Description

The invention relates to the field of satisfying a person’s vital needs, more specifically to equipment for processing and cooking food, and can be used for grilling meat and sausages in mobile retail outlets for portable trading only in the open air, outside closed rooms. In particular, the invention relates to the construction of a portable grill, which can be carried by one person, in the form of a delivery tray.

Currently, such grill systems are designed in such a way that a person enters the carrier frame, lifts it and carries it with the help of the shoulder and waist belts. In front of the transferring person is placed a grill container mounted on a supporting frame, often with a connected or integrated capacity for stocks, for example, for buns. Behind the back of the transferring person is a gas cylinder mounted on a supporting frame in the cylinder frame in a receiving device for a gas cylinder, which provides heat to the grill.

Being inside the frame prevents movement, the process of installing the device on the frame is complicated. The manufacture of the installation is significant and the frame is heavy. Installation, due to the design of the frame, makes movement in the crowd difficult.

Known portable device for frying food containing a frame having means for mounting in front on the user's body, a roasting pan with operating mode controls (grill), mounted on the frame with the ability to control the user, a remote mounted power source for the roasting pan, which can be placed behind the back of the user, and at least one container for semi-finished products and at least one container for food products, as well as a system for monitoring the state of the power source, wherein the power source is located on the frame and is made with means of quick-detachable connection with the frame, containers, and to ensure balancing of the device as a whole, a supporting telescopic stand is attached to the frame in front of the user with the possibility of removal and made with a wheel on the free end for emphasis on the base to reduce weight when carrying (RU 32673, A47J 37/08, publ. 09/27/2003).

The disadvantage of this device is the inconvenience of use, since in order to balance the whole system must rely both on the user's body and on a support stand with a wheel, which, among other things, must be correctly set relative to the grill and the position of the user's body. It is also difficult to move the user carrying the grill on himself, since the balance is ensured by the constant position of the rack, and when moving the rack is shifted both in the transverse direction and vertically and must go around the obstacles with a wheel.

Known portable grill containing a stove for cooking, on the reverse side of which there is a burner with ballasts - igniter, in parallel with a trigger valve with a button and an electromagnetic valve, the combined output of which is connected to the burner inlet through a gas flow control valve, and a thermocouple, gas cylinder , the output of which is connected to a gearbox (pressure regulator), a support element, on which a stove and a gas cylinder, a locking valve, a flexible hose are placed. A gas leakage protection valve, a vertical sensor, gas supply tubes are introduced into the portable grill device, the gearbox output through a gas leakage protection valve is connected to a flexible hose, the output of which through series-connected gas supply tubes and a shut-off valve are connected to the combined input of the start valve with a button and an electromagnetic the valve, the output contacts of the vertical sensor are included in the coil circuit of the electromagnetic valve, the supporting element is made in the form of a tubular L-shaped bracket, on one side of the cat Opposite each other, gas cylinder fasteners and portable grill fasteners are installed, and on the other side is a cooking stove (RU 113938, A47J 37/07, published 10.03.2012).

The disadvantage of this solution is the inconvenience of using it, due to the fact that the L-shaped bracket is made in the form of two spaced pipes, and the belts are used only for manual carrying, that is, from place to place. This design is convenient for ground use, but not when carrying.

The basis of the invention is the task of creating a portable grill, convenient for use by one person, with safety devices designed to operate in both extreme and "normal" situations. Also the technical problem solved by the invention is the creation of a portable grill (barbecue), providing high mobility, ease of use when carrying and the possibility of its use for portable trading.

At the same time, a technical result is achieved, which consists in increasing safety by introducing the function of automatically turning off the gas supply channel in the direction of the grill tank.

These signs are essential to achieve a technical result.

The invention is illustrated by a specific example of implementation, which, however, is not the only possible, but clearly demonstrates the possibility of achieving this set of essential features of a given technical result.

The portable grill is made with a grill tank in front of the carrying person and with a receiving device for a gas cylinder behind the carrying person. The grill container and the receiving device for the gas cylinder are mechanically connected to each other, and shoulder and waist belts are placed between the grill container and the gas cylinder. The grill container (barbecue) located in front of the person and the receptacle for the gas cylinder located behind the back are connected to each other by means of a supporting element located between the legs of the person carrying the installation, while the grill container, the frame for the gas cylinder and the supporting element can be equipped with connecting elements connecting them to the shoulder and waist belts on the person carrying the installation. The weight rests on the shoulders with a pelvic strap, shoulder straps serve only stability and reliability.

The supporting element 3 between the container for grill 2 and the receiving device for a gas cylinder 13 is placed between the legs of a person 25, transferring the installation.

In addition, there are safety elements on the grill container, the supporting element and / or the frame for the gas cylinder that move or move when touched, which leads to the gas supply to the burner being cut off after a configurable period of time.

These safety features are mainly made in the form of legs, which also serve as supports for the grill placed on the ground when it is not transported. When placing the grill on the ground (axial load) or with a lateral load on these safety elements also depicted as legs, laid for this purpose, for example, in the form of a switching joint, switching elements start to work, including a clock with a countdown, after which it stops gas supply through the valve. These elements prevent situations when someone forgets to turn off the gas supply when turning off the grill. They also serve as safety features in cases where the person carrying the installation stumbles and falls. One of these elements constantly remains in its place or in the suspension, in the joint, so that after a short period of time the clockwork starts working with a countdown for stopping the gas supply.

