Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a protective cover structure and a compressor using the same. Background Art

[0002] Conventional rotary compressors usually adopt a fully enclosed structure, in which the air intake component 1 is connected to the compressor body 2 through a brass elbow 3 (copper content is not less than 99.9%) and is connected through a connecting part 4 (such as Figure 1 As shown). Although this design realizes the connection function and the communication function in structure, it brings significant defects: the wall thickness of the brass elbow 3 at the connection is relatively thin, usually less than 1.5 mm, which is much lower than the thickness of the compressor body 2 and the thickness of the intake component 1 shell. This wall thickness difference makes the brass elbow 3 connection the weakest part of the compressor outer wall, which makes it easy to be affected by external forces to cause deformation and damage, oil leakage and other problems. Moreover, it is made of copper, which is very easy to be damaged by mechanical pressure or environmental factors.

[0003] In addition, the connection position of the compressor is also a key area for generating noise. Based on the above defects, there is an urgent need for a structure that can not only enhance the structural strength of the entire connection part, but also effectively improve the noise problem of the connection part.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0033] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] Combination Figure 2 As shown, an embodiment of the utility model provides a protective cover structure 10, which is applied to a compressor 20. The compressor 20 includes a compressor body 21 and an air intake assembly 22 connected to the compressor body 21 through a connecting portion 24. A connecting pipe 23 is arranged between the compressor body 21 and the air intake assembly 22. The connecting portion 24 and the connecting pipe 23 are located at different axial positions of the compressor 20. There is a gap between the compressor body 21 and the air intake assembly 22. A covering space is provided in the protective cover structure 10. The connecting pipe 23 is located in the covering space. At least a portion of the protective cover structure 10 is arranged in the gap between the compressor body 21 and the air intake assembly 22.

[0035] In this embodiment, the protective cover structure 10 is designed with a covering space inside to accommodate the connecting pipe 23. At least a part of the protective cover structure 10 is arranged in the gap between the compressor body 21 and the air intake assembly 22, so that the protective cover structure 10 not only covers the connecting pipe 23, but also part of the protective cover structure 10 enters the gap, which helps the protective cover structure 10 to provide additional support when the compressor 20 is running, and reduces the shaking of the air intake assembly 22 caused by the vibration of the compressor 20. By arranging the protective cover structure 10 on the air intake assembly 22 and the connecting pipe 23, the bottom reinforcement point of the air intake assembly 22 is increased by the protective cover structure 10, and the vibration displacement of the air intake assembly 22 when the compressor 20 is working can be effectively reduced. The protective cover structure 10 covers the weakest brass elbow of the compressor 20 (i.e., the connecting pipe 23) and provides enhanced protection to prevent deformation and damage, oil leakage, etc. caused by external forces at this place, thereby reducing the compressor elimination rate. At the same time, the protective cover structure 10 covers the entire connecting pipe 23 by covering the space, thereby improving the noise feedback at the bottom of the air intake component 22 and the connecting pipe 23, and reducing the noise generated by the compressor.

[0036] Specifically, the connecting portion 24 is located between the compressor body 21 and the air intake assembly 22. The design of the connecting portion 24 takes into account the axial layout of the compressor 20 and is located at a different position from the connecting pipe 23. For example, the connecting portion 24 is located at the top and the connecting pipe 23 is located at the bottom. Figure 2 As shown, the connection portion 24 is located at the upper part of the gap between the compressor body 21 and the intake assembly 22, and the protective cover structure 10 is located at the lower part of the gap between the compressor body 21 and the intake assembly 22. The connection portion 24 applies a rightward force to the intake assembly 22, and the protective cover structure 10 applies a leftward force to the intake assembly 22. The rightward force and the leftward force offset each other, which can provide a more optimized mechanical structure and reduce the transmission of vibration. This allows the connection portion 24 to more effectively disperse and absorb vibration when subjected to dynamic loads during operation, thereby reducing the mechanical stress on the connecting pipe 23.

[0037] For example, assuming that in an air conditioning system, the compressor 20 operates under a relatively high load, by installing the protective cover structure 10 provided by the utility model on the compressor 20, when facing external environmental factors (such as temperature changes, mechanical shocks, etc.), the stability of the connecting pipe 23 can be more effectively maintained, and the mechanical stress on the connecting pipe 23 can be reduced. The protective cover structure 10 is usually detachably connected to the compressor 20, which is convenient for replacement and maintenance.

[0038] In one embodiment, a sound absorbing layer and / or a heat insulating layer is disposed in the covering space of the protective cover structure 10 .

