Description

The utility model relates to the field of preparing food products by heat treatment and can be used primarily for preparing shish kebab, lula kebab, portioned pieces of meat, sausages, sausages, mushrooms, and smoked bread.

A device for extracting contaminated air is known (Patent for invention RU No. 2481530, F24C 15/20 dated December 10, 2009), containing a housing with inlet and outlet openings. The housing has a fan and a filter in front of the fan. The device is located at a distance above the kitchen equipment, on the side of the inlet. The incoming air is sucked by a fan through a filter. On the exhaust side, the housing is connected to air ducts to remove contaminated air into the ventilation system or into the environment.

A device for extracting contaminated air is known (Patent for invention RU No. 2315242, F24C 15/20 dated 02/17/2003), containing a housing that is installed above the kitchen equipment. The housing contains inlet and outlet openings. The housing contains a fan. The incoming air is sucked in by a fan and passes through a filter located in the housing. After the filter, the air passes through the outlet to the air duct, which discharges the air into the ventilation system or into the environment. The filter is located at an angle relative to the housing. The filter is surrounded by a visor. In front of the filter there is a screen that partially allows air to pass through. Its dimensions are chosen so that a free suction gap remains, through which air that has not passed through the screen can penetrate to the filter. Fan speed is adjustable.

The closest analogue of the proposed utility model, taken as a prototype, is a device for extracting contaminated air (Utility model patent RU No. 143998, F24C 15/20 dated 02/19/2014), which contains a housing with inlet and outlet openings, an air duct connected to the outlet hole, a fan connected to the air duct, a filter located in front of the inlet, and a fan speed control device, according to the utility model, the housing contains a retractable box for moving the inlet to place it above the flow zone that comes from the open door of the oven, containing the housing with inlet and outlet openings.

The disadvantages of the closest analogue are the insufficiently effective capture of contaminants from the air and high energy consumption during operation of the device.

The technical objective of the utility model is to effectively capture pollutants from the air and low energy consumption during operation of the device.

The technical objective of the utility model is achieved by the fact that in a barbecue with natural draft, containing a fireproof heating chamber with a heat-reflecting lid, a smoke generating device in the form of a baking sheet with a grate for placing sawdust and a heating source, skewers for placing processed objects and a smoke-air mixture exhaust system, the the fact that the smoke-air mixture exhaust system has a channel formed at the top and bottom of containers for filling them with coolant, separated by heat-insulating partitions, and at the same time, the formed isolated sections of the upper container are autonomously connected to sources of coolant supply with the possibility of lowering its temperature along the movement of the smoke-air mixture , and the partitions of the lower container are made with a lower height than the side walls that form it with the possibility of overflowing coolant from one section to another.

The technical result of the utility model is the effective capture of pollutants from the air and low energy consumption during operation of the device.

In fig. Figure 1 shows a general view of a barbecue with natural draft.

A brazier with natural draft contains a fireproof heating chamber 1, in which there is a smoke generating device 2 in the form of a baking sheet with a grate for placing sawdust and a heating source. Heating chamber 1 has a heat-reflecting cover 3 and skewers 4 for placing processed objects. To remove and clean the smoke-air mixture, the grill is equipped with an exhaust system, which has a channel 5 formed from the top and bottom of containers 6 and 7 for filling them with coolant 8, separated by heat-insulating partitions 9 and 10. In this case, the formed isolated sections of the upper container 7 are autonomously connected through holes 11 to sources (not shown) of supplying coolant 8 with the possibility of lowering its temperature from t1 to t4 in the direction of movement of the smoke-air mixture. Partitions 9 of the lower container are made with a lower height than the side walls 12 that form it with the possibility of overflowing coolant 9 from one section to another.

A barbecue with natural draft works as follows.

In a fireproof heating chamber 1 barbecue with natural draft in a baking tray with a grate, sawdust is ignited using a heating source (for example, a heating element). The product is placed on skewers 4 for smoking. During the smoking process, the spent smoke-air mixture is removed by an exhaust system through channel 5. The movement of the smoke-air mixture occurs due to the fact that as it moves, the temperature of the containers 6 and 7 formed at the top and bottom, filled with coolant 8 and separated by heat-insulating partitions 9 and 10, decreases, thanks to the autonomous connection through holes 11 to sources (not shown) of cooling liquid 8. As a result, the smoke-air mixture is cooled, the moisture from it, together with the smoking components, condenses on the surface of the containers 7 and is thus cleaned.

A natural draft barbecue can be used as a waste incinerator or for similar industrial tasks with effective smoke purification.

A brazier with natural draft ensures effective capture of contaminants from the air and low energy consumption during operation of the device due to the implementation of a smoke-air mixture exhaust system in the form of a channel formed from above and below by containers for filling them with coolant, separated by heat-insulating partitions, forming isolated sections of the upper container autonomously connected to coolant supply sources with the possibility of lowering the temperature along the movement of the smoke-air mixture
