[0029] The use of water heaters in general households has a strong regularity, and maintaining a large amount of hot water in the water heater for a long time will undoubtedly cause a great waste of energy. The heating strategy of the water heater can be guided by analyzing the user's water use habits and predicting the user's water use time, thereby improving the efficiency of energy utilization and achieving the purpose of energy saving. Therefore, in an embodiment of the present invention, a heating control method for a water heater is provided, which can predict the user's water use time according to the user's water use habits, locate the possible time point when the user's water consumption is large, and adopt two different heating strategies according to the predicted water use time to achieve the purpose of energy saving. The heating control method of the water heater is described below through a specific embodiment.

[0030] Example 1

[0031] According to an embodiment of the present invention, a method embodiment of a heating control method for a water heater is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 1 is a flow chart of a heating control method for a water heater according to an embodiment of the present invention. Figure 1 As shown, the heating control method of the water heater includes the following steps:

[0033] Step S102, obtaining first water use data, wherein the first water use data is water use data collected in a first historical period, and the water use data includes: water use time, water use amount, water use frequency, and water use temperature.

[0034] Optionally, in the embodiment of the present invention, the water use data (first water use data, second water use data) may include: water use time, water use amount, water use frequency, water use temperature. Of course, other data may also be included, which is not specifically limited here.

[0035] Optionally, the first historical time period may be the day before the current date or the n days before the current date.

[0036] In an optional solution, water use data of the day before the current date may be obtained, for example, the time periods of water use of the previous day, the amount of water used each time, the frequency of water use, and the water temperature of each water use.

[0037] Step S104, using a water use scenario determination model to determine a first water use scenario corresponding to the first water use data, wherein the water use scenario determination model is obtained by machine learning training using multiple sets of training data, and each set of training data includes: water use data, and a water use scenario corresponding to the water use data, where the water use scenario represents a water use method.

[0038] Optionally, in this embodiment, the water usage scenario determination model may be pre-trained.

[0039] In an optional solution, the first water use data may be input into a water use scenario determination model, and the water use scenario determination model may be used to determine a water use scenario corresponding to the first water use data (i.e., the first water use scenario). For example, the water use data of the day before the current date may be converted into an input of a water use scenario determination model, and the water use scenario of the current date may be predicted based on the output of the water use scenario determination model.

[0040] Step S106: determining a heating strategy for the water heater based on the first water usage scenario.

[0041] In this embodiment, a heating strategy may be generated according to the water usage scenario determined in step S104 to control the operation of the water heater.

[0042] Step S108, controlling the water heater to operate according to the heating strategy.

[0043] From the above, it can be seen that in the scheme recorded in Example 1 of the present invention, after obtaining the water use data of the previous day, it can be used as the input of the water use scenario determination model, and the water use scenario determination model is used to obtain the water use scenario of the next day, so as to determine the water heater heating strategy of the next day, and control the operation of the water heater based on the heating strategy, thereby achieving the purpose of guiding the heating strategy of the water heater by predicting the user's water use time.

[0044] It is easy to notice that since the water use time of the next day can be predicted based on the water use data of the previous day, the water use time of the next day can be predicted by determining the model through the water use scenario on the basis of the original basic heating function of the water heater, which is convenient for water use. Therefore, the heating control method of the water heater provided by the embodiment of the present invention can provide more intelligent services on the basis of the original basic heating function of the water heater, improve the user's water use experience, and achieve the purpose of energy saving.

[0045] Therefore, the solution provided by Example 1 of the present invention solves the technical problem in the related art that the water heater has a relatively low intelligence level and cannot be reasonably and accurately controlled, resulting in waste of electric energy.

[0046] According to the above embodiment of the present invention, the heating control method of the water heater may further include: obtaining second water use data collected within multiple water use data collection cycles, wherein the water use data collection cycle is obtained by dividing the historical time period according to a predetermined time length; classifying the second water use data to determine a second water use scenario corresponding to the second water use data; using the second water use data and the second water use scenario to train the initial network model to obtain a water use scenario determination model, wherein the initial network model is the network structure of the water use scenario determination model.

