Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a sealing structure and an air conditioner. Background Art

[0002] The indoor and outdoor units of the air conditioner are often connected with structures such as refrigerant pipes, drain pipes, and power wires. In order to facilitate the installation of refrigerant pipes, drain pipes, and power wires, they are often integrated through a cluster tube sleeve. The indoor and outdoor unit casings are often provided with mounting holes, and the cluster tubes are passed through the mounting holes. However, this structure often destroys the sealing of the indoor and outdoor unit casings, causing dust, mosquitoes, etc. to easily enter the interior of the indoor and outdoor units from the gap between the mounting holes and the cluster tubes, and when the cluster tubes are twisted, the gap between the pipes and the sealing sleeves will increase. In particular, the outdoor unit, because it is installed outdoors, has higher sealing requirements for dustproof, waterproof, rat-proof, and insect-proof. In the prior art, the sealing structure used is often to set a sealing ring and other structures on the inner periphery of the mounting hole, which has a poor sealing effect and is difficult to meet the sealing requirements.

[0045] The utility model provides a sealing structure 100 for an air conditioner, which includes an air conditioner outdoor unit 200, an air conditioner indoor unit 300, and a flexible connector 22 connecting the air conditioner outdoor unit 200 and the air conditioner indoor unit 300. The casing 21 of the air conditioner outdoor unit 200 or the air conditioner indoor unit 300 is provided with a mounting hole 211 for the flexible connector 22 to pass through.

[0046] See also Figures 1 to 9 In one embodiment of the utility model, the sealing structure 100 includes an installation fixing ring 11 and a sealing fixing structure 12. The outer ring of the installation fixing ring 11 is fixed to the edge of the installation hole 211, and the inner ring of the installation fixing ring 11 is for the flexible connector 22 to pass through; the sealing fixing structure 12 is arranged between the outer periphery of the flexible connector 22 and the inner ring of the installation fixing ring 11, so that the flexible connector 22 and the installation fixing ring 11 are sealed and connected.

[0047] Specifically, see Figure 1The air conditioner includes an outdoor air conditioner 200 and an indoor air conditioner 300. The flexible connector 22 connects the indoor air conditioner 300 and the outdoor air conditioner 200 respectively. The flexible connector 22 can be a flexible refrigerant pipe and a sleeve 221 for housing the flexible refrigerant pipe, a drain pipe and a sleeve 221 for housing the drain pipe, or a power conductor and a sleeve 221 for housing the power conductor. The flexible connector 22 can also include any two of the refrigerant pipe, the drain pipe and the power conductor, and a sleeve 221 for housing the two, or a refrigerant pipe, a drain pipe and a power conductor, and a sleeve 221 for housing the three, for easy connection. A mounting hole 211 is provided on the housing 21 of the outdoor air conditioner 200 or the indoor air conditioner 300. The flexible connector 22 passes through the mounting hole 211 to connect the indoor air conditioner 300 and the outdoor air conditioner 200. However, the sealing requirements of the casing 21 of the air-conditioning outdoor unit 200 or the air-conditioning indoor unit 300 are relatively high. If the sealing structure 100 is not provided between the flexible connector 22 and the mounting hole 211, dust, mosquitoes, mice, etc. may enter the air conditioner through the gap between the mounting hole 211 and the flexible connector 22, which is difficult to clean. Especially for the air-conditioning outdoor unit 200, since it is installed outdoors, the installation environment is more complex and harsh, so the corresponding sealing requirements for dustproof, waterproof, mouse-proof, insect-proof, etc. are higher. If mosquitoes and the like enter the air-conditioning outdoor unit 200 and affect the normal operation of the air-conditioning outdoor unit 200, the user must remove at least part of the casing from the outside to clean it, which is inconvenient to clean. For the convenience of explanation, the following is an example of the sealing structure 100 being provided in the air-conditioning outdoor unit 200.

