    [0002] Portable kitchen
    [0003]
    [0004] Technical field of the invention
    [0005] The present invention relates to a portable kitchen designed for the heating of prepared foods and that by its shape and size is perfect to be transported.
    [0006]
    [0007] Antecedents of the Invention
    [0008] At present there are many portable kitchens of small size for use in the field or similar, all of them very complex or requiring to be armed.
    [0009]
    [0010] As an example of the state of the art we can mention the following reference documents ES1009097U, ES1015462U, ES1013099U and ES1042494U.
    [0011]
    [0012] The reference document ES1009097U defines a camping stove that is the most similar to the one that is presented since it uses liquid fuels and is small in size but its configuration and operation are totally different.
    [0013]
    [0014] Reference document ES1015462U proposes a stove for culinary use. Its size is not very small and is ready to cook. The invention presented here is exclusively for the heating of food and not for cooking.
    [0015]
    [0016] In the reference document ES1013099U a portable folding burner stove is defined, which can be transported because it has the ability to fold and unfold. The present invention does not have said capacity. In addition, the size and shape between the two inventions are totally different.
    [0017]
    [0018] With regard to document ES1042494U, this defines a portable gas cooker with a built-in cylinder by means of a special interlock. The size is much larger than the presented invention and for its use incorporates a gas cylinder. In the present case, the fuel used is liquid.
    [0019]
    [0020] All these solutions raised in the state of the art have in common that they have been developed to be able to transport themselves comfortably and to be able to heat the food in any place. But, despite that, none of them has the advantage of the small size of the present invention that makes it the most practical and comfortable that exists. In addition, it is the only existing one that has a double wall, which serves as a safety element since spillage is prevented in the event of overturning or rolling.
    [0021]
    [0022] Description of the invention
    [0023] The portable micro-kitchen of the invention is of the type that uses a fluid as fuel and has as a main novelty the fact that it comprises an outer tubular body, closed by its lower base, in which an inner tubular body is housed forming between both a double wall that determines a chamber in which the fuel is housed.
    [0024]
    [0025] The chamber formed by both tubular bodies is closed at its mouth by means of an annular element, which is provided with holes, preferably equidistant, so that when the fuel is burned, said orifices allow the passage of the fire to the outside, with which when placing a vessel its heating occurs. Under the annular element is placed a heat diffuser, which is hidden by the annular element, and which is constituted by a strip of corrugated sheet, arranged vertically and forming an annular configuration, complementary to the shape of the chamber formed by the bodies Tubular interior and exterior. The described configuration of the heat diffuser optimizes the evaporation of the fuel, by distributing it by means of the different corrugations and in addition it allows to realize the correct distribution by the equidistant orifices of the annular element, so that a uniform fire is guaranteed simulating the pattern of a fogon.
    [0026]
    [0027] In the preferred embodiment of the invention, the camera is filled with an insulator, which is soaked with the fuel, so that its combustion is regulated, providing a lower fuel consumption. The insulator used is fiberglass, cotton or a combination of both, to provide a good regulation of the combustion of the liquid fuel.
    [0028]
    [0029] In addition, the invention comprises a lid for closing the upper base of the outer and inner tubular bodies, which is used to cover the device when the kitchen is not in use, providing a means of protecting the device during storage and transportation.
    [0030]
    [0031] In the preferred embodiment of the invention, the outer tubular body and the inner tubular body have a cylindrical configuration, where the outer tubular body has, preferably a height of 6 cm and a diameter of 6 cm. The invention provides that the outer tubular body and the inner tubular body can adopt any other tubular configuration, which allows the formation of a chamber in which the fuel and the insulator are housed, and which is sealed by an annular element under which includes a heat diffuser, such as a polygonal, oval section configuration, etc.
    [0032]
    [0033] To light the micro-kitchen, the fuel is heated beforehand so that it starts to evaporate and ignite. The fuel, for example, can be denatured alcohol.
    [0034]
    [0035] The small size of the kitchen is intended to reduce the time of heating the fuel and the amount that is needed fuel, but is effective enough to meet its objective.
