[0035] A hot water tank temperature sensor 8 is installed in the hot water tank 4. The intelligent heating control module 15 is controlled and connected to the hot water tank temperature sensor 8. The hot water tank temperature sensor 8 is fixed under the hot water tank 4 by insertion. Its sensor probe is close to the end of the water outlet pipe 6 and is used to monitor the hot water temperature in the hot water tank 4 in real time.

[0036] An outlet water temperature sensor 12 is installed on the outlet water pipe 6 between the outlet water solenoid valve 13 and the instant heating component 11 , and the intelligent heating control module 15 is control-connected to the outlet water temperature sensor 12 .

[0037] The intelligent heating control module 15 is connected to the hot water button 14, and the hot water tank 4 is provided with an insulation layer 3 in the interlayer. The hot water tank 4 is wrapped with a fireproof foam insulation layer 3, which can effectively reduce the heat loss of the hot water tank 4 and reduce energy consumption. The hot water tank 4 is made of 304 stainless steel material and is used to store hot water.

[0038] The low water level sensor 7 , the middle water level sensor 9 and the high water level sensor 10 are fixed to the side of the hot water tank 4 by insertion, and are used to monitor the liquid level of the hot water in the hot water tank 4 .

[0039] In this embodiment, refer to Figure 3That is, the heating component 11 includes a shell 111 and a power board 112, a water pump 113 and a heating body 114 installed in the shell 111, the power board 112 is electrically connected to the water pump 113, and the intelligent heating control module 15 is electrically connected to the power board 112; a water pump inlet is provided at one end of the water pump 113, the water pump inlet is connected to the water outlet pipe 6, the water outlet of the water pump 113 is connected to the water inlet of the heating body 114 through the water inlet connecting pipe 115, and the water outlet of the heating body 114 is connected to the water outlet pipe 6.

[0040] Reference Figure 4 The water inlet end 1141 of the heating body 114 is connected to the water outlet of the water pump 113 through the water inlet connecting pipe 115, and the water outlet end 1142 of the heating body 114 is connected to the water outlet pipe 6. A pulling tube 1143 is arranged in the heating body 114. In the present embodiment, the pulling tube 1143 is a hexagonal aluminum tube. Three stainless steel nano-electric heating tubes 1144 are installed in the pulling tube 1143. The stainless steel nano-electric heating tubes 1144 are electrically connected to the power board 112.

[0041] After being put into use, the intelligent heating control module 15 will automatically collect the trigger frequency of the hot water button 14 and automatically store the data for one week, which will be continuously covered in a cycle. Figure 2 As shown, according to logical judgment, if the frequency of water extraction is high at night from Monday to Friday, and water extraction events occur all day on weekends, it is judged as a household scenario; if the frequency of water extraction is high during the day from Monday to Friday, and no water extraction events occur all day on weekends, it is judged as a commercial scenario. The subsequent control program is selected and executed according to the determined usage scenario.

[0042] In a commercial scenario, the intelligent heating control module 15 will control the heating module 5: stop heating from the time of the last water extraction event on the same day of the previous week that is automatically stored (the default for the first use is 20:00 on the same day) to 30 minutes before the earliest water extraction event on the next day of the previous week that is automatically stored (the default for the first use is 8:00 on the next day), and during this time period, if a water extraction signal is detected by the hot water button 14, an instruction is issued to start the instant heating component 11 to supply hot water; perform normal heating from 30 minutes before the earliest water extraction event on the next day of the previous week that is automatically stored (the default for the first use is 8:00 on the next day) to the time of the last water extraction event on the same day of the previous week that is automatically stored (the default for the first use is 20:00 on the same day), and during this time period, the intelligent heating control module 15 will monitor the data of the hot water tank temperature sensor 8 in real time, control the intermittent heating of the heating module 5, and keep the hot water temperature above 90°C. Once the hot water button 14 sends a trigger signal, the intelligent heating control module 15 will control the water outlet solenoid valve 13 to open to provide hot water to the user. Since there is no water extraction event during weekends and holidays, the heating module 5 stops heating by default, and hot water is provided by the instant heating component 11 during this period.

[0043] In the home scenario, the intelligent heating control module 15 will control the heating module 5: stop heating from the time of the last water extraction event of the previous day last week that is automatically stored (the default for the first use is 00:00 on the same day) to 30 minutes before the earliest water extraction event of the same day last week that is automatically stored (the default for the first use is 17:00 on the same day), and during this time period, if a water extraction signal is detected by the hot water button 14, an instruction is issued to start the instant heating component 11 to supply hot water; perform normal heating from 30 minutes before the earliest water extraction event of the same day last week that is automatically stored (the default for the first use is 17:00 on the same day) to the time of the last water extraction event of the same day last week that is automatically stored (the default for the first use is 24:00 on the same day), and during this time period, the intelligent heating control module 15 will monitor the data of the hot water tank temperature sensor 8 in real time, control the intermittent heating of the heating module 5, and keep the hot water temperature above 90°C. Once the hot water button 14 sends a trigger signal, the intelligent heating control module 15 will control the water outlet solenoid valve 13 to open to provide hot water to the user. The above is the control logic during weekdays. The control logic during weekends and holidays is the same as that during weekdays in commercial mode.

[0044] During use, when it is detected that the water level in the hot water tank 4 is lower than the middle water level sensor 9, the intelligent heating control module 15 starts to control the water inlet solenoid valve 2 to open, and water enters the hot water tank 4 through the water inlet pipe 1. When the water level reaches the high water level sensor 10, the intelligent heating control module 15 controls the water inlet solenoid valve 2 to close and stop replenishing water. When it is detected that the water level in the hot water tank 4 is lower than the low water level sensor 7, the intelligent heating control module 15 starts to control the water outlet solenoid valve 13 to be in a normally closed state to avoid water discharge until the water level is replenished to the middle water level sensor 9. When the water replenishment reaches a certain amount, the hot water tank temperature sensor 8 detects that the water temperature is lower than 90°C, and the intelligent heating control module 15 will turn on the instant heating component 11 to reheat the outlet water to ensure that the water temperature detected by the outlet water temperature sensor 12 exceeds 90°C.

[0045] The implementation principle of the utility model is: the utility model discloses an intelligent heating device, which can meet temporary hot water needs by introducing the functional module of the instant heating component 11, ensure real-time hot water supply around the clock, take into account user experience, and overcome the thousands of boiling water phenomenon and energy waste problems that are easily formed in existing water purifiers.

[0046] It can automatically record the frequency and number of times the user draws hot water, summarize the regularity of the data for a week, select the corresponding intelligent heating control logic program, and execute it accordingly. It continuously maintains dynamic monitoring and automatic adjustment to effectively reduce the number of heating times of the water purifier. During the actual test, due to different usage scenarios and water extraction frequencies, compared with the traditional circulation heating method, it saves about 30-60% of electricity.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
