[0055] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0056] The water heater control method provided in the embodiment of the present application is used to control the water heater. Figure 1 As shown, the water heater includes a water temperature regulating device and a water outlet assembly 10. The water temperature regulating device is used to regulate the outlet water temperature of the water outlet assembly 10. Specifically, the water temperature regulating device can be arranged in the water heater body, and the water heater body is connected to at least one cold water inlet pipe 12 and a hot water outlet pipe 14. The cold water inlet pipe 12 is used to connect cold water to the water heater body, and then the water temperature regulating device heats the connected cold water. The heated water is output through the hot water outlet pipe 14. The water outlet assembly 10 is connected to the hot water outlet pipe 14, and the hot water output by the hot water outlet pipe 14 is discharged through the water outlet assembly 10 and reaches the target. Among them, the type of the water outlet assembly 10 is not limited, for example, it can be a shower head, or it can be other. The type of the target is also not limited, for example, it can be a human body, or it can be other objects, such as pets.

[0057] The water heater control method provided in the embodiments of the present application can be executed by a processor within the water heater, or by a terminal or server in communication with the water heater. The terminal may be, but is not limited to, various personal computers, laptops, smartphones, tablet computers, IoT devices, and portable wearable devices. The server may be an independent physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server providing cloud computing services.

[0058] In an exemplary embodiment, Figure 2 As shown, a water heater control method is provided, which is described by taking the method executed by a processor in the water heater as an example, and includes the following steps 202 to 204.

[0059] in:

[0060] Step 202: Obtain the distance between the water outlet component and the object of action.

[0061] The target is the target of the water outlet component. After the water outlet component discharges water, it will reach the target after a certain distance, so that the target receives hot water.

[0062] The type of the object is not limited, for example, it can be a human body or other objects, such as pets. Generally, the object is a movable object. When the object uses the water outlet component to discharge water, the position of the object may move, thereby changing the distance between the object and the water outlet component. Figure 3 As shown, the distance between the target and the water outlet assembly in the left image is smaller than that in the right image. When the distance changes, the water from the water outlet assembly travels different distances in the air, which affects the water temperature differently, thus changing the temperature of the hot water received by the target.

[0063] There is not only one way for the processor to obtain the distance between the water outlet assembly and the object. For example, the distance between the water outlet assembly and the object can be detected by a distance detection device, and the detected distance value can be sent to the processor.

[0064] The distance detection device can be provided on the water outlet component, so that the detected distance between the water outlet component and the target object is more accurate. The specific setting position of the distance detection device can be determined according to the type of the water outlet component. Taking the water outlet component as a shower head as an example, the shower head includes a nozzle and a handle. The distance detection device can be provided on the handle, and can further be provided at a position where the handle is 2-5 cm away from the nozzle, thereby reducing the impact of the water outlet of the nozzle on the working performance of the distance detection device. The type of distance detection device is not limited, for example, it can be an ultrasonic sensor or an infrared sensor, etc., which can be determined according to actual needs. When the distance detection device includes an infrared sensor, the infrared sensor can detect the temperature of the target object and the surrounding environment, determine the target object based on the temperature, and make the detection of the distance between the water outlet component and the target object more accurate.

[0065] Furthermore, the number of distance detection devices may be one or more. When there are multiple distance detection devices, they may be located at different locations to obtain multiple distances. The distance between the water outlet assembly and the object of action may be determined by combining multiple distances, for example, by taking the average of the multiple distances as the final distance between the water outlet assembly and the object of action. This reduces detection errors caused by a single distance detection device, thereby improving the accuracy of the acquired distance.

[0066] Step 204: Adjust the working state of the water temperature regulating device according to the distance.

[0067] The distance between the water outlet component and the object of action is different, and the length of the path that the water from the water outlet component travels to reach the object of action is different. The degree of influence of the path length on the water temperature is also different.

[0068] For example, the greater the distance between the water outlet assembly and the target, the longer the path the water from the water outlet assembly takes to reach the target, the greater the impact on the water temperature, and generally a greater drop in water temperature, resulting in a greater difference between the temperature of the hot water received by the target and the temperature of the water from the water outlet assembly. The smaller the distance between the water outlet assembly and the target, the shorter the path the water from the water outlet assembly takes to reach the target, and the smaller the impact on the water temperature, and generally a smaller drop in water temperature, resulting in a smaller difference between the temperature of the hot water received by the target and the temperature of the water from the water outlet assembly.

