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

[0043] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0044] like Figures 1-10 As shown, the air conditioner 100 according to an embodiment of the present utility model includes: a housing 1, a valve island 21, a support member 8, and a fixing bracket 3; the valve island 21 is provided with multiple fluid channels and is disposed inside the housing 1; the support member 8 is installed on the housing 1, and the valve island 21 is fixed to the support member 8; the fixing bracket 3 is used to fix the support member 8 to the housing 1.

[0045] First, such as Figures 1-7 As shown, the air conditioner 100 includes an outer casing 1 and a piping system 2. The outer casing 1 includes a base plate 12 and a housing 11. The base plate 12 is located at the bottom of the housing 11. The piping system 2 is located inside the outer casing 1. The piping system 2 includes at least a four-way valve 25, an electronic expansion valve 26, a plate heat exchanger 27, an oil separator 28, a single-way solenoid valve 29, a high-pressure valve 23, and a low-pressure valve 24.

[0046] The valve island 21 is equipped with multiple fluid channels for the flow of refrigerant. The four-way valve 25, electronic expansion valve 26, plate heat exchanger 27, oil separator 28, single-way solenoid valve 29, high-pressure valve 23 and low-pressure valve 24 are respectively connected to the corresponding fluid channels so that the valve island 21 can connect multiple components together to form a refrigerant circuit.

[0047] The above setup reduces pipe length, lowers costs and space requirements, reduces pipe resistance and pressure loss, and enables integrated layout of pipe system 2. Pipe system 2 can be pre-installed and leak-tested, saving welding time and weld points in the assembly of air conditioner 100 and reducing the probability of weld point leakage.

[0048] The air conditioner 100 also includes a support member 8 and a fixing bracket 3. The support member 8 is installed on the outer casing 1, the valve island 21 is fixed to the support member 8, and the fixing bracket 3 is used to fix the support member 8 to the outer casing 1. It should be noted that the fixing bracket 3 and the outer casing 1 can be directly connected or indirectly connected.

[0049] Specifically, the fixed bracket 3 can be connected to the outer shell 1; or, the fixed bracket 3 can be connected to the components fixed to the outer shell 1, such as the plate heat exchanger 27, the oil separator 28, the refrigerant flow path, the flow path plate, the electrical control box, the heat exchanger 7, etc.; or, the fixed bracket 3 can be connected to the outer shell 1 and the components fixed to the outer shell 1 respectively. This utility model does not limit this.

[0050] With the above configuration, the fixed bracket 3 and the outer shell 1 can jointly fix the support member 8, so that the support member 8 can better support the valve island 21 and improve the installation stability of the valve island 21.

[0051] According to the embodiment of the present utility model, the air conditioner 100, by setting the valve island 21, can reduce the length of the pipeline, reduce costs, reduce space occupation, and enable the pre-installation and leak detection of the pipeline system 2, which helps to reduce the probability of weld point leakage. Furthermore, by setting the fixed bracket 3, the outer shell 1 and the fixed bracket 3 can jointly fix the support member 8, so that the support member 8 can better support the valve island 21, improve the installation stability of the valve island 21, and thus improve the overall reliability of the air conditioner 100.

[0052] It should be noted that the air conditioner 100 can be either an integrated unit or a split unit. When the air conditioner 100 is a split unit, the piping system 2 can be located inside the outer casing of the outdoor unit or the inner casing of the indoor unit. Of course, the present invention is not limited to this; the outer casing 1 can also be constructed as an independent structure, with only the piping system 2 installed inside the outer casing 1, so that the arrangement of the air conditioner 100 is more flexible.

[0053] In some embodiments of the present invention, such as Figure 3 As shown, the support member 8 includes a gas-liquid separator 22, which is fixed to the base plate 12 of the outer casing 1. A valve island 21 is fixed to the gas-liquid separator 22. The gas-liquid separator 22 is part of the pipeline system 2 and communicates with corresponding fluid channels. A fixing bracket 3 is connected to the gas-liquid separator 22. It should be noted that the support member 8 can also be other components fixed to the base plate 12, or components fixed to the outer peripheral plate 112 described below, or components fixed to the partition plate 111 described below; this utility model does not limit this.

