In practical applications, the intelligent water heater 100 is connected to all water consuming devices requiring hot water, and some of the water consuming devices have internet of things communication functions, such as the first water consuming device 210 and the second water consuming device 220 in this embodiment. The controller 130 of the intelligent water heater 100 establishes a wireless communication connection with the water consumption devices with the communication function of the internet of things, so as to acquire water demand data of the water consumption devices. More simply, the water demand data includes the temperature of the hot water required. Of course, in other embodiments, other relevant information such as water usage amount and water usage time may be included. After the controller 130 obtains the water demand data, the controller can control the water temperature regulator to provide hot water with different temperatures to a plurality of different water consumption devices.
Further, in this embodiment, the intelligent water heater may further include a remote control device, and the controller is in wireless communication connection with the remote control device to control the controller through the remote control device, and acquire and display all the water demand data received by the controller.

The embodiment also provides a control method of an intelligent water heater based on the internet of things, as shown in fig. 2, the control method includes:
s1, establishing wireless communication connection between the controller and all the water using equipment so that the controller receives water using demand data of the water using equipment in real time;

According to the control method of the intelligent water heater based on the Internet of things, wireless communication connection is established between the controller and all water utilization equipment, water utilization demand data of the water utilization equipment are obtained, and then the water temperatures flowing out of the corresponding water outlet pipes are respectively adjusted according to different water utilization demand data, so that hot water with required temperatures can be provided for each water utilization equipment at the same time, and the problem that the existing water heater cannot meet the requirement of supplying hot water with different water temperatures of multiple devices at the same time is solved.
The following describes in detail the implementation process of the control method provided in this embodiment with reference to the structure and connection manner of the intelligent water heater shown in fig. 1.
Firstly, wireless communication connection is established between the controller and all the water using equipment, so that the controller receives water using demand data of the water using equipment in real time. The water demand data includes a desired hot water temperature. For example, in the embodiment, the first water device 210 needs hot water with a water temperature of 36 ℃, and the second water device 220 needs hot water with a water temperature of 55 ℃.
Then, the controller analyzes all the received water demand data to screen out a maximum value max (temp) of the temperature of the required hot water among all the water demand data. In the embodiment, only two water-consuming devices are connected, so that the analysis process is simple, and the maximum temperature value Max (temp) is 55 ℃. In order to implement the max (temp) screening function of the controller, a simple comparator may be added to the controller, and the function may be implemented through simple logic operation, and the specific implementation method is well known to those skilled in the art and will not be described herein again.
Next, the controller sets the heating temperature of the heater to a preset temperature that is not lower than the maximum value max (temp). For example, the preset temperature may be 60 ℃, but since the preset temperature is higher than the maximum value max (temp), all the pipes need to be adjusted in water temperature. Therefore, in this embodiment, the preset temperature is preferably the maximum value max (temp), so that the pipeline connected to the water equipment with the highest required temperature does not need to be adjusted in water temperature, and the workload of the controller is reduced.
Finally, the controller controls the corresponding water temperature regulator according to the water demand data of the water consumption equipment so as to simultaneously provide hot water with required temperature for each water consumption equipment.
Specifically, in the present embodiment, as shown in fig. 1, each of the branch outlet pipes 110 includes a cold water pipe 111 for supplying cold water and a hot water pipe 112 for supplying hot water heated by the heater; the cold water pipe 111 and the hot water pipe 112 are communicated at the ends to form a main water supply pipe 113, and the main water supply pipe 113 is connected to the water consumption equipment. A cold water valve 141 is provided in the cold water pipe 111, a hot water valve 142 is provided in the hot water pipe 112, and a temperature sensor 143 is provided in the water main pipe 113. Considering that the water consumption equipment may be far away from the intelligent water heater, the temperature sensor 143 is also propagated by wireless communication, which not only reduces the problem of short circuit of the line caused by corrosion of water flow to the line, but also reduces the problem of wiring layout.
After the water temperature regulator 140 is set, the controller 130 receives the temperature of the hot water flowing through the mains water supply pipe 113 measured by the temperature sensor 143 in real time using a wireless communication technology; and controls the cold water valve 141 to control the flow of water in the cold water pipe 111 and/or controls the hot water valve 142 to control the flow of water in the hot water pipe 112 according to the temperature of the hot water measured by the temperature sensor 143.
In this embodiment, the method for controlling the cold water valve and/or the hot water valve by the controller according to the temperature of the water measured by the temperature sensor includes: the controller compares the currently received temperature of the hot water measured by the temperature sensor with the temperature of the required hot water in the water demand data provided by the water consumer: if the temperature measured by the temperature sensor is higher than the temperature in the water demand data, opening the cold water valve and/or closing the hot water valve; if the temperature measured by the temperature sensor is lower than the temperature in the water demand data, closing the cold water valve and/or opening the hot water valve; and if the temperature measured by the temperature sensor is equal to the temperature in the water demand data, keeping the states of the cold water valve and the hot water valve unchanged. For example, when the temperature measured by the temperature sensor corresponding to the first water device 210 is 50 ℃, the measured temperature is higher than the required temperature by 36 ℃, and therefore, the controller 130 opens the angle of the cold water valve 141, so that the flow rate of the cold water is increased, thereby increasing the amount of the cold water to achieve the effect of reducing the temperature, and if the angle of the cold water valve 141 is opened to the maximum and the temperature measured by the temperature sensor 143 is still higher than 36 ℃, it is proved that the amount of the hot water is still too large, and the angle of the hot water valve 142 is closed, thereby reducing the amount of the hot water. The same applies to the case where the temperature is lower than the required temperature. And stopping the adjusting process until the temperature meets the required temperature.
In order to prevent the water flow not meeting the water temperature from being wasted, a return pipe and a control valve can be arranged at the position of the main water supply pipe 113, the hot water higher than the required temperature is returned to the hot water pipe, the hot water lower than the required temperature is returned to the cold water pipe through the detection result of the temperature sensor, and the hot water meeting the required temperature is sent to the water using equipment. More complicated is that if it is necessary to control the water flow, a water flow monitoring unit may be added, and the water valve may be adjusted by water flow monitoring. The specific implementation process is not described herein again.
In summary, the intelligent water heater based on the internet of things and the control method thereof provided by the embodiment include a water outlet pipe, a heater and a controller; the water outlet pipe comprises a multi-component water outlet pipe; each group of the branch water outlet pipes is respectively connected with one water using device, and each group of the branch water outlet pipes is provided with a water temperature regulator so as to provide hot water with required temperature for the water using device; the heater is used for heating water under the control of the controller; the controller is used for receiving water demand data of all the water using equipment by utilizing a wireless communication technology, controlling the heater to heat water according to the water demand data, and controlling all the water temperature regulators to simultaneously provide hot water with required temperature for each water using equipment.