[0069] To compensate for the effect of distance on temperature attenuation, the processor can adjust the operating state of the water temperature control device based on distance. For example, when the distance is large, the processor can control the water temperature control device to increase the heating power to increase the outlet water temperature of the water outlet component, thereby increasing the temperature of the hot water received by the target to compensate for the cooling effect caused by the large distance. When the distance is small, the processor can control the water temperature control device to maintain the heating power to prevent the outlet water temperature from rising further.

[0070] In the above-mentioned water heater control method, the water heater includes a water temperature regulating device and a water outlet assembly. The water temperature regulating device is used to adjust the outlet water temperature of the water outlet assembly. The water heater control method includes: obtaining the distance between the water outlet assembly and an object of action, where the object of action is the object of water outlet of the water outlet assembly, and adjusting the operating state of the water temperature regulating device according to the distance. The operating state of the water temperature regulating device is adjusted based on the distance between the water outlet assembly and the object of action, thereby adjusting the outlet water temperature of the water outlet assembly. This allows the water heater to automatically adjust the temperature according to the distance, thereby resolving the problem of water temperature discomfort caused by distance changes. The outlet water temperature of the water outlet assembly can better meet user needs without having to heat the water to an excessively high temperature, thereby reducing energy waste and improving the operating reliability of the water heater.

[0071] In an exemplary embodiment, Figure 4 As shown, step 204 includes steps 402 to 404 .

[0072] in:

[0073] Step 402: Calculate the target temperature based on the distance.

[0074] After the processor receives the distance between the water outlet component and the object of action, it can calculate the target temperature based on the distance based on a preset algorithm.

[0075] Among them, the preset algorithm is not unique. For example, the preset algorithm can be a linear relationship between distance and target temperature, and the linear relationship can be: T_target = T0 + k*(d-d0). According to this relationship, the target temperature can be calculated based on the distance. Among them, T_target is the target temperature, d is the distance between the water outlet component and the object of action, T0 is the reference temperature, d0 is the reference distance, and k is the temperature adjustment coefficient. T0, d0 and k are known values, and their specific values ​​can be adjusted according to the experimental data of the actual laboratory and are not limited.

[0076] Step 404: Adjust the working state of the water temperature regulating device according to the target temperature.

[0077] The target temperature reflects the distance between the water component and the object being treated. It can be understood as the temperature that the water outlet of the water outlet component should reach after compensating for the effect of distance on water temperature attenuation.

[0078] Therefore, once the target temperature is determined, the operating state of the water temperature control device can be adjusted accordingly. For example, when the target temperature is high, the water temperature control device can be controlled to increase power to raise the outlet water temperature of the water outlet component, thereby increasing the temperature of the hot water received by the target to compensate for the cooling effect caused by the large distance. When the target temperature is low, the processor can control the water temperature control device to maintain heating power to prevent the outlet water temperature from rising further.

[0079] In this embodiment, after calculating the target temperature based on the distance, the working state of the water temperature regulating device is adjusted according to the target temperature. The distance situation is reflected by the target temperature, and then the working state of the water temperature regulating device is adjusted according to the target temperature, making the control of the temperature regulating device more accurate and quick.

[0080] In an exemplary embodiment, Figure 5 As shown, step 404 includes steps 502 to 504.

[0081] in:

[0082] Step 502: Obtain the outlet water temperature of the water outlet component and the set temperature of the water heater.

[0083] The outlet water temperature of the water outlet component is the actual outlet water temperature of the water outlet component.

[0084] The processor may obtain the outlet water temperature of the water outlet component in a manner that is not limited to one embodiment. For example, the outlet water temperature of the water outlet component may be detected by a temperature detection device, and the detected outlet water temperature may be sent to the processor.

[0085] A temperature detection device can be installed on the water outlet assembly to more accurately detect the outlet water temperature. The specific location of the temperature detection device can be determined by the type of water outlet assembly. For example, if the water outlet assembly is a shower head, which includes a nozzle and handle, the temperature detection device can be installed on the nozzle head, allowing direct contact with the water outlet assembly, thereby improving the accuracy of the detected water outlet temperature.

