Accordingly, the fan module 120, heat exchange module 130, and filter units 116 and 118 can be easily mounted inside the housing 110.

As shown in FIG. 3, after the fan module 120 and the heat exchange module 130 are mounted inside the housing 110, the open end and the open end of the housing 110 are closed using the housing cover 112. The other end can be blocked.

At this time, the ventilation device 100 according to an embodiment of the present invention includes a heat exchange module 130, a fan module 120, a first filter 116 of the filter units 116 and 118, and a filter inside the housing 110. The second filter 118 of the parts 116 and 118 is mounted, and the wind direction control cover 150 is assembled to the housing 110 in that order.

The housing cover 112 is provided to be detachable from the housing 110.

For example, when replacement or repair of parts such as the fan module 120 or the heat exchange module 130 mounted on the housing 110 is required, the housing cover 112 is removed from the housing 110 and the parts are removed. After replacement and repair are completed, the housing cover 112 can be reinstalled on the housing 110. Accordingly, there is an advantage in that it is convenient to maintain and repair parts mounted inside the housing 110 for the operation of the ventilation device 100.

For reference, the ventilation device 100 according to an embodiment of the present invention is fixed between the window 10 and the wall 20 to be used semi-permanently like the window 10.

Since the ventilation device 100 is fixed between the window 10 and the wall 20, the housing 110 is also fixed while being disposed between the window 10 and the wall 20.

Various methods can be used to semi-permanently fix the ventilation device 100 or the housing 110 between the window 10 and the wall 20.

Meanwhile, the housing 110 is provided with a supply opening 115, which is a passage through which indoor air flows into the interior, and an exhaust opening 117, which is a passage through which polluted air is discharged to the outside.

For reference, the supply port 115 is provided on the indoor side, and the exhaust port 117 is provided on the outdoor side.

However, depending on the operating state of the fan module 120 according to an embodiment of the present invention, the exhaust port 117 provided on the outdoor side of the housing 110 performs the role of the air supply port 115, and the exhaust port 117 of the housing 110 The air supply port 115 provided on the indoor side may be changed to serve as the exhaust port 117.

The operating state of the fan module 120 will be described in detail below.

At this time, referring to FIG. 2, at least one filter unit 116 and 118 is provided in the housing 110.

The filter units 116 and 118 are for filtering contaminants contained in outdoor air flowing into the interior of the housing 110 through the air supply port 115 of the housing 110 or adsorbing moisture contained in the flowing outdoor air. .

These filter units 116 and 118 include a first filter 116 and a second filter 118.

The first filter 116 is provided inside the housing 110, that is, adjacent to the air supply port 115 of the housing 110, and is disposed in front of the fan module 120.

Accordingly, the first filter 116 filters fine dust or contaminants contained in outdoor air introduced through the air supply opening 115 of the housing 110 by the fan module 120. For this purpose, the first filter 116 is preferably provided as a filter for fine dust, but is not necessarily limited thereto.

In addition, the second filter 118 is provided inside the housing 110, that is, adjacent to the air supply port 115 of the housing 110, and is provided in the first filter 116 located in front of the fan module 120. It is located in the front.

The second filter 118 adsorbs moisture contained in outdoor air introduced through the air supply port 115 of the housing 110 by the fan module 120, thereby lowering the humidity of the air supplied indoors.

For example, when it rains or snows, the outdoor humidity inevitably increases.

If the humidity of the outdoor air flowing in from outdoors is not controlled and is directly introduced indoors through the ventilation device 100, the indoor humidity will inevitably rise to the same level as the outdoor humidity.

Accordingly, the second filter 118 installed on the front of the housing 110 absorbs moisture from the outdoor air flowing into the housing 110, so that even if the moisture-adsorbed outdoor air flows into the room, the indoor humidity does not rise and maintains a comfortable atmosphere. The state can be maintained.

At this time, as shown in FIG. 2, the filter units 116 and 118 may not only be provided in front of the supply port 115 of the housing 110, but may also be disposed toward the exhaust port 117 of the housing 110.

As described above, depending on the operating state of the fan module 120 according to an embodiment of the present invention, the exhaust port 117 provided on the outdoor side of the housing 110 is changed to perform the role of the air supply port 115, The air supply port 115 provided on the indoor side of the housing 110 may be changed to function as the exhaust port 117.

Accordingly, although the drawings show that the filter units 116 and 118 are provided only on the supply port 115 side, it is preferable that they are also provided on the exhaust port 117 side.

Referring to Figures 2 and 3, a wind direction control cover 150 is provided in the housing 110.

Although not shown in the drawing, the wind direction control cover 150 is provided to rotate to one side or the other with respect to the housing 110 by a separately provided cover driving unit (not shown). For reference, the cover driving unit is a type of motor for generating rotational force in the wind direction control cover 150.

At this time, as the wind direction control cover 150 rotates, the open area of the opening 111 formed through one surface of the housing 110 changes.

As shown in FIGS. 2 and 3, the opening 111 is provided on the side of the housing 110, and the wind direction control cover 150 is provided on the front of the housing 110.

