Example 1
Fig. 1 shows a specific embodiment of a water temperature control method for a water heater, which includes:
step S101: acquiring a set water temperature value;
step S103: acquiring identity information of a user when the water heater is used for the first time, wherein the identity information of the user when the water heater is used for the first time is first identity information;
step S105: matching the first identity information with a set temperature setting value;
step S107: acquiring identity information of a user when the water heater is reused, wherein the identity information of the user is second identity information when the water heater is reused;
step S109: and when the second identity information is matched with the first identity information, controlling the water heater to discharge water at the temperature of the set water temperature.
In the water temperature control method of the water heater, the first identity information and the second identity information are named only for convenience in description, and the set water temperature value can be input in a manual mode. For example, the temperature may be set by a display panel of the water heater prior to use of the water heater, i.e., the temperature set point. And then acquiring the identity information of the user, namely the first identity information, storing the first identity information, and determining the temperature of shower outlet water of the water heater as the set temperature.
In general, a user bathes after the water is discharged from the water heater. When a user bathes at the set temperature and finishes bathing, the matching relation between the temperature set value and the first identity information is established. That is, when the water heater is reused and the second identity information is acquired, the second identity information is compared with the first identity information stored before for judgment, when the second identity information acquired by judgment is matched with the first identity information, the user can be acquiescent to be the same person, at the moment, the temperature value does not need to be manually input again, the bathing temperature does not need to be manually selected, the water heater can automatically output water according to the temperature set value according to the matching result of the second identity information matched with the first identity information, and the effect of controlling the water output temperature of the water heater according to the determined user identity without manual operation is achieved.
Further, as shown in fig. 2, the water temperature control method of the water heater further includes:
step S111: and when the water temperature data input by the user when the water heater is used is different from the set water temperature value and the second identity information is matched with the first identity information, covering the set water temperature value with the input water temperature data.
In the above steps, it is considered that the user may have different requirements for the water temperature according to the change of seasons or the change of the room temperature. For example, when the user uses the water heater again, if the user feels that the temperature is not appropriate, the temperature can be set again through the display panel of the water heater before bathing, at the moment, the obtained second identity information of the user is compared with the first identity information, the comparison result shows that the second identity information is matched with the first identity information, then the re-set temperature value can automatically cover the previously checked temperature set value to become a new temperature set value, the outlet temperature of the shower head is the re-set temperature value, and after bathing is finished, a new matching relation between the first identity information and the re-set temperature value is established, so that when the water use habit data of the user needs to be changed, the personal water use habit data can be updated only after the user needs to perform manual operation, and the flexibility and the convenience of water temperature control of the water heater are realized.
Specifically, as shown in fig. 3, matching the first identity information with the set temperature setting value specifically includes:
step S201: after the first identity information is obtained, controlling the water heater to discharge water at a water temperature set value;
step S203: and when the water heater is used, establishing a matching relation between the first identity information and the set water temperature value.
The steps are realized by controlling the water heater to discharge water at the water temperature set value for a period of time, for example, after the water heater is used for bathing, the matching relation between the first identity information and the water temperature set value is established, and a fault-tolerant time exists, so that the user cannot use the water heater after matching, and waste is avoided. For example, a user may select or input a water temperature setting value by mistake, and when the user is within the range of obtaining the identification information, the identification information of the user is automatically obtained, and the user may not be the user of the water heater.
Specifically, the identity information includes height data and weight data, and when the second identity information matches with the first identity information, specifically includes:
the height data in the second identity information is the same as the height data in one first identity information, and the second identity information is matched with the first identity information; or
The height data in the second identity information is the same as the height data in two or more first identity information, and the weight data in the second identity information is the same as the weight data in one first identity information, so that the second identity information is matched with the first identity information.
When the second identity information is judged to be matched with the first identity information, the height data is compared, and when the height data in the second identity information is the same as the height data in the previously stored first identity information, the second identity information and the first identity information can be judged to be the same user identity information, so that the second identity information can be judged to be matched with the first identity information.
And when the height data in the second identity information is the same as the height data in the two or more first identity information stored before, namely, more than two same height data exist, whether the second identity information and the first identity information belong to the same user cannot be determined only by the height, in this case, the weight data in the second identity information is compared with the weight data of the user with the same height data, when the weight data in the second identity information is the same as the weight data of one of the users with the same height data, the same user can be determined, at this moment, the matching relationship between the second identity information and the first identity information is established, and then the water heater can be controlled to discharge water at the temperature set value.
Specifically, the identity information includes height data and weight data, and as shown in fig. 4, the obtaining of the identity information specifically includes:
step S301: acquiring weight data of a user and position information of the user;
step S303: and controlling the distance measuring device 110 to measure the distance between the distance measuring device 110 and the user according to the position information, and acquiring height data through calculation.
