Description

[0001] Control method of electric cooker [0002]

The present invention relates to a method of controlling an electric heating cooking appliance, and more particularly, to a method of controlling an electric heating cooking appliance which allows a secondary cooking operation to be performed only when a lid is opened.

BACKGROUND ART [0002] In recent years, electric pressure cookers for household use have been widely used due to their convenience in use.

This electric pressure cooker can be used easily because anyone can easily cook rice by connecting a power source with a predetermined rice and water in an inner pot and pressing a cooking key.

The conventional electric pressure cooker is provided with a safety device for preventing continuous cooking by the malfunction of each component. The conventional safety device measures the temperature of the inner pot through the bottom sensor and informs the user that the inner pot will be continuously cooked when the temperature of the inner pot reaches a predetermined temperature or more. However, continuous cooking by the malfunction of the program is not checked by the bottom sensor, so continuous cooking can not be prevented.

Korean Patent Publication No. 2006-0071264

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric heating cooking appliance control method capable of preventing a device from being damaged by a continuous cooking operation due to a program malfunction.

According to an aspect of the present invention, there is provided a method of controlling an electric heating cooking apparatus, including a first cooking step for performing a first cooking step, a sensing step for sensing opening of a lid, And a second cooking step of advancing the second cooking step when the second cooking step is inputted.

In the sensing step, the opening of the lid can be sensed through the magnetic force acting between the lid and the body.

In the sensing step, when the lid is opened for a predetermined time or more, the user can be informed of the opening of the lid.

According to the method for controlling an electric heating cooking appliance of the present invention as described above, the following effects can be obtained.

The secondary cooking process is performed only when the lid is opened, so that the device can be prevented from being damaged by continuous malfunction due to program malfunction. It is also possible to prevent the food being cooked through the device from being in an inedible state such as being pressed, burned or dried.

In the sensing step, the opening of the lid is sensed through a magnetic force acting between the lid and the body, so that the opening of the lid can be accurately detected with a simple configuration.

In the sensing step, when the lid is opened for a predetermined time or more, the user is informed of the opening of the lid to prevent foreign matter from entering the inside of the cooking appliance or damaging the food inside the cooking appliance.

1 is a schematic front view of an electric cooking appliance according to a preferred embodiment of the present invention.
2 is an open schematic diagram of an electric cooking appliance lid according to a preferred embodiment of the present invention.

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

For reference, the same components as those of the conventional art will be described with reference to the above-described prior art, and a detailed description thereof will be omitted.

1 and 2, the electric cooking device of the present embodiment includes a main body 300 on which an inner pot is placed, a lid (not shown) rotatably installed on the main body 300 through a hinge, And a lid opening sensing unit 800 for sensing the opening of the lid 900. [

The electric heating cooker of this embodiment is an electric heating pressure cooker such as an electric pressure cooker.

The lid open sensing part 800 is sensed through the magnetic force acting between the lid 900 and the main body 300. [

The lid open sensing unit 800 includes a magnet 810 installed in the main body 300 and a magnet switch 820 installed in the lid 900 to sense the magnet 810. [

The magnet 810 is installed on the upper surface of the main body 300 and is arranged close to the front of the main body 300. [ The magnet 810 is disposed outside the inner pot.

The magnet switch 820 is disposed on the lower surface of the lid 900 and is disposed outside the clean cover.

The magnet 810 and the magnet switch 820 are arranged to correspond when the lid 900 is closed.

When the lid 900 is closed, the magnet switch 820 senses the magnet 810 and the lid 900 is detected as being closed.

When the lid 900 is opened, the magnet 810 is not detected by the magnet switch 820 and the lid 900 is detected as being opened.

The control unit receives a signal from the lid opening sensing unit 800 and controls a display unit including a heating unit such as an induction heating unit or a display unit or a light emitting unit.

Further, the cooking device of the present embodiment further includes a timer, and notifies the user when the lid 900 has been open for a predetermined time or longer.

Hereinafter, the electric cooking device control method of the present embodiment having the above-described configuration will be described.

The control method of the electric heating cooking apparatus of the present embodiment includes a first cooking step for performing a first cooking step, a sensing step for sensing opening of the lid 900, and a second cooking step when the lid 900 is opened And a second cooking step of advancing the second cooking step if the second cooking step is inputted.

The control unit senses the opening of the lid 900 through the lid open sensing unit 800 after the first cooking step.

Opening of the lid 900 is detected through the magnetic force acting between the lid 900 and the main body 300.

If the lid 900 has been opened at least once after the first cooking step, the controller determines whether or not the second cooking process has been input. The input of the secondary cooking process may be input by the user through the input unit on the display unit or may be inputted by the program malfunction.

The control unit proceeds to the secondary cooking step when the secondary cooking step is inputted.

That is, if there is an input of the secondary cooking process after the lid 900 is opened after the primary cooking process, it is determined that the input is normal, and the controller performs continuous cooking.

If the secondary cooking process is not inputted, the process returns to the step after the sensing step.

If the second cooking process is input while the lid 900 is not opened after the first cooking step, the controller determines that the second cooking process is an input due to a malfunction, . That is, the controller does not proceed with the second cooking process even if the second cooking process is input in a state where the lid 900 is not opened after the first cooking process. Then, the control unit notifies the display unit or the display unit of the occurrence of a malfunction.

Further, the controller senses the open time of the lid 900 through the timer. When the lid 900 is opened for a predetermined time or more, the controller informs the user of the opening of the lid through the display unit or the display unit.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
