receiving rotation speed information of an exhaust fan of the exhaust device from the exhaust device through the short-range wireless communication link;
determining whether a filter included in the flow path needs to be replaced, based on the received rotation speed information; and
displaying a notification indicating that the filter needs to be replaced, based on determining that the filter needs to be replaced.
15. The method of claim 11 , further comprising:
receiving airflow information about a level of an airflow according to the driving of the exhaust device from the exhaust device through the short-range wireless communication link;
determining whether installation of the flow path is abnormal, based on the received airflow information; and
displaying a notification indicating that the installation of the flow path is abnormal.
16. The method of claim 11 , wherein the heating apparatus includes a fine particle sensor configured to sense fine particles in the flow path, and
the transmitting of the operation information to the exhaust device through the established short-range wireless communication link comprises:
detecting an amount of fine particles emitted from a food material through the fine particle sensor;
determining operation information about an output of a fan motor of the exhaust device based on the detected amount of fine particles; and
transmitting the determined operation information to the exhaust device.
17. The method of claim 16 , wherein the fine particle sensor is provided in a buried form in an inner wall of the flow path.
18. The method of claim 16 , wherein the heating apparatus includes a light emitting device, and
the method further comprises turning on the light emitting device based on the detected amount of fine particles.
19. The method of claim 11 , wherein the heating apparatus includes a plurality of aspiration hobs and a plurality of valves corresponding to the plurality of aspiration hobs in the flow path, and
the method further comprises opening at least one of the plurality of valves based on a position of a burner being heated among a plurality of burners in the heating apparatus.
20. The method of claim 11 , wherein the short-range wireless communication link is a first short-range wireless communication link, and
wherein the method further comprises:
establishing a second short-range wireless communication link with a hood device located over the heating apparatus, based on receiving a user input for turning on the heating apparatus; and
transmitting operation information different from the operation information transmitted to the exhaust device to the hood device based on the second short-range wireless communication link with the hood device, according to driving of the heating module.