[0048] In order to ensure the sealing performance of the air conditioner, a sealing fixing structure 12 is provided, and the sealing fixing structure 12 is sleeved on the outer periphery of the flexible connector 22. In order to ensure the fixation of the sealing fixing structure 12, a mounting fixing ring 11 is also provided at the mounting hole 211. The outer ring of the mounting fixing ring 11 is fixed to the edge of the mounting hole 211, and the inner ring of the mounting fixing ring 11 is provided for the flexible connector 22 to pass through. The sealing fixing structure 12 is arranged between the outer periphery of the flexible connector 22 and the inner ring of the mounting fixing ring 11, so that the inner periphery of the sealing fixing structure 12 is sealedly connected to the flexible connector 22, and the outer periphery is sealedly connected to the mounting fixing ring 11, thereby sealing the gap between the mounting hole 211 and the flexible connector 22, and realizing the sealed connection between the flexible connector 22 and the mounting fixing ring 11. Compared with directly providing the sealing fixing structure 12 on the periphery of the mounting hole 211, this solution is convenient for both the opening of the mounting hole 211 and the installation of the sealing fixing structure 12, thereby ensuring both the sealing effect and the installation stability. Furthermore, when the flexible connector 22 is twisted, the sealing fixing structure 12 can twist along with it, so that the gap between the sealing fixing structure 12 and the mounting fixing ring 11 and between the sealing fixing structure 12 and the flexible connector 22 will not increase, thereby further ensuring the sealing effect.

[0049] In order to ensure the sealing effect of the sealing fixing structure 12 and facilitate the installation of the sealing fixing structure 12, the inner periphery of the sealing fixing structure 12 can be directly fixed to the flexible connector 22, and the outer periphery of the corresponding sealing fixing structure 12 is sealed with the inner periphery of the mounting fixing ring 11; or the outer periphery of the sealing fixing structure 12 is directly connected to the inner periphery of the mounting fixing ring 11, and the inner periphery of the corresponding sealing fixing structure 12 is sealed with the outer periphery of the flexible connector 22, that is, one end of the sealing fixing structure 12 is configured as a fixed end and the other end is configured as a free end. Compared with the free ends at both ends of the sealing fixing structure 12, this fixing form is more convenient for the installation of the sealing fixing structure 12, and helps to reduce the number of parts and simplify the sealing structure 100. Of course, in other embodiments, both ends of the sealing fixing structure 12 can also be free ends, that is, the sealing fixing structure 12 is sealed with the mounting fixing ring 11 and the flexible connector 22, respectively.

[0050] When the sealing and fixing structure 12 is actually installed, the installation and fixing ring 11 can be fixed to the installation hole 211 first, and then after the installation of the internal components of the air conditioner outdoor unit 200 is completed, the flexible connector 22 is passed through the inner ring of the installation and fixing ring 11, and after the sealing position of the flexible connector 22 is determined, it is sealed and fixed by the sealing and fixing structure 12. Therefore, preferably, the shape of the inner ring of the installation and fixing ring 11 is adapted to the cross-sectional shape of the flexible connector 22, such as the shapes of the two are roughly the same, and the inner diameter of the inner ring of the installation and fixing ring 11 is slightly larger than the outer diameter of the flexible connector 22, so that it is convenient for the flexible connector 22 to be passed through and the installation of the sealing and fixing structure 12.

[0051] Among them, the sealing structure 100 is at least partially located on the outside of the housing 21, that is, the sealing structure 100 can be completely located on the outside of the housing 21, that is, the mounting ring 11 and the sealing fixing structure 12 are both connected and fixed to the outside of the housing 21; the sealing structure 100 can be partially located on the outside of the housing 21, such as the mounting ring 11 is fixed to the inner side of the mounting hole 211, and the inner ring passes through the mounting hole 211, and the sealing fixing structure 12 is arranged outside the housing 21, or the mounting ring 11 is fixed to the mounting hole 211, one end of the sealing fixing structure 12 passes through the mounting hole 211 and is connected to the mounting ring 11, and the other end extends out of the housing 21, so as to facilitate the fixing of the sealing structure 100. Compared with the sealing structure 100 installed on the inner side of the housing 21, the sealing structure 100 is installed after the installation of the internal components of the air-conditioning outdoor unit 200 is completed in this solution, so that it is not limited by the installation space of the internal components of the air-conditioning outdoor unit 200, and the installation is more convenient.

