It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

FIG. 1 is a schematic flow diagram of a method for effluent control according to some embodiments of the present invention. As shown in FIG. 1, the effluent control method of the embodiment includes steps S11-S13.

In step S11, the ambient temperature, the human body temperature of the user, the water inlet pressure, and the water inlet temperature are acquired.

In some embodiments, the ambient temperature may be a current local ambient temperature, such as may be obtained over a network or detected indoors or outdoors; the human body temperature of the user can be historical body temperature data and current body temperature data of the user, or only the current body temperature data, and the data can be shared by the user and can also be obtained according to real-time detection; the water inlet pressure can be obtained according to actual detection or can be obtained directly or through calculation according to the local current water pressure condition; the inlet water temperature can be obtained according to actual detection, or can be obtained directly or through calculation according to the local current weather condition or water temperature condition.

In step S12, based on the water outlet control mode, water outlet control information is generated according to the ambient temperature, the human body temperature, the water inlet pressure and the water inlet temperature, wherein the water outlet control information includes a first output water temperature, a second output water temperature, a first output water amount and a second output water amount.

In some embodiments, since the ambient temperature reflects the current weather conditions, such as the seasonal cold and warm conditions, a comfortable target outlet water temperature suitable for the seasonal cold and warm can be obtained according to the ambient temperature; the data of the human body temperature also show a certain rule, and the target outlet water temperature with certain comfort can be obtained according to the human body temperature. Meanwhile, the target outlet water temperature is obtained according to the environment temperature and the human body temperature, and a comfortable outlet water temperature change range (such as a first outlet water temperature as an upper temperature limit and a second outlet water temperature as a lower temperature limit) can be obtained. Based on the water outlet control mode, the first output water volume and the second output water volume with different sizes can be generated according to the local water temperature, the water pressure condition and the variation range of the water outlet temperature. For example, the water outlet control modes may include a high temperature and high water mode (i.e., the output water temperature is at a peak value and the output water amount is at a peak value, and the output water temperature is at a valley value and the output water amount is at a valley value), a high temperature and low water mode (i.e., the output water temperature is at a peak value and the output water amount is at a valley value and the output water amount is at a peak value), and the like. In addition, the water outlet control mode can be selected by a user or obtained by the system according to other modes, such as intelligent matching and the like.

In step S13, the water heater is controlled to discharge water in a water temperature change and water volume change manner by using the first output water temperature and the second output water temperature as a water temperature change section and using the first output water volume and the second output water volume as a water volume change section according to the water discharge control mode.

In some embodiments, it can be understood that, according to the water outlet control mode, the water heater is controlled to adjust the gas proportional valve, the blower, the water pump, the flow regulating valve and the like in real time to cooperatively work to realize the output of the change of the water temperature and the water amount (for example, when the first output water temperature is greater than the second output water temperature, the first output water temperature is high, the second output water temperature is low, and the high-low temperature alternating change or the temperature gradient control is performed), the first output water amount and the second output water amount are water amount change regions (for example, when the first output water amount is greater than the second output water amount, the first output water amount is large, the second output water amount is small, and the large-small water alternating change or the water amount gradient control is performed); or the water heater is controlled to adjust the electric heating component and the water flow adjusting component so as to realize the output of the water temperature and the water quantity which are changed alternately. For example, the mode of the simultaneous magnitude alternation of the effluent temperature and the effluent amount and the running time can make different effluent control modes according to the actual needs of the bather, such as sub-mode 1: the high-temperature water and the low-temperature water are changed alternately in a periodic way at the same running time; or, sub-mode 2: the running time of the high-temperature large water is longer than that of the low-temperature small water and changes periodically; or, sub-mode 3: the running time of the high-temperature large water is shorter than that of the low-temperature small water so as to periodically and alternately change; or, sub-mode 4: the high-temperature big water and the low-temperature small water are periodically and alternately transformed by sine waves or cosine waves; or, sub-mode 5: after the high-temperature big water or the low-temperature small water runs for a period of time, the high-temperature big water or the low-temperature small water runs for a period of time again with the low-temperature small water or the high-temperature big water to periodically and alternately change after the high-temperature big water or the low-temperature big water runs for a period of time with the reference output water temperature (the reference output water temperature is a temperature in a water temperature change interval, such as a comfortable temperature for daily bathing) and the reference output; and so on.

