[0035] Hereinafter, an air conditioner 1000 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0036] like Figures 1-6 As shown, the air conditioner 1000 according to the embodiment of the present invention includes: a ventilation and heat exchange component 200 and an electric control box 100, the ventilation and heat exchange component 200 includes a fan 201 and an electric auxiliary heat, the fan 201 is connected to a fan line 2021, and the electric auxiliary heat is connected to an electric auxiliary heat line 2022; the electric control box 100 is arranged at one end of the ventilation and heat exchange component 200 in the length direction, and includes a box body 1, a box cover 2 and a strong electric board 3, a first chamber 111 is formed in the box body 1, and the entrance of the first chamber 111 is along the longitudinal direction. It is open in the vertical direction, and the high-voltage board 3 is suitable for being loaded into the first chamber 111 through the entrance of the first chamber 111. The box cover 2 cooperates with the box body 1 and seals the entrance of the first chamber 111. A plurality of wire clamping openings 13 are formed on one side of the box body 1 close to the ventilation and heat exchange component 200. The wire clamping openings 13 are located at the end of the box body 1 close to the box cover 2 and are open toward the box cover 2. The fan line 2021 and the electric auxiliary heating line 2022 are respectively passed through the box body 1 through different wire clamping openings 13 to be connected to the high-voltage board 3 respectively.

[0037] As a result, the difficulty of wire jamming can be reduced, the risk of wire pressing can be eliminated, the stability of the electric control box 100 can be improved, and the reliability of the air conditioner 1000 can be improved.

[0038] First, if Figure 1-Figure 3 As shown, air conditioner 1000 includes a housing, ventilation and heat exchange components 200, and an electrical control box 100, both of which are mounted within the housing. Ventilation and heat exchange components 200 include a fan 201 and an electric auxiliary heater (i.e., a PTC). Fan 201 is used to blow conditioned air into the indoor space, and the electric auxiliary heater is used to heat the conditioned air. Fan 201 is connected to a fan cable 2021, which is electrically connected to the electrical control box 100. The electric auxiliary heater is connected to an electric auxiliary heater cable 2022, which is electrically connected to the electrical control box 100, so that the electrical control box 100 can power the fan 201 and the electric auxiliary heater, respectively.

[0039] The electric control box 100 can be arranged in the longitudinal direction of the ventilation and heat exchange component 200 (refer to Figure 1 The electric control box 100 includes a box body 1, a box cover 2 and a strong electric board 3. A first chamber 111 is formed in the box body 1. The entrance of the first chamber 111 is perpendicular to the length direction of the ventilation and heat exchange component 200 (reference direction). Figure 3 The second direction F2 shown, such as the front-to-back direction shown in the figure, is open, and the strong current board 3 is matched with the entrance of the first chamber 111 so that the strong current board 3 can be loaded into the first chamber 111 through the entrance of the first chamber 111. The box cover 2 cooperates with the box body 1 and is used to seal the entrance of the first chamber 111.

[0040] At the same time, the side of the box body 1 close to the ventilation and heat exchange component 200 (refer to Figure 1 The left side shown in the figure is provided with a plurality of wire clamping openings 13, and the plurality of wire clamping openings 13 are arranged at intervals. The wire clamping openings 13 are located at the end of the box body 1 close to the box cover 2 and are open toward the box cover 2. The fan line 2021 and the electric auxiliary heating line 2022 are respectively clamped in different wire clamping openings 13 from the open end to pass through the box body 1, so that the fan line 2021 and the electric auxiliary heating line 2022 can extend into the first chamber 111 to be connected to the high-voltage board 3, so that the electric control box 100 can supply power to the fan 201 and the electric auxiliary heating through the high-voltage board 3.

[0041] Through the above settings, the fan line 2021 and the electric auxiliary heating line 2022 can be more easily connected to the box body 1, reducing the difficulty of clamping the line, and reducing the risk of wire compression of the electric auxiliary heating line 2022 and the fan line 2021, thereby improving the reliability of the electric control box 100.

[0042] According to the air conditioner 1000 of the embodiment of the present invention, by setting the wire clamping opening 13 to be open toward the box cover 2, the fan line 2021 and the electric auxiliary heating line 2022 can be clamped into the wire clamping opening 13 from the open end when the box cover 2 is opened, thereby reducing the difficulty of clamping the wires. Moreover, by setting the fan line 2021 and the electric auxiliary heating line 2022 to be clamped in different wire clamping openings 13, the risk of wire compression can be eliminated, the stability of the electric control box 100 is improved, and thus the reliability of the air conditioner 1000 is improved.

