Benefits of technology

The invention provides a range hood with low noise and high fume-exhausting performance. The hood optimizes airflow to achieve smooth exhaustion of fumes and reduces noise. It includes a blower fan and baffle to prevent fumes from diffusing outside the hood and improve efficiency.

Problems solved by technology

In light of general cooking habits, frying food by way of raging fire and hot oil makes loud noise; meanwhile, it also produces an unpleasant smell of fumes.
Nonetheless, when exceeding 55 dB, the noise interferes with regular conversations, and is prone to discomfort people.
Even though most range hoods are equipped with a multi-section adjustable system so that users can turn down air flow according to usage requirements in an attempt to keep noise made by a range hood less than 55 dB, fan's air flow and static pressure will simultaneously lower dramatically resulting in incapability of exhausting fumes thoroughly.

Abstract

A range hood includes a housing, a cover, an exhaust pipe and at least two vacuum fans. The housing has a top and bottom openings opposite to each other. The cover is disposed in the housing and adjacent to the bottom opening. The cover has an air inlet facing the bottom opening. The exhaust pipe is disposed in the housing and located between the top opening and the cover. The exhaust pipe has an air outlet adjacent to the top opening and communicates with the cover. The vacuum fans are disposed in the cover and located between the air inlet and the exhaust pipe. Each vacuum fan has an air flow inlet adjacent to the air inlet and an air flow outlet adjacent to the air outlet. An area of the air inlet is greater than or equal to an area of the air flow inlets.

CROSS-REFERENCE TO RELATED APPLICATION[0001]THIS APPLICATION CLAIMS THE PRIORITY BENEFIT OF CHINA APPLICATION (CN201721416490.9 FILED ON 2017 Oct. 30). THE ENTIRETY OF THE ABOVE-MENTIONED PATENT APPLICATION IS HEREBY INCORPORATED BY REFERENCE HEREIN AND MADE A PART OF THIS SPECIFICATION.FIELD OF THE INVENTION[0002]The invention relates to a range hood, and more particularly to a low-noise range hood.BACKGROUND OF THE INVENTION[0003]As society develops and changes, the composition of the family has changed from a large-size family in the past to small-size family nowadays. Particularly in Asian countries with high population density, the spatial boundary between a living room and a kitchen / dining room in a house trends to become increasingly blurred. With the popularization of mobile devices such as smart phones, functions of a living room are gradually being replaced. Most family members used to spend time chatting in a living room, however, they now get used to doing so in a kitche...