The invention can automatically generate the water outlet temperature suitable for the user according to the environment temperature and the body temperature of the user, and controls the water heater to discharge water in the form of temperature change and water quantity change according to the water outlet temperature. Therefore, the multifunctional bathing experience of the user can be further improved on the premise of matching the weather condition and the body temperature condition of the user, for example, the functions of high and low temperature changes of the water outlet temperature and water in size can be used for realizing alternate massage stimulation on the body, and the multifunctional bathing device is beneficial to increasing the elasticity of blood vessels, improving the blood circulation, relieving fatigue, improving the blood circulation of the body and enhancing the metabolism.

Fig. 2 is a schematic flow chart of a water outlet control method according to other embodiments of the present invention. As shown in FIG. 2, the effluent control method of the embodiment includes steps S21-S27.

In step S21, the ambient temperature, the human body temperature of the user, the water inlet pressure, and the water inlet temperature are acquired.

Step S21 is the same as the corresponding steps in the above embodiments, and is not described here again.

In step S22, a first output water temperature and a second output water temperature are generated based on the ambient temperature and the human body temperature.

In some embodiments, since the ambient temperature reflects the current weather conditions, such as the seasonal cold and warm conditions, a comfortable outlet water temperature suitable for the seasonal cold and warm conditions can be obtained according to the ambient temperature; the data of the human body temperature also show a certain rule, and the water outlet temperature with certain comfort can be obtained according to the human body temperature. Therefore, the ideal outlet water temperature can be obtained according to the environment temperature and the human body temperature, for example, the ideal outlet water temperature change range can be obtained by taking the environment temperature as a reference judgment basis and the human body temperature as a correction value.

In step S23, a first water temperature time, a second water temperature time, a first water volume time, and a second water volume time are acquired.

In some embodiments, the first output water temperature is greater than the second output water temperature, and the first output water amount is greater than the second output water amount; the water outlet control mode includes water temperature change time information and water volume change time information, the water temperature change time information includes a first water temperature time corresponding to the first output water temperature and a second water temperature time corresponding to the second output water temperature, and the water volume change time information includes a first water volume time corresponding to the first output water volume and a second water volume time corresponding to the second output water volume.

In step S24, it is determined whether the first water temperature time and the first water amount time at least partially overlap.

In some embodiments, the first water temperature time is an operation time corresponding to a peak value of the water temperature change (first output water temperature), and the first water amount time is an operation time corresponding to a peak value of the water amount change (first output water amount), and when the first water temperature time and the first water amount time partially or completely coincide, the first output water temperature imposes a certain limit on the first output water amount under the same external and internal conditions. Thus, determining whether the first water temperature time and the first water volume time at least partially coincide may be used to select the manner of calculation of the output water volume.

In step S25, if yes, a first output water volume and a second output water volume are generated based on the first output water temperature, the inlet water pressure, and the inlet water temperature based on the heating load of the water heater.

In some embodiments, when the first water temperature time and the first water amount time at least partially coincide (e.g., high temperature and high water mode), it is necessary to generate the first output water amount and the second output water amount according to the first output water temperature, the water inlet pressure and the water inlet temperature based on the heating load of the water heater, or calculate the first output water amount and then obtain the second output water amount according to the first output water amount and the set difference.

If not, in step S26, a first output water volume and a second output water volume are generated based on the first output water temperature, the second output water temperature, the inlet water pressure, and the inlet water temperature based on the heating load of the water heater.

In some embodiments, when the first water temperature time does not coincide with the first water volume time, the first output water temperature, the second output water temperature, the water inlet pressure, and the water inlet temperature are taken into consideration in combination, and the first output water volume and the second output water volume are obtained based on the heating load.

In step S27, the water heater is controlled to discharge water in a water temperature change and water volume change manner by using the first output water temperature and the second output water temperature as a water temperature change section and using the first output water volume and the second output water volume as a water volume change section according to the water discharge control mode.

