A left-right louver 16 is provided on the lower surface of the front drain pan 12 so as to be located in the outlet guide path 15. A vertical louver 17 is provided at the outlet 14.

Next, the heat exchanger 10 and the indoor blower will be described in detail. That is, this heat exchanger 10
It comprises a combination of a main heat exchanger 10A formed in an inverted V-shape and an auxiliary heat exchanger 10B provided straight and along a part of the main heat exchanger.

The main heat exchanger 10A is first formed as a connected body in which an arc-shaped portion and a straight portion are connected to each other at their ends. A perforated cut is formed in the connecting portion between the arc-shaped portion and the straight portion, and the actual connecting portion is few. By bending a straight portion from this connection portion at a predetermined angle, an inverted V-shape is formed.

Then, the main heat exchanger 10 is attached to the unit body 1.
In the state where A is assembled, from the place where the arc-shaped part is located on the front side, this part is called the front heat exchanger 9A, and the straight part located behind it is called the rear heat exchanger 9B. .

The front heat exchanger 9A formed in an arc shape is
It is located at a position facing the front suction port 5a. The rear heat exchanger 9B that is inclined obliquely downward from the front to the rear is located at a position facing the upper suction port 5b via the auxiliary heat exchanger 10B.

The auxiliary heat exchanger 10B is provided on the upper side of the rear heat exchanger 9B in parallel to the rear heat exchanger 9B with a small gap therebetween. Therefore, the auxiliary heat exchanger 10B is directly opposed to the upper suction port 5b and obliquely. It will be inclined backward.

Main heat exchanger 10A and auxiliary heat exchanger 10
B is a so-called finned tube type including a number of radiating fins F arranged side by side with a narrow gap therebetween and a heat exchange pipe P penetrating through the radiating fins and fitted by the expanding means. is there.

In particular, auxiliary pipes Pa and Pb, which will be described later, protrude from the lower part of the auxiliary heat exchanger 10B and the side surface of the intermediate part of the front heat exchanger 9A. These auxiliary pipes Pa, Pb
Is inserted through the unit body 1 as described later,
The pipe is routed and connected to a refrigerant pipe extending from an outdoor unit (not shown).

The indoor blower 11 can be easily understood by looking at FIG. In FIG. 1, the heat exchanger 10 is omitted. The indoor blower 11 has a fan motor 11A.
And an unequal-pitch cross flow fan 11B fitted to the rotating shaft a of the fan motor 11A. The fan motor 11A and the cross flow fan 11B have circular shapes with almost the same diameter.

The position of the indoor blower 11 in the unit main body 1 and the position with respect to the heat exchanger 10 are as shown in FIG. 3 and FIG. 1 again. That is, the fan motor 11A is connected to the front heat exchanger 9A and the auxiliary heat exchanger 1A.
It is arranged at the side part of the auxiliary piping side Pa, Pb connected to OB. The cross flow fan 11B includes a fan motor 11A.
At a position where the gap between the heat exchanger and the heat exchanger is as short as possible.
0 are arranged opposite to each other.

In other words, the position of the cross flow fan 11B is accurately set so as to oppose the heat exchanger 10, and the fan motor 11A is arranged based on this position. The cross flow fan 11B is arranged close to the back side of the front heat exchanger 9A formed in an arc shape. Main heat exchanger 10
A is formed in an inverted V-shape by the front heat exchanger 9A and the rear heat exchanger 9B, so that the cross flow fan 11B is located substantially in the middle of the front and rear heat exchanger 9A. The containers 9A and 9B cover the umbrella.

With such a configuration, the rear end of the rear heat exchanger 9B and the rear plate 3 are close to each other, and there is almost no space between them. A certain amount of space is secured between the fan motor 11A and the rear plate 3.

On the other hand, as shown in FIG. 2A, a plurality of regulating projections 20 are integrally provided at predetermined positions on the rear plate. These restricting projections 20 are connected to the fan motor 11
At a position facing the back side of A, there is a predetermined distance from each other along the vertical direction of the rear plate 3.

A piece 20a projecting perpendicularly to the plate surface of the rear plate 3 and forward and a piece 20b bent from the front end thereof in parallel with the plate surface of the rear plate 3 are provided. In L
It is formed in a character shape.

The projecting height of the projecting piece 20a is slightly larger than the diameter of the auxiliary pipes Pa and Pb, and the width of the parallel piece 20b is longer than the length of two auxiliary pipes arranged in parallel. Is also somewhat large.

As shown in FIGS. 1 and 3 again, each of auxiliary pipes Pa and Pb projecting from the side of front heat exchanger 9A.
Is extended obliquely in the direction of the upper end of the heat exchanger 9A.

