Inside the gas burner 13 is arranged individually, the front panel 14 is provided with a plurality of control panels 15 for controlling the ignition state and the ignition time of each gas burner (13).

Here, the upper end (13a) of the gas burner 13 is disposed so as to be located below a predetermined depth (H) from the upper surface of the upper plate 11 in the center of the cooking utensil 12, the cooking utensil 12 The container support 16 for placing the food container is placed on each, the top of the container support 16 is provided with a support (16a) is caught on the cooking port 12 of the top plate 11 to support the food container. In addition, a flame guide wall 17 having a height corresponding to the depth H from the upper plate 11 to the upper end 13a of the gas burner 13 is formed at the bottom of the container support 16. have. Accordingly, when the vessel holder 16 is seated on the cooking port 12, the lower end of the flame guide wall 17 extends to the upper end 13a of the gas burner 13 as shown in FIG. .

Therefore, as shown in FIG. 2, when the flame is ejected from the gas burner 13, the flame is guided into the flame guide wall 17 of the vessel holder 16 and seated on the vessel holder 16. Concentrate the flame at the bottom of (a).

Of course, the food container (a) used here is based on the premise to use the one that fits the diameter of the container support 16, a problem for this because a normal type of food container (a) is used in restaurants, etc. It can not be at all, and the gas range and the food container (a) according to the present invention is usually provided integrally, so that this problem can be fundamentally solved.

And, as shown in Figure 2, each of the gas burners 13 are fixedly installed on the support 19 installed across the case 18 of the gas range via the nozzle block 20, the nozzle block. 20 is connected to the fire fire gas pipe 21 for supplying a relatively large amount of gas and the weak fire gas pipe 22 for supplying a relatively small amount of gas, the river fire gas pipe 21 and the weak fire gas pipe (22). 2 is connected to the gas supply pipe 25 through the respective solenoid valves 23 and 24, as shown in FIG.

In addition, the gas burner 13 has a head 28 having a gas injection hole 27 on the upper end of the cylindrical burner body 26 fixed to the nozzle block 20, as shown in FIG.

In addition, the gas range case 18 is provided at the lower end so that the soup tray tray 34 can be pulled out as shown in Figures 1 and 2. When the soup tray 34 has a large number of broths when food is cooked and the broth overflowed from the broth ring 33 is overflowed, the soup tray 34 receives the broth down through the empty space inside the case 18. It is to solve the problem that the case 18 is damaged because of a dirty range or food waste.

And, the tray 34 is pulled out when the soup comes down to be able to clean, so that you can always maintain a clean atmosphere.

In addition, as shown in FIG. 5, the gas burner 13 is provided with an igniter 35 and a temperature sensing rod 36 for generating a fire in a position adjacent to the gas injection hole 27 of the head 28. The temperature sensing rod 36 is ignited by a flame ejected from the gas ejection hole 27 by the spark ejected from the igniter 35. This is to control the state of fire, which will be explained later.

On the other hand, the control panel 15 disposed on the front panel 14, as shown in Figure 6, the cooking time indicator 37, the low and low lamps (38, 39), the power lamp (40), The ignition / nonignition lamps 41 and 42, a flame setting button 43 for selecting strong and low light, a time setting button 44 for setting the time, and an operation / stop button 45 are provided.

Gas range of the present invention having the structure as described above is connected to the configuration as shown in the block diagram of Figure 7, that is, the control unit 46 is connected to the control panel 15 is connected to the power source In addition, the control unit 46 includes an igniter 35 for igniting the gas burner 13, a temperature sensing rod 36 for sensing a flame to sense a temperature, and an opening / closing valve for controlling gas supply.

Is connected to the gas burner 13.

Gas range of the present invention having such a structure, by using the various buttons (43, 44, 45) provided in the control panel 15 to control the required cooking time and the state of the flame by time so that food is automatically cooked. The outline of the control method is as follows.

First, power is applied, large amount of gas is supplied, and the time when a large flame is generated is charged and set the fire time, and a small amount of gas is supplied to store the time when a small flame is generated. Operation step to operate the gas range sequentially in the state of high light and low light according to the time set in the time setting step, time setting step, and stop the operation of gas by stopping the supply of gas after the setting time of the high light and low light And a display step of generating a visual signal by blinking the beep and the lamp after the operation is completed according to the set state.

On the other hand, for ease of use, the time change step for the operator to arbitrarily change the strong and weak fire time in the above operation step as needed, and the ignition of the gas is not made correctly or the gas supply is not smooth to operate normally If not, an alarm can be added to trigger the alarm again.

The process of embodying each step as described above will be explained in connection with the apparatus of the present invention. First, the flame setting is first performed while the power switch 48 provided on one side of the case 18 is turned on to apply power. When the button 43 is pressed once, the strong light lamp 38 is turned on, and the light setting state is set. In this state, the time setting button 44 is selected in the up / down direction and the strong setting time is selected. The time is displayed on the cooking time indicator 37. When the setting button 43 is pressed again in the state indicated by the desired light setting time of the bar 37, the strong light lamp 38 is turned off while the high light setting time is set, and at the same time, the weak light lamp 39 ) Lights up, ready to set the low incombustibility time setting.

