AI Technical Summary

⚠Technical Problem

Traditional dishwasher spray arm structures have limitations in water spray range and cleaning blind spots, making it difficult to achieve all-around cleaning.

⚗Method used

Design a rotatable jet component, combined with an inclined jet channel, so that the water flow generates force on the inclined inner wall of the jet channel, driving the jet component to rotate and forming a spiral diffusion water flow. The jet pattern is dynamically distributed in three-dimensional space. With the help of bearing support components and sealing structures, the stable rotation of the jet component is ensured.

🎯Benefits of technology

It achieves all-round, no-dead-angle cleaning water curtain, increases the water flow coverage, improves the cleaning effect and the reliability and durability of the spray arm structure, and reduces maintenance costs.

Abstract

This utility model relates to the technical field of dishwasher accessories, proposing a dishwasher spray arm structure, including an arm body with a liquid inlet channel, and a rotatable spray element on the arm body. The spray element has an inclined spray channel that connects to the liquid inlet channel. Water flows into the spray channel through the liquid inlet channel, and the water flow acts on the inclined inner wall of the spray channel, driving the spray element to rotate, so that the water flow through the spray channel is sprayed in a spiral diffusion pattern to form a dynamic cleaning water curtain distributed in three-dimensional space. By making the spray element a rotatable structure, combined with the inclined spray channel, the limitations of traditional spray arm structures, such as limited water flow spray range and the existence of cleaning dead angles, are overcome. When the dishwasher is working, after the water flow enters the liquid inlet channel, the inclined inner wall of the spray channel generates a force that causes the spray element to rotate automatically. The spiral diffusion water flow spraying method allows the water flow to be dynamically distributed in three-dimensional space, forming an all-round, dead-angle-free cleaning water curtain.
