Energy-saving quick-heating water heater
The invention belongs to the field of water heater equipment, and particularly relates to an energy-saving quick-heating water heater.
The water heater is a household appliance which is commonly used at present, the traditional water heater comprises an inner container, and hot water is stored in the inner container; in the using process, hot water flows out of the drain pipe, and meanwhile, cold water is supplemented into the inner container in time, so that the hot water in the inner container is neutralized by the cold water, the temperature of the hot water is gradually reduced, when people continuously use the hot water, the heating power of the water heater needs to be large enough to meet the normal use of the people, and therefore, the energy consumption is high; secondly, after the water heater is used, a large amount of hot water in the water heater cannot be effectively treated, and the heat can be slowly dissipated only in a heat conduction mode, so that the energy waste is caused.
To this end, we propose an energy-saving instant-heating type water heater to solve the above problems.
