A stove for cooking food, said stove comprising:
- a stove body;
- said stove body being configured with a support comprising feet;
- said stove body being configured with an interior confined by walls comprising side walls, a front wall, and a rear wall;
- an oven;
- a heating arrangement configured and disposed to provide heating to cook food in said oven;
- control apparatus to control said heating arrangement;
- a door in said front wall;
- said door comprising a window arrangement configured with a viewing area to view food being cooked in the interior of said oven;
- said window arrangement comprising a first pane and a second pane disposed at a distance from said first pane;
- said first pane becoming the inner pane upon installation in said stove;
- said second pane becoming an outer pane upon installation in said stove;
- an arrangement to maintain said first and second panes in spaced relationship;
- and
- a roller blind arrangement disposed between said first and second panes;
- said roller blind arrangement comprising:
- a first roller;
- said first roller comprising an elongated, round cylindrical structure having a length;
- a sheet connected to said first, cylindrical, roller;
- said sheet comprising a continuous sheet having a width and a length;
- said width of said sheet being approximately equal to said length of said first, cylindrical, roller;
- said sheet being configured to be wound onto said first, cylindrical, roller and said sheet being configured to be unwound from said first, cylindrical, roller;
- and
- actuating apparatus configured and disposed to position said sheet into a first position, to obscure viewing into the interior of said oven, upon said sheet being unwound from said first, cylindrical, roller;
- said actuating apparatus further being configured and disposed to position said sheet into a second position, to permit viewing into the interior of said oven, upon said sheet being wound onto said first, cylindrical, roller;
- said sheet being configured, when in said first position:
- to obscure viewing into the interior of said oven,
- to minimize heat radiation from said heating arrangement reaching the ambient surrounding of said stove,
- to provide a substantially uniform heat reflection of heat impinging upon said sheet, and
- to provide a substantially uniform heat reflection of impinging heat into said oven from all portions of the interior of said oven.

- actuating apparatus configured and disposed to position said sheet into a first position to obscure viewing into the interior of said oven;
- said actuating apparatus further being configured and disposed to position said sheet on said first, cylindrical, roller into a second position to permit viewing into the interior of said oven;
- said sheet being configured, when in said first position:
- to obscure viewing into the interior of said oven,
- to minimize heat radiation from said heating arrangement reaching the ambient surrounding of said oven, and
- to provide a heat reflection of heat impinging upon said sheet into said oven.
19 more elements
An appliance, comprising one of:
- an oven, a stove, a baking appliance, a cooking appliance, a refrigerator, a freezer chest, a freezer, a microwave appliance, and a space heater, said appliance comprising a viewing window, said viewing window being configured to be mounted in or form at least a portion of a wall of said appliance, said viewing window comprising:
- at least two transparent panes arranged at a distance from one another and providing a viewing area;
- an arrangement to maintain said first and second panes at a distance from one another;
