Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and particularly relates to a water heater control method. Background Art

[0002] As a common household appliance, a water heater usually operates by manually setting the temperature and the preheating time. However, this operation mode has drawbacks. For example, users usually set the same operation mode throughout the year. Since the weather varies greatly in different seasons of the year, different weather conditions result in different actual water usage demands of users. If a unified heating mode is adopted, the time for high-efficiency heating may be missed, leading to low heating efficiency. At the same time, different weather environments also affect the service performance of parts such as the inner tank and pipes of the water heater, and appropriate maintenance methods are required for maintenance. Therefore, how to enable the water heater to adjust the operation mode according to weather information to improve energy efficiency has become an important development direction in the current technical field of water heaters.

[0066] In addition, for a better illustration of the present disclosure, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present disclosure can still be implemented without certain specific details. In some instances, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail to highlight the gist of the present disclosure.

[0067] Please refer to Figure 1 , Figure 1 which is a schematic diagram of an application environment shown according to an exemplary embodiment. As Figure 1 shown, the application environment may include server 01 and terminal 02.

[0068] In an alternative embodiment, server 01 may be used to perform computational processing on the water heater control method. Specifically, server 01 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (CDN), and big data and artificial intelligence platforms.

[0069] In an alternative embodiment, terminal 02 may perform computational processing in combination with the water heater control method of server 01. Specifically, terminal 02 may include, but is not limited to, types of electronic devices such as smart phones, desktop computers, tablet computers, laptop computers, smart speakers, digital assistants, augmented reality (AR) / virtual reality (VR) devices, and smart wearable devices. Optionally, the operating systems running on the electronic devices may include, but are not limited to, Android system, IOS system, Linux system, Windows system, Unix system, etc.

[0070] For example, the target weather information is obtained by the terminal 02 and sent to the server 01. The server 01 stores energy efficiency control configuration information, which includes multiple energy efficiency control strategies and the preset weather information corresponding to each of the multiple energy efficiency control strategies. After receiving the target weather information, the server 01 performs matching processing of the energy efficiency control strategy in the energy efficiency control configuration information based on the target weather information, obtains the target energy efficiency control strategy, and sends it to the terminal 02. The target energy efficiency control strategy is the energy efficiency control strategy corresponding to the target weather information. The preset weather information corresponding to the target energy efficiency control strategy matches the target weather information. The terminal 02 controls the operation mode of the water heater based on the target energy efficiency control strategy.

[0071] In addition, it should be noted that Figure 1 The application environment shown is only one provided by the present disclosure. In actual applications, other application environments may also be included.

[0072] In the embodiments of this specification, the above-mentioned server 01 and terminal 02 can be directly or indirectly connected through wired or wireless communication methods, and the present disclosure does not limit this here.

[0073] Figure 2 It is a flowchart of a water heater control method shown according to an exemplary embodiment. The above method includes:

[0074] Step S201: Obtain the target weather information and the energy efficiency control configuration information. The energy efficiency control configuration information includes multiple energy efficiency control strategies and the preset weather information corresponding to each of the multiple energy efficiency control strategies.

[0075] In the embodiments of the present disclosure, the target weather information can be obtained through networking or through the sensor matrix of the water heater locally. Among them, the method of obtaining the target weather information through networking is configured as the preferred acquisition method.

[0076] The method of obtaining the target weather information through networking can be to configure a meteorological interface for the water heater and receive the local weather data monitored by the local meteorological bureau. The weather information obtained through networking can include current temperature information, outdoor temperature information, air pressure information, relative humidity information, sunshine intensity information, air pressure change information, temperature change information, maximum temperature statistical information, and ultraviolet information, etc., predicted precipitation probability information (such as the precipitation probability in the next 2 hours), snow depth prediction information, and weather information for a certain day in the future (such as the sunshine intensity of the next day, sunny or rainy day of the next day). The acquisition frequency of the above weather information can be to obtain the above weather information monitored by the local meteorological bureau every 1 hour.

[0077] The method of obtaining target weather information through the sensor matrix local to the water heater can be to configure and establish a basic sensor matrix locally to the water heater, including temperature and humidity sensors, barometric pressure sensors, rain-drop detection optoelectronic sensors, anemometers, etc. The weather information obtained through the local sensor matrix may include indoor temperature information, humidity information, barometric pressure information, relative humidity information, barometric pressure change information, temperature change information, and predicted precipitation probability information (such as the precipitation probability in the next 2 hours). The acquisition frequency of the above weather information can be to acquire the above weather information collected locally every 1 minute. Some weather information can be obtained by combining the weather information obtained through networking and the target weather information obtained through the sensor matrix local to the water heater, such as the indoor-outdoor temperature difference information.

[0078] Under normal circumstances, for the weather information that can be obtained through both of the above two acquisition methods, the weather information obtained through networking is preferably used. In the case where the network is blocked or the numerical gap of a certain type of weather information obtained through both of the above two acquisition methods exceeds the preset gap condition, the weather information obtained through the local sensor matrix is preferably used. For example, if the temperature difference between the real-time temperatures obtained through the above two acquisition methods continuously exceeds 2°C for 15 minutes, the weather information obtained through the local sensor matrix is preferably used until the temperature difference < 2°C, and then the weather information obtained through networking is continued to be used.

