DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A service lid structure of an air conditioner according to the present invention will be described below in detail with reference to an embodiment shown in the drawings.

FIG. 1A is a front view of a main part of a service lid structure of an air conditioner according to an embodiment of the present invention.
FIG. 2B is a sectional view taken along line AA of FIG. In addition,
The indoor unit using the service lid structure of the air conditioner has the same configuration as the indoor unit shown in FIG. 2 except for the service opening and the service lid.

In the service cover structure of the air conditioner, as shown in FIG. 1 (a), engagement portions 3, 3 extending upward from the back surface side of the service cover 2 are provided at predetermined intervals. Provide. The service lid 2 has a handle 4 provided near one lower corner and a circular recess 5 provided near the other lower corner. As shown in FIG. 1B, a cylindrical projection 6 having a tool insertion hole 6 b extending rearward and having an opening at the bottom 5 a side of the recess 5 is provided on the bottom 5 a of the recess 5 of the service lid 2. Is provided. A bottom 6c is provided at the tip of the projection 6, and an engaging claw 6a is provided below the tip of the projection 6. With the service cover 2 attached to the service opening 20, the service cover 2 is inserted from below the service opening 20 so as to be sandwiched between the concave portion 5 of the service cover 2 and the engaging claw 6 a.
And a lower edge portion 1a extending upward while bending along the back side of the concave portion 5 and the back side of the concave portion 5, and further extending from the base of the projection 6 in the horizontal direction to the engaging claw 6a. In addition, the service lid 2, the engaging portions 3, 3 and the protrusion 6 are
It is molded integrally with synthetic resin.

In the service lid structure for an air conditioner having the above configuration, the engaging portions 3, 3 are engaged with the upper edge of the service opening 20, and the engagement claws 6a are fitted to the lower edge 1a of the service opening 20. The lower edge 1a of the service opening 20 is engaged with the engagement claw 6a of the projection 6 and the recess 5 of the service lid 2.
, The service lid 2 is fixed to the service opening 20. On the other hand, a service unit (not shown) in the casing 1
At the time of maintenance, as shown in FIG. 1C, the driver 7 is inserted into the tool insertion hole 6b of the protrusion 6, and the protrusion 6 is elastically deformed by raising the tip of the driver 7 upward. Then, the engagement between the lower edge 1a of the service opening 20 and the engagement claw 6a is released. Then, pull the handle 4 (see FIG. 1A) of the service cover 2 toward the user to open the service opening 20.
Remove the service cover 2 from.

As described above, the service cover structure of the air conditioner does not require a screw for fixing the service cover 2 to the service opening 20. Moreover, when removing the service lid 2, instead of loosening the screw, the protrusion 6 is elastically deformed by the driver 7 to release the engagement between the lower edge 1a of the service opening 20 and the engagement claw 6a. The service lid 2 can be easily removed from the service opening 20. Therefore, maintenance work of the service section in the service opening 20 is facilitated, and workability can be improved.
