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

[0045] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0046] like Figures 1-7 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, a first heat exchanger 7, and a fixed bracket 3. The valve island 21 is provided with multiple fluid channels and is located inside the housing 1. The support member 8 is fixed to the housing 1, and the valve island 21 is fixed to the support member 8. The fixed bracket 3 is used to fix the valve island 21 to the housing 1.

[0047] First, such as Figures 1-4 As shown, the air conditioner 100 includes a housing 1 and a piping system 2. The piping system 2 is located inside the housing 1 and includes at least a high-pressure valve 23, a low-pressure valve 24, a four-way valve 25, an electronic expansion valve 26, an oil separator 28, and a valve island 21. The valve island 21 has multiple fluid channels for circulating refrigerant. The high-pressure valve 23, low-pressure valve 24, four-way valve 25, electronic expansion valve 26, and oil separator 28 are respectively connected to their respective fluid channels. The valve island 21 connects multiple components together to form a refrigerant circuit.

[0048] 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.

[0049] The air conditioner 100 also includes a support member 8 and a fixing bracket 3. The support member 8 is fixed to 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 valve island 21 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.

[0050] For example, 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 first 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.

[0051] The above configuration allows the support member 8 and the fixed bracket 3 to jointly fix the valve island 21, thereby improving the installation stability of the valve island 21.

[0052] 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 the cost, reduce the space occupation, and realize 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 support member 8 and the fixed bracket 3 can jointly fix the valve island 21, realizing the stable installation of the valve island 21 and improving the overall stability of the air conditioner 100.

[0053] 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, this utility model 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.

[0054] In some embodiments of this utility model, a fixed bracket 3 can be detachably connected to the valve island 21. Specifically, as shown in the figure... Figure 4 As shown, a connecting screw hole 331 can be provided on the fixed bracket 3, and a screw connector passes through the connecting screw hole 331 to be detachably connected to the valve island 21, so that the fixed bracket 3 can be detachably installed on the valve island 21. This facilitates subsequent maintenance and improves the practicality of the air conditioner 100.

[0055] In some embodiments of this utility model, such as Figure 4As shown, the fixing bracket 3 can be supported at the bottom of the valve island 21. This allows the fixing bracket 3 to better support the valve island 21, which helps to improve the installation stability of the valve island 21 and improves the reliability of the air conditioner 100.

[0056] In some embodiments of this utility model, such as Figures 4-5 As shown, the fixed bracket 3 includes a main body 31, a connecting part 32, and a support part 33. One end of the main body 31 is fixed to the outer shell 1, and the other end is connected to the connecting part 32. The support part 33 is connected to the upper side of the connecting part 32. The support part 33 extends horizontally and is used to support the bottom of the valve island 21. Exemplarily, the main body 31 and the first heat exchanger 7 can be fixedly connected by screws; or, the main body 31 and the first heat exchanger 7 can be fixedly connected by rivets.

[0057] The above settings can increase the connection area between valve island 21 and fixed bracket 3, improve the connection stability between valve island 21 and fixed bracket 3, and help improve the installation stability of valve island 21.

[0058] In some embodiments of this utility model, such as Figure 5 As shown, multiple support portions 33 can be provided, spaced apart along the extension direction of the connecting portion 32. These multiple support portions 33 are respectively positioned at different locations on the bottom of the valve island 21 to collectively support the valve island 21. This prevents the valve island 21 from becoming unbalanced due to localized impacts, thus improving the installation stability of the valve island 21.

[0059] In some embodiments of this utility model, such as Figure 5 As shown, the connecting portion 32 includes a first portion 321 and a second portion 322. The first portion 321 and the second portion 322 are arranged sequentially along the extending direction of the connecting portion 32. The first portion 321 is connected to the support portion 33, and at least a portion of the second portion 322 is offset from the first portion 321 in the direction intersecting with the extending direction of the connecting portion 32.

[0060] For example, the connecting portion 32 can be arranged to extend in the front-back direction, the first portion 321 and the second portion 322 can be arranged sequentially in the front-back direction, and at least a portion of the first portion 321 can be offset from the second portion 322 in the left-right direction; or, the connecting portion 32 can be arranged to extend in the front-back direction, the first portion 321 and the second portion 322 can be arranged sequentially in the front-back direction, and at least a portion of the first portion 321 can be offset from the second portion 322 in the up-down direction.

[0061] The above-mentioned configuration can improve the structural stability of the connecting part 32, enhance the supporting effect of the connecting part 32 on the supporting part 33, thereby strengthening the connection stability between the valve island 21 and the fixed bracket 3, and improving the installation stability of the valve island 21.

