Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor and air-conditioning equipment. Background Art

[0002] Scroll compressors are widely used in refrigeration, air conditioning, heat pumps and other fields due to their high efficiency, small size, low noise and vibration, light weight, and stable operation. Generally speaking, scroll compressors are used in air-conditioning systems and need to be installed and fixed as operating components. Usually, a structure that is installed in conjunction with the chassis of the air-conditioning system needs to be set at the lower end of the compressor. This structure generally needs to be welded to the lower cover of the compressor and then connected to the bottom plate of the air-conditioning system to complete the installation and fixation.

[0003] For example, the current common fixed installation method is to weld an additional base at the lower end of the compressor, and connect the base to the vibration-damping support on the chassis of the air-conditioning system with bolts and other fasteners to achieve fixed installation of the compressor. However, this installation method requires more parts, a more complex structure, and more process steps, resulting in higher production costs. In addition, since the compressor is fixed by fasteners such as bolts, there is a risk of the bolts loosening under the influence of vibration during the operation of the compressor, which can easily lead to increased vibration and noise. At the same time, in the current installation method, the vibration-damping supports are distributed on the periphery of the compressor, and the distance from the center of gravity of the compressor is large, which does not provide good support for the compressor under vibration conditions. Utility Model Content

[0004] In order to solve the problems of the existing compressor installation method, such as the large number of parts, poor reliability and poor supporting effect under vibration conditions, the utility model proposes a compressor and air-conditioning equipment.

[0005] In the first aspect, the utility model proposes a compressor, which includes a main body and a lower cover, wherein the lower cover is arranged at one end of the main body, and at least one assembly groove is constructed on the bottom surface of the lower cover, and the assembly groove extends along the axial direction of the main body, and the assembly groove is used to at least partially accommodate a vibration-damping support that matches the compressor.

[0006] In one embodiment, the assembly groove includes a first groove body and a second groove body which are arranged in sequence along the axial direction of the main body, and the second groove body is constructed at the groove bottom of the first groove body; wherein, the first groove body is used to accommodate the vibration-damping rubber pad of the vibration-damping support, and the second groove body is used to accommodate the end of the pillar of the vibration-damping support, and the end of the pillar protrudes from the vibration-damping rubber pad.

[0007] In one embodiment, the second groove body has a smaller dimension in the radial direction of the main body than the first groove body.

[0008] In one embodiment, the internal space of the second groove is configured as a cylinder, and an internal thread is formed on the side wall of the second groove for mating with an external thread formed at the end of the support column.

[0009] In one embodiment, the lower cover includes opposite first and second ends. The first end is used to connect to the main body of the compressor, the bottom surface is formed on the end surface of the second end, and the dimension of the second end in the radial direction of the compressor is greater than that of the first end.

[0010] In one embodiment, the lower cover includes a cylindrical body portion and a bottom plate portion. The cylindrical body portion is used to connect to the main body of the compressor, and the bottom surface is formed on the bottom plate portion. Wherein, the cylindrical body portion and the bottom plate portion are integrally formed, or the cylindrical body portion and the bottom plate portion are formed separately and connected by welding.

[0011] In one embodiment, the part of the lower cover forming the assembly groove protrudes towards the inner direction of the main body relative to the top surface of the lower cover, and the top surface is the other surface opposite to the bottom surface.

[0012] In one embodiment, the number of the assembly grooves is multiple, and the multiple assembly grooves are evenly distributed on the bottom surface of the lower cover.

[0013] In a second aspect, an air conditioning device provided by the present invention includes:

[0014] The compressor described above; and

[0015] A support assembly, which includes a mounting base plate and a vibration damping support provided on the mounting base plate. The vibration damping support includes a vibration damping rubber pad;

[0016] Wherein, the vibration damping rubber pad is fitted in the assembly groove on the bottom surface of the compressor. Under the pressure of the gravity of the compressor, the vibration damping rubber pad expands in the direction perpendicular to the gravity and tightly fits with the side wall of the assembly groove.

[0017] In one embodiment, both ends of the vibration damping rubber pad respectively abut against the mounting base plate and the bottom of the assembly groove. The vibration damping rubber pad is partially accommodated in the assembly groove, and there is a gap between the bottom surface of the compressor and the mounting base plate.

