And when the real-time temperature of the hot water is detected to be more than or equal to the second temperature in the preset time period, determining that the real-time temperature of the hot water meets the sterilization condition.

Optionally, the temperature detecting device corresponding to the heating branch may be disposed on the heating branch, or may be disposed at a water inlet of the hot water branch, or may be disposed at a connection between the hot water branch and the heating branch.

Alternatively, there may be a corresponding relationship between the first temperature and the second temperature, for example, the difference between the second temperature and the first temperature is a predetermined threshold value of the losing temperature, that is, t2=t1- Δt, T1 is used to represent the first temperature, T2 is used to represent the second temperature, Δt is used to represent the threshold value of the losing temperature, and t2=67 ℃ if t1=70 ℃, Δt=3 ℃.

It can be seen that implementing this alternative embodiment also enables to determine that the real-time temperature of the hot water satisfies the sterilization conditions only if the hot water in the heating branch is heated to the desired temperature and the temperature drop is small over a period of time, so that the sterilization effect of the waterway system is further improved due to the fact that the real-time temperature and the high-temperature holding time of the hot water for sterilization satisfy the sterilization requirements.

In this alternative embodiment, optionally, the control method may further include:

when the real-time temperature of the hot water is detected to be smaller than the second temperature in the preset time period, the operation of controlling the heating device corresponding to the heating branch to heat the water in the heating branch is re-executed, the heated hot water is obtained, whether the real-time temperature of the hot water is larger than or equal to a first temperature which is determined in advance is detected based on temperature detection equipment corresponding to the heating branch, and whether the real-time temperature of the hot water is larger than or equal to a second temperature which is determined in advance is detected based on temperature detection equipment in the preset time period after the heating device stops heating the water in the heating branch.

Namely, when the water temperature T in the heating branch reaches T1, heating is stopped, at the moment, the time T2 is started, when the water temperature T is detected to be less than T2 and is less than T1, the heating device is started again, the heating device is heated circularly until the water temperature T reaches T1, namely, heating is stopped, and the time T2 is restarted; when t2=t1, the water temperature T is more than or equal to T2, and the water pump is started to perform sterilization treatment of the waterway system.

The first temperature and/or the second temperature are determined according to instruction information in the high-temperature sterilization instruction, and the instruction information may include one or more of a target flushing duration, a target flushing temperature, a preset flushing branch and a target killing strain corresponding to the high-temperature sterilization mode.

For example, common species in waterways include shigella, streptococcus, escherichia coli, staphylococcus aureus, salmonella. In general, the sterilizing effect of the hot water at 65 ℃ on shigella and streptococcus is also sufficient, so that the second temperature matched with the shigella and streptococcus can be set to 65 ℃, and the first temperature can be set to 70 ℃ in consideration of temperature loss; the sterilizing effect of hot water at 65 ℃ on escherichia coli, staphylococcus aureus and salmonella is poor, and the sterilizing effect can be achieved only by 30 minutes, so that the second temperature matched with the escherichia coli, the staphylococcus aureus and the salmonella can be set to be 75 ℃, and the first temperature can be set to be 80 ℃ in consideration of temperature loss.

Therefore, the temperature required by high-temperature sterilization can be flexibly adjusted according to the requirements of users.

when the temperature of the tail end water is detected to be greater than or equal to the third temperature, the temperature control valve is controlled to be closed, so that when a user opens the water outlet device of the water consumption point, the temperature control valve intercepts the hot water on the corresponding water consumption branch to output the corresponding water consumption outlet, the water consumption branch can comprise a hot water consumption branch and/or a cold water consumption branch, and the water consumption point water outlet can comprise a hot water outlet and/or a cold water outlet.

Therefore, by arranging the temperature control valves at the cold water outlet and the hot water outlet, when the high-temperature sterilization is performed, if the water temperature is higher, the temperature control valve is closed, so that the condition that a user is scalded due to higher high-temperature hot water for the high-temperature sterilization is reduced.

In this alternative embodiment, as an alternative implementation manner, the control method may further include:

when the water temperature at the tail end is detected to be smaller than the third temperature, detecting whether a user opens a water outlet device with a water point;

and controlling the heating device to stop heating water in the heating branch circuit, or controlling the water pump to stop running so as to stop driving the hot water in the heating branch circuit to be output to the branch circuit to be cleaned through the water outlet of the heating branch circuit.

It can be seen that implementing this alternative embodiment can stop the high temperature sterilization process if the user needs water when performing high temperature sterilization and the water temperature is low, thereby being beneficial to preferentially satisfying the user's water demand.

In yet another alternative embodiment, after receiving the high temperature sterilization command, before controlling the corresponding heating device of the heating branch to heat the water in the heating branch to obtain the heated hot water, the control method may further include:

detecting whether the waterway system meets the heating starting condition of the heating device;

When the heating device is detected to meet the heating starting condition, triggering and executing the operation of controlling the heating device to continuously heat the water in the heating branch, so as to obtain heated hot water;

optionally, detecting whether the waterway system meets a heating start condition of the heating device includes;

detecting whether the heating device is in a standby state, and determining that the waterway system meets the heating starting condition of the heating device when the heating device is detected to be in the standby state; and/or the number of the groups of groups,

detecting whether the water quantity in the heating branch is larger than or equal to the preset water quantity, and determining that the waterway system meets the heating starting condition of the heating device when the water quantity in the heating branch is larger than or equal to the preset water quantity; and/or the number of the groups of groups,

detecting whether the heating raw material supply amount of the heating device is larger than or equal to a preset supply amount, and determining that the waterway system meets the heating starting condition of the heating device when the heating raw material supply amount is larger than or equal to the preset supply amount, wherein if the heating device is a gas water heater, the heating raw material is natural gas;

and, the control method may further include: when the heating device is detected not to be in the standby state, the heating device is controlled to be in the standby state.
