A fan assembly includes a nozzle having a first casing section, a second casing section, an air inlet, an air outlet, and an interior passage for conveying air from the air inlet to the air outlet. The nozzle defines a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle. The nozzle is detachably mounted on a body including a motor and impeller unit for generating an air flow through the interior passage, and a humidifier for humidifying the air flow before it enters the interior passage. The first casing section defines, at least in part, the interior passage, and is detachable from the second casing section to allow the interior passage to be accessed by a user for cleaning.

Fan assembly

A humidifying apparatus includes a nozzle and a base on which the nozzle is mounted. The nozzle has respective first and second air inlets, air outlets and interior passages for conveying air therefrom and thereto. The nozzle defines a bore through which air outside the humidifying apparatus is drawn by air emitted from the air outlets. The base generates first and second air flows through the respective first and second interior passages, and a water reservoir. First and second air passageways convey the first and second air flows to the respective first and second air inlets. As the second air passageway conveys the second air flow over the water in the reservoir, water stored in the reservoir is agitated. An ultraviolet radiation generator irradiates the agitated water for a period of time before water stored in the reservoir is atomized to increase the humidity of the second air flow.

Humidifying apparatus

Humidifying apparatus includes one or more motor and impeller units for generating a first air flow and a second air flow. A nozzle has a first air outlet for emitting the first air flow, with the nozzle defining an opening through which air from outside the humidifying apparatus is drawn by air emitted from the first air outlet. The second air flow is humidified and emitted from a plurality of second air outlets. A body comprising a water tank for supplying water for humidifying the second air flow is configured to releasably retain the nozzle on the apparatus.

Humidifying apparatus includes a housing defining a water reservoir, and a water tank mounted on the housing for supplying water to the reservoir. An air flow is conveyed over water stored in the reservoir and emitted from the apparatus. The water stored in the reservoir is irradiated by ultraviolet radiation and atomized by a transducer to humidify the air flow passing over the reservoir. A flow of water entering the reservoir is guided adjacent to, and preferably along, the ultraviolet radiation generator.

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.

A fan assembly includes a body housing an impeller and motor for driving to the impeller to generate an air flow. A nozzle is mounted on the body for emitting the air flow. The nozzle defines an opening through which air from outside the fan assembly is drawn by the air emitted from the nozzle. A nozzle retaining mechanism is provided for releasably retaining the nozzle on the body. The mechanism is moveable from a first configuration in which the nozzle is retained on the body to a second configuration in which the nozzle is released for removal from the body. The mechanism includes a depressible member for effecting movement of the mechanism from the first configuration to the second configuration.

Humidifying apparatus includes a chamber, and a water tank for supplying water to the chamber. A baffle located within the chamber divides the chamber into an inlet section and an outlet section, and guides water received from the water tank along the inlet section to the outlet section. An air flow is conveyed over water stored in the outlet section of the chamber and is emitted from the apparatus. Water within both the inlet section and the outlet section of the chamber is irradiated with ultraviolet radiation. The water within the outlet section is atomized by a transducer to humidify the air flow.

Humidifying apparatus includes a base housing an impeller and a motor for driving the impeller to generate a first air flow. A nozzle includes an interior passage for receiving the first air flow and an air outlet for emitting the first air flow. The nozzle defines an opening through which air from outside the apparatus is drawn by air emitted from the air outlet. The apparatus is configured to humidify a second air flow, which is emitted from a plurality of second air outlets. The second air flow is humidified with water supplied from a water tank mounted on the base. The water tank has an upwardly curved upper surface. The nozzle is mounted on the apparatus so that the upper surface of the water tank at least partially covers a lower section of an external surface of the nozzle.

A humidifying apparatus includes a base, a water tank removably mounted on the base for supplying water to a chamber of the base, and a motor-driven impeller for generating an air flow over water stored in the chamber. An ultraviolet radiation emitting lamp irradiates water stored in the chamber. The air flow is humidified with water from the chamber, and conveyed by an outlet duct towards an air outlet for emission from the apparatus. A detachable section of the water tank is opaque to ultraviolet radiation and is positioned over the chamber when the water tank is mounted on the base. The detachable section of the water tank includes an air inlet of the outlet duct and a flange for occluding a peripheral portion of the chamber.

A fan assembly includes a nozzle having a plurality of air inlets, a plurality of air outlets, a first air flow path and a second air flow path. Each air flow path extends from at least one of the air inlets to at least one of the air outlets. The nozzle defines a bore through which air from outside the fan assembly is drawn by air emitted from the nozzle. The fan assembly also includes a first user-operable system for generating a first air flow along the first air flow path, and a second user-operable system, different from the first user-operable system, for generating a second air flow along the second air flow path. Through user selection of one or both of these two systems, at least one of two different air flows can be emitted from the nozzle, each having a respective flow profile or other characteristic.

Humidifying apparatus includes a base housing a motor and impeller unit for generating a first air flow. A nozzle includes an interior passage for receiving the first air flow and an air outlet for emitting the first air flow. The nozzle defines an opening through which air from outside the apparatus is drawn by air emitted from the air outlet. The apparatus is configured to humidify a second air flow, which is emitted from a plurality of second air outlets. The second air flow is humidified with water supplied from a water tank mounted on the base. The water tank surrounds at least an upper section of the motor and impeller unit.

A fan assembly includes a nozzle and a body on which the nozzle is mounted. The nozzle has a first air inlet, a first air outlet, and a first interior passage for conveying air from the first air inlet to the first air outlet. The nozzle also includes a second air inlet, a plurality of second air outlets, and a second interior passage for conveying air from the second air inlet to the second air outlets. The body generates a first air flow through the first interior passage and a second air flow through the second interior passage. A first air passageway conveys the first air flow to the first air inlet and a second air passageway conveys the second air flow to the second air inlet. One of the temperature, humidity, composition and electrical charge of the second air flow is changed before it is emitted from the nozzle.
