[0065] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0066] The following is for reference. Figures 1-15 This invention describes an air conditioner 100 according to an embodiment of the present invention. The air conditioner 100 of this embodiment can be an integrated air conditioner or a split-type air conditioner. When the air conditioner 100 of this embodiment is a split-type air conditioner, the air conditioner 100 may include a separately configured indoor unit and an outdoor unit.

[0067] like Figure 1 As shown, the air conditioner 100 according to an embodiment of the present utility model includes: a housing 10, a valve island 21, a shut-off valve 66, and a connecting bracket 40.

[0068] Specifically, the housing 10 is provided with structural support members; the valve island 21 has multiple channels for refrigerant flow, and the shut-off valve 66 is connected to the valve island 21; the valve island 21 is fixedly connected to the structural support members through the connecting bracket 40.

[0069] Structural support components refer to structural components on or within the housing 10 that serve to install and support other components located within the housing 10. For example, structural support components can be the top plate, chassis 13, front side plate, left side plate, or right side plate of the housing 10. Other examples include the heat exchanger side plate 12, the electrical control box mounting plate 15, and the fan mounting bracket.

[0070] Valve island 21 is configured to integrate multiple control valves, such as the electronic expansion valve 61, four-way valve 62, and one-way solenoid valve 64 of the air conditioner 100. Multiple channels are formed within valve island 21; these channels can be independent of each other, interconnected, or partially interconnected while others remain independent. Valve island 21 also has multiple valve island interfaces 211, with each channel connected to at least two interfaces 211. Valve island 21 connects to multiple control valves via these interfaces 211. It also connects to a plate heat exchanger 63 for enthalpy enhancement via these interfaces, and further connects to a gas-liquid separator 30, an oil-liquid separator 65, and a compressor 50 via these interfaces. Thus, valve island 21 connects multiple control valves, gas-liquid separator 30, plate heat exchanger 63, and compressor 50 in series via multiple interfaces, forming the refrigerant flow path of the air conditioner 100.

[0071] In this embodiment, the valve island 21, multiple control valves, gas-liquid separator 30, and plate heat exchanger 63 can be pre-assembled and welded together. After pre-assembly and welding, leak detection can be performed on the integrated module of the valve island 21, multiple control valves, gas-liquid separator 30, and plate heat exchanger 63. This reduces the number of weld points during the final assembly of the air conditioner 100, thereby reducing the leakage rate during final assembly and improving assembly efficiency. Furthermore, since multiple control valves, gas-liquid separator 30, and plate heat exchanger 63 can be connected through the valve island 21, the length of the piping can be reduced, mitigating the problems of increased pipe resistance and pressure drop caused by excessively long piping.

[0072] The shut-off valve 66 is connected to the valve island 21. Specifically, the shut-off valve 66 can be directly connected to the valve island 21, or it can be indirectly connected to the valve island 21 via a connecting pipe, so that the shut-off valve 66 communicates with the channel within the valve island 21. Alternatively, the shut-off valve 66 can be directly mounted and fixed to the valve island 21, or it can be indirectly mounted and fixed to the valve island 21 via other support structures (such as the valve plate 22 described below) or pipelines, or it can be mounted and fixed to other components of the air conditioner 100 via other support structures.

[0073] There can be one or two shut-off valves 66. For example, there are two shut-off valves 66, namely a high-pressure shut-off valve and a low-pressure shut-off valve. Both the high-pressure shut-off valve and the low-pressure shut-off valve are connected to the indoor heat exchanger through refrigerant pipelines.

[0074] Furthermore, the valve island 21 is fixedly connected to the structural support member via the connecting bracket 40. For example, the valve island 21 and the connecting bracket 40 can be welded, bolted, snapped, and / or riveted. The connecting bracket 40 and the structural support member can also be connected by welding, bolting, snapping, and / or riveting.

[0075] According to the embodiment of the present utility model, in the air conditioner 100, the valve island 21 is fixedly connected to the structural support through the connecting bracket 40, which can improve the reliability of the fixed connection of the valve island 21. When vibration is transmitted to the valve island 21, it can also reduce the problem of the valve island 21 shaking due to vibration, ensure the connection reliability and sealing performance between the valve island 21 and the control valve and other components in the air conditioner 100, and improve the installation reliability of the valve island 21.

[0076] In some embodiments of this utility model, the air conditioner 100 further includes a gas-liquid separator 30, which is disposed within the housing 10, and a valve island 21 is fixedly connected to the gas-liquid separator 30. In other words, the valve island 21 is fixedly supported on the gas-liquid separator 30.

