<P>PROBLEM TO BE SOLVED: To solve the following problem that since the spraying reaction force of washing water sprayed from an spray opening of a tower nozzle 39 is produced at a position very close to the rotation center, the produced torque is small and this increases the amount of washing water sprayed only for the rotation of a washing nozzle 7 and reduces the amount of washing water sprayed on dishes. <P>SOLUTION: A valve body 23 switching multiple channels according to change in the water pressure of washing water supplied from a washing pump 6 is provided in a rotating shaft 14 and is rotated together with the washing nozzle 7. The channel of the tower nozzle 39 communicates with one of the channels of the washing nozzle 7. As a result, when water is sprayed from the tower nozzle 39 having the channel communicating with one of the channels of the washing nozzle 7, it is possible to implement the following by spraying washing water also from the washing nozzle 7: the washing nozzle 7 itself is rotated and further washing water is sprayed from the washing nozzle 7 and the tower nozzle 39. <P>COPYRIGHT: (C)2012,JPO&INPIT |