[0079] In the embodiments of the present disclosure, the multiple energy efficiency control strategies included in the energy efficiency control configuration information are energy efficiency control strategies set for different weather conditions. Different energy efficiency control strategies correspond one-to-one to different weather conditions, and the preset weather information corresponding to an energy efficiency control strategy is the weather condition to which the energy efficiency control strategy applies. The multiple energy efficiency control strategies and their respective corresponding preset weather information can be obtained through configuration.

[0080] Step S202: Perform a matching process of the energy efficiency control strategy in the energy efficiency control configuration information based on the target weather information to obtain a target energy efficiency control strategy, where the target energy efficiency control strategy is the energy efficiency control strategy corresponding to the target weather information; the preset weather information corresponding to the target energy efficiency control strategy matches the target weather information.

[0081] In the embodiments of the present disclosure, when performing the matching process of the energy efficiency control strategy in the energy efficiency control configuration information based on the target weather information, it can be achieved by performing a one-to-one matching process between the target weather information and the preset weather information corresponding to each of the multiple energy efficiency control strategies, and determining the energy efficiency control strategy corresponding to the preset weather information that matches the target weather information as the target energy efficiency control strategy.

[0082] Figure 3It is a flowchart showing a method for determining a target energy efficiency control strategy according to an exemplary embodiment. In an alternative embodiment, multiple energy efficiency control strategies include a dehumidification control strategy, a low-oxygen combustion control strategy, a moisture-proof control strategy, an energy-saving control strategy, and a cold wave prevention control strategy; as Figure 3 shown, the above-mentioned matching process of the energy efficiency control strategy in the energy efficiency control configuration information based on the target weather information to obtain the target energy efficiency control strategy includes any one of the following:

[0083] Step S301: When the precipitation probability information and temperature information included in the target weather information match the preset weather information corresponding to the dehumidification control strategy, determine that the target energy efficiency control strategy is the dehumidification control strategy.

[0084] In the embodiment of the present disclosure, the precipitation probability information is the predicted precipitation probability after a preset number of hours from the current moment, such as the precipitation probability after 1 hour or 2 hours; the temperature information is the temperature corresponding to the city where the water heater is currently located or the temperature corresponding to the street where the water heater is currently located. The preset weather information corresponding to the dehumidification control strategy includes a preset precipitation probability threshold and a temperature threshold. The matching of the precipitation probability information and temperature information included in the target weather information with the preset weather information corresponding to the dehumidification control strategy means that the precipitation probability value corresponding to the precipitation probability information is greater than the preset precipitation probability threshold, and the temperature value corresponding to the temperature information is greater than the temperature threshold.

[0085] Exemplarily, since there is more precipitation and higher temperature in summer, before precipitation occurs in summer, the probability of moisture condensation inside and around the water heater is relatively high. In order to reduce the impact of moisture condensation inside and around the water heater on the use of the water heater, a dehumidification control strategy can be set to reduce the occurrence of this phenomenon. In order to enable the water heater to automatically execute the dehumidification control strategy before precipitation occurs in summer, the relevant weather information before the occurrence of this phenomenon can be set as the preset weather information corresponding to the dehumidification control strategy, so as to trigger the execution of the dehumidification control strategy when the target weather information matches the preset weather information corresponding to the dehumidification control strategy. For summer, when the precipitation probability > 60% and the temperature > 25°C, it can be considered that the probability of moisture condensation inside and around the water heater is relatively high. Therefore, the preset precipitation probability threshold can be set to 60%, and the temperature threshold can be set to 25°C. When the precipitation probability corresponding to the precipitation probability information included in the target weather information is greater than 60%, and the temperature corresponding to the temperature information is greater than 25°C, the target weather information matches the preset weather information corresponding to the dehumidification control strategy, and it is determined that the target energy efficiency control strategy is the dehumidification control strategy.

[0086] Figure 4 It is a flowchart showing a method for obtaining precipitation probability information according to an exemplary embodiment. In an alternative embodiment, as Figure 4 shown, the precipitation probability information is obtained through the following steps:

[0087] Step S401: Obtain the air pressure change information and the temperature change information.

[0088] In the embodiments of the present disclosure, the air pressure change information is the air pressure change amount within the time period from the moment before a preset time duration to the current moment, denoted as ΔP; the temperature change information is the temperature change amount within the time period from the moment before a preset time duration to the current moment, denoted as ΔT. The above preset time duration can be 30 minutes. The air pressure change information is thus the air pressure change amount within the past 30 minutes, and the temperature change information is the temperature change amount within the past 30 minutes. The acquisition of the air pressure change information and the temperature change information can be obtained by connecting to the network or calculated based on the air pressure and temperature related data obtained from the sensor matrix of the water heater locally.

[0089] Step S402: When the air pressure change information meets the preset air pressure change condition and the temperature change information meets the preset temperature change condition, based on the preset precipitation probability prediction model, perform precipitation probability prediction processing on the air pressure change information and the temperature change information to obtain precipitation probability information.