[0077] In some examples, the valve island 21 can be directly fixed to the gas-liquid separator 30. For instance, the valve island 21 can be fixed to the gas-liquid separator 30 by welding, or by bolts. Alternatively, the valve island 21 and the gas-liquid separator 30 can be riveted, snap-fitted, or adhesively bonded. In other examples, the valve island 21 can be fixed to the gas-liquid separator 30 by a fixing bracket. The valve island 21 and the fixing bracket can be welded, bolted, snap-fitted, and / or riveted, and the fixing bracket and the gas-liquid separator 30 can be welded, bolted, snap-fitted, and / or riveted. In still other examples, the valve island 21 can also be fixed to the gas-liquid separator 30 by a pipe support. Specifically, the valve island 21 and the gas-liquid separator 30 are connected by a connecting pipe, and the valve island 21 is fixedly supported on the gas-liquid separator 30 by the connecting pipe.

[0078] Since the valve island 21 is fixedly connected to the structural support through the connecting bracket 40, and in this embodiment, the valve island 21 is also fixedly connected to the gas-liquid separator 30, the valve island 21 can be fixedly connected to multiple structural components, thereby further improving the reliability of fixing the valve island 21 and further reducing the problem of the valve island 21 shaking due to vibration.

[0079] In some embodiments of this utility model, such as Figure 4As shown, the air conditioner 100 also includes multiple refrigerant control devices configured to control the on / off state, flow regulation, flow direction switching, and refrigerant heat exchange of the refrigerant in the refrigerant circuit. The multiple refrigerant control devices include at least one of the following: an electronic expansion valve 61, a four-way valve 62, a plate heat exchanger 63, a one-way solenoid valve 64, an oil separator 65, and a gas-liquid separator 30.

[0080] Furthermore, multiple valve island interfaces 211 are formed on the valve island 21, and each channel connects to at least two valve island interfaces 211. The valve island 21 is connected to the shut-off valve 66 and multiple refrigerant control devices through the multiple valve island interfaces 211.

[0081] In this embodiment, the valve island 21 connects to multiple refrigerant control devices and shut-off valves 66 through multiple valve island interfaces 211. The valve island 21 can be pre-assembled and welded with multiple refrigerant control devices. After pre-assembly and welding, the pre-assembled and welded integrated module can be leak-tested. This reduces the number of solder joints in the air conditioner 100 during final assembly, thereby reducing the leakage rate of final assembly welding, improving the assembly efficiency of final assembly, and reducing the length of the pipeline, thus reducing the problems of increased pipe resistance and reduced pressure caused by excessively long pipelines.

[0082] In some examples, multiple valve island interfaces 211 can be all located on the upper side of the valve island 21, or all located on the lower side of the valve island 21. Alternatively, some valve island interfaces 211 can be formed on the upper side of the valve island 21, while others are formed on the lower side. This allows refrigerant control devices to be connected to both the upper and lower sides of the valve island 21 via the valve island interfaces 211, thereby improving the compact structure and reducing space occupation.

[0083] Furthermore, at least part of the valve island interface 211 is connected to a connecting pipe, which is connected to a refrigerant control device (e.g., Figure 4 The electronic expansion valve 61, four-way valve 62, plate heat exchanger 63, one-way solenoid valve 64, oil separator 65, and gas-liquid separator 30 shown are connected. Specifically, a connecting pipe connects the refrigerant control device to the valve island 21, and the refrigerant control device communicates with the flow channels within the valve island 21 through the connecting pipe and valve island interface 211. Some of the multiple refrigerant control devices are located on the upper side of the valve island 21 and connected to the valve island interface 211 located on the upper side of the valve island 21 through the connecting pipe; other refrigerant control devices are located on the lower side of the valve island 21 and connected to the valve island interface 211 located on the lower side of the valve island 21 through the connecting pipe. This facilitates the connection and communication of the refrigerant control devices to the valve island 21.

[0084] Furthermore, the valve island interface 211 of the valve island 21 can also be connected to the compressor 50 and the outdoor heat exchanger of the air conditioner 100 through a connecting pipe to form a refrigerant circulation loop of the air conditioner.

[0085] In some examples, at least a portion of the multiple connecting pipes is a straight pipe. This simplifies the structure of the connecting pipes. Furthermore, at least a portion of the multiple connecting pipes is made of stainless steel. This improves the structural strength and service life of the connecting pipes.

[0086] Furthermore, among the multiple valve island interfaces 211, some valve island interfaces 211 can have their openings facing vertically, while others can have their openings facing horizontally. This facilitates the connection of refrigerant control devices and also avoids interference between multiple refrigerant control devices.

[0087] In some embodiments of this utility model, such as Figure 4 As shown, the air conditioner 100 also includes a plate heat exchanger 63, which is connected in series between the outdoor heat exchanger and the return port of the compressor 50 to provide gas replenishment and enthalpy enhancement to the compressor 50. The plate heat exchanger 63 has a first flow channel and a second flow channel for mutual heat exchange, both of which are used for the flow of refrigerant.

