[0002] With the popularization and application of smart home appliance technology, users' requirements for the intelligence of water heaters have reached a new level. Modern families are no longer satisfied with basic hot water supply, but pursue a more convenient and comfortable bathing experience. Currently, when users use water heaters for showering, they usually set a water temperature for the water heater. The heated water is then transported to the showerhead through pipes. When the user turns on the showerhead, the hot water is sprayed evenly through the showerhead nozzles, forming a bathing water flow.

[0003] However, modern bathrooms typically have multiple showerheads. When users switch between different showerheads or use different methods with the same showerhead, the perceived temperature changes accordingly, requiring frequent water temperature adjustments and resulting in a poor user experience. Summary of the Invention

[0048] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0051] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0052] Modern bathrooms typically have multiple showerheads, such as overhead showerheads and handheld showerheads. The type and method of using these showerheads can affect the perceived temperature. For example, the temperature might be just right when using a handheld showerhead, but once the handheld showerhead is fixed in place, or when switching to an overhead showerhead, the water might feel cold, requiring readjustment of the water temperature and resulting in a less than ideal showering experience.

[0053] To address the aforementioned issues, this application provides a water heater control method. When a user prepares to shower, the system responds to the user's voice command, recognizes the command to determine the user and their target perceived temperature, and then uses a distance sensor on the showerhead to detect the real-time distance between the showerhead and the user's body. This real-time distance parameter is transmitted to the water heater's control system, allowing the system to calculate the water outlet temperature based on the user's target perceived temperature and the distance parameter. This ensures the user's perceived temperature reaches their target temperature, automatically adjusting the water outlet temperature. This method satisfies the user's perceived temperature needs when switching showerheads or using different shower methods, without requiring manual temperature adjustment, making the showering process more comfortable and convenient, and improving the user experience.

[0054] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0055] Figure 1 A flowchart illustrating the water heater control method provided in this application embodiment. Figure 1 In this embodiment, the executing entity is, for example, the control system of a water heater. Figure 1 As shown, the water heater control method provided in this embodiment includes:

[0056] S101, Detects the real-time distance between the shower head and the user.

[0057] The distance between the showerhead and the user can be detected by a distance sensor on the showerhead. This real-time distance is used to indicate the difference in water outlet height. The distance sensor can be, for example, an infrared distance sensor or an ultrasonic sensor. The showerhead refers to the showerhead currently being used by the user. The showerhead type can be, for example, a handheld showerhead, a fixed showerhead, an overhead showerhead, a digital showerhead, or a folding showerhead. The number of showerheads can be one or more. This application does not impose any special restrictions on the type and number of showerheads.

[0058] Understandably, when a user stands under the showerhead to shower, the distance sensor can detect multiple distance parameters between the showerhead and the user's body. By analyzing and processing these distance parameters, some false parameters can be eliminated, and the distance parameters between the showerhead and the main area of ​​the user's body can be determined. These distance parameters are then used as the real-time distance between the showerhead and the user.

[0059] S103. Determine the outlet water temperature of the water heater based on the target perceived temperature and real-time distance.

[0060] The target perceived temperature can be a preset perceived temperature under unknown user water usage habits, or it can be a perceived temperature determined after user identification.

[0061] If the user is not identified or the user identification fails, it means that the user's water usage habits are unknown at this time, and the preset perceived temperature can be used as the target perceived temperature.

[0062] If the user is successfully identified, the user's perceived temperature can be obtained as the target perceived temperature.

[0063] Here, the methods for user identification can include, for example, voice recognition, facial recognition, fingerprint recognition, etc. This application does not impose any special restrictions on this.

[0064] For example, when a user speaks to the water heater before taking a shower, such as "I want to take a shower," the voice module captures the user's voice command, extracts the voiceprint features of the voice signal in real time, compares them with the voiceprint models in the database, and then uses a matching algorithm to calculate the similarity between the voice signal and the existing voiceprint models, thereby determining the user to whom the voice command belongs, and further determining the target body temperature corresponding to that user.

[0065] Here, with the water heater connected to the cloud server and smart terminal, the user can set the perceived temperature value corresponding to their own voiceprint model through the application on the smart terminal. After setting, the smart terminal sends the voiceprint model and the perceived temperature value corresponding to the voiceprint model to the cloud server, and then sends it to the water heater through the cloud server. In this way, each voiceprint feature of the water heater corresponds to the user and the most suitable perceived temperature for that user.

[0066] The showerhead can send real-time distance data to the water heater via an infrared communication module. Based on this real-time distance, the water heater can determine the water outlet height difference and calculate the actual perceived temperature of the hot water after it falls from the showerhead onto the user, according to the relationship between the current water temperature, the water outlet height difference, and the perceived temperature. Then, it compares this actual perceived temperature with the target perceived temperature to determine whether the water temperature needs to be adjusted.

