Cross-flow fan for air conditioner

Abstract

The invention provides a cross-flow fan for an air conditioner, and relates to the technical field of air conditioner parts. The cross-flow fan comprises a fixing frame, a fan assembly and a cleaningmechanism, wherein an impeller is fixedly connected to the other end, far away from a servo motor, of a rotating shaft, a front flow guide plate is welded to the right side of an inner cavity of the fixing frame, a rear flow guide plate is welded to one side, far away from the front flow guide plate, of the inner cavity of the fixing frame, an air outlet is formed in the front side of the fixing frame, and a movable door is hinged to the output end of the air outlet. According to the cross-flow fan, the position of a movable plate is adjusted by utilizing a telescopic rod, so that the movableplate is located on the two sides of a set of blades on the impeller, a screw rod is driven to rotate through a driving piece, so that a transverse plate moves up and down along the screw rod, the impeller in a standing state is cleaned through a cleaning brush, dust is removed, and the dust falls into a dust discharging hopper; and an electromagnet is matched with a cover plate, so that the dustdischarging hopper can be closed, dust raising caused by the fan assembly during working is prevented, and the whole device is more reasonable.

Description

technical field [0001] The invention relates to the technical field of air-conditioning components, in particular to a cross-flow fan for air-conditioning. Background technique [0002] An air conditioner is an air conditioner, which regulates temperature and humidity. It is a unit used to provide a space area (generally closed) to deal with air temperature changes. Its function is to control the temperature of the air in the room (or closed space, area) , humidity, cleanliness and air flow rate and other parameters are adjusted to meet the requirements of human comfort or process; [0003] Tubular flow fans, also known as cross flow fans, are generally used in occasions with low speed and large conveying diameter, suitable for conveying cold or hot air in air conditioners; [0004] However, the function of the existing perfusion fans for air conditioners is relatively single, and if the air conditioner is not suitable for a long time, a lot of dust will remain inside the f...