[0088] Furthermore, the plate heat exchanger 63 is connected to at least one valve island interface 211 on the valve island 21, so that the first flow channel and the second flow channel are in communication with the channels within the valve island 21. For example, the two ends of the first flow channel and the second flow channel of the plate heat exchanger 63 are respectively connected to the corresponding four valve island interfaces 211.

[0089] In some examples, such as Figure 4 and Figure 5 As shown, the plate heat exchanger 63 is arranged on the lower side of the valve island 21. The air conditioner 100 also includes a mounting bracket 70, through which the plate heat exchanger 63 is fixed to the gas-liquid separator 30. This not only facilitates the fixing of the plate heat exchanger 63, but also shortens the distance between the plate heat exchanger 63 and the valve island 21, making it easier to connect the plate heat exchanger 63 to the valve island 21.

[0090] In some embodiments of this utility model, such as Figure 1 As shown, the structural support may include at least one of the following: a partition plate 11, a heat exchanger side plate 12, a side plate of the shell 10, a terminal block 14, and an electrical control box mounting plate 15. That is, the structural support may be one of the following: a partition plate 11, a heat exchanger side plate 12, a side plate of the shell 10, a terminal block 14, and an electrical control box mounting plate 15. The structural support may also include any two, three, or four of the following: a partition plate 11, a heat exchanger side plate 12, a side plate of the shell 10, a terminal block 14, and an electrical control box mounting plate 15. Furthermore, the structural support may simultaneously include the following: a partition plate 11, a heat exchanger side plate 12, a side plate of the shell 10, a terminal block 14, and an electrical control box mounting plate 15.

[0091] It should be noted that when there are multiple structural support components, the valve island 21 can connect multiple structural support components one-to-one through multiple connecting brackets 40. Of course, the valve island 21 can also connect multiple structural support components simultaneously through one connecting bracket 40. In other examples, the valve island 21 can also connect the same structural support component through multiple connecting brackets 40.

[0092] In this embodiment, the structural support includes at least one of the following: a central partition plate 11, a heat exchanger side plate 12, a side plate of the housing 10, a wiring board 14, and an electrical control box mounting plate 15. The valve island 21 can be connected to the central partition plate 11, the heat exchanger side plate 12, the side plate of the housing 10, the wiring board 14, and / or the electrical control box mounting plate 15 via the connecting bracket 40. This reduces the distance between the valve island 21 and the structural support, facilitates the fixing of the valve island 21, improves the reliability and stability of fixing the valve island 21, and also makes the structure of the air conditioner 100 more compact, reducing the space occupied by the connecting bracket 40.

[0093] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the structural support may include a partition plate 11, which is located inside the housing 10 and divides the space inside the housing 10 into a compressor chamber and a fan chamber arranged on the left and right. The valve island 21 and the shut-off valve 66 are both located inside the compressor chamber. The connecting bracket 40 includes a first bracket 41, which is connected between the partition plate 11 and the valve island 21.

[0094] For example Figure 1 As shown, the air conditioner 100 is a split-type air conditioner and includes an outdoor unit. The outdoor unit includes a housing 10, and a partition 11 is provided inside the housing 10. The partition 11 extends front and back and divides the space inside the housing 10 into a compressor chamber and a fan chamber arranged on the left and right. The compressor chamber is located on the right side of the partition 11. The gas-liquid separator 30 and the compressor 50 are both located in the compressor chamber, and the compressor 50 is located in front of the gas-liquid separator 30. The valve island 21 is arranged on the front side of the top of the gas-liquid separator 30. The rear end of the valve island 21 is fixedly connected to the gas-liquid separator 30. The first bracket 41 is arranged on the left side of the valve island 21 and extends to the left to the position of the partition 11 to be fixedly connected to the partition 11.

[0095] In this embodiment, by using the rear end of the valve island 21 to fix the gas-liquid separator 30 and fixing the left end to the middle partition plate 11 via the first bracket 41, the reliability of the fixed connection of the valve island 21 can be further improved, reducing the risk of the valve island 21 shaking. Connecting the valve island 21 to the middle partition plate 11 via the first bracket 41 simplifies the structure and size of the first bracket 41, resulting in a compact structure that improves the space utilization within the housing 10 while ensuring the valve island 21 is fixed.

[0096] In some embodiments of this utility model, such as Figure 1 , Figure 4 and Figure 7 As shown, along the left-right direction, the first bracket 41 is arranged between the valve island 21 and the middle partition 11. The first bracket 41 is a plate shape that extends left and right. The end of the first bracket 41 facing the middle partition 11 has a first folded edge 411 that folds up and down. The first bracket 41 is connected to the middle partition 11 through the first folded edge 411.

