Range hood and control method thereof

Abstract

The invention discloses a range hood, which comprises a smoke collecting hood and an anti-collision device, and is characterized in that the anti-collision device comprises a position sensor, a safety air bag and can send the current position relative to the smoke collecting hood to the position sensor in real time An induction headgear, the position sensor is arranged on the side of the smoke hood; the safety airbag is arranged adjacent to the position sensor, and the induction headgear is used to be worn on the user's body or head. Also disclosed is a control method for the above range hood. Compared with the prior art, the present invention has the advantages of: through the cooperation of the auxiliary inductive headgear and the position sensor on the range hood, the inductive headgear and the position sensor can be used to obtain the user's position and speed parameters in real time, and when the trigger conditions are met, Actively open the safety airbag to achieve active safety protection, which greatly improves the user's sense of security and realizes real-time and precise protection.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a range hood and a control method for the range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types. Top-suction range hoods use the principle of rising hot air to absorb and exhaust the naturally rising oil fumes generated during cooking. It has more and more widespread applications. [0003] A commonly used top-suction range hood includes a fume collecting hood and a casing arranged above the fume collecting hood, and a fan system is arranged in the casing. In order to maximize the suction of oil fume by the range hood, the distance between the lower edge of the fume collecting hood and the gas stove has a specified size. Especially the T-shaped flat-panel range hood has obvious edges and corners, and the lower end of the installed ran...

This structure is a way of passive avoidance. When the human body collides with the front of the moving housing, the housing moves backwards. In essence, the human body will still touch the front of the smoke collecting hood, but only by the buffering and buffering of the spring. The cushion reduces the pain of the human body; and if the human body touches the side of the corner of the smoke hood, the shell will not move backwards, and there will be a risk of bruising; in addition, this design will seriously affect the overall shape
