Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to predict the set temperatures of the water heaters in different corresponding time periods in the future water using process according to the water consumption corresponding to different time periods in the historical water using process and the water consumption which can be supplied by the water heaters at different set temperatures. The invention can solve the problem of energy consumption waste caused by that a user always fixedly sets the temperature of the water heater at a higher gear for operation in the use process of the electric water heater. The working principle and working process of the automatic control method for the water heater provided by the present application will be explained in detail by the specific embodiments.

Fig. 1 shows a flowchart of an automatic control method for a water heater according to an embodiment of the present invention, and referring to fig. 1, the automatic control method for a water heater according to an embodiment of the present invention includes:

step 101: determining the water consumption corresponding to different time periods in the historical water consumption process;

step 102: determining the water consumption which can be supplied by the water heater at different set temperatures;

step 103: predicting the set water heater temperatures in different time periods corresponding to the future water use process according to the water use amounts corresponding to different time periods in the historical water use process and the water use amounts which can be supplied by different set water heater temperatures;

step 104: and controlling the water heater according to the predicted set temperatures of the water heater at different time periods in the future water using process.

In this embodiment, the different time periods may refer to different time periods in a day, such as 12:00-14:00, 14:00-16:00, and 16:00-18: 00. It may also refer to different time periods of the week, such as monday, tuesday, wednesday, etc. And also refers to a combination of the two, such as Monday 12:00-14:00, 14:00-16:00, 16:00-18:00, Tuesday 12:00-14:00, 14:00-16:00, 16:00-18:00, Wednesday 12:00-14:00, 14:00-16:00, 16:00-18:00, and the like. In this embodiment, the historical water usage process may refer to a historical one-day water usage process, or may refer to a historical multiple-day water usage process. For example, the set temperature of the water heater at different time periods in the future day can be predicted according to the water consumption at different time periods in the historical 7-day water using process. For another example, the set temperature of the water heater at different time periods from monday to sunday in the next week can be predicted according to the water consumption at different time periods from monday to sunday in the historical 7-day water consumption process.

In this embodiment, when the set temperatures corresponding to different time periods corresponding to the future water use process of the water heater are predicted according to the water consumption of different time periods in the historical water use process, the following method can be further adopted: the method comprises the steps of determining a typical day in historical water consumption days, such as a first day, assuming Monday, and having a relatively large reference value, then determining set temperatures corresponding to different time periods in the day according to water consumption corresponding to the different time periods in the day and water consumption capable of being supplied by the water heater at different set temperatures, and finally predicting the set temperatures corresponding to the different time periods in the future water consumption process of the water heater according to the set temperatures corresponding to the different time periods in the day.

In this embodiment, the set temperature of the water heater may be a discrete physical temperature adjustment level (e.g. 40 ℃, 45 ℃, 50 ℃) in the water heater, or a continuous set temperature that is controlled in real time by an electric control algorithm, e.g. 41 ℃, 41.5 ℃, 42 ℃, 43 ℃, 44 ℃, 45 ℃, etc.

In this embodiment, it should be noted that, before the step 101 is performed, a step of acquiring historical water consumption data is performed, where the historical water consumption data refers to data generated during the historical use of the water heater by the user, such as water consumption (determined according to water flow and water use time), temperature in the liner, and water inlet temperature. Specifically, when acquiring historical water consumption data, a water consumption event may be constructed based on state data reported by sensors (including a temperature sensor, a flow sensor, a timer, and the like) arranged inside the water heater, and then indexes of the water consumption event, such as (average) water flow, an (average) liner temperature, an (average) water inflow temperature, and water consumption duration, may be acquired. The water consumption of the water use events in different time periods can be calculated according to the information such as the average water flow, the time duration and the like of the water use events in different time periods. For example, when the water heater has history state reporting data for 14 consecutive days, every two adjacent states (one bar state data represents the state of the water heater at the reporting moment and includes information of the current water flow, the current temperature in the liner, the current time point and the like) constitute a water use event, wherein the temperature in the liner is data acquired by the middle temperature sensor.

