A part that is CO-burned, a filter that removes dust and odor, and a removable filter, a fan that takes in the outside air that connects the suction port and the filter and blows it, and
A main body having a fixing portion, and a fixing knob for covering the filter and fixing the fixing portion to a fixing portion of the main body at an end thereof, provided on the main body or the intake grille, wherein the front case and the intake grille constitute a top surface constituting the main body. A contact surface between the case and the front surface of the main body, and a contact surface between the upper surface of the front case and both ends of the intake grille is inclined downward toward the front surface of the main body.

When the intake grill is removed for maintenance or the like, the intake grill is shifted by its own weight along the inclined surface of the front case and can be easily removed simply by operating the fixing knob.

Each end face of the front case that contacts the lower end of the intake grille is formed so as to have a surface that is inclined upward toward the inside.

[0009] When the fixing knob is operated to remove the intake grill, the end surface does not enter the inside of the front case, but can be easily displaced downward along the inclined surface and removed.
