Home appliances can be controlled to perform corresponding operations through mobile devices or voice interaction. For water heaters, users can set the desired temperature according to their needs and make an appointment with the water heater for a specific time.

[0003] However, in many cases, users cannot reasonably arrange the use of the water heater and cannot meet the heating conditions of the water heater, so that users cannot use the water heater on time after returning home, resulting in a long waiting time before using it. At the same time, the water heater cannot intelligently customize the appropriate operating temperature for users, affecting the user experience.

[0049] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0052] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0053] Water heaters are essential household appliances in family life scenarios. They provide services for a variety of household water use scenarios, and after loading the Internet of Things function, the intelligent functions they possess bring convenience to users. Users can set their favorite temperatures through a variety of communication methods. Since there is a certain pre-heating time, users can also make reservations in advance and set the required usage time. However, users usually cannot reasonably arrange their water heater usage needs, resulting in that even if an appointment is made, the reservation conditions provided may not meet the water heater operation. For example, the time is too short or the set heating power is too low, which may cause the water heater to fail to complete heating at the preset time point, and the water heater cannot intelligently judge this problem. At the same time, according to the environmental conditions on the user's way home, the user's demand for the water heater temperature may change, but the water heater cannot intelligently judge this situation. In addition, unreasonable use by users may also lead to waste of electricity. For example, after the water heater is turned on, the user cannot use the water heater due to an emergency, and forgets to turn off the water heater. The water heater continues to heat or enters the insulation state, which will increase excess energy consumption and cause waste.

[0054] Based on the above problems, the present application provides a control method for a water heater. When the user issues a control command for the water heater in advance, the water heater obtains the current location of the user, thereby determining the distance and time from the user to the home, and calculating the heating time and the start time of the water heater according to the user's preset target temperature. When the user is far away from home and the travel time is greater than the heating time, it is possible to determine whether the heating temperature needs to be adjusted based on the weather conditions corresponding to the user's real-time location, and at the same time, determine whether the water heater needs to be turned on based on the user's location at the start time. After the preset time, based on the user's real-time location, if the user is getting farther and farther away from home or the location has not changed for a long time, it is possible to confirm with the user whether the water heater needs to be turned off, thereby avoiding the problem of increased energy consumption of the water heater when the user changes the plan and does not want to use it. At the same time, the method also intelligently formulates a pre-heating plan based on user information, thereby enhancing the user experience.

[0055] Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1As shown, the mobile terminal 101 can establish a communication connection with the water heater 102, wherein the water heater 102 also includes a temperature sensor 103, which can obtain the water temperature before heating, so that the water heater 102 can determine the time and power required for heating to the target temperature, and stop heating the water heater 102 when the target temperature is heated. Specifically, when the user issues a control instruction for the water heater through the application in the mobile terminal 101, the water heater 102 can access the user's location information through the application in the mobile terminal 101, so as to determine the distance and time from the user to the home, and the water heater 102 stores the user's preset target temperature. Based on the arrival time and the target temperature, the start time of the water heater 102 can be determined. When the user's journey time is longer than the heating time, the environmental information corresponding to the user's real-time location can be obtained to determine whether the ambient temperature has changed, so as to adjust the target temperature. At the same time, according to the user's real-time location, when the user's location is indeed getting closer to home, indicating that the user is on the way back home, the water heater is controlled to start normally. In another case, when the user's location has not changed for a period of time or is getting farther and farther away from home, an inquiry message can be sent to the user through the mobile terminal 101 to confirm whether the water heater 102 needs to be turned off.

[0056] In addition, if the default power used in the interval between the current time when the user sends the instruction and the expected time of arrival at home cannot meet the heating needs, the current water temperature can be obtained through the temperature sensor 103, so as to calculate the additional power required to heat to the target temperature, thereby ensuring that the water can be heated to the target temperature when the user is expected to arrive home.

[0057] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0058] Figure 2 The process of the water heater control method provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the method includes:

[0059] S201. According to the user's water heater control instruction, obtain the user's current location information, preset target temperature and heating time, and obtain the user's first distance from home, estimated arrival time and water heater target start time according to the current location information.

