AI Technical Summary

Benefits of technology

The present invention relates to electrically powered fans, and in particular, to residential wall-mounted fans. The invention provides fans that can be easily mounted on a wall and operate at variable speeds. The fans have a small wall-mounting surface area and can operate on a single hot-wire in a two wire system. The fans also have a wireless receiver for receiving input from a wireless device and a controller for adjusting motor speed. The technical effects of the invention are improved efficiency, flexibility, and ease of installation.

Problems solved by technology

Additionally, AC motors are less efficient, and thus more expensive to operate, than DC motors.
These switch systems, when used with wall-mounted fans, take up a lot of space on the wall, creating a less visually appealing structure.
However, the two hot wire in a three wire system can be complicated for residential customers and may require costly electrical modifications in residences wired with a single hot wire in a two wire system.
Additionally, the splitting device used with AC is large and not aesthetically pleasing in the residential context.

example 1

[0040]In the first example, the fan blade motor 132 and oscillator motor 134 are DC motors. To ensure the desirably small size of the base 120, both the fan blade motor 132 and the oscillator motor 134 may operate at variable speeds, but do not have to operate at variable speeds. In this example, the controller 136 is capable of operating each of the fan blade motor 132 and the oscillator motor 134 at individual, variable speeds, if desirable.

example 2

[0041]In the second example, the fan blade motor 132 is a DC motor and the oscillator motor 134 is an AC motor. To ensure the desirably small size of the base 120, only the fan blade motor 132 is capable of being controlled by the controller 136 to operate at variable speeds. The oscillator motor 134 may only operate in an “on” and an “off” state, which may be controlled by the controller 136.

example 3

[0042]In the third example, the fan blade motor 132 is an AC motor and the oscillator motor 134 is a DC motor. To ensure the desirably small size of the base 120, only the oscillator motor 134 is capable of being controlled by the controller 136 to operate at variable speeds. The fan blade motor 132 may only operate in an “on” and an “off” state, which may be controlled by the controller 136.

Abstract

A wall-mounted fan, such as used in residential settings, includes a base, an arm, and a housing. The housing includes an oscillator motor and a fan blade motor that may be operated at variable speeds. The arm connects the housing to the base and the base connects the wall-mounted fan to the wall.

Description

BACKGROUND OF INVENTION[0001]Electrically powered fans can be powered by either alternating current (AC) or direct current (DC) motors. AC motors are generally larger and louder than their DC counterparts. Additionally, AC motors are less efficient, and thus more expensive to operate, than DC motors. Fans that operate with AC motors require speed control by large surface switch systems on the base of the fan in order to provide variable speed. These switch systems, when used with wall-mounted fans, take up a lot of space on the wall, creating a less visually appealing structure.[0002]Additionally, many fans incorporate other electrically powered devices into the fan. For example, ceiling fans often include a light and wall-mounted fans often include an oscillating motor. In order to have separate control of the fan motor and any other electrically powered device(s), either separate electrical power is required, leading to the use of two hot wires in a three wire system (one hot wire...
