Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a block circuit diagram according to an embodiment of the present invention. The present invention forms an air inlet and outlet through a vent port not shown, and a fan motor 19 in which an exhaust fan is built on the outlet. And by installing the lamp 21 at the bottom of the range hood to illuminate the surroundings and to send smoke and other vaporized substances generated from the range side through the open surface of the hood door to the exhaust port in the process to filter the impurities in the process It is.

According to an embodiment, the fan motor 19 and the lamp 21 can be controlled by a voice command, and the lamp is opened and closed at the same time by opening and closing the opening by a voice recognition control means having a voice command to be described later. Control 21 to illuminate the surroundings.

The voice recognition control means has a microphone 10 for receiving a voice command for controlling the rotation angle of the fan motor 19, the microphone 10 is basically a microphone having a directivity to remove noise It is preferable to use it, and it is desirable to install it as close as possible to the user's mouth position. The speaker voice command input from the microphone 10 is amplified to a predetermined level through the amplifier 11 and input to the central controller 12. Here, the same voice command may be embedded so that the lamp 21 may be interlocked by the voice command for controlling the fan motor 19.

The audio signal input to the amplifier 11 is amplified to a predetermined level through the first amplifier 11a, and then passes only the intermediate frequency band through the band pass filter circuit 11b, and then through the automatic gain circuit 11c. After the gain is selectively controlled according to the change of the speaker's voice signal, the central controller 12 is inputted to the central controller 12 in a stabilized state while being amplified by a predetermined level through the second amplifier 11d and the buffer 11e. ) To recognize the correct speaker tone.

The central controller 12 trains the amplified speaker voice command and compares the voice command with the voice command pre-stored in the memory unit 13, and outputs a control signal corresponding to the input voice command if it matches any one of the stored voice commands. The motor 19 and the lamp 21 are controlled.

The memory unit 13 stores a trained voice command and stores a source code, a control code, a technology code, and a voice recognition weight according to the voice command.

Furthermore, the central control unit 12 is not limited to any particular person, and has a function of distinguishing a plurality of tones. For example, when the user changes, the central controller 12 distinguishes the tones of the changed user, and the fan motor 19 by the speaker command. ) And the lamp 21.

In addition, the present invention includes a display lamp 14 that emits light when the speaker's voice command is not recognized by the system and the fan motor 19 and the lamp 21 are not controlled. 19 and the lamp 21 is not operated, and includes a load control method selection unit 15 for controlling the fan motor 19, the lamp 21 and other loads by manual operation.

The load control method selector 15 may control the fan motor 19 by selecting and controlling a voice signal and a manual switch 18 signal, for example, different from a preset pattern by ambient noise. Emergency control device that can control not only the fan motor 19 but also other loads through the signal of the manual switch 18 when the voice command is not recognized due to a change in tone or winding, or when a circuit error occurs. to be.

Accordingly, the load control method selector 15 has a manual switch 18 and a voice command circuit connected in parallel, as shown, and the manual switch 18 is directly connected to a power line to connect the fan motor 19. It is desirable to design the circuit so that it can be controlled.

In addition, the present invention further includes a reset unit 16 which maintains an initial state, that is, a fan motor stopped state when the fan motor 19 is stopped without a separate control signal. When the load is stopped by the fan motor 19, the system detects this and is designed to initialize.

In the figure, reference numeral 20 denotes a speaker. When the speaker does not recognize a speaker's voice command, for example, too small a command or when ambient noise and a command sound are mixed and input, the speaker 20 is used again. The guide voice is sent to try, and the guide voice is made under the control of the central controller 12.

The control method of the present invention having such a configuration will be described with reference to FIG. In the power-on state, the system is initialized (S1), i.e., a plurality of sampled voice commands and a fan motor 19 control command are input to the memory unit 13. In the central control unit 12, the microphone If the ambient noise is severe (S2-S3) is determined through (10), and if the ambient noise is severe, the voice guidance sound is transmitted (S4) that the voice command cannot be recognized due to the noise. When the voice control command of the motor 19 is input (S5), the central controller 12 recognizes the voice pattern of the speaker and compares the voice patterns stored in the memory unit 13 (S6-S7).

If one of the stored voice patterns and the input speaker's voice pattern match, the central controller 12 controls the fan motor controller 17 to energize or cut off the power applied to the fan motor 19. Let's go.

On the other hand, if the voice pattern of the speaker is not recognized in step 7, retry is performed through voice guidance. In this case, the central controller 12 transmits various voice guidance (S11).

For example, if the command tone is too small to recognize it, speak louder. On the contrary, if the command tone is too loud, speak softly or if the ambient noise is too loud, it cannot be recognized due to noise. The guide voice is transmitted in various forms such as to induce the speaker's voice command again, and the guide voice is re-transmitted according to the result (S12).

In addition, the embodiment has been described with reference to the command sound for the rotation and stop of the fan motor 19, but as another example, the fan speed by the voice command that can be distinguished in step by step the rotational speed of the fan motor 19 and the operation reservation time In addition to controlling the motor 19, the on / off voice command of the lamp 19 matches the on / off voice command of the fan motor 19 so that the fan motor 19 and the lamp 21 have the same voice. It is desirable to be controlled by the command.

Speaker voice commands according to an embodiment of the present invention are a motor motor rotation (Motor Rotation), a motor motor stop (Motor Stop), the rotation speed (Set Position), the rotation speed increase (Tilt Up), the rotation speed decrease (Tilt Down) ), The operation reservation time (about 10-30 minutes), and the like, and the system controls the fan motor according to the voice commands. In the embodiment, the fan motor rotation and fan motor stop commands are executed. It is applied to the on / off control of the lamp 21 at the same time.

On the other hand, the speaker voice commands are controlled by operating the relay by outputting an electrical signal when the corresponding voice command is recognized, in this case, all of the commands are different, but the electrical signals output after recognizing any one command is the same. The same behavior occurs in succession of other commands.

In other words, the fan is rotated so that the fan is controlled while the fan motor is rotating, either the 'stop' command or 'speed up' command is used to control the relay with 'stop' or 'speed up' or the same electrical signal. The motor stops during rotation.

In view of this point, in the embodiment of the present invention, it is necessary to operate the fan motor by software, and therefore, it is necessary to distinguish between commands that cannot be followed by commands that can follow each voice command.

For example, logic can be configured to disallow a 'stop' command after a 'increase fan motor' command to distinguish between commands that can follow each voice command and commands that cannot follow.

You can do this in your assembly program by doing the following:

MSB

/ / step down / tilt Down / tilt Up / set position / Motor Rotation / Motor Stop /

LSB

Motor Rotation /

b＿tilt＿Down equ 11h; 00010001b Initial state

b＿tilt＿Up equ 60h; 01100000b

b＿step＿down equ 70h; 01110000b

b＿Motor＿Rotation equ 07h; 00000111b

b＿Motor＿Stop equ 15h; 00010101b

b＿set＿position equ 11h; Initial state

When the instruction bit is allocated to 8 bits and the instruction is filled from the LSB, the total of 7 instruction bits is set to 1, which can be recognized in the current state and 0 for the unrecognized instructions in the current state.

As described above, the present invention can provide convenience in use by allowing the exhaust hood of the range hood to be controlled by a voice command. Furthermore, by applying voice commands for the fan's rotation and stop to lighting, the load can be controlled with a minimum of commands.
