Description

Diffuser for indoor ventilation applicable to cover mounting and dismounting structure using magnet Technical Field The present invention discloses a diffuser for indoor ventilation, and more particularly, to a diffuser for indoor ventilation to which a cover attaching/detaching structure using a magnet is applied. Background Various buildings such as houses, schools, offices, and hospitals are often provided with ventilation systems that keep indoor air fresh. The ventilation system is provided with a diffuser for indoor ventilation for supplying outdoor air into a room. The indoor ventilation diffuser generally includes a diffuser body mounted to a ceiling and a diffuser cover coupled thereto, the diffuser body and the diffuser cover being coupled by screw fastening. Specifically, the diffuser cover is provided with screw portions and the diffuser body is provided with screw fastening portions providing female screw holes. According to the conventional structure, the screw portion is fastened to the screw fastening portion by rotating the diffuser cover after the screw portion is butted to the screw fastening portion and aligned, thereby coupling the diffuser cover to the diffuser body. When the diffuser cover is detached from the diffuser body, the diffuser cover may be rotated in the opposite direction. This screw fastening method has an advantage of firm coupling between the body and the cover, but is inconvenient and less rapid in the operation of coupling or removing the diffuser cover to or from the diffuser body. In particular, the cover is required to be assembled and disassembled in many turns, and particularly, the screw portion is required to be first butted to the screw fastening portion and aligned at the time of coupling, which causes inconvenience in operation and decreases rapidity. Moreover, the diffuser cover has a size larger than that of an adult's palm and needs to be rotated after being grasped by both hands, and the work is performed at the ceiling height, so that an operator may take a safety accident by carelessly dropping during the use of both hands. Disclosure of Invention First, the technical problem to be solved The present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a diffuser for indoor ventilation, which can improve convenience and rapidity of a diffuser cover mounting and dismounting operation and reduce the risk of occurrence of safety accidents.
