Voice-activated control system for range hood and stove

Abstract

This invention discloses a voice-activated control system for a range hood and a stove, comprising a range hood, a voice receiving module, a first controller, a first wireless communication module, a stove, a second wireless communication module, and a second controller. The voice receiving module, located on the range hood, receives user voice commands and generates control commands. The first controller transmits stove control signals through the first and second wireless communication modules, enabling the second controller to control the stove's start-up, heat level, and shutdown. Furthermore, the first controller synchronously controls the range hood's start-up, speed, and shutdown based on control commands or stove status signals. This allows users to establish a synchronized control between the stove and range hood via voice commands without frequent manual operation.

Claims

1. A voice-activated control system for a range hood and a stove, comprising: A range hood includes a fan and a fan control unit; a voice receiving module is installed on the range hood to receive a voice command and generate a control command; a first controller is installed on the range hood and electrically connected to the voice receiving module and the fan control unit; a first wireless communication module is installed on the range hood and electrically connected to the first controller; a stove includes a stove body, a heating unit, and a firepower adjustment unit; a second wireless communication module is installed on the stove body and wirelessly communicates with the first wireless communication module; and a second controller is installed on the stove body and electrically connected to the second wireless communication module and the firepower adjustment unit. The first controller transmits a stove control signal to the second wireless communication module through the first wireless communication module according to the control command, so that the second controller controls the starting, fire intensity and shut-off of the heating unit, and the first controller controls the fan control unit to adjust the starting, speed and shut-off of the fan according to the control command.

2. The voice-linked control system for the range hood and stove as described in claim 1, wherein the voice receiving module includes at least one microphone, a voice recognition unit and an instruction conversion unit, wherein the microphone is used to receive the voice instruction, the voice recognition unit is used to recognize the voice instruction, and the instruction conversion unit is used to convert the voice instruction into the control command.

3. The voice linkage control system for the range hood and stove as described in claim 2, wherein the voice receiving module further includes a noise suppression unit and a wake-up unit. The noise suppression unit is used to reduce the interference of the range hood's operating noise or cooking noise on voice recognition, and the wake-up unit is used to start the voice recognition program after receiving a predetermined wake-up word.

4. The voice-activated control system for the range hood and stove as described in claim 1, wherein the first wireless communication module and the second wireless communication module are one or a combination of Bluetooth, Wi-Fi, ZigBee, Thread, Matter or radio frequency (RF) communication modules.

5. The voice-activated control system for the range hood and stove as described in claim 1, wherein the first wireless communication module has a built-in or connected first antenna, and the second wireless communication module has a built-in or connected second antenna.

6. The voice-activated control system for the range hood and stove as described in claim 1 further includes a status sensing unit installed on the stove and electrically connected to the second controller. The second controller can generate a stove status signal from the status information of the status sensing unit and transmit it back to the range hood via the second wireless communication module.

7. The voice-activated control system for the range hood and stove as described in claim 1, wherein the stove is an electronically controlled gas stove or an IH stove.
