Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to an air conditioner. Background Technology

[0002] Air conditioners are common household appliances in people's daily lives. An air conditioner typically consists of an indoor unit and an outdoor unit. The indoor unit is installed indoors, while the outdoor unit is installed outdoors.

[0003] To control the air conditioner, it has an electronic control component. This component can become short-circuited or corroded due to condensation. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an air conditioner and an air conditioner that aims to at least partially solve the technical problem that condensation in the electronic control components may cause short circuits and corrosion of the electronic control board.

[0005] The technical solution of this invention is as follows:

[0006] An air conditioner, characterized in that it includes: a heat exchange assembly; an electrical control box detachably connected to the heat exchange assembly; a sealing element disposed within and connected to the electrical control box; an electrical control board connected to the sealing element and disposed within the electrical control box; and a heat insulation assembly disposed between the electrical control board and the heat exchange assembly.

[0007] Because the control box is detachably connected to the heat exchange assembly, it is supported by the heat exchange assembly. Since the seal is located inside and connected to the control box, it is supported by the control box. The control board is connected to the seal and located inside the control box, thus supporting the control board. Simultaneously, the seal isolates the control board from the heat exchange assembly, preventing condensation and cold air from contacting the control board, thus avoiding condensation formation and ensuring its safety and reliability. Furthermore, the seal increases the distance between the control board and the heat exchange assembly, reducing the risk of condensation buildup. The insulation component reduces the possibility of temperature interference on the control board from the heat exchange components, thereby reducing the likelihood of condensation on the control board due to heat exchange between the control board and the heat exchange components. Since the insulation component is located between the control board and the heat exchange components, it can effectively insulate the control board, further avoiding or reducing heat exchange between the control board and the heat exchange components. This allows the temperatures of different surfaces of the control board to be closer, eliminating the temperature difference between the different surfaces of the control board. This prevents condensation caused by temperature differences between the different surfaces of the control board, thus preventing control board failure and effectively improving the reliability of the control board.

[0008] In some implementations, the insulation component includes: a first insulation element disposed between the electrical control board and the electrical control box; and a second insulation element disposed between the electrical control box and the heat exchange component, so as to achieve thermal insulation.

[0064] This application is described below with reference to the accompanying drawings and specific embodiments:

[0065] The air conditioner and air conditioner provided in this embodiment are intended to solve, to at least some extent, the technical problem that the control board may be short-circuited or corroded due to condensation.

[0066] Figure 1 These are schematic diagrams of the structure of an air conditioner according to some embodiments; Figure 2 for Figure 1 Exploded view of a central air conditioner; Figure 3 for Figure 1 A schematic diagram showing the interaction between the central air conditioner and the electrical control box; Figure 4 for Figure 3 An exploded view of the central electrical control box from a first-person perspective; Figure 5 for Figure 3 An exploded view of the central control box from a second-person perspective. (Combined with...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The air conditioner according to this application embodiment includes: a heat exchange assembly 10, an electrical control box 20, a sealing member 30, an electrical control board 40, and a heat insulation assembly 50. The electrical control box 20 is detachably connected to the heat exchange assembly 10. The sealing member 30 is disposed inside and connected to the electrical control box 20. The electrical control board 40 is connected to the sealing member 30 and disposed inside the electrical control box 20. The heat insulation assembly 50 is disposed between the electrical control board 40 and the heat exchange assembly 10.

[0067] Air conditioners can be ducted, window, wall-mounted, or floor-standing units.