In this embodiment, after obtaining historical water consumption data, can be according to the setting temperature of the corresponding different time quantum in the future water use in-process of water heater of the water consumption prediction of different time quantum in the historical use, when the setting temperature of the corresponding different time quantum in the future water use in-process of water heater is predicted according to the water consumption of different time quantum in the historical use, need according to the water consumption that the different time quantum corresponds in the historical water use in-process and the water consumption that the different setting temperature of water heater can supply, predict the water heater setting temperature of the corresponding different time quantum in the future water use. For example, the set temperatures corresponding to different time periods of each day in the historical water usage days can be determined according to the water consumption corresponding to different time periods of each day in the historical water usage days and the water consumption capable of being supplied by different set temperatures of the water heater, and then the set temperatures corresponding to different time periods of each day in the future water usage process of the water heater can be predicted according to the set temperatures corresponding to different time periods of each day in the historical water usage days.

For example, if the historical water consumption data includes historical water consumption days of 6 days, the water consumption corresponding to different time periods of each day in the 6 days is respectively obtained according to the historical water consumption data as follows:

18:00-20:00: 50 liters;

20:00-22:00: 50 liters;

22:00-24:00: 5 liters;

in this embodiment, the water usage in the different periods shown above may be the water usage in different temperature conditions. For example, the water consumption in the time period of 12:00-14:00 and in the time period of 20:00-22:00 can correspond to different water inlet temperatures and liner temperatures. In this embodiment, the difference between the temperature of the inlet water and the temperature inside the bladder is not taken into consideration, and the corresponding set temperatures in different time periods are predicted only according to the amount of water consumption. However, in other embodiments of the present invention, the water consumption under different temperature conditions is unified to the water consumption under the standard temperature, and for the technical solution of this part, reference may be made to the following description of other embodiments.

After obtaining the historical water consumption data, the next step is to determine the water consumption that can be supplied by the water heater at different set temperatures, for example, assuming that the water heater has 8 set temperatures (which is not limited to this, and is only used for illustration), the water consumption that can be supplied by the different set temperatures is:

the water consumption which can be supplied at the set temperature of 40 ℃ is 5 liters;

the water consumption which can be supplied at the set temperature of 45 ℃ is 8 liters;

the water consumption which can be supplied at the set temperature of 50 ℃ is 10 liters;

the water consumption which can be supplied by setting the temperature at 55 ℃ is 20 liters;

the water consumption which can be supplied at the set temperature of 60 ℃ is 25 liters;

the water consumption which can be supplied at the set temperature of 65 ℃ is 40 liters;

the water consumption which can be supplied at the set temperature of 70 ℃ is 50 liters;

the water supply at 75 c set temperature was 60 litres.

In this embodiment, the water consumption that can be supplied by different set temperatures is the water quantity that can be supplied within a preset temperature range in a unit time (for example, within one hour) when the water heater is at different set temperatures. The preset temperature range refers to a suitable temperature for the user to use water, and may be 38-50 ℃. For example, the above-mentioned water amount of 5 liters which can be supplied at the set temperature of 40 ℃ means that the water heater can supply 5 liters of water at the set temperature of 40 ℃ in the temperature range of 38 ℃ to 50 ℃ per hour. As another example, the above-mentioned water amount of 25 liters which can be supplied at the set temperature of 60 ℃ means that the water amount of 25 liters which can be supplied by the water heater at the set temperature of 60 ℃ in the temperature range of 38 ℃ to 50 ℃ per hour.

In this embodiment, it should be noted that the water consumption that can be supplied by different set temperatures does not concern the water temperature, but only concerns the water consumption that can be supplied by different set temperatures when the water temperature is within a certain preset temperature range. However, in other embodiments of the present invention, the water consumption that can be supplied by different set temperatures is unified to the water consumption that can be supplied at the standard temperature, and for the technical solution of this part, reference may be made to the following description of other embodiments.

