Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0142] The following is for reference. Figures 1-52 This invention describes an air conditioner 100 according to an embodiment of the present invention. The air conditioner 100 in this embodiment can be an integrated air conditioner 100 or a split-type air conditioner 100. When the air conditioner 100 in this embodiment is a split-type air conditioner 100, the air conditioner 100 can include a separate indoor unit and an outdoor unit.

[0143] Reference Figure 1 , Figure 2 and Figure 3 The air conditioner 100 according to an embodiment of the present utility model includes: a housing 10, a valve island 21, and functional components.

[0144] Specifically, the air conditioner 100 is provided with a housing 10, which is located on the outside of the air conditioner 100 and thus provides support for the air conditioner 100. An installation space is formed inside the housing 10, in which various structures required for the operation of the air conditioner 100 can be installed. The housing 10 can protect these structures and also provide installation points for the various structures inside the air conditioner 100, thus ensuring installation reliability.

[0145] The housing 10 can house a compressor 50 and multiple refrigerant piping components. These components may include a four-way valve 62, an electronic expansion valve 61, a plate heat exchanger 63, a gas-liquid separator 30, an oil-liquid separator 65, a solenoid valve, a high-pressure valve, and a low-pressure valve. These components are connected to the compressor 50 to form a refrigerant circuit, ensuring the reliable operation of the air conditioner 100. At least one of the following components—compressor 50, four-way valve 62, electronic expansion valve 61, plate heat exchanger 63, gas-liquid separator 30, oil-liquid separator 65, solenoid valve, high-pressure valve, and low-pressure valve—is a functional component connected to the valve island 21.

[0146] Valve island 21 defines a refrigerant flow path. At least one functional component is connected to the refrigerant flow path of valve island 21, and multiple refrigerant piping components can be connected to compressor 50 through the refrigerant flow path of valve island 21 to form a refrigerant circuit. In some preferred embodiments, multiple refrigerant piping components and compressor 50 are all connected to the refrigerant flow path of valve island 21.

[0147] It should be noted that the functional components are connected to the refrigerant flow channel of the valve island 21. This connection can be either a direct connection or a connection via a pipeline. This application does not impose any restrictions on this connection.

[0148] By setting up an integrated valve island 21, the length of the refrigerant piping inside the air conditioner can be shortened, reducing the space occupied by multiple refrigerant piping lines. This improves integration, resulting in lighter weight and lower installation costs. At the same time, it reduces the number of connection points for multiple refrigerant piping lines, thereby reducing the risk of refrigerant and other media leakage and improving the reliability of the air conditioner 100.

[0149] In this embodiment of the utility model, the housing 10 is provided with a structural support member, and the valve island 21 is positioned and installed on the structural support member.

[0150] Reference Figure 1 , Figure 9 , Figure 16 and Figure 19 Structural support members refer to structural members on or within the housing 10 that serve to install and support other components located within the housing 10. For example, a structural support member can be at least one side plate of the housing 10. The side plate of the housing 10 can include a top plate, a chassis 13, a front panel, a rear side plate, a left side plate, a right side plate, and a central partition 11. Another example is that a structural support member can be a heat exchanger side plate 12, a wiring board 14, an electrical control box mounting plate 15, a fan mounting bracket, etc.

[0151] Valve island 21 is positioned and installed on the structural support, which helps improve the stability of valve island 21. When the air conditioner 100 is running, the compressor 50 will generate continuous vibration. The vibration energy can be transmitted to valve island 21 and refrigerant piping components through the pipeline. In this embodiment of the utility model, valve island 21 is installed on the structural support, which can disperse the vibration energy to the structural support, reduce the swaying amplitude of valve island 21 and pipeline, reduce the damage of vibration to precision components and connection points, and help extend the service life of air conditioner 100.

[0152] The performance of some refrigerant piping components is closely related to their installation position. For example, the four-way valve 62 requires precise internal slider movement; if its position is off, refrigerant cross-flow may occur. The electronic expansion valve 61 needs to maintain coaxiality with the preceding and following pipes; otherwise, the valve port may not seal properly due to pipe stress, affecting the refrigerant throttling effect. In this embodiment, the integrated valve island 21 is installed on the structural support, which can position the valve island 21, thereby ensuring the installation position accuracy of the refrigerant piping components connected to the valve island 21 and maintaining performance stability.

[0153] According to the embodiment of this utility model, the air conditioner 100 integrates the refrigerant circuit inside the air conditioner 100 through the valve island 21, thereby improving weight reduction and lowering installation costs. Simultaneously, it reduces the number of connection points for multiple refrigerant pipes, thus reducing the risk of refrigerant leakage and improving the reliability of the air conditioner 100. The valve island 21 is positioned and installed on the structural support, ensuring the stability of its installation. It also reduces the swaying amplitude of the valve island 21 and the pipes, minimizing vibration damage to precision components and connection points, and extending the service life of the air conditioner 100. Furthermore, it positions the valve island 21, ensuring the installation accuracy of the refrigerant pipe components connected to it and maintaining performance stability.

[0154] Reference Figure 6 and Figure 7 In some embodiments, multiple refrigerant channels can be formed within the valve island 21. These multiple refrigerant channels can be independent of each other, or they can be interconnected. Alternatively, some refrigerant channels can be interconnected while others are independent. Multiple valve island interfaces 211 are also formed on the valve island 21. Each refrigerant channel is connected to at least two valve island interfaces 211. The valve island 21 is connected to functional components through the valve island interfaces 211.

[0155] Reference Figure 3 , Figure 4 and Figure 6Specifically, valve island 21 is connected to control valves such as electronic expansion valve 61, four-way valve 62, one-way solenoid valve 64, and shut-off valve 66 through valve island interface 211. Valve island 21 is also connected to plate heat exchanger 63 for enthalpy increase through valve island interface 211, and also to gas-liquid separator 30, oil-liquid separator 65, and compressor 50 through valve island interface 211. In this way, valve island 21 connects and connects multiple control valves, gas-liquid separator 30, plate heat exchanger 63, and compressor 50 in series through multiple valve island interfaces 211 to form the refrigerant flow path of air conditioner 100.

[0156] 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.

[0157] In some embodiments of this utility model, such as Figures 3-6 As 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.

[0158] 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.

[0159] 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.

[0160] Reference Figure 7 , Figure 30 and Figure 31In 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. Therefore, refrigerant control devices can 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.

[0161] Reference Figure 25 In some embodiments, the valve island 21 includes a first raft plate 217 and a valve body connector 2171. The valve body connector 2171 defines at least one valve island interface 211. The first raft plate 217 defines a first surface a. The first surface a is provided with the valve body connector 2171. There are multiple valve body connectors 2171, which are used to connect to a control valve.