    [0036]
    [0037] The micro kitchen could be bigger but it would not improve in effectiveness and it would have the disadvantages of being heavier and more bulky for its transportation, need more liquid as fuel and need more time for its heating. The invention presented fits in a pocket.
    [0038]
    [0039] The different parts described are made of aluminum, as it is the perfect material for its low price, light weight and being a good heat diffuser. Any other material that shows good heat transmission could also be used.
    [0040]
    [0041] The alcohol is poured to about 1/3 of the total height, and is absorbed by the insulator, with a small amount remaining in the bottom for initial heating. When you turn on this alcohol, it heats the camera causing evaporation. When a certain amount is in a state of steam and begins to come out through the holes, an external flame is ignited and due to oxygen consumption causes the internal flame to extinguish. Consequently, the heat diffuser improves the quality of the steam and equalizes the outlet temperature. A fuel charge allows approximately between 30 and 45 minutes of ignition. Another advantage of soaking the fuel in the insulation is to avoid serious accidents in the event of overturning or rolling. If you dump or roll almost nothing of the fuel comes out of the micro kitchen when soaked in cotton.
    [0042]
    [0043] Brief description of the drawings
    [0044] In order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, a series of drawings is provided as an integral part of said description, where, with an illustrative and non-limiting character, represented the following:

    [0049] Figure number 4: Vertical section of the kitchen,
    [0050] Figure number 5: Explosive perspective of the micro kitchen, according to what is represented in the previous figures.
    [0051] Figure number 6: Perspective of the micro kitchen, of the previous figures, with the lid on.
    [0052]
    [0053] DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    [0054] In view of the figures provided, it can be seen as in a preferred embodiment of the invention, the micro-kitchen designed for heating prepared foods, which is proposed here, comprises two tubular bodies, inserted one in the other; that is to say, an outer tubular body (4) and an inner tubular body (2) between which a chamber (6) is established, which is filled with an insulator (5), for example fiberglass or cotton, which is soak with a fluid fuel, such as alcohol. The insulator (5) has the advantage of regulating the combustion, providing a lower fuel consumption.
    [0055]
    [0056] In the exemplary embodiment, the outer tubular body preferably has a height of 6 cm and a diameter of 6 cm. This small size allows to reduce the heating time of the fuel and the necessary amount of fuel, and is sufficiently effective to meet the goal of food heating.
    [0057]
    [0058] The micro kitchen could be bigger but it would not improve in effectiveness and it would have the disadvantages of being heavier and more bulky for its transportation, need more liquid as fuel and need more time for its heating. The invention presented fits in a pocket.
    [0059] In the embodiment example of the invention, the tubular bodies have a cylindrical configuration, but as already mentioned, they could adopt any other configuration.
    [0060]
    [0061] The upper part of the chamber (6), is closed by an annular element (8) that is equipped with a plurality of holes (7) equidistant and of the same size, which when burning the fuel allow the passage of fire to the exterior in a manner uniform simulating the pattern of a fogon. Under the annular element (8) it comprises a heat diffuser (3), which is constituted by a strip of corrugated sheet, arranged vertically and forming an annular configuration, complementary to the shape of the chamber (6).
    [0062]
    [0063] The upper base of the tubular bodies (2 and 4) is sealed by a cover (1) for closing and protecting the device when it is not used, providing a means of protecting the device during storage and transportation.
    [0064]
    [0065] As previously mentioned, the alcohol is poured to approximately 1/3 of the total height, and is absorbed by the insulator, with a small amount remaining in the bottom for initial heating. When you turn on this alcohol, it heats the camera causing evaporation. When a certain amount is in a state of steam and begins to come out through the holes, an external flame is ignited and due to oxygen consumption causes the internal flame to extinguish. The arrangement of the vertical corrugations in the chamber (6) causes the steam and the generated heat to be evenly distributed to the holes (7) of the annular element (8), which makes it possible to equalize the outlet temperature, so that it is guaranteed a uniform fire simulating the pattern of a fogon.