When the wind direction control cover 150 is rotated, the area of the opening 111 changes. At this time, outdoor air flows into the housing 110 through the opening 111, and when the wind direction control cover 150 is rotated in one direction, the area of the opening 111 is reduced. Accordingly, the amount of outdoor air flowing into the housing 110 through the opening 111 is reduced.

That is, if necessary, the amount of outdoor air flowing into the housing 110 can be adjusted by adjusting the area of the opening 111 using the wind direction control cover 150.

In addition, when operating the ventilation device 100, the direction of the wind discharged into the room through the housing 110 can be changed depending on the rotation direction of the wind direction control cover 150 with respect to the housing 110, thereby changing the indoor environment. Adjustment becomes possible.

Meanwhile, condensation on the window 10 can be prevented by rotating the wind direction control cover 150 so that the direction of air discharged from the ventilation device 100 goes toward the window 10.

For reference, although not shown in the drawing, the rotation direction of the wind direction control cover 150 may be manually manipulated by the user, or it may be connected to a separately provided control unit (not shown) and manipulated by the user through a terminal or application. However, it is not necessarily limited to this.

Referring to FIGS. 2 and 3 , the fan module 120 allows outdoor air and indoor air to flow into the housing 110 . In other words, the fan module 120 allows outdoor air to flow into the interior of the housing 110.

To this end, the fan module 120 according to an embodiment of the present invention is provided in the form of an air supply fan to make it easier to suck outdoor air and indoor air into the housing 110.

At least one fan module 120 may be provided inside the housing 110 .

For example, as shown in FIG. 2, three fan modules 120 are formed as a set, and the fan modules 120 formed as a set are connected to the air supply port 115 of the housing 110. ) and may be provided on the exhaust port 117 side, respectively.

Accordingly, a filter including a first filter 116 and a second filter 118 is provided in front of the fan module 120 provided as a set at the supply port 115 and exhaust port 117 of the housing 110. Sections 116 and 118 are positioned.

Meanwhile, the heat exchange module 130 exchanges heat with outdoor air and indoor air introduced into the housing 110 by the fan module 120 and supplies it indoors or discharges it outdoors.

The heat exchange module 130 is a commonly used heat exchanger that exchanges heat between incoming outdoor air and polluted indoor air, supplying clean air indoors, and supplying other polluted air to the indoor air. Discharge outdoors.

At this time, the temperature and humidity of the air supplied indoors can be appropriately adjusted according to the season in which the ventilation device 100 is used, so that the indoor temperature and environment can be maintained comfortably.

Meanwhile, like the fan module 120, the heat exchange module 130 may be provided in a plurality of housings 110.

For example, as shown in FIG. 2, three heat exchange modules 130 are formed as a set, and the heat exchange module 130 formed as a set is connected to the air supply port of the housing 110. It may be provided on the side of (115) and the exhaust port (117), respectively.

Meanwhile, the roles of the supply port 115 and exhaust port 117 of the housing 110 may change depending on the operating status of the fan module 120 and the heat exchange module 130.

That is, the roles of the supply port 115 and exhaust port 117 formed in the housing 110 are not fixed, and the fan module 120 or heat exchange module 130 exchanges heat by changing the wind direction in a twist type. Because it has a structure that does, the roles of the intake port 115 and the exhaust port 117 are changed.

Specifically, the fan module 120 in which three fan modules 120 are combined operates as one, and the heat exchange module 130 in which three heat exchange modules 130 are combined operates as one.

At this time, the fan module 130 and the heat exchange module 130 alternately change intake and exhaust to exchange heat with air introduced from the outside.

If the top is exhaust, the bottom becomes air supply, and if the top is air supply, the bottom becomes exhaust.

As shown in FIG. 2, the air supply port 115 provided on the indoor side of the housing 110 is provided at the top and bottom, respectively, and the exhaust port 117 provided on the outdoor side of the housing 110 is also provided at the top and bottom. Each is provided.

At this time, depending on the operating state of the fan module 120, the air supply port 115 provided on the indoor side may serve as the exhaust port 117, and the exhaust port 117 provided on the outdoor side may serve as the air supply port 115. You can also perform your role.

Meanwhile, with reference to FIG. 3, the air flow of the window ventilation device 100 according to an embodiment of the present invention will be briefly described.

Air flows in through the opening 111, passes through the second filter 118 and the first filter 116, and is supplied to the fan module 120 and the heat exchange module 130 through the air supply port 115, and the fan Indoor air and outdoor air are heat exchanged by the module 120 and the heat exchange module 130, and part of the heat exchanged air is supplied indoors, and another part of the heat exchanged air is supplied outdoors.

For reference, the number of fan modules 120 and heat exchange modules 130 may vary depending on the size and shape of the housing 110 and the space in which the ventilation device 100 is installed.

Meanwhile, the heat exchange module 130 according to an embodiment of the present invention may be provided as a sensible heat exchanger that exchanges only the temperature without exchanging the humidity of the outdoor air and indoor air introduced into the housing 110.

