This design makes gas lanes ignite and burn with a simple touch and automatically stops combustion by setting food heating time appropriately so that housewives can freely enjoy leisure activities or other necessary actions during cooking time. It relates to a cooking device.

Conventionally, when cooking various foods, the gas is automatically shut off by the timer to complete cooking of the food heated by the heat source of the gas, but this is usually done by connecting the gas passage by directly connecting the timer to the gas cylinder. It is a structure that locks the valve after the set timer has elapsed, and springs and gears are interconnected and operated so that the weak housewives need a lot of effort and force to artificially reposition or operate the method. Not only was there a lot of difficulty in deciding or fixing the setting time at the same time as the value of the commodity, but there were problems that housewives felt anxiety due to the lack of reliability as a result of various safety accidents caused by gas.

The present invention is designed to solve the conventional problems and at the same time all the operations to improve the value of the goods by electronic methods and to prevent various safety accidents as described in detail by the accompanying drawings as follows.

For example, the gas stalks 3 are connected to the burner head 2 on both the left and right sides of the main body 1 provided with two combustion books.

Gas-coke (3) has a through-hole (5a) (5b) (5c) is intermittent to the contact plate 6 of the solenoid (S1) (S2) (S3) so that the interconnection to the injection hole (4) is a gas When the gas supplied from the inlet pipe 7 is supplied to the burner head 2, it is opened and closed when an electrical signal is connected to each solenoid S1, S2, S3, and when the three contact plates 6 are reversed. Gas is supplied in three stages, and as shown in FIG. 3, electricity is connected to only one solenoid S1, and when the through hole 5a is opened, the gas is burned in the burner head 2 in one stage. In addition, when the two contact plates 6 are reversed, the food is burned as two stages of intermediate thermal power, and these solenoids may be made of two or four through holes depending on the required use in the same number.

The time display of the timer 8 is exposed on the front of the main body 1 of the gas lanes, and the timer adjustment switch SW1, the clock focus switch SW2, the hour set switch SW3, and the minute set are set. Switch (SW4), timer start switch (SW5), valve off switch (SW6) (SW7), valve control switch (SW8) (SW9), high pressure switch (SW10), etc. The ignition plug 9 and the heat sensor 10 are fixed to the burner head 2 located at both sides.

In the present invention, when the clock adjustment switch (SW2) is pressed in order to adjust the current time, the hour display part and the minute display part blink, and at this time, the user adjusts the set switch (SW3) and then the minute set switch (SW4). ) To work on displaying the current time and time.

When the timer control switch SW1 is pressed, the hour and minute indicators flash again, and the state where it is possible to adjust the gas combustion time, that is, the cooking completion time, is set in the set switch SW3 and the minute set switch SW4. Press the high pressure switch (SW10) to finish the setting operation by pressing the high pressure electricity from the high-pressure generator (11) to generate a spark from the ignition plug (9), in this case is installed on one side of the gas scope (3) And each of the solenoids S1, S2, and S3, which intercepts the through holes 5a, 5b, and 5c, is opened to start combustion after ignition by sparking as the gas is supplied to the burner head 2. Since the cooking vessel is heated, the user presses the timer start switch (SW5) to operate the set reservation time.

The high pressure generator 1 makes the applied constant voltage to discharge high voltage necessary for ignition and stops after generating the spark for only 3 seconds by the role of the timer 8 connected to the MPU 12 and confirms whether it is in an ignition state. The heat detection sensor 10 fixed to one side of the burner head 2 detects an electromotive force by the heat being burned, and thus the signal is transmitted to the MPU 12 through the comparator 13 so that the combustion state can be known. The flashing of the light emitting diodes (LEDs) exposed on the front of the main body 1 allows the user to grasp from the outside.

The MPU 12 has a function of a single chip microproccesor unit, and serves to automatically process all kinds of functions, and is installed on the left and right burner heads 2 and the heat sensor 10 And an input signal according to the operation of various switches to output an electrical signal to control the operation of the solenoids S1, S2, and S3 formed on the timer 8 and the gas cock 3 in more detail. The explanation is as follows.

First, as described above, the setting switch SW3 and the minute set switch SW4 are pressed the proper number of times in order to set the timer 8 and the present time. When the setting operation is finished, the digital display unit exposed on the front of the main body 1 is displayed. The signal output from the MPU 12 is displayed in the segment via the inverter 14 and the decoder 15, the current time is displayed and the set time of the timer, that is, cooking completion time, is stored. When the signal is pressed, the signal is inputted to the MPU 12 and then amplified by the amplifier 17 through the latch circuit 16, and then the IC relays I.R1, I.R2, and I.R3 are contacted. Accordingly, each solenoid S1, S2, S3 is opened to supply the gas necessary for ignition. In this case, one of the two burner heads 2 is selected between the left and right sides of the main body 1. Press the valve OFF switch (SW6) (SW7) to operate only the gas shaft 3 on one axis or ignite both sides. When it is turned on, or both sides are selected to ignite, the spark generated from the high-pressure generator for 3 seconds and the solenoids S1, S2, and S3 of the selected direction are pulled by the electrical signal and burned after ignition with the highest fire power. will be.

When the user wants to operate the thermal power according to the user's required selection, the solenoid S1 (S2) opened by pressing the one of the left and right valve control switches SW8 and SW9 exposed on the front of the main body 1 once again is pressed. One of the solenoids (S1) on one side of the (S3) is cut off the electrical signal, and the gas passage hole (5a) is blocked, and if pressed once again, the solenoid (S3) of the other side is also blocked, so that the weak fire power of the first stage This operation is also to control the so that the signal input to the MPU 12 is output to the ratchet circuit 16 to control the necessary solenoid (S1) (S2) (S3).

When combustion starts after setting time and controlling power by electric method, press timer start switch (SW5) to input cooking start to MPU (12), and then set time is counted from this time. An IC relay connecting the electrical signal to the solenoids S1, S2, and S3, which are then amplified by the amplifier 17 via the ratchet circuit 16, and are then closed. By shutting off (I.R1) (I.R2) (I.R3), the supply of gas is stopped and combustion ends, and the thermal sensor 10 fixed to one side of the burner head 2 is This will be detected.

The thermal sensor 10 generates about 14 mV of thermal power after ignition by heat burned by the burner head 2, amplifies the voltage to about 14 V in the amplifier 18, and then generates a voltage generated at the output of the constant voltage regulator 20. By connecting the output to the input terminal of the comparator 13 and outputting a constant value of about 1V with a variable resistor, when the combustion is normally performed in the burner head 2, the comparator 13 compares it immediately and outputs the "L" signal. Accordingly, the transistor Tr is turned on and the signal is transmitted to the MPU 12 so that the alarm sound and the simultaneous combustion stop light blink, so that the user can know the cooking completion.

The timer (8) or clock is operated by the exact cycle generated from the frequency divider (19). In front of the main body (1), the clock operation indicator, the timer operation indicator, the valve fire indicator, etc. together with various operation switches. The left and right sides are exposed to each other, and the operation state of the high pressure generator enables the user to grasp each operation state in detail.

As described above, the present invention is a method of simply contacting various switches of a contactless quench method, and the cooking time is automatically shut off so that the housewife can cook different foods or enjoy leisure activities while cooking. In addition, all functions are automatically processed and displayed by the microprocessor, which is a useful design that can give users convenience and novelty.
