Abstract
The invention relates to an air blower apparatus, in particular a jet air hand dryer, comprising: a housing having an inlet and an outlet, at least one air duct extending inside the housing between the inlet and the outlet, for guiding an air stream, a fan unit for producing a directed stream of air in the air duct, and a UV treatment unit arranged inside a section of the air duct, said UV treatment unit having a treatment chamber for at least parts of the stream passing through the air duct, characterised in that the treatment chamber is at least part of a receiving chamber for a fan impeller in the fan unit, wherein a plurality of lighting adapted to emit UV light are arranged inside the receiving chamber.
Claims20
An air blower apparatus comprising:
- a housing having an inlet and an outlet;
- at least one air duct extending inside the housing between the inlet and the outlet and configured to guide an air stream;
- a fan unit having a fan impeller configured to produce the air steam in the air duct;
- and
- a UV treatment unit arranged inside a section of the air duct, the UV treatment unit having a treatment chamber for at least parts of the air stream passing through the air duct;
- wherein
- the treatment chamber is at least part of a receiving chamber for the fan impeller in the fan unit, and a plurality of lights adapted to emit UV light are arranged inside the receiving chamber.
A method of disinfecting an air stream passing through an air handling system, the method comprising:
- driving a fan impeller to create an air stream and simultaneously actuating a UV light to emit UV light for disinfecting the air stream flowing through an air duct;
- and
- actuating a heating device to heat the air stream simultaneously with the driving of the fan impeller and the actuating of the light.
A jet air hand dryer comprising:
- a housing having an inlet and an outlet interconnected by an air duct;
- a fan unit disposed in a receiving chamber of the housing and including an impeller configured to circulate an air stream through the air duct and out the outlet to dry a person's hands;
- and
- UV lighting arranged along a section of the air duct such that the UV lighting emits UV light onto the impeller and the air stream to sanitize the impeller and air stream.
