[0030] According to the air conditioner provided by one or more embodiments of the present disclosure, at least to some extent, the technical problem that the electric control assembly may be short-circuited and corroded due to condensation in the related art can be solved.

[0031] Fig. 1 is a structural schematic diagram of an air conditioner according to some embodiments of the present disclosure; Fig. 2 is an exploded view of the air conditioner in Fig. 1; Fig. 3 is an exploded view of a heat exchange assembly, an electric control board and an electric control box of the air conditioner in Fig. 1; Fig. 4 is an exploded view of the electric control box and the electric control board in Fig. 3 from a first perspective; Fig. 5 is an exploded view of the electric control box in Fig. 3 from a second perspective. In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the air conditioner according to the embodiments of the present disclosure comprises a heat exchange assembly 10, an electric control box 20, a sealing member 30, an electric control board 40 and a heat preservation assembly 50. The electric control box 20 is detachably connected with the heat exchange assembly 10. The sealing member 30 is arranged in the electric control box 20 and connected with the electric control box 20. The electric control board 40 is connected with the sealing member 30 and arranged in the electric control box 20. The heat preservation assembly 50 is arranged between the electric control board 40 and the heat exchange assembly 10.

[0032] In some embodiments, the air conditioner can be a ducted-type air conditioner, a window-type air conditioner, a wall-mounted air conditioner or a cabinet-type air conditioner.

[0033] Since the electric control box 20 is detachably connected with the heat exchange assembly 10, the electric control box 20 is supported by the heat exchange assembly 10. Since the sealing member 30 is arranged in the electric control box 20 and connected with the electric control box 20, the sealing member 30 is supported by the electric control box 20. The electric control board 40 is connected with the sealing member 30 and arranged in the electric control box 20, so the electric control board 40 is supported by the sealing member 30. Meanwhile, the sealing member 30 can isolate the electric control board 40 from the heat exchange assembly 10, so as to seal the electric control board 40, to avoid the contact between the condensed water and the electric control board 40, to avoid the contact between the cold air and the electric control board 40, to avoid the condensed water on the electric control board 40, to ensure the safety of the electric control board 40, and to improve the reliability of the electric control board 40. Moreover, the sealing member 30 can increase the distance between the electric control board 40 and the heat exchange assembly 10, to reduce the possibility that the electric control board 40 is interfered by the temperature of the heat exchange assembly 10, and to further reduce the possibility that the heat exchange between the electric control board 40 and the heat exchange assembly 10 causes the condensed water on the electric control board 40. Since the heat preservation assembly 50 is arranged between the electric control board 40 and the heat exchange assembly 10, the heat preservation assembly 50 can effectively isolate and heat preserve the electric control board 40, to further avoid or reduce the heat exchange between the electric control board 40 and the heat exchange assembly 10. Thus, the temperatures of different surfaces of the electric control board 40 can be close to each other, i.e. the temperature difference between different surfaces of the electric control board 40 is eliminated, so as to avoid the condensed water on the electric control board 40 caused by the temperature difference between different surfaces of the electric control board 40, to prevent the electric control board 40 from being invalid, and to effectively improve the reliability of the electric control board 40.

[0034] In some embodiments, the heat preservation assembly 50 can also play a sealing role between the electric control board 40 and the heat exchange assembly 10. The heat preservation assembly 50 can avoid the contact between the condensed water and the electric control board 40, to avoid the contact between the cold air and the electric control board 40, to avoid the condensed water on the electric control board 40, to further ensure the safety of the electric control board 40, and to improve the reliability of the electric control board 40.

[0035] Fig. 6 is a schematic view of the mounting structure of the electric control box in Fig. 3; Fig. 7 is an exploded view of the heat exchange assembly, the electric control board, the electric control box and the second heat preservation member of the air conditioner in Fig. 3; Fig. 8 is a schematic view of the connecting structure of the sealing member and the electric control board in Fig. 3; and Fig. 9 is a side view of the sealing member and the electric control board in Fig. 8. In combination with Figs. 6, 7, 8 and 9, in some embodiments, in order to realize heat isolation and heat preservation, the heat preservation assembly 50 comprises a first heat preservation member 501 and a second heat preservation member 502. The first heat preservation member 501 is arranged between the electric control board 40 and the electric control box 20. The second heat preservation member 502 is arranged between the electric control box 20 and the heat exchange assembly 10.

