[0018] Please see Figure 1The diagram shows a simplified structural diagram of an exemplary gas detection system according to this application. The gas detection system includes a gas stove 1, a range hood 2, a gas detection device 3, and a window opening detection device 4. The gas stove 1 includes a first controller 11; the range hood 2 includes a second controller 21, N drive modules 22, and a fan device 23; where N is an integer greater than or equal to 2; the second controller 21 is connected to each of the N drive modules 22; the N drive modules 22 are connected to each of the fan devices 23; the gas detection device 3 is communicatively connected to the first controller 11; the window opening detection device 4 is communicatively connected to the second controller 21; and the first controller 11 is communicatively connected to the second controller 21.

[0019] For example, it may include two drive modules: a first drive module that controls the fan device to achieve low-speed exhaust, and a second drive module that controls the fan device to achieve high-speed exhaust. Of course, as needed, it may also include other drive modules with different wind speeds, such as a third drive module, a fourth drive module, etc.

[0020] In one exemplary embodiment, the gas stove 1 includes a first communication module; the range hood 2 includes a second communication module; the first and second communication modules are wireless communication modules. The first communication module is used to receive external signals and send them to the first controller 11, such as receiving the detection signal from the gas detection device 3; the second communication module is also used to send the received external signals to the second controller 21, such as receiving the detection signal from the window opening detection device 4, and the subsequent detection signal from the door opening detection device.

[0021] Of course, the controller can also send its output warning information or control signals to the receiving end based on the communication module. For example, it can send gas leak information to the terminal so that users can be informed of the safety status of their home in a timely manner. The controller can also control the opening and closing devices of corresponding appliances. For example, the first controller 11 can control the opening and closing of the gas valve of the gas stove 1, and the second controller 21 can control the opening and closing of the range hood 2.

[0022] The window opening detection device 4 can detect the opening and closing status of the window, and the gas detection device 3 can detect gas leaks. When the gas detection device 3 detects a gas leak, the first controller 11 can send a first detection signal to the second controller 21. The second controller 21 will receive the detection signal from the window opening detection device 4. When the window is detected to be open, the second controller 21 can choose not to turn on the fan device 23, or it can turn on the connection circuit of the drive module 22 corresponding to low wind speed (such as the first drive module), so that the fan device 23 can achieve low wind speed exhaust. When the window is detected to be closed, the second controller 21 can turn on the connection circuit of the drive module 22 corresponding to high wind speed (such as the second drive module), so that the fan device 23 can achieve high wind speed exhaust. In this way, the range hood 2 does not need to maintain high-speed exhaust at all times, reducing resource consumption.

[0023] In one exemplary embodiment, the range hood 2 further includes N switches; each of the N switches corresponds one-to-one with one of the N drive modules 22; the second controller 21 is connected to one drive module 22 via one switch. Thus, different wind speeds can be generated by controlling the opening and closing of different drive modules 22. Specifically, the drive device can be a fan, and different drive modules 22 can drive different wind speeds of the fan device 23; in other embodiments, the drive device can specifically include multiple fans, with each drive module 22 connected to one fan, so the more drive modules 22 are activated, the stronger the wind power generated by the range hood 2.

[0024] For example, the range hood 2 may include N fan drive circuits. Specifically, each fan drive circuit includes a second controller 21, a switch, a drive module 22, and a fan device 23 connected in sequence. Different fan drive circuits can achieve different wind speeds for the fan device 23. Each fan drive circuit may also consist of a second controller 21, a switch, a drive module 22, and a fan connected in sequence, thereby achieving different wind speeds for the fan device 23 by activating different numbers of drive circuits.

[0025] It should be noted that the content protected by this application includes the connection method, structural composition, and installation location of each device and component. Based on this system structure and layout design, the spread of gas leakage in each area can be obtained more comprehensively. The working status of multiple drive modules 22 of the range hood 2 can be controlled through the window detection device 4, thereby reducing resource consumption. The detection logic of the gas detection device 3 and the window detection device 4 are both existing technologies.

