Title:
CROSS-FLOW FAN, AIR CONDITIONER INDOOR UNIT, AIR CONDITIONER, AND AIR PORT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/114712
Kind Code:
A1
Abstract:
A cross-flow fan, an air conditioner indoor unit with same, an air conditioner, and an air port control method. The cross-flow fan comprises: a volute (5), a volute tongue (6), a supporting member (10) and a cross-flow wind wheel (7), wherein a cross-flow air duct is formed between the volute tongue (6) and the supporting member (10), an auxiliary air inlet (11) is further provided between the supporting member (10) and the volute (5), a first air deflector (8) is movably connected to the auxiliary air inlet (11), and the first air deflector (8) makes a reciprocal movement on the volute (5) so as to open or close the auxiliary air inlet (11). When the cross-flow air duct of the cross-flow fan is in communication with the air inlet of the air conditioner indoor unit, the auxiliary air inlet (11) is additionally arranged on the basis of an original air duct, the air inlet area of the air inlet of the air conditioner indoor unit is effectively increased, and the heat exchange efficiency of the air conditioner is improved; and when the cross-flow air duct is in communication with the air outlet, the arc-shaped cross-flow air duct composed of the volute tongue (6) and the supporting member (10) is formed, the air supply distance of the air conditioner indoor unit can be effectively increased, and the air supply capacity is improved.