[0162] Multiple valve body connectors 2171 are provided on the first surface a of the first raft plate 217. The multiple valve body connectors 2171 are used to connect control valves (such as four-way valve 62, low-pressure valve, high-pressure valve and one-way solenoid valve 64, etc.). Multiple control valves can be arranged in a compact manner to reduce the length of the connecting pipeline, reduce pipe resistance and pressure loss, thereby reducing heat loss, and also reducing costs, improving space occupation and reducing layout difficulty.

[0163] Reference Figure 25 and Figure 26 It should be noted that the first surface a can be located on the upper side of the valve island 21 or on the horizontal side of the valve island 21, as long as it facilitates the connection of the valve body connector 2171 to the valve body. This utility model does not impose any restrictions on this.

[0164] Reference Figure 3 In some embodiments, the valve body connector 2171 includes at least one expansion valve connector, a four-way valve connector, a high-pressure valve connector, and a low-pressure valve connector, wherein the expansion valve connector, the four-way valve connector, the low-pressure valve connector, and the high-pressure valve connector are respectively used to connect the electronic expansion valve 61, the four-way valve 62, the low-pressure valve, and the high-pressure valve.

[0165] It should be noted that when the air conditioner 100 has an enthalpy-increasing branch, at least two electronic expansion valves 61 need to be installed in the refrigerant circuit, and the corresponding valve body connector 2171 includes at least two expansion valve connectors. When the air conditioner 100 does not have an enthalpy-increasing branch, at least one electronic expansion valve 61 needs to be installed in the refrigerant circuit, and the corresponding valve body structure should include at least one expansion valve connector.

[0166] 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 3The 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.

[0167] 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 100.

[0168] 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.

[0169] 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.

[0170] In some embodiments, at least a portion of the valve island 21 is made of stainless steel, thereby ensuring the structural strength of the integrated valve island 21 and improving the reliability of its use. It should be understood that in other embodiments, the valve island 21 may also be made of carbon steel, aluminum alloy, or other materials, and this invention does not limit this to such materials.

[0171] In some embodiments, 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.

[0172] There can be one or two shut-off valves 66. For example, there are two shut-off valves 66, which are a high-pressure valve and a low-pressure valve, respectively. Both the high-pressure valve and the low-pressure valve are connected to the indoor heat exchanger through refrigerant pipelines.

[0173] Reference Figure 6 , Figure 33 and Figure 37 In some embodiments of this utility model, the air conditioner 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 not necessary 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 and not connected to other components. This reduces the direct transmission of vibration of the shut-off valve 66 disposed on the valve plate 22 to the housing 10 or other components of the air conditioner 100. In addition, in this embodiment, the shut-off valve 66 is fixed on the valve island 21, so that the shut-off valve 66 is indirectly supported on the valve island 21 through 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.

[0174] In some embodiments of this invention, at least a portion of the valve plate 22 and the valve island 21 are integrally formed. This reduces the number of parts and improves assembly efficiency.

[0175] In some embodiments of this utility model, the valve plate 22 and the valve island 21 are separate components and fixedly connected. The valve plate 22 and the valve island 21 can be welded, screwed, or snap-fitted together. This allows for convenient separate processing of the valve island 21 and reduces processing difficulty.

[0176] like Figure 6 and Figure 33 As shown, valve island 21 and valve plate 22 are arranged in a front-rear 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 454 fasteners pass through the first and second through holes 213 and 2 through holes to fix valve plate 22 onto valve island 21. Therefore, valve island 21 and valve plate 22 can be easily processed separately, reducing processing difficulty and improving processing efficiency.

[0177] Furthermore, such as Figure 6 , Figure 7 and Figure 33As shown, the valve plate 22 includes a first plate portion 221 and a second plate portion 222. The first plate portion 221 is a horizontally arranged flat plate. Multiple second through holes are formed on the rear edge of the first plate portion 221. The second plate portion 222 is connected to the front edge of the first plate portion 221 and extends vertically upwards. Two mounting notches are formed on the upper edge of the second plate portion 222, spaced apart on the left and right sides. Two shut-off valves 66 (a high-pressure valve and a low-pressure valve) are arranged on the front side of the second plate portion 222, 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 first plate portion 221 and extends upwards. The third reinforcing flange is formed on the left and right sides and the upper edge of the second plate portion 222 and extends rearwards.

[0178] Reference Figure 1 , Figure 9 , Figure 16 and Figure 19 In some embodiments of this utility model, the structural support member may include at least one of the following: top plate, chassis 13, front panel, rear side plate, left side plate, right side plate, middle partition 11, heat exchanger side plate 12, wiring board 14, electrical control box mounting plate 15, and fan mounting bracket. In other words, the structural support component can be one of the following: top plate, chassis 13, front panel, rear side panel, left side panel, right side panel, central partition 11, heat exchanger side panel 12, terminal block 14, electrical control box mounting plate 15, and fan mounting bracket. The structural support component can also include any two, three, or four of the following: top plate, chassis 13, front panel, rear side panel, left side panel, right side panel, central partition 11, heat exchanger side panel 12, terminal block 14, electrical control box mounting plate 15, and fan mounting bracket. The structural support component can also simultaneously include the following: top plate, chassis 13, front panel, rear side panel, left side panel, right side panel, central partition 11, heat exchanger side panel 12, terminal block 14, electrical control box mounting plate 15, and fan mounting bracket.

[0179] Reference Figures 22-26 In some embodiments, the structural support includes a chassis 13 of the housing 10, which supports the valve island 21.

[0180] In this embodiment of the utility model, the valve island 21 is directly connected to the chassis 13, which ensures the convenience and reliability of the valve island 21 installation, effectively improves the swaying of the valve island 21, reduces the damage of vibration to precision parts and connection points, and helps to extend the service life of the air conditioner 100.

[0181] Reference Figure 23 , Figure 24 and Figure 25In some specific embodiments, the chassis 13 is provided with an upwardly protruding boss 131, the top of which is at least partially attached to the valve island 21 to support the valve island 21.

[0182] In the above technical solution, the chassis 13 supports the valve island 21 through the boss 131, which can raise the height of the valve island 21, reduce the risk of the valve island 21 coming into contact with condensate, and help extend the service life of the valve island 21.

[0183] In some embodiments, one of the chassis 13 and the valve island 21 is provided with a positioning post 132 and the other is provided with a positioning hole 214, with the positioning post 132 inserted into the positioning hole 214.

[0184] The above technical solution further improves the accuracy of valve island 21 positioning, thereby ensuring the installation position accuracy of refrigerant pipeline components connected to valve island 21 and maintaining performance stability.

[0185] In some specific embodiments, the chassis 13 is provided with an upwardly extending positioning post 132, and the valve island 21 is provided with a positioning hole 214 that penetrates itself. The positioning post 132 is inserted into the positioning hole 214 from the lower side of the valve island 21, and the fastener is inserted into the positioning hole 214 from the upper side of the valve island 21 and threadedly connected to the positioning post 132, thereby fixing the valve island 21 to the chassis 13.

[0186] In this embodiment of the utility model, the installation method of valve island 21 is simple, which is conducive to improving the installation efficiency of valve island 21.