[0097] For example Figure 7 As shown, the first bracket 41 is a rectangular plate with a horizontal orientation. The right end of the first bracket 41 overlaps and connects with the valve island 21. The left end of the first bracket 41 is provided with an upwardly folded first folded edge 411. The first folded edge 411 extends into a long strip shape in the front-back direction. The first folded edge 411 is attached to and fixedly connected with the middle partition plate 11.

[0098] In this embodiment, by forming a first folded edge 411 connected to the middle partition 11, the contact area between the first support 41 and the middle partition 11 can be increased, thereby improving the reliability between the first support 41 and the middle partition 11, and thus improving the reliability of the fixed connection of the valve island 21 and reducing the risk of the valve island 21 shaking.

[0099] In some embodiments of this utility model, such as Figure 1 , Figure 4 and Figure 7 As shown, a plurality of first fixing holes 4111 are formed on the first folded edge 411, and a plurality of second fixing holes 111 are provided on the middle partition plate 11. A plurality of first fasteners are inserted into the first fixing holes 4111 and the second fixing holes 111 so that the first folded edge 411 is fastened to the middle partition plate 11.

[0100] For example, the number of first fixing holes 4111 on the first folded edge 411 can be two, three, four, five, six or more, and the multiple first fixing holes 4111 can be arranged at intervals along the front-back direction. The number of second fixing holes 111 on the middle partition 11 corresponds one-to-one with the multiple first fixing holes 4111, and they are directly opposite each other in the left-right direction.

[0101] In this embodiment, the first folded edge 411 is fastened to the middle partition plate 11 by multiple first fasteners, which can facilitate the installation and disassembly of the first bracket 41 and the middle partition plate 11, facilitate the installation and disassembly of the valve island 21, improve assembly efficiency, and facilitate the maintenance and replacement of the valve island 21.

[0102] In some examples, the surface of the first flange 411 facing away from the partition plate 11 is provided with a raised first boss. There are multiple first bosses, and each of the multiple first bosses corresponds to a multiple first fixing holes 4111. The first fixing holes 4111 pass through the corresponding first bosses in the left and right directions. This can enhance the structural strength of the periphery of the first fixing holes 4111, extend the depth of the first fixing holes 4111, increase the mating length between the first fastener and the first fixing holes 4111, and improve the connection reliability.

[0103] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, a first reinforcing rib 412 is formed on the first bracket 41, and / or a first reinforcing flange 413 is formed around the periphery of the first bracket 41. This improves the structural strength of the first bracket 41 and enhances the reliability of the valve island 21 being fixed to the partition plate 11 via the first bracket 41.

[0104] For example Figure 8 As shown, the first bracket 41 includes a first plate and a first flange 411. The first plate is a horizontally arranged rectangular plate. The first flange 411 is connected to the left edge of the first plate and extends upward. The front and rear edges of the first flange 411 are flush with the front and rear edges of the first plate, respectively. A portion of the first plate protrudes in the vertical direction to form a first reinforcing rib 412, which can be rectangular. A first reinforcing flange 413 is formed on the first bracket 41. The first reinforcing flange 413 is formed on the front and rear edges of the first plate and extends upward. The first reinforcing flange 413 is also formed on the front, upper, and rear edges of the first flange 411 and extends to the right. A plurality of first through holes 414 are formed on the right edge of the first plate at intervals. The plurality of first through holes 414 are arranged at intervals in the front-rear direction. The first bracket 41 is connected to the valve island 21 by fasteners passing through the first through holes 414.

[0105] According to some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the structural support includes: heat exchanger side plate 12, and connecting bracket 40 includes a second bracket 42, which is connected between heat exchanger side plate 12 and valve island 21.

[0106] like Figure 9The housing 10 contains a central partition 11, which is vertically arranged and extends forward and backward. A heat exchanger side plate 12 is arranged on the rear side of the central partition 11 and is fixedly connected to one end of the outdoor heat exchanger in the left-right direction for installing and fixing the outdoor heat exchanger. The heat exchanger side plate 12 extends into a long strip in the vertical direction. A second bracket 42 is arranged on the side of the valve island 21 facing the central partition 11 in the left-right direction and is fixed to the left edge of the valve island 21. The rear end of the second bracket 42 extends rearward to the heat exchanger side plate 12 for fixed connection. At the same time, the rear edge of the valve island 21 is fixedly supported on the upper surface of the gas-liquid separator 30.

[0107] In this embodiment, by using the rear end of the valve island 21 to fix the gas-liquid separator 30 and the left end to be fixed by the second bracket 42, and then fixedly connected to the rear heat exchanger side plate 12 by the second bracket 42, the reliability of the fixed connection of the valve island 21 can be further improved, and the risk of valve island 21 shaking can be reduced. Connecting the valve island 21 to the middle heat exchanger side plate 12 by the second bracket 42 simplifies the structure and size of the second bracket 42, resulting in a compact structure that improves the space utilization within the housing 10 while still securing the valve island 21.