[0067] When it is necessary to adjust the water temperature, the target water temperature of the water heater is calculated based on the correspondence between the target perceived temperature, the real-time distance, and the water temperature. This allows the water heater to be controlled to dispense water at the target temperature, ensuring that the user's perceived temperature needs can be met regardless of which shower head the user uses, whether it is a handheld shower head or a fixed shower head.

[0068] For example, when a user holds the showerhead in their hand, the temperature difference is small due to the short distance between the water droplets and the water, so the water temperature from the water heater is close to the target perceived temperature. When a user fixes the showerhead in place or uses the top showerhead, the temperature difference is greater due to the greater distance between the water droplets. The water heater will determine the water temperature based on the real-time distance transmitted by the showerhead and the user's target perceived temperature, and automatically raise the water temperature to that temperature.

[0069] Optionally, the water heater can also send the real-time distance to a cloud server, where the optimal outlet water temperature is calculated based on the real-time distance and the target perceived temperature.

[0070] It should be noted that the water heater control method provided in this application embodiment can be applied to any type of water heater, such as instant water heater, storage water heater, air source water heater, electric water heater, gas water heater, etc.

[0071] The water heater control method provided in this application detects the real-time distance between the showerhead and the user, and determines the water outlet temperature of the water heater based on the target perceived temperature and the real-time distance. This method automatically determines the water outlet temperature of the water heater based on the real-time distance between the showerhead and the user, ensuring that the user's perceived temperature reaches their target perceived temperature when switching between different showerheads or using different methods of showering, without requiring the user to manually adjust the water temperature. This makes the user's showering process more comfortable and convenient, and improves the user experience.

[0072] Figure 2 Flowchart of the water heater control method provided in this application Figure 2 ,like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, the control method for the water heater is described in detail. The control method for the water heater provided in this embodiment includes:

[0073] S201. Identify the user.

[0074] Here, user identification can be achieved through methods such as voice recognition, facial recognition, fingerprint recognition, or identification when the user wears a wristband with an RFID or NFC chip. This application does not impose any special restrictions on this.

[0075] S202. If the user is a pre-stored registered user, then the pre-stored target perceived temperature of that user is determined as the target perceived temperature.

[0076] For example, a registered user refers to a user who registers through an application on a smart terminal, inputting personal information and a target body temperature. Afterward, the user records one or more voice samples for voiceprint recognition. Voiceprint recognition algorithms extract voiceprint features from the voice samples, thereby storing the user's voiceprint features and target body temperature in a database.

[0077] Thus, when a user issues a voice command such as "I want to take a shower," the voiceprint features in the voice command are extracted and compared with the voiceprint features stored in the database to determine the user's identity and obtain the user's target body temperature from the database.

[0078] S203. If the user is an unregistered user, the preset perceived temperature will be set as the user's target perceived temperature.

[0079] For example, if a user is identified as an unregistered user after voice recognition, the pre-set perceived temperature can be set as the user's target perceived temperature.

[0080] The voiceprint recognition results include user type, such as elderly, adult, child, male, female, etc. The preset perceived temperature can be set based on various types of user voiceprint data in the database and empirical values ​​of water temperature. Different user types correspond to different preset perceived temperatures; for example, the preset perceived temperature for the elderly is 38℃, for adults it is 40℃, and for children it is 37℃.

[0081] In some embodiments, if the voiceprint recognition result indicates that the user is an unregistered user, then based on the user's user type, a preset body temperature corresponding to the user's user type is determined, and the preset body temperature is determined as the user's target body temperature.

[0082] First, define user types and their corresponding preset body temperature. Building upon voiceprint recognition, add user type recognition. User types can be determined using voiceprint features, and based on the identified user type, the corresponding body temperature is obtained from multiple preset body temperature options.

[0083] S204. A first sensor installed on the showerhead is used to detect the first distance between the showerhead and the user in real time.

[0084] The first sensor, for example, refers to an infrared sensor, and the first distance refers to the distance between the shower head and the bathing user's current body detected by the first sensor. It should be understood that when the first sensor is an infrared sensor, it can detect changes in infrared radiation in the environment. When the user enters the detection range of the infrared sensor, the infrared sensor can detect changes in infrared radiation, thereby determining whether the user's body is present.

[0085] In this step, based on the user's body shape, outline, and the user's specific position and posture under the showerhead, the first sensor on the showerhead will detect the distance parameters between the showerhead and multiple body parts of the user, namely multiple first distances.

[0086] In some embodiments, the distance from the showerhead to the bathroom floor and the distance from the showerhead to the user's head can be detected by the first sensor, thereby calculating the user's height data.

[0087] S205. Filter the multiple first distances obtained from multiple detections to obtain the real-time distance.

[0088] The real-time distance refers to the distance between the showerhead and the main area of ​​the user's body, which is the main shower area the user is currently showering, such as the head, back, and lower limbs.

[0089] Understandably, since the first distance refers to the distance parameters between the showerhead and multiple parts of the user's body, there may be misjudged parameters among these distance parameters. Misjudged parameters may cause the system to frequently perform unnecessary operations, such as incorrectly adjusting the water temperature, consuming resources and reducing the user experience. Therefore, by filtering multiple first distances, some misjudged parameters can be eliminated, and the actual distance parameters between the showerhead and the user's current main body area can be determined.