[0068] Since the control box 20 is detachably connected to the heat exchange assembly 10, the heat exchange assembly 10 supports the control box 20. Since the seal 30 is located inside and connected to the control box 20, the control box 20 supports the seal 30. The control board 40 is connected to the seal 30 and located inside the control box 20, so the seal 30 supports the control board 40. Simultaneously, the seal 30 isolates the control board 40 from the heat exchange assembly 10, thus sealing the control board 40 to prevent condensate from contacting it and to prevent cold air from contacting it, preventing condensate buildup on the control board 40, ensuring its safety, and improving its reliability. Furthermore, the seal 30 increases the pressure between the control board 40 and the heat exchange assembly 10. The spacing between the two components reduces the possibility of temperature interference on the control board 40 from the heat exchange component 10, thereby reducing the possibility of condensation on the control board 40 due to heat exchange between the control board 40 and the heat exchange component 10. Since the insulation component 50 is located between the control board 40 and the heat exchange component 10, it can effectively insulate the control board 40, further avoiding or reducing heat exchange between the control board 40 and the heat exchange component 10. This allows the temperatures of different surfaces of the control board 40 to be closer, thus eliminating the temperature difference between the different surfaces of the control board 40. This prevents the generation of condensation on the control board 40 due to temperature differences between different surfaces, thereby preventing the control board 40 from failing and effectively improving its reliability.

[0069] In some embodiments, the insulation component 50 can act as a seal between the control board 40 and the heat exchange component 10 to prevent condensate from contacting the control board 40 and to prevent cold air from contacting the control board 40, thereby preventing condensate from forming on the control board 40, further ensuring the safety of the control board 40 and improving its reliability.

[0070] Figure 6 for Figure 3 Installation diagram of the central electrical control box; Figure 7 for Figure 3 A schematic diagram of the installation of the second insulation component of a central air conditioner; Figure 8 for Figure 3 Schematic diagram of the connection between the central sealing component and the electronic control board; Figure 9 for Figure 8 Side view. Combined with Figure 6 , Figure 7 , Figure 8 and Figure 9 In some embodiments, to achieve thermal insulation, the insulation component 50 includes a first insulation element 501 and a second insulation element 502. The first insulation element 501 is disposed between the electronic control board 40 and the electronic control box 20. The second insulation element 502 is disposed between the electronic control box 20 and the heat exchange component 10.

[0071] In some embodiments, the first insulation member 501 is disposed between the control board 40 and the control box 20, which can effectively insulate the control board 40, thereby further avoiding or reducing heat exchange between the control board 40 and the heat exchange component 10. This allows the temperatures of different surfaces of the control board 40 to be closer, thus eliminating the temperature difference between the different surfaces of the control board 40. This prevents the generation of condensation on the control board 40 due to temperature differences between different surfaces, thereby preventing the control board 40 from failing and effectively improving its reliability. At the same time, the first insulation member 501 can also act as a seal between the control board 40 and the control box 20 to prevent condensation from contacting the control board 40 and to prevent cold air from contacting the control board 40, thus preventing condensation from forming on the control board 40 and further ensuring the safety and improving the reliability of the control board 40.

[0072] In some embodiments, the second insulation element 502 is disposed between the control box 20 and the heat exchange assembly 10, which can effectively insulate the control board 40, thereby further avoiding or reducing heat exchange between the control board 40 and the heat exchange assembly 10. This allows the temperatures of different surfaces of the control board 40 to be closer, thus eliminating the temperature difference between the different surfaces of the control board 40. This prevents the generation of condensation on the control board 40 due to temperature differences between different surfaces, thereby preventing the control board 40 from failing and effectively improving the reliability of the control board 40. At the same time, the second insulation element 502 can also act as a seal between the control box 20 and the heat exchange assembly 10 to prevent condensation from contacting the control board 40 and to prevent cold air from contacting the control board 40, thus preventing the generation of condensation on the control board 40 and further ensuring the safety and improving the reliability of the control board 40.

[0073] In some embodiments, to enable the first insulation component 501 and the second insulation component 502 to have a heat insulation effect, heat insulation materials such as foam or sponge can be used to achieve the heat insulation effect; heat insulation coatings can also be used to achieve the heat insulation effect; or an insulation box with an internal heat insulation vacuum cavity can be used to achieve the heat insulation effect; and so on. However, to reduce costs and facilitate manufacturing while achieving the heat insulation effect, the first insulation component 501 and the second insulation component 502 can be made of sponge.