[0187] It should be understood that in other embodiments, the valve island 21 can also be installed on the chassis 13 by means of snap-fit ​​connection, welding or bracket connection, and the present invention does not limit this.

[0188] In other embodiments, the structural support members may also be other structural components such as a top plate, front panel, rear side plate, left side plate, right side plate, central partition 11, heat exchanger side plate 12, wiring board 14, electrical control box mounting plate 15, and fan mounting bracket, and the valve island 21 may be directly installed on the structural support members. It should be understood that in other embodiments, the valve island 21 may also be indirectly installed on the structural support members through other structures.

[0189] Reference Figure 1 In some embodiments, 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.

[0190] In this embodiment of the utility model, the installation method of valve island 21 is simple, which reduces the cost of air conditioner 100.

[0191] 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.

[0192] According to some embodiments of this utility model, such as Figure 1 and Figure 4 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.

[0193] For example Figure 1 As shown, the air conditioner 100 is a split-type air conditioner 100, 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.

[0194] 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.

[0195] In some embodiments of this utility model, such as Figure 1 , Figure 5 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.

[0196] For example Figure 6 , Figure 7 and Figure 8 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.

[0197] 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.

[0198] In some embodiments of this utility model, such as Figure 1 , Figure 2 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.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] In some embodiments of this utility model, such as Figure 6 , Figure 7 and Figure 8As 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.

[0203] 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.

[0204] like Figure 6 and Figure 8 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.

[0205] 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.

[0206] like Figure 9As shown, a partition plate 11 is provided inside the housing 10. The partition plate 11 is vertically arranged and extends back and forth. A heat exchanger side plate 12 is arranged on the rear side of the partition plate 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 partition plate 11 in the left-right direction and is fixed to the left side 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.

[0207] 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.

[0208] In some embodiments of this utility model, such as Figure 11 , Figure 12 and Figure 15 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.

[0209] like Figure 13 , Figure 14 and Figure 15 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.

[0210] 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.

[0211] In some embodiments of this utility model, such as Figure 13 , Figure 14 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.

[0212] like Figure 13 , Figure 14 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.

[0213] 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.

[0214] 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.

[0215] 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.

[0216] 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.

[0217] like Figure 15 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.

[0218] 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 100, and the electrical control box mounting plate 15 is used for installing and fixing the electrical control box of the air conditioner 100.

[0219] 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.

[0220] like Figure 19As 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.

[0221] 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 wiring board 14 or the 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.

[0222] 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.

[0223] In some embodiments of this utility model, such as Figure 16 , Figure 17 and Figure 18 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 16 The terminal block 14 shown is or Figure 19 The electrical control box mounting plate 15 shown in the figure.

[0224] 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.

[0225] In some embodiments of this utility model, such as Figures 16-21 As 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 431 on the left and right sides of the valve island 21, this embodiment facilitates the connection between the vertical plate portions 431 and the horizontal plate portions 432, making the structural arrangement of the third support 43 and the valve island 21 more compact and reasonable.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] 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.

[0230] For example Figure 18 As 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 431. The width direction of the first vertical plate portion 431 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 431 passes through the first vertical plate portion 431 in the front-back direction. The first vertical plate portion 431 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 431. The width direction of the second vertical plate portion 431 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 431 passes through the second vertical plate portion 431 in the left-right direction. The second vertical plate portion 431 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.

[0231] In some embodiments of this utility model, such as Figure 17 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.

[0232] For example Figure 21 As shown, the horizontal plate 432 is a long rectangular plate extending from left to right. The third support 43 includes two vertical plate sections 431, namely the first vertical plate section 431 and the second vertical plate section 431. The first vertical plate section 431 extends vertically and is a long rectangular plate generally perpendicular to the front-back direction. The first vertical plate section 431 is connected to the front edge of the left end of the horizontal plate section 432, and the left edge of the first vertical plate section 431 is flush with the left edge of the horizontal plate section 432. The second vertical plate section 431 extends vertically and is a long rectangular plate perpendicular to the left-back direction. The second vertical plate section 431 is connected to the right edge of the horizontal plate section 432, and the front and rear edges of the second vertical plate section 431 are respectively flush with the front and rear edges of the horizontal plate section 432.

[0233] For example Figure 18As 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.

[0234] 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.

[0235] Reference Figure 27-29 In some embodiments, the structural support includes the chassis 13 of the housing 10, and the connecting bracket 40 includes a fourth bracket 44 connected between the chassis 13 and the valve island 21.

[0236] In this embodiment of the utility model, the valve island 21 is mounted on the chassis 13 by the fourth bracket 44, which further reduces the risk of the valve island 21 coming into contact with condensate and further improves the reliability of the valve island 21.

[0237] Reference Figure 27 , Figure 28 and Figure 29 In some specific embodiments, the fourth support 44 includes at least a first portion 441 extending vertically, the first portion 441 being connected to the bottom wall of the housing 10 and to the valve island 21 to support the valve island 21.

[0238] In this embodiment of the present invention, the fourth bracket 44 includes at least a first portion 441 extending in the vertical direction. The first portion 441 is connected to the bottom wall of the housing 10. The first portion 441 is also connected to the valve island 21 to support the valve island 21, so that the valve island 21 can be spaced apart from the chassis 13 in the vertical direction.

[0239] Reference Figure 27 , Figure 28 and Figure 29 In some specific embodiments, the first part 441 is provided with a first fitting part 443, which fits against the chassis 13 and is fixedly connected to the chassis 13 by fasteners.

[0240] In this embodiment of the present invention, the first part 441 is fixedly connected to the chassis 13 via the first fitting part 443, effectively ensuring the stability of the connection between the first part 441 and the chassis 13. It should be understood that in other embodiments, the first part 441 may also be connected to the chassis 13 by welding, and the present invention does not limit this.

[0241] Reference Figure 28 In some embodiments, the fourth support 44 includes a plurality of first portions 441, the tops of which are connected by a support portion 444, and the valve island 21 is supported on the support portion 444.

[0242] In this embodiment of the utility model, the valve island 21 is supported and fixed by multiple first parts 441, which ensures the stability of the valve island 21 installation.

[0243] Reference Figure 29 and Figure 32 In some embodiments, valve island 21 is located above compressor 50.

[0244] For example, the valve island 21 is disposed inside the housing 10 and above the compressor 50. The vertical projection of the valve island 21 at least partially overlaps with the vertical projection of the compressor 50, which can improve the utilization rate of the space inside the housing 10, thereby reducing the space occupied by the air conditioner 100 and improving the lightweight of the air conditioner 100. Moreover, the valve island 21 is located on the upper side of the compressor 50 and is connected to the compressor 50 through a pipeline, realizing the shortest connection path between the valve island 21 and the compressor 50, further simplifying the structure of the air conditioner 100.

[0245] Reference Figure 29 , Figure 30 and Figure 31 In some embodiments, the fourth support 44 further includes at least a second portion 442 extending in a horizontal direction, the second portion 442 being connected to the housing 10 and to the valve island 21 to support the valve island 21.

