The present invention relates to an indoor unit of an air conditioner formed in an inverted V shape, and more particularly, to an improvement in the treatment structure of effluent water falling from a heat exchanger.

Generally used air conditioner is composed of an indoor unit arranged in the air-conditioning chamber and an outdoor unit arranged outdoors, and these units are connected to each other by a refrigerant pipe and an electric wiring.

On the user side, producers are demanding miniaturization and reduced space for these units. Therefore, each producer meets these conditions and tries to increase the heat exchange capacity.

An indoor unit of an air conditioner employing a heat exchanger is disclosed, for example, in Japanese Utility Model Publication No. 4-106425. The heat exchanger is a front side heat exchanger and a rear side facing each of the front panel and the upper panel constituting the main body. Side heat exchanger. This heat exchanger is formed in inverted V shape.

In this type of heat exchanger, it is possible to secure a larger heat exchange area than the general flat heat exchanger and to suppress the height of the heat exchanger itself. Therefore, the heat exchange capacity can be increased and the height of the unit body can be reduced.

In the heat exchanger formed in such an inverted V shape, outflow water is simultaneously generated in the front heat exchanger and the rear heat exchanger. The effluent water generated at the same time is collected by falling into the front side drain pan disposed under the front side heat exchanger and the rear side side drain pan disposed under the rear side heat exchanger.

The front and rear drain pans are each manufactured separately. The front drain pan is attached to the front panel and the rear drain pan is attached to the rear panel.

However, the above-described structure has an adverse effect of increasing the number of parts and increasing the manufacturing cost of the molds required for manufacturing each of them, and noises such as thermal expansion are generated from the connecting parts in the assembled state.

In addition, it is necessary to drain the effluent collected in the rear drain pan at the bottom of the rear heat exchanger to the outside from the plurality of drain holes provided in the rear drain pan, but the inside of the rear drain pan is maintained at the vacuum pressure during air conditioning so that the blower rotates. Negative pressure is generated and the rear drain pan draws natural air before heat exchange from the drain. During the cooling operation, air is collected in the cold effluent passage with untreated high humidity and temperature and enters the rear drain pan.

As a result, dew easily forms on the outer circumferential surface of the rear drain pan. Such dew drops from the drain pan to the blower and flows into the air-conditioned chamber together with the cooled air.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide an indoor unit of an air conditioner that can be manufactured and assembled in a simple manner at a low cost, and receives the effluent generated in the heat exchanger to produce dew on a drain pan.

The other part of the pipe 29 of the cover member 23A has an inverted U-shaped cross section. The open side edge of the part having an inverted U-shaped cross section is parallel to the bottom surface of the first drip tray 17A having a predetermined interval therebetween, and the arrangement of the cover member 23A is fitted in the drip tray 17A. have.

The inner surface portion (bottom surface of the portion having an inverted U-shaped cross section) of the first cover member 23A has a predetermined curvature.

The opposite end of the pipe portion 29 of the first cover member 23A opposite to the pipe portion 29 is engaged with the motor holding member 21 by a hinge 30, commonly called a P-P hinge.

The motor holding member 21 has a holder having a hemispherical holder portion 31, a holder plate 32a and 32b protruding integrally at a substantially central portion of the holder portion 31 and protruding integrally from the holder. It is comprised by the sealing plate 33 which protrudes radially from the part 31. As shown in FIG.

The edge portion of the articulated plate 32a has a hemispherical shape with the same curvature as the hemispherical edge portion of the attachment plate 26A, while the edge portion of the holder plate 32b has the same hemispherical shape with the hemispherical edge portion of the receiving plate 26B. It is formed.

The holder portion 31 has the same curvature as the hemispherical inner surface of the first cover member 23A. The sealing plate 33 is opposed to the first cover member 23A having a hinge 30 inserted therebetween.

As shown in FIG. 5, the motor holding member 21 rotates toward the rear panel 3 about the hinge 30 from the position of the first cover member 23A, which is fitted in the first drip tray 17A. In this case, the space formed by the drip tray 17A is thereby sealed, and a part of the cover member 23A and the holder portion 31 forms a circular portion.