[0039] In this embodiment, the protective cover structure 10 is further improved by providing a sound-absorbing layer and / or a heat-insulating layer to enhance its noise control and heat-insulating performance. The protective cover structure 10 is not only used to protect the connection part of the compressor 20, but also a sound-absorbing layer or a heat-insulating layer can be designed inside the covering space of the protective cover structure 10. Of course, a sound-absorbing layer and a heat-insulating layer can also be provided at the same time. The sound-absorbing layer is mainly composed of sound-insulating cotton, and the heat-insulating layer is mainly composed of heat-insulating rubber. The sound-absorbing layer and the heat-insulating layer are fixed to the inner wall of the protective cover structure 10. As a sound-absorbing material, the sound-insulating cotton can reduce the propagation of noise generated by the operation of the compressor 20, while the heat-insulating rubber helps to cut off heat conduction, thereby preventing the deformation of the compressor 20 structure caused by temperature changes. It is recommended that the inner wall radius of the protective cover structure 10 is larger than the outer wall radius of the connecting pipe 23, for example, a space of 1-2 mm is reserved, and the reserved space can be used to set the sound-absorbing layer and / or the heat-insulating layer.

[0040] In one embodiment, at least a portion of the protective cover structure 10 covers the air intake assembly 22 .

[0041] In this embodiment, if Figure 2As shown, the protective cover structure 10 covers the connecting pipe 23 and also covers the lower end of the air intake assembly 22. The connecting portion 24 is arranged between the upper end of the air intake assembly 22 and the compressor body 21. At this time, the force direction of the upper end of the air intake assembly 22 is Figure 2 As shown by the right arrow in the middle. Under the action of the protective cover structure 10, the force direction of the lower end of the air intake component 22 is Figure 2 As shown by the left arrow in the middle. That is, the force direction of the upper end of the air intake assembly 22 is opposite to the force direction of the lower end of the air intake assembly 22, which improves the vibration balance effect of the air intake assembly 22, so that the noise generated by the air intake assembly 22 during operation is greatly reduced. In this embodiment, the protective cover structure 10 has two openings, one opening is set at the top, and the other opening is set at the side. The opening at the top is used to avoid the lower end of the air intake assembly 22, and the opening at the side is used to avoid one end of the connecting pipe 23 connected to the compressor body 21.

[0042] Combination Figures 3 to 5 As shown, in one embodiment, the air intake assembly 22 is located in the covering space.

[0043] In this embodiment, the main purpose of the protective cover structure 10 is to provide an external protective layer for the air intake assembly 22, that is, on the basis of protecting the connecting pipe 23 connecting the compressor body 21 and the air intake assembly 22, it also protects the entire air intake assembly 22. Figure 3 As shown, the protective cover structure 10 is set to a fully wrapped state, that is, fully wrapped air intake assembly 22. The air intake assembly 22 is completely located in the covered space, and the protective cover structure 10 can also reduce the impact of mechanical vibration transmitted to the air intake assembly 22. Similarly, after the protective cover structure 10 fully wraps the air intake assembly 22, a sound-absorbing layer and / or a heat-insulating layer can also be set on the corresponding inner wall. Of course, the top of the protective cover structure 10 can also be set with an opening, and the pipeline on the top of the air intake assembly 22 can extend from the opening.

[0044] In one embodiment, the protective cover structure 10 is provided with an annular reinforcement portion 11 , and the annular reinforcement portion 11 is surrounded by the outer side of the air intake assembly 22 .

[0045] In the present embodiment, the annular reinforcement portion 11 mainly functions to enclose and reinforce the outer side of the air intake assembly 22. The annular reinforcement portion 11 is generally designed as an annular structure surrounding the outer side of the air intake assembly 22. By arranging the annular reinforcement portion 11 at the outermost side of the air intake assembly 22, it is possible to effectively resist potential damage caused by external factors (such as mechanical impact or vibration) and protect the air intake assembly 22 from deformation or damage. The annular reinforcement portion 11 is generally made of a high-strength material (such as steel or a high-strength alloy) to ensure that it can maintain its shape when subjected to higher loads. In the case where the protective cover structure 10 fully wraps the air intake assembly 22, a plurality of annular reinforcement portions 11 may be arranged at intervals in the axial direction of the compressor, such as Figure 3There are three corresponding annular reinforcement parts 11 in the structure, which respectively reinforce the upper, middle and lower parts of the air intake assembly 22.

[0046] In one embodiment, the lower end surface of the annular reinforcement portion 11 is not lower than the lower end surface of the air intake assembly 22 .

[0047] In this embodiment, when installing the protective cover structure 10, the interaction with the compressor body 21 and the air intake assembly 22 is taken into consideration. The protective cover structure 10 not only wraps the connecting pipe 23, but also has an annular reinforcement portion 11 designed on its structure to provide additional structural support.

[0048] The design of the annular reinforcement portion 11 ensures that the lowest point of the protective cover structure 10 in the longitudinal direction is not lower than the lower end surface of the air intake assembly 22. This is to ensure that the upper part of the protective cover structure 10 can be fully locked at both ends of the compressor body 21 and the air intake assembly 22, and to make the connection between the compressor body 21 and the air intake assembly 22 more stable, thereby enhancing the force balance of the protective cover structure 10.

[0049] Combination Figure 6 As shown, in one embodiment, the protective cover structure 10 includes a first covering portion 12 and a second covering portion 13, which are covered and connected to form the covering space, and one or both of the first covering portion 12 and the second covering portion 13 are arranged in the gap between the compressor body 21 and the intake assembly 22.

