[0055] Figure 3 A flow chart of a heating control method provided by an embodiment of the present invention is as follows: Figure 3 As shown, the method includes:

[0056] Step 101: Before controlling the water dispenser to heat, if it is determined that the water dispenser gave an alarm when the water was stopped last time, the water inlet flow rate is detected by a flow meter.

[0057] Step 102: If it is determined that the water inlet flow rate is greater than the preset water inlet flow rate threshold, the water dispenser is controlled to heat according to the specified heating power.

[0058] Step 103: Detect the water inlet flow rate through a flow meter at preset time intervals.

[0059] Step 104: If it is determined that the water inlet flow rate is less than or equal to the preset water inlet flow rate threshold, the water dispenser is controlled to sound an alarm.

[0060] In the technical solution provided by the embodiment of the present invention, before controlling the water dispenser to heat, if it is determined that the water dispenser alarmed when water was stopped last time, the water inlet flow rate is detected by a flow meter; if it is determined that the water inlet flow rate is greater than a preset water inlet flow rate threshold, the water dispenser is controlled to heat according to a specified heating power; the water inlet flow rate is detected by a flow meter at a preset time interval; if it is determined that the water inlet flow rate is less than or equal to the preset water inlet flow rate threshold, the water dispenser is controlled to alarm, thereby improving the safety performance of the water dispenser.

[0061] Figure 4 A flow chart of another heating control method provided by an embodiment of the present invention is as follows: Figure 4 As shown, the method includes:

[0062] Step 201 , determine whether the water dispenser sounded an alarm when it stopped dispensing water last time. If so, execute step 202 ; if not, execute step 204 .

[0063] In the embodiment of the present invention, each step is executed by the control board.

[0064] In the embodiment of the present invention, if it is determined that the water dispenser alarmed when the water supply stopped last time, it indicates that the water path is short of water and heating cannot be performed, and step 202 is continued; if it is determined that the water dispenser did not alarm when the water supply stopped last time, it indicates that the water path is not short of water and heating can be performed directly, and step 204 is continued.

[0065] Step 202: Detect the water inlet flow rate through a flow meter.

[0066] In the embodiment of the present invention, water flows into the waterway through the water inlet, and the flow meter can detect the inlet water flow rate.

[0067] Step 203 , determine whether the water inlet flow rate is greater than a preset water inlet flow rate threshold. If so, execute step 204 ; if not, execute step 202 .

[0068] In the embodiment of the present application, the water inlet flow rate threshold value can be set according to system performance and / or implementation requirements, etc. during implementation, and the embodiment does not limit the size of the water inlet flow rate threshold value.

[0069] In the embodiment of the present application, if it is judged that the water inlet flow rate is greater than the preset water inlet flow rate threshold value, it indicates that the waterway was in a water state when the last water outlet was completed, and heating can be performed, and step 204 is continued to execute. If it is judged that the water inlet flow rate is less than or equal to the preset water inlet flow rate threshold value, it indicates that the waterway was in a water shortage state when the last water outlet was completed, and the heating tube cannot be controlled to perform heating at this time, and the water inlet flow rate needs to be continuously monitored until the water inlet flow rate is greater than the preset water inlet flow rate threshold value, and step 202 is continued to execute.

[0070] In the embodiment of the present application, before the heating tube is controlled to perform heating, the user starts the water pump to inlet water by pressing the water outlet button, and whether the water dispenser alarms when the last water outlet is stopped is judged, so as to judge whether the waterway was in a water shortage state or a water state when the last water outlet was completed. If the waterway is in a water state, direct heating according to the specified heating power is performed. In actual application, among the number of uses from when the water tank is filled with water to when the waterway is detected to be in a water shortage state, except that the first water outlet needs to be heated after the water is detected, the subsequent water outlet can be directly heated because the waterway is full of water, so as to save time and achieve the purpose of instant heating and fast hot water outlet. If the waterway is in a water shortage state, the water inlet flow rate needs to be continuously monitored until the water inlet flow rate is greater than the preset water inlet flow rate threshold value, that is, the waterway is in a water state, and then the heating tube is controlled to perform heating, so as to ensure that the waterway has water when the heating tube performs heating, prevent the heating tube from being dry-burned due to water shortage, and thus the service life of the heating tube can be prolonged.

[0071] Step 204: Obtain the water inlet temperature and the preset water outlet temperature threshold value.

[0072] In the embodiment of the present application, the water inlet temperature can be detected by a water inlet sensor.

[0073] In the embodiment of the present application, the water outlet temperature threshold value can be set according to system performance and / or implementation requirements, etc. during implementation, and the embodiment does not limit the size of the water outlet temperature threshold value. As an optional solution, since the water dispenser itself is difficult to judge whether it is currently in a plateau state, the highest water outlet temperature can be set to 95℃, the controllable water outlet temperature range of the water dispenser is greater than or equal to 93 degrees Celsius (℃) and less than or equal to 97℃, and therefore the water outlet temperature threshold value can be set to be slightly higher than the controllable water outlet temperature range, for example, the water outlet temperature threshold value is 98℃, 99℃ or 100℃.

[0074] Step 205: Query the specified heating power according to the water inlet temperature and the water outlet temperature threshold value.

[0075] In the embodiment of the present invention, a correspondence between the inlet water temperature and outlet water temperature thresholds and the heating power is preset, and the corresponding heating power can be queried according to the inlet water temperature and outlet water temperature thresholds.

[0076] Step 206: Control the water dispenser to heat according to the specified heating power.

[0077] In the embodiment of the present invention, the control board controls the heating tube of the water dispenser to heat the water flowing through the heating tube according to the specified heating power.

[0078] Furthermore, in response to the user pressing the stop button, the water pump stops supplying water, the heating pipe stops heating, and the water outlet stops discharging water.