[0052] See also Figures 2 to 4In an embodiment of the utility model, the sealing fixing structure 12 includes a sealing fixing ring 121, the sealing fixing ring 121 is sealed and sleeved on the flexible connector 22, and the outer periphery of the sealing fixing ring 121 is fixedly connected to the inner ring of the mounting fixing ring 11. Specifically, the sealing fixing ring 121 is often configured as a flexible structure, such as a flexible sealing ring or a flexible sealing sleeve, so that the sealing fixing ring 121 is sleeved on the flexible connector 22, so that the sealing of the two can be achieved, so the sealing fixing ring 121 and the flexible connector 22 often adopt an interference fit. The outer periphery of the sealing fixing ring 121 is fixedly connected to the inner ring of the mounting fixing ring 11, and the sealing fixing ring 121 can be directly connected to the mounting fixing ring 11, such as the sealing fixing ring 121 is directly bonded to the mounting fixing ring 11, or the sealing fixing ring 121 and the inner ring of the mounting fixing ring 11 are interference fit, or the sealing fixing ring 121 and the mounting fixing ring 11 are integrally formed; it can also be indirectly connected to the mounting fixing ring 11, so as to facilitate the assembly of the sealing fixing ring 121.

[0053] When the sealing fixing ring 121 is indirectly connected to the mounting fixing ring 11 , in an embodiment of the utility model, the sealing fixing structure 12 further includes a mounting ring 122 , which is fixedly sleeved on the sealing fixing ring 121 and detachably mounted on the inner ring of the mounting fixing ring 11 . Specifically, the mounting ring 122 is fixedly sleeved on the sealing fixing ring 121, and the mounting ring 122 is fixed to the inner ring of the mounting fixing ring 11, that is, the mounting ring 122 is clamped between the sealing fixing ring 121 and the mounting fixing ring 11 to realize the installation of the sealing fixing ring 121 and the mounting fixing ring 11, and the mounting ring 122 is detachably installed on the inner ring of the mounting fixing ring 11. During actual installation, before assembling the sealing structure 100, the mounting fixing ring 11 can be fixed to the mounting hole 211 first, and the sealing fixing ring 121 and the mounting ring 122 are jointly sleeved on the side of the flexible connector 22 facing the outside of the casing 21. After completing the installation of the internal components of the air-conditioning outdoor unit 200 and determining the sealing position of the flexible connector 22, the mounting ring 122 can be detachably installed on the inner ring of the mounting fixing ring 11, thereby facilitating the assembly of the sealing structure 100. When the sealing position of the flexible connector 22 needs to be adjusted, the mounting ring 122 can be directly detached from the mounting fixing ring 11, thereby facilitating the adjustment of the sealing position of the flexible connector 22. The sealing fixing ring 121 can be bonded to the mounting ring 122, or can be integrally formed with the mounting ring 122.

[0054] Furthermore, a clamping plate 125 extending along the axial direction of the mounting ring 122 is provided on the circumference of the mounting ring 122, and a clamping protrusion 126 facing the mounting fixing ring 11 is provided on the clamping plate 125, and the clamping protrusion 126 is clamped to the inner ring of the mounting fixing ring 11, that is, the mounting ring 122 is clamped to the mounting fixing ring 11, so as to facilitate the disassembly of the mounting ring 122, and compared with the connection using fasteners such as screws, this solution can further reduce the number of parts of the sealing structure 100. The mounting clamping protrusion 126 can be directly clamped to the edge of the inner ring of the mounting fixing ring 11, so that there is no need to set a corresponding clamping part on the inner circumference of the mounting fixing ring 11, thereby facilitating the processing of the mounting fixing ring 11.

