1. A control method of an appliance including a first unit that has a first cavity, a first door and a first sensor; a second unit that has a second cavity, a second door and a second sensor; and at least one controller, the control method comprising:
sensing, by the first sensor and the second sensor, vibrations in at least one of the first unit or the second unit;
determining, by the at least one controller, whether the sensed vibrations are caused by a knock;
based on determining that the sensed vibrations are caused by the knock, generating, by the at least one controller, respective knock-on signals for the first unit and for the second unit;
comparing, by the at least one controller, the knock-on signals for the first unit and for the second unit,
determining, by the at least one controller and based on comparing the knock-on signals for the first unit and for the second unit, which one of the first unit or the second unit received the knock; and
controlling, by the at least one controller, the one of the first unit or the second unit that received the knock,
wherein the vibrations are generated at one of the first door or the second door, and the first sensor or the second sensor connected to the first or second doors respectively via, a transfer member to receive the vibrations from the first or second doors respectively.
