Description

The utility model relates to tourist equipment designed for cooking and heating in camping and extreme conditions. The stove can be used to heat tents and small dwellings, subject to fire safety regulations.

The universal oven "Hunting" is known from the prior art (RF patent No. 2713539, published on February 5, 2020 under the headings of the IPC F24B1 / 02, F24C1 / 16, A47J37 / 07). SUBSTANCE: universal furnace contains a body with a firebox in the inner space, a chimney branch pipe on the upper base of the body, an air supply window, a hinged lid, and 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 upper rectangular base of the cover replaces part of the upper base of the furnace, the L-shaped side walls replace part of the side walls of the furnace, the front side wall replaces part of the front side of the furnace. The lid is equipped with hinges through which it is fixed on the upper base of the furnace. The firebox has stiffening ribs for installing skewers, a grill grate or a charcoal grill. The legs are folding and located along the long part of the furnace, they have a solid plane and, when unfolded, create an additional combustion chamber, and when folded, they fold inward along the bottom. The disadvantages of the Okhota furnace are the design complexity and high metal consumption.

A traveling composite stove is known (RF patent No. 164053, publ. 20.08.2016 under the heading IPC F24C1 / 16), which is a one-volume structure that combines a furnace and a chimney, in the form of a thin-walled pipe of variable diameter, composed of separate sections, where the furnace is directly lower sections filled with fuel. The disadvantages of the furnace are the need to use a cable to make the structure more stable and the need to use a fire retardant coating (when operating the furnace in a tent) to reduce the fire hazard due to the unregulated removal of combustion products through the holes in the bottom of the furnace part. A camping composite stove is used only for heating tents, huts and other light shelters. Cooking on it is impossible.

Known folding oven according to the Chinese patent No. CN209819589 publ. 12/20/2019 under the heading IPC F24C1 / 16. The folding furnace consists of a rectangular body formed by the bottom, two side, rear, front and top walls, hinged to each other. The upper wall is made with a hole into which a tubular chimney is inserted, consisting of several sections. The front wall of the furnace body is made in the form of a door with two rows of holes for air intake. The lower wall is equipped with folding supports. The disadvantage of the furnace is the relatively high complexity of assembly due to the large number of parts.

The technical problem of the claimed utility model is the elimination of these disadvantages, as well as the expansion of the arsenal of means of cooking in field conditions due to the proposed design of a camping stove, which allows it to be used simultaneously for heating and cooking.

The technical result is the expansion of the arsenal of means of cooking in field conditions.

The technical result is achieved due to the inventive design of a camping furnace, containing a housing with a combustion chamber placed in it, while the internal space of the housing is divided into upper and lower parts by a horizontal partition, a combustion chamber is installed inside the upper part of the housing with an offset to two adjacent side walls of the housing near them angular docking, in one of which a hole is made on the side of the combustion chamber, equipped with a damper, the inner space of the upper part of the housing is divided by vertical partitions installed evenly across the width of this part in the form of a labyrinth, forming adjacent spaces that communicate with each other, the side wall of the lower hollow part of the housing is made in the form of a door, on the upper surface of the body there are holes for installing a vertical chimney and a combustion chamber, while the vertical chimney is made in the form of a pipe of variable diameter, made up of separate sections with a variable diameter, connected by a telescope Thus, the section with the largest diameter of the base is installed on the upper surface of the furnace body, the combustion chamber is made with a perforated bottom and side walls, the combustion chamber is equipped with an insert made in the form of a plate installed perpendicular to the cross-sectional plane of the combustion chamber.

The camp stove can be equipped with supports. The supports can be attached to the lower part of the furnace body in any way, for example, hingedly for ease of folding and making the furnace compact when folded.

A viewing window can be made on the side wall of the upper part of the furnace body.

The camp stove can be equipped with carrying handles.

The combustion chamber and sections of the vertical chimney can be made in various cross-sectional shapes, such as round, oval or rectangular.

The lower part of the side walls and the bottom of the combustion chamber can be made in the form of a metal mesh. The metal mesh can be welded to the combustion chamber body.

To transport the furnace in the folded state, the sections of the vertical chimney and the combustion chamber are placed in the lower hollow part of the furnace body, and the supports are folded along the furnace body or removed. When folded, the stove is quite compact and can be transported in the trunk of any car.

The presence of vertical partitions in the upper hollow part of the furnace body provides a zigzag movement of the resulting smoke during combustion from the combustion chamber to the vertical chimney. Hot smoke in the course of its movement provides uniform heating of the upper surface of the furnace body, which is the cooking, and the lower hollow part of the furnace. The lower hollow part of the oven can be used as an oven. Thus, the proposed furnace design is multifunctional.

The presence of an opening in the side wall of the furnace body on the side of the combustion chamber installation provides a primary air inflow, and due to the division of the internal space of the combustion chamber by a vertical insert, a secondary air inflow is provided. The combination of primary and secondary air flows leads to stable combustion of the fuel. By means of a damper on the opening on the side of the combustion chamber, it is possible to regulate the flow of air into the combustion chamber in the required volume. The adjustment is carried out by means of a damper shift, which allows to control the draft, thereby adjusting the intensity of burning when cooking or controlling the duration of burning.

