Description

The utility model refers to an autonomous device for boiling water, intended primarily for serving mass events.

When food service activities in nature is not always possible to connect to the electrical network, therefore, in some cases, the only way out is the use of autonomous equipment that runs on a more acceptable solid fuel under such conditions. For boiling water, traditional samovars are perhaps the most convenient to use under such conditions. But when several hundred participants of the event are to be served at the same time, the traditional capacity of the samovar (up to 50 liters) becomes clearly insufficient. Increasing the number of samovars involved requires an increase in support staff and does not provide the necessary level of service and security. Direct constructive increase in the capacity of samovars is prevented by the output of their weight characteristics beyond the limits of operational convenience, because according to the ancient formula, 1 liter of samovar volume approximately corresponds to 1 kg of its weight. In this sense, split designs of samovars become relevant.

Known is the marching samovar (patent of the Russian Federation No. 2228703, IPC: A47J27 / 21, published on May 20, 2004), consisting of a flame tube and a body, which is divided into large and small vessels, which are made in the shape of a crescent in their state, they compress the flame tube with their upper internal surfaces, holding it, and in the folded state they can accommodate a small vessel inside a large one. Suspensions with numerous openings are attached to the lower ends of the vessels in such a way that, in working condition, they are closed, forming a grate. To create the body of the samovar, by connecting the vessels together, they are equipped with quickly detachable latches. In addition, a large vessel is provided with two folding legs, and a small vessel is equipped with one, in order to allow the samovar to be installed in the working position with a certain gap in relation to the installation surface, ensuring air access to the fuel through the grate.

The well-known marching samovar provides the convenience of transporting it by one person in marching conditions with its small volume, but such a design is not suitable for use in servicing mass events, firstly, due to the unreliability of the quick release latches and folding legs with large volumes and a corresponding samovar weight secondly, due to the inconvenience of fuel loading through the upper cut of the flame tube, which, in working condition of the famous samovar, is rather high above the body. With a large capacity and the large dimensions of the samovar, including vertical ones, associated with it, this becomes extremely inconvenient. In addition, the well-known samovar is not equipped with dispensing cranes, which makes it unsuitable for servicing mass events, since it cannot ensure high performance of the samovar due to the inability to carry out the operational dosing of the finished product.

The closest in technical essence and results is the well-known samovar (certificate of the Russian Federation for utility model No. 17837, IPC: A47J27 / 21, published on 10 05.2001), which consists of a removable stand, detachably connected body (the traditional name of the samovar case) with a flame tube that is equipped with handles and a dispensing tap, as well as a detachably connected cap with a ring fitted with a hob and bumps-hooks (the traditional name for round thermally insulated handles for controlling the samovar cap).

Such a detachable design of a famous samovar allows you to detach the body with a lid when transferring the samovar to a heating source (household gas stove as described), and from it to the place of boiling water, which significantly reduces the weight to be moved. At the same time, the famous samovar does not have sufficient autonomy to use it when servicing public events, because apart from the samovar itself, a separate source of heating must also be delivered to the place of service, without which it cannot perform its main function - boiling water.

The basis of the technical solution proposed is the task of improving the performance of a samovar operating in autonomous conditions. Under the performance refers to the ratio of the number of finished products to the time spent on receiving them.

The declared problem is solved due to the fact that in the samovar, which has a body with a flame tube, which is equipped with handles and at least one dispensing valve, is detachably connected to the trunk cover, fitted with cones, hooks and a chimney with a burner, and also splitly connected to body removable stand, removable stand equipped with a furnace for solid fuel.

The supply of a removable stand with a furnace for solid fuel provides the samovar with the autonomy necessary for servicing public events, because it does not require additional separate sources of heating to perform its main function - boiling water. In addition, such equipment provides ease of use of the samovar for servicing public events, because with its large capacity and large dimensions associated with it, including and vertical, the traditional scheme of supplying the samovar with fuel becomes uncomfortable by filling the flame tube through the top. It is much more convenient to ensure the functioning of the samovar, controlling the furnace for solid fuel in its lower part.

The version of the body and the removable stand with thermal insulation also increases the usability of the samovar, because due to this, it heats up more quickly and keeps the working temperature longer, and burns the operating personnel are eliminated when touching its surface with open areas of the body.

Improving the usability of a samovar is also provided by the supply of its body with a water level indicator, because it is rather inconvenient to control the fullness of the samovar from above with its large vertical dimensions.

Also, the convenience of using a samovar is also served by the location of a water temperature gauge on its outer surface, which makes it easy to control this basic process parameter.

Supplying the samovar lid with a filler hole with a lid also improves its usability, because it allows you to pour or add water to the samovar without extinguishing the firebox and further removing the chimney and the samovar lid, which is especially important for large-capacity samovars.

Improving the ease of use of the samovar is the version of its implementation with several dispensing cranes, which are equipped with the body of the samovar, which allows to attract to its operation a number of personnel corresponding to the number of dispensing cranes, and this significantly speeds up the service of a large number of participants in mass events.

Also, the convenience of using a samovar is also served by a variant of its execution with supplying the lid with at least one additional hotplate for the teapot, and preferably several additional hotplates, which not only provides the necessary conditions for several people involved in its operation, but also allows for the preparation of on the traditional technology of various varieties of tea or herbal drinks to order.

