Meanwhile, the gas indication means also plays a decoration role.

Description

【Technical field】 [0001] The invention relates to the field of household appliances, in particular to a range hood and a control method thereof. 【Background technique】 [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, which cannot be prominently displayed, users are likely to ignore these important information, resulting in serious consequences. In addition, some display interfaces are not easily integrated into the overall appearance design of the range hood, which ...

[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
