Abstract
The utility model relates to an electric kettle, in particular to an electric kettle utilizing vibrating induction to measure water temperature changes and water boiling, which is provided with a vibrating sensor, wherein the vibrating sensor is attached onto an electric kettle base and is connected to an electric kettle control panel via a lead wire. The electric kettle can rapidly and reliably determine whether water is boiling or not by utilizing the method which can not be affected by surrounding environmental temperature, and has the advantages of accurate measurement, fast response and the like.
Description
Technical field
The utility model relates to a kind of electric kettle, especially a kind of electric kettle that utilizes vibrating sensing to measure the boiling of water temperature variation and water.
Background technology
The main temperature measuring equipment of electric kettle is to utilize the far infrared thermometry to measure temperature of boiler at present, and the electric kettle of design specialized is touched tool, makes the infrared thermometry sensor directly facing to the pot body, but the cost costliness.In addition, because the boiling point difference of different altitude height water, these two kinds of methods in fact still can not promptly and accurately be measured the boiling of water outlet.And the boiling of water except may not having boiled just shutdown in advance, also may produce and boil as can not promptly and accurately measuring, and problem such as overflowed.
Therefore, how timely, accurately measure temperature of boiler particularly the boiling of water be the important technological problems that perplexs the electric kettle industry at present.
Summary of the invention
The purpose of this utility model is to provide a kind of measurement accurate, reflects electric kettle fast.
In order to reach above-mentioned creation purpose, a kind of electric kettle of the utility model is provided with a vibrating sensor, and this vibrating sensor is attached under the panel of electric kettle base, and is connected to the electric kettle control panel by lead-in wire.
This electric kettle control panel is provided with amplifying circuit and single-chip microcomputer, and described piezoelectricity switching signal is amplified by amplifying circuit, carries out analysis and judgement by single-chip microcomputer again.
This electric kettle also comprises thermistor or far infrared temperature measuring equipment.
This vibrating sensor is a piezoceramic transducer.
Compared with prior art, the utility model electric kettle utilizes vibrating sensor to measure the boiling of water temperature variation and water, thereby can judge reliably quick and precisely whether water seethes with excitement, and this mode is not subjected to the influence of ambient temperature.
Description of drawings
Fig. 1 is the schematic diagram of the utility model electric kettle;
Fig. 2 is the schematic diagram that Fig. 1 the utility model electric kettle temperature measuring equipment constitutes.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model electric kettle is described further.
As shown in Figure 1, the panel of the base 2 of electric kettle body 13 times, near the position of base panel 3, adhere to a vibrating sensor 4 (as piezoelectric ceramics), this vibrating sensor 45 is connected to electric kettle control panel 6 by going between.As shown in Figure 2, during thermometric, piezoelectric vibration sensors (piezoelectric ceramics) is connected to the piezoelectric vibration signal on the electric kettle control panel by lead-in wire, is amplified by the amplifying circuit on the electric kettle control panel, MCU (single-chip microcomputer for example closes safe HT46R47 series monolithic) analysis and judgement.
The control mainboard can amplify shaping to the piezoelectric vibration signal, and carries out LPF, to reduce the influence of ambient sound and higher hamonic wave.Because piezoelectric transducer directly is attached to panel, its heat up water vibration duration that causes and amplitude are much higher than ambient sound to be disturbed, the easiest realization of therefore anti-sound interference.

Obviously, two characteristics are arranged when water boils, one: frequency sharply descends, and will boil in several seconds that water boils from water, and frequency has the sudden change that descends; Its two: frequency is lower, and amplitude was bigger when water boiled greatly.Can infer the boiling of water in view of the above easily.It is low to high that whole heating process then has frequency to have, and general trend from high to low meets with daily life general knowledge again.Through the test of actual (tube) length time, judge that water boils the time promptly and accurately, and be not subjected to temperature, the influence of situations such as circulation of air.
After water drove keeping warm mode into less, if add water, water temperature changed, and can cause that frequency of oscillation changes, and entered heated condition automatically thereby can control electric kettle, and this function is in that to boil the tea time particularly useful.
Piezoelectric vibration sensing temperature measuring equipment can independently use, and also can comprehensively use in conjunction with diffusing resistance of heat or far infrared temperature measuring equipment, with the heating process of finer control electric kettle.
