AI Technical Summary

Technical Problem

Existing bathroom heaters generate mechanical noise and wind noise due to motor vibration and airflow, which affects the user experience.

Method used

A noise reduction component, including a cover and a noise reduction cavity, is installed at the air inlet of the fan. The ventilation holes and sound-absorbing plates reflect and consume the wind noise generated by the airflow, thereby reducing the operating noise of the fan.

Benefits of technology

The design of the cover and noise reduction cavity effectively reduces the operating noise of the fan and improves the user experience.

Abstract

This utility model relates to a fan and heater with a noise reduction component. Existing fans have relatively high wind noise, affecting the user experience. This utility model includes a housing with an air inlet and an air outlet, a fan wheel installed inside the housing, and a motor driving the fan wheel. A noise reduction component is installed at the air inlet. The noise reduction component includes a cover, and a noise reduction cavity communicating with the air inlet is provided inside the cover. The wall of the noise reduction cavity has ventilation holes communicating with the outside space. Outside air flows through the ventilation holes and the noise reduction cavity in sequence before flowing into the air inlet. The wind noise generated by the airflow is reflected and dissipated within the noise reduction cavity to reduce wind noise. By installing a noise reduction component with a cover on the fan, air flows into the cover through the ventilation holes, ensuring that the fan can obtain airflow smoothly, and the noise reduction cavity inside the cover reflects and dissipates the wind noise generated by the airflow, thereby reducing the noise of the fan during operation and improving the user experience.
