Further, each of the heat exchanger units A and B is arranged in parallel with a plurality of fins F at a narrow interval to penetrate the heat exchange pipe P formed in a U shape from the left side of the figure. Then, both ends of the heat exchanging pipe P are projected from the right side to connect the U band a to the ends of the adjacent heat exchanging pipes to form a flow path. So-called fin tube type.

In addition, each heat exchanger unit A, B forms a flow path with each other as shown in FIG. 7, and directly connects to the 1st heat exchanger unit A and the 2nd heat exchanger unit B other than a U-band (a). A jumping pipe (b) and an auxiliary pipe (c) for connecting with a refrigerant pipe communicating with an outdoor unit (not shown) are connected, and all of these pipes are identical to each other in each heat exchanger unit (A, B). It protrudes from the right side matched to the position.

On the other hand, the upper blower 15 is disposed at a position opposite to the connection portion between the split intermediate heat exchanger portion 21a and the upper heat exchanger portion 22 constituting the first heat exchanger body A, and the lower blower 16 is arranged in a second position. It is arrange | positioned in the position which opposes the connection part of the intermediate part heat exchanger part 21b and the lower heat exchanger part 23 which comprise the heat exchanger body B. As shown in FIG.

Each blower (15, 16) is composed of a fan motor 28 and one shaft portion is connected to the rotating shaft of the fan motor 28, the other shaft portion is a cross-flow fan 29 that is axially supported by a bearing member (not shown) . The crossflow fan 29 of each blower 15, 16 has the same axial length as the longitudinal dimension of the opposing heat exchanger unit A, B, respectively, and each end part opposes in the forward direction.

Then, the upper fan motor receiving portion 30 is installed on the upper right side of the rear plate 3 is fixed to the fan motor 29 of the upper blower (15). Moreover, the bearing member attachment part 31 is provided in the left part of the same height, and the bearing member which comprises the upper blower 15 is attached and fixed.

On the lower side, the lower fan motor receiving part 32 is installed on the left side, and the fan motor 28 of the lower blower 16 is attached and fixed. Moreover, the bearing member attachment part 33 is provided in the right part of the same height, and the bearing member which comprises the lower blower 16 is attached and fixed.

Therefore, the fan motor 28 of the upper blower 15 and the fan motor 28 of the lower blower 16 are attached to positions opposite to each other. By attaching to the left and right opposite positions using the same fan motor 28, the air sucked in the same suction port 5 can be ejected in the symmetrical directions of the upper and lower air blow passages 12 and 14, thereby unifying parts. Can be tried.

The upper drain fan 34 is inserted between the first and second heat exchanger units A and B integrally connected to each other through the connecting plates 24a and 24b and falls from the first heat exchanger unit A. Drain water is collected and collected.

As shown in (a) of FIG. 8, the upper drain pan 34 has a bottom portion 34a having a shallow front side and deeply inclined along the rear side, and has a pair of slit portions in the front portion of the left and right sides. 35 is installed.

The connecting plates 24a and 24b are inserted into the slit part 35, and the first and second heat exchanger units A and B united by the slit part 35 are provided. Positioning of the lower drain pan 34 is made.

A screw hole 36 is provided in the vicinity of the slit part 35 at the front side of the upper drain pan 34, and the drain pan fixing part provided in the connecting plates 24a and 24b through an attachment screw. Attached to 37 is fixed.

In addition, a concave portion is formed on the right side of the upper drain pan 34 and a concave portion 38 in which the upper circumference is cut is integrally provided. The concave portion 38 is provided with a jumping pipe b and an auxiliary pipe c that communicate with each other of the first and second heat exchanger units A and B. Therefore, it is not necessary to specifically provide a piping space for the jumping pipe (b) and the auxiliary pipe (c) on the side of the drain pan (34).

As shown to (b) of the said figure, the rib 35a is integrally formed in the upper surface side of each slit part 35, and is formed. In the state in which the upper drain pan 34 of the unitary first and second heat exchanger units A and B are incorporated, the ribs 35a of the respective slit portions 35 are formed on the side surfaces of the connecting plates 24a and 24b. In close contact with each other, the leakage of drain water flowing in the first heat exchanger unit A is prevented.

Moreover, as shown in FIG. 2, the drain pan and guide plate 13 demonstrated above is arrange | positioned below the 2nd heat exchanger unit body B. As shown in FIG. Since the jumping pipe b or the like does not pass through the side of the drain receiver and guide plate 13, the recess 38 is unnecessary and may be flat as in the upper drain pan 34.

However, during the cooling operation of the refrigeration cycle operation, the refrigerant in the outdoor heat exchanger (not shown) flows into the upper heat exchanger portion 22 while flowing into the lower side of the upper intermediate heat exchanger portion 21a and evaporating as shown in FIG.

