This invention relates to a mobile device equipped with a surface for cooking indoors and/or outdoors by direct contact.

In particular, this invention relates to a newly created mobile device, made with a continuous contact surface for food preparation, which can mainly be used indoors or outdoors and which allows both in the home and in professional terms to extend the cooking process, which until recently was carried out exclusively by means of stationary devices for professional cooking.

In recent years, consumers are increasingly using the cooking appliances carried out through direct contact with a heat source, which can be heated by coal, gas or electricity.

Typically, the surface intended for cooking, formed rectangular or round metal bars of welded rods or a single metal plate, made with through-holes or openings, in which place prepared the food.

These types of grids have the following disadvantages.

It should be noted that the products : what I cooked on grills made from twigs or rods lose their nutrients, because the working temperature and low contact surface between the food and the bars do not contribute to the formation of thin film of scum that preserves the nutrients within the food.

Another disadvantage of conventional gratings is that they do not allow diet and balanced thermal processing of food, because they are not provided by the device to drain excess fat and fluids emanating from the food during its preparation.

In particular, the part of the said fat and liquids dripping from the food, is deposited on the heat source causes uncontrolled flames, which not only pose a danger to humans, but also change the taste and aroma of cooking food.

The rest of these secretions remains on the surface of food, causing it first boiling, then its burnt and, finally, its charring with a corresponding development of harmful substances and unpleasant taste.

Another disadvantage caused by the lack of plum and devices for trapping fat, is that their absence makes periodic cleaning and maintenance of grills for cooking difficult, glutelin the m and tedious process.

In fact, cleaning of grates requires very tedious and strenuous manual work, often using a metal brush to remove excess oil and fat, which cover touch the mesh structure of the lattices. If the residues are not removed, they can give unwanted and unpleasant taste of the food prepared during the subsequent heat treatment processes.

In addition, you should consider the fact that a grid of welded metal rods susceptible to rust and corrosion and have a relatively short service life.

As a result, the user is forced to replace the old grille, looking for a new grill on the market for the sale of spare parts, which offers spare parts of different sizes and different shapes.

In addition, cleaning is complicated by the fact that for more uniform distribution of heat between a heat source and a surface for food preparation can be placed accessories, distributing heat, such as stones or plates made of heat-conducting material, but also gets most of the allocations resulting from the cooking of food. If not periodically cleaned or replacement of these devices, distributing heat, all unwanted odors and fumes from the foregoing preparation processes t see you a again will appear in food during subsequent cooking processes. In addition, regular lattices have the drawback consisting in the fact that many foods, such as fish and fresh vegetables, easily crumble during their preparation and through the mesh of the lattice drop in the heat source.

The lack of surfaces for cooking, made from a single piece of metal and having apertures or elongated slots, is that they necessarily have a reduced thickness in order to facilitate the workflow, and therefore, they are susceptible to deformation caused by temperature changes.

After a short usage lattice of the specified type will not be able to keep prigotovlyaemye food, and, in addition, they will have the problems described above.

In the art of well-known surface used for cooking by contact in professional kitchens, fast food restaurants and chain restaurants full day.

Typically, these devices consist of a rectangular metal plate, which may have different sizes and to warm up from the bottom by electricity or fuel and which releases heat from the top, is made as a surface for cooking.

As a rule, the width of these plates is from about 30 cm to 90 cm, length about 40 cm to 80 cm, and their bearing to the construction is rugged enough to install it on your stove for cooking together with heating elements and all devices for temperature control, which is executed in the body of the plate.

These devices have the following disadvantages.

Periodic inspection, repair and maintenance of the devices of the specified type is complicated by the fact that access to the scanned item usually requires the presence of several operators to move the entire plate or disassembly of the device or the entire device.

Known lattice rectangular cooking have a drawback, which is that they are difficult to clean angular zones and do not have a homogeneous distribution of heat across the surface for cooking, because the contact point of the heating elements is transferred to a larger amount of heat than in other areas of the plate.

