Description

Waterway system of heating water heater and heating water heater Technical Field The application relates to the technical field of intelligent household appliances, in particular to a waterway system of a heating water heater and the heating water heater. Background As a key device for providing heating and domestic hot water in modern households and businesses, the stability and efficiency of the performance of the gas heating water heater are critical to the user experience. Currently, many gas heating water heaters integrate a water servo at their inlet valves in order to achieve precise control of water flow and maintain a constant outlet water temperature. This method adjusts the output water temperature by adjusting the inflow of tap water, aiming at providing a more comfortable and energy-saving use experience. However, since the water servo is directly connected with the water inlet pipe, the pressure born by the water servo is large, so that the eccentric problem of the inner valve core is easy to occur, and the accuracy of flow regulation is directly influenced. Secondly, setting up initial water velocity can be restricted in water inlet position with the water servo ware, when heating water heater ignition operation, the inside heat that accumulates of main heat exchanger can't distribute away rapidly, causes the water temperature to have apparent fluctuation. Therefore, the water servo is arranged on the water inlet valve of the heating water heater, so that the problems of lower accuracy of water outlet temperature and unstable water outlet flow are caused. Disclosure of utility model The embodiment of the application provides a heating water heater, which is used for solving the problems that a water inlet valve of the heating water heater is provided with a water servo, so that the accuracy of water outlet temperature is low and the water outlet flow is unstable. In a first aspect, the embodiment of the application provides a waterway system of a heating water heater, which comprises a living water pipeline, a first heat exchanger and a water server; The domestic water pipeline comprises a first water inlet, a first water outlet and a domestic hot water outlet, the first heat exchanger is connected with the domestic water pipeline, the water server is arranged between the first water outlet and the domestic hot water outlet, and water enters the first heat exchanger through the first water inlet to exchange heat and then flows out through the first water outlet, and then flows out from the domestic hot water outlet after flowing through the water server. As an optional implementation mode, the waterway system further comprises a water outlet valve, wherein the water outlet valve is arranged between the water server and the domestic hot water outlet or between the water server and the first water outlet. As an optional implementation manner, the water path system provided by the application comprises a connecting pipe arranged between the water outlet valve and the water server in the domestic water pipeline. As an optional embodiment, in the waterway system provided by the application, the connecting pipe is curved. As an optional implementation mode, the waterway system provided by the application further comprises a first temperature sensor, wherein the first temperature sensor is arranged between the water outlet valve and the water server and is used for detecting the water outlet temperature of domestic hot water.
