DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the description.

[0034] The present invention discloses an electrical appliance box, comprising: a box body 10 and a box cover 20, wherein the box body 10 has an opening 11, and the box body 10 is provided with a waterproof flange 12 bent outward at the position of the opening 11; the box cover 20 is provided with a waterproof groove 21 matching the waterproof flange 12, and after the box cover 20 is assembled on the box body 10, the waterproof flange 12 is located in the waterproof groove 21 to form a waterproof structure. The electrical appliance box of the present invention, by providing the waterproof flange 12 and the waterproof groove 21, after the box cover 20 is assembled on the box body 10, the waterproof flange 12 is located in the waterproof groove 21 to form a waterproof structure, replacing the original sponge sealing structure, thereby effectively avoiding the problem of sealing failure caused by aging of the sponge, improving the service life of the electrical appliance box, and making the electrical appliance box more reliable.

[0035] In the above embodiment, there are multiple waterproof flanges 12, and the multiple waterproof flanges 12 are arranged along the circumference of the box body 10, and two adjacent waterproof flanges 12 are connected by full welding. The electrical box of the present invention is connected by full welding of two adjacent waterproof flanges 12, so that the joints between the waterproof flanges 12 are completely welded, thereby preventing rainwater or accumulated water from penetrating from the joints, thereby increasing the sealing effect.

[0036] In the above embodiment, the box cover 20 has a plurality of inner folds formed on the edge, and the plurality of inner folds cooperate to form a waterproof groove 21. The box cover 20 has an inner side surface 22 facing the box body 10 after assembly, and the inner fold is a bending structure formed by bending the edge of the box cover 20 toward the inner side surface 22. The electrical box of the present invention forms an inner fold by bending the box cover 20 toward the inner side surface 22, so that the plurality of inner folds cooperate to form a waterproof groove 21, which can cooperate with the waterproof flange 12 to form a waterproof structure, avoid rainwater or accumulated water from penetrating, increase the service life of the electrical box, and make the electrical box more reliable.

[0037] In the above embodiment, two adjacent inner folds are connected by full welding. The electrical box of the present invention is connected by full welding of two adjacent inner folds, so that the seams between the inner folds are completely welded, thereby preventing rainwater or accumulated water from penetrating from the seams, thereby increasing the sealing effect.

[0038] In the above embodiment, the box cover 20 is rectangular, and the multiple inner folds include two first inner folds 21a arranged opposite to each other and a second inner fold 21b connected between the two first inner folds 21a; the two first inner folds 21a correspond to the waterproof groove 21, forming a guide structure when the box cover 20 is assembled with the box body 10. The electrical box of the present invention forms a guide structure when the box cover 20 is assembled with the box body 10 by arranging the first inner fold 21a and the second inner fold 21b opposite to each other on the box cover 20, thereby facilitating installation and disassembly.

[0039] In the above embodiment, the second inner fold 21b corresponds to the waterproof groove 21, forming a limiting structure when the box cover 20 is assembled with the box body 10. By forming the limiting structure on the second inner fold 21b, the box body 10 and the box cover 20 can be limited and matched after assembly, thereby improving reliability.

[0040] In the above embodiment, a first limiting portion 23 is provided on the second inner fold 21 b ; a second limiting portion 13 matching the first limiting portion 23 is provided on the box body 10 , and the first limiting portion 23 and the second limiting portion 13 are engaged and limited.

[0041] In the above embodiment, the first limiting portion 23 is a card slot on the second inner fold 21b, and the opening direction of the card slot is opposite to the insertion direction of the box body 10. The electrical box of the present invention is provided with a card slot on the second inner fold 21b, and the opening direction of the card slot is opposite to the insertion direction of the box body 10, so that the box body 10 can be inserted to the end and engage with the card slot for limiting, so as to facilitate installation and removal.

[0042] In the above embodiment, the first end of the first inner fold 21a is connected to the second inner fold 21b, and the second end forms the installation opening 211 of the waterproof groove 21, and the waterproof flange 12 is assembled into the waterproof groove 21 through the installation opening 211. The electrical box of the present invention forms the installation opening 211, and when assembling, the waterproof flange 12 on the box body 10 is inserted into the waterproof groove 21 from the installation opening 211, and the waterproof flange 12 and the waterproof groove 21 are slidably matched, so that the box cover 20 is assembled by sliding the cover to the opening of the box body 10, thereby facilitating installation and disassembly, and after assembly, it can effectively prevent water from entering, and at the same time, no sponge is required, and hidden dangers are eliminated to ensure the effectiveness and reliability of sealing.

[0043] In the above embodiment, the box cover 20 is provided with a first limiting portion 23; the box body 10 is provided with a second limiting portion 13 matching the first limiting portion 23, and the first limiting portion 23 and the second limiting portion 13 are engaged and limited. The electrical box of the present invention is engaged by the first limiting portion 23 and the second limiting portion 13, so that the box body 10 and the box cover 20 are easily fixed, and the firmness and reliability of the assembly can be improved.

[0044] In the above embodiment, the second limiting portion 13 is a buckle, which is arranged on the outer wall of the box body 10, and the buckle includes a straight edge section 131, an arc section 132 and a bent section 133, which are connected in sequence. The straight edge section 131 is fixedly connected to the box body 10, and the bent section 133 is a free end, and the bending direction of the bent section 133 is a direction away from the straight edge section 131. The electrical box of the present invention is configured to have a structure in which the straight edge section 131, the arc section 132 and the bent section 133 are connected in sequence, and the straight edge section 131 is fixedly connected to the box body 10, so that during assembly, the card slot is connected to the buckle, so that the buckle is elastically deformed, and the deformation elastic force of the buckle forms an interference fit with the card slot, so as to ensure that the assembly is firm and reliable, and no fasteners are required, and the assembly and disassembly are convenient. It can be understood that the width of the slot is larger than the width above the buckle, but slightly smaller than the maximum width of the buckle, so that an interference fit can be formed.

[0045] In the above embodiment, there are a plurality of first limiting portions 23, and the plurality of first limiting portions 23 are arranged at intervals on the box cover 20, which can improve reliability.

[0046] According to another aspect of the present invention, an air conditioner is disclosed, comprising the above-mentioned electrical appliance box.
