Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air conditioning, and in particular to a heat exchanger assembly and an air conditioner. Background Art
[0002] Air conditioners are essential appliances in our daily lives, available in a wide variety of structural forms. With the continuous advancement of industrial design and the application of new processes, materials, and designs, not only have a wide variety of air conditioner styles been developed, but the structures themselves have also been optimized accordingly.
[0003] In the prior art, the grounding structure of the heat exchanger of the air conditioner is often to fix the grounding wire directly to the side plate of the heat exchanger through fasteners such as screws. This places high demands on the disassembly and assembly of the grounding structure in actual production and life. This is not only not conducive to improving the disassembly and assembly efficiency of the grounding structure, resulting in low production efficiency and disassembly and maintenance efficiency of the air conditioner, but also easily causes scratches to human hands.
[0004] In addition, although the prior art also has a method of connecting the grounding wire to the heat exchanger structure to achieve grounding of the heat exchanger, it is often difficult to ensure the reliability of the connection between the grounding wire and the heat exchanger structure, and the grounding wire is easily separated from the heat exchanger structure, resulting in grounding failure.
[0005] At the same time, whether the grounding wire is fixed with screws or connected to the heat exchanger structure, during the disassembly and assembly of the heat exchanger, especially during the later maintenance process, people often directly touch the metal connector of the grounding wire to perform operations, which is not only prone to static electricity interference, but also easy to cause scratches to people's hands during the disassembly and assembly of the grounding wire. Summary of the Invention
[0006] In view of this, the present invention aims to propose a heat exchanger assembly and an air conditioner to solve the problems in the prior art of low efficiency in disassembly and assembly of the heat exchanger grounding wire and easy scratches on human hands during disassembly and assembly of the grounding wire.
[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:
[0008] A heat exchanger assembly includes a heat exchanger and a grounding assembly. The refrigerant pipeline of the heat exchanger is provided with a plug. The grounding assembly includes a grounding plug, a protective shell, and a grounding cable. An assembly space is provided in the protective shell. The grounding plug is arranged in the assembly space in a snap-on manner. One end of the grounding plug is plugged into the plug, and the other end of the grounding plug is connected to the grounding cable. Therefore, by plugging the grounding assembly with the plug, the more cumbersome assembly method in the prior art is avoided, which is conducive to improving the disassembly and assembly efficiency of the grounding structure. In addition, by additionally providing a protective shell, on the one hand, when people disassemble and assemble the grounding structure, their hands will not directly touch the metal grounding connector. Instead, they can touch the protective shell and apply force to the protective shell to achieve the plugging and unplugging between the grounding assembly and the plug, which can directly eliminate the risk of metal parts scratching people's hands. On the other hand, the protective shell can effectively protect the grounding plug, and can to a certain extent prevent foreign objects from contacting the grounding plug.
[0009] Furthermore, the protective shell includes a hollow shell, and a first limit member and a second limit member are provided on the inner side wall of the shell. The first limit member is engaged and limited with the grounding plug in the insertion direction of the grounding component, and the second limit member is engaged and limited with the grounding plug in the removal direction of the grounding component; thereby, whether the grounding component is inserted or removed, the protective shell can be firmly assembled with the grounding plug to avoid separation between the protective shell and the grounding plug, effectively preventing the outside world from disassembling the protective shell and the grounding plug, and providing long-lasting and effective protection for the plugging and unplugging operations of the grounding component and even the grounding plug.
[0010] Furthermore, the grounding plug includes a main body, and snap-fitting curled edges are provided on both sides of the main body, forming a snap-fitting cavity between the snap-fitting curled edge and the main body. The snap-fitting cavity is snap-fitted to the plug-in piece, which not only facilitates the plug-in between the grounding component and the plug-in piece, but also helps to improve the disassembly and assembly efficiency of the grounding structure, and also facilitates the processing and production of the grounding plug.
[0011] Furthermore, a limiting space is formed between the first limiting member and the inner side wall, and the snap-fitting edge is arranged in the limiting space. The snap-fitting edge abuts against the first limiting member in the insertion direction of the grounding component, thereby enabling the first limiting member to simply and conveniently limit the grounding plug in the insertion direction of the grounding component.
