The refrigerant shut-off control component includes a refrigerant shut-off valve box with a shut-off valve and connecting pipeline, and an electrical control box with an electrical control board connected to the shut-off valve wire. When refrigerant leakage occurs, the electrical control board controls the shut-off valve to cut off the refrigerant path flowing through the refrigerant pipeline according to the control signal, so as to cut off the refrigerant on the outdoor side, thereby reducing the amount of refrigerant leakage indoors.

[0062] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 1 The orientation or positional relationship shown, "third direction" is based on the attached Figure 3The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0063] This application provides an air conditioner, which includes an indoor unit, an outdoor unit, a refrigerant cut-off control component, and refrigerant piping.

[0064] Please see Figure 1 The refrigerant shut-off control component includes a refrigerant shut-off valve box 10 and an electrical control box 20. The refrigerant shut-off valve box 10 and the electrical control box 20 are connected by wires, that is, the refrigerant shut-off valve box 10 and the electrical control box 20 are electrically connected through connecting wires.

[0065] The refrigerant shut-off control component can be installed indoors or outdoors. The indoor unit, outdoor unit, and refrigerant shut-off valve box 10 are connected through refrigerant pipelines. In other words, the refrigerant circulates along the refrigerant pipelines and can flow through the indoor unit, outdoor unit, and refrigerant shut-off valve box 10.

[0066] Specifically, please refer to Figure 1 , Figure 3 and Figure 5 The refrigerant shut-off valve box 10 includes a valve box body 11, a connecting pipe 12, and a shut-off valve 13. The valve box body 11 has a first receiving cavity 111a, and the connecting pipe 12 is at least partially located within the first receiving cavity 111a. That is, the entire connecting pipe 12 can be located within the first receiving cavity 111a, or it can be as follows: Figure 1 A portion of the connecting pipe 12 shown is located inside the first receiving cavity 111a, and the other portion of the connecting pipe 12 extends out of the valve box body 11.

[0067] The connecting pipe 12 is used to connect to the refrigerant pipe. That is, the indoor unit, the outdoor unit and the connecting pipe 12 are connected through the refrigerant pipe. The refrigerant circulating along the refrigerant pipe flows through the connecting pipe 12 of the refrigerant shut-off valve box 10.

[0068] It is understandable that for the refrigerant shut-off valve box 10, where the entire connecting pipeline 12 is located within the first receiving cavity 111a, the valve box body 11 will also be provided with a connection port that communicates with the outside world, and the connecting pipeline 12 and the refrigerant pipeline are connected through the connection port.

[0069] Please see Figure 8 The shut-off valve 13 is disposed in the connecting pipe 12 and located in the first receiving cavity 111a, for opening or closing the connecting pipe 12. That is, the shut-off valve 13 can cut off the passage in the connecting pipe 12 to prevent the refrigerant from flowing, or it can open the passage in the connecting pipe 12 to allow the refrigerant to flow normally.

[0070] For example, please refer to Figure 5 , Figure 12 and Figure 13 The refrigerant shut-off valve box 10 can be equipped with two separate connecting pipes 12, which are spaced apart, and each connecting pipe 12 is equipped with a shut-off valve 13.

[0071] Please see Figure 3 , Figure 6 , Figure 17 and Figure 18 The valve box body 11 includes a valve box body 111 and a valve box cover 112. The valve box body 111 has a first receiving cavity 111a and a first mounting port 111b communicating with the first receiving cavity 111a. The valve box cover 112 is closable and covers the first mounting port 111b. After the valve box cover 112 is opened, the connecting pipe 12 and the shut-off valve 13 can be disassembled and assembled through the first mounting port 111b. After the valve box cover 112 is closed, the valve box cover 112 blocks the first mounting port 111b, so that the first receiving cavity 111a forms a relatively closed space. The electrical control box 20 can be disposed outside or inside the valve box body 11.

[0072] Please see Figure 3 , Figure 5 and Figure 6 The control box 20 includes a control box body 21 having a second receiving cavity 211a and a control board 22 disposed in the second receiving cavity 211a. The control board 22 is connected to the wire of the shut-off valve 13.

[0073] For the electrical control box 20 located outside the valve box body 11, the electrical control box body 21 of the electrical control box 20 generally includes an electrical control box body 211 and an electrical control box cover 212. The electrical control box body 211 has a second receiving cavity 211a and a second mounting port 211c communicating with the second receiving cavity 211a. The electrical control box cover 212 is closable and covers the second mounting port 211c. After the electrical control box cover 212 is opened, the electrical control board 22 can be installed and removed through the second mounting port 211c. After the electrical control box cover 212 is closed, the electrical control box cover 212 blocks the second mounting port 211c, so that the second receiving cavity 211a forms a relatively closed space.

[0074] For the electrical control box 20 installed inside the valve box body 11, the electrical control box body 21 of the electrical control box 20 may have an electrical control box body 211 and an electrical control box cover 212, or it may only have an electrical control box body 211. For example, the valve box cover 112 may simultaneously cover the first mounting port 111b and the second mounting port 211c of the electrical control box body 211.

[0075] Additionally, for the electrical control box 20 located outside the valve box body 11, the electrical control box body 21 of the electrical control box 20 is generally connected to the valve box body 11 of the refrigerant shut-off valve box 10. To facilitate the disassembly and assembly of the electrical control box 20, the electrical control box body 21 of the electrical control box 20 can be detachably connected to the valve box body 11 of the refrigerant shut-off valve box 10; for example, the electrical control box body 21 and the valve box body 11 can be fastened together using screws or other fasteners. The refrigerant shut-off control component is generally installed close to the indoor side. During normal operation of the air conditioner, the connecting pipe 12 is in a conductive state, allowing the refrigerant to circulate along the refrigerant pipe.

[0076] When refrigerant leaks in the refrigerant pipeline, the electronic control board 22 cuts off the connecting pipeline 12 by controlling the shut-off valve 13 according to the control signal, which can stop the refrigerant flow. Thus, the refrigerant can be cut off on the outdoor side, thereby reducing the amount of refrigerant leakage indoors.

[0077] In related technologies, refrigerant shut-off control components are generally installed with lifting lugs on the valve box body. The refrigerant shut-off control components are installed by hoisting using the lifting lugs. However, in some installation scenarios, the refrigerant shut-off control components may not be suitable for hoisting installation. Therefore, the refrigerant shut-off control components in related technologies are difficult to meet the installation requirements of different scenarios.

