A joint part provided with a hole for a passage of a refrigerant on a tapered surface integrally formed by drawing including a stepped reduced diameter part having a passage hole, a desiccant filled in the fuselage, and an outflow of the desiccant A filter to prevent and a strainer inserted at the tip of the joint, and the opening of the capacitor into which the receiver dryer joint is inserted communicates with the refrigerant inflow passage and the outflow passage. The shape and the inner surface shape of the opening of the capacitor are provided with stepped holes to define a space for receiving an O-ring that seals between the two.

本発明のレシーバドライヤ一体型コンデンサは、空調装置の他の構成要素である冷媒のコンデンサに対して、シール用のＯリングを継手部により一体に組み付けて組立体を構成することができる。この構成により空調装置の小型軽量化とコストダウンを達成することができる。   The receiver / dryer integrated capacitor of the present invention can be configured by integrally assembling a sealing O-ring with a joint portion with respect to a refrigerant capacitor which is another component of the air conditioner. With this configuration, it is possible to reduce the size and weight of the air conditioner and reduce the cost.

図１は、コンデンサ１にレシーバドライヤを一体にした組立体の他の例を示す。
コンデンサ１は、２本の冷媒通路２，３を有し、その開口部４にレシーバドライヤの継手部が挿入され、Ｏリング５，６でシールされる。コンデンサ１に対してレシーバドライヤ１０ａは取付金具７で固着される。 FIG. 1 shows another example of an assembly in which a receiver dryer is integrated with a capacitor 1.
The capacitor 1 has two refrigerant passages 2 and 3, and a receiver dryer joint is inserted into the opening 4 of the condenser 1 and sealed by O-rings 5 and 6. The receiver dryer 10 a is fixed to the capacitor 1 with a mounting bracket 7.

レシーバドライヤ１０ａは、金属材を鍛造加工した胴体１００と、胴体１００の開口端側に形成される継手部１１０を有する。胴体１００の内部には、乾燥剤１２０が充填され、不織布等でつくられるフィルタ１３０が挿入される。フィルタ１３０の反対側にはパンチングメタル等でつくられる補強板１４０が挿入され、ノッチ又はスピニング加工部Ｋ１で固定される。 The receiver dryer 10a includes a body 100 obtained by forging a metal material, and a joint portion 110 formed on the opening end side of the body 100. The body 100 is filled with a desiccant 120 and a filter 130 made of a nonwoven fabric or the like is inserted. On the opposite side of the filter 130 is inserted reinforcing plate 140 made of punching metal or the like, it is fixed in a notch or spinning unit K 1.

継手部１１０は、先細りのテーパー形状に形成され、先端の開口部には、プラスチック材を一体成型してつくられるストレーナ１５０が取付けられ、流出する冷媒の異物の通過を防ぐ。テーパー面には、冷媒が流入する穴１１２が形成される。   The joint portion 110 is formed in a tapered shape, and a strainer 150 formed by integrally molding a plastic material is attached to the opening at the tip, thereby preventing passage of foreign matters from the refrigerant flowing out. A hole 112 through which the refrigerant flows is formed in the tapered surface.

図２は、本発明の他の実施例に係るレシーバドライヤ１０ａの胴体１００の先端の継手部１１０をコンデンサ１に対して組付けるための構造を示す。
継手部１１０は、絞り加工により成形される先細りのテーパー部１１１を有し、テーパー部１１１に冷媒通過用の穴１１２が設けられる。テーパー部１１１の先端には首部１１４が形成される。
胴体１００とテーパー部１１１の間には、第１の段付部１１６と第１の縮径加工された円筒部１１７が形成される。そして、円筒部１１７の外周部には、シール部材である第１のＯリング５が嵌装される。コンデンサ１には、この第１のＯリング５を受け入れるための第１の段付穴５ｂが加工される。この段付穴５ｂを設けることにより、Ｏリングを受け入れる環状溝を省略することができる。
この第１のＯリング５により、冷媒通路２から流入する冷媒が円筒部１１７の外周部を通ってコンデンサ１の外に漏出することが防止される。
胴体１００の先端の首部１１４は、冷媒の流出用通路３に通ずる開口部に挿入される。 FIG. 2 shows a structure for assembling the joint 110 at the tip of the body 100 of the receiver dryer 10 a according to another embodiment of the present invention to the capacitor 1.
The joint part 110 has a tapered taper part 111 formed by drawing, and the taper part 111 is provided with a hole 112 for passage of refrigerant. A neck 114 is formed at the tip of the tapered portion 111.
A first stepped portion 116 and a first reduced diameter cylindrical portion 117 are formed between the body 100 and the tapered portion 111. A first O-ring 5 that is a seal member is fitted on the outer peripheral portion of the cylindrical portion 117. The capacitor 1 is processed with a first stepped hole 5b for receiving the first O-ring 5. By providing the stepped hole 5b, the annular groove for receiving the O-ring can be omitted.
The first O-ring 5 prevents the refrigerant flowing from the refrigerant passage 2 from leaking out of the capacitor 1 through the outer peripheral portion of the cylindrical portion 117.

次に、継手部１１０のテーパー部１１１と首部１１４の間には首部１１４よりは太い第２の円筒部１１５が設けてあり、首部１１４との間で第２の段付部１１３が設けてある。そして、この段付部１１３を利用して、第２のＯリング６が首部１１４の外周部にとりつけられる。
コンデンサ１側には、この第２のＯリング６を受け入れる第２の段付穴６ａが加工される。この段付穴６ａを設けることで、第２のＯリング６を受け入れるための環状溝の加工を省略することができる。 Next, a second cylindrical portion 115 thicker than the neck portion 114 is provided between the tapered portion 111 and the neck portion 114 of the joint portion 110, and a second stepped portion 113 is provided between the neck portion 114. . Then, using this stepped portion 113, the second O-ring 6 is attached to the outer peripheral portion of the neck portion 114.
A second stepped hole 6a for receiving the second O-ring 6 is machined on the capacitor 1 side. By providing this stepped hole 6a, the processing of the annular groove for receiving the second O-ring 6 can be omitted.

図１で示したように、胴体１００の反対側の端部は、取付金具７により固定されるので、段付部１１６で支持する第１のＯリング５と段付部１１３により支持する第２のＯリング６を確実に保持することができる。
なお、胴体１００をコンデンサ１側へ固定する取付金具の構成は、種々のものが採用できる。
ストレーナ１５０は、胴体１００の首部１１４の内部に挿入される。
ストレーナ１５０はフランジ１５３を有する円筒部１５２と、メッシュ部１５４を有し、樹脂を成型することにより、一体に製作される。 As shown in FIG. 1, since the opposite end of the body 100 is fixed by the mounting bracket 7, the first O-ring 5 supported by the stepped portion 116 and the second portion supported by the stepped portion 113. The O-ring 6 can be securely held.
Various configurations of the mounting bracket for fixing the body 100 to the capacitor 1 side can be adopted.
