Abstract

A ceiling type air conditioner including an indoor unit having a built-in heat exchanger and a built-in blower, and having a plurality of blowing passages for discharging, to the outside, air having passed through the heat exchanger; a discharge panel having a plurality of inlets into which air discharged through the plurality of blowing passages is delivered, an inner space at least partially communicating with the partiality of inlets, and a ring-or arc-shaped opening for discharging, into a room, air flowing into the inner space; and an air guide module mounted to the discharge panel, and moved upward and downward or rotated so as to vary airflow discharged through the opening.

First claim

The invention claimed is:

1. A ceiling mounted air conditioner, comprising:
an indoor unit having a built-in heat exchanger and a built-in blower and comprising a plurality of blowing passages configured to discharge air which passes through the heat exchanger to the outside;
a discharge panel comprising a plurality of inlets that receives the air discharged through the plurality of blowing passages, an inner space configured to at least partially communicate with the plurality of inlets, and a ring-shaped or arc-shaped opening configured to discharge, to a room, air which flows into the inner space; and
an air guide module mounted on the discharge panel and configured to be lifted/lowered or rotated to vary a flow of the air discharged to the opening, wherein the air guide module comprises:
at least one air guide liftably/lowerably or rotatably disposed at the discharge panel and configured to vary a flow of the air discharged to the opening;
a power generator configured to provide power for lifting/lowering or rotating the at least one air guide; and
a power transmitter configured to lift/lower or rotate the at least one air guide upon receiving power from the power generator, wherein the at least one air guide has an upper end provided as a plane parallel to a horizontal direction.

2. The ceiling mounted air conditioner of claim 1 , wherein the inner space of the discharge panel comprises a plurality of flow regions configured to communicate with each inlet, respectively, and allow air which flows through the inlet to flow therein, wherein a plurality of blocking regions is provided between the plurality of flow regions, and wherein the air guide module is mounted at the plurality of flow regions.

3. The ceiling mounted air conditioner of claim 2 , further comprising:
a barrier configured to divide the inner space of the discharge panel into the plurality of flow regions and the plurality of blocking regions.

4. The ceiling mounted air conditioner of claim 2 , wherein the plurality of flow regions and the plurality of blocking regions are alternately located along a circumference of the discharge panel.

5. The ceiling mounted air conditioner of claim 2 , wherein the opening comprises a plurality of first opening regions corresponding to the plurality of flow regions and a plurality of second opening regions corresponding to the plurality of blocking regions, and wherein the air guide module is mounted at the plurality of first opening regions.

6. The ceiling mounted air conditioner of claim 5 , wherein the plurality of first opening regions and the plurality of second opening regions are alternately located along a circumference of the discharge panel.

7. The ceiling mounted air conditioner of claim 1 , wherein the power generator is provided as a motor configured to provide a rotating power, and wherein the power transmitter comprises a pinion gear connected to a rotary shaft of the motor and a rack gear lifted or lowered in mesh with the pinion gear to lift or lower the at least one air guide.

8. The ceiling mounted air conditioner of claim 1 , wherein the discharge panel comprises:
a main flow path body comprising an upper body portion and an outer body portion provided on an outer side of the upper body portion, the upper body portion and the outer body portion being connected by a connecting portion; and
an inner flow path body provided on an inner side of the main flow path body to form the inner space with the main flow body.

9. The ceiling mounted air conditioner of claim 8 , wherein the air guide module is mounted at an end portion of the main flow path body or the inner flow path body.

10. The ceiling mounted air conditioner of claim 9 , wherein the at least one air guide is drawn into or out from the main flow path body or the inner flow path body.

11. The ceiling mounted air conditioner of claim 10 , wherein a surface of the air guide module which faces the inner space is configured as a flat surface to guide a horizontal air current when the air guide module is lifted, and to guide a vertical air current when the air guide module is lowered.

12. The ceiling mounted air conditioner of claim 8 , wherein the main flow path body and the inner flow path body have an inclined surface inclined downward toward the opening.

13. The ceiling mounted air conditioner of claim 8 , wherein the main flow path body and the inner flow path body have a surface which is curved so that the inner space forms a curved line toward an outer side.

14. A ceiling mounted air conditioner, comprising:
an indoor unit having a built-in heat exchanger and a built-in blower and comprising a plurality of blowing passages configured to discharge air which passes through the heat exchanger to the outside;
a discharge panel comprising a plurality of inlets that receives the air discharged through the plurality of blowing passages, an inner space configured to at least partially communicate with the plurality of inlets, and a ring-shaped or arc-shaped opening configured to discharge, to a room, air which flows into the inner space; and
an air guide module mounted on the discharge panel and configured to be lifted/lowered or rotated to vary a flow of the air discharged to the opening, wherein the discharge panel comprises:
a main flow path body comprising an upper body portion and an outer body portion provided on an outer side of the upper body portion, the upper body portion and the outer body portion being connected by a connecting portion; and
an inner flow path body provided on an inner side of the main flow path body to form the inner space with the main flow body.

15. The ceiling mounted air conditioner of claim 14 , wherein the air guide module is mounted at an end portion of the main flow path body or the inner flow path body.

16. The ceiling mounted air conditioner of claim 15 , wherein the air guide module comprises an air guide drawn into or out from the main flow path body or the inner flow path body.

17. The ceiling mounted air conditioner of claim 15 , wherein a surface of the air guide module which faces the inner space is configured as a flat surface to guide a horizontal air current when the air guide module is lifted, and to guide a vertical air current when the air guide module is lowered.

18. The ceiling mounted air conditioner of claim 14 , wherein the main flow path body and the inner flow path body have an inclined surface inclined downward toward the opening.

19. The ceiling mounted air conditioner of claim 14 , wherein the main flow path body and the inner flow path body have a surface which is curved so that the inner space forms a curved line toward an outer side.