[0079] Step 207: Detect the water inlet flow rate through a flow meter at preset time intervals.

[0080] In the embodiment of the present invention, the preset time interval can be set according to system performance and / or implementation requirements during specific implementation, so as to detect the water inlet flow rate in real time during the heating process.

[0081] Step 208 , determine whether the water inlet flow rate is less than or equal to a preset water inlet flow rate threshold. If so, execute step 209 ; if not, execute step 212 .

[0082] In the embodiment of the present invention, the water inlet flow rate threshold value can be set according to system performance and / or implementation requirements during specific implementation. This embodiment does not limit the size of the water inlet flow rate threshold value.

[0083] In an embodiment of the present invention, if it is determined that the water inlet flow rate is less than or equal to the water inlet flow rate threshold, it indicates that the water channel is in a water-scarce state during the heating process, and heating cannot continue, and step 209 is continued; if it is determined that the water inlet flow rate is greater than the water inlet flow rate threshold, it indicates that the water channel is in a water-filled state during the heating process, and heating can continue, and step 212 is continued.

[0084] In an embodiment of the present invention, during the heating process of the heating tube, the water inlet flow rate is detected in real time by a flow meter. When the water inlet flow rate is less than or equal to the water inlet flow rate threshold, it indicates that the water path is in a water shortage state, and an alarm is required to stop the water discharge and heating to prevent the heating tube from burning dry.

[0085] Step 209: Control the water dispenser to sound an alarm.

[0086] In the embodiment of the present invention, if it is determined that the water outlet is short of water, the control panel controls the water dispenser to sound an alarm to remind the user that the water dispenser is currently faulty and cannot continue to heat and dispense water.

[0087] As an optional solution, the alarm mode is that the control panel controls the buzzer of the water dispenser to sound, which can effectively improve the user experience. The alarm can also be performed in other ways, and the embodiment of the present invention does not limit the alarm mode.

[0088] Step 210: Control the water dispenser to stop heating.

[0089] In the embodiment of the present invention, the control board controls the heating tube of the water dispenser to stop heating.

[0090] Step 211: Control the water dispenser to stop discharging water, and the process ends.

[0091] In the embodiment of the present invention, the control panel controls the water outlet of the water dispenser to stop discharging water, and the process ends.

[0092] Step 212: Obtain the outlet water temperature and outlet water flow rate.

[0093] In the embodiment of the present invention, the outlet water temperature may be detected by a water outlet sensor.

[0094] In the embodiment of the present invention, water flows out of the water channel through the water outlet, and the flow meter can detect the water flow rate.

[0095] Furthermore, the outlet water temperature is detected by a flow meter at preset time intervals. The preset time intervals can be set according to system performance and / or implementation requirements during implementation, so that the outlet water temperature can be detected in real time during the heating process. The outlet water temperature is input into the control algorithm (PID algorithm), and the water inflow volume is output, so that the control board can adjust the water inflow of the water dispenser in real time.

[0096] Step 213 , determine whether the outlet water temperature is less than or equal to a preset outlet water temperature threshold or whether the outlet water flow rate is less than or equal to a preset outlet water flow rate threshold. If so, execute step 206 ; if not, execute step 209 .

[0097] In the embodiments of the present invention, the outlet flow rate threshold can be set according to system performance and / or implementation requirements during implementation. This embodiment does not impose any restrictions on the value of the outlet flow rate threshold. The outlet flow rate threshold is the flow rate that ensures that the outlet water temperature does not exceed the set maximum outlet water temperature, provided that no air is mixed into the water path.

[0098] In an embodiment of the present invention, if it is determined that the water outlet temperature is less than or equal to the preset water outlet temperature threshold or the water outlet flow rate is less than or equal to the preset water outlet flow rate threshold, it indicates that the water path is in a water state and heating can be performed, and step 206 is continued; if it is determined that the water outlet temperature is greater than the preset water outlet temperature threshold and the water outlet flow rate is greater than the preset water outlet flow rate threshold, it indicates that the heating tube is in a semi-dry burning state and heating cannot be performed, and step 209 is continued.

[0099] In an embodiment of the present invention, during the heating process of the heating tube, when the water level in the water tank drops to a point where there is almost no water, a small amount of air and water will enter the water path through the water inlet. Due to the small amount of air entering, the water inlet flow rate detected by the flow meter will not drop significantly to the extent that the control board determines that the water path is in a water-short state. However, the water mixed with air will increase the outlet water temperature after entering the heating tube. The control board controls to increase the water inlet flow rate, thereby increasing the water inlet volume to reduce the water temperature. However, increasing the water inlet volume will cause the water in the water path to mix with more air, resulting in a higher outlet water temperature and a greater outlet water flow rate. When it is detected that the outlet water temperature is greater than the preset outlet water temperature threshold and the outlet water flow rate is greater than the preset outlet water flow rate threshold, an alarm is required to stop water discharge and heating to prevent the heating tube from being in a semi-dry burning state and extend the service life of the heating tube. If the outlet water temperature at the outlet is too high, it will cause jetting, posing a safety hazard. Timely alarm and stopping of water discharge and heating can improve safety performance.

[0100] In the technical solution of the heating control method provided by the embodiment of the present invention, before controlling the water dispenser to heat, if it is determined that the water dispenser alarmed when the water supply stopped last time, the water inlet flow rate is detected by a flow meter; if it is determined that the water inlet flow rate is greater than a preset water inlet flow rate threshold, the water dispenser is controlled to heat according to a specified heating power; the water inlet flow rate is detected by a flow meter at a preset time interval; if it is determined that the water inlet flow rate is less than or equal to the preset water inlet flow rate threshold, the water dispenser is controlled to alarm, which can improve the safety performance of the water dispenser.
