[0075] The water input into the water supply device can be tap water or purified water.

[0076] The water inlet module 800 is connected to one end of the first heat exchange tube of the heat exchange module 300 through a pipeline.

Through the contact between the second heat exchange tube and the first heat exchange tube, the heat energy carried by the flowing medium in the second heat exchange tube is transferred to the water in the first heat exchange tube through the tube wall of the second heat exchange tube and the tube wall of the first heat exchange tube, so that the water in the first heat exchange tube is heated, thereby realizing heating of the water in the first heat exchange tube by heat exchange.

[0084] The temperature detector 24 is used to detect the temperature of water entering the water outlet module 200.

[0090] The control module 600 is electrically connected to the faucet control valve 16, the temperature detector 24 and the faucet 25. The faucet control valve 16 is a one-way valve or a two-way valve, which is used to prevent water outside the faucet 25 from entering the water outlet module 200, thereby preventing water outside the faucet 25 from contaminating the water supply device.

[0091] See also Figure 4 and Figure 5 In one embodiment, the water supply device with heat storage function further includes: a waste discharge module, the waste discharge module includes: a waste discharge control valve 17, a drainage pump 71 and a waste discharge pipe 72, and the control module 600 includes: the waste discharge control valve 17 and the drainage pump 71;

[0096] When the reflux assembly uses a compressible water bag, the control module 600 is electrically connected to the compressible water bag, and the compressible water bag is connected to one end of the faucet control valve 16. The waste discharge module discharges unnecessary water in the water path, so that the water outlet module 200 always discharges water that meets the requirements.

[0097] The exhaust control valve 17 adopts a three-way valve.

[0098] The airflow control valve adopts a one-way valve, so that gas can only enter the airflow control valve and the air inlet from the external environment, and then enter the water outlet module 200; gas or water cannot enter the external environment from the water outlet module 200 through the air inlet and the airflow control valve.

[0099] A compressible water bladder is a container that can be folded or compressed, usually to store water.

[0103] The control module 600 is electrically connected to the heating subunit. The heat storage subunit stores the flowing medium containing heat energy, thereby storing a certain amount of heat energy in advance, effectively solving the problem of insufficient supply during peak water consumption in the instant heating mode, and ensuring a stable and sufficient supply of hot water even when a large amount of water demand occurs.

[0104] It can be understood that the heating tank 41 of the heating and heat storage module 400 includes: a heating subunit and a heat storage subunit.

[0105] The heat storage subunit uses a container that can hold the flow medium, and the flow medium is stored in the container cavity. The heat storage subunit is provided with a drain port and a reflux port. The flow medium in the reflux port of the heat storage subunit is output from the drain port of the heat storage subunit to one end of the second heat exchange tube of the heat exchange module 300, and then enters the reflux port of the heat storage subunit through the other end of the second heat exchange tube of the heat exchange module 300, and then enters the heat storage subunit.

[0106] The heating subunit is a component with a heating function.

[0107] It is understandable that the heating subunit can be located outside the heat storage subunit, and the heating subunit heats the flowing medium in the accommodating chamber through the heat storage subunit. The heating subunit can also be partially located in the accommodating chamber, and the heating subunit heats the flowing medium in the accommodating chamber by directly contacting the flowing medium in the accommodating chamber.

[0108] In one embodiment, the heat storage subunit is provided with an exhaust hole 42, and the exhaust hole 42 is connected to the water outlet module 200;

[0114] In one embodiment, the flow medium in the heating and heat storage module 400 is water; when the water outlet module 200 does not drain water, the instant heating module 500 is also used to heat the water input into the instant heating module 500 and then transport it to the heating and heat storage module 400. When the water outlet module 200 does not drain water, the instant heating module 500 stores heat energy in the heating and heat storage module 400, which is conducive to improving the efficiency of storing heat energy.

[0115] It can be understood that, in this embodiment, the instant heating module 500 further includes: a first instant heating reflux valve. The first instant heating reflux valve adopts a one-way valve. The water outlet of the instant heating module 500 is connected to the heating and heat storage module 400 through the first instant heating reflux valve, that is, when the first instant heating reflux valve is turned on, the water output from the water outlet of the instant heating module 500 (the water heated by the instant heating module 500) enters the heating and heat storage module 400, thereby realizing the input of water for storing thermal energy into the heating and heat storage module 400. The first instant heating reflux valve adopts a one-way valve, so that the water output from the water outlet of the instant heating module 500 can enter the heating and heat storage module 400, while the water in the heating and heat storage module 400 cannot enter the instant heating module 500 through the water outlet of the instant heating module 500.

