Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0030] like Figure 1 and Figure 2 As shown, in one aspect, this application provides an electrical box 1, which includes a fixed box body 10, a movable box cover 20 and an electrical component mounting plate 30. The electrical box 1 can be disassembled and repaired under different return air installation methods, effectively reducing the difficulty of disassembly and repair during the use of the electrical box 1.

[0031] The fixed box body 10 is formed on a target device, which is a device to which the electric appliance box 1 is applied, and can be different types such as the ducted air conditioner 100, and embodiments of the present application do not limit this. Here, the fixed box body 10 includes a fixed cover 11, which can be formed together on the target device. The fixed box body 10 can be integrally formed with the shell of the target device, or can be separately formed and fixedly installed on the shell of the target device.

[0032] The movable box cover 20 and the fixed box body 10 enclose a device mounting cavity 14, which is used to accommodate an electric appliance element mounting plate 30 and various electric appliance elements. The movable box cover 20 includes a first box cover 21 and a second box cover 22 that are detachably connected, and the first box cover 21 is detachably connected with the fixed cover 11. The electric appliance element mounting plate 30 is arranged in the device mounting cavity 14 and is detachably connected with the fixed box body 10. The electric appliance element mounting plate 30 is used to mount electric appliance elements to form a required control circuit assembly. The specific implementation of the detachable connection can be determined according to actual needs, and can be, for example, a snap connection, a threaded connection, etc., and embodiments of the present application do not limit this.

[0033] When the first box cover 21 and the fixed cover 11 are disconnected, the movable box cover 20 can be separated from the fixed box body 10 in a first direction to open the device mounting cavity 14. After the device mounting cavity 14 is opened, the electric appliance element mounting plate 30 can be inserted into or withdrawn from the device mounting cavity 14 in the first direction, achieving mounting and dismounting of the electric appliance element mounting plate 30 in the first direction.

[0034] When the first box cover 21 and the fixed cover 11 remain connected, but the first box cover 21 and the second box cover 22 are disconnected, the second box cover 22 can be separated from the first box cover 21 in a second direction to open the device mounting cavity 14. After the device mounting cavity 14 is opened, the electric appliance element mounting plate 30 can be inserted into or withdrawn from the device mounting cavity 14 in the second direction, achieving mounting and dismounting of the electric appliance element mounting plate 30 in the first direction. Here, the first direction and the second direction are arranged perpendicularly or at an angle. The specific directions of the first direction and the second direction can be determined according to actual needs, and embodiments of the present application do not limit this; in some embodiments, the first direction is the up-down direction, and the second direction is the front-back direction.

[0035] When the electric appliance box 1 provided in embodiments of the present application is applied to the ducted air conditioner 100, the first direction can be the up-down direction, and the second direction can be the front-back direction. For example, Figures 1 to 2 and Figure 6As shown, when the ducted air conditioner 100 adopts the lower return air installation mode, the first cover 21 and the fixed cover 11 can be disconnected, the movable cover 20 can be separated from the fixed cover 10 in the downward direction to open the device installation cavity 14, so that the lower side area of the device installation cavity 14 is opened, and then the electrical component mounting plate 30 can be inserted into or withdrawn from the device installation cavity 14 in the upward or downward direction, thereby achieving the installation and disassembly of the electrical component mounting plate 30 in the lower return air installation mode. As shown, Figures 1 to 2 and Figure 7 As shown, when the ducted air conditioner 100 adopts the rear return air installation mode, the first cover 21 and the fixed cover 11 can be connected, and the first cover 21 and the second cover 22 can be disconnected, the movable cover 20 can be separated from the fixed cover 10 in the rear direction to open the device installation cavity 14, so that the rear side area of the device installation cavity 14 is opened, and then the electrical component mounting plate 30 can be inserted into or withdrawn from the device installation cavity 14 in the forward or rearward direction, thereby achieving the installation and disassembly of the electrical component mounting plate 30 in the rear return air installation mode. In this way, the electrical box 1 can be disassembled and repaired in different return air installation modes, effectively reducing the difficulty of disassembly and repair of the electrical box 1 during use.

[0036] In some embodiments, the fixed cover 10 can further include a first fixed side plate 12 and a second fixed side plate 13. The fixed cover 11, the first fixed side plate 12 and the second fixed side plate 13 are adjacent to each other, that is, the fixed cover 11 is fixedly connected with the first fixed side plate 12 and the second fixed side plate 13 respectively, and the first fixed side plate 12 and the second fixed side plate 13 are fixedly connected. The second cover 22 and the second fixed side plate 13 are relatively spaced apart in the second direction, and the electrical component mounting plate 30 is detachably mounted on the second fixed side plate 13. When the first cover 21 and the fixed cover 11 are connected, the fixed cover 11, the first fixed side plate 12, the second fixed side plate 13, the first cover 21 and the second cover 22 form a device installation cavity 14, and the electrical component mounting plate 30 is accommodated in the device installation cavity 14.

[0037] As shown, Figures 1 to 5 In some examples, the first cover 21 can include a first movable cover plate 211 and a second movable cover plate 212 fixedly connected. The first movable cover plate 211 and the first fixed side plate 12 are relatively spaced apart, the second movable cover plate 212 and the fixed cover 11 are relatively spaced apart in the first direction, and the first movable cover plate 211 and the second movable cover plate 212 are connected vertically or at an angle. For example, the first direction can be the up-down direction, and correspondingly, the fixed cover 11 can be a top cover, and the second movable cover plate 212 can be a bottom cover.

