[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The air conditioner 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0040] like Figures 1-5 As shown, the air conditioner 1 according to an embodiment of the present utility model includes a housing 10, a valve island 20, and a valve plate 40.

[0041] The housing 10 defines a receiving cavity, and the valve island 20 is disposed in the receiving cavity. The valve island 20 includes a body part 21, and the body part 21 is provided with multiple fluid channels. The multiple fluid channels are suitable for connecting multiple refrigerant components in the air conditioner 1, thereby forming a refrigerant system and realizing the circulation of refrigerant in the refrigerant system.

[0042] The air conditioner 1 includes a refrigerant system and a piping system 80. The piping system 80 is located inside the casing 10, and the refrigerant system includes multiple refrigerant components. The main body 21 has multiple fluid channels, and the refrigerant components are connected to the fluid channels through the piping system 80.

[0043] Specifically, the main body 21 is provided with multiple valve island interfaces 211. One end of the pipeline system 80 is connected to the valve island interface 211, and the other end is connected to the refrigerant component to realize the connection between the refrigerant component and the fluid channel. In turn, multiple fluid channels are used to connect multiple refrigerant components, so that the refrigerant can circulate among multiple refrigerant components.

[0044] In some embodiments, on / off valves are provided between the piping system 80 and the valve island interface 211, and between the piping system 80 and the refrigerant components. The on / off valves include, but are not limited to, four-way valves 91, electronic expansion valves 92, single-way solenoid valves 93, and shut-off valves, etc. No further restrictions are imposed here.

[0045] In some embodiments, multiple refrigerant components include a compressor 34, an electronic expansion valve 92, an indoor heat exchanger, an outdoor heat exchanger, a gas-liquid separator 31, etc.

[0046] For example, the first fluid channel connects the compressor 34 and the outdoor heat exchanger, the second fluid channel connects the gas-liquid separator 31 and the outdoor heat exchanger, the third fluid channel connects the indoor heat exchanger and the electronic expansion valve 92, and the fourth fluid channel connects the electronic expansion valve 92 and the indoor heat exchanger, etc., without further restrictions.

[0047] In some examples, the compressor is connected to the oil separator 32, and the first fluid passage connects the oil separator 32 and the outdoor heat exchanger.

[0048] Specifically, valve island 20 is an integrated component in air conditioner 1. Valve island 20 can be simply understood as integrating conventional piping in traditional air conditioner 1 into a single structure. Valve island interface 211 on body 21 is equivalent to a piping structure in traditional air conditioner 1. Multiple different valve island interfaces 211 are integrated on body 21 to connect each valve island interface 211 using fluid channels within body 21, allowing refrigerant to circulate within the refrigerant system through the fluid channels.

[0049] This reduces the space occupied by pipe connections in traditional air conditioner 1, which can reduce pipe length, lower costs and space occupation, reduce pipe resistance and pressure loss, and realize the integrated layout of the pipe system 80. At the same time, it can avoid interference with the assembly of other structures in air conditioner 1. The integrated design makes the overall structure of air conditioner 1 more compact.

[0050] Meanwhile, during the manufacturing of air conditioner 1, leakage detection of the refrigerant system is required. In traditional air conditioners, the refrigerant components are welded to the pipes to achieve communication between the corresponding refrigerant components. Leakage detection can only be performed after the air conditioner is fully assembled. In this embodiment, the refrigerant components are connected to the valve island interface 211 of the valve island 20 through the pipe system 80, thereby achieving communication between the corresponding refrigerant components. On the one hand, the welding process is concentrated at the valve island 20. On the other hand, leakage detection can be performed after the refrigerant components and valve island 20 are pre-assembled, saving the assembly welding time and weld points of air conditioner 1 and reducing the probability of leakage at the assembly weld points.

[0051] The valve plate 40 is located in the receiving cavity and is fixed to the housing 10. The valve island 20 is supported on the valve plate 40 so that the valve island 20 is positioned by the valve plate 40 and the position of the valve island 20 is supported. This allows the valve island 20 to be fixed in the receiving cavity, reducing the possibility of the valve island 20 shaking and improving the stability of the valve island 20 installation.

[0052] Specifically, if the valve island 20 is fixed in position solely by its connection to the piping system 80, it is prone to shaking within the housing cavity when the air conditioner 1 vibrates, which could easily cause the piping system 80 to break. To address this issue, this embodiment provides a valve plate 40 to support the valve island 20, thereby improving the stability of the valve island 20 installation and reducing the frequency and amplitude of shaking.