[0018] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the object of the present invention can be achieved.

[0019] A compressor and an air conditioning device provided by the present invention, compared with the prior art, at least have the following beneficial effects:

[0020] A compressor and an air-conditioning device of the present utility model, based on the improved design of the compressor structure, reduce the number of components required for compressor installation and simplify the compressor structure. Based on the simplified structure, the technological steps are also simplified; the use of fasteners such as bolts and nuts is eliminated, avoiding the risk of loosening of the fasteners under vibration conditions; the vibration damping support can be directly matched directly below the compressor, greatly reducing the degree of misalignment with the center of gravity of the compressor, improving the stability of the installation structure under the vibration conditions of the compressor, and at the same time reducing the floor area of the compressor installation structure and improving the compactness of the structure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The present utility model will be further described below in conjunction with the accompanying drawings.

[0033] Embodiment 1

[0034] An embodiment of the present utility model provides a compressor, which includes a main body 1 and a lower cover 2. The lower cover 2 is disposed at one end of the main body 1. At least one assembly groove 3 is formed on the bottom surface of the lower cover 2. The assembly groove 3 extends along the axial direction of the main body 1 and is used to at least partially accommodate a vibration damping support 41 that cooperates with the compressor.

[0035] Specifically, as shown in the accompanying drawings Figure 1 As shown, the compressor in this embodiment is a vertical compressor. The general installation method of a vertical compressor is as shown in the accompanying drawings Figure 7 As shown, that is, a skirt base (skirt-type base) is welded on the outer wall of the lower end of the compressor. A plurality of support positions are provided at the edge of the skirt base. The plurality of support positions are distributed around the lower end of the compressor. Each support position cooperates with the corresponding support and is supported by the support, and then the support is further fixed to the skirt base by bolts. As can be seen from the accompanying drawings Figure 7 The deficiencies of the currently adopted installation structure include, but are not limited to: (1) There are more components. For the compressor, a skirt base and corresponding bolt fasteners need to be equipped, the structure is relatively complex, and there is a risk of loosening of the fasteners; (2) Due to more components, its production process steps are more, and the production cost is higher; (3) The centers of gravity of the support and the compressor are offset in the horizontal direction, and the vibration of the compressor (especially the vibration in the vertical direction) will exert a bending moment on the skirt base, which is not conducive to the structural stability; (4) The setting of the skirt base and its support positions thereon results in a relatively large floor area of the compressor installation structure, which is not conducive to the application in small equipment.

[0036] Aiming at the defects of the above existing installation structure, this embodiment optimizes the structure of the vertical compressor (specifically a vertical scroll compressor in this embodiment), mainly by optimizing the structure of the lower cover 2 of the compressor, so as to change the existing installation method. As shown in the accompanying drawings Figure 1 As shown, the present utility model forms an assembly groove 3 on the bottom surface of the lower cover 2 of the compressor (that is, the bottom surface of the whole compressor). The assembly groove 3 is recessed towards the inside of the compressor main body 1 relative to the bottom surface of the lower cover 2, so that the assembly groove 3 can accommodate the corresponding vibration damping support 41. As shown in the accompanying drawings Figure 5 As shown, when the compressor is installed, the compressor is directly placed on the vibration damping support 41, and at least part of the vibration damping support 41 is embedded in the assembly groove 3 and fills the assembly groove 3. Compared with the existing installation structure shown in the accompanying drawings Figure 7 As shown, based on the accompanying drawings Figure 1The shown compressor can achieve a brand-new installation method, and its advantages include: (1) fewer components, eliminating the skirt base and corresponding bolt fasteners, simplifying the structure to avoid the risk of fastener loosening; (2) based on the structural simplification, the process steps can also be correspondingly simplified; (3) the vibration damping support 41 is directly arranged right below the compressor, with a greatly reduced offset from or direct alignment with the center of gravity of the compressor, which can improve the stability of the installation structure under the vibration condition of the compressor; (4) the vibration damping support 41 is embedded in the bottom of the compressor, greatly reducing the floor area of the compressor installation structure and improving the compactness of the structure and the neatness of the appearance.

