AI Technical Summary
In the summer mode, when users finish using domestic hot water, the heating outlet valve of the existing wall-hung boiler closes, which prevents the circulating water from flowing to the external heating pipes. This causes an increase in water pressure in the internal pipes of the wall-hung boiler, leading to problems such as impact and abnormal motor noise.
A wall-hung boiler structure was designed, including a main heat exchanger, a plate heat exchanger, and a valve body. Through a movable switching shaft and a sealing ring, selective flow paths of hot water in different modes are achieved, preventing small circulating water from flowing to the heating water outlet. The switching shaft driven by a motor controls the sealing ring to selectively seal different outlets, thereby achieving effective circulation of hot water and heating.
This effectively avoids increased water pressure in the internal pipes of the wall-hung boiler, solves the problems of abnormal motor noise and increased water pressure in summer mode, and ensures stable operation of the equipment.
