Cook top, range hood and control methods thereof

1. A range hood comprising:

an exhaust fan configured to discharge indoor air to outdoors through an exhaust pipe;

a communicator configured to communicate with a cook top;

an inputter;

a display; and

a processor configured to:

based on receipt of a control signal from the cook top, control an operating state of the exhaust fan to correspond to an operating state of a heating element included in the cook top, and

control the communicator to transmit state information of the range hood to the cook top,

wherein the processor is further configured to:

perform pairing with the cook top in response to receiving a pairing command input through the inputter, and

control the display to display an indicator to indicate, through the display, that the range hood is in a paired state with the cook top after the pairing with the cook top is completed.

2. The range hood according to claim 1 , wherein the processor is further configured to:

based on the receipt of the control signal indicating a start of operation of the cook top from the cook top, control the exhaust fan to start operation of the exhaust fan, and

based on a receipt of a second control signal indicating a stop of the operation of the cook top from the cook top, control the exhaust fan to stop the operation of the exhaust fan.

3. The range hood according to claim 1 , wherein the processor is further configured to:

identify, based on the control signal, a power level of the heating element; and

control an operating intensity level of the exhaust fan based on the identified power level.

4. The range hood according to claim 1 , wherein:

the communicator comprises a Bluetooth module configured to communicate with the cook top in a Bluetooth method, and

the Bluetooth module is disposed at an end of a lower portion of the inputter and the display not to overlap with the inputter and the display.

5. The range hood according to claim 1 , the range hood further comprising:

a light unit configured to provide light to the cook top,

wherein the state information of the range hood comprises information on at least one of an operating state of the exhaust fan, an operating intensity level of the exhaust fan, and an operating state of the light unit.

6. The range hood according to claim 1 , wherein:

the processor is further configured to control the communicator to transmit the state information of the range hood to a portable device through the cook top, and

the portable device is configured to display the state information of the range hood.

7. The range hood according to claim 1 , the range hood further comprising:

a sensor,

wherein the processor is further configured to, based on smoke being sensed through the sensor, control the exhaust fan to operate.

8. The range hood according to claim 7 , wherein the processor is further configured to, based on the smoke being sensed through the sensor, control the communicator to transmit, to a portable device through the cook top, information for notifying a user of the portable device of the smoke being sensed.

9. A method for controlling a range hood communicating with a cook top, the method comprising:

performing pairing with the cook top in response to receiving a pairing command input;

displaying an indicator to indicate that the range hood is in a paired state with the cook top after the pairing with the cook top is completed;

based on receiving a control signal from the cook top, controlling an operating state of an exhaust fan of the range hood to correspond to an operating state of a heating element included in the cook top; and

transmitting state information of the range hood to the cook top,

wherein the controlling the operating state of the exhaust fan comprises discharging indoor air to outdoors through an exhaust pipe.

10. The method according to claim 9 , wherein the controlling the operating state comprises:

based on receiving the control signal indicating a start of operation of the cook top being received from the cook top, controlling the exhaust fan to start operation of the exhaust fan, and

based on receiving a second control signal indicating a stop of the operation of the cook top from the cook top, controlling the exhaust fan to stop the operation of the exhaust fan.

11. The method according to claim 9 , further comprising:

identifying, based on the control signal, a power level of the heating element; and

wherein the controlling the operating state comprises controlling an operating intensity level of the exhaust fan based on the identified power level.

12. The method according to claim 9 , further comprising:

performing pairing with the cook top in response to receiving a pairing command input; and

displaying an indicator to indicate that the range hood is in a paired state with the cook top after the pairing with the cook top is completed.

13. The method according to claim 9 , wherein:

the range hood further includes a light unit to provide light to the cook top, and

the state information of the range hood comprises information on at least one of an operating state of the exhaust fan, an operating intensity level of the exhaust fan and an operating state of the light unit.

14. The method according to claim 9 , wherein:

the transmitting comprises transmitting the state information of the range hood to a portable device through the cook top, and

the portable device is configured to display the state information of the range hood.

15. The range hood according to claim 9 , the method further comprising:

based on smoke being sensed through a sensor of the range hood, controlling the exhaust fan to operate.

16. The method according to claim 15 , the method further comprising:

based on the smoke being sensed through the sensor, transmitting, to a portable device through the cook top, information for notifying a user of the portable device of the smoke being sensed.
