[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit structure of an air conditioner which prevents a dew condensation phenomenon occurring around an outlet of an indoor unit.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6, an indoor unit 1 of an air conditioner draws indoor air from a suction port 3 provided at an upper portion of a front case 2, and communicates with an internal heat exchanger 4. After the heat exchange, the air is blown into the room as cold air or hot air from an air outlet 5 provided at a lower portion of the front case 2. Such an indoor unit 1 generally has a peripheral portion 6 (hatched portion) of the outlet 5 of the front case 2 decoratively painted in a different color from the other portions to improve the appearance. In this case, a masking process is applied to the front case 2 in advance,
Only the peripheral portion 6 of the outlet 5 will be painted.

By the way, a heat insulating material is provided on the inner surface of a unit back plate 8 which defines an outlet passage 7 extending from the inlet 3 to the outlet 5 in order to prevent dew condensation caused by air cooled by the heat exchanger 4. 9 is pasted. The most downstream portion 1 of the blowing passage 10 formed by the heat insulating material 9
In FIG. 7A, a flocked heat-insulating rubber member 12 in which bristles 11 having water absorbency are implanted on the surface as shown in FIG.
3 are provided. According to this configuration, when the air cooled by the heat exchanger 4 comes into contact with the high-humidity air that has entered from the outlet 5, dew condensation that occurs near the outlet 5 causes the bristle 11 of the flocked heat-insulating rubber member 12. Is absorbed and caught by water. Therefore, the condensed water is prevented from dropping from the outlet 5.

[0004]

However, in the indoor unit structure having the above structure, the following problems occur.

[0005]

As shown in FIG. 7, the flocked heat insulating rubber member 12 has three surfaces 12a, 12b, 12c facing the air outlet passage 10.
It is manufactured by applying an adhesive to and applying the hair 11 to the applied portion. In this adhesive application operation, since it is difficult to mask the heat-insulating rubber member 12 formed elongated along the outlet 5 along the longitudinal direction, the portion where the flocking 11 is unnecessary (the rubber member 12 is replaced with the rib of the bottom plate 15) 16
The adhesive may wrap around to the portion where the hair is implanted, and the hair may be implanted to the unnecessary portion. Then, since the hairs 11 are in the way and it is difficult to fit the rubber member 12 to the ribs 16, it is necessary to remove the hairs in the unnecessary portion by the brushing or the like in a later step. Therefore, extra steps are increased, and the production time is increased and the cost is increased. Further, since the sealing material 13 must be provided between the flocked heat insulating rubber member 12 and the heat insulating material 9 of the blowing passage 10, it is disadvantageous in terms of cost.

An object of the present invention, which has been made in view of the above circumstances, is to provide a bonding method for bonding and fixing hair to a flocked heat insulating rubber member.
Adhesive spills into unnecessary parts during the mounting process
In addition to ensuring that there is no blowing passage and flocked heat insulating rubber member
It is an object of the present invention to provide an indoor unit structure of an air conditioner which can eliminate the need for a seal member interposed between the air conditioner and the air conditioner.

[0008]

In order to achieve the above-mentioned object, the present invention provides a method of forming an indoor unit at an air outlet with a heat insulating material.

You.

[0013]

The details of the corner section 18 are shown in FIGS.
Shown in As illustrated, the decorative cover 19 at a predetermined insulation distance t ₂ on the corner portion 18 of the side plate 17 is detachably attached. That is, the corner of the side plate 17
The portion 18 corresponds to the inner back surface plate , and the decorative cover 19 corresponds to the outer surface plate, and the corner portion 18 and the decorative cover 19 constitute a casing plate. Corner section 1
Numeral 8 is formed so as to be recessed by “the thickness t ₁ of the decorative cover 19 + the heat insulating interval t ₂ ”, and when the decorative cover 19 is attached, it is flush with the other parts.
The decorative cover 19 is configured by integrally forming a curved member 19a that goes from the front surface to the bottom surface and a fan-shaped member 19b that forms a side surface.

At the edge of the fan-shaped member 19b of the decorative cover 19, claw members 20 are provided. At the tips of the claw members 20, a hook portion 21 having a round and thick plate is formed. As shown in FIG. 3, the claw member 20 is formed obliquely along the mounting direction 21 in order to enhance the mountability when the decorative cover 19 is mounted on the corner portion 18 of the side plate 17. Specifically, since the decorative cover 19 is attached at an angle of 45 degrees from below, the claw member 20 is also formed at an angle of 45 degrees. Also, the edge portion of the curved portion 19a of the decorative cover 19, toward the inside as shown in FIG. 4 and the rib 22 is provided for forming a heat-insulating spacing t _2, spaced at its rib 22 Hook member 2 inside
3 are provided. These hook members 23 hold the edges of the opposed corners 18 of the unit 1 when the decorative cover 19 is fitted.

