Fan coil return air purifying device and air conditioner

Abstract

The invention discloses a fan coil return air purifying device and an air conditioner. The fan coil return air purifying device comprises a groove-shaped shell which is formed by sequentially connecting a first side plate, a bottom plate and a second side plate, an electric control box and a purifying box. An electric control box body of the electric control box is installed on the opening side of the groove-shaped shell, and an electric control box cover of the electric control box is rotational fixed to the two side plates on the opening side of the electric control box body. An electric appliance box is installed on the inner side of the electric control box cover. Two microswitches are installed in the electric appliance box and are connected with a firing line and a null line of a power source correspondingly. Switch keys of the two microswitches extend out of a box body of the electric appliance box in the direction perpendicular to the electric control box cover. The purifying box is installed in the space, between the electric control box body and the bottom plate, of the groove-shaped shell, an initial-effect filtering net of the purifying box is pressed on the switch keys of the two microswitches in a covering manner after being installed, and therefore the two microswitches communicate with the firing line and the zero line correspondingly for supplying power; and the switch keys are bounced off to thoroughly cut off power supply after the initial-effect filtering net is demounted; and the potential safety hazards existing in the demounting and mounting process of a fan coil air opening purifier are avoided.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a fan coil return air purification device and an air conditioner. Background technique [0002] The purifier is installed at the air return port of the fan coil unit of the air conditioner, which can be applied to indoor air purification. [0003] In the prior art, when a purifier is installed at the air return port of the fan coil unit, its electric control box is generally installed on the upper part of the purifier and can be removed separately; a control circuit is installed in the electric control box, and the control circuit is connected to an external power supply; When the control box is disassembled, the control circuit is still connected to the external power supply, which poses a potential safety hazard of electric shock. Contents of the invention [0004] The application provides a fan coil return air purification device and an air conditioner,...