Thus, each feature and set of features of a technical solution that is proposed solves the declared task of increasing the productivity of a samovar operating in autonomous conditions. Signs aimed at improving the ease of use of the samovar can reduce the time spent on its maintenance. Thus, with less time spent on the assembly and maintenance of the samovar get more finished products.

The essence of the proposed technical solution is illustrated in the drawing, where schematically, with conditional separation of parts in places of their detachable connection, the construction of the samovar is shown, which consists of a removable stand 1 detachably connected to the stand 1 body 2 with a flame tube 3 and a cover 4 detachably connected to the body 2 and equipped with cones-grabs 5 and at least one burner 6.

The body 2 is equipped with handles 7 and at least two dispensing cranes 8. Removable stand 1 is equipped with a circular handle 9 in the form of a hoop and a firebox for solid fuel. A solid fuel furnace consists of a door 10 with inspection openings, a combustion chamber 11, a grate 12, an ashpit 13, and a gate of the ashpit 14 that closes the ashpit from below.

In versions of the removable stand 1 and the body 2 is made of heat-insulated due to the supply of heat-insulating shirts 15 filled with mineral (basalt) insulating material.

Also in versions, the body 2 of the samovar is supplied with a water level indicator 16, and a water temperature indicator 17 is located on its outer surface.

Also in the versions, the lid 4 of the samovar is equipped with a vent 18 with a lid for steaming, which, if necessary, can be used to pour water. Spout 18 with a lid, also called a steam boiler, is a small round hole with a hinged lid.

In versions of the cover 4 of the samovar is equipped with at least one additional burner 19, designed to heat the teapots.

The body 2 of the samovar can be equipped with several dispensing cranes 8, and the number of handles 7 with which the body 2 of the samovar is supplied, for the convenience and safety of its movement, can be up to four depending on its weight. To increase thrust, the flame tube is connected to a chimney 20 with a burner.

The samovar is delivered to the place of use for servicing public events on a vehicle unassembled (with a separate placement in the vehicle of a removable stand 1, body 2 and cover 4) or assembled, ensuring its reliable fixation. At the place of unloading, the samovar is disassembled, unloaded and transported in parts to the place of operation, using the circular knob 9, knobs 7 and bumps-grip 5 when unloading and carrying it. Then the samovar is assembled by placing the removable stand 1 in the place of operation in this way so that it is convenient to maintain the solid fuel furnace, including operating the door 10. A removable stand 2 is installed on the removable stand 1 so that it is securely connected to the removable stand 1, and also the dispensing valves 8 are convenient but manage the attendants at their workplaces. The body 2 is filled with drinking water until the upper critical level is reached on the water level indicator 16, after having secured all the dispensing valves 8, it is covered with a cover 4, putting it over the central hole on the flame tube 3 until it mates with the trunk 2. Smoke is placed on the outer end of the flame tube 3 pipe 20 with a burner. After completion of the specified, the samovar is considered ready for operation.

The operation of the specified samovar is as follows. Check the closure of the ash pit 14, then open the door 10 and serves solid fuel (wood and / or charcoal) on the grate 12 filling the combustion chamber 11 to the required level. Solid fuel is ignited with an ignition fluid and after ignition is completed, the door 10 is closed, controlling the combustion process in the furnace through its inspection openings. Using the water temperature gauge 17, monitor the readiness of water for dispensing. After the temperature has been adjusted to the established technology, water can be primarily used to fill, through the dispensing taps 8, teapots with the possibility of using different types of tea and / or herbal drinks. After filling with boiling water, the teapots are installed on the burners 19, which the samovar's cover is provided with, for the brewing process in the best conditions. After this, water is dispensed with the required temperature for making tea, coffee, herbal drinks or broth and the like. Water distribution is carried out by constantly monitoring its level in the samovar using the water level indicator 16, and the temperature using the water temperature indicator 17. When the lower critical mark on the water level indicator 16 is reached, water distribution is stopped, water is added through the steam outlet to release steam 18, opening its lid, and again bring the water temperature to the technological parameters with the addition of solid fuel to the furnace or without it, if the intensity of combustion of the fuel is sufficient. When solid fuel burns in the furnace, the burning pyrolysis gases, which form at the same time, act both on the bottom of the body 2 and on its internal surface, passing through the flame tube 3. This double effect on the various surfaces of the body 2 that occurs in the samovar provides a much larger efficiency and speed of heating water than when heating water only from the flame tube. Solid fuel in the furnace is added as needed when it is burned, while the ash, which is formed, falls through the grate 12 to the ash pan 13 and is held in it by the ash gate of the ash pan 14.

Upon completion of operation of the samovar, remove the chimney 20 with a burner from it, remove the cover 4, drain the remaining water, remove the body 2, extinguish the furnace and free it from the remaining fuel. The components of the samovar load on the vehicle, pre-freeing the ash pan 13 from the ash using the gate of the ash pan 14.

The trial operation of the proposed samovar with a capacity of 300 liters in a heat-insulating version made it possible to establish the following parameters:

Time spent on the preparation of products, including filling with water, ignition, boiling:

- in the summer of about 60 minutes;

- in winter about 90 minutes;

- when boiling again 40 minutes.

The time spent on cooling (assembled) to a water temperature of + 50 ° C at an outdoor temperature of - 10 ° C for 20 hours.

Service speed (distribution of boiling water) up to 1200 servings per hour.

This service speed is unique to serving mass events. The samovar can be manufactured using well-known technologies and materials that are widely used at the present level of technological development.
