[0034] The principles and features of the present application will be described below with reference to the accompanying drawings. The examples given are only for explaining the present application and are not intended to limit the scope of the present application.

[0035] The embodiment of the present application provides an electric control box 100, including: a housing assembly and an electric control assembly.

[0036] As Figure 1 and Figure 2 shown, the housing assembly includes a box body 1 and a box cover 2. The box cover 2 is covered on the box body 1 and encloses an installation cavity with the box body 1. The electric control assembly is located in the installation cavity. As Figure 2 shown, the electric control assembly includes an electric control bracket 3 and an electric control board 4 fixed to the electric control bracket 3. The electric control board 4 can be fixed on the electric control bracket 3 by means of fasteners, snap connection, etc.

[0037] Among them, the housing assembly is provided with a snap connection part, and the electric control bracket 3 is provided with a snap connection cooperation part. The snap connection part and the snap connection cooperation part cooperate to fix the electric control bracket 3 to the housing assembly.

[0038] For the electric control box 100 provided by the embodiment of the present application, the electric control board 4 is fixed on the electric control bracket 3, and the electric control bracket 3 and the housing assembly are assembled and fixed through a snap connection structure, indirectly realizing the snap connection and fixation of the electric control board 4 and the housing assembly, replacing the fastener connection method. During maintenance, only the snap connection cooperation between the electric control bracket 3 and the housing assembly needs to be released, thereby reducing the maintenance difficulty of the electric control box 100 and bringing convenience to the maintenance of the electric control board 4.

[0039] Moreover, through the setting of the electric control bracket 3, the electric control board 4 and the housing assembly are indirectly snap-connected and fixed, without the need to provide a snap connection cooperation part on the electric control board 4, thus simplifying the structure of the electric control board 4, facilitating the reasonable arrangement of electronic components on the electric control board 4, and being beneficial to optimizing the layout of the electric control board 4.

[0040] In some exemplary embodiments, the snap connection part includes a convex part 11 provided on the inner side wall of the box body 1, as Figure 3 and Figure 4 shown. The snap connection cooperation part includes a buckle 31 provided on the electric control bracket 3, as Figure 3and Figure 4 As shown, the buckle 31 is snap-fitted with the protrusion 11.

[0041] Of course, the snap-in part and the snap-fitting part are not limited to the structural forms of the protrusion 11 and the buckle 31, and can also be structural forms such as the buckle 31 and the card hole, the hook 35 and the convex bump, etc. The structures of the snap-in part and the snap-fitting part can also be swapped.

[0042] In some exemplary embodiments, the box body 1 is provided with a maintenance opening 12, as Figure 3 shown. The electric control assembly is arranged to be able to be taken out of the box body 1 along the first direction through the maintenance opening 12. The protrusion 11 is provided with a limiting wall surface 111, and the buckle 31 includes a first sub-buckle 311, as Figure 4 shown. The first sub-buckle 311 is arranged to hook the limiting wall surface 111, as Figure 4 shown, so as to limit the movement of the electric control bracket 3 relative to the box body 1 along the first direction.

[0043] This can prevent the electric control assembly from being taken out of the box body 1 along the first direction after being installed in the installation cavity, thus ensuring the stability of the electric control assembly.

[0044] Among them, when the electric control box 100 is applied to ceiling-mounted household appliances (such as air duct machines, central air conditioners), the electric control box 100 is usually located above the maintenance personnel, and the maintenance opening 12 is usually arranged downward, as Figure 4 shown, the limiting wall surface 111 is located at the top of the protrusion 11, the first direction is the downward direction, and the second direction is the upward direction. The maintenance personnel need to take out the electric control assembly downward for maintenance. Therefore, the cooperation between the first sub-buckle 311 and the limiting wall surface 111 can effectively ensure that the electric control assembly will not fall out under the action of gravity and hit the maintenance personnel or fall suspended and damage the equipment after the maintenance opening 12 is opened.

[0045] In some exemplary embodiments, the electric control assembly is arranged to be able to enter the box body 1 along the second direction opposite to the first direction through the maintenance opening 12.

[0046] The protrusion 11 is further provided with a guiding wall surface 112, as Figure 4 shown, the guiding wall surface 112 is connected to the limiting wall surface 111 in a turning manner, and the first sub-buckle 311 is arranged to slide along the guiding wall surface 112 to the limiting wall surface 111 and hook the limiting wall surface 111.

