The instant water heater heats flowing water flow when in use, has the characteristic of stable water outlet temperature, but directly heats cold water to the water outlet temperature, needs to have larger processing power, and is easy to cause circuit overload. In order to solve the above problems, an integrated water heater having both an electric water storage heater and an instant water heater is being used.
The existing integrated water heater with the water storage type electric water heater and the instant heating water heater generally mixes a water source with stored water led out from the water storage tank, and then the stored water is heated by the instant heating water heater and then output, so that the highest required power of the instant heating water heater is effectively reduced, and the volume of the water storage tank can be reduced due to the arrangement of the instant heating water heater, the occupied space of the water heater is effectively reduced, and the energy is saved under the condition that the output temperature is more stable. However, in the water outlet process of the water storage tank type water heater, the same amount of cold water needs to be injected, so that the water temperature of the mixed water which is output later gradually decreases, firstly, the hot water of the water storage type water heater cannot be discharged 100%, and the hot water output rate is about 60%, so that the volume of the water heater is not reduced greatly; secondly, in the using process of the heating power of the instant water heater, the heating power needs to be continuously increased along with the reduction of the mixed water temperature, so that the maximum heating power is not reduced, and the hidden danger of overload of a circuit still exists.
Therefore, the design can effectively improve the hot water output rate of the water tank type water heater, so that the volume is effectively reduced greatly; the control method of the constant temperature integrated high-efficiency water heater can effectively control the maximum heating power of the instant water heater, thereby effectively preventing the overload of the circuit.