In this embodiment, after obtaining the water consumption that can be supplied by the different set temperatures of the water heater, continue to carry out the next work, that is, according to the water consumption that corresponds to the different time periods of every day in the historical water consumption days and the water consumption that can be supplied by the different set temperatures of the water heater, determine the set temperatures that correspond to the different time periods of every day in the historical water consumption days respectively. In this step, it can be determined from a matching relationship between two water consumption amounts, for example, it is finally determined that:

the first day:

00:00-02:00: setting the temperature at 40 ℃ (because the water consumption of the setting temperature at 40 ℃ is 5 liters, the water consumption requirement of 0 liter in the time period can be met, and the principle like the above is followed and is not explained one by one);

04:00-06:00: setting the temperature at 40 ℃;

It should be noted that, in order to prevent the user's small probability water use event, the temperature may be set to be a lower 40 ℃ set temperature in the time period when the water use amount is 0, so as to ensure that the water use requirement of the user can be met when the user's temporary small probability water use event occurs. However, if the energy saving is concerned, the heating function can be turned off in the time period when the water consumption is 0, so as to save energy consumption. Therefore, the lower set temperature of 40 ℃ can be set or the heating function of the water heater can be turned off in the time period when the water consumption is 0 according to specific requirements.

After the set temperatures corresponding to different time periods of each day in the historical water consumption days are determined, the set temperatures corresponding to different time periods of each day in the future water consumption process of the water heater need to be predicted according to the above contents.

For example, for each time period, the highest set temperature corresponding to the time period in the 6 days may be selected as the set temperature prediction value corresponding to the time period. For example, for a time period 08:00-10:00 of a day, the corresponding maximum set temperature in the 6 days is the 55 ℃ set temperature, and therefore, the 55 ℃ set temperature may be taken as the set temperature prediction value corresponding to the time period. Further, the set temperature with the largest number of occurrences corresponding to the time period in the 6 days may also be selected as the set temperature prediction value corresponding to the time period. For example, also for a time period 08:00 to 10:00 of a day, the 55 ℃ set temperature appears 1 time, the 40 ℃ set temperature appears 2 times, and the 50 ℃ set temperature appears 3 times, and therefore, the 50 ℃ set temperature with the largest number of appearances can be taken as the set temperature prediction value corresponding to the time period. Furthermore, the predicted value of the set temperature corresponding to the time period can also be determined according to the voting result of the user on the set temperature which appears in the 6 days corresponding to the time period. For example, the voting results of the user for the set temperature that appears corresponding to the time period in the 6 days are 40 ℃ -0 tickets, 55 ℃ -0 tickets, and 50 ℃ -3 tickets, so that the set temperature of 50 ℃ at which the number of votes is the largest can be determined as the predicted value of the set temperature corresponding to the time period.

In this embodiment, it should be noted that two implementations of selecting the highest set temperature or the set temperature with the largest occurrence number as the set temperature prediction value corresponding to the time period are respectively given above. It is understood that the maximum set temperature is selected as the set temperature prediction value corresponding to the time period to satisfy the demand for hot water use, that is, the maximum set temperature is selected as the set temperature prediction value corresponding to the time period to consider the hot water satisfaction rate. The set temperature with the largest occurrence frequency is selected as the set temperature predicted value corresponding to the time period, so that the accuracy of the use of hot water can be met, namely the accuracy is considered by selecting the set temperature with the largest occurrence frequency as the set temperature predicted value corresponding to the time period. When the processing is actually carried out, the two factors can be comprehensively considered, and the processing is realized by setting a probability threshold. For example, when the frequency of occurrence of a certain set temperature exceeds the probability threshold, the set temperature is used as a set temperature predicted value corresponding to the time period, and if not, the highest set temperature is used as the set temperature predicted value corresponding to the time period.

In addition, in this embodiment, it should be noted that, when predicting the water consumption data based on the historical water consumption days, it is not preferable that the historical water consumption days are more, and actually, since the longer-term behavior has less influence on the current behavior, the longer-term behavior data needs to be appropriately "forgotten", and tests prove that the accuracy is affected by too many days or too few days, and the prediction result obtained for the 14 days of historical water consumption days is relatively good.

According to the technical scheme, the automatic control method of the water heater provided by the embodiment of the invention can predict the set temperatures of the water heater in different time periods corresponding to the future water using process according to the water consumption corresponding to different time periods in the historical water using process and the water consumption which can be supplied by the water heater at different set temperatures, and further control the water heater according to the predicted set temperatures of the water heater in different time periods corresponding to the future water using process. Therefore, the embodiment of the invention realizes the prediction of the set temperatures of the water heaters in different time periods corresponding to the future water consumption process by combining the water consumption corresponding to different time periods in the historical water consumption process and the water consumption capable of being supplied by different set temperatures of the water heaters, thereby providing the automatic control method of the water heater capable of self-adapting to the water consumption behaviors of the users, solving the problem that the users manually reserve the temperature of the water heater, and also enabling the water heater to run in a low-energy consumption mode on the premise of guaranteeing the water consumption requirement, thereby realizing the intelligent control of the water heater.

