Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an electric control box assembly and an air conditioner. Background Art

[0002] At present, electric control boxes have been widely used in many air conditioners, such as duct air conditioners. In the prior art, there are two main designs of electric control boxes for duct air conditioners. One is a built-in electric control box arranged inside the duct air conditioner, so that the main board and wiring terminals of the duct air conditioner are located inside it. When performing engineering wiring or main board maintenance, it is necessary to open the side wall of the duct air conditioner first, and then open the electric control box cover to perform wiring and maintenance operations; the other is an external electric control box arranged outside the duct air conditioner. Although it does not need to open the side wall of the duct air conditioner to perform engineering wiring or main board maintenance operations, its main board and wiring terminals are usually arranged together. When the electric control box cover is opened for engineering wiring installation, its main board and other important components are exposed to the outside, and improper operation of the staff may cause damage to the main board, thereby causing the duct air conditioner to fail to operate normally.

[0036] In addition, all directions or positional relationships mentioned in the embodiments of the present invention are based on the positional relationships in the accompanying drawings, and the directions or positional relationships indicated by terms such as "up", "down", "left", "right", "front", "back", "inside" and "outside" are only simplified descriptions for the convenience of understanding the present invention, and do not imply that the referred device or element must have a specific orientation, and cannot be understood as a limitation on the present invention.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0038] Figure 1 It is a schematic diagram of the front structure of an air conditioner involved in an embodiment of the present invention.

[0039] Figure 1 The structure diagram of the air conditioner involved in this embodiment is schematically shown, and the description of other structures is omitted in the following description. In this embodiment, the type of the air conditioner 1 is not particularly limited, for example, it can be an indoor unit or a duct unit. Figure 1 As shown, the air conditioner 1 involved in this embodiment may include an electric control box assembly 11, wherein the electric control box assembly 11 may include an inner electric control box 111 arranged on the inner side of the air conditioner 1 and suitable for installing the main board assembly of the air conditioner 1, and an outer electric control box 112 arranged on the outer side of the air conditioner 1 and suitable for installing the wiring assembly 15 of the air conditioner 1.

[0040] In this embodiment, the electric control box assembly is divided into an inner electric control box and an outer electric control box, and the main board assembly and the wiring assembly of the air conditioner are installed separately, thereby achieving separation of the main board assembly and the wiring assembly, that is, during engineering wiring, only the outer electric control box needs to be opened to complete the work, and when the main board needs to be repaired, the inner electric control box can be opened, thereby avoiding accidental damage to the main board assembly during engineering wiring; and, by arranging the inner electric control box on the inner side of the air conditioner and the outer electric control box on the outer side of the air conditioner, during engineering wiring, only the cover of the outer electric control box needs to be opened without opening the side wall of the air conditioner, thereby achieving engineering wiring operation, thereby simplifying the operating process and preventing damage to the side wall of the air conditioner when the side wall of the air conditioner is opened, thereby increasing the maintenance cost and the like.

[0041] Figure 2 is a schematic diagram of the side structure of an air conditioner involved in an embodiment of the present invention, Figure 3 It is another front structural schematic diagram of the air conditioner involved in the embodiment of the present invention.

[0042] In this embodiment, if Figure 2 and Figure 3 As shown, the side wall 12 of the air conditioner 1 may be provided with a side panel opening 121, and the outer electric control box 112 may include an isolation plate 1121 and an outer box cover 1122. In some examples, the isolation plate 1121 may be installed on the side wall 12 of the air conditioner 1 and located at the side panel opening 121. In other examples, the openings of the inner electric control box 111 and the outer box cover 1122 may both face the side panel opening 121, and the isolation plate 1121 may be located between the inner electric control box 111 and the outer box cover 1122. In this case, by setting an isolation plate between the inner electrical control box and the outer box cover of the outer electrical control box, the mainboard assembly and the wiring assembly of the air conditioner can be effectively separated. Therefore, when performing engineering wiring, it is only necessary to open the outer box cover. When the mainboard assembly needs to be inspected, the isolation plate is opened to expose the side panel opening to expose the mainboard assembly in the inner electrical control box, thereby realizing the repair or replacement of the mainboard assembly. Therefore, there is no need to open the side wall of the air conditioner to realize the inspection of the mainboard assembly, which further simplifies the operating process and further prevents damage to the side wall of the air conditioner when the side wall of the air conditioner is opened, thereby increasing the maintenance cost.

[0043] In addition, in this embodiment, there is no particular restriction on the installation position of the outer box cover 1122. In some examples, the outer box cover 1122 can be installed on the outer side wall of the air conditioner 1, or on the isolation plate 1121. In other examples, the outer box cover 1122 can be installed on the outer side wall of the air conditioner 1 on one side and on the isolation plate 1121 on the other side. Thus, according to the requirements of the accommodation space of the wiring assembly, etc., different sizes of outer box covers can be set, and the outer box cover can be fixedly installed on the outer side wall of the air conditioner or the isolation plate to achieve the closed protection of the wiring assembly.

