AI Technical Summary
Due to the lack of a contact structure that fully drives the air to the heating mechanism, the existing hot air furnace has low air heating efficiency and the heat transfer device is not sealed enough, resulting in waste of energy.
A hot air furnace is designed including a heating box, an intake box, a hot air duct, an intake fan blade, a spiral intake pipe, a heating box and a ventilation box. The suction fan blade sucks air into the heating box through the spiral intake pipe, and enters the heating box through the round air inlet and the annular air intake groove, so that the air is close to the heating pipe and improves heating efficiency. The heated air enters the hot air duct through the ventilation box to avoid heat loss.
Through improved structural design, the heating efficiency of air is improved, the loss of heat is reduced, and the energy utilization rate and lower energy consumption are achieved.