[0090] In the embodiments of the present disclosure, the preset air pressure change condition is that the air pressure change amount ΔP indicated by the air pressure change information exceeds the preset air pressure parameter threshold, and the preset temperature change condition is that the second derivative of the temperature change amount ΔT indicated by the temperature change information with respect to time exceeds the preset temperature parameter threshold. The preset precipitation probability prediction model can be a mathematical calculation model configured locally in the water heater, such as the sigmoid function. In the case of being connected to the network, the preset precipitation probability prediction model can also be a trained deep learning model. When the preset precipitation probability prediction model is a mathematical calculation model, based on the preset precipitation probability prediction model (locally in the water heater), performing precipitation probability prediction processing on the air pressure change information and the temperature change information to obtain the precipitation probability information can be calculated by the following formula (1):

[0091] rain_prob = sigmoid(k T *d*(ΔT) / dt* + k P *ΔP) (1)

[0092] In formula (1), rain_prob is the precipitation probability information, sigmoid represents the calculation of the sigmoid function (a mathematical calculation model), ΔT is the temperature change amount, d*(ΔT) / dt* represents the second derivative of the temperature change amount ΔT with respect to time t, ΔP is the air pressure change amount, k T is the temperature weight, k T can take 0.8, k P is the air pressure weight, k P can take 0.5. Among them, k T and kP Its value can be dynamically adjusted according to the local climate through a lightweight neural network: Long Short-Term Memory (LSTM).

[0093] Step S403: When the air pressure change information does not meet the preset air pressure change condition or the temperature change information does not meet the preset temperature change condition, determine the precipitation probability information according to the rain sensing data corresponding to the rain detection optoelectronic sensor.

[0094] In the embodiments of the present disclosure, the rain detection optoelectronic sensor can perform optoelectronic detection on possible raindrops in the air to determine whether there are raindrops in the air, and then determine whether it is raining. If raindrops are detected, it is determined that it is already raining, and the precipitation probability information rain_prob = 1; if no raindrops are detected, it is determined that it is not raining, and the precipitation probability information rain_prob = 0.

[0095] Based on the above, the embodiments of the present disclosure perform precipitation probability prediction processing on the air pressure change information and the temperature change information to obtain the precipitation probability information, and can use the air pressure change situation and the temperature change situation to complete the prediction of the precipitation probability locally in the water heater; by determining the precipitation probability information according to the rain sensing data corresponding to the rain detection optoelectronic sensor, it is possible to directly determine whether there are raindrops based on the rain sensing data configured locally in the water heater, so as to obtain the precipitation probability information.

[0096] Step S302: When the snow depth prediction information included in the target weather information matches the preset weather information corresponding to the low-oxygen combustion control strategy, determine that the target energy efficiency control strategy is the low-oxygen combustion control strategy.

[0097] In the embodiments of the present disclosure, the snow depth prediction information is the snow depth value predicted for the snow depth in the current city where the water heater is located under snowy weather. The preset weather information corresponding to the low-oxygen combustion control strategy includes a preset snow depth threshold. The matching of the snow depth prediction information included in the target weather information and the preset weather information corresponding to the low-oxygen combustion control strategy means that the snow depth value corresponding to the snow depth prediction information is greater than the preset snow depth threshold.

[0098] Exemplarily, since the temperature is low during winter snowfall, the fuel consumption required for the gas water heater to produce hot water significantly increases. To reduce the fuel consumption during heavy snowfall weather, a low-oxygen combustion control strategy can be set up to reduce fuel consumption. In order to enable the water heater to automatically execute the low-oxygen combustion control strategy during heavy snowfall in winter, the relevant weather information when this phenomenon occurs can be set as the preset weather information corresponding to the low-oxygen combustion control strategy, so as to trigger the execution of the low-oxygen combustion control strategy when the target weather information matches the preset weather information corresponding to the low-oxygen combustion control strategy. Since the thicker the snow cover, the lower the temperature, when the snow cover thickness > 15 cm, it can be considered that the fuel consumption of the water heater is excessive. Therefore, the preset snow cover thickness threshold can be set to 15 cm. When the predicted snow cover thickness corresponding to the snow cover thickness prediction information included in the target weather information is greater than 15 cm, the target weather information matches the preset weather information corresponding to the low-oxygen combustion control strategy, and the target energy efficiency control strategy is determined to be the low-oxygen combustion control strategy.

[0099] Step S303: When the indoor-outdoor temperature difference information and relative humidity information included in the target weather information match the preset weather information corresponding to the moisture-proof control strategy, determine that the target energy efficiency control strategy is the moisture-proof control strategy.

[0100] In the embodiments of the present disclosure, the indoor-outdoor temperature difference information is the difference between the temperature corresponding to the city where the water heater is currently located and the temperature corresponding to the room where the water heater is currently located; the relative humidity information is the relative humidity value corresponding to the city where the water heater is currently located. The preset weather information corresponding to the moisture-proof control strategy includes a preset indoor-outdoor temperature difference threshold and a preset relative humidity threshold. The fact that the indoor-outdoor temperature difference information and relative humidity information included in the target weather information match the preset weather information corresponding to the moisture-proof control strategy means that the indoor-outdoor temperature difference value corresponding to the indoor-outdoor temperature difference information is greater than the preset indoor-outdoor temperature difference threshold, and the relative humidity value corresponding to the relative humidity information is greater than the preset relative humidity threshold.

