Abstract
Description
La presente invención se refiere a un sistema de regulación de la temperatura en el recinto de cocción de hornos tradicionales que usan como fuente de calor combustibles sólidos tales como leña, carbón o similares y, así mismo, a un horno especialmente adaptado para aplicar este sistema de regulación de la temperatura. El horno presenta características específicas y partes fundamentales e integra, como método principal de funcionamiento, el sistema de control objeto de la invención. The present invention relates to a temperature regulation system in the cooking oven of traditional ovens that use solid fuels such as firewood, coal or the like as a source of heat and, also, to a furnace specially adapted to apply this system of temperature regulation. The oven has specific characteristics and fundamental parts and integrates, as the main method of operation, the control system object of the invention.
En los hornos tradicionales de leña o carbón es imposible regular de forma controlada y automática la temperatura del habitáculo de cocción, aunque si es posible conocerla mediante un termómetro. El aumento de la temperatura se consigue por la aportación de elementos combustibles (leña, carbón o similar) y es imposible hacerlo durante el proceso de cocinado, pues la cámara de combustión y cocción son la misma. La disminución de la temperatura se consigue por la dispersión natural del calor con el consiguiente tiempo de espera no controlado. In traditional wood or coal ovens, it is impossible to control the temperature of the cooking compartment in a controlled and automatic way, although it is possible to know it by means of a thermometer. The increase in temperature is achieved by the contribution of combustible elements (firewood, coal or similar) and it is impossible to do so during the cooking process, since the combustion and cooking chamber are the same. The decrease in temperature is achieved by the natural dispersion of heat with the consequent uncontrolled waiting time.
Sería por lo tanto deseable aplicar, en primer lugar, cambios en la estructura básica del horno y en segundo lugar, la integración de un sistema que controle de forma automática y precisa la temperatura de cocción, aspectos en los que se centra la presente invención. It would therefore be desirable to apply, in the first place, changes in the basic structure of the oven and secondly, the integration of a system that automatically and accurately controls the cooking temperature, aspects on which the present invention focuses.
La presente invención se refiere a un sistema automático de control de la temperatura de cocción que toma como referencia la temperatura previamente consignada, dando solución al inconveniente descrito. The present invention relates to an automatic cooking temperature control system that takes as reference the previously set temperature, giving solution to the inconvenience described.
Así mismo, el objeto de la invención se refiere a un horno de leña o carbón adaptado a la aplicación del sistema de control y regulación de la temperatura de cocción. Este horno consta de las partes fundamentales para que el sistema funcione correctamente, concretamente, el método que emplea en la aportación de calor a la cámara de cocción y la separación de la cámara de combustión y cámara de cocción. Likewise, the object of the invention relates to a wood or coal furnace adapted to the application of the cooking temperature control and regulation system. This oven consists of the fundamental parts for the system to function properly, specifically, the method used in the heat supply to the cooking chamber and the separation of the combustion chamber and cooking chamber.

El sistema de control y regulación de la temperatura está basado en controlar la cantidad de calor que incide en la cámara de cocción. Está integrado por: The temperature control and regulation system is based on controlling the amount of heat that affects the cooking chamber. It is composed of:
- --
- 2 termostatos 2 thermostats
- --
- 1 motor soplante (5) 1 blower motor (5)
- --
- 1 motor extractor (6) 1 extractor motor (6)
- --
- 1 cámara de calor (2) 1 heat chamber (2)
Partes que integran el horno: Parts that make up the oven:
- --
- 1 cámara de cocción (1) 1 cooking chamber (1)
- --
- 1 cámara de combustión (3) 1 combustion chamber (3)
- --
- 1 cajón recogida de cenizas (4) 1 ash collection drawer (4)
- --
- 1 panel de control (9) 1 control panel (9)
El sistema consta de dos termostatos: uno para consignar la temperatura mínima (T1) Y otro para la temperatura máxima (T2). The system consists of two thermostats: one to set the minimum temperature (T1) and another for the maximum temperature (T2).