In fact, in these plates for cooking the temperature difference between the area close to heating sources, and areas of interest that are far from them, is 50°C.-70°C. as a result, if the user directs heat to cold surfaces, it overheats hot surfaces and Vice versa.

Finally, stoves for cooking, known in the prior art, not the substations are designed for use either indoors or outdoors.

In particular, this restriction is more concerned with all those restaurants that offer private Banquet rooms, located close to the kitchens, and they can easily get the waiters, as well as space in the open air, namely, roof gardens, terraces or outdoor swimming pools, which are far from the kitchens. In the last mentioned case, the waiters need to move quickly between the kitchen and tables set in the open air, in order to minimize the cooling of the food served.

Thus, the main purpose of this invention is to eliminate the above disadvantages by creating a mobile device, is made with an open contact surface for cooking indoors and/or outdoors.

Another important aim of this invention is to provide a device of the type indicated above, which can be easily used at home non-professional users for the implementation of the cooking process, carried out so far exclusively in professional kitchens, and which allows you to perform an inspection, maintenance and repair easier and more efficient manner in comparison with the known industrial stoves for the sentence is the service of food.

An additional objective of this invention is to provide devices for cooking together with the plate, which ensures uniform distribution of heat across its surface for cooking and allows the user if necessary to divide this surface into different temperature zones.

The next objective of this invention is to provide a device with a surface for cooking, which minimizes the formation of surface coating and facilitates cleanup.

These and other objectives and in accordance with the invention are achieved by creating a mobile device with an open contact surface for food preparation having the following characteristic features.

Objectives and features of the device made in accordance with the invention, will become apparent from the following description with reference to the accompanying schematic drawings, in which:

The description and drawings are considering is a non-limiting example of the device, which is generally designated by the number 20 position. Parts of the device 20 shown in the drawings, indicated by the number of items that are the same for similar or identical elements.

The device 20 made in accordance with the invention essentially contains the node 21 for cooking mounted on the support carriage 22, is arranged to move on the wheels 23.

The node 21 essentially has the shape of a truncated cone and includes a surface 26 for cooking essentially round shape, at least one internal combustion chamber 25 and the outer body 24.

Trolley 22 is made preferably from stainless steel and is formed essentially of the upper annular element 27 and the lower plate 28 having the form of a disk, the element 27 and the plate 28 rigidly connected together by means of vertical struts 29.

The element 27 is attached round the handle 35 to move the trolley 22 manually.

Knob 35 is designed for hanging such kitchen utensils, as ladle, spatula or fork, usually used for cooking, as well as to maintain the tray 60 is in the form of petals (Fig).

The trays 60 are made of a composite material (for example, material marked with the trademark CORIANŽ category El du Pont de Nemours and Company) or of C is tempered quartz, moreover, the shape of the trays provides the installation so that their inner curved edge 61 is located between the protruding rim 56 of the upper element 27 trolley 22 and the top surface of the round handle 35.

In this embodiment, the device for cooking the bottom plate 28 is connected with four wheels 23 mounted on the edges of the cross, but in another embodiment they can be connected with three wheels truck or similar supporting devices.

Round surface 26 is preferably made of metal (e.g. steel) with a thickness sufficient to ensure conservation of heat required for cooking.

In particular, it is preferable to use a polished steel plate with a thickness of from about 12 mm to 15 mm

A well-known method of deposition on the upper side surface 26 is coated with the layer of chromium, the average thickness of approximately 50 microns and a hardness of about 1000 units of hardness Vickers.

The upper side surface 26 is polished to reduce the surface roughness to 0.1 micron.

This type of mirror polishing improves Anticipada properties of the surface 26, facilitates the cleaning process specified surface and reduces the amount of infrared radiation based on the it space, surrounding the cooking device and directed to the user.

This essentially there is no overheating of the space surrounding the cooking device, and the person who has to do the cooking process.

Moreover, the layer of the chrome coating keeps the heat in the topmost surface layer 26 and provides a constant surface temperature, which corresponds to the temperature of heat treatment of food, and thus, consumes less energy than the amount needed for normal ovens.

