcing rib 350 is provided between the wing plate 320 and the fixing plate 310. The reinforcing rib 350 is configured to protrude in a direction away from the compressor housing 110 through the connection part of the wing plate 320 and the fixing plate 310. For example, the reinforcing rib 350 is formed by extruding outward at the connection part, which can avoid interference between the reinforcing rib 350 and the installation of the bracket 300 and the compressor housing 110, and the processing is also simpler.

[0068] Referring to Figure 5 shown, the side of the fixing plate 310 facing the compressor housing 110 is an arc surface, and the radius of the arc surface is equal to the radius of the outer wall of the compressor housing 110. Therefore, the fixing plate 310 and the compressor housing 110 can better contact, improving the connection strength between the bracket 300 and the compressor housing 110.

[0069] Referring to Figure 4 and Figure 5 shown, each fixing plate 310 is respectively provided with at least two welding points 311, such as two, three or more. The multiple welding points 311 are arranged at intervals along the height direction of the compressor housing 110, which can improve the connection strength between the bracket 300 and the compressor housing 110.

[0070] Referring to Figure 4 shown, in order to improve the overall strength of the bracket 300, the bracket 300 is an integrally formed part, and the two fixing plates 310, the two wing plates 320, the two welding arms 330 and the connecting body 340 are integrally formed. The material of the bracket 300 can be a metal material such as steel and is made by processes such as stamping and bending.

[0071] A refrigeration device according to an embodiment of the present invention includes the compressor of the above embodiment. The refrigeration device of this embodiment can be a refrigeration device with a compressor such as an air conditioner, a refrigerator, an air source heat pump water heater, a water dispenser, etc. The refrigeration device of this embodiment adopts the compressor of the first aspect embodiment. The compressor is provided with a bracket 300 including two fixing plates 310, two wing plates 320 and two welding arms 330. The liquid receiver 200 includes a connecting ring 220 connected to the outer wall of the liquid receiver housing 210. The two fixing plates 310 are fixedly connected to the outer wall of the compressor housing 110. The two welding arms 330 are respectively connected to the corresponding fixing plates 310 through the wing plates 320. The two welding arms 330 extend in opposite directions. The welding arm 330 includes at least two welding claws 331 spaced along the height direction of the compressor housing 110. The liquid receiver 200 is loaded into the bracket 300 from the opening where the welding arms 330 extend. The welding claws 331 are spaced from the outer wall of the liquid receiver housing 210. The connecting ring 220 is inserted into the gap between two adjacent welding claws 331 and fixedly connected to the upper and lower welding claws 331. Through the matching structure of the connecting ring 220 and the two welding claws 331, the lateral matching gap for fixedly connecting the liquid receiver housing 210 and the welding claws 331 in the related art is changed into the longitudinal matching gap between the connecting ring 220 and the welding claws 331, suppressing the influence of the lateral offset of the connecting pipe 230 on the installation of the liquid receiver 200 and improving the problem of false soldering caused by too large a lateral gap between the welding claws 331 and the liquid receiver housing 210; moreover, it improves the overconstraint situation of the liquid receiver 200 in the rotational direction, strengthens the rotational stiffness of the liquid receiver 200, increases the fixed frequency of the liquid receiver 200, and reduces the low-frequency noise of the compressor. In this embodiment, the positioning of the liquid receiver 200 and the compressor housing 110 is realized through the structure of the connecting ring 220 and the two welding claws 331, so that the liquid receiver 200 cannot be lifted during the welding process of the connecting pipe 230, which is beneficial to improving the liquid receiver 200 against the back.

[0072] Since the refrigeration device according to the embodiment of the present utility model adopts all the technical solutions of the compressor of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated here.

[0073] The above has described in detail the embodiments of the present utility model with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
