Abstract

A cooking apparatus is provided. The cooking apparatus includes a first manipulation part, a second manipulation part, an electric heating element for heating an object to be cooked, a switch connected with a relay that is turned on/turned off, and which is for providing power provided through the relay in a turned-on state to the electric heating element according to a user manipulation input through the first manipulation part, and a processor which, based on receiving input of a user manipulation of the second manipulation part, turns on the relay for a predetermined time period.

First claim

What is claimed is:

1. A cooking apparatus comprising:
a first manipulation part;
a second manipulation part;
an electric heating element configured to heat an object to be cooked;
a first switch configured to be operated by the first manipulation part and positioned between a first live power line and the electric heating element;
a second switch configured to be operated by the first manipulation part and positioned between the electric heating element and a relay, the relay being configured to be in one of an on state or an off state, the second switch being configured to provide power from a second live power line through the relay in the on state to the electric heating element according to a user manipulation of the first manipulation part; and
a processor configured to:
based on receiving an input of a user manipulation of the second manipulation part, turn on the relay for a predetermined time period,
based on receiving the input of the user manipulation for the second manipulation part, determine a manipulation state of the first manipulation part,
based on determining that the first manipulation part is in a turned-off state, turn on the relay from a turned-off state for the predetermined time period, and
based on not receiving input of the user manipulation of the first manipulation part in the predetermined time period, turn off the relay after the predetermined time period passes.

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 second 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 , 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.

4. 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.

5. The cooking apparatus of claim 4 , 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.

6. 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.

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

8. 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.

9. The cooking apparatus of claim 8 , 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.

10. A cooking device comprising:
a plurality of electric heating elements configured to provide heat to an object;
a first switch configured to provide power from a first power source and a second switch configured to provide power from a second power source to the at least one of the plurality of electric heating elements;
a relay configured to, based upon actuation to provide power from the second power source to the second switch;
at least one knob configured to, based on a rotation of the at least one knob when the first switch and the second switch are in an off state, control the first switch and the second switch to be set in an on state; and
at least one processor configured to:
receive an input from a user interface to provide power to the at least one of the plurality of electric heating elements,
determine a current setting of the relay,
based on the relay being set in an off state, set the relay to an on state to provide power from the second power source to the switch,
based on receiving the input of a user manipulation for the user interface, determine a manipulation state of the knob,
based on determining that the knob is in a turned-off state, turn on the relay from a turned-off state for a predetermined time period, and
based on not receiving input of a user manipulation of the knob in the predetermined time period, turn off the relay after the predetermined time period passes.
