They are mainly used to wash dishes, silverware, cutlery, cups, glasses, pots, pans, and other tableware. Existing dishwashers include a shelf for placing tableware and a rotatable spray arm. The spray arm of most dishwashers is generally arranged under the shelf. When washing tableware, the spray arm is hydraulically driven to rotate 360° evenly under the water pressure generated by the circulation pump. The spray arm sprays a uniform pressure water column to form an impact force to impact the surface of the tableware, complete the erosion and shearing effect of the residue, and then cooperate with the saponification effect of chemical detergents to remove stains on the surface of the tableware;

[0003] Currently, the spraying mode of the spray arm is a rotating spraying mode that sprays evenly at 360°, and the spraying trajectory of the spray arm is circular. This conventional spray arm cannot provide targeted enhanced washing to a specific area, resulting in poor cleaning effect for dishes that require enhanced washing.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0032] In the embodiment of the utility model, by setting the deceleration member 300 to extend outside the rack 100 and extend to intersect with the rotation trajectory of the spray arm 200, the spray arm 200 can collide with the deceleration member 300 during the rotation process and decelerate the rotation. The decelerated rotating spray arm 200 can extend the spray time of a specific area, achieve targeted enhanced washing of a specific area, and thus improve the cleaning effect of the tableware that needs enhanced washing; the spray arm 200 decelerates and rotates after colliding with the deceleration member 300, and the area where the spray arm 200 decelerates is the area for enhanced washing;

[0033] The shelf 100 is in the shape of a groove, and tableware is placed in the groove of the shelf 100. The spray arm 200 is outside the groove of the shelf 100, and the deceleration member 300 extends outside the shelf 100 until it intersects with the rotation trajectory of the spray arm 200 outside the groove of the shelf 100, so that the spray arm 200 can collide with the deceleration member 300 when it reaches a certain position during the rotation process; the rotation of the spray arm 200 can be driven by a motor to rotate the spray arm 200 or by driving the spray arm 200 to rotate through the water spraying direction of the spray port on the spray arm 200.

[0034] In an embodiment of the utility model, the spray arm 200 rotates under the shelf 100 to form a circular rotation trajectory, the axis of the rotation trajectory extends vertically, the speed reducer 300 is cylindrical and can produce elastic deformation when colliding with the spray arm 200, the axis of the speed reducer 300 extends vertically, and the speed reducer 300 extends downward to intersect with the rotation trajectory of the spray arm 200.

[0037] When the deceleration member 300 contacts the spray arm 200 and collides with the spray arm 200, the spray arm 200 starts to decelerate. When the top surface of the spray arm 200 passes through the deceleration member 300, the deceleration of the spray arm 200 ends. Therefore, the area where the spray arm 200 decelerates is the area where the spray arm 200 sprays and rotates during the process from the time when the deceleration member 300 contacts the spray arm 200 and collides with the spray arm 200 to the time when the top surface of the spray arm 200 passes through the deceleration member, that is, the enhanced washing area.

The front side of the spray arm 200 in the rotation direction then moves along the guide surface 310a of the guide portion 310 from the maximum radial dimension end of the guide portion 310 to the minimum diameter dimension end of the guide portion 310, and finally to the bottom of the speed reducer 300. Specifically, it finally reaches the bottom of the guide portion of the speed reducer, and then the top surface of the spray arm 200 contacts the bottom end surface of the guide portion 310 until the top surface of the spray arm 200 passes the speed reducer 300, the deceleration of the spray arm 200 ends, and the spray arm 200 resumes its original speed and continues to rotate.