[0047] In this way, after the maintenance is completed, the maintenance personnel can push the electric control assembly into the box body 1 along the second direction. Guided by the sliding fit between the guiding wall surface 112 and the first sub-buckle 311, the sliding process of the electric control assembly will be relatively smooth. When the second sub-buckle 312 crosses the guiding wall surface 112, it can hook the limiting wall surface 111, thereby realizing snap-fitting and fixing.

[0048] In this way, the electronic control component can be maintained by simply pulling it out, which is very convenient.

[0049] In some exemplary embodiments, the buckle 31 further includes a second sub-buckle 312. As Figure 4 shown, a guiding groove 13 is formed between the guiding wall surface 112 and the electronic control bracket 3. The second sub-buckle 312 is located in the guiding groove 13 and abuts against the guiding wall surface 112.

[0050] This can prevent the electronic control component from shaking or skewing in the thickness direction of the electronic control board 4, which is beneficial to improving the smoothness of the sliding of the electronic control component relative to the box body 1 and also beneficial to improving the position stability of the electronic control component after assembly.

[0051] In some exemplary embodiments, as Figure 5 shown, the electronic control bracket 3 includes a bracket main body 32 and a first folding edge 33 connected to the end of the bracket main body 32. The electronic control board 4 is fixed to the bracket main body 32. A guiding groove 13 is formed between the first folding edge 33 and the guiding wall surface 112. The first sub-buckle 311 and the second sub-buckle 312 are arranged on the first folding edge 33, as Figure 5 shown.

[0052] This is beneficial to preventing the bracket main body 32 and the electronic control board 4 from interfering with the protruding portion 11, thereby facilitating the disassembly and assembly of the electronic control component and improving the convenience of disassembly and assembly of the electronic control component.

[0053] In some exemplary embodiments, the guiding wall surface 112 and the limiting wall surface 111 are arranged as inclined surfaces, as Figure 4 shown. The protruding portion 11 is generally a frustum of a pyramid structure. The box body 1 is a sheet metal part, and the protruding portion 11 is formed by inward stamping of the side wall of the sheet metal part.

[0054] In some exemplary embodiments, the number of the protruding portions 11 is multiple, as Figure 6 shown. The multiple protruding portions 11 are respectively arranged on two opposite inner side walls of the box body 1. The number of the buckles 31 is multiple, as Figure 5 shown. The multiple buckles 31 are arranged corresponding to the multiple protruding portions 11. This is beneficial to the balanced force between the electronic control bracket 3 and the box body 1, thereby improving the fixing reliability of the electronic control component.

[0055] In one embodiment, as Figure 5 and Figure 6 shown, the number of the protruding portions 11 is two, and the two protruding portions 11 are symmetrically arranged. The number of the buckles 31 is two, and the two buckles 31 are symmetrically arranged.

[0056] Of course, the number of the protruding portions 11 on the same side can also be multiple, and the number of the buckles 31 on the same side can also be multiple.

[0057] In some exemplary embodiments, as Figure 7 shown, the box body 1 is provided with a first flanging 14, and the box cover 2 is provided with a second flanging 21. The first flanging 14 and the second flanging 21 are arranged at intervals relative to each other in the first direction. The two ends of the electronic control bracket 3 in the first direction are respectively provided with a relatively arranged third flanging 36 and a fourth flanging 37. The third flanging 36 is arranged to be able to abut against the first flanging 14, and the fourth flanging 37 is arranged to be able to abut against the second flanging 21, so that the electronic control bracket 3 is limited between the first flanging 14 and the second flanging 21. The second flanging 21 can cover the inspection opening 12 of the box body 1.

[0058] This can effectively prevent the electronic control component from moving in the installation cavity in the first direction or the second direction (that is, prevent the electronic control component from moving in the up and down direction), thereby effectively ensuring the position stability of the electronic control component.

[0059] The cooperation between the buckle 31 and the protrusion 11 can effectively prevent the electronic control component from moving in the left - right direction and the front - back direction in the installation cavity.

