Air conditioner

Abstract

The application discloses an air conditioner, and belongs to the technical field of air conditioners. The air conditioner comprises a casing, a heat exchanger, a fan and an electric control box. The heat exchanger, the fan and the electric control box are arranged in the casing respectively. The electric control box comprises a box body, a base, an electric control board and a fastener. The box body is made of metal material, and the box body is connected to a ground wire. The base is arranged in the box body. The electric control board is arranged in the box body and is mounted on the base. The fastener is made of metal material, and the fastener is connected to the box body through the electric control board and the base, so that electric charges on the electric control board are transmitted to the ground wire through the box body. The fastener is not directly connected to the ground wire. The air conditioner provided by the application connects the box body of the electric control box to the ground wire, and connects the electric control board to the box body through a metal fastener, so that the electric control board is indirectly connected to the ground wire through the box body, thereby simplifying the grounding mode of the electric control board and saving the connection wire harness of the electric control board and the ground wire.