Based on the content of the foregoing embodiment, in this embodiment, the step 101 determines the water consumption corresponding to different time periods in the historical water consumption process, which may be specifically implemented as follows:

step 101': determining standard temperature water consumption corresponding to different time periods in the historical water consumption process; the standard temperature water consumption is the water consumption corresponding to the standard temperature condition by converting the water consumption corresponding to the different temperature conditions.

In this embodiment, in order to solve the problem that the water consumption can not be compared under different temperatures, this embodiment has adopted the water consumption under the different temperatures to standardize through unified standard temperature, obtains the mode of standard temperature water consumption. The processing mode of the embodiment has the advantages that: the problem of whether the water consumption corresponding to each time period has comparability when the temperature in the water heater is different in different time periods is not considered any more.

Based on the content of the foregoing embodiment, in this embodiment, the step 101' determines the standard temperature water consumption corresponding to different time periods in the historical water consumption process, which may be specifically implemented as follows:

step A1: determining actual water consumption, liner temperature and water inlet temperature corresponding to different time periods in the historical water consumption process;

step A2: determining standard temperature water consumption corresponding to different time periods in the historical water consumption process by utilizing a first preset standard temperature water consumption model according to actual water consumption, temperature in the liner and water inlet temperature corresponding to different time periods in the historical water consumption process; the first preset standard temperature water consumption model is a model representing the corresponding relation between actual water consumption and standard temperature water consumption under different liner temperatures and water inlet temperatures;

in this embodiment, when determining the standard temperature water consumption corresponding to different time periods in the historical water consumption process, the processing methods of steps a1-a2 are adopted, and the analysis is integrated to obtain that the actual water consumption corresponding to different time periods in the historical water consumption process can be converted into the standard temperature water consumption through the first preset standard temperature water consumption model. Because the actual water consumption corresponding to different time periods in the historical water consumption process is converted into the water consumption at the standard temperature, more accurate prediction results can be obtained when the actual water consumption is calculated and predicted according to the water consumption at the standard temperature corresponding to different time periods in the historical water consumption process, and the influence of fluctuation factors of different temperatures on the water consumption parameter is eliminated through the treatment.

In this embodiment, it can be understood that the first preset standard temperature water consumption model is a model representing a corresponding relationship between actual water consumption under different temperature conditions and standard temperature water consumption unified to the standard temperature conditions. In addition, in this embodiment, a specific form of the first preset standard temperature water consumption model is further specifically given:

wherein Q is₁Represents the water consumption at the first standard temperature, Q₀Represents the actual water consumption, T₁Indicating the temperature, T, in the bladder₀Denotes the standard temperature, T₂Indicating the temperature of the incoming water.

It should be noted that, the first preset standard temperature water consumption model mentioned in the embodiment is not limited to the above one form, and may also be other forms of models according to needs, such as:

wherein k is₁Denotes a first adjustment factor, the value of which can be set according to the actual requirement, k₁An adjusting factor, k, representing the influence of the difference between the inlet water temperature and the temperature in the liner and the standard temperature on the relation between the actual water consumption and the standard temperature₁The value of (A) is 0.8-0.95.

Based on the content of the foregoing embodiment, in this embodiment, the step 102 determines the water consumption that can be supplied by the water heater at different set temperatures, which can be specifically implemented by:

step 102': and determining the standard temperature water consumption which can be supplied by different set temperatures of the water heater.

In this embodiment, in order to solve the problem that the water consumption that the water heater can supply at different set temperatures cannot be well unified, this embodiment adopts a mode that the water consumption that the different set temperatures of water heater can supply is standardized through unifying standard temperature so as to obtain the standard temperature water consumption that the different set temperatures of water heater can supply. The processing mode of the embodiment has the advantages that: no longer considering the question of whether the water consumption can be supplied at different set temperatures is comparable.

