[0002] With the development of the times and the advancement of technology, there are more and more modes available for users to choose from in their homes. Shower heads are designed with a variety of modes to meet the needs of different users. Shower modes generally include three types of water flow modes: rain, massage, and jet. Current smart shower heads generally use the temperature of the water outlet as the standard for evaluating comfort. However, the water flow rate and water droplet size vary in different modes, resulting in different temperature changes in the water during spraying. The temperature of the water in contact with the skin is different from the temperature of the water outlet.

[0003] Generally speaking, the water temperature of a household water heater is constant, but different people in the household have different requirements for the water temperature that comes into contact with their skin.

[0040] Compared with the prior art, the technical solution provided in this application has the following advantages: The server determines multiple candidate fitting curves based on the current shower head model, current indoor temperature, and the user's attribute information. Since the candidate fitting curves are related to the shower head spray mode, after the user selects the actual spray mode, the server can select a target fitting curve that matches the actual spray mode from the multiple candidate fitting curves.

This application, considering heat loss due to water droplet spraying, can control the water heater outlet temperature to vary for each user, improving the water heater's intelligence and meeting everyone's water temperature needs.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments 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.

[0051] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0052] This application provides a method for determining the outlet water temperature of a water heater, which can be applied to servers or water heaters to ensure that the outlet water temperature of a showerhead meets the water temperature requirements of each user in a household. This application takes a server as an example. Figure 1 As shown, the method includes:

[0053] Step 101: If a shower head usage command is detected, obtain the current shower head model, current indoor temperature, and attribute information of the user who wants to use the shower head.

[0054] If a user wants to use the shower, they can first turn on the shower switch. At this time, the server detects the shower usage command and can determine the user's personal information through personnel identification information. Then, it retrieves the user's attribute information from the family personnel database. The personnel identification information can be unique identifiers such as fingerprints, iris scans, or facial recognition.

[0055] The server also obtains the current indoor temperature and the current shower head model. The current indoor temperature, the current shower head model, and user attribute information are all used to select a candidate fitting curve.

[0056] Step 102: Select at least one candidate fitting curve from the preset database that matches the current shower head model, current indoor temperature, and attribute information.

[0057] Among them, the candidate fitting curve indicates the correspondence between the water outlet temperature of the water heater and the water spray temperature. Each candidate fitting curve corresponds to a shower spray mode, and the water spray temperature refers to the temperature of the water sprayed from the showerhead onto the user.

[0058] The preset database contains multiple sets of candidate fitting curves. Each set includes multiple candidate fitting curves, and each candidate fitting curve corresponds to a shower spray mode. For example, if there are three shower spray modes, then a set of candidate fitting curves would contain three candidate fitting curves.

[0059] The candidate fitting curve indicates the correspondence between the water outlet temperature of the water heater and the water shower temperature. Different shower head models have different water outlet speeds and water droplet sizes. Furthermore, the same shower head has different water outlet speeds and water droplet sizes in different modes. This means that the heat dissipation of water during the spraying process is different, and the heat dissipation is related to the current indoor temperature where the shower head is located. Therefore, the water undergoes different temperature changes during the spraying process. The temperature of the water droplets when they come into contact with the skin, which is the water shower temperature, is different from the water outlet temperature of the water heater due to heat dissipation.

[0060] Figure 2 This diagram illustrates the relationship between comfortable water flow and body surface temperature after showering. It shows that different water flow rates can cause changes in the water temperature applied to the body, resulting in differences in the final perceived temperature.

[0061] Based on this, each user has a different preferred water temperature, which is related to the user's attributes, namely height, age, or gender. Different user heights result in different water spray distances, affecting water heat dissipation. Men and women, as well as the elderly, youth, and children, have different preferred water temperatures. In other words, a user's height, age, or gender is related to their preferred shower head temperature. This is just a partial example of attribute information; other attributes related to user-preferred water temperature are also within the scope of this application.

