Description

  The present invention relates to an induction heating type cooking device in which a cooking menu can be added or changed.

  For example, an induction heating electric rice cooker (IH type) currently on the market is generally equipped with a microcomputer in its control unit, such as water absorption, rice cooking amount determination, cooking, boiling maintenance, cooking detection, unevenness, etc. Each of the rice cooking processes having a plurality of rice cooking processes, the heat insulation process having a plurality of heat insulation processes such as low temperature insulation (64 ° C), glossy and long-lasting insulation (67 ° C), high temperature insulation (72 ° C), etc. There are many foods that can be cooked deliciously and kept warm by controlling with high accuracy and power at a proper heating temperature within a proper time every time.

  Control of the rice cooking or heat retaining function in such an electric rice cooker is executed in accordance with the process program written in the ROM as the control program storage means (control data storage means) of the microcomputer. Yes.

  However, in any conventional general-purpose microcomputer electric rice cooker, the contents of the process program are written by the manufacturer, and the program data once written cannot be rewritten (patent) Reference 1).

  Therefore, the actual situation is that the user has to use the cooked rice or the heat retaining function specified by the contents of the program data at the time of purchase until the next replacement, such as an electric rice cooker without a burnt rice cooker function. It was not possible to add a rice cooking menu that would add a charred rice cooking function.

  In view of such circumstances, recently, by adopting a rewritable storage means as the microcomputer-side control data storage means of the rice cooker body, and using this as a menu data storage means, the control program can be rewritten once. Also proposed is a rice cooking or warming menu that can be added or changed after purchase. As another method, for example, the menu data storage means can be replaced with a replaceable packaging type data memory such as a memory card so that the menu can be added or changed. is there.

  On the other hand, recently it is not necessary to monitor cooking conditions like gas-fired ones, and it is easy to control the pressure with a microcomputer or timer, so the pressure state can be controlled accurately and easily. Hereinafter, simply referred to as an electric pressure cooker) is attracting attention.

  Such an electric pressure cooker can be widely used for various cooking menus such as (1) boil, (2) steam, (3) cook, (4) boil, etc. Since cooking is performed at a high temperature, potatoes such as “meat potatoes” can be sufficiently cooked, and hard “shin meat” can be cooked softly in a relatively short time. Therefore, the meat potato is suitable for various stewed cooking including various cooked dishes such as curry and stew (see Patent Document 2).

  However, in the conventional electric pressure cooker, there is no automatic cooking menu for such various stewed cooking, and after the pressure cooking is finished, the user must perform stewed cooking according to the material while adjusting the heating by manual operation. did not become.

  Under such circumstances, it is desired to realize an automatic stewed cooking menu that includes an original pressure cooking process and a subsequent stewed cooking process, which can be performed automatically and sequentially. And when such a stewed automatic cooking menu is implement | achieved, expansion | deployment of the various different stewed cooking menu using the pressure function is anticipated.

  Therefore, in such an induction heating type electric pressure cooker, as in the case of the induction heating type electric rice cooker, for example, a new cooking menu provided from a manufacturer's homepage using the Internet or the like is used as menu data storage means. It is conceivable that the automatic cooking menu can be added or changed by downloading the data or by replacing the menu data storage means with a replaceable packaging type data memory such as a memory card. Each of these cooking menus can be prepared from various viewpoints. For example, it is assumed that Japanese, Western, elderly, children and other various items are provided.
