Document Type and Number:
WIPO Patent Application WO/2022/021767
Kind Code:
A1
Abstract:
An air guide box, comprising a box body (21), the box body (21) comprising a first side wall (214) and a second side wall (215) arranged opposite to each other. An air inlet (211) is provided on the first side wall (214). Air outlets (212) are respectively formed between the corresponding edges of the first side wall (214) and the second side wall (215). A position on the second side wall (215) corresponding to an air inlet (211) is a maximum concave position (P). A guide inclined surface (216) is formed on the inner side surface of the second side wall (215). Also provided is a recirculating range hood using said air guide box. By providing the guide inclined surface (216) on the top surface of the air guide box, an airflow can be easily guided to the air outlets (212), thereby avoiding a vortex generated from direct rebounding of an unguided airflow.
