Abstract
The utility model relates to a time delay control device of an electric kettle, which comprises a regulated power supply, a bidirectional thyristor KS connected with an electric hot tray RL in series, a microprocessor MCU, a switch triode VT, a voltage division circuit formed by a temperature sensor RT1, a capacitor C1 and a resistor R1, and a water boiling monitoring circuit formed by the voltage division circuit and an I/O port PA3 of a micro-controller. When the micro-controller detects that the water temperature reaches 100 DEG C, the micro-controller conducts internal operation and comparison, controls the bidirectional thyristor KS to be cut off after time delay for 2 to 3 minutes, and stops heating. As the technical proposal is adopted, the electric kettle can delay for 2 to 3 minutes after the water is boiled, thus leading the water in the kettle to conform to the drinking water standard and protecting the health of people.
Description
Technical field
The utility model relates to the control device of insulating pot.
Background technology
It is bigger to contain concentration of narmful substance such as bleaching powder in the running water, and after the running water boiling, content of harmful can descend rapidly, facts have proved, and be good in about 2-3 minute generally in running water boiling back.But, existing electric kettle (device), especially powerful insulating pot, general power is all at 1500-1800KW, the speed that boils water is very quick, temperature control equipment in the insulating pot generally adopts bimetallic single-throw type switch, and water-in-kettle is heated to boiling temperature, and bimetal leaf will be out of shape, when acquiring a certain degree with regard to deenergization, therefore, ask too shortly when the boiling of existing insulating pot continues, do not meet the drinking water national standard.
Summary of the invention
The utility model is exactly the overrun control of a kind of insulating pot that proposes in order to overcome the shortcoming that prior art exists, and makes that water time-delay boiling continues 2-3 minute in the insulating pot, to meet the drinking water national standard.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of insulating pot overrun control comprises power switch and the electric hot tray RL that is arranged on the insulating pot bottom, it is characterized in that also comprising: a voltage-stabilized power supply; A bidirectional thyristor KS who connects with electric hot tray RL; A microprocessor MCU, it can adopt single-chip microcomputer, or PLC; A switch triode VT, its base stage links to each other with microprocessor MCU, and colelctor electrode extremely links to each other with the control of bidirectional thyristor KS; A temperature sensor RT1 who links to each other with microprocessor MCU;
According to above-mentioned basic technical scheme, with further technical scheme be: be provided with one and control circuit by precision resistance RT2 and by the anti-dry that the resitstance voltage divider that capacitor C 2, resistance R 2 constitute is formed, MCU links to each other with microcontroller.
Since adopted technique scheme, by microcontroller as required,, control heater makes water boiling back time-delay 2-3 minute, and outage makes water-in-kettle can meet drinking water standard then.Also has the major accident that can prevent dry combustion method in addition.
Description of drawings:
Fig. 1 is the schematic diagram of the overrun control that provides of the utility model.
The specific embodiment
A kind of insulating pot overrun control comprises power switch and the electric hot tray RL that is arranged on the insulating pot bottom, it is characterized in that also comprising: a voltage-stabilized power supply, output 5V and 12V; A bidirectional thyristor KS who connects with electric hot tray RL; A microprocessor MCU; A switch triode VT, its base stage links to each other with the I/O mouth PA1 of microprocessor MCU, and colelctor electrode extremely links to each other with the control of bidirectional thyristor KS; The bleeder circuit that temperature sensor RT1 and capacitor C 1, resistance R 1 constitute, the water that it and micro controller I/O mouth PA3 the form observation circuit that seethes with excitement.When water temperature was lower than 100 ℃, microcontroller PA1 was a low level, not conducting of switch triode VT, and bidirectional thyristor KS controls very high level and conducting, the electric hot tray RL heating of working.When microcontroller when temperature sensor RT1 detects water temperature when reaching 100 ℃, microcontroller through internal arithmetic relatively, delay time after 2-3 minute, microcontroller PA1 is a high level, switch triode VT conducting, bidirectional thyristor KS controls very not conducting of low level, and bidirectional thyristor KS outage stops heating.
An anti-dry control circuit of forming by precision resistance RT2 and by the resitstance voltage divider that capacitor C 2, resistance R 2 constitute is set in addition, and the I/O mouth PA1 of it and microcontroller MCU links to each other.When microcontroller when temperature sensor RT1 detects water temperature when reaching 105 ℃; microcontroller through internal arithmetic relatively; microcontroller PA1 is a high level; switch triode VT conducting; bidirectional thyristor KS controls very not conducting of low level; bidirectional thyristor KS outage is not damaged with the protection insulating pot.
