Abstract

A user interface for an induction heating cooker, a method of controlling the same and an induction heating cooker thereof are provided. The user interface, if a drag touch signal of a drag touch from one position to another position on a display unit is sensed, is configured to change power levels of all of coils in operation to a predetermined reference power level and displays the changed power level. The induction heating cooker is configured to supply the coils with a power corresponding to the reference power level, thereby controlling all of the coils with one drag touch and enabling enhanced security while in a rapid manner.

First claim

What is claimed is:

1. A user interface for an induction heating cooker, the user interface comprising:
a display including a display screen configured to display a power level of a coil in operation; and
a sensor configured to sense a touch signal that is input through a position randomly selected in the display screen,
wherein if the sensor senses a first drag touch signal corresponding to a single continuous drag touch from one position of the display screen to substantially an opposite end of the display screen in a first orientation with respect to the display screen corresponding to a setting of a power level, the display uses a single display screen to set power levels of all coils in operation to a predetermined standard level, and
wherein if the sensor senses a different drag touch signal in a second orientation with respect to the display screen substantially perpendicular to the first orientation, a cooking time is adjusted.

2. The user interface of claim 1 , wherein if the sensor senses a second drag touch signal through the display screen, the display sets power levels of all of the coils in operation to individual power levels provided at a time when the first drag touch signal is sensed.

3. The user interface of claim 2 , wherein the second drag touch is performed in an opposite direction to the first drag touch.

4. The user interface of claim 1 , wherein if the sensor senses the different drag touch signal corresponding to a drag touch from one position to another position of the display screen, cooking times of all coils in operation are adjusted to a predetermined standard cooking time.

5. The user interface of claim 4 , wherein if the sensor unit senses a second drag touch signal through the display screen, the display sets power levels of all of the coils in operation to individual power levels provided at a time when the first drag touch signal is sensed, and
wherein if the sensor senses a drag touch signal in an opposite direction to the different drag touch signal, the display adjusts cooking times of all of the coils in operation to individual cooking times provided at a time when the different drag touch signal is sensed.

6. The user interface of claim 1 , wherein the predetermined standard level is an off power level.

7. An induction heating cooker comprising:
a user interface configured to display power levels of all of coils in operation at a predetermined standard level, if a drag touch signal corresponding to a drag touch from one position to another position of a display including a display screen is sensed at a position randomly selected in the display screen; and
a controller configured to change power levels of all of the coils in operation to the predetermined standard level if the drag touch signal is sensed as moving from one position of the display screen to substantially an opposite end of the display screen in a first orientation with respect to the display screen corresponding to a setting of a power level and to adjust a cooking time if the drag touch signal is sensed as moving in a second orientation substantially perpendicular to the first orientation.

8. The induction heating cooker of claim 7 , wherein the user interface, if another drag touch signal is sensed after sensing the drag touch signal, displays the power levels of all of the coils in operation to individual power levels that are provided before the power levels of all of the coils in operation are changed, and
the controller, if the user interface senses the other drag touch signal after sensing the drag touch signal, changes the power levels of all of the coils in operation to the individual power levels provided before the power levels of all of the coils in operation are changed.
