In the conventional combined cooker in which the left and right stoves 2, 3 have the same maximum power, the maximum power of the left and right stoves 2, 3 is the predetermined total maximum power of the equipment. Since it is less than half, even if only one of the left and right stoves 2 and 3 is used, there is a problem that a strong heating power cannot be obtained due to the above restriction, a long cooking time is required, and cooking on high heat is not deliciously finished. there were.

Further, in a product in which the maximum thermal power, that is, the maximum electric power of only one specific one of the left and right stoves 2, 3 is made larger than the other, strong fire (high electric power) can be obtained by the one having the larger maximum thermal power. Depending on the layout of the kitchen, on the other hand, there may be a case where it is desired to cook high heat, and in such a kitchen, it was very difficult to use if a stove capable of high heat was fixed.

In addition, the stove with the largest maximum heat power uses high heat (high power) at first, and then weak heat (low power) when boiled.
While cooking (boiled food etc.) to keep warm at
If you want to cook other high heat (high power), it is very inconvenient because you cannot use it unless you move the pot to the other when the heat becomes low (low power).

For example, an operation will be described when it is necessary to preferentially cook fried rice while cooking curry. In addition, the stove with the largest maximum heat is the left stove 2,
The smaller stove is the right stove 3.

First, place a pan for curry on the left stove 2 with a large maximum heat, stir the meat and vegetables that are the ingredients of the curry with the maximum heat, then add water, and when boiling, set the heat to medium heat and add the curry roux. In addition, stir, and when boiling again, stir on the way while cooking on low heat for a long time.

Since it is necessary to preferentially make fried rice when the meat and vegetables, which are the ingredients for curry, are fried with the maximum heat power, I try to make fried rice. Since you have to use the left stove 2, which has the largest firepower, instead of the small right stove 3, move the pan containing the curry cooked on the left stove 2 to the right stove 3, and then use the left stove 2 for fried rice. It requires a cumbersome cooking procedure in which the pot is placed, the ingredients are added and the ingredients are fried.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a combined heating cooker which enables the left and right stoves to be used with the same high thermal power, that is, high electric power, and which is remarkably improved in usability.