[0062] In some embodiments of this utility model, such as Figures 4-5 As shown, in the direction near the main body 31, at least a portion of the connecting portion 32 gradually decreases in size along the vertical direction to form a clearance notch in the connecting portion 32, which is used for the other components of the air conditioner 100. This reduces the size of the connecting portion 32, improving space utilization and making the air conditioner 100 easier to arrange, thus enhancing the design rationality of the air conditioner 100.

[0063] In some embodiments of this utility model, such as Figures 4-5 As shown, a reinforcing flange 311 can be provided on at least one side of the main body 31 along the vertical direction. The reinforcing flange 311 can be configured to extend towards or away from the gas-liquid separator 22. Exemplarily, a reinforcing flange 311 can be provided on the upper side of the main body 31; or, a reinforcing flange 311 can be provided on the lower side of the main body 31; or, reinforcing flanges 311 can be provided on both the upper and lower sides of the main body 31 respectively. This invention does not limit the scope of the invention. Therefore, the structural strength of the fixing bracket 3 can be enhanced, allowing the fixing bracket 3 to better support the valve island 21 and improving the installation stability of the valve island 21.

[0064] In some embodiments of this utility model, such as Figure 3 As shown, the air conditioner 100 of this utility model embodiment also includes: a gas-liquid separator 22, which is formed as a support member, a valve island 21 is fixed to the top of the gas-liquid separator 22, the gas-liquid separator 22 is part of the pipeline system 2, and the gas-liquid separator 22 is connected to the corresponding fluid channel.

[0065] 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.

[0066] Of course, this utility model is not limited to this, and other components can also be set to form the support member 8, such as plate heat exchanger 27, oil separator 28, etc.

[0067] It should be noted that the valve island 21 can be directly attached to the outer wall of the gas-liquid separator 22 to improve space utilization and eliminate the need for connecting pipes between the valve island 21 and the gas-liquid separator 22, which simplifies the structure and reduces costs. Alternatively, the valve island 21 can be arranged separately from the outer wall of the gas-liquid separator 22, which reduces 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.

[0068] In some embodiments of this utility model, such as Figures 3-4 As shown, the air conditioner 100 of this embodiment further includes a mounting bracket 4, which is installed on the top of the gas-liquid separator 22 and supports the valve island 21. This increases the mating area between the gas-liquid separator 22 and the valve island 21, thus improving the installation stability of the valve island 21.

[0069] In some embodiments of this utility model, such as Figure 4 As shown, the mounting bracket 4 and the fixing bracket 3 can be provided to support different sides of the valve island 21. For example, the mounting bracket 4 can be supported on one side of the valve island 21 along its length, and the fixing bracket 3 can be supported on one side of the valve island 21 along its width; alternatively, the mounting bracket 4 and the fixing bracket 3 can be supported on both sides of the valve island 21 along its width. This improves the installation stability of the valve island 21 and enhances the overall reliability of the air conditioner 100.

[0070] In some embodiments of this utility model, such as Figure 4 As shown, the air conditioner 100 of this utility model embodiment also includes a plate heat exchanger 27. The plate heat exchanger 27 is part of the piping system 2. The plate heat exchanger 27 is connected to the valve island 21 and communicates with the corresponding fluid channel. The plate heat exchanger 27 is supported above the mounting bracket 4.

[0071] It is understandable that by setting the mounting bracket 4, the plate heat exchanger 27 can be supported, which can eliminate the pressure exerted by the plate heat exchanger 27 on the valve island 21, thereby reducing the overall stress on the valve island 21 and improving the structural stability of the valve island 21.

[0072] In some embodiments of this utility model, the mounting bracket 4 includes a first sub-plate 41, a connecting plate 42, and a second sub-plate 43. The connecting plate 42 extends vertically, and the first sub-plate 41 and the second sub-plate 43 both extend horizontally and are connected to the upper and lower ends of the connecting plate 42. The first sub-plate 41 and the second sub-plate 43 are located on different sides of the connecting plate 42. The first sub-plate 41 is supported on the top surface of the gas-liquid separator 22, and the plate heat exchanger 27 is supported above the second sub-plate 43.

[0073] For example, refer to Figure 4 and Figure 6 As shown, the mounting bracket 4 includes a first sub-plate 41, a connecting plate 42, and a second sub-plate 43. The connecting plate 42 extends vertically, the first sub-plate 41 is connected to the upper end of the connecting plate 42, and the second sub-plate 43 is connected to the lower end of the connecting plate 42. Both the first sub-plate 41 and the second sub-plate 43 extend horizontally and are located on different sides of the connecting plate 42 along the horizontal direction, thus constructing the mounting bracket 4 in a Z-shape. The first sub-plate 41 is used to support the top surface of the gas-liquid separator 22 and is connected to the gas-liquid separator 22 to fix the fixing bracket 3 on the gas-liquid separator 22. The first sub-plate 41 is also used to support the bottom of the valve island 21, and the second sub-plate 43 extends to the bottom of the plate heat exchanger 27 so that the plate heat exchanger 27 can be supported above the second sub-plate 43.

