Description

Technical Field

[0001] The utility model relates to the technical field of electric heating barbecue equipment, in particular to an electric heating type smokeless barbecue oven structure. Background Art

[0002] In the prior art, a barbecue grill is a type of grilling equipment used to prepare grilled foods such as kebabs and barbecued meats. Barbecue grills can be categorized into three types: charcoal grills, gas grills, and electric grills. Gas and electric grills are popular for their smoke-free and product-friendly design. Electric grills typically consist of a furnace body and a grill. The furnace body has a cavity with an open top, which houses heated charcoal or an electric heating tube. The grill is mounted within the top opening of the furnace body. During use, food is placed on the grill, and the heat generated by the burning charcoal or the electric heating tubes is used to cook the food. However, in prior art barbecue grills, the oil produced by the food during cooking, as well as the cooking oil and seasonings used during cooking, can directly fall into the hot charcoal fire or the electric heating tubes, generating a large amount of fumes. This can lead to the production of carcinogens in the grilled food, making it environmentally unfriendly and highly susceptible to health risks. Furthermore, prior art barbecue grills can only cook food from the bottom, resulting in uneven heating of the food. Frequent manual turning of the food during cooking is laborious and time-consuming.

[0003] The Chinese utility model patent with application number: 202221720511.7 discloses a smokeless, energy-saving, high-temperature barbecue grill, including an operating surface, a solar panel, a smoke exhaust device and a transparent panel. The bottom of the operating surface is fixedly connected to a bottom support frame, and a battery box is fixedly installed inside the bottom support frame. The surface of the operating surface is provided with a mounting groove, and an electric heating device is fixedly installed at the bottom of the mounting groove, and the mounting groove is engaged with the baking tray. The top of the operating surface is fixedly provided with a top support frame, and the back of the top support frame is fixedly connected to a solar panel, and a smoke exhaust device is installed on the top of the top support frame. The smoke exhaust device is connected to the top support frame through an air duct, and a filter element for filtering smoke is provided inside the smoke exhaust device. However, this type of smokeless energy-saving high-temperature barbecue grill eliminates smoke by exhausting and purifying the smoke, but it still produces oil smoke during the barbecue process, causing the barbecued food to produce carcinogens, which is environmentally unfriendly and affects people's health. In addition, during the barbecue process, it is necessary to manually turn the food frequently, which is troublesome and laborious. The height of the heating structure cannot be adjusted, making it inconvenient to disassemble and assemble the barbecue grill components. Utility Model Content
