Household fan for providing the feel of a natural breeze

摘要

A household fan for providing the feel of a natural breeze includes a motorized impeller for providing airflow, a controller coupled to the motorized impeller for changing characteristics of the airflow, and an interface in communication with the controller for receiving human instructions. The fan further includes a breeze setting to be selected by way of the interface and implemented via the controller to operate the motorized impeller. The breeze setting varies intensity of the airflow that is output by the motorized impeller such that local extrema of the intensity are related to numbers selected by way of random number generation within a bounded range or numbers drawn from a sequence of substantially non-consecutive numbers.