[0074] With the above configuration, the mounting bracket 4 can not only directly support the valve island 21, but also indirectly support the valve island 21 through the plate heat exchanger 27, thereby improving the support effect of the mounting bracket 4 on the valve island 21 and improving the installation stability of the valve island 21.

[0075] In some embodiments of this utility model, such as Figure 6 As shown, the second sub-plate 43 can be provided with a first limiting flange 44 on the side edge away from the connecting plate 42. The first limiting flange 44 is bent upward and distributed opposite to the connecting plate 42. The first limiting flange 44 is used to limit the engagement with the plate heat exchanger 27.

[0076] The above settings enhance the limiting effect of the mounting bracket 4 on the plate heat exchanger 27, which helps to reduce the amplitude of the plate heat exchanger 27 under impact force, reduces the negative impact of the plate heat exchanger 27 on the valve island 21, and improves the installation stability of the valve island 21.

[0077] 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.

[0078] 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.

[0079] In some embodiments of this utility model, the support member 8 can be constructed as a valve plate, which is fixed to the outer casing 1, and the valve island 21 is fixed to the valve plate. Thus, the valve island 21 can be supported independently by the valve plate, allowing the arrangement of the valve island 21 to be unrestricted by other components, making the arrangement of the valve island 21 more flexible and reducing the layout difficulty of the air conditioner 100.

[0080] In some embodiments of this utility model, such as Figure 1 and Figure 7 As shown, the outer casing 1 includes an outer perimeter plate 12 and a partition plate 11. The outer perimeter plate 12 defines a cavity, and the partition plate 11 is disposed within the cavity. The partition plate 11 is used for horizontal movement (see reference). Figure 1 The cavity is divided into a fan chamber 14 and a compressor chamber 13 (shown in the left-right direction). The fan chamber 14 houses an outdoor fan 6, and the compressor chamber 13 houses a compressor 5 and a piping system 2. A fixed bracket 3 is located inside the compressor chamber 13. This separates the fixed bracket 3 from the outdoor fan 6, reducing the impact of the outdoor fan 6 on the fixed bracket 3 and improving the installation stability of the fixed bracket 3.

[0081] In some embodiments of this utility model, such as Figure 7 As shown, the fixed bracket 3 can be fixedly engaged with the partition 11 and / or the outer plate 12. Specifically, the fixed bracket 3 can be fixedly engaged with the partition 11; or, the fixed bracket 3 can be fixedly engaged with the outer plate 12; or, the fixed bracket 3 can be connected to both the partition 11 and the outer plate 12 respectively. This utility model does not limit the scope of the invention. Therefore, the arrangement of the fixed bracket 3 can be more flexible, improving the design rationality of the air conditioner 100.

[0082] In some embodiments of this utility model, such as Figure 1 As shown, the outer panel 12 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 11 together enclose the compressor cavity 13. The fixed bracket 3 can be fixedly engaged with any one of the front panel, rear panel, right side panel, and partition 11. This facilitates meeting different design requirements.

[0083] In some embodiments of this utility model, such as Figures 1-2 As shown, a first heat exchanger 7 is provided in the fan cavity 14. The first heat exchanger 7 is arranged opposite to 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 first heat exchanger 7. The first heat exchanger 7 is fixedly connected to the outer shell 1, and a part of the first heat exchanger 7 extends into the compressor cavity 13 to be fixedly engaged with the fixed bracket 3.

[0084] With the above configuration, the fixed bracket 3 can transmit vibration to the outside of the compressor cavity 13, which helps to reduce the impact of vibration on the components inside the compressor cavity 13 and improves the stability of the air conditioner 100.

[0085] In some embodiments of this utility model, such as Figures 2-3 As shown, the first heat exchanger 7 is provided with a flow channel integrated plate 71, which extends into the compressor cavity 13 and is connected to the compressor 5 through the valve island 21. Refrigerant can flow into or out of the first heat exchanger 7 through the flow channel integrated plate 71. The fixed bracket 3 is connected to the flow channel integrated plate 71 so that the first heat exchanger 7 can support the valve island 21.

[0086] The above settings can simplify the structure of the first heat exchanger 7, reduce the processing difficulty of the first heat exchanger 7, and help improve the design rationality of the air conditioner 100.
