Description

The alleged invention relates to devices for cooking hot food, boiled, fried and even smoked.

Mankind began to eat boiled food only with the invention of a ceramic cauldron, which was placed between stones on a fire. Then writing did not exist and priorities are determined by tens of thousands of years.

The Grand Duke of Kiev Svyatoslav of the Rurikovich family cooked independently on fire 1, planting a piece of raw meat 2 on the edge of a combat spear 3, together with the entire fighting squad, FIG. 1. This was noted in many annals of the beginning of the last millennium and, accordingly, N. Karamzin. in the first volume of his "History of the Russian State" M. 1816 v. 1.

With the development of blacksmithing in Russia, Tagan came into use, fig. 2, which is a hoop 4 commensurate with a cast-iron boiler or ceramic pot. Three legs 5 were attached to the hoop with rivets or blacksmith welding. During WWII, this was used in the occupation zone.

To prepare the stew, a set of products and water was laid in a boiler on a tagan 6, under which a bonfire 7 was built, Fig. 3. In winter, the tagan was placed in the furnace of a large Russian stove, and in the summer a bonfire was placed under the tagans in the yard. Sometimes fires occurred in wooden villages ...

Nekrasov said ... "will enter a burning hut" ...

This is a disadvantage of an open firebox.

During the Great Patriotic War in the Soviet Army there were service field kitchens, fig. 4. They consisted of a hemispherical boiler 8 with a cover 9 on the hinge, a furnace under the boiler 10 and a chimney 11. The whole device was mounted on a car trailer 12.

This analogue worked after laying a set of products in the boiler and kindling the required amount of firewood in the furnace. The flame of burning wood, heating the boiler, cooked food for the military in the field.

Burnt flue gases, having a lower specific gravity, were removed from the furnace through a chimney without causing harm to the cooks.

The lid was raised above the boiler only when necessary, but basically the lid hermetically closed the boiler.

The disadvantage of this analogue is the bulkiness and its redundancy for the needs of a small company of people, several people, and even more so for one person. This analogue can be transported only on the road and on a trailer to the car.

The prototype of the alleged invention is a household stove according to the patent of the Russian Federation 2618237 dated 05/05/2017, which improves Ishkov's household stove according to the patent RU 2070306 from 05/12/1991, FIG. 5.

The protopip consists of a hot water boiler with a stove 13 on the firebox 14 and pipes leading off the flue gases 15. Cookware is installed on the stove in the comforts. Fire chamber for solid fuel.

The prototype is based on the formation of hot gases during the combustion of fuel in the furnace. In this case, the bulk of the heat leads to heating the water in the boiler to heat the room in the cold season. Directly in the dishes in the comforts, the heat exchange from the hot gases in the furnace goes to the cooking of food according to well-known recipes and technologies.

The disadvantage of the prototype, with all its advantages, is its unsuitability for field conditions in an open field or in a forest, where a transportable device is required, but efficient in using heat from burning fuel.

The alleged invention is presented in Fig .: 6, 7, 8, 9, 10. It consists of a horizontal plate 16 with comforts and a vertical chimney 17, which is mounted to the segment cutout 18 at the narrow end of the horizontal plate 16 with two studs 19 on the lower the end of the chimney 17 and two proportional openings at the segment cutout on a horizontal plate, FIG. 8, 9, a grid-iron in the form of a flat lattice of steel wire and a furnace flat flap 21.

In the field, the stove is mounted on a recess in the ground 22, in which a firebox is created with a grate at the bottom of the recess for solid fuel: firewood, dung, dry grass or a driver blowtorch.

In the conditions of cultural gardening, the furnace can be made of a limited number of bricks.

Traditional cast iron of factory casting is preferable as the material for the plate, but sheet steel 3.0-3.5 mm thick is quite suitable. A chimney can be made of sheet steel with a thickness of 0.5-1.0 mm., See Uchyaev PN and other "Tin works" M. Engineering 1989. S. 210.

The segment cut in the narrow end of the horizontal slab commensurate with the diameter of the chimney is quite technologically advanced for modern production.

The grate is made of steel wire with a diameter of 4.0-5.0 mm in the form of a flat lattice with supporting U-shaped posts on the sides.

The device is equipped with a scoop and poker of known shapes, but commensurate with the firebox. The pipe is equipped with a commensurate dish-shaped lid to control the combustion mode of firewood in the furnace.

An experimental version of the alleged invention consists of half a typical cast-iron stove with one comfort for a pan with a diameter of 160 mm., Which is freely immersed in comfort until it stops on its side hinges. A chimney made of sheet steel 1.0 mm thick with a diameter of 140 mm with a length of 800 mm with two studs with thread Mb. The slab was mounted on silicate bricks in two rows, which formed a firebox. Dry branches were used as fuel, which is always enough in the garden. The grate was welded from F5 mm wire. Cooking time for soup or porridge was 15-20 minutes. Ash scoop spilled to the ground before germination, and then on a pile of manure.

Contemplation of a burning flame in a firebox creates comfort ...

The practical operation of the prototype of the alleged invention during the summer in the conditions of a suburban garden plot showed it to be a workable and useful device.
