Description

The utility model relates to devices for generating, storing and directing thermal energy for heat treatment of food products by burning various types of wood fuel. The generator is intended for use at home and at public catering establishments for preparing first and second courses.

Known device for heat treatment of food (see patent for utility model RU12649, IPC A47J 37/00, 23.07.1999), containing a housing with ventilation holes, holes for attaching removable supports and an internal frame installed in the housing on stops. The known device solves the problem of eliminating the risk of burns, due to the double walls of the case, but the design of the thermal field generator turned out to be cumbersome. The disadvantage of the known generator of thermal fields is that it is intended for a single mode of operation, which consists in frying food on a wire rack.

The closest analogue to the claimed utility model, which is adopted in this application as a prototype, is a known device for heat treatment of food products (see inventor's certificate SU 1651847, IPC A47J 37/00, 12/27/1988), containing a frame with removable folding supports shelf, grate, cover, removable fuel pan, on which a removable box can be installed. The removable sump for fuel is attached to the frame by means of a suspension and contains ventilation holes necessary for the flow of air into the combustion zone, as well as an opening for loading fuel. In the known device, in contrast to the known generator of thermal fields according to the patent RU12649, due to the presence of a box and a lid, the functionality is expanded, which makes it possible to cook food in several modes.

Common disadvantages of the known devices are:

- the impossibility of adjusting the intensity of combustion of wood fuel;

- impossibility to ensure continuous operation of devices when adding fuel and collecting residual combustion products (ash);

- uneven distribution of the heat flow over the volume of the processed food product;

- the lack of technical ability to change the area of the heat flow directed directly to food products;

- the lack of the ability to move and fix devices holding food products in the vertical direction above the heat flow source;

- impossibility of accumulating thermal energy and creating modes of minimum maintenance of the fuel combustion (smoldering) process;

- the impossibility of using devices in a closed space mode, with the complete placement of the product in the heat affected zone;

- there is no possibility to carry out separate cleaning of structural elements of devices and washing in dishwashers for household use;

The technical result of the utility model is to expand the functionality of the known devices by creating a quickly deployable multifunctional generator of thermal fields for heat treatment of food products, operating in variable thermal modes and using a wide range of kitchen tools, ensuring the minimum overall ratios of the generator in a collapsible form during storage and transportation with the ability to install the generator in various positions (lying, sideways, upright) , as well as the elimination of the disadvantages of known technical solutions.

The claimed technical result is provided by the creation of a multifunctional heat field generator, consisting of a body, a set of heat shields, including longitudinal heat shields, upper end heat shields and lower end heat shields, adjusting rods installed on the longitudinal heat shields, grate, valve rods, each longitudinal the heat shield is mated with the body along the corresponding upper edge of the body and has one degree of freedom, determined by the angle of rotation of the screen relative to the corresponding upper edge of the body and can be fixed in a given position using adjusting rods, while in the lower part of the body under the grate there are two pull-out trays , and holes are also formed that provide air supply to the combustion zone, and the size of the holes is adjusted by means of the valve rods, the body and longitudinal heat shields are made in the form of an arcuate shape, the upper end heat shields are They are made in the form of a frame with a set of plates fixed on it, and the rods of the longitudinal heat shields are made in the form of a rod, which is a set of chain links welded together. Such a design of the generator will make it possible to create a universal device for the thermal processing of food products.

The version of the multifunctional thermal field generator, containing a support structure, will allow the generator to be held in a predetermined position during cooking, transportation or storage.

An embodiment of a multifunctional heat field generator, in which the grate, longitudinal heat shields, upper end heat shields, lower end heat shields, valve-rod levers, ash pan handles are removable elements. With such a technical solution, the design of the generator, due to the absence of rigid connections between the elements, is less susceptible to thermal deformation, has the ability to easily replace the component elements, and allows the elements to be cleaned in a disassembled state, including, for example, in a dishwasher.

The essence of the proposed generator of thermal fields is illustrated by the following drawings and descriptions.

