Definitions

  • the invention relates to a fire column for generating a vortex flame with an outer shell, a base, an air guide element and a fuel container.
  • the invention also relates to a fuel container for a fire column according to the invention.
  • fire columns of fire usually with a glass cylinder as the outer shell, the flame is set in motion with turbulent air, so that the "tornado-like" appearance creates a special visual attraction for the viewer.
  • fire columns are also suitable for use indoors and are primarily used for decoration, but also for the relaxation of the residents, as is often attributed to open fireplaces (or simulated open fires on monitors).
  • fire pillars are used in outdoor areas, for example on terraces, whereby they can also serve as light and heat sources on colder evenings.
  • a fire column which includes a fuel container for bioethanol and similar fuels.
  • the fuel tank is open at the top.
  • the fuel contained in the fuel container can burn producing a large, tall and spiraling flame.
  • the object of the invention is therefore to ensure a good burning process for columns of fire.
  • a pillar of fire basically serves decorative purposes. A special suitability for heating food or liquids is not required.
  • a fire column is portable and suitable for indoor or outdoor use.
  • Whirling flame refers to a flame that is rotated by air and is therefore spiral-shaped.
  • Outer Shell means the outer shell of a Pillar of Fire.
  • This outer shell is open at the top and bottom, but in particular forms an at least predominantly closed barrier to horizontal exchange with the air outside the shell over the entire area of the flame.
  • the outer shell typically has no openings through which air can flow over the area of the flame.
  • the outer shell then forms a completely closed barrier in the horizontal.
  • the shell can be transparent or translucent or can comprise transparent or translucent sections.
  • the outer shell consists of one piece and has been manufactured in one work step in order to keep the number of parts low.
  • An outer shell can be designed, for example, as a round glass cylinder or as a metal cylinder with glazed openings. In addition, almost any other shape is possible, whether angular, bulbous, conical, concave, stretched, compressed, symmetrical, asymmetrical or irregular. However, a circular diameter is preferable if a particularly even flame pattern is to be generated.
  • the outer shell can be made of any non-combustible material or mix of materials including clear, cut, tinted or tinted glass, smoked glass, metal or ceramic.
  • Base refers to a block located in the lower area of the fire column, which is regularly used for installation, to hold the fuel container and/or as a holder for the outer shell.
  • the base can be designed as a pedestal or can include a pedestal, a ground spike or some other fastening option.
  • the base can be connected or connected to a stand or a ground spike.
  • the base consists of one piece and has been manufactured in one work step in order to keep the number of parts low.
  • the base itself can function as a fuel tank or a fuel tank can be integrated in the base.
  • the base may be suitable for fully or partially accommodating or for the direct or indirect connection of a fuel tank.
  • Most of the outer shell can be positioned above the base.
  • a lower end of the outer shell can partially or completely enclose the base laterally.
  • Air guiding element designates a structural element for deflecting an air flow thermally generated by the flame, which causes the flame to rotate.
  • a vortex flame is created.
  • the vortex flame resembles the shape of a spiral.
  • an air guiding element can be designed as a straight or curved, closed or semi-open duct.
  • An air guide element can comprise a flat or curved surface.
  • An air guide element can be made from sheet metal.
  • the air directing element can interact with other elements of the fire column in order to direct air in such a way that a vortex flame can form.
  • the additional element can be the outer shell and/or the base.
  • an air guiding element can be integrated in the base or the outer shell or attached to them. In the erected state, the air guiding element preferably encloses an acute angle with the horizontal. It is therefore only slightly tilted in relation to the horizontal.
  • Fuel container refers to a container for the safe storage and safe removal of fuel, especially during the burning process.
  • Fuel containers can be designed in particular as canisters, cartridges, bottles or cylinders made from materials such as glass, ceramics, sheet metal, other metals or suitable plastics.
  • the fuel container can be embodied as a closed container without the possibility of being refilled, or it can comprise a refill opening which can usually be closed again.
  • the fuel container is preferably made of metal. The fuel container is then reliably fireproof and can be manufactured in a technically simple manner.
  • the fuel container may include a resealable refill port.
  • the resealable refill port may be the port through which the wick passes. The wick can then be pulled out of the fuel container. In the The fuel tank can then be filled with fuel. After filling, the wick can be reinserted into the opening.
  • the upper end of the fuel container is at least mostly closed.
  • the upper end of the fuel container may be a top wall of the fuel container which cannot be removed and has no or almost no openings.
  • the upper end of the fuel container may be a detachable fuel container cover which has no or almost no openings.
