Further, an air filter 38 and a stabilizer 39 are arranged in the indoor circulation chamber 36. The air filter 38 is installed between the suction grill 40 formed on the front panel 18 and the indoor heat exchanger 11. The stabilizer 39 is installed above the indoor heat exchanger 11 and bulges toward the cross flow fan 12. By this stabilizer 39, the air in the indoor circulation chamber 36 is satisfactorily sucked into the cross flow fan 12 and is satisfactorily discharged from the cross flow fan 12. On the front panel 18, a blowout grill 43 that guides the discharged air into the interior of the building is formed above the suction grill 40.

By the rotation of the cross flow fan 12, as shown by the arrow B in FIG. 3, the air in the room of the building is taken in from the suction grill 40 into the indoor circulation chamber 36 of the indoor side chamber 21, and this air is filtered by the air filter. 38, indoor heat exchanger 1
1. After passing through the electric heater 55, the cross flow fan 12
Is blown into the room through the blow-out grill 43. The indoor heat exchanger 11 cools the indoor air taken into the indoor circulation chamber 36 to cool the room during the cooling operation of the air conditioner 10, and heats the indoor air to perform the indoor operation during the heating operation.

As shown in FIG. 6, by sliding the ventilation shutter 49, the ventilation opening 48 is fully opened at a position where the small hole group 51A of the ventilation shutter 49 coincides with the ventilation opening 48, and the small hole group 51A is opened. And the ventilation shutter 49 blocks the ventilation opening 48.
Is fully closed. In addition, the opening position of the ventilation opening 48 is adjusted to an arbitrary position such as half-open or ⅔ open by the sliding position of the ventilation shutter 49. By this opening operation of the ventilation opening 48, the outside air flowing into the outdoor chamber 22 is guided to the cabinet 19 as shown by the arrow C in FIG. Ventilation openings 48
And is introduced into the outside air introduction chamber 37.

Here, the ventilation opening 48 is formed so as to be inclined downward toward the outdoor chamber 22 side. As a result, the flow area of the outside air between the second top surface 42 and the cabinet 19 is expanded as compared with the case where the second top surface 42 is horizontal. Further, the small hole 51 of the ventilation shutter 49 shown in FIG. 6 is formed with a hole diameter significantly smaller than the opening area of the ventilation opening 48. As a result, the small hole 51 functions as an air filter and is set to have a hole diameter that prevents invasion of insects and the like.

As shown in FIG. 5, the ventilation / ventilation section 50A has a plurality of vent holes 50 arranged in parallel at the lower part of the indoor fan casing 34 by cutting and raising or the like, and is formed in a shutter door shape. A plurality of the ventilation ventilation parts 50A are provided in the longitudinal direction of the indoor fan casing 34 except for the position corresponding to the drain opening 44 of the partition plate 20.

As shown in FIG. 3, the cross flow fan 1
At the time of rotation of 2, the negative pressure is provided below the cross flow fan 12 in the indoor circulation chamber 36, that is, in the vicinity of the ventilation ventilation section 50A. For this reason, as shown by the arrow C in FIG. 3, the ventilation hole 4 of the ventilation shutter 4 and the small hole 51 of the ventilation shutter 4 and the second top surface 42.
The outside air introduced into the outside air introduction chamber 37 through 8 flows downward through the outside of the curved indoor fan casing 34, and enters the indoor circulation chamber 36 through the ventilation holes 50 of the plurality of ventilation ventilation portions 50A. Be guided. The outside air introduced into the indoor circulation chamber 36 mixes with the indoor air conditioned by the indoor heat exchanger 11, and as shown by an arrow B in FIG. It is introduced into a room and fresh air is supplied to this room.

Further, as shown in FIG. 5, the ventilation shutter 4
An operation lever 54 is integrally coupled to one end of the operation lever 9. As shown in FIGS. 2 and 6, the operating lever 54 is provided so as to extend toward the indoor heat exchanger 11 side and can be operated when the front panel 18 is removed. By operating the operation lever 54 in the horizontal direction, the ventilation shutter 49 is directly slid without using a wire or the like,
The opening of the ventilation opening 48 can be adjusted to any value, such as a half-opening operation or a fully opening or closing operation.