[0078] For information regarding this technical issue, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 4 , Figure 22 and Figure 23 In one embodiment of this application, the valve box body 11 may further include a mounting member 113, which is disposed on the valve box body 111. The mounting member 113 has a mounting hole 113a that penetrates the mounting member 113. The mounting hole 113a has a fixed sub-hole 113a1 and a disassembly sub-hole 113a2 that are interconnected. The fixed sub-hole 113a1 is located on the periphery of the disassembly sub-hole 113a2, and the disassembly sub-hole 113a2 protrudes from the fixed sub-hole 113a1 on opposite sides along the cross-sectional direction. That is, the cross-section of the fixed sub-hole 113a1 has opposite sides, and the cross-section of the disassembly sub-hole 113a2 protrudes from the opposite sides of the cross-section of the fixed sub-hole 113a1. In other words, the outer dimensions of the disassembly sub-hole 113a2 are larger than the outer dimensions of the fixed sub-hole 113a1.

[0079] Specifically, the refrigerant cut-off control assembly is installed via mounting hole 113a on mounting piece 113.

[0080] The mounting component 113 is disposed on the valve box body 111 in any way. For example, the mounting component 113 can be welded to the valve box body 111. In other embodiments, the mounting component 113 and the valve box body 111 can also be fastened together by fasteners such as screws.

[0081] Please see Figure 2 The mounting component 113 may have a first positioning hole 113d, and the valve box body 111 has a first positioning element 111c, which is inserted into the first positioning hole 113d. By inserting into the first positioning hole 113d, the first positioning element 111c can position the mounting component 113, thereby facilitating welding or fastening of the mounting component 113 to the valve box body 111.

[0082] In other embodiments, the mounting member 113 may have a first positioning member 111c, and the valve box body 111 may have a first positioning hole 113d.

[0083] The number of mounting parts 113 can be determined according to the actual installation requirements. For example, the number of mounting parts 113 can be one or more.

[0084] The specific shape of the mounting component 113 is not limited; for a preferred embodiment, please refer to [reference needed]. Figure 1 , Figure 23 and Figure 24 The mounting component 113 can adopt a bent structure. The bent structure of the mounting component 113 has good structural strength and is not easily deformed by external impact.

[0085] For example, please refer to Figure 2 , Figure 4 , Figure 23 and Figure 24 The mounting component 113 can be bent to form a first mounting section 1131, a connecting section 1133, and a second mounting section 1132. The first mounting section 1131 and the second mounting section 1132 are located on opposite sides of the connecting section 1133 and extend in opposite directions. The first mounting section 1131 is connected to the valve box body 111, and the mounting hole 113a is provided in the second mounting section 1132.

[0086] By way of example, the mounting member 113 can also be bent to form a first mounting section 1131 and a second mounting section 1132 located on one side of the first mounting section 1131. The first mounting section 1131 is connected to the valve box body 111, and the mounting hole 113a is provided in the second mounting section 1132. That is, the mounting member 113 may also be without the connecting section 1133.

[0087] It should be noted that when there are multiple mounting parts 113, the structure and shape of each mounting part 113 can be the same or different.

[0088] The mounting hole 113a1 is used to mate with the connecting parts or fasteners for mounting the refrigerant cut-off control assembly.

[0089] The disassembly / removal sub-hole 113a2 is used to allow connecting parts or fasteners to pass through when disassembling or assembling the refrigerant cutoff control assembly. That is, when installing the refrigerant cutoff control assembly, the connecting parts or fasteners can first pass through the disassembly / removal sub-hole 113a2, and then enter the fixing sub-hole 113a1 from the connection between the fixing sub-hole 113a1 and the disassembly / removal sub-hole 113a2. When disassembling the refrigerant cutoff control assembly, the connecting parts or fasteners passing through the fixing sub-hole 113a1 are first moved from the connection between the fixing sub-hole 113a1 and the disassembly / removal sub-hole 113a2 into the disassembly / removal sub-hole 113a2, and then the connecting parts or fasteners are removed from the disassembly / removal sub-hole 113a2.

[0090] It should be noted that, depending on the installation method, the disassembly sub-hole 113a2 may or may not be used.

[0091] Taking the refrigerant cut-off control component being fixed to the mounting bracket by screws as an example, the mounting bracket is provided with threaded holes, and the screw has a shank with external threads and a head with a cross-sectional dimension larger than the shank.

[0092] If the refrigerant cut-off control assembly is installed on top of the mounting bracket, with the threaded hole facing upwards, when installing the refrigerant cut-off control assembly, simply align the fixing sub-hole 113a1 on the mounting hole 113a with the threaded hole, then insert the shank of the screw directly into the fixing sub-hole 113a1 and the threaded hole and tighten the screw. Similarly, when disassembling the refrigerant cut-off control assembly, simply remove the loosened screw from the fixing sub-hole 113a1 and the threaded hole. In other words, the disassembly sub-hole 113a2 is not needed for either installing or disassembling the refrigerant cut-off control assembly.

[0093] If the refrigerant cut-off control component is installed on the side of the mounting bracket, or at the bottom of the mounting bracket (essentially a suspended installation), the threaded hole is on the side or bottom of the mounting bracket. If, during installation, the installer directly aligns the fixing sub-hole 113a1 with the threaded hole before inserting the screw, the installer will need to continuously support or hold the refrigerant cut-off control component. This will be strenuous during installation and difficult for a single person to install (during disassembly of the refrigerant cut-off control component). (The same applies to components). Therefore, for refrigerant cut-off control components installed on the side or bottom of the mounting bracket, the installer can first screw the shank of the screw into the threaded hole, then align the disassembly / removal sub-hole 113a2 on the mounting hole 113a with the head of the screw, and let the head of the screw pass through the disassembly / removal sub-hole 113a2. After the head passes through the disassembly / removal sub-hole 113a2, the shank of the screw enters the disassembly / removal sub-hole 113a2. Then, by moving the refrigerant cut-off control component, the shank can enter the fixing sub-hole 113a1 from the connection between the fixing sub-hole 113a1 and the disassembly / removal sub-hole 113a2. Since the screw has already been screwed into the threaded hole on the mounting bracket, the installer does not need to hold or support the refrigerant cut-off control component; the refrigerant cut-off control component can be supported by the shank of the screw. The installer only needs to tighten the screw on this basis. Similarly, when disassembling the refrigerant cut-off control assembly, simply loosen the screws slightly, then move the refrigerant cut-off control assembly so that the shank of the screw enters the disassembly / removal sub-hole 113a2 through the connection between the fixing sub-hole 113a1 and the disassembly / removal sub-hole 113a2, and then the head of the screw comes out of the disassembly / removal sub-hole 113a2, thus removing the refrigerant cut-off control assembly.

