[0040] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0041] Example 1

[0042] This embodiment provides a control method for a water heater, wherein the water heater includes a plurality of water outlet pipes; each water outlet pipe corresponds to a different water outlet temperature and a water outlet valve, such as Figure 1 As shown, the control method includes:

[0043] S101, obtaining the water flow of all water outlet pipes.

[0044] Specifically, in this embodiment, a water flow sensor may be installed in each water outlet pipe, and the water flow in the water outlet pipe may be obtained through the water flow sensor.

[0045] S102: Determine the target number of water outlet pipes in operation based on the water flow rate.

[0046] Specifically, in this embodiment, when it is detected that the water flow in the water outlet pipeline is not 0, it is considered that the water outlet pipeline is in operation.

[0047] S103, matching the corresponding hot water control mode according to the target quantity; the hot water control mode is set according to the outlet water temperature and the outlet valve.

[0048] When the target quantity is a single one, step S103 specifically includes heating the water in the working water outlet pipeline to a corresponding water outlet temperature.

[0049] like Figure 2 As shown, when the target quantity is multiple, the step S103 specifically includes:

[0050] S1031. Heat the water in the working water outlet pipeline to a target water outlet temperature, and use the water outlet pipeline corresponding to the target water outlet temperature as the target water outlet pipeline.

[0051] S1032. Adjust the mixing valve of the secondary water outlet pipeline until the water in the secondary water outlet pipeline reaches the corresponding water outlet temperature.

[0052] The target outlet water temperature is the highest outlet water temperature among the outlet water temperatures corresponding to the outlet water pipes in operation; the secondary outlet water pipes are the outlet water pipes in operation except the target outlet water pipes. Figure 3 As shown, specifically, in this embodiment, step S1032 specifically includes:

[0053] S10321. Measure the temperature of water in the secondary water outlet pipe.

[0056] Specifically, in this embodiment, the target opening is calculated according to the following formula:

The temperature of the water in the secondary water outlet pipeline is detected by the temperature sensor, and the temperature of the water in the secondary water outlet pipeline is sent to the water heater through the wireless communication module. The water heater calculates the target opening of the mixing valve of the secondary water outlet pipeline according to the temperature of the water in the secondary water outlet pipeline, the outlet water temperature corresponding to the secondary water outlet pipeline and the target outlet water temperature, and sends the target opening to the wireless communication module of the secondary water outlet pipeline through a control instruction to control the opening of the mixing valve.
