Fig. 1 is a flow chart of a method for intelligently adjusting water temperature control according to an embodiment of the present invention.

Detailed ways

In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

This embodiment provides an intelligently adjusted water temperature control method, as shown in Figure 1, including:

Step S1, obtaining the body surface temperature and ambient temperature;

Specifically, before the user turns on the water heater, that is, before the water comes out, the human body surface temperature is obtained, and the obtained human body surface temperature is transmitted to the control unit; the ambient temperature refers to the ambient temperature where the water heater is located, generally refers to the indoor temperature;

Step S2, determining the absolute value of the temperature difference between the body surface temperature of the human body and the ambient temperature;

Specifically, the body surface temperature of the human body is sometimes higher than the ambient temperature value, and sometimes lower than the ambient temperature value. This application calculates the temperature difference between the human body surface temperature and the ambient temperature by calculating the absolute value of the temperature difference between the human body surface temperature and the ambient temperature ;

Step S3, controlling the outlet water temperature to be the initial preset temperature according to the obtained human body surface temperature, or controlling the outlet water temperature to be the initial preset temperature according to the human body surface temperature and the ambient temperature;

Specifically, when a person takes a bath, the feeling of water temperature is mostly related to the temperature of the body surface of the human body, especially when the human body just contacts the water from the water heater. Generally speaking, the difference between the water temperature and the surface temperature of the human body is small, and the higher the comfort of the human body, the higher the comfort of the water temperature. When the temperature is low, the outlet water temperature should not be too low; when the ambient temperature is high, the outlet water temperature should not be too high;

Step S4, according to the absolute value of the temperature difference, obtain the temperature adjustment rate corresponding to the absolute value of the temperature difference, and adjust the outlet water temperature from the initial preset temperature to the final preset temperature according to the temperature adjustment rate;

Specifically, when the human body comes into contact with the outlet water, if the temperature difference with the environment is large, as the contact time with the outlet water increases, the human body will gradually feel hot or cold, and the temperature of the outlet water needs to be adjusted;

In this step, the temperature adjustment rate corresponding to the absolute value of the temperature difference recorded in the control unit is obtained through the absolute value of the temperature difference, and the temperature of the outlet water is adjusted according to the temperature adjustment rate, and finally adjusted to the final preset temperature.

The intelligently adjusted water temperature control method of the present invention selects the outlet water temperature most suitable for the human body through the temperature of the human body surface and the ambient temperature, and automatically adjusts the outlet water temperature to a temperature suitable for human body contact without overheating or overcooling. Improve the user's living comfort; and save the user the long process of adjusting the water temperature, improve the user's quality of life, and avoid the waste of water and electricity, energy saving and environmental protection.

On the basis of the above embodiments, this embodiment provides a specific implementation method for controlling the outlet water temperature to an initial preset temperature according to the body surface temperature of the human body, including:

According to the first preset body surface temperature range in which the body surface temperature of the human body falls, the initial preset temperature value corresponding to the first preset body surface temperature range is obtained, and the outlet water temperature is controlled to be the initial preset temperature. temperature.

Store a plurality of first preset body surface temperature intervals in the storage unit, there may be multiple first preset body surface temperature intervals, preferably in the range of 4 to 8; different first preset body surface temperature intervals Corresponding to different initial preset temperatures, specifically, the corresponding relationship between the first preset body surface temperature range and the initial preset temperature is shown in Table 1 below:

Table 1. Comparison table between the first preset body surface temperature range and the initial preset temperature

It should be noted that the higher the minimum temperature value of the first preset body surface temperature range, the higher the initial preset temperature. The initial preset temperature refers to the temperature when the user just turns on the water valve and the water heater just comes out.