[0054] Understandably, by setting the gas-liquid separator 22 as the support member 8, more installation space can be reserved for the valve island 21, reducing the difficulty of connecting the valve island 21 and the support member 8.

[0055] Preferably, the fixing bracket 3 can be connected to the upper part of the gas-liquid separator 22 so that the fixing bracket 3 and the base plate 12 can fix the gas-liquid separator 22 from the upper and lower ends respectively, which helps to improve the stability of the gas-liquid separator 22.

[0056] It should be noted that the valve island 21 can be directly attached to the outer wall of the gas-liquid separator 22, which can improve space utilization and allow the valve island 21 and the gas-liquid separator 22 to be directly connected, eliminating the need for connecting pipes between the valve island 21 and the gas-liquid separator 22, which simplifies the structure and reduces costs; or, the valve island 21 and the outer wall of the gas-liquid separator 22 can be arranged separately, which helps to reduce the installation difficulty of the valve island 21 and avoids mutual compression between the valve island 21 and the gas-liquid separator 22, thus improving the installation stability of the valve island 21.

[0057] In some embodiments of this utility model, such as Figure 6 As shown, the fixed bracket 3 can be placed at the top of the gas-liquid separator 22. This makes it easier to position and connect the fixed bracket 3 with the gas-liquid separator 22, improves the installation accuracy of the fixed bracket 3, enhances the support effect of the fixed bracket 3 on the gas-liquid separator 22, improves the stability of the valve island 21, and allows for more space to be reserved for the fixed bracket 3, thus improving the design rationality of the air conditioner 100.

[0058] In some embodiments of this utility model, such as Figure 6 As shown, an external pipe 221 can be connected to the top of the gas-liquid separator 22. The connecting pipe is used to communicate with related components, and the fixed bracket 3 is connected to the external pipe 221. This can improve the connection stability between the fixed bracket 3 and the gas-liquid separator 22, which is beneficial to improving the stability of the valve island 21.

[0059] In some embodiments of this utility model, such as Figure 6 As shown, the external connector 221 includes a first external connector 222 and a second external connector 223, which are spaced apart. The first external connector 222 is connected to a corresponding fluid channel, and the second external connector 223 is connected to a related component. The fixed bracket 3 is connected to the second external connector 223. Therefore, when the fixed bracket 3 vibrates, the interference of the fixed bracket 3 on the valve island 21 can be reduced, thus improving the stability of the valve island 21.

[0060] In some embodiments of this utility model, the fixing bracket 3 includes a main body 31 and a limiting part 32. The limiting part 32 is connected to the main body 31 and protrudes from the side of the main body 31 facing the gas-liquid separator 22. The main body 31 is provided with a limiting groove 311. The fixing bracket 3 has an installation position. In the installation position, the limiting part 32 is limited and engaged with the outer peripheral wall of the gas-liquid separator 22 along the first direction F1. The outer pipe 221 is snapped into the limiting groove 311 and the main body 31 is limited and engaged with the outer pipe 221 along the second direction F2. The first direction F1 and the second direction F2 are opposite directions.

[0061] For example, refer to Figures 6-7As shown, the fixed bracket 3 includes a main body 31 and a limiting part 32. The main body 31 is plate-shaped and is attached to the top of the gas-liquid separator 22. The limiting part 32 is connected to the main body 31 and protrudes from the side of the main body 31 facing the gas-liquid separator 22. The main body 31 is provided with a limiting groove 311, which is matched with the outer pipe 221.

[0062] The fixed bracket 3 has an installation position. In the installation position, the limiting part 32 is limited and engaged with the outer peripheral wall of the gas-liquid separator 22 along the first direction F1, and the outer pipe 221 is snapped into the limiting groove 311. The main body 31 can be limited and engaged with the outer pipe 221 located in the limiting groove 311 along the second direction F2. The first direction F1 and the second direction F2 are opposite directions, so that the fixed bracket 3 can be snapped between the gas-liquid separator 22 and the outer pipe 221.