[0074] Combination Figure 4 and Figure 5In some embodiments, to support and seal the electronic control board 40, the electronic control board 40 includes an electronic control mounting component 401, a plate 402 disposed on the electronic control mounting component 401, and a capacitor 403 disposed on the plate 402. The sealing component 30 includes a connecting portion 301 and a receiving portion 302. The connecting portion 301 is connected to the electronic control mounting component 401 and the electronic control box 20. The receiving portion 302 is connected to the connecting portion 301 and has a cavity for accommodating the capacitor 403.

[0075] In some embodiments, the connecting portion 301 is connected to the side of the control box 20 facing the heat exchange assembly 10, so as to support the connecting portion 301 through the control box 20. The electrical control mounting member 401 is connected to the end of the connecting portion 301 away from the heat exchange assembly 10, so as to support the electrical control mounting member 401 through the connecting portion 301, thereby ensuring the stability of the circuit board 40 installation. Since the capacitor 403 protrudes from the surface of the board body 402, in order to accommodate the capacitor 403, the capacitor 402 is disposed in the cavity of the receiving portion 302, and the cavity accommodates the capacitor 402 to facilitate the connection between the control board 40 and the sealing member 30. The receiving portion 302 protrudes from the surface of the connecting portion 301 in the direction of the heat exchange assembly 10.

[0076] In some embodiments, the connecting portion 301 and the receiving portion 302 are located between the circuit board 40 and the heat exchange assembly 10, so that the connecting portion 301 and the receiving portion 302 can isolate the electrical control mounting component 401, the plate body 402 and the capacitor 403 from the heat exchange assembly 10, thereby achieving a seal on the electrical control mounting component 401, the plate body 402 and the capacitor 403, to prevent condensate from contacting the plate body 402 and the capacitor 403, and also to prevent cold air from contacting the electrical control mounting component 401, the plate body 402 and the capacitor 403, thus preventing condensate from forming on the electrical control mounting component 401, the plate body 402 and the capacitor 403, ensuring the safety of the electrical control board 40 and improving the reliability of the electrical control board 40. Furthermore, the connecting portion 301 and the receiving portion 302 can increase the distance between the electrical control mounting component 401, the plate 402 and the capacitor 4033 and the heat exchange assembly 10, reducing the possibility that the electrical control mounting component 401, the plate 402 and the capacitor 403 will be affected by the temperature of the heat exchange assembly 10. This reduces the possibility that heat exchange will occur between the electrical control mounting component 401, the plate 402 and the capacitor 403 and the heat exchange assembly 10, resulting in condensation on the electrical control mounting component 401, the plate 402 and the capacitor 403, thus ensuring the safety of the electrical control board 40.

[0077] In some embodiments, to achieve thermal insulation, a first insulation member 501 is located between the connecting portion 301 and the receiving portion 302 and the electrical control box 20. The first insulation member 501 separates the connecting portion 301 and the receiving portion 302 from the electrical control box 20, avoiding or reducing heat exchange between the heat exchange assembly 10 and the connecting portion 301 and the receiving portion 302. Consequently, it avoids or reduces heat exchange between the electrical control mounting component 401, the plate 402, and the capacitor 403 and the heat exchange assembly 10. This effectively insulates the electrical control mounting component 401, the plate 402, and the capacitor 403, thereby bringing the temperatures of different surfaces of the electrical control board 40 closer together. This eliminates the temperature difference between the different surfaces of the electrical control mounting component 401, the plate 402, and the capacitor 403, thus preventing the electrical control board from experiencing temperature differences. The temperature difference between the different surfaces of the mounting component 401, plate 402, and capacitor 403 causes condensation, which prevents the control board 40 from failing and effectively improves its reliability. Simultaneously, the first insulation component 501 acts as a seal between the connecting part 301 and the receiving part 302 and the control box 20, preventing condensation from contacting the mounting component 401, plate 402, and capacitor 403, and also preventing cold air from contacting them. This further ensures the safety of the mounting component 401, plate 402, and capacitor 403 and improves their reliability.

