The refrigeration cycle that makes up an air conditioner consists of a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle goes through a series of processes consisting of compression-condensation-expansion-evaporation, and after the high-temperature air exchanges heat with the low-temperature refrigerant, the low-temperature air is supplied indoors.

The compressor compresses the refrigerant gas at high temperature and pressure and discharges it, and the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid state and releases heat to the surroundings through the condensation process. The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve. The evaporator uses the latent heat of evaporation of the refrigerant to achieve a refrigeration effect by exchanging heat with the object to be cooled, and returns the low-temperature, low-pressure refrigerant gas to the compressor. Through this cycle, the air temperature in the indoor space can be adjusted.

The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that consists of a compressor and an outdoor heat exchanger. The expansion valve may be located in either the indoor or outdoor unit, and the indoor heat exchanger is located in the indoor unit of the air conditioner.

The following describes the operation of the air conditioner of the present invention.

Figures 8, 9, 10, and 11 are diagrams of the operation of an air conditioner according to an embodiment of the present invention.

Air introduced into the housing 10 from the outside exchanges heat with the heat exchanger 20. The air conditioned by the heat exchanger 20 is discharged to the outside of the housing 10 by the blower 30.

The air conditioner 1 discharges air that has passed through the heat exchanger 20 to the outside through at least one of the first discharge part 41 and the second discharge part 50. In other words, intensive air conditioning can be achieved by discharging through the first discharge part 41 as in the first mode, and air conditioning can be achieved throughout the room by discharging through the second discharge part 50 as in the second mode. You can also make it happen slowly.

The first discharge unit 41 can be opened and closed by operating the door unit 60. When the first discharge part 41 is open, heat-exchanged air is discharged through the first discharge part 41, and when the first discharge part 41 is closed, heat exchanged air is discharged through the second discharge part 50. air is discharged.

In detail, the first mode will be described.

Figures 8 and 9 are diagrams of an air conditioner operating in the first mode.

In the first mode, heat-exchanged air is discharged through the first discharge portion 41. In the first mode, the door unit 60 is positioned at the door opening position 60a, and the door blade 62 is spaced apart from the guide opening 43 to open the first discharge portion 41.

In this case, the air flowing from the blowing unit 30 flows to the first discharge unit 41 through the first discharge passage 41a formed by the guide body 46.

When the air is discharged to the outside of the housing 10 through the first discharge unit 41, it is discharged to the outside while maintaining the wind speed generated by the blower 30.

Next, the second mode will be explained.

10 and 11 are diagrams of an air conditioner operating in the second mode.

In the second mode, heat-exchanged air is discharged through the second discharge portion 50. In the second mode, the door unit 60 is positioned at the door closing position 60b, and the door blade 62 comes into contact with the guide opening 43 to close the first discharge portion 41.

In this case, the air flowing from the blower 30 passes through the guide hole 47 formed in the guide body 46 because the first discharge part 41 is blocked by the door blade 62. Through this, the air flowing from the blower 30 passes through the second discharge passage 50a and flows to the second discharge portion 50.

When the air is discharged to the outside of the housing 10 through the second discharge portion 50, the wind speed is reduced as the air passes through the plurality of discharge holes of the discharge plate 14, and the air is discharged to the outside at a low speed.

Through this configuration, users can cool or heat the room at a wind speed that feels comfortable.

In the above description, the first discharge unit 41 and the second discharge unit 50 may be referred to as a high-speed discharge unit and a low-speed discharge unit, respectively.

Next, the third mode will be explained.

The third mode is a mode in which the heat-exchanged air is distributed to the first discharge part 41 and the second discharge part 50 and discharged to the outside of the housing 10. The amount of air distribution to each discharge part can be adjusted by setting and can be adjusted by the control unit. Additionally, by applying a temperature sensor, it can be adjusted according to the surrounding environment.
