- the present invention refers to a modular stove that runs on wood, specially designed for use and implementation in rural settings where there is no access to any other type of fuel.
- the invention comprises a basic module and four different extensions, which allow an initial installation to be made, and the other elements to be added later depending on the needs and requirements of each user.
- the stove in its basic module is illustrated in figure 1 and comprises at least the elements of: i) a folding casing (1); ⁇ I) a base tray (2) for the folding casing (1); iii) a plate (7); iv) a griddle of the griddle (8); v) an isolation chamber (3); vi) a combustion chamber (5); vii) a combustion chamber grill (6); and viii) an insulating material, which are described below:
- the folding casing (1), illustrated in figure 12, consists of a casing made in 4 pieces. This element constitutes the exterior part of the stove, and fulfills the function of containing the combustion chamber (5) and the thermal insulating material that lowers the outside temperature of the stove, and therefore mitigates heat losses from it to the surroundings.
- the base tray (2) for the folding casing (1) shown in Figure 13, is a removable tray that serves as the base or floor of the folding casing (1). This piece is located in the lower internal part of the folding casing (1).
- the iron (7), described by figure 17, consists of a plate that is located in the upper part of the folding casing (1) and fulfills the function of directing the heat produced towards the cooking vessels.
- the grill of the plate (8) illustrated in figure 18, consists of a metal ring in the shape of a cone with tabs in vertical position. This particular element is located in the upper part of the griddle (7), and fulfills the function of supporting the cooking vessels.
- the isolation chamber (3) corresponds to an arc-shaped piece, which forms a channel or wall around the combustion chamber (5) or elbow to be filled with an insulating material (4 ).
- This isolation chamber (3) fulfills the function of containing the main insulating material.
- the combustion chamber (5) defined by figure 15, consists of a cylindrical elbow. This element is located inside the folding casing, and it supports the combustion chamber grill (6), providing a front entrance, so that the firewood is inserted into the stove through said entrance and is deposited on said grill. Thus, when the wood combustion process begins, the combustion chamber (5) directs all the heat towards the upper part, where the grill of the iron that supports the cooking vessels is located.
- this element contributes to increasing the thermal efficiency of the stove, considering that it not only directs the heat directly towards the cooking container, but it is also surrounded by the insulating material and the insulation chamber that contains it. which prevents heat loss from being generated in the lateral directions.
- the combustion chamber grill (6) illustrated in Figure 16, consists of a support for firewood located inside the elbow through the front inlet.
- this element supports firewood and / or charcoal in such a way that it burns completely.
- the insulating material (4) placed in the channel or wall around the combustion chamber (5), preferably consists of ash or pumice, however, other insulating materials such as expanded perlite can be used.
- the basic module described in the previous point can be added the elements of: i) one or more frames (9) for the stove; ⁇ I) vertical supports (10) for the stove; and ii) two counters or a shelf tray (11), which consist of:
- the frame (9) for the stove, shown in Figure 19, consists of a square box that fulfills the function of supporting the folding casing ( 1), the iron (7) and the shelves or trays (11).
- the vertical supports (10) for the stove consist of elongated structural elements by means of which it is possible to assemble one or more frames (9) to the stove, give it the ideal height for cooking and provide a reliable rigid support .
- the shelves and / or shelf shelves (11), shown in Figure 21, consist of sheets that are generally located in the upper right part of the stove. Thus, it fulfills the function of providing a additional space for food preparation before or after cooking them.
- the basic module with the particular configuration of the additional elements of this first extension provides a stove in which it is also possible to cook standing up to an economically correct height. Also, this extension allows to have an additional space to prepare food and a compartment. However, a possible further extension is provided as part of the invention which will be described below. 5.3 Description of extension two
- An additional module can be added to the stove resulting from the previous expansion by including the elements of: i) A folding casing (1); ⁇ I) A base tray (2) for the folding housing (1); i ⁇ ) a plate (7); iv) a griddle of the griddle (8); iv) an isolation chamber (3); v) a combustion chamber (5); vi) a combustion chamber grill (6); and vii) an insulating material.
- a folding casing (1) ⁇ I) A base tray (2) for the folding housing (1); i ⁇ ) a plate (7); iv) a griddle of the griddle (8); iv) an isolation chamber (3); v) a combustion chamber (5); vi) a combustion chamber grill (6); and vii) an insulating material.
- this expansion corresponds to the addition of a second basic module, so the elements included are the same ones used and described previously in point 5.1 referring to the construction of the base stove.
- the addition of this segment to the first expansion of the stove, shown in figure 2 is carried out following the procedure shown in figure 9.
- the plate with two reducing rings (14), shown in Figure 24, corresponds to a flat element with two cutouts in the form of two rings or reducing rings, which is located on top of the second plate tray (12) in the left side and fulfills the function of supporting the cooking container, creating a space where cooking containers of different sizes can be inserted to receive the heat and flame produced and at the same time allow the flow of hot air.
- the plate with a reducing ring and chimney support (15) of figure 25, is a flat element with a ring-shaped cutout and a square hole, which is located above the second plate tray (12) in the right side and fulfills the function of supporting both a second cooking container and supporting the chimney (16).
- the second plate tray (12), illustrated in figure 22, consists of a sheet with a hole, which is located above the upper frame and fulfills the function of supporting the two plates, allowing the hot air to be contained and making it flow correctly into the chimney (16).
- the chimney (16), shown in figure 26, corresponds to any type of duct that directs the smoke generated by the combustion of the firewood to a place far from the stove.
- a tray with oven (13) is added, such as the one illustrated in figure 23, which consists of a module that includes a flat section with a hole on the left side and a compartment on the right side. This element is placed in place of the second griddle tray (12) and allows, in addition to cooking, baking food.
- the configuration of the stove that this extension contemplates can be seen in figure 5.