[0101] Exemplarily, due to frequent precipitation and a relatively high temperature difference between indoor and outdoor during humid seasons such as the period of returning southward of warm air masses and the plum rain season, the difference between the perceived temperature and the actual temperature is obvious during humid seasons. Condensate water appears on the water heater pipe wall for a long time, leading to the growth of microorganisms. In order to reduce the obvious difference in perceived temperature during water use and the impact of the growth of microorganisms on the use of the water heater, a moisture-proof control strategy can be set to reduce the occurrence probability of the above phenomena. In order to enable the water heater to automatically execute the moisture-proof control strategy during humid seasons, the relevant weather information when the above phenomena occur can be set as the preset weather information corresponding to the moisture-proof control strategy, so as to trigger the execution of the moisture-proof control strategy when the target weather information matches the preset weather information corresponding to the moisture-proof control strategy. For humid seasons, when the temperature difference between indoor and outdoor > 8°C and the relative humidity > 95%, it can be considered that the probability of an obvious difference in perceived temperature during water use and the growth of microorganisms is relatively high. Therefore, the preset temperature difference threshold between indoor and outdoor can be set to 8°C, and the preset relative humidity threshold can be set to 95%. When the temperature difference between indoor and outdoor corresponding to the temperature difference information included in the target weather information is greater than 8°C, and the relative humidity corresponding to the relative humidity information is greater than 95%, the target weather information matches the preset weather information corresponding to the moisture-proof control strategy, and the target energy efficiency control strategy is determined to be the moisture-proof control strategy.

[0102] Step S304: When the maximum temperature statistical information and the ultraviolet information included in the target weather information match the preset weather information corresponding to the energy-saving control strategy, determine that the target energy efficiency control strategy is the energy-saving control strategy.

[0103] In the embodiments of the present disclosure, the maximum temperature statistical information is the daily maximum temperature values of consecutive multiple days in the city where the water heater is currently located; the ultraviolet information is the ultraviolet value corresponding to the city where the water heater is currently located. The preset weather information corresponding to the energy-saving control strategy includes a preset maximum temperature threshold corresponding to the daily maximum temperature for a preset number of consecutive days and a preset ultraviolet threshold. The matching of the maximum temperature statistical information and the ultraviolet information included in the target weather information with the preset weather information corresponding to the energy-saving control strategy means that the number of consecutive days corresponding to the maximum temperature statistical information is greater than the preset number of days, the daily maximum temperature values of the consecutive multiple days are greater than the preset maximum temperature threshold, and the ultraviolet value corresponding to the ultraviolet information is greater than the preset ultraviolet threshold.

[0104] Exemplarily, due to the high temperature and strong ultraviolet rays during the dog days and other hot weather, the solar energy is strong during hot weather, the electricity consumption during the day is high, and the electricity bill is high. In order to reduce the electricity consumption during hot weather, make full use of solar energy, and at the same time ensure the use effect of the water heater, an energy-saving control strategy can be set to achieve the above purpose. In order to enable the water heater to automatically execute the energy-saving control strategy during hot weather, the relevant weather information when the above climate phenomenon appears can be set as the preset weather information corresponding to the energy-saving control strategy, so as to trigger the execution of the energy-saving control strategy when the target weather information matches the preset weather information corresponding to the energy-saving control strategy. For hot weather, when the temperature > 35°C and the ultraviolet index > 8 for three consecutive days, it can be considered that the electricity consumption during the day is high, the electricity bill is high, and the solar energy is strong and can be fully utilized. Therefore, the preset number of days can be set to 3 days, the preset maximum temperature threshold can be set to 35°C, and the preset ultraviolet threshold can be set to 8. When the daily maximum temperature values indicated by the maximum temperature statistical information included in the target weather information satisfy that the temperature is greater than 35°C for three consecutive days and the ultraviolet index corresponding to the ultraviolet information is greater than 8, the target weather information matches the preset weather information corresponding to the energy-saving control strategy, and the target energy efficiency control strategy is determined to be the energy-saving control strategy.

[0105] Step S305: When the cooling information included in the target weather information matches the preset weather information corresponding to the cold wave prevention control strategy, determine that the target energy efficiency control strategy is the cold wave prevention control strategy.

[0106] In the embodiments of the present disclosure, the cooling information is the temperature decrease amount within one day in the city where the water heater is currently located, that is, the temperature decrease amount within 24 hours. The preset weather information corresponding to the cold wave prevention control strategy includes a preset temperature decrease amount threshold. The matching of the cooling information included in the target weather information and the preset weather information corresponding to the cold wave prevention control strategy means that the temperature decrease amount corresponding to the cooling information is greater than the preset temperature decrease amount threshold.

[0107] Exemplarily, since the temperature drops suddenly when a cold wave comes, the temperature loss of the hot water in the water heater increases. In order to reduce the heat loss caused by the sudden temperature drop, a cold wave prevention control strategy can be set to reduce the heat consumption. In order to enable the water heater to automatically execute the cold wave prevention control strategy when a cold wave comes, the relevant weather information when this phenomenon appears can be set as the preset weather information corresponding to the cold wave prevention control strategy, so as to trigger the execution of the cold wave prevention control strategy when the target weather information matches the preset weather information corresponding to the cold wave prevention control strategy. Since it can be considered that the heat consumption for directly heating the water in the water heater to the preset heating temperature is too large when the temperature decrease amount within 24 hours > 12°C, the preset temperature decrease amount threshold can be set to 12°C. When the temperature decrease amount within 24 hours corresponding to the cooling information included in the target weather information is greater than 12°C, the target weather information matches the preset weather information corresponding to the cold wave prevention control strategy, and the target energy efficiency control strategy is determined to be the cold wave prevention control strategy.