[0246] Through the above technical solution, the second part 442 extends horizontally and is connected to the housing 10, which effectively reduces the possibility of the top of the first part 441 shaking, and makes both ends of the fourth bracket 44 connected to the housing 10 in the vertical direction, which effectively improves the stability of the fourth bracket 44.

[0247] Reference Figure 29 , Figure 30 and Figure 31 In some embodiments, the first part 441 and the second part 442 are integral components.

[0248] The above technical solution reduces the difficulty of mold making for the fourth bracket 44, reduces the difficulty of connecting the valve island 21 and the fourth bracket 44, and reduces the cost of the air conditioner 100.

[0249] Reference Figure 29 In some further embodiments, the structural support also includes: a side plate extending vertically from the housing 10, wherein the side plate extending vertically from the housing 10 may be one or more of a left side plate, a right side plate, a front panel, a rear side plate, and a central partition 11.

[0250] In this embodiment of the invention, the first part 441 is connected to the bottom wall of the housing 10, and the second part 442 is connected to the side plate extending vertically from the housing 10. Specifically, the first part 441 can be connected to the bottom wall of the housing 10 by means of connectors or welding, and the second part 442 can be connected to the middle partition 11 by means of connectors or welding. The connectors can be bolts, etc., which are simple in structure, convenient to install, and have low installation cost.

[0251] In some further embodiments, the housing 10 includes a front panel, and the fourth bracket 44 is spaced apart from the front panel, which helps to reduce the vibration amplitude of the front panel.

[0252] Reference Figure 35 , Figure 36 and Figure 37 In some embodiments, the structural support includes a first side plate and a second side plate of the housing 10, the first side plate and the second side plate being arranged adjacent to or spaced apart, the connecting bracket 40 including a fifth bracket 45, the first end of the fifth bracket 45 being fixed to the first side plate, the second end of the fifth bracket 45 being fixed to the second side plate, and the valve island 21 being connected to the fifth bracket 45.

[0253] The side panels of the housing 10 may include: a chassis 13, a front panel, a rear side panel, a left side panel, a right side panel, a top panel, and a partition. The first side panel and the second side panel can be any two of the aforementioned side panels. For example: the first side panel is the left side panel and the second side panel is the right side panel; or, the first side panel is the right side panel and the second side panel is the rear side panel; or, the first side panel is the right side panel and the second side panel is the front panel; or, the first side panel is the right side panel and the second side panel is a partition; or, the first side panel is the chassis 13 and the second side panel is a partition.

[0254] In this embodiment of the invention, the fifth bracket 45 is mounted on the housing 10, and the valve island 21 is connected to the fifth bracket 45. That is, the valve island 21 is mounted on the housing 10 via the fifth bracket 45, ensuring the stability of the valve island 21's installation.

[0255] Reference Figure 37 and Figure 38In some embodiments, the first end of the fifth bracket 45 is provided with a second fitting portion 455, the first fitting portion 443 is fitted with the first side plate and fixedly connected to the first side plate by fasteners; the second end of the fifth bracket 45 is provided with a third fitting portion 456, the third fitting portion 456 is fitted with the second side plate and fixedly connected to the second side plate by fasteners.

[0256] In this embodiment of the invention, the connection between the fifth bracket 45 and the first and second side plates is simple, robust, reliable, and easy to install and disassemble, thus reducing the installation and maintenance costs of the air conditioner 100. In other embodiments, the valve island 21 bracket can also be connected to the first and second side plates by means of snap-fit ​​connection, welding, etc., and this invention does not limit this to such methods.

[0257] In some embodiments, the structural support may include a partition plate 11 disposed within the housing 10, dividing the space within the housing 10 into a compressor chamber and a fan chamber arranged on the left and right. In this embodiment of the present invention, the second side plate is the partition plate 11, the first side plate is disposed opposite to the partition plate, at least a portion of the fifth bracket 45 extends horizontally, and both ends of the fifth bracket 45 are fixedly connected to the partition plate 11 and the first side plate, respectively.

[0258] For example, the first side plate is the right side plate, the second fitting part 455 is fitted to the right side plate and fixedly connected to the right side plate by fasteners, and the third fitting part 456 is fitted to the middle partition plate 11 and fixedly connected to the middle partition plate 11 by fasteners. The fasteners can be screws or bolts.

[0259] In this embodiment of the invention, the fifth bracket 45 extends horizontally, avoiding vertical components (such as the compressor 50), and provides support without occupying vertical height, effectively improving the space utilization of the air conditioner 100 and facilitating its miniaturization. Furthermore, both ends of the fifth bracket 45 are fixedly connected to the partition plate 11 and the housing 10 respectively, providing two-point support and effectively improving the stability of the fifth bracket 45 installation. Since both ends of the fifth bracket 45 are connected to the housing 10, it does not rely on other internal components of the air conditioner 100 (such as the compressor 50), avoiding mutual interference caused by connections with other components.

[0260] In some further embodiments, the housing 10 includes a front panel, and the fifth bracket 45 is spaced apart from the front panel, which helps to reduce the vibration amplitude of the front panel.

[0261] Reference Figure 30 , Figure 31 and Figure 37 In some embodiments, at least a portion of the valve island 21 is integrally formed with the connecting bracket 40.

[0262] In this embodiment of the invention, the valve island 21 and the connecting bracket 40 form a rigid whole. Under vibration or external impact, they will not wobble relative to each other, thus improving the stability of the valve island 21. Furthermore, the material continuity of the integrated component allows stress to be directly transferred from the valve island 21 to the connecting bracket 40, and then dispersed to the housing 10, avoiding the risk of stress fracture. Moreover, the integrated design reduces the number of parts, eliminating the need for screws, clips, and other connecting accessories, naturally eliminating the risk of failure of these components.

[0263] In some further embodiments, the connecting bracket 40 is provided with a hollow area 451, which can achieve structural lightweighting. The hollow area 451 of the one-piece molded structure can be designed according to the stress requirements, which reduces the volume while ensuring strength and is more suitable for the compact space inside the air conditioner 100.

[0264] In some embodiments, the valve island 21 includes a first raft plate 217, which includes two support plates, namely an upper valve island 215 and a lower valve island 216. The upper valve island 215 and / or the lower valve island 216 define a refrigerant flow channel. The connecting bracket 40 is integrally formed with one of the upper valve island 215 and the lower valve island 216. In this embodiment of the present invention, the valve island 21 and the connecting bracket 40 have simple structures, reducing the difficulty of mold making and reducing the cost of the air conditioner 100.

[0265] The valve island upper plate 215 and / or valve island lower plate 216 define the refrigerant flow path. This can be achieved by the valve island upper plate 215 defining the refrigerant flow path alone, or by the valve island lower plate 216 defining the refrigerant flow path alone, or by the valve island upper plate 215 and valve island lower plate 216 defining the refrigerant flow path separately, or by the valve island upper plate 215 and valve island lower plate 216 working together to define the refrigerant flow path. This application does not impose any restrictions on this.

