Referring to fig. 2, a method for controlling a water heater includes:
s201, under the condition that the user is determined to enter the motion state, the current indoor environment temperature of the environment where the water heater is located and the current body temperature of the user are obtained.
The user entering the motion state may be determined by: obtaining the current respiratory frequency of a user, and if the current respiratory frequency is greater than or equal to a set frequency threshold, determining that the user enters a motion state; or obtaining the current heart rate of the user, and if the current heart rate is greater than or equal to a set heart rate threshold value, determining that the user enters a motion state; or obtaining the current body temperature of the user, and determining that the user enters the motion state if the current body temperature of the user is greater than or equal to the set body temperature threshold.
S202, determining a set comfortable temperature corresponding to the current indoor environment temperature and the current user body temperature according to the corresponding relation of the environment temperature, the user body temperature and the comfortable temperature.
For example, the corresponding relationship between the ambient temperature, the user body temperature, and the comfort temperature is stored in the database in advance, and after the current indoor ambient temperature and the current user body temperature are obtained, the database may be queried to obtain the set comfort temperature corresponding to the current indoor ambient temperature and the current user body temperature.
Usually, the comfortable bathing temperature is 35-40 deg.C, and the comfortable temperature can be 35 deg.C, 36 deg.C, 37 deg.C, 38 deg.C, 39 deg.C or 40 deg.C. The lower the indoor ambient temperature is, the higher the set comfortable temperature is; the higher the indoor ambient temperature is, the lower the comfort temperature is set.
The higher the body temperature of a user during bathing, the less sensitive the user to high temperature and the more sensitive to low temperature, so that the higher the body temperature of the current user is, the higher the set comfortable temperature is, and the comfort level of the user is improved; the lower the body temperature of the user during bathing, the more sensitive the user is to high temperature and the less sensitive to low temperature, so that the lower the body temperature of the user is, the lower the set comfortable temperature is, and the comfort of the user is improved.
S203, obtaining the movement duration corresponding to the movement habit of the user, and controlling the water heater according to the movement duration and the set comfortable temperature to enable the water temperature of the water heater to reach the set comfortable temperature at the finishing moment corresponding to the movement duration.
After the user forms a stable exercise habit, the exercise duration is usually stable, for example, the exercise duration may be 45min, 60min, 90min or 120 min. The starting time of the movement time length is the time for determining that the user enters the movement state.
In order to enable the water temperature of the water heater to reach the set comfortable temperature at the end time corresponding to the movement time length, the longer the movement time length is, the lower heating power can be set for the water heater; the shorter the movement duration, the higher the heating power can be set for the water heater.
After the user starts to move, the proper set comfortable temperature is determined, after the user forms a stable movement habit, the movement time of the user is usually fixed, in the process of controlling the water heater to heat, the water temperature of the water heater reaches the set comfortable temperature at the end time corresponding to the movement time, on the basis that the user can use hot water with the comfortable temperature, the heat preservation time of the water heater can be reduced, and the energy consumed by the water heater is reduced.
In some embodiments, controlling the water heater according to the movement duration and the set comfort temperature may include: starting the water heater after the time length between the current time and the time when the user enters the motion mode is greater than or equal to the preset waiting time length, and controlling the water heater according to the set comfortable temperature; wherein the preset waiting time is less than or equal to the movement time. Namely, timing is started at the moment when the user enters the motion state, and after the recorded time length reaches the preset waiting time length, the water heater is started to start heating, so that the water temperature of the water heater reaches the set comfortable temperature.
Starting the water heater herein refers to starting cooling or heating the water heater to adjust the temperature of water in the water heater. Before the water heater is started, the water heater can be in a standby state and also can be in a shutdown state.
Therefore, the water heater is not required to be in a heating state in real time, the heating duration of the water heater is favorably reduced, and the service life of the water heater is prolonged.
Starting the water heater to start heating after the preset waiting time, wherein the water temperature of the water heater needs to reach the set comfortable temperature at the finishing moment corresponding to the movement time, and the preset waiting time cannot be too long, otherwise, the heating time is too short, and the water temperature of the water heater cannot reach the set comfortable temperature; the preset waiting time cannot be too short, otherwise, the water heater enters a heat preservation mode after the water temperature is heated to the set comfortable temperature, and the energy consumption of the water heater is improved. For this purpose, the determination of the preset waiting time period may include: obtaining a first temperature difference value between the current hot water temperature of the water heater and the set comfortable temperature; obtaining the heating time length corresponding to the average heating power of the water heater by the first temperature difference value; and determining the time length difference between the movement time length and the heating time length as a preset waiting time length.
Therefore, the proper preset waiting time can be determined, and the water temperature of the water heater reaches the set comfortable temperature at the finishing moment corresponding to the movement time.
In addition, in the process of determining the preset waiting time, the average heating power (rather than the maximum heating power or the minimum heating power) of the water heater is utilized, so that the heating power of the water heater can be further increased or reduced, and even if the environment changes or the set comfortable temperature changes, the water heater can timely heat the water temperature to the set comfortable temperature.
In practical application, the water heater can be an electric heating type water heater and also can be a heat pump type water heater. In the case that the water heater is a heat pump type water heater, after obtaining a heating time period in which the first temperature difference value corresponds to an average heating power of the water heater, the method may further include: obtaining a second temperature difference value between the current hot water temperature of the water heater and the current outdoor environment temperature of the environment where the water heater is located, and prolonging the heating time under the condition that the second temperature difference value is larger than a preset temperature threshold value; under the condition that the second temperature difference value is smaller than the preset temperature threshold value, the heating time length is shortened; and keeping the heating time period under the condition that the second temperature threshold value is equal to the preset temperature threshold value. Under the condition of prolonging the heating time, determining a preset waiting time according to the prolonged heating time and the motion time; in the case of shortening the heating time period, the preset waiting time period is determined with the shortened heating time period and the movement time period. Therefore, the more accurate preset waiting time can be obtained, so that the time when the water temperature of the water heater reaches the set comfortable temperature is closer to the end time corresponding to the movement time.
