A duct structure for a drying rack

By designing an annular flow channel and an air outlet channel in the drying rack of the baby bottle washing machine, a centrifugal air channel is formed, which solves the problem that the outer surface and inner cavity of the baby bottle cannot be fully dried, and achieves simultaneous and efficient drying and increased air volume.

AI Technical Summary

Technical Problem

The drying racks of existing baby bottle washing machines cannot fully dry the outer surface of the bottles, resulting in poor drying performance.

Method used

An air duct structure including an air inlet channel and a diversion channel was designed. The diversion channel has annularly distributed air outlet holes and air outlet channels to form a centrifugal air duct. The airflow rotates along the outer wall of the container, and the inner cavity and outer surface are dried simultaneously.

Benefits of technology

It achieves simultaneous and efficient drying of the outer surface and inner cavity of the baby bottle, enhancing the drying effect, reducing air loss, increasing air volume, and improving drying efficiency.

Abstract

A drying rack duct structure includes an air inlet channel and a distribution channel. The air inlet channel connects to the distribution channel, which is annular. Several first air outlets are distributed at the top of the distribution channel, communicating with the inner cavity of the container. Several air outlet channels are annularly distributed on the outer side of the distribution channel, connecting the first air outlets and the air outlet channels respectively. The air outlet channels are positioned tangentially to the distribution channel to form a centrifugal air duct. This drying rack duct structure, by having several air outlet channels annularly distributed on the outer side of the distribution channel and positioned tangentially to the distribution channel, forms a centrifugal air duct. The centrifugal air duct causes the airflow to rotate along the outer wall of the container, which can thoroughly dry the outer surface of the container, accelerate the evaporation of moisture from the outer surface, thereby enhancing the external drying effect. Furthermore, the rotating airflow can reduce wind loss and increase air volume.
