Embodiment Construction

[0034] figure 1 and 2 An embodiment of a bladeless fan assembly is shown. In this embodiment, the bladeless fan assembly is in the form of a domestic, portable standing fan 10 that includes a base 12 and an air outlet in the form of a nozzle 14 mounted on and supported by the base 12 . The base 12 includes a generally cylindrical housing 16 optionally mounted on a disc-shaped base floor 18 . The housing 16 includes a plurality of air inlets 20 in the form of apertures formed in the housing 16 through which the primary airflow is drawn into the base 12 from the external environment. The base 12 also includes a plurality of user-operable buttons 21 and a user-operable dial 22 for controlling the operation of the fan 10 . In this embodiment, the base 12 has a height ranging from 100 to 300 mm and the housing 16 has a diameter ranging from 100 to 200 mm.

[0035] The nozzle 14 has an elongated, annular shape and defines a central elongated opening 24 . The nozzle 14 has a hei...

Abstract

A fan assembly for creating an air current comprises an air inlet (20), an air outlet (14), an impeller (64) and a motor (68) for rotating the impeller to create an air flow passing from the air inlet to the air outlet. The air outlet (14) comprises an interior passage (94) for receiving the air flow and a mouth (26) for emitting the air flow. The air outlet defines an opening (24) through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The motor (68) has a rotor which, in use, is capable of rotating at a speed of at least 5,000 rpm.

Description

technical field [0001] The invention relates to a fan assembly. In a preferred embodiment, the present invention relates to a domestic fan, such as a tower fan, for creating air flow in a room, office or other domestic environment. Background technique [0002] Conventional household fans typically include a set of blades or vanes mounted for rotation about an axis and a drive for rotating the set of blades to create an airflow. The movement and circulation of the airflow creates a "wind chill" or breeze, and thus, the user feels a cooling effect as heat is lost through convection and evaporation. [0003] Such fans are available in a variety of sizes and shapes. For example, ceiling fans may be at least 1 m in diameter and are typically mounted in a suspended fashion from the ceiling to provide downward airflow to cool a room. Table fans, on the other hand, typically have a diameter of about 30 cm and are usually free standing and portable. Floor standing fans typically...
