Embodiment
Below in conjunction with concrete embodiment, the present invention will be described.
As shown in Figure 1, a kind of method for controlling water level that is applied to drinking equipment, includes following steps, is specially:
A, pole plate is positioned in the water tank of drinking equipment and direct supply is connected to pole plate, when water tank is in the time that full water state and pole plate are flooded completely by the potable water in water tank, the medium in the middle of pole plate is potable water; When water tank is during in anhydrous state, the medium in the middle of pole plate is air; In the time that water tank is between full water state and anhydrous state, the medium in the middle of pole plate is air and potable water;
B, by the capacitance signal of capacitive transducer real-time detection pole plate;

Need further to explain, in the time that water tank is between full water state and anhydrous state, air and potable water are as the medium in the middle of pole plate, because the specific inductive capacity of air and the specific inductive capacity of potable water are at a distance of very large, thereby make pole plate there is high susceptibility to potable water, also just there is high stability and reliability; Along with the capacitance variations of pole plate, its essence is that potable water is as medium, in the variation of the polar plate area of potable water medium, the capacitance variations of bringing by the medium area change corresponding with pole plate is judged water level value.For drinking equipment, particularly intelligent drinking equipment, obtaining of direct supply is to be relatively easy to, so also just the decline of relatively traditional drinking equipment is a lot of for its cost.
In addition, wireless network communication module is WIFI wireless network communication module.
