Description of drawings
Fig. 1 is the structural representation of the utility model in electric kettle.
Fig. 2 is the connection diagram of the utility model heat-generating disc and water level detector.
Fig. 3 is the schematic diagram of the utility model water level detector.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.As Fig. 1, Fig. 2 and shown in Figure 3, the level detecting device of the utility model electric kettle, comprise: the body 1 of electric kettle, heat-generating disc 2, hygrosensor 4, the heat-generating disc 2 of electric kettle is provided with a water level detector 3 that is integrally-built band water-level detecting window 5, and band wiring 6 one ends of described water level detector 3 enter in the cavity under the heat-generating disc 2 by the hole on 2 of the heat-generating discs, and is positioned at the upper surface of heat-generating disc 2.
The housing of water level detector 3 plastic casings of the present utility model is provided with a plurality of detecting windows 5, detecting window 5 is provided with along the axis layering of housing, what expose out in each detecting window 5 is metal conductor portion on the circuit, the common test point that wherein undermost sensing point is a system.Among the CPU or IC circuit on the lead-in wire line attachment plate of the terminal plate 6 of the circuit lower end in water level detector 3 plastic casings.
In the ordinary course of things, drinking water can show the performance of conduction.Because the existing signal that adds in advance of the electronic circuit in the water level detector 3 exists, thereby, when water level is dipped into a certain position, form the loop of a circuit between the water surface and the sensing point.When test contact immerses in the water, the conducting because of the existence of water between sensing point and the common test point, show according to result of the test, when its conducting, its resistance value can reach a few K Ω-hundreds of K Ω, then do not can be considered open circuit between sensing point that water was dipped into and the common test point, promptly resistance value is infinitely great.At this moment, all when detecting resistance and the situation of resistance value between a few K Ω-hundreds of K Ω and occurring, can judge that then the position of each the water-level detecting point under this sensing point is all filled by water.
After immersing in the water, the contact of above-mentioned detector can cause that the resistance value in the water changes, at this moment, can obtain the signal of a voltage and the data of resistance value in the position of each sensing point, the data of these voltage signals and resistance value can be used as the input signal of transistor circuit or IC circuit, amplify identification and carry out calculation process to offer CPU or other IC, processing by operation of data and program, can draw the relevant data parameter of concrete water level, judge peak level and demonstrate the numerical value of concrete water level.
The level detecting device of the utility model electric kettle, simple in structure, the use device is few, cost is low, solve nontransparent surperficial kettle water-level detecting and demonstration problems in use such as metal electric heating kettle and ceramic electric heating kettle, relatively be suitable for the application on electric kettle, coffee pot, ceramic kettle, all steel kettle and other heating electric appliances.Owing to also be provided with hygrosensor 4 in the utility model, in actual use, survey water level and detecting temperature and be used in combination, then will be at electric kettle, coffee pot is in the use of ceramic kettle etc., except that showing the water level function, can also show the temperature of water, will receive better effect.
