Description

Front panel of integrated air conditioner {Front panel of air conditioner}

The present invention relates to an integrated air conditioner, and more particularly, relates to a front panel of an integrated air conditioner, wherein the indoor unit and the outdoor unit are provided in one unit and installed in a window of a building to air condition the space inside the building.

1 is a perspective view showing an external configuration of an integrated air conditioner according to the prior art, and FIG. 2 is a perspective view showing an internal configuration of a cabinet removed from the integrated air conditioner according to the prior art.

As shown in these figures, the bottom of the air conditioner is formed of a metal base fan 1, and the cabinet 3 forms both sides and an upper surface of the air conditioner. The lower end of the cabinet 3 is mounted at both ends of the base fan 1 to form a predetermined space inside the air conditioner. The cabinet 3 is provided with an outdoor suction louver 4 at a portion located on the outdoor side of the building. The outdoor side suction louver 4 is a passage through which outdoor air is sucked into the outdoor side of the air conditioner.

The front panel 5 forms the front of the air conditioner. A suction grill 7 is installed on the front panel 5. The suction grill 7 is a passage through which air in a space for air conditioning is sucked into the interior of the air conditioner. One side of the front panel 5 is provided with a discharge grill 9 for discharging the heat exchanged air in the air conditioner into the space for air conditioning. The front panel 5 corresponding to the rear surface of the suction grill 7 is provided with a filter 11 for purifying the sucked air.

An indoor heat exchanger 13 is installed at a position corresponding to the rear surface of the filter 11 to heat exchange the air passing through the filter 11 with the refrigerant of the heat exchange cycle. The indoor heat exchanger (13) is seated in an air guide (15) installed on the base fan (1). The air guide 15 guides indoor air flow inside the air conditioner. In addition, the air guide 15 serves to partition the indoor and outdoor parts inside the air conditioner when a separate barrier is not used. Reference numeral 16 is an orifice for guiding the air passing through the indoor heat exchanger 13 to the indoor side fan 19 which will be described below.

The motor 17 is installed at the rear surface of the air guide 15, that is, at a position corresponding to the outdoor side inside the air conditioner. The motor 17 is provided with a rotating shaft in both directions, one side of the rotating shaft extends to the interior side through the air guide 15, the other side of the rotating shaft extends in the opposite direction to the rotating shaft. An indoor fan 19 is installed on the rotating shaft extending to the indoor side, and an outdoor fan 21 is installed on the other rotating shaft. These fans 19 and 21 provide the driving force for the air flow in the indoor and outdoor parts, respectively.

A shroud 23 for guiding air flow on the outdoor side of the air conditioner is installed on the base fan 1. The shroud 23 is formed with a through hole in which the outdoor fan 21 is seated, allowing air to flow from one side partitioned by the shroud 23 to the other side.

The outdoor heat exchanger 24 is installed on the rear side of the air conditioner in the space partitioned by the shroud 23. The outdoor heat exchanger 24 allows the outdoor air that enters the outdoor side of the air conditioner through the suction louver 4 and the working fluid of the heat exchange cycle to exchange heat. Reference numeral 25 is a compressor.

However, the prior art having such a configuration has the following problems.

That is, since one side of the front panel 5 is provided with a discharge grill 9 for discharging the air heat-exchanged in the air conditioner into a space for air conditioning, the air is moved forward through the discharge grill 9. Discharged.

Therefore, when the conventional air conditioner is installed at a low position of the building window, air is discharged to a relatively low point of the space for air conditioning. In general, since the cool air moves to a relatively low position, a problem occurs in that the relatively high portion of the space for air conditioning is not properly cooled.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to allow the heat exchanged air to be more efficiently supplied to the entire space for air conditioning.

To this end, when the air conditioner is driven, the indoor fan 410 is rotated in the room side, and the air in the space for air conditioning is sucked into the air conditioner through the suction grill 210 of the front panel 200.

The air sucked through the suction grill 210 is purged by the air filter 220 and heat exchanged with the working fluid of the heat exchange cycle while passing through the indoor heat exchanger 310. Air that passes through the indoor heat exchanger 310 and heats to a relatively low temperature is sucked into the indoor fan 410.

Air sucked into the indoor fan 410 and discharged again is guided by the air guides 320 and 340 and flows to the discharge guide 250. In addition, the air flowing into the discharge guide 250 is discharged into the space for air conditioning through the discharge grill 244. The discharged air circulates inside the space for air conditioning to increase the temperature, and then enters the air conditioner through the suction grill 210 again.

Next, the working fluid which receives heat from the indoor heat exchanger 310 is transferred to the outdoor heat exchanger 830 of the outdoor side to exchange heat with the air sucked from the outside to discharge the heat to the outside.

That is, when the blowing fan 820 is driven and rotated by the outdoor motor 810, outdoor air is sucked in the cabinet 600, the cover grill 660, the lower grill 150, and the through slit part. The air is sucked to the outdoor side of the air conditioner 144 and flows between the shrouds 130 and 850 and the barrier 120 of the base fan 100. The air guided between the shrouds 130 and 850 and the barrier 120 is sucked into the blowing fan 820 and flows to the outdoor heat exchanger 830.

As the air passes through the outdoor heat exchanger 830, heat is exchanged with the working fluid of the heat exchange cycle. Since the air is in the cooling mode, the air is discharged to the rear of the cabinet 600 of the air conditioner by receiving heat from the working fluid.

On the other hand, the front panel 200 is installed on the interior front end surface of the base fan 100, the suction grill 210 can be opened and closed in front of the front frame 230 forming the skeleton of the front panel 200. Is installed. In addition, the discharge frame 240 is mounted on the upper inclined portion of the front frame 230, and grill parts 242 are integrally formed at both ends of the discharge frame 240 so that air is also discharged to the upper side. do.

In addition, the lower surface of the discharge frame 240 is provided with a discharge guide 250 for guiding the flow of air discharged from the inside of the air conditioner separately to guide the air discharged from the indoor fan 410 more effectively without leakage It plays a role.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

The front panel of the integrated air conditioner according to the present invention as described in detail above is composed of a front frame, a suction grill, a discharge grill, a discharge guide, etc., thereby increasing the utility of the air discharged from the indoor fan.

That is, by separately forming the discharge guide corresponding to the shape of the discharge grill on the lower surface of the upper end of the front frame there is an advantage that the flow of air is smooth.

Further, since both sides of the discharge grille are further provided with grill parts, the air discharged from the air conditioner can be discharged from the upper side as well as the upper side, thereby maximizing the efficiency of the air conditioner as a whole.
