Description

ASSEMBLING TYPE VENTILATION APPARATUS FOR WINDOW FRAME

It relates to a prefabricated ventilation system for windows and doors that can be installed in different sizes between a window and a window frame, and can purify indoor air according to changes in air quality.

In general, in various buildings, windows have an important function of ventilating indoor air. If you live in a sealed indoor state for a long time without opening a window, the indoor air is polluted with form and radon, and this polluted indoor air acts as a factor inducing many diseases in the human body.

In particular, various dust and microorganisms in the polluted air cause respiratory diseases and various allergies, and various pollutants generated from indoor building materials, such as formaldehyde, volatile organic matter, asbestos powder, radon, etc., cause headaches and coughs. , itching, dizziness, fatigue, difficulty concentrating, and even cause heart disease and cancer.

Accordingly, it is necessary to prevent the accumulation of dust, microorganisms, and various contaminants in the room by allowing the indoor air to be ventilated with the clean outdoor air.

However, as air pollution worsens in recent years, outdoor air contains pollutants such as (ultra) fine dust, which are more harmful to the body than indoor air, making it difficult to open windows and ventilate.

Therefore, although it is necessary to periodically ventilate the indoor air by discharging it, there is a problem in that the indoor air purifier must be operated in a state in which the inflow of air from the outside is blocked in order to remove pollutants such as fine dust from the outside.

Claims (8)

a guard frame installed between the window and the window frame and having an installation space;
an air filter module installed in a stacked state in the installation space, a first fixing part fixed to the guard frame is formed on one side and a second fixing part fixed to the guard frame is formed on the other side; and
a ventilation module installed between the air filter module and the guard frame in the installation space;
including,
The guard frame is
a frame body installed between the window and the window frame and having an opening;
an insertion protrusion protruding from one side of the frame body and inserted into the window frame; and
a fixing protrusion that protrudes from the other side of the frame body and is inserted and fixed into the edge groove of the window;
including,
A plurality of fixing grooves are formed at an edge of the opening of the frame body to which the first fixing part and the second fixing part are fixed,
A height adjustment unit for varying the height installed on the window frame is detachably installed on the frame body,
The height adjustment unit,
a lower adjustment part detachably fixed to the lower part of the frame body and supported on the lower part of the window frame;
an upper adjustment part detachably fixed to the upper part of the frame body and supported on the upper part of the window frame;
A prefabricated ventilation system for windows, including.
delete The method of claim 1,
A prefab ventilation device for windows and doors, in which a fitting protrusion to which the lower control unit and the upper control unit are fitted and fixed protrudes from the frame body.
4. The method of claim 3,
The air filter module,
a module housing in which a fitting protrusion which is fitted and fixed to the fixing groove formed in the frame body on the outer surface protrudes; and
a plurality of air filters installed inside the module housing;
including,
A prefabricated ventilation device for windows and doors, in which a grill part covering a state in which the air filter is installed is installed in the module housing.
5. The method of claim 4,
The ventilation module is
a ventilation housing having a fitting protrusion fixed to the fixing groove formed in the frame body protruding from the outer surface and installed between the air filter module and the guard frame;
a ventilation frame installed inside the ventilation housing;
a ventilation fan installed in the ventilation frame;
a fine dust measuring unit which is slidably installed inside the ventilation frame and includes an air quality sensor for checking a pollution state of indoor air; and
a control unit that transmits a sensing signal of the air quality sensor to check the indoor pollution state from a remote location and operates the ventilation frame when the pollution state exceeds a set range;
A prefabricated ventilation system for windows, including.
6. The method of claim 5,
a temperature sensor that is installed in the ventilation frame and senses the temperature of the indoor air to sense whether the temperature is higher than a set temperature; and
a communication module that notifies a remote location when it is confirmed that a fire has occurred according to the sensing signal of the temperature sensor;
Further comprising, a prefabricated ventilation device for windows.
6. The method of claim 5,
A grill part is installed in the ventilation housing,
A sterilization module for sterilizing air in the ventilation process is installed in the grill unit, a prefabricated ventilation device for windows and doors.
6. The method of claim 5,
Further comprising a differential pressure sensor installed on the ventilation frame to sense the pressure difference between the outdoor and indoor,
The differential pressure sensor, when the pressure difference is sensed as a pressure that requires sound pressure management, controls the driving speed of the ventilation fan to adjust and control the flow of ventilated air, a prefab ventilation device for windows and doors.