[0044] In addition, in this embodiment, there is no particular limitation on the fixing and installation method of the outer box cover 1122. In some examples, the outer box cover 1122 can be fixedly installed by screws. In other examples, screws or threaded holes can be respectively provided on both sides of the outer box cover 1122, such as the left and right sides, and threaded holes or screws are provided on the outer side wall of the air conditioner 1 or the isolation plate 1121 accordingly. In this way, the fixing and installation of the outer box cover can be formed more conveniently and effectively.

[0045] In addition, in this embodiment, there is no particular limitation on the installation position of the isolation plate 1121. In some examples, the isolation plate 1121 can be installed on the outer wall of the air conditioner 1. In other examples, the isolation plate 1121 can also be installed on the inner wall of the air conditioner 1. Thus, different installation positions can be set according to different application environments to meet different application requirements.

[0046] In addition, in this embodiment, the outer box cover 1122 may be provided with a wire inlet 1126. There is no particular limitation on the size and location of the wire inlet 1126. In this case, the engineering wire connected to the wiring assembly of the air conditioner can be exposed through the wire inlet to facilitate connection with external devices, such as connection with an external power supply.

[0047] Figure 4 It is a schematic diagram of the top structure of the air conditioner involved in the embodiment of the present invention.

[0048] In this embodiment, if Figure 4 As shown, the inner electric control box 111 may include an air guide slope structure 1111 facing the air inlet 13 of the air conditioner 1. In some examples, the air guide slope structure 1111 may be inclined from one end close to the outer electric control box 112 to one end close to the centrifugal fan 14 of the air conditioner 1. In this case, on the one hand, the air inlet area of ​​the centrifugal fan of the air conditioner can be increased, and on the other hand, the airflow at the air inlet of the air conditioner can be guided to flow in the direction of the centrifugal fan, effectively preventing the occurrence of airflow vortex or irregular movement, thereby effectively reducing the noise of the centrifugal fan and improving the comfort of use of the air conditioner with the electric control box assembly.

[0049] In this embodiment, the inclination angle of the wind guide slope structure 1111 is α, wherein the value range of the inclination angle α is not particularly limited. In some examples, the value range of the inclination angle α can be 30° to 75°, such as 35°, 40°, and 65°. In other examples, the value range of the inclination angle α can also be 45° to 60°, such as 50°, 55°, and 58°. In this case, the air inlet area of ​​the centrifugal fan can be more effectively increased, for example, the air inlet area is increased by at least 17% or at least 25%, and the inner electrical control box can be ensured to have sufficient space and height to accommodate the mainboard assembly.

[0050] In this embodiment, a heat dissipation hole 1112 may be provided on the wind guide inclined surface structure 1111. There is no particular limitation on the size and structure of the heat dissipation hole 1112. In some examples, the heat dissipation hole 1112 may be a regular shape, such as a circle or a square, or an irregular shape, or a combination of a regular shape and an irregular shape. In other examples, the heat dissipation hole 1112 may be a circular hole with a diameter of 1 mm. Thus, the hot air in the inner electric control box may flow out through the heat dissipation hole, and when the air enters the air inlet of the air conditioner, it may flow away with the air intake air flow, thereby taking away the heat in the inner electric control box, so as to achieve the purpose of dissipating the heat for the mainboard assembly in the inner electric control box.

[0051] In addition, in this embodiment, there is no particular limitation on the distribution of the heat dissipation holes 1112. In some examples, the heat dissipation holes 1112 may be distributed in an array of regular shapes, such as a circular array or a square array, or may be distributed in an array of irregular shapes, or a combination of regular and irregular arrays. In other examples, the heat dissipation holes 1112 may be distributed in a square array with a spacing of 2 mm. Thus, heat dissipation holes of different shapes and sizes may be provided according to actual needs to meet different application requirements.

[0052] Figure 5 is another side structural schematic diagram of an air conditioner involved in an embodiment of the present invention, Figure 6 for Figure 5 A partial enlarged view of point A in the middle.

[0053] In this embodiment, if Figure 5 As shown, a wire hole 1124 may be provided on the isolation plate 1121. There is no particular restriction on the location of the wire hole 1124, and it may be provided at different locations according to actual needs. Thus, the mainboard assembly in the inner electric control box and the wiring assembly of the outer electric control box may be electrically connected through the wire hole.

[0054] In addition, in this embodiment, the manner in which the isolation plate 1121 is mounted on the side wall 12 of the air conditioner 1 is not particularly limited. In some examples, the isolation plate 1121 can be fixedly mounted on the side wall 12 of the air conditioner 1 by screws, or can be mounted on the side wall 12 of the air conditioner 1 by buckles, etc. In other examples, the isolation plate 1121 can be fixedly mounted on the side wall 12 of the air conditioner 1 by screws on the one hand, and can be clamped on the side wall 12 of the air conditioner 1 by the cooperation of buckles and clamping holes on the other hand. Thus, the isolation plate can be fixedly mounted on the side wall of the air conditioner by screws to close the inner electric control box and prevent the exposure of the main board assembly installed in the inner electric control box, etc., and the isolation plate can be rotatably mounted on the side wall of the air conditioner by the cooperation of buckles and clamping holes. After removing the screws, the isolation plate can be rotated around the side wall of the air conditioner to open or close the inner electric control box without disassembling the isolation plate.