[0094] For the refrigerant cut-off control component of this embodiment, since the mounting hole 113a on the mounting member 113 can adapt to different installation methods, the refrigerant cut-off control component can be fixed on the mounting bracket whether the mounting bracket is installed on the ground or on the wall, ceiling or suspended ceiling of the building. Therefore, the refrigerant cut-off control component of this embodiment can meet various installation requirements such as ground, wall-mounted, and suspended installation.

[0095] In some embodiments, please refer to Figure 4 , Figure 23 and Figure 24 There can be two fixing sub-holes 113a1. The two fixing sub-holes 113a1 are located on opposite sides of the disassembly sub-hole 113a2. The installer can choose one of the fixing sub-holes 113a1 for installation as needed, which can further improve the convenience of installation.

[0096] In some embodiments, please refer to Figure 23 and Figure 24The mounting component 113 may also have at least two mounting holes 113a. Compared with the mounting component 113 having one mounting hole 113a, having at least two mounting holes 113a can reduce the number of mounting components 113 and improve the efficiency of the connection between the mounting component 113 and the valve box body 111.

[0097] Please continue reading. Figure 1 and Figure 3 The first mounting port 111b is located on one side of the valve box body 111 along the first direction. In some embodiments, there may be two mounting members 113, and each mounting member 113 has at least two mounting holes 113a. The two mounting members 113 are respectively disposed on opposite sides of the valve box body 111 along the second direction, and the mounting holes 113a of each mounting member 113 are spaced apart along the third direction, with the first direction, second direction, and third direction being perpendicular. By providing two mounting members 113, and each mounting member 113 having at least two mounting holes 113a, the stability and reliability of the refrigerant cut-off control assembly installation can be improved while minimizing the number of mounting members 113.

[0098] In some embodiments, please refer to Figure 1 , Figure 17 and Figure 18 The valve box body 111 has a first through hole 111e on one side along the second direction. The mounting component 113 includes a first mounting component 113', which is located on the side of the valve box body 111 with the first through hole 111e along the second direction.

[0099] The first through hole 111e is used to pass through the connecting pipe 12, so that the connecting pipe 12 extends from inside the valve box body 111 to the outside of the valve box body 11.

[0100] The first mounting component 113' is one type of mounting component 113; the name is used to distinguish them for ease of description. Please refer to [link / reference]. Figure 2 , Figure 4 , Figure 8 , Figure 17 , Figure 18 , Figure 21 and Figure 23 Along the through direction of the mounting hole 113a, the first mounting member 113′ has a first end face 113b and a second end face 113c. The second end face 113c is located on the side of the first end face 113b facing away from the first through hole 111e along the first direction. The support portion 1134 protrudes from the first end face 113b. The support portion 1134 is used to support the connecting pipe 12 extending to the outside of the valve box body 11, so that the connecting pipe 12 can remain as stable as possible during the operation of the refrigerant cut-off control assembly.

[0101] Please see Figure 17 and Figure 21 The support part 1134 may also be provided with a pipe clamp connection hole 1134a, which is used to install the first pipe clamp 15. The first pipe clamp 15 can be connected to the mounting part 113 to constrain the connecting pipe 12 between the first pipe clamp 15 and the mounting part 113, thereby further improving the reliability of the support of the support part 1134.

[0102] Further, please refer to Figure 1 , Figure 5 and Figure 8 The valve box body 111 may also have a second through hole 111f on the side opposite to the first through hole 111e along the second direction. The mounting component 113 also includes a second mounting component 113″, which is located on the side of the valve box body 111 with the second through hole 111f along the second direction.

[0103] The first through hole 111e is also used to pass through the connecting pipe 12, so that the connecting pipe 12 extends from inside the valve box body 111 to the outside of the valve box body 11.

[0104] The second mounting part 113″ is also a type of mounting part 113, but the name is distinguished for ease of description. Compared with the first mounting part 113′, the second mounting part 113″ does not have a support part 1134.

[0105] Please see Figure 8 , Figures 11 to 13 , Figure 21 The refrigerant shut-off valve box 10 is generally equipped with a pressure relief valve 18. The pressure relief valve 18 is used to reduce the pressure in the refrigerant pipeline by opening the valve when the pressure in the refrigerant pipeline exceeds the safe value, so as to avoid safety accidents caused by excessive pressure in the refrigerant pipeline.

[0106] Figure 8 , Figures 11 to 13 , Figure 21The pressure relief valve 18 shown is located at the point where the connecting pipe 12 extends from the first through hole 111e to the outside of the valve box 11. To facilitate the installation of the pressure relief valve 18, the length of the connecting pipe 12 extending from the first through hole 111e to the outside of the valve box 11 is relatively long, making it prone to swaying during the operation of the refrigerant cut-off control component. Therefore, by providing a first mounting member 113' with a support portion 1134, this relatively long section of the connecting pipe 12 can be effectively supported, thereby reducing the swaying of the connecting pipe 12. Conversely, the length of the connecting pipe 12 extending from the second through hole 111f to the outside of the valve box 11 is relatively short, making it less prone to swaying during the operation of the refrigerant cut-off control component. In other words, this relatively short section can remain stable without support. Therefore, only a standard second mounting member 113' without the support portion 1134 needs to be provided, thereby reducing production costs.

[0107] In some embodiments, please refer to Figure 1 , Figure 3 , Figures 5 to 8 The refrigerant shut-off valve box 10 may also include a protective cover 19, which covers the pressure relief valve 18 to protect the pressure relief valve 18.

[0108] It is understood that in some other embodiments, the second mounting element 113″ may also be replaced by the first mounting element 113′.

[0109] For the electrical control box 20 located outside the valve box body 11, in some embodiments please refer to Figure 2 The electrical control box 21 may have a second positioning member 21a, and the mounting member 113 has a second positioning hole 113e. The second positioning member 21a is inserted into the second positioning hole 113e. The insertion and engagement of the second positioning member 21a and the second positioning hole 113e can position the electrical control box 21, thereby facilitating the connection between the electrical control box 21 and the valve box body 111.

[0110] In other embodiments, the electrical control box 21 may have a second positioning hole 113e, and the valve box body 111 may have a second positioning member 21a.

[0111] Further, please refer to Figure 1 , Figures 25 to 27For a refrigerant shut-off valve box 10 having multiple mounting parts 113 (there can be two or more mounting parts 113), and the multiple mounting parts 113 being respectively disposed on opposite sides of the valve box body 111 along the second direction, the electrical control box 20 can also be selectively and detachably connected to the valve box cover 112 and any side of the valve box body 111 along the third direction. That is, depending on actual installation requirements, the electrical control box 20 can be selectively installed on any side of the valve box body 111 along the third direction and detachably connected to the valve box body 111. The electrical control box 20 can also be selectively and detachably connected to the valve box cover 112, thereby meeting more installation needs.