[0086] The set temperature of the water heater is the target heating temperature set in the water heater. It is generally set by the user and is the temperature desired by the user. It can also be determined according to default rules. The processor can obtain the set temperature of the water heater by sending a user instruction to set the temperature through an interactive device, and the processor parses the user instruction obtained from the interactive device to obtain the set temperature. The interactive device can be a button, a touch screen, or a voice control device, etc., which are not limited here.

[0087] Step 504 : When the target temperature is not equal to the outlet water temperature, the working state of the water temperature regulating device is adjusted according to the target temperature and the set temperature or the outlet water temperature.

[0088] If the target temperature and the outlet water temperature are not equal, it indicates that the current outlet water temperature cannot meet the user's water temperature requirements at the current distance. In this case, the processor can adjust the operating state of the water temperature control device based on the target temperature and the set temperature. Alternatively, the processor can adjust the operating state of the water temperature control device based on the target temperature and the outlet water temperature. This will bring the target temperature closer to the outlet water temperature, thereby meeting the user's water temperature requirements at the current distance.

[0089] In this embodiment, the outlet water temperature of the water outlet assembly and the set temperature of the water heater are obtained. If the target temperature and the outlet water temperature are not equal, the operating state of the water temperature regulating device is adjusted based on the target temperature and the set temperature or the outlet water temperature. Thus, based on the required hot water temperature, the actual outlet hot water temperature, and the set temperature, the operating state of the water temperature regulating device can be adjusted when the water heater is in different operating states to bring the target temperature closer to the outlet water temperature, thereby reducing the impact of distance on water temperature and meeting the user's water temperature requirements at the current distance.

[0090] In an exemplary embodiment, Figure 6 As shown, in step 504, the step of adjusting the working state of the water temperature regulating device according to the target temperature and the set temperature or the outlet water temperature includes steps 602 to 604.

[0091] Step 602: When the target temperature is greater than the set temperature, increase the set temperature to the target temperature.

[0092] Step 604: Adjust the working state of the water temperature regulating device according to the increased set temperature.

[0093] If the target temperature is greater than the set temperature, it indicates that at the current distance, if the water heater is heating at the set temperature and the outlet water temperature is equal to or close to the set temperature, the outlet water temperature will attenuate over distance and will be too low when the water reaches the target, failing to meet the target's water temperature requirements.

[0094] Therefore, in this case, the processor updates the set temperature according to the target temperature and increases the set temperature to the target temperature.

[0095] Afterwards, the processor adjusts the working state of the water temperature regulating device according to the increased set temperature, so that the water temperature regulating device operates with the increased set temperature as the target temperature, for example, increasing the heating power to increase the outlet water temperature, thereby compensating for the attenuation of water temperature caused by distance, and avoiding the water temperature of the water outlet component being too low when it reaches the target object, so as to meet the user's hot water use needs.

[0096] In this embodiment, when the target temperature is greater than the set temperature, the set temperature is increased to the target temperature, and the working state of the water temperature regulating device is adjusted according to the increased set temperature. This can compensate for the attenuation of the water temperature of the water outlet component caused by the distance, and avoid the water temperature of the water outlet component being too low when it reaches the target object, so as to meet the user's hot water use needs.

[0097] The structure of the water temperature regulating device is not unique. In an exemplary embodiment, Figure 1 As shown, the water temperature regulating device includes a heating component 16 and a hot and cold water mixing valve 18. The heating component 16 is used to heat the water output from the water outlet component 10, and the hot and cold water mixing valve 18 is used to adjust the ratio of hot and cold water output from the water outlet component.

[0098] The heating assembly 16 can be disposed within the water heater body, which is connected to at least one cold water inlet pipe 12 and a hot water outlet pipe 14. The cold water inlet pipe 12 is used to bring cold water into the water heater body. The heating assembly 16 then heats the incoming cold water. The heated water is then output through the hot water outlet pipe 14. A hot and cold water mixing valve 18 is disposed in communication with the cold water inlet pipe 12, the hot water outlet pipe 14, and the water outlet assembly 10. The cold water output from the cold water inlet pipe 12 and the hot water output from the hot water outlet pipe 14 are mixed at the hot and cold water mixing valve 18 and then delivered to the water outlet assembly 10. Depending on the degree of opening of the hot and cold water mixing valve 18, the ratio of cold water to hot water reaching the water outlet assembly 10 varies, resulting in different outlet temperatures of the water from the water outlet assembly 10.