  • Fuel is a chemical substance whose stored energy is released through combustion.
  • ethanol, alcohol, petrol, oil or wax are fuels.
  • a fuel can be in liquid form, in solid form, as a gel or as a paste.
  • Wick refers to a material which is suitable for supplying liquid fuel to the combustion zone against the force of gravity with the aid of capillary forces.
  • a wick can be spun, braided or woven, filament-like or flat.
  • a wick can consist of vegetable, animal, chemical or other fibers.
  • a wick can be made of hemp, coconut, sisal, cotton, glass, metal and/or aramid, for example.
  • the fibers of the wick consist of refractory materials.
  • Refractory materials are materials which withstand the flame of the fire column, in particular neither burn nor melt, such as glass, minerals, metal or aramid.
  • materials with a service temperature of over 600°C are refractory materials.
  • wicks based on refractory materials such as wicks made of glass fiber, aramid or metal, offer the advantage of improved length stability. Such wicks therefore reliably always protrude the same distance from the surface of the fuel container. This further contributes to obtaining a clearly visible vortex flame in a reproducible manner.
  • a limiting element limits the length of the wick above the fuel container.
  • Limiting element means a refractory element which limits the protrusion of a wick above the top of the fuel container.
  • the limiting element is preferably made of metal so that it can be easily manufactured.
  • Limiting the length of the wick above the top of the fuel container prevents the wick from protruding excessively from the top of the fuel container. If the wick reaches the delimiting element, it can thereby be ensured that the wick protrudes in a defined manner in relation to the upper side of the fuel container. Below the upper end of the fuel container, ie inside the fuel container, the length of the wick is limited by the closed lower end of the fuel container. This ensures that the flame is neither too small nor too large.
  • Delimiting elements can be designed, for example, as pins, brackets, nets or braids. Limiting elements can in particular be fastened to the fuel tank itself, to the cover of the fuel tank, to the outer shell or to the base. They can pass over the ends of the wicks or otherwise prevent the wicks from moving, particularly in the vertical direction.
  • a delimiting element can be made of refractory materials, in particular metal.
  • the upper end of the fuel container is a detachable cover of the fuel container which has no or almost no openings.
  • the lid is preferably connectable to the remainder of the fuel container in such a way that the lid cannot accidentally come loose.
  • a lid is a nearly or completely airtight and dustproof closure of a container.
  • a lid can be large or small compared to the cross-section of the rest of the fuel container.
  • the lid can be round, oval or square.
  • a lid can be completely detachable from the container for opening or can remain mechanically connected to the container, for example by a folding mechanism or a safety cable. It may be a screw-on cap or a cap that can be connected to the remainder of the fuel container by means of clips or snaps in such a way that the cap cannot accidentally come loose.
  • the lid or container may include one or more seals to prevent leakage.
  • An annular flat seal can be provided as the seal. Such a seal can be used for particularly reliable sealing.
  • the flat seal can be held in a form-fitting manner on the cover using brackets.
  • the brackets may include flexible tabs that allow brackets to be held in a form-fitting manner.
  • a detachable cover as the upper end of the fuel container allows you to easily check the fill level of the fuel container before igniting the fire column and to refill fuel easily. This helps ensure that a highly visible swirl flame is always maintained.
  • a gripping element enables the cover to be gripped securely, in particular in order to detach the cover from the fuel container or to lift the fuel container as a whole.
  • a grip element can be designed in particular as a suitable shape of the cover or as a suitably shaped ring or bracket connected to the cover. The ability to safely lift the lid with a handle reduces the risk of damaging the wicks. This helps maintain a highly visible swirl flame.
  • the handle or the handle element is at the same time a delimiting element for at least one wick in order to minimize the number of parts.
  • the handle is preferably in one piece in order to be able to keep the production costs low.
  • the wick is positioned at the upper end of the fuel container in the middle of the cross-section of the inner wall of the outer shell. Such a central positioning of the wick makes it easy to create good air flow conditions around the entire flame. This helps maintain a highly visible swirl flame.
  • a plurality of wicks pass through the closed top of the fuel container.
  • a plurality of wicks makes better use of the available surface area for generating a vortex flame.
  • heat can also be generated immediately in the edge area. This ensures, among other things, that a clearly visible vortex flame can develop particularly quickly after ignition.
  • a plurality of wicks of the fuel container are evenly distributed along an imaginary circle on the upper end of the fuel container.
  • Such an evenly distributed arrangement along an imaginary circle allows the interaction of the respective flames to be as uniform as possible to produce a single large flame and to produce good air flow conditions around this flame in a simple manner. Both contribute to obtaining a clearly visible swirling flame, which is quickly visible after lighting.
