The present invention relates to a gas oven, in particular, if the grill burner is extinguished after a predetermined time after driving the gas oven stove grill burner or the cavity door is not opened, the grill burner is automatically extinguished to burn food in cooking. The present invention relates to a method for automatically extinguishing a gas oven stove grill burner.

In general, a gas oven is a cooking apparatus that combines a conventional gas stove for cooking food and an oven for putting food into a cavity and cooking food using radiant and convective heat.

3 is a view showing the gas oven as described above, the gas oven stove is located on the upper portion of the gas oven stove used for cooking food, such as soup and the lower portion of the stove burner (1) The oven burner 3, which is mounted in the cavity 4 located in the upper part, is used to cook foods such as bread, and the grill burner 2 used to cook foods such as fish.

However, the grill burner used for cooking food such as fish is supplied with gas through a mechanical valve, so that the user needs to ignite or extinguish the grill burner by directly operating the grill burner ignition switch in order to use the grill burner.

Therefore, when the user puts food into the cavity and cooks the food, if the user does not adjust the grill burner ignition switch to extinguish the grill burner, the grill burner continues to operate in a continuous mode. There is a problem.

Accordingly, the present invention has been made to solve the above problems, and if the grill burner is not extinguished or the cavity door is opened after a predetermined time since the grill burner of the gas oven is driven, that is, the new food is a cavity It is an object of the present invention to provide a method of automatically extinguishing a gas oven stove grill burner by automatically extinguishing the grill burner so as to prevent cooking or burning of cooking food.

In order to achieve the above object, the present invention, in the grill burner control method applied to the gas oven, the first step of the user to set the maximum use time of the grill burner, the maximum of the grill burner in the first step If the use time is set, the combustion mode is performed according to the operation of the grill burner ignition switch, and the second step of determining whether the maximum use time of the grill burner has ended, and if the maximum use time of the grill burner is finished in the second step, the grill burner The third step of determining whether the cavity door is opened or closed if the maximum use time of the grill burner is not finished, and resetting the maximum use time of the grill burner and opening or closing the cavity door if the cavity door is opened or closed in the third step. If the grill burner ignition switch is off, And a fifth step of extinguishing the grill burner if the grill burner ignition switch is turned off in the fourth step and determining whether the maximum use time of the grill burner has ended if the grill burner ignition switch is not turned off. do.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing the configuration of a gas oven range to which the present invention is applied. The gas oven range includes a timer 10 for counting the maximum use time of a grill burner set by a user, and a grill for controlling the operation of the grill burner. A first solenoid valve 60 driven by an operation of a burner ignition switch 20 and the grill burner ignition switch 20 to supply gas to a pilot burner, and supplied by the first solenoid valve 60. An ignition transformer 80 for igniting gas, a second solenoid valve 70 for supplying gas to the grill burner, a salt voltage detector 50 for detecting the salt voltage of the grill burner, and an open / closed state of the cavity door The door switch 30 which detects is provided.

2 is a flowchart of a grill burner automatic fire extinguishing control method applied to the gas oven range configured as described above.

First, the user opens the cavity door, puts food to be cooked in the cavity, adjusts the timer 10, sets the maximum burn time according to the food to be cooked, and then turns on the grill burner ignition switch 20. The controller 40 drives the timer 10 to start counting, and also drives the first solenoid valve 60 to supply gas to the pilot burner, and simultaneously drives the ignition transformer 80 to supply gas to the pilot burner. Ignite (101-106).

When the pilot burner is ignited, the controller 40 drives the second solenoid valve 70 to supply gas to the grill burner (107). Therefore, the gas supplied to the grill burner is ignited by the flame of the pilot burner.

On the other hand, the controller 40 compares the salt voltage of the grill burner detected by the salt voltage detector 50 with the reference voltage and stops driving the ignition transformer when the detected salt voltage is greater than the reference voltage (108 to 110).

While the grill burner is in the combustion mode as described above, the control unit 40 determines whether the count of the timer 10 has ended, and if the timer has expired, the maximum use time of the grill burner has ended, so that the first and second solenoid valves 60 70 to block the gas supplied to the pilot burner and the grill burner (111, 115).

On the other hand, if the count of the timer 10 is not finished, the controller 40 determines whether the cavity door is opened or closed (112). If the cavity door is opened or closed, that is, new food is put into the cavity, the maximum use time of the grill burner according to the food to be cooked is reset, and if the cavity door is not opened or the maximum use time of the grill burner is reset, the control unit 40 The grill burner ignition switch 20 determines whether (OFF) (113, 114).

When the grill burner ignition switch 20 is turned off, the controller 40 drives the first and second solenoid valves 60 and 70 to block the gas supplied to the pilot burner and the grill burner, and the grill burner ignition switch 20 If it is not off, it is determined whether the maximum use time of the grill burner has ended (115, 111).

As described above, according to the present invention, if the grill burner is extinguished after a predetermined time after driving the grill burner of the gas oven, or the cavity door is not opened, the grill burner is automatically extinguished to burn food in cooking or a fire occurs. Can be prevented.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
