[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] One of the core concepts of the embodiments of the present invention is that the present invention can obtain the user's biometric information; determine the target water temperature corresponding to the water dispenser based on the biometric information; determine whether the outlet water temperature of the water dispenser needs to be adjusted based on the target water temperature; if the outlet water temperature of the water dispenser needs to be adjusted, adjust the outlet water temperature to the target water temperature based on the target water temperature; and control the water dispenser to discharge water when receiving the user's water outlet control instruction; the user's biometric information can be obtained to determine the corresponding target water temperature, which can meet the personalized water temperature needs of different users and improve the user experience. It can determine whether the outlet water temperature of the water dispenser needs to be adjusted based on the target water temperature, and only adjust it when the current water temperature is inconsistent with the target water temperature, thereby avoiding the water dispenser from continuously heating or cooling the water, especially when multiple people use it and have different water temperature requirements, which can effectively reduce energy waste.

[0052] like Figure 1 , showing the steps of a water dispenser control method provided by an embodiment of the present invention, the method may include the following steps:

[0053] Step 101, obtaining the user's biometric information.

[0054] In the embodiments of the present invention, biometric information refers to data related to physiological or behavioral characteristics that can uniquely identify an individual. Common biometric information may include fingerprints, faces, irises, etc. In the context of water dispenser control, this information may be obtained through corresponding sensors. For example, if fingerprint recognition is used, the fingerprint sensor equipped on the water dispenser will scan and record the fingerprint pattern features when the user touches the specified area; if face recognition is used, a camera installed at a suitable position on the water dispenser will capture the user's facial image and extract information such as key facial feature points, so as to obtain biometric information that can be used to subsequently identify the user's identity, thereby preparing for accurately judging the needs of different users.

[0055] Step 102: Determine the target water temperature corresponding to the water dispenser based on the biometric information.

[0056] In an embodiment of the present invention, after obtaining the user's biometric information, the system pre-stores the correspondence data between different users and their preferred water temperatures. For example, the system records that user A is accustomed to drinking 40°C warm water, and user B prefers 80°C hot water for making tea, etc. When it is recognized that the current biometric information belongs to user A, it will be determined based on this correspondence that the target water temperature corresponding to the user's use of the water dispenser this time is 40°C. If it is recognized that it is user B, the target water temperature is 80°C, thereby realizing personalized matching of the water temperature setting of each user's habits.

[0057] Step 103, judging whether it is necessary to adjust the outlet water temperature of the water dispenser according to the target water temperature;

[0058] In the embodiment of the present invention, the water dispenser itself usually has a current default water outlet temperature or a water temperature setting value after the last use. The target water temperature determined previously can be compared with the actual water outlet temperature of the water dispenser at this time. For example, the current water outlet temperature of the water dispenser is 25°C, and the target water temperature determined according to the user's biometric information is 60°C. There is a difference between the two, which means that the water temperature needs to be adjusted; but if the target water temperature happens to be 25°C, which is consistent with the target water temperature, then there is no need to adjust the water temperature, so as to determine whether to take the next step of water temperature adjustment.

[0059] Step 104: If the outlet water temperature of the water dispenser needs to be adjusted, the outlet water temperature is adjusted to the target water temperature according to the target water temperature.

[0060] In the embodiment of the present invention, when it is determined that the outlet water temperature of the water dispenser needs to be adjusted, the temperature control device inside the water dispenser will start working. If it is a traditional water dispenser using heating elements such as heating rods, the water temperature will be increased by controlling the power of the heating rods, the heating time, etc. For example, if the target water temperature is 70°C and the current water temperature is 30°C, the temperature control system will increase the power of the heating rod or extend the heating time to gradually increase the water temperature to 70°C; for water dispensers with refrigeration function, if the target water temperature is lower than the current water temperature, refrigeration components such as refrigeration compressors will be started, and the water temperature will be reduced to the target water temperature value according to the set refrigeration strategy. In this way, the outlet water temperature can be accurately adjusted to the target water temperature that meets user needs.

[0061] Step 105, when receiving a water outlet control instruction from the user, control the water dispenser to outlet water.

[0062] In the embodiment of the present invention, the user can issue water outlet control instructions in a variety of ways, such as pressing the water outlet button on the water dispenser, or clicking the corresponding water outlet operation interface button through a mobile phone APP. When the water dispenser receives such an instruction, the internal water outlet valve and other related water outlet control components will be triggered to open the corresponding water channel, so that water with the target water temperature adjusted will flow out from the water outlet of the water dispenser, making it convenient for the user to collect water for drinking or use, completing the entire control process from identifying the user to providing water outlet with a water temperature that meets their requirements.

