Abstract

The invention relates to the technical field of cooking fume treatment equipment, in particular to a pressure-equalizing air supply cavity which comprises an air flue and an air inlet part; the air flue comprises an annular hollow cavity defined by side walls and is provided with a plurality of air outlet parts in the circumferential direction; and the air inlet part is arranged on the outer side wall of the air flue and is configured to communicate with an air supply mechanism, wherein all cross sections of the hollow cavity are the same in size. Air flow flows along the annular hollow cavity and flows out from the multiple air outlet parts arranged in the circumferential direction, and pressure-equalizing air outlet is formed by the air flow at the air outlet parts. A smoke gathering cavity can receive the air flow with balanced pressure, then air outlet with stable pressure is formed, a smoke gathering air curtain is evenly distributed, and the smoke gathering effect is improved. The invention further discloses a range hood.

Description

technical field [0001] The present application relates to the technical field of oil fume treatment equipment, for example, it relates to a pressure equalizing air supply chamber and a range hood. Background technique [0002] With the increase of the height of high-rise buildings, the current kitchen range hoods have increased flue resistance and high-altitude wind resistance, often manifested as insufficient air volume and wind pressure, resulting in problems such as poor suction and escape of smoke. Some range hoods are equipped with a smoke collection chamber outside the smoke collection chamber. By supplying air to the smoke collection chamber, the air outlet of the smoke collection chamber forms a smoke collection air curtain on the periphery of the smoke collection chamber, so as to The smoke inlet forms a negative pressure zone to achieve effective smoking. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are ...
