Description

FIELD OF TECHNOLOGY.

The invention relates to the tourism industry, namely, to life support in field conditions, in particular, high-altitude conditions for the rapid preparation of food and keeping it hot or warm.

STATE OF THE ART.

Cooking in the field must meet the following conditions: food must be cooked quickly, kept hot or warm for a long time, and cooking pots must not have a complex design.

The prior art widely presents devices that allow cooking food in the field fairly quickly, especially in high-altitude conditions. In particular, the dishes for cooking food in these conditions have a number of specific features - due to the low pressure, the food takes a long time to cook, and the harsh climatic conditions do not allow maintaining the required temperature of the cooked food, which ensures replenishment of energy.

Utility model patent RU 142640 (Military Academy of Logistics named after General of the Army A.V. Khrulyov) discloses a device for cooking in high-altitude conditions, consisting of an army pot, a lid, a handle and a wire loop handle. The lid has a socket in which a high-pressure outlet check valve is attached, a sealing gasket is also located along the edges of the lid, and there is a groove on the outside of the pot. The pot is filled with semi-finished food, closed with a lid and hung by the wire loop handle on the fire. Steam is formed in the vessel and the pressure increases. Under the influence of high pressure, higher temperatures are formed in the vessel (above 100 ° C) and the food is cooked much faster. As stated in the patent, equipping the personnel of the Russian Armed Forces, climbers and tourists with this device for cooking will solve a large number of problems associated with the quality of life in high-altitude conditions.

The disadvantages of the known device include the fact that the patent does not disclose how the sealing gasket is fastened, which does not allow one to judge the tightness of the pot. In addition, the fastening of the pot lid is provided only on one side: when the pressure increases, the lid may become skewed, which also leads to a violation of the tightness. In addition, the design of the pot does not provide any thermal insulation of the pot according to the thermos principle, therefore, the prepared food will cool down quickly.

The closest cooking pot for use in high-altitude conditions is disclosed in the patent for utility model CN 201640874 U (UNIV PLA 3RD MILITARY MEDICAL). The multifunctional cooking pot consists of a cooking pot body, an inner container and lids (inner and outer). The inner lid with an air injection valve is connected to the neck of the cooking pot body, and the inner lid and the cooking pot body are sealed by means of a sealing gasket. The outer lid with an internal thread has a threaded connection with the inner lid or with the lower end of the cooking pot body. The cooking pot is equipped with two hollow ventilation nozzles located on two side surfaces of the cooking pot body, and the bottom of the cooking pot has a threaded connection with the lower part of the cooking pot body. When heating the cooking pot in the open air, no open flame is required, and heating can be carried out in various ways, so that the dangers caused by fire in the open air are eliminated. For example, in one embodiment of the utility model (Fig. 3), the outer cover can be made with a passage in the form of an opening and screwed to the bottom of the boiler body, due to which the boiler can be heated by a heat source obtained, for example, by burning manure. In other embodiments of the utility model, the fuel can be placed directly on the bottom of the boiler, or on a screwed cover (without a passage).

As follows from the description of this patent, the kettle can be used in mountainous conditions, in particular, on plateaus (i.e. on plains lying relatively high above sea level and separated from neighboring terrain by steep slopes) without the use of open flame and eliminating the risk of fire in extreme field conditions, and also allows heating food under conditions of reduced pressure in a short time.

The disadvantages of the closest technical solution include the fact that such a kettle cannot provide a long-term intensive supply of heat for cooking hot food or keeping it hot, but can only be used to heat it. The presence of ventilation nozzles, according to the authors of the patent, promotes the flow of air into the space between the body and the inner container, however, such air supply will not be able to support combustion due to the occurrence of draft, but can only remove gases generated during combustion, and also promotes rapid cooling of the heated product. In addition, the patent emphasizes that the authors of the patent try to avoid the occurrence of an open flame, and, therefore, such an important component as heating by radiation is excluded from the heating process of the kettle. Such heating components as heating by convection due to the release of combustion products or heating due to the thermal conductivity of the material from which the kettle is made, although present, but due to the design of the known kettle, focused on the use of the above-mentioned specific fuel, do not make a significant contribution to heating.

In our opinion, the closest technical solution does not allow it to be used not only for cooking in the field, but even for keeping food warm.

All of the above may create certain technical problems that require solutions.

IMPLEMENTATION OF THE INVENTION.

The proposed pot was created as a universal device for cooking, performing two functions - the function of a pressure cooker, which, in particular, allows you to quickly cook food in high-altitude conditions, as well as on flat lands, and the function of a thermos, which allows you to keep cooked food for some time at a comfortable temperature.