[0053] Therefore, according to the embodiment of the present utility model, the air conditioner 1, by setting the valve island 20, can reduce the length of the pipeline, reduce the cost, reduce the space occupation, and can realize the pre-installation and leak detection of the pipeline system 80, which is conducive to reducing the probability of weld point leakage. Furthermore, by setting the valve plate 40, the valve island 20 can be positioned, which facilitates the improvement of the installation stability of the valve island 20.

[0054] The air conditioner 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0055] In some specific embodiments of this utility model, such as Figures 1-5 As shown, the air conditioner 1 includes a housing 10, a valve island 20, and a valve plate 40.

[0056] In some embodiments of this utility model, the air conditioner further includes a gas-liquid separator 31, which is disposed in the receiving cavity and is connected to a corresponding fluid channel to connect the gas-liquid separator 31 with other refrigerant components, such as connecting the compressor 34 and the gas-liquid separator 31.

[0057] In some embodiments, the body 21 and the gas-liquid separator 31 are separately disposed so as to prevent the gas-liquid separator 31 from causing the valve island 20 to shake when it shakes.

[0058] It should be noted that the air conditioner 1 will vibrate during operation. Meanwhile, the gas-liquid separator 31 is a relatively tall structural component, and it is prone to swaying within the housing cavity. Therefore, separating the main body 21 from the gas-liquid separator 31 prevents the swaying of the gas-liquid separator 31 from being transmitted to the main body 21, and prevents the gas-liquid separator 31 from causing the valve island 20 to sway, affecting the stable connection between the valve island 20 and the refrigerant components and piping system 80, and preventing the piping system 80 from breaking.

[0059] In some examples, the main body 21 and the gas-liquid separator 31 are connected by a pipeline. The gas-liquid separator 31 can support the main body 21 through the pipeline, thereby balancing the vibration of the valve island 20 and improving the stability and reliability of the valve island 20.

[0060] Meanwhile, the pipeline has a certain degree of flexibility and deformability. When the gas-liquid separator 31 shakes, the shaking at the pipeline is not easily transmitted to the main body 21. This reduces the possibility that the gas-liquid separator 31 will cause the valve island 20 to shake, and facilitates the stable connection between the valve island 20 and the refrigerant components and pipeline system 80.

[0061] In other embodiments, the body 21 is supported on the gas-liquid separator 31 so that the housing 10 and the valve plate 40 together support the position of the valve island 20, thereby improving the stability and reliability of the valve island 20.

[0062] In some embodiments, the body 21 is directly supported on the gas-liquid separator 31.

[0063] In other embodiments, a support is provided between the body 21 and the gas-liquid separator 31, with the side of the support facing the gas-liquid separator 31 connected to the gas-liquid separator 31 and the side of the support facing the body 21 connected to the body 21, so as to support the valve island 20 on the gas-liquid separator 31.

[0064] The use of a bracket to connect the main body 21 and the gas-liquid separator 31 reduces the difficulty of connecting the main body 21 and the gas-liquid separator 31, and also enhances the reliability of the connection between the main body 21 and the gas-liquid separator 31.

[0065] In some embodiments of this utility model, such as Figure 1 , Figure 2As shown, the housing 10 includes a housing 101 and a partition 102. The housing 101 has a receiving cavity, and the partition 102 is disposed in the receiving cavity. The partition 102 divides the receiving cavity into a first chamber 11 and a second chamber 12. The valve island 20 is disposed in the first chamber 11, and the valve plate 40 is located in the first chamber 11. The two ends of the valve plate 40 are respectively fixed to the partition 102 and the side panel 103 of the housing 101 to fix the valve plate 40 in the first chamber 11 and limit the position of the valve plate 40 so that the valve plate 40 can stably support the position of the valve island 20.

[0066] Specifically, when the air conditioner 1 is working, air will flow in the second chamber 12. Therefore, the valve plate 40 and the valve island 20 are set in the first chamber 112. The chamber used for air flow and the chamber where the valve island 40 is located are different chambers to avoid the air causing the piping system 80 in the first chamber 112 to shake. This improves the stability of the connection between the main body 21 and the piping system 80 and reduces the possibility of the piping system 80 breaking.

[0067] In some embodiments, an outdoor heat exchanger and an outdoor fan are disposed in a second chamber 12. The outdoor fan is used to drive air from the environment into the second chamber 12 so that the air can exchange heat with the outdoor heat exchanger in the second chamber 12, thereby enabling the refrigerant in the outdoor heat exchanger to absorb heat from the air or dissipate heat from the refrigerant into the air.