In the step of acquiring the identity information, the distance measuring device 110 includes an infrared sensor, and the data detected by the distance measuring device 110 is a straight-line distance measured by the distance measuring device 110, as shown in fig. 5 and 6, the user stands directly on the weight measuring device 120 directly below the distance measuring device 110, that is, the user stands at the center of the weight measuring device 120. At this time, the height data of the user can be calculated according to the distance measuring formula. The ranging formula of ranging device 110 is as follows:
L＝(1/2)v×t；
where t is the time taken from emission to reception of infrared light, v is the speed of light, and v x t represents the sum of the distance from the emitting signal to the obstacle plus the distance from the obstacle back to the infrared sensor.
As shown in fig. 7, the user does not necessarily stand right under the distance measuring device 110, i.e. away from the center of the weight measuring device 120, and the user does not necessarily face the measuring plane of the distance measuring device 110. Therefore, it is necessary to acquire the position information of the user, and the user can detect the weight data only by standing on the weight measuring device 120, so that when it is detected that the user stands on the weight measuring device 120, the position information can be acquired according to the standing position of the user. For example, the load cell may detect position information of a weighed weight and obtain accurate weight data of the weight from the position information. Therefore, the measuring surface of the measuring device is controlled to face the user according to the position information of the user, so that the height data can be further calculated through the detection data.
More specifically, as shown in fig. 8, controlling the distance measuring device 110 to measure the distance between the distance measuring device 110 and the user according to the position information, and calculating to obtain the height data specifically includes:
step S401: calculating the circle center distance from the user to the center of the weight measuring device 120 according to the position information;
step S403: controlling the distance measuring device 110 to face the position of the user according to the distance between the circle centers;
step S405: controlling the location of the distance measuring device 110 to rotate on a plane formed by three points of the fixed end of the distance measuring device 110, the location of the user and the center of the weight measuring device 120;
step S407: obtaining the distance value scanned by the distance measuring device 110 in the rotation process, and when the latter distance value and the former distance value satisfy the following distance relationship, taking the former distance value as the distance from the top of the user to the distance measuring device 110:
L：L 2 >9/8L 1
in the formula, L 1 Is the previous distance value, L 2 For the latter distance value, L is the distance from the top of the user to ranging device 110;
step S409: based on the distance from the top of the user to the distance measuring device 110, height data is calculated according to the height calculation formula as follows:
in the formula, H is height data, H is the vertical distance from the distance measuring device 110 to the center of the weight measuring device 120, and R is the distance between the centers of circles;
the distance measurement formula of the distance measurement device 110 is as follows:
X＝vt；L＝(1/2)X；
in the formula, t is the time taken by the infrared sensor from the emission of infrared rays to the reception of infrared rays after encountering a user, v is the speed of light, X represents the distance traveled by the infrared sensor from the emission of infrared rays to the reception of infrared rays, and L represents the distance between the infrared rays emitted by the infrared sensor and the user.
In the above steps, X represents the sum of the distance from the infrared sensor to the obstacle from which the signal is emitted and the distance from the obstacle to the infrared sensor from which the signal is returned. Referring to fig. 7, in order to solve the problem that the measurement range of only one infrared sensor is limited, a rotating device is added, when the weighing sensor detects that a heavy object exists, the position of the heavy object, that is, the position of the user, is determined, and the circle center distance R between the user and the circle center of the weighing sensor is calculated according to the position of the heavy object. As shown in fig. 7, the rotation device moves to rotate the infrared sensor from the initial position to the front side of the infrared sensor, i.e. the measurement surface of the infrared sensor, the measurement surface faces the position of the weight, the steering engine 150 rotates at the position, and the plane on which the rotation moves is the center of the circle at the fixed end of the infrared sensor, the position of the user and the center of the circle of the weighing sensorThe plane formed by the three points. The rotary motion starts to continuously scan downwards from the circle center of the weighing sensor, and a distance value L is obtained after each scanning 1 All need to be at a later distance value L 2 By contrast, as shown in fig. 9, if: l ═ L 1 ，L 2 >9/8L 1 Then L is 1 The distance from the top of the user's head to the infrared sensor. Finally, the Pythagorean theorem is applied to pass through the formula
Height data of the user can be calculated.
More specifically, as shown in fig. 10, a flow chart of first-time water use for a user is shown, which includes the following steps:
step S501: setting water temperature;
step S503: capturing weight data and the position of a heavy object and storing the weight data and the position of the heavy object in a central processing unit;
step S505: the central processing unit controls the rotating device;
step S507: measuring the distance by an infrared sensor;
step S509: obtaining height and weight data;
step S511: storing the height and weight data to a central processor;
step S513: the shower head discharges water;
