Abstract
Abstract The electric towel warmer is constructed and arranged for receiving a towel therein and for maintaining the towel in a warm condition. The towel warmer includes a housing mounting an M-shaped heating element in the housing in a generally upright plane. A perforated cover is situated in the housing over the heating element and is spaced from the sidewalls of the housing to provide a space between the sidewalls of the housing and the cover for a towel. A movable top closure is mounted to the housing for covering the top of the housing. Electric circuitry is connected to the heating element and is adapted to be connected to an AC power source for controlling the current input to the heating element.

Claim 1
Independent Claim
254 words
In an electric towel warmer comprising a heating element adjacent to which a towel is placed for warming the same, means covering said heating element and control circuitry for controlling the electric current to the heating element, the improvement residing in the combination of: said heating element being configured and arranged to be in a generally upright plane, said cover means having openings therein to facilitate heat transfer by convection, conduction, and radiation from said heating element through said cover means and being sized and arranged to fit over said heating element in spaced relationship thereto in a generally upright position for supporting a towel draped thereover; said towel warmer including a housing completely surrounding said heating element and said cover means, said housing having spaced apart end walls and sidewalls, an open bottom and an openable top closure with said heating element being mounted on a base within said housing with said base closing off the bottom of said housing, said cover means extending between said end walls and being situated between and spaced from said sidewalls, such that a towel received in said housing through said openable top closure and draped over said cover means has one portion situated between one sidewall and said cover means and another portion situated between the other sidewall and said cover means, and said control circuitry including means within said cover means in circuit with said heating element for maintaining the temperature within said housing at a temperature adequate to warm a towel in said housing.