[0012] The main body of the grounding plug is provided with a limiting boss at one end close to the grounding cable, and the limiting boss abuts against the second limiting member in the removal direction of the grounding assembly, thereby enabling the second limiting member and the grounding plug to be easily and conveniently engaged and limited.
[0013] The second limiting member is provided with an abutment plate on the side facing the limiting boss, and the abutment plate abuts against the limiting boss. Relatively speaking, the abutment plate occupies a smaller space, thereby ensuring the effectiveness of the abutment between the limiting boss and the second limiting member on the one hand, and avoiding the second limiting member from occupying too much space and causing unnecessary spatial interference on the other hand.
[0014] Furthermore, the plug includes a fixed plate and a plug-in plate. The fixed plate is fixedly connected to the refrigerant pipeline. One end of the plug-in plate is connected to the fixed plate, and the other end extends away from the refrigerant pipeline. The plug-in plate is provided with a latching hole, and the main body is provided with a protrusion on the side facing the latching cavity. The protrusion engages with the latching hole, thereby improving the connection between the ground plug and the plug.
[0015] The protective shell is integrally formed, which is not only convenient for processing and production, but also helps to ensure the mechanical strength of the protective shell.
[0016] An air conditioner comprises the heat exchanger assembly described above.
[0017] Compared with the prior art, the heat exchanger assembly and air conditioner described in the present invention have the following advantages:
[0018] The heat exchanger assembly and air conditioner described in the present invention avoid the complicated assembly method in the prior art by plugging the grounding assembly into the plug, which is beneficial to improving the efficiency of disassembly and assembly of the grounding structure.
[0019] At the same time, by additionally providing a protective shell, on the one hand, people will not directly touch the metal grounding connector with their hands when disassembling and assembling the grounding structure. Instead, they can plug and unplug the grounding component and the plug by touching the protective shell and applying force to the protective shell, which can directly eliminate the risk of metal parts scratching people's hands. On the other hand, the protective shell can effectively protect the grounding plug and can prevent foreign objects from contacting the grounding plug to a certain extent.

[0029] The inventive concepts of the present disclosure will be described below using terms commonly used by those skilled in the art to convey the essence of their work to other persons skilled in the art. However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.
[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0031] In the prior art, the grounding structure of the heat exchanger of the air conditioner is often to fix the grounding wire directly to the side plate of the heat exchanger through fasteners such as screws. This places high demands on the disassembly and assembly of the grounding structure in actual production and life. This is not only not conducive to improving the disassembly and assembly efficiency of the grounding structure, resulting in low production efficiency and disassembly and maintenance efficiency of the air conditioner, but also easily causes scratches to human hands.
[0032] In order to solve the problem of low efficiency in disassembly and assembly of the grounding structure of the heat exchanger in the prior art and easy scratching of the hands during disassembly and assembly of the grounding structure, this embodiment proposes a heat exchanger assembly, as shown in the attached Figure 1-6As shown, the heat exchanger assembly includes a heat exchanger 1 and a grounding assembly 2. The refrigerant pipeline 11 of the heat exchanger 1 is provided with a plug 12. The grounding assembly 2 includes a grounding plug 3, a protective shell 4, and a grounding cable 5. An assembly space 46 is provided in the protective shell 4. The grounding plug 3 is arranged in the assembly space 46 in a snap-fit manner. One end of the grounding plug 3 is plugged into the plug 12, and the other end of the grounding plug 3 is connected to the grounding cable 5 to achieve grounding of the refrigerant pipeline 11 and the heat exchanger 1.
[0033] Therefore, the present application avoids the cumbersome assembly method in the prior art by plugging the grounding component 2 with the plug 12, which is conducive to improving the efficiency of disassembly and assembly of the grounding structure. In addition, by additionally providing a protective shell 4, on the one hand, when people disassemble and assemble the grounding structure, their hands will not directly touch the metal grounding connector (corresponding to the grounding plug 3 of the present application), but instead they can touch and apply force to the protective shell 4 to achieve the plugging and unplugging of the grounding component 2 and the plug 12, which can directly eliminate the risk of metal parts scratching people's hands. On the other hand, the protective shell 4 can effectively protect the grounding plug 3 and can prevent foreign objects from contacting the grounding plug 3 to a certain extent. At the same time, the material of the protective shell 4 is preferably plastic, with insulating plastic and anti-static plastic being the best, so that when the human hand touches the protective shell 4, the generation of static electricity can be effectively avoided, eliminating the interference of static electricity.
