The utility model provides an automatically controlled box subassembly can be used to in air conditioner or other domestic electric appliances.

In the embodiment of the present invention, as shown in fig. 1 to 4, fig. 6, fig. 8 to 9, and fig. 12 to 13, the electronic control box assembly includes a box body 100, an electronic control component 200, a connection terminal 300, an electronic control box cover 400, a fire-proof cover 500, and a fire-proof cover 600. The box body 100 defines a mounting cavity 110 therein which is open at one end. The electronic control component 200 is mounted on one side of the mounting cavity 110. The connection terminal 300 is mounted to the other side of the mounting cavity 110. The electrical lid 400 is movably or detachably mounted to the box body 100 to cover the opening of the mounting cavity 110. The fireproof cover 500 is at least covered on the periphery of the box 100 corresponding to the electronic control component 200. The fireproof cover 600 is covered on the outer side of the electric control box cover 400, and the fireproof cover 600 is connected with the fireproof cover 500 in a buckling mode.

In this embodiment, the box 100 may be a rectangular parallelepiped or a square. The electronic control component 200 includes an electronic control main board and the like. The connection terminal 300 is used for external connection, such as connection to a ground line. The opening of the case 100 may be upward, front, rear, left, right, etc. The directions of up, down, front, back and the like refer to that the electric control box faces the user and is front, and the left side of the user is left after being installed. The specific orientation of the opening can be selected according to the use requirement, and is not particularly limited herein. The electric control box cover 400 can be movably mounted on the box body 100 by means of hinge, sliding groove and sliding rail connection, etc. The electrical box cover 400 can be detachably mounted on the box body 100 by means of a snap, a screw connection, or the like, that is, the electrical box cover 400 can open or close the opening of the mounting cavity 110. The electrical box cover 400 can cover the opening of the mounting cavity 110 when the electrical box cover 400 is closed, and the mounting cavity 110 can be exposed when the electrical box cover 400 is opened.

It is understood that the fireproof cover 600 and the fireproof cover 500 may be made of metal material such as sheet metal parts with fireproof function. The case body 100 and the electrical control case cover 400 may be made of plastic or other materials with good insulation property. The box body 100 and the electric control box cover 400 are preferably made of flame retardant materials, such as flame retardant abs (acrylonitrile butadiene styrene); the material has good heat resistance and flame retardant property, so that the box body 100 and the electric control box are prevented from burning when components inside the electric control box are on fire, and the fire behavior is further expanded. The box body 100 and the electric control box cover 400 are preferably made of bulk molding compound (bmc), which has high temperature resistance, good rigidity, and small shrinkage after thermal molding, so that the dimensional stability is good, and the mechanical properties can be ensured in a high-temperature environment.

The fireproof cover 600 is covered on the outer side of the electric control box cover 400 to play a fireproof role for the electric control box cover 400. The electric control component 200 and the wiring terminal 300 are disposed on two sides of the mounting cavity 110. In one embodiment, the fire-proof cover 500 covers the outer circumference of the box 100. At this time, the fireproof cover 600 and the fireproof cover 500 entirely surround the electric control box cover 400 and the box body 100, and the overall mandatory fireproof requirement can be met. In another embodiment, the fire-proof cover 500 may also only wrap the box 100 at a position corresponding to the position where the electronic control component 200 is disposed. The fireproof cover 600 can completely cover the junction terminal 300 to prevent fire from escaping from one side of the fireproof cover 600. Although the bottom fireproof cover 500 does not cover the connection terminal 300, since the position of the box 100 where the connection terminal 300 is installed is generally adjacent to the heat exchanger, the heat exchanger is also a metal member, and therefore, even if the connection terminal 300 burns, other parts in the air conditioner are not affected. As such, a terminal opening may be provided at the case 100 corresponding to the terminal 300, thereby facilitating external wiring. It will be appreciated that the fire shield 500 is snap-fit to the fire cover 600, meaning that the two are snap-fit by their own structure. The connection between the two can completely cover the box body 100 and the electric control box cover 400, thereby realizing fireproof sealing.

The utility model discloses automatically controlled box subassembly is through installing automatically controlled components and parts 200 and binding post 300 in box body 100, but automatically controlled lid 400 can dismantle or swing joint with box body 100, and the fire prevention cover 500 is established to the peripheral cover that corresponds automatically controlled components and parts 200 at box body 100, establishes fire prevention cover 500 at the outside lid of automatically controlled lid 400, and fire prevention cover 600 is connected with fire prevention cover 500 buckle. When operations such as need wiring, installation, maintenance, only need to make the fire prevention lid 600 break away from with fire prevention cover 500 buckle, then open the opening of installation cavity 110 with fire prevention lid 600 along with automatically controlled lid 400 together, alright operate automatically controlled components and parts 200 and binding post 300 etc. in the installation cavity 110, easy dismounting is swift, reduce the operation degree of difficulty, improved the operating efficiency. Simultaneously, because fire prevention lid 600 is connected through its fire prevention buckle of itself with fire prevention cover 500, compare in the plastic sealing connection of automatically controlled lid 400 with box body 100, small flame from the plastic connection department drunkenness out when can preventing that automatically controlled box from catching a fire to further improve the holistic fire prevention effect of automatically controlled box subassembly, avoid the inside part that catches a fire of automatically controlled box to influence other parts, cause the unnecessary loss.

Specifically, referring to fig. 1 to 4, 8 to 9, and 12 to 13 again, the fire-proof cover 500 has a first side 510 and a second side 520 opposite to each other, and the first side 510 and/or the second side 520 are connected to the fire-proof cover 600 by a snap-fit connection. The fire-proof cover 500 is substantially shaped like a box with an open upper end. The two sides of the fire-proof cover 500 may be the front side and the back side of the opening of the fire-proof cover 500, or the left side and the right side of the opening. So that the fire-proof cover 500 can wrap at least the bottom and two opposite sides of the box body 100. Through first side 510 and/or second side 520 with fire prevention cover 500 and fire prevention lid 600 buckle connection for edge between them is connected, simple structure, the installation of being convenient for, improves installation reliability and stability.
