[0002] A barbecue grill is a barbecue device that can be used to make barbecue foods such as grilled lamb kebabs, grilled meat, and grilled vegetables. According to different heat sources, barbecue grills can be divided into charcoal barbecue grills, gas barbecue grills, and electric barbecue grills; according to different barbecue forms, they can be divided into manual barbecue grills and automatic barbecue grills; according to different uses, they can be divided into household barbecue grills and commercial barbecue grills. Barbecue grills can be divided into charcoal barbecue grills, gas barbecue grills, and electric barbecue grills according to different heat sources. A charcoal barbecue grill uses solid charcoal as raw material and combustion heat as the heat source; a gas barbecue grill can be further divided into a liquefied gas barbecue grill and a natural gas barbecue grill, which has a combustion net and uses the combustion of liquefied gas and natural gas as the heat source respectively; an electric barbecue grill converts electrical energy into heat energy, and common forms of different media include electric heating tubes, quartz tubes, volcanic stones, etc.

[0003] The barbecue grills in the prior art are generally of an open structure, and the heat generated during barbecue will be directly discharged into the air.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: the present utility model provides an energy - saving and environmental - protection barbecue stove.

[0019] During the barbecue process, the high - temperature flue gas generated in the furnace chamber is sucked into the interior of the heat exchange chamber by an exhaust fan. The high - temperature flue gas contacts the heat exchange tube, thereby heating the cold water in the heat exchange tube. After the water in the heat exchange tube is heated, it becomes high - temperature steam and enters the steam tank. On the one hand, the temperature of the heat - exchanged flue gas drops and is discharged, reducing environmental pollution. On the other hand, the heating cylinder is heated by the high - temperature steam in the steam tank and can be used for boiling water, realizing waste heat recovery.

A handle is fixedly installed on one side of the barbecue grill 1. Universal wheels 13 are fixedly installed at the four corners of the bottom of the barbecue grill 1. By installing the universal wheels 13, it is convenient to move the barbecue grill. On the rear side of the upper surface of the barbecue grill 1, there is a heat exchange bin 4. On one side of the upper surface of the heat exchange bin 4, an exhaust pipe 14 is welded. A filter screen is fixedly installed inside the exhaust pipe. The cooled flue gas is discharged through the exhaust pipe 14;

[0030] An exhaust fan 5 and a heat exchange pipe 6 are fixedly installed inside the heat exchange bin 4. The heat exchange pipe 6 is of an "S" - shaped structure, which increases the contact area of the heat exchange pipe 6 and improves the heat exchange effect. A mounting plate 10 is fixedly installed at the lower end of the barbecue grill 1. A water tank 11 and a water pump 12 are fixedly installed on the upper surface of the mounting plate 10. The input end of the water pump 12 is connected to the water tank 11 through a water pipe, and the output end of the water pump 12 is fixedly connected to one end of the heat exchange pipe 6. The cold water in the water tank 11 is sucked into the interior of the heat exchange pipe 6 by the water pump 12, and the input end of the exhaust fan 5 is connected to one side of the furnace bin 2;

[0031] The fixed plate 7 is fixedly installed inside the recycling bin 3. A plurality of heating cylinders 8 are fixedly installed on the upper surface of the fixed plate 7. A steam groove 9 is formed inside the heating cylinder 8. The heating cylinder 8 is fixedly connected to the end of the exhaust fan 5 through a pipeline. During the barbecue process, the high-temperature flue gas generated in the furnace bin 2 is sucked into the heat exchange bin 4 by the exhaust fan 5. The high-temperature flue gas contacts the heat exchange pipe 6, thereby heating the cold water in the heat exchange pipe 6. After the water in the heat exchange pipe 6 is heated, it becomes high-temperature steam and enters the steam groove 9. On the one hand, the temperature of the flue gas after heat exchange drops and then is discharged to reduce environmental pollution. On the other hand, the heating cylinder 8 can be heated by the high-temperature steam in the steam groove 9 to boil water, realizing waste heat recovery.