[0266] Reference Figure 38 and Figure 39 In other embodiments, the valve island 21 and the connecting bracket 40 can also be separate components, with the connecting bracket 40 having a support surface 453, and at least a portion of the valve island 21 being supported on the support surface 453.

[0267] In this embodiment of the utility model, the valve island 21 and the connecting bracket 40 are designed as separate units. Minor tolerances are inevitable in the processing and assembly of the valve island 21 and the connecting bracket 40 (such as dimensional deviations of the valve island 21 and flatness errors of the supporting surface 453 of the connecting bracket 40). The separate design can offset the influence of these tolerances through structural characteristics, allowing for slight positional adjustments. When the valve island 21 is placed on the supporting surface 453, fine adjustments can be made through the contact area of ​​the supporting surface 453. For example, when the plate heat exchanger part 2172 or the valve body part 2171 on the valve island 21 is connected to the pipeline, if there is a slight misalignment, the valve island 21 can be slightly slid on the supporting surface 453 to adjust it into place before fixing the valve island 21 and the connecting bracket 40 with screws 454, avoiding the difficulty of connection caused by a completely fixed position of the integrated component. If valve island 21 malfunctions, there is no need to disassemble or replace connecting bracket 40. Simply remove screw 454 and take the old valve island 21 off from support surface 453. Similarly, if the support surface 453 of connecting bracket 40 is deformed, only connecting bracket 40 needs to be replaced. There is no need to replace the intact valve island 21, which can significantly reduce maintenance costs.

[0268] In some specific embodiments, the valve island 21 can be screwed or riveted to the connecting bracket 40, which simplifies the connection method, facilitates assembly, and reduces the cost of the air conditioner 100. In other embodiments, the valve island 21 can also be snapped together with the connecting bracket 40, welded, etc., and this utility model does not limit this.

[0269] In some of the above embodiments, the valve island 21 is directly mounted on the structural support. In other embodiments, the valve island 21 is mounted on the structural support via a connecting bracket 40. In still other embodiments, the valve island 21 can be mounted on the structural support via a functional component. Mounting the valve island 21 via a functional component simplifies the structure of the air conditioner 100 and reduces its cost.

[0270] In some embodiments, the valve island 21 is positioned and mounted on the structural support member by functional components. The functional components used for positioning and mounting the valve island 21 include at least one of a plate heat exchanger 63, a gas-liquid separator 30, and an oil-liquid separator 65. This invention does not limit the scope to any component that can be used to mount the valve island 21.

[0271] Reference Figure 40 In some embodiments of this utility model, the structural support includes the chassis 13 of the housing 10, and the functional components include: a gas-liquid separator 30, which is disposed inside the housing 10 and mounted on the chassis 13, and a valve island 21 is fixedly connected to the gas-liquid separator 30. In other words, the valve island 21 is fixedly supported by the gas-liquid separator 30.

[0272] 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 the valve island 21 and the gas-liquid separator 30 can be fastened together 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 bracket. The valve island 21 and the bracket can be welded, bolted, snap-fitted, and / or riveted together, and the bracket and the gas-liquid separator 30 can be welded, bolted, snap-fitted, and / or riveted together. 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.

[0273] In some embodiments, the valve island 21 may also be positioned and installed on the structural support by a functional component, and the functional component positioned and installed on the structural support is fixedly supported by a connecting pipe and communicated with the refrigerant flow channel through the connecting pipe.

[0274] For example, the structural support includes the chassis 13 of the housing 10, the gas-liquid separator 30 is disposed inside the housing 10 and installed on the chassis 13, the refrigerant flow channel of the valve island 21 is connected to the gas-liquid separator 30 through a connecting pipe, and the valve island 21 is fixedly supported on the gas-liquid separator 30 through the connecting pipe.

[0275] In this embodiment, the functional component is fixedly connected to the valve island via a connecting pipe and communicates with the refrigerant flow channel, effectively simplifying the structure of the air conditioner and helping to reduce the cost of the air conditioner 100. It should be understood that in some other embodiments, the valve island can also be directly positioned and installed on the structural support member via at least one connecting pipe, as long as it can be used to fix the valve island, this application does not limit this.

[0276] Reference Figure 41 In some embodiments, the air conditioner 100 further includes a fixing bracket 80, which is used to fix the functional components of the fixing valve island 21 to the structural support.

[0277] The above technical solution effectively improves the stability of the functional components used to fix the valve island 21 and enhances the reliability of the valve island 21.

[0278] Reference Figure 41 , Figure 42 and Figure 43 In some embodiments of this utility model, the functional components for fixing the valve island 21 include a gas-liquid separator 30, and the valve island 21 is fixed to the top of the gas-liquid separator 30; the fixing bracket 80 includes a sixth bracket 81, which is connected to the upper part of the gas-liquid separator 30 and the structural support member respectively.

[0279] Understandably, by setting the gas-liquid separator 30 as a functional component for fixing the valve island 21, more installation space can be reserved for the valve island 21, reducing the installation difficulty of the valve island 21. Furthermore, by connecting the sixth bracket 81 to the upper part of the gas-liquid separator 30, the support effect of the sixth bracket 81 can be improved, thereby enhancing the stability of the gas-liquid separator 30.

[0280] It should be noted that the valve island 21 can be directly attached to the outer wall of the gas-liquid separator 30, which can improve space utilization and eliminate the need for connecting pipes between the valve island 21 and the gas-liquid separator 30, thus simplifying the structure and reducing costs; alternatively, the valve island 21 can be arranged separately from the outer wall of the gas-liquid separator 30, which can reduce the installation difficulty of the valve island 21 and prevent the valve island 21 and the gas-liquid separator 30 from squeezing each other, thereby improving the installation stability of the valve island 21.

[0281] In some embodiments of this utility model, such as Figure 43 and Figure 44 As shown, the sixth bracket 81 can be placed at the top of the gas-liquid separator 30. This makes it easier to position and connect the sixth bracket 81 with the gas-liquid separator 30, improves the installation accuracy of the sixth bracket 81, enhances the support effect of the sixth bracket 81 on the gas-liquid separator 30, improves the stability of the valve island 21, and allows for more space to be reserved for the sixth bracket 81, thus improving the design rationality of the air conditioner 100.

[0282] In some embodiments of this utility model, such as Figure 44 As shown, an external pipe 31 can be connected to the top of the gas-liquid separator 30. The connecting pipe is used to communicate with related components. The sixth bracket 81 is supported at the top of the gas-liquid separator 30 and connected to the external pipe 31. This can improve the connection stability between the sixth bracket 81 and the gas-liquid separator 30, which is beneficial to improving the stability of the valve island 21.