In addition, it should be noted that the surface 26 is inclined from rear to front at an angle, whose value ranges from 1° to 2° relative to the horizontal plane, and has a notch 30 at the forefront, the need for which will be explained later.

As clearly seen from Fig.6, the surface 26 is connected, for example, by welding with the speakers on the periphery of the frame 36, which is formed by the inner strip 37, the rising inclined surface 26, and the outer strip 38, which is essentially horizontal.

On the back of the arch framing 36 specified outer band 38 has a through hole 39, the purpose of which is described below.

In an exemplary embodiment, the node 21, zobrazeno 7, 9 and 10, under the surface 26 is only one combustion chamber 25, which is preferably made of stainless steel sheet.

The chamber 25 is limited to the outer skin in the form of a truncated cone, which closed top surface 26 and the lower bottom wall 31 made through the vent holes 32.

Through holes 32 are of such size, shape and location, which supply to the burner 33 outdoor air in sufficient quantity for proper gas combustion.

The chamber 25 contains at least an ordinary gas burner 33 which is preferably made of chrome steel, has an essentially circular and tubular cross-section and very good provides more uniform heating of the surface 26.

A well-known manner burner 33 is attached properly to the bottom wall 31 of the chamber 25 and is connected with a set of 34 gas valves, which are outside the specified camera 25.

Kit 34 gas valve has two knobs on F and G, which are designed respectively for the ignition of the gas in said burner 33, for example, using a conventional piezoelectric ignition and to regulate the flow of gas to the burner 33 until then, until it reaches the set temperature.

The user can check the correctness of the work is oralce 33 through a viewing window S, made in the outer housing 24 in place that aligns with the hole in the outer casing of the camera 25.

The set 34 of the valve meets all the regulating devices used, as a rule, to regulate and monitor the correct operation of the devices of the specified type and which are well known to specialists in the art as not to require further description.

Suffice it to say that the handle G adjustment gas is not activated until then, until you light the fuse burner 33.

With the surface 26 can be connected to a thermal sensor of a known type, such as thermoelectric sensors 40 (Fig), for example, these sensors may be located in the cutouts made in the body surface 26, to measure the difference between the temperature of the surface 26 and a set temperature of heat treatment.

After ignition of the igniter kit 34 valve supplies gas to the gas burner 33 in that case, if the temperature of the surface 26 is lower than the temperature selected by the user.

If there is a need to increase the surface temperature for cooking, gas enters the burner 33, where it is ignited by the igniter.

Gas burner 33 continues to work as long as the temperature of the surface 26 below the temperature set by the user is elem, or until until the user turns the handle G in the off position.

It is obvious that the proposed device has an automatic fuses, which will be triggered in the event of a failure, e.g. due to a random failure of the gas supply to the burner 33.

A well-known method of a fuel gas, such as natural gas or propane, is supplied from a portable gas cylinder connected to the adjusting valve 34 through a flexible tube, not shown in the drawings.

The cylinder is located on the bottom plate 28 of the trolley 22 and fixed on the place known and undescribed means of attachment.

Under 21 posted by the reference shelf 43, attached to the posts 29 of the truck 22, for example by welding, to set her tank 44, the purpose of which is described below.

The upper annular element 27 and the lower element 28 in the form of a disc carts 22 are articulated two door 50 having a semicircular cross-section, can be moved between a closed position in which the door limit the cylindrical body of the truck 22 (figures 1, 2 and 3), and an open position in which they provide access to the internal shelves 28 and 43 of the truck 22 (figure 4, 5 and 6).

In the bottom shelf 28 having the form of a disk made through holes 41, intended for receiving the stream of light is its air to the burner 33, even if the door 50 is in the closed position.

In an alternative embodiment, or in combination with the specified ventilation holes on the outer edge of the shelf 28 of the trolley 22 can be made of the recess 42, as shown in figure 4 and 5.

In an exemplary embodiment, the node 21, shown in Fig, 11 and 12, under the surface 26 are located near two of the combustion chamber 25. The top of the combustion chamber are closed surface 26 and bottom wall 31, is made with ventilation apertures 32.