[0037] It should be noted that the present utility model mainly further designs the structure of the lower cover 2 of the compressor, so as to provide a structural basis for the new installation method. The structures of other parts of the compressor are not the main inventive points of the present utility model, and their specific structures can refer to the existing scroll compressors, which will not be elaborated herein.

[0038] Preferably, the part of the lower cover 2 forming the assembly groove 3 protrudes towards the inside of the main body 1 relative to the top surface of the lower cover 2, and the top surface is the other surface opposite to the bottom surface. As shown in the attached drawing Figure 1 For the vertical compressor of the present utility model shown, the lower cover 2 corresponds to the oil sump inside the compressor main body 1. In this embodiment, the part of the lower cover 2 corresponding to the assembly groove 3 is recessed towards the oil sump inside the main body 1 relative to the top surface of the lower cover 2, that is, it protrudes from the top surface of the lower cover 2, so that the contact area between the lower cover 2 and the lubricating oil in the oil sump is larger, which is conducive to the lubricating oil dissipating heat outward through the lower cover 2, thereby assisting in the cooling of the lubricating oil. Optionally, the assembly groove 3 is formed on the lower cover 2 by stamping process.

[0039] Preferably, the number of the assembly grooves 3 is multiple, and the multiple assembly grooves 3 are evenly distributed on the bottom surface of the lower cover 2. As shown in the attached drawing Figure 3 For the shown structure, the number of the assembly grooves 3 is multiple, which can cooperate with multiple vibration damping supports 41 to further improve the stability of the compressor installation. The multiple assembly grooves 3 are evenly distributed, and the specific distribution structure can be an annular array layout or a rectangular integral layout with the center of the bottom surface of the lower cover 2 as the distribution center.

[0040] Furthermore, the lower cover 2 includes an opposite first end and second end. The first end is used to connect the main body 1 of the compressor, the bottom surface is constructed on the end surface of the second end, and the dimension of the second end in the radial direction of the compressor is larger than that of the first end.

[0041] Specifically, in the attached drawing Figure 1As shown in the figure, the lower cover 2 includes a first end and a second end. The first end of the lower cover 2 is an open structure for connecting to the main body 1 of the compressor; the second end of the lower cover 2 is a closed structure, that is, a closed end face is formed, and this end face serves as the bottom surface. That is to say, the diameter of the bottom surface of the lower cover 2 is larger than the diameter of the open mouth at its first end. Since the open mouth is used to connect to the main body 1 of the compressor, it means that the diameter of the bottom surface of the lower cover 2 is larger than the diameter of the main body 1 of the compressor.

[0042] With such a design, from the perspective of the structure of the compressor itself, the increase in the diameter of the lower cover 2 can improve the stability of the compressor itself; in addition, from the perspective of the installation of the compressor, a larger bottom surface area can be provided with more assembly grooves 3, or in other words, the distribution of multiple assembly grooves 3 on the bottom surface can be more flexible, which can improve the stability of the compressor after installation.

[0043] Embodiment 2

[0044] An embodiment of the present utility model provides a compressor, which includes a main body 1 and a lower cover 2. The lower cover 2 is arranged at one end of the main body 1. At least one assembly groove 3 is formed on the bottom surface of the lower cover 2. The assembly groove 3 extends along the axial direction of the main body 1, and the assembly groove 3 is used to at least partially accommodate a vibration damping support 41 that cooperates with the compressor.

[0045] Specifically, as shown in the attached drawings Figure 1 As shown, the compressor in this embodiment is a vertical compressor. The general installation method of a vertical compressor is as shown in the attached drawings Figure 7 As shown, that is, a skirt base (skirt type base) is welded on the outer wall at the lower end of the compressor. A plurality of support positions are arranged at the edge of the skirt base. The plurality of support positions are distributed around the lower end of the compressor. Each support position cooperates with the corresponding support and is supported by the support, and then the support is further fixed to the skirt base by bolts. According to the attached drawings Figure 7 It can be seen that the deficiencies of the currently adopted installation structure include but are not limited to: (1) There are more parts. For the compressor, a skirt base and corresponding bolt fasteners need to be equipped, the structure is relatively complex, and there is a risk of loosening of the fasteners; (2) Due to more parts, its production process steps are more, and the production cost is higher; (3) The centers of gravity of the support and the compressor are offset in the horizontal direction, and the vibration of the compressor (especially the vibration in the vertical direction) will exert a bending moment on the skirt base, which is not conducive to the stability of the structure; (4) The setting of the skirt base and its support positions thereon results in a relatively large floor area for the installation structure of the compressor, which is not conducive to application in small equipment.