[0090] In one possible implementation, a second sensor installed on the water heater can be used to detect the second distance between the water heater and the user in real time. Based on multiple second distances obtained from multiple detections, multiple first distances are filtered to obtain the real-time distance.

[0091] The second sensor, for example, refers to an ultrasonic sensor, and the second distance refers to the distance between the shower head and the bathing user's current body detected by the second sensor.

[0092] For example, if the change values ​​of multiple second distances are less than the first threshold, and if among the multiple first distances there is a target first distance whose difference from other first distances is greater than the second threshold, then the target first distance among the multiple first distances is removed to obtain the real-time distance.

[0093] When the second sensor is an ultrasonic sensor, the ultrasonic sensor can detect the distance between the shower head and the user multiple times, obtaining multiple second distances, such as 30cm, 31cm, 33cm, and 35cm; multiple first distances, such as 30cm, 32cm, 34cm, and 44cm; a first threshold, such as 5cm, and a second threshold, such as 10cm. At this time, it can be determined that the changes in the above multiple second distances compared to the previous second distance are 1cm, 2cm, and 2cm, respectively, all less than the first threshold of 5cm, indicating that the values ​​of the second distances are relatively stable and the user has not moved significantly in the main position of the space. However, the differences between the first distance of 40cm and other first distances are 14cm, 12cm, and 10cm, respectively, all greater than the second threshold of 10cm. Thus, it can be determined that the 44cm in the first distance is a misjudged distance parameter, i.e., the target first distance, and it is discarded.

[0094] S206. Determine the distance range of the real-time distance.

[0095] When there are multiple distance parameters for real-time distance, the distance range of the set of real-time distances can be determined based on the maximum and minimum values ​​of the multiple distance parameters, thereby determining the main bathing area of ​​the user's body corresponding to the distance range.

[0096] Here, multiple distance ranges can be preset based on the height data of bathing users. This is because, when a person is standing, the height of different parts of the body relative to the ground is fixed. For example, the head height is usually around 100% of the height, and the shoulder height is about 60% of the height.

[0097] Therefore, based on the user's height data, reasonable distance thresholds can be set, and multiple distance ranges can be obtained based on these thresholds. After obtaining the real-time distance, the distance range to which the real-time distance belongs can be determined based on the user's height data. For example, if the user's height is 175cm and the shower head is 210cm above the ground, then the distance range corresponding to the user's head shower area is 25cm-35cm, and the distance range corresponding to the back shower area is 40cm-88cm.

[0098] The purpose of this step is to prevent the water heater from frequently and unnecessarily adjusting the water temperature when the distance changes slightly in real time, which would lead to unstable water temperature and affect the user experience.

[0099] S207. Determine the water outlet temperature of the water heater based on the distance range, target perceived temperature, ambient temperature, and shower head water flow rate.

[0100] Among the factors influencing the water heater's outlet temperature are the real-time distance between the showerhead and the user, the user's target perceived temperature, the ambient temperature of the bathing space, and the current water flow rate from the showerhead. For example, the greater the distance between the showerhead and the bathing area, the longer the hot water takes to physically dissipate heat in the air, resulting in a lower perceived temperature when it reaches the user's body, necessitating an increase in the water heater's outlet temperature. Conversely, the lower the ambient temperature, the faster the water cools in the air, requiring an increase in the outlet temperature to compensate for cooling losses. At the same initial outlet temperature, a smaller water flow rate from the showerhead results in slightly higher water temperatures reaching the user's body, necessitating a decrease in the outlet temperature to prevent overheating. In short, the goal is to ensure the water heater delivers water at the calculated target outlet temperature, ensuring the user's perceived temperature reaches the target temperature.

[0101] In one possible implementation, different distance ranges correspond to different target perceived temperatures. This means that for the same user when bathing different parts of the body, there can be multiple target perceived temperatures. For example, if the user is currently bathing the head based on the real-time distance range, the target perceived temperature can be 38°C; if the user is currently bathing the back based on the real-time distance range, the target perceived temperature can be 41°C.

[0102] The water heater control method provided in this application responds to voice commands by recognizing the voice commands. If the voiceprint recognition result indicates that the user is a pre-stored registered user, the method obtains the pre-stored target perceived temperature for the user. If the voiceprint recognition result indicates that the user is an unregistered user, the method determines the preset perceived temperature as the user's target perceived temperature. A first sensor installed on the showerhead detects the first distance between the showerhead and the user in real time. Multiple first distances obtained from multiple detections are filtered to obtain the real-time distance, thus improving the accuracy of determining the real-time distance between the showerhead and the user. Based on the distance range of the real-time distance, the target perceived temperature, the ambient temperature, and the water flow rate of the showerhead, the method automatically determines the water outlet temperature of the water heater to ensure that the user's real-time perceived temperature can reach their target perceived temperature, thereby improving the user experience.
