and S101, acquiring the total preheating time required by the hot water treatment device.
The total preheating time required by the hot water treatment device can be set by a user, and can also be automatically obtained by the hot water treatment device according to the condition of the hot water treatment device during the first operation preheating or the historical preheating, wherein the historical preheating can be the last preheating or multiple preheating within a period of time.

S102, identifying that the hot water treatment device starts a preheating mode.
It should be noted that, an interactive interface or a working mode selection key of a user may be provided on the hot water treatment device, and the user may control the hot water treatment device to start the preheating mode through the interactive interface or the working mode selection key of the user.
Optionally, the selection operation of the user on the hot water treatment device is obtained by detecting a user interaction interface or a working mode selection key, and whether the user controls the hot water treatment device to start the preheating mode is identified according to the position of the selection operation.
S103, acquiring a first water inlet temperature and a first water outlet temperature in the hot water treatment device.
The water inlet interface and the water outlet interface of the hot water treatment device are respectively provided with a water inlet temperature sensor and a water outlet temperature sensor. Therefore, the first inlet water temperature of the hot water treatment device can be detected by the inlet water temperature sensor for a preset time, and the first outlet water temperature of the hot water treatment device can be detected by the outlet water temperature sensor for a preset time.
And S104, preheating control is carried out on the hot water treatment device according to the first water inlet temperature, the first water outlet temperature and the total preheating time.
And determining the first water inlet temperature, the first water outlet temperature and the total preheating time, and preheating the hot water treatment device according to the first water inlet temperature, the first water outlet temperature and the total preheating time.
As a possible implementation, the warm-up control of the hot water treatment apparatus may be performed by the following steps. As shown in fig. 5, this step includes:
s201, identifying whether the current preheating time of the hot water treatment device is less than the total preheating time.
When the hot water treatment device starts to warm up, the current warm-up time of the hot water treatment device can be recorded by the timer. If the current preheating time is greater than or equal to the total preheating time, executing step S302; if the current preheating time is less than the total preheating time, step S303 is performed.
And S302, controlling the hot water treatment device to stop the preheating mode.
And when the current preheating time is greater than or equal to the total preheating time, controlling the hot water treatment device to stop the preheating mode, namely finishing preheating.
And S303, controlling the start and stop of a gas valve and a water pump in the hot water treatment device according to the first water inlet temperature and the first water outlet temperature so as to circularly heat the hot water treatment device.
When the current preheating time is less than the total preheating time, the gas valve and the water pump in the hot water treatment device are controlled to be started and stopped according to the first water inlet temperature and the first water outlet temperature, so that the hot water treatment device can perform circular heating.
Alternatively, the gas valve and the water pump in the hot water treatment device may be start-stop controlled by the following steps. As shown in fig. 6, this step includes:
s301, identifying that the gas valve and the water pump are all opened.
When the hot water treatment device enters a preheating mode, a gas valve in the hot water treatment device is opened so that the hot water treatment device can be ignited and heated; at the same time, the water pump in the hot water treatment device is also started to promote the water in the user pipeline to be circularly heated.
S302, identifying that the duration that the first inlet water temperature is greater than or equal to the first temperature threshold value reaches a first preset duration, and/or the duration that the first outlet water temperature is greater than or equal to the second temperature threshold value reaches a first preset duration, and controlling the gas valve to be closed.
When the hot water treatment device starts to warm up, the first inlet water temperature and the first outlet water temperature will increase with the increase of the warm-up time. And when the first water inlet temperature is greater than or equal to a preset first temperature threshold value and/or the first water outlet temperature is greater than or equal to a preset second temperature threshold value, timing is started, and the duration is recorded. If the duration reaches the first preset duration, the fact that the water temperature of hot water in each area in the user pipeline reaches the set temperature is indicated, the gas valve is controlled to be closed, meanwhile, the water pump is kept in an open state, water circulation in the pipeline is promoted, and the phenomenon that the water temperature is uneven in the user pipeline is avoided. In order to avoid the situation that the water temperature in the middle part of the user pipeline does not reach the set temperature, in this embodiment, the first temperature threshold is set to be greater than the second temperature threshold, so that when the hot water flowing out of the water outlet port of the hot water treatment device flows through the user pipeline, the water temperature in the user pipeline can still reach the set temperature under the influence of the heat loss of the user pipeline. It should be understood that the second temperature threshold is greater than or equal to the set temperature of the hot water treatment device. Optionally, the first temperature threshold is the set temperature of the hot water treatment device +4 ℃; the second temperature threshold is the set temperature of the hot water treatment device.