[0046] Aiming at the defects of the above existing installation structure, in this embodiment, the structure of the vertical compressor (specifically, a vertical scroll compressor in this embodiment) is optimized, mainly by optimizing the structure of the lower cover 2 of the compressor, so as to change the existing installation method. As shown in the attached drawings Figure 1As shown, the utility model is provided with a mounting groove 3 on the bottom surface of the lower cover 2 of the compressor (that is, the bottom surface of the entire compressor), and the mounting groove 3 is recessed toward the inside of the compressor body 1 relative to the bottom surface of the lower cover 2, so that the mounting groove 3 can accommodate the corresponding vibration reduction support 41. Figure 5 As shown, when the compressor is installed, the compressor is directly placed on the vibration-damping support 41, and the vibration-damping support 41 is at least partially embedded in the assembly groove 3 and fills the assembly groove 3. Compared with the accompanying drawings Figure 7 The existing installation structure shown in the accompanying drawings Figure 1 The compressor shown in the figure can realize a completely new installation method, and its advantages include: (1) fewer parts, eliminating the skirt seat and the corresponding bolt fasteners, simplifying the structure to avoid the risk of fasteners loosening; (2) based on the simplification of the structure, the process steps can also be simplified accordingly; (3) the vibration-damping support 41 is directly arranged under the compressor, and the center of gravity of the compressor or the degree of misalignment with the center of gravity of the compressor is greatly reduced, which can improve the stability of the installation structure under the vibration condition of the compressor; (4) the vibration-damping support 41 is embedded in the bottom of the compressor, which greatly reduces the footprint of the compressor installation structure and improves the compactness of the structure and the neatness of the appearance.

[0047] It should be noted that the utility model is mainly aimed at further designing the structure of the lower cover 2 of the compressor, so as to provide a structural basis for a new installation method. The structure of other parts of the compressor is not the main invention point of the utility model. Its specific structure can refer to the existing vortex compressor, and the utility model will not go into details.

[0048] Preferably, the portion of the lower cover 2 forming the assembly groove 3 protrudes toward the inside of the main body 1 relative to the top surface of the lower cover 2, and the top surface is the other side surface relative to the bottom surface. Figure 1 As shown, in the vertical compressor of the utility model, the lower cover 2 corresponds to the oil pool inside the compressor body 1. In this embodiment, the portion of the lower cover 2 corresponding to the assembly groove 3 is relatively recessed toward the oil pool inside the body 1, that is, protruding from the top surface of the lower cover 2, so that the contact area between the lower cover 2 and the lubricating oil in the oil pool is larger, which is conducive to the heat dissipation of the lubricating oil to the outside through the lower cover 2, thereby assisting the cooling of the lubricating oil. Optionally, the assembly groove 3 is formed on the lower cover 2 by a stamping process.

[0049] Preferably, there are multiple assembly grooves 3, and the multiple assembly grooves 3 are evenly distributed on the bottom surface of the lower cover 2. Figure 3 As shown, there are multiple assembly slots 3, which can be matched with multiple vibration-damping supports 41 to further improve the stability of compressor installation. Multiple assembly slots 3 are evenly distributed, and the specific distribution structure can be a ring array layout or a rectangular array layout with the center of the bottom surface of the lower cover 2 as the distribution center.

[0050] Further, the lower cover 2 includes an opposite first end and a second end. The first end is used to connect to the main body 1 of the compressor. The bottom surface is formed on the end surface of the second end. The size of the second end in the radial direction of the compressor is larger than that of the first end.

