In the air conditioner provided with a stabilizer disposed close to the blower fan in the drain pan, the stabilizer is formed of a material having water absorption,
It is configured to be mounted on the drain pan.

Further, the stabilizer is sandwiched between a tongue having a bent back end of the drain pan and a guide wall provided in front of and parallel to the tongue. Further, the stabilizer is provided so as to extend so as to be flush with the tongue portion. Further, a plurality of cut portions are provided in the guide wall in a vertical direction.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the stabilizer is formed of a material having a water absorbing property, thereby absorbing dew water and preventing the dew water from scattering to the outside. Machine.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a side view of the inside of the center of an indoor unit main body, where 1 is a main body, a main body 1 is a base 2 and this base 2
The front cover 3 is detachably mounted on the front cover 3 and a front panel 4 is attached to the front cover 3 so as to be openable and closable.

An air inlet 5 for indoor air is formed at an upper portion and a front portion of the main body 1, and an air outlet 6 is formed at a lower front portion. A removable air filter 8 is provided in an air passage 7 connecting the suction port 5 and the outlet 6, an indoor heat exchanger 9 divided into a plurality of pieces and bent back and forth, and heat is exchanged by the indoor heat exchanger 9. And a blower fan 10 for sending the blown air to the blowout port 6, a drain pan 11 for receiving dew condensation water is provided below the indoor heat exchanger 9, and one side of the drain pan 11 is connected to the blower fan 10. An adjacent stabilizer 12 is provided, and the air outlet 6 has a wind direction plate for deflecting the air flow.
13 is rotatably supported.

The indoor heat exchanger 9 has an upper heat exchanger 9a having a front surface inclined toward the front of the air passage 7, and an indoor heat exchanger 9 connected to the upper portion of the upper heat exchanger 9a and inclined rearward from the air passage 7. The rear heat exchanger 9b and the lower heat exchanger 9c vertically connected to the lower part of the upper heat exchanger 9a are combined in a substantially inverted V-shape, and the upper path that performs heat exchange A two-pass refrigerant flow path of 9d and a lower pass 9e is formed, and an on-off valve 14 is provided in the upper pass 9d, and the on-off valve 14 is closed at the time of 1/2 capacity control operation, and the refrigerant is only the lower pass 9e. It is made to flow.

2 (A) and 2 (B), a tongue 15 is formed by bending a back end of a drain pan 11 which receives dew water flowing down from the indoor heat exchanger 9 and a front part of the tongue 15. A guide wall 16 provided in parallel has a configuration in which a stabilizer 12 extending and formed on the same surface as the tongue portion 15 is sandwiched. Further, the stabilizer 12 is formed of a water-absorbing material such as a resin. Also, the guide wall
A plurality of cut portions 16a are provided in the vertical direction 16 so that the dew condensation water is led out to the drain pan 11.

In the above configuration, even if dew condensation occurs on the blower fan 10 side of the stabilizer 12 during a 1/2 capacity control operation in which the refrigerant flows only through the lower path 9e in a dehumidifying operation or the like, the condensed water is removed from the stabilizer 12 Absorbs water at the guide wall
By leading the condensed water to the drain pan 11 through the cut 16a, the dew water can be prevented from scattering to the outside of the indoor unit.

[0012]

As described above, according to the present invention, since the stabilizer is formed of a material having a water absorbing property, the condensed water is absorbed by the stabilizer and discharged to the drain pan, so that the condensed water is supplied to the outside of the indoor unit. It becomes an air conditioner that can prevent scattering to the air.
