FIG. 2 is a perspective view of a main part of the indoor unit of the air conditioner according to the first embodiment of the present invention. In the figure, the upper suction grill 7 is indicated by the upper suction port 3b of the front panel 5.
Mounted on the upper surface of the. The front air filter 14, which is detachably installed along the insides of the front suction grill 6 and the top suction grill 7 while curving the groove prepared in the front panel 5 as a guide, is the innermost portion of the top suction port 3b. It is possible to cover the front suction port 3a and the top suction port 3b with one sheet. However, as shown in FIG. 2, the indoor unit width may be divided into two.

FIG. 3 is an enlarged sectional view of a portion where the front end of the upper suction grill 7 is mounted on the front panel 5. A projecting portion 7b projecting over the entire width of the grill is prepared at the tip of the upper surface suction grill 7, and a receiving portion 5b into which the projecting portion 7b can be inserted is prepared at the mounting portion of the front grill 5. The upper surface suction grill 7 is positioned by inserting the protruding portion 7b into the receiving portion 5b. A cushion material may be inserted between the protruding portion 7b and the receiving portion 5b in order to suppress chattering noise during operation of the air conditioner. This cushion material may be attached to either the protruding portion 7b side or the receiving portion 5b side.

FIG. 4 is an enlarged sectional view showing a portion where the rear end portion of the upper surface suction grill 7 is fixed to the front panel 5. The upper suction panel 7 covers the front panel 5, and the fixing holes 5c formed in the front panel 5 and the fixing holes 7c formed in the upper suction grill 7 are aligned with each other, so that the locking component 15 is formed. The upper surface suction grill 7 is fixed by penetrating the above two holes.

A method of fixing the locking component 15 will be described with reference to the plan sectional view of FIG. 5 and the perspective view of FIG. As shown in FIG. 5, the locking component 15 is composed of a locking portion 15a and an operating portion 15b. The locking portion 15a is a portion to be inserted into the fixing hole 5c formed in the front panel 5 and the fixing hole 7c formed in the upper surface suction grill 7, and corresponds to the thickness of the fixing hole portions 5c, 7c. In addition to the depth, it has a locking key portion, and according to the shape shown in FIG. 5, the front panel 5 and the upper grill 7 can be sandwiched and fixed by sliding to the right after insertion.

It should be noted that the operating portion 15b of the locking component 15 may have an arrow shape as shown in the figure, and such a shape is intended to make the operation direction easy for the operator to understand. In addition, the locking component 1
5 may have a color tone different from that of other surrounding parts so that the operator can easily confirm the existence of the parts. Further, as shown in FIG. 6, the fixing hole 5c formed in the front panel 5 may have a convex shape so that the fixing hook-shaped portion of the locking portion 14a of the locking component 14 can be easily inserted. Good.

FIG. 7 is a cross-sectional view of the indoor unit, showing a state in which the front suction grill 6 is flipped up. As shown in FIG. 2, the front suction grill 6 has hinges on both sides and is attached to the front panel, and can be flipped up as shown. The locking component 15 is in a position where it can be operated in this state, and does not appear in the appearance in the normal use state as shown in FIG. 1 and does not damage the design of the indoor unit.

Since the air conditioner according to the first embodiment of the present invention is configured as described above, the work of removing the top suction grill can be performed only by the work from the front side close to the worker, and thus the work can be further performed. It can be done easily and safely.

Further, since the air filter can cover the front suction port and the top suction port without being divided into two parts in front and rear, it can be easily removed only by the work from the front side, and the labor of cleaning can be reduced. You can

Second Embodiment of the Invention The second embodiment of the present invention will be described below with reference to the drawings. FIG. 8 shows the front panel 5.
FIG. 6 is a plan view showing how the upper surface suction grille 7 is attached to the main body 1 including the above. The shape of the upper surface suction grill 7 is such that the lateral width of the front end on the inner side of the front panel is narrower than the lateral width of the rear end. On the other hand, front panel 5
The upper-side suction grill mounting portion on the side is also shaped to match this, and the positioning of the upper-side suction grill 7 is easy by simply inserting the protruding portion 7b provided at the tip of the upper-side suction grill into the receiving portion 5b of the front panel 5. Therefore, workability at the time of attachment / detachment work, which is a high place work, is improved.

Third Embodiment of the Invention Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. FIG. 9 is an enlarged cross-sectional view showing a portion where the rear end portion of the upper surface suction grill 7 is fixed to the front panel 5. The upper suction panel 7 covers the front panel 5, and at least one protrusion 7d is provided on the upper suction grill 7 side so as to enter the opening of the upper suction port 3b of the front panel 5. As a result, when the upper surface suction grill 7 is mounted, the upper surface suction grill 7 does not slide down toward the front even if the locking component 15 is not inserted, and the workability when inserting and removing the locking component 15 can be improved. Further, the same effect can be obtained by providing the above-mentioned protrusion on the front panel 5 side and inserting it into the opening formed in the upper surface suction grill 7.

[0024]

As described above, in the indoor unit of the air conditioner according to the present invention, a hole is provided at the rear end of the upper suction grill by providing a projecting portion at the front end and fitting it into the front panel receiving portion. Since the parts are used to fix the front panel with the locking parts, the detaching work can be performed only on the front side close to the operator, and thus the work can be performed more easily and safely.

Further, since the locking parts are in the shape of an arrow, the direction of the operation can be shown to the operator in an easy-to-understand manner, and the color tone is different from the other surrounding parts, so that the operator can check the locking parts. The existence can be confirmed easily.

Further, the shape of the top suction grill 7 is such that the width of the front end on the back side of the front panel is narrower than the width of the rear end, so that the top suction grill 7 can be easily positioned and placed at a high place. Workability at the time of attaching and detaching work, which is work, is improved.

Further, since the air filter can cover the entire suction surface without being divided into front and rear parts, it can be easily removed, which contributes to the reduction of manufacturing cost and the labor of cleaning. .