Step S27 is the same as the corresponding steps in the above embodiments, and is not described here again.

FIG. 3 is a schematic flow chart of water outlet control according to still other embodiments of the present invention, which specifically includes steps S31-S38:

in some embodiments, the outlet control information further includes a reference output water temperature and a reference output water amount, the reference output water temperature being less than the first output water temperature and greater than the second output water temperature, the reference output water amount being less than the first output water amount and greater than the second output water amount; the water temperature change time information further includes a reference water temperature time corresponding to the reference output water temperature, and the water amount change time information further includes a reference water amount time corresponding to the reference output water amount.

In step S31, the ambient temperature, the human body temperature of the user, the water inlet pressure, and the water inlet temperature are acquired.

Step S31 is the same as the corresponding steps in the above embodiments, and is not described here again.

In step S32, a reference output water temperature is generated based on the ambient temperature and the human body temperature.

In some embodiments, the step of generating a reference output water temperature based on the ambient temperature and the human body temperature comprises:

A. and determining a corresponding water temperature initial value according to the numerical range of the environment temperature, wherein the water temperature initial value is in negative correlation with the numerical value of the environment temperature.

In some embodiments, the corresponding initial value of water temperature may be determined according to the numerical range of the ambient temperature, for example, referring to table 1, the initial value of water temperature may be determined according to the corresponding relationship of table 1. For example, when the ambient temperature is in the range of 16 to 21, the initial value of the water amount may be 43.

Ambient temperature（℃）	Initial value of water temperature
		≤15	45
16 or more than or equal to 21 percent of ambient temperature	43
		The environmental temperature is more than or equal to 22 and less than or equal to 27	40
The ambient temperature is more than or equal to 28	38

TABLE 1

B. And determining a corresponding water temperature correction value according to the numerical range of the human body temperature, wherein the water temperature correction value is in negative correlation with the numerical value of the human body temperature.

In some embodiments, the corresponding water temperature correction value is determined according to the value range of the human body temperature, wherein the human body temperature may be the human body surface temperature, for example, referring to table 2, the water temperature correction value may be determined according to the corresponding relationship of table 2, for example, when the human body temperature is in the range of 36.5-37.5 ℃, the water temperature correction value is 0.

Body temperature (. degree. C.)	Correction value of water temperature
		35～36.5	+1.5
36.5～37.5	0
		>37.5	-1.5

TABLE 2

C. And generating a reference output water temperature according to the initial water temperature value and the water temperature correction value.

In some embodiments, the reference output water temperature is generated based on the initial water temperature value and the water temperature correction value, for example, the reference output water temperature is 43 ℃ when the initial water temperature value is 43 and the water temperature correction value is 0, and the sum of the initial water temperature value and the water temperature correction value is 43 ℃.

In step S33, a first output water temperature and a second output water temperature are generated based on the reference output water temperature;

in some embodiments, the first output water temperature is obtained from a reference output water temperature and a first corrected water temperature, and the first corrected water temperature may be obtained according to some practical situations, such as according to an ambient temperature, a human body temperature, and the like, or according to a normal range of the reference output water temperature combined with the human body. Wherein the step of generating the first output water temperature from the reference output water temperature and the first corrected temperature may include:

A. and determining a first correction water temperature according to the initial water temperature value, wherein the first correction water temperature is in negative correlation with the initial water temperature value. The initial value of the water temperature reflects the ambient temperature and is positively correlated with the reference output water temperature, and when the reference output water temperature is higher, the reference output water temperature is closer to the limit high temperature which can be born by the human body, and the increasable value, namely the first correction water temperature is smaller, so that the first correction water temperature can be determined according to the initial value of the water temperature and is negatively correlated with the first correction water temperature.

B. And calculating the sum of the reference output water temperature and the first corrected water temperature to obtain a first output water temperature. The first output water temperature may be an upper limit of the water temperature change, and is obtained by adding the reference output water temperature and the first corrected water temperature.

C. And generating a second output water temperature according to the reference output water temperature and a second correction temperature, wherein the value range of the second correction water temperature comprises 3-25 ℃. The second output water temperature is obtained from the reference output water temperature and a second correction temperature, and the second correction water temperature can be obtained according to some practical conditions, such as the environment temperature, the human body temperature and the like, and can also be obtained according to the height of the reference output water temperature and the normal range born by the human body.

