Description

An air conditioner electric control box

technical field

The utility model relates to the technical field of air conditioners, in particular to an air conditioner electric control box.

Background technique

With the promotion and application of inverter air conditioners in the market for many years, the maintenance service of inverter air conditioners has become an urgent problem for air conditioner manufacturers.

The split-type inverter air conditioner is divided into two parts: an indoor unit and an outdoor unit. Both the indoor unit and the outdoor unit are equipped with electric control boards, and the outdoor electric control board is the most important component with a high failure repair rate. This is because the working environment of the outdoor electric control board is harsh, and dust and moisture will enter the electric control board, causing poor heat dissipation, short circuit and subsequent failure of the electronic components. Therefore, how well the outdoor electric control box protects the electric control board largely determines the failure repair rate of the inverter air conditioner. The top of the electric control box of the existing outdoor electric control box structure is open, and it is easy to cause dust and moisture to enter the electric control panel from the top of the electric control box, thereby causing damage to the electronic components.

Therefore, it is necessary to provide an outdoor electric control box device with perfect protection for the electric control board.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide an air conditioner electric control box which effectively prevents impurities from entering, is easy to install, and has good heat dissipation.

The technical scheme adopted by the utility model is: an air conditioner electric control box, including a box body of the electric control box, and a box cover matching the size of the box body, the box body is provided with a plastic card, and the box cover is provided with a There are openings for respectively cooperating with plastic cards to fix the lid on the box body.

The plastic card is a plastic bar protruding laterally from the box body, the length of the plastic card is 10mm, the width is 5mm, and the thickness is 1.5mm.

Two plastic cards are respectively arranged on the front wall and the rear wall of the box body.

The holes are hollowed out on the cover sheet metal. The length of the holes is 10mm and the height is 1.5mm. The number of holes is the same as that of the plastic card, and the positions correspond to the positions of the plastic cards one by one.

The rear part of the side wall of the box body is provided with a heat dissipation port, and the heat dissipation port is composed of a plurality of rectangular hollows.

Compared with the prior art, the utility model has the following advantages:

1. By adding a box cover on the electric control box, it can prevent dust and water from entering the electric control board from above, and ensure the stable operation of the electric control board;

2. Use the cooperation of the plastic card and the opening to fix the box cover on the box body, which is easy to install and operate.

Detailed ways

The utility model will be further described below through specific embodiments in conjunction with the accompanying drawings.

An air conditioner electric control box of the utility model, as shown in Figure 1-6, includes a box body 1 and a box cover 2 of the electric control box, the box cover 2 matches the size of the box body 1, and can be covered on the box body 1 to Prevent impurities from entering the electric control box from above the electric control box.

For fixing the box cover 2 on the box body 1, two plastic cards are respectively arranged on the front wall and the back wall of the box body 1, the front plastic card 12 being arranged on the front wall, and the rear plastic card 11 being arranged on the back wall; The front wall of the cover is provided with a front opening 22 corresponding to the front plastic card 12, and the rear wall is provided with a rear opening 21 corresponding to the rear plastic card 11.

The front plastic card 12 and the rear plastic card 11 are plastic horizontal bars protruding laterally on the box body 1, with a length of 10 mm, a width of 5 mm, and a thickness of 1.5 mm.

The front opening 22 and the rear opening 21 are hollowed out on the sheet metal of the box cover 2, with a length of 10mm and a height of 1.5mm. The positions of each front opening 22 correspond to each front plastic card 12 one by one, and each rear opening The positions of the holes 21 correspond to the respective rear plastic cards 11 one by one.

The rear portion of the side wall of the box body 1 is provided with a cooling vent 13, which consists of fourteen vertical rectangular holes with a length of 48 mm and a width of 3 mm arranged horizontally. The heat dissipation port 13 is on the left side of the middle partition, close to the heat dissipation fan, and utilizes the airflow of the heat dissipation fan to dissipate heat for the electric control board.

The outer wall of the rear part of the bottom plate of the box body 1 is provided with a cooling fin 3, which dissipates heat for the electric control board through heat conduction with the electric control board and the airflow of the cooling fan.

The installation steps of an air conditioner electric control box of the utility model are as follows:

First, install the electric control board in the electric control box, and lead the electric wires out of the electric control board through the cable opening; then pick up the box cover 2, the rear part of the box cover 2 is moved down first, and the rear opening 21 is fastened to the rear plastic card 11; While the front part of the box cover 2 is moving down, keep the rear opening 21 interlocked with the rear plastic card 11, and pull the box cover 2 back with moderate force by hand, so that the sheet metal of the box cover 2 has a certain elastic deformation , the front edge of the box cover will not be stuck on the front edge of the box body 1; finally, until the front plastic card 12 is aligned with the front opening 22, the pulling force is removed at this time, the box cover 2 returns to its original shape, and the front opening 22 Buckle the front plastic card 12, and the installation is completed.
