AI Technical Summary

Technical Problem

In existing dishwashers, the hose between the upper spray arm and the water cup is longer and easy to bend, resulting in a decrease in the water flow pressure and affecting the washing effect.

Method used

The upper spray arm water pipe design includes a first pipe section, an adapter and a second pipe section. The adapter is arranged on the base. The axis of the first adapter pipe section and the second adapter pipe section are at an obtuse angle. The upper spray arm water pipe is fixed to reduce the probability of bending, and reduce the water flow steering and pressure loss through obtuse angle transfer.

Benefits of technology

The water flow pressure flowing to the upper spray arm is increased, the washing effect of the tableware is enhanced, and the problem of reducing the water flow area or blocking is avoided.
