Water heater system and control method thereof

Abstract

The invention discloses a water heater system and a control method thereof. The water heater system comprises a hot water tank, a hot water pipe, a cold water pipe, a water mixing pipe, a water circulating pipe, a controller, a temperature sensor and electronic valves, wherein the electronic valves are respectively arranged on the hot water pipe, the cold water pipe and the water mixing pipe; the water inlet end of the water circulating pipe is connected with the water inlet end of the water mixing pipe, and the water outlet end of the water circulating pipe is connected with the hot water tank; the temperature sensor is arranged on the water mixing pipe and used for detecting the outlet water temperature of the water mixing pipe; and the controller is connected with the temperature sensor and each electronic valve, and used for controlling the opening size of each electronic valve by combining the temperature sensor so as to adjust the outlet water temperature of the water mixing pipe. The water heater system can automatically adjust the outlet water temperature to a preset value, store and identify fingerprint information of a user, and set and control the outlet water temperature and the outlet water flow index of a water heater in a personalized mode according to the fingerprint information of the user; and the water heater system has the characteristics of flexibility and convenience in use, constant outlet water temperature, automaticity, safety, energy conservation and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a water heater system and a control method thereof. Background technique [0002] At present, conventional water heaters only have one cold water outlet pipe and one hot water outlet pipe. The cold water outlet pipe and the hot water outlet pipe are connected to the mixing valve. When the user uses water, the mixing valve switch is turned on to adjust the water temperature as required. Usually, the water discharged at the beginning is cold water, and the user needs to put the cold water for a period of time before hot water flows out. When turning on the water mixing valve switch, users often accidentally turn the water mixing valve to the hot water side, the hot water flowing out is very hot, and mild burns sometimes occur, which is not safe, but also causes water and energy Or, the user accidentally turns the mixing valve to the cold water side, and no hot water flows out a...

AI Technical Summary

Problems solved by technology

When turning on the water mixing valve switch, users often accidentally turn the water mixing valve to the hot water side. The hot water flowing out is very hot, and mild burns sometimes occur, which is not safe, but also causes water and energy damage. or, the user accidentally turns the mixing valve to the cold water side, and no hot water flows out after a long time, resulting in a waste of water resources

[0003] Therefore, the existing water heaters cannot automatically set and identify the hot water outlet temperature and water flow required by the user according to the user's needs.

In public hot water places such as hotels, hotels, business units and schools, it cannot meet the individual needs of different consumers
