Abstract

A glass panel for an electric oven has an internal surface thereof coated with reflective paint. The reflective paint may be a paint mixed with stainless steel and silver powder, chromium powder or silver powder.

Description

2366613 GLASS PANEL FOR AN ELECTRIC OVEN This invention relates to a glass
panel for an electric oven.
5 Conventional electric ovens, which term includes a microwave oven and a toasting oven, often are provided with a panel made of transparent glass.
Figure 1 shows a vertical cross-sectional view of a known electric oven having a transparent glass panel 1 for 10 viewing food being cooked, the glass panel being located in a door of the oven. Radiant rays are shown in broken arrow-headed lines.
Such a known electric oven has the following disadvantages:
15 1. The transparency of the glass panel is normally high and has a bad reflectivity causing electro-thermal rays to leak through the glass panel and thereby lose energy from the oven.
2. Due to the leakage and loss of electro-thermal 20 rays through the glass panel, cooking efficiency is lowered, there is wasted energy and temperature is lost to the external atmosphere.
3. If the glass panel is situated in a microwave oven, the rays generated when the oven is heated may pass 25 through the highly transparent glass panel and cause damage to humans.
It is known that rays having some wavelengths are harmful to human skin, such as ultraviolet rays, and it is, therefore, an object of the present invention to provide an 30 improved glass panel for an electric oven.
According to this invention there is provided a glass panel for an electric oven-has an internal surface thereof coated with paint, said paint being mixed with high reflectivity material.
5 Preferably, said paint is mixed with stainless steel and silver powder, chromium powder, or silver powder.
Advantageously, said glass is transparent glass or tinted glass.
The invention will now be described, by way of 10 example, with reference to the accompanying drawings, in which:
Figure 1 shows a cross-sectional view of a known electric oven, and Figure 2 shows a vertical cross-sectional view of a 15 glass panel for an electric oven in accordance with this invention.
Referring to Figure 2, an electric oven 10 has an outer casing 11 and an inner, radiant reflective inner lining 12. Located within the lining 12 is a shelf 13 upon 20 which is diagrammatically shown an item 14 being baked. The oven has a pivotal door 15 in which is located a reflective glass panel 16.
The glass panel has an internal surface 17 which is coated with a reflective material such as a reflective 25 paint. Experimental results show that ordinary paints usually absorb heat and slow down the heating of the electric oven, but in this invention the paint used to coat the inside surface of the glass panel 16 has materials providing good reflectivity mixed with the paint. Such 30 materials are stainless steel and silver powder, chromium powder or silver powder. Such a paint increases the efficiency of reflectivity of the interior side of the glass and reduces the leakage of radiant rays. Furthermore, damage to the human body and energy loss is avoided. The rays are shown in Figure 2 by broken arrow- 5 headed lines and it will be seen that the rays are reflected, not only from the lining 12, but also from the internal surface 17. The rays reflected by the internal surface 17 into the interior of the oven increase the heating effect of the oven and the oven is better able to provide even heat disbursement and is energy saving.
The glass panel 16 may be initially a transparent glass or a tinted glass. Since tinted glass, itself, is almost opaque, it reduces the leakage of radiant rays to the outside of the oven.
15 The structure of the present invention has the following advantages:
1. It increases the reflectivity of the internal side of the glass panel and reduces the leakage of radiant rays to prevent damage to human bodies.
20 2. It enhances the heating effect and attains even heat dispersion with energy-saving effects.
3. It maintains the function of viewing the interior portion of the oven. In this respect, although the painted interior surface tends to make the glass panel, as viewed 25 externally, into a mirror when the oven is not in operation, when the oven is operated light generated by an electric heater within the oven or an internal lamp within the oven allows users to see through the glass panel and view the food being cooked.
CT-AIMS:
1. A glass panel for an electric oven has an internal surface thereof coated with paint, said paint being mixed with high reflectivity material.
2. A glass panel as claimed in claim 1, wherein said paint is mixed with stainless steel and silver powder, chromium powder, or silver powder.
3. A glass panel as claimed in claim 1 or 2, wherein said glass is transparent glass or tinted glass.
4. A glass panel substantially has herein described with 15 reference to, and as shown in, Figure 2 of the accompanying drawings.