[0078] Of course, in some other embodiments, the first insulation member 501 can be located between the connecting part 301 and the electrical control mounting part 401 and between the receiving part 302 and the capacitor 403, which can also achieve thermal insulation.

[0079] Since the receiving portion 302 protrudes from the surface of the connecting portion 301 facing the heat exchange assembly 10, in some embodiments, to facilitate the installation of the first insulation member 501, two first insulation members 501 are used. One of the two first insulation members 501 is located between the receiving portion 302 and the electrical control box 20, and is connected to one of the receiving portion 302 and the electrical control box 20 to achieve heat insulation. The other of the two first insulation members 501 is located between the connecting portion 301 and the electrical control box 20, and is connected to one of the connecting portion 301 and the electrical control box 20 to achieve heat insulation.

[0080] In some embodiments, one of the two first insulation members 501 may be connected to the receiving portion 302. Of course, in other embodiments, one of the two first insulation members 501 may be connected to the electrical control box 20.

[0081] In some embodiments, the other of the two first insulation members 501 may be connected to the connecting portion 301. Of course, in other embodiments, the other of the two first insulation members 501 may be connected to the electrical control box 20.

[0082] Combination Figure 4 and Figure 5 In some embodiments, to ensure the normal operation of the control board 40, the air conditioner further includes a heat sink 60. The heat sink 60 is connected to the sealing member 30 and the control board 40, and passes through the sealing member 30, the first insulation member 501, the control box 20, and the second insulation member 502 within the heat exchange assembly 10. The heat sink 60 transfers heat from the control board 40 to the heat exchange assembly 10 for heat exchange with the cold space within the heat exchange assembly 10, thereby reducing the temperature of the control board 40 and preventing it from burning out due to overheating, thus ensuring the reliability of the control board 40.

[0083] In some embodiments, since the heat sink 60 is connected to the seal 30 and the control board 40, the heat sink 60, the seal 30 and the control board 40 can form a whole to provide a seal, thereby preventing condensate and / or cold air in the heat exchange assembly 40 from entering the seal 30 through the gap between the heat sink 60 and the seal 30. This prevents condensate and / or cold air from contacting the control board 40, further ensuring the safety of the control board 40 and improving its reliability.

[0084] Combination Figure 4 and Figure 5 In some embodiments, to facilitate the installation of the electrical control box 20, the electrical control box 20 includes a box body 201 and a cover 202. The box body 201 is detachably connected to the heat exchange assembly 10 and is located outside the heat exchange assembly 10. The box body 201 is connected to the seal 30 and supports the seal 30. The cover 202 is connected to the box body 201 and is disposed inside the heat exchange assembly 10. A receiving portion 302 is disposed inside the cover 202 so that the cover 201 can accommodate the receiving portion 302, facilitating the installation of the receiving portion 302.

[0085] In some embodiments, the cover 201 has a receiving cavity, and the receiving part 302 can be disposed in the receiving cavity. One of the two first heat-insulating members 501 can be disposed on the inner wall of the receiving cavity to achieve heat insulation.

[0086] Combination Figure 3 , Figure 4 and Figure 5In some embodiments, to facilitate maintenance of the control board 40, the housing 201 includes a base box 2011 and a cover plate 2012. The base box 2011 is detachably connected to the heat exchange assembly 10 and to the seal 30 and the cover 202, supporting the seal 30 and the cover 202. The cover plate 2012 is detachably connected to the base box 2011. When maintenance of the control board 40 is required, the cover plate 2012 can be removed from the base box 2011 to expose the control board 40, facilitating maintenance and improving work efficiency. When the maintenance of the control board 40 is completed, the cover plate 2012 is connected to the base box 2011 to close the base box 2011, preventing external debris from colliding with the control board 40 and causing damage, thus ensuring the safety of the control board 40.

