A plurality of suction grilles are fitted into the air suction opening. In that case, in most conventional suction grills, the lower end of each suction grill is hooked onto the engagement step formed in the dew pan of the evaporator, and then the upper end is hooked onto the hook formed on the front edge of the top plate of the housing. It is designed to be locked in the locking part of.
However, according to this method, in order to hide the locking part and ensure the parallelism of each suction grill, it is necessary to separately prepare a decorative rail and extend it across each suction grill, which reduces assembly work efficiency and costs. A review was required in this respect.

[Purpose of the invention] This invention was created in view of the above-mentioned conventional circumstances, and allows each intake grill to be neatly attached to the air intake opening without requiring separate parts such as decorative rails. An object of the present invention is to provide a suction grill mounting device for an air conditioner.

[Examples] Hereinafter, this invention will be described in detail with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows a front view of an air conditioner to which the suction grill mounting device according to the invention is applied, and FIG. 2 shows an exploded perspective view of the main parts thereof. According to this, this air conditioner has a housing including a top plate 1, a left side plate 2, a right side plate 3, and a back plate and a bottom plate (not shown), and a wind direction switching plate 4 is provided in a known manner at the front lower part of the housing. It is rotatably mounted. An evaporator 5 is installed in the housing 1 together with a cross flow fan (not shown), and a dew pan 6 is disposed below the evaporator 5. During cooling or heating operation, indoor air is drawn into the housing through an evaporator 5 from an air suction opening substantially formed by a top plate 1 and a dew pan 6, and a wind direction switching plate 4 is provided. The air is exhausted from an outlet (not shown), and according to this embodiment, for example, three suction grilles 7, 8, and 9 are connected to the evaporator using the top plate 1 and the dew pan 6 at the air suction opening. It is attached to cover the front of 5.

Since each of these suction grills 7, 8, and 9 has the same configuration, only one of them, the suction grill 7, will be described here. Suction grill 7

10b are both L-shaped hook members with their tips bent upwards (see Figure 3), and the lower two engaging male members 10c and 10d are opposite to the above, with their tips bent downwards. It consists of an L-shaped hook member (see Figure 4).

On the other hand, the front edge 1a of the top plate 1 bent at a substantially right angle and the front wall portion 6a of the dew pan 6 have a mechanism that allows the hook member to be slid in the horizontal direction (horizontal direction in FIG. 1). Coupling members 11 and 12 are provided, respectively. As illustrated in FIG. 3, the engagement receiving member 11 on the top plate 1 side has an attachment/detachment opening 11a formed substantially larger than the hook member 10a (or 10b), and a side thereof (the same The engagement groove 11b is provided with an engagement groove 11b that is continuous in the left direction in the figure. In this case, the engagement groove 11b has a depth dimension capable of engaging two hook members, the hook member 10a and the hook member 10b of the suction grill 8 adjacent thereto. On the other hand,
As illustrated in FIG. 4, the engagement receiving member 12 on the side of the dew pan 6 has a horizontal direction ( It consists of a substantially L-shaped locking piece that extends in the right direction in the figure. Like the engaging groove 11b, this locking piece 12 is also formed in a size that can lock two hook members, the hook member 10c and the hook member 10d of the suction grille 8 adjacent thereto. In addition,
Each locking piece 12 is located directly below the engagement groove 11b and is arranged to form a pair therewith.

Further, according to this invention, as shown in FIGS. 5 and 6, the side sides of the suction grilles 7 are provided with claw pieces 13 that protrude toward the sides of the adjacent suction grills 8. A joint portion 14 is formed. Similarly, on the side of the suction grill 8, there is also a claw piece 13 that can be engaged in the engagement step 14 of the adjacent suction grill 7, and a claw piece that protrudes from the other side, that is, the side of the suction grill 7. An engagement step 14 that engages with the engagement step 13 is formed. Although not shown, claw pieces 13 and engagement step portions 14 are similarly provided on both sides of the other remaining intake grille 9, respectively.

Referring again to FIG. 2, the suction grill 7 has a dust removal filter 15 that can be attached and detached from below. Although its mounting structure is not shown, it may be, for example, a pair of guide rails with a U-shaped cross section formed on the inside side of the suction grille 7. 15 is removably attached.
On the other hand, the front wall 6a of the dew pan 6 is connected to the top plate 1 through a suspension means, and in this embodiment, the suspension means is a suspension wire 16 with low ventilation resistance, and Pass this through the dust removal filter 15
It is located almost in the center of the That is, this hanging wire 16 is passed through the dust removal filter 15.
This also serves as a guide member for preventing the dust removal filter 15 from coming into contact with the evaporator 5 due to deformation or the like.

In the above configuration, each suction grill 7 to 9
are attached to the air suction opening on the front side of the evaporator 5 in such a way that they are packed sequentially from the left side in FIG. That is, first, the two upper hook members 10a, 10b of the suction grille 7 are attached to the openings 11a, 11 for attaching and detaching the corresponding two engagement receiving members 11, 11.

In that case, the upper left hook member 10b of the suction grille 8 engages in the same engagement groove 11b as the upper right hook member 10a of the suction grille 7 installed earlier, and the lower left hook member 10d is also installed first. It engages with the same locking piece 12 as the hook member 10c at the lower right of the suction grille 7. Similarly for the suction grille 9, the engagement receiving member 11,
11 and locking pieces 12, 12, and in this way, the three suction grilles 7 to 9 are arranged side by side in order from the left side.
Along with this, each claw piece 13 is connected to the engaging step portion 14 of the adjacent suction grill, as shown in FIG.
The parallelism of each intake grille is maintained.

Further, since the hanging wire 16 is arranged almost along the center of the dust removal filter 15, even if the filter 15 is warped, it will not come into contact with the evaporator 5.

In the above embodiment, the suction grille is mounted on the left side in FIG. 1, but it is of course possible to change it to the right side. In addition, hook members 10a to 1
Regarding 0d, unlike the above example,
The upper two hook members 10a, 10b may be bent downward, and the lower two hook members 10c, 10d may be bent upward. Of course, in this case, the engagement receiving member 11 has a shape with its top and bottom reversed, and
The lower two hook members 10c and 10d are locking pieces 12
It will engage the lower edge of.

[Effect] As is clear from the above description of the embodiment, according to this invention, the suction grill can be slidably engaged with the air suction opening of the housing, and the hook members of each adjacent suction grill are the same. The parallelism of each suction grill can be maintained by providing a claw piece and an engaging stepped portion that fit together between the sides of each suction grill. They can be arranged side by side in an orderly manner. Furthermore, since the hook member and its receiving member are hidden by the suction grille, there is no need to separately attach a decorative rail or the like as in the conventional case, thereby improving assembly workability and further reducing costs.
