AI Technical Summary
Traditional gas-fired heating and hot water boilers lack an internal tank cleaning structure, resulting in complex and incomplete cleaning operations. The accumulation of dirt affects the quality of hot water and the lifespan of the equipment.
A gas-fired heating and hot water boiler with an easy-to-clean inner tank has been designed. It includes components such as a motor, lead screw, turntable, and cleaning blade. The motor drives the lead screw to rotate, which in turn drives the turntable to move spirally along the inner wall of the tank. The cleaning blade is used to achieve a thorough cleaning. It is also equipped with a sound insulation layer and a heat insulation layer to improve the user experience.
It achieves efficient cleaning of the inner tank, facilitates maintenance, reduces noise and heat loss, extends equipment life, and improves hot water quality and ease of use.