[0087] Combination Figure 3 In some embodiments, to facilitate the connection between the base box 2011 and the heat exchange component 10, one of the base box 2011 and the heat exchange component 10 has a first buckle 2013, and the other has a first slot 101. The first buckle 2013 can be snapped into the first slot 101. By snapping the first buckle 2013 into the first slot, pre-installation can be achieved. During the process of fastening the base box 2011 onto the heat exchange component 10, it is not necessary to support the base box 2011, which reduces labor intensity and improves installation efficiency.

[0088] In some embodiments, the base box 2011 may have a first latch 2013, and the heat exchange assembly 10 may have a first slot 101. Of course, in other embodiments, the heat exchange assembly 10 may have a first latch 2013, and the base box 2011 may have a first slot 101.

[0089] In some embodiments, when the first buckle 2013 is engaged in the first slot 101 to achieve pre-installation of the base box 2011 and the heat exchange component 10, there is a gap between the base box 2011 and the heat exchange component 10. In order to ensure sealing performance, the thickness of the second insulation member 502 is greater than the gap between the base box 2011 and the heat exchange component 10. When the base box 2011 is fastened to the heat exchange component 10, the base box 2011 will press the second insulation member 502, so that the second insulation member 502 is compressed, so that the second insulation member 502 can fully seal the electrical control box 20 and the heat exchange component 10, so as to prevent condensate from contacting the electrical control board 40 and cold air from contacting the electrical control board 40, and prevent condensate from forming on the electrical control board 40, thereby further ensuring the safety of the electrical control board 40 and improving the reliability of the electrical control board 40.

[0090] Combination Figure 4In some embodiments, to facilitate the connection between the base box 2011 and the cover plate 2012, one of the base box 2011 and the cover plate 2012 has a second buckle 2014, and the other has a second slot 2015. The second buckle 2014 can be snapped into the second slot 2015. By snapping the second buckle 2014 into the second slot 2015, pre-installation can be achieved. During the process of fastening the cover plate 2012 to the base box 2011, it is not necessary to support the cover plate 2012, which reduces labor intensity and improves installation efficiency.

[0091] In some embodiments, the bottom box 2011 may have a second latch 2014, and the cover plate 2012 may have a second slot 2015. Of course, in other embodiments, the cover plate 2012 may have a second latch 2014, and the bottom box 2011 may have a second slot 2015.

[0092] Combination Figure 4 In some embodiments, in order to ensure that the cover plate 2012 is installed in place on the bottom box 2011, one of the bottom box 2011 and the cover plate 2012 has a limiting member 2016, and the other has a limiting groove 2017. The limiting member 2016 can be locked in the limiting groove 2017. By the limiting member 2016 being locked in the limiting groove 2017, the cover plate 2012 is limited, ensuring that the installation position of the cover plate 2012 is accurate.

[0093] In some embodiments, the bottom box 2011 may have a limiting member 2016, and the cover plate 2012 may have a limiting groove 2017. Of course, in other embodiments, the cover plate 2012 may have a limiting member 2016, and the bottom box 2011 may have a limiting groove 2017.

[0094] In some embodiments, when the bottom box 2011 has a limiting member 2016, the limiting member 2016 may be located at the bottom of the bottom box 2011.

[0096] In some embodiments, when installing a ducted air conditioner, the heat exchange component 10, the fan component 701, and the return air housing 702 can be transported separately. Compared with the overall size and weight of the ducted air conditioner, the heat exchange component 10, the fan component 701, and the return air housing 702 are all reduced, making it easier to transport them to the installation location and avoiding transportation difficulties caused by confined spaces. When the heat exchange component 10, the fan component 701, and the return air housing 702 arrive at the installation location, the fan component 701 can be installed onto the heat exchange component 10, and then the return air housing 702 can be installed onto the heat exchange component 10 and covered over the fan component 701 to complete the installation of the ducted air conditioner. This facilitates the installation of the heat exchange component 10, the fan component 701, and the return air housing 702 and improves assembly efficiency.

