  • Appliances that use gas are highly polluting and, for this reason, they are already prohibited or have an announced expiration date in all the countries of the European Union.
  • the electrical elements also do not comply with the literal nature of this regulation due to the fact that there are thermal and nuclear power plants, with which, and in origin, the energy produced is not renewable or sustainable and is also polluting.
  • an objective of the present invention is to provide an outdoor stove that heats the environment by means of an air convection system in a channeled, controlled and adjustable way, which allows the use of fuels from authorized non-conventional energies, these being sustainable, renewable and non-polluting energies, and that also optimize their performance and consumption, also avoiding possible burns due to physical contact.
  • Another objective of the outdoor stove according to the present invention is to be able to refuel it while it is in operation, without the need to stop its operation.
  • the outdoor stove according to the present invention comprises:
  • the stove comprises a base on which the fuel tank and the burner are arranged, said base comprising a fuel refueling pipe in communication with the fuel tank, said pipe being separated from the flame generated by the burner .
  • said refueling pipe comprises a removable cap.

  • Other types of relevant factors that have been foreseen are those related to safety and that are basically summarized in two aspects: control of the fuel in the event of the stove tipping over by accident, and control of the maximum attainable temperature in the parts external, which in no case can be a cause of burns for its users.
  • the autonomy of the tank has been another factor taken into account, contemplating maximum autonomy, since these stoves are basically designed to be used in open or semi-closed spaces in public places, such as cafeterias, restaurants, etc., and it is important to minimize maximum tank refueling operations.
  • the design of the tank allows it to be refueled even when it is in operation, since as it is external to the combustion chamber that contains the flame, there is no possibility of the burner flame coming into contact with the refilling point, which allows their autonomy is not limited to a certain capacity.
