Problems solved by technology

[0002] At present, some cooker hoods on the market use small-sized TFT displays to display relevant information. However, due to the trend of smart home appliances and more and more functions, the area of ​​the TFT display interface of the range hood is relatively limited. To display various functions and status parameters on a small area, it is inevitable that the displayed characters and patterns cannot be too large. It is very inconvenient for users to check these characters and parameters while cooking.
Especially for some important parameters or alarms, they cannot be prominently displayed, and users are likely to ignore these important information, which will bring serious consequences
In addition, some display interfaces are not easy to be integrated into the overall appearance design of the range hood, which makes the appearance of the range hood uncoordinated
[0003] In addition, when the user chooses cooking methods such as boiling or stewing, he does not need to stay near the stove or the kitchen for a long time, but the existing range hoods do not have corresponding real-time monitoring and remote prompting functions, and it is difficult for users to leave time, it is easy to cause the water in the cooking container to evaporate, the food will be burnt, and even cause a fire
In order to avoid these situations, the user has to go to the stove to check the status of the cooking container every once in a while, which is very troublesome

Embodiment approach

[0026] As an embodiment of the present invention, the smoke detection device 10 includes an ultrasonic sensor, which is installed in the inner space of the main body of the range hood 1 . As the smoke concentration changes, the voltage signal output by the ultrasonic sensor also changes. By detecting the voltage signal, the current smoke concentration can be calculated. Therefore, the smoke concentration information detected by the smoke detection device 10 is a Voltage value. The smoke indicating device 20 includes light-emitting elements of more than two colors, and the light-emitting elements may be light-emitting diodes (LEDs), cold-cathode fluorescent lamps (CCFLs), organic light-emitting diodes (OLEDs), and the like. Since LED lamps have low power consumption, low cost, and multiple colors, LEDs are preferred as the light emitting elements of this embodiment. In a preferred embodiment of the present invention, the smoke indicating device 20 includes a red LED, a green L...

Abstract

Disclosed is a range hood (1) and a control method thereof. The range hood includes gas detection means (10) for detecting gas concentrations, and further includes: gas indication means (20) and control means, wherein the control means is used for controlling the gas indication means to display corresponding colors and / or brightness and / or images according to gas concentrations information detected by the gas detection means. Thus, users can know current gas concentrations by observing the colors and / or brightness and / or images displayed by the gas indication means, to prevent occurrence of fire accidents, and can infer the cooking state, to bring convenience to cooking of the users. Meanwhile, the gas indication means also plays a decoration role.
