Insect-resistant electronic control box

Abstract

The invention discloses an insect-resistant electronic control box, comprising an electronic control box body and a sealing cover board. The sealing cover board is set on the electronic control box body. The sealing cover board is rotationally connected in the electronic control box body. A heat dissipation device is set on the front of the electronic control box body. The heat dissipation deviceis embedded into the electronic control box body. Protection grids are set on the heat dissipation device. The protection grids are fixedly connected with the heat dissipation device through bolts. Wire holes are set at left and right sides of the electronic control box body. The wire holes are in penetration connection in the electronic control box body. Sealing rubber rings are set in the wire holes. The sealing rubber rings are fixedly connected with the wire holes. In order to prevent an electronic control device from being damaged by staying of an insect, an ultrasonic insect expelling device is set on the electronic control device, cry of a natural enemy of the insect is simulated through utilization of ultrasonic, so the insect is expelled, and the defect that the insect is liable to be attracted by heat generated through the electric control device and stays on the device due to the fact that a traditional device has no insect expelling device is solved.

Description

technical field [0001] The invention relates to the technical field of electric control equipment, in particular to an insect-proof electric control box. Background technique [0002] In the field of air conditioning, the electric control box is a commonly used device. Generally, its structure includes a box base, a box body placed on the box base, a main control board on the box body, and an electric control box that covers the main control board. The cover plate, the box base has an accommodation space for the components of the main control board and an opening connecting the accommodation space and the outside of the box base, and the box body is provided with a wiring groove communicating with the accommodation space, Because of the above-mentioned structure, insects can easily enter the wiring trough through the accommodation space, bite the wires in the wiring trough, and even enter the wiring area on the main control board, causing a short circuit on the main control ...

[0002] In the field of air conditioning, the electric control box is a commonly used device. Generally, its structure includes a box base, a box body placed on the box base, a main control board on the box body, and an electric control box that covers the main control board. The cover plate, the box base has an accommodation space for the components of the main control board and an opening connecting the accommodation space and the outside of the box base, and the box body is provided with a wiring groove communicating with the accommodation space, Because of the above-mentioned structure, insects can easily enter the wiring trough through the accommodation space, bite the wires in the wiring trough, and even enter the wiring area on the main control board, causing a short circuit on the main control board.

[0003] However, due to the airtightness of the existing wire slots and wire inlet holes, insects enter the electric control box through the above-mentioned gaps and damage the wires, and even cause a short circuit on the circuit board, which affects the work of the electric control box. There is no effective way to drive or kill the insects in the box, so they can only be cleaned manually, which makes the cleaning work cumbersome and difficult to clean