[0112] In some embodiments, please refer to Figure 26 and Figure 27 For the electrical control box 20, which is detachably connected to the valve box cover 112, the electrical control box 20 can also have its installation orientation changed as needed. For example, the electrical control box 20 can be positioned relative to... Figure 26 The connection shown is rotated 180 degrees and becomes Figure 26 The connection configuration shown allows for further customization to meet a wider range of installation needs.

[0113] In addition, the electrical control box body 211 of the electrical control box 21 can be fastened to the valve box body 111 or the valve box cover 112 by screws or other fasteners. The various side plates that make up the electrical control box body 211, as well as the valve box cover 112 and the valve box body 111, can also be fastened together by screws or other fasteners. In some embodiments, please refer to... Figure 1 , Figures 25 to 27 The fastening holes on the electrical control box body 211 can be positioned to correspond to the fastening holes on the valve box body 111 used to fasten two adjacent side plates, or to the fastening holes used to fasten the valve box cover 112 to the valve box body 111. In other words, the same fastener can be shared between two adjacent side plates and between the electrical control box body 211 and the valve box body 111, and also between the valve box cover 112 and the valve box body 111 and between the electrical control box body 211 and the valve box cover 112. This reduces the number of fasteners and lowers production costs.

[0114] In some embodiments, please refer to Figure 6 , Figure 9 and Figure 10For the electrical control box 20 located outside the valve box body 11, the electrical control box 20 may include a water-blocking member 23. The water-blocking member 23 is disposed within the second receiving cavity 211a to separate an installation space 211a1 and a wiring space 211a2, which are at least connected by a first connecting port 23a, within the second receiving cavity 211a. The wiring space 211a2 is connected to the first wiring port 211b. The electrical control board 22 is disposed within the installation space 211a1 and is connected to the wires of the shut-off valve 13 through the first connecting port 23a and the first wiring port 211b.

[0115] In other words, the connecting wire between the electronic control board 22 and the shut-off valve 13 passes through the first connection port 23a and the first wire passage port 211b.

[0116] In some cases, water outside the control box 20 may enter the second receiving cavity 211a through the first wiring port 211b. This is especially true when the refrigerant cut-off control component is installed outdoors. In severe weather such as heavy rain, rainwater is more likely to enter the second receiving cavity 211a through the first wiring port 211b. Therefore, by setting up the water baffle 23, the control board 22 can be separated from the first wiring port 211b, which can effectively prevent external water from entering the second receiving cavity 211a through the first wiring port 211b and then flowing to the control board 22, thus providing better protection for the control board 22.

[0117] Figure 6 and Figure 9 The water-blocking member 23 shown is connected to the electrical control box 21 to jointly enclose the wire passage space 211a2. In other embodiments, the water-blocking member 23 may also surround the outer periphery of the first wire passage 211b to enclose the wire passage space 211a2.

[0118] In some embodiments, please refer to Figure 10 The water-blocking component 23 may have a flange 23b, which abuts against the part of the electrical control box 21 located on the outer periphery of the first wire passage 211b. By abutting, the gap between the water-blocking component 23 and the electrical control box 21 can be effectively prevented, thereby effectively preventing water from seeping into the installation space 211a1 through the gap between the water-blocking component 23 and the electrical control box 21.

[0119] In other embodiments, the water-blocking component 23 and the electrical control box 21 may also be an integral structure.

[0120] In some embodiments, please refer to Figure 9 and Figure 10 The height difference between the first connecting port 23a and the first wire passage port 211b along the height direction of the refrigerant cut-off control component can be greater than 0.

[0121] The height direction refers to the refrigerant cut-off control component in the installed state (reference). Figure 1 and Figure 25 The height direction of the refrigerant cut-off control component shown is such that, when the refrigerant cut-off control component is in the installed state, the position of the first connecting port 23a is higher than the position of the first wire passage port 211b. The advantage of this arrangement is that even if water flows into the wire passage space 211a2 from the first wire passage port 211b, the water is less likely to flow towards the first connecting port 23a because the first connecting port 23a is relatively higher, thus enabling the water-blocking component 23 to have a better water-blocking effect.

[0122] Preferably, please refer to Figure 9 and Figure 10 The first connecting port 23a can be located on the side opposite to the first connecting port 211b in the wiring space 211a2. This means that when the refrigerant cut-off control component is in the installation state, the first connecting port 211b is located at the bottom of the wiring space 211a2, and the first connecting port 23a is located at the top of the wiring space 211a2.

[0123] In other embodiments, the first connection port 23a may also be located on the side adjacent to the wire passage space 211a2 and the first wire passage port 211b.

[0124] Additionally, it should be noted that for a refrigerant cut-off control assembly with mounting component 113, depending on the installation method adopted by the refrigerant cut-off control assembly, the position of the first connection port 23a may not be higher than the first wiring port 211b. However, for a refrigerant cut-off control assembly installed outdoors, it is preferable to adopt an installation method in which the position of the first connection port 23a is higher than the position of the first wiring port 211b.

[0125] Please see Figure 6 , Figure 9 and Figure 10 The electrical control box body 211 includes an end plate 2111 and a side plate 2112 surrounding the outer periphery of the end plate 2111. The end plate 2111 and the side plate 2112 together enclose a second receiving cavity 211a, which is located on the side of the end plate 2111 away from the refrigerant shut-off valve box 10.

[0126] In some embodiments, please refer to Figure 6 , Figure 9 and Figure 10 The electrical control board 22 can be installed on the end plate 2111, and the first cable passage 211b can be installed on the side plate 2112.

[0127] Please see Figure 9 and Figure 10The side panel 2112 includes a first sub-wall 21121 and a second sub-wall 21122 opposite to the first sub-wall 21121. The second sub-wall 21122 is located above the first sub-wall 21121 along the height direction of the refrigerant cut-off control assembly. Preferably, please refer to [reference needed]. Figure 9 and Figure 10 The first cable passage 211b can be located on the first sub-wall 21121. That is, when the refrigerant cut-off control component is in the installed state, the first cable passage 211b faces the ground, which can better prevent water from entering the cable passage space 211a2 from the first cable passage 211b.

[0128] Further, please refer to Figure 6 The water-blocking component 23 can be spaced apart from the second sub-wall 21122, so that a second connecting port 23c is formed at the interval. The first connecting port 23a is located on the side opposite to the first wire-passing port 211b in the wire-passing space 211a2, and is connected to the installation space 211a1 through the second connecting port 23c. That is, the second connecting port 23c is located around the first connecting port 23a, and the connecting wire passes through the second connecting port 23c. This arrangement allows the water-blocking component 23 to play a good role in blocking water, and also facilitates the passage of connecting wires.