[0060] Specifically, when the water heater receives a control instruction from the user, the water heater can access and obtain the user's location information through the application in the mobile terminal. For example, the water heater control instruction can be the option of turning on the water heater when returning home selected by the user through the application. After the user selects, the water heater is configured to automatically obtain the user's location information. In addition, if the user has not set the heating temperature, the user can be guided to set the heating temperature after receiving the control instruction as the preset target temperature for subsequent use. At the same time, a default heating power can be set in the water heater. The characteristic of the heating power can be the heating power under the average energy consumption of the water heater, with less loss to the heating element and higher safety. At the same time, since the water temperature changes according to the ambient temperature, the current water temperature can be obtained through the temperature sensor in the water heater, and the required heating time can be calculated in combination with the preset heating power and the target temperature.

[0061] Based on the user's location information, the user's first distance from home and the estimated time of arrival can be determined. Specifically, the user can be guided to preset the location of the home in the application. Based on the preset location and current location, the application can automatically calculate the distance and arrival time, and send them to the water heater. Alternatively, the water heater can calculate the distance and time between the user's current location and the location of the water heater based on its own positioning device. There is no limitation here. The estimated time of arrival is a specific time point. For example, the time it takes for the user to get home can be calculated based on the user's location information and moving speed, thereby determining the estimated time of arrival. Based on the target temperature, the water heater can determine the time required to heat from the current temperature to the target temperature, and use the estimated time of arrival as the heating completion time to reversely calculate the time when the water heater starts heating.

[0062] In other embodiments, a default temperature may be provided to the user, which is consistent with human perception, and may be adjusted for the user according to the ambient temperature in different seasons. The ambient temperature and the heating temperature are negatively correlated.

[0063] S202: When a first interval between the current time and the expected arrival time is greater than the heating time, obtaining the real-time location of the user and environmental information corresponding to the real-time location, wherein the environmental information includes at least one of temperature, humidity or sunlight intensity.

[0064] In this step, when the first interval time between the current time and the expected arrival time is greater than the heating time, it means that the user has a long way to go home, and the environmental conditions may be different throughout the journey. For example, when traveling across regions in a city, the weather may change. During the journey, the starting time is sunny, and then the weather turns cloudy and rainy, and the humidity, temperature, etc. may change. Or the area where the starting point is located is relatively hot, while the temperature in the area where the home is located is relatively low. Therefore, the environmental conditions during the user's journey can be obtained to determine whether it is necessary to lower the target temperature to give the user a shower or increase the target temperature to warm up the user. The temperature, humidity or sunlight intensity in the environmental information may affect the user's physical sensation, so this type of information can be extracted for reference.

[0065] S203. Acquire a correction parameter of the target temperature according to the environmental information corresponding to the real-time position, and heat the water heater at the corrected target temperature, wherein the correction parameter is a positive number or a negative number.

[0066] In this step, according to the changes in the environment during the journey, for example, the changes in temperature, humidity or light within a certain period of time can be confirmed, and the target temperature that needs to be increased or decreased can be confirmed based on the difference in changes. The adjusted numerical part is the correction parameter, and a relationship between the environmental information and the correction parameter can be set. The correction parameter is calculated based on the relationship. It can be understood that the correction parameter may be a positive number or a negative number. The existing target temperature and the correction parameter are directly added together to obtain the corrected target temperature. Since the preset target temperature is already a value within the temperature range suitable for the human body, the correction parameter does not need to be very large, so it has little effect on the heating power, and even if the temperature is increased, the heating can be completed within the heating time.

[0067] S204. According to the real-time location, when the target start time arrives, if it is determined according to the real-time location information that the second distance the user is currently away from home is less than the first distance, control the water heater to turn on.

[0068] In this step, based on the user's real-time location, it can also be determined whether the user continues to move toward home as planned. When the target start time arrives, if the user's location change shows that the current second distance is less than the first distance, it means that the plan has not changed, and the water heater is controlled to turn on.

[0069] Exemplarily, if the second distance is greater than or equal to the first distance, an inquiry message is sent to the user terminal, and the inquiry message is used to determine from the user whether to turn on the water heater.

