Description
Technical Field
The invention relates to the field of air conditioners, in particular to an electric control box and an air conditioner with the same.
Background
In the prior art, an electric control box is generally required to be configured to control the operation of each electric component, and the electric control box has high requirements on fire prevention and heat dissipation performance because of the relation to the normal operation of the air conditioner.
The applicant carries out intensive research on the electric control box of the air conditioner in the prior art, finds that the electric control box of the air conditioner needs to be overhauled through a detachable box cover, a circuit board in the electric control box comprises a large number of electric elements, heat emitted during operation and fire in the electric control box can be caused when faults occur, in order to achieve the purpose of fire prevention, a part of metal fireproof plates are usually arranged in the electric control box, the supporting plates need to be stably grounded in view of the problem that the electric leakage and the like are harmful to human health, the box cover of the electric control box is not easy to be provided with a stable grounding structure due to the detachable characteristic, therefore, in the electric control box of the air conditioner, the box cover is often of a plastic structure, the fire prevention performance of the whole electric control box is influenced, and also finds that part of researchers arrange the metal plates on the box cover to improve the fire prevention performance, the grounding is often completed, however, since the lid is a maintenance member, the metal plate is likely to come into contact with the case body and loose due to multiple opening and closing operations, which is likely to cause poor grounding, thereby causing electric shock.
Accordingly, the present invention is directed to a method for manufacturing a semiconductor device.
Disclosure of Invention
The invention solves the problem that in the prior art, the box cover is of a plastic structure and has poor fireproof performance, or a metal plate is arranged on the box cover, so that poor grounding is easily generated after the box cover is opened and closed for many times.
In order to solve the problems, the invention provides an electric control box and an air conditioner with the same, wherein a box cover of the electric control box comprises a plastic box cover and a metal box cover, the metal box cover is fixedly arranged at one side of the plastic box cover close to a box body so as to ensure that the box cover of the electric control box has good fireproof performance, a support plate is arranged at the bottom of a wiring board in consideration of the grounding condition of the metal box cover, the support plate is made of metal and is stably grounded, a bulge is arranged on the support plate, the top of the bulge is abutted against the metal box cover and then fixed in a screw fixing mode, connecting holes are respectively arranged on the plastic box cover and the metal box cover, the connecting holes arranged on the plastic box cover are larger than screw caps of screws for fastening, therefore, when the electric control box is fastened, the screw caps are directly pressed on the metal box cover and fastened, and the arrangement, thereby the metal box cover is stably grounded.
The invention discloses an electric control box which comprises a box body and a box cover, wherein the box cover is detachably covered on an opening of the box body, the box cover comprises a plastic box cover and a metal box cover, the metal box cover is arranged at one side close to the box body, the metal box cover is used for improving the fireproof performance of the box cover, a supporting plate is arranged in the opening of the box body, the supporting plate is abutted against the metal box cover, and the supporting plate is used for fixing and grounding the metal box cover.
Increase on the lid and set up the metal lid, the metal lid can effectual promotion the fire behavior of lid, will simultaneously the metal lid sets up in the one side that is close to the box body, is favorable to realizing through other structures the ground connection of metal lid has avoided setting up the metal lid when keeping away from automatically controlled box one side, and frequent lid is opened and is taken place the bad condition of ground connection easily under the condition set up the backup pad in the opening of box body, it is concrete, the backup pad is the metal material, just the backup pad is reliably grounded, being provided with of backup pad does benefit to the ground connection setting of metal lid.
Furthermore, a positioning part is arranged on the plastic box cover, a limiting part is arranged on the metal box cover, and the metal box cover and the plastic box cover are fixedly connected through the matching of the positioning part and the limiting part.
Metal lid and plastics lid fixed connection are favorable to the stable in structure of upper cover makes things convenient for it to open, and is specific, spacing portion and location portion are provided with one or more respectively, and both set up in pairs, fixed connection mode can be the joint, connect or peg graft etc. arbitrary with both fixed connection's mode soon, the position of spacing portion and location portion can be exchanged.
Furthermore, location portion is the card post, spacing portion is the card hole, the card post is inserted and is accomplished fixedly in the card hole.
Specifically, the card post can be provided with the inclined plane in order to guide the installation of metal lid, will during the installation metal lid to the plastics lid impels, metal lid or card post produce elastic deformation when the contact, will the metal lid lasts to the plastics lid impels, until the card post inserts the card hole, and elastic deformation restores this moment, the metal box lid is fixed on the plastics lid, this fixed method can be comparatively simply with the metal lid is fixed on the plastics lid, is favorable to its quick production assembly.
Further, be provided with the bellying in the backup pad when the lid closes on the box body, the bellying with the lid butt.
Set up the bellying in the backup pad, the bellying with the lid butt because the lid is close to box body one side is the metal lid, can ensure bellying and metal lid butt, the face-to-face contact is favorable to the reliable ground connection of metal lid.
Further, a lower concave portion is arranged on the box cover, the lower concave portion is concave towards the direction of the box body, and when the box cover is closed on the box body, the convex portion is abutted to the inner side face of the lower concave portion.
Because the box lid with screw or bolt with when the box body is connected, the connecting piece has partly to expose on the connection surface, the concave part can hide exposed part on the one hand, prevents that exposed part from influencing the assembly of other parts in the air conditioner, and on the other hand, the setting of concave part can confirm fast the direction of installation of lid saves the assemble duration, and simultaneously, the setting of concave part down can also reduce the height of bellying is favorable to the peripheral wiring operation of bellying in the automatically controlled box.
Further, the lower concave part is provided with a connecting hole, the connecting hole penetrates through the plastic box cover and the metal box cover, a third connecting hole is formed in the protruding part, and the connecting hole and the third connecting hole are correspondingly arranged, so that the box cover is fixedly connected with the box body.