[0129] In some embodiments, please refer to Figure 6 and Figure 17 The valve box body 111 has a second wiring port 111d on one side along the second direction. The electrical control box 20 is located on one side of the valve box body 111 along the third direction. The wiring space 211a2 can be located on the side of the installation space 211a1 along the second direction close to the second wiring port 111d. The wiring path connecting the cut-off valve 13 and the electrical control board 22 passes through the second wiring port 111d.

[0130] In other words, the second wire passage 111d is a hole on the valve box body 111 for the connecting wire to pass through. The wire passage space 211a2 can be set close to the second wire passage 111d, thereby reducing the length of the connecting wire exposed outside the refrigerant cut-off valve box 10 and the electrical control box 20. This not only makes the appearance of the refrigerant cut-off control component relatively aesthetically pleasing, but also reduces the risk of damage to the exposed parts of the connecting wire.

[0131] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 8The connecting pipe 12 can extend from the side of the valve box body 111 where the second wire passage port 111d is provided to the outside of the valve box body 111. The pressure relief valve 18 is provided at the part where the connecting pipe 12 extends to the outside of the valve box body 111 (i.e., the pressure relief valve 18 is provided at the part where the connecting pipe 12 extends from the side of the valve box body 111 where the second wire passage port 111d is provided to the outside of the valve box body 111). For the refrigerant cut-off valve box 10 with a protective cover 19, the wire path passes through the opening of the protective cover 19. That is to say, the connecting wire passes through the inside of the protective cover 19 and extends out from the opening of the protective cover 19.

[0132] In addition to shielding and protecting the pressure relief valve 18, the protective cover 19 also serves to block the second wiring port 111d, thus effectively preventing external water from entering the valve box 11 through the second wiring port 111d. Furthermore, since a portion of the connecting wire extending from the second wiring port 111d to the outside of the valve box 11 is located inside the protective cover 19, the cover 19 also provides some protection for the connecting wire. This further enhances the aesthetics of the refrigerant cut-off control assembly and reduces the risk of damage to exposed parts of the connecting wire.

[0133] In some embodiments, please refer to Figure 1 , Figure 9 and Figure 10 The electrical control box 20 may also include a wire-passing rubber ring 24. The wire-passing rubber ring 24 includes a sealing section 241 and an extension section 242 having a wire-passing channel 242a. The sealing section 241 includes a sealing body 2411 having a wire-passing through hole 142a and a baffle 2412 that blocks the wire-passing through hole 142a. The baffle 2412 can be reversibly opened under external force. The sealing body 2411 is sealed at the first wire-passing opening 211b, and the extension section 242 is located on the side of the sealing section 241 away from the wire-passing space 211a2. The wire-passing channel 242a communicates with the wire-passing through hole 142a.

[0134] Specifically, the wire-passing rubber ring 24 is used to seal the first wire-passing opening 211b to prevent external water from entering the wire-passing space 211a2 as much as possible. The wire-passing through hole 142a is used for threading the connecting wire. When no connecting wire is threaded, the baffle 2412 blocks the through hole 142a. During the threading of the connecting wire, the baffle 2412 is reversibly expanded under the force of the connecting wire. The expanded baffle 2412, through contact with the connecting wire, still provides some water-blocking effect. The wire-passing channel 242a of the extension section 242 is also used for the passage of the connecting wire. The extension section 242 can, to a certain extent, prevent external water from flowing towards the first wire-passing opening 211b, thereby improving the sealing performance of the wire-passing rubber ring 24.

[0135] Please continue reading. Figure 9 and Figure 10 In some embodiments, the cross-sectional area of ​​the wire passage 242a can gradually increase from the end of the extension section 242 near the sealing section 241 to the end away from the sealing section 241. That is, the inner wall surface of the wire passage 242a has a certain inclination angle. Thus, even if external water flows into the wire passage 242a, most of the water can flow out along the inner wall surface of the wire passage 242a to the outside of the wire passage 242a, thereby better preventing external water from flowing to the first wire passage 211b.

[0136] In some embodiments, the extension 242 can also be bound to create an elastic deformation that closes the wire passage 242a. That is, the extension 242 can be made of a flexible material, and the extension 242 can be bound with ropes, cable ties, etc. After binding, the extension 242 creates an elastic deformation to close the wire passage 242a, thereby effectively preventing external water from entering the wire passage 242a, and further improving the sealing performance of the wire passage rubber ring 24.

[0137] In related technologies, since at least part of the connecting pipe structure is located inside the valve box, condensation will occur inside the valve box due to the temperature difference between the inside and outside of the connecting pipe when the cooler refrigerant passes through it. Some of this condensation will seep out to the outside of the valve box and drip down its sides. Therefore, users need to add a water collection device to collect and / or drain the condensation, resulting in a poor user experience.

[0138] For information regarding this technical issue, please refer to [link / reference]. Figure 5 , Figure 8 , Figures 11 to 16 In one embodiment of this application, the refrigerant shut-off valve box 10 may also be provided with a heat insulation component 14, which is disposed in the first receiving cavity 111a and at least covers the connecting pipe 12.

[0139] Insulation component 14 includes, but is not limited to, materials with insulation function such as foam.

[0140] Figure 8 The insulation component 14 shown not only wraps the connecting pipe 12, but also the shut-off valve 13. In some other embodiments, the insulation component 14 may only wrap the connecting pipe 12.

[0141] For the insulation component 14 that encloses the shut-off valve 13, please refer to Figure 19 and Figure 20The interior of the insulation component 14 may have a wire passage 141a that communicates with the outside. The wire passage path connecting the shut-off valve 13 and the electrical control board 22 passes through the wire passage 141a. In other words, the connecting wire between the electrical control board 22 and the shut-off valve 13 passes through the wire passage 141a to achieve electrical connection with the shut-off valve 13.

[0142] It should be noted that the "wrapping" mentioned in this application mainly refers to the part of the connecting pipe 12 and other components being wrapped being located inside the insulation component 14, rather than the wrapped part having to be in contact with the insulation component 14.

[0143] The insulation component 14 can insulate and isolate the connecting pipe 12 by at least wrapping it. Almost no condensation will be generated inside the valve box 11. Therefore, by setting the insulation component 14, condensation can be effectively prevented from being generated in the refrigerant cut-off valve box 10, thereby improving the user experience.

