An ultrasonic dish washing machine comprises a body, an upper cover and a control panel, wherein a working groove and a dish rack are arranged in the body; the upper cover is provided with an upper spray arm, the center of the upper spray arm is provided with a self-excitation system, the outer wall of the upper spray arm is provided with cavitation jet water outlets, and the cavitation jet water outlets are arranged around the center of the upper spray arm at equal intervals and are all inclined water outlets; the bottom surface in the work groove is provided with a lower spray arm, a water flow passage is arranged in the lower spray arm, and the tail end of the water flow passage is a water outlet. The washing machine optimizes the water outlet impact force of the self-vibration pulse cavitation jet, combines the traditional mechanical spray washing and ultrasonic all-around washing, and can form a washing mode of intermittent water spraying through a proper washing sequence and a washing period, so that the washing effect is achieved in a mode of low water consumption and no detergent environmental protection. |