[0117] Optionally, the instant heating module 500 further includes an instant heating input pump. The control module 600 is connected to the instant heating input pump by telecommunication. The instant heating input pump is a water pump. The instant heating input pump is used to pump water from the heating and heat storage module 400 to the water inlet end of the instant heating module 500.

[0118] Optionally, the heating and heat storage module 400 further includes: a second instant heating reflux valve, and the control module 600 is electrically connected to the second instant heating reflux valve. The second instant heating reflux valve is connected between the water outlet of the first pumping component 43 and the water inlet of the instant heating module 500, or the second instant heating reflux valve is connected between the water inlet of the first pumping component 43 and the heating and heat storage module 400. When the second instant heating reflux valve is turned on, the water in the heating and heat storage module 400 is pumped to the water inlet of the instant heating module 500 by means of the first pumping component 43, thereby forming a part of the circulating hot water storage circuit.

[0119] In one embodiment, the water outlet module 200 is further used to discharge water based on the instant heating module 500, the heat exchange module 300 and the water inlet module 800, or to discharge water based on the instant heating module 500 and the heat exchange module 300.

The water outlet module 200 replenishes water to the heating and heat storage module 400 through the water replenishment module, thereby providing a basis for heat exchange.

[0125] When the water outlet module 200 does not include the tap control valve 16, the water path from the water inlet 80, the second control valve 12, the fifth control valve 15, the fourth control valve 14 to the tap 25 is used as a normal temperature water path. When the water outlet module 200 also includes the tap control valve 16, the water path from the water inlet 80, the second control valve 12, the fifth control valve 15, the fourth control valve 14, the tap control valve 16 to the tap 25 is used as a normal temperature water path.

[0126] The water path from the water inlet 80, the first control valve 11, the first heat exchange tube of the heat exchanger 32, the heater 51, one end of the fourth control valve 14, and the fourth control valve 14 to the faucet 25 is used as a hot water path.

[0127] The first waste water discharge path is from the faucet control valve 16, the waste discharge control valve 17, the drain pump 71 and the waste water discharge pipe 72, and the second waste water discharge path is from the heating hot tank 41, the waste discharge control valve 17, the drain pump 71 to the waste water discharge pipe 72.

[0128] The water path from the faucet control valve 16, the waste control valve 17 to the heating tank 41 is used as a hot water return water path.

[0129] It can be understood that the drainage pump 71 is connected to the first connection port of the heating hot tank 41 through a pipeline, and the other end of the second heat exchange pipe of the heat exchanger 32 is connected to the second connection port of the heating hot tank 41. The first connection port (on the heating hot tank 41) and the second connection port (on the heating hot tank 41) can be shared or independently provided.

[0130] Optionally, the control module 600 includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, and the processor implements the steps of the water supply device sterilization control method of the present application when executing the computer program. The method includes: obtaining a sterilization start signal; determining a target sterilization scheme according to the sterilization start signal; and controlling the water supply device to sterilize the waterway according to the target sterilization scheme. The present application obtains the target sterilization scheme in real time based on the sterilization start signal, thereby achieving flexibility and pertinence of the sterilization method, and controls the water supply device to sterilize the waterway according to the target sterilization scheme, thereby achieving the most ideal sterilization effect through a flexible and pertinent target sterilization scheme. Therefore, the present application solves the technical problem that various harmful microorganisms such as bacteria and viruses are easily bred inside the water supply device during the long-term use of the water supply device, and these microorganisms may be spread along with the use of the water discharged from the water supply device.

[0131] Optionally, the water supply device sterilization control method of the present application is implemented by a smart device, and the smart device is connected to the water supply device for communication. The smart device is used to: obtain a sterilization start signal; determine a target sterilization scheme according to the sterilization start signal; and control the water supply device to sterilize the waterway according to the target sterilization scheme.

[0132] Smart devices include, but are not limited to: various personal computers, laptops, smart phones, tablets, portable wearable devices, smart gateways, and servers.

[0133] The present invention is described in detail below through specific embodiments.

