Description

Window type ventilation purifier {Ventilation and Air-cleaning Apparatus Combined to Window Frame}

The present invention relates to a ventilation purifier, and more particularly, to a window type ventilation purifier that can be used in combination with a window frame.

A ventilation device is a device for exchanging indoor/outdoor air while discharging indoor polluted air to the outdoors and supplying fresh outdoor air to the indoor space. Such a ventilation device is essential in order to maintain a pleasant indoor environment of a building.

The natural ventilation method is generally used as a ventilation device, which allows ventilation through an opening in a building due to a difference in wind pressure and temperature around the building without using separate power or energy. However, since it is difficult to secure a stable ventilation amount and create a comfortable indoor environment using only the natural ventilation method, a mechanical ventilation method in which air is forcibly moved using a mechanical device such as a ventilation fan is used in parallel.

The mechanical ventilation type ventilation device is generally installed in addition to the air conditioning equipment installed on the wall or ceiling of the room to ventilate the indoor air. However, in the case of adding to the air conditioning equipment, there is a problem in that the scale of the entire air conditioning equipment is increased, and furthermore, electricity consumption is increased in the ventilation operation mode.

In order to solve this problem, a stand-alone type ventilation device that can be installed separately from the air conditioning equipment has been proposed. As such a stand-alone type ventilation device, there is Korean Patent No. 1921206 (hereinafter, 'prior art').

Looking at the structure of the ventilation purifier of the prior art, the main body casing, the exhaust port for exhausting the bet to the outside, the intake port for introducing the outside air into the room, the air supply port for supplying the purified outside air or the bet to the room, and the ventilation port for sucking the bet air into the room , filters, intake dampers, ventilation dampers, supply air dampers, exhaust dampers, emergency exhaust dampers, and blower fans.

However, in the conventional ventilation purifier, the outside air flowing in from the outside and the indoor air discharged to the outside are mixed during the ventilation process, resulting in that fresh outside air is not sufficiently introduced.

4 is an operation diagram showing the operation of the rotating intake plate and the rotating exhaust plate in the window type ventilation purifier according to the present invention.

As shown in FIG. 4 , intake air is strongly discharged to one side of the room through the gap of the rotating intake plate 161 . At this time, as the rotation angle of the rotating intake plate 161 is decreased, the intake air pressure increases, and as a result, the intake air may be discharged far/strongly to the side of the room.

On the other hand, the exhaust is, on the opposite side from the gap of the rotary intake plate 161 described above, through the gap of the rotary exhaust plate 162 through the lower front hole H31 of the front support 150 and the exhaust of the central support 110 . It is discharged to the outside through the hole H11 and the like. In this case, when the rotation angle of the rotary exhaust plate 162 is reduced, the exhaust pressure increases, and as a result, the indoor air can be rapidly and strongly discharged while drawing the indoor air farther to the side.

In this way, the window type ventilation purifier of the present invention can effectively block or minimize mixing of intake and exhaust by separating the flow of intake and exhaust while rotating the intake plate 161 and the rotation exhaust plate 162 symmetrically in opposite directions. can

In addition, the intake guide G1 and the exhaust guide G2 provided on the rear surfaces of the rotating intake plate 161 and the rotating exhaust plate 162 smoothly induce intake and exhaust flows, thereby increasing the movement speed of intake and exhaust.
