Description

The invention relates to multifunctional devices for home cooking, including meat, fish, vegetables and other food products, outdoors using firewood, coal or gas, and can be used as a device for barbecue, grill or campfire.

Known from the prior art devices for preparing food from metal (barbecue, grill) burn products if left longer than necessary, which will lead to the inability to eat them (RU 167432, IPC A47J 37/00, publ. 10.01.2017, RU 135241 , IPC A47J 37/00, published on December 10, 2013, RU 2504320, IPC A47J 37/00, published on 01.20.2014, RU 2453258, IPC A47J 37/00, published on 20.06.2012).

Known solutions for cooking from stone. For example, a stone grill for cooking steaks is known, consisting of a bamboo stand, volcanic stone and a protective tray made of stainless steel (Stone grill. Access mode: http://steaklovers.menu/food/1601. Date of access: 02.20.2019) .

In a known solution, the stone is heated for 30 minutes on the stove or placed for 40 minutes in the oven, then a steak is served to the visitor on a table stone grill. The disadvantage is the need to additionally heat the stone, in the case of prolonged cooking for a large number of people.

Known electric stone grill containing a granite slab (Electric stone grill. Access mode: http://olive-house.ru/servirovka/doski-servirovochnye/kamni-dlia-zharki/rotel-rotel-grill-1. Date of treatment : 02.20.2019).

In the well-known cooking solution, access to electricity is required, which makes it inconvenient to use the grill in the open air.

Known portable grill containing the main part with supporting means for the grill for cooking and a stone covering the Central cavity. When used, the stone lies directly on the surface of the burner or source of concentrated heat, separating the products cooked on the grill from above, from the fire below and providing quick heat distribution without penetration of the flame. Conversely, a stone traps drops of food and fat from above, turning them into a taste-provoking smoke for barbecue without ignition (US 5592871, IPC A21B 1/52, A48J 37/07, published on June 14, 1997).

In the well-known grill, stone is used in the form of silicon carbide material associated with porcelain. The disadvantages of the known solution is the need to use artificial components to create a heating surface.

The currently known stone devices are used mainly in the form of flat rectangular stone panels, without recesses in the form of a grill grate and without the possibility of changing the panel to clean ones for preparing several dishes of contrasting tastes. In addition, due to the high weight of such devices, it is very difficult to transfer them for cleaning in the dishwasher. The disadvantages of stone solutions are brittleness of the stone, heaviness, fracture from sudden changes in temperature, in contrast to metal devices.

It is known to use talcochlorite as a heat-intensive stone in heating devices, fireplaces, bath stoves, etc.

The closest in technical essence to the claimed invention is a thermo-moderating barbecue grill. A grill formed by a plurality of interwoven metal wires is adapted to be mounted above a heating chamber comprising a heating device formed in a barbecue for supporting a burning stone. A thermo moderating panel is installed between the grill and the heating device in order to reduce heat from the heating device. Thermal convection of air between the thermostatic panel and the baking stone can evenly heat the baking stone to form a uniform thermal distribution on it, to sequentially prepare the ingredients laid on the baking stone and protect it from cracks caused by uneven thermal distribution (US 20080295703, IPC A47J 37 / 04, A47J 37/07, published 04.12.2008).

The prototype claims a device for heating a stone and a panel of heat-insulating material, which protects the stove from excessive heat. The known device does not allow to cook food without oil, bake it evenly until cooked, and facilitate the cleaning of the grill.

The technical result consists in the possibility of cooking food without oil, baking it evenly until cooked, avoiding burning it regardless of cooking time, facilitating cleaning of the device, expanding the arsenal of technical tools for cooking food in the open air, and avoiding environmental damage when disposing of the device, due to the use of light interchangeable or built-in stone mini-panels on top of the stone base panels of natural stone or ceramic as the material of the device.