[0068] In some optional embodiments of this utility model, such as Figure 6 , Figure 7 As shown, the valve plate 40 includes a first support portion 401 and a second support portion 402. The first support portion 401 extends in a vertical direction, and both ends of the first support portion 401 are fixed to the partition plate 102 and the side panel 103, respectively, so as to fix the valve plate 40 in the first chamber 11.

[0069] The second support part 402 is connected to the first support part 401. The second support part 402 extends in the horizontal direction. The valve island 20 is supported on the second support part 402 so that the valve plate 40 has sufficient area to contact and cooperate with the valve island 20, thereby supporting the position of the valve island 20, reducing the possibility of the valve island 20 shaking, and facilitating the reduction of the shaking frequency and amplitude of the valve island 20.

[0070] In some embodiments, such as Figure 2 , Figure 7 As shown, both the partition 102 and the side panel 103 extend in the front-to-back direction to divide the accommodating cavity into a first chamber 11 and a second chamber 12 in the left-to-right direction. The front end of the partition 102 has a first connecting flange 1021 extending in the left-to-right direction. The left and right ends of the first support 401 are respectively connected to the first connecting flange 1021 and the side panel 103.

[0071] The first support portion 401 extends along the left-right direction in its length direction, and its left end is connected to the first connecting flange 1021. The right end of the first support portion 401 has a second connecting flange 4012, which extends along the front-back direction and is connected to the side panel 103.

[0072] Furthermore, the right end of the first connecting flange 1021 and the first support portion 401 are fixed together by welding, bolts, or screws. The second connecting flange 4012 and the side panel 103 are fixed together by welding, bolts, or screws.

[0073] In some specific embodiments of this utility model, such as Figure 6 As shown, the second support 402 is connected to the lower end of the first support 401. When the valve island 20 is supported on the second support 402, the overall vertical dimensions of the valve island 20 and valve plate 40 can be reduced, thereby reducing the space occupied by the valve plate 40 and valve island 20 and making it easier to reserve more space for other components in the first chamber 11.

[0074] In some specific embodiments of this utility model, such as Figure 7 As shown, the second support part 402 is connected to one side of the first support part 401 in the horizontal direction to avoid interference between the first support part 401 and the second support part 402, so that the first support part 401 can be stably fixed on the partition 102 and the side panel 103, and the second support part 402 can smoothly support the valve island 20.

[0075] In some specific embodiments of this utility model, the first support part 401 and the second support part 402 are an integral piece, so there is no need to set a connecting part between the first support part 401 and the second support part 402, which makes it easier to reduce the complexity of the valve plate 40 structure and thus reduce the production cost of the valve plate 40.

[0076] In some embodiments, the first support portion 401 and the second support portion 402 are integral sheet metal parts. The valve plate 40 can be formed by bending the sheet metal parts. The portion of the sheet metal parts extending in the vertical direction is the first support portion 401, and the portion of the sheet metal parts extending in the horizontal direction is the second support portion 402.

[0077] In some embodiments of this utility model, such as Figure 6As shown, the valve island 20 includes a fixing part 22, which is connected to the main body part 21. The fixing part 22 protrudes from the main body part 21 and is supported on the valve plate 40. The fixing part 22 is used to support the valve island 20 on the valve plate 40, and the valve plate 40 is used to limit the position of the valve island 20, thereby reducing the possibility of the valve island 20 shaking and making it easier to reduce the shaking frequency and amplitude of the valve island 20.

[0078] In some embodiments, the fixing part 22 protrudes forward from the body part 21 in the front-rear direction and is supported on the valve plate 40 so as to support the position of the valve island 20 by using the valve plate 40, thereby reducing the possibility of the valve island 20 shaking and facilitating the reduction of the shaking frequency and amplitude of the valve island 20.

[0079] In some optional embodiments of this utility model, such as Figure 6 As shown, the fixing part 22 and the body part 21 are integrated to enhance the connection stability between the fixing part 22 and the body part 21. At the same time, there is no need to set a connection structure between the fixing part 22 and the body part 21, which makes it easier to reduce the complexity of the valve island 20 structure and reduce the manufacturing cost of the valve island 20.

[0080] In some embodiments, the body portion 21 includes a flow channel plate and a bottom plate. A fluid channel is formed on one side of the flow channel plate in the thickness direction. The bottom plate cooperates with the flow channel plate to cover the fluid channel. The fluid channel is suitable for the flow of refrigerant.

[0081] The fixing part 22 protrudes forward from the base plate, and the fixing part 22 and the base plate are an integral part.