[0047] Optionally, the historical time period may be n days before the current date. The water consumption data collection cycle may be for each day, and the water consumption data may be divided into 24 time periods per hour.

[0048] Since the hidden Markov model is simple to calculate, can add new data from users every day to update the model, and focuses on the correlation between the previous and next data, it is more in line with the user's water use habits. Therefore, the above initial network model can be a hidden Markov model.

[0049] In the above embodiment, before classifying the second water use data and determining the second water use scenario corresponding to the second water use data, the heating control method of the water heater also includes: determining a water use data classification strategy; wherein, determining the water use data classification strategy includes: when the water use data within a predetermined time period meets a first preset condition, determining that the water use scenario is water use scenario one, wherein the first preset condition includes at least one of the following: the water use amount does not exceed the predetermined water use amount, the water use temperature is lower than the predetermined water use temperature, and the water use frequency is greater than the predetermined frequency; when the water use data within the predetermined time period meets the second preset condition, determining that the water use scenario is water use scenario two, wherein the first preset condition includes at least one of the following: the water use amount exceeds the predetermined water use amount, the water use temperature is greater than or equal to the predetermined water use temperature, and the water use frequency is less than or equal to the predetermined frequency.

[0050] Optionally, the water use data may be classified according to water use time, water use frequency, water use amount, etc., and the corresponding water use scenarios may be determined.

[0051] For example, in daily use scenarios such as washing hands and washing face, which are used frequently and in small quantities, the required water temperature is often low, the water consumption is small, the frequency of occurrence is high, and it is difficult to predict, so it is determined as water use scenario one; in large-scale use scenarios such as bathing, which are used frequently and in small quantities, the required water temperature is often high, the water consumption is large, the frequency of occurrence is low, the regularity is strong, and it can be predicted, so it is determined as water use scenario two.

[0052] According to the above embodiment of the present invention, the initial network model is trained using the second water use data and the second water use scenario, including: converting the second water use data into input information of the initial network model; inputting the input information into the initial network model to obtain output information of the initial network model; converting the output information into a third water use scenario; and looping through the above steps until the third water use scenario is the same as the second water use scenario for a number of times greater than a predetermined threshold.

[0053] In an embodiment of the present invention, the user's water consumption data can be collected first, and the daily data can be divided into 24 time periods on an hourly basis. When the total water consumption within the hour exceeds a threshold, it is determined that water use scenario 2 has occurred. Taking into account the impact of the use environment on the user's water use habits, the user's water use data is divided into different categories on a daily basis according to the use environment conditions, such as: the weather and temperature of the day, whether it is a holiday, etc.; a hidden Markov model modeled using historical data of the same category is called to obtain the probability of water use scenario 2 occurring in different time periods of the day. When the probability is greater than a threshold, it is determined that water use scenario 2 will occur in the time period, and if the probability is less than the threshold, it is determined that water use scenario 1 will occur.

[0054] According to the above embodiment of the present invention, a heating strategy for the water heater is determined based on a first water use scenario, including: obtaining the current ambient temperature; when the water use scenario is water use scenario one, heating the water in a water tank of the water heater according to the current ambient temperature, and controlling the water in the water tank to remain within a first temperature range; when the water use scenario is water use scenario two, determining a first heating start time of the water heater according to the current ambient temperature and the heating power of the water heater, and when the first heating start time arrives, heating the water in the water tank, and controlling the water in the water tank to remain within a second temperature range.

[0055] In this embodiment, when the next time period is determined as scenario 1, a lower temperature is maintained according to the current temperature, and the specific value needs to be determined by user experience experiments. On the contrary, when a time period is determined as scenario 2, a heating start time is determined according to the current temperature and the heating power of the water heater, and the water in the water heater is heated in advance to ensure that the water temperature is maintained at a higher level during the time period. In this way, users can be provided with more suitable hot water, which improves the user's water use experience.

[0056] According to an embodiment of the present invention, the heating control method of the water heater may further include: in the process of controlling the water in the water tank to maintain a first temperature range, if a water temperature adjustment instruction is received, starting the instant heating device of the water heater to heat the water in the water tank.

