Description

  The present invention relates to a heat insulating structure for an up-and-down air direction changing blade of an air conditioner that performs indoor cooling.

  Generally, an air outlet of an indoor unit of an air conditioner is provided with an up / down air direction change blade and a left / right air direction change blade in order to control the direction of cool and warm air, and a plurality of heat insulating materials are provided on the up / down air direction change blade. The thing which prevented the dew condensation produced on a blade | wing by sticking, and the device which changed the wind direction of the upper and lower blades like a patent document by the center and right and left are also made | formed (for example, refer patent document 1).

  Also, due to the recent environmental efforts, it is necessary to separate the heat insulating material during recycling when pasting different types of heat insulating material. Therefore, the box made of the same material and the hollow cover are bonded and fixed in a hollow state. There is a method of forming a portion to form an air heat insulating structure and preventing condensation generated on the blade.

6 and 7 show a conventional method for adhering the up / down airflow direction changing blade in such a case. In the figure, the up / down airflow direction changing blade 10 has a hollow lid 10a and a box portion 10b bonded to each other with an adhesive. In this case, the adhesive 12 may protrude.
JP-A-7-234006

  However, in the operation of bonding and fixing the box portion formed in a box shape and the hollow lid, when these two parts are combined, if the adhesive protrudes from the peripheral edge alignment portion, a wiping operation in the subsequent process is required. Or when the wiping is insufficient, an adhesive mark may remain on the appearance surface.

  In order to solve the above-mentioned conventional problems, the air conditioner vertical airflow direction change blade according to the present invention forms a hollow part by bonding and fixing a box-shaped box part and a hollow lid, and the upper and lower parts of the hollow structure It is possible to prevent the adhesive from sticking out from the edge-matching portion by setting the edge rib for bonding at least inside the periphery of either the box portion or the hollow lid.

  The vertical airflow direction changing blade of the present invention is such that when the two parts are combined in an operation of bonding and fixing the box part having a box-like adhesive strength equivalent to the conventional one and the hollow lid, the adhesive is removed from the peripherally aligned part. Since the protrusion can be prevented, it is possible to prevent an adhesive mark from remaining on the appearance surface when the wiping operation in a subsequent process or when wiping is insufficient.

  The present invention is an air conditioner including a blower fan, a blowout port that blows out the wind generated by the blower fan, and a vertical airflow direction change blade on the blowout port, wherein the vertical airflow direction change blade includes a box portion and a hollow Adhering and fixing the lid to the box to form a box having a hollow portion, and bonding the hollow lid by installing a peripheral rib for bonding at least inside the peripheral edge of either the box portion or the hollow lid When the two parts are combined in the fixing operation, even if the adhesive protrudes from the peripheral rib, it can be accommodated in the outer peripheral edge to prevent the adhesive from protruding to the design surface, and the effect of the invention can be obtained. it can.

  In addition, the use of a dope cement in which the same material as the base material is used as an adhesive for bonding between the box and the hollow lid, which has high adhesive strength and does not require special dedicated equipment, so it is lower in development. The effects of the invention can be obtained with low cost and short development time. Further, after the solvent is volatilized, the material is composed of only the same material as the base material, so that recycling can be facilitated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a front view of an air conditioner according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line BB in FIG. 3 is an exploded perspective view of the box portion and the hollow lid of the air conditioner blades of the air conditioner, FIG. 4 is a cross-sectional view thereof, and FIG. 5 is a detailed view of the main part of FIG. Indicates the part.

  In FIG. 2, the blower outlet 3 is provided in the lower part of the air conditioner main body 5, and the ventilation fan 4 and the heat exchanger 6 are attached to the upper side. And the up-and-down wind direction change blade | wing 1 which can be rotated and moved is arrange | positioned in the front side of the blower outlet 3, and the up-and-down air direction change blade | wing 1 adhere | attaches the box part 1b and the hollow cover 1a of the same material, and is flat and slightly. It is formed in a box shape having warpage.

  Next, the structure of the adhesive fixing part of the up-and-down wind direction change blade | wing 1 is demonstrated using FIGS. As shown in the figure, the vertical wind direction changing blade 1 is configured to provide a hollow portion 2 from a hollow lid 1a and a box portion 1b, and the hollow lid 1a and the box portion 1b are changed in the vertical wind direction. The hollow lid peripheral rib 7 formed inside the blade 1 and the vicinity of the box peripheral rib 8 are bonded and fixed with an adhesive 9.

  The operation and action of the air conditioner configured as described above will be described. During the cooling operation of the air conditioner main body 5, in the operation mode in which the air that has passed through the heat exchanger 6 and is cooled is directed upward by the blower fan 4 at the air outlet 3, Due to the temperature difference, dew condensation is likely to occur on the outside of the up / down airflow direction changing blade 1. In that case, the dew condensation at the time of cooling can be prevented by the heat insulation effect of the hollow part 2 comprised by the cover 1a for hollows of the up-and-down air direction change blade | wing 1 and the box part 1b.

  With the above configuration, in the formation of the up-and-down wind direction changing blade 1, since the adhesive 9 can be prevented from sticking out to the external surface by applying the adhesive inside, there is no fear that the user will see the adhesive during operation. The appearance can be improved. Further, since there is no process of protruding or wiping off the adhesive when the two parts are combined by the operator, the number of assembling steps can be reduced.

  In the present embodiment, a hollow lid peripheral rib 7 having a height substantially in contact with the box portion 1b is provided inside the peripheral edge of the hollow lid 1a, and a hollow lid peripheral rib is provided inside the peripheral edge of the box portion 1b. A box peripheral edge rib 8 having a low degree of contact in parallel with 7 is provided. These combinations are not limited to this, and may be configured such that peripheral ribs having a height such as the hollow lid peripheral rib 7 are provided on only one of them.

  As the adhesive 9, it is preferable to use a dope cement in which the same material is dissolved. That is, if a dope cement in which the same material as the base material is dissolved is used as the adhesive 9, the adhesive strength is high and no special dedicated equipment is required. Therefore, the development cost can be reduced and the development time can be shortened. The effect can be obtained, and after the solvent is volatilized, the structure is made of only the same material as the base material, so that recycling can be facilitated.

  The heat-insulating structure of the air conditioner of the present invention requires a heat-insulating structure because it can improve the design, reduce the variation in completeness of components, and reduce the environmental load while maintaining the same heat-insulating performance as before. Applicable to various devices and devices.