[0082] In some specific embodiments of this utility model, such as Figure 6 , Figure 7 As shown, the fixing part 22 and the valve plate 40 are fixedly connected to fix the valve island 20 on the valve plate 40, and the position of the valve island 20 is fully fixed by the support part.

[0083] In some embodiments, such as Figure 6 , Figure 7 As shown, the first fastener 71 passes through the fixing part 22 and the valve plate 40 to fix the fixing part 22 and the valve plate 40 together.

[0084] The first fastener 71 can be a screw, bolt, etc., without much restriction.

[0085] In some embodiments of this utility model, such as Figure 4 , Figure 6 As shown, the air conditioner 1 also includes a high-pressure valve 51 and a low-pressure valve 52. The high-pressure valve 51 and the low-pressure valve 52 are respectively connected to the corresponding fluid channels. The valve plate 40 supports the high-pressure valve 51 and the low-pressure valve 52 to limit the position of the high-pressure valve 51 and the low-pressure valve 52.

[0086] Specifically, the high-pressure valve 51 and the low-pressure valve 52 are adapted to be connected to the refrigerant components via the piping system 80. If the positions of the high-pressure valve 51 and the low-pressure valve 52 are not restricted, when the air conditioner 1 vibrates during operation, the high-pressure valve 51 and the low-pressure valve 52 will be driven to shake, affecting the connection stability between the high-pressure valve 51 and the piping system 80, and between the high-pressure valve 51 and the main body 21, as well as the connection stability between the low-pressure valve 52 and the piping system 80, and between the low-pressure valve 52 and the main body 21. Therefore, the high-pressure valve 51 and the low-pressure valve 52 are supported on the valve plate 40 to reduce the frequency and amplitude of the shaking caused by the high-pressure valve 51 and the low-pressure valve 52, thereby improving the connection stability between the high-pressure valve 51 and the piping system 80, and between the high-pressure valve 51 and the main body 21, and also improving the connection stability between the low-pressure valve 52 and the piping system 80, and between the low-pressure valve 52 and the main body 21.

[0087] In some embodiments, the air conditioner 1 includes an indoor unit and an outdoor unit. The housing 10 is the housing of the outdoor unit. The outdoor unit includes a compressor 34 and an outdoor heat exchanger. The indoor unit includes an indoor heat exchanger. The valve island 20 is located in the outdoor unit. The high-pressure valve 51 and the low-pressure valve 52 are used to connect the fluid channels in the indoor heat exchanger and the valve island 20. The valve island 20 is used to connect the indoor heat exchanger and the outdoor unit to realize the circulation of refrigerant between the indoor heat exchanger and the outdoor unit. The indoor heat exchanger is then used to achieve cooling or heating of the room.

[0088] In some optional embodiments of this utility model, such as Figures 5-7 As shown, the valve plate 40 is provided with a receiving recess. The first pipe 61 connecting the high-pressure valve 51 and the main body 21 is supported in the receiving recess, and the second pipe 62 connecting the low-pressure valve 52 and the main body 21 is supported in the receiving recess.

[0089] The first pipe 61 connects one fluid channel between the high-pressure valve 51 and the main body 21, and the second pipe 62 connects the other fluid channel between the low-pressure valve 52 and the main body 21. When the air conditioner 1 vibrates during operation, the first pipe 61 and the second pipe 62 will be driven to shake, affecting the connection stability between the first pipe 61 and the piping system 80, and between the first pipe 61 and the main body 21, as well as the connection stability between the second pipe 62 and the piping system 80, and between the second pipe 62 and the main body 21. Therefore, the first pipe 61 and the second pipe 62 are supported on the valve plate 40 to reduce the frequency and amplitude of the shaking caused by the first pipe 61 and the second pipe 62, thereby improving the connection stability between the first pipe 61 and the piping system 80, the high-pressure valve 51 and the main body 21, and the connection stability between the second pipe 62 and the piping system 80, and between the low-pressure valve 52 and the main body 21.

[0090] In some embodiments, such as Figure 6As shown, the high-pressure valve 51 is connected to the front end of the first pipe 61. The high-pressure valve 51 has a first connecting lug 511 protruding from its outer periphery. A second fastener passes through the first connecting lug 511 and the valve plate 40 to fix the high-pressure valve 51 to the valve plate 40, so that the valve plate 40 can stably support the high-pressure valve 51 and the first pipe 61.

[0091] The low-pressure valve 52 is connected to the front end of the second pipe 62 (it should be understood that the above directional limitation is only for the convenience of describing the drawings and does not limit the actual installation position and direction of the air conditioner 1). The low-pressure valve 52 has a second connecting lug 522 protruding from its outer periphery. The second fastener passes through the second connecting lug 522 and the valve plate 40 to fix the low-pressure valve 52 to the valve plate 40 together, so that the valve plate 40 can stably support the low-pressure valve 52 and the second pipe 62.