[0099] Based on the above structure, in an exemplary embodiment, as Figure 7 As shown, step 604 includes steps 702 to 704. Among them:

[0100] Step 702: Increase the heating power of the heating component according to the increased set temperature, and control the heating component to heat the water to the increased set temperature.

[0101] During the control of the heating component, the processor uses the increased set temperature as the target heating temperature of the heating component and increases the heating power of the heating component by an amount determined by the increased set temperature. Thus, after the heating power of the heating component is increased, the heating component can be controlled to heat the water to the increased set temperature.

[0102] Step 704: Adjust the opening of the hot and cold water mixing valve to fully output hot water.

[0103] During control of the hot and cold water mixing valve, the processor adjusts the opening of the hot and cold water mixing valve to adjust the ratio of cold water to hot water controlled by the hot and cold water mixing valve. Specifically, the processor adjusts the opening of the hot and cold water mixing valve to a state where full hot water is output. The specific value of the opening can be 0, which is determined based on the structure of the hot and cold water mixing valve.

[0104] In this embodiment, the water temperature regulating device includes a heating assembly and a hot and cold water mixing valve. The heating assembly is used to heat the water flowing out of the water outlet assembly, and the hot and cold water mixing valve is used to adjust the ratio of hot and cold water flowing out of the water outlet assembly. When the target temperature is greater than the set temperature, the heating power of the heating assembly is increased according to the increased set temperature, the heating assembly is controlled to heat the water to the increased set temperature, and the opening of the hot and cold water mixing valve is adjusted to fully hot water output. This allows the water outlet temperature of the water outlet assembly to be closer to the increased set temperature, that is, closer to the target temperature, so that the temperature of the water received by the target object is closer to the actual temperature requirement.

[0105] In one exemplary embodiment, the water temperature control device includes a hot / cold water mixing valve, which is used to adjust the ratio of hot / cold water in the water outlet assembly. The hot / cold water mixing valve is connected to the cold water inlet pipe, the hot water outlet pipe, and the water outlet assembly. Cold water from the cold water inlet pipe and hot water from the hot water outlet pipe are mixed at the hot / cold water mixing valve before being delivered to the water outlet assembly. Different openings of the hot / cold water mixing valve result in different ratios of cold water to hot water reaching the water outlet assembly, resulting in different water temperatures at the outlet assembly.

[0106] Based on the above structure, in another exemplary embodiment, as Figure 8 As shown, in step 504, the step of adjusting the working state of the water temperature regulating device according to the target temperature and the set temperature or the outlet water temperature includes steps 802 to 806.

[0107] Step 802 : When the target temperature is less than or equal to the set temperature, the water temperature compensation temperature is calculated based on the difference between the target temperature and the outlet water temperature.

[0108] If the target temperature is less than or equal to the set temperature, it indicates that at the current distance, if the water heater is heating at the set temperature and the outlet water temperature is equal to or close to the set temperature, the outlet water temperature may be too high when it reaches the target due to distance attenuation, and may not meet the target's water temperature requirements.

[0109] Therefore, in this case, the processor calculates the difference between the target temperature and the outlet water temperature, and then calculates the water temperature compensation temperature based on the difference between the target temperature and the outlet water temperature. The water temperature compensation temperature can be calculated using a PID (Proportional Integral Derivative) algorithm. Specifically, it can be calculated using the following formula:

[0110] ΔT=Kp*(T_target-T_current)+Ki∫(T_target-T_current)dt+Kdd(T_target-T_current) / dt)

[0111] Where ΔT is the water temperature compensation, Kp is the proportional parameter, Ki is the integral parameter, Kdd is the differential parameter, T_target is the target temperature, and T_current is the outlet water temperature. Kp, Ki, and Kdd are constants that can be determined experimentally.

[0112] Step 804 : Match the opening compensation number corresponding to the water temperature compensation temperature according to the preset corresponding relationship.

[0113] The preset corresponding relationship may be pre-stored in the processor and may be obtained by testing and fitting under laboratory conditions.

[0114] After the processor calculates the water temperature compensation temperature, it can match an opening compensation number corresponding to the water temperature compensation temperature in the preset corresponding relationship according to the preset corresponding relationship.

