Description

Window-mounted hybrid multi-function air clean and ventilation system having anti-sag function

The present invention relates to a window-mounted hybrid air cleaning ventilation system having a sagging prevention function, and in particular, the present invention is installed on the upper part of the windows of various buildings such as classrooms, offices, and warehouses of schools to discharge polluted internal air to the outside and fresh outside air. Introduced into the room, clean indoor air by fine dust filter, temperature control function by recovering waste heat during ventilation, and filter replacement function by simple operation.In particular, it prevents sagging of the middle part of the window frame caused by installation on the upper part of the window. The present invention relates to a window-mounted hybrid air cleaning ventilation system having a function of solving a problem in which the window frame is damaged and the window cannot be opened and closed, and prevents fine metal particles contained in outside air from entering the room.

Recently, as the importance of the indoor environment has emerged, various technologies for indoor air cleaning have been developed.

In general, a floor-type air purifier placed on the floor is mainly used to purify or filter indoor air. Such a floor-type air purifier purifies the surrounding air of a floor-type air purifier, but it takes a long time to purify the air as a whole. In the case of a floor-type air purifier, there is a technical limitation in that the concentration of carbon dioxide or the like is not improved because ventilation is not performed.

Recently, a technology for installing an air purifier on a window to purify or ventilate indoor air is being developed, and the air purifier mounted on the window is Korean Patent Publication No. 10-2019-0064700, a window-mounted air purifier and air purifier. The method (release date: released on June 11, 2019) is representative.

The window-mounted air cleaning device and air cleaning method are mounted on a window to purify and ventilate air, but it is difficult to utilize waste heat using the temperature difference between indoors and outdoors, and it is a very inconvenient structure to replace filters. There is a technical limitation in that it cannot implement various functions because it does not include a purification function that bypasses or purifies some air.

In addition, Korean Patent Publication No. 10-1555212, automatic ventilation system, (registration date: September 17, 2015) has been disclosed, which improves energy efficiency by performing total heat exchange and has natural ventilation and air cleaning functions.

In the case of the automatic ventilation device, as shown in Fig. 13, the automatic ventilation device 10 is disposed on the upper part of the window frame, and the automatic ventilation device is formed in a long rectangular parallelepiped shape.

However, when the automatic ventilation device is formed in such a long rectangular parallelepiped shape, a large moment is applied to the middle portion of the window frame, and as a result, the middle portion of the window frame is pressed by the automatic ventilation device to cause sagging on the window frame.

When the window frame is pressed and sagging of the window frame occurs, the window frame is not only damaged, but also opening or closing of the window becomes difficult.

The automatic ventilation device does not include a technology for solving the problem that the window frame is depressed and sagging occurs.

On the other hand, Japanese Patent Laid-Open Publication No. 2000-146250, Ventilator, (Publication date: May 06, 2000) discloses a ventilator including a total heat exchanger, and the ventilator has a problem in that the window frame is pressed and the window frame sags It does not contain technology to solve the problem.

Republic of Korea Patent Publication No. 10-2018-0054011, heat exchange ventilation system, (published on May 24, 2018) describes a heat exchange ventilation system equipped with a filtering module and a heat exchanger, but the heat exchange ventilation system includes a window frame. It does not contain a technique for solving the problem that the window frame is depressed by being pressed.

In addition, Korean Registered Patent Publication No. 10-0564445, Ventilation System, (Registration Date: March 20, 2006) discloses a ventilation system capable of removing fine dust and odors, but the ventilation system presses the window frame and sags the window frame. It does not contain technology to solve the problem that occurs.

Republic of Korea Patent Publication No. 10-0650164, waste heat recovery ventilator, (registration date: November 20, 2006) discloses a ventilator that recovers and uses waste heat, but the waste heat recovery ventilation system It does not contain a technology for solving the problem that the window frame is depressed and sagging occurs.

That is, in the prior art described above, sagging of the window frame may occur due to its own weight when mounted on the window frame, and damage of the window frame may occur due to the sagging of the window frame or according to the shape of the window frame. It has a problem that the window is difficult to open or close.