[0108] In some embodiments of this utility model, such as Figure 9 , Figure 10 and Figure 12 As shown, the second bracket 42 extends in the front-to-back direction, and the rear end of the second bracket 42 forms a second folded edge 421 that folds to one side in the left-to-right direction. The second bracket 42 is fixedly connected to the heat exchanger side plate 12 through the second folded edge 421.

[0109] like Figure 9 , Figure 10 and Figure 12 As shown, the second support 42 is arranged on the lower side of the valve island 21. The second support 42 is a plate shape that is vertically arranged and extends in the front-back direction. The rear edge of the second support 42 is provided with a second folded edge 421 that bends to the right. The second folded edge 421 extends in the up-down direction. The heat exchanger side plate 12 includes a side plate body and a third folded edge 121. The side plate body is a plate shape that is arranged perpendicular to the left-right direction. The third folded edge 121 is connected to the front edge of the side plate body and extends to the right. The rear surface of the second folded edge 421 is attached to and fixedly connected to the front surface of the third folded edge 121.

[0110] In this embodiment, by forming a first folded edge 411 at the rear end of the second bracket 42 and connecting it to the heat exchanger side plate 12, the contact area between the second bracket 42 and the heat exchanger side plate 12 can be increased, thereby improving the reliability of the connection between the second bracket 42 and the heat exchanger side plate 12, and thus improving the reliability of the fixed connection of the valve island 21 and reducing the risk of the valve island 21 shaking.

[0111] In some embodiments of this utility model, such as Figure 10 and Figure 15 As shown, a plurality of first fastening holes 4211 are formed on the second folded edge 421, and a plurality of second fastening holes 1211 are provided on the heat exchanger side plate 12. A plurality of second fasteners are inserted into the first fastening holes 4211 and the second fastening holes 1211 so that the second folded edge 421 is fastened to the heat exchanger side plate 12.

[0112] For example Figure 10 and Figure 15 As shown, the number of first fastening holes 4211 on the second folded edge 421 can be two, three, four, five, six or more, and the multiple first fastening holes 4211 can be arranged at intervals along the vertical direction. The number of second fastening holes 1211 on the third folded edge 121 of the heat exchanger side plate 12 corresponds one-to-one with the multiple first fastening holes 4211, and the first fastening holes 4211 and the corresponding second fastening holes 1211 are directly opposite each other in the front-back direction.

[0113] In this embodiment, the second folded edge 421 is fastened to the heat exchanger side plate 12 by multiple second fasteners, which facilitates the installation and disassembly of the second bracket 42 and the heat exchanger side plate 12, facilitates the installation and disassembly of the valve island 21, improves assembly efficiency, and facilitates the maintenance and replacement of the valve island 21.

[0114] In some examples, such as Figure 10 As shown, the surface of the third fold 121 of the heat exchanger side plate 12 opposite to the second fold 421 is provided with a raised second boss. There are multiple second bosses, and each of the multiple second bosses corresponds to a multiple second fastening holes 1211. The second fastening holes 1211 pass through the corresponding second bosses in the front-back direction. This can enhance the structural strength of the periphery of the second fastening holes 1211, extend the depth of the second fastening holes 1211, increase the mating length between the second fastener and the second fastening holes 1211, and improve the connection reliability.

[0115] In some embodiments of this utility model, such as Figure 15 As shown, a second reinforcing rib 422 is formed on the second support 42, and / or a second reinforcing flange 423 is formed around the periphery of the second support 42. This improves the structural strength of the second support 42 and enhances the reliability of the valve island 21 being fixed to the heat exchanger side plate 12 via the second support 42.

[0116] For example Figure 15As shown, the second support 42 includes a second plate and a second folded edge 421. The second plate is a vertically arranged plate. The second folded edge 421 is connected to the rear edge of the second plate and extends to the right. The upper and lower edges of the second folded edge 421 are flush with the upper and lower edges of the second plate, respectively. A portion of the second plate is bent to one side in the left-right direction to form a second reinforcing rib 422. The second reinforcing rib 422 extends in the up-down direction. A second reinforcing flange 423 is formed on the second support 42. The second reinforcing flange 423 is formed on the upper edge of the second plate and extends to the right. The second reinforcing flange 423 is also formed on the upper and right edges of the second folded edge 421 and extends to the front.