[0144] In some embodiments, please refer to Figure 5 , Figure 8 and Figure 11 The insulation component 14 may include a first insulation structure 1411 and a second insulation structure 1412. The first insulation structure 1411 is located on the side of the connecting pipe 12 away from the first mounting port 111b of the valve box body 111. The second insulation structure 1412 is located on the side of the connecting pipe 12 close to the first mounting port 111b. The first insulation structure 1411 and the second insulation structure 1412 are detachably connected so as to at least wrap the connecting pipe 12 between the first insulation structure 1411 and the second insulation structure 1412.

[0145] In other words, the insulation component 14 can be composed of at least a first insulation structure 1411 and a second insulation structure 1412. The first insulation structure 1411 and the second insulation structure 1412 can be separated from each other. Since the second insulation structure 1412 is located on the side of the connecting pipe 12 near the first mounting port 111b, the second insulation structure 1412 can be taken out from the first mounting port 111b or placed into the first receiving cavity 111a from the first mounting port 111b.

[0146] Figure 5 , Figure 8 and Figure 11 The shut-off valve 13 shown is also wrapped between the first insulation structure 1411 and the second insulation structure 1412. In some other embodiments, the first insulation structure 1411 and the second insulation structure 1412 may only wrap the connecting pipe 12 and not the shut-off valve 13.

[0147] The advantage of setting up a detachable first insulation structure 1411 and a second insulation structure 1412 is that after the second insulation structure 1412 is removed from the first mounting port 111b, the components such as the connecting pipe 12 wrapped by the insulation component 14 can be inspected. After the inspection is completed, the second insulation structure 1412 can be put back into the first receiving cavity 111a from the first mounting port 111b and re-wrap the connecting pipe 12 and other components by connecting it with the first insulation structure 1411. This improves the convenience of maintenance of the refrigerant shut-off valve box 10.

[0148] For the insulation component 14 that encloses the shut-off valve 13, please refer to Figure 19 and Figure 20 Since it is generally not necessary to remove the first insulation structure 1411, the wire channel 141a can be set on the first insulation structure 1411 and located on the side of the first insulation structure 1411 close to the second insulation structure 1412, so as to facilitate the fixing of the wire connection.

[0149] Please continue reading. Figure 19 and Figure 20 The wire guide 141a has an opening on the side near the second insulation structure 1412, the opening for inserting connecting wires into the wire guide 141a. The opening has opposing first and second edges; in some embodiments, please refer to... Figure 19 and Figure 20 The first insulation structure 1411 may also have a first baffle portion 141b and a second baffle portion 141c disposed at the opening. The first baffle portion 141b extends from the first edge to the second edge and is spaced apart from the second edge, and the second baffle portion 141c extends from the second edge to the first edge and is spaced apart from the first edge.

[0150] The connecting wire can enter the wire groove 141a from the gap between the first wire-blocking part 141b and the second edge, and from the gap between the second wire-blocking part 141c and the first edge. After the connecting wire enters the wire groove 141a, the first wire-blocking part 141b and the second wire-blocking part 141c can prevent the connecting wire from coming out of the opening, thereby effectively preventing the connecting wire from coming out of the opening and affecting the connection between the first insulation structure 1411 and the second insulation structure 1412, and thus improving the reliability of the connection between the first insulation structure 1411 and the second insulation structure 1412.

[0151] In some embodiments, please refer to Figure 8 , Figures 12 to 15The connecting pipe 12 may have a bent section 12a, which is located in the first receiving cavity 111a and bends toward the first mounting port 111b. The first insulation structure 1411 may also have a boss portion 14112 protruding toward the first mounting port 111b. The bent section 12a abuts against the boss portion 14112, and the shut-off valve 13 is disposed in the bent section 12a.

[0152] The connecting pipe 12 is provided with a bend section 12a, and the shut-off valve 13 is located in the bend section 12a. This allows the shut-off valve 13 to be as close as possible to the first mounting port 111b, which facilitates the maintenance of the shut-off valve 13. The first insulation structure 1411 is provided with a boss portion 14112, which can provide support for the bend section 12a so that the bend section 12a can remain stable.

[0153] For the shut-off valve 13, which is also enclosed in the refrigerant shut-off valve box 10 between the first insulation structure 1411 and the second insulation structure 1412, please refer to some embodiments. Figure 8 , Figure 11 , Figure 12 , Figure 15 and Figure 16 The second insulation structure 1412 may include a separable first insulation part 14121 and a second insulation part 14122. The second insulation is located on the side of the shut-off valve 13 near the first mounting port 111b to shield the shut-off valve 13.

[0154] Figure 8 and Figure 11 The connecting pipe 12 shown has its two ends along its extension direction located on opposite sides of the first receiving cavity 111a along the second direction of the valve box body 11. The first insulation part 14121 is located on one side of the shut-off valve 13 along the second direction. The second insulation part 14122 is actually detachably connected to both the first insulation part 14121 and the first insulation structure 1411. In other embodiments, the first insulation part 14121 may be detachably connected to the first insulation structure 1411, and the second insulation part 14122 may be located on the side of the first insulation part 14121 away from the first insulation structure 1411. This is equivalent to the second insulation part 14122 being detachably connected only to the first insulation part 14121, and not detachably connected to the first insulation structure 1411.

[0155] In other words, the second insulation structure 1412 can also be composed of at least a first insulation part 14121 and a second insulation part 14122. The first insulation part 14121 and the second insulation part 14122 can be connected separately. The second insulation part 14122 is mainly used to shield the shut-off valve 13. Without removing the first insulation part 14121, the shut-off valve 13 can be exposed simply by removing the second insulation part 14122 from the first mounting port 111b. Compared with the connecting pipeline 12, the shut-off valve 13 is maintained more frequently. Therefore, by providing the first insulation part 14121 and the second insulation part 14122 in the second insulation structure 1412, only the second insulation part 14122 needs to be removed when maintaining the shut-off valve 13, thereby further improving the convenience of maintenance.

[0156] In some embodiments, please refer to Figure 8 , Figure 16 and Figure 19 The insulation component 14 may have a limiting channel 14a. Figure 8 , Figure 16 and Figure 19 The limiting channel 14a shown is formed by a first limiting groove 14a1 provided in the first insulation structure 1411 and a second limiting groove 14a2 provided in the second insulation structure 1412. In some other embodiments, the limiting channel 14a may be provided only in the first insulation structure 1411 or only in the second insulation structure 1412.

[0157] Please continue reading. Figure 8 , Figure 12 and Figure 21 The connecting pipe 12 engages with the limiting channel 14a, meaning that at least a portion of the connecting pipe 12 encased in the insulation component 14 is inserted into the limiting channel 14a for restraint. This arrangement effectively secures the connecting pipe 12, preventing displacement or torsion of the shut-off valve 13 during connection with the refrigerant line, and also preventing vibration of the connecting pipe 12 during air conditioner operation, thus providing effective noise and vibration reduction.

