Definitions

  • a preheating tube installed to traverse an upper portion of a burner bowl has a dual structure so that a gas tube with small diameter is inserted into the preheating tube as a gas passage and an inhaling member is put into a space out of the preheating tube.

Accordingly, butane gas is injected in advance at an ignition stage so as to be injected and combusted through a nozzle of a main valve via the gas tube in the dual preheating tube after passing through an upper end of the fuel tank, thereby eliminating a conventional problem of incomplete combustion of gasoline caused by preheating.
  • a portable stove is a device frequently used for cooking in outdoor leisure activities such as mountain climbing, fishing or the like.
  • the stove is in brief classified into petroleum or gasoline stoves using atomized or vaporized liquid fuel, and gas stoves using liquefied gas fuel (butane).
  • the petroleum stove needs a preparation tool for preheating such as a preheating torch and alcohol, which is so cumbersome.
  • the petroleum is gradually used not so often.
  • the gas stove using butane as a fuel is recently widely used owing to convenience in carriage and manipulation.
  • the gas stove gives small energy output in comparison to volume of liquefied butane, and its flame is easily extinguished by wind.

  • fuel is not sprayed in below-zero temperature, so it can be hardly used in the winter unless a separate heating device is attached thereto.
  • propane gas is not suitable for a portable stove since it requires very strong container to endure pressure due to its too low evaporation point (- 40 °C).
  • gasoline stove does not need any separate tool for preheating since gasoline itself gives the preheating action, and also the gasoline stove gives better heating power than the gas stove.

  • the gasoline stove ensures easy ignition even in below-zero temperature or against the wind, so it is convenient to use.

  • butane gas is injected into the fuel tank in a region above gasoline so that the butane gas is combusted at an initial ignition stage, thereby eliminating the need of preheating that results from incomplete combustion of gasoline at an initial ignition stage in a conventional gasoline stove.
  • gasoline is continuously inhaled, vaporized and injected by means of vapor pressure in an upper portion of the fuel tank and osmotic pressure of the inhaling member without any pressuring work for the gasoline.
  • the present invention ensures the nozzle to be not easily separated but easily exchanged.
  • the gas discharge hole is formed downward at one side of the fuel injection hole, and the inhaling member is filled to a middle portion of the entire length of the preheating tube, so that the portable multi-fuel stove may have small and light structure.

Abstract

L'invention concerne un réchaud multicombustible sans pompe portable pouvant faire appel, conjointement, à de l'essence et du butane. Le butane est injecté au-dessus de l'essence dans le réservoir à combustible de sorte que ce butane soit brûlé lors de la phase d'allumage initiale, ce qui supprime la nécessité de réaliser un préchauffage résultant d'une combustion incomplète de l'essence en phase d'allumage initiale, nécessité inhérente à un réchaud à essence classique. Une fois qu'une certaine quantité de butane est brûlée, bien que le butane ne soit plus fourni, l'essence est aspirée, vaporisée et injectée de manière continue au moyen d'une pression de vapeur dans le réservoir à combustible et d'une pression osmotique de l'élément d'aspiration sans aucune opération de mise sous pression de l'essence. La buse n'est pas facilement séparée mais peut être facilement remplacée. L'orifice d'évacuation des gaz est formé vers le bas au niveau d'un côté de l'orifice d'injection de combustible. L'élément d'aspiration est rempli jusqu'à une partie intermédiaire de la longueur du tube de préchauffage de sorte que la structure du réchaud soit petite et légère.