The high temperature and almost complete combustion of the fuel is achieved by the design of the combustion chamber with a divided space. The presence of an insert inside the combustion chamber provides a secondary air inflow, which contributes to the complete combustion of the resulting pyrolysis gases. In addition, the location of the insert inside the combustion chamber made it possible to avoid making an additional hole for the secondary air inflow on the upper or front walls of the furnace, which would lead to a violation of the integrity of the furnace structure. As a result, the camp stove has a relatively low smoke and sparking.

It is possible to manufacture the furnace in different sizes while maintaining the basic principles of its operation.

The utility model is illustrated by drawings, where in Fig. 1 shows a three-dimensional model of the furnace in folded form, in Fig. 2 shows a three-dimensional model of the furnace in assembled form, in Fig. 3 shows a combustion chamber.

The camping stove (Fig. 1) consists of a housing 1. The interior of the housing 1 is divided into upper 2 and lower 3 parts by a horizontal partition (not shown in the drawing). The side wall of the lower part 3 is a door that can be equipped with any overhead lock in the form of a bolt, wrap, hook and loop, etc. Inside the upper part 2 of the housing 1 with an offset to two adjacent side walls near their corner joint there is a combustion chamber 8 with a perforated bottom and side walls (Fig. 3). The height of the perforated side walls of the combustion chamber 8 does not exceed the height of the walls of the upper part 2 of the furnace body 1. The space formed by the perforated side walls of the combustion chamber 8 forms the furnace part of the furnace. The combustion chamber 8 is equipped with an insert 11, made in the form of a plate and installed perpendicular to the plane of the cross section of the combustion chamber (Fig. 3). The length of the insert 11 does not exceed the height of the furnace part of the combustion chamber 8. The perforated surface of the combustion chamber provides air flow, which contributes to the combustion process.

The bottom and side walls of the combustion chamber 8 can be made in the form of a metal mesh. In the side wall 4 of the housing 1, on the side of the combustion chamber 8, there is an opening 6 for air intake, equipped with a damper 7. The inner space of the upper part of the housing is divided by vertical partitions 5, installed evenly along the width of the housing, in the form of a labyrinth, forming interconnected adjacent spaces. This can be realized by connecting the vertical partitions 5 in series with opposite side walls of the upper part 2 of the furnace body 1. The number of vertical baffles 5 depends on the dimensions of the furnace, it is preferable to install two or more to create a zigzag movement of the resulting smoke.

On the side wall of the upper part 2 of the housing 1, a viewing window 12 is made to monitor the combustion process. Viewing window 12 can be made of any transparent heat-resistant material. On the upper surface of the body 1, holes 14 are made for installing a vertical chimney 10 and a combustion chamber 8 (Fig. 2). Holes 14 can be made with a rim for greater stability of the vertical chimney 10 and combustion chamber 8 installed in them, while the holes 14 are located in opposite corners of the upper surface of the furnace. The vertical chimney 10 is made in the form of a pipe of variable diameter, made up of separate sections with a variable diameter, connected telescopically, and the section with the largest diameter of the base is installed on the upper surface of the furnace body. The section diameters are selected in such a way that in the working position each subsequent section is put on with its wide part on the narrow part of the previous section. The combustion chamber 8 and sections of the vertical chimney 10 can be made of various cross-sectional shapes, such as round, oval or rectangular.

The sparks formed during combustion in the combustion chamber 8 come into contact with the walls of the upper part 2 of the furnace body, with partitions 5 located in it, while transferring heat to them, which contributes to spark extinction during the combustion process. Thus, most of the sparks enter the vertical chimney already cooled, due to which the vertical chimney heats up gradually.

The camp stove can be equipped with supports 13. The supports 13 can be attached to the bottom of the furnace body in any way, for example, pivotally for ease of folding and making the furnace compact when folded. Supports 13 can be made in the form of folding or removable legs of various profiles with prolegs. The camp stove can be equipped with carrying handles (not shown in the drawing) for ease of transportation.

The operation of the furnace is carried out as follows.

In field conditions, the stove is installed on a flat platform on supports. In the holes 14 on the upper surface of the body 1 of the furnace, a combustion chamber 8 and a vertical chimney 10, pre-assembled from sections, are installed. Fuel pellets are placed in the combustion chamber 8. Wood pellets are an environmentally friendly fuel with an ash content, as a rule, not more than 3%, when they are burned, more energy is released compared to, for example, firewood. Along with fuel pellets, cones, shavings, wood chips, charcoal can be used as fuel in the furnace. Ignition occurs through the hole 6 with the damper 7. The upper surface of the body 1 of the furnace is the cooking. During the operation of the oven, the hob and the lower 3rd hollow part of the oven, used as an oven, heat up simultaneously and over the entire area, which allows cooking food throughout the working space of the oven. Combustion is adjusted by supplying primary air through the damper 7. After the operation of the furnace, the vertical chimney 10 is dismantled, the combustion chamber 8 is folded inside one of the sections of the vertical chimney. The collapsible sections of the vertical chimney are removed into the lower hollow part 3 of the furnace. The supports 13 are folded along the bottom of the oven and the oven is ready for transport.

The stove can be used to heat tents and small dwellings, subject to fire safety regulations.

Thus, the inventive design of the camp stove is easy to assemble/dismantle due to the folding chimney and removable combustion chamber and can be used for heating and cooking. Due to the use of fuel pellets, which are environmentally friendly and inexpensive fuel, in the inventive camping stove, high heat transfer is achieved and the fire hazard during the operation of the stove is significantly reduced.