[0092] The second fastener can be a screw or bolt, etc., without much restriction.

[0093] In some specific embodiments of this utility model, such as Figures 5-7 As shown, the receiving recess includes a first groove 411 with an open top and a second groove 412 with an open top, so as to facilitate the placement of a first pipe 61 from the open top in the first groove 411 and the placement of a second pipe 62 from the open top in the second groove 412.

[0094] The first tank 411 and the second tank 412 are spaced apart. The first pipe 61 is supported on the first tank 411, and the second pipe 62 is supported on the second tank 412. This independent support of the first pipe 61 and the second pipe 62 in the first and second tanks 412, while using the valve plate 40 to support both pipes, also separates them. This prevents heat exchange between the refrigerant in the first and second pipes due to their close proximity, and also prevents them from vibrating together when the air conditioner 1 vibrates during operation.

[0095] In some embodiments of this utility model, at least a portion of the valve island 20 is made of stainless steel, which gives the valve island 20 better hygiene and safety. Specifically, stainless steel is not prone to bacterial growth and has excellent corrosion resistance, thereby improving the hygiene and safety of the valve island 20 and extending its service life.

[0096] In some embodiments, stainless steel components can be used to define at least a portion of the inner wall of the fluid passage within the body portion 21. This makes the inner wall of the fluid passage smooth, resulting in less resistance to the liquid. Simultaneously, it also makes the inner wall of the fluid passage rigid, providing good resistance to liquid erosion and facilitating an increase in the service life of the valve island 20.

[0097] In some embodiments of this utility model, the body part 21 includes a flow channel plate and a bottom plate. A plurality of fluid channels are formed on one side of the flow channel plate in the thickness direction. The bottom plate cooperates with the flow channel plate to cover the plurality of fluid channels. This facilitates the formation of a plurality of fluid channels on the body part 21 and reduces the difficulty of molding.

[0098] Specifically, the fluid channel is a channel with a certain length. If a relatively closed fluid channel is formed directly on the body 21, the molding difficulty is relatively high. Therefore, in this embodiment, the fluid channel is formed on the flow channel plate and the fluid channel is covered by the bottom plate, which makes the manufacturing of the fluid channel simpler, facilitates the reduction of production costs and improves production efficiency.

[0099] In some optional embodiments of this utility model, such as Figure 6 As shown, the base plate has an interface portion that communicates with the fluid channel, and the body portion 21 also includes a plate heat exchanger 23. The plate heat exchanger 23 is disposed on the base plate and has multiple plate heat exchanger 23 interfaces, at least one of which is connected to the interface portion.

[0100] Plate heat exchanger 23 is suitable for exchanging heat with the refrigerant in valve island 20. Of course, plate heat exchanger 23 can also exchange heat with other structures outside valve island 20.

[0101] In some embodiments, the air conditioner 1 includes a gas-liquid separator 31, a compressor 34, and an oil separator 32. The piping system 80 includes multiple pipes connected to the valve island 20 and communicating with the compressor 34 and the gas-liquid separator 31, thereby forming a refrigerant circuit using fluid channels.

[0102] The flow path of refrigerant in air conditioner 1 can be simply summarized as follows: after the refrigerant flows out of compressor 34, it can flow into oil separator 32. After passing through oil separator 32, it flows to four-way valve 91. Under the control of four-way valve 91, the refrigerant enters body section 21 through four-way valve 91, and flows to indoor heat exchanger through one of the shut-off valves. Then it enters indoor heat exchanger for heat exchange. After heat exchange, the refrigerant flows back to body section 21 through another shut-off valve, and flows to plate heat exchanger 23 through interface section and enters plate heat exchanger 23. At this time, the refrigerant is diverted: one part of the refrigerant enters the main body section 21 after being further throttled by the electronic expansion valve 92. The refrigerant undergoes full heat exchange with the main circuit in the plate heat exchanger 23 and flows back to the compressor 34 under the guidance of the fluid channel in the main body section 21; the other part of the refrigerant flows out through the refrigerant heat dissipation pipe and flows through the main electronic expansion valve 92. Finally, it passes through the filter and enters the outdoor heat exchanger. After the outdoor heat exchanger exchanges heat with the outdoor environment, the refrigerant enters the four-way valve 91 and undergoes gas-liquid separation through the gas-liquid separator 31, and finally flows back to the compressor 34.
