Range hood comprising a casing

摘要

A case and a range hood provided with the case are described. The range hood includes a case and a volute (2). An air outlet (3) is disposed on an upper wall of the case. The volute (2) is mounted in the case, and includes a front baffle (4), a rear baffle, and an enclosing board (5). The front baffle (4) and the rear baffle are oppositely disposed on two sides of the enclosing board (5). An air inlet (3) is disposed on the front baffle (4). A recessed portion (7) is disposed on at least one side wall (6) of the case opposite to the enclosing board (5), and the recessed portion (7) is recessed away from the enclosing board (5). The recessed portion (7) is used for accommodating a corresponding protruding portion of the volute (2), and the protruding portion of the volute (2) refers to a portion of the volute (2) that protrudes from a plane where a region of the side wall (6) other than the recessed portion (7) is located. In this way, since the recessed portion (7) is disposed, it is possible to enlarge a fan system without significantly increasing the volume of the case.
