Description

[0001] Ductless type ventilation apparatus [0002]

The present invention relates to a ductless type air clean ventilator, and more particularly, to a ductless type air clean ventilator which is provided as an upright case type so as to be installed on a side wall of a room without a duct, The air discharge port, the external air inlet, the external air outlet, the air purifying filter, and the separating wall, thereby making it possible to install the duct, the air supply diffuser, the exhaust diffuser, , A ventilation system for ventilating an active space extending from a floor of a room 2 m or less below the floor of a room where the people in the room are active to smoothly increase air cleaning efficiency for the active space will be.

Generally, the building is constructed so that the window is installed and the outside air flows into the room to ventilate the room air.

However, when the windows provided in the building are opened to ventilate, the cooling and heating efficiency of the building is lowered. In recent years, ventilation devices capable of forcibly ventilating the building air have been installed It is installed in a building.

A typical ventilation system is provided with a duct connecting indoor and outdoor of a building, and a blowing fan for forcibly discharging and introducing indoor and outdoor air through the duct is installed. By the blowing fan, indoor and outdoor air As shown in Fig.

Since the ventilator of this configuration does not directly ventilate through the window, it is possible to improve the efficiency of the heating and cooling of the building and to ventilate the room without a window.

However, when the temperature difference between the room and the outside is large, the ventilation device has a problem that the outdoor air directly flows into the room, and the degree of improvement of the cooling / heating efficiency of the building is insignificant.

Therefore, in order to solve the above-described problems, a technique such as that disclosed in Patent Document 1 (Korean Patent Registration No. 0690987, Feb. 27, 2007, entitled " Air Cleaning System Using Ventilation Unit ") has been disclosed.

In the air cleaning system using the conventional ventilation unit having such a configuration, outside air flowing into the room is heat-exchanged through a heat exchanger to supply air having a temperature similar to that of the room to the room, thereby preventing the cooling / heating efficiency of the building from being lowered.

The air cleaning system using the conventional ventilation unit, which is applied to the air clean ventilator of the total heat exchange type as described above, is installed on the ceiling to guide the indoor air in the ceiling portion of the room to the outside, The duct, and the equipment such as the air supply diffuser and the exhaust diffuser are necessarily connected.

In other words, since the air cleaning system using the conventional ventilation unit, which is applied to the air clean ventilator of the total heat exchange type, is required to install the duct, the supply diffuser and the exhaust diffuser, the installation cost is increased In addition, according to the method installed on the ceiling, the efficiency of air cleaning through the ventilation to the active space over the area of 2m or less from the floor of the room where the actual people are active is limited to the upper area of the lower part of the ceiling. There was a problem.

Therefore, the installation cost can be significantly reduced by installing the duct, the air supply diffuser, the exhaust diffuser, and the like without requiring the installation, and it is possible to reduce the installation cost of the indoor space It is required to research and develop an air clean ventilator which can increase the efficiency of air cleaning for the active space.

A plurality of indoor air inlets 110 are provided in the lower part of the front side of the indoor space for dividing the indoor air into the indoor air by a partition wall 115 at a ratio of 7: And an indoor air outlet 120 for guiding indoor air introduced through a lower fixed section of the indoor air inlet 110 separated by the separating wall 115 to the outside, And an outer air inlet 130 through which the outside air is introduced from the outside to the other side of the lower side of the indoor air inlet 110, A case 100 having a bypass guide for discharging indoor air to the indoor and an external air outlet 140 for guiding outdoor air introduced through the outdoor air inlet 130 to the indoor space;
The indoor air introduced through the indoor air inlet 110 and guided by bypass to the outdoor air outlet 140 is purified and guided and flows into the outdoor air outlet 140 through the outdoor air inlet 130, (151, 152) installed inside the case, which is a communication space between the indoor air inlet (110) and the outdoor air outlet (140), so that the outdoor air guided to the indoor air inlet (110) ; And
And a control box 170 installed at an upper portion of the case 100 and controlling an inflow amount to the outside air introduced through the outside air inlet 130,
The partition wall 115 installed in the case 100 to divide the indoor air inlet 110 into the indoor air inlet 110 divides the indoor air inlet 110 into a ratio of 7: The upper part of the indoor air inlet 110 communicates with the upper part of the indoor space divided by the partition wall 115 and the lower part of the indoor air inlets 110 at a distance from the one end of the indoor air inlet 110, The through hole 116 is formed through,
The air is introduced from one end of the through hole 116 to the inside of the through hole 116 and flows through the upper portion of the indoor air inlet 110 divided and introduced by the dividing wall 115, And the indoor air to be guided to the indoor air outlet 120 through the lower section of the indoor air inlet 110 and to be guided through the indoor air outlet 120, Further comprising an indoor air increasing and guiding unit (190)
The control box 170 controls the operation based on the degree of contamination of the indoor air so as to selectively guide and increase the speed of bypass guide and discharge guidance to the indoor air speed increase guide unit 190 No duct type air clean ventilation system. The method according to claim 6,
The indoor air accelerating guide unit 190 includes a pair of folding cylinders 191, one end of which is hinged to each outer surface of the through hole 116,
A folding rod 193 provided at each of opposite ends of a pair of the folding cylinders 191 so as to be able to project and retract for a predetermined length,
A fixing pad 195 connected to both ends of one end of the folding rod 193 by a hinge structure and provided with a flexible material so that both ends of the folding rod 193 can be folded with respect to the center in the longitudinal direction,
A guide groove 197a is formed on the other surface of the fixing pad 195 so as to have a constant width at the center in the width direction and to extend over the entire length in the longitudinal direction. The guide groove 197a is inclined downward And is provided with a soft material corresponding to the fixing pad 195. The folding rod 193 of the pair of folding cylinders 191 is selectively turned to the extended state based on the center through the projecting and retracting operation of the folding rod 193, Indoor air introduced through the upper portion of the indoor air inlet 110 divided by the partition wall 115 and bypassed to the exterior air outlet 140, And selectively guiding the bypass guide and discharge guide air to the indoor air introduced through the lower fixed section and discharged to the indoor air outlet 120 side Non-ducted air cleaning ventilator to the characteristic that a guide pad 197 to.