Furthermore, if the gas valve is controlled to close upon the first inlet water temperature and/or the first outlet water temperature reaching the respective preset temperature threshold, it is likely that the actual water temperature in the pipeline remote from the hot water treatment device will be lower than the preset temperature threshold. Therefore, in this embodiment, when the first inlet water temperature and/or the first outlet water temperature just reach the respective preset temperature threshold, the gas valve is continuously controlled to be opened for a period of time, so as to ensure that the water temperature in the user pipeline is uniform. Namely, the gas valve is controlled to be closed when the duration of the first inlet water temperature and/or the first outlet water temperature reaches the first preset duration just after the first inlet water temperature and/or the first outlet water temperature reach the respective preset temperature threshold.
It should be understood that when the first inlet water temperature is identified to be less than the first temperature threshold value and the first outlet water temperature is identified to be less than the second temperature threshold value, the gas valve and the water pump are controlled to be continuously opened so as to circularly heat the water in the user pipeline.
S303, identifying that the duration of the first inlet water temperature which is greater than or equal to the first temperature threshold value reaches a second preset duration, and/or the duration of the first outlet water temperature which is greater than or equal to the second temperature threshold value reaches the second preset duration, and controlling the water pump to be closed.
After the gas valve is controlled to be closed, the duration that the first water inlet temperature is greater than or equal to a preset first temperature threshold value and/or the first water outlet temperature is greater than or equal to a preset second temperature threshold value is continuously recorded. And if the duration reaches the second preset duration, the water pump is controlled to be turned off, which indicates that the water in the user pipeline is circulated for multiple times under the action of the water pump, and the water temperature in the user pipeline reaches a uniform state after the multiple times of circulation.
And S304, recognizing that the closing time of the water pump reaches the preset closing time of the water pump, and controlling to start the water pump.
When the water pump is controlled to be closed, timing is started, and the closing time of the water pump is recorded. In the process of closing the water pump, hot water in the user pipeline exchanges heat with the outside; because the different areas of the user pipeline are in different environments, the heat exchange rate of the hot water in the different areas of the pipeline with the outside is different. Along with the gradual extension of the time of the water pump closing, the water temperature in the pipeline of a part of the user pipeline is lower than the set water temperature; that is to say, when the time that the water pump was closed reached preset water pump closing time, the condition that the temperature was less than the settlement temperature then begins to appear in the middle part region of user's pipeline, then at this moment, control was opened the water pump, made the water in the user's pipeline circulate to make the hydrothermal temperature in each region in the user's pipeline reach the homogeneous state, thereby made the user can not appear the condition of neglecting cold and neglecting hot when using hot water.
S305, identifying that the duration that the first inlet water temperature is smaller than the third temperature threshold value reaches a third preset duration, and/or the duration that the first outlet water temperature is smaller than the fourth temperature threshold value reaches the third preset duration, and controlling the gas valve to be opened.
After the gas valve in the hot water treatment device is closed, the temperature of the water in the user line will slowly decrease as time passes and as the water in the user line circulates. And when the first water inlet temperature is lower than a preset third temperature threshold value and/or the first water outlet temperature is lower than a preset fourth temperature threshold value, timing is started, and the duration is recorded. If the duration reaches a third preset duration, which indicates that the water temperature in the user pipeline is lower than the expected water temperature of the user, the gas valve is controlled to be opened to circularly heat the water in the user pipeline, so that the water temperature fluctuation in the user pipeline is ensured to be small. Wherein the third temperature threshold is greater than or equal to the fourth temperature threshold. It should be understood that the user's desired water temperature is below the set temperature of the hot water treatment device. Optionally, the third temperature threshold is-2 ℃ of the set temperature of the hot water treatment device; the fourth temperature threshold is the set temperature of the hot water treatment device of-2 ℃.
In summary, according to the control method of the hot water treatment device provided in the embodiment of the present invention, when the hot water treatment device starts the preheating mode, the preheating control is performed on the hot water treatment device according to the first water inlet temperature, the first water outlet temperature, and the total preheating time of the hot water treatment device, so that the set water temperature of the hot water treatment device can be adapted to the first water inlet temperature and the first water outlet temperature within the total preheating time, thereby reducing the fluctuation of the water temperature of the hot water preheated by the hot water treatment device, and improving the user experience.
