Description

Technical Field

[0001] The utility model relates to a carbon-based overhead barbecue grill, which can enrich the ways of food processing. It belongs to the technical field of barbecue grills, and particularly relates to a barbecue grill with a hollowed-out bottom furnace body cooperating with an overhead carbon plate, which can realize multi-directional air circulation in the furnace body, make the carbon burn fully, effectively reduce the carbon consumption and facilitate ash cleaning. Background Technique

[0002] Barbecue is a food processing process in which meat skewers or vegetarian skewers are grilled on a grill with a heat source. It is generally divided into electric grilling or charcoal grilling. Traditional barbecue grills are mostly of an integrated structure, which is relatively bulky and not convenient to carry outdoors. In existing assembled barbecue grills, the joints are prone to shaking due to uneven force. In order to make the assembled barbecue grill receive uniform force everywhere to ensure the stability of the furnace body, generally no other structures for processing food are added to the assembled furnace body. The barbecue grill can only perform simple barbecuing, with insufficient food richness and unable to meet people's diverse needs for food consumption. Moreover, the heat generated inside the barbecue grill is only used for grilling skewers. In order to make the skewers on the grill receive uniform heat, the skewers need to be constantly turned, which results in a limited number of skewers that can be grilled simultaneously on one barbecue grill, thus causing a great waste of heat. Publication No. CN116421072A discloses a three-in-one barbecue grill, including a Beggar's Chicken baking cylinder, a barbecue grill and a heat source. The heat source is arranged inside the barbecue grill and provides heat energy for the food inside the Beggar's Chicken baking cylinder and the skewers on the barbecue grill at the same time. The Beggar's Chicken baking cylinder is arranged inside the barbecue grill, and the food inside the Beggar's Chicken baking cylinder is baked and cooked by using the heat source inside the barbecue grill. The barbecue grill is of an inner and outer double-layer structure, and there is a gap between the inner shell and the outer shell of the barbecue grill. This barbecue grill is of an integrated structure, relatively bulky and not convenient to carry outdoors. Moreover, this barbecue grill bakes food by means of electric heating, and an additional power source needs to be carried outdoors, making it inconvenient to use. Publication No. CN220089257U discloses an assembled barbecue grill, including a pair of long side plates, a pair of short side plates, an ash pan and a charcoal support. At least two first support flanges are provided on both sides of the long side plate, and the gap between two adjacent first support flanges forms a flange groove. Positioned on both sides of the short side plate are buckles corresponding to the flange groove in position and several second support flanges. The long side plate and the short side plate are connected in a snap-fit manner through the first support edge, the buckle and the second support flange to form a frame. The ash pan is detachably connected inside the frame, and the charcoal support is embedded in the ash pan. In this assembled barbecue grill, the joints are prone to shaking due to uneven force. In order to make the assembled barbecue grill receive uniform force everywhere to ensure the stability of the furnace body, generally no other structures for processing food are added to the assembled furnace body. The barbecue grill can only perform simple barbecuing, with insufficient food richness and unable to meet people's diverse needs for food consumption. Moreover, the heat generated inside the barbecue grill is only used for grilling skewers. In order to make the skewers on the grill receive uniform heat, the skewers need to be constantly turned, which results in a limited number of skewers that can be grilled simultaneously on one barbecue grill, thus causing a great waste of heat.Publication number CN217885799U discloses a portable assembled barbecue grill, comprising a first sheet, a second sheet, a first support sheet and a second support sheet; the bottom ends of the first sheet and the second sheet are spliced ​​and fixed to form a V-shaped structure with a closed bottom end; the first support sheet and the second support sheet are correspondingly arranged on both sides of the V-shaped structure, and the first support sheet and the second support sheet are symmetrically provided with first slots inclined from the outside to the inside on both sides, and the first sheet and the second sheet are respectively provided with second slots that are plugged and matched with the first slots on both sides, and the first sheet and the second sheet are correspondingly inserted on both sides of the first support sheet and the second support sheet to form an annular structure. The joints of the barbecue oven are prone to shaking due to uneven force. In order to make the force uniform at all parts of the barbecue oven after splicing to ensure the stability of the oven body, other structures for processing food materials are generally not added to the spliced ​​oven body. The barbecue oven can only perform simple barbecue, and the richness of food materials is not enough to meet people's demand for diverse food materials. The heat generated in the barbecue oven is only used for roasting skewers, and in order to make the skewers on the grill evenly heated, the skewers need to be constantly turned over, which leads to a limited number of skewers that can be roasted on a barbecue oven at the same time, thereby causing a huge waste of heat.

[0003] In order to improve the above problems, the applicant filed a Chinese utility model patent application entitled "A barbecue stove". The barbecue stove bottom plate, barbecue stove side plate and barbecue stove end plate are staggered and spliced ​​to improve the support stability of the stove body on the outer cylinder. After adding the outer cylinder, the stove will not shake or even collapse due to uneven force, which increases the richness of the food while ensuring the safety of the barbecue. However, in actual use, the applicant found that the air circulation in the barbecue stove is not smooth, especially the space in the stove where the outer cylinder is installed. The carbon space on both sides is narrow, and most of the carbon is not fully burned. In order to provide installation space for the outer cylinder, the overall depth of the barbecue stove is relatively large, and more carbon needs to be placed in the barbecue area to allow the heat to reach the food. The overall carbon consumption of the barbecue stove is large. Utility Model Content

[0004] In order to improve the above situation, the utility model provides a carbon-based overhead barbecue grill with a hollow bottom formed by the cross-engagement of the barbecue grill side plate and the barbecue grill end plate. The carbon plate is overhead and arranged on the furnace body, and the ventilation groove is used to realize the multi-directional circulation of air in the furnace body, so that the carbon is fully burned, the carbon consumption is effectively reduced, and the barbecue grill is easy to clean. The circulating air drives the heat to flow in multiple directions in the furnace body, so that the heat distribution in the furnace body is more uniform, and then the food is heated more evenly. The fully burned carbon can reduce the generation of smoke and harmful gases.
