Abstract

The embodiment of the invention provides a cross-flow fan and an air conditioner. The cross-flow fan comprises at least two supporting discs arranged in a spaced manner, wherein one supporting disc isrotationally and coaxially connected with a steering gear; and a plurality of moving fan blades are mounted on the supporting discs at intervals in the circumferential direction in a swinging manner,and the plurality of moving fan blades are connected to the steering gear so as to swing relative to the supporting discs along with rotation of the steering gear. According to the cross-flow fan, anexisting fixed fan blade structure is improved, the air outlet angle of the fan blades can be adjusted in real time according to the air volume requirement, power waste of a main motor for adjustingthe rotating speed is reduced, and noise caused by the too large rotating speed is prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a cross-flow fan and an air conditioner. Background technique [0002] Air conditioners are household devices commonly used in our daily life, which can adjust parameters such as temperature, humidity, cleanliness, and air velocity of the air in a room (or closed space, area) to meet the requirements of human comfort or technological process. At present, the cross-flow fans of air-conditioning indoor units are widely used in air-conditioning equipment and small air-supply equipment due to their excellent characteristics such as large flow rate, low noise, and stable air supply. The impeller of the cross-flow fan is multi-blade, long cylindrical, with fixed forward multi-wing blades. During the working process of the air conditioner, one end of the cross-flow fan is rotatably installed on the casing, while the other end is driven by the main motor to rotate. The change o...