[0034] The heat exchanger 1 can be a conventional heat exchanger in an indoor unit or outdoor unit of an air conditioner, and its structure can directly adopt existing technology, which will not be described in detail here. The refrigerant pipeline 11 can be a conventional pipeline of the heat exchanger 1, and can also be preferably a liquid inlet pipe or liquid outlet pipe of the heat exchanger 1. The plug 12 includes a fixed plate 121 and a plug-in plate 122. The fixed plate 121 is fixedly connected to the refrigerant pipeline 11. Preferably, the plug 12 is welded to the refrigerant pipeline 11 through the fixed plate 121. One end of the plug-in plate 122 is connected to the fixed plate 121, and the other end extends in a direction away from the refrigerant pipeline 11 to facilitate the plug-in connection between the plug 12 and the grounding plug 3.
[0035] The grounding plug 3 includes a main body 31, with snap-fitting edges 32 provided on both sides of the main body 31. A snap-fitting cavity 33 is formed between the snap-fitting edge 32 and the main body 31. The snap-fitting cavity 33 snaps into the insert 12, thereby facilitating the connection between the grounding component 2 and the insert 12, thereby improving the efficiency of the assembly and disassembly of the grounding structure, and facilitating the processing and production of the grounding plug 3.
[0036] In order to further enhance the connection between the grounding plug 3 and the insert 12 and improve the assembly reliability of the grounding assembly 2, the plug board 122 is provided with a latching hole 123, and the main board body 31 is provided with a protrusion 34 on a side facing the latching cavity 33. When the grounding assembly 2 and the insert 12 are plugged in, the protrusion 34 engages with the latching hole 123, thereby enhancing the connection reliability between the grounding plug 3 and the insert 12. Preferably, the protrusion 34 is a hemispherical protrusion, so that when the grounding assembly 2 and the insert 12 are plugged in, the operator does not need to apply excessive force, and the protrusion 34 can smoothly engage with the latching hole 123, which helps to reduce the difficulty of assembly and disassembly.
[0037] On this basis, in order to facilitate the description of direction-related content, this application takes the two end faces of the protective shell 4 as the reference, the first end face 47 of the protective shell 4 is the end close to the plug 12, and the second end face 48 of the protective shell 4 is the end close to the grounding cable 5 (that is, the end away from the plug 12); since the plug 12 is in a relatively static state with the heat exchanger 1, the direction of inserting the grounding component 2 into the plug 12 can be regarded as the direction from the second end face 48 to the first end face 47 (uniformly referred to as "insertion direction" in this application), and the direction of pulling out the grounding component 2 can be regarded as the direction from the first end face 47 to the second end face 48 (uniformly referred to as "pulling out direction" in this application).
[0038] Regarding the assembly of the grounding plug 3 and the protective shell 4, the protective shell 4 includes a hollow shell 41, the inner cavity of the shell 41 being the assembly space 46, and the inner side wall 42 of the shell 41 being provided with a first limiting member 43 and a second limiting member 45. The first limiting member 43 clamps and limits the grounding plug 3 in the insertion direction of the grounding component 2, and the second limiting member 45 clamps and limits the grounding plug 3 in the removal direction of the grounding component 2. At the same time, in a plane perpendicular to the insertion direction (or removal direction) of the grounding component 2, the shell 41 surrounds and encloses the grounding plug 3, so that the protective shell 4 can be firmly assembled with the grounding plug 3 regardless of whether the grounding component 2 is inserted or removed, thereby preventing the protective shell 4 from being separated from the grounding plug 3, effectively preventing the protective shell 4 and the grounding plug 3 from being disassembled by the outside world, and providing long-lasting and effective protection for the plugging and unplugging operations of the grounding component 2 and even the grounding plug 3.
