Description

The technical field to which the utility model relates.

The utility model relates to the field of everyday life and public catering, and can be used for the preparation of barbecue and large-sized products from meat, fish, game, poultry and vegetables.

State of the art

A device for frying food products is known (see copyright certificate No. 1731154, IPC: A 47 J 37/04, publ. 07.05.92, Bull. No. 17), comprising a housing for fuel with grooves on its sides for setting skewers, skewers and a skewers rotation drive, including an electric motor and a gear transmission, the wheels of which are connected to the ends of the skewers when the latter are installed. The rotation of the skewers allows the kebab to be fried from all sides, however, the device does not have the ability to change the distance between the prepared portions and the heat source located at the bottom of the case.

A device for the preparation of barbecue (see patent for the invention No. 2236163, IPC: A 47 J 37/04, publ. 2004.09.20), comprising a housing, a group of skewers placed therein and a drive with a handle for rotating skewers, made in the form of a planetary friction gear. The design of the drive and the installation of skewers provide planetary movement of the prepared portions in the body volume, i.e. the device implements not only the axial rotation of the skewers, but also a change in the height of the latter relative to the heat source located at the bottom of the body, which is aimed at ensuring uniform frying of each portion of the kebab. However, the implementation of a manual rotation drive requires the constant presence and attention of the person serving the specified device.

The closest to the claimed solution is a device for heat treatment of food products (see utility model certificate No. 1210, IPC: A 47 J 37/06, publ. 07/07/93), containing a folding support, a fuel tray, two groups removable food holders and electric rotation drives for each of the groups. Mentioned holders are made in the form of skewers. One group of skewers is placed above the other and perpendicular to the last by means of two pairs of brackets mounted on the opposite walls of the pallet. The rotation drive of each of the groups includes a gearbox mounted on one of the brackets of the corresponding pair with output links according to the number of skewers in the group, and

connections of output links with skewers are made detachable. All brackets are removable and mounted on the walls of the pallet with the ability to control the installation height relative to the bottom of the pallet.

The advantages of the utility model according to St.-Wu No. 1210 include the possibility of increasing the number of simultaneously prepared portions and expanding the range of simultaneously prepared products by arranging two-level placement of removable product holders, as well as the ability to adjust the height of the holders relative to the bottom of the pallet, i.e. heat source. The disadvantage of this device is that to adjust the height of the group of skewers relative to the pallet during cooking, it is necessary to unscrew the fasteners of the brackets, move them and lock again. However, it is almost impossible to perform these actions with red-hot metal parts.

Utility Model Disclosure

The inventive utility model solves the problem of facilitating and simplifying the process of regulating the installation height of removable food product holders while improving human safety by eliminating direct contact of the latter with the hot parts of the device in the said regulation process.

The problem is solved due to the fact that in the device for heat treatment of food products containing a housing for fuel, two groups of removable food holders spaced apart in height, each connected with its own rotation drive, and two pairs of brackets, each of which is mounted on the respective opposite side walls of the housing and is designed to install one of the mentioned groups of removable holders, and at least one pair of brackets is removable and mounted as possible According to the claimed utility model, the removable brackets are made in the form of U-shaped racks, the ends of which are telescopically mounted in guides rigidly fixed to the side walls of the housing, while the device is equipped with a mechanism for vertical movement of U-shaped racks.

Unlike the prototype in the inventive device, the removable brackets are made in the form of telescopic support structures, namely in the form of U-shaped racks, the ends of which are telescopically mounted in rigidly mounted on the side

the walls of the guides, while the device is equipped with a mechanism for vertical movement of the U-shaped racks. The claimed combination of essential features is a new unknown from the prior art, therefore, the claimed device meets the criterion of "novelty."

The claimed solution excludes direct contact of the human operator with hot metal parts, as the operator interacts only with the governing bodies of the vertical movement mechanism, from which the specified movement through the system of elements of the mechanism is transmitted to the U-shaped racks. The racks are telescopically mounted in rails rigidly mounted on the housing, and therefore freely move up and down in them. Thus, the proposed solution provides the simplicity and speed of changing the distance between the heat source and the products placed on the removable holders during the preparation of the latter.

