a processor configured to, based on receiving input of a user manipulation of the second manipulation part, turn on the relay for a predetermined time period.

2. The cooking apparatus of claim 1,

wherein the first manipulation part includes a knob configured to control the on state or the off state of the switch by rotation according to the user manipulation, and

wherein the switch is further configured to, based on being turned on according to the user manipulation of the knob, provide the power provided through the relay in the on state to the electric heating element.

3. The cooking apparatus of claim 2, wherein the processor is further configured to:

based on receiving the input of the user manipulation for the second manipulation part, determine a manipulation state of the knob, and

based on determining that the knob is in a turned-off state, turn on the relay from a turned-off state for the predetermined time period, and turn off the relay after the predetermined time period passes.

4. The cooking apparatus of claim 2, further comprising:

a speaker,

wherein the processor is further configured to, based on receiving an input of a user manipulation of the knob while the user manipulation of the second manipulation part is not input, control the speaker to output a warning sound or a voice message guiding a manipulation of the second manipulation part.

5. The cooking apparatus of claim 2, wherein the processor is further configured to:

based on receiving an input of the user manipulation of the second manipulation part, determine a manipulation state of the knob, and

based on determining that the knob is in a rotated state, maintain the turned-off state of the relay.

6. The cooking apparatus of claim 5, wherein the processor is further configured to, based on the user manipulation for the second manipulation part being input while the knob is in a rotated state and the knob in the rotated state is set to a turned-off state according to the user manipulation within the predetermined time period, turn on the relay from the turned-off state.

7. The cooking apparatus of claim 2, wherein the processor is further configured to:

based on receiving the input of the user manipulation of the second manipulation part, determine a manipulation state of the knob, and

based on determining that the knob is in a rotated state, turn on the relay from a turned-off state.

8. The cooking apparatus of claim 2, wherein the processor is further configured to:

based on receiving the input of the user manipulation of the second manipulation part while the electric heating element operates, maintain an operation of the electric heating element regardless of the input user manipulation.

9. The cooking apparatus of claim 2, further comprising:

a third manipulation part receiving an input of a user manipulation of a child lock function, and

wherein the processor is further configured to;

based on receiving the input of the user manipulation for activating the child lock function through the third manipulation part, activate the child lock function, and

based on receiving the input of the user manipulation of the second manipulation part while the child lock function is activated, turn on the relay during the predetermined time period.

10. The cooking apparatus of claim 9, wherein the processor is further configured to, based on the child lock function being activated, maintain a door for opening and closing a cooking space of the cooking apparatus in a locked state.

11. A controlling method of a cooking apparatus comprising an electric heating element for heating an object to be cooked, the controlling method comprising:

based on receiving an input of a user manipulation of a second manipulation part, turning on a relay of the cooking apparatus for a predetermined time period; and

providing power through the relay in a turned-on state to the electric heating element according to a user manipulation of a first manipulation part.

12. The controlling method of claim 11,

wherein the first manipulation part includes a knob for controlling turning-on/turning-off state of a switch of the cooking apparatus by rotation according to the user manipulation, and

wherein the providing comprises, through the switch which is turned on according to the user manipulation of the knob, providing the power to the electric heating element.

13. The controlling method of claim 12, wherein the turning-on comprises:

based on receiving the input of the user manipulation of the second manipulation part, determining a manipulation state of the knob; and

based on determining that the knob is in the turned-off state, turning on the relay from the turned-off state for the predetermined time period, and which further comprises;

turning off the relay after the predetermined time period passes.

14. The controlling method of claim 12, further comprising:

based on receiving an input of the user manipulation of the knob while the user manipulation of the second manipulation part is not input, outputting a warning sound or a voice message guiding a manipulation of the second manipulation part.

15. The controlling method of claim 12, further comprising:

based on receiving the input of the user manipulation of the second manipulation part, determining a manipulation state of the knob; and

based on determining that the knob is in a rotated state, maintaining a turned-off state of the relay.

16. The controlling method of claim 15, further comprising:

based on the user manipulation of the second manipulation part being input while the knob is in a rotated state and the knob in the rotated state set to a turned-off state according to the user manipulation within the predetermined time period, turning on the relay from the turned-off state.

17. The controlling method of claim 12, further comprising:

based on receiving the input of the user manipulation of the second manipulation part, determining a manipulation state of the knob; and

based on determining that the knob is in a rotated state, turning on the relay from a turned-off state.
