A fan assembly for creating an air current is described, the fan assembly having a nozzle, a system for creating an air flow through the nozzle and a filter for removing particulates from the air flow, the nozzle having an interior passage, a mouth for receiving the air flow from the interior passage, and a Coanda surface located adjacent the mouth and over which the mouth is arranged to direct the air flow, wherein the fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan, i.e. air flow is created by a bladeless fan.

Fan with a filter

A fan assembly includes an annular nozzle and a system for creating a primary air flow. The nozzle includes an outer wall and an inner wall surrounded by the outer wall, the inner wall defining a bore having a bore axis. The nozzle also includes an interior passage located between the inner and outer walls, and extending about the bore axis for receiving an air flow, and an air outlet located at or towards the front of the nozzle for emitting the air flow. The nozzle is configured to emit the air flow through the air outlet in a direction extending away from the bore axis.

Fan assembly

Fan utilizing coanda surface

A bladeless fan assembly includes a nozzle mounted on a base housing a device creating an air flow through the nozzle. The nozzle includes an interior passage receiving the air flow from the base and a mouth through which the air flow is emitted. The nozzle extends substantially orthogonally about an axis to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The depth of the base in the direction of the axis may be no more than twice the depth of the nozzle. The assembly produces an air current without requiring a bladed fan, that is, the air flow is created by a bladeless fan.

An annular nozzle for a ceiling fan includes an inner wall defining a bore having a bore axis, an outer wall extending about the inner wall, an air inlet for receiving an air flow, and an air outlet section extending between the inner wall and the outer wall. The air outlet section defines an air outlet for emitting the air flow. An interior passage extends about the bore axis for conveying the air flow to the air outlet. The air outlet section is configured to emit the air flow away from the bore axis.

A fan assembly for creating an air current includes a bladeless fan assembly including a nozzle and a device for creating an air flow through the nozzle. The nozzle includes an interior passage and a mouth receiving the air flow from the interior passage. A Coanda surface located adjacent the mouth and over which the mouth is arranged to direct the air flow. The fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan, that is, the air flow is created by a bladeless fan.

A fan assembly for creating an air current includes a nozzle mounted on a base. The base comprises an outer casing, an impeller housing located within the outer casing, the impeller housing having an air inlet and an air outlet, an impeller located within the impeller housing and a motor for driving the impeller to create an air flow through the impeller housing. The nozzle includes an interior passage for receiving the air flow from the air outlet of the impeller housing and a mouth through which the air flow is emitted from the fan assembly.

A fan assembly for creating an air current includes a nozzle mounted on a base. The base includes an outer casing, a silencing member housed within the outer casing, an impeller housing located within the outer casing, the impeller housing having an air inlet and an air outlet, an impeller located within the impeller housing and a motor for driving the impeller about an axis to create an air flow through the impeller housing. The nozzle includes an interior passage for receiving the air flow from the air outlet of the impeller housing and a mouth through which the air flow is emitted from the fan assembly. The silencing member is located beneath the air inlet of the impeller housing and is spaced from the air inlet along said axis by a distance in the range from 5 to 60 mm.

A drying apparatus has a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and creating an airflow, and at least one slot-like opening communicating with the fan and arranged in the casing so as to direct an airflow transversely across the cavity. The slot-like opening has a maximum width which is no greater than 0.8 mm. This produces a very narrow, high velocity, high pressure airflow which is capable of drying an object efficiently and quickly and is suitable for use in a hand dryer.

Drying apparatus

A bladeless fan assembly for creating an air current includes a nozzle mounted on a base housing a device for creating an air flow through the nozzle. The nozzle includes an interior passage for receiving the air flow from the base and a mouth through which the air flow is emitted. The nozzle extends about an axis to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle includes a surface over which the mouth is arranged to direct the air flow. The surface has a diffuser portion tapering away from the axis, and a guide portion downstream from the diffuser portion and angled thereto.

A drying apparatus has a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and creating an airflow, a motor provided in the casing for driving the fan and ducting for carrying the airflow from the fan to at least one opening arranged to emit the airflow into the cavity, wherein the ducting includes at least one air duct in which at least one vane is located, the vane extending in the direction of airflow and dividing the air duct into a plurality of airflow portions.
