DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a suction grill which is attached to and detached from, for example, a front surface of an air purifier.

[0002]

2. Description of the Related Art In recent years, wall-mounted air purifiers and the like have been widely used. In such an air purifier,
A suction grille is provided to suck indoor air.
Generally, a pre-filter and a dust collecting part are arranged behind the suction grille, and maintenance such as cleaning and element replacement is required for each of them at predetermined intervals. For this reason, the suction grill is detachable. Further, in order to facilitate maintenance, a structure for easily attaching and detaching the suction grill is adopted.

[0003]

Incidentally, an air purifier or the like is sometimes arranged above a wall surface. In such a case, if a structure is adopted in which the suction grille can be attached and detached with a single touch, etc., it is good that the suction grille can be easily attached and detached. In particular, in a maintenance work at a high place where the hand can barely reach the suction grille, it is not easy to work while taking care not to drop the suction grille.

[0004] In a system in which the upper portion of the suction grille is removed first and then the lower portion of the suction grille is removed, there is a risk that the suction grille may fall during work at a high place. The present invention has been made in view of the above problems, and an object of the present invention is to provide a suction grill mounting structure in which a suction grill is not unnecessarily dropped during maintenance, and is easily detachable.

[0005]

Means for Solving the Problems As means for solving the problems to achieve the above object, the aspect of the invention described in claim 1 is as follows.
In a suction grille mounting structure in which a suction grill is detachably mounted on a storage recess provided on a front surface of a main body of the air conditioner, a hook formed on an upper portion of the suction grill, and provided on an upper portion of the storage recess, A hook engaging portion where the hook is hooked and engaged, and an engagement which holds the hook engaged only in an angular range from a straight posture in which the suction grille is accommodated in the accommodation concave portion to a predetermined inclination angle. And a holding means.

In this embodiment, when the user removes the suction grille from the accommodation recess, the user pulls out the lower part of the suction grille forward, and then lifts the lower part upward to rotate the suction grille about the upper part. . Only when the suction grill is inclined to a predetermined inclination angle, the hook on the upper part of the suction grill is released and the suction grill can be removed. That is, since the suction grill cannot be removed by slightly pulling out the lower portion of the suction grill, the suction grill is not unnecessarily dropped. In particular, when the air conditioner is arranged at a high place such as an upper part of a wall or a ceiling surface, the suction grill does not fall unnecessarily, and the workability of maintenance is good.

According to a second aspect of the present invention, in the first aspect, the engagement holding means is provided opposite to the projection formed on the back surface of the hook and the hooking engagement portion above the accommodation recess. And an engagement portion that engages with the projection only in the above-mentioned angle range. In this aspect, the hook engagement state is maintained by the projection on the hook rear surface engaging with the engagement portion. The above-mentioned predetermined inclination angle can be easily adjusted only by changing the shape, the size, and the like of the projection or the engaging portion.

According to a third aspect of the present invention, in the first or second aspect, the holding member is displaceable between a first state in which the lower portion of the suction grill is held in the housing recess and a second state in which the holding is released. The apparatus further includes a member and an operating member for switching the holding member between the first and second states with one touch. In this aspect, the lower portion of the suction grille can be very easily attached and detached with one touch by operating the operation member. Even if the lower part of the suction grill is removed by such a one-touch operation, the mounting state of the upper part of the suction grill is ensured, so that the suction grill does not unnecessarily fall off. That is, unnecessary detachment is prevented despite the fact that it is easily detachable as a whole.