Based on the content of the foregoing embodiment, in this embodiment, the step 102' determines the water consumption at the standard temperature that can be supplied by the water heater at different set temperatures, which can be specifically implemented as follows:

step B1: determining rated capacity of the water heater;

step B2: according to different set temperatures of the water heater, the inlet water temperature and the rated capacity of the water heater, determining standard temperature water consumption which can be supplied by the different set temperatures of the water heater by utilizing a second preset standard temperature water consumption model;

In this embodiment, when the standard temperature water consumption that the different temperature settings of definite water heater can be supplied is being determined, the processing mode of step B1-B2 has been adopted, it can know to synthesize the analysis, predetermine standard temperature water consumption model through the second and can turn into standard temperature water consumption with the water consumption that different temperature settings can be supplied, thereby obtain the standard temperature water consumption that different temperature settings can be supplied, and then make follow-up when utilizing the standard temperature water consumption that different temperature settings can be supplied and the standard temperature water consumption that different time quantums correspond in the historical water process to match, can obtain more accurate matching result.

In addition, in this embodiment, a specific form of the second preset standard temperature water consumption model is further specifically given:

wherein Q is₂To representWater consumption at the second standard temperature, Q represents rated capacity of the water heater, T₃Indicating the set temperature, T₀Denotes the standard temperature, T₂Indicating the temperature of the incoming water.

It should be noted that the second preset standard temperature water consumption model mentioned in this embodiment is not limited to the above-mentioned one form, and may also be other forms of models according to needs, such as:

wherein k is₂Represents a second adjustment factor, the value of which can be set according to the actual need, k₂An adjustment factor, k, representing the magnitude of the effect of the difference between the inlet water temperature and the set temperature and the standard temperature in the water heater on the relationship between the rated capacity of the water heater and the standard temperature water consumption that the water heater can supply₂Is 0.7-0.95.

Based on the content of the foregoing embodiment, in this embodiment, the step 103 predicts the set water heater temperatures in different time periods corresponding to the future water usage process according to the water usage amounts corresponding to different time periods in the historical water usage process and the water usage amounts that can be supplied by different set water heater temperatures, and may specifically be implemented as follows:

step 103': and predicting the set temperatures of the water heaters in different corresponding time periods in the future water using process according to the standard temperature water consumption corresponding to different time periods in the historical water using process and the standard temperature water consumption which can be supplied by the water heaters at different set temperatures.

In this embodiment, it should be noted that, as the processing in the above embodiments is performed, the standard temperature water consumption corresponding to different time periods in the historical water consumption process and the standard temperature water consumption capable of being supplied by different set temperatures of the water heater are obtained, and then the set temperatures of the water heater corresponding to different time periods in the future water consumption process are predicted in a manner of mutually matching and mapping the standard temperature water consumption according to the standard temperature water consumption corresponding to different time periods in the historical water consumption process and the standard temperature water consumption capable of being supplied by different set temperatures of the water heater. When the standard temperature water consumption matching mapping is carried out, a principle needs to be followed, namely that the standard temperature water consumption which can be supplied by the water heater is more than or equal to the standard temperature water consumption corresponding to the corresponding time period in the historical water consumption process, and the standard temperature water consumption corresponding to the corresponding time period in the historical water consumption process needs to be closest to the standard temperature water consumption.

In addition, when standard temperature water consumption matches the mapping, can also utilize two to set up the water consumption interval that corresponds between the temperature to carry out the discretization processing to the standard temperature water consumption that different time quantums correspond among the historical water use process, avoid the influence of the abnormal data of sensor to the result. For example, assume that the standard temperature water usage that can be supplied at the 40 ℃ set temperature is 10 liters; if the water consumption which can be supplied by the set temperature of 45 ℃ is 15 liters, the corresponding water consumption (15-10 to 5 liters) between the set temperature of 40 ℃ and the set temperature of 45 ℃ can be used for discretizing the water consumption at the standard temperature corresponding to different time periods in the historical water using process, that is, the water consumption at the standard temperature corresponding to different time periods in the historical water using process is processed into discrete data points of 5 liters, 10 liters, 15 liters, 20 liters and 25 liters.

