Fig. 2 is a schematic diagram of a method for controlling a water heater provided by an embodiment of the present disclosure. The method for controlling the water heater may be executed by a controller in the water heater, or by a server in a smart home system, or by a control panel or other smart terminals (such as smart phones, tablet computers, etc.) matched with the water heater.

As shown in Fig. 2, the method for controlling the water heater includes:

S201. When it is determined that the user is in an exercise state, obtain the current indoor ambient temperature of the environment where the water heater is located and the current user's body temperature.

It can be determined that the user enters the exercise state by the following methods: obtain the user's current breathing rate, if the current breathing rate is greater than or equal to the set frequency threshold, then determine that the user enters the exercise state; or obtain the user's current heart rate, if the current heart rate is greater than or equal to If the heart rate threshold is set, it is determined that the user enters the exercise state; or, the user's current user body temperature is obtained, and if the current user body temperature is greater than or equal to the set body temperature threshold, it is determined that the user enters the exercise state.

S202. Determine a set comfortable temperature corresponding to the current indoor ambient temperature and the current user's body temperature according to the correspondence between the ambient temperature, the user's body temperature, and the comfortable temperature.

For example, the corresponding relationship between ambient temperature, user body temperature and comfortable temperature is stored in the database in advance. After obtaining the current indoor ambient temperature and current user body temperature, the database can be queried to obtain the corresponding set the comfort temperature.

Normally, the comfortable temperature for bathing is between 35°C and 40°C, and the set comfortable temperature can be 35°C, 36°C, 37°C, 38°C, 39°C or 40°C. The lower the indoor ambient temperature, the higher the set comfortable temperature; the higher the indoor ambient temperature, the lower the set comfortable temperature.

The higher the user's body temperature when bathing, the less sensitive the user is to high temperature and the more sensitive to low temperature, so that the higher the current user's body temperature, the higher the set comfortable temperature to improve the user's comfort; the lower the user's body temperature when bathing , the more sensitive the user is to high temperature and the less sensitive to low temperature, the lower the current user's body temperature is, the lower the set comfortable temperature is to improve the user's comfort.

S203. Obtain the exercise duration corresponding to the exercise habit of the user, and control the water heater according to the exercise duration and the set comfortable temperature, so that the water temperature of the water heater reaches the set comfortable temperature at the end time corresponding to the exercise duration.

After the user forms a stable exercise habit, the exercise duration is usually stable, for example, the exercise duration can be 45min, 60min, 90min or 120min. The start time of the exercise duration is the moment when the user is determined to enter the exercise state.

In order to make the water temperature of the water heater reach the set comfortable temperature at the end of the exercise duration, the longer the exercise duration, the lower the heating power can be set for the water heater; the shorter the exercise duration, the higher the heating power can be set for the water heater.

In some specific applications, controlling the water heater according to the exercise duration and the set comfortable temperature may include: starting the water heater after the time between the current moment and the moment when the user enters the exercise mode is greater than or equal to the preset waiting period, and according to A comfortable temperature is set to control the water heater; wherein, the preset waiting time is less than or equal to the exercise time. That is, start timing when it is determined that the user enters the exercise state, and when the recorded time reaches the preset waiting time, start the water heater to start heating, so that the water temperature of the water heater reaches the set comfortable temperature.

Starting the water heater here refers to starting the water heater to cool or heat, so as to adjust the water temperature in the water heater. Before the water heater starts, the water heater can be in the standby state, and can also be in the off state.

This does not need to make the water heater in a heating state in real time, which helps to reduce the heating time of the water heater and improve the service life of the water heater.

After the preset waiting time, start the water heater to start heating. It is necessary to make the water temperature of the water heater reach the set comfortable temperature at the end of the exercise time. The preset waiting time should not be too long, otherwise the heating time will be too short and the water temperature of the water heater will not reach Set a comfortable temperature; the preset waiting time should not be too short, otherwise the water heater will enter the heat preservation mode after heating the water to the set comfortable temperature, which will increase the energy consumption of the water heater. To this end, the determination of the preset waiting time may include: obtaining the first temperature difference between the current hot water temperature of the water heater and the set comfortable temperature; obtaining the heating time corresponding to the first temperature difference and the average heating power of the water heater; The time difference between the exercise time and the heating time is determined as the preset waiting time.

In this way, an appropriate preset waiting time can be determined, so that the water temperature of the water heater reaches the set comfortable temperature at the end time corresponding to the exercise time.

In addition, in the process of determining the preset waiting time, the average heating power of the water heater (not the maximum heating power or the minimum heating power) is used, so that the water heater can further increase the heating power or further reduce the heating power, even if the environment changes, or If the set comfortable temperature changes, the water heater can also heat the water to the set comfortable temperature in time.

In practical applications, the water heater may be an electric heating water heater or a heat pump water heater. In the case where the water heater is a heat pump water heater, after obtaining the first temperature difference and the heating duration corresponding to the average heating power of the water heater, it may further include: obtaining the current hot water temperature of the water heater and the current outdoor environment of the environment where the water heater is located The second temperature difference of the temperature, when the second temperature difference is greater than the preset temperature threshold, extend the heating time; when the second temperature difference is less than the preset temperature threshold, shorten the heating time; at the second temperature When the threshold is equal to the preset temperature threshold, keep heating for a long time. In the case of extending the heating time, the preset waiting time is determined by the extended heating time and exercise time; in the case of shortening the heating time, the preset waiting time is determined by the shortened heating time and exercise time. In this way, a relatively 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 exercise time.

