<p>PURPOSE: To improve a cleaning washing effect by providing two cross-sectional direction nozzles at both the sides of a throat. CONSTITUTION: A throat 16 is formed between a supplying port 12 and an output nozzle 28, and two cross-sectional direction nozzles 22, 24 are provided at both the sides of the throat 16. This allows forming a zero-degree jet of a high density to give high cleaning ability. Forward and backward oscillating the jet at high frequency gives the jet an angle expansion, thereby the cleaning washing effect can be improved.</p> |
