Description

Hanging type cross-flow fan with simple heating function Technical Field The invention relates to the technical field of cross-flow fans, in particular to a hanging type cross-flow fan with a simple heating function. Background The cross-flow fan mainly comprises an impeller, an air duct and a motor. The impeller material is typically an aluminum alloy or engineering plastic. The aluminum alloy impeller has high strength, light weight and high temperature resistance, can keep long-term stable operation without deformation, is formed by injection molding of a mold and ultrasonic welding, and is generally used for occasions with lower rotating speed and larger diameter. The air duct is generally formed by stamping a metal sheet, and can also be cast by plastic or aluminum alloy. The shell adopts streamline design, so that the loss of air flow can be effectively reduced, and the working efficiency of the fan is greatly improved. The motor is a power part of the cross-flow fan and can supply power in an alternating current mode or in a direct current mode. The AC power supply mainly comprises a shaded pole motor and a capacitor starting motor, and the DC power supply is a DC brushless motor. The drive motor is generally flexibly mounted with the impeller and is fixed on the air duct. In order to meet the requirement of a heating function, the cross-flow fan in the prior art needs to be externally connected with independent warm air equipment or a complex heating module and an air duct, so that the cross-flow fan is large in structure, the contact time and area of air flow and a heating element are short, and heat transfer is insufficient. Therefore, it is necessary to solve the above problems by providing a cross-flow fan with a simple heating function.
