<Effect of the third embodiment>
According to this third embodiment, one of the following effects can be obtained.
(1) According to this embodiment, in the cooking appliance 86, the cooking management method of the food F to be cooked can be realized by information processing by a computer.
(2) According to this cooking appliance 86, the cooking management system and the cooking management program provide the same effects as in the first embodiment.
(3) The safety of the food F to be cooked in the cooking appliance 86 can be enhanced.

[Other embodiments]
(1) In the above embodiment, the sound collector 26 is used as a means for acquiring acoustic information from the food F to be cooked or the comparative food Fr. may be used to acquire a specific tone color from the cooking object F or the comparative cooking object Fr.
(2) In the above-described embodiment, the control unit 42 may be provided with a filter function for selecting acoustic information for identifying the reference temperature from the food F to be cooked or the comparative food to be cooked Fr.
(3) In the above embodiment, a reference temperature is set for the internal temperature of the food F to be cooked, and it is determined whether the internal temperature has reached this reference temperature. A reference temperature may be set for and it may be determined whether the internal temperature has reached this reference temperature.
(4) In the second embodiment, the timer 34 (FIG. 9) is installed outside the control unit 42, but the timer 34 may be realized by a computer that constitutes the control unit 42. FIG.

As described above, the most preferable embodiment of the present invention and the like have been described. The invention is not limited to the above description. Various modifications and changes are possible for those skilled in the art based on the gist of the invention described in the claims or disclosed in the detailed description. It goes without saying that such modifications and changes are included in the scope of the present invention.

According to this invention, the internal temperature of the object to be cooked can be determined from the acoustic information using the comparison information acquired from the comparative object to be cooked having the same attribute as the object to be cooked, and the internal temperature measurement of the object to be cooked can be speeded up. Reliability can be improved.
