DETAILED DESCRIPTION

[0019] The hot water heater of the present application will be further described below in conjunction with the accompanying drawings.

[0020] The hot water heater of the present application has intelligent control thermostatic function, as shown in Figure 1 and Figure 2 , comprising a heating water tank 2, a thermostatic water tank 3, an instant electric heater 4 and a heat pump system 5. The working principle of the instant electric heater 4 belongs to the prior art, for example, refer to the Chinese Utility Model Patent No. CN206281189U "Instant Electric Water Heater with Water Magnetic Device" and the Chinese Invention Patent Application No. CN105485921A "Instant Heating Device for Instant Heater". The heating principle of the heat pump system 5 belongs to the prior art. As shown in Figure 3 , the heating water tank 2 is provided with an electric heating tube 20, the thermostatic water tank 3 is connected to the heating water tank 2, the heat pump system 5 is provided with a condenser 52, and the condenser 52 is arranged in the thermostatic water tank 3, as shown in Figure 2 , the instant electric heater 4 is provided with an instant water inlet end 41 and an instant water outlet end 42, the thermostatic water tank 3 is connected to the instant water inlet end 41, and the thermostatic water tank 3 is provided with a temperature probe, which can be a thermocouple; the hot water heater of the present application further comprises a controller, which is electrically connected to the temperature probe and controls the electric heating tube 20, the heat pump system 5 and the instant electric heater 4.

[0021] The working principle of the hot water heater of the present application will be briefly described as follows: as shown in Figure 2 and Figure 5As shown, the electric heating tube 20 can heat the water flowing through the heating water tank 2, the heat pump system 5 works, the condenser 52 can heat the water flowing through the constant temperature water tank 3, that is, the instant electric heater 4 can heat the water flowing through the inside of the instant electric heater 4. When the user takes a bath using the water heater of the utility model, cold water (tap water) is first input to the heating water tank 2, the water body then flows to the constant temperature water tank 3, and then the water body flows through the instant electric heater 4, and then the water flow is discharged from the instant water outlet end 42; as the bath is carried out, the temperature probe monitors that the water temperature in the constant temperature water tank 3 is continuously reduced, when the temperature decreases by a certain amplitude, the controller controls the instant electric heater 4 to work, so that the water temperature does not rapidly decrease to make people feel cold, of course, the controller can also control the heat pump system 5 and the electric heating tube 20 to start working at this time, the water heater is in the maximum power working mode, and hot water can be quickly prepared, then, if the temperature probe monitors that the water temperature in the constant temperature water tank 3 has reached the set value, the controller can control the instant electric heater 4 to stop working, so as to improve the energy efficiency, if the temperature probe monitors that the temperature value is still higher than the set value after the instant electric heater 4 stops working, then the controller can control the heat pump system 5 and the electric heating tube 20 to stop working. When the bath is finished, the user closes the shower, and then the tap water supplements the heating water tank 2 and the constant temperature water tank 3, and the water temperature in the heating water tank 2 and the constant temperature water tank 3 is low, and the water heater works, when the water temperature gradually rises to the set value, the controller controls the electric heating tube 20, the heat pump system 5 and the instant electric heater 4 to stop working; the water heater can be manually set to enter the constant temperature standby mode, and the controller can only control the heat pump system 5 or the electric heating tube 20 to work, so that the hot water preparation speed is slow, but the energy efficiency is high, when the monitoring temperature of the temperature probe is lower than the set value, the controller controls the heat pump system 5 to start working according to the signal of the temperature probe, so that the monitoring temperature of the temperature probe rises to the set value; the water flow sensor can also be arranged on the water inlet end of the water heater, and the controller is electrically connected with the water flow sensor, when the water flow sensor monitors that the water flow stops, the controller judges that the bath is finished, and automatically enters the constant temperature standby mode, and the controller can only control the heat pump system 5 or the electric heating tube 20 to work, so that the hot water preparation speed is slow, but the energy efficiency is high.

[0022] The water heater of the utility model, when bathing, can realize instant heating effect, because the water heater of the utility model has the heat storage water structure of heating water tank 2 combined with constant temperature water tank 3, so the instant electric heater 4 can be set to lower power, and the total power of the water heater of the utility model can be set to lower power (compared with the instant water heater on the market); because the water heater of the utility model is in constant temperature standby mode and can only use the heat pump system 5 for constant temperature, it is beneficial to save electricity; because the electric heating tube 20 is arranged, when the air temperature is low, the water heater of the utility model can be kept at a higher temperature value; because the instant electric heater 4 is arranged, it is avoided to arrange a heat storage water tank with large size (compared with the air energy water heater on the market), and the water heater of the utility model occupies small space; it can be seen from the above that the water heater of the utility model has the advantages of energy saving and high efficiency, fast hot water output and easy arrangement, balanced performance and wide application range.
