Cooker

1. A cooker comprising:

a heating chamber in which an object to be heated is placed on a placing table used also as a bottom surface thereof;

a detachable heating pan which is detachably provided inside the heating chamber and on which an object to be heated is placed which is different from the object to be heated;

a high-frequency wave supply unit which generates microwaves;

an antenna which radiates the microwaves generated by the high-frequency wave supply unit;

a heat supply unit which heats the object to be heated placed on the heating pan by heat radiation different from the microwave heating; and

a control unit which controls heating treatment of the objects to be heated

wherein when a first object to be heated is placed on the placing table used also as the bottom surface of the heating chamber, and a second object to be heated is placed on the heating pan, the control unit controls the second object to be heated so as to be heated by the heat supply unit after subjecting at least the first object to be heated to the microwave radiation, and stops operation after heating of the objects to be heated is completed.

2. The cooker according to claim 1 , comprising:

a steam supply unit which heats the object to be heated by steam,

wherein the control unit controls to heat the first object to be heated or the second object to be heated by the steam supply unit.

3. The cooker according to claim 2 ,

wherein the control unit performs a control to drive the steam supply unit so as to add heating by steam at a predetermined time after the second object to be heated begins to be heated by the heat supply unit.

4. The cooker according to claim 2 ,

wherein the control unit performs a control to drive the steam supply unit so as to supply steam temporarily, during the heating of the second object to be heated by the heat supply unit.

5. The cooker according to claim 2 ,

wherein the control unit performs a control to lower the output of microwaves before the second object to be heated begins to be heated by the heat supply unit so as to continue microwave heating, and to drive the steam supply unit to add heating by steam while the output of microwaves is lowered.

6. The cooker according to claim 2 ,

wherein the control unit performs a control to drive the steam supply unit to add heating by steam after the stop of the heating by the heat supply unit, and to complete the heating of the object to be heated and stop operation.

7. The cooker according to claim 1 , comprising:

a notification unit,

wherein the control unit performs a control to stop the microwaves from the high-frequency wave supply unit temporarily, and to drive the notification unit at the stop.

8. The cooker according to claim 1 , comprising:

a hot-air supply unit which supplies a hot blast to the heating chamber,

wherein the control unit performs a control to drive the heat supply unit and the hot-air supply unit alternately so as to add heating after microwaves are radiated.

9. The cooker according to claim 1 ,

wherein the heat supply unit comprises an optical heater, and

wherein the control unit performs a control so that the second object to be heated is heated by the optical heater.

10. The cooker according to claim 9 ,

wherein the optical heater is a steam transmissive heater.