[0051] Specifically, as shown in the attached drawings Figure 1 The lower cover 2 includes a first end and a second end. The first end of the lower cover 2 is an open structure for connecting to the main body 1 of the compressor; the second end of the lower cover 2 is a closed structure, that is, a closed end surface is formed, and this end surface serves as the bottom surface. That is to say, the diameter of the bottom surface of the lower cover 2 is larger than the diameter of the open mouth at its first end. Since the open mouth is used to connect to the main body 1 of the compressor, it means that the diameter of the bottom surface of the lower cover 2 is larger than the diameter of the main body 1 of the compressor.

[0052] In such a design, from the perspective of the structure of the compressor itself, the increase in the diameter of the lower cover 2 can improve the stability of the compressor itself; in addition, from the perspective of the installation of the compressor, a larger bottom surface area can be provided with more assembly grooves 3, or multiple assembly grooves 3 can be distributed more flexibly on the bottom surface, which can improve the stability after the compressor is installed.

[0053] Further, the assembly groove 3 includes a first groove body 31 and a second groove body 32 arranged in sequence along the axial direction of the main body 1. The second groove body 32 is formed on the groove bottom of the first groove body 31; wherein, the first groove body 31 is used to accommodate the damping rubber pad 411 of the damping support 41, and the second groove body 32 is used to accommodate the end of the column 412 of the damping support 41, and the end of the column 412 protrudes from the damping rubber pad 411.

[0054] Specifically, as shown in the attached drawings Figure 1 and Figure 2 shown, the assembly groove 3 includes a first groove body 31 and a second groove body 32 in part in the depth direction, that is, the first groove body 31 is directly formed on the bottom surface of the lower cover 2, and the second groove body 32 is directly formed on the groove bottom of the first groove body 31. The size of the second groove body 32 in the radial direction of the main body 1 is preferably smaller than that of the first groove body 31. With such a structural design of the assembly groove 3, the purpose is to cooperate with the corresponding damping support 41 to improve the installation stability. Specifically, the general structure of the damping support 41 is as shown in the attached drawings Figure 5 shown, that is, a damping rubber pad 411 is provided on a column 412, and the top end of the column 412 protrudes from the top of the rubber pad body. The relatively protruding end of the column 412 is used to cooperate with the corresponding nut fastener in the existing installation method. In this embodiment, the first groove body 31 is used to cooperate with the damping rubber pad 411, and the second groove body 32 is used to cooperate with the top end of the column 412, so as to adapt to the conventional damping support 41 and improve the versatility of the compressor in this embodiment during installation.

[0055] In addition, the first tank 31 and the second tank 32 have different focuses during installation. The first tank 31 is matched with the damping rubber pad 411 of the flexible structure, mainly used to achieve the damping of the compressor. The second tank 32 is matched with the top end of the rigid support column 412, mainly used to achieve the installation limit of the compressor.

[0056] Further, the internal space structure of the second tank 32 is cylindrical, and an internal thread is formed on the side wall of the second tank 32, which is used to cooperate with the external thread formed at the end of the support column 412.

[0057] Specifically, based on the structural design of the second tank 32, its internal space is further structured as a cylinder and an internal thread is provided. In this way, at least an external thread is provided at the end of the support column 412 of the damping support 41 to achieve the threaded connection between the damping support 41 and the assembly groove 3, further increasing the constraint on the compressor and improving the stability. In addition, during installation, the support column 412 of the damping support 41 and the corresponding installation base plate 42 also adopt threaded cooperation (the support column 412 is a stud), so that the end of the support column 412 can be screwed into the second tank 32.

[0058] Embodiment 3

[0059] An embodiment of the present utility model provides a compressor, which includes a main body 1 and a lower cover 2. The lower cover 2 is arranged at one end of the main body 1, and at least one assembly groove 3 is formed on the bottom surface of the lower cover 2. The assembly groove 3 extends along the axial direction of the main body 1 and is used to at least partially accommodate the damping support 41 that cooperates with the compressor.

