AI Technical Summary

Technical Problem

Frost and dust buildup on the surface of freezer fan blades leads to reduced airflow efficiency, increased noise, increased energy consumption, and a shortened fan lifespan.

Method used

It adopts a fan-blade mounting structure that includes a diaphragm cover and a percussion device. The expansion and contraction of the diaphragm cover destroys the contact surface of the deposits, and the mechanical action of the percussion device removes the deposits.

Benefits of technology

It significantly reduces fan operating noise, improves air delivery efficiency, extends the lifespan of the fan and freezer, and ensures refrigeration performance and food preservation.

Abstract

本发明公开了一种冰柜风机扇叶安装结构，包括，机架，用于固定支撑电机结构，机架的进风端固定安装有防护网；叶轮，固定安装在电机的输出轴上，叶轮包括多个环形分布的叶片；鼓膜罩，鼓膜罩包括多个可充放气的罩膜，罩膜贴合套设于叶片上；鼓膜罩还包括固定于叶轮上的柔性圆膜板，圆膜板可启闭，圆膜板与叶轮之间形成有腔体，罩膜与腔体连通；击打器，固定于机架上，击打器用于击打圆膜板使圆膜板与叶轮之间腔体的气流流动，通过腔体内气流变化使罩膜外壁发生形变，并破坏罩膜与表面附着物的接触面。本发明显著降低了风机运行时的气流噪音，提升清理效率，大幅提升了送风（散热）效率。
