  Since the outer surface side of the front panel is exposed to the outer surface of the air conditioner, design is emphasized. However, in the air conditioner described in Patent Document 1, since the front panel is formed in a plate shape, when pursuing the design of the outer surface side of the front panel, the shape of the inner surface side that inevitably becomes the air guide surface is increased. As a result, the air from the outlet cannot be guided in an appropriate direction. On the other hand, if the shape on the inner surface side of the front panel is determined with emphasis on the air guide surface, the design on the outer surface side will be deteriorated. Thus, it has been difficult to achieve both design and functionality.

  An object of this invention is to provide the air conditioner provided with the wind guide panel which can make a design surface and a functional surface compatible, the manufacturing method of a wind guide panel, and a wind guide panel in view of the said subject.

  In order to achieve the above object, the present invention is an air guide panel that adjusts the direction of air blown from an air conditioner, and a foam layer is laminated on the other surface side of a frame material that forms one surface side of the panel. In the wind guide panel, the foam layer surface is formed in a wind guide shape capable of guiding air in a predetermined direction. By laminating the foam layer on the frame material forming the one surface side of the panel, the one surface side and the other surface side can be formed in different shapes. Therefore, even when the frame material forming one side of the panel is molded with emphasis on design, the foam layer laminated on the inner side can be formed in the desired wind guide shape, so the wind guide direction can be freely set Can be set. In this way, the foam surface can always function as an air guide surface.

  Moreover, heat insulation can be exhibited by providing a foam layer in a wind guide panel. For example, if one side of the wind guide panel is in contact with the outside air outside the casing of the air conditioner and cold air blown out from the air conditioner is in contact only with the other side of the wind guide panel, dew condensation on the one side of the wind guide panel However, the wind guide panel of the present invention can effectively prevent condensation due to the heat insulating effect of the foam layer.

  The air conditioner as described above includes, for example, a casing having a blowout port for blowing out air and a wind guide panel that covers the blower port, and the wind guide panel is a casing in the vicinity of the upper end edge or the lower end edge of the blowout port. There is an air conditioner that is rotatably provided around a rotation axis that is set in parallel with the left-right direction. When the wind guide panel takes an attitude of opening the air outlet, the outside air touches one side of the wind guide panel, and the cold air blown from the air conditioner comes into contact with the other side. In such an air conditioner, if the wind guide panel has a structure in which a foam layer is laminated on one surface side of the frame material, and the foam layer surface always functions as a wind guide surface, the heat insulation of the foam layer is achieved. Condensation can be effectively prevented by the effect.

  Moreover, the wind guide panel of the present invention includes a casing having a blowout port for blowing out air and a wind guide panel covering the blower port, and the wind guide panel is in the casing lateral direction in the vicinity of the upper end edge or the lower end edge of the blowout port. The wind guide panel is provided with a seal portion connected to the wind guide panel on the outer side of the turn axis, and the wind guide panel and the seal portion are rotated. The air provided in the casing has a contact portion that rotates around the movement axis and contacts the seal portion to close the gap between the seal portion and the casing when the air guide panel is in a posture to open the air outlet. It can be used for a harmony machine. When the wind guide panel is in a position to open the air outlet, the gap between the upper or lower end of the wind guide panel and the casing is closed, so that air can be guided more accurately without leaking air from the gap. While it can be performed, the temperature difference between the one surface side and the other surface side of the wind guide panel becomes larger, but according to the wind guide panel of the present invention, condensation can be effectively prevented.

  Moreover, the wind guide panel of this invention can be used also for the air conditioner by which the wind guide panel was divided into 2 parts up and down. That is, a casing having a blowout port for blowing out air and a wind guide panel that covers the blowout port of the casing and its peripheral portion, and the wind guide panel is positioned above and above the ventilation portion that allows the air blown out from the blowout port to pass therethrough. The extension panel body covering the peripheral part of the air outlet and the cover panel body closing the ventilation part, and the air guide panel is in the vicinity of the lower end edge of the air outlet at the lower end part thereof. The cover panel body is rotatably attached to the casing at the upper end thereof, and is provided so as to be rotatable with respect to the extension panel body around a rotation axis set parallel to the casing left-right direction. The body is provided with a seal portion connected to the cover panel body above the rotation axis, the cover panel body and the seal portion rotate about the rotation axis, and the cover panel body is blown. When taking attitude for opening the mouth, the abutment portion abuts on the seal portion blocks the space between the seal portion and the casing can be suitably used for an air conditioner provided in the casing. Further, a sealing material that seals a gap between the wind guide panel and the casing when the wind guide panel is rotated to take an attitude of opening the air outlet is disposed on at least one of the wind guide panel and the casing. be able to.

  The foam layer may be an open-cell body, but closed-cell bodies are preferred because of their higher heat insulation properties. Moreover, as a raw material of a foam layer, although not limited, a synthetic resin, natural, or a synthetic rubber is illustrated. Examples of the synthetic resin component include polyurethane, vinyl chloride resin (PVC), polypropylene, and polyethylene, and polyurethane is particularly preferable. If the foam layer is made of polyurethane foam, a light guide panel that is lightweight and has excellent mechanical strength can be obtained.

  Such a wind guide panel is formed by forming a concave frame material forming one surface side of the panel, placing the frame material on a first mold having a recess corresponding to the outer shape of the outer surface of the frame material, and then introducing the frame material. A frame material is sandwiched between a second mold having a recess corresponding to the wind shape, and a foam material is injected into a space surrounded by the frame material and the recess of the second mold to form a foam. A wind guide panel in which a foam layer is laminated can be manufactured. The foam layer may be chemically foamed using a foaming agent, or may be foamed by mechanically entraining air during molding.

  According to the present invention, the one surface side and the other surface side can be formed in different shapes by laminating the foam layer on the frame material forming the one surface side of the panel. Therefore, even when the frame material forming one side of the panel is molded with emphasis on design, the foam layer laminated on the inner side can be formed in the desired wind guide shape, so the wind guide direction can be freely set Can be set. Moreover, a heat insulation effect is exhibited by the foam layer, and condensation on the surface of the wind guide panel can be prevented.
