Technical Field

[0001] This utility model relates to the field of energy-saving device technology, specifically a composite energy-saving device integrating waste heat recovery. Background Technology

[0002] The integrated waste heat recovery barbecue grill composite energy-saving device is an innovative device designed to address the pain points of low heat utilization and high energy consumption in traditional barbecue grills. With the barbecue grill body as the core, it integrates waste heat recovery modules such as heat exchange tubes in areas where heat is easily lost, such as the outer perimeter of the grill cavity and the flue, forming a composite energy-saving structure of combustion heating - waste heat capture - secondary utilization.

[0003] When traditional barbecue grills are in operation, the high-temperature smoke carrying a large amount of heat is directly discharged into the air, which not only causes unnecessary energy loss, but also causes thermal pollution due to the diffusion of high-temperature exhaust gas. In the barbecue scene, the process of cleaning food and disinfecting tools requires additional heating of cold water, which further increases energy consumption. To address this, we propose a composite energy-saving device that integrates waste heat recovery. Summary of the Invention

Multiple square heat-conducting pipes are fixedly fitted onto the outer wall of the square water storage tank, and the multiple L-shaped air supply pipes are respectively connected to the multiple square heat-conducting pipes.

[0011] The beneficial effects of this utility model are: This invention utilizes a fan, square heat-conducting pipes, and a heat-conducting plate. The fan adsorbs the fumes generated during baking. The high-temperature fumes are filtered through a filter plate before entering the fan and exiting through multiple L-shaped air pipes in a guide shroud. The fumes then enter multiple square heat-conducting pipes, heating the cool water inside a square water tank. Simultaneously, the heat from the heating element is transferred to the heat-conducting plate, which in turn transfers heat to the square heat-conducting pipes, increasing their temperature and consequently raising the surface temperature of the square water tank. This accelerates the heating of the water inside the tank. After heating, a water pump is activated, and the hot water is extracted from the tank via a drain pipe. This eliminates the need for additional energy to heat cold water, reducing energy consumption and environmental pollution. Attached Figure Description