[0036] In some embodiments, the first heat insulation member 501 is arranged between the electric control board 40 and the electric control box 20, which can effectively insulate and heat the electric control board 40, so as to further avoid or reduce heat exchange between the electric control board 40 and the heat exchange assembly 10. Thus, the temperatures of different surfaces of the electric control board 40 can be close to each other, i.e., the temperature difference between different surfaces of the electric control board 40 is eliminated, so that the generation of condensed water on the electric control board 40 due to the temperature difference between different surfaces can be avoided, and thus the failure of the electric control board 40 can be prevented, and the reliability of the electric control board 40 can be effectively improved. Meanwhile, the first heat insulation member 501 can play a sealing role between the electric control board 40 and the electric control box 20, so as to avoid the contact between the condensed water and the electric control board 40, and avoid the contact between the cold air and the electric control board 40, and avoid the generation of condensed water on the electric control board 40, so as to further ensure the safety of the electric control board 40 and improve the reliability of the electric control board 40.

[0037] In some embodiments, the second heat insulation member 502 is arranged between the electric control box 20 and the heat exchange assembly 10, which can effectively insulate and heat the electric control board 40, so as to further avoid or reduce heat exchange between the electric control board 40 and the heat exchange assembly 10. Thus, the temperatures of different surfaces of the electric control board 40 can be close to each other, i.e., the temperature difference between different surfaces of the electric control board 40 is eliminated, so that the generation of condensed water on the electric control board 40 due to the temperature difference between different surfaces can be avoided, and thus the failure of the electric control board 40 can be prevented, and the reliability of the electric control board 40 can be effectively improved. Meanwhile, the second heat insulation member 502 can play a sealing role between the electric control box 20 and the heat exchange assembly 10, so as to avoid the contact between the condensed water and the electric control board 40, and avoid the contact between the cold air and the electric control board 40, and avoid the generation of condensed water on the electric control board 40, so as to further ensure the safety of the electric control board 40 and improve the reliability of the electric control board 40.

[0038] In some embodiments, in order to make the first heat insulation member 501 and the second heat insulation member 502 have the heat insulation effect, the first heat insulation member 501 and the second heat insulation member 502 can use heat insulation materials such as foams, sponges, etc., to achieve the heat insulation effect; the first heat insulation member 501 and the second heat insulation member 502 can be heat insulation coating to achieve the heat insulation effect; the first heat insulation member 501 and the second heat insulation member 502 can be heat insulation boxes with heat insulation vacuum cavities inside to achieve the heat insulation effect; etc. In order to reduce the cost and facilitate the production, in some embodiments, the first heat insulation member 501 and the second heat insulation member 502 can be sponges.

[0039] In combination with FIG. 4 and FIG. 5, in some embodiments, in order to realize the support and sealing of the electric control board 40, the electric control board 40 comprises an electric control mounting 401, a first board body 402 arranged on the electric control mounting 401, and a capacitor 403 arranged on the first board body 402. The sealing member 30 comprises a connecting portion 301 and a containing portion 302. The connecting portion 301 is connected with the electric control mounting 401 and the electric control box 20. The containing portion 302 is connected with the connecting portion 301 and is provided with a cavity for containing the capacitor 403.

[0040] In some embodiments, the connecting portion 301 is connected with the electric control box 20 towards the side of the heat exchange assembly 10, so as to support the connecting portion 301 by the electric control box 20. The electric control mounting 401 is connected with the end of the connecting portion 301 away from the heat exchange assembly 10, so as to support the electric control mounting 401 by the connecting portion 301, to ensure the stability of the installation of the electric control board 40. Since the capacitor 403 protrudes from the surface of the first board body 402, in order to contain the capacitor 403, the capacitor 402 is arranged in the cavity of the containing portion 302. The capacitor 402 is contained by the cavity, so as to facilitate the connection of the electric control board 40 and the sealing member 30. The containing portion 302 protrudes from the surface of the connecting portion 301 towards the heat exchange assembly 10.

[0041] In some embodiments, the connecting portion 301 and the containing portion 302 are located between the electric control board 40 and the heat exchange assembly 10, so that the connecting portion 301 and the containing portion 302 can isolate the electric control mounting 401, the first board body 402 and the capacitor 403 from the heat exchange assembly 10, to realize the sealing of the electric control mounting 401, the first board body 402 and the capacitor 403, to avoid the contact of the condensate water with the first board body 402 and the capacitor 403, and the contact of the cold air with the electric control mounting 401, the first board body 402 and the capacitor 403, to avoid the generation of condensate water on the electric control mounting 401, the first board body 402 and the capacitor 403, to ensure the safety of the electric control board 40 and improve the reliability of the electric control board 40. Moreover, the connecting portion 301 and the containing portion 302 can increase the distance between the electric control mounting 401, the first board body 402 and the capacitor 403 and the heat exchange assembly 10, to reduce the possibility that the electric control mounting 401, the first board body 402 and the capacitor 403 are disturbed by the temperature at the heat exchange assembly 10. In turn, the possibility that the heat exchange occurs between the electric control mounting 401, the first board body 402 and the capacitor 403 and the heat exchange assembly 10, to cause the generation of condensate water on the electric control mounting 401, the first board body 402 and the capacitor 403, is reduced, to ensure the safety of the electric control board 40.

