Abstract
Description
Technical Field
[0001] This invention relates to the field of range hood technology, and more specifically, to a range hood control device and control method thereof. Background Technology
[0002] During kitchen use, a large amount of oily fumes are often generated, making the kitchen environment greasy and difficult to clean. These fumes also contain many harmful substances, and prolonged exposure to such environments can lead to various illnesses. Therefore, range hoods have been developed to remove most of the oily fumes produced during cooking, improving the kitchen environment and reducing the harm caused by these fumes to both the kitchen environment and human health.
[0003] However, in actual use, due to environmental factors such as atmospheric pressure and flue pressure, cooking fumes cannot be completely extracted into the range hood. Therefore, improving the fume extraction capacity of range hoods is a problem that needs to be solved.
[0004] To address the aforementioned issues, patent document CN202210461586.6 discloses a range hood and its control method, particularly relating to the field of range hood technology, for improving the extraction rate of cooking fumes. The range hood includes: a body; a fan assembly disposed within the body; a drive assembly disposed within the body for driving the fan assembly to move within the body; multiple fume sensors, including a first fume sensor and a second fume sensor, respectively disposed on opposite sides of the body; and a controller electrically connected to the fan assembly, drive assembly, and multiple fume sensors. The controller is configured to: acquire the real-time fume concentration value detected by a target fume sensor, which is either the first or second fume sensor; and when the fume concentration value is greater than a first preset value within a first preset time period, control the drive assembly to drive the fan assembly to move a first distance closer to the target fume sensor. The first and second oil fume sensors are limited to the sides of the machine body and cannot be changed according to the actual environment, resulting in poor detection effect. Furthermore, the fact that only the first and second oil fume sensors are set up cannot meet different environmental requirements and adjust the air quality of the environment. Summary of the Invention

[0016] The beneficial effects of this invention are: This structure incorporates a movable sensing device, detachable from the range hood and used for detecting environmental conditions, which can be placed anywhere on the range hood's surface, thereby expanding the detection range to include air conditions at different locations. Furthermore, the sensors employed in this structure include particulate matter sensors, temperature sensors, infrared temperature sensors, formaldehyde concentration sensors, humidity sensors, photosensors, and carbon dioxide sensors, enabling multiple detection methods and effectively improving air quality.

It can be placed anywhere on the surface of the range hood 1 or in the kitchen or hall, thereby expanding the detection of air conditions in different locations.
[0026] The electronic control board 102 described in this structure is connected to a voice controller 105. The voice controller 105 is a type of controller, specifically a language-driven controller in a human-machine system. Its main structure is a computer speech recognition system.

[0028] The sensor housing cover 201 of this structure is equipped with a charging port 204, which is connected to a rechargeable battery 212. The output terminal of the rechargeable battery 212 is connected to the sensor circuit board 202. The function of the charging port 204 is to allow the rechargeable battery 212 to be charged.

[0031] This invention discloses a control method for a range hood control device, characterized by the following control steps: Step 1: Start the range hood 1 and the motion sensor 2. After the range hood 1 and the motion sensor 2 are successfully connected via the communication module, wait for the range hood 1 to select its control mode. Step 2: Press the range hood control switch 101 on the range hood 1 to enter the automatic control mode or manual control mode; Step 3: In automatic control mode, select: cooking mode, kitchen mode, or ventilation mode. The operation option information of cooking mode, kitchen mode, and ventilation mode is input to the electronic control board 102 through the communication module.

[0032] Manual control mode: The range hood control switch 101 directly outputs start information to the control board 102, and the control board 102 directly starts the range hood fan 103 and / or the range hood lighting 104, while the motion sensor 2 is in a stopped state.
[0033] Specifically, in step 3, the humidity sensor 210 and the photosensor 211 on the sensor circuit board 202 are activated in the cooking mode to detect the surrounding environment of the range hood 1.
