  • Publication number: 20250169648
    Abstract: The present application pertains to the field of plasma grills, focusing specifically on an innovative plasma heating device integrated with such grills. This device includes an electric heating device including multiple electric heating components and a sophisticated circuit board equipped with necessary electrical components. Each electric heating component is distinguished by an electric output head and an associated electric connection rod that is electrically linked to the electric output head. The rod is securely fastened and connected to the circuit board, with all electric output heads uniformly aligned at the same horizontal level. A key advantage of the present application is its ability to consistently generate an electric arc between each output terminal and the fire gathering plate. This feature ensures a reliable and stable heating power delivery to the plate, which is essential for the effective operation of the plasma grill.

  • Publication number: 20250169647
    Abstract: The present application introduces an electric arc grill, which integrates a variety of components to facilitate efficient grilling. The grill includes an electric heating device, a fire gathering plate, a lifting device, and a grill carrier. The electric heating device includes an electric heating component and a circuit board, with the component including an electric output head and an electric connection rod that is electrically connected to the head and the circuit board. The lifting device, which is connected to the grounded grill carrier, supports the fire gathering plate through electrical connection. Positioned beneath the fire gathering plate, the electric output head is separated by a precise gap for the formation of an electric arc. Additionally, an oil receiving plate is incorporated between the electric output head and the circuit board. The plate is positioned to manage any oil residues, thereby maintaining the cleanliness and performance of the grill.

  • Patent number: 12232649
    Abstract: The present application pertains to an electric arc grill that integrates a range of components for enhanced functionality. Central to this grill is the electric heating device, which includes an electric heating component and a circuit board integrated with electric components. The electric heating component includes an electric output head and an electric connection rod that is securely attached to and electrically connected with the head, ensuring a stable connection to the circuit board. The grill is equipped with a lifting device that is affixed to and grounded by the grill carrier, facilitating the electrical connection with the fire gathering plate. This plate is positioned above the electric output head, creating a gap that is instrumental in generating the electric arc necessary for heating. The grill enables the fire gathering plate to be heated via electric arc, thereby providing a versatile cooking surface capable of frying, grilling, and baking.