[0134] See also Figure 2 As shown, Figure 2 A flow chart of a method for controlling the sterilization of a water supply device provided in an embodiment of the present invention is provided. The method is used to control a water supply device. The method includes:

[0135] S1: Obtain sterilization start signal;

[0136] The sterilization start signal is a signal for starting the sterilization of the water path of the water supply device.

[0137] The water path of the water supply device is the pipes and components through which the water in the water supply device flows (for example, the heating tank, the first pipe of the heat exchanger, the second pipe of the heat exchanger).

[0138] Specifically, the user can trigger the sterilization start signal through the button on the water supply device, the user can also input the sterilization start signal through the touch screen on the water supply device, the user can also input the sterilization start signal through the client connected to the water supply device for communication, and the user can also send the sterilization start signal to the server through a third-party application, and the server will send the sterilization start signal to the program file that implements this application.

[0139] It is understandable that the program file implementing the present application may also actively generate a sterilization start signal according to preset conditions.

[0140] The client may include but is not limited to: various personal computers, laptops, smart phones, tablet computers, portable wearable devices.

[0141] The server may be a server.

[0142] S2: Determine a target sterilization scheme according to the sterilization start signal;

[0143] Specifically, when the sterilization start signal is obtained, the target sterilization scheme can be obtained from a preset storage space, or the target sterilization scheme can be written into a program file that implements the water supply device sterilization control method of the present application. The target sterilization scheme can also be generated according to the information carried by the sterilization start signal using a preset scheme generation method.

[0144] The target sterilization plan describes the scope of the waterways that need to be sterilized and the specific control data for sterilization.

[0145] S3: According to the target sterilization scheme, control the water supply device to sterilize the water channel.

[0146] Specifically, according to the target sterilization scheme, all or part of the water channels of the water supply device are controlled to be sterilized.

[0147] Optionally, according to the target sterilization scheme, at least one of the water inlet module 800, the heat exchange module 300, the heating and heat storage module 400, the instant heating module 500, and the water outlet module 200 is controlled to perform waterway sterilization.

[0148] For water sterilization, high temperature water can be used for sterilization. For some special bacteria, special sterilizers are required for targeted sterilization.

[0149] It is understandable that the high-temperature water used for water sterilization in the present application can be generated by heating water in the water supply device itself, or can be input into the water supply device through the water inlet of the water supply device.

[0150] This embodiment obtains the target sterilization scheme in real time according to the sterilization start signal, achieves flexibility and pertinence of the sterilization method, and controls the water supply device to sterilize the waterway according to the target sterilization scheme, thereby achieving the most ideal sterilization effect through the flexible and pertinent target sterilization scheme. Therefore, the present application solves the technical problem of the prior art that various harmful microorganisms such as bacteria and viruses are easily bred inside the water supply device during long-term use, and these microorganisms may be spread along with the use of the water discharged by the water supply device.

[0151] In one embodiment, the step of obtaining a sterilization start signal includes:

[0152] S11: generating an evaluation signal based on the evaluation time interval data, wherein the durations of the evaluation time intervals in the evaluation time interval data are sorted from large to small;

[0153] Optionally, the evaluation time interval data includes: a combination of a start time and a natural time interval. The natural time interval combination includes one or more natural time intervals. The natural time interval is an interval whose duration is calculated in natural time. A start time is obtained by adding a natural time interval to the start time.

[0154] Optionally, the evaluation time interval data includes: a combination of a start time and a usage time interval. The usage time interval combination includes one or more usage time intervals. The usage time interval is an interval that calculates the duration of the water supply device based on its usage time. A start time is obtained by adding a usage time interval to the start time.

[0155] Specifically, when each start time corresponding to the evaluation time interval data is reached, an evaluation signal is generated once.

[0156] S12: Responding to the evaluation signal, obtaining data to be evaluated;

[0157] The data to be evaluated includes at least one of phase water use data, historical cleaning data, water source access data and phase environmental data.

[0158] The stage environmental data include: stage environmental temperature data, stage environmental humidity data and stage input water quality data.

[0159] The stage water use data is the water use data of the water supply device after the last sterilization of the water supply device. The stage water use data describes the associated data corresponding to the water use time, water use amount and water use temperature.

[0160] Historical cleaning data is the data of historical cleaning of water supply devices. Historical cleaning data describes the cleaning time, relevant parameters during the cleaning process (such as water temperature, water pressure, etc.), and the detection data of the water supply device after cleaning (such as bacterial residue, water quality indicators, etc.).

