Abstract

The IR radiation-reflective base for burners is intended to make harnessing heat from the flame more efficient, re-directing the IR radiation that is not used towards the cooking utensils on a domestic stove burner. An IR reflective surface (4) can be incorporated into the base of the cooker or raised above same so as to be closer to the flame. In the latter case, the surface can be: supported by three or more elevating feet (7), joined directly to the bars (3) that support the cooking utensils, or joined directly to the burner (2). Cavities (9) are formed between the above-mentioned feet (7) and air can enter through said cavities for gas combustion. In addition, a heat-insulating material can be added to the other face of the reflective surface (4).

Description

BASE REFLEJANTE DE RADIACIÓN IR PARA QUEMADORES.  REFLECTING BASE OF IR RADIATION FOR BURNERS.
La presente invención se inscribe según la Clasificación Internacional de: F24C15, F24C3, F23D14, A47J27. The present invention is registered according to the International Classification of: F24C15, F24C3, F23D14, A47J27.
ESTADO DE LA TÉCNICA ANTERIOR STATE OF THE PREVIOUS TECHNIQUE
No se conocen dispositivos tales como los expresados en la presente invención. EXPLICACION DE LA INVENCIÓN  There are no known devices such as those expressed in the present invention. EXPLANATION OF THE INVENTION
La presente invención tiene por objetivo hacer más eficiente el aprovechamiento del calor de la llama, aprovechando la radiación infrarroja (IR) o calorífica, que por ejemplo radia hacia abajo en un fuego de cocina de gas doméstica. Dicha radiación normalmente se pierde en forma de calor en la base de soporte del quemador, pero se puede aprovechar para calentar más el utensilio de cocción (olla, sartén, etc) si dicha radiación IR es reflejada hacia arriba, hacia dicho utensilio. Resultando así, un mayor aprovechamiento del calor del fuego del gas y por tanto un ahorro de gas para el mismo resultado.  The present invention aims to make more efficient use of heat from the flame, taking advantage of infrared (IR) or heat radiation, which for example radiates down in a domestic gas cooking fire. Said radiation is normally lost in the form of heat in the support base of the burner, but it can be used to heat the cooking utensil (pot, pan, etc.) more if said IR radiation is reflected upwards towards said utensil. Thus, a greater use of the heat of the gas fire and therefore a saving of gas for the same result.
Para ello se dispone de una superficie reflectora (4) de los IR que se sitúa en uno de los lados de la llama o llamas, ya sea incorporada o integrada en la misma base de la cocina donde se apoyan los quemadores, ya sea colocada elevada respecto la base de la cocina, para estar más cerca de la llama o llamas. También dicha superficie reflejante de los rayos infrarrojos podría envolver la llama o llamas dejando abierto el extremo final de la llama o llamas.  For this, a reflective surface (4) of the IRs is available, which is located on one of the sides of the flame or flames, either incorporated or integrated in the same base of the kitchen where the burners are supported, whether placed high respect the base of the kitchen, to be closer to the flame or flames. Also said reflecting surface of the infrared rays could wrap the flame or flames leaving the final end of the flame or flames open.
La superficie reflectora (4) si está incorporada en la base de la cocina puede ser una corona circular o bien unos sectores circulares (ver figura 2) en el caso de que no se use dicha superficie reflectante debajo de las barras de soporte de los utensilios de cocción (3). También dicha superficie reflectora (4) puede seguir la forma que tenga la proyección de la llama sobre la base de la cocina, o de los quemadores. The reflective surface (4) if it is incorporated in the base of the kitchen can be a circular crown or circular sectors (see figure 2) in the case that said reflective surface is not used under the support bars of the utensils of cooking (3). Also said reflecting surface (4) can follow the shape of the projection of the flame on the base of the kitchen, or of the burners.
La superficie reflectora (4) colocada elevada más cerca de la llama y siguiendo más o menos su inclinación o su forma, puede ser soportada mediante tres o más patas (7) que la eleven, o bien unida directamente a las barras de soporte de utensilios de cocción (3), o también directamente soportada o unida por unos puntos o unas patas al quemador (2). En el caso de ser una pieza que se eleva con unas patas (7) y que se centra mediante unos piés (8) al quemador (2), dichas patas (7) dejan unos huecos (9) importantes por cuanto por ellos va a entrar el aire y su oxígeno para la combustión del gas, y también por ellos podría drenar el líquido o parte del líquido que accidentalmente pueda salir del utensilio de cocción y caer sobre la superficie reflectora (4). Dicha superficie reflectora (4) puede tener unas hendiduras por las que pueden alojarse las barras de soporte de los utensilios de cocción (3). The reflecting surface (4) placed elevated closer to the flame and more or less following its inclination or shape, can be supported by three or more legs (7) that raise it, or directly attached to the tool support bars of cooking (3), or also directly supported or joined by points or legs to the burner (2). In the case of being a piece that rises with legs (7) and that is centered by means of feet (8) to the burner (2), said legs (7) leave some important holes (9) because they are going to Entering the air and its oxygen for the combustion of the gas, and also by them it could drain the liquid or part of the liquid that could accidentally leave the cooking utensil and fall on the reflecting surface (4). Said reflecting surface (4) may have slits through which the support bars of the cooking utensils (3) can be housed.
Todo lo explicado para la superficie reflectora (4) se le puede añadir un material aislante del calor en el lado contrario a la superficie reflectora (4), al objeto de que dicha superficie reflectora (4) no enfrie la llama, y que a su vez al calentarse dicha superficie reflectora ya que no evacúa el calor al tener dicho material aislante, radie a su vez en la dirección a la base del utensilio de cocción. Everything explained for the reflecting surface (4) can be added a heat insulating material on the opposite side to the reflecting surface (4), in order that said reflecting surface (4) does not cool the flame, and that its Once said reflective surface is heated, since it does not evacuate heat by having said insulating material, turn in the direction to the base of the cooking utensil.