[0062] This application can also combine the current shower head model, current indoor temperature, and any one of the user's height, age, and gender to determine the user's preferred water temperature. Figure 3 The diagram illustrates the influence of gender and season on the comfortable shower water temperature. It can be seen that the comfortable shower water temperature is higher in winter than in summer, and the comfortable shower water temperature for men is higher than that for women in summer.

[0063] Step 103: Based on the detected actual spray pattern, select the target fitting curve that matches the actual spray pattern from the candidate fitting curves.

[0064] Since each candidate fitting curve corresponds to a shower spray mode, the number of candidate fitting curves selected in step 102 is the same as the number of shower spray modes. After the user starts the shower, they need to determine the actual spray mode, and the server selects the target fitting curve that matches the actual spray mode from the candidate fitting curves.

[0065] Step 104: Determine the water outlet temperature of the water heater according to the target fitting curve based on the water shower temperature set by the user.

[0066] The target fitting curve indicates the correspondence between the water heater's outlet temperature and the water spray temperature. After the user sets the water spray temperature, the corresponding water heater outlet temperature can be determined based on this correspondence. The server then controls the water heater to dispense water at this outlet temperature, so that the water sprayed onto the user is the water spray temperature desired by the user.

[0067] In this application, the server determines multiple candidate fitting curves based on the current shower head model, current indoor temperature, and user attribute information. Since these candidate fitting curves are related to the shower head spray mode, after the user selects the actual spray mode, the server can choose a target fitting curve from the multiple candidate curves that matches the actual spray mode. Because the target fitting curve indicates the correspondence between the water heater's outlet water temperature and the shower water temperature, the controller can determine the corresponding water heater outlet water temperature based on the user-set shower water temperature, thereby controlling the water heater to dispense water at that temperature. This application, considering heat loss due to water droplet spray, can control the water heater's outlet water temperature to vary for each user, improving the water heater's intelligence and meeting the individual user's water temperature needs.

[0068] As an optional implementation, before selecting at least one candidate fitting curve that matches the current indoor temperature and attribute information from a preset database, the method further includes: acquiring shower head model information and multiple sample information, wherein each sample information includes sample spray mode, sample water outlet temperature, sample indoor temperature, and sample user attribute information; processing the model information and multiple sample information through an algorithm model to generate candidate fitting curves, wherein the algorithm model is obtained based on support vector machine training, and each candidate fitting curve is generated based on multiple similar sample information for the same shower head model and the same spray mode; and storing the correspondence between shower head model, indoor temperature, user attribute information, and candidate fitting curves in a preset database.

[0069] Since different shower head models have different numbers and sizes of water outlets, this application sets up a set of candidate fitting curves for each model of shower head. The process of generating candidate fitting curves is as follows.

[0070] The server acquires shower head model information and various sample information. Each sample includes the shower head's spray mode, water outlet temperature, indoor temperature, and user attributes (where a user is considered a single user). The server trains an algorithm model based on an SVM (Support Vector Machine) and then processes the model information and sample information. Similar sample information will generate a candidate fitting curve. Similar sample information refers to samples with the same shower mode, water outlet temperature within a set temperature range, indoor temperature within a preset temperature range, and user attributes within a common attribute range.

[0071] Specifically, the algorithm model processes the model information and various sample information to obtain candidate fitting curves, including: determining the water outlet heat dissipation efficiency based on the water outlet speed, water droplet size, and sample indoor temperature; processing the sample water outlet temperature, water outlet heat dissipation efficiency, and sample user attribute information through the algorithm model to obtain the correspondence between the water outlet temperature of the water heater and the water shower temperature; and generating candidate fitting curves based on the correspondence.

[0072] Since different showerhead models have different numbers and sizes of water outlets, the server determines the water flow rate and water droplet size of the showerhead in the sample spray mode based on the showerhead model information. Since the heat dissipation of the water droplets varies with different indoor temperatures, the server combines the water flow rate, water droplet size, and sample indoor temperature to determine the water flow heat dissipation efficiency. Finally, the algorithm model processes the sample water flow temperature, water flow heat dissipation efficiency, and attribute information of similar sample users to obtain the correspondence between the water heater's water flow temperature and the water spray temperature. Finally, a candidate fitting curve is generated based on this correspondence.

