The invention relates to electrical engineering and can be used in electric appliances and equipment for public catering, in particular in devices for heating and cooking foods such as chicken, meat, etc.

Known rotary grills, comprising a housing, inside which is placed the heaters, the rotation of food products (carousel) and the actuator (see US patents 5445064, US 5429042, publishing, 1995, MPK7 A47J 37/04) (1).

Design data grills complex, which leads to higher economic costs in the manufacture and operation of these grills.

The closest analogue of the present invention is a rotary grill, comprising a housing with an opening glass door, inside of which there are heaters and carousel, driven in rotation by an electromagnetic actuator, AC, consisting of the horizontal axis, the edges of which are fixed disks suspended on them baskets for food (see A.S. SU 1717094 A1, IPC 7 A47J 37/04, publication 07.03.1992) (2).

In the famous grill is not provided with a special device for braking the wheel. This leads to the fact that when removing the finished product is spontaneous turning of the carousel.

The disadvantage of this grill is that as the drive COI is lsout special motor and gearbox, connected to each other by the coupling. Such motors are much complicate and increase the cost of installation cost.

The technical object of the present invention is to eliminate the disadvantages of the nearest analogue, namely improving the convenience of use of the grill by providing reliable braking carousel, and also to simplify the design and increase durability and reliability of the actuator and, hence, the entire grill.

The problem is solved in that in the carousel grill, comprising a housing with at least one opening door, inside of which there are heaters and carousel, driven in rotation by an electromagnetic actuator, AC, consisting of the horizontal axis, the edges of which are fixed disks suspended on them baskets for food, as the drive is used the motor-gearbox with spur gears, and the power supply circuit of the motor-reducer entered the rectifier included with switch to turn off the actuator to effect the braking of the rotor.

The door of the grill preferably made of glass.

Basket for food, perform lattice and hung on pins rigidly mounted on the disks.

In the use of standard gear motor made is based asynchronous reversible motor, in which the gear is a cylindrical gear, simplifies the design and increases the efficiency of the grill.

Introduction to the food chain winding gear motor rectifier when the switch is off mode "rotation" mode "braking" causes the flow through the control winding of a constant current, resulting in electromagnetic non-contact brake rotor gear motor.

The invention is illustrated by drawings and electric schemes.

Figure 1 presents a General view of the rotary grill.

Figure 2 presents the electrical power circuit of the motor-reducer in the "rotation".

Figure 3 presents the electrical power circuit of the motor-reducer mode "braking".

Carousel grill (see figure 1) consists of a housing 1, made of stainless steel with opening glass door 2. Inside the housing 1 has a heating chamber in which is placed a tubular electric heaters (heating Elements) 3 with reflective screens 4 and carousel, consisting of a horizontal axis (bars) 5, the edges of which are fixed two disks 9, which by means of probes 10 is suspended lattice basket 11 which loads them with food.

Axis 5 is driven from the gear motor 8 through the cylindrical gears 6, 7.

Figure 2 shows the electrical diagram of p is Tania gear motor in rotation mode when the rectifier (not shown). The diagram shows the motor-reducer 12, for example a motor RD-09, the capacitors 13 and 14.

Figure 3 shows the electric circuit of the power gear motor in the braking mode, which presents the rectifier 15 and the capacitor 16.

Carousel grill works as follows.

After loading the lattice baskets 11 food close the glass door 2, include the heaters 3 and the geared motor 8, which through gears 7, 6 causes the rotation axis 5 of the carousel.

After the end of the cooking process food off mode "rotation" switch (not shown), which when the switch is in the "inhibition" includes the power supply circuit of the motor-reducer 8 rectifier 15 and generates a DC voltage on the motor winding, creating the effect braking of the rotor, preventing the spontaneous turning of the carousel when removing from it the finished product.

We offer rotary grill differs from the closest analogue, because it can be used as a motor, the motor-reducer type RD-09, produced by domestic industry.

The presence in the food chain gear motor rectifier and switch included in the switch off mode "rotation" mode "braking" grill, ensures formation of electromagne the aqueous contactless braking, which is more reliable and durable than mechanical contact inhibition. These advantages of the present invention allow to obtain significant economic benefits.

1. Carousel grill, comprising a housing with at least one door, inside of which there are heaters and carousel, driven in rotation by the actuator, consisting of a horizontal axis, the ends of which are fixed disks suspended on them baskets of food products, characterized in that the actuator used the geared motor and the power supply circuit of the motor-reducer entered the rectifier and switch included in the moment of switching off of the grill to ensure the formation of electromagnetic non-contact brake.
