[0044] Figure 1 is a schematic structural diagram of an electrical box according to an embodiment of the utility model, such as Figure 1As shown, and refer to Figures 2 to 8 The embodiment of the utility model provides an air conditioner. The air conditioner includes a casing 100 and an electrical box 200.

[0045] The housing 100 includes a top plate 110, and the housing 100 is electrically connected to the grounding portion of the air conditioner. The electrical box 200 is disposed horizontally and is detachably fixedly connected to the lower side of the top plate 110 by a conductive fastener, so that the electrical box 200 is electrically connected to the grounding portion through the conductive fastener and the housing 100. The grounding portion is grounded.

[0046] In order to ensure the safe use of the air conditioner, all metal parts in the air conditioner need to be grounded. Since there are metal parts in the electrical box 200, the electrical box 200 needs to be grounded.

[0047] In this embodiment, the electrical box 200 is detachably fixedly connected to the lower side of the top plate 110 by a conductive fastener and is electrically connected to the top plate 110 of the housing 100, and the housing 100 is electrically connected to the grounding portion, so that the electrical box 200 is grounded. The structure of grounding the electrical box 200 does not require the use of additional wires to connect the electrical box 200 and the grounding portion to ground the electrical box 200, which simplifies the installation difficulty of the electrical box 200 and the air conditioner, reduces labor costs and material usage costs, and also makes the interior of the housing 100 more tidy, easy to repair and install, improves the ornamental value, and thus improves the user experience. Not using wires to ground the electrical box 200 also avoids the situation where the electrical box 200 cannot be grounded due to the wires being easily broken or falling off, thereby improving the safety performance of the air conditioner.

[0048] Furthermore, the horizontally arranged electrical box 200 is spaced apart from the base plate 300 in the vertical direction, so that the electrical box 200 does not occupy the connection area of ​​the base plate 300, making the installation of components in the air conditioner more compact, reducing the overall volume of the air conditioner, increasing the applicable scenarios of the air conditioner, and improving the user experience.

[0049] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the air conditioner further includes a bottom plate 300 and a first support member 410 .

[0050] The housing 100 is covered on the bottom plate 300. The bottom plate 300 is electrically connected to the ground portion, and the housing 100 is electrically connected to the bottom plate 300.

[0051] The first support member 410 is vertically arranged, and the lower end of the first support member 410 is fixedly connected to the bottom plate 300. The electrical box 200 is detachably fixedly connected to the first support member 410.

[0052] Furthermore, the housing 100 further includes two side panels 120 located at both sides of the top panel 110 and formed integrally with the top panel 110. The housing 100 is covered on the bottom panel 300 from above, and the side panels 120 are fixedly connected to the bottom panel 300.

[0054] In this embodiment, the first support member 410 supports the electrical box 200, reduces the pulling force on the top plate 110 after the electrical box 200 is connected to the top plate 110, improves the connection stability of the electrical box 200, and reduces the deformation of the housing 100 due to excessive force. In addition, the electrical box 200 and the first support member 410 are detachably connected, so that the electrical box 200 can be disassembled for repair or replacement after a failure occurs.

[0055] The electrical box 200 is connected to the housing via a conductive fastener to achieve electrical connection 100, thereby grounding the electrical box 200.

[0056] In some embodiments of the present invention, Figure 8 As shown, the air conditioner further includes a second support member 420, and the second support member 420 is provided with a slot 421 opening toward the side.

[0057] like Figure 2 As shown, a buckle 220 that cooperates with the slot 421 is connected to the bottom of the electrical box 200 .

[0058] In this embodiment, the buckle 220 is inserted into the slot 421 to limit the movement of the electrical box 200 in the vertical direction. The insertion of the buckle 220 into the slot 421 enables the second support member 420 to support the electrical box 200, thereby reducing the pulling force on the top plate 110 after the electrical box 200 is connected to the top plate 110, improving the connection stability of the electrical box 200, and reducing the occurrence of deformation of the casing 100 due to excessive force.

The utility model reduces the use of components, reduces the production and installation costs of the air conditioner. In addition, reducing the use of components can also reduce the volume required for the installation space inside the air conditioner, thereby making the installation of components in the air conditioner more compact, reducing the overall volume of the air conditioner, increasing the applicable scenarios of the air conditioner, and improving the user experience.

[0062] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the electrical box 200 includes a connection plate 210 extending rearward.

Further, the third connection hole 411 is at the top of the first connection member, and the third connection hole 411 is a blind hole.

[0065] In this embodiment, the connecting plate 210 is fixedly connected between the first support member 410 and the top plate 110, and is connected by a conductive fastener to improve the connection stability of the electrical box 200. Moreover, the connection between the housing and the electrical box 200 by the conductive fastener can also make the housing and the electrical box 200 electrically connected, and since the housing is electrically connected to the grounding part, the electrical box 200 is grounded.

[0066] Further, in some embodiments of the present invention, the first connection hole 111 is a through hole, the second connection hole 211 is a threaded hole, the third connection hole 411 is a threaded hole, and the conductive fastener is a screw.
