Description
Technical Field

Background
The water heater is a device which can increase the temperature of cold water into hot water in a certain time by various physical principles. According to different principles, the water heater can be divided into an electric water heater, a gas water heater, a solar water heater, a magnetic water heater, an air energy water heater, a heating water heater and the like.
At present, the electric water heater has two types, namely a water storage type electric water heater and an instant heating type electric water heater, the water storage type electric water heater has a large volume, so that the installation occupied space is large, and the same amount of cold water needs to be injected along with the discharge of hot water in a water storage tank, so that the subsequent hot water temperature is lower, and the subsequent use of the water heater is influenced. 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 and needs to have larger processing power, thus easily causing circuit overload. In order to solve the above problems, an integrated water heater having both a storage type electric water heater and an instant water heater has been used.
The existing integrated water heater with the water storage type electric water heater and the instant water heater is generally characterized in that a water source is mixed with stored water led out from a water storage tank, and then the stored water is output after being heated by the instant water heater, so that the highest required power of the instant water heater is effectively reduced, and the instant water heater is arranged, so that the volume of the water storage tank can be reduced, the occupied space of the water heater is effectively reduced, and the water heater is more energy-saving under the condition that the output temperature is more stable. However, in the process of water outlet of the water storage tank type water heater, the same amount of cold water needs to be injected, so that the temperature of mixed water output subsequently is gradually reduced, and therefore, hot water of the water storage type electric water heater cannot be discharged by 100%, and the hot water output rate is about 60%, so that the volume of the water heater is not greatly reduced; secondly, the heating power of the instant water heater also needs to be continuously increased along with the reduction of the mixed water temperature in the using process, so that the maximum heating power is not reduced, and the hidden trouble of circuit overload still exists.
Therefore, the design can effectively improve the hot water output rate of the water tank type water heater, thereby effectively realizing the great reduction of the volume; the utility model also discloses a constant-temperature integrated high-efficiency water heater which can effectively control the maximum heating power of the instant water heater so as to effectively prevent circuit overload.
