[0051] In the embodiments of the present application, after the preheating function of the water heater is started, first the water pump of the water heater starts. After the water pump starts, water enters from the water inlet. After the combustion conditions are met, combustion is started. The water heater can control the opening degree of the gas inlet valve based on the target set temperature, thereby controlling the gas output of the water, and thus controlling the combustion.

[0052] Step S102, when it is determined that the heated water is to be delivered to the first water usage point, control the water heater to stop heating.

[0053] In the embodiments of the present application, a temperature sensor may be provided at the first water - using point.

[0054] In some embodiments, the electronic device can determine the amount of hot water heated by the water heater, and can pre - store the cumulative water consumption of the heated water delivered to the first water - using point.

[0057] Embodiment 2:

[0058] Based on the connection structure of the foregoing water heater, embodiments of the present application provide a control method. Figure 3 It is a schematic flowchart of the implementation of a control method provided by an embodiment of the present application, as Figure 3 shown, including:

[0059] Step S201, when the pre - heating function is started, control the water heater to heat the water flowing into the water inlet based on the target set temperature.

[0060] In the embodiments of the present application, a pre - heating function button may be provided on the water heater, and the user can click or press the pre - heating function button to start the preset function of the water heater.

[0061] In some embodiments, the user can control the start of the water heater pre - heating function through the APP.

[0062] In the embodiments of the present application, the target set temperature can be configured. In some embodiments, the target set temperature may be set by the manufacturer when the water heater leaves the factory.

[0063] In the embodiments of the present application, the water heater may be a gas water heater, a wall - hung boiler water heater, etc.

[0064] In the embodiment of the present application, after the preheating function of the water heater is started, first, the water pump of the water heater is started. After the water pump is started, water is inlet from the water inlet. After the combustion conditions are met, combustion is started. The water heater can control the opening degree of the gas inlet valve based on the target set temperature, thereby controlling the gas outlet and thus controlling the combustion.

[0065] Step S202: Determine the amount of hot water after heating.

[0066] In the embodiment of the present application, the water heater can determine the amount of hot water of the heated water based on the flow rate at the water outlet or the water inlet.

[0067] Step S203: When the amount of hot water is greater than or equal to a preset threshold, determine to deliver the heated water to the first water usage point.

[0068] In the embodiment of the present application, if the amount of hot water is less than the preset threshold, it is considered that the hot water has not reached the first water usage point, and heating needs to continue.

[0069] In some embodiments, before step S203, the method further includes:

[0070] Step S1: Obtain the inlet temperature of the tap water.

[0071] In the embodiment of the present application, a temperature sensor can be provided at the water inlet of the water heater. The electronic device is communicatively connected to the temperature sensor, and the inlet temperature of the tap water is obtained through the temperature sensor.

[0072] Step S2: Determine the deviation value of the amount of hot water based on the inlet temperature and the preset inlet temperature.

[0073] In the embodiment of the present application, when the inlet temperature is less than the preset inlet temperature, it is determined that the deviation value is greater than 0; when the inlet temperature is greater than the preset inlet temperature, it is determined that the deviation value is less than 0.

[0074] In the embodiment of the present application, the greater the difference between the inlet temperature and the preset inlet temperature, the greater the absolute value of the deviation value. A corresponding relationship between the difference and the deviation value can be established in advance. When the inlet temperature is determined, the difference can be determined, and then the deviation value can be determined based on the difference and the corresponding relationship.

[0075] Step S3: Determine the preset threshold based on the deviation value and the cumulative water consumption, where the cumulative water consumption is determined based on the preset inlet temperature.

[0076] In the embodiment of the present application, the preset threshold can be obtained by adding the deviation value to the cumulative water consumption.

[0077] In the embodiment of the present application, the cumulative water consumption can be determined based on the following steps:

[0078] Step S11, when water comes out from the first water usage point, control the water heater to heat the water flowing into the water inlet based on the target set temperature, where the temperature of the water at the water inlet is the preset inlet temperature.

[0079] In the embodiment of the present application, the user can turn on the faucet at the first water usage point, and at this time the water heater starts heating.

[0080] Step S12, obtain the outlet water temperature of the water at the first water usage point.

[0081] In the embodiment of the present application, the outlet water temperature of the water at the first water usage point can be obtained through a temperature sensor.

