When the wind wheel 102 rotates, a volute is formed inside the cross-flow wind wheel 102. The front volute tongue 108 and the rear volute tongue 109 are the dividing points, the upper half of which is the suction area, and the lower half is the discharge area, which is collected through the air duct 105. For diffuser blowing out, due to the consistency of the fluid at the outlet, the direction of the wind is changed by changing the angle of the horizontal or vertical guide vanes 106, 107, and the guiding effect is limited; at the same time, the guide vanes 106, 107 are used to change the wind direction. The air guide vanes themselves also produce a large wind resistance in the air duct 105, and because the air guide vanes 106, 107 are used to forcibly change the flow field, it is easy to generate a temperature difference on both sides of the air guide vanes 106, 107 and thus generate condensation. Since the air outlet 104 is elongated, the air outlet is dispersed, which is not conducive to centralized air supply. Thereby affecting the comfort of the room being adjusted.
