Description

The present invention relates to articles of everyday life and is intended for boiling water and preparing hot food in camping conditions.

A known design of a traveling samovar according to the patent of the Russian Federation No. 2228703, intended for use in road conditions.

The prototype has the following disadvantages:

1. The presence of an open flame makes it unacceptable to use it in a tent or inside the car.

2. Fuel in the form of chips, brushwood and the like of combustible materials in winter or in rainy conditions must be carried with you.

3. The complexity of the design - the need for assembly, disassembly and washing after use.

4. The need to carry a flask for water with you. The aim of the proposed new design of the samovar is to eliminate all of the above disadvantages of the prototype.

This goal is achieved by the fact that the design of the samovar is made non-separable, as the fuel used is dry fuel such as tablets "Starter fire" company "Siberian Plain" (Novosibirsk).

Fuel is burned inside the flame tube, which makes it safe to use the samovar both inside the camping tent and in the car (with the window open) regardless of the time of year or weather conditions. Samovar can be used on the road as a flask for storing water.

The essence of the proposed design is illustrated by drawings:

- figure 1 is a longitudinal section of the device;

- figure 2 is a top view;

- figure 3 is a section along aa (figure 1);

- figure 4 is a variant of the samovar - marching pot.

The samovar consists of an oval tank 1 (Fig. 1) with an integral ceiling 2. Inside the tank, the flame tube 3 is welded asymmetrically to its vertical axis 3. The bottom of the pipe 3 extends beyond the bottom and is welded to the base plate 4. The pipe 3 is provided grate 5, groove 6 (blew), rotary valve 7 with handle 8 and threaded cover 9.

Inside the pipe is equipped with a C-shaped convective tube 10, the ends of which are welded into the wall of the flame tube and connect the cavity of the tube with the cavity of the tank 1.

A fitting 11 with a threaded plug 12 is welded on to the ceiling surface 2. A holder 13 with a threaded cover 14 and a rubber gasket 15 is welded to the right side of the ceiling. The cover is equipped with a threaded plug 16. A metal cup 17 with a supporting flange is inserted inside both 13. hinges 19 for the handle. In groove 6, a support 20 for a fuel tablet is mounted. The container body is wrapped with insulating material 21.

Work with a samovar in the following sequence.

Unscrew the lid 14, remove the glass 17, fill it with a product, such as stew, and place it back in the container. Screw the cap 14 and unscrew the plug 16. Unscrew the plug 12 and fill the tank with water. From the top of the pipe 3, screw the cap 9 and pour dry fuel tablets into it. Through the groove 6, a fuel tablet is placed on the stand 20 and a match is set on fire. The flame of the tablet through the grate 5 ignites the tablets on it.

The combustion products of the fuel exit through the top of the pipe 3, giving off heat to its walls during movement and heat the convective tube 10.

Water heated in the tube 10 in the form of a water-vapor emulsion leaves its upper end into the tank under the upper layer of water in it (the end of the tube is brought out under the ceiling at a distance of two to three pipe diameters). Cold water from the bottom of the tank enters the place of the left water at the lower end of the convection tube. (The process is similar to producing steam in an industrial steam boiler.) The movement of water in the tube intensifies convective heat transfer in the entire tank, which speeds up the process of heating and boiling.

The heat given off by the combustion products to the side walls of the flame tube 3 and its asymmetric arrangement in the tank also intensify the process of heating the water in the tank.

When boiling water (steam exit from holes 11 and 16), the combustion of fuel can be stopped by closing the blower by turning the valve 7 or wait for the complete combustion of the fuel.

Opening the lid 14, remove the glass 17 with a heated stew or other product. Boiling water is drained through the hole 11 to make tea, coffee, etc. Thermal insulation 21 of the samovar body reduces heat loss and increases the safety of handling the device.

Depending on the volume of the capacity of the samovar, 2-3 clips 13 with the corresponding number of glasses 17 can be welded into the ceiling.

Figure 4 shows a variant of the samovar - camping pot.

It is a simplified construction of a samovar and can be used in the field as a regular army bowler with a camp kitchen. However, a limited group, for example, a soldier cannot carry a camp kitchen with him and is forced to eat dry rations. The presence of a modernized pot allows you to cook hot looking without camp kitchen and without making a fire.

In a camping pot, you can quickly boil water and use dry "Rolton" mixes to make soup or warm the stew (you can put a can of stew in the pot without opening it). In the pot you can cook sausages, sausages, chicken eggs. You can make tea or coffee with boiling water.

The advantages of the proposed instructions of the samovar and pot over other products of a similar purpose are as follows:

1. Filled with water and fueled with fuel, it is always ready to work.

2. Full autonomy anywhere and in any weather.

3. A closed flame allows it to be used indoors, in a tent and in a passenger compartment.

4. Serve as a flask for storing water.

Camping samovar can be used by tourists, hunters, fishers and geologists in hiking conditions in any weather.

The construction will be useful for truckers and motorists, especially in conditions of traffic jams on the roads (traffic jam on the Don highway (Moscow-Rostov) in the winter of 2009-2010 was ~ 26 km long with 3-4 cars stopped days).

Claims (2)

1. Camping samovar, consisting of a container, a flame tube with a grate, a blow gate valve and a base plate, characterized in that the flame tube is installed asymmetrically inside its container with its vertical axis, and a C-shaped convection tube is welded inside the pipe, while its ends go into the cavity of the tank so that the lower end is located at the bottom of the tank, and the upper below the plane of the ceiling by an amount of the order of two to three diameters of the tube. 2. The samovar according to claim 1, characterized in that a holder with a threaded cap is welded on the ceiling of the container, and a hollow metal glass with a supporting flange at the upper end is inserted inside the holder.
