The human body recognition device is used for detecting the approach of a human body and has the functions of camera imaging, ultrasonic imaging or infrared imaging. Through the human body recognition device, a user can be sensed to be close to the human body recognition device in real time, and physical sign parameters (such as height, facial imaging and the like) of the user can be recognized through a camera imaging function, an ultrasonic imaging function or an infrared imaging function of the human body recognition device. The human body recognition device can be directly arranged inside the water heater, can also be arranged outside the water heater as an independent component and is positioned near the water using end, and the human body recognition device can be used for detecting the approach of a human body and acquiring physical sign parameters.
In this embodiment, the hot water system may further include a water flow detection device, the water flow detection device may detect water flow in the circulation pipeline, and feed water flow information back to the water heater, and the water heater may perform relevant operations according to the water flow information. In this embodiment, the water heater has alarming function, and it can send alarm information to user or property center to improve the safety in utilization.
Fig. 1 shows a flowchart of a hot water circulation control method of the present embodiment, and as shown in fig. 1, the hot water circulation control method specifically includes the following steps:
s10, detecting whether a human body approaches, if so, executing a step S20; if not, go back to step S10;
in this step, when the user approaches the water heater or the water consumption end, the approach of the user can be recognized by the human body recognition device, and then step S20 can be executed; if no user approach is identified, then the loop executes step S10.
And S20, acquiring physical sign parameters of the human body.

S30, judging whether the acquired physical sign parameters of the human body are matched with the corresponding user data, if so, executing a step S40; if not, step S50 is performed.
After the physical sign parameters of the human body are obtained, the physical sign parameters of the human body are compared with pre-stored user data (the user data at least comprises height and facial imaging), and the user data corresponding to the physical sign parameters are found out. When the user data corresponding to the physical sign parameter can be found, executing step S40; if the corresponding user data is not matched, it indicates that the user is not a person who uses hot water on a daily basis, or the person information is not entered in the pre-stored user data, and then step S50 is executed.
In this embodiment, further, since the physical parameters include height and facial imaging, there are the following cases for the user data matched to the physical parameters:
1. only through the height parameter, with the user data contrast that prestores, only have one user data that corresponds to the height parameter this moment, then need not to use facial imaging to continue to match corresponding user data. That is, the physical parameters of the human body obtained at this time correspond to and only have one user data, and step S40 is directly executed.
2. Only the facial imaging parameters are compared with the pre-stored user data, only one user data corresponding to the facial imaging parameters exists at the moment, and the corresponding user data is continuously matched without using the height. That is, the physical parameters of the human body obtained at this time correspond to and only have one user data, and step S40 is directly executed.
3. After the height parameters are compared with the pre-stored user data, a plurality of user data corresponding to the height parameters exist (namely the heights of a plurality of users are the same or similar, the height parameters can correspond to the plurality of user data), the user data are required to be matched and compared with the corresponding user data again through facial imaging, and at the moment, whether the corresponding user data can be matched or not is determined through the facial imaging parameters. If the corresponding user data can be matched, directly executing step S40; if the facial imaging parameters still do not match the corresponding user data, step S50 is performed.
4. After the facial imaging parameters are compared with the pre-stored user data, a plurality of user data corresponding to the facial imaging parameters exist (namely facial imaging of a plurality of users is possible to be similar, the facial imaging parameters correspond to the plurality of user data), matching and comparison with the plurality of corresponding user data again need to be carried out through the height parameters, and at the moment, whether the corresponding user data can be matched or not can be determined through the height parameters. If the corresponding user data can be matched, directly executing step S40; if the height parameters still do not match the corresponding user data, step S50 is performed.
And S40, starting hot water circulation for a preset time.
After the corresponding user data are matched, the probability that the user uses hot water at the moment is very high, therefore, hot water circulation is started, the circulation pipeline is filled with hot water, and the circulation is stopped after the hot water circulation is carried out for the preset time, so that energy waste is avoided.
And S50, not starting hot water circulation.
That is, when the corresponding user data is not matched, it indicates that the user does not use hot water, and the hot water circulation is not started.
It should be noted that, in this embodiment, except that the human body detection device is used to detect a human body and obtain characteristic parameters of the human body, the other control processes may be completed by a control system of the water heater (prior art, which is not described herein).
According to the hot water circulation control method, the detected physical sign parameters of the human body are acquired, then the physical sign parameters are matched with the acquired physical sign parameters according to the pre-stored user data, and when the physical sign parameters of the human body are matched with the corresponding user data, hot water circulation is started for preset time; and when the physical sign parameters of the human body are not matched with the corresponding user data, the hot water circulation is not started. The instant hot water use of the user can be intelligently realized, the convenience is improved, and the energy waste is avoided.

And S70, not starting hot water circulation.
Compared with the first embodiment, the hot water circulation control method of the present embodiment adds step S50, that is, when the corresponding user data is matched, it is further determined whether the current time is the common water consumption time of the user corresponding to the user data, and if so, the hot water circulation preset time may be directly started; if not, the user probably does not want to use the hot water, and the hot water circulation is not started, so that the intelligent degree is further improved, and the energy is saved.
Example four
The difference between this embodiment and the third embodiment is that the present embodiment performs the water leakage detection operation when no human body is detected to approach, specifically, as shown in fig. 4, the hot water circulation control method of this embodiment includes the following steps:

S80, detecting whether the water flow in the circulating pipeline exceeds a preset flow value, if so, executing a step S90; if not, return is made to step S10.
And S90, closing the waterway main valve.
That is to say, when the embodiment detects that the water flow rate in the circulation pipeline exceeds the preset flow rate value, and the user does not use hot water at this time, it indicates that the water leakage condition exists in the current circulation pipeline, and at this time, for the safety of the user, the water heater can control to close the main water path valve, so as to avoid the water leakage condition from becoming more serious.
Furthermore, after the water way main valve is closed, the alarm can be given through the water heater, and at the moment, the water heater can send alarm information to a mobile terminal used by a user or a property center to remind the user of water leakage and to timely treat the water leakage.