[0115] Step 806: Adjust the opening of the hot and cold water mixing valve according to the opening compensation value.

[0116] The opening compensation number represents the degree of opening of the hot and cold water mixing valve. After the processor matches and obtains the opening compensation number, it adjusts the opening of the hot and cold water mixing valve based on the opening compensation number. This ensures that when the hot and cold water mixing valve is opened at the adjusted opening, the temperature of the mixed hot and cold water is closer to the target temperature.

[0117] In this embodiment, when the target temperature is less than or equal to the set temperature, the water temperature compensation temperature is calculated based on the difference between the target temperature and the outlet water temperature. According to the preset correspondence, the opening compensation number corresponding to the water temperature compensation temperature is matched, and the opening of the hot and cold water mixing valve is adjusted according to the opening compensation number. Thus, the opening of the hot and cold water mixing valve is adjusted according to the difference between the target temperature and the outlet water temperature, so that the ratio of cold water in the hot and cold water is appropriate, and the outlet water temperature of the water outlet component can be appropriately lowered, so that the outlet water temperature can be closer to the target temperature, and the water temperature reaching the target object is more accurate.

[0118] In an exemplary embodiment, Figure 9As shown, step 806 includes step 902 and step 904 .

[0120] Step 902: When the opening compensation number is greater than 0, the hot and cold water mixing valve is controlled to rotate forward to increase the proportion of hot water output.

[0121] Step 904: When the opening compensation number is less than 0, the hot and cold water mixing valve is controlled to reverse to reduce the hot water output ratio.

[0122] When the opening compensation value is greater than 0, it indicates that the target temperature is greater than the outlet water temperature. In this case, the processor controls the hot and cold water mixing valve to rotate forward to increase the proportion of hot water outlet, thereby raising the outlet water temperature and bringing the outlet water temperature closer to the target temperature.

[0123] When the opening compensation value is less than 0, it indicates that the target temperature is lower than the outlet water temperature. In this case, the processor controls the hot and cold water mixing valve to reverse to reduce the proportion of hot water outlet, thereby lowering the outlet water temperature and bringing the outlet water temperature closer to the target temperature.

[0124] In this embodiment, when the opening compensation number is greater than 0, the hot and cold water mixing valve is controlled to rotate forward to increase the proportion of hot water output. When the opening compensation number is less than 0, the hot and cold water mixing valve is controlled to rotate backward to reduce the proportion of hot water output. Thus, by controlling the hot and cold water mixing valve differently based on different opening compensation numbers, the outlet water temperature can be adjusted closer to the target temperature, ensuring that the outlet water temperature better meets user needs.

[0125] In an exemplary embodiment, Figure 10 As shown, after step 202 and before step 204, the water heater control method further includes steps 1003 to 1004. Among them:

[0126] Step 1003: Compare the distance with a preset shower distance range.

[0127] Step 1004 : If the distance is within the preset shower distance range, execute step 204 .

[0128] The preset shower distance range is a range between a lower distance limit and an upper distance limit. The specific values ​​of the lower distance limit and the upper distance limit can be determined based on historical data or statistically determined under laboratory conditions.

[0129] If the distance is within the preset shower distance range, it indicates that the subject is using the water output of the water outlet component, such as taking a shower. In this case, subsequent steps are performed to obtain the distance and adjust the working state of the water temperature control device according to the distance.

[0130] In this embodiment, the distance is compared with the preset shower distance range. When the distance is within the preset shower distance range, step 204 is executed. When the object is using the water outlet component, the working state of the water temperature regulating device can be adjusted so that the outlet water temperature can meet the demand, thereby reducing useless adjustments to the water temperature regulating device and saving resources.

[0131] Furthermore, in an exemplary embodiment, after step 1003 , the water heater control method further includes the step of controlling the water heater to enter a standby mode when the time duration during which the distance exceeds the preset shower distance range reaches a preset time duration.

[0132] When the distance exceeds the preset shower distance range, it indicates that the user is not using the water outlet assembly. In this case, the processor measures the length of time the distance is outside the preset shower distance range. If the distance exceeds the preset shower distance range for a predetermined period of time, indicating that the user has left, the processor controls the water heater to enter standby mode to save energy.