[0283] In some embodiments of this utility model, such as Figure 44 As shown, the external connector 31 includes a first external connector 32 and a second external connector 33, which are spaced apart. The first external connector 32 is connected to a corresponding fluid channel, and the second external connector 33 is connected to a related component. The sixth support 81 is connected to the second external connector 33. Therefore, when the sixth support 81 vibrates, the interference of the sixth support 81 on the valve island 21 can be reduced, thus improving the stability of the valve island 21.

[0284] Reference Figure 44 and Figure 45In some embodiments of this utility model, the sixth bracket 81 includes a main body 811 and a limiting part 813. The limiting part 813 is connected to the main body 811 and protrudes from the side of the main body 811 facing the gas-liquid separator 30. The main body 811 is provided with a limiting groove 812. The sixth bracket 81 has an installation position. In the installation position, the limiting part 813 is limited and engaged with the outer peripheral wall of the gas-liquid separator 30 along the first direction F1. The outer pipe 31 is snapped into the limiting groove 812 and the main body 811 is limited and engaged with the outer pipe 31 along the second direction F2. The first direction F1 and the second direction F2 are opposite directions.

[0285] For example, refer to Figures 44-45 As shown, the sixth support 81 includes a main body 811 and a limiting part 813. The main body 811 is plate-shaped and is attached to the top of the gas-liquid separator 30. The limiting part 813 is connected to the main body 811 and protrudes from the side of the main body 811 facing the gas-liquid separator 30. The main body 811 is provided with a limiting groove 812, which is matched with the outer pipe 31.

[0286] The sixth bracket 81 has an installation position. In the installation position, the limiting part 813 is limited and engaged with the outer peripheral wall of the gas-liquid separator 30 along the first direction F1, and the outer pipe 31 is snapped into the limiting groove 812. The main body 811 can be limited and engaged with the outer pipe 31 located in the limiting groove 812 along the second direction F2. The first direction F1 and the second direction F2 are opposite directions, so that the sixth bracket 81 can be snapped between the gas-liquid separator 30 and the outer pipe 31.

[0287] The above settings reduce the difficulty of disassembling and assembling the sixth bracket 81, facilitate subsequent maintenance, improve the practicality of the air conditioner 100, enhance the installation stability of the sixth bracket 81, and improve the support effect of the sixth bracket 81 on the gas-liquid separator 30.

[0288] In some embodiments of this utility model, such as Figure 45 As shown, the sixth bracket 81 further includes a connecting portion 814, which is connected to one side of the main body 811 along the first direction F1 or the second direction F2. The connecting portion 814 is used to connect to the housing 10. For example, the connecting portion 814 can be connected to one side of the main body 811 along the first direction F1; or, the connecting portion 814 can be connected to one side of the main body 811 along the second direction F2.

[0289] By setting the above, the limiting direction of the sixth bracket 81 can be kept consistent with the vibration transmission direction, which can prevent the sixth bracket 81 from becoming loose due to vibration and improve the installation stability of the sixth bracket 81.

[0290] In some embodiments of this utility model, such as Figures 43-45 As shown, the connecting part 814 can be provided to protrude from the side of the main body 811 away from the gas-liquid separator 30, so that the connecting part 814 and the limiting part 813 are respectively located on both sides of the main body 811 in the vertical direction. This makes the structure of the sixth bracket 81 more uniform, improves the structural strength of the sixth bracket 81, enhances the installation stability of the sixth bracket 81, and improves the design rationality of the sixth bracket 81.

[0291] In some embodiments of this utility model, such as Figure 45 As shown, the limiting groove 812 can be provided, including an inlet section 8121 and a snap-fit ​​section 8123 that are bent and connected. In the installation position, the outer pipe 31 extends into the snap-fit ​​section 8123 through the inlet section 8121 to engage with the inner wall of the snap-fit ​​section 8123 for limiting.

[0292] The above settings prevent vibration from causing the outer pipe 31 to disengage from the limiting groove 812, improve the installation stability of the sixth bracket 81, thereby ensuring the supporting effect of the sixth bracket 81 on the gas-liquid separator 30 and improving the reliability of the air conditioner 100.

[0293] In some embodiments of this utility model, such as Figure 45 As shown, the limiting groove 812 also includes a transition section 8122, which is arc-shaped and used to connect the inlet section 8121 and the snap-fit ​​section 8123. This makes it easier for the outer pipe 31 to snap into the snap-fit ​​section 8123, reducing the installation difficulty of the sixth bracket 81 and improving the design rationality of the sixth bracket 81.

[0294] In some embodiments of this utility model, such as Figure 46 As shown, the sixth bracket 81 can be connected to the outer peripheral wall of the gas-liquid separator 30, and the end of the sixth bracket 81 facing away from the gas-liquid separator 30 is used to connect to the housing 10 and / or the components fixed to the housing 10.

[0295] For example, the sixth bracket 81 can be welded to the outer peripheral wall of the gas-liquid separator 30; or, a snap-fit ​​structure can be provided on the outer peripheral wall of the gas-liquid separator 30, and the sixth bracket 81 can be snap-fitted to the snap-fit ​​structure; or, a threaded hole can be provided on the outer peripheral wall of the gas-liquid separator 30, and a connecting through hole can be provided on the sixth bracket 81, with a screw threaded through the connecting through hole and screwed to the threaded hole; or, the sixth bracket 81 can be fixed to the outer peripheral wall of the gas-liquid separator 30 by rivets, and the present invention does not limit this.

[0296] The above settings can maintain a sufficient distance between the sixth bracket 81 and the valve island 21, which helps to prevent the sixth bracket 81 from contacting the valve island 21 during vibration and improves the installation stability of the valve island 21.

[0297] In some embodiments of this utility model, such as Figure 45 As shown, the sixth bracket 81 is provided with a connecting screw hole 8141, and a screw connector passes through the connecting screw hole 8141 to be detachably connected to the housing 10 and / or the component fixed to the housing 10. This reduces the difficulty of assembling and disassembling the sixth bracket 81, making the air conditioner 100 easier to maintain and improving the practicality of the air conditioner 100.

[0298] In some embodiments of this utility model, such as Figure 47 and Figure 48 As shown, a heat exchanger is installed inside the fan cavity, and the heat exchanger is positioned opposite the air outlet side of the outdoor fan so that the airflow blown out by the outdoor fan can exchange heat with the heat exchanger. The heat exchanger is fixedly connected to the housing 10 and has a heat exchanger side plate 12. The heat exchanger side plate 12 extends into the compressor 50 cavity and is connected to the compressor 50 through the valve island 21, allowing refrigerant to flow into or out of the heat exchanger through the heat exchanger side plate 12. A sixth bracket 81 can be connected to the heat exchanger side plate 12 so that the heat exchanger can support the gas-liquid separator 30.

[0299] With the above configuration, the sixth bracket 81 can transmit vibration to the outside of the compressor 50 cavity, which helps to reduce the impact of vibration on the valve island 21 and improves the stability of the air conditioner 100.

[0300] like Figure 32 , Figure 33 and Figure 34 As shown in some embodiments of this utility model, the air conditioner 100 further 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 circulating refrigerant.