[0108] Based on the above, in the embodiments of the present disclosure, by configuring different preset weather information for different energy efficiency control strategies and matching different types of target weather information with different energy efficiency control strategies, the matched energy efficiency control strategy can be adapted to the weather conditions corresponding to the target weather information, so that the operating mode of the water heater when executing the matched energy efficiency control strategy conforms to the target weather conditions.

[0109] Step S203: Control the operating mode of the water heater based on the target energy efficiency control strategy.

[0110] In an alternative embodiment, when the target energy efficiency control strategy is a dehumidification control strategy, controlling the operating mode of the water heater based on the target energy efficiency control strategy includes:

[0111] Obtain the temperature increase information corresponding to the dehumidification control strategy, where the temperature increase information represents the temperature increase required to reduce the moisture condensation inside and around the water heater; control the water heater to perform a heating operation according to the temperature increase information.

[0112] In the embodiments of the present disclosure, the temperature increase information indicates the degree of temperature increase of the water temperature. The temperature increase information can be set by the user himself or adjusted according to the season. The temperature increase information is positively correlated with the precipitation frequency corresponding to the current season. For example, the precipitation frequency in summer is higher than that in winter, and the degree of temperature increase indicated by the temperature increase information in summer is higher than that indicated by the temperature increase information in winter. The degree of temperature increase corresponding to the temperature increase information in summer can be automatically set to 3°C, and the degree of temperature increase corresponding to the temperature increase information in winter can be automatically set to 2°C.

[0113] Controlling the water heater to perform a heating operation according to the temperature increase information can be to increase the degree of temperature increase of the water temperature indicated by the temperature increase information on the basis of the heating temperature set by the current user or the default heating temperature, to obtain a new target heating temperature. After the heating is started, the water heater performs a heating operation with the target heating temperature as the heating target until the water temperature reaches the target heating temperature and stops the heating operation, or until the dehumidification control strategy stops executing. The stop condition for the dehumidification control strategy to stop executing is that the precipitation probability information and temperature information included in the target weather information no longer match the preset weather information corresponding to the dehumidification control strategy.

[0114] Based on the above, in the embodiments of the present disclosure, by obtaining the temperature increase information corresponding to the dehumidification control strategy and controlling the water heater to automatically perform a heating operation according to the temperature increase information, it is possible to reduce the moisture condensation inside and around the water heater by automatically increasing the water temperature, reduce the influence of water vapor condensation on the use of the water heater when precipitation is about to occur, and improve the energy efficiency of the water heater in rainy weather.

[0115] In an optional embodiment, when the target energy efficiency control strategy is a low-oxygen combustion control strategy, based on the target energy efficiency control strategy, the operation mode of the water heater is controlled, including:

[0116] Obtain the target mixing ratio information corresponding to the low-oxygen combustion control strategy, where the target mixing ratio information represents the mixing ratio of air and fuel; control the water heater to perform a combustion operation according to the target mixing ratio information.

[0117] In the embodiments of the present disclosure, the mixing ratio of air and fuel represented by the target mixing ratio information is lower than the mixing ratio of air and fuel set by default for the water heater. The target mixing ratio information can be determined according to the target carbon monoxide emission reduction rate, and the target carbon monoxide emission reduction rate is the reduction rate of carbon monoxide emissions during the set low-oxygen combustion process.

[0118] Controlling the water heater to perform a combustion operation according to the target mixing ratio information may be to determine the target mixing ratio information as the control target of the air-fuel ratio. After the fuel combustion operation is started, the fuel combustion operation is performed at the mixing ratio of air and fuel indicated by the target mixing ratio information until the low-oxygen combustion control strategy stops being executed. The stop condition for the low-oxygen combustion control strategy to stop being executed is that the snow depth prediction information included in the target weather information no longer matches the preset weather information corresponding to the low-oxygen combustion control strategy.

[0119] Based on the above, in the embodiments of the present disclosure, by obtaining the target mixing ratio information corresponding to the low-oxygen combustion control strategy and controlling the water heater to automatically perform a combustion operation according to the target mixing ratio information, it is possible to control the proportion of air when the gas water heater burns fuel through the target mixing ratio information, automatically achieve low-oxygen combustion in snowy and low-temperature weather, improve fuel utilization efficiency, reduce the carbon monoxide emissions of the water heater, and improve the energy efficiency of the water heater in snowy weather.

[0120] In an optional embodiment, when the target energy efficiency control strategy is a moisture-proof control strategy, based on the target energy efficiency control strategy, the operation mode of the water heater is controlled, including:

[0121] Obtain the outlet water temperature increase information corresponding to the moisture-proof control strategy and the frequency information corresponding to the high-temperature pulse operation. The outlet water temperature increase information is used to compensate the perceived temperature, and the high-temperature pulse operation is used to kill the microorganisms on the wall condensate; control the water heater to adjust the outlet water temperature according to the outlet water temperature increase information, and control the water heater to perform the high-temperature pulse operation at the frequency indicated by the frequency information.

