Description

この発明は、ジョイントに関し、特に加湿装置の加湿通路等の配管を接続するジョイントに関する。   The present invention relates to a joint, and more particularly to a joint that connects piping such as a humidifying passage of a humidifying device.

従来、室外から加湿通路を介して室内に加湿空気を供給する加湿運転を行う加湿装置を備えた空気調和機がある(例えば、特開２０００−２８４１５８号公報(特許文献１)参照)。   2. Description of the Related Art Conventionally, there is an air conditioner including a humidifier that performs a humidifying operation for supplying humidified air from outside to a room through a humidifying passage (see, for example, Japanese Patent Laid-Open No. 2000-284158 (Patent Document 1)).

ところで、上記空気調和機では、室外の加湿装置と室内を接続するための加湿通路を壁に設けた穴に通している。この場合、壁面に対して直角に通した加湿通路を室外側の壁面に沿って配設しようとする場合、穴を出てから直角に曲げようとしても加湿通路に用いられるホースの最小曲げ半径が大きいために壁面から加湿通路が離れて固定しにくいという問題や、加湿通路を化粧ダクトで覆うなどができず、外観のよい施工ができないという問題がある。   By the way, in the said air conditioner, the humidification channel | path for connecting the outdoor humidifier and room | chamber interior is passed through the hole provided in the wall. In this case, when a humidifying passage that passes through the wall at a right angle is to be arranged along the wall surface on the outdoor side, the minimum bending radius of the hose used in the humidifying passage is not limited even if it is bent at a right angle after leaving the hole. There is a problem that it is difficult to fix the humidification passage away from the wall surface because it is large, and there is a problem that the humidification passage cannot be covered with a decorative duct and construction with good appearance cannot be performed.

そこで、この加湿通路の屈曲箇所において、ジョイントを用いて直線状の加湿通路同士を略直角に接続することが考えられる。しかしながら、このジョイントは、一般にインジェクション成形により形成されるために内側のコーナーに角部があり、この内側コーナーの角部によって加湿空気の流れが乱れて、圧力損失や騒音が大きくなると共に、圧力変動により結露が生じ易くなるという問題がある。
特開２０００−２８４１５８号公報 Therefore, it is conceivable to connect the straight humidification passages at a substantially right angle by using a joint at the bent portion of the humidification passage. However, since this joint is generally formed by injection molding, there are corners at the inner corners, and the corners of the inner corners disturb the flow of humidified air, increasing pressure loss and noise, and pressure fluctuations. Therefore, there is a problem that condensation easily occurs.
JP 2000-284158 A
