Abstract

The invention relates to a tubular wind wheel capable of being used for air conditioner and fan products such as a split-type air conditioner indoor unit, a movable air conditioner, an air freshener, a dehumidifier, a low static pressure blast pipe machine, a tower fan, a window type air conditioner and so on. The tubular wind wheel comprises a rotating shaft (27) and blades which are arranged on the rotating shaft (27), and is characterized in that the blades which are arranged on the rotating shaft (27) comprise large blades (24) and small blades (26); the diameters of the large blades (24) and the small blades (26) are unequal, and the large-diameter blades (24) and the small-diameter blades (26) are distributed in the staggered form; and the mounting intervals along the circumferential direction between the large blades (24) and the small blades (26) are unequal intervals. The tubular wind wheel has the advantages of good sound quality, low noise, large air quantity, high production efficiency, easy change of the shape of the blades and the length of the wind wheel, high reliability and so on.

Description

technical field [0001] The invention relates to a cross-flow wind wheel used in air-conditioning and fan products such as indoor units of split-type air conditioners, mobile air conditioners, air fresheners, dehumidifiers, low static pressure duct machines, summer fans, window air conditioners, etc. Transformation technology of cross-flow wind wheel. Background technique [0002] The existing cross-flow fan wheel assembled into the air conditioner is as follows: Figure 10 As shown, on the front 2a of the casing 2 of the indoor unit 1, a suction grill 3 and a discharge grill 4 are arranged up and down in the figure, and these suction grills 3 and discharge grills are connected through the ventilation passage 6 in the fan casing 5. Grid 4 is connected. [0003] Moreover, a cross-flow impeller 21 as an indoor fan is provided on the leeward side of the indoor heat exchanger 7 of the ventilation passage 6, so that the indoor air sucked into the casing 2 from the suction grill 3...