[0133] In one embodiment, if the distance exceeds the preset shower distance range, the model of the distance detection device, the communication mechanism between the processor and the distance detection device, or some special feedback from the distance detection device can be used to determine whether the distance detection device is faulty or whether the distance detection device is submerged in water. If so, the water heater automatically switches to manual mode and operates according to the set temperature.

[0134] In this embodiment, when the distance exceeds the preset shower distance range for a preset time period, the water heater is controlled to enter the standby mode, which can reduce resource waste.

[0135] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0136] Based on the same inventive concept, embodiments of the present application further provide a water heater control device for implementing the aforementioned water heater control method. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more water heater control device embodiments provided below can be found in the aforementioned limitations of the water heater control method and will not be further elaborated here.

[0137] In an exemplary embodiment, Figure 11 As shown, a water heater control device is provided. The water heater includes a water temperature regulating device and a water outlet component. The water temperature regulating device is used to regulate the outlet water temperature of the water outlet component. The water heater control device includes a distance acquisition module 1102 and a temperature adjustment module 1104, wherein:

[0138] The distance acquisition module 1102 is used to acquire the distance between the water outlet component and the action object; the action object is the water outlet action object of the water outlet component.

[0139] The temperature adjustment module 1104 is used to adjust the working state of the water temperature adjustment device according to the distance.

[0140] In an exemplary embodiment, the temperature adjustment module is further configured to calculate a target temperature based on the distance; and adjust the working state of the water temperature regulating device based on the target temperature.

[0141] In an exemplary embodiment, the temperature adjustment module is also used to obtain the water outlet temperature of the water outlet component and the set temperature of the water heater; when the target temperature is not equal to the water outlet temperature, the working state of the water temperature regulating device is adjusted according to the target temperature and the set temperature or the water outlet temperature.

[0142] In an exemplary embodiment, the temperature adjustment module is further configured to increase the set temperature to the target temperature when the target temperature is greater than the set temperature; and adjust the working state of the water temperature regulating device according to the increased set temperature.

[0143] In an exemplary embodiment, the water temperature regulating device includes a heating component and a hot and cold water mixing valve. The heating component is used to heat the water output from the water outlet component, and the hot and cold water mixing valve is used to adjust the ratio of hot and cold water in the water output from the water outlet component; the temperature adjustment module is also used to increase the heating power of the heating component according to the increased set temperature, control the heating component to heat the water to the increased set temperature; and adjust the opening of the hot and cold water mixing valve to full hot water output.

[0144] In an exemplary embodiment, the water temperature regulating device includes a hot and cold water mixing valve, which is used to adjust the ratio of hot and cold water in the water outlet of the water outlet component; the temperature adjustment module is also used to calculate the water temperature compensation temperature based on the difference between the target temperature and the outlet water temperature when the target temperature is less than or equal to the set temperature; match the opening compensation number corresponding to the water temperature compensation temperature according to a preset corresponding relationship; and adjust the opening of the hot and cold water mixing valve according to the opening compensation number.

[0145] In an exemplary embodiment, the temperature adjustment module is also used to control the hot and cold water mixing valve to rotate forward when the opening compensation number is greater than 0 to increase the proportion of hot water output; and to control the hot and cold water mixing valve to rotate reverse when the opening compensation number is greater than 0 to reduce the proportion of hot water output.

[0146] In an exemplary embodiment, the water heater control device also includes a distance judgment module, which is used to compare the distance with a preset shower distance range after the distance acquisition module obtains the distance between the water outlet component and the object of action, and before the temperature adjustment module adjusts the working state of the water temperature adjustment device according to the distance; when the distance is within the preset shower distance range, the temperature adjustment module adjusts the working state of the water temperature adjustment device according to the distance.

[0147] In an exemplary embodiment, the water heater control device further includes a standby control module, which is configured to control the water heater to enter a standby mode when the distance judgment module compares the distance with a preset shower distance range and the distance exceeds the preset shower distance range for a preset time period.

[0148] Each module in the water heater control device described above may be implemented in whole or in part through software, hardware, or a combination thereof. Each module may be embedded in or independent of a processor in a computer device in the form of hardware, or may be stored in a memory in the computer device in the form of software, so that the processor can call and execute the corresponding operations of each module.