[0060] Specifically, as shown in the attached drawings Figure 1 In the embodiment, the compressor is a vertical compressor. The general installation method of a vertical compressor is as shown in the attached drawings Figure 7 That is, a skirt seat (skirt base) is welded on the outer wall at the lower end of the compressor. A plurality of support positions are arranged at the edge of the skirt seat, and the plurality of support positions are distributed around the lower end of the compressor. Each support position is matched with the corresponding support and supported by the support, and then the support and the skirt seat are further fixed by bolts. As can be seen from the attached drawings Figure 7 The deficiencies of the currently adopted installation structure include but are not limited to: (1) There are many components. For the compressor, a skirt seat and corresponding bolt fasteners need to be equipped, the structure is relatively complex, and there is a risk of loosening of the fasteners; (2) Due to the large number of components, its production process steps are more, and the production cost is higher; (3) The centers of gravity of the support and the compressor are offset in the horizontal direction, and the vibration of the compressor (especially the vibration in the vertical direction) will exert a bending moment on the skirt seat, which is not conducive to the stability of the structure; (4) The arrangement of the skirt seat and the support positions thereon results in a large floor area of the compressor installation structure part, which is not conducive to the application in small equipment.

[0061] In view of the defects of the above existing installation structure, in this embodiment, the structure of a vertical compressor (specifically, a vertical scroll compressor in this embodiment) is optimized, mainly by optimizing the structure of the lower cover 2 of the compressor, so as to change the existing installation method. As shown in the attached drawings Figure 1 As shown, in the present utility model, an assembly groove 3 is formed on the bottom surface of the lower cover 2 of the compressor (that is, the bottom surface of the whole compressor). The assembly groove 3 is recessed towards the inside of the compressor main body 1 relative to the bottom surface of the lower cover 2, so that the assembly groove 3 can accommodate the corresponding vibration damping support 41. As shown in the attached drawings Figure 5 As shown, when the compressor is installed, the compressor is directly placed on the vibration damping support 41, and at least part of the vibration damping support 41 is embedded in the assembly groove 3 and fills the assembly groove 3. Compared with the existing installation structure shown in the attached drawings Figure 7 As shown, based on the compressor shown in the attached drawings Figure 1 As shown, it can achieve a new installation method, and its advantages include: (1) fewer components, eliminating the skirt base and corresponding bolt fasteners, simplifying the structure to avoid the risk of loosening of the fasteners; (2) based on the simplification of the structure, the process steps can also be correspondingly simplified; (3) the vibration damping support 41 is directly arranged directly below the compressor, and the alignment with the center of gravity of the compressor or the degree of offset from the center of gravity of the compressor is greatly reduced, which can improve the stability of the installation structure under the vibration condition of the compressor; (4) the vibration damping support 41 is embedded in the bottom of the compressor, greatly reducing the floor area of the compressor installation structure, and improving the compactness of the structure and the neatness of the appearance.

[0062] It should be noted that the present utility model mainly further designs the structure of the lower cover 2 of the compressor, so as to provide a structural basis for the new installation method. The structures of other parts of the compressor are not the main inventive points of the present utility model, and their specific structures can refer to the existing scroll compressors, which will not be elaborated herein.

[0063] Preferably, the part of the lower cover 2 forming the assembly groove 3 protrudes towards the inside of the main body 1 relative to the top surface of the lower cover 2, and the top surface is the other surface opposite to the bottom surface. As shown in the attached drawings Figure 1 As shown, for the vertical compressor of the present utility model, the part of the lower cover 2 corresponds to the oil sump inside the compressor main body 1. In this embodiment, the part of the lower cover 2 corresponding to the assembly groove 3 is recessed towards the oil sump inside the main body 1, that is, protruding from the top surface of the lower cover 2, so that the contact area between the lower cover 2 and the lubricating oil in the oil sump is larger, which is beneficial to the heat dissipation of the lubricating oil through the lower cover 2, thereby assisting in the cooling of the lubricating oil. Optionally, the assembly groove 3 is formed on the lower cover 2 by stamping process.

[0064] Preferably, the number of the assembly grooves 3 is multiple, and the multiple assembly grooves 3 are evenly distributed on the bottom surface of the lower cover 2. As shown in the attached drawings Figure 3As shown, the number of the assembly grooves 3 is multiple, so that multiple vibration damping supports 41 can be matched, further improving the stability of the compressor installation. The multiple assembly grooves 3 are evenly distributed, and the specific distribution structure can be an annular array layout or a rectangular alignment layout with the center of the bottom surface of the lower cover 2 as the distribution center.