In each of the chambers 25 a corresponding gas burner 33, made of chromed steel, with circular cross-section and passing with the formation of one or more semicircular branches, which, in particular, the need for more uniform heat distribution within the semi-circular surface 26.

While the proposed device allows heating only half of the surface 26 in the case when you need to cook small amounts of food, or heating surface 26 at the two sites, which have different surface temperatures, one temperature is designed for cooking, and the second temperature for pre-heating prepared food or to heat the already cooked food.

Hot convection air is Apuseni burners 33 within the combustion chamber (figure 10) or within the two chambers 25, located near (Fig), goes along the back side surface 26, and exits the previously described holes 39, made in the outer edge 36.

You should pay attention to the fact that design one or two cameras 25 burning, adjacent and having one or more burners 33, allows you to easily remove them from the truck 22 and surface 26 in case of failure or periodic inspection and maintenance.

In particular, a simple screw attachments not shown in the drawings, connect the bottom wall 31 of the cameras 25 burning with the corresponding threaded sockets 55 (Fig), which is formed on the back surface 26.

After simple removal of these threaded devices and disconnecting a gas-feeding tube from a group of valves 34 and the chamber 25 and all functional parts located therein, such as one or more groups of valves 34 and all connections to control devices that are commonly used to adjust and verify the correct operation of the device 20 of the specified type that can be easily removed from the device 20.

The back surface 26 in a location corresponding to the recess 30, is made on the leading edge of the attached collector tube 45. This tube 45 passes obliquely down through the hole in the bottom of the chamber 25 and has a discharge spout, of th is th directly over the vessel 44, above.

As is clearly seen in Fig, the tube 45 is used to capture and directions to the vessel 44 all those fluids that are released from the products And during their preparation and flow down along the inclined surface 26 until they reach the notches 30.

As can be seen in the enlarged view Fig, the edge of the recess 30 is tilted, contributing to run-off fluids to the tube 45, which directs them into the container 44. The latter can be periodically removed from the truck 22 for removal of waste collected inside it.

From the above it is evident that the main purpose of the present invention is achieved by the creation of the mobile device 20 for cooking indoors and/or outdoors where there are no disadvantages inherent in prior devices.

Moreover, the proposed device 20 can be easily used for cooking at home and cooking in industrial and professional environments.

In fact, in everyday life, the user can use the proposed device 20 instead of the usual lattices, whereas the professional user can almost be relieved of all limited opportunities inherent in known devices for cooking.

The proposed device 20 for cooking has a plate 26, which is intended for contact is prigotovleniya food which allows you to perform the cleaning, maintenance and repairs easier and more rational way, and to improve or at least to achieve the same quality of the cooking, as in professional kitchens.

Moreover, it is easy to inspect and service the device 20 due to the fact that the camera 25 and the associated valve device 24 is installed with the possibility of disconnection.

Additional outcomes of the device 20 are reducing the formation of surface residue and runoff collection and removal of all residue resulting from cooking.

Another result obtained from implementing the proposed device is that it can be used to cook food, which cannot be prepared by known lattices for cooking due to their limited size or violation of their integrity during cooking.

In addition, the proposed device 20 provides even heat distribution across the surface 26 and, if required by the user, distributes coming from the surface of heat through more combustion chambers, which can be heated selectively or separately.

Well it is clear that the device 20 can perform modifications and changes, SOS is awsomee the subject of this invention, without departing from the scope of the invention defined in the following claims with reference to the accompanying drawings, and therefore from the scope of protection of the industrial inventions.

The surface 26 may have, for example, oval or rectangular in shape or may contain one or more sections, made with shallow grooves or irregularities.

On the other hand, the cart 20 can have a different configuration and be made of materials which differ from those described above.

Instead of folding doors, 50, used in the described embodiment, the invention can be used in sliding doors or doors that are attached with the possibility of detaching the upright support frame 29, or alternatively, can be used only one hinged or sliding door.