[0050] In this embodiment, in addition to being integrally formed, the protective cover structure 10 can also be provided in a combined form. That is, the protective cover structure 10 includes a first covering portion 12 and a second covering portion 13, and these two parts work together to enhance the overall performance of the compressor 20. The first covering portion 12 and the second covering portion 13 are covered with each other by a specific connection method (such as screw connection) to form the covering space, and the purpose of this covering space is to accommodate and protect the connecting pipe 23 between the compressor body 21 and the air intake assembly 22, while providing additional sound insulation and heat insulation effects. One or both of the first covering portion 12 and the second covering portion 13 are usually arranged in the gap between the compressor body 21 and the air intake assembly 22, and can provide protection for vibration between the air intake assembly 22 and the compressor body 21, for example Figure 6 The first cover part 12 and the second cover part 13 are partially disposed together in the gap between the compressor body 21 and the air intake assembly 22. The first cover part 12 and the second cover part 13 can be made of a variety of materials, including but not limited to metal, synthetic materials or composite materials. The material of the protective cover structure 10 is usually PET engineering plastic, and other materials can also be selected according to actual conditions, which is not limited here.

[0051] Furthermore, the protective cover structure 10 can increase the bottom reinforcement point of the air intake component 22, reduce the vibration displacement of the bottom of the air intake component 22 when the compressor body 21 is working, and can also improve the noise of the bottom of the air intake component 22 and the connecting pipe 23, and enhance the protection of the connecting pipe 23. The outer wall of the air intake component 22 and the inner wall of the protective cover structure 10 are in an interference state, so that the structural connection between the two is more stable. For example, the inner wall of the protective cover structure 10 is set to be equal to or less than 0.5 mm of the outer diameter of the air intake component 22 (it can also be other values).

[0052] Combination Figure 7 As shown, in one embodiment, the first covering portion 12 and the second covering portion 13 are connected by a connecting piece, and the connecting piece is disposed at a position close to but not in contact with the connecting pipe 23 .

[0053] In this embodiment, the connecting member is usually a screw, and the mounting screw of the protective cover structure 10 is designed with a one-way screw on one side (corresponding to the second covering part 13) and a screw column 121 with a built-in thread on the other side (corresponding to the first covering part 12). The position of the screw column 121 inside the protective cover structure 10 needs to be as close to the connecting pipe 23 as possible, but it needs to maintain a certain distance to reduce vibration transmission, thereby improving noise and vibration control. In addition, the diameter of the screw and the screw hole is usually selected to be smaller than the shortest straight-line distance between the air intake component 22 and the compressor body 21 to facilitate installation. Further, multiple screw holes can be set at different positions of the protective cover structure 10, and these screw holes correspond to multiple screws, and the multiple screws are used to be firmly installed on the protective cover structure 10 to lock the protective cover structure 10 to the air intake component 22. The advantage of using multiple screws is that multiple screws can provide a stronger locking force, and can maintain stability even when the compressor 20 generates large vibrations during operation.

[0054] Combination Figure 8 As shown, in one embodiment, two sides of at least a portion of the protective cover structure 10 are in contact with the compressor body 21 and the air intake assembly 22 respectively.

[0055] In this embodiment, by increasing the tightening torque of the connecting member, both sides of at least a portion of the protective cover structure 10 are in contact with both sides of the compressor body 21 and the intake assembly 22 (eg, Figure 8 As shown), the cover structure 10 is strengthened to fasten the air intake assembly 22. Figure 8 As an example, the two sides of the protective cover structure 10 are squeezed toward the middle from the upper and lower directions, and the forces generated by the two sides of the protective cover structure 10 (i.e. Figure 8 The upper and lower arrows of the Figure 8 As shown by the left and right arrows, the protective cover structure 10 generates a force on the intake assembly 22 that moves away from the compressor body 21.

[0056] The utility model also provides a compressor 20, including a compressor body 21 and an air intake assembly 22, a connecting pipe 23 is arranged between the compressor body 21 and the air intake assembly 22, and a gap is provided between the compressor body 21 and the air intake assembly 22, and the compressor 20 also includes the protective cover structure 10 as described above.

[0057] In this embodiment, there is a certain gap between the compressor body 21 and the air intake assembly 22, which can provide space for the installation of the protective cover structure 10. The protective cover structure 10 effectively increases the anti-environmental impact capability of the compressor 20 by reducing the external exposure of the connecting pipe 23 and the air intake assembly 22, and can also reduce noise and heat loss through the sound insulation and heat insulation materials inside the protective cover structure 10.

[0058] Combination Fig. 9 As shown, the protective cover structure 10 in the present invention plays the role of a clamp, especially at the connection part between the air intake assembly 22 and the compressor body 21, that is, the connection pipe 23. In addition, by comparing the vibration test of the existing compressor without a clamp and the compressor with a clamp, as shown in FIG. Fig. 9 According to the test results presented in , the 2nd frequency displacement of the existing compressor without clamp blocks is significantly higher than the 2nd frequency displacement of the compressor with clamp blocks. Therefore, the protective cover structure 10 of the utility model can effectively slow down the vibration displacement and reduce the noise; this not only prolongs the service life of the compressor 20, but also improves its performance in a high-demand environment.

[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
