Benefits of technology

The present patent provides an improved spray nozzle for a dishwasher that has a wider spray range and minimizes pressure loss while spreading the washing water.

Problems solved by technology

A spray nozzle in the rotary method typically sprays linear water flow via a circular nozzle port, but the rotary method has a limitation in improving the washing efficiency since the linear water flow has relatively small area of a dishware with which washing water is in direct contact.
There may be a structure to convert the linear water flow into a face-type water flow by reflecting the linear water flow, but it will cause the energy loss when water flow sprayed from the nozzle port is hit by a reflection member.
