DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking appliance equipped with a voice recognition function.

2. Description of the Related Art Recently, cooking appliances such as microwave ovens that recognize a user's voice and operate based on the recognized voice have been developed and are being put into practical use. By the way, there are voices of people other than the user around such a microwave oven, and therefore there is a risk that the microwave oven may malfunction.

This invention was made in view of the above circumstances, and its purpose is to provide a highly reliable cooking appliance that can operate reliably without being affected by unnecessary surrounding sounds. It's about doing.

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, reference numeral 1 denotes the main body of a cooking appliance, for example a microwave oven, on the front of which a door 2 is pivotally mounted to be openable and closable, and an operation panel 3 is provided. Then, the main body 1 corresponding to the door 2
A cooking (heating) chamber 4 is provided inside. A rotary shelf board 5 for placing food to be cooked is provided in the cooking chamber 4, and this shelf board 5 is rotatably driven by a motor 6 provided on the back side of the bottom surface of the cooking chamber 4. It's summery. Further, a high frequency generator, for example, an antenna 7a of a magnetron 7 is introduced into the cooking chamber 4, and the antenna 7a is connected to the cooking chamber 4.
High frequencies are now being radiated within the body. On the other hand, the operation panel 3 is provided with a display section 8, a key input switch 9 for manually inputting a cooking program, a transmitter/receiver 10, a cooking switch 11, and a power switch 12 in order from the upper part to the lower part. There is. The transceiver 10 is detachably attached to the main body 1, and has an audio input/output section 10a and an audio input push button 10b on its surface.

Furthermore, 20 is a microcomputer serving as a main control section, to which the display section 8, key input switch 9, relay 21, voice recognition circuit 23, and notification circuit such as a voice synthesis circuit 24 are connected. The relay 21 is provided between the power supply 24 and the voltage transformer 25, and controls the power supply to the magnetron 7 by operating in response to a command from the microcomputer 20. The voice recognition circuit 22 is connected to the transmitter/receiver circuit 3
Audio (audio signal) received from the outside by
It is something that recognizes. The voice synthesis circuit 23 creates a voice signal, which is a notification signal, in response to a command from the microcomputer 20, and transmits it to the outside via the transmitting/receiving circuit 30. Here, FIG. 3 specifically shows the transmitting/receiving circuit 30. As shown in FIG. That is, the transmitting/receiving circuit 30 is
The receiving circuit 31 receives the received signal of this receiving circuit 31.
A detection circuit 32 that performs FM detection, an amplifier circuit 33 that amplifies the audio signal obtained from the detection circuit 32 and supplies it to the audio recognition circuit 22, an amplifier circuit 34 that amplifies the audio signal output from the audio synthesis circuit 23, It consists of a modulation circuit 35 that performs FM modulation on the output of this amplifier circuit 34, and a transmission circuit 36 that transmits the modulated signal obtained by this modulation circuit 35.

By the way, the transmitter/receiver 10 has a transmitter/receiver circuit 4
0, an antenna 40a, and a speaker 50, the speaker 50 converts the input voice into an audio signal, and transmits it to the transmitting/receiving circuit 30 to supply it to the voice recognition circuit 22, and the voice synthesis circuit 23. The transmitter/receiver circuit 30 receives an audio signal emitted from the transmitter/receiver circuit 30, converts it into sound (voice) through the speaker 50, and outputs the sound to the outside. Here, FIG. 4 specifically shows the transmitting/receiving circuit 40. As shown in FIG. That is, the transmitting/receiving circuit 40
These include an amplifier circuit 41 that amplifies the audio signal obtained by the speaker 50, a modulation circuit 42 that modulates the output of the amplifier circuit 41, a transmitter circuit 43 that transmits the modulated signal obtained by the modulator 42, and a receiver circuit 4.
4. A detection circuit 45 performs FM detection on the signal received by the reception circuit 44, and an amplifier circuit 46 amplifies the audio signal obtained from the detection circuit 45 and supplies it to the speaker 50. FIG. 5 shows an example of a transmission system circuit used in the transmitter/receiver 10, in which an audio signal obtained from a speaker 50 is amplified by a transistor 51, and is oscillated by a transistor 52, a coil 53, and a capacitor 54. It is now FM modulated and transmitted.

Next, the operation in the above configuration will be explained.

First, turn on the power switch 12 and
The door 2 is opened, food to be cooked is stored in the cooking chamber 4, and then the door 2 is closed. Then, remove the transceiver 10 from the main body 1, and
While pressing the voice input button 10b, press the voice input section 1.
Towards 0a, the three cooking program setting elements "cooking type", "food type", and "food amount" are described, and the word "cooking start" is stated.
Then, these voices are converted into a series of voice signals and transmitted to the main body 1, which are received by the transmitting/receiving circuit 30 and supplied to the voice recognition circuit 22. In this way, the voice recognition circuit 22 recognizes the uttered voice, and the microcomputer 20 creates a cooking program based on the three cooking program setting elements of the voice. and,
Cooking based on the created cooking program is started by the voice "Start cooking."

In this case, the user will emit sound while holding the transceiver 10 close to his mouth, and even if there are voices other than the user's in the surroundings, he can ignore them and prevent malfunctions. can be prevented. In addition, since the user can cook food remotely from the main unit 1 just by uttering a voice, the user can do other tasks at the same time, which is very convenient especially when used for commercial purposes. .

When cooking starts, the microcomputer 20 commands the voice synthesis circuit 23 to create a voice signal saying "Cooking has started. Please wait for about ○○ minutes x seconds." Transmitted by .30. and,
The transmitted audio signal is received by the transceiver 10,
The audio input/output unit 10a of the transmitter/receiver 10 outputs a voice saying "Cooking has started. Please wait for about xx minutes x seconds." Also, when cooking is finished, the message "Cooking has finished" will be displayed in the same way as above.
The audio is output. Therefore, the user can easily know whether cooking has actually started according to the voice command issued by the user, and furthermore, whether cooking has been completed, even if the user is away from the main body 1.

In the above embodiment, only the case where the transceiver 10 is used after being removed from the main body 1 has been described, but the transceiver 10 can also be used while being attached to the main body 1. Furthermore, the operating status is not limited to voice, but may also be a buzzer sound, and the application is not limited to microwave ovens, but can also be applied to other cooking appliances that have a voice recognition function. . In addition, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without changing the gist.

As described above, according to the present invention, a wireless transmitter/receiver is detachably installed in the main body, and the transmitter/receiver is used to input voice and notify the operating status. It is possible to provide a highly reliable cooker that can operate reliably without being affected.
