System interworking between a cooking apparatus and a kitchen device

A system interworking between a cooking apparatus for cooking food and a kitchen device in communication with the cooking apparatus, the system comprising:

• a cooking apparatus comprising a heat source for cooking food, a first sensing unit sensing operation of the heat source, a first transmitter transmitting an electrical signal to the kitchen device, and a first controller controlling the first transmitter to transmit the electrical signal to the kitchen device based on the first sensing unit sensing the operation of the heat source;
• and
• a kitchen device comprising a fan that is configured to suck odor of food cooked by the heat source, a second receiver receiving the electrical signal transmitted by the first transmitter, and a second controller controlling the driving of the fan according to the electrical signal received by the second receiver,
• wherein the first sensing unit is a thermo-couple configured to generate an electromotive force by being heated by heat energy of the heat source, and the first controller is configured to control the first transmitter to transmit the electrical signal to the second receiver based on the electromotive force generated by the thermo-couple.
