Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a high-frequency heating device in which cooking time information for high-frequency heating cooking is inputted by key operation.

(Prior Art) Conventionally, in a high-frequency heating device using a microcomputer (abbreviated as microcomputer), such as a microwave oven, when inputting food cooking command information, cooking time information and heating output (high-frequency output) information have to be operated using separate keys. I was trying to input it by

(Problems to be Solved by the Invention) Therefore, when cooking is performed by switching the cooking time and heating output many times, key operations become extremely complicated.

In addition, in the time cooking mode in which food is cooked for a set cooking time, the input set time is a guideline, and the completion time generally varies considerably depending on the weight of the cooked food and the amount of water content. Therefore, even if the time is entered in seconds or minutes, it is not very meaningful for ordinary foods.

This invention was made in view of the above-mentioned circumstances, and it is possible to input cooking time information and heating output information at once with a single key operation, or input cooking temperature information in the case of temperature cooking mode. The purpose of the present invention is to provide a highly convenient high-frequency heating device that enables the user to easily input cooking information.

(Function) In the time cooking mode, the cooking time value and heating output value assigned to one operated key are taken in as cooking information for high-frequency heating cooking. In the temperature cooking mode, the food temperature value assigned to the operated key is taken in as cooking information for high-frequency heating cooking.

(5 minutes to 60 minutes) sequentially every 5 minutes, and assign a heating output value (100 watts to 600 watts) to each key along the remaining direction, that is, the horizontal axis direction.
The food temperature value (100°C to 200°C) is assigned sequentially every 100 watts, and some of the keys, for example, the two keys at the bottom, are assigned food temperature values (100°C to 200°C).
℃) are assigned sequentially every 10℃.

In this case, the cooking time value can be assigned in seconds or units.
Although the units are 5 minutes instead of minutes, and the heating output values are assigned in units of 100 watts, these units can be arbitrarily selected; for example, in units of 100 watts.
If you often use minutes to 15 minutes, it is possible to set it in units of 1 minute.

Further, around the keyboard 5, an output indicator light 6 corresponding to the heating output allocation, a time indicator 7 to display the set time, a cooking start button 8, and a cooking indicator light 9 to indicate that cooking is in progress. , a sensor indicator light 10 indicating that the mode is temperature cooking mode (food temperature is being detected by a temperature probe to be described later), and a mode changeover switch 20 for switching between time cooking mode and temperature cooking mode. ing.

FIG. 3 shows a specific circuit of the microcomputer control mechanism shown in FIG.