[0158] In order to improve the limiting effect of the limiting channel 14a, the limiting channel 14a preferably adopts a shape that matches the shape of the connecting pipe 12. That is to say, the limiting channel 14a can be a contour channel.

[0159] For the refrigerant shut-off valve box 10 with a bend 12a in the connecting pipe 12 and a boss 14112 in the first insulation structure 1411, please refer to the example. Figure 16 and Figure 19The first insulation structure 1411 may have a first limiting groove 14a1, and the second insulation structure 1412 may have a second limiting groove 14a2. A portion of the first limiting groove 14a1 is located in the main body portion 14111, and another portion of the first limiting groove 14a1 is located in the boss portion 14112. Please refer to [link / reference]. Figure 19 For the second insulation structure 1412, which is at least composed of the first insulation portion 14121 and the second insulation portion 14122, the second limiting groove 14a2 may be partially located in the first insulation portion 14121 and partially located in the second insulation portion 14122. That is, the bent segment 12a can also be limited by the limiting channel 14a, so that the bent segment 12a can more reliably abut against the boss portion 14112.

[0160] For the refrigerant shut-off valve box 10 where the shut-off valve 13 is enclosed between the first insulation structure 1411 and the second insulation structure 1412, in some embodiments, please refer to Figure 13 , Figure 14 , Figure 16 , Figure 19 The insulation component 14 may have a limiting groove 14b. Figure 16 , Figure 19 The limiting groove 14b shown is formed by the third limiting groove 14b1 provided in the first thermal insulation structure 1411 and the fourth limiting groove 14b2 provided in the second thermal insulation structure 1412.

[0161] In other embodiments, the limiting groove 14b may be provided only in the first insulation structure 1411, or only in the second insulation structure 1412.

[0162] Please continue reading. Figure 13 and Figure 21 The shut-off valve 13 engages with the limiting groove 14b, meaning that at least a portion of the shut-off valve 13 is located within the limiting groove 14b for limiting its position. This arrangement effectively secures the shut-off valve 13, thus preventing displacement or torsion of the shut-off valve 13 during the connection of the connecting pipe 12 to the refrigerant pipe.

[0163] Further, please refer to Figure 8 and Figure 13The shut-off valve 13 may include a connecting column 131 and a valve body 132 disposed at one end of the connecting column 131. The shut-off valve 13 is connected to the connecting pipeline 12 through the connecting column 131. The shut-off valve 13 may be configured to engage with the connecting column 131 and the limiting groove 14b. That is, the shut-off valve 13 may be configured to have the connecting column 131 inserted into the limiting groove 14b, while the valve body 132 is located outside the limiting groove 14b. Since the connecting column 131 has a relatively regular shape, the engagement of the connecting column 131 with the limiting groove 14b facilitates the machining of the limiting groove 14b.

[0164] Additionally, for the connecting pipe 12 having a bend 12a, the first insulation structure 1411 has a boss 14112, and the second insulation structure 1412 has a refrigerant shut-off valve box 10 with a first insulation portion 14121 and a second insulation portion 14122. For example, please refer to [link to relevant documentation]. Figure 16 and Figure 19 The boss portion 14112 may have a third limiting groove 14b1, and the first heat insulation portion 14121 may have a fourth limiting groove 14b2. That is to say, the boss portion 14112 and the first heat insulation portion 14121 may cooperate to form a limiting groove 14b, without the need to provide a fourth limiting groove 14b2 on the second heat insulation portion 14122.

[0165] In some embodiments, please refer to Figure 8 , Figure 18 , Figure 19 and Figure 21 The insulation component 14 can also be limited to the first receiving cavity 111a. That is, the insulation component 14 can be constrained within the first receiving cavity 111a, thereby ensuring that the position of the insulation component 14 will not shift, and thus improving the reliability of the insulation component 14 wrapping the connecting pipe 12.

[0166] by Figure 11 Taking the refrigerant shut-off valve box 10 shown as an example, the insulation component 14 can be limited in at least one of the second and third directions by cooperating with the first receiving cavity 111a.

[0167] For example, please refer to Figure 8 , Figure 11 , Figure 12 , Figure 18 The insulation component 14 may be provided with a first limiting part 142 having a through hole 142a on at least one side along the second direction. The valve box body 111 has a first through hole 111e corresponding to the first limiting part 142. The first limiting part 142 passes through the first through hole 111e. The connecting pipe 12 passes through the through hole 142a to extend to the outside of the valve box body 11.

[0168] In other words, a first limiting part 142 with a through hole 142a can be provided on each of the opposite sides of the insulation component 14 along the second direction, or a first limiting part 142 with a through hole 142a can be provided only on one of the opposite sides of the insulation component 14 along the second direction. The number and setting position of the first through holes 111e on the valve box body 111 correspond to the first limiting part 142. The first limiting part 142 passes through the first through hole 111e, and the connecting pipe 12 passes through the through hole 142a to extend to the outside of the valve box body 11.

[0169] The first limiting part 142 is inserted into the first through hole 111e. In addition to limiting the insulation member 14 in the third direction, it can also limit the insulation member 14 in the first direction. In addition, the first limiting part 142 also seals the first through hole 111e, thereby effectively preventing external water from seeping into the first receiving cavity 111a through the first through hole 111e.

[0170] Further, please refer to Figure 11 and Figure 19 The insulation component 14 includes an insulation body 141 located within the first receiving cavity 111a, which is used to at least wrap the connecting pipe 12. On a projection plane perpendicular to the second direction, a portion of the projection of the insulation body 141 may lie outside the projection area of ​​the first through hole 111e. That is, after the first limiting part 142 passes through the first through hole 111e, a portion of the insulation body 141 faces the portion of the valve box body 111 located around the first through hole 111e, thereby limiting the insulation component 14 in the second direction using the insulation body 141.

[0171] For the insulation component 14 having a first insulation structure 1411 and a second insulation structure 1412, the first insulation structure 1411 and the second insulation structure 1412 are equivalent to forming part of the insulation body 141. Figure 11 A portion of the first limiting part 142 and a portion of the through hole 142a are located in the first insulation structure 1411, and another portion of the first limiting part 142 and another portion of the through hole 142a are located in the second insulation structure 1412. In some other embodiments, the first limiting part 142 may be provided only in the first insulation structure 1411 or only in the second insulation structure 1412.

[0172] For an insulation member 14 that relies on the insulation body 141 to limit the insulation element 14 in the second direction, please refer to the example. Figure 11 and Figure 19 On the projection plane perpendicular to the second direction, at least one of the first insulation structure 1411 and the second insulation structure 1412 may be partially projected outside the projection area of ​​the first through hole 111e.