Wherein the step of generating the second output water temperature according to the reference output water temperature and the second corrected temperature according to some embodiments of the present invention comprises:

A. and determining a second corrected water temperature according to the initial water temperature value, wherein the second corrected water temperature is positively correlated with the initial water temperature value. The initial value of the water temperature reflects the ambient temperature and is positively correlated with the reference output water temperature, and when the reference output water temperature is higher, the reference output water temperature is closer to the limit high temperature which can be born by the human body, and the value which can be reduced at the moment is larger, namely the second correction water temperature is larger, so that the second correction water temperature can be determined according to the initial value of the water temperature and is positively correlated with the initial value of the water temperature.

B. And calculating the difference between the reference output water temperature and the second corrected water temperature to obtain a second outlet water temperature. The second output water temperature may be a lower limit of the water temperature change, and is obtained by adding the reference output water temperature and the second corrected water temperature.

In step S34, the first water temperature time, the second water temperature time, the reference water temperature time, the first water volume time, the second water volume time, and the reference water volume time are acquired.

In step S35, it is determined whether the first water temperature time and the first water amount time at least partially overlap.

In some embodiments, when the first water temperature time at least partially coincides with the first water volume time, the first output water volume may be generated based on the first output water temperature, the inlet water pressure, and the inlet water temperature based on a heating load of the water heater, as described in the above embodiments.

If not, in step S36, a reference output water volume is generated based on the reference output water temperature, the inlet water pressure, and the inlet water temperature based on the heating load of the water heater.

In some embodiments, when the first water temperature time does not coincide with the first water volume time, the first output water volume may be generated based on the reference output water temperature, the inlet water pressure, and the inlet water temperature based on the heating load of the water heater to simplify calculation of the water volume. Specifically, the step of generating the reference output water amount according to the reference output water temperature, the inlet water pressure, and the inlet water temperature includes the following three steps of A, B, C.

A. And determining a corresponding water quantity initial value according to the numerical range of the water inlet pressure. Wherein, can confirm the corresponding water yield initial value according to the numerical range of pressure of intaking, for example, see table 3, can confirm the water yield initial value according to the corresponding relation of table 3. For example, when the water inlet pressure is in the range of 0.35-0.50 MPa, the initial value of the water quantity can be 9.5.

Pressure of water intake (MPa)	Initial value of water amount (L/min)
		0.05～0.15	7
0.15～0.35	8.5
		0.35～0.50	9.5
>0.50	10

Table 3.

B. And determining a corresponding water quantity correction value according to the difference range of the target water outlet temperature and the target water inlet temperature. Wherein, the corresponding water amount correction value is determined according to the difference range of the target outlet water temperature and the inlet water temperature, for example, referring to table 4, the water amount correction value can be determined according to the corresponding relation of table 4, for example, when the temperature difference is 15-20 ℃, the water amount correction value is 0.

Temperature difference (. degree.C.)	Correction value of water quantity
		0～15	+1
15～20	0
		20～27	-1
>27	-1.5

TABLE 4

C. And generating a reference output water quantity according to the initial water quantity value and the water quantity correction value. If the sum of the initial water quantity value and the water quantity correction value is 9.5 when the initial water quantity value is 9.5 and the water quantity correction value is 0, the reference output water quantity is the water quantity corresponding to 9.5L/min.

The specific steps of generating the second output water volume according to the reference output water volume and the second correction water volume comprise:

A. and determining a second correction water quantity according to the initial water quantity value. Wherein, since the initial value of the water amount reflects the pressure of the water inlet, for example, when the initial value of the water amount is smaller, the pressure value required for pressurization may be larger, or vice versa. Therefore, the corrected water amount for calculating the large and small water amounts can be obtained from the initial water amount value.

B. And calculating the difference between the reference output water quantity and the second corrected water quantity to obtain a second outlet water quantity. And if the second output water quantity is smaller than the first output water quantity, obtaining the second output water quantity according to the difference between the reference output water quantity and the second correction water quantity.