[0149] This application also provides a water heater control device, comprising a water temperature regulating device and a water outlet assembly. The water temperature regulating device is configured to regulate the outlet temperature of the water from the water outlet assembly. The water heater control device comprises a distance detecting device and a processor, wherein the distance detecting device is disposed in the water outlet assembly and connected to the processor. The distance detecting device is configured to detect the distance between the water outlet assembly and an object of action and transmit the detected distance to the processor, which is configured to execute the method of any of the above embodiments.

[0150] Among them, Figure 1As shown, the water heater includes a water temperature regulating device and a water outlet assembly 10. The water temperature regulating device is used to regulate the outlet water temperature of the water outlet assembly 10. Specifically, the water temperature regulating device can be arranged in the water heater body, and the water heater body is connected to at least one cold water inlet pipe 12 and a hot water outlet pipe 14. The cold water inlet pipe 12 is used to connect cold water to the water heater body, and then the water temperature regulating device heats the connected cold water. The heated water is output through the hot water outlet pipe 14. The water outlet assembly 10 is connected to the hot water outlet pipe 14, and the hot water output by the hot water outlet pipe 14 is discharged through the water outlet assembly 10 and reaches the target. Among them, the type of the water outlet assembly 10 is not limited, for example, it can be a shower head, or it can be other. The type of the target is also not limited, for example, it can be a human body, or it can be other objects, such as pets.

[0151] The distance detection device can be provided on the water outlet component, so that the detected distance between the water outlet component and the target object is more accurate. The specific setting position of the distance detection device can be determined according to the type of the water outlet component. Taking the water outlet component as a shower head as an example, the shower head includes a nozzle and a handle. The distance detection device can be provided on the handle, and can further be provided at a position where the handle is 2-5 cm away from the nozzle, thereby reducing the impact of the water outlet of the nozzle on the working performance of the distance detection device. The type of distance detection device is not limited, for example, it can be an ultrasonic sensor or an infrared sensor, etc., which can be determined according to actual needs. When the distance detection device includes an infrared sensor, the infrared sensor can detect the temperature of the target object and the surrounding environment, determine the target object based on the temperature, and make the detection of the distance between the water outlet component and the target object more accurate.

[0152] Furthermore, the number of distance detection devices may be one or more. When there are multiple distance detection devices, they may be located at different locations to obtain multiple distances. The distance between the water outlet assembly and the object of action may be determined by combining multiple distances, for example, by taking the average of the multiple distances as the final distance between the water outlet assembly and the object of action. This reduces detection errors caused by a single distance detection device, thereby improving the accuracy of the acquired distance.

[0153] The above-mentioned water heater control device adjusts the working state of the water temperature regulating device based on the distance between the water outlet component and the object of action, thereby adjusting the water outlet temperature of the water outlet component, so that the water heater can automatically adjust the temperature according to the distance, solving the problem of water temperature discomfort caused by distance changes, so that the water outlet temperature of the water outlet component can better meet user needs, and there is no need to heat the water to an excessively high temperature, reducing energy waste, and thus improving the working reliability of the water heater.

[0154] In an exemplary embodiment, the water heater control device further includes a temperature detection device connected to the processor; the temperature detection device is used to detect the outlet water temperature of the water outlet component and send the temperature to the processor.

[0155] A temperature detection device can be installed on the water outlet assembly to more accurately detect the outlet water temperature. The specific location of the temperature detection device can be determined by the type of water outlet assembly. For example, if the water outlet assembly is a shower head, which includes a nozzle and handle, the temperature detection device can be installed on the nozzle head, allowing direct contact with the water outlet assembly, thereby improving the accuracy of the detected water outlet temperature.

[0156] The present application also provides a water heater system, including a water heater and a water heater control device of any of the above embodiments, the water heater including a water temperature regulating device and a water outlet component, the water temperature regulating device being used to regulate the outlet water temperature of the water outlet component.

[0157] The above-mentioned water heater system adjusts the working state of the water temperature regulating device based on the distance between the water outlet component and the object of action, thereby adjusting the water outlet temperature of the water outlet component, so that the water heater can automatically adjust the temperature according to the distance, solving the problem of water temperature discomfort caused by distance changes, so that the water outlet temperature of the water outlet component can better meet user needs, and there is no need to heat the water to an excessively high temperature, reducing energy waste, and thus improving the working reliability of the water heater.

[0158] In an exemplary embodiment, the water temperature regulating device includes a heating component and a hot and cold water mixing valve. The heating component is used to heat the water output from the water outlet component, and the hot and cold water mixing valve is used to adjust the ratio of hot and cold water in the water output from the water outlet component.

