Abstract

PROBLEM TO BE SOLVED: To prevent the generation of dew condensation without pasting an insulating material on the side of an air supply passage of a bucket by forming a flow passage which distributes drain water between a third wall provided between a first wall and a second wall and the first wall. SOLUTION: During cooling operation, dew condensation is generated in a heat exchanger where drain water is produced and drops. The drain water W collected on a rear side drain pan 6b located in a higher elevation than a front side drain pan 6a flows along the flow passages of a right bucket 30a and a left bucket 30b and is collected in the front side drain pan 6a. The collected water is drained outside from the front side drain pan 6a collectively and processed. Since the drain water W, which flows from the rear side drain pan 6b to the front side drain pan 6a, is positioned so that a drain outlet of the rear side drain pan 6b may be opposed to the flow passage, and a flow passage P flows between a first wall 31 and a third wall 33 so that the drain water W may not cool the second wall 32. Therefore, no condensation is generated on a wall surface 32a on a flow passage 17 of the second wall 32.

In the unit body of the indoor unit, the air in the air-conditioned room is sucked into the inside of the unit body from the suction port provided in the front panel, passes through the heat exchanger arranged inside the unit body, and exchanges heat. It is designed to be blown out again into the air-conditioned room from an outlet provided in the lower part.

Further, in the air conditioner, the heat exchanger has a reverse V
There is a type that is arranged in a letter shape. The main part of such a unit body 1 is configured as shown in FIG. 7, for example.

That is, reference numeral 3 in FIG. 7 denotes a rear plate which constitutes the unit main body together with the front panel (not shown).
An inverted V-shaped heat exchanger 5 shown by a chain double-dashed line in FIG. 7 is arranged on the front surface of the rear plate 3. The heat exchanger 5 includes a front heat exchanger 5a located in the front and a rear heat exchanger 5 located in the rear.
b.

The front heat exchanger 5 which constitutes this heat exchanger 5

Both ends of the indoor blower 11 are supported by blower support portions 15 and 16, and a blower path 17 is formed between the blower support portions 15 and 16.
Further, on both sides of the air duct 17, there are gutters 20a, 20
b is formed.

The left and right gutters 20a, 20b have upper ends communicating with both end portions of the rear drain pan 6b, and lower end portions communicating with both end portions of the front drain pan 6a. That is, the left and right gutter portions 20a and 20b are provided on the rear drain pan 6

The air conditioner thus constructed is
By performing the refrigerating cycle operation for the heat exchanger 5 and driving the indoor blower 11 to rotate the cross flow fan 12, the air to be conditioned indoor air is introduced from the suction port to the unit main body 1.
It is sucked in and passes through the heat exchanger 5 for heat exchange. The heat-exchanged air after the heat exchange is guided to the air passage 17 and blown out from the outlet into the air-conditioned room.

During the cooling operation, dew is condensed on the heat exchanger 5, and drain water is generated and dropped in the drain pan 6. That is, the drain water dripping from the front heat exchanger 5a is received by the front drain pan 6a, and the drain water dripping from the rear heat exchanger 5b is received by the rear drain pan 6b.

The rear drain pan 6b is the front drain pan 6a.
The drain water collected in the rear drain pan 6b from the higher position than the drain drain pan 6b has left and right gutters 2 formed at both end portions.
0a, 20b and is collected in the front drain pan 6a. Then, drainage treatment is performed collectively from the front drain pan 6a to the outside of the room.

Here, the structure of the left and right gutter portions 20a, 20b will be described. Since the left and right gutter portions 20a and 20b are formed symmetrically, only the gutter portion 20a will be described. In addition, w in FIG. 8 indicates drain water. That is, as shown in FIG. 8, the gutter portion 20 a includes a first wall portion 21 positioned outward in the width direction of the unit main body 1 and the first wall portion 2.
The second located on the air passage 17 side of the unit main body 1 than the first
It was composed of the wall 22 and the plate-like member 23 connecting them, so that the drain water w could flow therethrough.

[0014]

The unit body 1 of the conventional air conditioner described above has the following problems. That is, since the cold drain water w flows from the rear drain pan 6b to the front drain pan 6a via the left and right gutter portions 20a and 20b, the wall surface 2 of the second wall portion 22 on the air passage 17 side.
Condensate on 2a. Moisture generated by this dew condensation is discharged from the outlet into the air-conditioned room by the wind flowing through the air passage 17.

On the other hand, a method of attaching a heat insulating material in order to prevent dew condensation on the wall surface 22a of the second wall portion 22 on the side of the air passage 17 can be considered. However, when the heat insulating material is peeled off due to the deterioration of the adhesive material with the passage of time, the heat insulating material is removed by the cross flow fan 1.
There is a risk of contacting the 2 and generating an abnormal sound.

[0016] Therefore, an object of the present invention is to provide an air conditioner which prevents the occurrence of dew condensation and does not discharge drain water into an air-conditioned room without attaching a heat insulating material to the air duct side of the gutter. I am trying.

The heat exchanger 5 is formed in an inverted V shape inside the heat exchanger 5, that is, between the front heat exchanger 5a and the rear heat exchanger 5b so as to be covered by these heat exchangers. The indoor blower 11 is arranged.

As shown in FIG. 3, the indoor blower 11 has a cross flow fan 1 having the same axial dimension as the width dimension of the heat exchanger 5.
2, a fan motor 13 connected to an end plate 12b on one side of the cross-flow fan 12 via a rotary shaft 13a, and a support shaft 12a protruding from an end plate 12c on the other side of the cross-flow fan 12. And a bearing 14 that is pivotally supported.

On the other hand, a first blower support portion 15 is integrally formed on one side portion (right side portion) of the rear plate 3 in the width direction,
The second blower support portion 16 is integrally formed on the other side portion (left side portion). A blower path 17 is formed between the blower support portions 15 and 16.

Further, both sides of the air passage 17 are recessed with a narrow width dimension, and the trough portion 30 is formed in this recess.
a, a gutter portion 30b is formed. The outlet 2c is opened along the front end of the air passage 17. The front drain pan 6a is provided along the front end of the outlet 2c, and the rear drain pan 6b is provided in the air passage 1

No condensation occurs on the side wall surface 32a, and it is possible to prevent water droplets from splashing into the air-conditioned room due to condensation.

Further, in the unlikely event that the drain water w from the rear drain pan 6b is large and the drain water w overflows in the flow path P, the drain water w remains between the second wall portion 32 and the third wall portion 33. Since it flows in, the drain water w can be prevented from being sucked into the air passage 17. At this time, the third wall 3
Since the upper edge of 3 is formed lower than the upper edge of the second wall portion 32, the water surface of the drain water w is blocked by the second wall portion 32 from the wind flowing through the air passage 17, and the drain water w is blown. Road 17
