Abstract

The invention provides an air mixer comprising a box. The box is provided with a first air inlet, a second air inlet and an air outlet communicated with one another. The first air inlet and the second air inlet are arranged in the sidewalls of the box, respectively. A baffle in a cambered shape and a rotating shaft fixedly connected with the baffle are disposed within the box. The cross section of the baffle is arc shaped. The height direction of the baffle is parallel to the rotating shaft. The baffle matches with one, having a larger opening, of the first air inlet and the second air inlet. force of incoming air upon the baffle can be decomposed into a first part perpendicular to the radial direction of the baffle and a second part parallel to the radial direction; the first part perpendicular to the radial direction can be partially counteracted; thus, the force of the incoming air upon the baffle is decreased, the torque of the incoming air upon the baffle is also decreased. Therefore, the baffle is fixed to a certain position, output torque which a drive mechanism needs to provide is lower, and energy consumption is lowered.

Description

technical field [0001] The invention relates to the field of ventilation, in particular to an air mixing device. Background technique [0002] In the field of ventilation, an air mixing device installed in the air channel is usually used to mix two kinds of air with different temperature, humidity or other parameters and transmit it to the designated space. [0003] See figure 1 , The air mixing device has a first air inlet 1 , a second air inlet 2 and an air outlet 3 . The wind deflector 4 of the existing wind mixing device is usually a flat plate structure, and the driving mechanism arranged at one end of the wind deflector 4 drives the wind deflector 4 to turn over, thereby changing the opening degree of the first air inlet 1 and the second air inlet 2 , so that the air discharged from the air outlet 3 is the mixed air entering from the first air inlet 1 and the second air inlet 2 . [0004] However, in the existing wind mixing device, since the wind at the air inlet h...