[0063] The above settings can reduce the difficulty of disassembling and assembling the fixed bracket 3, facilitate subsequent maintenance, improve the practicality of the air conditioner 100, and improve the installation stability of the fixed bracket 3, thereby enhancing the support effect of the fixed bracket 3 on the gas-liquid separator 22.

[0064] In some embodiments of this utility model, such as Figure 7 As shown, the fixing bracket 3 also includes a connecting portion 33, which is connected to one side of the main body 31 along the first direction F1 or the second direction F2. The connecting portion 33 is used to connect to the outer casing 1. For example, the connecting portion 33 can be connected to one side of the main body 31 along the first direction F1; or, the connecting portion 33 can be connected to one side of the main body 31 along the second direction F2.

[0065] By setting the above, the limiting direction of the fixed bracket 3 can be kept consistent with the vibration transmission direction, which can prevent the fixed bracket 3 from loosening due to vibration and improve the installation stability of the fixed bracket 3.

[0066] In some embodiments of this utility model, such as Figures 6-7 As shown, the connecting part 33 can be provided to protrude from the side of the main body 31 away from the gas-liquid separator 22, so that the connecting part 33 and the limiting part 32 are respectively located on both sides of the main body 31 in the vertical direction. This makes the structure of the fixed bracket 3 more uniform, improves the structural strength of the fixed bracket 3, enhances the installation stability of the fixed bracket 3, and improves the design rationality of the fixed bracket 3.

[0067] In some embodiments of this utility model, such as Figure 7 As shown, the limiting groove 311 can be provided, including an inlet section 3111 and a snap-fit ​​section 3113 that are bent and connected. In the installation position, the outer pipe 221 extends through the inlet section 3111 into the snap-fit ​​section 3113 to engage with the inner wall of the snap-fit ​​section 3113 for limiting.

[0068] The above settings prevent vibration from causing the outer pipe 221 to disengage from the limiting groove 311, improve the installation stability of the fixed bracket 3, thereby ensuring the support effect of the fixed bracket 3 on the gas-liquid separator 22 and improving the reliability of the air conditioner 100.

[0069] In some embodiments of this utility model, such as Figure 7 As shown, the limiting groove 311 also includes a transition section 3112, which is arc-shaped and is used to connect the inlet section 3111 and the snap-fit ​​section 3113. This makes it easier for the outer pipe 221 to snap into the snap-fit ​​section 3113, reducing the installation difficulty of the fixed bracket 3 and improving the design rationality of the fixed bracket 3.

[0070] In some embodiments of this utility model, such as Figure 8 As shown, the fixing bracket 3 can be connected to the outer peripheral wall of the gas-liquid separator 22, and the end of the fixing bracket 3 facing away from the gas-liquid separator 22 is used to connect to the housing 1 and / or the components fixed to the housing 1.

[0071] For example, the fixing bracket 3 can be welded to the outer peripheral wall of the gas-liquid separator 22; or, a snap-fit ​​structure can be provided on the outer peripheral wall of the gas-liquid separator 22, and the fixing bracket 3 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 22, and a connecting through hole can be provided on the fixing bracket 3, with the screw connecting member passing through the connecting through hole and being screwed to the threaded hole; or, the fixing bracket 3 can be fixed to the outer peripheral wall of the gas-liquid separator 22 by rivets, and the present invention does not limit this.

[0072] The above settings can maintain a sufficient distance between the fixed bracket 3 and the valve island 21, which helps to prevent the fixed bracket 3 from contacting the valve island 21 during vibration and improves the installation stability of the valve island 21.

[0073] In some embodiments of this utility model, such as Figure 7 As shown, the mounting bracket 3 is provided with a connecting screw hole 331, through which a screw thread passes to be detachably connected to the housing 1 and / or components fixed to the housing 1. This reduces the difficulty of assembling and disassembling the mounting bracket 3, making the air conditioner 100 easier to maintain and improving its practicality.