[0063] It should be noted that the water output control instructions can also be controlled by voice. In water dispensers that support voice control function, a voice recognition module is usually built in. When the user approaches the water dispenser and speaks a specific voice command, such as "Water dispenser, water out" or "I want to get water" and other preset sentences, the voice recognition module will first process the collected voice signal. It will convert the voice sound wave signal into a digital signal, and then use the voice recognition algorithm to compare and match it with the voice command template pre-stored in the system. If it is recognized that the sentence spoken by the user meets the set water output control related instructions, the recognition result will be passed to the central controller of the water dispenser.

[0064] After the central controller receives the effective water outlet command information from the voice recognition module, it will immediately trigger the internal water outlet valve and other related water outlet control components, just like receiving instructions from conventional methods such as pressing the water outlet button, and open the water channel to allow water with adjusted target water temperature to flow out from the water outlet, which is convenient for users. The present invention uses voice control to greatly improve the convenience of operation, especially for situations where it is inconvenient to operate buttons with both hands or there is a certain distance from the water dispenser. Users only need to use simple voice calls to easily control the water outlet of the water dispenser, which brings more convenience to daily life.

[0065] The present invention discloses a water dispenser control method, which obtains biometric information of a user; determines a target water temperature corresponding to the water dispenser according to the biometric information; determines whether the outlet water temperature of the water dispenser needs to be adjusted according to the target water temperature; if the outlet water temperature of the water dispenser needs to be adjusted, adjusts the outlet water temperature to the target water temperature according to the target water temperature; and controls the water dispenser to discharge water when a water discharge control instruction of the user is received; the biometric information of the user can be obtained to determine the corresponding target water temperature, which can meet the personalized water temperature requirements of different users and improve the user experience; it can determine whether the outlet water temperature of the water dispenser needs to be adjusted according to the target water temperature, and the water temperature is adjusted only when the current water temperature is inconsistent with the target water temperature, thereby avoiding the water dispenser from continuously heating or cooling water, especially when multiple people use the water dispenser and have different water temperature requirements, which can effectively reduce energy waste.

[0066] In one embodiment of the present invention, whether the outlet water temperature of a water dispenser needs to be adjusted is determined based on a target water temperature, including: obtaining the current water temperature; determining the temperature difference between the target water temperature and the current water temperature; if the absolute value of the temperature difference is less than a preset threshold, determining that the outlet water temperature of the water dispenser does not need to be adjusted; the method also includes: if the outlet water temperature of the water dispenser does not need to be adjusted, when a water outlet control instruction from the user is received, controlling the water outlet of the water dispenser.

[0067] In an embodiment of the present invention, a water dispenser is usually equipped with a corresponding temperature sensor to obtain the current water temperature. For example, it can detect the water temperature value in real time. When the current water temperature is detected to be 25°C, this temperature data can be transmitted to the control unit of the water dispenser, providing an important reference for subsequent judgment on whether the water temperature needs to be adjusted.

[0068] After obtaining the current water temperature and determining the target water temperature based on the user's biometric information, the control unit will perform a difference calculation. For example, if the target water temperature determined in the previous step is 35°C and the current water temperature just obtained is 20°C, then the temperature difference between the two is 35-20=15°C. This difference reflects the degree of deviation between the target water temperature and the actual ambient temperature, and plays a key role in determining whether to adjust the water temperature in the future.

[0069] A specific temperature threshold is pre-set in the central controller of the water dispenser. This threshold is set based on comprehensive consideration of multiple factors such as water temperature stability and actual user experience. Assuming the preset threshold is 5°C, when the absolute value of the calculated target water temperature and the current water temperature difference is less than 5°C, such as the aforementioned difference of 15°C, this condition is not met. However, if the target water temperature is 22°C, the absolute value of the difference with the ambient temperature of 20°C is 2°C (less than 5°C). At this time, it is considered that although the current outlet water temperature of the water dispenser may be somewhat different from the target water temperature, this difference is within an acceptable range. Therefore, it is determined that there is no need to adjust the outlet water temperature of the water dispenser. This can avoid adjusting the water temperature too frequently, reduce unnecessary energy consumption and equipment loss, and at the same time, to a certain extent, ensure that the water temperature received by the user can basically meet the demand.

