Referring to FIGS. 1 to 6, a duct assembly 100 according to an embodiment of the present invention includes a duct 200 and an outside air discharge guide member 400.

In particular, the duct assembly 100 according to the present invention can be applied to a main body 10 of an air-conditioner. For the sake of convenience, the duct assembly 100 is shown in the main body 10 forming the outer shape of the air conditioner.

In this case, outside air heat-exchanged from a heat exchanger (not shown) provided in the main body 10 flows into the duct 200. At this time, the heat exchanger and the duct 200 are arranged close to each other in order to prevent the heat exchanged outside air from being lost as much as possible from the outside.

In addition, the heat exchanger inside the main body 10 is disposed on the upper side of the lay-out duct 200.

In addition, the duct 200 forms an outside air inlet 220 on the side of the heat exchanger provided inside the main body 10 to receive the heat-exchanged outside air. At this time, the shape and the number of the outside air inlet 220 are not limited.

The duct 200 includes a plurality of external air discharge openings 230, 240 and 250 for blowing outside air to the inside of the main body 10 through the blowing fan 210.

Particularly, the duct 200 may include a blowing fan 210 on the side of the outside air inlet 220 so as to stably suck the heat-exchanged outside air toward the outside air inlet 220. Accordingly, the blowing fan 210 is provided inside the duct 200. Of course, the blowing fan 210 may be applied in various shapes and may be operatively installed in the duct 200 in various ways.

At this time, the duct 200 is provided for maintenance and assembly of the blowing fan 210.

In detail, the duct 200 includes a first panel 202 and a second panel 204.

The first panel 202 forms an outside air inlet 220 on the upper side and operatively mounts the air blowing fan 210 to suck outside air through the outside air inlet 220. Of course, the first panel 202 can be formed in various ways. At this time, the first panel 202 is opened to one side.

The second panel 204 is coupled to the first panel 202 to cover the open side of the first panel 202. In addition, the second panel 204 forms a plurality of outside air discharge openings 230, 240 and 250.

Particularly, when the first panel 202 and the second panel 204 are assembled, an inner space 206 is formed between the first panel 202 and the second panel 204 to allow the flow of outside air. Of course, the first panel 202 and the second panel 204 may be removably assembled in various ways, and the second panel 204 may be deformed into various shapes.

In particular, the outside air discharge openings 230, 240, and 250 are disposed on the second panel 204 of the duct 200 with a height difference. This is to induce the outside air that has been heat-exchanged evenly in one ovens 12 to be blown out, or induce the outside air that is heat-exchanged evenly to each of the plurality of inside ovens 12 to be blown out.

For convenience, the outside air outlets 230, 240, and 250 are guided so as to be uniformly sprayed to one inside space 12.

More specifically, the outside air discharging ports 230, 240, and 250 include an upper outside air discharging opening 230, an intermediate outside air discharging opening 240, and a lower outside air discharging opening 250.

One or more upper air outlets 230 are formed on the upper side of the duct 200, particularly, the second panel 204. For convenience, two upper air discharge openings 230 are formed on the upper side of the second panel 204.

At least one middle outside air outlet 240 is formed at a substantially central portion in the vertical direction of the second panel 204. For the sake of convenience, it is assumed that two intermediate outside air discharge openings 240 are formed in the middle portion of the second panel 204. [

At least one lower outer air outlet 250 is formed on the lower side of the second panel 204 in the vertical direction. For the sake of convenience, it is assumed that two lower air discharge ports 250 are formed on the lower side of the second panel 204.

Of course, the upper outer air outlet 230, the middle outer air outlet 240, and the lower outer air outlet 250 may be deformed into various shapes, and the number is not limited thereto.

Particularly, the heat-exchanged outside air forms a flow locus in the circumferential direction with respect to the outside air inlet 220 by the blowing fan 210.

Thus, the heat exchanged outside air is partially discharged to the upper outside air discharge port 230, and the rest is forcedly flow in the downward direction of the duct 200.

Accordingly, the amount of the heat exchanged outside air discharged to the middle outside air outlet 240 becomes significantly smaller than the amount discharged to the upper outside air outlet 230 and the lower outside air outlet 250.

Thus, the high-temperature inside air 12 has a large cold air temperature difference in the up-and-down direction, so that the refrigerating or freezing efficiency is lowered.

