It was. Also, when changing the wind direction with a single sheet, increasing the thickness of the center of the up / down wind direction changing blade and making the left and right thin causes sinking in the appearance of the support portion of the up / down wind direction changing blade, so the shape of the support portion is complicatedly formed. There was a need.

  In order to solve the above-described conventional problems, the air conditioner up / down air direction change blade of the present invention is formed by joining a box-shaped box part and a hollow cover to form a hollow part, and changing the up / down air direction of the hollow structure By using a blade, it is possible to maintain the same heat insulating performance as that of attaching a heat insulating material.

  The up-and-down airflow direction changing blade of the present invention can be expected to improve the appearance design and prevent variation in the degree of completeness of components while maintaining heat insulation performance equivalent to the conventional one, and also facilitate recycling of components.

  1st invention is an air conditioner which comprised the ventilation fan, the blower outlet which blows off the wind produced by the said blower fan, and the up-and-down air direction change blade | wing at the said discharge port, Comprising: The said up-and-down air direction change blade | wing is a box part And a hollow lid to form a box shape having a hollow portion, so that the heat insulation performance equivalent to the heat insulating material pasting is maintained in the hollow portion, and work for a plurality of conventional heat insulating material pasting operations is performed. The skill level of the worker is not required, so that stable quality can be ensured and man-hours can be reduced while preventing variations.

  The second invention uses vibration welding particularly for joining the box portion and the hollow lid of the first invention, and has high adhesive strength and is made of the same material for joining by melting the surface of the base material. Configuration is possible, and recycling can be facilitated.

  The third invention uses ultrasonic welding especially for joining the box portion and the hollow lid of the first invention, and has high adhesive strength and is made of the same material for joining by melting the surface of the base material. This makes it possible to facilitate recycling. Moreover, since the equipment is simpler than vibration welding, the effects of the invention can be obtained at a lower development cost.

  The fourth aspect of the invention uses an adhesive for bonding the box portion and the hollow lid of the first aspect of the invention, and has high adhesive strength and does not require special dedicated equipment, so that the development cost is lower. In addition, the effects of the invention can be obtained in a short development time.

  In the fifth invention, in particular, the bonding of the box portion and the hollow lid of the first and fourth inventions is performed using an adhesive, and a dope cement in which the same material as the base material is dissolved is used as the adhesive. Therefore, since the adhesive strength is strong and no special dedicated equipment is required, the effects of the invention can be obtained with a lower development cost and a shorter 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.

In addition, about the same part as the past, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In FIG. 2, the air conditioner body 5 has a blowout port 3 at the lower part of the front surface, and a heat exchanger 6 and a blower fan 4 are attached to the upper side of the blowout port 3. And the blowing port 3 is provided with an up-and-down air direction changing blade 1 having a hollow portion 2 formed therein.

  Next, the structure of the junction part of the up-and-down wind direction change blade | wing 1 is demonstrated using FIG. As shown in the figure, the up-and-down wind direction changing blade 1 is configured by joining a hollow lid 1a and a box portion 1b formed of the same material, and the hollow lid 1a and the box portion 1b are formed on the outer peripheral portion 7, 8 is formed by providing a hollow portion 2.

  As the bonding method, vibration welding, ultrasonic welding, or an adhesive is preferably used. In particular, a dope cement in which the same material is dissolved is preferably used as the adhesive. That is, if vibration welding is used, the adhesive strength is high, and it is possible to construct the same material for joining by melting the surface of the base material, thereby facilitating recycling.

  In addition, if ultrasonic welding is used, the adhesive strength is strong, and it is possible to configure the same material for joining by melting the surface of the base material, which can facilitate recycling and the equipment can be made easier than vibration welding. Since it is simple, the effects of the invention can be obtained at a lower development cost.

  Further, if an adhesive is used, the adhesive strength is strong and no special dedicated equipment is required. Therefore, the effects of the invention can be obtained with a lower development cost and a shorter development time.

  Further, if a dope cement in which the same material as the base material is dissolved is used as an adhesive, the adhesive strength is strong, and no special dedicated equipment is required. Therefore, the effects of the present invention can be achieved at a lower development cost and a shorter development time. In addition, after the solvent is volatilized, only the same material as that of the base material is used, so that recycling can be facilitated.

The operation and action of the air conditioner configured as described above will be described. During the cooling operation of the air conditioner 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. At that time, condensation during cooling can be prevented by the heat insulating effect of the hollow portion 2 constituted by the hollow lid 1a and the box portion 1b of the up-and-down air direction changing blade 1.

  With the above configuration, the heat insulating material can be omitted while maintaining the same heat insulating performance as the heat insulating material pasting, so there is no concern that the heat insulating material will be visible to the user during operation, and the appearance design can be improved. . Moreover, since there is no heat insulating material sticking process by an operator, it can be expected to prevent variations in the completeness of parts. Furthermore, since it is not necessary to separate heat insulating materials of different materials when disassembling parts, recycling is prepared and the environmental load can be reduced.

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