[0070] After the above judgment determines that the water temperature does not need to be adjusted, once the user issues a water outlet control command, whether by pressing the water outlet button on the water dispenser, using a mobile phone APP for remote operation, or issuing the command through voice control, the control unit of the water dispenser will directly respond to the command. It will drive the internal water outlet valve and other related components to open, so that water flows out of the water outlet according to the current water temperature, allowing the user to receive water smoothly, thereby completing the entire relatively simplified water outlet process. While meeting the basic needs of users, it also ensures the efficiency and convenience of operation.

[0071] In an embodiment of the present invention, it further includes: if the absolute value of the temperature difference is greater than a preset threshold, it is determined that the outlet water temperature of the water dispenser needs to be adjusted.

[0072] In an embodiment of the present invention, if the preset threshold is 5 degrees Celsius, the determined target water temperature is 35°C, and the current water temperature just obtained is 20°C, then the temperature difference between the two is 35-20=15°C, which is greater than the preset threshold, which means that the water outlet temperature of the water dispenser needs to be adjusted.

[0073] It should be noted that when it is determined that the outlet water temperature of the water dispenser needs to be adjusted, it can be determined whether to increase or decrease the temperature based on the difference between the target water temperature and the current water temperature.

[0074] In one embodiment of the present invention, the water dispenser also includes a heating component, the target water temperature is greater than the current water temperature, and the outlet water temperature is adjusted to the target water temperature according to the target water temperature, including: controlling the heating component to heat the water temperature to the target water temperature.

[0075] In an embodiment of the present invention, the water dispenser may further include a heating component. When it is determined that the outlet water temperature of the water dispenser needs to be adjusted and the target water temperature is greater than the current water temperature, the central controller of the water dispenser will activate a corresponding control strategy to drive the heating component to work.

[0076] First, the central controller can determine the heating power and duration according to the difference between the target water temperature and the current water temperature. For example, if the target water temperature is 80°C, and the current water temperature is only 20°C, the temperature difference between the two reaches 60°C. At this time, the central controller can determine that a larger heating power and a relatively longer heating time are required. It will adjust the circuit to allow more current to pass through the heating tube, allowing the heating tube to heat at a higher power and quickly increase the water temperature.

[0077] During the heating process, the temperature sensor in the water dispenser will continuously monitor the changes in water temperature in real time, and feed back the monitored data to the central controller. As the heating continues, the water temperature will continue to rise. When the water temperature approaches the target water temperature, for example, the water temperature reaches 78°C, the central controller will appropriately reduce the heating power of the heating component according to the preset control algorithm, so that the water temperature can rise to the target water temperature of 80°C more smoothly and accurately, avoiding the situation where the water temperature rises excessively and exceeds the target water temperature.

[0078] When the water temperature reaches the target temperature of 80℃, the central controller will stop supplying power to the heating component, causing the heating component to stop heating. At this time, the water outlet temperature of the water dispenser has been successfully adjusted to the target water temperature. After receiving the user's water outlet control instruction, the system can provide the user with hot water that meets their needs at any time according to the target water temperature.

[0079] In one embodiment of the present invention, the water dispenser also includes a condensation component, the target water temperature is lower than the current water temperature, and the outlet water temperature is adjusted to the target water temperature according to the target water temperature, including: controlling the condensation component to cool the water temperature to the target water temperature.

[0080] In the embodiment of the present invention, the condensing component of the water dispenser mainly plays the role of lowering the water temperature. The common condensing component includes key components such as a compressor, a condenser, a throttling device and an evaporator, and its working principle is based on a refrigeration cycle system.

[0081] The compressor is the power core of the entire refrigeration process. It will inhale low-temperature and low-pressure gaseous refrigerant, compress it into high-temperature and high-pressure gaseous refrigerant, and then transport it to the condenser. In the condenser, the high-temperature and high-pressure gaseous refrigerant will dissipate heat to the surrounding environment and gradually condense into high-pressure liquid refrigerant. In this process, heat is dissipated into the surrounding air, realizing the transformation of the refrigerant state. Then, the high-pressure liquid refrigerant passes through the throttling device, and its pressure and temperature will drop rapidly, becoming a low-temperature and low-pressure liquid refrigerant, and then flows into the evaporator. In the evaporator, the low-temperature and low-pressure liquid refrigerant will absorb the heat of the surrounding water and vaporize, thereby lowering the temperature of the water. It becomes a gaseous refrigerant and is then sucked into the compressor. This cycle repeats itself to achieve a continuous cooling effect.