Based on the content of the foregoing embodiment, in this embodiment, the step 103' predicts the set water heater temperatures in different time periods corresponding to the future water use process according to the standard temperature water consumption corresponding to different time periods in the historical water use process and the standard temperature water consumption that can be supplied by different set water heater temperatures, and may be specifically implemented by the following manners:

step C1: determining the set temperature of the water heater corresponding to different time periods in the historical water consumption days according to the standard temperature water consumption corresponding to different time periods in the historical water consumption days and the standard temperature water consumption which can be supplied by the water heater at different set temperatures;

step C2: according to the set temperatures of the water heaters corresponding to different time periods in one day in the historical water consumption days, the set temperatures of the water heaters corresponding to different time periods in one day in the future water consumption process are predicted.

In this embodiment, the set temperatures of the water heaters corresponding to different time periods of a day in the historical water consumption days are determined according to the standard temperature water consumption corresponding to different time periods of the day in the historical water consumption days and the standard temperature water consumption capable of being supplied by different set temperatures of the water heaters, and then the set temperatures of the water heaters corresponding to different time periods of the day in the future water consumption process are predicted according to the set temperatures of the water heaters corresponding to different time periods of the day in the historical water consumption days.

Based on the content of the foregoing embodiment, in this embodiment, the step C2 is to predict the set temperatures of the water heater at different time periods corresponding to different days in the future water usage process according to the set temperatures of the water heater at different time periods corresponding to different days in the historical water usage days, and may specifically be implemented as follows:

step C21: sending the set temperatures of the water heater corresponding to different time periods in the historical water consumption days to user side equipment;

step C22: receiving voting values of the set temperatures of the water heaters corresponding to different time periods in one day, which are sent by user side equipment;

step C23: and predicting the set temperature of the water heater at different time periods corresponding to one day in the future water using process according to the voting values of the set temperature of the water heater at different time periods corresponding to one day.

In the embodiment, the set temperatures corresponding to different time periods of a day in the future water using process of the water heater are determined through a temperature voting mechanism. In this embodiment, a probability threshold may be set, and the larger the probability threshold, the lower the tolerance to the small probability water consumption event, for example, for the set temperature of a certain time period of history for 6 days (the set temperature matched in step 103), a voting mechanism is used to vote for the set temperature that should be set for the time period in the future day, where the voting mechanism is: and sending the set temperatures of the water heaters corresponding to different time periods in the historical 6 days to user end equipment, and then voting the set temperatures of the water heaters corresponding to different time periods in the historical 6 days by the user respectively. For example, it is assumed that the set temperatures corresponding to the time periods 00:00-02:00 in the history 6 days are determined to be 40 ℃, 45 ℃, 40 ℃ and 40 ℃ after matching in step 103, then the set temperatures are sent to the user, the user votes for the set temperatures, and finally the statistical voting result is: the vote value for the 40 ℃ setting temperature was 5, and the vote value for the 45 ℃ setting temperature was 1, and it was found that the vote ratio for the 40 ℃ setting temperature was 5/6-0.83, and the vote ratio for the 45 ℃ setting temperature was 1/6-0.16. When the ratio of the number of votes at a certain set temperature (which means the ratio of the number of votes at a certain set temperature to the number of days of historical water use) exceeds a set probability threshold (which may be 0.8), the set temperature is set as a predicted set temperature for the time zone of the day in the future (also referred to as a predicted value of the set temperature corresponding to the time zone). As can be seen from the above example, for the time period 00:00-02:00 of the 6 days of the above example, the vote ratio of the 40 ℃ set temperature exceeds the set probability threshold of 0.8, and therefore the 40 ℃ set temperature can be taken as the predicted set temperature for that time period on the future day. When the user votes and finds that the set temperature vote ratio does not exceed the set probability threshold, the highest gear of all the corresponding set temperatures in the history is selected as the predicted set temperature of the time period in the future day, for example, for the time period 00:00-02:00 in the 6 days of the above example, the set temperature of 45 ℃ is selected as the predicted set temperature of the time period in the future day (as in the scheme described in the following embodiment).

As can be seen from the above solution, in the present embodiment, because the temperature voting mechanism is utilized, the set temperature at which the ratio of votes exceeds the set probability threshold is used as the predicted set temperature, so that the predicted set temperature can be guaranteed to be in accordance with the water consumption behavior of the user with the maximum probability. In addition, the embodiment carries out probability estimation on the accidental water use event, and realizes tolerance control on the water use event with small probability by controlling the probability threshold parameter.

