[0002] The energy-saving furnace that utilizes waste heat is a type of stove energy-saving technology. Its main purpose is to increase the stove's heat absorption, making it more fuel-efficient than traditional furnaces. Specifically, the energy-saving furnace is a three-dimensional space surrounded by furnace walls for fuel combustion. Its structural design and material selection are aimed at improving combustion efficiency and thermal energy utilization.

[0003] For different cuisines, the requirements for the furnace are different during the frying process. Some require a deeper furnace to lock the pot gas, and some require a shallower furnace to achieve quietness and energy saving. However, in the prior art, the reflector of the furnace generally cannot be adjusted in height, which makes it inconvenient to adjust the depth of the furnace and not convenient to adapt to the needs of different scenarios. For this reason, we propose an energy-saving furnace that utilizes waste heat. Utility Model Content
