Abstract

PURPOSE:To enable a television cooking program, etc. to be recorded and reproduced by a cooking oven controller equipped with cooking information image- wise displaying means and a control circuit, by selecting signals from a plurality of image signal sources, and permitting them to be inputted into displaying and recording means. CONSTITUTION:Based on the inputs from a key board 3a and a voice recognizing means 23, an interface 20 and an image signal switch-over switch 19 switch over image signals from a nonitor camera 16, a television receiver 17, a VTR 18 and an image signal controlling means 13 to display an arbitrary image on an image displaying means 15. The interface 20 controls the VTR 18, causes an image signal recording means 22 to memorize image signals from a monitor camera 18 and the television receiver 17, and controls reproduction at an arbitrary point. According to this arrangement, cooking programs obtained through television or the monitor camera can be displayed, recorded or reproduced, and therefore the performance concerned can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an open control device for cooking equipped with a pictorial cooking information display means and a control circuit, and an object thereof is to be able to freely record and reproduce image signals from a monitor camera or a television receiver. It is something to do.

Conventionally, the operation setting section of a cooking oven has mainly adopted a digital display means having a segment structure, as typified by a microwave oven.

FIG. 1 shows a part of the operation setting section of a conventional microwave oven equipped with a 4-digit numerical display section having a 7-segment configuration.

In FIG. 1, 1 is a microwave oven main body, 2 is a 7-segment type 4-digit numerical display, and 3 is a keyboard. The operation of such a microwave oven is roughly as follows.

The heating time, heating power, or temperature is set and stored by operating the keys on the keyboard 3. Konoto 37.

The set value is displayed on the four-digit numerical display section 2.

When the microwave oven is in operation, the numerical value displayed on the four-digit numerical display section 2 is counted and increases or decreases over time. When the set time is reached, the count on the display section 2 stops, and heating in the microwave oven is completed. Further, the programmed numerical values can be read out on the display unit 2 and checked if necessary.

The above operation is executed by the microwave oven control circuit shown in FIG.

In FIG. 2, 4 is a control microcomputer, which includes a central processing unit (CPU) and a data storage unit (RAM).
, program storage unit (ROM).

and an input/output control section. Reference numeral 5 represents a power amplifying section for controlling the magnetron 6, and reference numeral 7 represents an interface circuit between the temperature sensor 8 and the microcomputer 4.

As is clear from the above configuration and operation, the means for exchanging information between the microwave oven and the user are the segment type numeric display and the keyboard, and although man-machine matching is not always possible, do not have.

In particular, cooking utensils are devices used to satisfy human sensory needs such as taste and sight, so they are easy to boil.
Ease of handling is a necessary condition.

From this point of view, it is difficult to say that a display means with a segment configuration and about four digits as in the above-mentioned conventional example is necessarily appropriate.

The present invention alleviates the above-mentioned drawbacks and includes a display means and a control circuit that can display more cooking information in the form of images.
Moreover, it is capable of recording and reproducing image signals from monitor cameras and television receivers, making it even more versatile.

In FIG. 3, 9 is a microprocessor, 1o is a main memory section that stores data and programs, and 11
are keyboard 3a, magnetron control section 5. and an open control section consisting of a temperature sensor 8 and a pass line 12
The pass line 12 includes address, data, and input/output control lines.

5. - 13 is an image signal control means, which writes the screen display data transferred via the pass line 12 into the refresh memory 14, and also outputs it to the image display means 16, for example, a cathode ray tube (hereinafter referred to as CRT). Generates image signals for display.

19 is a monitor camera 16. A television receiver 17 selectively switches image signals from a video tape recorder (hereinafter referred to as VTR) 18 and an image signal control means 13 to perform CT
This is a changeover switch means for inputting to 115. 2o
monitor camera 16° TV receiver 17. This is an interface for controlling the VTR18.
R18 is composed of an image signal source 21 and an image signal recording means 22. 23 is a voice recognition means, and a microphone 2

Parameter comparison section 27. It consists of a parameter memory 28, and the output of the voice recognition means 23 is connected to the pass line 12.

The present invention will be explained in detail based on the above configuration.

When the cooking number corresponding to the cooking menu name is input from the 6-basic keyboard 3N, the menu name, cooking data, and material data corresponding to the cooking number are read out from the main memory 1o, and these data including the menu name are read out. The data is arranged so as to be arranged on one screen and is transferred to the refresh memory 14 through the image signal control means f3. Image signal control means 13
, the contents of the refresh memory 14 are CR
Displayed on T15.

When heating starts, the magnetron 6 is operated by the interface 11 and the power control section 6.

As the heating progresses, time is counted and temperature is measured, and the results are transferred to the refresh memory 14 and stored in the C
Displayed on RT15.

The speech recognition means 23 amplifies the speech signal input from the microphone 24 with the speech input section 25, extracts the phonetic features contained in the speech signal with the feature parameter extraction section 26, and converts it into digital data.

This feature parameter extraction unit 26 includes, for example, a filter bank, an analog multiplexer, a five-way converter 7 re
This can be easily realized by frequency spectrum analysis using >−. The parameter comparison section 27 compares the feature parameter group of the voice word registered in advance in the parameter memory 28 with the feature parameter of the unknown speech inputted from the feature parameter extraction section 26, and calculates the distance from each feature parameter group. If the minimum value of the distance is less than or equal to the threshold value, the word corresponding to that parameter is output to the path line 12 as a recognized word.

The interface 2o and the changeover switch means 19 control the monitor camera 16. The television receiver 17° switches the image signals from the VTR 18 and the image signal control means 13 to display an arbitrary image on the (jRTl 5).Furthermore, the interface 2o controls the VTR 18, and displays the images from the monitor camera 16 and the television receiver 17. The image signal can be stored by the image signal recording means 22, and can be reproduced at any time after recording.

As described in detail above, according to the present invention, an image display means such as a CTH is used, and image signals from a monitor camera or a television receiver can be freely recorded and reproduced, and the cooking open function is improved. can be significantly improved.

The record from the monitor camera becomes a record of the so-called home menu, and anyone can learn about home-made cooking know-how. Additionally, the recordings from the TV receiver can be used as simple notes on cooking programs.

By using voice recognition means, you can operate your microwave oven from a distance, and you can easily record your favorite cooking program while watching TV.