[0117] In some embodiments of this utility model, such as Figure 16 and Figure 19 As shown, the structural support includes a terminal block 14 and / or an electrical control box mounting plate 15 arranged on the upper side of the valve island 21. The connecting bracket 40 includes a third bracket 43, and the valve island 21 is connected to the terminal block 14 and / or the electrical control box mounting plate 15 through the third bracket 43. The terminal block 14 is configured for wiring various electrical components inside the outdoor unit of the air conditioner, and the electrical control box mounting plate 15 is used for installing and fixing the electrical control box of the air conditioner 100.

[0118] like Figure 16 As shown, a partition plate 11 is provided inside the housing 10. The partition plate 11 is vertically arranged and extends front to back. A wiring plate 14 is arranged on the side of the partition plate 11 facing the compressor cavity. The wiring plate 14 is vertically arranged and extends left to right. The left end of the wiring plate 14 is fixedly connected to the partition plate 11, and the right end of the wiring plate 14 is adapted to connect to the right side plate of the housing 10. Further, the wiring plate 14 is located at the front or front side of the valve island 21. The third bracket 43 extends vertically. The upper end of the third bracket 43 is fixed to the wiring plate 14, and the lower end of the third bracket 43 is fixedly connected to the front end of the valve island 21. The rear end of the valve island 21 is fixed and supported on the upper end face of the gas-liquid separator 30.

[0119] like Figure 19 As shown, the electrical control box mounting plate 15 is arranged on the side of the partition plate 11 facing the compressor cavity. The electrical control box mounting plate 15 is vertically arranged and extends to the left and right. The left end of the electrical control box mounting plate 15 is fixedly connected to the partition plate 11, and the right end of the electrical control box mounting plate 15 is adapted to connect to the right side plate of the housing 10. Further, the electrical control box mounting plate 15 is located above the valve island 21 and is arranged at the front of the compressor cavity. The third bracket 43 extends vertically. The upper end of the third bracket 43 is fixed to the electrical control box mounting plate 15, and the lower end of the third bracket 43 is fixedly connected to the front end of the valve island 21. The rear end of the valve island 21 is fixed and supported on the upper end face of the gas-liquid separator 30.

[0120] In this embodiment, by using the rear end of the valve island 21 to fix the gas-liquid separator 30 and the front end to fix it to the terminal block or electrical control box mounting plate 15 via the third bracket 43, the reliability of the fixed connection of the valve island 21 can be further improved and the risk of the valve island 21 shaking can be reduced.

[0121] It should be noted that the number of third brackets 43 can be one, with the valve island 21 connected to the terminal block 14 via one third bracket 43, or the valve island 21 connected to the electrical control box mounting plate 15 via one third bracket 43, or the upper end of the third bracket 43 can be connected to both the terminal block 14 and the electrical control box mounting plate 15 simultaneously. The number of third brackets 43 can also be multiple, for example, two third brackets 43, one connected between the valve island 21 and the electrical control box mounting plate 15, and the other connected between the valve island 21 and the terminal block 14.

[0122] In some embodiments of this utility model, such as Figure 18 and Figure 21 As shown, the third support 43 includes multiple vertical plate portions 431 and horizontal plate portions 432. The horizontal plate portions 432 extend horizontally and are fixedly connected to the valve island 21. The multiple vertical plate portions 431 extend vertically and are spaced apart in the horizontal plane. The lower end of the vertical plate portions 431 is connected to the horizontal plate portions 432, and the upper end of the vertical plate portions 431 is connected to a structural support member (e.g., Figure 18 The terminal block 14 shown is or Figure 21 The electrical control box mounting plate 15 shown in the figure.

[0123] In this embodiment, the third bracket 43, by providing multiple spaced vertical plates 431, reduces the material usage of the third bracket 43 while simplifying its structure and lowering costs, all while connecting the third bracket 43 to the terminal block 14 or the electrical control box mounting plate 15. Furthermore, it allows the third bracket 43 to have multiple connection points with the terminal block 14 or the electrical control box mounting plate 15, thereby reducing stress at individual connection points and improving the reliability of the connection between the third bracket 43 and the terminal block 14 or the electrical control box mounting plate 15.

[0124] In some embodiments of this utility model, such as Figures 17-21As shown, the horizontal plate portion 432 is arranged on the lower side of the valve island 21, and multiple vertical plate portions 431 are respectively arranged on opposite sides of the valve island 21 in the left-right direction. In this embodiment, by arranging the horizontal plate portion 432 on the lower side of the valve island 21, the horizontal plate portion 432 can support the valve island 21 from below, improving the fixed support effect of the valve island 21. It also avoids interference between the horizontal plate portion 432 and the valve island interface 211 located on the upper side of the valve island 21, facilitating the connection between the horizontal plate portion 432 and the valve island 21. Furthermore, it increases the contact area between the valve island 21 and the third support 43, allowing the weight of the valve island 21 to be evenly distributed on the horizontal plate portion 432, further improving the stability of the valve island 21 support and reducing the probability of the valve island 21 swaying. In addition, by arranging multiple vertical plate portions on the left and right sides of the valve island respectively, this embodiment facilitates the connection between the vertical plate portion 431 and the horizontal plate portion 432, making the structural arrangement of the third support 43 and the valve island 21 more compact and reasonable.

