Description

ESTUFA EXTERIOR ALIMENTADA CON PELLETS DE BIOMASA  OUTDOOR STOVE FEEDED WITH BIOMASS PELLETS
CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION
La presente invención se refiere a un aparato de calefacción o estufa diseñado para actuar principalmente en entornos exteriores y cuya fuente de alimentación energética son los pellets de biomasa.  The present invention relates to a heating apparatus or stove designed to act mainly in outdoor environments and whose energy source is biomass pellets.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En los últimos años, el número de países que han ido incorporando a su legislación la prohibición de fumar en lugares públicos ha ido aumentando de manera progresiva. Así, miembros de la Unión Europea como Irlanda, Noruega, Suecia, Italia, Francia, Holanda, Dinamarca, Bélgica o España, estados pertenecientes a los Estados Unidos de América como California y Nueva York donde la legislación es aún más restrictiva que Europa, Australia o algunas áreas de Canadá, son algunos de los principales ejemplos donde la prohibición de fumar en espacios públicos ha adquirido notoriedad de ley. Así, cerca de 51 países de todo el mundo (el 25% del total), 1 1 de ellos de la Unión Europea, no permiten fumar en locales de ocio, bares y restaurantes, pudiendo tomarse como ejemplo a España donde la Ley 42/2010, de 30 de diciembre de 2010, más conocida como "nueva ley antitabaco", entró en vigor el 02/01 /201 1 como modificación de la anterior ley de 2006 en este ámbito y cuyas medidas más importantes extienden la prohibición de fumar a cualquier local abierto al público de uso colectivo que no se encuentre al aire libre (con excepciones), e incluso a ciertos lugares abiertos definidos en la Ley.  In recent years, the number of countries that have incorporated into their legislation the prohibition of smoking in public places has been increasing progressively. Thus, members of the European Union such as Ireland, Norway, Sweden, Italy, France, Holland, Denmark, Belgium or Spain, states belonging to the United States of America such as California and New York where the legislation is even more restrictive than Europe, Australia or some areas of Canada, are some of the main examples where the prohibition of smoking in public spaces has acquired notoriety of law. Thus, about 51 countries around the world (25% of the total), 1 1 of them from the European Union, do not allow smoking in entertainment venues, bars and restaurants, being able to take Spain as an example where Law 42 / 2010, of December 30, 2010, better known as the "new anti-smoking law", entered into force on 02/01/201 1 as a modification of the previous law of 2006 in this area and whose most important measures extend the smoking ban to any premises open to the public for collective use that are not found outdoors (with exceptions), and even to certain open places defined in the Law.
Todas estas leyes han influido de manera clara en los establecimientos hosteleros los cuales, ante la prohibición de fumar en sus instalaciones, decidieron instalar terrazas exteriores para sus clientes donde estuviera permitido fumar y donde, buscando paliar el potencial frío en los días de temperaturas más bajas, se incorporaron de manera general estufas exteriores para la climatización del ambiente.  All these laws have clearly influenced hotel establishments which, before the prohibition of smoking in their facilities, decided to install outdoor terraces for their clients where smoking was allowed and where, seeking to alleviate the cold potential in the days of lower temperatures , outdoor stoves were generally incorporated for air conditioning.
Así, son varias las patentes existentes que describen este tipo de estufas. Por ejemplo el documento ES 1 044 127 U muestra un calefactor de gas para exteriores que posee el hogar situado en un punto elevado del mismo, de tal manera que irradia el calor allí generado en un amplio radio. Además, también se encuentran patentes con reivindicaciones de características concretas de los mismos, como por ejemplo el documento ES 1 073 802 U que describe un calefactor de gas para exteriores que incluye un sistema de pago para su uso, o el documento ES 2 167 913 T3 el cual describe un dispositivo de calefacción para terraza tipo paraguas. Además, también se encuentran descritas estufas de exteriores alimentadas con energía eléctrica, como muestra el documento ES 2 326 058 A1 , con conceptos de climatización de terrazas exteriores análogo al empleado en las estufas de gas.  Thus, there are several existing patents that describe this type of stove. For example, document ES 1 044 127 U shows an outdoor gas heater owned by the home located at a high point thereof, such that it radiates the heat generated therein over a wide radius. In addition, patents are also found with claims of specific characteristics thereof, such as for example the document ES 1 073 802 U which describes an outdoor gas heater that includes a payment system for its use, or the document ES 2 167 913 T3 which describes a heating device for umbrella type terrace. In addition, outdoor stoves powered by electric power are also described, as shown in document ES 2 326 058 A1, with concepts of outdoor terrace air conditioning similar to that used in gas stoves.
Sin embargo, todas las estufas para exteriores alimentadas por gas o electricidad presentan una doble problemática relacionada precisamente con estas fuentes de alimentación: el impacto medioambiental (huella de carbono) derivado de la generación de la energía (en particular la eléctrica) y el impacto económico derivado del precio de la energía consumida. However, all outdoor stoves powered by gas or electricity have a double problem related precisely to these power supplies: environmental impact (carbon footprint) derived from the generation of energy (particularly electricity) and the economic impact derived from the price of energy consumed.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención propone una solución a la problemática medioambiental y económica que muestran las actuales estufas de exteriores a través del uso de pellets de biomasa como fuente de alimentación, al ser dichas pellets una energía renovable, de coste energético inferior a las fuentes de energía utilizadas hasta la fecha (gas y electricidad). Esto es debido a la naturaleza de los pellets, los cuales son considerados como combustible limpio y ecológico, con un coste medioambiental neutro al haber captado previamente los gases que va a generar en su combustión y permitiendo el empleo de las cenizas creadas como abono al ser totalmente biodegradables. En cuanto al impacto económico, los actuales precios del mercado energético nos muestran que el coste del empleo de pellets para generar energía (€/KWh) representa la mitad del que muestran las energía gas de propano y butano, y casi cuatro veces más económico que el que presenta el empleo de electricidad. The present invention proposes a solution to the environmental and economic problems that current outdoor stoves show through the use of biomass pellets as a power source, since said pellets are a renewable energy, of lower energy cost than the energy sources used to date (gas and electricity). This is due to the nature of the pellets, which are considered as clean and ecological fuel, with a neutral environmental cost by having previously captured the gases that will be generated in their combustion and allowing the use of ashes created as fertilizer to be totally biodegradable. Regarding the economic impact, the current energy market prices show us that the cost of using pellets to generate energy (€ / KWh) represents half of that shown by propane and butane gas, and almost four times cheaper than the one that presents the use of electricity.

En otro aspecto de la invención el aparato cuenta con al menos un acceso directo a el al menos un depósito de pellets para llevar a cabo su llenado. Este acceso directo facilita la tarea de llenado al personal autorizado, acortando con ello tiempos innecesarios en dicho proceso. En otro aspecto de la invención el aparato calefactor exterior cuenta con al menos un sistema de regulación que controle la salida de los pellets del al menos un depósito hacia al menos un hogar de combustión. Gracias a este sistema se podrá controlar de manera automática la cantidad de calor a emitir al ambiente en función de la cantidad de pellets incorporada al hogar de combustión. De esta manera, se puede conseguir una temperatura de climatización acorde a las demandas térmicas exteriores sin necesidad de despilfarro de energía y, por tanto, económico.  In another aspect of the invention, the apparatus has at least one direct access to the at least one pellet tank for filling. This direct access facilitates the task of filling authorized personnel, thereby shortening unnecessary time in said process.
