Description

DETAILED DESCRIPTION OF THE INVENTION Recently, cooking appliances that use microcomputers to program complex cooking sequences and can cook with the optimal cooking sequence for each cooking menu are becoming popular. For example, a microwave oven is an example of such a cooking device. Generally, in such a microwave oven, the operation for programming the cooking sequence is to input data such as heating power, cooking temperature, and heating time by operating keys and knobs corresponding to each content. The settings are entered into a computer and executed, and by combining these key operations, fairly complex cooking sequences can be programmed. However, as the cooking sequence becomes more complex, it has the advantage of being able to cook more precisely, but it also has the disadvantage of requiring more input operations using keys, etc., making it less user-friendly. .
Therefore, as a way to improve these shortcomings,
A method has been developed, in which a cooking sequence for each cooking menu is stored in advance on a magnetic card, and the contents are inputted to a microcomputer from a magnetic card input/output device and executed as needed, and some methods have been commercialized.

The present invention relates to the improvement of such a magnetic card type cooker, and in particular, in order to clearly inform the user of which cooking menu the data input from the magnetic card belongs to, the magnetic card type cooker is improved. Along with the cooking sequence data, text display data such as cooking menu names are stored on the top of the cooker, which can be read out and displayed in text form on the text display, creating an easy-to-use cooking device that is free from erroneous operation. It is intended to.

Another purpose is to write and store unique cooking sequences created by the user, such as home menus, on a magnetic card, so that if you wish to use it later, you can also write text display data for the cooking menu name at the same time. Therefore, it is an object of the present invention to provide a convenient cooking device that allows easy identification of cooking sequence data on a magnetic card.

EMBODIMENT OF THE INVENTION Hereinafter, the present invention will be explained based on drawings of an embodiment in which the present invention is used in a microwave oven.

FIG. 1 is a perspective view of the exterior, and 1 is the main body of the vessel;
2 is a door installed in the front that can be opened and closed freely,
Food placed in the heating chamber can be seen through the see-through window. Reference numeral 3 designates an operation panel similarly provided on the front side of the vessel, on the surface of which a display section 4 for displaying time, characters, etc., and a keyboard 5 are arranged. Reference numeral 6 denotes a magnetic card input/output device, which inputs and outputs data to and from the magnetic card 7.

Details of the magnetic card 7 are shown in FIG. The magnetic card 7 is composed of a colorless and transparent hard vinyl chloride board having a magnetic storage section 8 and a timing mark section 9. The timing mark section 9 is made by printing a black stripe on a colorless and transparent hard vinyl chloride board, and is for synchronizing with the data stored on the magnetic storage section 8. The magnetic storage section 8 includes at least a header section 10 and a character display data storage section 1.
1. Consists of a cooking sequence data storage section 12, to which a magnetic film of about 8 μm is firmly adhered by heat fusion or the like.

The display unit 4 further includes a numeric display 4a for displaying time such as cooking time and time, and a character display 4 for displaying cooking menu names and the like in text form.
b, consisting of a fluorescent display tube, a liquid crystal display,
This is realized using electronic displays such as LEDs, plasma displays, and cathode ray tubes (CRTs).

The keyboard 5 is realized by using mechanical contacts, conductive rubber, or touch-type keys using human body capacitance, and controls heating power, cooking temperature, and cooking time. In addition to the program setting keys that allow program setting such as, keys for generating arbitrary character display data are provided separately or in combination with the above program setting keys. (However, these contents are not explained in detail in the drawings.) Next, FIG. 3 is a block diagram showing the configuration of an actual control circuit. Reference numerals 13 and 14 are first and second microcomputers, and the control circuit can be constructed at low cost by using 4-bit one-chip microcomputers.

First, the first microcomputer 13 executes the following tasks using a control program.

Controls the numeric display 4a.

Processes input signals from the keyboard 5.

This implements a cooking control means that takes in the cooking sequence transferred from the second microcomputer 14, controls the heating device 15 based on it, and executes cooking. or,
The cooking time and the like are displayed on the numerical display 4a.

Next, the second microcomputer 14 performs the following tasks.

Controls the character display 4b.

Data input from the magnetic card input/output device 6 is taken in via the interface circuit 16. Import the character display data.
Based on the character display data, the cooking menu name and the like are displayed in character form on the character display 4b, and the cooking sequence data is transferred to the first microcomputer 13.

Via the first microcomputer 13,
Cooking sequence data input from the keyboard 5 and character display data such as cooking menu names are transferred to the magnetic card input/output device 6 via the interface circuit 16, and the data are written on the magnetic card 7.

The magnetic card input/output device 6 includes a magnetic head 17,
Read amplifier 18, light amplifier 19, LED 2
0, photo transistor 21, photo amplifier 22
It is composed of etc.

The data on the magnetic storage section 8 read by the magnetic head 17 is amplified by the read amplifier 18 and inputted to the second microcomputer via the interface circuit 16.

Conversely, data output from the second microcomputer 14 is input to the write amplifier 19 via the interface circuit 16, and the data is sent to the magnetic head 1.
7 is driven and written to the magnetic card 7.

The LED 20 and the phototransistor 21 are located corresponding to the timing mark section 9 on the magnetic card 7, and a timing pulse is generated by passing the black stripe on the timing mark section 9, and the timing pulse is generated by the passage of the black stripe on the timing mark section 9. The data above will be synchronized.

With the above configuration, the cooking sequence data can be read from the magnetic card 7, and character display data such as cooking menu names can also be read and displayed in character form on the electronic character display 4b. When the magnetic card input/output device 6 is inserted, the name of the cooking menu for the magnetic card 7 is immediately displayed electronically, making it easy to check whether the magnetic card 7 is the one you intended. The cooking menu name will be displayed only when the magnetic card 7 is inserted correctly, so you can immediately check whether the magnetic card 7 has been inserted.Furthermore, you can also use your own cooking software such as the home menu to display the cooking sequence. By storing the cooking menu name at the same time, misuse of the magnetic card 7 can be prevented, and a reliable cooking device without erroneous operation can be realized.

In addition, a unique cooking sequence programmed by the user can be stored on the magnetic card 7 using the keyboard 5.
At the same time, the cooking menu name can also be written on the magnetic card 7, so when you use that magnetic card later to input a cooking sequence, you will know which cooking menu it is. Since it can be easily identified, a very convenient cooking device can be realized.
