Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an air conditioner equipped with a front decorative panel attached to the outer box body.

[Conventional technology]

Figures 5 and 6 are for example Jitsukō 54-26680.
1 shows a sectional view and an exploded perspective view of an indoor unit of a conventional air conditioner shown in the publication. In FIGS. 5 and 6, reference numeral 1 designates a bulge 3 that forms the rear wall of the air passage 2 and a flange 4 that protrudes rearward from the outer periphery of the front end of the bulge 3, which are integrally made of synthetic resin. The outer box body 5 is a front decorative panel that covers the front opening of the main body 1 that is fitted and fixed to the front part of the main body 1, and this panel 5 is made of a synthetic resin integrally molded product and has an air outlet 6 at the top. However, suction ports 7 are opened at the bottom. Reference numeral 8 denotes a blow-off nozzle mounted on the front surface of the main body 1 toward the blow-off port 6, and a guide plate 10 is integrally formed at the lower rear end of the nozzle 8. Reference numeral 9 denotes a rear cover integrally formed with a frame portion 10 that expands toward the front. The rear end surface of the rear cover 9 is fixed to the boss portion 11 together with a locking piece 13 by screws. Reference numeral 12 denotes a mounting plate for installing the indoor unit indoors, and the mounting plate 12 holds the rear cover 9 via the locking piece 13 mentioned above. 1
4 is a heat exchanger installed in the air passage 2 adjacent to the suction port 7; 15 is a nozzle 8 in the air passage 2 and the heat exchanger 1;
This is a cross-flow type blower installed between 4. The indoor unit of the conventional air conditioner configured as described above sucks indoor air from the suction port 7 by driving the blower 15, exchanges heat by passing it through the heat exchanger 14, and then blows the indoor air through the nozzle. The air is blown into the room from the air outlet 6 via the air outlet 8.

And the front decorative panel 5 of the conventional air conditioner
is an integrally molded synthetic resin product having an air outlet 6 and an inlet 7, which is fitted into the flange portion 4 of the main body 1 and fixed to the flange portion 4 with screws or the like.

[Problem that the invention attempts to solve]

A conventional air conditioner is configured as described above.
Since the front decorative panel is an integrally molded product, when changing the design due to model changes, etc., the entire front decorative panel must be molded with a new mold, which is expensive and requires a new front decorative panel to fit the main body and nozzle. Compared to the previous front decorative panel, there was a problem that it was difficult to match.

This invention was made in order to solve the above-mentioned problems, and the purpose is to obtain an air conditioner equipped with a front decorative panel whose design can be easily and inexpensively changed by changing the model or the like.

[Means for solving problems]

In the air conditioner according to this invention, the front decorative panel is divided into a decorative frame forming the outer shape and a suction grill having a suction port, and the claws of the suction grill are engaged with the U-shaped holes of the decorative frame. The suction grill and decorative frame are assembled together by screwing the suction grill's screw-fixing bosses to the decorative frame, and then fitting the suction grill's welding bosses into the holes in the decorative panel and integrating them by heat welding. are fitted and fixed.

[Effect]

The air conditioner according to this invention has a decorative frame and a suction grille having an inlet, which are constructed separately, and the front decorative panel is constructed by fixing these together.
When changing the model, by changing only the suction grill, the mold can be made smaller.
In addition, by not changing the decorative frame that fits and secures to the outer case body, the decorative frame can be easily and securely attached to the outer case body, and the suction grill and the decorative frame can be fixed together with the claw pieces. It can be made relatively simple and strong by using a combination of screwing the locking boss in the shaped hole and heat welding the boss.

〔Example〕

An embodiment of this invention is shown below in Figures 1 to 4.
The diagram will be explained.

In FIG. 1, the same reference numerals as in FIGS. 5 and 6 indicate the same or corresponding parts, and 16 and 22 are a suction grill and a decorative frame made of integrally molded synthetic resin. In the suction grill 16, a projecting wall 18 projects rearward from the upper side and both sides of the outer periphery of a front surface part 17 having the suction port 7, and the projecting wall 17 is formed in the shape of an inverted groove with an open tongue surface. A plurality of claw pieces 19 protrude inside the front part 17, and a plurality of screwing bosses 20 and a plurality of welding bosses 21 protrude rearward from the inner surface of the front part 18. Decorative frame 2 that forms the outer shape of the front decorative panel 5 and the discharge port
2, a peripheral wall portion 25 forming the outer shape of the front decorative panel protrudes rearward from the entire outer periphery of a support frame 24 having a hole 23 corresponding to the suction port 7, and the peripheral wall portion 25 has a U-shaped portion surrounding an elastic tongue piece 26. A hole 27 is formed at a position that matches the claw piece 19, and a screw hole 28 and a welding hole 29 are formed in the support surface 24 at a position that matches the bosses 20 and 21, respectively. Further, a discharge port 30 into which a blow-off nozzle (not shown) is fitted is formed at the lower side of the peripheral wall portion 25 of the decorative frame 22.

The front decorative panel whose main components are the suction grill 16 and the decorative frame 22 configured as described above,
By pushing the suction grille 16 into the decorative frame 22 from the front, the claw pieces 19 bend the elastic tongue pieces 26 inward and open the U-shaped holes 2 as shown in FIG.
7 into the U-shaped hole 27 as shown in Figure 2b.
engage with. Furthermore, since the screwing bosses 20 match the screwing holes 28 of the support frame 24, screws 31 can be inserted into the screwing holes 28 and tightened to the screwing bosses 20 as shown in FIG. Then, the screwing boss 20 is fixed to the support frame 24, and the protruding wall 18 is attached to the step 2 on the outer periphery of the peripheral wall portion 25.
Fit it onto 5a. Furthermore, the welding boss 21 is the fourth
As shown in Figure a, it fits into the welding hole 29 of the support frame 24, so by heating and crushing the part of the welding boss 21 that protrudes inside the support frame 24, as shown in Figure 4b, The front part 17 is fixed to the support frame 24, the suction grill 16 is completely fixed to the decorative frame 24, and the front decorative panel 5 of the bottom-blowing air conditioner is constructed.

Although not shown in the drawings, the front decorative panel 5 of this embodiment constructed as described above is similar to the conventional front decorative panel shown in FIGS. 5 and 6 for use in a bottom-blowing air conditioner. It is fitted and fixed to the front part of the outer box body provided in the indoor unit.

In the above embodiment, a bottom blowing air conditioner has been described, but this invention can also be applied to a top blowing air conditioner as shown in FIGS. 5 and 6.

[Effect of idea]

As explained above, according to the air conditioner of this invention, the front decorative panel is constructed by separating the two main members of the decorative frame forming the outer shape and the suction grille having the suction opening, so that it is possible to By being able to mold the suction grill with a mold that requires minimal design changes, it can be made at low cost, and a front decorative panel with many variations of designs can be obtained, and by not changing the decorative frame, it can be attached to the outer box body. This allows the front decorative panel to be easily and securely fitted to the outer box body, and the suction grille and decorative frame are fixed by engaging the claw pieces and the U-shaped holes, screwing the bosses, and screwing the bosses together. By using heat welding in combination, it is possible to achieve the effect of making it relatively simple and strong.
