Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction grill mounting device for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, many devices are used in a mounting device for an intake grill of an air conditioner of this type.

An example of the above-mentioned conventional suction grill mounting device will be described below with reference to the drawings.

As shown in FIGS. 5, 6 and 7, the conventional suction grill mounting device has a resin piece 1 having a trapezoidal protrusion 1a.
And a resin piece 2 having two pairs of protrusions 2a, a boss 1b of the resin piece 1, a hole 2b of the resin piece 2, a washer 4,
Tighten with the screw 3 through 5, and the resin piece 1 to the front frame side,
When the resin piece 2 is fixed to the intake grill side with screws 6, and the intake grill is rotated to a certain angle with the boss 1b as a rotation axis, the protrusion 1a is fitted between the two pairs of protrusions 2a, and the intake grill is kept at the certain angle. It is a configuration to hold.

[0005]

However, in the above-mentioned structure, the number of constituent parts is large, the number of assembling steps is large, and the manufacturing cost is increased. In addition, since the resin pieces are fastened with screws, the torque and the holding force when the suction grill rotates are very likely to vary, and the screws are easily loosened. It required a great deal of damage to the assembly workability.

In view of the above problems, the present invention provides a suction grill mounting device in which the number of parts of the suction grill mounting device is reduced and the mounting property to the front frame is further improved.

[0007]

In order to solve the above problems, the suction grill mounting device of the present invention is formed integrally with the suction grill by using one side of the two resin pieces and the rotating shaft as a support portion of the suction grill. Then, the rotation shaft is inserted into a bearing provided on the front frame to form a center of rotation, and the other resin piece is fitted to a mounting portion provided on the front frame. This is a device capable of holding the suction grill at a constant angle by fitting a convex portion provided on one resin piece.

[0008]

According to the present invention, the number of parts is reduced and the assembling workability is remarkably improved by the above structure.
Further, the screwing of the parts constituting the rotary shaft is eliminated, and the holding force is formed by fitting the resin piece and the supporting portion of the suction grill, so that a very stable holding force can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An intake grill mounting device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view when the suction grill of one embodiment is held at a constant angle, and FIG. 2 is a perspective view seen from the back side. 3 is a partially enlarged view of FIG. 1, and FIG. 4 is a view of FIG. 3 seen from below. Reference numeral 7 is a suction grill, 8 is a front frame, and the suction grill 7 includes a support portion 7a for supporting the suction grill, and
The rotary shaft 7b of the intake grill 7 is integrally formed, and the support portion 7a is passed through the through hole 8d from the front side of the front frame 8 to form the rotary shaft 7b.
By inserting b into the bearing 8c provided on the front frame 8, the suction grill 7 can be rotated about the rotation shaft 7b. Reference numeral 9 denotes a resin piece, which is inserted and attached to a rib 8a for holding the resin piece 9 provided on the front frame 8. Reference numeral 8b is a rib for preventing the resin piece 9 from coming off, and has a spring property, and after the resin piece 9 is slid along the rib 8a and is bent, the stopper portion 9b of the resin piece 9 is fixed. The suction grill 7 can be attached to the front frame 8 with the resin piece 9 with one touch.

When the suction grill 7 is opened to a certain angle, the protrusion 9a of the resin piece 9 fits into the recess 7c provided in the support portion 7a of the suction grill 7 so that the suction grill 7 is held at that position. Has become.

When an attempt is made to open the intake grill 7 at a certain angle or more, the rotary shaft portion 7b bends and the bearing portion 8 of the front frame 8 is bent.
Although it may come off from c, by extending the resin piece 9 to the vicinity of the rotating shaft portion 7b, it is possible to prevent the portion of the rotating shaft portion 7b from being bent, so that it can be prevented from coming off.

When the suction grill 7 is held at a certain angle, the surface 7d of the concave portion 7c of the suction grill 7 and the surface of the convex portion 9a of the resin piece 9 are in contact with each other, but the suction grill 7 is rotated. Then, when the resin piece 9 is gradually closed in the direction of the arrow and the surface of 9a deviates from the surface of 7d, the holding force is lost and the intake grill 7 is closed. At this time 9a
It is possible to smoothly release the suction grill 7 from the state in which the suction grill 7 is held at a constant angle by inclining one or both of the surfaces 7d and 7d.

Further, by providing the slit 9e around the projection 9a of the resin piece 9, the projection 9a can be cantilevered and the suction grill 7 can be released from the held state more smoothly. In addition, the holding force of the suction grill 7 can be easily adjusted by changing the length of the slit 9e.

When the suction grill 7 is repeatedly opened and closed, the suction grill 7 and the resin piece 9 may rub each other, but in the present embodiment, the material of the suction grill 7 and the resin piece 9 is changed. This is prevented by using different materials.

Furthermore, at the moment when the protruding portion 9a of the resin piece 9 fits into the concave portion 7c of the suction grill 7, the elastic force of the resin piece 9 causes the resin piece 9 to hit the support portion 7a of the suction grill 7 and generate an impact sound. To do. For this reason, a small protrusion 9d is provided so as to prevent the resin piece 9 and the suction grill 7 from coming into contact with each other.

In the present embodiment, a concave portion is provided on the intake grill 7 side and a convex portion is provided on the resin piece 9 side, but the same effect can be obtained by providing a convex portion on the intake grill 7 side and a concave portion on the resin piece 9 side. Obtainable.

[0018]

As described above, according to the present invention, the support portion and the rotary shaft are integrally formed on the suction grill, and the resin piece is attached to the front frame with one-touch, thereby significantly reducing the number of parts. be able to.

Furthermore, by eliminating the screw tightening of the rotary shaft component, the tightening torque management becomes unnecessary,
It is possible to eliminate variations in the holding power of the suction grill.
