Abstract
A timing and temperature exceeding protection device for the gas oven contains a home gas oven, a mechanical timer switch, a temperature control switch, and a motor. The utility model is characterized in that the handle of the mechanical timer switch is installed on the housing close to the gas oven switch. The sensing body of the temperature control switch is installed on the house close to the oven head of the gas oven. On the mechanical switch of the gas oven is installed a driven gear, the driven gear gears with the driving gear driven by the motor. The normal open contact of the mechanical timer switch is connected serially with the normal close contact of the temperature control switch. One of the serially connected ends is connected with one pole of the power supply control circuit. Another end connects with the pole of the relay control coil. Another pole of the relay control coil is connected with another pole of the power supply control circuit. The normal close contact of the relay is connected with the pole of the motor power supply circuit. The control contact of the relay is connected with one end of the motor. Another end of the motor is connected with another pole of the motor power supply circuit.
Description
Technical field
The utility model relates to a kind of timing and overtemperature protection device of gas-cooker.
Background technology
Gas-cooker has manyly also added unnecessary worry to us simultaneously easily bringing for us, such as: vessel have burnt out, food well-done, decoct medicinal herbs is overtime, its reason be exactly gas-cooker not regularly and overtemperature protection device.
Summary of the invention
The purpose of this utility model is timing and the overtemperature protection device that a kind of gas-cooker will be provided, and it can be provided with burning time according to people's needs, and can to guarantee safety, be user-friendly to occurring cutting off source of the gas automatically under the unexpected situation.
The timing of a kind of gas-cooker of the present utility model and overtemperature protection device: comprise household gas range, mechanical timing switch, temperature detect switch (TDS), motor, it is characterized in that: the handle of mechanical timing switch is installed near on the housing of gas stove switch; The temperature sensor of temperature detect switch (TDS) is installed in gas-cooker near on the housing of kitchen range; A driven gear is housed on the hand switch of gas-cooker, and this driven gear is meshed with a driving gear by driven by motor; Normally opened contact in the mechanical timing switch and the normally-closed contact in the temperature detect switch (TDS) are in series, one utmost point of the termination control circuit power supply after the series connection, one end of the control coil of another relay termination, an other utmost point of an other termination control circuit power supply of relay control coil; One utmost point of the normally-closed contact one termination motor power supply of relay, an end of an other termination motor of the control contact of relay, an other end of motor is connected to an other utmost point of motor power supply.
When gas-cooker service time then, time switch disconnects; When the vessel dry combustion method on the gas-cooker, inductor is subjected to hyperthermia radiation, and temperature detect switch (TDS) disconnects.And the disconnection of these switches just, under the effect of relay, machine operation drives the gas stove switch action, closes source of the gas, and motor stops operating then.
Advantage of the present utility model is: the one, can prevent from effectively to cause that contingency such as fire takes place owing to the gas-cooker temperature is too high, and guarantee people's living safety.The 2nd, this utility model can be provided with burning time according to people's needs, makes things convenient for the user.The 3rd, this utility model principle is reasonable, and simple structure is easy to use, has bigger promotional value.

The specific embodiment
Further specify operation principle of the present utility model below in conjunction with embodiment and accompanying drawing.
The timing of gas-cooker and overtemperature protection device: comprise household gas range, mechanical timing switch, temperature detect switch (TDS), motor, it is characterized in that: the handle of mechanical timing switch is installed near on the housing of gas stove switch; The temperature sensor of temperature detect switch (TDS) is installed in gas-cooker near on the housing of kitchen range; A driven gear is housed on the hand switch of gas-cooker, and this driven gear is meshed with a driving gear by driven by motor; Normally opened contact in the mechanical timing switch and the normally-closed contact in the temperature detect switch (TDS) are in series, one utmost point of the termination control circuit power supply after the series connection, one end of the control coil of another relay termination, an other utmost point of an other termination control circuit power supply of relay control coil; One utmost point of the normally-closed contact one termination motor power supply of relay, an end of an other termination motor of the control contact of relay, an other end of motor is connected to an other utmost point of motor power supply.Described control circuit power supply is dc source or AC power.Described motor is alternating current generator or direct current generator; Described motor power supply is AC power or dc source.
As shown in the figure, S1 is the normally opened contact of mechanical timing switch;
The normally-closed contact of S2 temperature detect switch (TDS);
K1 is relay and contact;
MOTER AC is a motor.
The control circuit power supply is a dc source ,+9V;
Motor is an alternating current generator, and power supply is an AC power ,～220V.
When gas-cooker service time then, time switch disconnects, by relay, motor circuit closure, the gear on the gear driven gas stove switch on the motor, source of the gas is closed, motor stops; A little while, time switch is closed again, and wait restarts.
When the vessel dry combustion method on the gas-cooker, inductor is subjected to hyperthermia radiation, and temperature detect switch (TDS) disconnects, by relay, and motor circuit closure, the gear on the gear driven gas stove switch on the motor, source of the gas is closed, and motor stops; Treat that temperature descends, temperature detect switch (TDS) is closed again, and wait restarts.
Embodiment: time switch, temperature detect switch (TDS), relay, motor are installed on the gas-cooker in strict accordance with conspectus, and on motor and gas stove switch, install meshing gear mutually; The circuit of gas-cooker is parallel in the smoke exhaust ventilator; Range surface temperature was consistent when the temperature of temperature detect switch (TDS) should be transferred to the vessel dry combustion method.