[0026] In one exemplary embodiment, the gas detection system further includes a door opening detection device connected to the second controller 21. When the door opening detection device detects that the kitchen door is open, the second controller 21, based on the detection signal, may either not turn on the fan device 23, or control the lower-speed drive module 22 to turn on, thereby achieving low-speed exhaust by the fan; conversely, it may turn on the fan device 23 or enable higher-speed exhaust by the fan. The door opening detection device can specifically be a distance sensor, photoelectric switch, or Hall sensor, etc., which can detect the opening and closing status of the door; these are all existing technologies and will not be described in detail here. In one exemplary embodiment, the window opening detection device 4 is mounted on a hinged window; the window opening detection device 4 includes a distance sensor or a Hall sensor. When the window opening detection device 4 is a distance sensor, it can be mounted on the window frame to detect the distance from the window to the window frame, thereby determining whether the window is open. When the window opening detection device 4 is a Hall sensor, a linear Hall sensor can be used in conjunction with a magnet, such as mounting a magnet on the hinge and a Hall sensor on the window. When the window rotates, the relative position of the Hall sensor and the magnet changes, causing a change in magnetic field strength, thereby generating a voltage signal corresponding to the angle, realizing the detection of the window's open / closed state. In other embodiments, it can also be a switch-type Hall sensor, etc.

[0027] In one exemplary embodiment, the window opening detection device 4 is located at the switch of the sliding window; the window opening detection device 4 includes a micro switch, which generates different voltage signals when pressed and unpressed, thereby enabling the detection of whether the sliding window is open. The window opening detection device 4 and the corresponding detection logic described above are all prior art.

[0028] In one exemplary embodiment, the gas detection system further includes a third controller; the gas detection device 3 is connected to the first controller 11 and the second controller 21 respectively via the third controller; the window opening detection device 4 is connected to the first controller 11 and the second controller 21 respectively via the third controller. The third controller can be a device mounted on other devices, such as a central control device in a smart home system, enabling whole-house smart connectivity. Alternatively, it can be mounted on a mobile phone, tablet, or other electrical appliance; no limitation is made here. The use of a third controller further increases the application flexibility of the gas detection system and reduces the resource consumption of the controllers of the gas stove 1 and range hood 2, avoiding interference with the normal operation of these electrical appliances.

[0029] In one exemplary embodiment, the window opening detection device 4 includes M first detection devices; where M is an integer greater than or equal to 2; each first detection device is installed on a window in a different area of ​​the house. Specifically, first detection devices can be installed on the windows of the kitchen and living room respectively to monitor the opening and closing status of the windows in the kitchen and living room. When an alert is needed, information including the window opening and closing status can be generated and sent synchronously to the user terminal. Furthermore, by installing first detection devices in different areas of the house, a more comprehensive understanding of the window opening and closing status can be obtained, thereby controlling the operation of different drive circuits of the range hood 2 and further reducing the power consumption of the range hood 2 (e.g., if the kitchen window / kitchen door and living room window are open, the range hood 2 can be turned off). In one exemplary embodiment, the gas detection device 3 includes K second detection devices; where K is an integer greater than or equal to 2; each second detection device is located in a different area of ​​the kitchen. The second detection devices can be placed in different areas of the kitchen to ensure the reliability of gas detection and accurately locate the gas-generating area, allowing for subsequent investigation of the cause.

[0030] In another aspect, this application also discloses an intelligent kitchen appliance system, which includes the aforementioned gas detection system, wherein the gas stove 1 and the range hood 2 are both intelligent gas stove 1 and intelligent range hood 2.

[0031] Both the aforementioned smart gas stove 1 and smart range hood 2 are equipped with a smart voice control module. The smart voice control module includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the gas stove 1 and range hood 2 to perform corresponding operations, thereby realizing intelligent control of the gas stove 1 and range hood 2 and improving the user's experience of using smart appliances.

[0032] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