In practical applications, if the user's exercise intensity changes during the exercise process, the user's body temperature will also change. In this case, it is not accurate enough to determine the set comfortable temperature of the water heater based on the user's body temperature when entering the exercise state.

Therefore, the user's body temperature can be detected in real time, and a new set comfortable temperature can be determined according to the current user's body temperature 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, then re-determine the new set comfortable temperature and the preset waiting time; Obtain the first temperature difference between the current water temperature of the water heater and the set comfortable temperature, determine the expected heating power of the water heater corresponding to the first temperature difference and the remaining time, and control the water heater according to the expected heating power.

In this way, the set comfortable temperature of the water heater can be adjusted in real time, and even if the user exercises with different intensities, he can enjoy a good bathing experience after the exercise.

In addition, in the process of determining the preset waiting time for the first time, the average heating power of the water heater can be used to ensure that after the water heater starts to heat and the set comfortable temperature increases, the water heater can be further improved on the basis of the average heating power. Increase the heating power to achieve the desired heating power without causing damage to the water heater.

Optionally, controlling the water heater according to the exercise duration and the set comfortable temperature includes: obtaining the user's current breathing rate after the water heater is started, and if the current breathing rate is greater than the reference breathing rate corresponding to the current user's body temperature, Obtain the first increased temperature corresponding to the frequency difference between the current respiratory rate and the reference respiratory rate; determine the sum of the set comfortable temperature and the first increased temperature as the compensated set comfortable temperature; according to the compensated set comfortable temperature The temperature is controlled on the water heater.

Alternatively, controlling the water heater according to the exercise duration and the set comfortable temperature may include: obtaining the user's current heart rate after the water heater is started, and obtaining the current heart rate and the reference heart rate when the current heart rate is greater than the reference heart rate corresponding to the current user's body temperature The second increased temperature corresponding to the heart rate difference of the heart rate; the sum of the set comfortable temperature and the second increased temperature is determined as the compensated set comfortable temperature, and the water heater is controlled according to the compensated set comfortable temperature.

For a user, there is a corresponding relationship between the respiratory rate and the user's body temperature, and there is also a corresponding relationship between the heart rate and the user's body temperature. For example, when the body temperature rises by one degree, the heart rate rises 10 to 20 times. In the embodiment of the present disclosure, every degree of body temperature increase corresponds to 10, 15 or 20 heart rate increases.

In the above technical solution, the correspondence between the current user's body temperature and the reference respiratory rate can be pre-stored in the database. After obtaining the current user's body temperature, the reference respiratory rate corresponding to the current user's body temperature can be obtained. Similarly, the current respiratory rate The corresponding relationship between the frequency difference value of the reference respiratory rate and the first increased temperature can also be pre-stored in the database. After obtaining the frequency difference value between the current respiratory frequency and the reference respiratory frequency, the frequency difference corresponding to the frequency difference can be obtained through the database. first increase the temperature.

The corresponding relationship between the current user's body temperature and the reference heart rate can be pre-stored in the database. After obtaining the current user's body temperature, the reference heart rate corresponding to the current user's body temperature can be obtained. Similarly, the heart rate difference between the current heart rate and the reference heart rate can be obtained. The corresponding relationship of the second increased temperature, for example, the heart rate difference is 10 times, 15 times or 20 times, and the second increased temperature is 1°C, which can also be pre-stored in the database. After obtaining the heart rate difference between the current heart rate and the reference heart rate, That is, the second increased temperature corresponding to the heart rate difference can be obtained through the database.

After the user starts high-intensity exercise, the heart rate or breathing rate first increases, and after one or more minutes, the user's body temperature begins to rise.

By adopting the above technical solution, the set comfortable temperature can be compensated in advance, especially when the user is about to finish exercising, the set comfortable temperature can be compensated in advance, which can make the water heater adjust the water temperature for one minute or more. At the end of the user's exercise, the water temperature is adjusted to the set comfortable temperature to reduce the phenomenon that the water temperature in the water heater is too low.

Further, after the set comfort temperature is compensated by using the first increase temperature or the second increase temperature, the water heater is controlled according to the exercise duration and the set comfort temperature, which also includes: when the set comfort temperature is increased, obtaining The remaining time between the current moment and the end time corresponding to the exercise duration; obtain the third temperature difference between the current water temperature of the water heater and the compensated set comfort temperature; determine the third temperature difference and the water heater’s expectation corresponding to the remaining time Heating power; controls the water heater according to the desired heating power. By adopting the above technical solution, the set comfortable temperature of the water heater can be adjusted in advance, and even if the user exercises with different intensities, he can enjoy a good bathing experience after the exercise is over.

When it is determined that the user quits the exercise state, or the water temperature in the water heater reaches the set comfortable temperature, the water heater enters the standby mode, or the water heater enters the heat preservation mode.