[0055] In this embodiment, the isolation plate 1121 can be rotatably connected to the side wall 12 of the air conditioner 1. Thus, the isolation plate can be opened or closed more conveniently and effectively, thereby realizing the opening or closing of the inner electric control box, simplifying the process of engineering wiring or mainboard maintenance, and improving work efficiency.

[0056] In this embodiment, if Figure 6 As shown, the rotatable connection between the isolation plate 1121 and the side wall 12 of the air conditioner 1 can be achieved by the cooperation of the first buckle 122 and the first clamping hole 1123. Among them, the setting positions of the first buckle 122 and the first clamping hole 1123 are not particularly limited. In some examples, the side wall 12 of the air conditioner 1 may be provided with a first buckle 122, and the isolation plate 1121 may be provided with a first clamping hole 1123, and the first buckle 122 cooperates with the first clamping hole 1123 so that the isolation plate 1121 can rotate around the side wall 12 of the air conditioner 1. In other examples, the side wall 12 of the air conditioner 1 may be provided with a first clamping hole 1123, and the isolation plate 1121 may be provided with a first buckle 122, and the first buckle 122 cooperates with the first clamping hole 1123 so that the isolation plate 1121 can rotate around the side wall 12 of the air conditioner 1. Thus, through the cooperation of the first clip and the first clip hole, a rotatable connection can be formed between the isolation plate and the side wall of the air conditioner, that is, the isolation plate can rotate around the side wall of the air conditioner, thereby realizing operations such as opening or closing the internal electrical control box.

[0057] 7( a ) and ( b ) are schematic structural diagrams of the isolation plate of the electric control box assembly before and after rotation according to an embodiment of the present invention.

[0058] In this embodiment, the shape structure of the first buckle 122 is not particularly limited. In some examples, the first buckle 122 can be a Z-shaped buckle. Here, the so-called Z-shaped buckle is not limited to the angle relationship of each side must be maintained at a specific angle (such as 45°, etc.), but generally refers to a shape structure with more than three bending edges, and the so-called Z-shaped buckle is only a shape structure observed from a certain angle, and it can also be an N-shaped buckle when observed from other angles. In other examples, as shown in Figures 7 (a) and (b), the first buckle 122 may include a first bending edge 1221 and a second bending edge 1222, wherein before the isolation plate 1121 rotates, the first clamping hole 1123 may be located on the first bending edge 1221 or the second bending edge 1222; after the isolation plate 1121 rotates, the first clamping hole 1123 may be located on the second bending edge 1222 or the first bending edge 1221 accordingly. In this case, by clamping the first card hole on the first buckle, the isolation plate can be stably installed. When the isolation plate needs to be removed, the first buckle only needs to be withdrawn from the first card hole. In this way, the isolation plate can be easily installed, disassembled or rotated without the need for other complicated operations, such as screw tightening or disassembly, thereby simplifying the installation process of the isolation plate, that is, simplifying the preparation and installation process of the electrical control box assembly.

[0059] In addition, in this embodiment, the number and location of the first buckle 122 and the first clamp hole 1123 are not particularly limited. In some examples, there may be more than two first buckles 122 and first clamp holes 1123. In other examples, the first buckle 122 or the first clamp hole 1123 may be disposed on one side of the isolation plate 1121. Thus, the rotatable connection of the isolation plate on the side wall of the air conditioner can be realized more conveniently and effectively.

[0060] In addition, in this embodiment, the first buckle 122 may further include a third bent edge 1223. In some examples, the third bent edge 1223 is located at the outermost side, that is, when the first clamping hole 1123 is clamped on the first buckle 122, it should first pass through the third bent edge 1223, and when the first clamping hole 1123 is removed from the first buckle 122, it should finally pass through the third bent edge 1223. Therefore, by arranging the third bent edge at the outermost side of the first buckle, the isolation plate can be prevented from falling off from the first buckle before and after rotation, so as to improve the stability of the rotational connection between the isolation plate and the side wall of the air conditioner.

[0061] Figure 8 is a schematic diagram of the inner side structure of an air conditioner involved in an embodiment of the present invention, Fig. 9 for Figure 8 A partial enlarged view of point B in the middle.

In some examples, a card connector 1113 may be provided on the inner side wall of the air conditioner 1, and a card slot 123 may be provided on the inner electric control box 111, and the card slot 123 may match the card connector 1113. Thus, through the cooperation of the card connector and the card slot, the positioning installation of the inner electric control box on the side wall of the air conditioner can be achieved.

[0063] In addition, in this embodiment, matching threaded holes may be provided on the inner wall of the air conditioner 1 and the inner electric control box 111, and screws may be used to fix the inner electric control box 111 on the inner wall of the air conditioner 1. Thus, the inner electric control box may be installed on the inner side of the air conditioner more effectively and conveniently.