[0070] Specifically, when the current second distance is greater than or equal to the first distance, it means that the user has not moved towards home as planned, but is getting farther and farther away from home, or remains at the current position and does not change. This situation may be that the user has other temporary arrangements and cannot return home on time. Therefore, at this time, it is possible to confirm with the user whether the water heater needs to be turned on to avoid the user changing the plan but forgetting to turn off the water heater, causing excess energy consumption or safety hazards.

[0071] Exemplarily, when the user still chooses to start the water heater normally, after the target start time, the following steps are also included:

[0072] After the preset time is reached, the third distance of the user from home is obtained, and when the third distance is greater than or equal to the second distance, an inquiry message is sent to the user end, and the inquiry message is used to determine whether to turn off the water heater from the user.

[0073] The main purpose of this step is that after the preset time has passed after the water heater is turned on, if the user has not changed his status, but keeps getting farther and farther away from home or does not change from the previous location, this situation may still indicate that the user has other temporary arrangements and cannot return home. At this time, a second inquiry message can be sent to the user to confirm whether to turn off the water heater, so as to avoid the user being unable to return home but forgetting to turn off the water heater, resulting in unnecessary energy consumption and safety hazards.

[0074] The water heater control method provided in the present embodiment obtains the user's current location information, preset target temperature and heating time according to the user's water heater control instruction, so as to determine the estimated arrival time at home and the target water heater start time, and when the journey time is longer than the heating time, the target temperature is corrected according to the environmental information during the journey. When the target start time is reached, if the user's real-time location indicates that the distance to home is getting closer, the water heater is turned on at this time; if the real-time location shows that the user's location is getting farther away from home or the location has not changed, the user is asked to confirm whether to continue to perform subsequent operations. The method is based on the user's usage needs and intelligently formulates a heating plan based on user information, so that the user can use the water heater immediately and comfortably when returning home. In addition, the intelligent reminder service can also improve safety, reduce energy consumption, and enhance user experience.

[0075] Figure 3 The process of the water heater control method provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, the process of correcting the target temperature of the water heater according to the environmental information is described in detail. The method includes:

[0076] S301: When a first interval between the current time and the expected arrival time is greater than the heating time, obtain a real-time location of the user and environmental information corresponding to the real-time location.

[0077] In this step, the user's location and corresponding environmental information can be obtained once or multiple times at a fixed preset period during the user's journey. By capturing environmental information at intervals of a certain length of time, the changes can be captured more obviously in the subsequent acquisition of environmental change information, and the environmental conditions are more likely to change easily.

[0078] S302: Determine whether the temperature, humidity or sunshine intensity in the environmental information changes from the start time to the end time of the preset cycle.

[0079] In this step, the environmental information at the start time of the preset cycle is compared with the environmental information at the end time to confirm whether there is any change, which includes but is not limited to changes in temperature values, changes in humidity values, or changes in sunlight intensity values. In addition, there is a situation where the interval between the current time and the target opening time is less than a preset cycle, and this situation needs to be identified.

[0080] Exemplarily, determining whether the second interval between the current time and the target start time is greater than the preset period;

[0081] If not, judging whether the second environment information has changed relative to the first environment information when the target start time arrives based on the first environment information of the current time and the second environment information of the target start time;

[0082] If yes, then obtain the ratio of the second interval duration to the preset period, the ratio represents the number of the preset periods, and when the ratio is a non-integer, perform an upward modulus calculation;

[0083] At the end of each preset period, it is determined whether the second environment information has changed relative to the first environment information.

[0084] S303: If yes, obtain the change item and the corresponding change difference in the environmental information.

[0085] According to the confirmed change of the environmental information, a change difference corresponding to the change item is obtained, where the difference is the difference between a value corresponding to the end time of a cycle and a value corresponding to the start time.

[0086] S304: Obtain a sub-correction parameter corresponding to at least one change item, where the sub-correction parameter represents a product of a single change difference and a corresponding correction coefficient.

[0087] In this step, each indicator in the environmental information, including but not limited to temperature, humidity or light intensity, can correspond to a correction coefficient respectively. The correction coefficient reflects the preset relationship between the adjusted temperature and the indicator, indicating that after the indicator changes, the numerical value corresponding to the adjusted part is suitable for the user's perception. Generally, the correction coefficient is a negative value, indicating that the adjustment of the target temperature is opposite to the environmental change. For example, a decrease in temperature, humidity or sunlight intensity all correspond to an increase in the target temperature. The value of the correction coefficient can be obtained through analysis of a large amount of experimental data and is not limited here.