In practical application, the exercise intensity of the user in the exercise process changes, and then the body temperature of the user also changes, and under the condition, the set comfortable temperature of the water heater is determined according to the body temperature of the user at the moment when the user enters the exercise state, so that the set comfortable temperature is not accurate enough.
Therefore, the body temperature of the user can be detected in real time, the new set comfortable temperature can be determined according to the current body temperature of the user obtained in real time, and the water heater can be controlled according to the new set comfortable temperature.
If the set comfortable temperature changes before the water heater is started, re-determining a new set comfortable temperature and a preset waiting time; if the set comfortable temperature changes after starting, obtaining the residual time length between the current time and the ending time corresponding to the movement time length, obtaining the current water temperature of the water heater and the first temperature difference value of the set comfortable temperature, determining the expected heating power of the water heater corresponding to the first temperature difference value and the residual time length, and controlling the water heater according to the expected heating power.
Therefore, the set comfortable temperature of the water heater can be adjusted in real time, and even if a user does exercises with different intensities, the user can enjoy good bathing experience after the exercise is finished.
In addition, in the process of determining the preset waiting time for the first time, the average heating power of the water heater is adopted, so that after the water heater is started to heat and the set comfortable temperature is increased, the heating power of the water heater can be further increased on the basis of the average heating power to reach the expected heating power, and the water heater cannot be damaged.
Optionally, controlling the water heater according to the movement duration and the set comfortable temperature comprises: after the water heater is started, obtaining the current respiratory frequency of a user, and obtaining a first elevated temperature corresponding to the frequency difference value between the current respiratory frequency and the reference respiratory frequency under the condition that the current respiratory frequency is greater than the reference respiratory frequency corresponding to the body temperature of the current user; determining the sum of the set comfort temperature and the first elevated temperature as the compensated set comfort temperature; and controlling the water heater according to the compensated set comfortable temperature.
Or, the controlling the water heater according to the movement duration and the set comfortable temperature can include: after the water heater is started, obtaining the current heart rate of a user, and obtaining a second raised temperature corresponding to the heart rate difference value between the current heart rate and the reference heart rate under the condition that the current heart rate is larger than the reference heart rate corresponding to the body temperature of the user; and determining the sum of the set comfortable temperature and the second improved temperature as the compensated set comfortable temperature, and controlling the water heater according to the compensated set comfortable temperature.
For a user, the respiratory rate and the heart rate correspond to the body temperature of the user, for example, the heart rate increases 10 to 20 times every time the body temperature increases one degree. In embodiments of the present disclosure, each time the body temperature is raised by one degree, the corresponding heart rate is raised 10, 15 or 20 times.
In the above technical solution, the corresponding relationship between the current user body temperature and the reference respiratory frequency may be pre-stored in a database, and after the current user body temperature is obtained, the reference respiratory frequency corresponding to the current user body temperature may be obtained, and similarly, the corresponding relationship between the frequency difference between the current respiratory frequency and the reference respiratory frequency and the first elevated temperature may also be pre-stored in the database, and after the frequency difference between the current respiratory frequency and the reference respiratory frequency is obtained, the first elevated temperature corresponding to the frequency difference may be obtained through the database.
The corresponding relation between the current body temperature of the user and the reference heart rate can be prestored in a database, after the current body temperature of the user is obtained, the reference heart rate corresponding to the current body temperature of the user can be obtained, similarly, the corresponding relation between the heart rate difference value between the current heart rate and the reference heart rate and the second raised temperature is obtained, for example, the heart rate difference value is 10 times, 15 times or 20 times, the second raised temperature is 1 ℃, and the second raised temperature corresponding to the heart rate difference value can also be prestored in the database, after the heart rate difference value between the current heart rate and the reference heart rate is obtained, namely, the second raised temperature corresponding to the heart rate difference value can be obtained through the database.
After the user begins to perform high intensity exercise, the heart rate or respiratory rate first increases and after one or more minutes the user's body temperature begins to rise.
By adopting the technical scheme, the comfortable temperature can be compensated and set in advance, particularly, the user can compensate and set the comfortable temperature in advance at the moment of finishing the movement, so that the time for adjusting the water temperature for one minute or more can be obtained for the water heater, the water temperature can be adjusted to the set comfortable temperature at the moment of finishing the movement of the user, and the phenomenon that the water temperature in the water heater is too low is reduced.
Further, after the first elevated temperature or the second elevated temperature is adopted to compensate the set comfortable temperature, the water heater is controlled according to the movement duration and the set comfortable temperature, and the method further comprises the following steps: under the condition that the set comfortable temperature is increased, obtaining the remaining time length between the current time and the ending time corresponding to the movement time length; obtaining a third temperature difference value of the current water temperature of the water heater and the compensated set comfortable temperature; determining the expected heating power of the water heater corresponding to the third temperature difference and the remaining time; the water heater is controlled according to the expected heating power. Adopt above-mentioned technical scheme can adjust the comfortable temperature of setting for of water heater in advance, even the user carries out the motion of different intensity, after the motion, also can enjoy good bathing experience.
And when the user is determined to exit the motion state, or the water temperature in the water heater reaches the set comfortable temperature, the water heater enters a standby mode, or the water heater enters a heat preservation mode.