[0065] Furthermore, the lower cover 2 includes an opposite first end and a second end. The first end is used to connect the main body 1 of the compressor, the bottom surface is constructed on the end surface of the second end, and the size of the second end in the radial direction of the compressor is larger than that of the first end.

[0066] Specifically, in the attached drawing Figure 1 As shown, the lower cover 2 includes a first end and a second end. The first end of the lower cover 2 is an open structure for connecting with the main body 1 of the compressor; the second end of the lower cover 2 is a closed structure, that is, a closed end surface is formed, and this end surface serves as the bottom surface. That is to say, the diameter of the bottom surface of the lower cover 2 is larger than the diameter of the open mouth of its first end. Since the open mouth is used to connect the main body 1 of the compressor, that is, the diameter of the bottom surface of the lower cover 2 is larger than the diameter of the main body 1 of the compressor.

[0067] In such a design, from the perspective of the structure of the compressor itself, the increase in the diameter of the lower cover 2 can improve the stability of the compressor itself; in addition, from the perspective of the installation of the compressor, a larger bottom surface area can be provided with more assembly grooves 3, or in other words, the multiple assembly grooves 3 can be more flexibly distributed on the bottom surface, which can improve the stability after the compressor is installed.

[0068] Furthermore, the assembly groove 3 includes a first groove body 31 and a second groove body 32 that are sequentially arranged along the axial direction of the main body 1. The second groove body 32 is constructed on the groove bottom of the first groove body 31; wherein, the first groove body 31 is used to accommodate the damping rubber pad 411 of the vibration damping support 41, and the second groove body 32 is used to accommodate the end of the support column 412 of the vibration damping support 41, and the end of the support column 412 protrudes from the damping rubber pad 411.

[0069] Specifically, as shown in the attached drawing Figure 1 and Figure 2 As shown, the assembly groove 3 includes a first groove body 31 and a second groove body 32 that are partially arranged in the depth direction, that is, the first groove body 31 is directly constructed on the bottom surface of the lower cover 2, and the second groove body 32 is directly constructed on the groove bottom of the first groove body 31. The size of the second groove body 32 in the radial direction of the main body 1 is preferably smaller than that of the first groove body 31. With such a structural design of the assembly groove 3, the purpose is to cooperate with the corresponding vibration damping support 41 to improve the installation stability. Specifically, the general structure of the vibration damping support 41 is as shown in the attached drawing Figure 5As shown, a vibration damping rubber pad 411 is provided on a support column 412. The top end of the support column 412 protrudes above the top of the rubber pad body. The relatively protruding end of the support column 412 is used to cooperate with a corresponding nut fastener in the existing installation method. In this embodiment, the first groove 31 is used to cooperate with the vibration damping rubber pad 411, and the second groove 32 is used to cooperate with the top end of the support column 412, so as to be able to adapt to a conventional vibration damping support 41 and improve the versatility of the compressor in this embodiment during installation.

[0070] In addition, the first groove 31 and the second groove 32 have different focuses during installation. The first groove 31 cooperates with the flexible vibration damping rubber pad 411 and is mainly used to achieve vibration damping of the compressor. The second groove 32 cooperates with the top end of the rigid support column 412 and is mainly used to achieve installation limit of the compressor.

[0071] Furthermore, the internal space of the second groove 32 is configured as a cylinder, and internal threads are formed on the side wall of the second groove 32 for cooperating with the external threads formed at the end of the support column 412.

[0072] Specifically, based on the structural design of the second groove 32, its internal space is further configured as a cylinder and internal threads are provided. In this way, at least external threads are provided at the end of the support column 412 of the vibration damping support 41 to achieve threaded connection between the vibration damping support 41 and the assembly groove 3, further increasing the constraint on the compressor and improving stability. In addition, during installation, the support column 412 of the vibration damping support 41 and the corresponding installation base plate 42 also adopt threaded cooperation (the support column 412 is a stud), so that the end of the support column 412 can be screwed into the second groove 32.

[0073] Furthermore, the lower cover 2 includes a cylindrical body part 21 and a bottom plate part 22. The cylindrical body part 21 is used to connect the main body 1 of the compressor, and the bottom surface is formed on the bottom plate part 22. Among them, the cylindrical body part 21 and the bottom plate part 22 are integrally formed, or the cylindrical body part 21 and the bottom plate part 22 are formed separately and connected by welding.

