【００１６】 また、本実施例においては、中段噴射回転ノズル２３と上段噴射回転ノズル２ ２を接続する接続パイプ５０の中間部位に給水ポンプ３０からの給水を導く上部 給水パイプ２５を連結するようにしたため、上段噴射回転ノズル２２を可能な限 り上方に配設することができて、上段噴射回転ノズル２２と中段噴射回転ノズル ２３間の上部洗浄スペースＲａを十分に確保することができ、同上部洗浄スペー スＲａに比較的大きな食器を収納できて一度に多量の食器を洗浄することができ る。[0016] In addition, in this embodiment, the middle injection rotary nozzle 23 and the upper injection rotation nozzle 2 The upper part that leads the water supply from the water supply pump 30 to the intermediate part of the connection pipe 50 that connects the water supply pump 30. Since the water supply pipe 25 is connected, the upper injection rotating nozzle 22 is connected as much as possible. The upper injection rotating nozzle 22 and the middle injection rotating nozzle The upper cleaning space Ra between 23 and 23 can be secured sufficiently. You can store relatively large dishes in the rack and wash a large amount of dishes at once. Ru.
【００１７】 更に、本実施例においては、接続パイプ５０をホルダ５１とＴ形分岐パイプ５ ２（ノズル軸受５４を含む）と連結筒５３によって構成したため、連結筒５３を 手でもって回転させることによりホルダ５１の下端部から外して、図４にて示し たように、連結筒５３による上段噴射回転ノズル２２の下方からの支持を解除す るとともに、Ｔ形分岐パイプ５２の上端とホルダ５１の下端間に形成された所定 の間隔Ｌが解放されるようにすれば、解放された所定の間隔Ｌを通して上段噴射 回転ノズル２２を単体で簡単に取り外したり取り付けたりすることができ、上段 噴射回転ノズル２２を機外に取り外して簡単に掃除することができる。[0017] Furthermore, in this embodiment, the connecting pipe 50 is connected to the holder 51 and the T-shaped branch pipe 5. 2 (including the nozzle bearing 54) and the connecting cylinder 53, the connecting cylinder 53 Remove it from the lower end of the holder 51 by rotating it by hand, as shown in FIG. As shown in FIG. At the same time, a predetermined area formed between the upper end of the T-shaped branch pipe 52 and the lower end of the holder 51 If the interval L is released, the upper stage injection The rotary nozzle 22 can be easily removed and installed as a single unit, and the The injection rotating nozzle 22 can be removed outside the machine and easily cleaned.
【００１８】 また、本実施例においては、接続パイプ５０のＴ形分岐パイプ５２において、 分岐部内部に分岐峰５２ｂが流入口５２ｃの中心線より上方に所定量変位して突 設されるとともに、下方の流出口５２ｄの開口面積が中段噴射回転ノズル２３の ノズル孔開口総面積と略等しく、また上方の流出口５２ｅの開口面積が上段噴射 回転ノズル２２のノズル孔開口総面積と略等しく、また流入口５２ｃの開口面積 が両流出口５２ｄ，５２ｅの開口面積の和に略等しくなるように設定されている ため、両流出口５２ｄ，５２ｅの内圧を略等しくすることができるとともに、途 中で拡管していないために圧力損出がなく、上段噴射回転ノズル２２と中段噴射 回転ノズル２３に略等しい圧力を加えながら各ノズル２２，２３にて必要とする 流量を適切に分けて給水することができる。また、分岐峰５２ｂに各流出口５２ ｄ，５２ｅの直径を半径とする円弧状ガイド面５２ｂ1 ，５２ｂ2 が形成されて いるため、流入口５２ｃに流れる給水を各流出口５２ｄ，５２ｅに円滑に分流さ せることができ、分岐部での圧力損出を少なくすることができる。In addition, in this embodiment, in the T-shaped branch pipe 52 of the connecting pipe 50, a branch peak 52b is provided inside the branch part and protrudes by a predetermined amount displaced above the center line of the inlet 52c, The opening area of the lower outlet 52d is approximately equal to the total nozzle opening area of the middle injection rotary nozzle 23, and the opening area of the upper outlet 52e is approximately equal to the total nozzle opening area of the upper injection rotation nozzle 22, and Since the opening area of the inflow port 52c is set to be approximately equal to the sum of the opening areas of both the outflow ports 52d and 52e, the internal pressures of both the outflow ports 52d and 52e can be made approximately equal, and the pipe is expanded in the middle. Since there is no pressure loss, water can be supplied by appropriately dividing the flow rate required by each nozzle 22 and 23 while applying approximately equal pressure to the upper stage injection rotary nozzle 22 and the middle stage injection rotary nozzle 23. . In addition, since arcuate guide surfaces 52b 1 and 52b 2 whose radius is the diameter of each outlet 52 d and 52 e are formed on the branch peak 52 b, the water supply flowing to the inlet 52 c is smoothly routed to each outlet 52 d and 52 e. The flow can be divided into two parts, and pressure loss at the branch part can be reduced.