[0082] When it is determined that the outlet water temperature of the water dispenser needs to be adjusted and the target water temperature is lower than the current water temperature, the central controller of the water dispenser will start the control operation of the condensing component to achieve the lowering of the water temperature. First, the central controller will reasonably arrange the parameters such as the cooling intensity and working time of the condensing component according to the difference between the target water temperature and the current water temperature. For example, the current water temperature is 30℃, and the target water temperature is set to 10℃, and the temperature difference reaches 20℃. The central controller will control the compressor to operate at a higher frequency based on this large temperature difference, so as to speed up the refrigeration cycle, enhance the refrigeration effect, and enable the evaporator to quickly absorb more heat from the water, causing the water temperature to drop as soon as possible.

[0083] During the cooling process, the water dispenser is also equipped with a temperature sensor, which will accurately monitor the water temperature in real time and continuously feed back the water temperature data to the central controller. As the cooling continues, the water temperature continues to decrease. When the water temperature approaches the target water temperature, for example, the water temperature drops to 12°C, the central controller will adjust the compressor's operating frequency and other parameters accordingly according to the preset control logic, appropriately reduce the cooling intensity, and allow the water temperature to drop smoothly and accurately to the target water temperature of 10°C, preventing the water temperature from dropping excessively and falling below the target water temperature.

[0084] Finally, when the water temperature reaches the target water temperature of 10°C, the central controller will issue a command to stop the compressor and other related components of the condensing assembly, ending the refrigeration process. At this time, the outlet water temperature of the water dispenser is accurately adjusted to the target water temperature. In this way, after receiving the user's water outlet control command, the user can be provided with low-temperature water that meets the needs. The present invention forms an effective closed-loop control system through the close cooperation between the condensing assembly, the temperature sensor and the central controller, ensuring that the outlet water temperature can be accurately adjusted to the target water temperature to meet the user's needs for different low-temperature water temperatures such as cold water or ice water.

[0085] In one embodiment of the present invention, the biometric information includes the user's facial information. Based on the biometric information, the target water temperature corresponding to the water dispenser is determined, including obtaining a first mapping relationship, the first mapping relationship including the outlet water temperature information corresponding to the facial information of different users; and querying the target water temperature corresponding to the user's facial information from the first mapping relationship.

[0086] In an embodiment of the present invention, the first mapping relationship is actually a data correspondence rule pre-established and stored in the database of the water dispenser. Before the water dispenser is put into use, it usually goes through a configuration or entry stage. The management personnel or the users themselves will associate the facial information of different users and their respective preferred water temperature information to form such a regular correspondence relationship set, which is the first mapping relationship.

[0087] For example, the facial image information of user A may be input through special management software or the setting interface of the water dispenser, such as being collected through a camera and stored in a certain image format, and the water temperature that user A is accustomed to drinking is set to 40°C; then the facial image information of user B is entered, and the preferred water temperature of 80°C is used for making tea, etc. These one-to-one related data together constitute a complete first mapping relationship, which provides a basis for subsequently quickly and accurately determining the target water temperature corresponding to each user.

[0088] This first mapping relationship can be stored in the local storage chip of the water dispenser or in a cloud server, so as to facilitate data synchronization between different water dispenser devices and multi-device sharing, thereby ensuring data security and convenient accessibility.

[0089] When the camera on the water dispenser obtains the facial information of the current user, its built-in image processing module will first perform feature extraction and recognition processing on the facial image, such as identifying the unique feature information such as the facial features, the distance ratio of key parts, etc., and converting it into digital feature data in a specific format so as to match and search with the facial information stored in the first mapping relationship.

[0090] Then, the central controller will traverse and query in the first mapping relationship based on these processed facial feature data. For example, after identification and comparison, it is found that the currently acquired facial feature data matches the facial information corresponding to user A in the first mapping relationship. Then, based on this corresponding relationship, the target water temperature corresponding to user A can be directly found, which is 40°C; if the facial information of user B is matched, the corresponding target water temperature can be determined to be 80°C.

[0091] The present invention can quickly and accurately find the target water temperature that meets the user's habits from a pre-set mapping relationship based on the recognized user's facial information, thereby laying the foundation for subsequent operations such as determining whether to adjust the water temperature and providing water according to the target water temperature, thereby realizing personalized water temperature services for different users.