[0088] The product is calculated based on the change difference of each change item and its correction coefficient to obtain a sub-correction parameter corresponding to each change item, and the sub-correction parameter represents the adjustment value of the target temperature indicated by the single change item.

[0089] S305. Obtain a weighted value according to the weight and sub-correction parameter corresponding to each of the at least one change item, wherein the weighted value is the correction parameter, and the weight of the temperature in the change item is the largest, and the weight of the light intensity is the smallest.

[0090] In this step, in order to obtain the final correction parameters under the combined influence of at least one variable item, a weight can be set for each variable item. The weight reflects the influence of each variable item on the final target temperature. The human body is most sensitive to temperature, and the light intensity is higher when the weather is cold. Therefore, the weight can be configured with the temperature having the largest weight, the light intensity having the smallest weight, and the humidity weight being somewhere in the middle.

[0091] The control method for the water heater provided in this embodiment obtains environmental information of the user's real-time location, determines weather changes on the user's way home, and corrects the preset target temperature, thereby adjusting the water heater to a suitable temperature. The method can intelligently identify changes in the environment on the way and scientifically adjust the heating temperature according to the changes, so that the weather on the way home and the heating temperature are effectively linked, thereby improving comfort and enhancing user experience.

[0092] Figure 4 The process of the water heater control method provided in the embodiment of the present application Figure 3 .like Figure 4 As shown, in this embodiment Figure 3 Based on the embodiment, the process of obtaining the target heating power when the interval duration is less than or equal to the heating duration is described in detail. The method includes:

[0093] S401. Obtain a candidate heating power according to the first interval duration and the target temperature, wherein the candidate heating power is greater than the preset heating power.

[0094] In this step, in order to calculate the required arithmetic heating power, the required heat is determined according to the temperature difference between the target temperature and the current water temperature. Exemplarily, based on the relationship between temperature and heat, the heat required for heating is calculated using the specific heat capacity and current weight of water. Specifically, since the volume of the water storage tank in the water heater is fixed, the current water mass can be obtained using the volume of the water storage tank and the density of water. A water level sensor can also be set in the water storage tank to obtain the actual water volume based on the measured water level. There is no limitation here.

[0095] Based on the relationship between power, time and heat, and according to the required heat and interval duration, the arithmetic heating power is obtained. The arithmetic heating power represents the actual power that the water heater can heat within the interval duration. The actual power is a relatively precise value and exists in the form of decimals, which makes it difficult for the water heater to control the power adjustment. Therefore, the power needs to be used as a candidate value for reference, and a more easily controllable integer value needs to be determined with a unified standard.

[0096] Exemplarily, the candidate heating power can be obtained by assuming that the arithmetic heating power is W2, the preset heating power is W1, the preset power step is A, and the increase coefficient is B, then W2=W1+A*B, the preset power step A represents the unit power that can be increased, and the increase coefficient B represents the power increase coefficient value. The increase coefficient calculated according to the above calculation formula may usually be a decimal, and at this time it is necessary to round the increase coefficient upward to make the increase coefficient an integer, then the rounded increase coefficient is the power parameter C, if the increase coefficient is exactly an integer value, then the increase coefficient is directly corresponded to the power parameter, and the above calculation formula becomes W=W1+A*C, at this time the power value W obtained is greater than or equal to the arithmetic heating power, and the power value W is the candidate heating power, the purpose of setting the preset power step and power parameter is to make the heating power executed by the water heater increase regularly and simplify the control of the water heater.

[0097] S402: Determine whether the candidate heating power is greater than the maximum heating power, where the maximum heating power is a power threshold for safe heating.

[0098] In this step, due to the inconsistency of the first interval time, when the user's current location is very close to home, the required interval time is very short. The heating power obtained according to this interval time will be very large, and even exceed the maximum value that the device can withstand. In addition to the safety hazard, this situation is not very feasible. Therefore, it is necessary to identify such situations. The maximum heating power within the safety range can be set as the power threshold to ensure that the power usage is within the tolerable range of the device.
