Abstract

The invention relates to a fan cover fixing structure of air-changing system for making indoor air exchange. It is characterized by that on the lower end portion of the fan cover a fixing device for preventing said fan cover from moving along side direction. Said fixing device is formed from left side fixing portion for preventing lower end portion of said fan cover from moving toward left side direction and right side fixing portion for preventing said fan cover from moving toward right side direction. Said invention also provides the concrete structure of said fixing device.

Description

technical field [0001] The present invention relates to a ventilation system, and more specifically relates to a fan housing fixing structure of ventilation system for firmly fixing the fan housing wrapping the forced air fan. Background technique [0002] In recent years, due to issues such as energy and noise, human living spaces tend to be more and more dense. However, the air in this closed space gradually turns into carbon dioxide as time goes on, and it will be polluted, thereby hindering the breathing of living organisms. [0003] Especially in places where people often stay, such as offices or vehicles, the air should be changed at any time. In this case, a ventilator with a heat exchange method is usually used. This ventilator is capable of supplying outside air and exhausting indoor air while maintaining the temperature of the indoor air. [0004] figure 1 The middle is a schematic diagram of the appearance of the existing ventilation device, figure 2 Shown i...