[0055] See again Figures 2 to 4 In the embodiment of the utility model, the mounting ring 122 includes a first connection portion 123 and a second connection portion 124 which are bent and connected. The first connection portion 123 extends along the axial direction of the mounting ring 122 and is clamped to the inner ring of the mounting fixing ring 11. The sealing fixing ring 121 is fixed to the first connection portion 123. The second connection portion 124 extends along the radial direction of the mounting ring 122 and is stacked on the outer side of the mounting fixing ring 11. Specifically, the first connection portion 123 extends along the axial direction of the mounting ring 122, so that the first connection portion 123 abuts against the inner ring of the mounting fixing ring 11, which not only facilitates the clamping of the two, but also increases the contact area between the two, reduces the possibility of dust, water, etc. penetrating between the first connection portion 123 and the mounting fixing ring 11, and ensures the sealing of the mounting ring 122 and the mounting fixing ring 11. The second connection portion 124 extends radially along the mounting ring 122 to be overlapped on one side of the mounting fixing ring 11, thereby further blocking the gap between the first connection portion 123 and the mounting fixing ring 11, and further reducing the possibility of dust, water, mosquitoes, etc. penetrating from between the first connection portion 123 and the mounting fixing ring 11. The second connection portion 124 is overlapped on the outside of the mounting fixing ring 11, and the corresponding clamping plate 125 and the clamping protrusion 126 are arranged at one end of the first connection portion 123 away from the second connection portion 124, that is, clamped on the inner side of the mounting fixing ring 11, thereby further facilitating the installation of the mounting ring 122. In other embodiments, the clamping protrusion 126 can also be directly arranged on the first connection portion 123.

[0056] See also Figures 5 to 7In an embodiment of the utility model, the sealing fixing structure 12 is configured as a sealing skirt 127, the first end 128 of the sealing skirt 127 is fixed to the flexible connector 22, the second end 129 extends in a direction away from the first end 128, and the outer diameter of the sealing skirt 127 is enlarged in a direction away from the first end 128, and the inner periphery of the second end 129 is crimped to the outer side of the mounting fixing ring 11. Specifically, the first end 128 of the sealing skirt 127 is fixed to the flexible connector 22, and the second end 129 extends in a direction away from the first end 128, and the outer diameter of the sealing skirt 127 is set to become larger in a direction away from the first end 128, that is, away from the direction along which the flexible connector 22 passes through the housing 21, and the outer diameter of the sealing skirt 127 is set to gradually expand. Therefore, the sealing skirt 127 is configured as an umbrella-shaped structure, and the sealing skirt 127 is a flexible structure, so that the clamping effect of the sealing skirt 127 and the inner ring of the mounting fixing ring 11 is utilized to achieve the sealing of the flexible connector 22 and the mounting ring 122. In the first sealing state (such as the flexible connector 22 is shorter, resulting in tension between the flexible connector 22 and the air-conditioning outdoor unit 200), the inner periphery of the second end 129 is crimped to the outer side of the mounting fixing ring 11, that is, the sealing skirt 127 is sealed to the outer side of the inner ring of the mounting fixing ring 11, thereby ensuring the sealing fixation of the flexible connector 22 and the mounting fixing ring 11, and this sealing form further facilitates the sealing of the sealing structure 100 and reduces the number of components of the sealing structure 100.

[0057] In the direction away from the flexible connector 22 passing through the housing 21, the outer diameter of the sealing skirt 127 is gradually expanded, so that even if the flexible connector 22 has the sealing skirt 127 and passes through the mounting and fixing ring 11, the sealing skirt 127 will not be broken or damaged. Of course, in other embodiments, one end of the sealing skirt 127 can also be fixed to the inner ring of the mounting and fixing ring 11, and the other end can be sealed on the outer periphery of the flexible connector 22.