[0057] In this embodiment, during the heating process using the heating strategy under the water usage scenario, when the user controls and requires a higher temperature, the instant heating device at the water outlet is turned on to compensate for the water temperature, making the control of the water heater more flexible and better able to meet user needs.

[0058] According to the above embodiment of the present invention, the heating control method of the water heater may also include: when the water use scenario is water use scenario one, determining a second heating start time for heating the water in the water tank; when the first heating start time is the same as the second heating start time, preferentially executing the heating strategy corresponding to water use scenario two.

[0059] Due to the water use scenario, the water heater will correspond to a heating start time, that is, the second heating start time; the heating start time of water use scenario two (the first heating start time) may conflict with the second heating start time. At this time, the heating strategy corresponding to the water use scenario two is executed first, thereby meeting the user's demand for large amounts of water.

[0060] The heating control method of a water heater provided by an embodiment of the present invention is described below with reference to the accompanying drawings. Figure 2 is a flow chart of an optional water heater heating control method according to an embodiment of the present invention, such as Figure 2 As shown, the user's water usage data is first collected, then the collected water usage data is classified, and then the hidden Markov model is used to predict the water usage scenario. If the prediction result is water usage scenario two, the heating control method corresponding to water usage scenario two is executed. Otherwise, it is determined whether the next time period is water usage scenario two. If so, the heating control method corresponding to water usage scenario two is executed; otherwise, the heating control method corresponding to water usage scenario one is executed.

[0061] According to the heating control method for a water heater provided by an embodiment of the present invention, the user's water consumption data is first collected, and the daily data is divided into 24 time periods per hour. When the total water consumption within the hour exceeds a threshold, it is determined that scenario 2 occurs. Considering the possible impact of the use environment on the user's water use habits, the user's water consumption data is divided into different categories by day according to the use environment conditions, such as: the weather, temperature, whether it is a holiday, etc. of the day; then the hidden Markov model modeled using historical data of the same category is called to obtain the probability that scenario 2 will occur in different time periods within the day. When the probability is greater than a threshold, it is determined that scenario 2 will occur within the time period, and when the probability is less than the threshold, scenario 1 is determined to occur. When the next time period is determined to be scenario 1, a lower temperature is maintained according to the current temperature, and the specific value needs to be determined by user experience experiments. At the same time, when the user control requires a higher temperature, the instant heating device at the water outlet is turned on to compensate for the water temperature. When a time period is determined to be scenario 2, a heating start time is determined according to the current temperature and the heating power of the water heater, and the water in the water heater is heated in advance to ensure that the water temperature is maintained at a higher temperature within the time period. When there is a conflict with the time period control of scenario 1, this control is executed first.

[0062] From the above, it can be seen that since water use scenario one corresponds to a small amount of water used by the user, the user's requirements for temperature are not high in this scenario. During the time period predicted for scenario one, a lower temperature is maintained according to the current temperature (the specific temperature needs to be experimentally obtained to obtain a comfortable temperature under the corresponding temperature). When the user manually sets a higher temperature in scenario one, the water temperature is compensated by opening the instant heating device at the water outlet. The user can also manually set the change scene to scenario two. Scenario two corresponds to users using a large amount of water in small amounts and requiring a higher water temperature. In order to ensure a higher water temperature in the corresponding time period, it is necessary to plan for early heating. If the early heating time period coincides with the time of scenario one, heating is performed first.

[0063] Therefore, the heating control method for the water heater provided by the embodiment of the present invention can collect the user's water use data, and predict the user's large water use time of the next day through the hidden Markov model; and according to the water use habits of ordinary families and the temperature conditions at the time, in the time period when the user uses a small amount of water multiple times, maintain a lower temperature, and use the outlet instant heating device for temperature compensation; in the time period when the user uses a large amount of water, maintain a higher temperature to meet the user's water demand. It has the following beneficial effects: 1) predict the user's water use time through the user's water use habits, and locate the possible time point when the user's water consumption is large; 2) according to the predicted water use time, adopt two different heating strategies to achieve the purpose of energy saving, effectively reducing the disadvantage that mainstream water heaters can only arrange heating strategies through user control, but cannot flexibly allocate heating strategies.

[0064] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0065] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.