When the body surface temperature of the human body is between 20°C and 30°C (including 20°C and 30°C), the corresponding initial preset temperature is between 21°C and 23°C (including 21°C and 23°C), preferably 22°C. ℃;

When the body surface temperature of the human body is between 30°C and 33°C (excluding 30°C, including 33°C), the corresponding initial preset temperature is between 23°C and 25°C (excluding 23°C, including 25°C). Preferably 24°C;

When the body surface temperature of the human body is between 33°C and 36°C (excluding 33°C, including 36°C), the corresponding initial preset temperature is between 25°C and 28°C (excluding 25°C, including 28°C). Preferably 27°C;

When the body surface temperature of the human body is between 36°C and 39°C (excluding 36°C, including 39°C), the corresponding initial preset temperature is between 28°C and 30°C (excluding 28°C, including 30°C). Preferably 29°C;

When the body surface temperature of the human body is between 39°C and 50°C (excluding 39°C, including 50°C), the corresponding initial preset temperature is between 30°C and 32°C (excluding 30°C, including 32°C). Well 31°C.

For example, when the acquired body surface temperature is 37°C, the outlet water temperature is controlled to be 29°C; when the body surface temperature is 39.1°C, the outlet water temperature is controlled to be 31°C.

In this embodiment, the preset body surface temperature intervals can be divided into multiple preset body surface temperature intervals according to actual needs, and the more the preset body surface temperature intervals are divided, the finer the control over the initial preset temperature is. In this embodiment, the preset body surface temperature is divided into 5 intervals, corresponding to 5 different initial preset temperatures. The higher the body surface temperature, the higher the initial preset temperature, and it is controlled within a reasonable range. It has better experience comfort when in contact with water, and will not cause skin damage due to overheating or overcooling, and users do not need to spend too much time adjusting the water temperature.

Optionally, this embodiment also provides a specific implementation method for controlling the outlet water temperature to an initial preset temperature according to the body surface temperature of the human body and the ambient temperature, including:

According to the second preset body surface temperature range in which the human body surface temperature and the ambient temperature fall together, the initial preset temperature value corresponding to the second preset body surface temperature range is obtained, and the outlet water temperature is controlled to be The initial preset temperature.

A plurality of second preset body surface temperature intervals are stored in the storage unit, there may be multiple second preset body surface temperature intervals, and the second preset body surface temperature intervals correspond to different body surface temperature values and ambient temperatures, different The second preset body surface temperature range corresponds to different initial preset temperatures. Specifically, the corresponding relationship between the second preset body surface temperature range and the initial preset temperature is shown in Table 2 below:

Table 2. Comparison table between the second preset body surface temperature range and the initial preset temperature

It should be noted that the first row and the first grid in Table 2 are headers, the other data in the first row are ranges corresponding to different ambient temperatures, and the other data in the first column are different second preset body surface temperature ranges. Other tables are initial preset temperatures corresponding to different ambient temperatures and different preset body surface temperature intervals; as the temperature value corresponding to the second preset body surface temperature interval is higher, the initial preset temperature is higher, and in the same preset body surface temperature interval, the initial preset temperature is higher. Under the body surface temperature range, the higher the ambient temperature, the lower the initial preset temperature.

For example, when the obtained human body surface temperature is 36.5 and the ambient temperature is 15°C, control the outlet water temperature to 30.5°C; when the obtained human body surface temperature is 39.2°C and the ambient temperature is 38°C, control the outlet water temperature to 29°C .

Compared with the control method of controlling the outlet water temperature to the initial preset temperature only based on the body surface temperature of the human body, this embodiment performs combined control according to the ambient temperature, lowering the initial preset temperature when the ambient temperature is low, and lowering the initial preset temperature when the ambient temperature is low. When the temperature is high, the initial preset temperature is increased, so that users can obtain the most comfortable outlet water temperature in different ambient temperatures (that is, regions and seasons).

On the basis of the above embodiments, this embodiment also provides a specific implementation method for controlling the temperature adjustment rate of the outlet water temperature according to the absolute value of the temperature difference, and adjusting the outlet water temperature to the final preset temperature according to the temperature adjustment rate, including:

Acquiring the temperature adjustment rate corresponding to the preset temperature difference interval according to the preset temperature difference interval in which the absolute value of the temperature difference falls;

When the initial preset temperature is greater than the final preset temperature, controlling the outlet water temperature to decrease from the initial preset temperature to the final preset temperature at the temperature adjustment rate;

When the initial preset temperature is equal to the final preset temperature, controlling the outlet water temperature to be the initial preset temperature;

When the initial preset temperature is lower than the final preset temperature, the outlet water temperature is controlled to increase from the initial preset temperature to the final preset temperature at the temperature adjustment rate.