[0043] In some embodiments of the present invention, the ventilation and heat exchange component 200 includes a heat exchanger 203, which is externally connected to a refrigerant pipeline 204. The refrigerant pipeline 204 is located on a side of the heat exchanger 203 near the electrical control box 100. The box body 1 includes a first box portion 11 and a stopper 14. The first box portion 11 defines a first chamber 111. The stopper 14 is located on a side of the first box portion 11 near the ventilation and heat exchange component 200 and forms a wire accommodating space 15 between the stopper 14 and the first box portion 11. The wire accommodating space 15 is used to accommodate a high-voltage power line 202 that passes through the wire clamping port 13. The stopper 14 blocks the wire accommodating space 15 and the refrigerant pipeline 204. It should be noted that the high-voltage power line 202 includes a fan line 2021 and an auxiliary heating line 2022.

[0044] For example, refer to Figure 2-Figure 4 As shown, the ventilation and heat exchange component 200 includes a heat exchanger 203, and the heat exchanger 203 is externally connected to a refrigerant pipeline 204. The refrigerant pipeline 204 is located on the side of the heat exchanger 203 close to the electrical control box 100. The heat exchanger 203 can exchange heat with the air-conditioning wind through the refrigerant pipeline 204, so that the air-conditioning wind can cool or heat the indoor space.

[0045] The box body 1 includes a first box portion 11 and a stopper 14. The first box portion 11 is adapted to define a first chamber 111. The stopper 14 is provided on a side of the first box portion 11 close to the ventilation and heat exchange component 200. At least a portion of the stopper 14 is spaced apart from the first box portion 11, so as to form a wire accommodating space 15 between the stopper 14 and the first box portion 11. The wire accommodating space 15 can be used to accommodate the power line 202 passing through the wire clamping port 13, and the stopper 14 can be blocked between the wire accommodating space 15 and the refrigerant pipeline 204. When condensed water forms on the outer peripheral wall of the refrigerant pipeline 204, the stopper 14 can prevent the condensed water from flowing toward the power line 202.

[0046] It can be understood that the wire accommodating space 15 can be used to accommodate the excess part of the strong wire 202 to eliminate the line length error of the strong wire 202, ensure the precise installation of the strong wire 202, and the stopper 14 can prevent condensed water from flowing along the strong wire 202 and causing danger, thereby improving the safety of the air conditioner 1000.

[0047] In some embodiments of the present invention, the electric auxiliary heat can be constructed in a rod shape and arranged between the fan 201 and the heat exchanger 203, and the length direction of the electric auxiliary heat is in line with the axial direction of the fan 201 (refer to Figure 1 Thus, the heating effect of the electric auxiliary heating can be ensured.

[0048] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the stopper 14 may include two elastic buckles 141, and the two elastic buckles 141 are arranged along the spacing direction of the plurality of clamping ports 13 (refer to Figure 3 The third direction F3 shown, such as the up and down direction shown in the figure, is spaced to form a wire passing opening 142 between the two elastic buckles 141, and the wire passing opening 142 is connected to the wire accommodating space 15, and the fan line 2021 and the electric auxiliary heating line 2022 are suitable for entering the wire accommodating space 15 through the wire passing opening 142.

[0049] Through the above-mentioned setting, the size of the wire passing opening 142 can be made smaller, which is conducive to improving the blocking effect of the stopper 14, and the fan line 2021 and the electric auxiliary heating line 2022 entering the wire accommodating space 15 can be kept parallel to the wire clamping opening 13, so that the fan line 2021 and the electric auxiliary heating line 2022 can be more easily clamped into the corresponding wire clamping opening 13, thereby reducing the assembly difficulty of the air conditioner 1000.

[0050] In some embodiments of the present invention, the elastic buckle 141 includes a guide section 1411 and a bending section 1412, the two ends of the guide section 1411 are respectively a fixed end 1411a and a free end 1411b, the free end 1411b of the guide section 1411 is inclined relative to the fixed end 1411a along the direction from the ventilation and heat exchange component 200 to the first box part 11, and extends toward the direction close to the other elastic buckle 141, and the bending section 1412 is bent from the free end 1411b of the guide section 1411 toward the direction away from the other elastic buckle 141.

[0051] For example, refer to Figure 3-Figure 5 As shown, an elastic buckle 141 can be provided including a guide section 1411 and a bending section 1412, wherein the two ends of the guide section 1411 along the length direction are a fixed end 1411a and a free end 1411b respectively, and the fixed end 1411a of the guide section 1411 is connected to the side of the first box part 11 close to the ventilation and heat exchange component 200.

