The present invention relates to a two-in-one ultra-slim air conditioner, and more particularly, to a two-in-one ultra-slim air conditioner that increases the cooling efficiency and increases energy efficiency while making the indoor unit ultra thin.

In general, an air conditioner is a type of air conditioner for cooling and circulating and purifying air for the purpose of air conditioning in a room.

Such an air conditioner can be divided into an integral type in which a component constituting a cooling cycle is provided in one unit and a separate type in which two units are separately provided. It can be divided into a wall type and a stand type for installing the indoor unit on the floor, and a wall type for installing the indoor unit on the wall.

The stand type air conditioner is a separate molar type mounted on the floor of the room to cool the indoor space, and is a kind of air conditioner that is widely used recently.

The separate air conditioner liquefies the refrigerant gas compressed in the compressor by heat exchange with outdoor air in a condenser (outdoor heat exchanger), and then heat-exchanges the refrigerant passing through the expansion valve with indoor air in an evaporator (indoor heat exchanger). The room is cooled by using the heat of vaporization.

Hereinafter, the indoor unit structure of the separate type air conditioner will be described with reference to FIGS. 1 to 3 as follows.

The indoor unit 10 of the separate type air conditioner includes a main body 11 having an inlet 12 at a lower front face thereof and an outlet 13 provided at an upper front face thereof, and an inclined obliquely installed at an upper upper side of the main body 11. It is composed of an evaporator (14) for cooling the blower (blower, 20) provided in the lower side of the evaporator (14) forcibly sucked indoor air and discharged to the evaporator (14) side.

The blower 20 generally uses a sirocco fan, a floor fan, a turbo fan, and the like, and various types of the indoor unit 10 are used or installed. Depending on the type, it is selected and used.

Among them, the overall configuration of the sirocco fan is briefly described as follows: a motor 22 installed on a bracket attached to the inside of the indoor unit main body 11, a blowing fan 24 mounted on a motor rotating shaft to suck indoor air, and a circular shape. A bell mouth (28) is installed in the air suction hole and the discharge duct of the housing 26 and the air suction hole of the housing 26 to induce the suction of air and to block the noise caused by the intake airflow. )

The air inlet 28a of the bell mouse 28 has a streamlined structure that is bent inwardly to guide the air introduced into the housing 26 to the inside of the blower fan 24 stably.

The blower 20 is located at the rear of the suction port 12 for smooth suction of the indoor air.

The indoor unit 10 of the separate type air conditioner configured as described above is driven while power is applied to the blower 20 due to the forced operation by the user or the indoor air is below the set temperature.

As the blower fan 24 rotates in the blower 20, indoor air is introduced through the suction port 12, sucked into the air suction hole of the blower fan 24, and discharged to the evaporator 14 through the discharge duct.

At this time, the indoor air is cooled by the endothermic action of the refrigerant while passing through the evaporator 14, and then discharged into the room through the discharge port 13 to cool the room.

However, in using the indoor unit 10 of such a separate air conditioner, the following problems have been raised.

The indoor unit 10 of the separate type air conditioner lowers the temperature of the room because the cooled air is discharged mainly through the one discharge port 13 located above the main body 11, and only the upper part is cooled. There was a limit.

As a result, since the air in the room is cooled through one discharge port 13 depending on the blower 20, there is a problem in that the temperature of the room cannot be cooled rapidly.

In addition, since the indoor unit 10 of the separate type air conditioner having such a configuration includes a dust removing filter and an electrostatic precipitator installed in the inlet 12 mounted on the front lower portion, the air flow path is narrow, and in recent years, Accordingly, since the distance between the housing 26 and the suction port 12 of the blower 20 is narrowed, there arises a problem that the flow path resistance increases when air is sucked.

In addition, to generate the same amount of air due to this, the number of revolutions of the blower 20 must be increased. In the current blower 20 structure, the noise increases due to the increase of the number of revolutions of the blower fan 24, thereby reducing quietness. There is a problem.

In addition, this flow path resistance has a problem of generating an increase in power consumption as well as noise.

This problem occurs more recently in the three-sided suction air conditioner package air conditioner, the indoor air sucked through the inlet 12 located in the corner between the front and both sides of the main body 11 receives a considerable flow resistance By being sucked in the axial direction of the blower 20, the power consumption is inevitably increased at the same amount of air and significant noise is generated.

 In addition, the blower 20 used in the indoor unit 10 of the separate air conditioner has a limit in reducing the overall width of the system.

That is, the blower 20 should be provided with a rotary shaft of the blower fan 24 along the width direction of the main body 11 and a motor 22 at one end of the rotary shaft in view of the flow path structure.

Therefore, in the indoor unit 10 of the conventional separate air conditioner, the width of the blower fan 24 and the size of the motor 22 have to be determined.

However, in order to obtain a certain amount of air, the length of the blower fan 24 must be secured for a predetermined length or more, and thus, it is difficult to finally slim the main body 11.

Therefore, the present invention was created to solve the above problems, it is possible to slim the indoor unit installed in the room, the two-stage output of the indoor unit is possible to provide a two-in-one ultra-slim air conditioner with increased cooling efficiency There is this.

The present invention for achieving the above object is a first suction port for sucking the indoor air, and the first air intake to the indoor suction sucked through the first heat exchanger after the heat exchanged in the first heat exchanger 1 main body; A second suction port coupled to an upper surface of the first body to suck indoor air, and cold air heat-exchanged in the indoor air sucked into the second suction port or the first heat exchanger of the first body in the second heat exchanger; A second body configured to be heat-exchanged and discharged into the room through a second discharge port; And a base installed between the bottom and bottom surfaces of the first body to support the first body and the second body.

And a damper disposed between the upper surface of the first body and the bottom surface of the second body to control a portion of the cold air heat-exchanged in the first heat exchanger of the first body to flow into the second body. do.

In addition, the base is characterized in that the height adjustment support member is installed in the lower portion of the base to be in close contact with the ground.