[0173] In addition, for Figure 8 The refrigerant shut-off valve box 10 shown has an insulation member 14 with a first limiting portion 142 having a through hole 142a on one side of each of the two opposite sides along the second direction. The valve box body 111 has a second through hole 111f on the side opposite to the first through hole 111e along the second direction. The connecting pipe 12 extends outwards through the through hole 142a and the second through hole 111f at opposite ends along its extension direction. The refrigerant shut-off valve box 10 also includes a flexible wrapping member covering the outer surface of the connecting pipe 12. The flexible wrapping member includes, but is not limited to, a sponge. The flexible wrapping member passes through the second through hole 111f to seal it. In other words, the side of the insulation member 14 opposite to the first limiting portion 142 along the second direction does not pass through the second through hole 111f; instead, the second through hole 111f is sealed by the flexible wrapping member covering the outer surface of the connecting pipe 12. This configuration can effectively seal the second through hole 111f and also simplify the structure of the insulation component 14.

[0174] For example, please refer to Figure 8 , Figure 16 and Figure 19 The valve box body 11 may also include a limiting boss 16 disposed in the first receiving cavity 111a. The limiting boss 16 is located on the side of the first receiving cavity 111a opposite to the first mounting port 111b along the first direction. The heat insulation member 14 may include a second limiting part 143, which has a limiting port 143a extending along the first direction.

[0175] For the insulation component 14 having a first insulation structure 1411 and a second insulation structure 1412, please refer to the example. Figure 19 The second limiting part 143 can be provided on the first insulation structure 1411.

[0176] Please continue reading. Figure 19 The limiting boss 16 is located within the limiting opening 143a. That is to say, by extending into the limiting opening 143a, the limiting boss 16 can limit the insulation component 14 in a third direction.

[0177] Further, please refer to Figure 11 and Figure 19 The first receiving cavity 111a may be provided with a limiting boss 16 located outside the heat insulation member 14 on at least one side along the second direction. The heat insulation member 14 may include a heat insulation body 141, and the second limiting part 143 may be provided on the outer surface of the heat insulation body 141.

[0178] For the insulation component 14 having the first insulation structure 1411 and the second insulation structure 1412, please refer to Figure 11 and Figure 19 The second limiting part 143 can be disposed on the outer surface of the first heat insulation structure 1411, and the second limiting part 143 protrudes from the second heat insulation structure 1412 in the second direction.

[0179] Please continue reading. Figure 8 and Figure 21 The limiting port 143a extends through the second limiting part 143 in the first direction. The refrigerant shut-off valve box 10 may also include a second pipe clamp 17. The second pipe clamp 17 is connected to the limiting boss 16 to constrain the connecting pipe 12 between the limiting boss 16 and the second pipe clamp 17. That is, the limiting boss 16 can also be used to fix the second pipe clamp 17. The second pipe clamp 17 can fix the connecting pipe 12 by connecting with the limiting boss 16. Thus, the vibration of the connecting pipe 12 can be reduced during the operation of the air conditioner.

[0180] In some embodiments, please refer to Figure 12 and Figure 19 The insulation component 14 may include an insulation body 141 and two third limiting parts 144. The two third limiting parts 144 are located on opposite sides of the insulation body 141 along the first direction and protrude from the insulation body 141 in the first direction. The valve box body 111 has two folded edges 111g. The two folded edges 111g are located on opposite sides of the first mounting port 111b along the first direction, and the folded edges 111g have clearance notches 111h corresponding to the third limiting parts 144. The insulation body 141 and the third limiting parts 144 enter and exit the first receiving cavity 111a through the first mounting port 111b and the clearance notches 111h, respectively.

[0181] Specifically, the valve box cover 112 can rest against the two folded edges 111g, or it can be fastened to the two folded edges 111g by screws or other fasteners. However, due to the presence of the two folded edges 111g, the size of the insulation body 141 in the first direction is correspondingly smaller than the size of the first receiving cavity 111a in the first direction. This means that there is a large gap between the insulation body 141 and the side wall of the first receiving cavity 111a in the first direction, and the insulation body 141 cannot be limited in the first direction. Therefore, by providing two third limiting parts 144 that protrude from the insulation body 141 in the first direction, after the insulation body 141 and the third limiting parts 144 enter the first receiving cavity 111a, the third limiting parts 144 are located in the gap formed between the insulation body 141 and the side wall of the first receiving cavity 111a in the first direction, thereby enabling the insulation body 141 to be effectively limited in the first direction.

[0182] For the insulation component 14 having the first insulation structure 1411 and the second insulation structure 1412, please refer to Figure 12The first insulation structure 1411 and the second insulation structure 1412 enter and exit the first receiving cavity 111a through the first mounting port 111b. A part of the third limiting part 144 can be disposed on the first insulation structure 1411, and another part of the third limiting part 144 can be disposed on the second insulation structure 1412, so that the first insulation structure 1411 and the second insulation structure 1412 can be effectively limited in the first direction.

[0183] In other embodiments, the valve box body 11 may include two fourth limiting portions located within the first receiving cavity 111a. These two fourth limiting portions are located on opposite sides of the first receiving cavity 111a along a first direction and protrude from the same-side flange 111g along the first direction. The insulation member 14 has limiting notches on opposite sides along the first direction, and the fourth limiting portions are located within the corresponding limiting notches. In other words, the fourth limiting portions, in conjunction with their corresponding limiting notches, can also effectively limit movement in the first direction.

[0184] For the insulation component 14 having a first insulation structure 1411 and a second insulation structure 1412, please refer to some embodiments. Figure 9 and Figure 22 The second insulation structure 1412 can also extend to the first mounting port 111b. That is, the second insulation structure 1412 can be flush with or approximately flush with the first mounting port 111b. Thus, after the valve box cover 112 is closed, the second insulation structure 1412 can be limited by the valve box cover 112, thereby better preventing the second insulation structure 1412 from separating from the first insulation structure 1411 during the handling or installation of the refrigerant cut-off control component.

[0185] Please continue reading. Figure 9 and Figure 22 In some embodiments, the second insulation structure 1412 may have a cavity 1412a, which is recessed in a direction away from the first mounting opening 111b. Providing the cavity 1412a can save material of the second insulation structure 1412 and also facilitate the demolding of the second insulation structure 1412.

[0186] It is understandable that the first insulation structure 1411 and the second insulation structure 1412 form a wrapping space for components such as the connecting pipe 12, while the cavity 1412a is not connected to the wrapping space.
