The present invention relates to an indoor unit of an air conditioner, and in particular, a diffuser in which cold air or warm air diffuses into and out of a cabinet, so that it is easy to transport and store, and cold or warm air is discharged to three sides, thereby cooling the room in three dimensions. It relates to an indoor unit of an air conditioner.

In general, an air conditioner is used to cool or heat a room or purify the air by using a refrigeration cycle of a refrigerant consisting of a compressor, a condenser, an expansion mechanism, and an evaporator to create a more comfortable indoor environment for a user. .

The separate type and the integrated type are functionally the same, but the separate type installs the indoor unit of cooling / heating function on the indoor side and the outdoor unit of heat dissipation / cooling and compression function on the outdoor side to connect the two separated devices with refrigerant piping. The one-piece type integrates the function of cooling heat dissipation compression, and is directly installed by drilling a hole in the wall of the house or hanging the device on the window.

As shown in FIG. 6, the indoor unit of a conventional air conditioner has an air inlet 1a formed at the lower front side, an air outlet 2a formed at the upper front side, and a heat exchanger 20 and a blower ( 30) is built in.

The indoor unit is equipped with a plurality of louvers 5 for protecting the inside of the air discharge port 2a.

The indoor unit of the air conditioner as described above opens the air outlet 2a after the air sucked through the air inlet 1a is cooled / heated by the heat exchanger 20 when the blower 30 is driven. Through it is discharged toward the upper front of the indoor unit.

On the other hand, when the indoor unit of the air conditioner adjusts the height of the air outlet (2a) up and down, depending on the size of the indoor space to be cooled / heated, or the arrangement structure of personnel, furniture or equipment in the space, Convection can be done efficiently.

As an example of adjusting the position of the air discharge port 2a of the indoor unit of the air conditioner as described above, there is an air conditioner having a liftable louver of Korea Patent Publication 10-0149375.

Looking at the operation of the present invention configured as described above are as follows.

First, when the air conditioner is operated and operated, the elevating means 100 raises the diffuser 70 in an upward direction of the cabinet 60 as shown in FIG. 1 so that the upper surface of the cabinet 60 is raised. In addition, the front air outlet 70a, the left side outlet 70b and the right side air outlet 70c of the diffuser 70 are opened.

That is, the controller outputs a driving control signal to the motor 102 so that the diffuser 70 can be raised, and the pinion 104 is rotated by the driving of the motor 102 to operate the rack 106. The diffuser body 72 having the rack 106 integrated thereon is raised together with the louver supporter 74, the plurality of horizontal louvers 76, and the top cover 78, so that the louver supporter 74 is formed. And the plurality of horizontal louvers 76 and the top cover 78 are positioned above the cabinet 60.

As the air conditioner rises as described above, the compressor mounted on the outdoor unit connected to the indoor unit and the refrigerant pipe and the blower 80 mounted on the indoor unit are driven.

The refrigerant is circulated between the indoor unit and the outdoor unit by the driving of the compressor, and the air around the heat exchanger 90 inside the indoor unit is cooled or heated while heat-exchanging with the refrigerant passing through the heat exchanger 90.

In addition, the outside air of the indoor unit is driven by the blower 80 and is sucked into the cabinet 60 through the left air intake port 60a and the right air intake port 60b formed on both sides of the cabinet, and the heat exchanger After being cooled or heated while passing through 90, it is blown through the blower 80 to the upper portion of the cabinet 60.

The heat-exchanged air blown to the upper part of the cabinet 60 is distributed to the front discharge port 70a, the left side discharge port 70b, and the right side discharge port 70c of the diffuser 70, and the three surfaces of the diffuser 70 are separated. It is discharged to the room through the three-dimensional cooling or heating the room.

On the other hand, when the air conditioner stops operating, the compressor of the outdoor unit and the blower of the indoor unit are driven to stop, and the lifting means 100 lowers and inserts the diffuser 70 inwardly of the cabinet 60. The front air outlet 70a, the left side air outlet 70b and the left side air outlet 70c of the diffuser 70 are sealed by the inner side of the cabinet 60.

That is, the controller outputs a reverse drive control signal to the motor 102 so that the diffuser 70 can be lowered, and the pinion 104 is driven by the reverse drive of the motor 102. The rack 106 is lowered by being rotated in the opposite direction as the lifter, and the diffuser body 72 having the rack 106 integrally includes the louver supporter 74, the plurality of horizontal louvers 76 and the top cover. Descends with 78.

In addition, when the diffuser 70 descends, the top cover 78, which is an upper surface portion of the diffuser 60, seals the upper surface of the cabinet 60.

The indoor unit of the air conditioner according to the present invention configured as described above has an advantage that the diffuser can be moved in and out through the upper surface of the cabinet, thereby reducing the overall height of the indoor unit, thereby making it easy to transport and store.

In addition, since the indoor unit of the air conditioner according to the present invention is discharged heat exchanged through the three surfaces of the diffuser, there is an advantage that can be quickly three-dimensional cooling / heating the indoor air.

In addition, the diffuser is a plurality of louvers are inserted into the cabinet when the operation of the indoor unit is stopped, there is an advantage that can prevent damage and failure of the louver.

In addition, the diffuser has an advantage that the upper surface is blocked so as to seal the upper surface of the cabinet when descending, it is possible to prevent foreign substances such as dust from entering into the cabinet during operation stop.

In addition, since the front and both sides of the diffuser are open, the front air outlet, the left side air outlet, and the right side air outlet are formed, so that the user can feel cold or warmth even if the user is located at the front, left, or right of the indoor unit. There is an advantage.