[0074] In some embodiments of the present invention, the air conditioner 100 of the present invention further includes a mounting bracket 43, which is mounted on the gas-liquid separator 22 and used to support the valve island 21.

[0075] For example, refer to Figures 3-4As shown, the air conditioner 100 also includes a mounting bracket 43, which includes a mounting part 41 and a support part 42 connected to the mounting part 41. The mounting part 41 is connected to the gas-liquid separator 22 and is used to support the valve island 21. The plate heat exchanger 27 is fixed below the valve island 21, and the support part 42 is located at the bottom of the plate heat exchanger 27 and is used to support the plate heat exchanger 27. Through the above arrangement, the mating area between the gas-liquid separator 22 and the valve island 21 can be increased, which is beneficial to improving the connection stability between the gas-liquid separator 22 and the valve island 21, and improving the installation stability of the valve island 21.

[0076] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 As shown, the outer casing 1 includes a housing 11, which includes an outer peripheral plate 112 and a partition 111. The outer peripheral plate 112 defines a cavity, and the partition 111 is disposed within the cavity. The partition 111 is used for horizontal movement (see reference). Figure 1 The cavity is divided into a fan chamber 114 and a compressor chamber 113 (shown in the left-right direction). An outdoor fan 6 is housed in the fan chamber 114, and a compressor 5 and piping system 2 are housed in the compressor chamber 113. A fixed bracket 3 is located within the compressor chamber 113. This design separates the fixed bracket 3 from the outdoor fan 6, preventing impact from the outdoor fan 6 and improving the installation stability of the fixed bracket 3.

[0077] In some embodiments of this utility model, such as Figure 8 As shown, the fixed bracket 3 is fixedly engaged with the partition 111 and / or the outer plate 112. Specifically, the fixed bracket 3 can be fixedly engaged with the partition 111; or, the fixed bracket 3 can be fixedly engaged with the outer plate 112; or, the fixed bracket 3 can be connected to both the partition 111 and the outer plate 112 respectively. This invention does not limit the specific arrangements. Therefore, the fixed bracket 3 can be flexibly arranged, which helps to reduce the layout difficulty of the air conditioner 100.

[0078] In some embodiments of this utility model, such as Figure 1 As shown, the outer panel 112 includes a front panel, a rear panel, a left side panel, and a right side panel. The front panel, rear panel, right side panel, and partition 111 together enclose the compressor cavity 113. The fixed bracket 3 can be fixedly engaged with any one of the front panel, rear panel, right side panel, and partition 111. This facilitates meeting different design requirements.

[0079] In some embodiments of this utility model, such as Figure 1 , Figure 9 and Figure 10As shown, a heat exchanger 7 is installed inside the fan cavity 114. The heat exchanger 7 is positioned opposite the air outlet side of the outdoor fan 6 so that the airflow blown out by the outdoor fan 6 can exchange heat with the heat exchanger 7. The heat exchanger 7 is fixedly connected to the outer casing 1. The heat exchanger 7 is equipped with a flow channel integrated plate 71, which extends into the compressor cavity 113 and is connected to the compressor 5 through the valve island 21, allowing refrigerant to flow into or out of the heat exchanger 7 through the flow channel integrated plate 71. A fixing bracket 3 can be connected to the flow channel integrated plate 71 so that the heat exchanger 7 can support the gas-liquid separator 22.

[0080] With the above configuration, the fixed bracket 3 can transmit vibration to the outside of the compressor cavity 113, which helps to reduce the impact of vibration on the valve island 21 and improves the stability of the air conditioner 100.

[0081] In some embodiments of this invention, at least a portion of the fluid channels within the valve island 21 are made of stainless steel. This means that multiple fluid channels are provided within the valve island 21, and these channels are either interconnected or separated. For example, one, two, or more of the multiple fluid channels may be made of stainless steel to give the fluid channels higher structural strength, greater high-temperature resistance, and improved corrosion resistance.

[0082] This makes the internal structure of the piping system 2 more stable, less prone to corrosion or structural damage, improves the safety of the piping system 2, and ensures the reliability of refrigerant flow in the refrigerant circuit.