[0052] In the direction from the ventilation and heat exchange component 200 to the first box portion 11, the free end 1411b of the guide section 1411 extends obliquely relative to the fixed end 1411a toward the other elastic buckle 141, thereby configuring the wire passage 142 into a trumpet shape. This makes it easier for the power line 202 to be inserted into the wire passage 142, thereby reducing the difficulty of installing the power line 202. Simultaneously, the bent section 1412 can be connected to the free end 1411b of the guide section 1411 and configured to bend from the free end 1411b of the guide section 1411 toward a direction away from the other elastic buckle 141, thereby configuring the elastic buckle 141 into a U-shaped structure. This enhances the elastic buckle 141's resistance to deformation and improves its structural stability. This improves the design rationality of the elastic buckle 141.

[0053] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the side wall of the first box part 11 close to the ventilation and heat exchange component 200 is the first box wall 112, and the wire clamping opening 13 passes through the first box wall 112 in the horizontal direction. There are two wire clamping openings 13 and they are respectively arranged at the upper and lower ends of the first box wall 112. The stopper 14 is arranged on the side of the first box wall 112 close to the ventilation and heat exchange component 200, and the wire passing opening 142 is located between the two wire clamping openings 13 in the upper and lower directions, that is, the wire passing opening 142 is higher than the wire clamping opening 13 at the lower end and lower than the wire clamping opening 13 at the upper end.

[0054] For example, the fan cable 2021 enters the cable space 15 through the cable opening 142 and extends toward the upper cable opening 13. If condensation forms on the fan cable 2021, the condensation can flow back along the fan cable 2021 toward the cable opening 142, making it difficult to enter the first box portion 11. The auxiliary electric heating cable 2022 enters the cable space 15 through the cable opening 142 and extends toward the lower cable opening 13. If condensation forms on the auxiliary electric heating cable 2022, the condensation can flow downward along the auxiliary electric heating cable 2022, making it difficult to enter the lower cable opening 13 horizontally and thus the first box portion 11.

[0055] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the box body 1 is made of sheet metal at the wire clamping opening 13. This can prevent fire and improve safety and reliability.

[0056] In some embodiments of the present invention, the opening size of the wire passage 142 can be set to be greater than or equal to 6.1 mm, the spacing between the elastic buckle 141 and the first box wall 112 can be set to be greater than or equal to 9.3 mm, and the minimum width of the wire space 15 can be set to be greater than or equal to 8.7 mm. This makes it easier to install the power line 202.

[0057] In some embodiments of the present invention, Figure 2-Figure 3 As shown, the box body 1 includes a first box portion 11, the first box portion 11 defines a first chamber 111, a side wall of the first box portion 11 close to the ventilation and heat exchange component 200 is set as a first box wall 112, and a side wall of the first box portion 11 away from the ventilation and heat exchange component 200 is set as a second box wall 113, and the wire clamping port 13 passes through the first box wall 112 along the thickness direction of the first box wall 112, wherein the thickness direction of the substrate 31 of the strong current board 3 is set to the spacing direction of the first box wall 112 and the second box wall 113 (reference Figure 3 The first direction F1 shown is consistent with the left and right directions shown in the figure.

[0058] Through the above-mentioned arrangement, the first box wall 112 and the second box wall 113 can be respectively opposite to the thickness sides of the substrate 31, so that the high-voltage wire 202 clamped in the wire clamping port 13 can be directly opposite to the thickness side of the substrate 31, so that the high-voltage wire 202 can be more easily connected to the high-voltage board 3, reducing the difficulty of processing and layout of the electric control box 100.

[0059] In some embodiments of the present invention, the distance W1 between the substrate 31 and the second box wall 113 is greater than the distance W2 between the substrate 31 and the first box wall 112, and the side of the high-voltage board 3 facing the second box wall 113 is provided with a wiring terminal connected to the high-voltage wire 202, and the wiring terminal includes a first wiring terminal connected to the fan line 2021, and the wiring terminal also includes a second wiring terminal connected to the electric auxiliary heating line 2022.

[0060] For example, refer to Figure 3 As shown, the distance between the substrate 31 and the second box wall 113 can be set to be greater than the distance between the substrate 31 and the first box wall 112, so that the substrate 31 can be placed close to the first box wall 112. A connection terminal is provided on the side of the strong current board 3 facing the second box wall 113, and the connection terminal is used to connect to the strong power line 202 so that the strong current board 3 can supply power to the outside through the strong power line 202.

[0061] Among them, the high-voltage power line 202 includes a fan line 2021 and an electric auxiliary heating line 2022, and the wiring terminals include a first wiring terminal and a second wiring terminal. The first wiring terminal and the second wiring terminal are spaced apart. The first wiring terminal is used to connect to the fan line 2021 so that the high-voltage board 3 can supply power to the fan 201, and the second wiring terminal is used to connect to the electric auxiliary heating line 2022 so that the high-voltage board 3 can supply power to the electric auxiliary heating.