The essence of the technical solution lies in the fact that the stone panel for cooking on the grill or grill includes a stone panel base with a recess for at least one removable stone mini-panel. The base stone panel may contain round-shaped cutouts in the corners, providing the convenience of replacing interchangeable one or more stone mini-panels. Replaceable or built-in stone mini-panel can be made in the form of a flat plate or grill plate. The stone panel may further comprise a metal sheet mounted under the base stone panel. The stone panel may further comprise at least two profile metal pipes of square or rectangular cross-section, mounted under the metal sheet, on the grill or barbecue. The base stone panel and removable or built-in stone mini-panels can be made square or rectangular with straight or rounded corners or round. One or more walls of the stone mini-panel, made in the form of a flat plate, may contain recesses for collecting fat. The base stone panel and interchangeable stone mini-panels can be made of natural stone, preferably of talc chlorite, jadeite, talc magnesite, talc carbonate, granite, marble, and the like. or ceramics. The stone panel is used as a device, which is placed on top of the grill, grill or bonfire. The stone panel is used as a device, which is placed on a metal grill grate, if used on top of the grill.

In FIG. 1 shows a general view of a stone panel for cooking on a barbecue or grill in a preferred embodiment; in FIG. 2 shows top views of a base panel with recesses and cutouts with interchangeable mini-panels in the form of a flat plate and grill plate, isometric view of the base panel; in FIG. 3 is a top view and a perspective view of a rectangular base panel without cutouts with mini-panels in the form of a flat plate and a grill plate; in FIG. 4 is a plan view of a base panel with square mini-panels in the form of a grill plate and a flat plate (alternative embodiment); in FIG. 5 is a top view of a square-shaped base panel with a removable mini-panel in the form of a flat plate and a top view of a square-shaped base panel with a removable mini-panel in the form of a grill plate; in FIG. 6 is a top view of a round base panel with a mini panel made in the form of a grill plate; in FIG. 7 is a top view of a rectangular base panel with a mini panel made in the form of a flat plate; in FIG. 8 is a plan view of a rectangular base panel with three built-in mini-panels.

The claimed device is used as an additional device, which is placed on top of a barbecue, grill or bonfire, for cooking, by uniformly transferring heat from burning wood, coal or gas to a stone panel consisting of a base stone panel and removable or built-in stone mini-panels.

The implementation of the invention is illustrated by the following examples.

Example 1. In a preferred embodiment, the stone panel (Fig. 1, 2) contains a monolithic stone panel-base 1 of rectangular shape, with recesses 2 for a removable stone mini-panel in the form of a flat plate 3 and a removable stone mini-panel in the form of a grill plate 4. Replaceable stone mini-panels 3 and 4 are made of rectangular shape in different sizes. The stone panel-base 1 and interchangeable stone mini-panels 3, 4 can be made with straight or rounded corners. The recesses 2 are made with round-shaped cutouts 5 in at least two corners, providing the convenience of replacing interchangeable mini-panels 3 and 4. A replaceable stone mini-panel in the form of a flat plate 3 is provided around the perimeter (one or more walls) with recesses 6 for fat collection. The replaceable stone mini-panel in the form of a grill plate 4 has a relief 7 formed by local changes in the level of its surface, and this relief 7 has a pitch of 6-20 mm and a depth of 5-15 mm. Due to this, the effect of a grill grate is created. Under the base panel 1 is placed a metal sheet 8 (for example, black steel) to protect the material of the panels 1, 3 and 4 from sudden changes in temperature. The metal sheet 8 is placed on at least two profile metal pipes 9 of stainless steel square or rectangular cross-section. The device is heated by burning wood, coal or gas 10 at the bottom of the grill or barbecue 11, or from a fire. The device relies on a barbecue or grill 11 due to the weight of the base panel 1 and interchangeable mini-panels 3 and 4, which press the metal sheet 8 to the profile metal pipes 9. The base panel 1 and interchangeable mini-panels 3 and 4 are made of natural stone volcanic origin - talchochlorite.

