When the box cover 2 is closed on the box body 1, the bending wall can cover the connection between the box cover 2 and the box body 1, so as to improve the sealing performance of the electric control box, and at the same time When the box cover 2 is closed on the box body 1, it plays a guiding role, making the assembly smoother.

Specifically, as shown in FIGS. 8 to 11 , the bending wall includes a first bending wall 211 disposed on the top surface 21 and a second bending wall 221 disposed on the inclined cover plate 22 . A bending wall 211 is formed by bending the opposite side edges of the top surface 21 to the side close to the box body 1 , and the second bending wall 221 is formed by the opposite side edges of the inclined cover plate 22 . It is formed by bending to the side close to the box body 1 .

Further, the edge of the bending wall is bent to the side away from the box body 1 to form a flange. On the one hand, the flanging can make the assembly of the box cover 2 and the box body 1 faster, and the engagement is more accurate and firm; The water guide channel formed by the edge is directly drained to avoid the electrical components in the electric control box from being wetted.

Specifically, as shown in FIGS. 8 to 11 , the flange includes a first flange 212 located on the first bending wall 211 and a second flange 222 located on the second bending wall 221 . The first flange 212 is bent away from the box body 1 from the edge of the first bending wall 211 , and the second flange 222 is bent away from the edge of the second bending wall 221 The direction of the box body 1 is bent.

Further, as shown in FIGS. 8 to 16 , the flange further includes a third flange 213 located at the edge of the top surface 21 , and the third flange 213 moves away from the edge of the top surface 21 to the The direction of the box body 1 is bent. The third flange 213 is used for engaging with the engaging slot 121 to improve the stability of engaging.

As some embodiments of the present application, as shown in FIGS. 12 to 16 , the inclined cover plate 22 and the third flange 213 are arranged opposite to both sides of the top surface 21 , and the first bending wall 211 is arranged opposite to The other two sides of the top surface 21; the top surface 21 and the second connecting surface 23 are oppositely arranged on both sides of the inclined cover plate 22, and the second bending wall 221 is oppositely arranged on the inclined cover plate 22 the other sides of the . When the box cover 2 is assembled with the box body 1, it is only necessary to place the side of the second connecting surface 23 in the box cover 2 on the upper side of the box body 1, as shown in FIG. The first bending wall 211 is aligned with the two sides of the box body 1, and then pushes the box cover 2 downward, so that the box cover 2 slides along the box body 1 under the guiding action of the first bending wall 211 until After the third flange 213 is snapped into the snap groove 121, stop pushing the box cover 2, at this time, the second bending wall 221 will naturally cover the side notch of the electric control box and the inclined cover At the connection of the board 22, the second connection surface 23 will be stacked on the first connection surface 15, and the second connection hole 231 and the first connection hole 151 only need to be screwed through the second connection hole 231 and the first connection hole. The two connecting surfaces 23 and the first connecting surface 15 are fixed together to realize the assembly of the box body 1 and the box cover 2 . When the electric control box needs to be repaired, it is only necessary to remove the screws that fix the second connection surface 23 and the first connection surface 15 in the reverse order, and pull the box cover 2 upward until the box cover 2 is in contact with the box. The body 1 can be completely detached, the operation process is convenient and simple, and the electric control box can be disassembled and assembled repeatedly, and is not easily deformed.

In addition, a portion of the top surface 21 of the box cover 2 protrudes toward the outside of the electric control box to form a capacitor accommodating portion 214 , and the capacitor accommodating portion 214 is arranged corresponding to the capacitor in the electric control box, so that the electric control box can accommodate High-height capacitive components.

The present application also provides an air conditioner, which includes the above-mentioned electrical control box.

Preferably, the air conditioner is a pedestal crane, that is, an air conditioner capable of pedestal and ceiling installation.

To sum up, it can be concluded that the electric control box and the air conditioner of the present application have the advantages of simple and stable structure, good sealing performance, convenient disassembly and assembly, and are not easily deformed during repeated disassembly and assembly of the electric control box.
