Specifically, a body temperature detection module is set in a wearable device such as a smart bracelet, which can collect user body temperature information, and a communication program is set in the smart bracelet, and a communication module is also set in the water heater body. The communication module of the water heater and the smart bracelet Data transmission can be carried out through wireless means such as Bluetooth communication protocol. The smart bracelet sends the user's body temperature information to the water heater, and the water heater communicates with the smart bracelet after establishing a network connection, so that the water heater can obtain the user's body temperature information.

In order to eliminate interference due to the presence of multiple smart bracelets at the same time, in the embodiment of the present invention, when the signal strength of the wearable device is greater than a preset strength, the water heater establishes a connection with the wearable device. For example, the water heater is installed in the bathroom. When the user enters the bathroom and the signal strength of the communication module of the smart bracelet, such as Bluetooth, reaches the preset strength, the water heater chooses to establish a connection with the smart bracelet with the strongest communication signal, and the signal strength A better level is required. After the water heater is connected to the wearable device, the wearable device will send the user's body temperature information to the water heater.

S2, the water heater collects indoor temperature information of the bathroom.

For example, a temperature detection module is installed on the water heater, and the indoor temperature information of the bathroom where the water heater is located is collected in real time through the temperature detection module.

S3, the water heater controls the outlet water temperature of the water heater according to the user's body temperature information and the indoor temperature information.

For example, the water heater conducts a comprehensive analysis based on user body temperature information and collected indoor temperature information, and finally obtains the hot water output temperature of the water heater. Specifically, studies have found that the comfortable range of water temperature for bathing is between 35-40°C, and the water temperature slightly higher than body temperature, such as 39°C, is the most comfortable water temperature. Excessively high water temperature will destroy the protective layer of the skin, causing the skin to lose its Pollution and bacteria resistance.

Specifically, the water heater determines the reference temperature according to the indoor temperature information, and then the water heater determines the outlet water temperature according to the reference temperature and the user's body temperature information. As a specific example, as shown in the tables shown in Figure 2 and Figure 3, the water heater obtains the user's body temperature information and indoor temperature information, first obtains the corresponding reference temperature value according to the indoor temperature information in comparison with Figure 2, and then according to the reference temperature value and the user's body temperature information Refer to Figure 3 to obtain the corresponding outlet water temperature value.

The outlet water temperature can better meet the needs of users for bathing water, and users do not need to repeatedly adjust the water heater due to weather or seasonal changes, which is more convenient.

In addition, in the embodiment of the present invention, the water heater can also obtain the corresponding user personalized setting information according to the identification of the wearable device, and control the water heater according to the personalized setting information.

Specifically, it will be described with a specific embodiment. For example, for different individual users, because different personal body temperatures have certain differences, and the feeling of hot water temperature is also different, so the water heater will automatically The hot water temperature is set according to the body temperature information and the indoor temperature information of the bathroom. For example, when the indoor temperature T1 = 25°C, and the personal body temperature T3 = 37°C, the water heater is based on the temperature range of the indoor temperature, that is, 20°C<T1≤25°C, refer to Figure 2 to obtain the corresponding reference temperature value T2 = 37°C , and then refer to FIG. 3 to obtain the corresponding outlet water temperature T4=T2+1°C according to the range of T3=37°C, ie 36°C<T1≤37°C, that is, the hot water output temperature is adjusted to 38°C. If the user feels that the water temperature is not suitable when taking a bath, he will manually adjust the hot water temperature. At this time, the water heater records the hot water temperature set by the user and obtains the identification of the wearable device on the user such as MAC (Media Access Control, physical address) address. The MAC address of the wearable device is used as the unique identifier of the user, and the indoor temperature information, user body temperature information, and hot water setting temperature information are correspondingly stored as a piece of data for subsequent empirical analysis.

For another example, for the same individual, when the user enters the bathroom, the water heater uses the MAC address of the smart bracelet worn by the user as the user's unique ID to retrieve data in the database. If the smart bracelet corresponding to the MAC address is the first For the first use, the water heater will match the outlet water temperature according to the process of the above embodiment. If the data can be retrieved according to the MAC address, then compare the indoor temperature information and user body temperature information with the data corresponding to the MAC address recorded in the database. If it is consistent, the hot water temperature in the database will be directly used as the current water heater setting temperature, and when the human body temperature is high, the outlet water setting temperature will be appropriately reduced to ensure that the water heater can be customized according to the current indoor temperature information, user body temperature information and user personalization. The setting information, that is, the user's bathing habits, etc., match the most comfortable outlet water temperature.

It can be seen that in the water heater outlet temperature control method of the embodiment of the present invention, the water heater obtains the user's personalized setting information through the identification of the wearable device, and then controls the outlet water temperature according to the indoor temperature information, human body temperature information, and user's personalized setting information. , so that the hot water temperature can be automatically matched according to different members of the family, and the bathing needs of each member of the family can be truly met. The method of the embodiment of the present invention can also match the hot water needs of individual individuals in different periods to the greatest extent according to the needs of each individual in different periods, according to the indoor ambient temperature, body temperature in different periods, and bathing habits, so as to provide users with a comfortable Bathing process.
