Abstract

A fan assembly includes a nozzle and a body on which the nozzle is mounted. The nozzle has a rear section having at least one first air inlet, at least one first air outlet, and a first interior passage for conveying air from the at least one first air inlet to the at least one first air outlet; and a front section having at least one second air inlet, at least one second air outlet, and a second interior passage for conveying air from the at least one second air inlet to the at least one second air outlet. A first air flow through the first interior passage and a second air flow through the second interior passage are each generated within the body. At least one of the temperature, humidity, and electrical charge of the second air flow is changed before it enters the second interior passage.

Claims14

Dependent claims

A humidifying apparatus comprising:

a nozzle having at least one first air inlet, at least one first air outlet, a first interior passage for conveying air from said at least one first air inlet to said at least one first air outlet, at least one second air inlet, at least one second air outlet, and a second interior passage for conveying air from said at least one second air inlet to said at least one second air outlet, the nozzle defining a bore through which air from outside the humidifying apparatus is drawn by air emitted from the nozzle;
and
a body on which the nozzle is mounted, the body comprising an air flow generator that generates a first air flow through the first interior passage and a second air flow through the second interior passage, a first air passageway for conveying the first air flow to said at least one first air inlet of the nozzle, a second air passageway for conveying the second air flow to said at least one second air inlet of the nozzle, and a humidifier that humidifies the second air flow before it enters the second interior passage.

Dependencies are inferred from the claim text.
