Title:
AIR CONDITIONER INDOOR UNIT AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/202028
Kind Code:
A1
Abstract:
Provided are an air conditioner indoor unit (10) and an air conditioner, the air conditioner indoor unit (10) comprising a cross-flow fan (200) and an air supply volute (300), wherein the air supply volute (300) comprises a fan section (320) and an air duct section (330). The air supply volute (300) extends from the outer periphery of the cross-flow fan (200) to an air supply port (100) of the air conditioner indoor unit (10), and defines an air supply duct (310). The fan section (320) extends toward the air supply port (100) along the outer periphery of the cross-flow fan (200). The air duct section (330) has a first side pivotally arranged at an extension end (321) of the fan section (320), and a second side extending toward the air supply port (100), and is configured to rotate toward and away from the air supply duct (310), so as to change the width of the air supply duct (310). The air duct section (330) can rotate towards and away from the air supply duct (310), so as to change the width of the air supply duct (310). When the rotational speed of the cross-flow fan (200) is reduced, the air duct section (330) rotates toward the air supply duct (310), so that the width of the air supply duct (310) is reduced. Therefore, the backflow area in the air supply duct (310) can be forcibly eliminated, and noise generated by the air conditioner indoor unit (10) is prevented.
