Abstract

Disclosed are a ventilation apparatus and an air conditioner including the same. The air conditioner includes a main body including a heat exchanger and a blower fan blowing indoor air to pass through the heat exchanger, and a ventilation apparatus mounted on the main body to ventilate a room, the ventilation apparatus includes a case configured to accommodate a ventilation fan, a ventilation pipe including an inlet tube mounted on an outdoor air inlet of a building and an extension tube connecting a flow path of the case and the inlet tube and detachably connected to the inlet tube, and a ventilation filter installed in the ventilation pipe through a connection portion between the inlet tube and the extension tube to filter out foreign substances in air.

First claim

What is claimed is:

1. An air conditioner comprising:
a main body including a heat exchanger and a first fan to move indoor air to pass through the heat exchanger; and
a ventilation apparatus mountable on the main body to ventilate a room,
wherein the ventilation apparatus comprises:
a case configured to accommodate a second fan;
a ventilation pipe including an inlet tube having a first end mountable to an outdoor air inlet formed in a building wall and a second end opposite to the first end so as to be positioned away from the building wall while the first end is mounted to the outdoor air inlet, and an extension tube to connect to the inlet tube at the second end of the inlet tube to thereby form a flow path between the case and the inlet tube, the extension tube being detachable from the inlet tube; and
a ventilation filter installable in the ventilation pipe through a connection portion between the inlet tube and the extension tube to filter out substances in air introduced through the outdoor air inlet, the ventilation filter including a support part having an outer diameter larger than inner diameters of the inlet tube and the extension tube.

2. The air conditioner according to claim 1 , wherein
the ventilation filter comprises:
an air filtering part, in a cup shape, configured to extend along a flow direction of the air from the support part, and

the support part is configured to be supported on the connection portion between the inlet tube and the extension tube.

3. The air conditioner according to claim 2 , wherein
the air filtering part gradually decreases in diameter toward the flow direction of the air from the support part.

4. The air conditioner according to claim 3 , wherein
the extension tube is provided as a flexible tube, and
the air filtering part comprises a plurality of support ribs extending radially from an outer surface thereof to be supported on an inner surface of the extension tube.

5. The air conditioner according to claim 2 , wherein
the air filtering part has a length longer than an inner diameter of the extension tube.

6. The air conditioner according to claim 2 , further comprising:
a first connector provided at an end of the inlet tube; and
a second connector provided at an end of the extension tube to be connected to the first connector.

7. The air conditioner according to claim 6 , wherein
the support part is interposed between the first connector and the second connector.

8. The air conditioner according to claim 6 , wherein
the extension tube is provided as a flexible tube, and
the air conditioner further comprises a protective tube provided outside the extension tube to prevent deformation of the extension tube outside the air filtering part and connected to the second connector.

9. The air conditioner according to claim 2 , wherein
the air filtering part has pleats formed in a circumferential direction so that a plurality of valleys is formed in a lengthwise direction.

10. The air conditioner according to claim 2 , wherein
the ventilation filter comprises a first ventilation filter and a second ventilation filter,
the first ventilation filter is installed such that the air filtering part of the first ventilation filter is inserted into the inlet tube, and
the second ventilation filter is installed such that the air filtering part is inserted into the extension tube.

11. A ventilation apparatus comprising:
a fan configured to suck outdoor air to be supplied to a room;
a case configured to accommodate the fan and provided with a flow path to which the fan is connected;
a ventilation pipe including an inlet tube mountable to an outdoor air inlet, and an extension tube to connect the flow path and the inlet tube, the extension tube being detachable from the inlet tube; and
first and second ventilation filters installable in the ventilation pipe through a connection portion between the inlet tube and the extension tube to filter out substances in air introduced through the outdoor air inlet;
wherein the first ventilation filter includes a first air filtering part, in a cup shape, installable such that the first air filtering part is inserted into the inlet tube to extend in a direction opposite to a flow direction of the air, and
the second ventilation filter includes a second air filtering part, in a cup shape, installable such that the second air filtering part is inserted into the extension tube to extend along the flow direction of the air.

12. The ventilation apparatus according to claim 11 , wherein each of the first ventilation filter and the second ventilation filter includes:
a support part configured to be supported on the connection portion between the inlet tube and the extension tube.

13. The ventilation apparatus according to claim 12 , wherein
the air filtering part gradually decreases in diameter toward the flow direction of the air from the support part.

14. The ventilation apparatus according to claim 13 , wherein
the extension tube is provided as a flexible tube, and
the air filtering part comprises a plurality of support ribs extending radially from an outer surface thereof to be supported on an inner surface of the extension tube.

15. The ventilation apparatus according to claim 12 , further comprising:
a first connector provided at an end of the inlet tube; and
a second connector provided at an end of the extension tube to be connected to the first connector.

16. The ventilation apparatus according to claim 15 , wherein
the support part is interposed between the first connector and the second connector.

17. The ventilation apparatus according to claim 15 , wherein
the air filtering part has pleats formed in a circumferential direction so that a plurality of valleys is formed in a lengthwise direction.

18. The ventilation apparatus according to claim 15 , wherein
the extension tube is provided as a flexible tube, and
the air conditioner further comprises a protective tube provided outside the extension tube to prevent deformation of the extension tube outside the air filtering part and connected to the second connector.

19. A ventilation apparatus comprising:
a fan configured to suck outdoor air to be supplied to a room;
a case configured to accommodate the fan and provided with a flow path to which the fan is connected;
a ventilation pipe including an inlet tube mountable to an outdoor air inlet, and an extension tube to connect the flow path and the inlet tube, the extension tube being detachable through the outdoor air inlet; and
a ventilation filter including a cup-shaped air filtering part having an opening side supported in the ventilation pipe and extending in a flow direction of air in the ventilation pipe,
wherein the ventilation filter comprises a first ventilation filter and a second ventilation filter, and
the first ventilation filter is installed such that the cup-shaped air filtering part of the first ventilation filter is inserted into the inlet tube and the second ventilation filter is installed such that the cup-shaped air filtering part of the second ventilation filter is inserted into the extension tube.
