Benefits of technology

[0009]It is postulated that the effectiveness of the invention is due to the interruption or modification of the air flow from the inside of the fireplace towards the inside surface of the panel. However, the preferred and other contemplated embodiments are effective and the claims made herein are not dependent on a definitive understanding of why the invention works.
[0010]The foregoing was intended as a broad summary only. It was not intended to define the limits or requirements of the invention. Various aspects of the invention will be appreciated by reference to the

Problems solved by technology

A common but persistent problem with gas-burning fireplaces is the buildup on the inside surface of the front window of a milky or hazy film.
Regardless of the cause, the film is perceived to be a problem and detrimental to the look of the fireplace.

Embodiment Construction

[0018]FIG. 1 illustrates the milky white haze or film 10 that tends to build on the inside of the window panel 12 of gas-burning fireplaces 14.

[0019]FIGS. 2, 3, 4 and 6 illustrate an embodiment of the invention. According to the invention, a screen 16 is provided so as to substantially span the inside surface of the window panel 12 of the gas fireplace 14. As can be appreciated by reference to FIG. 4, the screen 16 is spaced from the inside surface 18 of the panel 12 by a short distance “d”. The screen 16 lies in a plane 20 that is substantially parallel to the plane 22 of the panel 12 so that a reasonably consistent spacing d between the panel and the screen is maintained. In one or more embodiments, the distance d is between ¼ and 1 inch but may be as much as 8 inches.

[0020]Referring to FIG. 4, the screen 16 is secured by means of a bent portion 24 of the peripheral screen frame 26 that is seated in a gap 28 between the window panel 12 and an inside shoulder 30 of the frame of the...

Abstract

A means for avoiding the build up of a film on the inside surface of the transparent window of a gas fireplace comprises providing a mesh screen spaced a short distance of the inside surface. The mesh screen is believed to interrupt the flow of gases toward the window thereby preventing the build up.

Description

[0001]This application claims priority to Canadian Patent Application XXXXXXXX, filed 20 Mar. 2008, the specification of which is hereby incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to gas-burning fireplaces. In particular, this invention relates to a means of preventing the buildup of milky film on the inside of the transparent front panel of a gas-burning fireplace.[0004]2. Description of the Related Art[0005]A common but persistent problem with gas-burning fireplaces is the buildup on the inside surface of the front window of a milky or hazy film. The film detracts from the appearance of a fireplace and from the ability to appreciate the fire within.[0006]While the cause of the film is not clearly known, some manufacturers have speculated that it is the result of the curing process of the paint and log sets used in the fireplaces. It has also been suggested that the white film deposit arises from additives...
