Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and in particular to a refrigerant cut-off control component and an air conditioner. Background Technology

[0002] In related technologies, some air conditioners have a refrigerant shut-off control component installed on the refrigerant pipeline connecting the indoor and outdoor units. 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.

[0003] However, the refrigerant shut-off control components in related technologies require adjustments to the position of the electrical control box on the refrigerant shut-off valve box according to the installation environment, which leads to inconvenience in installation. In addition, the overall size of the refrigerant shut-off control components is relatively large, occupying a lot of installation space. Utility Model Content

The valve box body has a first receiving cavity and a first mounting port communicating with the first receiving cavity. The valve box cover is closably disposed on the first mounting port. The electrical control box is exposed at the first mounting port. The connecting pipeline is located on the side of the electrical control box away from the first mounting port.

[0013] The insulation component includes a separable first insulation structure and a second insulation structure. The first insulation structure is located on the side of the connecting pipe away from the electrical control box, and the second insulation structure is located on the side of the connecting pipe closer to the electrical control box; and / or,

The insulation component has a first wire passage and a first wire passage channel that communicates with the first wire passage and is located inside the insulation component. The electrical control box has a second wire passage that communicates with the second receiving cavity. Both the first wire passage and the second wire passage are connected to the external environment outside the refrigerant shut-off valve box, so that the wire path for connecting the shut-off valve and the electrical control board passes outside the refrigerant shut-off valve box.

[0015] In some embodiments, the second insulation structure includes a separable first insulation portion and a second insulation portion, the second insulation portion being exposed at the first mounting port, and the shut-off valve being located on the side of the second insulation portion opposite to the first mounting port.

[0016] In some embodiments, the second insulation portion has a gripping structure on the side near the first mounting port.

[0017] In some embodiments, the refrigerant cut-off control assembly further includes a first wire-passing rubber ring having a second wire-passing channel, the refrigerant cut-off valve box having a third wire-passing port, the first wire-passing rubber ring being sealed through the second wire-passing port and the third wire-passing port, and the second wire-passing channel communicating with the second receiving cavity and the external environment, respectively.

[0018] In some embodiments, the electrical control box has a fourth wiring port communicating with the second receiving cavity, the refrigerant shut-off valve box has a fifth wiring port, and the refrigerant shut-off control assembly further includes a second wiring rubber ring, the second wiring rubber ring including a sealing ring with a wiring through hole and a baffle blocking the wiring through hole, the baffle being reversibly expandable under external force; the sealing ring is sealed at the fifth wiring port, and the wiring through hole is communicating with the fourth wiring port at least after the baffle is expanded.

The refrigerant cut-off control component houses the electrical control box within the first receiving cavity of the valve box body, eliminating the need to adjust the installation position of the electrical control box according to the installation environment. This also reduces the space occupied by the electrical control box, thereby reducing the overall size of the refrigerant cut-off control component and consequently reducing the installation space it occupies. Therefore, the refrigerant cut-off control component in this application is not only easy to install but also has a relatively small overall size. Attached Figure Description

Detailed Implementation

[0043] In the description of the embodiments in this application, it should be noted that the term "height direction" is based on the attached... Figure 10 The 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.

[0044] This application provides an air conditioner, which includes an indoor unit, an outdoor unit, a refrigerant cut-off control component, and refrigerant piping.

[0045] Please see Figures 1 to 13 The refrigerant shut-off control assembly includes a refrigerant shut-off valve box 10 and an electrical control box 20.

[0046] 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.

[0047] Specifically, please refer to Figures 1 to 13The refrigerant shut-off valve box 10 includes a valve box body 11 with a first receiving cavity 111a, a shut-off valve 12, and a connecting pipe 13. At least a portion of the connecting pipe 13 is located within the first receiving cavity 111a; that is, the entire connecting pipe 13 can be located within the first receiving cavity 111a, or it can be as follows: Figure 1 A portion of the connecting pipe 13 shown is located inside the first receiving cavity 111a, and another portion of the connecting pipe 13 extends outside the valve box body 11.

[0048] The connecting pipe 13 is used to connect to the refrigerant pipe. That is to say, the indoor unit, the outdoor unit and the connecting pipe 13 are connected through the refrigerant pipe. The refrigerant circulating along the refrigerant pipe flows through the connecting pipe 13 of the refrigerant shut-off valve box 10.

[0049] It is understandable that for the refrigerant shut-off valve box 10, where the entire connecting pipeline 13 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 13 and the refrigerant pipeline are connected through the connection port.

