Of course, these structural designs can be adjusted according to the actual situation. Other compositions and connection relationships are the same as those of the first, second, third, fourth, fifth, sixth, seventh or eighth embodiments.
Principle of operation
The working principle of the active-running passive flow control natural flapping air supply device according to the invention is described with reference to fig. 1 to 11:
when the air conditioner is closed, all the parts are positioned on the original station, all the baffles on the front panel of the cabinet air conditioner can completely close the air outlet, the user can not see the internal parts of the air conditioner, and the whole air conditioner is attractive.
When the air conditioner is started, various baffles on the front panel of the cabinet air conditioner act, so that the air outlet is completely opened. The wind guide piece 1 and the ventilation net 2 are combined through the slideway 1d and the flange 2d, wherein the wind guide piece 1 is a fixed piece, the ventilation net 2 is a movable piece, the ventilation net 2 is driven by external force to slide up and down in a reciprocating manner, and the maximum sliding distance is one lattice length.
When the assembly of the air guide piece 1 and the air permeable net 2 is at the station, the servo motor 35 of the air permeable net driving mechanism 3 rotates positively, the air permeable net 2 slides to the uppermost side, and the wedge directions of all triangular wedges 2b of air outlet are all left. At this time, the right side opening area of the triangular wedge 2b is small, and the right side opening area of the triangular wedge is large, so that the right vortex flow can be formed after the wind coming from the cross flow fan passes through the assembly.
When the assembly of the air guide piece 1 and the air permeable net 2 is at the station two, the servo motor 35 of the air permeable net driving mechanism 3 is reversed, the air permeable net 2 slides to the lowest, and all the triangular wedges 2b of the air outlet are directed to the right. At this time, the right opening area of the triangular wedge 2b is small, and the left opening area is large, so that the left vortex flow can be formed after the wind coming from the cross flow fan passes through the assembly.
During the movement of the station one to the station two or the station two to the station one, the total air outlet area of the combined air guide 1 and air permeable net 2 is constant. Because the ventilation net 2 continuously acts relative to the air guide piece 1, stations of the assembly are also continuously changed, left-handed air and right-handed air flow alternately appear, the mechanical air supply has higher turbulence intensity, larger turbulence integral scale, more natural turbulence vortex and a sequencing structure by strengthening turbulence and enhancing convection heat exchange coefficient, and the air supply refrigerating effect is improved. In addition, according to the existing building environment theory, the cold feeling of people and the freshness feeling of air can be increased by a certain degree of turbulent air flow, and the effect of the design can be further improved.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