[0301] 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.

[0302] Reference Figure 30 and Figure 31 In some embodiments, the valve island 21 includes a first raft plate 217, which has a first face a and a second face b facing away from each other. The first face a has a plurality of valve body connectors 2171 for connecting valve bodies, and the second face b has a plate heat exchanger connector 2172, which defines at least one valve island interface 211 for connecting a plate heat exchanger 63.

[0303] In some examples, such as Figure 32 , Figure 33 and Figure 34 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 plate heat exchanger support 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.

[0304] like Figure 32 , Figure 33 and Figure 34 As shown, in some embodiments, the air conditioner 100 further includes: a gas-liquid separator 30, a plate heat exchanger 63, and a plate heat exchanger support 70; wherein, the gas-liquid separator 30 is installed inside the housing 10 and connected to the refrigerant flow channel; the valve island 21 is provided with a plate heat exchanger connector 2172, and the plate heat exchanger 63 is disposed on the valve island 21 through the plate heat exchanger connector 2172 and communicates with the refrigerant flow channel. The plate heat exchanger support 70 is installed and supported on the gas-liquid separator 30, and the plate heat exchanger 63 is supported above the plate heat exchanger support 70.

[0305] For example, the gas-liquid separator 30 is fixedly installed on the bottom wall of the housing 10 and extends in the vertical direction. The plate heat exchanger support 70 is installed and supported on the top of the gas-liquid separator 30, and the plate heat exchanger 63 is supported above the plate heat exchanger support 70.

[0306] It should be noted that the gas-liquid separator 30 is connected to the refrigerant flow channel of the valve island 21. This connection can be achieved by the gas-liquid separator 30 being directly connected to the refrigerant flow channel through its own inlet pipe and / or outlet pipe, or by the gas-liquid separator 30 being indirectly connected to the refrigerant flow channel of the valve island 21 through pipes or other components. This utility model does not impose any limitations on this connection.

[0307] The plate heat exchanger 63 is mounted on the valve island 21 via the plate heat exchanger joint 2172 and is connected to the refrigerant flow channel. The plate heat exchanger 63 is relatively heavy; therefore, it is supported by the plate heat exchanger support member 70, which effectively improves its stability and reduces the possibility of connection failure between the plate heat exchanger 63 and the valve island 21. Furthermore, the plate heat exchanger support member 70 supports the gas-liquid separator 30, which simplifies its structure and reduces the cost of the air conditioner 100.

[0308] like Figure 32 , Figure 33 and Figure 34As shown, in some specific embodiments, the plate heat exchanger support 70 includes a first sub-plate 71, a connecting plate 72, and a second sub-plate 73. The connecting plate 72 extends vertically, and the first sub-plate 71 and the second sub-plate 73 both extend horizontally and are connected to the upper and lower ends of the connecting plate 72. The first sub-plate 71 and the second sub-plate 73 are located on different sides of the connecting plate 72. The first sub-plate 71 is supported on the top surface of the gas-liquid separator 30, and the plate heat exchanger 63 is supported above the second sub-plate 73.

[0309] Specifically, the connecting plate 72 is bent and connected between the first sub-plate 71 and the second sub-plate 73. The first sub-plate 71 is configured to extend horizontally, the second sub-plate 73 is also configured to extend horizontally, and the connecting plate 72 is configured to extend vertically, so that the first sub-plate 71 and the second sub-plate 73 can be vertically connected to the upper and lower ends of the connecting plate 72 respectively. The first sub-plate 71 is connected to the top surface of the gas-liquid separator 30, and the top surface of the gas-liquid separator 30 is also configured to extend horizontally, so that the first sub-plate 71 can be closely connected to the top surface of the gas-liquid separator 30, thereby improving the reliability of the gas-liquid separator 30 in supporting the first sub-plate 71, so as to ensure the installation reliability of the plate heat exchanger support 70.

[0310] Furthermore, the gas-liquid separator 30 can be configured as a columnar structure, that is, the side wall of the gas-liquid separator 30 can be set perpendicular to the top surface, so that when the first sub-plate 71 is connected to the top surface of the gas-liquid separator 30, the side wall of the gas-liquid separator 30 can support the connecting plate 72, thereby dispersing the force on the plate heat exchanger support 70 and improving the reliability of the plate heat exchanger support 70.

[0311] In addition, the second sub-plate 73 also extends horizontally, and the first sub-plate 71 and the second sub-plate 73 are located on different sides of the connecting plate 72, that is, the second sub-plate 73 extends away from the gas-liquid separator 30, so that the installation area of ​​the plate heat exchanger 63 can be defined between the second sub-plate 73, the connecting plate 72 and the valve island 21, and the bottom of the plate heat exchanger 63 can contact the second sub-plate 73 to ensure the reliability of the support for the plate heat exchanger 63, and reduce the force on the bottom of the plate heat exchanger support 70, thus ensuring the installation reliability of the plate heat exchanger support 70.

[0312] like Figure 32 , Figure 33 and Figure 34 As shown, in some embodiments, the second subplate 73 has a first limiting flange 731 on the side edge away from the connecting plate 72. The first limiting flange 731 is bent upward and distributed opposite to the connecting plate 72. The first limiting flange 731 is used to limit the engagement with the plate heat exchanger 63.

[0313] Specifically, one side of the second sub-plate 73 is connected to the connecting plate 72, and the other side extends away from the connecting plate 72. A first limiting flange 731 is formed on the side of the second sub-plate 73 away from the connecting plate 72. The first limiting flange 731 extends upward on the side of the second sub-plate 73 away from the connecting plate 72. The first limiting flange 731 and the connecting plate 72 are relatively distributed, so that the first limiting flange 731 and the connecting plate 72 can limit the plate heat exchanger 63, thereby improving the installation accuracy. It can also limit the plate heat exchanger 63 in the horizontal direction, thereby improving the reliability of the connection between the plate heat exchanger 63 and the plate heat exchanger support 70.

[0314] Reference Figures 49-52 In other embodiments, the functional components for fixing the valve island 21 include a plate heat exchanger 63, which has multiple plate heat exchanger ports, at least one of which is fixedly connected to the valve island 21 and communicates with a corresponding refrigerant flow channel. The fixing bracket 80 includes a seventh bracket 82, which is connected to both the plate heat exchanger 63 and the structural support member.

[0315] Specifically, the plate heat exchanger 63 can be installed on one side of the valve island 21. The plate heat exchanger 63 is provided with multiple plate heat exchanger interfaces, and at least one plate heat exchanger interface is fixed and connected to the corresponding valve island interface 211. This allows the refrigerant flowing in the valve island 21 to enter the plate heat exchanger 63 for heat exchange through the valve island interface 211, or the refrigerant after heat exchange can flow from the plate heat exchanger 63 into the valve island 21.

