The present invention relates to an automatic opening and closing and alarm device for the heating device of the cooking stove.

In recent years, accidents such as poisoning caused by domestic gas (particularly liquefied propane gas), fire, explosion, and casualties caused by them tend to increase. One of the causes of these accidents is that the water overflowed from the cooker during the use of the gas comes into contact with the flame during combustion and the fire is turned off, causing the gas to leak.

The present invention is to provide a device to prevent the accident of gas caused by such a cause and to save energy, to prevent the leakage of unburned gas generated at the same time as the flame is turned off and to provide an alarm device. .

As unburned gas continuously leaks and accumulates in a certain space and accumulates, a sudden spark may cause a fire and an explosion, or may cause a user to choke.

The present invention is to develop a safe automatic opening and closing device to save energy and prevent accidents in consideration of the dangerous phenomenon as described above.

The present invention is characterized by constructing a burner plate in which overflowed water flows to an inclined U-shaped demand, and the overflowed water flows through the outlet and then is connected to a water switch. Water dvop detector). In addition, a solenoid valve is provided in the gas delivery pipe and connected to the drop detector switch.

The solenoid valve is operated to close the supply of gas fuel when the droplet detector switch is closed.

In addition, the control circuit is composed of a voltage drop transformer, a full-wave rectifier, a capacitor for stabilizing a current wave, and a drop detector switch. The relay is actuated by this switch and connects the alarm and solenoid valve in parallel so that the alarm triggers an alarm and the solenoid valve is closed.

Therefore, an object of the present invention is to save the loss of gas and to prevent the occurrence of dangerous.

If electrical energy actuates the burner plate or heating element, the burner plate shall take the form of an insulating plate with heating coils.

The insulation plate is deformed to form a U-shaped request inclined so that the water overflowed on the burner plate drains, and the water falls to the water droplet detector which operates the control circuit.

Hereinafter, the present invention according to the accompanying drawings as follows.

A burner plate 2 composed of U-shaped requests inclined in FIGS. 1 and 2 is provided in a burner apparatus such as the cooking stove 1.

This U-shaped request is led to a drain port (3), and the drop detector (4) is provided below the discharge port (3).

Two clamps 5 are firmly held by the drop detector 4.

The drop detector 4 is located below the drop container 6 so as to be in contact with the sump of drainage water.

The water container 6 can be inserted and removed such as mounting of a table.

As in FIG. 3, the electrical members excluding the clamp 5, i.e. the transformer 7, the condenser 8, the relay 9 and the alarm 10, are assembled in a box 11 of heat-resistant material and burner Is protected from heat.

The solenoid valve 14 is provided in the gas delivery pipe 13 drawn out from the gas cylinder 12, and consists of the gas inlet 14a, the gas outlet 14b, and the power supply wire 14c.

This solenoid valve 14 is regulated by a relay 9, the gas inlet 14a is connected to the gas cylinder 12, and this valve 14 is closed when acting by a control circuit.

When the drainage passes through the inclined U-shaped request on the burner plate 2, the drainage flows through the drain outlet 3 to the water droplet detector 4 to operate the control circuit, and the alarm 10 and the solenoid valve 14 To activate the relay.

In this design, the home standard voltage of 110V is dropped to 12V through a transformer.

The secondary current is rectified by a bridge full-wave rectifier 15.

The rectified secondary current is smoothed or stabilized by the condenser 8.

In this design, the capacitor is defined as 500μf and 25V.

When drainage flows into the drop detector 4 and connects the drop detector terminal, current flows through the relay 9 to operate the relay 9.

When the relay 9 is operated by the closed circuit of the connection terminal of the drop detector 4, the contact is connected so that the alarm 10 and the solenoid valve 14 are connected to a line voltage.

5 shows that the alarm 10 and the solenoid valve 14 are connected in series, such as a relay contact.

The circuit of Figure 5 shows a relay that can act as a 12V D.C.

Another example of a part of the electrical circuit is shown in FIG.

In this embodiment, the transformer and rectifier can be replaced by transistors, drop resistors and filter networks to provide the operation of the relay.

In the case of using electricity rather than gas generating cooking heat, an example of the present invention includes an insulating plate 16 and a gas heat coil 17 as shown in FIGS. 8 and 9.

The heating coil 17 is disposed in the U-shaped request of the insulating plate. In addition, the drip hole 18 is drilled at a specific position so that the discharged drop can be collected, and this drop flows through the burner plate so that it accumulates and flows to the drop detector connected to the control circuit.

In FIG. 7, control relay RL ₁ operates to actuate alarm A and line relay RL ₂ to open the burner or heater connected to this relay contact.

As described above, the present invention can be used as a general gas stove under normal conditions when supplying a predetermined gas and power, and if the boiled solution overflows from the container of food during use, the overflowed solution is in accordance with the inclined U-shaped requirements of the burner plate. It is collected in the water container through the drain outlet and the water drop detector.

The solution detects water droplets by connecting a terminal to the relay and current to the solenoid valve and alarm, and closes the gas pipe and alarms.

Therefore, the user can ensure safety by tightening the valve of the gas cylinder, and the water container can be taken out from the front of the gas stove to remove the excess water, and the wet water detector can be washed well and prepared for the next use.

In this way, the present invention can prevent the disaster caused by the leakage of the gas when extinguishing by the solution overflowed in the container in the stove.