[0092] In one embodiment of the present invention, the biometric information also includes gesture information. The target water temperature corresponding to the water dispenser is determined based on the biometric information, including: obtaining a second mapping relationship, the second mapping relationship including water outlet temperature information corresponding to different gestures; and querying the target water temperature corresponding to the user's gesture information from the second mapping relationship.

[0093] In the embodiment of the present invention, the second mapping relationship is a pre-constructed and stored data correspondence system, which can associate different user gestures with corresponding water outlet temperature information. This mapping relationship can be set when performing initial settings or function configurations on the water dispenser.

[0094] For example, in the setting program or operation interface corresponding to the water dispenser, the water temperature requirements corresponding to specific gestures can be defined. For example, the thumbs-up gesture is set to correspond to 40°C warm water, the index finger gesture corresponds to 60°C hot water, and the open palm gesture corresponds to 20°C cold water, and so on. Which gesture corresponds to which temperature can be set according to user needs and is not limited here.

[0095] This second mapping relationship data can be stored in the storage module inside the water dispenser, so that the device can quickly retrieve and use it locally, or it can be stored on a cloud storage platform connected to it. This not only facilitates data backup and management, but also enables synchronous updates and unified use among multiple water dispensers of the same type, ensuring that the water temperature can be determined based on the accurate second mapping relationship in different usage scenarios.

[0096] When the user makes a corresponding gesture in front of the water dispenser, the gesture recognition sensors equipped in the water dispenser, such as infrared sensors, depth cameras, etc., can capture key information such as the trajectory and shape of the gesture movement, and can detect and recognize the user's gesture. These sensors will digitize and extract features of the detected raw gesture data, such as the shape of the gesture, the extension state of the fingers, the direction and amplitude of the gesture movement, and convert it into a data form that can be compared and matched with the gesture information stored in the second mapping relationship.

[0097] The central controller will take the processed gesture feature data and search and match it in the second mapping relationship. For example, after identification and analysis, it is determined that the gesture made by the user is a thumbs-up. Then, according to the second mapping relationship, it can be quickly queried that the corresponding target water temperature is 40°C; if the gesture is identified as extending the index finger, the corresponding target water temperature is 60°C. The present invention can accurately find the corresponding target water temperature from the second mapping relationship based on the biometric information of the gesture made by the user, and then perform subsequent water temperature adjustment, water output control and other operations according to this target water temperature, providing users with a novel and convenient way to select water temperature to meet diverse usage needs.

[0098] In one embodiment of the present invention, it also includes: during the process of the water dispenser discharging hot water, determining whether body skin features are detected below the water outlet of the water dispenser; if body skin features are detected below the water outlet of the water dispenser, stopping water discharging and outputting an alarm message.

[0099] In the embodiment of the present invention, the water dispenser may be equipped with corresponding sensing detection equipment at the water outlet, commonly infrared sensing sensors or specific image recognition sensors, etc., and the specific one is not limited here.

[0100] Working principle and detection method of infrared sensing sensor: The infrared sensing sensor will continuously emit infrared signals and receive reflected infrared signals. When an object appears in the area below the water outlet, the infrared signal will be reflected back by the object. The sensor determines whether there is an object based on the changes in parameters such as the intensity and time of the reflected signal. If the object has temperature characteristics similar to those of human skin and reflection characteristics of infrared signals, the sensor can further determine that it is body skin that appears in the area. For example, when the user's hand accidentally reaches under the water outlet to get hot water, the skin of the hand will reflect infrared signals. After receiving these signals, the sensor can analyze them through internal algorithms and recognize that these are body skin characteristics.

[0101] Working principle and detection method of image recognition sensor: Image recognition sensor is generally a device such as a camera. It will collect image information of the area below the water outlet in real time, and then use image recognition technology to analyze and process the collected image. For example, it can identify whether there is an area in the image with features such as human skin color and texture. If a part that matches the preset human skin feature model is detected, it can be determined that body skin features appear below the water outlet. For example, by identifying the part of the image that matches the color and texture of human hand skin, it can be determined that there is body skin below the water outlet.