[0050] Please see Figure 1 , Figure 3 and Figure 5 The shut-off valve 12 is located in the first receiving cavity 111a and is provided in the connecting pipe 13 for opening or closing the connecting pipe 13. That is, the shut-off valve 12 can cut off the passage in the connecting pipe 13 to prevent the refrigerant from flowing, or it can open the passage in the connecting pipe 13 to allow the refrigerant to flow normally.

[0051] For example, Figure 1 , Figure 3 and Figure 5 The refrigerant shut-off valve box 10 can be equipped with two separate connecting pipes 13, which are spaced apart, and each connecting pipe 13 is equipped with a shut-off valve 12.

[0052] Please see Figure 1 , Figure 3 , Figure 9 , Figure 10 and Figure 13 The control box 20 is disposed in the first receiving cavity 111a. 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 12.

[0053] The electronic control board 22 is used to control the opening or closing of the shut-off valve 12, thereby enabling or disabling the connecting pipe 13. During the operation of the air conditioner, if a refrigerant leak occurs, the electronic control board 22 controls the shut-off valve 12 to close according to the signal, causing the connecting pipe 13 to switch from the open state to the shut-off state. The refrigerant cannot flow in the connecting pipe 13 and the refrigerant pipe. At this time, even if there is a leak point in the indoor unit, only a small amount of refrigerant will leak from the indoor side of the refrigerant pipe, thus greatly reducing the amount of refrigerant leakage.

[0054] In related technologies, the electrical control box is installed on the outside of the valve box body. The installation position of the electrical control box needs to be adjusted according to the actual installation environment. For example, the electrical control box can be installed on the side, top or bottom of the valve box body. At the same time, the overall size of the electrical control box and the refrigerant shut-off valve box is relatively large, and installing the electrical control box on the outside of the valve box body will result in occupying more installation space.

[0055] In this embodiment, the refrigerant cut-off control component houses the electrical control box 20 within the first receiving cavity 111a of the valve box body 11. Compared to related technologies where the electrical control box is located outside the valve box body, this eliminates the need to adjust the installation position of the electrical control box 20 according to the installation environment. Furthermore, it reduces the space occupied by the electrical control box 20, thereby reducing the overall size of the refrigerant cut-off control component and consequently reducing the installation space required. Therefore, the refrigerant cut-off control component in this embodiment is not only easy to install but also has a relatively small overall size.

[0056] Furthermore, since the control box 20 is located within the first receiving cavity 111a, the valve box body 11 can prevent rainwater and other liquids from entering the first receiving cavity 111a, thereby reducing the possibility of rainwater contacting the control board 22 and providing the control board 22 with the first layer of waterproof protection. Simultaneously, since the control board 22 is also located within the control box body 21, even if a small amount of rainwater enters the first receiving cavity 111a, it will be blocked by the control box body 21 and will not be able to contact the internal control board 22, thus forming a second layer of waterproof protection. In other words, by placing the control box 20 within the first receiving cavity 111a, the control box 20 can achieve a better waterproof effect.

[0057] In some embodiments, please refer to Figures 1 to 10 , Figure 13The valve box body 11 may include 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. The electrical control box 20 is exposed at the first mounting port 111b, and the connecting pipe 13 is located on the side of the electrical control box 20 away from the first mounting port 111b. After the valve box cover 112 is closed, the valve box cover 112 covers the first mounting port 111b, so that the first receiving cavity 111a forms a relatively closed space.

[0058] In other words, the valve box cover 112 is detachably connected to the valve box body 11 for easy after-sales maintenance. At the same time, by exposing the electrical control box 20 at the first mounting port 111b, it is convenient for staff to wire and maintain the electrical control board 22.

[0059] In some embodiments, please refer to Figure 1 , Figures 4 to 7 The valve box body 11 may include a mounting bracket 113 disposed in the first receiving cavity 111a, and the electrical control box 20 is connected to the mounting bracket 113.

[0060] Mounting bracket 113 is used to install and fix the electrical control box 20 to prevent the electrical control box 20 from shifting or shaking within the first receiving cavity 111a.

[0061] The mounting bracket 113 can be installed in any location; please refer to [link / reference]. Figure 1 , Figures 4 to 7 The mounting bracket 113 is located on the inner wall adjacent to the first mounting cavity and the first mounting port 111b, and is located between the electrical control box 20 and the connecting pipe 13. Therefore, it can not affect the maintenance of the electrical control box 20, nor occupy the installation space of the connecting pipe 13.

