DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window type air conditioner.

[0002]

2. Description of the Related Art Generally, a window-type air conditioner is provided with an installation frame on a window frame, and discharges heat generated by an outdoor heat exchanger during a cooling operation to the outside of a room using a half-opened window opening. It is installed and used. Among these, there is a type in which the air conditioner does not protrude out of the window so that the window can be completely closed.This includes a drain guide for discharging drain water generated during cooling operation to the outside. When the window is opened, the tip of the window is opened so that it can be drained through a drain pipe, and when the window is closed, it is stored in the room.

FIG. 6 shows a partial top view of a first conventional example with the window closed. In FIG. 6, reference numeral 1 denotes a gutter-shaped synthetic resin drain guide provided at the lower part of the main body of the air conditioner, which comprises a circular tip portion 2 and a water guiding portion 3, and a drainage portion is provided at the bottom of the tip portion 2. A hole 4 is formed. The drain guide 1 is urged so that the distal end portion 2 rotates in the direction of arrow A about the rotation center O at the end portion on the water guide portion 3 side.

When the door 5 of the window on which the air conditioner is installed is opened in the direction of arrow B, the tip 2 of the drain guide 1 passes over the edge of the door frame 6 and protrudes out of the room during the opening. The drain hole 4 communicates with the drain pipe via the drain receiver. As a result, drain water generated by the operation is discharged to the outside.

When the door 5 is closed, the door frame 6 pushes the drain guide 1 sequentially from the water guide 3 to the tip 2 against the urging force. Rotate in the direction. When the door 5 has been closed, the drain guide 1 is stored indoors.

However, when the door 5 is suddenly opened in the direction of arrow B in the above-described configuration, the tip 2 of the drain guide 1 and the edge of the door frame 6 may interfere depending on the shape of the door frame 6. However, there is a possibility that the front end portion 2 cannot get over the edge of the door frame 6 and the window cannot be opened.

In order to eliminate such a state, FIGS.
The inventors have completed the configuration shown in FIG. 7 is a perspective view of a main part, FIG. 8 is a partial sectional view, and FIG. 9 is a partial top view in a state where a window is closed.

In FIGS. 7 to 9, reference numeral 7 denotes a main body.
Reference numeral 8 denotes an installation frame, 9 denotes a window frame to which the door 5 is attached so as to be openable and closable, 10 denotes a drain receiver attached to the window frame 9, and 11 denotes a gutter-shaped member provided at a lower portion of the main body 7. It is a drain guide made of synthetic resin formed in the above. The drain guide 11 includes a circular tip 12 and a water guide 13, and the tip 12 has a rotating body 14 having a disc part with a larger diameter than this.
Is rotatably provided on a rotating body support shaft 15 erected at the bottom, and a cap nut 16 is screwed to a tip of the rotating body support shaft 15. Thereby, the tip portion 12 is covered with the rotating body 14 so as to provide a gap between the tip portion 12 and the upper end of the side wall. A drain pipe 17 is connected to the drain receiver 10, and a drain hole (not shown) is formed at the bottom of the tip 12.

The drain guide 11 is urged so that the tip 2 rotates in the direction of arrow A about the rotation center O at the end on the side of the water guide 13.

When the door 5 is opened in the direction of arrow B, the rotating body 14 provided at the distal end portion 12 of the drain guide 11 hits the edge of the door frame 6 during opening, and the door 5 is opened. Direction, and at the same time, the drain guide 1
The distal end portion 12 rides over the edge of the door frame 6 so as to protrude to the outside of the room so as to slightly rotate in a direction opposite to the direction of FIG. Even when the door 5 is opened sharply in the direction of arrow B when the door 5 is opened, the rotating body 14 pivots in the direction of arrow C although the edge of the door frame 6 violently hits the outer peripheral portion of the rotating body 14 and the drain guide 11 rotates a little in the direction opposite to the direction of arrow A, and the tip 12 gets over the edge of the door frame 6. For this reason, it does not happen that the front end portion 12 and the edge of the door frame 6 interfere with each other and the door 5 cannot be opened.

The drain hole of the distal end 12 projecting outside the room communicates with the drain pipe 17 via the drain receiver 10. As a result, drain water generated by the operation is discharged to the outside.