[0159] The heating assembly can be arranged in the water heater body, which is connected to at least one cold water inlet pipe and a hot water outlet pipe. The cold water inlet pipe is used to connect cold water to the water heater body, and then the heating assembly heats the connected cold water. The heated water is output through the hot water outlet pipe. The hot and cold water mixing valve is connected to the cold water inlet pipe, the hot water outlet pipe and the water outlet assembly. The cold water output from the cold water inlet pipe and the hot water output from the hot water outlet pipe are mixed at the hot and cold water mixing valve and then transmitted to the water outlet assembly. When the opening degree of the hot and cold water mixing valve is different, the ratio of cold water to hot water reaching the water outlet assembly is different, and thus the outlet water temperature of the water outlet assembly is different. The outlet water temperature can be increased or decreased by the heating assembly and the hot and cold water mixing valve, which is convenient to control.

[0160] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment, the water heater system includes a water heater and a water heater control device. The water heater includes a water temperature regulating device and a water outlet component. The water temperature regulating device includes a heating component and a hot and cold water mixing valve. The water heater control device includes a distance detection device, a temperature detection device and a processor. Taking the human body as the object of action and the sprinkler nozzle as an example, the distance detection device detects the distance between the human body and the sprinkler nozzle in real time and transmits the distance signal to the processor. The processor calculates the target temperature according to a preset algorithm and sends a control signal to the water temperature regulating device. The water temperature regulating device adjusts the water temperature according to the received control signal. The distance detection device can be a distance measuring sensor such as an ultrasonic sensor, an infrared sensor, etc. The distance detection device, the hot and cold water mixing valve and the processor are connected through wireless transmission.

[0161] like Figure 12 As shown, the working process of the water heater system includes:

[0162] The distance detection device detects the distance d between the human body and the sprinkler nozzle in real time, and the temperature detection device collects and feeds back the current water outlet temperature T_current of the water outlet component in real time.

[0163] After receiving the distance d, the processor determines whether the user is currently showering based on the data. If dmin ≤ d ≤ dmax, the user is deemed to be showering. Otherwise, the system checks whether the distance detection device is faulty or the sensor is submerged in water. If these conditions are met, the system automatically switches to manual mode. If the distance detection device is not faulty, the user is deemed to have left the room. If the user remains absent for 5 consecutive minutes, the system automatically enters standby mode.

[0164] When the user is showering, a target temperature T_target is calculated based on a preset algorithm based on actual operating data, for example, using the linear relationship T_target = T0 + k*(d-d0), where T0 is the reference temperature, d0 is the reference distance, and k is the temperature adjustment coefficient.

[0165] If the target temperature T_target is equal to the current outlet water temperature T_current, no processing is required. If the target temperature T_target is not equal to the current outlet water temperature T_current, then if the target temperature T_target>T_Setting, T_Setting is the water heater setting temperature, then the water heater setting temperature is increased to the target temperature T_target, and the processor mobilizes the heating component to heat the hot water. And the hot and cold water valves are turned forward to 0 opening, and full hot water is output. And the current outlet water temperature T_current and distance d are detected in real time, and adjusted in real time until T_target≤T_current. If T_target≤T_current, the proportional (P), integral (I), and differential (D) parameters of the PID algorithm are adjusted. For example, the water temperature compensation temperature ΔT can be calculated: ΔT=Kp*(T_target-T_current)+Ki∫(T_target-T_current)dt+Kdd(T_target-T_current) / dt)

[0166] Afterwards, according to the corresponding table of actual operation data, the hot and cold water mixing valve opening compensation budget method is fitted, for example, the opening compensation number ΔN is calculated using the direct proportional relationship ΔN=k0*ΔT, where k0 is the compensation adjustment coefficient.

[0167] If ΔN>0, the processor controls the hot and cold water mixing valve to rotate forward (increase the proportion of hot water output), otherwise the processor controls the hot and cold water mixing valve to rotate backward (reduce the proportion of hot water output).

[0168] According to the above embodiment, as long as the user turns on the water to take a shower, the water temperature can be adjusted in real time, thereby achieving the purpose of automatically adjusting the water temperature, improving user comfort, improving safety and energy saving.
