Description

Technical Field

[0001] This utility model belongs to the field of barbecue grills, and specifically relates to an automatic lifting and heat insulation device for a barbecue grill rack. Background Technology

[0002] Currently, most barbecue grills on the market use a manual adjustment system for the grill height. This means that the user manually changes the distance between the grill and the heat source using simple clips, hooks, or supports. This traditional method has many shortcomings in practical use.

[0003] First, manual adjustment during high-temperature grilling poses significant safety hazards, as users are highly susceptible to burns from the hot grill, oven body, or flaming flames. Second, manual adjustment makes precise and stable heat control difficult, leading to uneven heating of food, resulting in food that is either burnt on the outside and raw on the inside, or overcooked, affecting the quality of the food. Third, frequent manual operation is tedious, increasing the user's workload and exposing them to prolonged exposure to high temperatures and fumes, reducing the convenience and enjoyment of grilling. Furthermore, traditional grills generally lack effective side insulation, allowing significant heat loss in all directions, wasting energy and posing a heat radiation risk to the surrounding environment and people.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: To overcome the above shortcomings, the purpose of this utility model is to provide an automatic lifting and heat insulation device for a barbecue grill. Through a motor-driven lead screw lifting assembly, the height of the grill is automatically and precisely controlled. Users can operate it remotely, completely avoiding the risk of burns during manual adjustment, making operation safe and convenient. The automatic lifting structure operates smoothly, achieving stepless adjustment and precise height locking via the motor, thus enabling refined management of the heat and ensuring even heating of food, greatly improving the quality of the barbecued product. Simultaneously, the heat insulation baffles on both sides of the lifting grill, combined with the barrier effect of the back panel, effectively reduce heat radiation and loss towards the operator, improving both thermal efficiency and the comfort and safety of the operating environment.

[0006] Technical Solution: To achieve the above objectives, this utility model provides an automatic lifting and heat-insulating device for a barbecue grill rack, including a base, a back plate, a lifting assembly, and a lifting grill rack; the back plate is erected on the base; the lifting assembly is mounted on the back plate; the lifting grill rack is mounted on the lifting assembly and is controlled by the lifting assembly to move up and down; the lifting assembly includes a lifting mounting frame, a set of guide rails, a slider, a motor, and a lead screw; the lifting mounting frame is mounted on one side of the back plate; the guide rails are arranged side-by-side on the lifting mounting frame; the slider is mounted on the guide rails and is slidably connected to the guide rails; the motor is located below the lifting mounting frame and in the middle of the base; the lead screw is located between the upper end of the lifting mounting frame and the output end of the motor, and is rotated by the motor; the lead screw passes through the slider, and the two are threadedly connected; the lifting grill rack is connected to the slider and moves up and down with the slider to achieve lifting and lowering. The structure, which combines a lead screw and a slider, ensures smooth lifting and precise positioning, enabling automated control of the grilling height. The parallel guide rail design enhances the stability of the slider's operation, prevents swaying, and improves structural rigidity and service life. The motor is located in the middle of the base, resulting in a low center of gravity, reducing the risk of vibration and tipping, while also facilitating wiring and maintenance. The lifting mounting bracket is independently set up, making it easy to disassemble and replace the entire unit, thus improving maintenance efficiency.

[0007] Furthermore, a limit sensing component is also provided on one side of the lifting assembly; the limit sensing component includes a set of induction switches and a trigger plate; the induction switches are located beside the guide rail and are distributed vertically; the trigger plate is located beside the slider; the induction switches and the trigger plate work together to achieve limit sensing of the slider height. Through vertical limit sensing, the slider is prevented from exceeding its travel range, avoiding mechanical impact or motor stall, and improving the safety of the equipment.

[0008] Furthermore, the back panel is provided with a set of lifting openings; the lifting grill passes through the lifting openings and connects to the slider. The lifting mechanism is located on the rear side of the back panel, and the grill rises and falls from the front side, avoiding direct impact of oil and high temperatures on the transmission components and improving reliability.

[0009] Furthermore, the lifting grill is equipped with heat insulation baffles on both sides, which reduces the risk of users accidentally touching high-temperature areas and improves safety. At the same time, it helps to form local heat circulation, reduces heat loss, and thus improves grilling efficiency.

[0010] Furthermore, the back panel is provided with racks on both sides; the racks are L-shaped, and the long arm is horizontally positioned directly above the lifting grill, allowing for temporary placement of ingredients or tools before and after grilling, thus improving operational convenience.

[0011] Furthermore, a protective baffle is provided at the top of the back panel to prevent dust and debris from falling into the grill or transmission mechanism, thereby improving food safety and equipment reliability.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This utility model relates to an automatic lifting and heat insulation device for a barbecue grill. Through a motor-driven screw lifting assembly, the height of the grill is automatically and precisely controlled. Users can operate it remotely, completely avoiding the risk of burns when adjusting manually. The operation is safe and convenient. 2. This utility model provides an automatic lifting and heat insulation device for a barbecue grill. The automatic lifting structure operates smoothly and the height is infinitely adjustable and precisely locked through a motor, thereby achieving precise management of the heat and ensuring that the food is heated evenly, which greatly improves the quality of the barbecue product. 3. This utility model provides an automatic lifting and heat insulation device for a barbecue grill. The heat insulation baffles on both sides of the lifting grill, combined with the blocking effect of the back plate itself, effectively reduce the radiation and loss of heat towards the operator, thereby improving thermal efficiency and enhancing the comfort and safety of the operating environment.