[0060] Among them, the first flanging 14 of the box body 1 can be the top wall of the box body 1, which plays a role in covering the top of the box body 1. The second flanging 21 of the box cover 2 can be the bottom wall of the box cover 2, which plays a role in covering the inspection opening 12 at the bottom of the box body 1. The area of the third flanging 36 of the electronic control bracket 3 can be smaller than that of the first flanging 14, and the area of the fourth flanging 37 can be smaller than that of the second flanging 21, as long as it can play a limiting role.

[0061] In some exemplary embodiments, the electronic control bracket 3 is provided with a hook 35, as Figure 4 and Figure 5 shown, the box body 1 is provided with an installation notch 17, and the hook 35 is inserted into the installation notch 17 and hooks the box body 1, as Figure 4 shown, to limit the relative movement of the electronic control bracket 3 relative to the box body 1 in the third direction. The third direction is perpendicular to the first direction. The third direction can be the front - back direction.

[0062] The hook 35 can be inserted into the installation notch 17 and hook the outer side wall of the box body 1 after the electronic control component slides into the box body 1 in the second direction.

[0063] In some exemplary embodiments, the box cover 2 is arranged to slide - cover the box body 1 in the second direction. The end of the box body 1 in the second direction is provided with a second folding edge 3316, as Figure 6 and Figure 7 shown. The second folding edge 3316 is inclined away from the electronic control component and is arranged to guide the box cover 2 to be installed on the box body 1.

[0064] The second folding edge 3316 can be arranged at one end of the box body 1 away from the inspection opening 12, that is, the upper end.

[0065] In this way, the lid 2 can be removed by pulling and covered by pushing, and then it can be fixedly connected to the box body 1 through fasteners (such as screws). The second folding edge 3316 can effectively ensure that the lid 2 slides in place, playing a good positioning role and guiding role.

[0066] A fifth folding edge 15 can be provided inside the box body 1. As Figure 4 shown, a first connection hole 151 can be provided on the fifth folding edge 15. A second connection hole 211 can be correspondingly provided on the second folding edge 21 of the lid 2. As Figure 2 shown. The fastener passes through the second connection hole 211 and the first connection hole 151 to fixedly connect the lid 2 to the box body 1.

[0067] Among them, the fifth folding edge 15 of the box body 1 can be a small-area folding edge provided at the maintenance opening 12 of the box body, which does not affect the access of the electronic control components.

[0068] As Figure 1 and Figure 2 shown, an embodiment of the present application also provides a fresh air module, including: a fresh air main body and an electronic control box 100 as described in any one of the above embodiments, which is connected to the fresh air main body.

[0069] The fresh air module provided by the embodiment of the present application includes the electronic control box 100 as described in any one of the above embodiments, and thus has all the above beneficial effects.

[0070] In some exemplary embodiments, the fresh air main body may include a housing 5. As Figures 1 to 3 shown, the electronic control box 100 can be located outside the housing 5, and the box body 1 is fixedly connected to the housing 5. The housing 5 can be provided with a fresh air inlet 53, a fresh air outlet and other structures.

[0071] The electronic control bracket 3 is provided with a first wire passing notch 34. As Figure 5 shown. The side wall of the box body 1 close to the housing 5 is provided with an avoidance notch 18. As Figure 6 shown. The housing 5 is provided with a second wire passing notch 51. As Figure 6 shown, the second wire passing notch 51 is correspondingly arranged and communicated with the first wire passing notch 34, and a wire passing rubber part 52 is provided at the second wire passing notch 51. As Figure 3 shown.

[0072] The settings of the first wire passing notch 34 and the second wire passing notch 51 facilitate the connection between the electronic control board 4 and the electrical components inside the fresh air main body through the wire body. The wire passing rubber part 52 is beneficial to preventing the wire body from being cut and also beneficial to improving the sealing performance at the first wire passing notch 34 and the second wire passing notch 51.

[0073] The number of the first wire passing notches 34 can be one or multiple. As Figure 5As shown. The size of the avoidance notch 18 can be relatively large, such as Figure 6 shown, so that most of the bracket body 32 can be directly opposite to the outer shell 5 of the fresh air main body.

[0074] The embodiment of the present application also provides an air conditioner, including: an air conditioner main body (not shown in the figure) and the fresh air module of any one of the above embodiments, and the fresh air module is connected to the air conditioner main body.

[0075] The air conditioner provided by the embodiment of the present application includes the fresh air module of any one of the above embodiments, and thus has all the above beneficial effects, which will not be elaborated here.
