[0014] As from Fig. 1 to Fig.3, the rinse arm arrangement according to the invention comprises a rinse arm base 1, a main rinse arm 2, a first rinse arm 3, and a second rinse arm 4. The main rinse arm 2, in the upper side of which a first water outlet 5 is formed at its first end, is articulated to the rinse arm base 1. The first rinse arm 3 is articulated to the first water outlet and remains horizontally rotatable relative to the main rinse arm 2. The first water outlet 5 is continuously connected to an internal water line of the first rinse arm 3. When the water flows from the main rinse arm 2 into the first rinse arm, the first rinse arm rotates relative to the main rinse arm 2 under the water pressure and the onslaught.In addition, a second water outlet is formed in the flank at the second end of the main rinse arm 2, which is continuously connected to the internal water line of the second rinse arm 4, wherein the second rinse arm 4 is articulated to the second water outlet, or remains pivotable relative to the main rinse arm 2 under the water pressure and the onslaught, so that the spray circumferences of the rinse arms are increased in order to eliminate the spray dead angles due to untidy placement of the dishes.

[0015] A fixed gear 6 is inserted into the rinse arm base 1, while a drive element 7 and a movable gear 8 are installed on the main rinse arm 2, wherein the drive element 7 is slidably connected to the main rinse arm 2 and is further formed with an oblique groove 9 and a flat groove 10, wherein the second rinse arm 4 is provided with a first projection 11 which can engage in the oblique groove, wherein the movable gear 8 is provided with an eccentric second projection 12 which can engage in the flat groove and is connected to the main rinse arm 2 in an articulated manner, orcan engage with the fixed gear 6, wherein the drive element 7 exerts a linear reciprocating movement upon rotation of the movable gear 8 in conjunction with the interaction of the second projection 12 with the flat groove 10, while the second flush arm 4 exerts a reciprocating movement relative to the main flush arm 2 upon interaction of the first projection 11 with the oblique groove 9. When the water flows into the main flush arm 2, the main flush arm 2 rotates under the action of water pressure and the movable gear 8 is driven to rotate because the movable gear 8 engages with the fixed gear 6.
