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 input settings are entered into a microcomputer 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 perform more precise cooking, but it also has the disadvantage of requiring more input operations using keys, etc., making it less user-friendly.

Therefore, as a method to overcome these drawbacks, a method has already been proposed in which a cooking sequence corresponding to a specific cooking menu is stored in advance in a semiconductor memory, and the sequence is recalled and executed by the user's voice. . However, in this method, as the number of cooking menus increases, it is conceivable that there will be many similar cooking menus in terms of audio signals, and therefore there is a possibility of erroneous settings.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object of the present invention is to provide a highly reliable and easy-to-use cooking device that eliminates the above-mentioned disadvantages of setting cooking sequences using the user's voice. It is something. In particular, when the user sets the cooking sequence of a predetermined cooking menu by voice, the name of the cooking menu is displayed in text at the same time, thereby realizing a cooking device that does not cause erroneous settings due to voice. .

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.

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

6 is a microphone through which the user inputs the cooking menu name by voice.

FIG. 2 is a block diagram showing the configuration of an actual control circuit. Reference numerals 7 and 8 denote first and second microcomputers, which are 4-bit one-chip microcomputers.

First, the first microcomputer 7 implements the following tasks using a control program.

Controls the number display section 4a.

Processes input signals from the keyboard 5.

ROM in advance according to the cooking menu code sent from the second microcomputer 8.
The cooking sequence stored in the cooking sequence is automatically set, and the heating device 11 is controlled based on the cooking sequence.

Next, the second microcomputer 8 shares the following tasks.

Controls the character display 4b.

The code signal corresponding to the cooking menu output from the voice recognition means 9 is decoded to search for the cooking menu, and the cooking menu name is displayed on the character display 4b, and the first microcomputer 7 is instructed to display the cooking menu. Transmit the code.

The work controlled by the two microcomputers mentioned above is mainly carried out by the microcomputer's control program, and is difficult to visualize in practice. However, if their functions are shown in a block diagram, It will look like Figure 3.

That is, first, when the user speaks the cooking menu name into the microphone 6, the voice signal is converted into feature parameters by the voice input means 10 and input to the voice recognition means 9. The voice recognition means 9 stores a plurality of voice characteristic parameter data indicating pre-registered cooking menu names, and compares it with the signal input from the voice input means 10. As a result, if a matching item is found among the plurality of feature parameter data with a certain degree of matching, a code signal corresponding to the matching item is output to the cooking menu search means 12.

The cooking menu search means 12 searches for a corresponding cooking menu from the contents of the input code signal, and displays the name of the cooking menu in text.
A predetermined address is given to the character display data memory 13, and a predetermined cooking menu code is also transmitted to the cooking control means 14.

The cooking control means 14 calls a pre-stored cooking sequence based on the sent cooking menu code, executes it, controls the heating device 11, and displays the progress etc. on the numerical display section 4a. indicate.

Also, the characteristic parameters of the input audio signal are
When the data does not match the data stored in advance in the voice recognition means 9, the voice recognition means 9 transmits another code signal that does not correspond to the cooking menu to the cooking menu search means 12. The cooking menu search means 12 gives a predetermined address to the text display data memory in order to display the information "There is no corresponding cooking menu" to the user in text.

With the above configuration, when the user speaks the name of a cooking menu into the microphone, the cooking sequence for that cooking menu is automatically set, and the name of the cooking menu is displayed in text form. Since feedback is provided to the user, a highly reliable cooking device with no erroneous settings can be realized.

Claims (1)

[Claims] 1 A voice input means including a microphone compares the voice signal input from the voice input means with voice data indicating a cooking menu name registered in advance, and selects a predetermined cooking menu name. a voice recognition means that recognizes that a voice input indicating a message has been received and outputs a code signal corresponding to the voice input; and a cooking menu that searches for a cooking menu based on the code signal output from the voice recognition means. a search means, a character display for displaying in character the cooking menu searched by the cooking menu search means, and a character display for displaying the searched cooking menu from among a large number of pre-stored cooking sequences; A cooking appliance characterized by comprising cooking control means for automatically selecting and setting a cooking sequence. 2. When the voice signal input from the voice input means is different from the voice data indicating a cooking menu registered in advance in the voice recognition means, a character display indicates that the corresponding cooking menu is not registered. The cooking device according to claim 1, characterized in that the information is displayed in the form of letters.