[0122] In the embodiments of the present disclosure, the water outlet temperature increase information indicates the degree of increase in the water outlet temperature. The temperature increase information can be set by the user himself or adjusted according to the season. The water outlet temperature increase information is positively correlated with the air humidity corresponding to the current season. For example, the air humidity in summer is higher than that in winter, and the degree of increase in the water outlet temperature indicated by the water outlet temperature increase information in summer is higher than that indicated by the water outlet temperature increase information in winter. The degree of increase in the water outlet temperature indicated by the water outlet temperature increase information in summer can be automatically set to 3°C, and the degree of increase in the water outlet temperature indicated by the water outlet temperature increase information in winter can be automatically set to 2°C.

[0123] The frequency information corresponding to the high-temperature pulse operation indicates the time interval between two adjacent high-temperature pulse operations and the duration of each high-temperature pulse operation. Exemplarily, in order to balance the killing effect and the energy efficiency of the high-temperature pulse, the frequency information corresponding to the high-temperature pulse operation starts a high-temperature pulse operation lasting for 45 seconds every 3 hours to kill the microorganisms in the condensate water on the pipe wall, and the water temperature of the high-temperature pulse operation reaches 80°C.

[0124] Controlling the water heater to perform a heating operation according to the temperature increase information can be to increase the degree of increase in the water outlet temperature indicated by the water outlet temperature increase information on the basis of the water outlet temperature set by the current user or the default water outlet temperature, so as to obtain a new target water outlet temperature. When discharging water, the water heater performs a water discharge operation with the target water outlet temperature as the water outlet temperature target; controlling the water heater to perform a high-temperature pulse operation at the frequency indicated by the frequency information can be to start a 45-second 80°C high-temperature pulse every 3 hours.

[0125] The above controls the water heater to adjust the water outlet temperature according to the water outlet temperature increase information, and controls the water heater to perform a high-temperature pulse operation at the frequency indicated by the frequency information until the moisture-proof control strategy stops executing. The stop condition for the moisture-proof control strategy to stop executing is that the indoor and outdoor temperature difference information and relative humidity information included in the target weather information no longer match the preset weather information corresponding to the moisture-proof control strategy.

[0126] Based on the above, the embodiments of the present disclosure can obtain the water outlet temperature increase information corresponding to the moisture-proof control strategy and the frequency information corresponding to the high-temperature pulse operation, control the water heater to adjust the water outlet temperature and the high-temperature pulse operation, and can automatically compensate the perceived temperature in humid seasons such as the return spring season and the plum rain season, and timely kill the microorganisms in the condensate water on the pipe wall, improve the moisture adaptability of the water heater, and improve the energy efficiency of the water heater in humid weather.

[0127] In an alternative embodiment, when the target energy efficiency control strategy is an energy-saving control strategy, based on the target energy efficiency control strategy, the operation mode of the water heater is controlled, including:

[0128] Obtain the heat storage temperature information corresponding to the energy-saving control strategy; control the water heater to heat the water temperature to the temperature indicated by the heat storage temperature information during the first target power consumption period, and the electricity price corresponding to the first target power consumption period is lower than the preset electricity price threshold.

[0129] In the embodiments of the present disclosure, the heat storage temperature indicated by the heat storage temperature information may be lower than the default heat storage temperature of the water heater. When the default heat storage temperature of the water heater is 70 °C, the heat storage temperature indicated by the heat storage temperature information may be set to 65 °C. The preset electricity price threshold may be the average of the electricity prices at different times of the day. It can be considered that the first target power consumption period is the valley electricity period when the electricity price corresponding to the first target power consumption period is lower than the preset electricity price threshold.

[0130] Controlling the water heater to heat the water temperature to the temperature indicated by the heat storage temperature information during the first target power consumption period may be to perform a heat storage operation with the heat storage temperature indicated by the heat storage temperature information as the current heating target during the valley electricity period until the water temperature reaches the temperature indicated by the heat storage temperature information.

[0131] Based on the above, the embodiments of the present disclosure can realize heat storage during the valley electricity period in high-temperature weather, avoid the electricity consumption peak in high-temperature weather, utilize the natural heat preservation of the day-night temperature difference, reduce the electricity consumption cost in high-temperature weather, and improve the energy efficiency of the water heater in high-temperature weather by obtaining the heat storage temperature information corresponding to the energy-saving control strategy and controlling the water heater to heat the water temperature to the temperature indicated by the heat storage temperature information during the first target power consumption period.

[0132] In an alternative embodiment, when the target energy efficiency control strategy is an anti-cold wave control strategy, based on the target energy efficiency control strategy, the operation mode of the water heater is controlled, including:

[0133] Determine the stepped heating mode corresponding to the anti-cold wave control strategy; control the water heater to perform a heating operation in the stepped heating mode.

[0134] In the embodiments of the present disclosure, the stepped heating mode means that the control water temperature rises in a stepped form until the water temperature reaches the target heating temperature. The stepped heating mode corresponding to the anti-cold wave control strategy is the heating temperature corresponding to different stages during the heating process. At least two heating stages are included in one heating process. The heating temperature corresponding to the first heating stage is lower than the heating temperature corresponding to the second heating stage, the heating temperature corresponding to the second heating stage is lower than the heating temperature corresponding to the third heating stage, and the heating temperature corresponding to the third heating stage is the target heating temperature.