In the specific case of the device, the mechanism for the vertical movement of the U-shaped racks is made in the form of a lever mechanism, including a double lever, two connecting rods, a control element and a stopper. The double lever is formed by two rigidly connected simple single-arm levers, the so-called shoulders. The shoulders of the double lever are placed from the opposite ends of the housing and are rigidly fixed to the ends of the rod installed in the supports under the bottom of the housing with the possibility of rotation around its longitudinal axis. The connecting rods are also placed on the opposite ends of the housing. Each of them is pivotally connected at one end to the corresponding shoulder of the double lever, and the other to the corresponding U-shaped strut. The control is made in the form of a curtain with a longitudinal groove, in which the axis of one of the hinges connecting the connecting rod with the shoulder of the double lever is placed with the possibility of translational movement. The stopper is made in the form of a screw clamp located on the axis of rotation of the wings, fixing the angular position of the wings relative to the housing.

It is preferable to equip the body, the wings and the screw clamp with handles of heat insulating material. Handles of the case are used to carry the device. On the one hand, the rocker and screw handles make it easier to reinstall and fix, and on the other hand, their implementation of heat-insulating material is aimed at solving the task and allows to strengthen the technical result, namely, to completely eliminate human contact with the hot parts of the device.

Removable food product holders of one of the groups can be made in the form of skewers. The rotational drive of the skewers in a specific implementation includes a removable gear motor and a gear transmission containing a number of gears mounted on one of the respective brackets according to the number of skewers, each of which is made with an axial hole for installing the latter. One of the gears is configured to be connected to said gear motor.

Usually produced skewers intended for the preparation of barbecue, are flat pointed metal rods with a cross-section in the shape of a rectangle. To connect with skewers in order to ensure rotation of the last holes of the gears can be made cross-shaped. At the same time, each of the grooves forming the indicated shape of the hole is made proportional to the cross section of the ends of the skewers installed in them.

Another group of removable food holders can be made in the form of skewers. The skewer, like skewers, is a metal rod intended for frying meat over fire, only larger pieces or whole carcasses, which requires a greater spacing of skewers in space. The proposed skewer drive includes a removable gear motor and a gear reducer mounted on one of the U-shaped racks, including gears according to the number of skewers with axial holes for installing the latter. The gears are spaced apart in a vertical plane relative to each other and are connected by spurious gears, one of which is made with the possibility of connection with the aforementioned gear motor. The proposed use of removable gearmotors as electric motors greatly facilitates the drive as a whole, and also allows the interchangeable or alternate use of one gearmotor for both groups of holders.

The preferred version of the skewers is with a square cross section. The holes of the gears for connecting the ends of the skewers are preferably also square in shape of a reciprocal size.

In a specific case of execution, the group contains three skewers. For the most rational layout in space, the gears of the gearbox are spaced in the vertical plane along the vertices of the conditional isosceles triangle.

The device is preferably equipped with removable supports for mounting the housing, which is convenient for transporting the device. In the specific case of execution, the guides of the U-shaped racks are performed with protruding beyond the bottom of the housing

ends, while the supports are hollow and with the possibility of installation and fixation in them of the mentioned ends of the guides.

A device for heat treatment of food products (see Fig. 1) contains a rectangular housing 1 for fuel, removable supports 2, a pair of brackets 3 and 4, rigidly mounted on opposite side walls of the housing 1, a pair of removable brackets 5 and 6, mounted on two other opposite the walls of the housing 1, and two groups of removable product holders, made in the form of skewers 7 and skewers 8. Each group of removable product holders is equipped with its own rotation drive. The removable brackets 5 and 6 are made in the form of U-shaped racks, the ends of which are telescopically mounted in the rails 9. The device is equipped with a lever mechanism for vertical movement of U-shaped racks 5 and 6, including a double lever 10, connecting rods 11 and 12, the control element in the form of a wings 13 and a stopper made in the form of a screw clamp 14 placed on the axis of rotation of the wings 13.

The double lever 10 is formed by two simple one-arm levers 10 ′ and 10 ″ (so-called “shoulders”) rigidly connected to one another, which are placed from the opposite ends of the housing 1 and are rigidly fixed to the ends of the rod mounted to rotate about its longitudinal axis in supports 15 under the bottom of the housing 1 (see figure 2). The connecting rod 11 is pivotally connected at one end to the shoulder 10 'of the double lever, and the other to the U-shaped post 5. The connecting rod 12 is pivotally connected at one end to the shoulder 10 "of the double lever, and the other with a U-shaped rack 6 (see figure 3). The link 13 is made with a longitudinal groove 16, in which the axis of the hinge connecting the connecting rod 11 with the double lever arm 10 'is positioned for translational movement.