[0161] The stage ambient temperature data refers to the temperature data of the environment in the space where the water supply device is located after the water supply device was last sterilized. When the ambient temperature is at a higher level, it will provide more suitable conditions for the growth and reproduction of bacteria. The activity of bacteria will increase, and it is easy for them to breed and spread in large numbers in the water supply device, accelerating the speed and range of bacterial growth, which may cause the water supply device to have more serious bacterial contamination problems in a shorter period of time; when the ambient temperature is lower, the growth of bacteria will be inhibited to a certain extent, the reproduction speed will be relatively slow, and the water supply device will have relatively mild bacterial growth. In short, changes in ambient temperature data will directly affect the possibility and degree of bacterial growth in the water supply device, and it is a key factor that cannot be ignored.

[0162] The stage environmental humidity data refers to the humidity data of the environment in the space where the water supply device is located after the water supply device was sterilized last time. When the humidity is high, the moisture content in the entire space is high, which creates favorable conditions for the growth of bacteria. A high humidity environment easily forms a layer of water vapor on the surface and around the water supply device. Bacteria are more likely to survive and reproduce in this humid atmosphere. They can attach to the water supply device with the help of water vapor and spread rapidly, increasing the risk and degree of bacterial growth. When the humidity is low, the environment is relatively dry, the survival and spread of bacteria will be limited to a certain extent, the possibility of bacteria breeding in the water supply device will be greatly reduced, and the water supply device can be kept relatively clean to a certain extent. Therefore, the level of environmental humidity data has a significant impact on the breeding of bacteria in the water supply device.

[0163] The water quality data input at the stage refers to the water quality data of the water input into the water supply device after the water supply device was sterilized last time. If the water quality data shows that the water quality itself is poor and contains more impurities, organic matter or microorganisms, etc., then this may increase the risk of bacteria breeding in the water dispenser. Poor water quality may carry more bacteria into the water supply device, which is easier to reproduce and grow under suitable temperature and environment.

[0164] The water source access data is the description data of the connectivity relationship between the external water source and the water inlet of the water inlet module.

[0165] Specifically, after the evaluation signal is obtained, the data to be evaluated may be obtained from a preset storage space, and the data to be evaluated may also be obtained from a third-party application.

[0166] S13: performing bacterial data prediction according to the data to be evaluated to obtain a bacterial data prediction result;

[0167] Optionally, a regular expression is used to calculate the index value of each indicator based on the water usage data of the stage, the historical cleaning data, the water source access data and the environmental data of the stage, and each index value is input into a preset bacterial data calculation formula to calculate the bacterial data, and the calculated bacterial data is used as the bacterial data prediction result.

[0168] The preset bacterial data calculation formula is a formula obtained by fitting based on historical data in advance. The specific fitting method includes but is not limited to linear fitting.

[0169] Optionally, the stage water usage data, the historical cleaning data, the water source access data and the stage environmental data are input into a pre-trained trend prediction model to perform bacterial data prediction to obtain a bacterial data prediction result.

[0170] The pre-trained trend prediction model is a model that predicts future trends based on the pre-trained time series model. The model structure and model training method of the trend prediction model can be selected from the existing technology and will not be described here. The time series model can use moving average, autoregressive moving average (ARMA), autoregressive integrated moving average (ARIMA), etc.

[0171] S14: determining whether sterilization is required based on the bacteria data prediction result and the preset sterilization start condition, and obtaining a determination result;

[0172] Specifically, a regular expression is used to determine whether the bacteria data prediction result meets the requirements of the preset sterilization start conditions; if the bacteria data prediction result meets the requirements of the preset sterilization start conditions, it means that sterilization is required, and the judgment result is determined to be yes; if the bacteria data prediction result does not meet the requirements of the preset sterilization start conditions, it means that sterilization is not required, and the judgment result is determined to be no.

[0173] S15: If the judgment result is yes, generating the sterilization start signal according to the bacteria data prediction result;

[0174] Specifically, if the judgment result is yes, it means that sterilization is required. Therefore, the sterilization start signal is generated according to the bacteria data prediction result to start sterilization.

[0175] The step of controlling the water supply device to sterilize the waterway according to the target sterilization scheme includes:

[0176] S31: According to the target sterilization scheme, controlling the water supply device to sterilize the water channel, and obtaining a sterilization completion signal;

[0177] S32: In response to the sterilization completion signal, the current time is used as the start time of the evaluation time interval data.

