Detailed Description
The invention is further illustrated with reference to the following figures 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 2 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;
when the heated water body is discharged through the water outlet pipe 1, the real-time capacitance value is at the B value or close to the B value, the water body is judged to be in a boiling water state, the water outlet temperature of the water boiler is controlled to be stable, when the heated water body is discharged through the water outlet pipe 1, the real-time capacitance value is at the A value or close to the A value, the water body is judged to be in a boiling state, the water outlet temperature of the water boiler is controlled to be reduced, and the water outlet temperature is in a critical boiling state.
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 the 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 discharging 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.
The heating power is reduced only by one embodiment, and as a replacement means, under the condition that the heating power is kept unchanged, the capacitance value detection module 2 can be used for controlling a water pump in the water boiling machine to increase the water outlet quantity of the water outlet pipe 1, when the water quantity is increased, the heat generated when the water body is boiled is dispersed, the water outlet temperature is reduced, and the water body can be stabilized in a boiled water state (namely the water body is not boiled or in a critical boiling state).
When the water boiler works in a negative altitude area, the boiling point of the water body is increased, and the heating device works at full power when used under the condition of standard atmospheric pressure, so that when the water boiler works in the negative altitude area, the water pump of the water boiler can be controlled only through the capacitance value detection module 2, the working power of the water pump is reduced, the retention time of the water body in the heating device is prolonged, and the heating time of the water body is prolonged to boiling.
The low-point capacitance value A and the high-point capacitance value B belong to domain values, and because the parameters of the capacitance values are set before leaving the factory, the parameters are influenced by other factors such as the material of the water outlet pipe 1, the thickness of the pipe wall, the inner diameter of the water outlet pipe 1 and the like, the domain values of the values are obtained through factory limit tests on the real-time capacitance values of the A value, the B value and the boiling point.
An annular groove 101 matched with the width of the current-conducting plate 3 is concavely arranged on the outer end face of the water outlet pipe 1, the current-conducting plate 3 is tightly installed in the annular groove 101 (shown in figure 3), and the outer surface of the current-conducting plate 3 is flush with the outer end face of the water outlet pipe 1; this structure installation is fixed convenient and fast, can improve assembly efficiency, shortens the distance between current conducting plate 3 and the water, and after the assembly, can make the outlet pipe wholly maintain level and smooth.
An annular groove 101 is formed in the outer end face of the water outlet pipe 1, and the conductive plate 3 is sleeved in the annular groove 101 and integrally encapsulated in the pipe wall of the water outlet pipe 1 through injection molding (see fig. 4); can prevent that wearing and tearing from appearing in current conducting plate 3 and the outer terminal surface of current conducting plate 3 oxidation appears, make the data that detect more stable accurate, reduce the influence that the air bed between current conducting plate 3 and the outlet pipe 1 caused.
The injection-molded fixing can also be used to inject limiting parts 102 (shown in fig. 5) for limiting the conductive plate 3 at two ends of the annular groove 201, and the limiting parts 102 are pressed against two side edges of the conductive plate 3.
As shown in fig. 2, a detection chip mounting box 5 is arranged on the water outlet pipe 1, a detection chip 6 is mounted in the detection chip mounting box 5, the capacitance detection module 2 is arranged in the detection chip 6, and two end portions of the conductive plate 3 extend into the detection chip mounting box 5 and are connected with the detection chip 6; this structure can reduce the boiling point and judge the volume of mechanism, shortens the transmission distance of circuit to data, better protection detects chip 6.