[0135] Controlling the water heater to perform heating operation in a stepped heating mode can be as follows: when the target heating temperature is 50 °C, the heating operation can first be carried out with 40 °C as the heating target of the first heating stage. After heating the water temperature to 40 °C, then 45 °C is used as the heating target of the second heating stage for heating operation. After heating the water temperature to 45 °C, finally, the target heating temperature of 50 °C is used as the heating target for heating operation to complete this heating.

[0136] Based on the above, in the embodiment of the present disclosure, by determining the stepped heating mode corresponding to the cold wave prevention control strategy and controlling the water heater to perform heating operation in the stepped heating mode, it is possible to gradually increase the water storage temperature in the water heater in cold wave weather, avoid energy waste and ineffective heating caused by heating the water to too high a temperature at one time, and improve the energy efficiency of the water heater in cold wave weather.

[0137] Figure 5 It is a flowchart showing another method for determining the target energy efficiency control strategy according to an exemplary embodiment. In an alternative embodiment, the multiple energy efficiency control strategies include a first heat storage control strategy and a second heat storage control strategy, and the heat storage temperature indicated by the second heat storage control strategy is greater than the heat storage temperature indicated by the first heat storage control strategy; as Figure 5 shown, based on the target weather information, perform matching processing of the energy efficiency control strategy in the energy efficiency control configuration information to obtain the target energy efficiency control strategy, including:

[0138] Step S501: When the target weather information includes target predicted weather information and the current power consumption period enters the second target power consumption period, match the target predicted weather information with the first heat storage control strategy and the second heat storage control strategy respectively. The target predicted weather information represents the predicted sunshine intensity corresponding to the target time period, the target time period is a certain time period after a preset time interval from the current moment, and the electricity price corresponding to the second target power consumption period is higher than the preset electricity price threshold.

[0139] In the embodiment of the present disclosure, the preset time interval can be 12 hours or 24 hours. When the preset time interval is 12 hours, the target time period is half a day later, and the predicted sunshine intensity corresponding to the target time period predicted by the target predicted weather information is the sunshine intensity half a day later. When the preset time interval is 24 hours, the target time period is one day later, that is, the next day, and the predicted sunshine intensity corresponding to the target time period predicted by the target predicted weather information is the sunshine intensity of the next day. The preset electricity price threshold can be the average value of the electricity prices at different time periods in a day. If the electricity price corresponding to the second target power consumption period is lower than the preset electricity price threshold, it can be considered that the second target power consumption period is a peak electricity price period.

[0140] When the target weather information includes target predicted weather information and the current power consumption period enters the peak electricity price period, the target predicted weather information can be matched with the first heat storage control strategy and the second heat storage control strategy respectively, which can be to match the target predicted weather information with the preset weather information corresponding to the first heat storage control strategy and the preset weather information corresponding to the second heat storage control strategy respectively.

[0141] In an exemplary embodiment, the preset weather information corresponding to the first heat storage control strategy is a first preset sunshine intensity value, the preset weather information corresponding to the second heat storage control strategy is a second preset sunshine intensity value, and the first preset sunshine intensity value is greater than the second preset sunshine intensity value. Optionally, the value of the first preset sunshine intensity value can be a sunshine intensity value representing a sunny day, and the value of the second preset sunshine intensity value can be a sunshine intensity value representing a cloudy or rainy day.

[0142] In an exemplary embodiment, the preset weather information corresponding to the first heat storage control strategy is a first preset sunshine intensity interval, the preset weather information corresponding to the second heat storage control strategy is a second preset sunshine intensity interval, any sunshine intensity value within the first preset sunshine intensity interval is greater than any sunshine intensity value within the second preset sunshine intensity interval, and the first preset sunshine intensity interval has no intersection or intersection point with the second preset sunshine intensity interval. Optionally, the first preset sunshine intensity interval can be a sunshine intensity interval representing a sunny day, and the second preset sunshine intensity interval can be a sunshine intensity interval representing a cloudy or rainy day.

[0143] Step S502: When the target predicted weather information matches the preset weather information corresponding to the first heat storage control strategy, determine that the target energy efficiency control strategy is the first heat storage control strategy.

[0144] In the embodiments of the present disclosure, when the preset weather information corresponding to the first heat storage control strategy is the first preset sunshine intensity value, the matching between the target predicted weather information and the preset weather information corresponding to the first heat storage control strategy can be that the difference between the predicted sunshine intensity corresponding to the target period of the target predicted weather information and the first preset sunshine intensity value is less than the first preset sunshine intensity threshold. At this time, it can be considered that the weather corresponding to the predicted target period of the target predicted weather information is a sunny day.

[0145] When the preset weather information corresponding to the first heat storage control strategy is the first preset sunshine intensity interval, the matching between the target predicted weather information and the preset weather information corresponding to the first heat storage control strategy can be that the sunshine intensity value corresponding to the predicted target period of the target predicted weather information falls within the first preset sunshine intensity interval. At this time, it can be considered that the weather corresponding to the predicted target period of the target predicted weather information is a sunny day.

[0146] Step S503: When the target predicted weather information matches the preset weather information corresponding to the second heat storage control strategy, determine that the target energy efficiency control strategy is the second heat storage control strategy.