On the other hand, a claw hole 24 for receiving the claw member 20 of the decorative cover 19 is formed in a corner portion 18 of the side plate 17. These claw holes 24 are formed to be inclined downward at an angle of 45 degrees in order to enhance the attachment of the decorative cover 19. Further, as shown in FIG.
Is formed so as not to penetrate the side plate 17 from outside to inside. This prevents internal cooling air from leaking outside through the claw holes 24.

According to the above configuration, the cool air transmitted from the inner surface of the corner portion 18 of the side plate 17 to the outer surface of the decorative cover 19 due to the cooling air blown out from the outlet 5 as shown in FIG. It is blocked by the heat insulating interval t ₂ which is formed between. Therefore, the outer surface of the decorative cover 19 is not excessively cooled, and the dew condensation phenomenon occurring on the surface of the decorative cover 19 is prevented. If the decorative cover 19 is made of a material having a small thermal conductivity and a high heat insulating property, the dew condensation phenomenon which is effectively generated on the surface of the decorative cover 19 can be effectively performed without performing excessive heat insulating processing on the corner portion 18 of the side plate 17. Can be prevented.

Further, since the decorative cover 19 is formed as a separate component from the side plate 17 and the front case 2, the masking process, which is conventionally required, is not required, and the cost can be reduced. The cutting line 14 is not disturbed. In addition, if a number of types of colors of the makeup cover 19 are prepared in advance, by appropriately incorporating these, the indoor unit 1 in which the portion 6 around the outlet 5 has a different color can be easily obtained.
Can be manufactured, and color variations are facilitated. Further, the corner portion 18 is formed to be recessed by a predetermined amount,
When the decorative cover 19 is mounted thereon, it becomes flush with the other parts, so that the aesthetic appearance of the indoor unit 1 is not impaired by the double casing structure described above. Further, since the decorative cover 19 is attached to the corner portion 18 by the plurality of claw members 20 and the hooking members 23, the decorative cover 19 does not easily come off even after assembly and is resistant to vibration. It does not cause any trouble.

[0019]

As shown in FIG. 6, at the outlet 5 of the indoor unit 1, hair 11 having water absorbing property on the surface thereof is connected to the most downstream portion 10a of the outlet passage 10 formed by the heat insulating material 9. The planted flocking heat insulating rubber member 12 is provided. The feature of the present embodiment is that, as shown in FIG. The projections 25 having the surface portion implanted thereon are integrally formed so as to be superimposed thereon.

The flocked heat insulating rubber member 12 is formed to be elongated along the outlet 5, and is provided on the bottom plate 1 of the indoor unit 1.
5 is fitted to the rib 16 provided. On the other hand, the heat insulating material 9 of the outlet passage 10 is attached to a housing 26 in the indoor unit 1. A hook 16 (not shown) is formed on the rib 16 of the bottom plate 15.
Is adapted to be engaged with a claw hole (not shown) opened at the front end. By this engagement, as shown in FIG. 8, the flocking heat-insulating rubber member 12 fitted into the rib 16 of the bottom plate 15
Is superimposed on the heat insulating material 9 on the most downstream portion 10a of the outlet passage 10.

According to the above configuration, the flocked heat insulating rubber member 1
In the adhesive application step when the hair 11 is bonded and fixed to 2, the projection 25 also functions as a masking member,
The adhesive does not sneak into unnecessary portions (the fitting portions of the ribs 16). Therefore, troublesome flocking removal work does not need to be performed in a post process. In addition, the adhesive applied surface is conventionally the same as FIG.
As shown in FIG. 8, the three surfaces 12a, 12b, and 12c were required.
Since only e is used, the adhesive application step can be simplified. In addition, since the protrusion 25 is provided continuously on the most downstream portion 10a of the outlet passage 10, conventionally,
Since the sealing member 11 interposed between the blowing passage 10 and the heat insulating rubber member 12 also serves as the sealing member 11, the sealing member 11 becomes unnecessary.

[0023]

According to the present invention, as described above, the following excellent effects can be obtained.

[0024]

(1) A flocked and heat-insulated rubber member is provided at the outlet of the indoor unit so as to be continuous with the most downstream portion of the blow-out passage formed of a heat insulating material. Since the projections with the surface implanted are integrally formed so as to overlap with each other, the projections also serve as masking members in the adhesive application step when the hairs are adhesively fixed to the implanted heat insulating rubber member. Also, the adhesive does not sneak into unnecessary parts. Therefore, it is not necessary to perform a troublesome flocking operation in a later step, and the cost can be reduced. In addition, since the above-mentioned projection also serves as a sealing material conventionally interposed between the blow-out passage and the heat insulating rubber member, the sealing material becomes unnecessary and the cost is reduced.