Then, the upper heat exchanger unit 22 is divided into two passes and flows into upper portions of the lower intermediate heat exchanger unit 21b and the lower heat exchanger unit 23, respectively. Then, it joins in the lower intermediate | middle heat exchanger part 21b, and flows to the compressor which is not shown in figure. In the heating operation, since the refrigerant flows in the direction opposite to the cooling operation, detailed description thereof will be omitted.

The flow of the refrigerant and the fan motors 28 of the upper and lower blowers 15 and 16 are simultaneously driven in the above directions, so that the air chambers of the air chambers at the suction grille 4 and the suction port 5 in the center of the front panel 2 are united. It is sucked into the main body 1.

In addition, the air-conditioned chamber air sucked from the upper side of the suction port 5 at the boundary of the upper drain pan 34, which is a partition plate, is formed by the first heat exchanger unit A formed by the upper heat exchanger unit 22 and the upper intermediate heat exchanger unit 21a. And heat exchange with the refrigerant delivered thereto.

At the same time, the air chamber to be sucked in from the lower part of the inlet 5 passes through the second heat exchanger unit B consisting of the lower intermediate heat exchanger unit 1b and the lower heat exchanger unit 23, and heat exchanges with the refrigerant delivered thereto.

In this way, the heat exchange air is reliably separated and guided into the upper blower passage 12 and the lower blower passage 14 partitioned by the upper drain pan 34. The heat exchange air guided along the upper blower passage 12 is set at the upper blower outlet 7 and its vicinity by the horizontal blower 6 and the vertical louver 19 to set up and down the direction of the burrs. It blows off from this upper blower outlet 7.

Similarly, the heat exchange air guided along the lower blower 14 is blown from the lower spout 9 by the louver body 20 at the lower spout 9 and its vicinity. The air conditioning of the air-conditioning chamber R is performed by the heat exchange air blown out by the upper and lower blower outlets 7, and 9. As shown in FIG.

In the present invention, the heat exchanger 10 protrudes to the lower side of the intake port 5 and is disposed through the intake port and the space, and the upper heat exchanger part 22 and the lower heat exchanger part disposed in parallel with the intake port. Since it consists of (23), the heat exchange capacity of the heat exchanger 10 is increased by improving the heat exchange capacity, without making the air conditioner main body which is the unit main body 1 large.

In addition, since the intermediate heat exchanger portion 21 protrudes below the intake port 5, the inside of the unit main body 1 has the same upper part as that of the conventional partition plate due to the ventilation resistance to the extent that the intermediate heat exchanger 21 is present. It has an effect that it is partitioned into the lower blower paths 12 and 14, and the respective blower paths 12 and 14 are not influenced by the wind, so that the blowing efficiency is improved and the blowing noise is reduced.

In addition, the intermediate heat exchanger unit 21 is divided up and down to form the first heat exchanger unit A having a " " shape in the upper heat exchanger unit 22 and the upper intermediate heat exchanger unit 21a, and the lower intermediate heat exchanger unit. Since the second heat exchanger unit B having a " <&quot; shape is formed in the lower heat exchanger unit 23 with the 21b, the intermediate heat exchanger unit 21 is disposed at positions close to the upper and lower blowers 15 and 16. It is possible to make the amount of air blown uniform for each heat exchanger portion, thereby to improve the air blow efficiency and to reduce the blow noise.

Since the first heat exchanger single body A and the second heat exchanger single body B are integrally connected to each other through a connecting plate 24a and 24b, an attachment rib of the unit body 1 is easily formed. .

Since the longitudinal size Lb of the second heat exchanger unit B is shorter than the longitudinal size La of the first heat exchanger unit A, the lower blower ( The fan motor 28 of 16) can be arrange | positioned. That is, the fan motor 28 of the same form can be arrange | positioned with respect to the 1st, 2nd heat exchanger units A and B, and the component cost is reduced by commonizing components.

Match the positions of the right side surfaces of the first heat exchanger unit A and the second heat exchanger unit B, and connect the pipes such as the U-band (a), the jumping pipe (b) and the auxiliary pipe (c) to this side. Because of this, the furnace attachment work for connecting such pipes is easily performed.

In the space of the intermediate heat exchanger unit 21, the partition plate 34 partitioning the upper and lower air blowers 12 and 14 is disposed so that the air sucked in the inlet 5 is transferred to the heat exchanger 10. It can be partitioned before it flows in, so that each of the blowers 12 and 14 can be reliably prevented from being influenced by the wind, and the blowing efficiency is improved while blowing noise is reduced.