[0058] See also Figure 5 , Figure 8 and Fig. 9 In another embodiment of the present invention, the sealing fixing structure 12 is provided with a sealing skirt 127, the first end 128 of the sealing skirt 127 is fixed to the flexible connector 22, the second end 129 extends in a direction away from the first end 128, and the outer diameter of the sealing skirt 127 is set to be larger in a direction away from the first end 128, and the inner ring of the mounting fixing ring 11 is clamped on the outer periphery of the second end 129. In the second sealing state (such as the flexible connector 22 is short, so that there is a tension between the flexible connector 22 and the air conditioner indoor unit 300), the inner ring of the mounting fixing ring 11 is clamped on the outer periphery of the second end 129, that is, the sealing skirt 127 is clamped on the inside of the mounting fixing ring 11, thereby ensuring the sealing fixation of the flexible connector 22 and the mounting fixing ring 11.

[0059] Furthermore, the sealing skirt 127 and the flexible connector 22 are integrally formed, thereby ensuring the sealing effect at the connection between the sealing skirt 127 and the flexible connector 22 and reducing the number of parts of the sealing structure 100 .

[0060] In order to facilitate the adjustment of the sealing position of the flexible connector 22, in the embodiment of the utility model, the number of the sealing skirt 127 is multiple, and the multiple sealing skirts 127 are arranged at intervals along the axial direction of the flexible connector 22, and two adjacent sealing skirts 127 are arranged to overlap partially. Specifically, the multiple sealing skirts 127 are arranged at intervals along the axial direction of the flexible connector 22, so that the user can adjust the sealing position of the flexible connector 22 conveniently. In the first sealing state, one of the multiple sealing skirts 127 is crimped to the outer side of the mounting fixing ring 11, and another sealing skirt 127 adjacent to it and close to the second end 129 of the sealing skirt 127 can be clamped with the inner ring of the mounting fixing ring 11; in the second sealing state, at least one of the multiple sealing skirts 127 is clamped to the inner circumference of the mounting fixing ring 11, thereby further improving the sealing strength of the sealing skirt 127. And the distance between the multiple sealing skirts 127 should not be too small, so the two adjacent sealing skirts 127 are arranged to overlap partially.

[0061] In the embodiment of the utility model, a plug-in port 212 is provided on one side of the housing 21, and a lap groove 213 is provided on the edge of the mounting hole 211. The mounting fixing ring 11 is inserted into the housing 21 through the plug-in port 212, and the outer edge of the mounting fixing ring 11 is plugged into the lap groove 213. Specifically, in the embodiment, the mounting hole 211 is provided on the upper cover of the housing 21, and the mounting hole 211 is provided on the edge of the upper cover, so the edge of the upper cover close to the mounting hole 211 has a plug-in port 212, and the mounting fixing ring 11 is inserted into the housing 21 through the plug-in port 212 and is clamped with the edge of the mounting hole 211 facing the inside of the housing 21. In order to fix the mounting fixing ring 11, a lap groove 213 is provided on the inner edge of the mounting hole 211, and the lap groove 213 can be provided on the side away from the plug-in port 212, and the outer edge of the mounting fixing ring 11 is plugged into the lap groove 213, so that the mounting fixing ring 11 is installed on the inner side of the inner housing, which facilitates the installation of the mounting fixing ring 11. Moreover, the overlapping groove 213 can press the outer periphery of the mounting fixing ring 11 to fit the inner periphery of the mounting hole 211, so that the mounting fixing ring 11 is pressed tightly against the housing 21, reducing the possibility of dust, mosquitoes, mice, etc. entering the housing 21, thereby ensuring the sealing performance of the sealing structure 100.

[0062] Furthermore, a clamping hole 214 is formed on one side of the housing 21 away from the plug-in port 212, a first clamping portion 215 is formed on the edge of the plug-in port 212, and a second clamping portion 111 is provided on the mounting ring 11.