When the door 5 is closed, contrary to the case where the door 5 is opened, the door frame 6 sequentially pushes the drain guide 11 from the water guide 13 to the tip 12 against the urging force, and pushes the drain guide 11 in the direction of the arrow A. , And the rotating body 14 is further rotated in the direction opposite to the arrow C so that the distal end portion 12 passes over the door frame 6. When the door 5 has been closed, the drain guide 11 is housed indoors.

On the other hand, in the case of draining the drain water to the outside of the room through a drain pipe, if the drain water is attached to an apartment house or the like, an appropriate drainage place cannot be obtained or the drain pipe is difficult to be provided. In some cases, the drain water generated by the operation is evaporated in the air conditioner so that the drain water is not discharged outside the device.

Hereinafter, a second conventional example will be described with reference to FIGS. FIG. 10 is a perspective view seen from the outdoor side, FIG. 11 is a transverse sectional view, and FIG. 12 is a perspective view of the outdoor side heat exchanger.

In FIGS. 10 to 12, reference numeral 21 denotes a main body (not shown) which houses a compressor and the like at a lower portion, and reference numeral 22 denotes a partition plate for dividing the inside of the main body 21 into an outdoor side and an indoor side.

The outdoor heat exchanger 23 includes a heat exchange pipe 34 provided to meander in a vertical plane, and a plurality of horizontal heat exchange pipes provided to be perpendicular to the heat exchange pipe 34 and to be vertically stacked. Fin 35.

When the cooling operation is started, the water spray fan 32 rotates, and the drain water generated in the indoor heat exchanger 25 flowing into the water spray part 31 is scooped up by the water spray fan 32 and scattered, and the outdoor heat exchange is performed. Horizontal fins 35 of vessel 23
Water droplets adhere to the surface. Thus fin 3
The water droplets of the drain water adhering to 5 have an increased temperature as the outdoor heat exchanger 23 serves as an evaporator during the cooling operation.
Since the outdoor heat exchanger 23 is provided in the ventilation path of the outdoor blower 24, it evaporates quickly, and the outdoor blower 2
4, the air is discharged from the outdoor air outlet 28 to the outside of the room.

However, in the second conventional example, when the continuous operation is performed in a state where the humidity is high, the water sprinkling section 31
It is conceivable that the amount of drain water supplied to the outdoor heat exchanger 23 becomes a large amount in a state of water droplets, and exceeds the evaporation processing capacity of the outdoor heat exchanger 23. When drain water exceeding the evaporation processing capacity is generated in this manner, the water not treated in the outdoor heat exchanger 23 is again discharged to the sprinkling section 3.
1, the water may overflow from the water sprinkling section 31 and further overflow the main body 21, or may become large water droplets directly from the outdoor heat exchanger 23 to the outside of the room.

For this reason, in the case where the drain water is evaporated in the main body 21 so as not to be drained to the outside, the processing capacity of the drain water is further improved so that the continuous operation can be performed even in a high humidity environment. Is strongly desired.

[0021]

When the continuous operation is performed in a high humidity environment as described above, all the drain water cannot be evaporated by the outdoor heat exchanger, and the untreated drain water is discharged to the outside. There is a risk of overflowing.

2 is a cross-sectional view, FIG. 3 is a cross-sectional view of a main part,
FIG. 4 is a longitudinal sectional view of a main part, and FIG. 5 is a partial sectional view showing a modification of the evaporation promoting member.

In FIGS. 1 to 4, reference numeral 41 denotes a vertically long rectangular parallelepiped body in which a refrigeration cycle is formed. And body 41
The upper part is divided by a partition plate 42 having a substantially S-shaped cross section so that the front part is the indoor side and the rear part is the outdoor side.

Further, the main body 41 has a vertically long indoor air inlet 44 provided with a front grill 43 and a filter (not shown) at the front of the room and a vertically long indoor air outlet 46 provided with a louver 45 for adjusting the wind direction. Have been. Also, inside the divided main body 41 on the indoor side, the indoor air blower 47 of the cross flow fan is provided on the indoor air outlet 46 side.
Are arranged so as to have a rotation axis in the vertical direction, and this indoor air intake port 4 is provided on the indoor air intake 44 side.
The indoor heat exchanger 48 is provided so as to be opposed to the heat exchanger 4.

