[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0026] Figure 2 and Figure 3 The embodiment of the electrical box of the present invention is shown, and the electrical box includes a support frame 10 and a mainboard mounting frame 20, and the mainboard mounting frame 20 is slidably mounted on the support frame 10, and the mainboard mounting frame 20 can slide out relative to the support frame 10. When installed and used, the support frame 10 is used to be fixedly connected to the air conditioner body, and the mainboard mounting frame 20 is used to install the mainboard.

[0027] By applying the technical solution of the present invention, the main board can be installed upside down on the main board mounting frame 20. When it is necessary to check the condition of the main board, or when it is necessary to install and maintain the main board, the main board mounting frame 20 can be pulled out relative to the support frame 10 and pulled out from the air conditioner body to avoid the obstruction of the copper pipe directly below the main board and the compressor, thereby facilitating inspection and maintenance.

[0028] like Figure 2 As shown, in the technical solution of this embodiment, the mainboard mounting frame 20 is also hingedly connected to the support frame 10, and the mainboard mounting frame 20 can be flipped relative to the support frame 10. The position and shape of the mainboard on the air conditioner body can be changed, and it can be inverted and face downward, or flipped and face the air. When the air conditioner body is working normally, the front of the mainboard faces downward, so dust will not fall on the ports and components on the front of the mainboard, which plays a role in preventing dust from falling. When installing or maintaining the electrical box, the front of the mainboard can be flipped to face the air, so that the installer or maintenance personnel can directly operate with both hands on the air conditioner body without disassembling the entire electrical box components, so the efficiency of plugging and removing wires and maintaining the electrical box components is greatly improved.

[0029] As a more preferred embodiment, Figure 3 As shown, a slide groove 11 is provided on the support frame 10, and a sliding support structure 21 matching the slide groove 11 is provided on the mainboard mounting frame 20, and the sliding support structure 21 can slide in the slide groove 11 and can rotate relative to the slide groove 11. Optionally, in the technical solution of this embodiment, the sliding support structure 21 is a hook, and the mainboard mounting frame 20 is suspended on the slide groove 11 through the hook. The hook-shaped sliding support structure 21 can not only play a role of limiting sliding with the slide groove 11, but also limit the left and right movement of the electrical box.

[0030] Preferably, in the technical solution of this embodiment, the slide groove 11 includes a sliding section 111 and a flip section 112, the sliding support structure 21 and the sliding section 111 can be slidably matched, and the sliding support structure 21 and the flip section 112 can be rotatably matched. Figure 2 As shown, when in use, the sliding support structure 21 and the sliding section 111 can slide together to allow the motherboard mounting frame 20 to be pulled out relative to the support frame 10, and then when the sliding support structure 21 reaches the flip section 112, it can rotate in coordination with the flip section 112 to allow the motherboard mounting frame 20 to flip to a position that is convenient for maintenance and installation.

[0031] like Figure 3 As shown, in the technical solution of this embodiment, the sliding section 111 is a straight groove structure. Figure 3 As shown, in the technical solution of this embodiment, it is more preferred that the end of the sliding section 111 away from the flip section 112 has a downward inclination structure of 2° to 5°, so that when the electrical box is in a normal working state, the sliding support structure 21 and the edge of the straight groove structure are interference fit, and the mainboard mounting frame 20 and the support frame 10 are tightly attached, and the two will not be relatively displaced, and no noise will be generated. As other optional implementations, a tapered structure or a shrinking structure is formed at the end of the sliding section 111 away from the flip section 112, which can also achieve the above-mentioned technical effects.

[0032] like Figure 3 and Figure 5 As shown, as a preferred implementation, in the technical solution of this embodiment, a hook-shaped sliding support structure 21 cooperates with the slide slot 11, and a flip section 112 of an arc-shaped slot structure is provided at the end of the sliding section 111 of the straight slot structure, and a limiting boss 113 at the flip section 112 cooperates with the mainboard mounting frame 20 to limit the position. When in use, the board mounting frame 20 is first operated to move along the sliding section 111. When the sliding support structure 21 moves to the flip section 112, it is blocked by the limiting boss 113. Under the action of gravity, the board mounting frame 20 can be flipped to a position that is easy to operate. In the technical solution of this embodiment, as shown in FIG. Figure 3 As shown, the shape of the slide groove 11 is approximately "R"-shaped.