[0073] As an optional implementation, after determining the water outlet temperature of the water heater according to the target fitting curve, the method further includes: obtaining feedback information from users on the terminal, wherein the feedback information includes whether the actual water shower temperature is colder or hotter than the set water shower temperature; adjusting the target fitting curve according to the feedback information; and incorporating the adjusted target fitting curve into a preset database to replace the corresponding original candidate fitting curve.

[0074] After using the smart showerhead, users can rate it on the relevant smart home app, indicating whether the water temperature is cold or hot. The server uses this feedback to determine user satisfaction. Based on this feedback, the server adjusts the target fitting curve to meet the user's needs. The adjusted target fitting curve is then added to a preset database, replacing the original candidate fitting curves. This updates the preset database, allowing users to select the adjusted fitting curve from the database the next time they use the showerhead, ensuring the fitting curve better matches their water temperature requirements.

[0075] like Figure 4 This is a schematic diagram illustrating the process of determining the outlet water temperature of a water heater.

[0076] Furthermore, after determining the water outlet temperature of the water heater according to the target fitting curve, the method also includes: determining the season in which the water heater is used each time; and using the target fitting curve that appears most frequently in the same season as the candidate fitting curve for the next same season.

[0077] The server records the season in which the water heater is used each time, i.e., spring, summer, autumn, and winter, every three months. Then, the target fitting curve that appears most frequently in each season is taken as the most comfortable shower temperature that users are most accustomed to using. This target fitting curve is then used as the candidate fitting curve for the next year in the same season. Since the shower temperature required by the same user should not change much in the following year, this can improve the accuracy of the candidate fitting curve for the next year and improve user satisfaction.

[0078] In addition, the showerhead may become clogged with limescale. After the controller adjusts the target fitting curve, if it detects that the curvature of the adjusted target fitting curve deviates from the curvature of the corresponding initial candidate fitting curve by more than a preset threshold, such as more than 10%, it will promptly remind the user to check the condition of the showerhead or water heater, clean and resolve issues such as water flow rate and water temperature caused by limescale, and ensure the long-term stability of the product and the best user experience.

The candidate fitting curve indicates the correspondence between the water outlet temperature of the water heater and the water spray temperature. Each candidate fitting curve corresponds to a shower head spray mode. The water spray temperature refers to the temperature of the water sprayed from the shower head onto the user.

The second selection module is used to select a target fitting curve that matches the actual spraying pattern from the candidate fitting curves based on the detected actual spraying pattern. The determination module is used to determine the outlet water temperature of the water heater according to the target fitting curve based on the water shower temperature set by the user. Before selecting at least one candidate fitting curve from the preset database that matches the current indoor temperature and the attribute information, the process further includes: Obtain the model information of the shower head and various sample information, wherein each sample information includes the sample spray mode, sample water temperature, sample indoor temperature and sample user attribute information; The model information and the various sample information are processed by an algorithm model to generate candidate fitting curves. The algorithm model is based on support vector machine training, and each candidate fitting curve is generated for multiple similar sample information of the same shower head model and the same spray mode. Store the correspondence between shower head model, indoor temperature, user attribute information and candidate fitting curves in a preset database; The algorithm model processes the model information and the various sample information to obtain candidate fitting curves, including: Based on the model information of the shower head, determine the water flow rate and water droplet size of the shower head in the sample spray mode; The water dissipation efficiency is determined based on the water flow rate, the water droplet size, and the sample chamber temperature. The algorithm model is used to process the sample water outlet temperature, the water outlet heat dissipation efficiency, and the attribute information of the sample users to obtain the correspondence between the water outlet temperature of the water heater and the water shower temperature. The candidate fitting curves are generated based on the correspondence.
