Description

Technical Field

[0001] The present application relates to the technical field of range hoods, and more specifically, to a multifunctional range hood. Background Art

[0002] Kitchens are usually equipped with range hoods, which have built-in exhaust structures that can quickly extract stove combustion waste and cooking fumes that are harmful to the human body and discharge them outdoors, reducing pollution, purifying the air, and providing anti-toxic and explosion-proof safety features.

[0003] To address the issues of significantly increasing range hood noise due to increased fan speed and causing users to hit their heads while cooking due to shortening the distance between the range hood and the stove, patent publication number CN211424500U proposes a range hood that delivers air into the air chamber through an air inlet. This technical solution significantly improves the range hood's suction efficiency and reduces the likelihood of oil smoke escaping into the open kitchen space.

[0004] Although the above-mentioned existing technical solution can greatly improve the suction efficiency of the range hood and reduce the probability of oil smoke leaking into the open space of the kitchen by transporting air flow into the air cavity through the air inlet, it still has the following defects: during use, since the range hood discharges oil smoke through the exhaust fan for a long time, oil stains will adhere to the exhaust fan and it is inconvenient to clean. At the same time, during use, the oil stains on the range hood will drip onto the stove surface, reducing the use effect of the range hood.

[0005] In view of this, we propose a multifunctional range hood. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this application is to provide a multifunctional range hood, which solves the technical problem that oil stains adhere to the exhaust fan and are inconvenient to clean, and the oil stains on the range hood drip onto the stove surface during use, reducing the use effect of the range hood. It realizes the technical effect of self-cleaning of the range hood and collecting oil stains.

[0008] 2. Technical solution