[0033] like Figure 2 As shown, in the technical solution of this embodiment, a limiting boss 113 is formed on the arc groove structure to limit the flipping of the sliding support structure 21. The limiting boss 113 can limit the position of the motherboard mounting frame 20, so that the motherboard mounting frame 20 stays in a position that is convenient for operation, and the limiting boss 113 can keep the motherboard mounting frame 20 stable and stable in the operating position.

[0034] like Figure 4 and Figure 5As shown in FIG. 1 , as a preferred embodiment, a support portion 22 is provided on the other side of the mainboard mounting frame 20 away from the support frame 10, and the support portion 22 is used to support and cooperate with the air conditioner body. In this way, whether in a normal state or in a maintenance state, the support portion 22 and the support frame 10 can cooperate to provide more stable support for the mainboard mounting frame 20. In the preferred technical solution of this embodiment, as Figure 3 As shown, the support portion 22 is a folded edge structure formed on the edge of the mainboard mounting frame 20, and the folded edge structure can limit the left and right movement of the electrical box.

[0035] like Figure 2 and Figure 4 As shown, in the technical solution of this embodiment, the support frame 10 includes a power wiring board mounting frame 10a and a connecting frame 10b connected to the power wiring board mounting frame 10a, the mainboard mounting frame 20 is slidably matched with the power wiring board mounting frame 10a, and the connecting frame 10b is fixedly connected to the air conditioner body. When in use, the support frame 10 is fixedly connected to the air conditioner body to realize the support frame 10, and the power wiring board mounting frame 10a can also be used to install the power wiring board.

[0036] like Figure 3 and Figure 4 As shown, more preferably, in the technical solution of this embodiment, the connecting frame 10b can be arranged at an angle relative to the power wiring board mounting frame 10a. This facilitates the fixed connection of the connecting frame 10b with the air conditioner body, and also allows the power wiring board mounting frame 10a to be tilted upward relatively. More preferably, an opening can also be opened at a position corresponding to the power wiring board mounting frame 10a on the air conditioner body, so as to facilitate the operation of the power wiring board on the power wiring board mounting frame 10a.

[0037] In addition to the above-mentioned embodiment, in another embodiment, the flip section 112 may not be provided, so that the mainboard mounting frame 20 only has the function of being pulled out, and can also avoid the obstruction of the copper pipe and the compressor directly below the mainboard to a certain extent, thereby facilitating inspection and maintenance.

[0038] Preferably, in the technical solution of this embodiment, the support frame 10 and the mainboard mounting frame 20 can be made of sheet metal, and the thickness of the steel is preferably above 0.95 mm to ensure sufficient strength.

[0039] like Figure 4 and Figure 5 As shown, the present invention also provides an air conditioner, which includes the above-mentioned electrical appliance box. By using the above-mentioned electrical appliance box, the electrical components of the air conditioner can be easily installed and maintained.

[0040] like Figure 4 and Figure 5As shown, the air conditioner includes a side panel 31 and a partition 32. During use, the support frame 10 is fixedly connected to the side panel 31, and the mainboard mounting frame 20 is supported on the partition 32. As another optional embodiment, the mainboard mounting frame 20 can also be directly fixed on the injection molded part on the partition 32.

[0041] From the above content, it can be seen that the structure of the electrical box of the present invention, when the mainboard is installed facing downward, can greatly improve the work efficiency when the operator needs to perform disassembly and assembly work such as plugging and removing wires or maintenance work of the electrical box compared to the existing structure. The technical solution of the present invention effectively solves the problems of difficult wiring, difficult disassembly and difficult maintenance in the electrical boxes of the mainboard installed inverted in the prior art.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the embodiments of the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