[0125] In some embodiments of this utility model, such as Figure 18 and Figure 21 As shown, the upper end of the vertical plate 431 is fastened to the structural support member by a third fastener. This facilitates the installation and removal of the vertical plate 431 from the wiring board 14 or the electrical control box mounting plate 15, improving assembly efficiency and facilitating the maintenance and replacement of the valve island 21.

[0126] For example, a first mounting hole is formed at the upper end of the vertical plate portion 431, which extends through the thickness direction of the vertical plate portion 431. A second mounting hole is formed on the wiring board 14. The multiple first mounting holes and the multiple second mounting holes correspond one to one and face each other. The third fastener passes through the first mounting hole and the corresponding second mounting hole in sequence to fix the vertical plate portion 431 to the wiring board 14.

[0127] For example, a first mounting hole is formed at the upper end of the vertical plate 431, which extends through the vertical plate 431 along its thickness direction. A plurality of third mounting holes are formed on the electrical control box mounting plate 15. The plurality of first mounting holes correspond one-to-one with the plurality of third mounting holes and are directly opposite each other. The third fastener passes through the first mounting hole and the corresponding third mounting hole in sequence to fix the vertical plate 431 to the electrical control box mounting plate 15.

[0128] In some embodiments of this utility model, such as Figure 18 and Figure 21 As shown, the vertical plate portion 431 extends into a long strip in the vertical direction, and at least two vertical plate portions 431 are arranged to intersect in the thickness direction. Thus, multiple vertical plate portions 431 can be positioned and assembled with the terminal block 14 or the electrical control box mounting plate 15 in multiple directions, improving the reliability and stability of the connection between the third bracket 43 and the terminal block 14.

[0129] For example Figure 18As shown, the third bracket 43 includes two vertical plate portions 431. The vertical plate portion 431 connected to the left end of the horizontal plate portion 432 is the first vertical plate portion. The width direction of the first vertical plate portion is along the left-right direction and the thickness direction is along the front-back direction. The first mounting hole on the first vertical plate portion passes through the first vertical plate portion in the front-back direction. The first vertical plate portion is arranged on the front side of the terminal block 14 and is in contact with the front surface of the terminal block 14. Further, the vertical plate portion 431 connected to the right end of the horizontal plate portion 432 is the second vertical plate portion. The width direction of the second vertical plate portion is along the front-back direction and the thickness direction is along the left-right direction. The first mounting hole on the second vertical plate portion passes through the second vertical plate portion in the left-right direction. The second vertical plate portion is arranged on the right side of the terminal block 14 and is adapted to be in contact with the right side surface of the terminal block 14.

[0130] In some embodiments of this utility model, such as Figure 20 As shown, the horizontal plate 432 is a long strip extending in the left-right direction, and multiple vertical plates 431 are respectively connected to both ends of the horizontal plate 432 in the length direction and connected to the electrical control box mounting plate 15. Alternatively, the horizontal plate 432 includes a first segment 4321 and a second segment 4322. The first segment 4321 extends left and right, and the second segment 4322 is connected to the left end of the first segment 4321 and extends forward. Multiple vertical plates 431 are respectively connected to the opposite ends of the first segment 4321 and the second segment 4322 and connected to the terminal block 14. This simplifies the structure of the third bracket 43 and facilitates its manufacturing.

[0131] For example Figure 20 As shown, the horizontal plate 432 is a long rectangular plate extending from left to right. The third support 43 includes two vertical plates 431, which are the first vertical plate and the second vertical plate, respectively. The first vertical plate extends vertically and is a long rectangular plate that is generally perpendicular to the front-back direction. The first vertical plate is connected to the front edge of the left end of the horizontal plate 432, and the left edge of the first vertical plate is flush with the left edge of the horizontal plate 432. The second vertical plate extends vertically and is a long rectangular plate that is perpendicular to the left-back direction. The second vertical plate is connected to the right edge of the horizontal plate 432, and the front and rear edges of the second vertical plate are flush with the front and rear edges of the horizontal plate 432, respectively.

[0132] For example Figure 17 As shown, the third support 43 includes a horizontal plate portion 432 and two vertical plate portions 431. The horizontal plate portion 432 includes a first segment 4321 and a second segment 4322 connected in an L-shape. The first segment 4321 is a long rectangular plate that is horizontally set and extends to the left and right. The second segment 4322 is a long rectangular plate that is horizontally set and extends to the front and back. The left edge of the first segment 4321 is flush with the left edge of the second segment 4322. One of the two vertical plate portions 431 is connected to the right edge of the first segment 4321, and the other is connected to the front edge of the second segment 4322.