[0178] Specifically, receiving the sterilization completion signal means that the sterilization start signal has been completed and a new evaluation cycle needs to be restarted for monitoring. Therefore, the current time is used as the start time of the evaluation time interval data to reset the evaluation cycle and start the next round of monitoring.

[0179] The duration of the evaluation time intervals in the evaluation time interval data described in this embodiment is sorted from large to small, so that the longer the time from the most recent sterilization in history, the shorter the evaluation interval, so that sterilization can be started in time when sterilization is needed; when the bacterial data prediction result meets the requirements of the preset sterilization start conditions, a sterilization start signal is generated to start sterilization, so as to avoid frequent sterilization leading to waste of resources and affecting the user's water use; when the sterilization completion signal is received, the current time is used as the start time of the evaluation time interval data to reset the evaluation cycle and start the next round of monitoring, so as to start a new evaluation cycle after each sterilization is completed, which helps to promptly discover possible subsequent problems or changes, and will not generate evaluation signals too frequently, saving computing resources.

[0180] In one embodiment, the step of determining a target sterilization scheme according to the sterilization start signal includes:

[0181] S21: Responding to the sterilization start signal, obtaining user sterilization preference data;

[0182] The user sterilization preference data describes the user's preference for sterilization. The user sterilization preference data includes sterilization method preference, sterilization intensity preference, sterilization time preference and sterilization frequency preference. The sterilization method preference describes the preference for different sterilization methods such as ultraviolet sterilization, chemical sterilization, and high temperature sterilization. The sterilization intensity preference describes the preference for strong sterilization effect or milder sterilization degree. The sterilization time preference describes the preference for the duration of each sterilization. The sterilization frequency preference describes the preference for how often sterilization is performed.

[0183] Specifically, when the sterilization start signal is obtained, in response to the sterilization start signal, the user sterilization preference data can be obtained from a preset storage space, or from a third-party application, or can be the user sterilization preference data input by the user.

[0184] S22: Determine sterilization requirement information according to the bacteria data prediction result in the sterilization start signal;

[0185] The sterilization demand information may specifically include: what kind of bacteria to sterilize, such as common Escherichia coli, Staphylococcus aureus, etc.; the required degree of sterilization effect, whether to completely eliminate the bacteria or reduce their number; the requirements for the sterilization method, whether to use physical sterilization such as ultraviolet rays, high temperature, etc., or chemical sterilization methods; the expected sterilization time, how long it takes to complete the effective sterilization process; and the scope of application of sterilization, whether it is a specific surface of an object, a certain spatial area or the entire environment; it may also include considerations on whether there will be other impacts during the sterilization process, such as odor, whether there is potential damage to surrounding objects or the human body, and other information.

[0186] Optionally, based on the bacterial data prediction result in the sterilization start signal, a table lookup method is used to determine the sterilization requirement information.

[0187] Optionally, the bacterial data prediction result in the sterilization start signal is input into a pre-trained sterilization demand model for classification prediction, the maximum probability value of each bacterium is extracted from the vector obtained by the classification prediction, and the classification category corresponding to the vector element corresponding to the extracted probability value is used as the single bacteria demand information corresponding to the bacteria corresponding to the probability value; and each single bacteria demand information is used as sterilization demand information.

[0188] The pre-trained sterilization requirement model is a pre-trained multi-classification model. The model structure and model training method of the sterilization requirement model can be selected from the existing technology and will not be described in detail here.

[0189] S23: Determine an initial sterilization plan according to the user sterilization preference data;

[0190] Optionally, according to the user sterilization preference data, a scheme identifier is determined by a table lookup method, and the sterilization scheme corresponding to the determined scheme identifier is used as the initial sterilization scheme. The scheme identifier may be data that uniquely identifies a sterilization scheme, such as a scheme name or a scheme ID.

[0191] Optionally, the user sterilization preference data is input into a pre-trained scheme prediction model for classification prediction, and the vector element with the largest probability value is extracted from the predicted vector. The classification category (that is, the scheme identifier) ​​corresponding to the extracted vector element is used as the target identifier, and the sterilization scheme corresponding to the target identifier is used as the initial sterilization scheme.

[0192] The pre-trained solution prediction model is a pre-trained multi-classification model. The model structure and model training method of the solution prediction model can be selected from the existing technology and will not be described in detail here.

[0193] S24: According to the sterilization requirement information, the initial sterilization plan is updated to obtain the target sterilization plan.

