A cooking enclosure is configured to hold food being cooked. The enclosure includes a surrounding, generally vertical, sidewall, projecting upward from a base. The base includes a floor bridging a bottom of enclosure, and the enclosure is capped by a vertically moving ceiling. The vertical moving ceiling secures a cooking heat source which is in thermal communication with the enclosure interior. The moving ceiling is configured to move up and down within the sidewall to vary, up and down, a volume of the cooking enclosure. The cooking enclosure is configured to have both a smaller cooking enclosure volume, suitable for quickly cooking small foods, and larger cooking enclosure volume necessary to cook larger foods.

A viewport for a combustion zone includes an inner casing having a flange extending into the combustion zone. A first layer of ceramic fiber insulation is exterior to the inner casing. A middle casing includes two panes of quartz glass separated by traverse plates. A second layer of ceramic fiber insulation is exterior to the middle casing. An outer casing is positioned to the exterior of the second layer of insulation. The middle casing includes L-shaped ledges having third and fourth layers of ceramic insulation. The panes of glass are each positioned between layers of insulation and the insulation positioned in the L-shaped ledges. The viewport is modular enabling the separation of the first layer of insulation, the middle casing, the second layer of insulation and the outer casing from the combustion zone for maintenance or repair. The viewport minimizes heat migration to the outer casing during use.

A heating cooking device includes: heating chamber having front face opening; and a heater to heat object to be heated stored in heating chamber. The heating cooking device further includes: camera that has optical axis inclined with respect to a vertical direction and is disposed on upper wall of heating chamber to face inside of heating chamber; and first illuminator that illuminates the inside of heating chamber from a side of upper wall of heating chamber. The heating cooking device further includes top panel that is disposed below upper wall of heating chamber, is formed of a semitransparent member to illuminate downward while diffusing light from first illuminator, and is provided with top panel opening serving as an opening through which camera images the inside of heating chamber.

A domestic cooking appliance for heating a food item includes a main housing; a cooking chamber located in the main housing and configured to receive the food item, the cooking chamber having side panels, and a back panel; a heater cover panel located in a lower region of the cooking chamber, the heater cover panel being one of translucent and transparent; and a heater that produces heat for heating the cooking chamber, the heater being located below the heater cover panel. The heater is visible through the heater cover panel.

The present invention relates to a plate, intended to equip appliances of the chimney insert, stove, chimney, boiler, heating appliance, fireplace or equivalent type and/or to serve as a fire barrier, said plate being formed of at least one glass-ceramic substrate coated on at least one of its faces with the following stack of layers: 1. a first metal nitride layer of thickness comprised in the range from 5 nm to 50 nm, 2. an indium tin oxide layer of less than 100 nm thickness, 3. a second metal nitride layer of thickness comprised in the range from 10 nm to 100 nm.

The present invention also relates to a process for obtaining said plate, as well as a device incorporating said plate.