  • the pressure equalization opening is just large enough to ensure pressure equalization inside the fuel tank if the fuel level drops during the combustion process. On the other hand, the opening also allows excess pressure to escape, so that the wicks always deliver the same amount and the fuel is not forced through the wick by the excess pressure
  • such a vent is located near each wick that passes through the top of the fuel container. This ensures the undisturbed supply of fuel to the flame and thus helps to obtain a well visible vortex flame.
  • the outer wall of the base essentially has the shape of a cylinder.
  • a cylindrical shape of the outer wall of the base is suitable for supporting the deflection of air flowing in at the lower end of the fire column into a rotating stream of air in a streamlined manner. This favors the supply of suitable fresh air currents required to generate a vortex flame and thus helps to obtain a clearly visible vortex flame.
  • At least one air guiding element encircles the outer wall of the base in a helical manner.
  • a helical design of at least one air guiding element around the outer wall of the base is suitable for supporting the deflection of air flowing in at the lower end of the fire column into a rotating air stream in a streamlined manner. This favors the supply of suitable fresh air currents required to generate a vortex flame and thus helps to obtain a clearly visible vortex flame.
  • a support element is a constructive element onto which the outer cover can be placed vertically from above and which limits the movement of the outer cover, alone or in combination with other support elements, in particular in the vertical direction.
  • a support element can be, for example, a ring, a ring, a flat surface, a pin, a bolt, a hook or a spring element.
  • a support element can protrude beyond the cross-section of the inner wall of the outer shell.
  • a support element, in combination with a suitable configuration of the inner wall of the outer shell, such as a groove, a projection, a ring or a hook, can limit the movement of the outer shell in the vertical direction.
  • the column of fire comprises at least three support elements, since reliable support is thereby achieved with the smallest possible number of parts.
  • a support element is preferably designed as a bolt or pin in order to keep the cost of materials low.
  • the lower end of the outer shell resting in the area of the lower third of the outer wall of the base allows a sufficient amount of fresh air to flow in at the lower end of the fire column, particularly at the lower end of the base, as well as the streamlined redirection of the inflowing air in the interaction of the outer wall of the base, the air guide element and the inner wall the outer shell. This favors the supply of suitable fresh air currents required to generate a vortex flame and thus helps to obtain a clearly visible vortex flame.
  • a support element can protrude horizontally from the base wall and protrude beyond the cross section of the inner wall of the outer shell, in order to enable a particularly good supply of air to the flame at the same time.
  • the fire column according to the invention comprises an extinguishing cover.
  • An extinguishing cover is a cover for extinguishing the flame.
  • a cover to extinguish the flame reduces the fresh air supply to the flame so much that the flame goes out after a short time, usually after a few seconds at the latest.
  • Such a cover allows the deletion process to be carried out quickly and precisely at the desired time.
  • a subsequent burning process is not adversely affected. This therefore helps to always obtain a clearly visible vortex flame, both right up to the end of an ongoing and during a subsequent combustion process.
  • the invention also relates to a fuel container for a fire column according to the invention.
  • the fuel container can be designed as previously described.
  • the fuel container has a closed body and is at least mostly closed at the upper end. At the top there can only be one or more openings for the passage of wicks and one or more ventilation openings.
  • the ventilation openings are generally smaller than the openings for the passage of the wicks.
  • the fuel tank then has no further openings. Passes through the top of the fuel tank at least a wick. There is a limiter that limits the length of the wick above the fuel container.
  • the wick preferably comprises refractory fibres, in particular glass fibres.
  • the delimiting element serving as a gripping element can be made of one or more metal wires. Metal wires of the delimiting element can be welded to one another.
  • a plurality of wicks preferably pass through the closed top of the fuel container.
  • wicks can be covered by a net, for example.
  • the net can be made of metal.
  • a covering with holes or a covering net makes it easier and faster for the wick to become saturated with fuel.
  • a largely constant flame height can also be achieved by a cover with holes or by an enveloping net.
  • a cover or an enveloping net provide mechanical protection.
  • FIG. 15 shows a further embodiment of a fuel container with tubes for wicks.
  • the upper side 5a is essentially slightly funnel-shaped and opens into a centrally arranged cylindrical tube piece 5c. This allows fuel to be poured onto the top 5a, which can then be filled into the fuel container 5 through the pipe section 15 when the wick 6 has been removed as shown in FIG. This makes it particularly easy to refill the fuel tank 5 with fuel.