On the other hand, a vertically long outdoor air inlet 49 and a vertically long outdoor air outlet 50 are formed on one side of the rear side of the outdoor side of the main body 41, and a water spouting section 51 is formed along the other side. One surface of the vertically long evaporation promoting member 52 is exposed. In the interior of the divided main body 41 on the outdoor side, an outdoor blower 53 of a cross flow fan is disposed on the outdoor air outlet 50 side like the indoor side so as to have a rotation axis in the vertical direction. Outside air intake 4
An outdoor heat exchanger 54 is provided on the 9 side so as to face the outdoor air intake 49. The outdoor heat exchanger 54 is provided so as to meander in a vertical plane, and is orthogonal to the heat exchange pipe 55 so as to promote heat exchange in the heat exchange pipe 55 and is stacked vertically. And a large number of fins 56 in the horizontal direction.

Further, inside the outdoor side of the main body 41, a water sprinkling section 51 in which one side of the evaporation promoting member 52 is exposed at the rear side of the outdoor side.
Is provided adjacent to the side of the outdoor heat exchanger 54. The water sprinkling section 51 has a drain receiving member 57 for receiving drain water condensed in the indoor heat exchanger 48 during the cooling operation.
And a sprinkling fan 59 that is driven and rotated by a motor 58 in the drain receiving member 57 to scoop up the drain water into small water droplets and scatter into the water sprinkling section 51.

Further, the evaporation promoting member 52, one side of which is exposed on the rear side of the outdoor side of the main body 41, is provided with a water sprinkling section 51 so that the water drops scattered by the water sprinkling fan 59 are caught and adhered.
For example, it is formed of a porous body having a degree of air permeability such that water droplets formed by foaming polyurethane or synthetic fibers formed in a net shape, or non-woven laminated synthetic short fibers do not penetrate. . Note that 6
Numeral 0 denotes a partition wall that supports and isolates the motor 58, and 61 denotes a main body that is adjacent to the lowermost end of the
1 is a gutter-shaped member provided so as to partially protrude from the rear surface of the outdoor side, whereby water not retained by the evaporation promoting member 52 and not evaporated is collected by the drain receiving member 57.

With the above configuration, when the cooling operation is started, the sprinkling fan 59 rotates, and the drain water generated in the indoor heat exchanger 48 flowing into the drain receiving member 57 of the sprinkling section 51 is discharged. The water is scraped and scattered by 59 and adheres to the horizontal fins 56 of the outdoor heat exchanger 54 as small water droplets. The water droplets of the drain water adhering to the fins 56 pass through the fins 56 due to the temperature of the outdoor heat exchanger 54 raised by the cooling operation and the provision of the outdoor heat exchanger 54 in the ventilation path of the outdoor blower 53. It evaporates quickly due to the flowing wind, and the outdoor blower 5
With the air taken in by 3, the air is discharged outside from the outdoor air outlet 50.

At the same time, the drain water that has been scooped up and scattered by the water spray fan 59 and captured and adhered to the evaporation promoting member 52 penetrates and diffuses by capillary action or the like, and spreads greatly within the evaporation promoting member 52. As a result, a large amount of drain water is held in the evaporation promoting member 52, and is discharged to the outside of the room by spontaneous evaporation from one surface of the evaporation promoting member 52 exposed to the rear surface on the outdoor side. The water collected without evaporating below the evaporation promoting member 52 is collected by the gutter-shaped member 61, returned to the drain receiving member 57, scooped up by the water spray fan 59, scattered and evaporated.

As a result, the drain water evaporating process accompanying the cooling operation is performed not only through the fins 56 and the like of the outdoor heat exchanger 54 but also by the evaporation promoting member 52 having one surface exposed on the outdoor rear surface. The drain water treatment capacity is greatly improved. In addition, since the evaporation promoting member 52 has a large water retaining capacity, a large amount of drain water can be held in the evaporation promoting member 52. For this reason, there is no danger that the drain water overflows outside the main body 41 or drip outside the room even when the continuous operation is performed in an environment of high humidity.

In the above embodiment, a porous body having a flat surface and air permeability is used as the evaporation promoting member 52. However, a partial cross-sectional view may be configured as in a modification shown in FIG. . That is, the evaporation promoting member 52 'has an uneven surface having convex portions 52a of a predetermined height on both front and rear surfaces, whereby the evaporation area is increased, natural evaporation is promoted, and the treatment capacity of the drain water is further increased. Still further, the projection 52
a may be a ridge or a protrusion, or may be provided only on one side.
