Description

Ventilating apparatus using windows and doors

The present invention relates to a natural ventilation device using a window, and relates to a natural ventilation device using a window that can be installed in the window and circulate the internal and external air.

In various buildings, the window has a function of ventilating indoor air as one of its functions. When the room is closed for a long time with the window closed, indoor air is contaminated, and this contaminated indoor air causes a lot of diseases to the human body. In particular, various dusts and microorganisms in contaminated air cause respiratory diseases and allergies, and various contaminants generated from building materials in the room, such as formaldehyde, volatile organics, and asbestos powder, can cause headaches, coughs and itching. This can lead to dizziness, fatigue, poor concentration, and even cause heart disease and cancer.

Therefore, it is necessary to prevent the accumulation of dust, microorganisms, various contaminants, etc. in the room by allowing the indoor air to be ventilated with the clean air outside. As a method of ventilating indoor air, there is a method of forcibly venting by a fan, but in the case of a house, there is a problem of generating noise, and power for driving a blower is required.