[0062] The connection method between the mounting bracket 113 and the electrical control box 20 is not limited. For example, the mounting bracket 113 and the electrical control box 20 can be detachably connected, such as by snap-fitting or fastening with fasteners such as screws and bolts. The mounting bracket 113 and the electrical control box 20 can also be non-detachably connected, such as by welding or bonding.

[0063] In some embodiments, please refer to Figure 1 , Figures 3 to 10 , Figure 13 The refrigerant shut-off valve box 10 may also include an insulation element 114 disposed in the first receiving cavity 111a, the insulation element 114 at least covering the connecting pipe 13, and the electrical control box 20 located outside the insulation element 114.

[0064] The insulation component 114 is used to slow down the heat transfer between the connecting pipe 13 and the air, reducing the formation of condensate. For example, when the air conditioner is running and the low-temperature refrigerant flows in the connecting pipe 13, the insulation component 114 wraps around the outer periphery of the connecting pipe 13, preventing the high-temperature outside air from directly contacting the connecting pipe 13. This reduces the amount of water vapor in the first receiving cavity 111a from condensing on the outer surface of the connecting pipe 13, thus preventing the control board 22 from being damaged by moisture.

[0065] The material of the insulation component 114 is not limited. For example, the insulation component 114 can be a foam component. The foam component can effectively prevent heat conduction, heat convection and heat radiation, and has good thermal insulation performance. At the same time, the foam component has a low density and will not significantly increase the overall weight of the refrigerant cut-off control component, which facilitates the transportation and installation of the refrigerant cut-off control component.

[0066] For example, please refer to Figure 1 , Figures 3 to 10 In addition to covering the connecting pipe 13, the insulation component 114 also covers the shut-off valve 12. In some other embodiments, the insulation component 114 may only cover the connecting pipe 13.

[0067] For example, please refer to Figure 3 The electrical control box 20 can be supported by the insulation component 114. In other words, the insulation component 114 can support the electrical control box 20 to improve the installation stability of the electrical control box 20.

[0068] picture Figures 3 to 10 The mounting bracket 113 is located between the insulation component 114 and the electrical control box 20. In other words, while the electrical control box 20 is attached to the insulation component 114, it is also fixed by the mounting bracket 113, which can further improve the installation stability of the insulation component 114.

[0069] In some embodiments, please refer to Figure 1 , Figures 4 to 10 In the embodiment where the valve box body 11 includes the valve box body 111 and the valve box cover 112, the insulation component 114 may include a separable first insulation structure 1141 and a second insulation structure 1142. The first insulation structure 1141 is located on the side of the connecting pipe 13 away from the electrical control box 20, and the second insulation structure 1142 is located on the side of the connecting pipe 13 close to the electrical control box 20.

[0070] In other words, the insulation component 114 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 13 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.

[0071] Figure 1 , Figures 4 to 10 The shut-off valve 12 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 13 and not the shut-off valve 12.

[0072] In other words, the first insulation structure 1141 is located at the bottom of the first receiving cavity 111a, and the second insulation structure 1142 is located on the side of the first insulation structure 1141 near the first mounting port 111b. The first insulation component 114 and the second insulation component 114 together wrap the connecting pipe 13. By providing the separable first insulation structure 1141 and the second insulation structure 1142, the assembly of the refrigerant cut-off control component can be facilitated.

[0073] Please see Figure 1 and Figure 7 The second insulation structure 1142 may include a separable first insulation part 11421 and a second insulation part 11422, the second insulation part 11422 being exposed at the first mounting port 111b, and the shut-off valve 12 being located on the side of the second insulation part 11422 away from the first mounting port 111b.

[0074] When the shut-off valve 12 malfunctions and requires repair, the second insulation part 11422 can be removed from the first mounting port 111b, exposing the shut-off valve 12 to the first mounting port 111b for repair. For example, when the coil of the shut-off valve 12 malfunctions and needs to be replaced, the connection between the wire and the coil can be disconnected first, then a new coil can be replaced. After connecting the wire to the new coil, the second insulation part 11422 can be installed into the first receiving cavity 111a. The entire process does not require removing the entire foam component, nor does it require disassembling or moving the electrical control box 20. This improves the repair efficiency of the staff and facilitates after-sales maintenance.

[0075] For example, please refer to Figure 10 The second insulation part 11422 may have a gripping structure 114221 on the side near the first mounting port 111b.

[0076] The grip structure 114221 is for workers to grip in order to remove the second insulation part 11422 from the first mounting port 111b.

[0077] Please continue reading. Figure 10 The second insulation part 11422 has two recessed notches (not shown) on the side near the first mounting port 111b, and a gripping structure 114221 is formed between the sidewalls of the two notches. That is, the operator can grasp the gripping structure 114221 by reaching into the two notches. In other embodiments, the gripping structure 114221 may also be a protruding structure.