In this embodiment, different from the above embodiments, the highest set temperature of all set temperatures in different historical water consumption days corresponding to each time period is directly used as the predicted value of the set temperature corresponding to different time periods in a future water consumption process without using a voting mechanism, so that it is ensured that the predicted set temperature can meet the water consumption demand of the user with the maximum probability.

It should be noted that the number of days of historical water usage described in the present embodiment is, by default, a number of consecutive days of historical water usage, but if the water heater does not have consecutive days of historical water usage, the date of missing water usage data may be ignored. However, in practical applications, the number of days for which water use data is allowed to be lost may be set, and when the number of days for which water use data is lost exceeds the number of days for which water use data is allowed to be lost, the water heater is not predicted. If the number of days for which water consumption data is missing exceeds 3 days, the water heater is not predicted. For example, when the device does not have 14 consecutive days of data, the last 14 days of data may be selected, ignoring the missing date. The number of missing days allowed in this example is 3 days, and the water heater is not predicted beyond 3 days.

Based on the content of the foregoing embodiment, in this embodiment, the automatic control method for a water heater further includes:

In the embodiment, in order to realize the fine prediction of the water heater in each time period of the future day, the external air temperature data is further considered, which is particularly important for the areas with obvious outdoor air temperature change. The specific implementation method is different from the embodiment in that after the set temperatures corresponding to different time periods of a day in the future water using process are obtained, the set temperatures corresponding to different time periods of the day in the future water using process are corrected by using the air temperature data corresponding to different time periods of the day in the future water using process, and then the water heater is automatically controlled by using the corrected set temperatures. Specifically, when the correction is performed, the correspondence relationship may be adopted such that the set temperature increases by 5 degrees (not more than 75 degrees at the maximum) for each 10 degrees decrease in the air temperature.

In this embodiment, after the implementation of the automatic control method for a water heater provided by this embodiment is further provided, the electricity consumption cost can be saved, so that the user can visually see the electricity saving amount, and the user experience can be improved.

In this embodiment, first, when the water heater is turned on, the original set temperature data before the water heater is turned on is recorded (if the water heater is not turned on, the water heater will heat and keep warm at the original set temperature), and after the water heater is turned on, the water heater will automatically adjust the predicted set temperature output by this embodiment. The power saving amount after the function is started is estimated by a fitting formula by using the original set temperature, the predicted set temperature output by the embodiment, the ambient temperature and the water consumption data. After the electricity saving amount is calculated, the heating time of the equipment, the rated power of the equipment and the step electricity price data of the local area are obtained, and the electricity consumption amount during the running period of the equipment is calculated. And then calculating the saved electricity fee (electricity consumption + electricity saving amount) 1-electricity consumption 2 according to the step electricity price. Wherein electricity prices 1 and 2 are stepped electricity prices.

According to the above description and analysis, the automatic control method for the water heater provided by the embodiment can adapt to the water consumption behavior of the user, so that the water heater can operate in a low energy consumption mode on the premise of guaranteeing the water consumption requirement. In addition, the embodiment also utilizes a temperature voting mechanism, and the temperature with the ratio of the votes exceeding the set probability threshold is used as the predicted set temperature, so that the set temperature can be ensured to be in accordance with the water using behavior of the user with the maximum probability. In addition, in another embodiment, the maximum temperature is used as the predicted set temperature, which ensures that the set temperature meets the water demand of the user with the maximum probability.

In addition, the embodiment can also tolerate a certain degree of data loss, because the water usage habit of the user in a certain period of time in a short period of time changes little, and therefore even if the data in a certain period of time is lost in a certain day, the final prediction result is not influenced significantly.

In addition, the present embodiment can also allow a certain degree of abnormal value, because the present embodiment discretizes the actual standard temperature water consumption by the standard temperature water consumption corresponding to the temperature interval, it can effectively avoid the influence of the maximum or minimum abnormal value on the result.

In this embodiment, it should be noted that the automatic control method of the water heater provided in this embodiment may be applied to a water storage type electric water heater for water used for bathing or dining. Of course, the present invention is not limited to this, and the automatic control method of the water heater provided in this embodiment can also be used in water storage type electric water heaters for other purposes according to actual needs.
