Document Type and Number:
WIPO Patent Application WO/2017/000469
Kind Code:
A1
Abstract:
Disclosed is a bladeless fan with an air purification function. The bladeless fan comprises a flow guiding body (31). A main frame (32) is connected to the lower portion of the flow guiding body (31). A drainage air duct is formed at the joint between the flow guiding body (31) and the main frame (32). The main frame (32) comprises a heat pump device (1), a water collecting device (2), a controller (3) and a shell (4). The heat pump device (1) comprises a compressor (5), an evaporator (6), a heat radiator (7), an expansion valve (8) and a draught fan (9). The surface of the evaporator (6) and the surface of the heat radiator (7) are coated with a nano titanium dioxide coating. The water collecting device (2) comprises water collecting tanks (11). The collecting tanks (11) are provided with grooves (13) and bosses (14). Each boss (14) is hollow and provided with an ultraviolet lamp tube (12). Each boss (14) is provided with a ventilation hole (15). The shell (4) is provided with air outlets (16) and air inlets (17). The controller (3) is connected to the compressor (5) and the draught fan (9). During operation, the ultraviolet lamp tubes are turned on, and the nano titanium dioxide coating functions as a catalyst to remove hazardous substances, such as formaldehyde, in the air; meanwhile, the heat radiator and the evaporator are utilized for dehumidifying the air, and therefore the purposes of purifying and dehumidifying the air are achieved.