FIG. 1 shows a multifunctional thermal field generator containing a housing (1), a grate (2), longitudinal heat shields (3), upper end heat shields (4) and lower end heat shields (5), rods (6) longitudinally of heat shields ( 3), valve-rods (7), regulating the air flow through the holes (8), movement limiters (9) valve-rods (7), levers (10) valve-rods (7), retractable trays for collecting ash (11) with handles (12) mounted on them by means of a threaded connection.

Each longitudinal heat shield (3) is mated with the body (1) along the corresponding edge (13) of the body (1) with the possibility of rotation and can be fixed in a given position due to the lock connection (14) formed by the fastening element (15) mounted on the upper the end heat shield (4) and the fastening element (16) of the longitudinal heat shield bar (6). Each rod (6) of the longitudinal heat shields (3) is a rigid structure, contains several fasteners (16) for fixing the longitudinal shields (3) in different positions and can be welded from chain links.

The multifunctional thermal field generator contains a partition (17) located between the retractable ash collection trays (11).

The boom valves (7) regulate the volume of air entering through the holes (8) in the body (1). The limiter (9) determines the extreme positions of the valve-rods (7), in which the holes (8) are completely open or closed. The ash collection pan (11) allows the timely removal of waste products of combustion, in particular ash, from the generator of thermal fields without interrupting the cooking process.

The upper end heat shields (4) are made in the form of rigid welded frames, on which removable plates are placed, while the set of the thermal field generator may include additional plates that differ in shape and size. Thus, it becomes possible to place the object of thermal influence along the body at different heights, in accordance with the required cooking mode, for example, in the “oven mode” food is placed inside the generator, while providing a uniform thermal effect throughout the volume of food.

The multifunctional thermal field generator is divided into three functional areas. FIG. 2 shows the heat flow zone (18), combustion zone (19), ash chamber zone (20).

The heat flow zone (18) is limited by two longitudinal heat shields (3) and two upper end heat shields (4). The volume of the heat flux zone (18) can vary due to the fact that the longitudinal heat shields (3) are mounted on the body (1), using a cylindrical hinge, with the possibility of rotation around the edge (13) of the body (1) at the same time due to lock connections (14) can be fixed in a certain position. Depending on the position of the longitudinal heat shields (3), the required operating mode of the multifunctional thermal field generator is provided. A distinctive feature of the heat flow zone (19) is that its size, volume, and shape can change depending on the operating mode of the generator, while thermal fields of different properties are formed.

The combustion zone (19) is limited by the grate (2), the upper part of the body (1), two lower end heat shields (5). In the combustion zone (19), as a result of combustion of the placed wood fuel, thermal fields are generated.

The zone of the ash chamber (20) is limited by a grate (2), the bottom of the body (1) and two lower end heat shields (5). In the area of the ash chamber (20) there are two retractable trays for collecting ash (11), four boom valves (7), which provide adjustment of the supply air supply through the holes (8) in the housing (1) of the multifunctional heat field generator, as well as a partition ( 17), which is a stop for pallets (11).

Multifunctional generator of thermal fields works as follows.

In the initial position (see Fig. 3), the thermal field generator is disassembled in the mode of transportation and storage. The constituent elements of the heat field generator: one of the longitudinally heat shields (3), the upper end heat shields (4), the levers of the valve of the rods (10), handles (12), pallets (11) are placed inside the body (1) and are covered from above by the second longitudinally a heat shield (3), which serves as a “cover” during transportation and storage. In this case, the rods (6) are folded inside the body (1) due to the movable connection with the longitudinal heat shields (3). The remaining free space, for example on the scoop under the grate, is used for storage, cooking utensils, skewers, scrapers, knives, forks and other items. The space between the folded heat shields (3), the grate (2) can be used to store legs, a fireproof cover, kitchen utensils.

