Title:
AIR DUCT ASSEMBLY, WIND WHEEL APPARATUS, AND AIR-BLOWING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/017142
Kind Code:
A1
Abstract:
Disclosed are an air duct assembly (1000), a wind wheel apparatus comprising the air duct assembly (1000), and an air-blowing device. The air duct assembly (1000) comprises a shell (1), a heating body unit (2), and a driving mechanism (3), wherein an air duct (1a) is formed in the shell (1), the heating body unit (2) is arranged in the air duct (1a), and the driving mechanism (3) is connected to the heating body unit (2) so as to drive the heating body unit (2) to rotate in the air duct (1a). When cold air or normal-temperature air needs to be blown, the driving mechanism (3) drives the heating body unit (2) to rotate to a position where same avoids the air duct (1a), an airflow discharged from the air duct (1a) substantially does not pass through the heating body unit (2), the heating body unit (2) does not cause wind resistance to the airflow, and the air volume of a fan is relatively large; when the heating body unit (2) rotates to a position where same blocks the air duct (1a), the airflow discharged from the air duct (1a) flows through the heating body unit (2), such that the airflow blown by the fan is a hot airflow; and cold/hot airflow switching can be achieved by the driving mechanism (3) driving the heating body unit (2) to rotate, and the structure is simple and compact.
