Problems solved by technology

For example, hands-free paper towel dispensers permit paper towels to be dispensed as may be needed without a user having to touch a mechanical surface, which may have been contaminated by people who previously used the mechanical towel dispenser without washing their hands or without having washed their hands well.

Embodiment Construction

[0033] Disclosed herein is an improved electronic touch-less sheet product dispenser. As will be discussed in greater detail below, embodiments of the touch-less electronic dispenser include a number of improvements over existing touch-less electronic dispensers. For example, in one embodiment, the dispenser can be recessed into a wall as a single unit, thereby allowing for minimal space consumption by the dispenser. In other embodiments, improvements have been made to infrared detection circuitry that allows for variable sensitivity in infrared detection. Embodiments illustrated also advantageously use a minimal number of parts for both the mechanical structure and for the electronic unit. It has, therefore, an enhanced reliability and maintainability, both of which contribute to cost effectiveness. Additional improvements and advantages will be understood by those skilled in the art in light of the following descriptions.

Abstract

An electronic dispenser for dispensing sheet products includes an infrared proximity sensor operative to detect a presence of a user's hand at a predetermined location near the dispenser and a feed mechanism configured to engage a sheet product roll to cause a quantity of sheet product to be dispensed therethrough. The infrared proximity sensor is configured to have an adjustable sensitivity to vary a detection range of the infrared proximity sensor. The feed mechanism has a motor operative in response to the infrared proximity sensor to engage the feed mechanism.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of the filing dates of U.S. Provisional Patent Application No. 60 / 774,390, filed Feb. 18, 2006 and U.S. Provisional Patent Application No. 60 / 802,612, filed May 22, 2006, which are herein incorporated by reference in their entirety.BACKGROUND [0002] The present disclosure generally relates to sheet product dispensers such as paper towel dispensers, and more particularly, to electronic dispensers for touch-less dispensing of sheet products. [0003] Sheet product dispensers, such as paper towel dispensers, are often provided in public washrooms, adjacent to sinks and in other areas where a convenient and disposable drying medium is desired. Sheet product dispensers that allow “hands-free” or “touch-less” dispensing have recently grown in popularity in public washrooms, as a result of an increased awareness by the public to hygiene. For example, hands-free paper towel dispensers permit paper towels to be ...
