Description

Technical Field

[0001] The utility model relates to the field of range hoods, in particular to a top-side double-suction range hood. Background Art

[0002] Range hoods are electrical appliances used in the kitchen. Their main function is to absorb and remove the fumes and odors generated during cooking. There are many types of range hoods, including Chinese, European, and side-suction types. Different types of range hoods may differ in appearance, suction power, and installation methods. Range hoods play an important role in modern kitchens, not only improving the comfort of kitchen operations, but also having a positive impact on the hygiene and air quality of the home environment.

[0003] Top-side double-extraction range hoods are usually installed on the top of the kitchen. They can be directly suspended above the ceiling or fixed to the wall through a mounting bracket. This design allows the oil smoke to be absorbed from above the cooking area, effectively reducing the spread of oil smoke in the kitchen space. Double-extraction range hoods have double-sided or multi-sided air intake design, which can absorb oil smoke and smoke from multiple directions at the same time. This design captures oil smoke more effectively than a single-sided air intake, improving the efficiency of oil smoke extraction.

[0004] Generally, multiple stoves are designed on household stoves. Although a single double-suction range hood covers the stove, its smoke extraction hole is fixed. When one of the stoves is in use, the smoke extraction efficiency of the smoke extraction hole on the other side will be low. Meanwhile, if the smoke extraction hole of the range hood cannot completely correspond to the position of each stove, the smoke will be concentrated and diffused in the kitchen, resulting in poor smoke emission, affecting the air quality and user comfort of the kitchen. Therefore, a top-side double-suction range hood is proposed to solve the above problems. Utility Model Content

[0005] In order to remedy the above deficiencies, the utility model provides a top-side double-suction range hood, aiming to improve the problem in the prior art that the smoke intake holes of double-suction range hoods are fixed, which will lead to low efficiency of the smoke intake holes on the other side when the stove on one side is in use.
