Abstract
The utility model discloses an electric kettle which is provided with a kettle body and a base separated from the kettle body. A heating control circuit is arranged in the base, and is provided with a heating switch and a heating body located in the kettle body, and a delay control circuit located in the base; the delay control circuit is provided with a current transformer, a signal amplifying circuit and a delay control module; the current transformer senses the current of a heating-body line; the signal output end of the current transformer is connected with the signal amplifying circuit; the output end of the signal amplifying circuit is connected with the delay control circuit; the output end of the delay control circuit is connected with a triode, and a collecting electrode end of the triode is connected with a relay; a normally-open switch of the relay is connected with the diode in serial and then is connected with the heating switch in parallel.
Description
Technical field
The utility model belongs to technical field of living goods, particularly a kind of electric kettle.
Background technology
Along with the raising of people's living standard, electric kettle has become family life small household appliances commonly used.Electric kettle major part on the market all is after adding entry now, press the heating power supply switch, electric heating plate is started working, water burns and to produce a large amount of steams when seething with excitement, and steam blows to the bimetal leaf of electrical heating kettle by a gas port, and bimetal leaf is subjected to the influence of steam temperature, produce deformed movement, touch the heating power supply switch, make the electric kettle outage, stop to continue heating.The method that boils water of science is to burn to boiling at water, continues little fire heating again boiling was kept 3-5 minute, can kill bacterium, removes the material of harmful human body.The structure of existing electric kettle can not reach above-mentioned requirements.
The utility model content
For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of new electrically heating kettle that can continue to keep the boiling certain hour after water is boiled.
For achieving the above object, the technical solution adopted in the utility model is: this new electrically heating kettle has kettle body and the base that separates with the kettle body, be provided with heating control circuit in the described base, it is characterized in that: described heating control circuit has the heater switch that is positioned at the kettle body, calandria and the delay control circuit that is positioned at base, described delay control circuit has current transformer, signal amplification circuit and time-delay control module, the electric current of described current transformer induction heater circuit, the signal output part of current transformer connects signal amplification circuit, the output of signal amplification circuit connects delay control circuit, the output of delay control circuit is connected with triode, the collector terminal of triode connects relay, and is in parallel with heater switch behind the normal open switch series diode of relay.
Adopt the beneficial effect of technique scheme: this new electrically heating kettle has current transformer, and current transformer detects the hot-water bottle heated condition, if there is not electric current, shows not heating, has electric current then to show at heated condition.Testing circuit judge electric kettle by heated condition after stop heated condition, output signal is amplified through amplifying circuit, thereby trigger delay control circuit work, be the actuating of relay, the normal open switch closure of relay, through the diode current limliting heater is powered, the heating of heater small-power makes boiling water keep fluidized state.When timing finishes, relay electric-loss, the normal open switch of relay disconnects heater circuit, thereby stops heating.3-5 minute lasting heating can be set as required, can kill bacterium, remove the material of harmful human body, make drink water more science, health.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is circuit theory diagrams of the present utility model.
The specific embodiment
Electric kettle as shown in Figure 1, have kettle body and the base that separates with the kettle body, be provided with heating control circuit in the described base, described heating control circuit has the heater switch K that is positioned at the kettle body, calandria R and the delay control circuit that is positioned at base, described delay control circuit has current transformer CT, signal amplification circuit and time-delay control module, signal amplification circuit is made of the LM324 integrated package, the electric current of current transformer CT induction heater R circuit, the signal output part of current transformer CT connects signal amplification circuit, the output of signal amplification circuit connects delay control circuit, delay control circuit is made of 555 circuit, the output of delay control circuit is connected with triode T2, the collector terminal of triode T2 connects relay coil J3, and is in parallel with heater switch K behind the normal open switch J3-1 series diode D of relay.The delay time of time-delay control module N can be set as required, generally is controlled at 3-5 minute, is no more than 10 minutes at most, can kill bacteriums whole in the water basically, and remove the material of harmful human body, makes the more science health of drinking water.