The two auxiliary pipes Pa and Pb are aligned in parallel, extend horizontally in the direction approaching the rear plate 3, and are housed in the shield pipe 21 in a state where the two are arranged side by side.
A portion which is bent so as to hang vertically in the position immediately before the rear plate, approaches the plate surface of the rear plate 3, and extends downward along the rear plate is inserted into the regulating protrusions 20. Is done.

That is, the provision of the inverted V-shaped heat exchanger 10 allows the front-side heat exchanger 9A and the rear-side heat exchanger 9B to be arranged so that the cross flow fan 11B is covered. Even if the rear plate 3 is arranged close to the heat exchanger 10, the fan motor 11A is arranged at a position protruding from the side of the heat exchanger. Some space is secured.

By utilizing this space, two auxiliary pipes Pa and Pb are inserted. A plurality of regulating projections 20 are provided corresponding to the above-mentioned space, and the auxiliary pipe is connected to the rear plate 3.
The position is regulated between.

A notch 22 is provided at the lower right corner of the rear plate 3 in the drawing. The auxiliary pipes Pa and Pb housed in the shield pipe 21 are routed from the front side to the rear side of the rear plate 3 through the cutouts 22. In addition, a shielding member 23 provided separately is fitted into the notch to close the notch space 22 and shield the auxiliary pipes Pa and Pb stored in the shield pipe 21.

The shielding member 23 is as shown in FIG. Thus, the indoor blower 11 is driven with the refrigeration cycle operation. Fan motor 11A
As a result, the cross flow fan 11B is driven to rotate, and the air to be conditioned is sucked into the unit body 1 from the front and upper suction ports 5a and 5b.

The heat exchange air flows through the front heat exchanger 9A arranged opposite to the front suction port 5a to exchange heat.
At the same time, the heat exchange air flows through the rear heat exchanger 9B via the auxiliary heat exchanger 10B arranged opposite to the upper suction port 5b to exchange heat.

The heat exchange air which has exchanged heat with these heat exchangers 9A, 9B, 10B is blown out from the transverse flow fan 11 through the blow-out opening 14 through the blow-out guide path 15, thereby achieving air conditioning of the room to be air-conditioned.

Since the front heat exchanger 9A is formed in an arc shape and its bending direction extends from the front to the rear, the front heat exchanger is bent so as to surround a part of the peripheral surface of the cross flow fan 11B. It is in a state.

The distance between the rear side edge of the front heat exchanger 9A and the surface of the cross flow fan 11B is gradually approaching and gradually increasing.
-57073).
Therefore, the wind speed distribution in the heat exchanger 10 is made uniform, and the blowing noise of the heat exchange air passing through the heat exchanger is reduced.

The heat exchanger 10 is formed in an inverted V-shape, and the indoor blower 11 is disposed substantially in the middle of the front and rear heat exchangers 9A in consideration of the blowing characteristics, so that the fan motor 11A A certain gap is formed between the rear plate 3 and the rear plate 3.

By inserting the shield pipe 21 accommodating the auxiliary pipes Pa and Pb into the gap, it is not necessary to provide a space for inserting the auxiliary pipe between the fan motor 11A and the cross flow fan 11B as in the related art. Therefore, the distance between the motor and the fan can be reduced accordingly. This shortens the unit body 1 in the width direction, thereby achieving a reduction in size.

If the width of the unit body 1 is maintained as before, the heat exchanger 10 can be expanded in width to increase the heat capacity, and the axial length of the cross flow fan 11B can be increased accordingly. Lengthen it to increase the air flow.

The regulating projections 20 provided on the rear plate 3 are provided.
Is a shield pipe 2 in which auxiliary pipes Pa and Pb are accommodated.
1 and the fan motor 11A. In other words, even if the fan motor 11A and the cross-flow fan 11B are vibrated by the rotational drive, these vibrations and the auxiliary piping
Since the regulating protrusion 20 is interposed between the shield pipe 21 in which the b is accommodated, the auxiliary pipe does not come into contact with the fan motor, so that no noise is generated.

Since the auxiliary pipes Pa and Pb pass through the inside of the rear plate 3, the work of assembling the heat exchanger 10 to the rear plate 3 is performed.
Unlike the conventional case, the rear plate does not need to be sandwiched between the heat exchanger and the auxiliary pipe, so that the workability is good and the rigidity of the rear plate 3 is obtained from the place where the notch is not provided in the upper portion of the rear plate which requires the most strength. .

In the manufacturing process of the indoor unit, the heat exchanger 10 is assembled after the indoor blower 11 is attached to the rear plate 3 and fixed. At the time of this assembly, the rear plate 3 is placed on the belt conveyor ( You can do that work while you lie down).

That is, the auxiliary pipes Pa and Pb are
2, the auxiliary pipe can be passed through the back side of the rear plate 3, and the heat exchanger 10 can be placed in a predetermined position without lifting the rear plate 3.