[0074] Specifically, the lower cover 2 as a whole includes a cylindrical body part 21 and a bottom plate part 22. The lower surface of the bottom plate part 22 serves as the bottom surface of the lower cover 2. One end of the cylindrical body part 21 is used to connect the main body 1 of the compressor and the other end is connected to the bottom plate part 22. According to process requirements, the cylindrical body part 21 and the bottom plate part 22 of the lower cover 2 can have two structures as a whole: (1) As shown in the attached drawings Figures 1 to 3 shown, the cylindrical body part 21 and the bottom plate part 22 are integrally formed. The cylindrical body part 21 and the bottom plate part 22 of the lower cover 2 are directly integrally formed from a plate. The cylindrical body part 21 has a reduced-diameter section, and then the assembly groove 3 is punched on the bottom plate part 22; The installation state of the compressor with the integrally structured lower cover 2 is as shown in the attached drawings Figure 5As shown in the figure. (2) The cylindrical part 21 and the bottom plate part 22 are separately prepared and formed. There is a reduced-diameter section in the cylindrical part 21. Then, an assembly groove 3 is punched on the bottom plate part 22. Finally, the cylindrical part 21 and the bottom plate part 22 are welded. In this structure, the diameter of the bottom plate part 22 is slightly larger than the large end of the cylindrical part 21, so that the edge of the bottom plate part 22 extends beyond the cylindrical part 21 to leave space for welding. The installation state of the compressor with the split lower cover 2 is shown in the attached drawing Figure 6 as shown.

[0075] Embodiment 4

[0076] An embodiment of the present utility model provides an air-conditioning device, which includes the compressor of any one of the above embodiments and a support assembly 4. The support assembly 4 includes a mounting base plate 42 and a vibration damping support 41 provided on the mounting base plate 42. The vibration damping support 41 includes a vibration damping rubber pad 411. Among them, the vibration damping rubber pad 411 is fitted in the assembly groove 3 on the bottom surface of the compressor. Under the pressure of the gravity of the compressor, the vibration damping rubber pad 411 expands in the direction perpendicular to the gravity and closely fits with the side wall of the assembly groove 3.

[0077] Further, both ends of the vibration damping rubber pad 411 respectively abut against the mounting base plate 42 and the bottom of the assembly groove 3. The vibration damping rubber pad 411 is partially accommodated in the assembly groove 3, and there is a gap between the bottom surface of the compressor and the mounting base plate 42.

[0078] Specifically, as shown in the attached drawing Figure 5 and Figure 6 as shown, the support assembly 4 includes a mounting base plate 42 and a vibration damping support 41 provided on the mounting base plate 42. The vibration damping support 41 includes a pillar 412 connected to the mounting base plate 42 and a vibration damping rubber pad 411 sleeved on the pillar 412. In the assembly structure of the compressor and the support assembly 4, the upper part of the vibration damping rubber pad 411 is embedded in the assembly groove 3 on the bottom surface of the compressor, specifically, it is embedded in the first groove body 31 of the assembly groove 3, and the top end of the pillar 412 is embedded in the second groove body 32 of the assembly groove 3. In the assembled state, one end of the vibration damping rubber pad 411 abuts against the bottom of the first groove body 31 and the other end abuts against the mounting base plate 42. Under the action of the gravity of the compressor, the vibration damping rubber pad 411 is flattened and expands in volume in the direction perpendicular to the gravity, and then completely fills the first groove body 31 and closely fits with the side wall of the first groove body 31. Therefore, both the side wall and the bottom of the first groove body 31 are in close contact with the vibration damping rubber pad 411, so that the vibration of the compressor in the vertical and horizontal directions can be buffered, and on the one hand, the positioning of the compressor and the support assembly 4 in the vertical and horizontal directions is realized.

[0079] In addition, there is a gap between the bottom surface of the compressor and the mounting base plate 42, so that the compressor is entirely supported by the vibration damping supports 41. The gravity of the compressor fully acts on the vibration damping rubber pads 411, avoiding rigid contact with the mounting base plate 42 or other structures, which enables the vibration damping rubber pads 411 to give full play to their vibration damping effect.