FIG. No. 4 shows a multifunctional generator of thermal fields in the “Fire bowl” operating mode. Longitudinal heat shields (3) are widely deployed relative to the edges (13) of the body (1) at the opening angle required for such an operating mode, and are fixed by means of rods (6) in the tool joints (14). Depending on the volume of fuel placed on the grate (2), the opening angle of the longitudinal heat shields (3) can be changed. The pull-out tray (11) holds the primary ignition volume of fuel, for example wood. After igniting the ignition fuel, the pallet (11) with the help of the handles (12) is pushed into the housing (1) until it stops with the inner baffle (17), as a result of which the subsequent ignition of the main volume of the fuel placed on the grate (2) occurs. By means of the levers (10), the valve of the rods (7), the air supply to the fuel combustion zone is regulated through the holes (8). In order to force the ignition of wood fuel, the longitudinal heat shields (3) can be rotated relative to the edges (13) of the body (1) to a position with a minimum gap between them. As the solid combustion products accumulate, the trays (11) are removed and the combustion products are removed from the ash chamber. When operating a multifunctional generator with a minimum amount of fuel, it is possible to place combustible fuel on the grate above one of the retractable trays (11).

FIG. No. 5 shows a multifunctional generator of thermal fields in the "Brazier" operating mode. In contrast to the mode of operation shown in Fig. 4, in the mode of operation of the Mangal generator, the longitudinal heat shields (3) are reduced to a much smaller opening angle by turning relative to the upper edges (13) of the housing (1). In the “Mangala” mode, a controlled directional thermal field is formed, which makes it possible to evenly distribute the heat flux along the entire length of the product located above the heat flux zone (18). Skewers with strung food products can be placed on the upper edges of the longitudinal heat shields (3), while the required height of the skewers is set by changing the opening angle of the longitudinal heat shields (3), while the density of the heat flux escaping directly from the heat flow zone also changes (eighteen). The regulation of the intensity of fuel combustion is carried out by means of the levers of the valve of the rods (7).

FIG. No. 6 shows a multifunctional generator of thermal fields in the “Stove” operating mode. Longitudinal heat shields (3), by turning relative to the edges (13) of the body (1), are installed along the width of the grating (21) and are fixed in this position by rods (6) using lock joints (14). The grille (21) is installed on the longitudinal heat shields (3). For cooking, cook utensils, such as pots, pans or a kettle, are placed on the wire shelf (21). For a more reliable fixation on the generator, the grate (21) can be made with a recess, such a design of the grate (21) will also prevent slipping of various kitchen items installed on the grate.

FIG. No. 7 shows a multifunctional generator of thermal fields in the “Oven” operating mode. Longitudinal heat shields (3) are completely closed. The body (1), upper end heat shields (4), lower end heat shields (5) and longitudinal heat shields (3) form a closed space that combines three zones: a heat flow zone (18), a combustion zone (19) and ash chamber area (20). In the “Oven” operating mode, a skewer or skewer with skewered food is installed on the upper end heat shields (4), the longitudinal heat shields (3) are completely closed and the cooking process takes place in a closed space like in an oven. Also, in the “Oven” operating mode, an object of heat exposure, for example, earthenware with food, potatoes “in uniform” or another product wrapped in foil, is placed on the coals laid out on the grate (2) or directly on the grate itself (2) ...

FIG. eight a multifunctional thermal field generator is shown in the “Flow displacement” operating mode, in which the first longitudinal screen (3) is opened to the required angle, and the other longitudinal screen (3) is covered. Thus, in the “Shift flow” mode, the heat flow is displaced and directed towards the open heat shield (3), which allows cooking food over the open heat shield (3), while the resulting fat secretions from the heated food do not directly enter the fire. , and drip onto the open longitudinal heat shield (3), which excludes smoke and uncontrolled temperature rise due to the ignition of fat that has fallen on hot coals. In this case, the intensity of fuel combustion is regulated by the rods (7) only from the side of the covered longitudinal heat shield (3).

The results of testing the prototype confirm the solution to the problem of the utility model, namely, the creation of a universal multifunctional generator of thermal fields that provides various modes of operation, "flexibility" in the implementation of heat treatment of products, increased energy efficiency, high efficiency.