In order to prevent this, the duct 200 is provided with an outside air discharge guide member 400 on the inside thereof so as to guide the discharge amount of the outside air to the outside air discharge openings 230, 240 and 250, respectively.

Particularly, the outside air discharge guide member 400 plays a role of securing a sufficient amount of outside air discharged to the outside air discharge opening 240, that is, the outside air discharge opening 240, which has a relatively small discharge amount of the outside air.

In other words, the outside air discharge guide member 400 guides a part of the outside air forcedly (dropped) from the upper side of the inside of the duct 200 to the side of the lower outside air discharge opening 250 toward the middle outside air discharge opening 240, 230, the middle outside air discharge opening 240 and the lower outside air discharge opening 250 side.

Meanwhile, the duct 200 may form the guide channel 300 to secure the blowing amount of the outside air discharged to the specific outside air discharge openings 240 and 250.

That is, the second panel 204 includes a guide channel 300 for concentrating the outside air toward the middle outside air discharge opening 240 and the lower outside air discharge opening 250 during forced flow downward to the inside of the duct 200 .

The guide channel 300 serves to guide the outside air flowing in the internal space 206 by the blowing fan 210 to blow air toward the middle outside air outlet 240 and the lower outside air outlet 250.

Therefore, the amount of outside air blown toward the middle outside air discharge port 240 and the lower outside air discharge port 250 becomes much larger than the amount of outside air discharged to the upper outside air discharge port 230.

Of course, the guide channel 300 can be deformed into various shapes.

Also, the amount of outside air blown to the middle outside air discharge opening 240 and the lower outside air discharge opening 250 can be uniform or reduced by the outside air discharge guide member 400.

As a result, the amount of the heat exchanged outdoor air flowing into the upper outer air outlet 230, the middle outer air outlet 240, and the lower outer air outlet 250 in the inner space 206 is reduced or reduced.

In other words, the guide channel 300 is disposed over a plurality of outside air discharge openings 240 and 250 having a height difference, and the outside air discharge guide member 400 serves to uniformly guide the falling outside air to the outside air discharge openings 240 and 250 .

More specifically, the outside air discharge guide member 400 includes a protrusion 410, a first inclined surface 420, a direction change guide portion 430, and a second inclined surface 440.

The protrusion 410 protrudes from the inside of the guide channel 300 to the first panel 202 side. At this time, the protruding portion 410 is provided on the guide channel 300 so as to correspond to the immediate or middle outside air outlet 240 of the middle outside air outlet 240.

The first inclined surface 420 is formed to be gradually inclined upward from the air blowing side of the protruding portion 410 to guide the outside air blown to the corresponding middle outside air outlet 240. The outside air blown downward through the guide channel 300 from the upper side of the inner space 206 is discharged and guided to the middle outside air discharge port 240 partly stably while passing through the first inclined surface 420. Of course, the inclination angle of the first inclined surface 420 is not limited.

In addition, the direction change guide portion 430 is bent so as to extend from the first inclined surface 420. That is, the direction change guide portion 430 may be a flat upper surface of the protrusion 410. At this time, the direction switching guide unit 430 guides the outside air that does not flow toward the corresponding middle outside air outlet 240 to be stably flowed toward the lower outside air outlet 250. Of course, the direction change guide unit 430 can be modified into various shapes.

The second inclined surface 440 is formed on the protrusion 410 so as to be gradually inclined downward in the direction change guide portion 430 so that the air is blown for the outside air blown toward the other outside air outlet 250, And to expand the space.

Accordingly, the outside air passing through the second inclined surface 440 is blown down due to the progressively enlarged air space, so that the outside air can be stably discharged to the lower outside air discharge opening 250 side. In addition, as the air blowing space of the outside air is expanded through the second inclined surface 440, the blowing noise of the outside air can be reduced.

In particular, the guide channel 300 may include a lower outer air outlet 250 and a lower outer air outlet 240 in order to lower the mobility (directionality) of the outside air flowing downward through the second inclined surface 440 It can be formed so as to protrude forward.

In addition, the first inclined surface 420 and the second inclined surface 440 may be curved surfaces.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Accordingly, the true scope of the present invention should be determined by the following claims.