[0102] Once the above-mentioned detection means determine that there are body skin features below the water outlet, the control system of the water dispenser will immediately take corresponding measures. The central controller will send instructions to the water outlet valve and other related water outlet control components of the water dispenser to quickly close them, blocking the continued outflow of hot water, and preventing hot water from directly contacting human skin and causing burns and other injuries. For example, the water outlet that is originally flowing out hot water will quickly close its internal solenoid valve after receiving the instruction to stop discharging water, cutting off the water flow channel and preventing hot water from flowing out.

[0103] There are many ways to output warning information, aiming to alert users to potential dangers. On the one hand, the water dispenser itself may be equipped with a sound alarm device, such as a continuous beep or voice prompt, such as "There is an object below the water outlet, please stay away" to let users know the current situation. On the other hand, if the water dispenser has an Internet connection function or is connected to an external display device, it can also push an alarm notification on the mobile phone APP connected to it, or display alarm text on the display screen to inform the user that an abnormal situation is detected below the water outlet, reminding them to avoid dangerous operations and ensure safe use. The present invention can promptly detect potential scalding risks during the hot water discharge process, and take active measures to avoid danger, providing users with a safer and more reliable use experience.

[0104] The present invention discloses a water dispenser control method, which comprises the steps of acquiring biometric information of a user; determining a target water temperature corresponding to the water dispenser according to the biometric information; judging whether it is necessary to adjust the outlet water temperature of the water dispenser according to the target water temperature; if it is necessary to adjust the outlet water temperature of the water dispenser, adjusting the outlet water temperature to the target water temperature according to the target water temperature; and controlling the water dispenser to discharge water when a water discharge control instruction of the user is received; the biometric information of the user can be acquired to determine the corresponding target water temperature, and the personalized water temperature requirements of different users can be met, thereby improving the user experience; whether it is necessary to adjust the outlet water temperature of the water dispenser according to the target water temperature can be judged, and the outlet water temperature of the water dispenser can be adjusted only when the current water temperature is inconsistent with the target water temperature, thereby avoiding the water dispenser from continuously heating or cooling water, and especially when multiple people use the water dispenser and the water temperature requirements are different, thus effectively reducing the waste of energy.

[0105] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0106] like Figure 2, shows a water dispenser 20 provided by an embodiment of the present invention, the water dispenser includes an identification module 201, a central controller 202, a temperature adjustment component 203, and a water outlet component 204; the central controller 202 is respectively connected to the identification module 201, the water outlet component 204, and the temperature adjustment component 203, and the temperature adjustment component 203 is connected to the water outlet component 204;

[0107] Identification module 201, used to obtain the user's biometric information and send the biometric information to the central controller;

[0108] It should be noted that the recognition module can be a machine with image recognition function, such as a camera, and the specific one is not limited.

[0109] The central controller 202 is used to determine the target water temperature corresponding to the water dispenser according to the biometric information, and judge whether the outlet water temperature of the water dispenser needs to be adjusted according to the target water temperature. If the outlet water temperature of the water dispenser needs to be adjusted, the target water temperature is sent to the temperature adjustment component;

[0110] The temperature adjustment component 203 is used to adjust the outlet water temperature to the target water temperature according to the target water temperature;

[0111] The water outlet component 204 is used to control the water outlet of the water dispenser when receiving a water outlet control instruction from the user.

[0112] In one embodiment of the present invention, the water dispenser 20 may further include a mainboard module 205, which may process and transmit data to ensure the coordinated operation of the modules. It may also receive status feedback data from the temperature control component and the water outlet component. For example, the temperature control component may feedback the current water temperature information, and the water outlet component may feedback the current water outlet status. The mainboard module may parse these feedback data to understand the actual working conditions of each module.

[0113] When the central controller needs the thermostat to heat the water to a specific temperature, the central controller will send the heating instruction to the mainboard module, and the mainboard module will accurately transmit the instruction to the thermostat. Similarly, during the heating process, the thermostat will feed back the water temperature change data to the central controller through the mainboard module.

[0114] The mainboard module can pass the user's operating instructions on the interactive interface to the corresponding module. For example, when the user selects the water outlet operation on the interactive interface, this operating instruction will first be transmitted to the mainboard module, and then the mainboard module will pass it to the water outlet module to ensure that the water outlet module can correctly perform the water outlet operation. The present invention processes and transmits data through the mainboard module, thereby ensuring close collaboration and efficient operation between the modules in the water dispenser, providing convenience for users.