The drive rotation of the skewers 7 includes a removable gear motor 17 and mounted on the bracket 3 gear containing a number of gears

18, the number of which corresponds to the number of skewers 7 in the group. Each wheel 18 has an axial hole 19 of a cruciform shape, designed to connect with the end of the skewer 7. The rotary spindle drive 8 includes a gear reducer 20 mounted on a U-shaped rack 5, including gear wheels 21 according to the number of spit 8 with axial holes for installing the latter and removable gear motor 22 (see figure 1, figure 2). The gears 21 are spaced apart in a vertical plane relative to each other and are connected by parasitic gears 23, one of which is made with the possibility of connection with the gear motor 22.

The housing 1, the link 13 and the screw clamp 14 are equipped with handles 24, 24 'and 24 "for the operator, respectively, made of heat-insulating material.

Preparation of the device for work and preparation of products is as follows.

After transportation to the place of use, the housing 1 with the elements and mechanisms mounted on it is mounted on the supports 2, placing the ends of the guides 9 protruding beyond the bottom of the housing 1 in the cavity of the supports 2 and fastening them together by means of fixing fasteners 25, the gear motor 17 is connected to the gear wheel 18, and the gear motor 22 with gear 23.

In the housing 1 lay and then kindle fuel, for example, coal or firewood. The prepared pieces of the skewer semi-finished product are put on skewer 7. After receiving coals evenly burning without flame, the skewer 7 with the semi-finished products strung on them is sequentially inserted with pointed ends into the holes 19 of the gears 18, and the opposite ends of the skewers are freely placed in open semicircular grooves made on bracket 4.

The device allows you to simultaneously prepare several types of products, distributing the latter, depending on the desired processing mode, on the lower or upper group of holders.

So, for example, at the same time with barbecue, you can cook vegetables or other products, suggesting a more gentle frying mode compared to barbecue. Why they are strung on skewers 8, which are then alternately inserted with pointed ends into the openings of the gears 21, placing the opposite ends in the open semicircular grooves of the support elements 26 mounted on a U-shaped stand 6.

Turn on the gear motor 17, from which the rotation is transmitted to the gears 18 and then to the skewer 7. The semi-finished barbecue, rotating, evenly fried, while enveloping melted fat.

At the same time, the gearmotor 22 is turned on. The rotation from the output shaft of the latter is transmitted to the gear 23 and then to the gears 21 that rotate the skewers 8. The semi-finished products strung on skewers 8 are also uniformly fried while rotating.

For the preparation of large-sized products, such as meat, game or chicken (whole), it is necessary to provide a stronger heat, so the device is used by installing only one group - skewers 8.

If during cooking it became necessary to change the height of the skewers 8, for example, to reduce heat and prevent burning of the product, the following sequence of actions is carried out.

Rotating the handle 24 "loosens the screw clamp 14. Then, pressing the handle 24 'of the link 13 in the direction of the earth, rotate it relative to the axis of rotation. The axis of the hinge connecting the connecting rod 11 and the shoulder of the double lever 10' moves into the groove 16, the walls of which push the connecting rod 11. Upward, a U-shaped strut 5 is connected, connected to the other end of the connecting rod 11 and freely mounted in the rails 9. Using a double lever in the movement mechanism ensures simultaneous movement of the connecting rod 11 and the connecting rod 12 mounted from the counter the front end of the casing 1, and therefore the synchronization of movement of the U-shaped racks 5 and 6 with skewers 8 placed on them, which avoids distortions and jamming.After moving the racks to the desired size, the operator fixes the position of the link 13 relative to the casing 1 by twisting the screw clamp 14. Lowering the group of skewers 8 is carried out in a similar manner.

The mechanism of vertical movement of the U-shaped racks in the form of a lever mechanism provides ease of manufacture, installation and operation, as well as high reliability of the device.

The device is simple and convenient to use. It is characterized by wide capabilities and a large assortment of prepared products.