The kettle in accordance with the invention includes (see Fig. 1) an outer part - a jacket (1), an inner part - a flask (2). Folding handles (3) and legs (4) are attached to the jacket. A lid (5) is installed on top of the kettle.

The jacket (1) and the flask (2) (see Figs. 2 and 3) are made of stainless steel and have the shape of a cylinder with a rounded bottom, while the flask is installed in the jacket with the formation of an air gap between them. A flange (6) is made in the upper part of the jacket, and a flange (7) is made in the upper part of the flask, which is in line with the flange of the jacket. The flange (7) is made with a shoulder (8), which ensures the alignment of the flanges (6, 7), as well as a tight fit of the jacket to the flask in the area of the shoulder (8). It is also possible to make a flange (6) with a shoulder, and a flange (7) without a shoulder, in which case a tight fit will also be achieved, ensuring the sealing of both the flask and the boiler itself.

In the upper part of the jacket (1) below the area of contact of the jacket (1) with the collar (8) there are slots (9) for the outlet of gaseous combustion products, and in the bottom of the jacket there is an opening (10) for mounting the pot on a gas or petrol burner (not shown). The jacket is provided with a damper (11) (see Fig. 4) made in the form of a ring with slots (12) arranged in such a way as to partially or completely cover the slots (9) of the jacket (1) and installed on the inside of the jacket (1). It is also possible to install the damper on the outside of the jacket. The slots (9) in the jacket are covered by turning the damper (11) using a lever (13).

In the lower part of the jacket (1) under the rounded bottom of the flask (2) above the opening (10), there is a flame spreader (14) (see Fig. 5 and 6), improving combustion and heat transfer due to the occurrence of draft in the air gap between the walls of the jacket and the flask. The flame spreader (14) can be made in the form of a conical ring with a profiled wall (15) in the form of successively located protrusions and depressions. Such a design of the flame spreader (14) allows for uniform distribution of the flame and gaseous flows in the gap, directing them along the walls of the flask and facilitates rapid heating and cooking of food.

The lid (5) (Fig. 7) is made with a silicone sealing ring (not shown) installed in the groove (16) and hermetically closes the pot, simultaneously uniting the flask and the jacket. The sealing ring increases the pressure in the flask to 3 atmospheres, which makes it possible to reduce the cooking time in the pressure cooker mode, and at high altitudes makes it possible to bring the contents to a boil - at an altitude of 3000 meters above sea level, the boiling temperature is 90 ° C, and at an altitude of 6000 meters above sea level, the boiling temperature is 80 ° C. The walls of the lid (5) of the pot can be made double. In this case, an air gap is formed between the double walls, which contributes to additional thermal insulation of the flask when cooking, as well as the entire pot when using it in the thermos mode. The lid is held on the pot with clamps (not shown) according to the quick-release principle. A thermometer (not shown) and at least two valves (not shown), one of which is an emergency valve, can be installed on the lid to ensure trouble-free operation of the boiler.

Example of implementation of the invention.

The flask (1) is inserted from above into the jacket (2) (see Fig. 2), a valve (11) with a lever for moving it is mounted on the inside of the jacket and the kettle is closed from above with a lid (5), made with double walls and a groove (16), in which there is a sealing ring made of food-grade silicone.

A flame diffuser (14) is installed in the form of a conical ring with a profiled wall, and the diffuser is installed so that the smaller conical base of the ring is located closer to the opening (10), which ensures the direction of the flame along the walls of the flask.

The lid is secured with three clamps that simultaneously connect the flask, the jacket and the lid. A thermometer and two valves are installed on the lid, one of which is an emergency valve.

The handles (3) are mounted on the shirt and the legs (4) are installed. A burner is installed under the hole (10) in the bottom of the shirt (1) and water is poured into the flask (2) and the products intended for cooking are placed.

Next, the lid (5) is secured with clamps and the burner is lit. The burner flame in the lower part of the flask passes through the flame spreader (14), rushes upward between the walls of the flask and the jacket, which facilitates rapid cooking of food and exits through the upper slots (9) in the jacket (chimney).

After cooking, the hole (10) under the burner in the jacket is closed with a plug (not shown), and in the upper part of the jacket, a damper (11) is used to block the outlet of hot gases, which reduces heat loss and the pot can function as a thermos, keeping food warm without additional heating.

The above example of the invention should be considered as illustrating the invention, but not limiting it in any way. In particular, as indicated above, the claimed pot can be used not only in mountain conditions, but also in normal conditions, and it can perform the functions of a pressure cooker in field conditions. Therefore, other examples of the present invention are possible, which do not go beyond the essential features given in the formula.