[0133] Furthermore, the third bracket 43 is a single piece, which reduces the number of parts and improves the reliability of the connection between the horizontal plate 432 and the vertical plate 431.

[0134] In some embodiments of this utility model, the connecting bracket 40 and the valve island 21 are fastened together by a fourth fastener. This embodiment uses a fourth fastener to fasten the connecting bracket 40 and the valve island 21, which facilitates the installation and disassembly of the connecting bracket 40 and the valve island 21, improves assembly efficiency, and facilitates the maintenance and replacement of the valve island 21.

[0135] like Figure 6 and Figure 7 As shown, the right side edge of the first bracket 41 extends to the lower side of the valve island 21 and forms a plurality of first through holes 414 spaced apart. The plurality of first through holes 414 are spaced apart in the front-back direction. The left side edge of the valve island 21 is provided with a plurality of third through holes 212 spaced apart. The first bracket 41 is fastened to the valve island 21 by a fourth fastener passing through the first through holes 414 and the third through holes 212.

[0136] like Figure 14 As shown, the upper edge of the second bracket 42 has a connecting lug 424 bent to one side in the left-right direction. A second through hole 425 is formed on the connecting lug 424. Furthermore, there are multiple connecting lugs 424, spaced apart in the front-back direction. There are also multiple second through holes 425, each corresponding to one of the connecting lugs 424. The left edge of the valve island 21 has multiple third through holes 212 arranged at intervals in the front-back direction. The second bracket 42 is fixedly connected to the valve island 21 by a fourth fastener passing through the second through holes 425 and the third through holes 212.

[0137] In some embodiments of this utility model, the air conditioner 100 further includes a valve plate 22, which is connected to the valve island 21, and a shut-off valve 66 is fixed on the valve plate 22. In this embodiment, the valve plate 22 is directly disposed on the valve island 21. Thus, during the final assembly of the air conditioner 100, it is unnecessary to connect the valve plate 22 to other parts, thereby further improving the assembly efficiency of the air conditioner 100 during final assembly. Furthermore, in this embodiment, the valve plate 22 can be fixed only to the valve island 21 without being connected to other components. This reduces the direct transmission of vibration from the shut-off valve 66 disposed on the valve plate 22 to the housing 10 or other components of the air conditioner 100. Additionally, in this embodiment, the shut-off valve 66 is fixed to the valve plate 22, allowing the shut-off valve 66 to be indirectly supported on the valve island 21 via the valve plate 22. This facilitates the support and installation of the shut-off valve 66 and reduces interference between the shut-off valve 66 and other components integrated on the valve island 21.

[0138] In some embodiments of this invention, the valve island 21 and the valve plate 22 are integrally formed. In this case, the connecting bracket 40 is connected to the valve island 21 to fix and support the valve island 21. This reduces the number of parts and improves assembly efficiency.

[0139] In some embodiments of this utility model, the valve island 21 and the valve plate 22 are separate components and fixedly connected. The valve island 21 and the valve plate 22 can be welded, screwed, or snap-fitted together. This allows for convenient separate processing of the valve island 21 and the valve plate 22, reducing processing difficulty.

[0140] like Figure 6 As shown, valve island 21 and valve plate 22 are arranged in a front-to-back direction, with valve plate 22 positioned on the front side of valve island 21. Furthermore, the front edge of valve island 21 has multiple first through holes 213 spaced apart from left to right, and the rear edge of valve plate 22 has multiple second through holes spaced apart from left to right. Screws and fasteners pass through the first and second through holes 213 and 213 to fix valve plate 22 to valve island 21. This allows for convenient separate processing of valve island 21 and valve plate 22, reducing processing difficulty and improving processing efficiency.

[0141] Furthermore, the valve plate 22 includes a horizontal plate portion and a mounting plate portion. The horizontal plate portion is a horizontally arranged flat plate. Multiple second through holes are formed along the rear edge of the horizontal plate portion. The mounting plate portion is connected to the front edge of the horizontal plate portion and extends vertically upward. Two mounting notches are formed along the upper edge of the mounting plate portion, spaced apart on the left and right sides. Two shut-off valves 66 are arranged on the front side of the mounting plate portion, and the connecting pipes of the shut-off valves 66 pass through the mounting notches to connect with the valve island interface 211 on the valve island 21. Furthermore, a third reinforcing flange is formed around the periphery of the valve plate 22. The third reinforcing flange is formed on the left and right sides of the horizontal plate portion and extends upward. The third reinforcing flange is formed on the left and right sides and the upper edge of the mounting plate portion and extends rearward.