In some embodiments, the total warm-up time required by the hot water treatment device is mainly obtained automatically by the hot water treatment device according to the situation when the hot water treatment device is first operated for warm-up or last warm-up, as shown in detail in fig. 7, and the steps include:
s401, detecting a second water inlet temperature and a second water outlet temperature in the first running preheating or last preheating process of the hot water treatment device.
In the process of preheating or last preheating during the first running of the hot water treatment device, the second water inlet temperature of the hot water treatment device can be detected through the water inlet temperature sensor at the water inlet interface of the hot water treatment device continuously or at preset intervals, and the second water outlet temperature of the hot water treatment device can be detected through the water outlet temperature sensor at the water outlet interface of the hot water treatment device continuously or at preset intervals.
S402, acquiring a first duration that the second inlet water temperature is greater than or equal to a preset first inlet water temperature threshold and/or the second outlet water temperature is greater than or equal to a preset first outlet water temperature threshold.
When the hot water treatment device starts to warm up, the second inlet water temperature and the second outlet water temperature will increase with the increase of the warm-up time. And when the second water inlet temperature is greater than or equal to the preset first water inlet temperature threshold and/or the second water outlet temperature is greater than or equal to the preset first water outlet temperature threshold, timing is started to obtain the first duration. In order to avoid the situation that the water temperature in the middle part of the user pipeline does not reach the set temperature, in this embodiment, the first inlet water temperature threshold is set to be greater than the first outlet water temperature threshold, so that when the hot water flowing out from the outlet port of the hot water treatment device flows through the user pipeline, the water temperature in the user pipeline can still reach the set temperature under the influence of the heat loss of the user pipeline. It should be understood that the first outlet water temperature threshold is greater than or equal to the set temperature of the hot water treatment device.
And S403, recognizing that the first duration reaches a fourth preset duration, and acquiring the running time of a water pump in the hot water treatment device from the starting time to the current time.
And when the first duration is recognized to reach the fourth preset duration, acquiring the running time of a water pump in the hot water treatment device from the starting time to the current time.
It should be understood that when the water pump is started, the timer may be used to start recording the length of time that the water pump is operating.
And S404, acquiring the total preheating time according to the running time of the water pump.
Alternatively, the total warm-up time may be calculated according to the following formula:
T＝T1/2+T0
wherein T is the total preheating time, T1For the running time of the water pump, T0To compensate for the time.
In some embodiments, the total warm-up time may be adjusted by a temperature adjustment key on the hot water treatment device, as described in more detail below. As shown in fig. 8, this step includes:
s501, acquiring a temperature adjusting instruction input by a user.
The user can issue the temperature adjusting instruction to the hot water treatment device through a user interaction interface on the hot water treatment device or a remote control device (such as a remote controller matched with the hot water treatment device), so that the hot water treatment device can acquire the temperature adjusting instruction input by the user.
And S502, adjusting the total preheating time according to the temperature adjusting instruction.
The hot water treatment device receives the temperature adjusting instruction, and then can adjust the total preheating time according to the temperature adjusting instruction.
Optionally, when the temperature adjustment instruction is received, the time for the user to input the temperature adjustment instruction is identified, and when the time for the temperature adjustment instruction input by the user reaches a preset time, the total preheating time is adjusted.

Meanwhile, the hot water treatment device will respond to the operation of the user to the operation component corresponding to the preheating mode.
And S602, controlling the hot water treatment device to switch to the target working mode according to the operation information of the operation assembly and the working mode of the hot water treatment device before the operation.
When the user operates the operation assembly, the operation information of the current operation of the user on the operation assembly is obtained. And when the operation information reaches the preset operation information, switching the previous working mode of the hot water treatment device to the target working mode. The operation information may be an operation area, an operation posture, an operation stay time, and the like; different operational information may correspond to, but is not limited to, different operating modes.
For example, when the operation information is an operation region, different operation regions may correspond to different operation modes. And controlling the hot water treatment device to switch from the current working mode to the comfort mode if the area operated by the user is the comfort mode.
When the operation information is the stay time of the operation and the front hot water treatment device is in the preheating mode, if the user wants to switch to the comfort mode, the user can press a 'zero cold water' key on the hot water treatment device for a long time, and when the key duration reaches 5s, the hot water treatment device is controlled to switch from the preheating mode to the comfort mode.