[0147] In the embodiments of the present disclosure, when the preset weather information corresponding to the second heat storage control strategy is the second preset sunshine intensity value, the matching between the target predicted weather information and the preset weather information corresponding to the second heat storage control strategy may be that the difference between the predicted sunshine intensity corresponding to the target period of the target predicted weather information and the second preset sunshine intensity value is less than the second preset sunshine intensity threshold. At this time, it can be considered that the weather corresponding to the predicted target period of the target predicted weather information is a rainy or cloudy day.

[0148] When the preset weather information corresponding to the second heat storage control strategy is the second preset sunshine intensity range, the matching between the target predicted weather information and the preset weather information corresponding to the second heat storage control strategy may be that the sunshine intensity value corresponding to the predicted target period of the target predicted weather information falls within the second preset sunshine intensity range. At this time, it can be considered that the weather corresponding to the predicted target period of the target predicted weather information is a rainy or cloudy day.

[0149] Based on the above, in the embodiments of the present disclosure, by setting different heat storage control strategy configurations, the heat storage control strategy executed by the water heater can be adapted to the predicted sunshine intensity corresponding to the target period, so that the operating mode of the water heater when executing the matched heat storage control strategy conforms to the predicted sunshine intensity.

[0150] In an alternative embodiment, based on the target energy efficiency control strategy, controlling the operating mode of the water heater includes:

[0151] When the target energy efficiency control strategy is the first heat storage control strategy, obtain the heat storage temperature reduction information corresponding to the first heat storage control strategy; and control the water heater to perform heat storage operation according to the heat storage temperature reduction information.

[0152] In the embodiments of the present disclosure, the heat storage temperature reduction information indicates the temperature value by which the heat storage temperature is reduced based on the default heat storage temperature. The heat storage temperature reduction information can be set by the user or adjusted automatically according to the target predicted weather information. The heat storage temperature reduction information is positively correlated with the predicted sunshine intensity corresponding to the target predicted weather information. The higher the predicted sunshine intensity corresponding to the target predicted weather information, the greater the reduction amount of the heat storage temperature value corresponding to the heat storage temperature reduction information. Exemplarily, the heat storage temperature reduction information can be set to 10 °C to utilize solar energy for supplementary heating during the target period.

[0153] Controlling the water heater to perform heat storage operations based on the heat storage temperature reduction information may be to reduce the heat storage temperature value reduction indicated by the heat storage temperature reduction information on the basis of the currently user-set heat storage temperature or the default heat storage temperature, so as to obtain the first target heat storage temperature. After the heat storage is started, the water heater performs heat storage operations with the first target heat storage temperature as the heat storage target until the water temperature reaches the first target heat storage temperature and stops the heat storage operation, or until the first heat storage control strategy stops being executed. The stop condition for the first heat storage control strategy to stop being executed is that the target predicted weather information included in the target weather information no longer matches the preset weather information corresponding to the first heat storage control strategy.

[0154] Alternatively, in the case where the target energy efficiency control strategy is the second heat storage control strategy, obtain the heat storage temperature increase information corresponding to the second heat storage control strategy; and control the water heater to perform heat storage operations according to the heat storage temperature increase information.

[0155] In the embodiments of the present disclosure, the heat storage temperature increase information indicates the temperature value by which the heat storage temperature increases on the basis of the default heat storage temperature. The heat storage temperature increase information can be set by the user himself or adjusted according to the target predicted weather information. The heat storage temperature increase information is negatively correlated with the predicted sunshine intensity corresponding to the target predicted weather information. The lower the predicted sunshine intensity corresponding to the target predicted weather information, the greater the increase in the heat storage temperature value corresponding to the heat storage temperature reduction information. Exemplarily, the heat storage temperature increase information can be set to 15 °C for heat storage during off-peak electricity consumption periods or off-peak electricity price periods.

[0156] Controlling the water heater to perform heat storage operations according to the heat storage temperature increase information may be to increase the heat storage temperature value increase indicated by the heat storage temperature reduction information on the basis of the currently user-set heat storage temperature or the default heat storage temperature, so as to obtain the second target heat storage temperature. During off-peak electricity consumption periods or off-peak electricity price periods, and after the heat storage is started, the water heater performs heat storage operations with the second target heat storage temperature as the heat storage target until the water temperature reaches the second target heat storage temperature and stops the heat storage operation, or until the second heat storage control strategy stops being executed. The stop condition for the second heat storage control strategy to stop being executed is that the target predicted weather information included in the target weather information no longer matches the preset weather information corresponding to the second heat storage control strategy.

[0157] Based on the above, in the embodiments of the present disclosure, by obtaining the heat storage temperature reduction information corresponding to the first heat storage control strategy and controlling the water heater to perform heat storage operations according to the heat storage temperature reduction information, when the predicted sunlight intensity is high, the heat storage temperature can be automatically reduced, the power consumption during peak electricity prices can be reduced, so as to be heated by solar energy and reduce the energy consumption of heat storage; by obtaining the heat storage temperature increase information corresponding to the second heat storage control strategy and controlling the water heater to perform heat storage operations according to the heat storage temperature increase information, when the predicted sunlight intensity is low and it is inconvenient to store heat by solar heat, the heat storage temperature can be automatically increased during valley electricity hours to reduce the heat storage cost.

[0158] In an alternative embodiment, if the target weather information does not match any of the above-mentioned multiple energy efficiency control strategies, the water heater is controlled to operate in a default operation mode, and the default operation mode can be an operation mode set by the user or the original operation mode of the water heater.
