The second water supply device is realized in a manner similar to that of the first water supply device, and can be realized by a water pump or a valve.
The working principle of the water dispenser under one scene is described below with reference to fig. 1 and 2, as shown in fig. 3.
When the temperature (specifically, the water temperature) in the first inner tub 11 is less than the first inner tub temperature threshold (T1), the first heating pan 15 starts to be heated.
When the resistance value of the slide resistor 1309 reaches a resistance threshold value (R2, the water consumption amount in the first inner container 11 corresponding to R2 is M1), the second heating plate 23 starts to heat. When the water dispenser is in the first state, the water quantity in the first inner container 11 is M2(M2 is more than M1), the water temperature is T2(T1 is less than T2), and the resistance value of the corresponding slide rheostat 1309 is R1.
After several times of water pumping by the user, the first time of water pumping by the user is water pumping Δ M1, the second time of water pumping by the user is water pumping Δ M2 … …, then the water level in the first inner container 11 is lowered, the first floater 1303 is lowered along with the water level, the second push rod 1306 and the second floater 1304 are raised, and the resistance value of the slide rheostat 1309 is changed accordingly.
In order to avoid frequent heating and boiling of water in the second inner container 21, when the resistance value of the slide rheostat 1309 reaches R2 (namely the water consumption in the first inner container 11 reaches M1), namely when the delta M1+ delta M2 … … + delta Mn is not less than M1, the water dispenser is in the second state, and the second heating plate 23 starts to heat. At this time, the controller 31 sends a water supply instruction to the second water feeder 24 (water pump), and the second water feeder 24 (water pump) starts to supply water from the water source to the second liner 21. When the water level in the second inner container 21 contacts the water sensor 251, the water sensor 251 sends a water immersion signal to the controller 31, the controller 31 sends a water supply stop instruction to the second water supplier 24 (water pump) after receiving the water immersion signal, and the second water supplier 24 (water pump) stops supplying water.
Then, the second heating plate 23 continues to be heated until the temperature detected by the second temperature sensor 26 reaches 100 degrees celsius, and the controller 31 controls the second heating plate 23 to stop heating. Then, the controller 31 sends a water supply instruction to the first water supplier 14 (water pump), and the first water supplier 14 (water pump) starts to supply the water of the second liner 21 to the first liner 11. The second float 1304 then descends until the water in the second inner container 21 is finally pumped out. When the water in the second inner container 21 is completely drained, the resistance value of the slide resistor 1309 is changed from R2 to R1.
This is a cycle of pumping water and heating. If a user continues to pump water by the delta Mn +1 in the circulation process, the second water feeder 24 (water pump) does not pump water, and the water quantity of the delta Mn +1 is recorded in the next circulation process when the current circulation process of heating and pumping water is finished.