La variación de las temperaturas de referencia consignadas activa el sistema para aumentar o reducir la temperatura dentro de la cámara de cocción. Por lo tanto, los termostatos son los encargados de controlar su funcionamiento. The variation of the set reference temperatures activates the system to increase or reduce the temperature inside the cooking chamber. Therefore, thermostats are responsible for controlling their operation.
El termostato de temperatura mínima (T1) es el encargado de controlar el funcionamiento del motor soplante (5) accionándolo cuando la temperatura está por debajo de la consignada. The minimum temperature thermostat (T1) is responsible for controlling the operation of the blower motor (5) by activating it when the temperature is below the set point.
El termostato de temperatura máxima (T2) es el encargado de controlar el funcionamiento del motor extractor (6) accionándolo cuando la temperatura supera la consignada. The maximum temperature thermostat (T2) is responsible for controlling the operation of the extractor motor (6) by activating it when the temperature exceeds the set point.
El motor soplante (5) inyecta aire del exterior para avivar el fuego dentro de la cámara de combustión (3). Esto acelera la creación de brasas y fuerza la ascensión de calor hacia la cámara de calor (2), con el consiguiente aumento de la temperatura dentro de la cámara de cocción (1). Se encuentra en la parte inferior del cajón de recogida de cenizas y se puede acceder a él a través del frontal extraíble (11). The blower motor (5) injects outside air to fan the fire inside the combustion chamber (3). This accelerates the creation of embers and forces the rise of heat into the heat chamber (2), with the consequent increase in temperature inside the cooking chamber (1). It is located at the bottom of the ash collection drawer and can be accessed through the removable front (11).
El motor extractor (6) es el encargado de extraer calor de la cámara de cocción, con la consiguiente disminución de la temperatura dentro de ésta, expulsándolo hacia el exterior a través de la salida de calor (8). Se encuentra en la parte inferior del cajón de recogida de cenizas y se puede acceder a él a través del frontal extraíble (11). The extractor motor (6) is responsible for extracting heat from the cooking chamber, with the consequent decrease in the temperature inside it, expelling it outwards through the heat outlet (8). It is located at the bottom of the ash collection drawer and can be accessed through the removable front (11).
La cámara de cocción (1) está dispuesta en la parte superior de la cámara de combustión (3) y está rodeada por la cámara de calor (2). Tiene una solera de ladrillo refractario para conservar el calor. En su parte frontal está situada la "boca" para introducir y extraer la comida. Tiene practicados dos orificios: Uno obturable (01) para dejar pasar a su interior parte del aroma de la leña concentrado en la cámara de calor y, en su parte superior, otro (02) que conecta con el motor extractor (6). En su interior se encuentran las sondas conectadas a los termostatos (S 1, S2). The cooking chamber (1) is arranged in the upper part of the combustion chamber (3) and is surrounded by the heat chamber (2). It has a refractory brick floor to conserve heat. On its front is the "mouth" to introduce and extract food. It has two holes: One sealed (01) to let in its interior part of the aroma of the firewood concentrated in the heat chamber and, in its upper part, another (02) that connects with the extractor motor (6). Inside are the probes connected to the thermostats (S 1, S2).
La cámara de calor (2) rodea a la cámara de cocción (1). En ella se concentra y circula el calor que mediante irradiación se transmite al interior del habitáculo de cocción. Tiene practicado un orificio en la parte superior a modo de chimenea (7) que conecta con el exterior. Su parte inferior está abierta a la cámara de combustión (3), protegida por un plato cerámico (10) que dirige el calor hacia su interior. The heat chamber (2) surrounds the cooking chamber (1). In it the heat is concentrated and circulated that is transmitted through irradiation into the interior of the cooking compartment. It has made a hole in the top as a chimney (7) that connects with the outside. Its lower part is open to the combustion chamber (3), protected by a ceramic plate (10) that directs heat inside.