[0115] The present invention discloses a water dispenser, which acquires biometric information of a user; determines a target water temperature corresponding to the water dispenser according to the biometric information; determines whether the outlet water temperature of the water dispenser needs to be adjusted according to the target water temperature; if the outlet water temperature of the water dispenser needs to be adjusted, adjusts the outlet water temperature to the target water temperature according to the target water temperature; and controls the water dispenser to discharge water when a water discharge control instruction of the user is received; the biometric information of the user can be acquired to determine the corresponding target water temperature, and the personalized water temperature requirements of different users can be met, thereby improving the user experience; it can be determined whether the outlet water temperature of the water dispenser needs to be adjusted according to the target water temperature, and the water temperature of the water dispenser is adjusted only when the current water temperature is inconsistent with the target water temperature, thereby avoiding the water dispenser from continuously heating or cooling water, especially when multiple people use the water dispenser and have different water temperature requirements, thereby effectively reducing energy waste.

[0116] In one embodiment of the present invention, the central controller is also used to obtain the current water temperature; determine the temperature difference between the target water temperature and the current water temperature; if the absolute value of the temperature difference is less than a preset threshold, it is determined that there is no need to adjust the water outlet temperature of the water dispenser, and when a water outlet control instruction from the user is received, the water outlet of the water dispenser is controlled.

[0117] In one embodiment of the present invention, the central controller is also used to determine that the outlet water temperature of the water dispenser needs to be adjusted if the absolute value of the temperature difference is greater than a preset threshold.

[0118] In one embodiment of the present invention, the temperature adjustment component includes a heating component, the target water temperature is greater than the current water temperature, and the central controller is used to control the heating component to heat the water to the target water temperature.

[0119] like Figure 3 , showing a structural block diagram of another water dispenser provided by an embodiment of the present invention, the temperature control component 203 may also include a heating component 2031. When the outlet water temperature of the water dispenser needs to be adjusted and the target water temperature is greater than the current water temperature, the heating component 2031 may heat the water temperature to the target water temperature according to the control instruction of the central controller 202.

[0120] In one embodiment of the present invention, the temperature regulating component includes a cooling component, the target water temperature is lower than the current water temperature, and the central controller is used to control the condensing component to cool the water temperature to the target water temperature.

[0121] like Figure 3 The temperature regulating component 203 may further include a cooling component 2032. When the outlet water temperature of the water dispenser needs to be adjusted and the target water temperature is lower than the current water temperature, the heating component 2032 may cool the water temperature to the target water temperature according to the control instruction of the central controller 202.

[0122] In one embodiment of the present invention, the biometric information includes the user's facial information, and the central controller is used to obtain a first mapping relationship, the first mapping relationship including the outlet water temperature information corresponding to the facial information of different users; and query the target water temperature corresponding to the user's facial information from the first mapping relationship.

[0123] In one embodiment of the present invention, the biometric information also includes gesture information, and the central controller is used to obtain a second mapping relationship, which includes water outlet temperature information corresponding to different gestures; and query the target water temperature corresponding to the user's gesture information from the second mapping relationship.

[0124] In one embodiment of the present invention, the water dispenser also includes a water outlet detection component, which is used to determine whether body skin features are detected below the water outlet of the water dispenser during the process of the water dispenser discharging hot water; if body skin features are detected below the water outlet of the water dispenser, the water dispenser is controlled to stop discharging water and output an alarm message.

[0125] In one embodiment of the present invention, the water dispenser can also be provided with a child lock protection function. The child lock protection function can be in a locked state during normal operation to prevent children from misoperating the water dispenser and avoid accidents such as scalding. When the child lock is turned on, certain operations of the water dispenser to dispense hot water will be prohibited. The child lock can be unlocked by face recognition. When the recognition module is successfully matched, if the system determines that the current user is an adult, the child lock unlocking operation can be triggered. Figure 4 , shows another water dispenser 20 provided by an embodiment of the present invention. The water dispenser may include a locking mechanism 207. When the recognition module 201 sends the user's facial information to the central controller 202, the central controller may send an instruction to the mainboard module 205 after receiving the signal and determining that the current user is an adult. The mainboard module 205 then controls the relevant locking mechanism 207 to unlock the child lock function of the water outlet component. For example, the child lock solenoid valve of the water outlet module is controlled to open, allowing the user to perform normal water outlet operations. The child lock unlocking method based on facial recognition of the present invention provides a convenient and safe user verification mechanism, ensuring that only legitimate adult users can operate the water dispenser, thereby ensuring the safety of children to a certain extent.
