Usually, the indoor unit is provided with a circuit board for integrating electronic control components. In order to protect the circuit board from being eroded or collided by water vapor, an electric control box is generally used to wrap the circuit board for protection. At the same time, in order to ensure the electrical insulation between the circuit board and the electric control box, the electric control box is generally made of plastic material. However, the fire resistance of the plastic electric control box is poor. When the circuit board causes an open flame due to a short circuit, the plastic electric control box The control box will be burned and deformed by an open flame. At the same time, the flame will spread from the plastic electric control box to the interior of the indoor unit, burning other components of the indoor unit, and even causing a fire.

In order to improve the fire resistance of the electric control box, the shell can be used to wrap the electric control box to achieve the purpose of fire prevention. The shell has strong fire resistance to prevent the flame from spreading further. However, since the circuit board needs to be connected to other components of the indoor unit through wires, the housing needs to be provided with multiple outlets for the wires to pass through. After the circuit board catches fire, the flame will easily escape from the outlets, thereby reducing the fire resistance of the housing. effect.