[0039] As for the relevant limiting structure of the first limiting member 43, one end of the first limiting member 43 is connected to the inner wall 42, and the other end extends in a direction away from the inner wall 42 and at the same time close to the first end face 47, so that a limiting space 44 is formed between the first limiting member 43 and the inner wall 42, and the snap-fitting edge 32 is arranged in the limiting space 44, and the snap-fitting edge 32 abuts against the first limiting member 43 in the insertion direction of the grounding component 2, or in other words, the snap-fitting edge 32 abuts against the first limiting member 43 at its end facing the grounding cable 5. At the same time, not only the snap-fitting edge 32 is arranged in the limiting space 44, but the first limiting member 43 can also be regarded as being arranged in the snap-fitting cavity 33, so that in the insertion direction of the grounding component 2, the snap-fitting limiting of the grounding plug 3 by the first limiting member 43 can be simply and conveniently achieved.
[0040] As for the related limiting structure of the second limiting member 45, the second limiting member 45 is a protruding structure on the inner side wall 42, which can be as shown in the attached figure. Figure 2 As shown in FIG, the housing 41 is recessed into the assembly space 46 to form a convex structure, which can also be as shown in FIG. Figure 4 As shown, the housing 41 is provided with a protrusion directly on the inner sidewall 42. The main body 31 of the grounding plug 3 is provided with a limiting boss 35 at one end near the grounding cable 5. The limiting boss 35 abuts against the second limiting member 45 in the direction of removal of the grounding assembly 2, thereby enabling simple and convenient engagement and limiting of the second limiting member 45 with the grounding plug 3. Considering the considerable length of the grounding plug 3 and its retaining edge 32, to avoid spatial interference, the second limiting member 45 is provided with an abutment plate 49 on the side facing the limiting boss 35. The abutment plate 49 abuts against the limiting boss 35, and the space occupied by the abutment plate 49 is relatively small. This ensures effective engagement between the limiting boss 35 and the second limiting member 45 while preventing the second limiting member 45 from occupying too much space and causing unnecessary spatial interference. Preferably, the abutment plate 49 is connected to the second limiting member 45 and the inner side wall 42 at the same time. In the direction from the first end face 47 to the second end face 48, the cross-sectional area of the abutment plate 49 gradually decreases, so that appropriate space avoidance can be performed during the assembly process of the grounding plug 3 and the protective shell 4.
[0041] Based on the related limiting structures of the first limiting member 43 and the second limiting member 45, an anti-disassembly component is automatically formed between the grounding plug 3 and the protective shell 4 of the present application, making it difficult to disassemble and separate the grounding plug 3 and the protective shell 4 after assembly, so that the protective shell 4 can provide long-lasting and effective protection for the plugging and unplugging operations of the grounding component 2 and even the grounding plug 3. Specifically, based on the structure of the above-mentioned first limiting member 43, the first limiting member 43 extends obliquely to form a structure similar to an inclined guide rail. During assembly, the snap-fitting edge 32 is slid along the first limiting member 43 in the insertion direction until the snap-fitting edge 32 completely slides past the first limiting member 43 toward one end of the grounding cable 5, so that the snap-fitting edge 32 falls entirely into the limiting space 44. The grounding plug 3 is then moved in the removal direction so that the snap-fitting edge 32 gradually abuts against the second limiting member 45 in the limiting space 44. At the same time, the grounding plug 3 also approaches the inner side wall 42. Accordingly, the distance between the limiting boss 35 and the inner side wall 42 becomes increasingly closer until the limiting boss 35 abuts against the second limiting member 45. At this point, the grounding plug 3 and the protective shell 4 are simultaneously limited by the related limiting structures of the first limiting member 43 and the second limiting member 45, which also makes the grounding plug 3 and the protective shell 4 easier and more convenient to assemble.
[0042] The protective shell 4 is preferably integrally injection molded, which is not only convenient for processing and production, but also helps to ensure the mechanical strength of the protective shell 4. The grounding cable 5 is a conventional wire connected to the grounding component of the air conditioner or directly grounded. Since the connection and grounding of the grounding cable of the air conditioner can adopt existing technologies, they are not described in detail here.
[0043] In the present invention, any air-conditioning indoor unit or outdoor unit may include the heat exchanger assembly described in this embodiment, and based on the relevant structure and assembly relationship of the heat exchanger assembly provided in this embodiment, the air-conditioning also includes an air-conditioning indoor unit including components such as an air guide structure and an electrical control structure, and conventional components of an air-conditioning outdoor unit including structures such as a fan and a compressor; since they are all existing technologies, they will not be described in detail here.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
