Abstract
The invention discloses an electric kettle control circuit. A steam automatic power off switch is adopted, so that after water in an electric kettle is boiled, steam can be generated, a metal plate in the steam switch is heated to be deformed, the switch is automatically ejected, and a circuit is powered off; a temperature controller is adopted to play a role in dry burning-resistant protection in the electric kettle; a thermal fuse is adopted, so that when the switch is out of function, the thermal fuse can be fused along with the raising of temperature, and the electric kettle is powered off; an indicator light (neon tube) HL is designed to be connected with a current limiting resistor R in series and connected with a water boiling heater in parallel, so that when the electric kettle circuit is switched on to form a water boiling state, the water boiling heater is in voltage power supply, the HL can be luminous to indicate a water boiling heating state. When the water temperature is higher than 96 DEG C, and after the steam automatic power off switch is powered off, the electric kettle circuit is at a disconnected state, and the indicator light HL is turned off. The electric kettle control circuit provided by the invention is high in safety, low in design cost, and favorable in market application prospect.

Summary of the invention
The present invention solves above-mentioned technical problem, it is proposed that a kind of control circuit for electric kettle, by design steam type from dynamic circuit breaker
Electric switch, temperature controller and thermal cut-off, realize the security control of insulating pot.
The technical solution used in the present invention is: a kind of control circuit for electric kettle, including: steam type switchs automatically, temperature controller,
Thermal cut-off, heater；Described steam type automatically switchs one end and is connected with live wire, and steam type switchs the other end and temperature control automatically
Device the first end connects, and described temperature controller the second end is connected with thermal cut-off the first end, described thermal cut-off the second end and heater
First end connects, and described heater the second end is connected with zero line.
Further, also include that display lamp, described display lamp the first end are connected with temperature controller the first end, described display lamp second
End is connected with heater the second end.
Further, also include that current-limiting resistor, described current-limiting resistor are connected with display lamp, the first end of current-limiting resistor
Being connected with display lamp the second end, the second end of current-limiting resistor is connected with zero line.
Beneficial effects of the present invention: a kind of control circuit for electric kettle of the present invention, by using steam type automatic power-off switch,
After the water in electric kettle is boiled, steam can be produced, make the sheet metal temperature distortion in steam cock, switch of automatically upspringing,
Disconnecting circuit；Use temperature controller, serve in electric kettle and prevent dryouting protective effect, as put on the heaters when kettle is long,
Can repeatedly heat, the water in kettle can constantly reduce, the double gold when water level is too low or dry-fire condition occurs, in temperature controller
Belong to sector-meeting work, make circuit disconnect；Use thermal cut-off, when aforesaid switch is the most ineffective when, along with temperature
Raising (about 139 DEG C), thermal cut-off can be blown, and makes electric kettle power-off；And the application designs display lamp (neon tube)
HL and current-limiting resistor R series connection, is in parallel connection with heater to boil water, when electric kettle circuit is in path, shape to boil water
State, when heater to boil water has voltage power supply, HL can be luminous, indicates heated condition to boil water.When water temperature is higher than 96 DEG C, steam
After formula automatic power-off switch disconnects, electric kettle circuit is in off state, and display lamp HL extinguishes, and the peace of the present invention
Quan Xinggao, design cost is low, and market application foreground is good.
