BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a stove with automatic control, more specifically an automatic and intelligent stove, that provides for a more practical, secure, rational and efficient use.
It is known that standard stoves basically have a burner set linked to a gas conductor network and also a flame burner ignited by an electrically generated spark.
Actually, technological improvements related to stoves have been very simple and inefficient in terms of their specific function, that is, heating food.
The relatively few technological improvements applied to stoves are directed to the starting operation and not specifically to the heating of containers of food.
Even the most technologically advanced stove still presents disadvantages in terms of safety, economy and operational rationalization, and does not guarantee the sensory aspects (smell, sight, texture, color, taste) and food nourishment value.
The use of a computer to automate the procedures of food preparation is disclosed by J. Carl Goodhouse in Brazilian patent No. 3889,875 granted on Jun. 17, 1975, where the cooking time is automatically set in terms of weight, cooking degree (well done, medium, rare) and a factor for each meat type, always considering a fixed cooking temperature.
The current invention is not restricted to meat preparation. It provides for programming cooking via variable parameters of temperature, dehydration degree, vapor and weight, controlled by a computer. This permits automating all types of food preparation in order to provide food with total quality, defined as: delicious, nourishing, variable and easy to be prepared. This invention not only controls the oven, but also all the stove burners, and the characteristics of the automatic control. This allows a better interaction with the user, protection against improper use, defects, violations, and thus provides comfort and safety. The stove can also be manually programmed via a numeric keyboard or remotely from a distance by telephone, computer program, CD ROM, ROM card, tape or OCR-Scanner, or any other media or storage system that uses data storage (procedure information). All these characteristics and benefits are discussed below.
OBJECTS OF THE INVENTION
One object of the invention is to supply a stove with an automatic control that brings high security to the user avoiding gas exhaust, improper operation or the burning of food during its preparation.
Another object is to supply the stove with an automatic control that limits its use to qualified persons, avoiding non-authorized use, such as by children.
One more object is to supply the stove with an automatic programming control, allowing a rational, fast and orderly use of the stove.
BRIEF DESCRIPTION OF THE INVENTION
The objects mentioned above and others are obtained with the stove fitted with an automatic control for the basic flame operating system. A pan is rested over the oven or burner grid together with support subsystem sequences integrated with a basic system that warns of all the stove operational variants (temperature, time, dehydration degree, vapor percentage and food or ingredients weight). The support subsystems include a flame sensor system; timer; a "weight" checking system of food to be prepared; a nearness sensor system and an identifier of utensils and persons authorized to operate the stove; a sound and visual alarm system connected to the other subsystems status; an auxiliary electrical feeding system; an oven pre-heating system; a water vapor supplier and regulator for the oven; a system to measure the temperature of the oven; a variable programming system (time.times.temperature.times.vapor.times.dehydration degree) to prepare the best food; a system based on a bar code scanning system that automatically programs the stove with variable parameters of (time.times.temperature.times.vapor dehydration degree); an automatic operating system of external ventilation and light focus over the burner table.
