Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control/operation device for an automatic heating cooker that automatically controls cooking using a microcomputer or the like.

Conventional example of 柘戊 and its problems A combination of a microcomputer and a famous Sesisa that detects temperature, humidity, etc.
This has made it possible to automatically cook food using heating cookers such as electric ovens and electric cookers.

In other words, in the past, it was possible to perform several types of cooking with one type of heating procedure, but now the heating output can be changed or intermittent over time, or the heating time can be changed depending on the temperature of the object to be heated or the change in water vapor. By adding different heating procedures to each of the famous dishes, such as freely extending or shortening the cooking time, it is now possible to cook more deliciously and with fewer mistakes.

The cooking itself is automated, which is very convenient as it saves you the trouble of controlling the heat and other tasks during cooking.In conventional automatic cookers, there are keys on the control panel to select 15 to 20 cooking options. Because the cooking keys are arranged in such a way that it is extremely troublesome to flip the corresponding cooking keys, and as the number of keys increases, the size of the keys and the display characters become relatively small, making it difficult to read, difficult to operate, and prone to erroneous operation. It was a flaw.

High-frequency heating cooking has the advantage of heating food in a short time, and in reality it is most often used as a microwave oven, but it is also used for reheating cooking that takes advantage of this advantage and reheating cold rice, miso soup, etc. .

Automation of this reheating process has also progressed, making it possible to automatically cook food regardless of the amount or type of food.

On the other hand, it is now possible to automate single-dish dishes such as cakes, breads, meat and fish dishes, etc. For these, it is advantageous to choose a self-heating method that shortens the cooking time. This can be called cooking that is used infrequently.

The fact that frequently used cooking keys and infrequently used cooking keys are treated equally and arranged on the operation panel in this way also contributes to the difficulty of use.

2. It is unreasonable that the cooking keys are arranged in such a way that it takes time to turn them up before the short cooking time of 3 minutes.

If the frequently used cooking keys are placed larger and closer together, the number of other less frequently used cooking keys must be reduced, and even though the microcomputer has sufficient control capability, the display and operation space is limited. However, there was a drawback in that it limited the number of automatic cooking operations.

OBJECTS OF THE INVENTION It is an object of the present invention to overcome the above-mentioned conventional drawbacks, and to provide an automatic heating cooker having cooking selection keys arranged in an easy-to-read and easy-to-operate manner without reducing the number of cooking selection keys. With the goal.
