Abstract

Disclosed herein is a cooking apparatus. The cooking apparatus includes a cooking plate, a plurality of induction heating coils installed under the cooking plate, a plurality of drivers configured to supply driving power to the plurality of induction heating coils, and a controller configured to control the plurality of drivers to drive a plurality of groups to which the plurality of induction heating coils belong, respectively. Power output by a first driver, among the plurality of drivers, which drives a first group among the plurality of groups may be increased and power output by a second driver, among the plurality of drivers, which drives a second group among the plurality of groups may be decreased.

First claim

What is claimed is:

1 . A cooking apparatus comprising:
a cooking plate; a plurality of induction heating coils installed under the cooking plate; a plurality of drivers configured to supply driving power to the plurality of induction heating coils; and a controller configured to control the plurality of drivers to drive a plurality of groups to which the plurality of induction heating coils belong, respectively, wherein power output by a first driver, among the plurality of drivers, which drives a first group among the plurality of groups is increased and power output by a second driver, among the plurality of drivers, which drives a second group among the plurality of groups is decreased.

2 . The cooking apparatus of claim 1 , further comprising:
a user interface configured to receive information about output of the cooking apparatus from a user, wherein the controller is configured to identify a total power output by all the plurality of drivers based on the information about output of the cooking apparatus.

3 . The cooking apparatus of claim 2 , wherein the controller is configured to assign the plurality of groups to the plurality of drivers and identify power output by each of the plurality of drivers based on a number of the plurality of induction heating coils belonging to each of the plurality of groups.

4 . The cooking apparatus of claim 3 , wherein the power output by each of the plurality of drivers is not proportional to the number of the plurality of induction heating coils belonging to the each of the plurality of groups.

5 . The cooking apparatus of claim 1 , wherein the controller is configured to identify offset power to regulate power output by the first driver and the second driver.

6 . The cooking apparatus of claim 5 , wherein the controller is configured to identify the offset power based on a total power output by all the plurality of drivers.

7 . The cooking apparatus of claim 5 , wherein the controller is configured to identify the offset power based on a difference between the power output by the first driver and the power output by the second driver.

8 . The cooking apparatus of claim 5 , wherein the power output by the first driver is increased by the offset power and the power output by the second driver is decreased by the offset power.

9 . The cooking apparatus of claim 1 , wherein the controller is configured to divide control of the plurality of induction heating coils into the plurality of groups, respectively, and
induction heating coils, among the plurality of induction heating coils, are divided into the first group and the second group based on positions of the induction heating coils which overlap with a position of a cookware placed on the cooking plate.

10 . The cooking apparatus of claim 9 , wherein the first group includes an induction heating coil, an entirety of which overlaps with the position of the cookware and the second group includes an induction heating coil, at least portion of which is outside the position of the cookware.

11 . A method of controlling a cooking apparatus having a plurality of induction heating coils installed under a cooking plate, the method comprising:
identifying induction heating coils among the plurality of induction heating coils based on a plurality of groups to which the plurality of induction heating coils belong, respectively; supplying, by a plurality of drivers, driving power to the plurality of groups of the plurality of induction heating coils, respectively, wherein power output by a first driver, among the plurality of drivers, driving a first group among the plurality of groups is increased and power output by a second driver, among the plurality of drivers, driving a second group among the plurality of groups is decreased.

12 . The method of claim 11 , wherein the supplying, by the plurality of drivers, of the driving power to the plurality of groups comprises:
assigning the plurality of groups to the plurality of drivers, respectively; and identifying power output by each of the plurality of drivers based on a number of the plurality of induction heating coils belonging to each of the plurality of groups, and wherein the power output by each of the plurality of drivers disproportional to the number of the plurality of induction heating coils belonging to the each of the plurality of groups.

13 . The method of claim 11 , further comprising:
identifying offset power to regulate power output by the first driver and the second driver.

14 . The method of claim 13 , wherein the identifying of the offset power comprises identifying the offset power based on a total power output by all the plurality of drivers.

15 . The method of claim 13 , wherein the identifying of the offset power comprises identifying the offset power based on a difference between the power output by the first driver and the power output by the second driver.

16 . The method of claim 13 , further comprising:
increasing the power output by the first driver by the offset power; and decreasing the power output by the second driver by the offset power.

17 . The method of claim 11 , wherein induction heating coils among the plurality of induction heating coils, are divided into the plurality of groups, respectively, based on positions of the induction heating coils which overlap with a position of a cookware placed on the cooking plate.

18 . The method of claim 17 , wherein the first group includes an induction heating coil, an entirety of which overlaps with the position of the cookware and the second group includes an induction heating coil, at least portion of which is outside the position of the cookware.

19 . A cooking apparatus comprising:
a cooking plate; a plurality of induction heating coils installed under the cooking plate; a first driver and a second driver configured to supply driving power to the plurality of induction heating coils; and a controller configured to control the first driver and the second driver to respectively drive induction heating coils belonging to a first group and a second group to which the induction heating coils among the plurality of heating coils belong, wherein a ratio of power output by the first driver and power output by the second driver is different from a ratio of a number of induction heating coils belonging to the first group and a number of induction heating coils belonging to the second group.

20 . The cooking apparatus of claim 19 , wherein the first group includes an induction heating coil, an entirety of which overlaps with the cookware and the second group includes an induction coil, at least portion of which is outside a position of a cookware placed on the cooking plate.