[0042] In some embodiments, in order to achieve temperature insulation and heat preservation, the first heat preservation member 501 is located between the connecting portion 301 and the accommodating portion 302 and the electric control box 20. The connecting portion 301 and the accommodating portion 302 are separated from the electric control box 20 by the first heat preservation member 501, so as to avoid or reduce heat exchange between the heat exchange assembly 10 and the connecting portion 301 and the accommodating portion 302. In turn, heat exchange between the electric control mounting member 401, the first plate body 402 and the capacitor 403 and the heat exchange assembly 10 is avoided or reduced, so as to effectively insulate and preserve heat of the electric control mounting member 401, the first plate body 402 and the capacitor 403, so that the temperatures of different surfaces of the electric control board 40 are close, that is, the temperature difference between different surfaces of the electric control mounting member 401, the first plate body 402 and the capacitor 403 is eliminated. Thus, the generation of condensate water on the electric control mounting member 401, the first plate body 402 and the capacitor 403 due to the temperature difference between different surfaces can be avoided, so as to prevent the electric control board 40 from failing, thereby effectively improving the reliability of the electric control board 40. At the same time, the first heat preservation member 501 can play a sealing role between the connecting portion 301 and the accommodating portion 302 and the electric control box 20, so as to avoid contact of the condensate water with the electric control mounting member 401, the first plate body 402 and the capacitor 403, and also avoid contact of cold air with the electric control mounting member 401, the first plate body 402 and the capacitor 403, so as to avoid the generation of condensate water on the electric control mounting member 401, the first plate body 402 and the capacitor 403, further ensuring the safety of the electric control mounting member 401, the first plate body 402 and the capacitor 403, and improving the reliability of the electric control mounting member 401, the first plate body 402 and the capacitor 403.

[0043] Of course, in other embodiments, the first heat preservation member 501 can be located between the connecting portion 301 and the electric control mounting member 401, and / or between the accommodating portion 302 and the capacitor 403, so as to also achieve temperature insulation and heat preservation.

[0044] Since the accommodating portion 302 protrudes from the surface of the connecting portion 301 towards the heat exchange assembly 10, in some embodiments, in order to facilitate installation of the first heat preservation member 501, the number of the first heat preservation member 501 is two. One of the two first heat preservation members 501 is located between the accommodating portion 302 and the electric control box 20 and connected with one of the accommodating portion 302 and the electric control box 20, so as to achieve heat insulation and heat preservation. The other of the two first heat preservation members 501 is located between the connecting portion 301 and the electric control box 20 and connected with one of the connecting portion 301 and the electric control box 20, so as to achieve heat insulation and heat preservation.

[0045] In some embodiments, one of the two first heat preservation members 501 can be connected with the accommodating portion 302. Of course, in other embodiments, one of the two first heat preservation members 501 can be connected with the electric control box 20.

[0046] In some embodiments, the other of the two first heat preservation members 501 can be connected with the connecting portion 301. Of course, in other embodiments, the other of the two first heat preservation members 501 can be connected with the electric control box 20.

[0047] Please refer to FIG. 3 and FIG. 4, in some embodiments, the electric control board 40 comprises an electric control mounting member 401, a first board body 402 arranged on the electric control mounting member 401, a capacitor 403 arranged on the first board body 402, and a second board body 404 arranged on the electric control mounting member 401. The first board body 402 and the second board body 404 are electrically connected. One of the first board body 402 and the second board body 404 is a main control board, which can realize data communication between the air conditioner and external devices, such as a remote controller matched with the air conditioner, to realize opening, closing, working mode switching, temperature adjustment, air volume adjustment, etc. of the air conditioner. The other of the first board body 402 and the second board body 404 is a driving board, which can realize control of main working components in the air conditioner, such as a fan, a compressor, etc.

