Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0034] For a better understanding of what has been explained above, some drawings are included in which, schematically and only by way of a non-limiting example, a practical case of embodiment is represented.

[0035] FIG. 1 is a schematic elevation view of the outdoor stove according to the present invention.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0036] As shown in FIG. 1, the outdoor stove according to the present invention comprises a base 1, which is preferably square in shape, but could be of any other suitable shape, metal or any other type of material covering the intended function.

[0037] This base 1 comprises supports or wheels 4, which facilitate its movement. The weight, design, material used and dimensions of this base 1 are such as to ensure the stability, robustness, and weather resistance of the entire stove assembly.

[0038] The base 1 houses a fuel tank 5, which prevents fuel spillage in the event of an accident. This fuel is advantageously a material that complies with the regulations for outdoor stoves, e.g., ethanol.

[0039] The base 1 also comprises a flame intensity regulator 3, which regulator is preferably pivoting, and a refueling pipe 7 provided with a plug which is directed towards the outside of the base 1, through which the tank 5 is filled, even when the stove is in operation. The base 1 also includes a burner 12 which generates a flame, which exits through an outlet 9, preferably in a position centered on said base 1.

[0040] According to the embodiment shown, the base 1 has a truncated cone shape, and the refueling pipe 7 is preferably positioned on the side wall of the truncated cone shape, separated from the flame, which is located in the upper central part of the base 1.

[0041] The function of the regulator 3 is to regulate the intensity of the flame and extinguishing the flame from the outside.

[0042] One or more openings 2 are provided in the upper part of the base 1 to allow ambient air to enter the stove.

[0043] On the base 1 there is a combustion chamber 8 formed from a structure, for example, of metal or any other heat-resistant material, and fitted with shields, for example, of glass, this combustion chamber 8 channeling the hot air produced by the flame.

[0044] The upper part of the base 1, in contact with the combustion chamber 8, defines a surface 13 such that the flame exit surface 9 occupies between 5% and 20% of the surface 13 of the base 1, in particular, for example, the flame exit surface 9 occupies between 9% and 14% of the surface 13 of the base 1.

[0045] In addition, the volume of the combustion chamber 8 is preferably between 0.10 and 0.20 cubic meters, in particular between 0.11 and 0.18 cubic meters, depending on its surface area and height.

[0046] Inside the combustion chamber 8, the air captured through the opening(s) 2 comes into contact with the flame produced by the burner.

[0047] The glass protection of the combustion chamber 8 allows a view of the flame produced by the burner. One part of the protection is advantageously practicable, to allow access to the interior of the combustion chamber 8 to be able to ignite the stove.

[0048] In the upper part of the stove there is a diffuser 10, whose mission is to channel all the hot air produced by the burner to the outside of the combustion chamber 8 through an outlet 11, and to smooth the exit of the hot air produced in the combustion chamber 8 to the outside.

[0049] Although reference has been made to a specific embodiment of the invention, it is obvious to a person skilled in the art that the outdoor stove described is susceptible to numerous variations and modifications, and that all the details mentioned can be replaced by technically equivalent ones, without departing from the scope of protection defined by the appended claims.
