Abstract

PURPOSE:To improve maneuverability of a cooker provided with a self-operating unit, by constituting a heating cooker with a key board such that a heater is regulated through control of a microcomputer by means of a key board input signal. CONSTITUTION:With a key board 5 controlled, a cooking menu is inputted to a microcomputer 15 through a converter 16. This outputs an output signal according to a program previously stored in the microcomputer 15, a relay coil 18 is operated via a converter 17, and a magnetron 12 is actuated via a relay 8, a high-voltage transformer 9, a capacitor 10, and a diode 11 to control a heating. This constitution causes the microcomputer to perform an automatic control solely through selection control of the key board 5, which results in improving maneuverability.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating cooker equipped with a keyboard.

BACKGROUND ART A heating cooker has been put into practical use that has a configuration in which a heating cooking method is stored in advance in a microcombi cooker and automatically performs heating suitable for the food. This eliminates the need to set the heating time each time, making it easy to use, and by performing heating most suitable for the object to be heated, it is possible to improve the finished product.

The present invention was invented in order to make a heating cooker equipped with such an automatic device more convenient and easy to use, and will be described by way of an example implemented in a high-frequency heating device.

FIG. 1 is a perspective view showing the external appearance of a heating cooker according to the present invention, and a door 2 is provided on the front surface of a main body 1 so as to be openable and closable. Reference numeral 3 denotes an operation panel, which includes a display section 4 and a keyboard 6. FIG. 2 is a circuit diagram of a heating cooker according to the present invention.
Connect to. The high voltage transformer 9 has a capacitor 10. Connected to magnetron 12 via diode 11.

13 is a control board, to which power is supplied by a low voltage transformer 14. A microcomputer 16 is provided on the control board 13 and connected to the keyboard 5 via a converter 16.

The converter 16 converts the signal from the keyboard 5 into a signal for the microcomputer 3-page computer 15. The microcomputer 16 displays the contents of this signal on the display section 4. In response to a signal from the keyboard 6, the microcomputer 16 outputs an output signal according to a pre-stored program, and the output signal is sent to the relay coil 1 via a converter 17.
8 to open and close the relay contact 8.

FIG. 3 is a partially peeled perspective view of the structure of the keyboard of the heating cooker according to the present invention, in which electrodes A22 are provided on the substrate 21, and each electrode is connected to an external lead wire 23 by printed foil. It is connected. It is bonded to an electrode plate B25 having an electrode B (not shown) via an insulating sheet 24. The insulating tart 24 has an opening 2e, and the electrode A2
2 and electrode B face each other with this opening 26 in between. 2
Reference numeral 7 denotes a display sheet, on whose surface the names of keys 28 and the like are printed and displayed in correspondence with each electrode. By pressing each key 28, the corresponding electrodes A and B become conductive, thereby generating a signal. Key 28Fi displays "Cancel", "Start", and other cooking menus. The display sheet 27 is attached to and detached from the keyboard body using an adhesive, so that it can be peeled off or attached using static electricity.

FIG. 4 is a partial perspective view showing the external appearance of the heating cooker according to the present invention, in which a display section 33 is provided on the operation panel 32 of the main body 31. A display sheet 34 is attached to the surface of the keyboard. The display sheet 34 is shown in a partially peeled state.

Reference numeral 34' denotes an alternative display sheet, on which names of different dishes are printed within the range of menus that can be cooked under the same heating conditions. For example, potatoes and sweet potatoes, miso soup and soup, etc. It also displays dishes that have different names depending on the region, such as oden and Kanto ni. The display sheets 34 and 34' can be freely replaced as needed. Note that the keys are placed in the same position, so even if the keyboard is replaced, the keyboard will still send the specified signals to the microcomputer.

Page V According to the heating cooker according to the present invention, by selecting the menu key corresponding to the display on the keyboard, the cooking time, heating output by ridge connection, etc. can be automatically adjusted according to the program stored in the microcomputer. Since it is done automatically, it saves you the trouble of setting each time, and you can easily heat and cook. Moreover, by setting the optimum program for the food to be cooked, the food will always be cooked in the same way under the optimum conditions, resulting in better and more uniform cooking results.

Furthermore, since the display sheet is removable and replaceable, the user can select the menu according to his or her preference, allowing a wider variety of foods to be cooked, increasing user satisfaction. . In addition, food often has different names depending on the region, but by changing the labels, users can use labels that are familiar to them, making them more familiar and easier to use.

Also, the same menu can be used more widely if it is available in various languages, such as Japanese and foreign languages. Furthermore, even with the same menu name, by changing the color and display design, it is possible to create a heating cooker that perfectly matches each user's preferences, making cooking more enjoyable. It has a simple structure and has many effects.

Furthermore, although the embodiments of the present invention have been described using a high-frequency heating device as an example, the same effects can be achieved even if the heat source is changed, such as one using electric heat or one using combustion of gas or the like.