[0048] Please refer to FIG. 3 and FIG. 4, in some embodiments, the first board body 402 and the second board body 404 are respectively arranged on two opposite sides of the electric control mounting member 401. The electric control mounting member 401 can be a mounting bracket, two opposite sides of the mounting bracket are respectively provided with a mounting area, and the first board body 402 and the second board body 404 are respectively arranged in the mounting areas of the two opposite sides and connected with the electric control mounting member 401. The first board body 402 and the second board body 404 can be connected with the electric control mounting member 401 by screw locking, buckle connection, gluing, etc. The first board body 402 and the second board body 404 can be electrically connected by wires, and the wires are located outside the electric control mounting member 401. In some embodiments, a through hole can be arranged on the electric control mounting member 401, and at least one of the first board body 402 and the second board body 404 is provided with a conductive member, which passes through the through hole to realize electrical conduction between the first board body 402 and the second board body 404.

[0049] Please refer to FIG. 3 and FIG. 4, in some embodiments, the first board body 402 is a driving board, and the second board body 404 is a main control board. The first board body 402 has a larger heat generation than the second board body 404. In some embodiments, the first board body 402 is closer to the heat exchange assembly 10 than the second board body 404. By arranging the first board body 402 with larger heat generation close to the heat exchange assembly 10, the heat exchange assembly 10 can be used to cool the first board body 402.

[0050] In combination with FIG. 4 and FIG. 5, in some embodiments, in order to ensure that the electric control board 40 can work normally, the air conditioner further comprises a heat dissipation piece 60. The heat dissipation piece 60 is connected with the sealing piece 30 and the electric control board 40, and is arranged in the sealing piece 30, the first heat preservation piece 501, the electric control box 20 and the second heat preservation piece 502 in the heat exchange assembly 10. That is, the heat dissipation piece 60 passes through the sealing piece 30, the first heat preservation piece 501, the electric control box 20 and the second heat preservation piece 502, and extends into the heat exchange assembly 10. The heat on the electric control board 40 can be transmitted to the heat exchange assembly 10 through the heat dissipation piece 60, so as to exchange heat with the cold space in the heat exchange assembly 10, thereby reducing the temperature of the electric control board 40, avoiding that the electric control board 40 is burned due to the excessively high temperature, and ensuring the reliability of the electric control board 40.

[0051] In some embodiments, since the heat dissipation piece 60 is connected with the sealing piece 30 and the electric control board 40, the heat dissipation piece 60, the sealing piece 30 and the electric control board 40 can form an integral whole to play a sealing role, so as to avoid that the condensed water and / or the cold air in the heat exchange assembly 10 enters the sealing piece 30 through the gap between the heat dissipation piece 60 and the sealing piece 30. Thus, the condensed water and / or the cold air is avoided from contacting the electric control board 40, further ensuring the safety of the electric control board 40, and improving the reliability of the electric control board 40.

[0052] In combination with FIG. 4 and FIG. 5, in some embodiments, the heat dissipation piece 60 is connected with the first plate body 402. The heat dissipation piece 60 can be arranged on the region with a large amount of heat on the first plate body 402. For example, the first plate body 402 is a driving plate for driving the power components such as motors and fans to work, and the driving plate is provided with IGBT (Insulated-Gate-Bipolar-Transistor, Insulated-Gate-Bipolar-Transistor). The IGBT generates a large amount of heat when working, and thus the heat dissipation piece 60 can be located opposite to the IGBT. The heat dissipation piece 60 and the IGBT can be coated with heat-conducting glue. The IGBT exchanges heat with the heat dissipation piece 60, and the heat dissipation piece 60 cools and cools the IGBT.

[0053] In combination with FIG. 4 and FIG. 5, in some embodiments, in order to facilitate the installation of the electric control box 20, the electric control box 20 comprises a box body 201 and a cover body 202. The box body 201 is detachably connected with the heat exchange assembly 10 and located outside the heat exchange assembly 10. The box body 201 is connected with the sealing piece 30 and supports the sealing piece 30. The cover body 202 is connected with the box body 201 and arranged in the heat exchange assembly 10. The accommodating portion 302 is arranged in the cover body 202, so as to accommodate the accommodating portion 302 of the sealing piece 30 through the cover body 202, thereby facilitating the installation of the accommodating portion 302.

[0054] In some embodiments, the cover 202 is provided with a receiving cavity, and the receiving part 302 can be arranged in the receiving cavity. One of the two first heat insulation parts 501 can be arranged on the inner wall of the receiving cavity to achieve heat insulation.

[0055] In combination with FIGS. 3, 4 and 5, in some embodiments, in order to facilitate the maintenance of the electric control board 40, the box body 201 comprises a bottom box 2011 and a cover plate 2012. The bottom box 2011 is detachably connected with the heat exchange assembly 10, and is connected with the sealing part 30 and the cover 202, and supports the sealing part 30 and the cover 202 through the bottom box 2011.
