Abstract

An air-conditioning device is provided that includes a case having an interior divided into a first area and a second area; a barrier arranged between the first area and the second area inside of the case; an indoor blowing fan arranged in the first area; an outdoor blowing fan arranged in the second area; a first thermoelectric element including a first indoor heat exchanger arranged in the first area, and a first outdoor heat exchanger arranged in the second area; a case lower-surface formed on a lower surface of the case so as to have an open upper side to collect condensed water generated from the first thermoelectric electric element; and a second thermoelectric element arranged between the first thermoelectric element and the case lower-surface.

First claim

The invention claimed is:

1. An air-conditioning device, comprising:
a case having an interior divided into a first area and a second area, provided with an indoor inlet and an indoor outlet to allow the first area and an indoor space to communicate with each other, and provided with an outdoor inlet and an outdoor outlet to allow the second area and an outdoor space to communicate with each other;
a barrier disposed between the first area and the second area inside of the case;
an indoor blowing fan disposed in the first area to form a flow of air from the indoor inlet to the indoor outlet;
an outdoor blowing fan disposed in the second area to form a flow of air from the outdoor inlet to the outdoor outlet;
a first thermoelectric element comprising a first indoor heat exchanger disposed in the first area to exchange heat with air passing through the first area, and a first outdoor heat exchanger disposed in the second area to exchange heat with air passing through the second area; and
a second thermoelectric element disposed between the first thermoelectric element and a case lower surface to heat condensed water generated from the first thermoelectric element, wherein a connection hole through which the first area and the second area communicate with each other is formed between the case lower surface and the second thermoelectric element, so that the condensed water is distributed in both the first area and the second area, wherein the second thermoelectric element is disposed at an upper side of the connection hole, wherein the second thermoelectric element comprises:
a second outdoor heat exchange surface disposed to face the second area; and
a second outdoor heat exchange fin that protrudes from the second outdoor heat exchange surface to the second area so as to heat the condensed water, and wherein the outdoor blowing fan is disposed between the first outdoor heat exchanger and the second outdoor heat exchange fin.

2. The air-conditioning device of claim 1 , wherein the second outdoor heat exchange fin is bent downward at one end thereof to be in contact with the case lower surface.

3. The air-conditioning device of claim 1 , further comprising an exhaust tube that is disposed at a lower portion of the second area of the case and communicates with the case lower surface to allow the condensed water to be discharged to an outside of the case.

4. The air-conditioning device of claim 1 , further comprising an exhaust tube in communication with the case lower surface to allow the condensed water to be discharged to an outside of the case.

5. The air-conditioning device of claim 1 , further comprising a ventilation module installed at the barrier to allow outdoor air to be introduced into the indoor space, wherein the ventilation module comprises:
a ventilation hole formed in the barrier to allow the first area and the second area to communicate with each other; and
a ventilation damper that opens and closes the ventilation hole.

6. The air-conditioning device of claim 5 , wherein the ventilation module is disposed between the outdoor inlet and the indoor outlet.

7. The air-conditioning device of claim 6 , wherein a distance from the outdoor inlet to the indoor outlet is less than a distance from the outdoor outlet to the indoor outlet.

8. The air-conditioning device of claim 5 , wherein the outdoor inlet, the ventilation module, and the indoor outlet are installed at heights corresponding to each other.

9. The air-conditioning device of claim 5 , wherein the ventilation module is disposed between the first thermoelectric element and the second thermoelectric element.

10. The air-conditioning device of claim 5 , wherein the ventilation module comprises a filter disposed between the ventilation hole and the ventilation damper.

11. The air-conditioning device of claim 1 , wherein the indoor outlet is formed at an upper portion of the case.

12. The air-conditioning device of claim 1 , further comprising:
a chassis attached to an outer surface of the case between the indoor outlet and the outdoor outlet, and configured to be inserted into a gap of a window frame.

13. The air-conditioning device of claim 12 , wherein the chassis comprises:
a lower chassis integrally formed with the case to support the case; and
an upper chassis inserted into the lower chassis to be adjustable to increase or decrease a length thereof.

14. The air-conditioning device of claim 13 , wherein the chassis comprises a blocking member attached to an upper end of an inside of the upper chassis and is corrugated to be adjustable to increase or decrease the length thereof.
