Heating/stirring cooker

A heating/stirring cooker comprising:

• a main body;
• a container that is disposed inside the main body and configured to accommodate an object to be cooked;
• a stirring body that is detachable from the container, the stirring body having a blade for stirring the object to be cooked in the container and a magnet disposed at a position facing an inner bottom part of the container in a state in which the stirring body is disposed inside the container;
• a magnetic field generator that is disposed inside the main body and configured to generate a rotating magnetic field so that a rotational force of the rotating magnetic field acts on the magnet;
• and
• a controller that is disposed inside the main body and configured to control the magnetic field generator,
• wherein:
• the controller is configured to control the magnetic field generator so that:
• (i) a direction of rotation of the rotating magnetic field is switched between a forward rotation direction and a reverse rotation direction that is reverse to the forward rotation direction;
• and (ii) a number M of rotations in the reverse rotation direction is less than a number N of rotations in the forward rotation direction;
• the controller is configured to switch the direction of rotation of the rotating magnetic field, at least either when the rotating magnetic field makes a set number of rotations which has been set in advance for the forward rotation direction and the reverse rotation direction or when a change in a rotational state of the stirring body is detected;
• in a case where the direction of rotation of the rotating magnetic field is switched when the rotating magnetic field makes the set number of rotations which has been set in advance for the forward rotation direction and the reverse rotation direction, a ratio of the number M of rotations to the number N of rotations is within a range from 0.1 to 0.9;
• in the case in which the direction of rotation of the rotating magnetic field is switched when the rotating magnetic field makes the set number of rotations which has been set in advance for the forward rotation direction and the reverse rotation direction, the number M of rotations is within a range from 1 to 2;
• and
• the blade is configured to gather the object to be cooked during rotation in the forward rotation direction and break up the object to be cooked during rotation in the reverse rotation direction.