[0099] In some embodiments, when the fan component 701 needs to be repaired or replaced, it is only necessary to remove the first top cover 7021 and / or the first chassis 7022 from the first main body 7023, without having to remove the entire return air box 702 from the heat exchange assembly 10. This enables maintenance of the machine in all scenarios, reduces labor intensity, eliminates the need to remove the air duct connected to the return air outlet, improves maintenance convenience, and increases work efficiency.

[0100] In some embodiments, the first top cover 7021 can be detachably connected to the first body 7023, and the first chassis 7022 can be fixedly connected to the first body 7023. Of course, in other embodiments, the first chassis 7022 can be detachably connected to the first body 7023, and the first top cover 7021 can be fixedly connected to the first body 7023. Even more specifically, both the first top cover 7021 and the first chassis 7022 can be detachably connected to the first body 7023.

[0101] In some embodiments, when the first chassis 7022 is fixedly connected to the first body 7023, the first chassis 7022 can be integrally formed with the first body 7023 to reduce costs and improve the stability of the connection between the first chassis 7022 and the first body 7023.

[0102] In some embodiments, when the first top cover 7021 is fixedly connected to the first body 7023, the first top cover 7021 can be integrally formed with the first body 7023 to reduce costs and improve the stability of the connection between the first top cover 7021 and the first body 7023.

[0103] In some embodiments, if the ducted air conditioner is suspended, the space above the ducted air conditioner is limited, but there is operating space at the bottom of the ducted air conditioner. In this case, the first chassis 7022 is detachably connected to the first main body 7023. The first chassis 7022 can be removed from the first main body 7023 to remove the fan component 701 for inspection and maintenance. This enables maintenance of the machine in all scenarios, reduces labor intensity, eliminates the need to remove the air duct connected to the return air vent, improves maintenance convenience, and increases work efficiency.

[0104] In some embodiments, if the ducted air conditioner is placed flat on the ceiling, the bottom of the ducted air conditioner cannot be disassembled, but there is operating space on the top of the ducted air conditioner. In this case, the first top cover 7021 is detachably connected to the first main body 7023. By removing the first top cover 7021 from the first main body 7023, the fan component 701 can be removed for inspection and maintenance. This enables maintenance of the machine in all scenarios, reduces labor intensity, eliminates the need to remove the air duct connected to the return air vent, improves maintenance convenience, and increases work efficiency.

The support member 7012 is detachably connected to the heat exchange assembly 10. The fan 7011 is detachably connected to the support member 7012.

[0107] In some embodiments, the fan 7011 is mounted on the support 7012. When the heat exchange assembly 10, the fan component 701, and the return air box 702 are ready for installation, the support 7012 can be mounted on the heat exchange assembly 10, and then the return air box 702 can be mounted on the heat exchange assembly 10 and covered on the fan component 701 to complete the installation of the ducted air conditioner. This facilitates the installation of the heat exchange assembly 10, the fan component 701, and the return air box 702, and improves assembly efficiency.

[0108] In some embodiments, when the fan 7011 needs to be inspected, the fan 7011 can be removed from the support 7012 without removing the support 7012. This enables maintenance of the machine in all scenarios, reduces labor intensity, and eliminates the need to remove the air duct connected to the return air outlet, thereby improving maintenance convenience and work efficiency.

It is not necessary to separate the entire heat exchange box 102 from the fan assembly 20, which enables maintenance of the machine in all scenarios, reduces labor intensity, and does not require the removal of the air duct connected to the air outlet, thus improving maintenance convenience and work efficiency.

[0114] In some embodiments, the second top cover 1021 can be detachably connected to the second body 1023, and the second chassis 1022 can be fixedly connected to the second body 1023.
