Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this process, the sizes, shapes, and the like of the constituent elements in the drawings may be exaggerated for clarity and convenience of description.

Referring to fig. 1, a ventilation apparatus according to an embodiment of the present invention may include: a heat exchange unit 10 fixed to the vertical frame 120 of the window frame 100, functioning as a passage through which the first air and the second air pass, and exchanging heat between the first air and the second air; and a main unit 20 disposed indoors, connected to the heat exchange unit 10, purifying the first air, supplying the purified first air indoors, and discharging the second air outdoors.

The first air may be outdoor air and the second air may be indoor air.

The window frame 100 is a rectangular frame shape installed in an opening of a building, and is installed to open or close the window 150 by sliding, and the window frame 100 may include: a horizontal frame 110 provided with rails so that the upper and lower surfaces of the window 150 can be slidably moved, respectively; and a vertical frame 120 connected to left and right sides of the horizontal frame 110.

As shown in fig. 3 and 4, the body unit 20 may include: a cover 24 connected to the heat exchange unit 10 and having a first air supply port 32 for supplying purified first air into the room and a second air suction port 34 for sucking second air formed in a front surface thereof; a filter 26 disposed inside the housing 24 and filtering the first air; a first air blowing unit 28 disposed inside the outer cover 24 for forcibly blowing first air; and a second air blowing unit 30 for forcibly blowing the second air.

The body unit 20 is connected to the heat exchange unit 10 at a right angle, and is disposed on an indoor wall surface close to the window frame 100, thereby preventing the window 150 from being blocked. That is, since the heat exchange unit 10 and the main body unit 20 are connected at right angles, if the heat exchange unit 10 is provided in the window frame 100, the main body unit 20 is disposed on an indoor wall surface close to the window frame, and the window 150 can be prevented from being blocked by the main body unit 20.

The heat exchange unit 10 is vertically disposed on the window frame 100, the height direction of the heat exchange unit 10 is disposed in the horizontal direction of the window frame 100, and the width direction of the heat exchange unit 10 is disposed in the vertical direction of the window frame 100.

Accordingly, the height of the heat exchange unit 10 can be minimized and the width can be increased, and the occupied area in the width direction of the window frame 100 can be reduced, whereby the visual field securing function and the sunlight transmitting function of the window can be prevented from being lowered.

The heat exchange unit 10 may be slidably installed in a fixing bracket fixed to the vertical frame 120 of the window frame 100, or may be directly fixed to the window frame 100.

In order to minimize the area of the shielding window and maintain the heat exchange area, the height of the heat exchange unit 10 is minimized and the width thereof is increased. For this reason, in the present embodiment, the height of the heat exchange unit 10 may be minimized while maintaining the heat exchange area by horizontally arranging a plurality of heat exchangers.

In the case where the heat exchange unit 10 of the present embodiment is provided in a wind-tube type, the height of the heat exchange unit is reduced by horizontally arranging a plurality of heat exchangers, and thus, the height of the entire ventilation apparatus is reduced, so that the heat exchange unit can be provided on the ceiling without being exposed to the indoor space.

As shown in fig. 5 to 8, the heat exchange unit 10 may include: a housing 12 connected to the outer cover 24 of the body unit 20, fixed to the vertical frame 120 of the window frame 100, opened in front and rear directions, to suck and discharge the first and second air; and a plurality of heat exchangers 14, 16 horizontally arranged inside the casing 12 for heat exchange of the first air and the second air.

As shown in fig. 10, the first heat exchange portion 40 may include: a first corrugated plate 40a in a corrugated form in such a manner as to form first air passages 44; and a flat plate 40b disposed so as to surround the lower surface, both side surfaces, and the upper surface of the first corrugated plate 40a, and defining a space between the first air passage 44 and the second air passage 46.

The second heat exchange portions 42 are alternately stacked with the first heat exchange portions 40, and may include second corrugated plates corrugated in such a manner as to form second air passages 46.

In the first heat exchange portion 40, the flat plate is disposed so as to surround the lower surface, both side surfaces, and the upper surface of the first corrugated plate 40a, and the first air passing through the first air passage 44 and the second air passage 46 are divided between the first air passage 44 and the second air passage 46, thereby preventing the first air passing through the first air passage 44 and the second air passing through the second air passage 46 from being mixed.

A second partition 82 may be provided at the second discharge port 62, and the second partition 82 blocks a gap between the first air passage 44 and the second discharge port 62 of the plurality of heat exchangers 14 and 16, thereby preventing the second air discharged through the second discharge port 62 from flowing into the first air passage 44.

A third partition 84 may be provided at the second suction port 64, and the third partition 84 blocks a space between the first air passage 44 and the second suction port 64 of the plurality of heat exchangers 14 and 16, thereby preventing the second air sucked through the second suction port 64 from flowing into the first air passage 44.

A fourth partition 86 may be provided at the first discharge port 66, and the fourth partition 86 blocks between the second air passage 46 of the plurality of heat exchangers 14, 16 and the first discharge port 66, thereby preventing the second air passing through the second air passage from being discharged to the first discharge port 66.

An inclined first guide plate 90 may be provided inside the front surface of the case 12, the first guide plate 90 may guide the first air sucked through the first suction port formed at the upper portion of the front surface of the case 12 to flow into the first air passages 44 of the heat exchangers 14 and 16, an inclined second guide plate 92 may be provided inside the rear surface of the case 12, and the second guide plate 92 may guide the first air passing through the first air passages 44 of the heat exchangers 14 and 16 to be discharged to the first discharge port 66 formed at the lower portion of the rear surface of the case 12.
