In this way, when the microwave oven is heated using the magnetron 13, the end notice is not notified and only the end notification is given. However, except when the magnetron 13 is used to heat the microwave oven, the communication of the wireless communication device 6 is performed by the server 7 and the communication terminal. Since it is connected to No. 8, it is possible to notify the end notice. The end notice is not limited to the remaining 30 seconds, and can be set to a desired time such as 1 minute remaining or 15 seconds remaining. Further, it may be set to give the end notice notification a plurality of times, such as 1 minute remaining and 30 seconds remaining. Further, it may be set so that the end notice notification is not given.

Further, when the communication between the wireless communication device 6 and the server 7 and the communication terminal 8 during cooking is only a notification of the end, the cooking can be performed in any of range heating, oven heating, grill heating, and steam heating. , The communication of the wireless communication device 6 may be disconnected at the start of cooking, and the communication of the wireless communication device 6 may be connected at the time of transmitting the end notice notification signal of the oven heating, the grill heating and the steam heating.

In the present embodiment, the frequency of communication by the wireless communication device 6 is the 2.4 GHz band, but by using the 5 GHz band, which is more than twice this frequency, radio wave interference with the microwave oscillated by the magnetron 13 can be caused. It can be less likely to occur. In this case, the connection and disconnection of the communication of the wireless communication device 6 can be freely selected even during the heating of the microwave oven using the magnetron 13. Therefore, it is preferable that the wireless communication device 6 can be used at any frequency of the 2.4 GHz band and the 5 GHz band.

As described above, the microwave oven 1 of the present embodiment has a first heating means using the magnetron 13, a second heating means not using the magnetron 13, and wireless communication capable of wireless communication with the communication terminal 8. The oven range 1 is heated by including the device 6 and the communication control means 72 for controlling the wireless communication device 6 and enabling wireless communication during a part or all of the heating by the second heating means. Even during cooking, communication connection by the communication terminal 8 is possible at least for a part of time. Further, when the magnetron 13 is not used, communication is performed by the wireless communication device 6, and radio wave interference with the microwave oscillated by the magnetron 13 can be prevented. Therefore, it is possible to prevent the wireless communication by the wireless communication device 6 from becoming unstable or being unable to communicate.

Further, in the microwave oven 1 of the present embodiment, the wireless communication device 6 is capable of wireless communication in a frequency band equal to or more than twice the frequency of the microwave oscillated by the magnetron 13, so that the microwave oven 13 is being heated. Even if there is, communication by the wireless communication device 6 becomes possible.

Further, the microwave oven 1 of the present embodiment includes a main body 2 having a cooking chamber 5 inside and a door 4 for opening and closing the opening 3 of the main body 2, and the wireless communication device 6 is inside the door 4 and is on the lower side. By being arranged in the central portion, the first intake port 50 is arranged on the right side of the position of the wireless communication device 6, and the first exhaust port 51 is arranged on the left side of the position of the wireless communication device 6. By doing so, the first exhaust port 51 can be separated from the first intake port 50. Therefore, it is possible to make it difficult for the high-temperature air discharged from the first exhaust port 51 to be taken into the inside of the door 4 (inside the first flow path 56) from the first intake port 50.

Further, in the microwave oven 1 of the present embodiment, the first flow path 56 and the second flow path 57 for flowing the cooling gas are formed inside the door 4, so that the oven range 1 is cooked by heating. It is possible to suppress the temperature rise of the door 4 and the handle 42 due to the above.

Further, in the cooking cooker system of the present embodiment, the microwave oven 1 includes a current detecting means 74 for detecting a current value during operation of the magnetron 13, and a wireless communication device based on the current value detected by the current detecting means 74. By determining the disconnection of the communication by 6, the communication of the wireless communication device 6 can be disconnected when the magnetron 13 is used.

Further, in the cooking cooker system of the present embodiment, the user heats the oven range 1 by transmitting the heating state information of the oven range 1 from the wireless communication device 6 to the communication terminal 8 during the time when the wireless communication is possible. It is possible to receive a notification of the end of cooking and a notification of the end of cooking, and it is possible to recognize the end of cooking without visually recognizing the microwave oven 1.
