Description

The utility model relates to tourist equipment designed for space heating, mobile baths and cooking. The stove can be used to heat various tents and small spaces, subject to fire safety regulations. The stove is designed to use any wood, wood chips or fuel briquettes as fuel.

Known universal stove "Hunting", containing a body with a combustion chamber in the interior, a combustion chamber door with holes for air supply and a damper, a chimney pipe on the upper base of the body, a hob, a hinged lid, folding legs. The cover is located on the upper base of the furnace body and replaces part of the upper base and part of the side walls. The lid is equipped with hinges through which it is fixed on the upper base of the furnace. The combustion chamber has stiffening ribs for installing skewers, a grill grate or a charcoal grill. Folding legs are located along the long part of the furnace, have a solid plane (see US Pat. RF No. 2713539, F24B 1/02, F24C 1/16, A47J 37/07).

A disadvantage of the known furnace is its low efficiency due to the leaky housing, low heat capacity, while at the same time it is impossible to ensure compact storage and transportation in disassembled form.

The closest analogue to the claimed utility model is a vaulted sauna stove, containing a body with a combustion chamber in the internal space, with a door and a partition, an ash pan with an ash door, a hood combined with a gas manifold, and an enclosing casing-convector with convection holes. A shielding wall is located outside the furnace body. The grate and the ash pan located under it with an ash door are located in the lower part of the common body. The cap and the gas collector are separated by a divider, which is formed by a continuation of the chimney outlet, in particular, by the continuation of the branch pipe for the chimney, there is a heater outside the gas collector (see RF patent No. 142846, F24C1 / 00).

The disadvantage of this furnace is the difficulty of setting the intensity of combustion in the absence of the ability to regulate the air flow through the ash pan, while at the same time it is impossible to compactly store and transport it in disassembled form.

The technical problem of the known technical solutions lies in the low heat capacity and the difficulty of adjusting the intensity of combustion, while the impossibility of compact storage and transportation in disassembled form.

The essence of the claimed utility model lies in the fact that the furnace contains a combustion chamber, a chimney pipe, an ash pan placed under the combustion chamber, a grate located between the ash pan and the combustion chamber, and a heater. The stove is equipped with folding legs and a cooking surface located above the combustion chamber. The hob is a cover of the combustion chamber, which is made collapsible. The grate is removable and placed on the lid of the ash pan, which is also the bottom of the combustion chamber. The walls of the heater are made collapsible. The ashpit is a container with the possibility of placing in it a collapsible combustion chamber and walls of the heater for storing and transporting the stove.

The technical result achieved by the claimed utility model is to expand its functionality due to the detachable connection of the elements of the furnace, which at the same time allows compact storage and transportation of the furnace in disassembled form.

The essence of the claimed utility model is illustrated by drawings, where:

in fig. 1 schematically shows a general view of the furnace;

fig. 2 is a longitudinal section of FIG. 1;

in fig. 3 - oven operation modes: a) heating mode, b) cooking mode, c) barbecue mode, d) transportation mode.

The furnace consists of a flat horizontally located ash pan 1 of rectangular cross section, on which folding legs 2 are placed. Side walls 5 of the combustion chamber 6 of the oven are installed on the ash pan 1, on top of which there is a hob 7, which is simultaneously the cover of the combustion chamber 6. Between the ash pan 1 and the combustion chamber 6 there is a grate 8, which is made removable and placed on top of the cover of the ash pan 1, which is simultaneously with the bottom of the combustion chamber 6. Horizontal partitions 9 are installed inside the combustion chamber 6 to form a labyrinth of air flow. The hob 7 is equipped with a cover 10 and a chimney pipe 11 with a chimney 12 installed on it. The walls of the heater 13 are installed on the hob 7, inside which stones 14 are placed. from hot walls 5, which eliminates the possibility of burns. Details of the combustion chamber 6 and the walls of the heater 13 are collapsible. The ash pan 1 is a container with the possibility of placing collapsible parts in it: side walls 5 of the combustion chamber 6, cooking surface 7, partitions 9, walls of the heater 13 and protective screens 15 for storing and transporting the stove. Such a constructive implementation of the proposed device provides for the expansion of its functionality due to the detachable connection of the furnace parts, which at the same time allows you to compactly store and transport it in disassembled form. Detachable connections can be made according to the type, for example, "thorn-groove", "protrusion-slot", "hook-slot". The collapsible multifunctional oven has four operating modes: heating mode, cooking mode, barbecue mode, transport mode.

Assembly of the proposed device in the heating mode is as follows. The ash pan 1 is installed indoors on the unfolded legs 2. Then, a grate 8 is placed on the cover of the ash pan 1. Next, the side walls 5 of the combustion chamber 6, horizontal partitions 9 and the hob 7, which is simultaneously the cover of the combustion chamber 6. Then, along the perimeter of the side walls 5 of the chamber combustion 6, protective screens 15 are suspended. A chimney 12 is inserted into the pipe 11 of the chimney located on the hob 7. The walls of the heater 13 are installed on the hob 7, where stones 14 are placed in the formed space. Firewood is placed on the grate through the door 16 of the combustion chamber 6 8 and ignite them. Further, by means of a screw mechanism 4, the position of the end face 3 of the ash pan 1 is adjusted, thus adjusting the intensity of combustion. In this case, the end face 3 is simultaneously the door of the blower. Horizontal partitions 9 in the combustion chamber 6 form a labyrinth to retain hot air flows, and this heat is used to heat the side walls 5 of the combustion chamber 6, the cooking surface 7 and to heat the stones 14, which in turn warms the tents or other small rooms. Stones 14 are able to absorb heat and slowly release it into the environment, and also allows you to arrange a mobile bath. Stones 14 for the heater can be used both prepared in advance and found by tourists at the parking lot.

In the cooking mode, the oven is assembled in the same way as described above, but without installing the walls of the heater 13 with stones 14 on the hob 7 of the oven. Cooking in the dishes is carried out on the hob 7, where, if necessary, the cover 10 is removed.

In the brazier mode, the ash pan 1 is installed on a horizontal surface by means of the unfolded legs 2. Then, a grate 8 is placed on top of the cover of the ash pan 1. Next, the walls of the heater 13 are installed on the ash pan 1, which in this mode are the walls of the brazier. Moreover, grooves for installing skewers can be made in the walls of the heater.

In the transportation mode, the furnace parts are disassembled: the side walls 5 of the combustion chamber 6, the hob 7, the horizontal partitions 9, the walls of the heater 13 and the protective screens 15. Next, the legs 2 placed on the ash pan 1 are folded. Now all the parts are placed inside the ash pan 1. First of all the most dimensional parts, then compactly stack the rest. Lastly, the end 3 of the ash pan is installed in its place and tightened by the closing mechanism 4. The chimney 12 can be made in the form of several sections; it is folded separately for transportation and storage. Stones 14 are also placed in a separate bag for transportation or left at the place of use. The detachable connection of the oven parts allows you to quickly and conveniently assemble and disassemble the oven, while all the parts are placed in a compact ash pan body.

Thus, the claimed utility model provides for the expansion of the functionality of the furnace due to the detachable connection of the furnace parts, which at the same time allows compact storage and transportation of it in disassembled form.