The weak incombustibility time setting process is the same as the strong incombustibility time setting process, i.e., after the weak incombustibility time is set, the time setting button 44 is selected in the up / down direction again in the state in which the weak inexpensive lamp 39 is turned on. When the low incombustibility time is selected, the selected time is displayed on the cooking time indicator 37, and when the desired time is displayed on the indicator 37, the setting button 43 is pressed. (39) goes out.

After completing the charging of the weak and weak selection time in this process, press the operation button 45, the power lamp 40 is turned on, the ignition is made to the gas burner 13, and when the initial strong fire state, the strong light lamp ( 38) is turned on, and while the combustion is in a strong fire state, the strong lamp 38 is continuously turned on, the detailed process of igniting the gas burner 13 is as follows.

First, when the operation button 45 is turned on after the strong and weak burn time setting process as described above, the gas open / close valve 24 connected to the light burn gas pipe 22 is opened by a signal generated from the controller 46. Thus, a small amount of gas is supplied to the gas burner 13 so that a small amount of gas is ejected through the gas injection hole 27 formed in the head 28 of the gas burner 13. At the same time, the control unit 46 also applies power to the igniter 35 to generate a spark in the igniter 35, so that a small amount of gas injected through the gas injection hole 27 is ignited.

In the above bar, the gas opening and closing valve 24 connected to the weak fire gas pipe 22, which is supplied with a small amount of gas, is first opened and ignited because the ignition works well when ejected to a small amount of gas. In addition, if the ignition when a large amount of gas is ejected because the smell is due to the gas that is not ignited.

When the small amount of gas emitted from the gas injection hole 27 of the head 28 is ignited in this manner, the temperature of the flame is placed on the temperature sensing rod 36 disposed adjacent to the gas injection hole 27. Is detected and notified to the controller 46 of the ignited state.

After the light is completely ignited, the gas opening and closing valve 23 connected to the strong fire gas pipe 21 is additionally opened to the electrical signal generated by the controller 46 to supply a large amount of gas together. That is, additional gas is supplied to the strong fire gas pipe 21 while the gas is supplied to the weak fire gas pipe 22.

As a result, the flame generated at the head 28 of the gas burner 13 is brought into a fire state, and this fire state continues for the time set in the control panel 15.

After the set fire time set in the control panel 15 has elapsed, the gas opening and closing valve 23 connected to the fire gas pipe 21 is automatically shut off, so that a large amount of gas supplied through the valve 23 is not supplied. The gas is stopped and only the gas supplied through the remaining weak fire gas pipe 22 and the open / close valve 24 is maintained in a weak fire state, and the weak fire state is also maintained for the time input through the control panel 15. After the time has elapsed, the open / close valve 24 connected to the weak fire gas pipe 22 is shut off to stop the supply of gas to be burned.

As such, after maintaining the state of strong fire for a predetermined time, by maintaining the state of the weak fire for a certain time, the food is fully cooked and the unique flavor of the food can be achieved.

Therefore, when using the gas range according to the present invention, even if you do not have an expert on the food to be cooked, you can always have the same taste, even if you know the exact cooking time, especially in large restaurants, etc. It can be used conveniently when you need to cook.

On the other hand, since the food cooking time and the strong / weak light time set through the control panel 15 is stored in the controller 46 is stored, after setting the flame state and time once to do the setting work to be set again again Since there is no need to cook the same kind of food under the same conditions, it can be operated simply by using only the operation / stop button 45.

In addition, there may be a case where the type of food is different from the one set, or the weak dead time may be changed in the middle due to an abnormal operation. In this case, the time setting button ( By pressing 44 again in the up and down direction, it is possible to extend or shorten the strong fire state, and likewise, when the time setting button 44 is adjusted when the low fire state is being operated, the weak fire burning time can be extended or shortened. .

Therefore, the gas range of the present invention can not only cook one type of food but also can easily set and cook several types of food.

In addition, as described above, after setting the weak dead time completely, in the process of igniting by pressing the operation button 45, if the ignition is not completed completely or turned off by an abnormal state after ignition, a signal is generated. In addition to generating a beep sound from the unit 47, all lamps flash at once, indicating that there is an abnormality, and allowing the operator to display the type of abnormality on the cooking time indicator 37 so that the operator can easily take follow-up actions. To be able.

Similarly, the signal generator 47 generates a beeping sound after the completion of cooking of the food, that is, even after the charged time has elapsed, so that the completion of cooking of the food can be grasped from a long distance.

Therefore, when using the gas range according to the present invention, even if the cooker is not attached to the kitchen counter, it is possible to cook many foods at once and deliciously and accurately.

As described above, when using the automatic gas range according to the present invention, by setting the most suitable conditions for cooking to a particular food in advance, even if the cooker is not attached to the countertop even when a large amount of food is to be cooked at once, It can be easily cooked, and it is possible to cook food with the same taste, even if you are not skilled in the food in particular. And the minimum number of people can cook a large number of foods with a certain taste at all times to reduce labor costs, and automatically digests after a certain time, even if you do not watch the food being cooked while doing other work while cooking. Therefore, there is an effect that can prevent accidents due to food burning or gas leakage.

In addition, by using the gas range according to the present invention, there is no problem that the gas range becomes dirty due to the soup and the like generated during food cooking, and the effect that the ignition is made conveniently and accurately can be obtained.

In particular, the gas cooker of the present invention has a structure in which the flame guide wall 17 is formed on the container base 16 so that all the flames generated from the burner 13 are guided to the food container a. It is.