[0082] Step S13, when the outlet water temperature reaches the target set temperature, control the water heater to stop working, and record the water inflow volume from the moment when water comes out from the first water usage point to the moment when the water heater stops working;

[0083] Step S14, determine the water inflow volume as the cumulative water usage volume.

[0084] Step S204, when it is determined that the heated water is delivered to the first water usage point, control the water heater to stop heating.

[0085] In the embodiment of the present application, a temperature sensor can be set at the first water usage point. When the temperature of the water at the first water usage point reaches the target set temperature, it can be determined that the heated water is delivered to the first water usage point.

[0086] In some embodiments, the electronic device can determine the hot water volume of the hot water heated by the water heater, and can pre-store the cumulative water usage volume of the heated water delivered to the first water usage point. When the hot water volume reaches the cumulative water usage volume, it is determined that the heated water is delivered to the first water usage point.

[0087] In the embodiment of the present application, in order to make the water hot when the first water usage point is turned on and cold when the second water usage point is turned on, so when it is determined that the heated water is delivered to the first water usage point, control the water heater to stop heating.

[0088] A control method provided by the present application, when the preheating function is started, controls the water heater to heat the water flowing into the water inlet based on the target set temperature; determines the hot water volume of the heated hot water; when the hot water volume is greater than or equal to the preset threshold, determines that the heated water is delivered to the first water usage point, and controls the water heater to stop heating, which can achieve hot water on demand at the first water usage point and cold water on demand at the second water usage point.

[0089] Embodiment III:

[0090] Based on the foregoing embodiments, an embodiment of the present application provides a gas hot water system, which includes a gas water heater, several water use points, and a water supply pipeline connecting the gas water heater and the water use points. The gas water heater includes a controller, a heat exchanger, a water pump, a water inlet, and a water outlet. The water pump is arranged at the water inlet, the inlet of the water pump is connected to the tap water pipeline, and the water pump is signal-connected to the controller. An inlet water temperature sensor and an outlet water temperature sensor, both signal-connected to the controller, are respectively arranged at the water inlet end and the water outlet end of the heat exchanger; the water supply pipeline includes a cold water pipeline that is branched from the tap water pipeline to the water use points in parallel, and a hot water pipeline that is branched from the water outlet of the gas water heater to the water use points in parallel. A check valve that allows water to flow from the hot water pipeline to the cold water pipeline is arranged at the farthest ends of the hot water pipeline and the cold water pipeline. Through this gas hot water system, the problem that cold water cannot be used after preheating is completed in the case of no return water pipeline can be solved, and instant hot water and instant cold water can be achieved at the same time.

[0091] First, it is necessary to obtain the heat transfer situation of the ambient hot water pipeline and the environment where the pipeline is located. Enter the environmental test mode according to the preset steps of the program. Open the farthest hot water faucet (the first water use point in the above-mentioned embodiment), and the whole machine burns and heats according to the set temperature T. When the water outlet temperature at the farthest hot water point reaches T, close the faucet. Record the cumulative water volume L_sum and the current inlet water temperature Tin_0 at this time.

[0092] In an embodiment of the present application, when the preheating start condition is met, the water pump is started, and when the combustion condition is met, combustion is started, and the gas output is controlled according to the target temperature T_set set by the user. The water volume L is calculated cumulatively during the process.

[0093] In an embodiment of the present application, when L > L_sum + L△, the shutdown condition is reached, where L△ is a deviation value.

[0094] In an embodiment of the present application, L△ = f(Tin_0, Tin). The current ambient temperature is inversely deduced based on the current inlet water temperature, which in turn affects the heat dissipation and heat transfer of the hot water pipeline. The lower the inlet water temperature, the larger L△. Each time the preheating function is performed, the current inlet water temperature Tin is compared with Tin0. When Tin is equal to Tin_0, L△ = 0; this means that the preheating function is completed as long as the cumulative combustion quantity L > L_sum.

[0095] L△ represents the deviation value at different temperatures. When the temperature is higher than Tin_0, L△ is a negative number.

[0096] In an embodiment of the present application, it is necessary to enter the environmental test mode, and there will be preset L_sum and Tin_0 inside the program; the preheating function is controlled according to the measured parameters.

[0097] The control method provided by the embodiments of the present application can avoid the problem of equipment damage in the cold water pipeline and over-temperature at the water usage point caused by hot water in the entire pipeline.