[0078] For example, please refer to Figure 1 , Figures 4 to 9 The valve box body 111 includes a base plate 1111 and a first side plate 1112 disposed on one side of the base plate 1111. The mounting bracket 113 is disposed on the first side plate 1112. The valve box body 111 also includes a second side plate 1113, a third side plate 1114 and a fourth side plate 1115. The base plate 1111, the first side plate 1112, the second side plate 1113, the third side plate 1114 and the fourth side plate 1115 together enclose a first receiving cavity 111a. The first mounting opening 111b is located on the side of the first receiving cavity 111a opposite to the base plate 1111. The first side plate 1112, which is equipped with the mounting bracket 113, is welded to the base plate 1111. During assembly, the first insulation structure 1141 is first placed on the base plate 1111, and then the connecting pipe 13 and the shut-off valve 12 are installed on the first insulation structure 1141. The connecting pipe 13 is fixed and limited by pipe clamps. Then, the first insulation part 11421 and the second insulation part 11422 are stacked on the first insulation structure 1141 in sequence to jointly wrap the connecting pipe 13 and the shut-off valve 12. After the insulation component 114 is installed, the second side plate 1113 is installed on the base plate. On the side opposite to the first side plate 1112 (installing the second side plate 1113 later can avoid interference between the insulation component 114 and the mounting bracket 113), place the electrical control box body 211 with the electrical control board 22 in the first receiving cavity 111a, so that the electrical control box body 211 and the mounting bracket 113 are fixed. Then, install the third side plate 1114 and the fourth side plate 1115 on opposite sides of the base plate 1111 along the extension direction of the connecting pipe 13. After the wire connection is completed, the valve box cover 112 can be placed on the first mounting port 111b to complete the overall assembly.

[0079] Please see Figures 1 to 3 The refrigerant shut-off valve box 10 may also include a pressure relief valve 14 disposed on the connecting pipe 13. The pressure relief valve 14 is located outside the first receiving cavity 111a. The valve box body 11 also includes a protective cover 115, which covers the pressure relief valve 14 to protect the pressure relief valve 14.

[0080] In some embodiments, please refer to Figure 4 The insulation component 114 encloses the shut-off valve 12. The insulation component 114 may have a first wire passage 114a and a first wire passage channel 114b that communicates with the first wire passage 114a and is located inside the insulation component 114. That is, the first wire passage channel 114b extends inside the insulation component 114 and communicates with the outside of the insulation component 114 through the first wire passage 114a, so that the wire electrically connected to the shut-off valve 12 can extend out of the insulation component 114 from the first wire passage channel 114b and the first wire passage 114a.

[0081] The control box 21 has a second wiring port (not shown) that connects to the second receiving cavity 211a. Both the first wiring port 114a and the second wiring port are connected to the external environment outside the refrigerant shut-off valve box 10, so that the wiring path for connecting the shut-off valve 12 and the control board 22 passes outside the refrigerant shut-off valve box 10. In other words, a section of the wire connecting the control board 22 and the shut-off valve 12 is located outside the refrigerant shut-off valve box 10, which facilitates the wiring and cable management for operators.

[0082] In other embodiments, the first and second ports may not be connected to the external environment, but to the first receiving cavity 111a. That is, the wires connecting the control board 22 and the shut-off valve 12 do not pass outside the shut-off valve 12 box, but only through the first receiving cavity 111a.

[0083] Preferably, please refer to Figure 1 , Figure 3 and Figure 9 The first wiring port 114a and the second wiring port can face the same side of the refrigerant cut-off control component to reduce wiring distance.

[0084] For example, please refer to Figure 3 and Figure 9 The refrigerant shut-off control assembly may also include a first wire-passing rubber ring 30 having a second wire-passing channel (not shown in the figure), and the refrigerant shut-off valve box 10 having a third wire-passing port (not shown in the figure). The first wire-passing rubber ring 30 is sealed through the second wire-passing port and the third wire-passing port. The second wire-passing channel is in communication with the second receiving cavity 211a and the external environment, respectively.

[0085] The first wire guide ring 30 can simultaneously waterproof and seal the second and third wire guide openings, and also clamp and fix the wires to prevent them from loosening.

[0086] More preferably, the second thread guide ring 40 may include a waterproof structure located within the second thread guide channel to prevent external rainwater and moisture from entering the second receiving cavity 211a through the second thread guide channel. In other embodiments, a cable tie can be used to secure the first thread guide ring 30, causing the first thread guide ring 30 to elastically deform and reduce the cross-sectional area of ​​the second thread guide channel, thereby preventing external rainwater and moisture from entering the second receiving cavity 211a.