[0062] It can be understood that by setting the base plate 31 close to the first box wall 112, the distance between the wire clamping port 13 and the wiring terminal can be shortened, which is beneficial to shortening the length of the high-voltage wire 202 and saving costs. By setting the wiring terminal on the side of the high-voltage board 3 facing the second box wall 113, a larger operating space can be left for the installation of the high-voltage wire 202, which is beneficial to reducing the installation difficulty of the high-voltage wire 202 and improving the design rationality of the air conditioner 1000.

[0063] In some embodiments of the present invention, referring to Figure 3-Figure 4 As shown, a wire hole 1131 is provided on the second box wall 113, and the wire hole 1131 is opened on the second box wall 113, and the wire hole 1131 is used to connect the inside and outside of the first box part 11, and the high-voltage electrical harness 5 including at least one wire body 51 of the power cord 511 and the indoor and outdoor unit connecting wire 512 is passed through the wire hole 1131 to be connected to the high-voltage board 3.

[0064] Exemplarily, a high-voltage electrical harness 5 can be provided including a power cord 511 and an indoor and outdoor unit connecting cord 512. Both the power cord 511 and the indoor and outdoor unit connecting cord 512 are passed through the wire hole 1131 and are electrically connected to the high-voltage board 3. An external power source can supply power to the high-voltage board 3 through the power cord 511, and the high-voltage board 3 can supply power to the air-conditioning outdoor unit through the indoor and outdoor unit connecting cord 512.

[0065] It can be understood that by arranging the high-voltage wire 202 on the first box wall 112 and the high-voltage wire harness 5 on the second box wall 113, the high-voltage wire 202 and the high-voltage wire harness 5 will not interfere with each other, and the line layout of the high-voltage board 3 can be made closer to the structure of the air conditioner 1000, that is, the high-voltage wire 202 is close to the ventilation and heat exchange component 200 and the high-voltage wire harness 5 is close to the outside of the air conditioner 1000, which is conducive to shortening the length of the line and improving the design rationality of the air conditioner 1000.

[0066] In some embodiments of the present invention, the wire threading hole 1131 is provided at the end of the second box wall 113 close to the box cover 2, and is formed with an opening that opens toward the box cover 2.

[0067] For example, refer to Figure 3-Figure 4As shown, the wire threading hole 1131 can be set at the end of the second box wall 113 close to the box cover 2, so that the wire threading hole 1131 is formed with an opening open toward the box cover 2. When the box cover 2 is opened, the high-voltage electrical harness 5 can be loaded into the wire threading hole 1131 from the opening, and when the box cover 2 is installed to the box body 1, the box cover 2 can close the opening to limit the high-voltage electrical harness 5.

[0068] Among them, a strong electric harness 5 can be provided including a wire body 51 and a clamping portion 52, the clamping portion 52 protruding from the outer peripheral wall of the wire body 51, the clamping portion 52 can be constructed in a rectangular shape, the clamping portion 52 can be inserted into the threading hole 1131 from the open end and positioned with the threading hole 1131 to fix the strong electric harness 5 in the threading hole 1131. At the same time, a strong electric harness 5 can be provided including a power line 511 and an indoor and outdoor unit connection line 512, the power line 511 and the indoor and outdoor unit connection line 512 are arranged in the direction of the box body 1 and the box cover 2 (reference Figure 3 The second direction F2 shown in the figure is arranged sequentially (such as the front-to-back direction shown in the figure).

[0069] It can be understood that by arranging the high-voltage electrical harness 5 to be positioned and matched with the wire threading hole 1131 through the locking portion 52, the wire body 51 can be prevented from being excessively squeezed, which is beneficial to protecting the wire body 51 and improving the reliability of the high-voltage electrical harness 5. By arranging the power cord 511 and the indoor and outdoor unit connecting wires 512 in sequence in the arrangement direction of the box body 1 and the box cover 2, the size of the exposed opening can be reduced, thereby ensuring the matching stability between the high-voltage electrical harness 5 and the wire threading hole 1131 and improving the installation stability of the high-voltage electrical harness 5.

[0072] It can be understood that by installing the high-current board 3 and the low-current board 4 in the first chamber 111 and the second chamber 121 respectively, interference between the high-current board 3 and the low-current board 4 can be avoided, which is beneficial to improving the reliability of the electrical control box 100. By setting the entrance of the first chamber 111 and the entrance of the second chamber 121, they can be opened at the same time when the box cover 2 is opened, which can facilitate later maintenance. Moreover, the structure of the electrical control box 100 is simple and easy to process, which is beneficial to saving processing costs.
