Ultrasonic washing machine

Abstract

The invention provides an ultrasonic wave washing machine which comprises a washing trough, a roller rotationally connected with the washing trough and an ultrasonic transducer located on the outer wall of the side face of the washing trough and / or the outer wall of the bottom of the washing trough. The ultrasonic wave washing machine further comprises a vertically-placed cylindrical supporting rod located in the center of the roller and at least one protruding block located on the side wall of the supporting rod. The height of the supporting rod is matched with that of the roller. The protruding block comprises a protruding block upper surface and a protruding block lower surface. The protruding block upper surface is a hook face with the higher middle and the two lower ends. The protruding block lower surface is a hook face with the lower middle and the two higher ends. The protruding block upper surface and the protruding block lower surface converge to one point at the head of the protruding block. The joint of the protruding block upper surface and the protruding block lower surface is arranged to be a circular bead. Clothes in the roller can be scattered, the ultrasonic wave utilization rate is high, and the washing effect is good.

Description

technical field [0001] The invention relates to an ultrasonic application device, in particular to an ultrasonic washing machine. Background technique [0002] The ultrasonic washing machine is equipped with an ultrasonic high-frequency oscillator inside the washing machine, which uses the principle of ultrasonic waves to generate high-frequency shock waves, causing a large number of tiny air bubbles to be generated between the water flow and the clothes, and the air pressure shock waves generated when the bubbles burst to completely separate the dirt from the clothes Automatically complete the washing process, no or less detergent can be used, environmental pollution is improved, water resources are saved, and the washing effect is very good. Different from the traditional washing method, the ultrasonic washing machine mainly uses the "cavitation" effect of ultrasonic waves to generate huge energy to "shock" the dirt from the clothes and dissolve them into the water, and th...

Problems solved by technology

But in existing ultrasonic washing machines, because the clothes are piled up at the bottom of the washing machine, the wave sent by the ultrasonic waves weakens or changes its original direction after encountering the clothes. Or the worse the washing effect of the inner layer of clothes

[0003] The Chinese invention patent with the publication number CN103966795A discloses a new type of ultrasonic washing machine. Several ultrasonic vibration generators are arranged around the outside of the inner cylinder of the washing machine. A bubble generating device is arranged in the middle of the bottom of the inner cylinder of the washing machine. The buoyancy of the bubbles supports the clothes. However, when the air bubbles rise from the bottom to the top in the inner cylinder, the movement momentum of the air bubbles will seriously break the original path of the ultrasonic waves emitted by the ultrasonic generator. The greater the amount of air bubbles generated per unit time, the The more the ultrasonic wave is weakened, although the air bubbles disperse the clothes, but the energy of the ultrasonic wave itself is greatly weakened, and the utilization rate of ultrasonic energy is low

[0004] The Chinese invention patent with the publication number CN201372373Y discloses a grooved energy-concentrating ultrasonic washing machine. A small cylinder protrudes from the center of the bottom of the inner tub and the outer tub. Install an ultrasonic generator on the same vertical surface to gather ultrasonic energy in a small space and enhance the washing effect, but the structure of the inner and outer tubs is complex, installation and processing are difficult, and it cannot solve the ultrasonic energy utilization rate caused by the accumulation of clothes low problem