Talkochlorite is a natural building and decorative material, a rock of metamorphic origin. It consists of talc (40-50%), magnesite (40-50%) and chlorite (5-8%). Technical properties: melting point 1630-1640 ° C, specific heat 0.98 kJ / kg ° C, thermal conductivity 6 W / m ° C, thermal expansion 0.001% / ° C

Example 2. The stone panel differs from example 1 in that the base panel 1 is made without cutouts (Fig. 3). Stone mini-panels 3 and 4 can be removable or integrated into the base panel 1.

Example 3. The stone panel differs from example 1 in that the replaceable stone mini-panels 3 and 4 are square in shape of the same size (Fig. 4). Moreover, as can be seen from FIG. 4, the plates can be arranged vice versa than described in example 1, that is, on the left there is a mini-panel in the form of a grill plate 4, and on the right a mini-panel in the form of a flat plate 3.

Example 4. The stone panel differs from example 1 in that the base panel 1 has a square shape in plan with a removable or integrated stone mini-panel. Either a mini-panel in the form of a flat plate 3 or a mini-panel in the form of a grill plate 4 can be used (Fig. 5).

Example 5. The stone panel differs from example 1 in that the base panel 1 has a circular shape with a removable or integrated stone mini-panel. It is preferable to use a mini-panel in the form of a grill plate 4 (Fig. 6). As in example 2, the base panel has no cutouts.

Example 6. The stone panel differs from example 1 in that it contains a base panel 1 of a rectangular shape with one mini-panel in the form of a flat plate 3 of a rectangular shape (Fig. 7). The recess 2 of the base panel 1 is also made with round cutouts 5 in at least two corners, providing the convenience of replacing the replaceable mini-panel 3.

Example 7. The stone panel differs from example 1 in that it contains a base panel 1 of a rectangular shape with three built-in mini-panels, two of which are made in the form of grill plates 4, and one in the form of a flat plate 3 (Fig. 8). In this case, combinations of mini-panels can be any. The base panel 1 is made without cutouts.

Example 8. In an alternative design (not shown in FIG.), Heat-retaining natural materials such as jadeite, talc magnesite, talcocarbonate, granite, marble, which retain heat for a long time, can be used for the manufacture of the base panel and interchangeable or built-in mini-panels, but have increased radiation background and lower thermal conductivity. Also, ceramics having properties similar to those of natural materials can be used as a material.

Example 9. A stone panel (not shown in FIG.) Is placed on a metal grill, if used on top of the grill. In this case, the use of shaped metal pipes described in example 1 is not necessary.

Thus, to achieve the claimed technical result when using the device, it is enough that the stone panel for cooking consists of a base panel, which is responsible for the accumulation of heat and a removable or built-in stone mini-panel for transferring heat to food. The principle form of interchangeable mini-panels is not. Due to the variety of possible options for the implementation of base panels and interchangeable or built-in mini-panels, the proposed device significantly expands the arsenal of technical tools for cooking outdoors. The elements of the stone panel can be round, oval, rectangular, square, etc.

A method of manufacturing a stone panel is as follows. On CNC machine tools for processing stone, recesses are cut out in stone slabs of various thicknesses and interchangeable panels cut from stone slabs are inserted into the stone base panel. Or holes are cut out in the base panel, similar to those cut out in interchangeable panels, to give the base panel the shape of a panel with integrated plates. The metal substrate is cut using a CNC laser cutting machine.

To prepare food on the claimed device, the stone panel-base 1 is heated, the food is placed on the surface of stone removable mini-panels 3 and 4, once turned over and served on the table. For example, meat products are cooked without the use of oil, without leading to the burning of the lower layer of products. Regardless of the cooking time, an edible crispy crust forms on a natural stone stone slab at the bottom of the food. It is not necessary to cook dishes on charcoal; it is permissible to start a fire under the stove, which will not affect the quality of the roast due to the uniform distribution of heat over the stove.

Compared with the known solution, the claimed invention allows cooking without oil, baking it evenly until cooked, avoiding burning it regardless of the cooking time, facilitating cleaning of the device, expanding the arsenal of technical means for cooking outdoors, moreover, the device does not harm for ecology in its disposal.
