Embodiment Construction

[0044] A fan assembly will now be described that automatically adjusts the speed of the motor driven impeller according to the current air quality. As used herein, the term "fan assembly" refers to a fan assembly configured to generate and deliver airflow for thermal comfort and / or environmental or climate control purposes, and particularly, but not exclusively, for use in a room , household fans that create air circulation and airflow in an office or other home environment. Such fan assemblies may be capable of generating one or more of dehumidified airflow, humidified airflow, purified airflow, filtered airflow, cooling airflow, and heated airflow.

[0045] figure 1 An embodiment of a fan assembly suitable for implementing the methods described herein is schematically shown. The fan assembly 100 is implemented as a combination of mechanical components, computer hardware and software, and includes a motor-driven impeller 110 arranged to generate an airflow, an air outlet 12...

Abstract

A fan assembly is provided comprising: a motor-driven impeller arranged to generate an airflow; an air outlet arranged to emit the airflow; at least one filter assembly arranged to purify the airflow; arranged to measure each of a plurality of air quality characteristics multiple sensors of a value; and a processor. The processor is configured to receive a measurement of each of the plurality of air quality characteristics, identify one of a corresponding set of intervals into which the measurement falls, select an air quality indicator value associated with the identified interval, and use the The selected air quality index value generates a corresponding velocity value. The processor is then configured to set the speed of the motor driven impeller according to the highest value of the speed value.

Description

technical field [0001] The present invention relates to a fan assembly and a computer-implemented method for controlling a fan assembly including a motor-driven impeller. Background technique [0002] A conventional household fan typically includes a set of blades or blades mounted for rotation about an axis, and a drive for rotating the set of blades to generate an air flow. The movement and circulation of the airflow creates a "wind chill" or breeze, and as a result, the user experiences cooling by dissipating heat through convection and evaporation. The blades are usually located within a cage that allows airflow through the housing while preventing the user from coming into contact with the rotating blades during use of the fan. [0003] US 2,488,467 describes a fan that does not use shrouded blades to eject air from the fan assembly. Instead, the fan assembly includes a base and a series of concentric annular nozzles, the base housing a motor-driven impeller for drawi...