Specifically, the sensible heat exchanger exchanges only temperature without exchanging the humidity of outdoor air and indoor air. At this time, assuming that the heat exchanger is used in the summer, the sensible heat exchanger, like the total heat exchanger, exchanges the temperature between the outdoor air and the indoor air so that when hot and humid air from outside is supplied indoors, it has a temperature similar to that of indoor air. It ensures that air is supplied, but humidity is not involved.

Accordingly, when the heat exchange module 130 is provided as a sensible heat exchanger, humidity contained in outdoor air and indoor air remains inside the housing 110 as condensation water.

In addition, the temperature difference between indoors and outdoors is severe, so condensation occurs on the windows 10, or water (moisture) accumulates inside the ventilation device 100 due to heavy rain, typhoons, etc.

In this way, it is necessary to discharge condensation water or moisture inside the housing 110 from the housing 110 to the outside.

This is because, if moisture such as condensation water or water is not discharged from the inside of the housing 110, stagnant water is generated inside the housing 110, causing mold and the like to grow, and thus may be introduced into the room through the air. Because. In addition, there is a risk of damaging the durability of the window ventilation device 110 in the long term.

Therefore, condensation water or moisture generated inside the housing 110 must be discharged from the housing 110.

For this purpose, a moisture discharge groove 119 is formed in the housing 110.

As shown in FIG. 4, the moisture discharge groove 119 is formed in the form of an open hole at the lower end of the housing 110.

The moisture discharge groove 119 discharges condensation water generated by the heat exchange module 130, condensation generated by a temperature difference between the inside and outside, and water that flows into the housing 110 due to heavy rain or typhoons to the outside.

Meanwhile, the housing 110 is provided with a moisture removal unit 140 that opens or closes the moisture discharge groove 119.

The moisture removal unit 140 is provided in the moisture discharge groove 119 to block the moisture discharge groove 119 to insulate the window ventilation device 100, or to prevent condensation inside the housing 110 due to condensation, heavy rain, or typhoons. When it is detected that water has been generated, the water discharge groove 119 is opened to be discharged to the outside.

Referring to FIG. 4, the moisture removal unit 140 includes a damper 142, a damper driving unit 144, and a moisture detection sensor 146.

The damper 142 is provided in the moisture discharge groove 119 to open or block the moisture discharge groove 119.

The damper 142 is a blocking member for blocking the moisture discharge groove 119 and is provided in the form of a plate having a certain thickness.

For reference, the thickness of the damper 142 may be sufficient to block the moisture discharge groove 119, and since it is formed in the housing 110, it is preferably formed to have the same thickness as the housing 110.

In addition, the size of the damper 142 is preferably provided to be the same as the size of the moisture discharge groove 119 to block the moisture discharge groove 119.

Accordingly, it is possible to secure the insulation performance and airtightness performance of the ventilation device 100 by using the damper 142.

The damper driving unit 144 is connected to the damper 142 and provides driving force to rotate the damper 142.

The damper driving unit 144 uses a commonly used motor.

At this time, the type of motor used in the damper driving unit 144 may be changed to implement opening or blocking of the damper 142 in stages.

The moisture detection sensor 146 is formed at the lower end of the housing 110, that is, at a position adjacent to the moisture discharge groove 119. The moisture detection sensor 146 is electrically connected to the damper driving unit 144, and when moisture is detected, it transmits a signal to the damper driving unit 144 to open the damper 142, thereby opening the moisture discharge groove 119.

The moisture detection sensor 146 is used as a commonly used rainwater detection sensor capable of detecting moisture such as condensation water and water, but is not necessarily limited thereto.

Accordingly, when water or moisture touches the moisture detection sensor 146, it is detected and the damper driving unit 144 is activated, and the damper 142 is rotated in one direction by the damper driving unit 144 to form the moisture discharge groove 119. ) is opened to allow water or moisture to be discharged to the outside.

Meanwhile, the moisture detection sensor 146 is provided at the lower end of the housing 110 and is arranged to be spaced apart from the lower end of the housing 110.

The moisture detection sensor 146 according to an embodiment of the present invention is installed at a distance of approximately 5 mm from the lower part of the housing 110.

For reference, the distance between the moisture detection sensor 146 and the housing 110 may vary depending on the manufacturer of the window ventilation device 100 or the surrounding environment in which the window ventilation device 100 is used.

For reference, unlike what is shown in the drawing, the damper 142 and the damper driving unit 144 may not be formed as separate members, but may be formed as one member.

For example, when the damper 142 and the damper driving unit 144 are formed as one member, a wing-shaped damper is mounted on the driving motor.

That is, the damper 142 and the damper driving unit 144 are provided in a combined form, but this is not necessarily limited and the shape may be modified.

Due to the above configuration, the window ventilation device 100 according to an embodiment of the present invention filters contaminants contained in the outdoor air flowing into the interior of the housing 110 and absorbs moisture contained in the outdoor air. By providing the filter units 116 and 118, it is possible to control indoor humidity.

In addition, the window ventilation device 100 of the present invention provides a moisture removal unit 140 at the lower end of the housing 110 to immediately remove water generated from condensation, typhoons, and heavy rain inside the housing 110. It can be removed.
