ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a window type air conditioner, more particularly, to the window type air conditioner having an increased heat-exchanging ability.
In general, the window type air conditioner maintains preferably an indoor temperature by exchanging a hot indoor temperature with a cold indoor temperature.
A conventional window type air conditioner, as shown in
FIG. 1
, includes a cabinet
1
having an indoor side and an outdoor side.
In the indoor side, the air conditioner comprises a front panel
2
, an air guide
8
provided on a rear side of the air guide for guiding the indoor air, a blower
6
provided on the air guide
8
for indraft and discharge of the indoor air, a motor
7
connected to the blower
8
, an indoor inlet
3
formed on one side of the front panel
2
for indrafting the hot air, an indoor heat exchanger
5
provided on a rear side of the front panel
2
for heat-exchanging between the hot air through the indoor inlet
3
and a refrigerant, an indoor outlet
4
formed on another side of the front panel
2
for discharging the air through the air guide
8
into the room, an up-down louver
9
provided on the indoor outlet
4
for up-down controlling the direction of air being discharged, a left-right louver
10
provided on the indoor outlet
4
for controlling the left-right direction of air being discharged, and a control box
11
provided on a lower side of the outlet
4
for controlling the air conditioner.
In the outdoor side, the air conditioner comprises an outdoor inlet
12
formed on outer side of the cabinet
1
, a blowing fan
14
driven by a motor
7
for discharging the outdoor air through the outdoor inlet
12
, a shroud
15
provided on an outer side of the blowing fan
14
for guiding the air through the outdoor inlet
12
, an outdoor heat exchanger
16
provided on a rear side of the blowing fan
14
for heat-exchanging between the outdoor air entering through the outdoor inlet
12
, a compressor
17
for compressing the hot refrigerant passing through the indoor heat exchanger
5
in a high temperature and high pressure atmosphere, and an outdoor outlet
13
for discharging the air through the outdoor heat exchanger
16
.
The above-mentioned air conditioner further comprises a base
18
provided on a lower side of the cabinet
1
for supporting the above elements, and a condensate water groove
19
formed on one side of the air guide
8
for discharging the condensate water in the indoor region into the outdoor region.
When the summer air conditioning mode in the control box
11
is selected by the user, the blower
6
and blowing fan
14
are turned by the driving power from the motor
7
.
Hot air from the indoor is drawn in through the indoor inlet
3
due to the turning power of the blower
6
. The drawn in hot air becomes cold air by heat exchange with the indoor heat exchanger
5
. The cold air passing through the air guide
8
is guided to the indoor outlet
4
and the cold air is discharged into the indoor with the up-down and left-right direction changing of louver
9
and louver
10
, thereby maintaining the indoor temperature.
At this time, namely, when the indoor hot air passes through the indoor heat exchanger
5
where it is heat-exchanged with the cold refrigerant conveyed in the indoor heat exchanger
5
, water condensate is generated. The condensate water is then discharged through the condensate water groove
19
formed on one side of the air guide
8
into the outdoor region.
High temperature refrigerant heat-exchanged with the indoor hot air is transferred to the compressor
17
. The refrigerant is compressed in a high temperature and pressure atmosphere and discharged in to the outdoor heat exchanger
16
. In the outdoor heat exchanger
16
, the temperature of the refrigerant is reduced and conveyed into a capillary tube (not illustrated). The inhaled refrigerant is transferred to the indoor heat exchanger
5
at a low temperature and pressure atmosphere. At this time, the indoor hot air passing through the indoor heat exchanger
5
is heat-exchanged with the cold refrigerant being moved through the indoor heat exchanger
5
.
The outdoor air passing through the outdoor heat exchanger
16
is heat-exchanged and thus the temperature of the air becomes high. The high temperature air of the outdoor is discharged into the outdoor through the outdoor outlet
13
by the turning power of the blowing fan
14
.
The condensate water being drained through the condensate water groove
19
is evaporated through the outdoor heat exchanger
16
by heat exchange, using the turning power of the blowing fan
14
.
As explained above, the outdoor air drawn in through the outdoor inlet
13
is guided to the outdoor heat exchanger
16
through the shroud
15
.
Referring to
FIG. 2
, the shroud
15
comprises an orifice
20
through which passes the outdoor air from the outdoor inlet
12
due to the turning power of the blowing fan. The shroud utilizes a plurality of locking holes
25
for inserting a plurality of screws
27
therein, an upper plate
22
hinge-connected to the shroud for preventing the shroud
15
from the heat travelling through the upper side of the shroud
15
by the outdoor heat exchanger
16
. A pair of projections
23
are formed on two upper sides of the upper plate
22
and, a pair of spigots
24
are provided for receiving the projection
23
.
On the outdoor heat exchanger
16
, an end plate
21
is provided for supporting the outdoor heat exchanger
16
and, a plurality of connecting holes
26
are provided for connecting the shroud
15
to the end plate
21
.
In the conventional window type air conditioner, since the outdoor heat exchanger
16
to be connected to the rear side of the shroud
15
is formed linearly, the heat exchanging area by the outdoor heat exchanger
16
is limited and thereby it is difficult to increase the heat exchanging ratio.
Further, when the condensate water being drained according to the condensate water groove
19
is evaporated through the outdoor heat exchanger
16
by the turning power of the blowing fan
14
, many stains on the outer surface of the air conditioner are created by the flowing of the condensate water. In addition, since the quantity of the condensate water to be dispersed to the outdoor heat exchanger
16
is small, the heat exchanging ratio is decreased and thus the efficiency of the apparatus is decreased.
On the other hand, it is hard to combine the outdoor heat exchanger
16
with the shroud
15
because it is difficult to locate correctly the outdoor heat exchanger
16
.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a window type air conditioner having the broad heat-exchanging area by modifying the shapes of the shroud and the outdoor heat exchanger.
It is another object of the present invention to better accommodate for the large quantity of the condensate water and to control the outward flow of the condensate water.
It is still another object of the present invention to combine the outdoor heat exchanger with the shroud.
In order to achieve the above-mentioned objects, the air conditioner of the present invention includes a cabinet having an indoor side and an outdoor side.
In the outdoor side, the air conditioner comprises a shroud on which an orifice going through the outdoor air from the outdoor inlet by the turning power of the blowing fan is formed, an outdoor heat exchanger for heat-exchanging of the inhaled air, and an end plate for supporting the outdoor heat exchanger, wherein one side of the outdoor heat exchanger is bent so as to provide the broad heat-exchanging area and one side of the shroud is formed with an inserting groove for inserting the outdoor heat exchanger, especially the bent side of the outdoor heat exchanger.
