Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from stove combustion and the fumes harmful to the human body generated during the cooking process and discharge them outdoors. At the same time, it condenses and collects the fumes to reduce pollution, purify the air, and has anti-toxic and explosion-proof safety features.

[0003] The prior art installs the volute assembly in the casing, such as a Chinese patent disclosed in the name of a lift-up range hood frame structure and an easy-to-clean range hood (CN116878046A). This causes a large distance between the volute assembly and the air inlet screen, resulting in a poor smoking effect.

[0004] If the volute assembly can be arranged inside the smoke hood, the distance between the volute assembly and the air inlet screen can be shortened, so that the smoke extraction effect is good. Specifically, refer to the utility model patent of a range hood noise reduction structure (authorization announcement number: CN214661108U) disclosed in the Chinese patent publication. However, when the volute assembly is arranged inside the smoke hood, the size of the smoke hood becomes larger and it is not easy to carry as a whole. Utility Model Content
