Description

  The present invention relates to a decorative cover processing technology for covering piping such as a refrigerant pipe, a drain hose, a ventilation hose, and an electric wiring disposed between an indoor unit for air conditioning having a ventilation function and an outdoor unit for air conditioning outside. In detail, in the corner cover fixed to the wall outer surface in a state of covering the bent portion of the piping led out through the wall through hole through the posture along the wall outer surface, the ceiling wall portion facing the through hole is for ventilation. The present invention relates to a corner decorative cover in which a ventilation opening having a size through which piping can be inserted is formed, and a lid portion in which a plurality of ventilation holes communicating with the ventilation opening are formed at positions opposite to the ventilation opening.

The corner cover of a conventional decorative cover for a corner forms a ventilation opening in the ceiling wall portion of the corner cover opposite to the through hole of the wall through which piping such as a refrigerant pipe and a drain hose passes, and in the ventilation opening Insect-proof lids with numerous ventilation slits formed at opposite positions are formed integrally with the corner cover, and the corner cover is piped for natural ventilation or forced ventilation. The tip of the ventilation pipe that is passed through the through-hole together with the pipe is disposed so that the opening of the ventilation pipe faces the ventilation opening of the corner cover so as to face the ventilation opening of the corner cover. Indoor ventilation was naturally or forcibly performed through a slit (for example, refer to Patent Document 1 or Patent Document 2).
Japanese Patent No. 3280579 JP2000-171055

  However, in the case of the conventional corner cover of the corner cover, in the case of an air conditioning system that ventilates the room by natural ventilation, the flow of supply and exhaust air is gentle, so the position facing the ventilation opening on the ceiling wall of the corner cover In addition, even if a lid portion having a large number of ventilation slits is provided, the lid portion can be ventilated without causing a large resistance to ventilation, but is an air conditioning facility that ventilates the room by forced ventilation Since the indoor air is forcibly supplied or exhausted by a ventilation fan or the like, even if a large number of ventilation slits are formed in the lid, the lid is a great resistance to ventilation, so efficient supply of air is achieved. There was a risk that a large load could be applied to a ventilation device such as a ventilation fan.

  Further, in the air conditioning system having a forced ventilation structure having both an air supply pipe for taking outside air into the room and an exhaust pipe for discharging the room air to the outside as ventilation pipes, If the corner cover of the decorative cover is used, both the air supply piping and the exhaust piping are housed inside the corner cover, and air supply and exhaust are performed inside the corner cover. When ventilation is performed, the lid part becomes a resistance to ventilation, and indoor air that is forcibly exhausted from the exhaust pipe into the corner cover is not efficiently exhausted through the slits, but is exhausted into the corner cover. There is a fear that air is supplied in a short circuit from the supply air pipe (that is, the same air circulates without being effectively ventilated).

  For this reason, in an air conditioning system with a forced ventilation structure that has both an air supply pipe and an exhaust pipe, a through hole for the ventilation pipe is drilled in the wall separately from the through hole through which the pipes pass. The air pipe and the exhaust pipe are arranged apart from each other.

  In view of the above problems, the object of the present invention is a highly versatile device that can be used for various ventilation structures in both air conditioning equipment having a natural ventilation function and air conditioning equipment having a forced ventilation function. It is in providing a decorative cover for corners.