[0194] Specifically, according to the sterilization requirement information, the parameter values ​​in the initial sterilization scheme are updated, and the updated initial sterilization scheme is used as the target sterilization scheme.

[0195] This embodiment first determines the sterilization requirement information based on the bacterial data prediction results in the sterilization start signal, and then updates the initial sterilization plan determined according to the user's sterilization preference data based on the sterilization requirement information to ensure that the final target sterilization plan fully considers the user's personal preferences for sterilization methods, intensity, range, etc., and is closely combined with the accurate prediction of bacterial data. This makes the sterilization plan more personalized and targeted, and can meet the user's specific needs to the greatest extent. At the same time, due to the combination of bacterial data prediction results, the plan can more effectively deal with various bacterial situations during actual implementation, and improve the accuracy and efficiency of sterilization.

[0196] See also Figure 3 As shown, in one embodiment, after the step of controlling the water supply device to sterilize the waterway according to the target sterilization scheme, the step further includes:

[0197] S41: Obtaining sterilization effect test data;

[0198] By installing bacteria detection sensors at different locations of the waterway of the water supply device. Bacteria detection sensors include but are not limited to: biochemical sensors, optical sensors, and nanomaterial sensors.

[0199] Specifically, according to the target sterilization scheme, after controlling the water supply device to perform the step of sterilizing the water channel, a sterilization completion signal is generated, and in response to the sterilization completion signal, data detected by each bacteria detection sensor is obtained as sterilization effect detection data.

[0200] S42: judging whether a sterilization target corresponding to the user sterilization preference data is achieved according to the sterilization effect detection data;

[0201] Specifically, a regular expression is used to calculate whether the sterilization effect detection data reaches the sterilization target corresponding to the user sterilization preference data.

[0202] S43: If the target value is not reached, a supplementary sterilization scheme is determined according to the sterilization effect detection data and the target sterilization scheme;

[0203] Specifically, if it is not achieved, that is, the sterilization effect detection data does not reach the sterilization target corresponding to the user sterilization preference data, it means that supplementary sterilization is needed. According to the sterilization effect detection data, a sub-scheme is selected from the target sterilization scheme to obtain a supplementary sterilization scheme.

[0204] Optionally, the sterilization effect detection data and the target sterilization scheme are input into a pre-trained supplementary scheme prediction model for classification prediction, and the vector element with the largest value is found from the predicted vector, and the sub-scheme corresponding to the vector element is used as the supplementary sterilization scheme.

[0205] If it is achieved, that is, the sterilization effect detection data reaches the sterilization target corresponding to the user sterilization preference data, it means that no additional sterilization is needed.

[0206] S44: According to the supplementary sterilization scheme, control the water supply device to sterilize the water channel.

[0207] Specifically, according to the supplementary sterilization scheme, all or part of the water channels of the water supply device are controlled to perform supplementary sterilization.

[0208] This embodiment controls the water supply device to perform water channel sterilization for supplementary sterilization according to the supplementary sterilization scheme, thereby ensuring that the final sterilization effect meets the sterilization target corresponding to the user sterilization preference data; and determines the supplementary sterilization scheme based on the sterilization effect detection data and the target sterilization scheme, thereby improving the accuracy of the supplementary sterilization.

[0209] In one embodiment, the target sterilization scheme includes: at least one step configuration data, the step configuration data including: step information and step control data;

[0215] Wherein, the target sterilization scheme includes at least two step configuration data, and the two step configuration data include in sequence: the step control data corresponding to the sterilization step and the step control data corresponding to the flushing step.

[0216] High temperature sterilization temperature is the temperature required for sterilization. High temperature water immersion is to immerse the waterway that needs to be sterilized in high temperature water. Circulating high temperature water flushing is to use high temperature water to circulate and flush the waterway that needs to be sterilized. Single high temperature water flushing is to use high temperature water to flush the waterway that needs to be sterilized once.

[0217] High-temperature ozone water immersion is to immerse the waterway that needs to be sterilized with high-temperature water containing ozone. Circulating high-temperature ozone water flushing is to use high-temperature water containing ozone to circulate and flush the waterway that needs to be sterilized. Single high-temperature ozone water flushing is to use high-temperature water containing ozone to flush the waterway that needs to be sterilized once.

[0218] The steam sterilization step is a step of using steam sterilization. Steam sterilization is to input high-temperature steam into the water channel of the water supply device to sterilize the water channel.

