EP0636841A2 - Automatic shut-off for a gas burner - Google Patents

Abstract

Starting from a deliberate assembly of a sensory element and a valve incorporated in the gas pipe with connection to the electric circuit, the invention consists in triggering without any manual intervention of its user the gas burner of a professional type gas cooker by the simple positioning of a pan, casserole or pot on the burner. The system can be used in all professional cookers and makes it possible to save on the consumption of gas and to reduce the loss of oxygen and the development of high temperatures in closed places. <IMAGE>

Description

The invention constitutes a perfecting and innovative mechanism for the use of gas burners used especially in industrial type kitchens, restaurants, hotels, hospitals and other large food supply services.

In the technical field of professional-type gas stoves, the only main and traditional gas switch is known, which must be used manually for all ignition and extinction of the burner.

The invention consists of an assembly of different elements known in the art, however, implying a new inventive result.

From the traditional gas burner stove, and using a sensor, a sensory element, an electronic valve of the SOLANOID type, a burner self-ignition / self-extinguishing system burner is designed.

By placing a frying pan, a saucepan, a pot (etc, ...) on the burner, the sensor electrically triggers the opening of the gas valve (electronically directed) specially installed, so that the burner lights up.

In the opposite direction, the removal of said pans, saucepan, pot (etc, ...), will be perceived by the sensor and triggers the extinction of the burner.

• d'économiser du gaz (jusqu'à 70 %),
• de réduire les pertes d'oxygène,
• de réduire les températures élevées,

dans toute cuisine de type industriel ou professionnel, alors que le brûleur à gaz ne sera allumé qu'au seul moment où la cuisson est faite et que les poêle, casserole et pot y nécessaires sont apposés sur le brûleur.The object and the invention are:

• save gas (up to 70%),
• reduce oxygen losses,
• reduce high temperatures,

in any industrial or professional kitchen, while the gas burner will not be lit until the cooking is done and the necessary pan, saucepan and pot are affixed to the burner.

The system also offers maximum security.

The invention is set out below in more detail on the basis of a drawing representing the embodiment of the invention.

The figure shows the traditional operating system of a gas burner (points 1, 2, 7, 8, 9) to which will be added an improvement system consisting of the present invention.

The traditional gas burner system consists of a main line (1), a safety valve in combination with a pilot light with thermocouple (7,8), and the burner itself (9).

The inventor adapts to this traditional functional system an assembly composed of a sensory element (5), a connecting rod or a sensor (4) to trigger the sensor, an electric / electronic valve (3) incorporated in the gas pipe, as well as the connection of the invention to the electrical circuit.

The sensory element and the triggering sensor relating thereto may consist of an inductive, electrostatic, magnetic, electro-optical or even reactive system to sound.

The valve can be of the "SOLANOID" type and the size depends on the size of the burner gas tubes.

The system can be functional from an electrical circuit of 24V or 220V AC, otherwise 24V DC.

Claims (2)

The inventor claims protection for the system and the technique of assembling a sensor with a sensory element, of an electric / electronic valve directed from said sensor for the opening or closing of the gas line of a gas burner, and whose system operates from a connection to the 24V - 220V AC or 24V DC electrical circuit. The characterizing element of the invention consists of the possibility of triggering, without any manual intervention, the ignition or extinction of the professional type gas burner from the sensor perceiving the installation of a kitchen tool ( stove, saucepan, etc.) on the burner.
