The first embodiment is as follows:

as shown in fig. 2 to 7, the present embodiment provides a sink dishwasher including a spray arm 1, a water inlet pipe 2, and a connection assembly 4. The connecting assembly 4 comprises a first connecting piece 41 and a second connecting piece 42, one of the first connecting piece 41 and the second connecting piece 42 is rotatably connected with the spray arm 1, the other one is connected with the water inlet pipeline 2, a first water passing channel 411 is arranged in the first connecting piece 41, and a second water passing channel 421 communicated with the first water passing channel 411 is arranged in the second connecting piece 42.

Through first connecting piece 41 and second connecting piece 42, can realize being connected of spray arm 1 and inlet channel 2, and can realize the intercommunication of the passageway in spray arm 1 and the inlet channel 2 to the water of inlet channel 2 gets into spray arm 1 that can 360 rotations through the water channel of coupling assembling 4, thereby on spraying the tableware in bowl basket 61 with water, reaches the purpose of wasing the tableware.

Wherein, the second connecting piece 42 can be fixed at different positions of the first connecting piece 41, the relative position of the rotation axis of the spray arm 1 and the central axis of the water inlet pipe 2 can be changed, the common water tank 3 which can adapt to the existing center position of the lower water cup 32 and the center line of the water tank 3 are not eccentrically overlapped, the center position of the water inlet pipe 2 and the center position of the lower water cup 32 are overlapped, the rotation axis of the spray arm 1 and the center line of the water tank 3 are overlapped, the cleaning effect of the water tank dish-washing machine is improved, the universality of the water tank dish-washing machine is improved, the water tank dish-washing machine can be transformed and upgraded by utilizing the existing common water tank in a user home, and the modification cost.

Specifically, as shown in fig. 3 to 5, the first connecting member 41 is connected to the spray arm 1, the second connecting member 42 is connected to the water inlet pipe 2, and the channel in the water inlet pipe 2, the second water passing channel 421, the first water passing channel 411 and the channel in the spray arm 1 are sequentially communicated to form a water inlet passage.

Optionally, the first port of the first water passing channel 411 is communicated with the first port of the second water passing channel 421, that is, the directly communicated port of the first water passing channel 411 and the second water passing channel 421 is the first port, and a sealing ring 43 is arranged between the first connecting piece 41 and the second connecting piece 42 to seal the joint between the first connecting piece 41 and the second connecting piece 42, so as to prevent the water leakage phenomenon at the joint.

In order to ensure the sealing effect between the first connecting member 41 and the second connecting member 42, the sealing ring 43 between the two connecting members may be an annular sealing rubber ring, or may be formed by gluing.

Wherein, one of the first port of the first water passing channel 411 and the first port of the second water passing channel 421 has a larger flow area than the other. In this way, when the second connection member 42 is fixed at a different position of the first connection member 41, the first water passing channel 411 can always be kept in communication with the second water passing channel 421.

Specifically, as shown in fig. 5 to 7, the flow area of the first port of the first water passage 411 is larger than the flow area of the first port of the second water passage 421. The first port of the first water passing channel 411 is a kidney-shaped hole, the first port of the second water passing channel 421 is a circular hole, the radius of the circular arc part of the kidney-shaped hole is equal to that of the circular hole, and the sealing ring 43 is also kidney-shaped.

The width in waist shape hole equals with the diameter of circular port, and the length in waist shape hole (length direction is perpendicular with width direction) is greater than the diameter of circular port, like this, when second connecting piece 42 is fixed in the different positions department of first connecting piece 41, the circular port can communicate with the different positions of the length direction in waist shape hole, makes first water channel 411 can remain throughout to communicate with second water channel 421.

It should be understood that the first port of the first water passing channel 411 and the first port of the second water passing channel 421 are not limited to the above, for example: the flow area of the first port of the first water passing channel 411 may be smaller than the flow area of the first port of the second water passing channel 421, wherein the first port of the first water passing channel 411 may be a circular hole or other shapes, and the first port of the second water passing channel 421 may be a kidney-shaped hole or other shapes.
