DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained.

In FIG. 1, reference numeral 1 denotes an operation panel which is arranged on the front surface of the main body (not shown) of the high frequency heating apparatus. A display 2 is located above the operation panel 1 using a liquid crystal panel or a fluorescent display tube. Reference numeral 3 denotes a pulse switch for inputting a cooking menu, which is a rotary encoder and is located below the operation panel 1. Reference numeral 4 denotes a key for deleting and returning an unnecessary cooking menu from a large number of cooking menus that can be set by the menu delete / return key, which is provided on the operation panel 1.

In FIG. 2, reference numeral 5 is a control means composed of a microcomputer (hereinafter referred to as a microcomputer), and a CPU (central information processing circuit) via an I / O (input and output) 5a.
5b is coupled, and a storage unit 5c composed of a ROM (read-only storage element) and a RAM (storage element for writing / reading) 5d are coupled thereto, and the pulse switch 3 is rotated normally,
The reverse rotation and the number of input pulses are discriminated, the contents are displayed on the display 2, and the high frequency generating means 7 is controlled.

Further, the ROM 5c of the microcomputer 5 sets a time-measuring means for measuring a time signal from the pulse generating circuit 6 and a cooking menu which is set in advance in accordance with the forward and reverse rotations of the pulse switch 3 and the number of input pulses. A possible cooking menu selection means, a display means for displaying the set cooking menu on the display device 2, a cooking start means for starting cooking by a start signal when the pulse switch 3 is started (for example, pushed), Menu deletion / restore key Deletes unnecessary cooking menus from a large number of cooking menus that can be set by a signal from the menu 4 and deletes the menus. The control means 5 is provided. Further, in the RAM 5d of the microcomputer 5, each cooking menu is temporarily stored with a variable X so that each cooking menu stored in the ROM 5c can be set as shown in FIG. 3a (reference state). There is. A pulse generation circuit 6 is connected to the input side of the microcomputer 5. Reference numeral 7 is a high frequency generating means for heating an object to be heated, which is composed of a magnetron and a drive circuit for driving the magnetron. 8 is menu deletion

The control means 5 is provided in order to enable deleting and restoring an unnecessary cooking menu from the cooking menu which can be set by the cooking menu selecting means.

Next, the operation of the above configuration will be described with reference to FIGS.

FIG. 3 is a conceptual diagram of the processing contents of the microcomputer when the number of cooking menus is deleted, and FIG. 4 is a flowchart of the reference state before the start of cooking.

The flow chart will be described below.

Immediately after the power is turned on, the control means 5 sets the predetermined number of settable cooking menus to the maximum value, and sets the variable X to an initial value in the RAM 5d used for selecting the cooking menu. Further, a cooking menu is assigned for each value of the variable X so that a plurality of automatic cooking menus stored in advance in the ROM 5c can be set. Next, when the pulse switch 3 is turned to the left or right, the variable X is added or subtracted,
The cooking menu assigned according to the value of the variable X is selected, and the setting contents are displayed on the display device 3. However, when the variable X exceeds the maximum value, X = 1 is forcibly set. For example, if the maximum value of the variable X is 7, as shown in FIG.
When it is 0, it is in the standard condition where cooking is not set, and X is set to 1 each time the pulse switch 3 is turned 1 click to the right.
