Abstract
The invention relates to an automatic control electric kettle, which comprises an alternating current power supply (1), a slide rheostat (2), a thermistor (3), a heating resistance wire (4), an electromagnetic relay (5) and leads (6); in a control circuit, the thermistor (3), the alternating current power supply (1) and the slide rheostat (2) are in series connection by the leads (6), and the leads (6) are wound around an iron rod of the electromagnetic relay (5). An external circuit and the control circuit are in parallel connection. In the external circuit, the alternating current power supply (1), the electromagnetic relay (5) and the heating resistance wire (4) are in series connection. When water in the electric kettle boils, the automatic control electric kettle can automatically power off, and after the temperature of the water is reduced, the automatic control electric kettle can automatically heat the water; the automatic control electric kettle improves the safety coefficient and avoids damage.
Description
Technical field:
Designing technique of the present invention designs a kind of insulating pot of automatic switch.
Background technology:
At present, insulating pot great majority on the market only have warning device.But busyly after people's plug-in be sometimes away from home, after water boiling, warning device will sound always.Not only can produce noise, and can not auto-breaking, insulating pot is destroyed.Therefore a kind of Autocontrolled electric kettle is very useful.
Invention designing technique content:
Designing technique of the present invention problem to be solved be to design a kind of can the insulating pot of auto-breaking after water boiling.For solving above technical problem, design technology project of the present invention is as follows:
A kind of Autocontrolled electric kettle comprises AC power (1), slide rheostat (2), thermistor (3), heating resistance wire (4) electromagnetic relay (5), wire (6).
In control circuit, thermistor (3), AC power (1) are connected with slide rheostat (2) wire (6), and wire (6) is around on the iron staff in electromagnetic relay (5).External circuit is in parallel with control circuit.In external circuit, AC power (1), electromagnetic relay (5) are connected with heating resistance wire (4).
The beneficial effect of designing technique of the present invention is:
When the water in insulating pot seethes with excitement, designing technique energy auto-breaking of the present invention, until after coolant-temperature gage decline, again can Automatic-heating.Safety coefficient can be increased and prevent electric water to be destroyed.
Accompanying drawing illustrates:
Fig. 1 is the overall schematic that designing technique of the present invention is implemented.
Detailed description of the invention:
Further illustrate below in conjunction with drawings and Examples invention designing technique.
As shown in the figure: designing technique of the present invention primarily of AC power (1), slide rheostat (2), thermistor (3), heating resistance wire (4) electromagnetic relay (5), wire (6).
In control circuit, thermistor (3), AC power (1) are connected with slide rheostat (2) wire (6), and wire (6) is around on the iron staff in electromagnetic relay (5).External circuit is in parallel with control circuit.In external circuit, AC power (1), electromagnetic relay (5) are connected with heating resistance wire (4).
The present invention uses like this;
Slide rheostat (2) protecting control circuit.The resistance that temperature along with water raises thermistor (3) reduces, and the electric current in control circuit increases, and makes electromagnetic relay (5) cut-off switch, stops heating.When temperature declines, thermistor (3) resistance increases, and control circuit electric current reduces, and switch restores, and reheats.Thus reach the effect of auto-breaking protection insulating pot.
Claims (3)
1. an Autocontrolled electric kettle comprises AC power (1), slide rheostat (2), thermistor (3), heating resistance wire (4) electromagnetic relay (5), and wire (6) is formed.
2. slide rheostat (2) protecting control circuit.The resistance that temperature along with water raises thermistor (3) reduces, and the electric current in control circuit increases, and makes electromagnetic relay (5) cut-off switch, stops heating.When temperature declines, thermistor (3) resistance increases, and control circuit electric current reduces, and switch restores, and reheats.Thus reach the effect of auto-breaking protection insulating pot.
3. in control circuit, thermistor (3), AC power (1) are connected with slide rheostat (2) wire (6), and wire (6) is around on the iron staff in electromagnetic relay (5).External circuit is in parallel with control circuit.In external circuit, AC power (1), electromagnetic relay (5) are connected with heating resistance wire (4).