The switching elements may be mechanical contacts. Preference is given to their execution in the form of a light stream passing through all safety elements, interrupted due to lowering to the ground or displacement of the safety elements, which leads to the start of the clock mechanism, which stops the gas supply in case the light stream remains interrupted during the time counted by the hour mechanism.

The switching joint is made in the form of an electric and / or pneumatic switching element. The electric and / or pneumatic switching element 20 on the grill container 2, and / or on the supporting element 3, and / or on the receiving device for the gas cylinder 1 is installed in such a way as to be actuated by touching and / or applying a load. The operation of one of the switching elements can also be carried out through intermediate links, such as delay links, which also leads to blocking the gas supply.

The interlocking circuitry needs a power source integrated into the grill as a battery. The advantage is given to solar panels connected to the grill, from which the battery is charged. Thus, the electrical communication elements 20 are powered by an integrated battery charged by solar panels or through an external charging station.

In order to avoid a constant sufficiently significant energy consumption due to the constantly active valve spool and to do without any electrical elements, incl. without a battery, another design described above is proposed - with a pneumatically controlled valve in the gas supply line. In this case, pneumatic switching elements, for example balls in the saddle, act as commuting elements. Using a hand pump or a pneumatic accumulator, for example a CO ₂ cartridge, known as a component of devices for preparing soda water, a pressure is created under the action of which a gas valve opens. Lowering to the ground or displacing one of the elements connected to the safety switching elements, for example legs, leads to the removal of air from the valve, followed by pushing one of the balls from the seat, as a result of which the gas supply is interrupted. Actuation delay is provided using pneumatic delay links in a well-known manner, for example, using one or more throttle check valves.

The following is an example of the design of a portable grill.

In FIG. 1 is a side view of a person 25 carrying an apparatus. The receiving device for the gas cylinder 1 is connected to the capacity for the grill 2 using the supporting element 3, located between the legs of a person. In addition, the installation is equipped with shoulder 5 and waist 6 belts as wearing devices and supports placed between the grill container 2 and the receptacle for the gas cylinder 1. The legs 4 are connected to the grill container 2 and the receptacle for the gas cylinder 1 by means of joints . Lowering to the ground or displacement of the legs 4 leads to the operation of the switching elements, interrupting the flow of gas through the valve. Inside the carrier there are gas transmission and control lines.

In FIG. 2 shows a grill installation with a person carrying it in a projection from above. Suspensions 14 and 15 are fixed on the supporting element 3 and on the grill container 2. The shoulder strap 5 is attached to the suspensions 14 and 15.

A type of construction with pneumatic communication elements is shown in FIG. 3. At the end of the leg 4, a clutch 7 is installed, pressing on the elastic plate 8 by means of a compression spring 9. The resulting sealed space acts as a pneumatic accumulator. When lowering to the ground or shifting the legs 4, the sleeve 7 comes into motion and rises above the elastic plate 8, which leads to the release of pressurized gas from the sealed space. Pneumatic switching elements 20 can be installed at the ends of the legs 4, and lowering to the ground or shifting the legs 4 leads to the release of air from the pneumatic switching elements 20.

The energy required to open and close the gas supply can be accumulated in the form of pneumatic energy, and a pneumatic gas valve can be used as a valve regulating the gas supply. Or the supply of pneumatic energy is carried out using an air pump 16.

In the portable grill, on the sides of the grill burner, there are two drip stacks connected with the grill stove (canting tin strips) so that dripping fat does not drip onto the burner, which also serve to evenly distribute heat. Stacks of fat can be removed from the grill. Thus, they can be easily cleaned. Below the grill burner are two removable grease cups. The grill should not be used without these cups. The grill rack, greasy cups and greasy stacks are removable and dishwasher safe. The grill walls are partially double, in order to achieve thermal insulation and to avoid the risk of burning when touching the external parts. A removable tin cover (packaging of cylinders) covers the cylinder, which gives the grill a good appearance. This cover has a hole on top, through which you can reach the cylinder valve.

The umbrella protects the user from too much sun and keeps the dirt coming from the grill from above (from birds). Umbrellas that have wind protection are recommended, i.e. which open up if they are swept from below by the wind.

Shelves for buns and napkins are also connected to the bracket connecting the gas bottle to the grill. These shelves are placed in front of the user.

A type of construction with full pneumatic communication of the grill is shown schematically in FIG. 4. In this scheme, pneumatic communication elements are designated as F1, F2, F3 and F4 by the number of legs 4. Compressed air is pumped into the compressed air source 17 by means of a manual air pump 16. The advantage of this design is that there is no need for electric energy and associated costs. A source of compressed air 17 provides a supply of compressed air depicted in FIG. 3 and 5 pneumatic communication elements. The release of compressed air from the pneumatic communication elements leads to the discharge of the pneumatic accumulator 23 through the throttle check valve 24. As a result of this exhaust ventilation process, the pneumatic gas valve 22 blocks the fuel supply 21.

In FIG. 5 shows a design variant with pneumatic communication elements for shoulder straps 5 integrated in suspensions 14 and 15. When wearing a grill using shoulder straps 5, the coupling 7 presses on the elastic plate 8, as a result of which a sealed space is used as a pneumatic accumulator. When the load is suddenly removed from the shoulder strap 5, the action of the tension spring 26 causes the clutch to move away from the elastic plate 8, as a result of which gas under pressure is released from the sealed space, which leads to the locking of the pneumatic gas valve 22 due to this exhaust ventilation process.