[0038] In some examples, the electric appliance box 1 can further include an adapter 40. The adapter 40 has a first connecting wall 41 and a second connecting wall 42 which are connected vertically or at an angle. The first connecting wall 41 is provided with a first threaded hole 411, and the electric element mounting plate 30 is provided with a first through hole 32. A first threaded fastener 50 is connected to the first threaded hole 411 after passing through the first through hole 32, so that the adapter 40 and the electric element mounting plate 30 are fixedly connected. The second connecting wall 42 is provided with a second through hole 421, and the first fixed side plate 12 is provided with a second threaded hole 121. A second threaded fastener 60 is connected to the second threaded hole 121 after passing through the second through hole 421, so that the adapter 40 and the first fixed side plate 12 are fixedly connected. Here, the first threaded fastener 50 and the second threaded fastener 60 can be bolts respectively. In this way, the electric element mounting plate 30 can be fixed to the first fixed side plate 12 through the adapter 40, and the electric element mounting plate 30 and the second fixed side plate 13 are detachably connected, so that the electric element mounting plate 30 is reliably and stably mounted in the element mounting cavity 14.

[0039] The detachable connection structure of the electric element mounting plate 30 and the second fixed side plate 13 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some examples, the second fixed side plate 13 can be provided with a mounting clamping groove 131. One end of the electric element mounting plate 30 can be provided with a clamping hook portion 31, which is clamped with the mounting clamping groove 131, so that the electric element mounting plate 30 is mounted on the second fixed side plate 13. In this way, the electric element mounting plate 30 and the second fixed side plate 13 adopt a buckle connection structure, which facilitates installation and disassembly of the two, and reduces the difficulty of disassembly.

[0040] For example, the clamping hook portion 31 can include a guide folding edge portion 311, an assembly folding edge portion 312 and a root folding edge portion 313 connected in sequence. The root folding edge portion 313 is bent and formed at one end edge of the electric element mounting plate 30, and the guide folding edge portion 311 is arranged at an angle with the assembly folding edge portion 312 and the root folding edge portion 313. When the clamping hook portion 31 and the mounting clamping groove 131 are clamped, the guide folding edge portion 311 can be inserted into the mounting clamping groove 131 first, and the surface of the guide folding edge portion 311 and the side wall of the mounting clamping groove 131 form an abutting guide effect, guiding the assembly folding edge portion 312 of the clamping hook portion 31 to gradually penetrate into the mounting clamping groove 131; when the clamping hook portion 31 and the mounting clamping groove 131 are clamped, the assembly folding edge portion 312 abuts and limits the side wall of the mounting clamping groove 131, so that the clamping hook portion 31 is stably clamped in the mounting clamping groove 131, avoiding shaking and accidental falling of the clamping hook portion 31.

[0041] In some embodiments, the electrical component mounting plate 30 can be provided with a handle portion 33. An operator can pull the electrical component mounting plate 30 through the handle portion 33 to mount and dismount the electrical component mounting plate 30 on the fixed box body 10. In some examples, the electrical component mounting plate 30 can be provided with a hook portion 31 and a handle portion 33, which can be arranged at opposite ends of the electrical component mounting plate 30.

[0042] In some embodiments, the first box cover 21 can have a box cover body 2111 and a limiting spring 2112. One end of the limiting spring 2112 is connected to the box cover body 2111, and the other end of the limiting spring 2112 extends in a direction close to the fixed cover 11 and is spaced apart from the box cover body 2111. Correspondingly, the fixed cover 11 can be provided with a first folded edge portion 111. When the first box cover 21 is connected to the fixed cover 11, the first folded edge portion 111 is embedded between the box cover body 2111 and the limiting spring 2112, and the limiting spring 2112 is used to tightly press the first folded edge portion 111 against the surface of the box cover body 2111, so that the first box cover 21 and the fixed cover 11 are reliably connected.

[0043] In some embodiments, the second box cover 22 can be provided with an extended edge portion 221 close to one end of the fixed cover 11, which extends in a direction close to the fixed cover 11. Correspondingly, the fixed cover 11 can be provided with a second folded edge portion 112. When the movable box cover 20 is connected to the fixed cover 11, the second folded edge portion 112 blocks the extended edge portion 221, and the extended edge portion 221 is inserted into the back side of the second folded edge portion 112 to realize the positioning between the second box cover 22 and the fixed cover 11.

[0044] As shown in FIG. 1, Figures 1 to 7 In some embodiments, the target device can be a ducted air conditioner 100. The ducted air conditioner 100 is provided with a first return air inlet 2 and a second return air inlet 3. The first return air inlet 2 is opened in a first direction, and the second return air inlet 3 is opened in a second direction. The fixed box body 10 is arranged adjacent to the first return air inlet 2 and the second return air inlet 3, respectively. In some examples, the first direction can be the up-down direction, so that the first return air inlet 2 can be a lower return air inlet. The second direction can be the front-rear direction, so that the second return air inlet 3 can be a rear return air inlet.

[0045] On the other hand, the embodiments of the present application provide a ducted air conditioner 100, which includes the electrical appliance box 1 provided by any of the above embodiments. The ducted air conditioner 100 provided by the embodiments of the present application has the above-mentioned electrical appliance box 1, which can be disassembled and repaired under different return air installation modes, effectively reducing the difficulty of disassembly and repair of the electrical appliance box 1 during use.