[0316] When the plate heat exchanger interface is connected to the valve island interface 211 on the valve island 21, the connection between the two interfaces is realized, and the valve island 21 is fixed on the plate heat exchanger 63. The assembly operation of fixing the valve island 21 on the plate heat exchanger 63 is convenient and efficient. At the same time, the plate heat exchanger 63 and the compressor 50 usually do not have a direct rigid connection. The vibration generated by the compressor 50 during operation has little impact on the plate heat exchanger 63. Therefore, the stability of the valve island 21 fixed on the plate heat exchanger 63 is good, and the plate heat exchanger 63 can suppress the vibration of the valve island 21.

[0317] In some embodiments of this utility model, reference is made to Figure 51 and Figure 52 As shown, the plate heat exchanger 63 has four plate heat exchanger interfaces on the side facing the valve island 21. The four plate heat exchanger interfaces are located at the four vertices of the rectangle. A protruding valve block 23 is formed on one side surface of the valve island 21. The valve block 23 has four valve island interfaces 211. The four valve island interfaces 211 on the valve block 23 are located at the four vertices of the rectangle and are respectively connected to the corresponding plate heat exchanger interfaces.

[0318] Specifically, the four plate heat exchanger interfaces on the plate heat exchanger 63 are arranged in a rectangular pattern, and the four valve island interfaces 211 on the valve block 23 of the valve island 21 are also arranged in a corresponding rectangular pattern. This standardized interface layout design makes the connection between the two more efficient and accurate. The rectangular arrangement helps ensure that each interface can be precisely aligned with the corresponding valve island interface 211, reducing connection problems caused by interface misalignment. Furthermore, the plate heat exchanger 63 and the valve island 21 are connected by four interfaces with rectangular vertices distributed apart, making the connection simple, reliable, and with strong load-bearing capacity. This improves the support and fixation effect of the plate heat exchanger 63 on the valve island 21, enhancing the reliability and stability of the valve island 21 assembly. In addition, because the plate heat exchanger interface layout is standardized and corresponds one-to-one with the valve island interfaces 211, installers can complete the operation more quickly and accurately when connecting the plate heat exchanger 63 and the valve block 23, reducing the error rate during installation, shortening the commissioning time, and improving the overall installation efficiency.

[0319] In some embodiments, of the four plate heat exchanger interfaces on the plate heat exchanger 63, two may be interconnected and the other two may also be interconnected. That is, two refrigerant flow paths, a first refrigerant flow path and a second refrigerant flow path, may be formed inside the plate heat exchanger 63, and the refrigerant in the two refrigerant flow paths may exchange heat inside the plate heat exchanger 63.

[0320] In other embodiments, more flow channels may be formed within the plate heat exchanger 63.

[0321] It should be noted that a protruding valve block 23 is provided on the surface of the valve island 21. The protruding design of the valve block 23 enhances the overall structural stability of the valve island 21 assembly. Multiple valve island interfaces 211 can be formed on the side wall of the valve block 23. The valve island interfaces 211 are concentrated on the side wall of the valve block 23, making the layout of the valve island interfaces 211 on the valve island 21 assembly more compact. The plate heat exchanger 63 is connected to the side wall of the valve block 23. Therefore, the plate heat exchanger 63 can support and restrict the valve block 23 on one side surface of the valve island 21, preventing the valve island 21 from shaking or shifting on the plate heat exchanger 63. The plate heat exchanger 63 is provided with multiple plate heat exchanger interfaces, and each plate heat exchanger interface corresponds to and is connected to a valve island interface 211, realizing the connection between the plate heat exchanger 63 and the valve island 21. This allows the refrigerant to flow between the plate heat exchanger 63 and the valve island 21, facilitating the refrigerant to flow from the valve island 21 into the plate heat exchanger 63 for heat exchange or to flow back to the valve island 21 after heat exchange in the plate heat exchanger 63. By setting the plate heat exchanger 63 on the side wall of the valve block 23 and connecting the plate heat exchanger interfaces to multiple valve island interfaces 211, a direct and efficient connection between the interfaces is achieved, reducing the use of intermediate piping structures, lowering the resistance to refrigerant flow, and improving the system's operating efficiency. The protruding valve block 23 design allows the plate heat exchanger 63 to fit more tightly onto the valve island 21, making full use of the space on the side of the valve island 21, resulting in a more compact overall layout of the air conditioner 100 system and achieving miniaturization of the air conditioner 100 system.

[0322] In some embodiments of this utility model, at least one connecting platform extending to the plate heat exchanger 63 is formed on the valve island 21.

[0323] Specifically, the connecting platform can extend to the plate heat exchanger 63. The connecting platform increases the contact area between the valve island 21 and the plate heat exchanger 63, making it easier to position and fix the valve island 21 when installed on the plate heat exchanger 63. Furthermore, the connecting platform effectively distributes the weight of the valve island 21, the stress generated during operation, and the pulsating impact of refrigerant flow, ensuring the stability of the valve island 21 and thus improving the reliability and service life of the entire valve island 21 assembly. The plate heat exchanger 63 can provide better support and fixation for the valve island 21 through the connecting platform, allowing the valve island 21 assembly to maintain a more stable state during operation. This reduces problems such as loosening of interfaces and leakage caused by vibration or shaking, improving the overall operational stability and reliability of the system.

[0324] It should be noted that the number of connecting platforms can be one or more. For example, when there is one connecting platform, it can extend to one side of the plate heat exchanger 63 to increase the contact area between the valve island 21 and the plate heat exchanger 63, thereby improving the stability of the connection between the two. Alternatively, when there are multiple connecting platforms, at least two connecting platforms can extend to opposite sides of the plate heat exchanger 63. The valve island 21 can be clamped and fixed to the plate heat exchanger 63 by multiple connecting platforms, further improving the stability and reliability of the connection between the valve island 21 and the plate heat exchanger 63.

[0325] Reference Figure 50 In some embodiments of this utility model, one end of the seventh bracket 82 is fixedly connected to the plate heat exchanger 63, and the other end of the seventh bracket 82 is fixedly connected to the structural support member.

[0326] The structural support can be a partition plate 11, and the seventh bracket 82 is fixed on the partition plate 11. The vibration generated by the compressor 50 is not easily transmitted to the partition plate 11, so as to improve the stability of the valve island 21 assembly.

[0327] The partition plate 11 may be provided with screw holes, limiting slots and other structures for connecting with the seventh bracket 82. The seventh bracket 82 is provided with screw holes, limiting slots and other structures for corresponding connection with the partition plate 11 and the plate heat exchanger 63. The plate heat exchanger 63 is provided with screw holes, limiting slots and other structures corresponding to the seventh bracket 82. The seventh bracket 82 is connected between the partition plate 11 and the plate heat exchanger 63. The seventh bracket 82 can be connected to the partition plate 11 and the plate heat exchanger 63 on both sides by fasteners such as screws 454 and rivets, or by snap-fit.

[0328] It should be noted that the valve island can be connected to the structural support through a connecting bracket, and also to the structural support through functional components; this application does not impose any restrictions on this.
