Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, a boiling point determining mechanism for an instant heating type water boiler includes a water outlet pipe 1 made of a non-metal material for discharging boiled water and a capacitance value detecting module 2, two metal conductive plates 3 made of a circular arc shape are arranged on an outer wall of the water outlet pipe 1, an electrode 4 is arranged at one end of each conductive plate 3, the two electrodes 4 are connected with the capacitance value detecting module 2 through a circuit, and the capacitance value detecting module 2 detects a change in capacitance value data between the two electrodes 4 to determine whether water in the water pipe 1 is in a boiling state or a boiled water state, so as to adjust a water outlet temperature state.
Adopt the boiling point of this structure to judge the service environment that the mechanism can make water dispensers self-adaptation different altitudes, need not preset boiling point control parameter, make water dispensers can be suitable for the region of any altitude in national range, avoid continuing the boiling condition at plateau district water, reduce the power consumption that excessive boiling leads to, accomplish quick batch production, save the time of needing readjustment boiling point parameter in response to the region of different altitudes, improve production efficiency, make detecting element need not contact with the water, can save structures such as sealed insulation, and the reduction in production cost, moreover, the steam generator is simple in structure, the control by temperature change is reliable stable.
When the water outlet pipe 1 is in a water-free state, the capacitance value detection module 2 detects that the low-point capacitance value between the two electrodes 4 is an A value, and when the water outlet pipe 1 is in a full water state, the capacitance value detection module 2 detects that the high-point capacitance value between the two electrodes 4 is a B value;

In an actual test, when the water outlet pipe 1 is in a water-free state, only air exists in the water outlet pipe 1, and no metal ions in the water body cause capacitance change, so that the detected capacitance value is the minimum (reference value is 0), and conversely, when the water outlet pipe 1 is in a full water state, the metal ions in the water body enable the detected capacitance value to be the maximum (reference value is 5);
when the water outlet pipe 1 normally discharges water in a boiled water state, the real-time capacitance value is close to a value B (for example, a reference value is 4.5-5), because the water passing through the water outlet pipe 1 is only close to a boiling state and only a small amount of water vapor passes through, the capacitance value detection module 2 can detect that a large amount of metal ions pass through, when the water boiler is used in a high altitude area, the boiling point of the water is reduced, when the water outlet pipe discharges the water, only a large amount of water vapor exists, the real-time capacitance value is at a value A or is close to a value A (for example, the reference value is 0-0.5), the capacitance value detection module 2 judges that the water in the water boiler is excessively boiled, the water boiler can reduce the heating power by controlling the heating device, the water outlet temperature is reduced to a critical boiling state, the generation situation of a large amount of water vapor caused by boiling is reduced, and the mode can enable the water boiler to accurately control the, the situation that boiling generates a large amount of water vapor is not always continuous.
