Description

Ceiling type air conditioner

The present invention relates to a ceiling-type air conditioner, and more specifically, to a ceiling-type air conditioner capable of varying the airflow of air discharged to the outside.

An air conditioner is a device that creates a more comfortable indoor environment for users.

An air conditioner can cool or heat a room using a refrigeration cycle device having a compressor, condenser, expansion device, and evaporator through which refrigerant circulates.

Air conditioners can be classified into stand-type air conditioners, wall-mounted air conditioners, and ceiling-type air conditioners depending on their installation location.

Ceiling air conditioners are installed on the ceiling and can discharge cold or warm air into the room.

An air outlet through which air is discharged may be formed in the ceiling-type air conditioner. The air discharge port may be formed through the discharge panel in a vertical direction, and the air inside the ceiling-type air conditioner may be discharged in a downward direction through the air discharge port of the discharge panel.

The ceiling-type air conditioner may include a wind direction control member that is rotatably disposed at the air outlet to control the wind direction of air passing through the air outlet.

The wind direction control member can be rotated while positioned within the air outlet, and can block the air outlet or adjust the up and down wind direction of the air passing through the air outlet.

The wind direction control member can determine the airflow of air discharged from the ceiling air conditioner depending on its rotation angle.

First, when the lifting mechanism 120 raises the outer air guide 100 as shown in FIG. 15, the lower end 103 of the outer air guide 100 is aligned with the lower end 54C of the outer guide 54. It can be raised to a tangent height.

In this case, the air guided to the outer curved surface 55 of the outer guide 54 may be guided to the deco cover 90 along the lower end 103 of the outer air guide 100.

To explain in more detail, some of the air passing through the connection passage 26 may flow attached to the outer curved surface 55 of the outer guide 54 due to the Coanda Effect.

The air flowing along the outer curved surface 55 of the outer guide 54 passes over the bottom 103 of the outer air guide 100 while maintaining the Coanda effect along the bottom 103 of the outer air guide 100. and can flow to the bottom of the decor cover 90.

In this case, the air passing through the outlet 25 is guided along the bottom 103 of the outer air guide 100 and the bottom of the decor cover 90, and can be discharged as a nearly horizontal airflow, to the outlet 25. The discharged air can be dispersed and spread widely throughout the room.

<Airflow when lowering the air guide>

Meanwhile, when the lifting mechanism 110 lowers the outer air guide 100 as shown in FIG. 16, a part of the outer air guide 100 including its lower end 103 is lowered below the slit 57. It may be, and in this case, the outer air guide 100 may be disposed to protrude downward between the outer guide 54 and the decor cover 90.

When the outer air guide 100 is lowered as described above, the inner guide surface 101 of the lower portion of the outer air guide 100 may face the inner curved surface 65 of the inner guide 64 in the horizontal direction.

When the outer air guide 100 is lowered, the stopper 105 may be seated on the discharge panel 2, especially the mounting portion 56, and at this time, the lower end 103 and the air hole ( 104) may face the exit 25 in a horizontal direction.

Air passing through the outlet 25 may flow toward the inner guide surface 101 of the outer air guide 100.

Air flowing toward the inner guide surface 101 after passing through the outlet 25 may flow along the inner guide surface 101.

<Air flow inside and outside the outer air guide>

Some of the air flowing through the inner guide surface 101 may flow into the air hole 104 and pass through the air hole 104, and the air passing through the air hole 104 may exit through the outer surface 105. It may flow out and around the outer surface 105. As described above, the air passing through the air hole 104 can flow to the bottom of the outer surface 105 and the decor cover 90, and dew does not form on the bottom of the outer surface 105 and the decor cover 90. You can do it.

Meanwhile, among the air that is guided to the inner guide surface 101 after passing through the outlet 25, the air that does not flow into the air hole 104 is guided along the inner guide surface 101 of the air guide 100. The flow direction may bend downward. In particular, the air flowing along the outer curved surface 55 of the outer guide 54 may change its flow direction to the downward direction after hitting the inner guide surface 101 of the outer air guide 100.

That is, the air discharged through the outlet 25 may be guided to the inner guide surface 101 and discharged into a main air stream that is close to vertical, and a portion of the air may pass through the air hole 104 and be guided to be discharged into a sub air stream that is close to horizontal. It can be.

The main airflow guided by the inner guide surface 101 and flowing in a downward direction may pass around the lower end 67 of the inner curved surface 65 and be discharged concentrated in a downward direction.

<Relationship between air guide height and airflow>

In this embodiment, the higher the height of the outer air guide 100, the closer to horizontal airflow can be formed, and the lower the height of the outer air guide 100, the closer to vertical airflow can be formed.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention.
