Abstract

The invention provides an air outlet device, a fan and a control method of the fan. The air outlet device comprises an air duct shell and a blade assembly, wherein the air duct shell is provided with an air inlet, an air outlet channel communicated with the air inlet and an air outlet communicated with the air outlet channel; and the blade assembly is located in the air duct shell and comprises a supporting rod and a blade arranged on the supporting rod, the blade comprises two blade sections and a connecting part connected with the two blade sections, and the connecting part is rotatably arranged on the supporting rod. According to the technical scheme, the problem that in the prior art, the air outlet device is not smooth in air outlet, and consequently noise is large is solved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to an air outlet device, a fan and a control method for the fan. Background technique [0002] In the prior art, the arc section of the blade of the air outlet device has a certain flow guiding effect, but the blade only includes the arc section and the connecting part, and the connecting part is connected with the support rod. In this way, the air flow field in the air outlet channel From bottom to top, the airflow will flow through the blades. When the airflow passes through the connecting part of the blades, the direction of the airflow will change suddenly by nearly 90 degrees. noise. Contents of the invention [0003] The main purpose of the present invention is to provide an air outlet device, a fan and a control method for the fan, so as to solve the problem of high noise caused by unsmooth air outlet in the air outlet device in the prior art.