FIGS. 4A and 4B are convenient for explaining the fourth aspect. Here, instead of the regulating projection 20 described above, a rib 25 is integrally provided on a shielding member 23A that shields the notch 22 of the rear plate 3. Since all other components are the same as those described above, the same numbers are assigned and new explanations are omitted.

The rib 25 is interposed between the auxiliary pipes Pa and Pb and the fan motor 11A. Since the shielding member 23A is attached to the notch 22 at the lower portion of the rear plate 3, the rib 25 protruding therefrom is inserted between the auxiliary pipe and the fan motor from below.

When the auxiliary pipes Pa and Pb pass through the gap between the rear plate 3 and the fan motor 11A, the auxiliary pipes easily come into contact with the fan motor. The contact of the pipe with the fan motor is reliably regulated.

FIGS. 5 to 7A and 7B are convenient for explaining the fifth aspect. However, in this case, since the auxiliary pipe is routed from the upper part of the rear plate 3A to the back side of the rear plate 3A, a shielding member for the notch is unnecessary, and except for the rear plate 3A described later, other auxiliary units are provided. The constituent components are the same as those described above with reference to FIGS. 1 to 3, and thus, the same reference numerals are given here, and a new description will be omitted.

The rear plate 3A is connected to the fan motor 11A.
A concave groove 26 is integrally provided along a vertical direction at a portion facing the groove. The upper end of the concave groove 26 has a rear plate 3
A is a shape protruding toward the near side from the upper end, and is therefore open.

The protruding surface of the concave groove 26 is
It is in a position so close that it does not contact the peripheral surface of A. This width dimension is equal to two auxiliary pipes Pa and P in the shield pipe 21.
It is set so that there is still room even if b is accommodated side by side.

The two auxiliary pipes Pa and Pb projecting from the side of the front heat exchanger 9A are connected to the fan motor 11
After being bent horizontally in the upper part of A and housed in the shield pipe 21, it is inserted into the inside from the upper end opening of the concave groove 26. And the auxiliary pipes Pa, Pb
Is extended along the outer surface of the groove 26 while being housed in the groove.

That is, the conventional fan motor 11
There is no need to provide a space for inserting an auxiliary pipe between A and the cross flow fan 11B, and the distance between the motor and the fan can be shortened accordingly. This shortens the unit body 1 in the width direction, thereby achieving a reduction in size.

If the width of the unit body 1 is maintained as usual, the width of the heat exchanger 10 can be increased to increase the heat capacity.
By increasing the length of B in the axial direction, an increase in the amount of air to be blown is obtained.

Auxiliary piping Pa, Pb and fan motor 11B
Between the fan motor 11 and the
Even if there is vibration accompanying the driving of B, the auxiliary pipes Pa and P
Contact with b is surely regulated and does not lead to noise.

In the above embodiment, the auxiliary pipes Pa, Pb
Are collectively accommodated in the shield pipe 21. However, as described in claim 6, the auxiliary pipes Pa and Pb may be individually divided and accommodated in the shield pipe. With such a configuration, it is possible to save space compared with the case where the shield pipes are collectively housed.

FIGS. 3 and 7 show that the auxiliary pipes Pa and Pb are arranged in parallel along the plate surfaces of the rear plates 3 and 3A of the unit body 1. FIG. With this configuration, it is not necessary to arrange the auxiliary pipes back and forth so as to insert the auxiliary pipe into the gap between the fan motor and the cross flow fan as in the related art. That is, the pipes must be twisted forcibly in order to arrange them in front and rear, but such an unreasonable operation is not required to arrange them in parallel. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

Auxiliary piping is inserted into the space between the board and the board. Therefore,
The distance between the fan motor and the cross flow fan is shortened,
The longitudinal direction of the blower and the lateral width of the unit main body are shortened, so that the unit main body can be downsized, and the upper part of the rear plate that requires the most strength is not required to be processed, thereby increasing the rigidity of the rear plate.

If the width of the unit body is the same as the conventional one, the heat capacity of the heat exchanger can be increased, and the heat exchange capacity can be improved. Can be increased.

According to the second aspect of the present invention, the rear plate is provided with a notch through which the auxiliary pipe is inserted, and this notch is shielded by the shielding member after the auxiliary pipe is inserted. The heat exchanger can be mounted on the rear plate while being placed on a belt conveyor and laid down, thereby improving workability.

According to the third aspect of the present invention, since the regulating projection integrally provided on the rear plate is interposed between the auxiliary pipe and the fan motor, the contact of the auxiliary pipe with the fan motor can be reliably restricted. The auxiliary piping does not pick up the vibration of the blower and does not generate noise.
