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

[0002]

2. Description of the Related Art A vertical sectional view of a conventional wall-mounted air conditioner is shown in FIG. In FIG. 3, 1 is an air conditioner main body, 3 is a heat exchanger installed inside the main body 1 and extending vertically, 4 is a through-flow fan installed substantially horizontally below the wake side of the heat exchanger 3, 2 Is a front panel arranged on the upstream side of the heat exchanger 3, 10 is an outlet grille that limits the outlet 5, 6 is an outlet louver provided at the outlet 5, and 7 is the bottom of the heat exchanger 3. Is a drain pan that also serves as a stabilizer, 9 is a suction port formed in the front panel 2, 8 is an air filter disposed behind the suction port 9, and 14 is a base member.

A drain pan 7 which also functions as a stabilizer is adhered onto a blow-out grill 10 and a horizontal rule is attached to the blow-out grill 10.
Both ends of the rotary shaft of the bar 6 are rotatably supported. As shown in FIG. 2, at both ends of the blowout grill 10,
The inclined wall 16 is brought into contact with the wall 15 formed on the base member 14 and fastened by the screw 12. The flow-through fan 4 is supported by the main body 1, and the base member 14 is fixed to the main body 1.

During operation of the air conditioner, the fan 4 rotates,
Refrigerant from an outdoor unit (not shown) circulates through the heat exchanger 3. Then, the indoor air becomes
The air filter 8 is sucked into the main body 1 through the suction port 9.
After the dust contained therein is removed by flowing through the heat exchanger, the refrigerant is cooled or heated by exchanging heat with the refrigerant in the process of flowing through the heat exchanger 3. Next, it is urged by the once-through fan 4, and thereafter, the outlet
It is guided by the bag 6 and blown out into the room.

[0005]

In the above-mentioned conventional structure, the drain pan 7 also serving as a stabilizer has an outlet grill.
Since the blow-out grill 10 is bonded to the base member 14 with the screw 12, the drain grill 7 and the through-flow fan 4 which also function as a stabilizer that influences the aerodynamic performance of the through-flow fan 4 are attached.
There was a problem that the interval y between and was not constant.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above problems, and its gist is to form a stabilizer for forming an air passage of a once-through fan integrally with an outlet grill. Then, the protrusion provided on the blowout grill is inserted and fitted into the fitting portion provided on the base member, and the locking grille provided at the lower portion of the base member and having a claw at the tip is provided on the blowout grill. The blow-out grill is mounted on the base member by fitting and locking the tapered positioning portion, and there is provided a blow-out grill mounting structure in an air conditioner.

[0007]

In the present invention, since the above-mentioned structure is provided, the projection grille is inserted and fitted in the fitting portion, and the tapered positioning portion is fitted and locked in the locking projection so that the blow-out grill can be formed. It is attached to the base member.

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. The blow-out grill 23 is integrally formed with a stabilizer 26 that forms an air passage of the cross-flow fan 4, and the stabilizer 26 cooperates with a wall 24 and a top surface of the blow-out grill 23 which are installed upright in parallel with each other at a distance. A gutter 28 that receives the drain dropped from the heat exchanger 3 is configured. The other end of the wall 24 is bent obliquely upward to form a projecting piece 29, and the projecting piece 29 is formed by bending the other end of the rain gutter 27 formed on the base member 20 obliquely downward. It is adapted to engage the part 30.

Further, as shown in FIG. 2B, a locking projection 21 having a claw 31 at its tip is provided on the lower portion of the base member 20,
The locking projection 21 is locked to a tapered positioning portion 22 provided on the outlet grill 23. Other configurations are shown in FIG.
It is similar to the conventional one shown in.

In order to mount the blow-out grill 23 on the base member 20, the projecting piece 29 is inserted and fitted into the fitting portion 30 and engaged therewith, and the locking projection 21 is taperedly positioned. The blow-out grill 23 is accurately positioned and attached to the base member 20 by fitting and locking the portion 22. Thus,
The installation work of the blow-out grill 23 to the base member 20 does not require the conventional screwing work, and therefore can be performed extremely easily and quickly, and the interval y between the stabilizer 26 and the flow-through fan 4 integrally formed with the blow-out grill 23 can be increased. Is maintained constant, and deterioration of the aerodynamic performance of the once-through fan 4 can be prevented.

[0011]

According to the present invention, the stabilizer is formed integrally with the blowout grill, and the protrusion provided on the blowout grill is inserted and fitted into the fitting portion provided on the base member and is provided on the base member. Since the tapered positioning portion provided on the blowing grill is fitted and locked in the locking projection, the blowing grill is accurately positioned and mounted on the base member. Further, unlike the conventional case, no screwing or screwing work is required, so that the work of mounting the blowout grill can be performed easily and quickly, and the cost can be reduced. Further, since the distance between the once-through fan and the stabilizer can be maintained constant, it is possible to prevent the aerodynamic performance of the once-through fan from being deteriorated.