A plurality of preset temperature difference intervals are stored in the storage unit. There may be multiple preset temperature difference intervals, and different preset temperature difference intervals correspond to different temperature adjustment rates. Specifically, the preset temperature difference intervals are related to the temperature adjustment The corresponding relationship between the rates is shown in Table 3 below:

Table 3. Comparison table of preset temperature difference range and temperature adjustment rate

Preset temperature difference range (°C) [0,10] (10,20] (20,30] (30,40] (40,50] Temperature adjustment rate (℃/min) [0,0.4] (0.4,0.8] (0.8,1.2] (1.2,1.6] (1.6～2]

In this embodiment, the temperature adjustment rate is positively correlated with the minimum temperature value in the preset temperature difference interval; as the minimum temperature value in the preset temperature difference interval increases, the temperature adjustment rate increases.

For example, when the body surface temperature of the human body is 36.5°C and the ambient temperature is 18°C, the outlet water temperature is controlled to be 31°C according to the body surface temperature of the human body and the ambient temperature; The ground temperature is 27°C; the absolute value of the temperature difference between the human body surface temperature and the ambient temperature is 18.5°C, and the temperature adjustment rate is 0.7°C/min. The initial preset temperature of 31°C is higher than the final preset temperature of 27°C, so reduce the outlet water temperature at a rate of 0.7°C/min for about 6 minutes.

When there is a gap between the surface temperature of the human body and the ambient temperature, the outlet water temperature often cannot directly reach the most comfortable temperature for the user, and needs to be adjusted to reach the most comfortable final preset temperature. This embodiment controls the water outlet temperature through the absolute value of the temperature difference between the human body surface temperature and the ambient temperature, and speeds up the adjustment rate when the temperature difference is large, so that the user can not only obtain a comfortable water temperature at the initial water outlet, but also quickly reach The most comfortable water temperature.

Preferably, the method for intelligently adjusting water temperature control in this embodiment further includes: receiving a user's voice command, and controlling the outlet water temperature to increase or decrease according to the voice command. Specifically, the above-mentioned control of the initial preset temperature and the final preset temperature according to the body surface temperature and the ambient temperature is the first-level control, but when the user's needs are still not met, the voice signal sent by the user can be collected and a voice command can be generated. According to voice commands to control the increase or decrease of outlet water temperature, this is the second level control.

Voice signals such as "increase one degree", "increase two degrees", "decrease one degree", "decrease two degrees", "30 degrees Celsius" and "28 degrees Celsius" are pre-stored in the controller (the six signals are only examples Note, it does not mean that only the six signals are pre-stored), when the user feels the water temperature is colder or hotter, by calling out voices such as "raise one degree", the controller recognizes the user's voice and performs matching, and generates the matching voice signal Voice commands, and then control the water heater to increase the outlet water temperature by one degree. For example, the outlet water temperature has reached the final preset temperature of 27°C. When the user feels the water temperature is low and wants to increase it to 30°C, he can say "30°C", and the water heater will recognize the voice and generate a voice to control the outlet water temperature to 30°C command, adjust the outlet water temperature to 30°C.

Preferably, when the outlet water temperature is adjusted by voice, the temperature adjustment rate is determined according to the absolute value of the temperature difference between the body surface temperature of the human body and the ambient temperature.

Preferably, the voice command corresponding to the voice signal sent by the user is recorded, and the final preset temperature is set as the outlet water temperature controlled by the user through voice. For example, the user controls the outlet water temperature to 29°C through voice control, and the controller sets the initial preset temperature of 27°C to 29°C to achieve the optimal match for each user.