[0219] The vinegar sterilization step is a step of using vinegar for sterilization. Vinegar sterilization is to use water containing vinegar to sterilize the waterway of the water supply device. The acidic components contained in vinegar have certain sterilization and disinfection capabilities, and can effectively inhibit the growth and reproduction of microorganisms such as bacteria and fungi in the waterway. This sterilization method is relatively mild and safe, and will not cause corrosive damage to the water supply device and related components. At the same time, edible vinegar is easy to obtain, low in cost, and relatively simple to operate. By mixing it with water and circulating or soaking it in the waterway, it can more comprehensively cover the entire waterway system, give full play to its sterilization effect, keep the waterway clean and sanitary, thereby ensuring that the water supply device provides people with safe and healthy water in a long-term and stable manner.

[0220] This embodiment sets different step control data according to different step information, which is conducive to targeted sterilization; through the combination of different step information, refined and intelligent control of the sterilization process of the water supply device is achieved. By setting different step control data according to different step information, it can accurately adapt to various sterilization needs and scenarios, greatly improving the targetedness and effectiveness of sterilization.

[0221] In one embodiment, the water supply device includes: a water inlet module, a heat exchange module, a heating and heat storage module, an instant heating module, a water outlet module and a waste discharge module;

[0222] The heating and heat storage module is used to heat and then store the flowing medium entering the heating and heat storage module;

[0223] The heat exchange module is used to perform heat exchange on the water input into the heat exchange module by the water inlet module based on the flowing medium circulated into the heat exchange module by the heating and heat storage module;

[0224] The instant heating module is used to heat the water after the heat exchange of the heat exchange module;

[0225] The water outlet module is used to discharge water based on the instant heating module, or to discharge water based on the instant heating module and the water inlet module;

[0226] The waste discharge module is used to discharge the waste water after sterilization of the water supply device;

[0227] The waste discharge module is in communication with the heat exchange module, the heating and heat storage module, the instant heating module, and the water outlet module;

[0228] The step of controlling the water supply device to sterilize the waterway according to the target sterilization scheme includes:

[0229] According to the target sterilization scheme, the water supply device is controlled to perform water channel sterilization, wherein during the water channel sterilization process, wastewater generated by the water channel sterilization is discharged from the water supply device through the waste discharge module.

[0230] By setting the heating and heat storage module 400, this embodiment can store a certain amount of hot water in advance, effectively solving the problem of insufficient supply in the instant heating mode during the peak water use period, and ensuring that there is a stable and sufficient supply of hot water when a large amount of water demand is concentrated. The heat exchange module 300 uses the flowing medium circulated by the heating and heat storage module 400 for heat exchange, which improves the energy utilization efficiency and reduces energy loss. The setting of the instant heating module 500 can further heat quickly when needed, making the outlet water temperature more flexible and adjustable. The water outlet module 200 can choose to drain water based on the instant heating module 500 alone or in combination with the water inlet module 800 according to different situations, meeting the diverse water needs. The electrical connection of the control module 600 realizes the precise control and coordinated operation of each module, ensures the stable and efficient operation of the entire water supply device system, greatly improves the user's water experience, and makes the hot water supply more reliable and convenient. In the process of waterway sterilization, the wastewater generated by the waterway sterilization is discharged from the water supply device through the waste discharge module, so that the wastewater generated by the sterilization can be discharged from the water supply device, which is conducive to the collection of wastewater and avoids user misuse.

[0231] In one embodiment, the water outlet module comprises: a faucet control valve and a faucet;

[0232] One end of the faucet control valve is connected to the instant heating module, or one end of the faucet control valve is connected to the instant heating module and the water inlet module;

[0233] The other end of the faucet control valve is connected to the faucet;

[0234] The step of controlling the water supply device to sterilize the waterway according to the target sterilization scheme includes:

[0235] When the faucet control valve is controlled to be disconnected, the water supply device is controlled to sterilize the water channel according to the target sterilization scheme.

[0236] In this embodiment, the faucet control valve is used to prevent waste water generated by waterway sterilization from being discharged from the faucet to the water supply device, thereby preventing users from mistakenly using waste water generated by waterway sterilization. By controlling the faucet control valve to be disconnected, the water supply device is controlled to perform waterway sterilization according to the target sterilization scheme, thereby preventing waste water after sterilization from being discharged from the faucet.