La cámara de combustión (3) se encuentra debajo de la de cocción (1). Su base es de rejilla para tamizar la ceniza que se deposita por gravedad en el cajón inferior destinado para ello (4). Sus paredes laterales y trasera son inclinadas, formando un tronco de cono invertido, y la frontal es una puerta metálica, de cristal térmico o similar. Esta forma cónica, más amplia en la parte superior, facilita la distribución homogénea del calor. The combustion chamber (3) is below the cooking chamber (1). Its base is a grid to sift the ash that is deposited by gravity in the lower drawer destined for it (4). Its side and rear walls are inclined, forming an inverted cone trunk, and the front is a metal, thermal glass or similar door. This conical shape, wider at the top, facilitates the homogeneous distribution of heat.
El panel de control (9) se encuentra en el lateral derecho de la cámara de cocción (1) Y contiene: The control panel (9) is located on the right side of the cooking chamber (1) and contains:
- --
- Un pulsador luminoso de encendido general (EG) A general power light (EG)

El sistema de control y regulación de la temperatura funciona con energía eléctrica, por ello es necesario conectar el equipo a la red y para encenderlo y apagarlo dispone de un pulsador luminoso general(EG). The system of control and regulation of the temperature works with electrical energy, for this reason it is necessary to connect the equipment to the network and to turn it on and off it has a general light button (EG).
Tratándose de un sistema ideado para hornos que usan como fuente de In the case of a system designed for furnaces that they use as a source of
calor la combustión de leña, carbón o similar, es necesario un proceso de precalentamiento inicial para el correcto funcionamiento. heat the combustion of firewood, coal or similar, an initial preheating process is necessary for proper operation.
Una vez cargada la cámara de combustión, se prende la leña o carbón que después de arder se convertirá en brasas. Si es necesario para este proceso pondremos en marcha el motor soplante (5) para avivar el fuego accionando el pulsador luminoso dispuesto para ello (PL). Cuando el pulsador (PL) está en posición de apagado y el pulsador de encendido general (EG) está en posición de encendido, el motor soplante queda controlado por el termostato de temperatura mínima (T1). Once the combustion chamber is loaded, the wood or coal is ignited which after burning will become embers. If necessary for this process we will start the blower motor (5) to fan the fire by pressing the light button provided for it (PL). When the button (PL) is in the off position and the general power button (EG) is in the on position, the blower motor is controlled by the minimum temperature thermostat (T1).
Podemos conocer en todo momento la temperatura existente en el interior de la cámara de cocción observando el termómetro (TM) del panel de control. We can know at all times the temperature inside the cooking chamber by observing the thermometer (TM) of the control panel.
Después de estabilizada la combustión y generadas las brasas, encenderemos el sistema y estableceremos las temperaturas de referencia en los termostatos. Si ésta es diferente a la temperatura existente, entrará en funcionamiento el sistema. After the combustion stabilized and the embers generated, we will turn on the system and set the reference temperatures in the thermostats. If this is different from the existing temperature, the system will start operating.
En el caso de que la temperatura sea superior a la de referencia, el sistema pone en funcionamiento el motor extractor evacuando aire caliente. Una vez disminuya la temperatura y alcanzada la establecida, el motor extractor entra en reposo. In the event that the temperature is higher than the reference temperature, the system starts the exhaust motor by evacuating hot air. Once the temperature decreases and the set temperature has been reached, the extractor motor goes to rest.
Si por el contrario la temperatura es inferior, entra en funcionamiento el motor soplante para avivar la combustión y forzar la ascensión del calor hacia la cámara de calor, elevando la temperatura. En este caso hay que tener en cuenta que es posible que sea necesario añadir más leña o carbón a la cámara de combustión, pues la disminución de la temperatura puede ser causada por la carencia de brasas. If, on the contrary, the temperature is lower, the blower motor starts working to fuel combustion and force the heat to rise into the heat chamber, raising the temperature. In this case, it should be borne in mind that it may be necessary to add more wood or coal to the combustion chamber, as the temperature decrease may be caused by the lack of embers.