By the way, as shown in FIG.
The outdoor heat exchanger 13 is placed inside the outdoor chamber 22 on the bottom plate 16 on which is erected. The bottom plate 16 is made of a diaphragm material having high malleability and easy to stretch. As shown in FIG. 8, a dam member 56 for damming the flow of drain water is integrally formed by drawing on the bottom plate 16 in the vicinity of the outdoor heat exchanger 13, as shown in FIG.

As shown in FIG. 7, the dam member 56 has a central portion 56A extending in the width W direction of the bottom plate 16 and both end portions 56B.
Is formed in a U shape extending in the direction of the indoor side chamber 21. The dam member 56 forms the storage section 32 capable of storing drain water inside the dam member 56.

As shown in FIG. 3, during the cooling operation of the air conditioner 10, the indoor heat exchanger 11 functions as an evaporator,
The outdoor heat exchanger 13 functions as a condenser. The drain water generated in the indoor heat exchanger 11 flows down to the outdoor side chamber 22 side of the bottom plate 16 through the drain pan 33 and the drain opening 44 of the partition plate 20, and is stored in the storage section 32. The excess drain water overflowing from the reservoir 32 is discharged from the drain drain port 57 (FIG. 7). The drain water stored in the storage portion 32 is scraped up and scattered by the rotation of the slinger ring 31 in the propeller fan 14 as described above, and adheres to the outdoor heat exchanger 13. The drain water attached to the outdoor heat exchanger 13 evaporates, and the outdoor heat exchanger 1
The condensing ability of 3 is improved.

During the heating operation of the air conditioner 10, the indoor heat exchanger 11 functions as a condenser and the outdoor heat exchanger 13 functions as an evaporator. This outdoor heat exchanger 1
As shown in FIG. 8, the drain water generated in No. 3 is, on the bottom plate 16, a dam member 56 for mounting the outdoor heat exchanger 13.
The weir member 56 prevents the water from being stored in the outer region 58 and flowing into the reservoir 32 which is the inside of the weir member 56. When the drain water generated by the outdoor heat exchanger 13 flows into the storage section 32, the drain water freezes, and the slinger ring 31 of the propeller fan 14 collides with the frozen drain water and produces abnormal noise. There is a fear. The dam member 56 prevents the drain water generated in the outdoor heat exchanger 13 from flowing into the reservoir 32 in order to prevent the generation of the abnormal noise.

As shown in FIGS. 3 and 6, this dam member 5
6, in particular, the outdoor fan casing 23 is arranged in contact with both end portions 56B of the dam member 56. As a result, the outdoor fan casing 23 is favorably supported by the bottom plate 16 via the dam member 56.

The manufacturing cost of the bottom plate 16 can be reduced as compared with a case where the dam member 56 is manufactured as a separate component from the bottom plate 16, the separate component is fixed to the bottom plate 16, and a sealing process is performed between them.

Since the dam member 56 is integrally formed by drawing, the existence of the dam member 56 causes the bottom plate 16 to be formed.
The strength of can be improved.

In the dam member 56, the central portion 56A is the bottom plate 16
Since the outdoor heat exchanger 13 functions as a condenser, the drain water is stored in the storage portion 32 inside the dam member 56, and the drain water is When the slinger ring 31 of the propeller fan 14 is rotated, the slinger ring 31 scatters to the condenser to improve the condensing capacity, and when the outdoor heat exchanger 13 functions as an evaporator,
It is possible to prevent the drain water generated by the evaporator from flowing into the reservoir 32 inside the weir member 56, freezing the drain water that has flowed in and colliding with the slinger ring 31.

Since the outdoor fan casing 23 for housing the propeller fan 14 contacts the weir member 56 of the bottom plate 16, the weir member 56 allows the outdoor fan casing 2 to operate.