An upper drain pan 34 is disposed between the first heat exchanger unit A and the second heat exchanger unit B so as to receive the drain water falling from the first heat exchanger unit A. Since the upper and lower blowers 12 and 14 are partitioned, it is possible to ensure the drainage of the drain water to the first heat exchanger unit A and at the same time, the first heat exchanger unit A and the second heat exchanger. The upper blower 12 and the lower blower 14 can be completely divided, including a single body B, and each blower 12, 14 completely prevents the influence of the wind from each other, and thus the blowing efficiency In addition to this improvement, blowing noise is reduced.

In addition, since the upper drain pan 34 is fixed to the drain pan fixing portion 37 provided on the connecting plates 24a and 24b, the upper drain pan 34 is securely attached and the unit is integrated after such integration. Since it can be woven into the main body 1, jaw rib work is performed easily.

Moreover, you may employ | adopt the structure as described below.

That is, as shown in FIG. 9, the suction grill 4A is detachably attached to the front side of the front panel 2 covering the front side of the heat exchanger 10. And the filter attachment part 40 which protruded in the intermediate heat exchanger part 21 side is provided in the part of the front panel 2 which opposes the intermediate heat exchanger 21 which comprises the heat exchanger 10. As shown in FIG. Deodorizing filter 41, which is a filter, is detachably attached to the filter attachment part 40, for example.

Since the deodorizing filter 41 is deodorized in contact with the air to be air-conditioned in the suction port 5, the deodorizing filter 41 obtains a deodorizing effect together with air conditioning to the air-conditioned air chamber. The space where the filter attachment portion 40 protrudes is a space portion formed by the intermediate heat exchanger portion 21 protruding below the suction port 5. That is, since the filter attachment part 40 does not protrude to the suction grill 4A side, the unit main body 1 is not enlarged.

As shown in FIG. 10, the space portion K on the side of the second heat exchanger unit B is a space for arranging the fan motor 28, which is an electric component, and the suction opposed to the space portion K. A filter attachment part 40A for attaching the deodorization filter 41 to the grille 4 may be provided.

Therefore, the filter attachment portion 40A does not protrude, and there is no adverse effect such as enlargement of the unit body 1. Since the heat exchanger 10 does not face the deodorization filter 41, the deodorization filter 41 does not leak by the drain water generated in the heat exchanger 10 and is not affected by the heat exchanger.

Moreover, in the said embodiment, although the said heat exchanger 10 was divided into the 1st heat exchanger single body A and the 2nd heat exchanger single body B, it is not limited to this.

For example, as shown in FIG. 11A, the intermediate heat exchanger portion 21A is integrally connected to the upper heat exchanger portion 22 and the lower heat exchanger portion 23 parallel to the suction port 5. This intermediate heat exchanger portion 21A is formed by bending in an inverted " " shape and protrudes below the suction port 5.

As shown in (b) of the figure, the intermediate heat exchanger portion 21B is integrally connected to the upper heat exchanger portion 22 and the lower heat exchanger portion 23 parallel to the suction port 5. The intermediate heat exchanger portion 21B is formed by bending in a trapezoidal shape and protruding below the suction port 5.

As shown in (c) of the figure, the intermediate heat exchanger portion 21C is integrally connected to the upper heat exchanger portion 22 and the lower heat exchanger portion 23 parallel to the suction port 5. The intermediate heat exchanger portion 21C is formed in a curved shape and protrudes below the suction port 5.

In any configuration, the upper blower 15 is disposed opposite the connecting portion between the intermediate heat exchanger portions 21A, 21B, and 21C and the upper heat exchanger portion 22 so as to face the connecting portion between the intermediate heat exchanger portion and the lower heat exchanger portion 23. Blower 16 is disposed. Therefore, the same effect as the embodiment described above is exhibited.

In addition, "34" is a partition plate in some structure, In this case, although the partition plate 34 does not partition each heat exchanger 22 and 23 itself, the air-conditioning chamber 12 which blows up the air-conditioned chamber air suctioned 12 , 14), and can exhibit sufficient effects as in the above-described embodiment.

As described above, in the invention of claim 1, the air conditioner main body is not enlarged because the heat exchanger is composed of an intermediate heat exchanger portion disposed below the intake port and spaced through the space and an upper heat exchanger portion and a lower heat exchanger portion disposed in parallel with the intake opening. Instead, the heat exchange capacity of the heat exchanger is increased, thereby improving the heat exchange capacity.

In the invention of claim 2, since the intermediate heat exchanger part is divided up and down, the first heat exchanger part having a "<" shape is formed in the upper heat exchanger part, the split intermediate heat exchanger part, the split intermediate heat exchanger part, and the lower heat exchanger part, respectively.