[0087] In some embodiments, please refer to Figure 9 and Figure 13 The electrical control box 21 may have a fourth wiring port 211c communicating with the second receiving cavity 211a. The refrigerant shut-off valve box 10 has a fifth wiring port (not shown). The refrigerant shut-off control assembly also includes a second wiring ring 40, which includes a sealing ring 41 with a wiring through hole and a baffle 42 that blocks the wiring through hole. The baffle 42 can be reversibly opened under external force. The sealing ring 41 is sealed at the fifth wiring port, and the wiring through hole communicates with the fourth wiring port 211c at least after the baffle 42 is opened.

[0088] The fourth cable port 211c and the fifth cable port are used for other wires to pass through. Other wires refer to wires that are connected to the control board 22, other than the shut-off valve 12, including but not limited to power lines.

[0089] The second thread guide ring 40 is used to seal the fifth thread guide opening to prevent external rainwater and moisture from entering the first receiving cavity 111a.

[0090] When there is a need for multiple wires to pass through, a fourth wire pass 211c and a fifth wire pass can be set up to correspond one-to-one with multiple wires, so as to avoid multiple wires being passed through a first wire pass rubber ring 30 at the same time, which would reduce the waterproof effect of the first wire pass rubber ring 30.

[0091] In some embodiments, please refer to Figure 1 , Figures 9 to 12 The electrical control box 21 includes an electrical control box body 211 having a second receiving cavity 211a and a second mounting port 211b communicating with the second receiving cavity 211a. The electrical control box body 211 may include an end plate 2111 and a side panel 2112 disposed on one side of the end plate 2111 to jointly enclose the receiving cavity with the end plate 2111. The side panel 2112 includes a first plate 21121, two second plates 21122, and a third plate 21123. The first plate 21121 and the third plate 21123 are disposed opposite to each other, and the two second plates 21122 are disposed opposite to each other. When the refrigerant cut-off control assembly is in the installed state, the first plate 21121 is located on the top side of the third plate 21123 along the height direction.

[0092] In other words, when the refrigerant cut-off control component is in the installed state, the second mounting port 211b faces the side of the refrigerant cut-off control component, rather than the top or bottom side in the height direction, which facilitates after-sales maintenance.

[0093] Figure 10 The second mounting port 211b faces the first mounting port 111b, which means that the first mounting port 111b also faces the side of the refrigerant cut-off control component, in order to further facilitate the staff to wire or repair the electrical control board 22.

[0094] Please see Figure 1 and Figure 13 The electrical control box 21 also includes an electrical control box cover 212 that covers the second mounting port 211b to seal the second receiving cavity 211a. In some embodiments, the electrical control box 21 may only include the electrical control box body 211 without the electrical control box cover 212, and the valve box cover 112 may be simultaneously covered by the first mounting port 111b and the second mounting port 211b to simultaneously seal the first receiving cavity 111a and the second receiving cavity 211a.

[0095] For example, please refer to Figure 10 and Figure 11 The first plate 21121 may have a first flange 211211 formed by folding on the side close to each of the second plates 21122, and the first flange 211211 covers the outer surface of the second plate 21122 on the same side.

[0096] In other words, when the refrigerant cut-off control component is in the installed state, the first flange 211211 is folded to the bottom side in the height direction. Since the first flange 211211 covers the outer surface of the second plate 21122, when condensation or rainwater appears on the outer surface of the first plate 21121, the condensation or rainwater can only flow downward along the first flange 211211 under the action of gravity, and cannot enter the second receiving cavity 211a from the gap between the first flange 211211 and the second plate 21122. This can effectively prevent condensation or rainwater from entering the electrical control box 20.

[0097] For example, please refer to Figure 10 and Figure 12 Each second plate 21122 may have a second flange 211221 formed by folding on the side near the third plate 21123, and the second flange 211221 covers the outer surface of the third plate 21123.

[0098] In other words, when the refrigerant cut-off control component is in the installed state, the two second flanges 211221 fold towards each other. Since the second flanges 211221 cover the outer surface of the third plate 21123, when liquids such as condensate or rainwater appear on the outside of the second plate 21122, the condensate or rainwater can only flow along the outer surface of the second flanges 211221 and cannot enter the second receiving cavity 211a through the gap between the second flanges 211221 and the third plate 21123. This can effectively prevent condensate or rainwater from entering the electrical control box 20.
