Description

Technical Field

[0001] The present invention belongs to the technical field of range hoods, and particularly relates to a range hood that actively contacts users in case of abnormal environment. Background Art

[0002] As an important household appliance in the kitchen, the range hood is mainly used to absorb the oil fumes, odors and harmful gases released during the combustion process, such as carbon monoxide, carbon dioxide, etc., to keep the kitchen air fresh. However, although range hoods have been widely used and continuously optimized in terms of smoke extraction rate, noise control, energy efficiency, etc., there are still some safety hazards that cannot be ignored. Especially when used for a long time or unattended, it may cause fire or poisoning accidents due to factors such as gas leakage, dry burning, oil stain accumulation, etc.

[0003] Currently, the range hoods on the market mainly adopt the following technical means to improve the purification efficiency and use convenience:

[0004] Variable frequency control technology. Some range hoods are equipped with intelligent variable frequency motors, which can automatically adjust the wind speed according to the smoke concentration to improve the smoke extraction effect and reduce energy consumption at the same time.

[0005] High-efficiency filtration system. Modern range hoods mostly adopt multi-layer filter screens or centrifugal separation technology to improve the oil fume separation efficiency, reduce oil stain adhesion and extend the service life.

[0006] Touch and remote control functions. Some high-end range hoods already support touch operation and are connected to the mobile APP through the smart home system to realize functions such as remote switch, wind speed adjustment, etc.

[0007] However, these improvements still cannot completely solve the safety problems that users may encounter during use. There are mainly the following limitations:

[0008] Lack of comprehensive safety monitoring function. Traditional range hoods only focus on the smoke extraction and exhaust effect, but lack effective real-time monitoring of dangerous situations such as gas leakage, abnormal temperature, dry burning, etc., and cannot timely remind users or take corresponding safety measures.

[0009] The notification mechanism is lagging or imperfect. Existing range hoods usually use buzzers or indicator lights for local alarm. This method may not be able to receive the alarm in time when the user is far away from the kitchen, increasing the risk of accidents.

[0010] The level of intelligence is limited. Although some range hoods support remote control, their degree of automation is low and still rely on users to manually adjust the wind speed or switch on and off. They fail to realize intelligent decision-making based on environmental monitoring data, so they may not be able to effectively respond to emergencies in some cases.
