An air conditioner apparatus for cooling or heating indoor space through a refrigerating cycle. In the current embodiment, an air conditioner for cooling will be described as an example.

The refrigerating cycle used in the air conditioner may include a compressor for compressing refrigerant at a high temperature, high pressure state, a condenser for cooling and condensing the refrigerant compressed by the compressor by air, an expansion valve for decompressing and expanding the refrigerant condensed by the condenser, and an evaporator for causing the refrigerant expanded by the expansion valve to absorb heat from air to evaporate.

The air conditioner may include an outdoor unit disposed in outdoor space and an indoor unit disposed in indoor space. The outdoor unit may include the compressor, the condenser, the expansion valve, and an outdoor blowing fan for heat-exchanging outdoor air with refrigerant passing through the condenser. The indoor unit may include the evaporator, and an indoor blowing fan for heat-exchanging the indoor air with refrigerant passing through the evaporator.

The air conditioner may cool the indoor space by supplying low-temperature air cooled by the evaporator to the indoor space.

Hereinafter, an air conditioner according to an embodiment of the present disclosure will be described in detail with reference to the drawings.

Referring to FIGS. 1 and 2 , an air conditioner according to an embodiment of the present disclosure may include a main body 10 forming an outer appearance of the air conditioner, an evaporator 11 disposed on an inner rear side of the main body 10 to heat-exchange air inhaled into the main body 10 to cool the air, blowing fans 12 L and 12 R for inhaling and blowing air by rotating to inhale air into the main body 10 and then discharge the air to the outside of the main body 10 , and a driving motor 13 for driving the blowing fans 12 L and 12 R.

The main body 10 may include an inlet 10 a for inhaling air in the rear side, and main outlets 10 b for discharging air blown by the blowing fans 12 L and 12 R to the outside of the main body 10 in the both sides.

In the center of the front portion of the main body, an outlet panel 14 may be disposed to discharge air, at very low speed. The outlet panel 14 may include fine outlets 14 a having very small sizes. Since air delivered to the outlet panel 14 has very low speed while passing through the fine outlets 14 a , air discharged through the outlet panel 14 may not directly reach a users skin.

In the inside of the main body 10 , a first flow path 10 c for guiding air blown by the blowing fans 12 L and 12 R to the main outlet 10 b , and a second flow path 10 b for blowing air blown by the blowing fans 12 L and 12 R to the fine outlets 14 a may be provided. Two first flow paths 10 c may be provided to correspond to the two main outlets 10 b , respectively, and two second flow paths 10 d may be provided to correspond to the left and right sides of the outlet panel 14 .

Also, in the inside of the main body 10 , a pair of discharge guides 15 L and 15 R for selectively opening one of the first flow path 10 c and the second flow path 10 d so as to discharge air through one(s) of the main outlet 10 b and the fine outlets 14 a may be disposed. The discharge guides 15 L and 15 R may be movably installed in the main body 10 . The discharge guides 15 L and 15 R may move by power received from a motor (not shown) to open one of the first flow path 10 c and the second flow path 10 d and close the other one of the first flow path 10 c and the second flow path 10 d.

The blowing fans 12 L and 12 R may include a first blowing fan 12 L corresponding to the first flow path 10 c and the second flow path 10 d disposed in the left side of the main body 10 , and a second blowing fan 12 R corresponding to the first flow path 10 c and the second flow path 10 d disposed in the right side of the main body 10 . Air blown by the first blowing fan 12 L may be discharged through one of the first flow path 10 c and the second flow path 10 d provided in the left side of the main body 10 , and air blown by the second blowing fan 12 R may be discharged through one, of the first flow path 10 c and the second flow path 10 d provided in the right side of the main body 10 .

Hereinafter, an operation of the air conditioner according to the present disclosure will be described in detail with reference to the drawings.

First, when the air conditioner discharges air at normal speed, the discharge guides 15 L and 15 R may move to open the first flow paths 10 c and to close the second flow paths 10 d , as shown in FIG. 2 .

In this state, air blown by the blowing fans 12 L and 12 R may pass through the first flow path 10 c , and be discharged to indoor space through the two main outlets 10 b.

Next, when the air conditioner discharges air at very low speed, the discharge guides 15 L and 15 R may move to open the second paths 10 d and to close the first flow paths 10 c , as shown in FIG. 3 .

In this state, air blown by the blowing fans 12 L and 12 R may pass through the second flow path 10 d to be delivered to the two outlet panels 14 , and then discharged at very low speed through the fine outlets 14 a formed in the outlet panel 14 .

In addition, the air conditioner may cool left and right space in different ways.

Referring to FIG. 4 , the discharge guide 15 L provided in the left side may open the first flow path 10 c and close the second flow path 10 d , and the discharge guide 15 R provided in the right side may open the second flow path 10 d and close the first flow path 10 c.

When the discharge guides 15 L and 15 R move in this way, air of normal speed may be discharged to the left, front space of the main body 10 through the first flow path 10 c and the main outlet 10 b , and air of very low speed may be discharged to the right, front space of the main body 10 through the second flow path 10 d and the fine outlets 14 a.

On the contrary, the discharge guide 15 R provided in the right side may open the first flow path 10 c and close the second flow path 10 d , and the discharge guide 15 L provided in the left side may open the second flow path 10 d and close the first flow path 10 c , as shown in FIG. 5 .

Accordingly, air having sufficient flow speed may be discharged through the main outlet 10 b to space where no user exists so as to cool indoor space quickly, and air having very low speed may be discharged through the fine outlets 14 a toward the other space where a user exists so as to prevent cold air from directly reaching the user's skin.

In addition, one side of the indoor space may be cooled by air discharged from the main outlet 10 b , as shown in FIG. 6 , or one side of the indoor space may be cooled by air discharged from the fine outlets 14 a , as shown in FIG. 7 .

In the current embodiment, two blowing fans 12 L and 12 R may be provided to correspond to the two main outlets 10 b . This is to more efficiently discharge air through the two main outlets 10 b , but the present disclosure is not limited thereto. It is also possible that the air conditioner includes a single blowing fan to blow air and discharge it through the two main outlets.

In the current embodiment, the pair of the main outlets 10 b and the pair of discharge guides 15 L and 15 R may be provided. This is to divide indoor space to two space with respect to the main body 10 and then cool the divided space individually, but the present disclosure not limited thereto. It is also possible that the main body of the air conditioner includes a single main outlet and a single discharge guide.

Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