At the same time, the attaching plate 26A and the accommodating plate 26B are aligned with the holder plates 32a and 32b, respectively, and form a spherical hole having a predetermined diameter. In addition, a part of the holder part 31 and the support part 28 of the rear panel 3 form a circular part.

Referring again to FIG. 10, the state of the first cover member 23A is fitted to the first drip tray 17A described in more detail.

The receiving portion 28a, the vertical portion 28b and the inclined portion 28c of the first drip portion 17A constitute a U-shaped cross-section having an upper opening.

The pipe section 29 having a rectangular cross section in the first cover member 23A has an upper opening end engaged with the drain opening member 27 of the rear drain pan 9B, and has an inclined portion constituting a part of the drip tray 17A. And a lower opening end communicating with the upper opening end of 28c). Therefore, the pipe part 29 is aligned with the receiving part 28a and the vertical part 28b which comprise the part of the drip tray part 17A.

Another inverted u-shaped cross section of the pipe portion 29 seals the space formed by the inclined portion 28c.

The means for attaching the indoor blower fan 11 and the heat exchanger 7 to the rear panel 3 will be described with reference to FIG. This means is provided for attaching the indoor blower fan 11 and the fan motor 13 for driving the heat exchanger 7 to the first blower fan support 15.

As described with reference numerals in FIG. 4, after the first cover member 23A is fitted into the first drip tray 17A, the motor holding member 21 is hinged to expose the first blower fan support 15. It rotates about 30, and the fan motor 13 is fitted there.

The fan motor 13 coupled to the transverse fan 12 is located at a location on the first blower fan support part 15, and the motor holding member 21 is rotated about the hinge 30 so as to be shown in FIG. As shown in the figure, a hemispherical holder portion 31 is adapted on the outer circumferential surface of the fan motor 13.

Therefore, the fan motor 13 is fitted in a circular hole formed by the support portion 28 of the first blowing fan support portion 15 and the holder portion 31 of the motor holding member 21.

Moreover, the boss 13c and the rotating shaft 13a (shown in FIG. 3) protruding from the end of the fan motor 13 are circular holes formed by the edge of the receiving plate 26B and the holder plate 32b. It is fixed inside.

Since the edge portion 21a of the motor holding member 21 contacts the boss c formed integrally with the rear panel 3 as shown in FIG. 10, the end portion 21a is connected to the fixing screw 35. By the boss c. As a result, the motor holding member 21 is securely fixed to the fan motor 13.

The fan motor 13 is positioned axially by fixing the edge of the attachment plate 26A and the end of the boss 13c in the circular hole formed by the holder plate 32a.

As shown in FIG. 6, the boss 13b which protrudes from the other end of the fan motor 13 is supported by the holder member 36 which consists of two parts. As a result, the fan motor 13 is securely fixed to the first blowing fan support part 15.

The first cover member 23A overlaps past the end plate 12b of the cross flow fan 12 and overlaps past the surface of the holder portion 31 of the motor holding member 21 provided with the sealing plate 33 (overlapping). Status is not shown in the drawing). Accordingly, the end plate 12b of the fan 12 is surrounded by the first cover member 23A and a part of the holder portion 31 of the motor holding member 21.

The assembly shown in FIG. 6 is completed by attaching a bearing 14 to the second blower fan support 16, and the heat exchanger 7 is arranged at a predetermined position in the manner described below.

The structure adopted in the second blowing fan support 16 for supporting the bearing 14 will be described.

As shown in FIG. 7, the air passage end plate 37 has an arcuate edge projecting onto the side end of the air passage 18. The accommodating plate 38 constitutes the second blower fan support part 16 which projects away from the end plate 37 at predetermined intervals and projects on the side end portion.

The space between the end plate 37 and the receiving plate 38 forms a second drip tray 17B. In other words, the second drip tray 17B constitutes a part of the air passage 18 extending between the end plate 37 and the receiving plate 38.

Detailed description of the structure of the second drip unit 17B and the relationship between the second drip unit 17B and the rear drain pan 9B will be described with reference to FIGS. 4 and 10. Since the structure is similar to the relationship between the first drip portion 17A and the rear drain pan 9B, it is omitted.

The second cover member 23B is fitted in the second drip tray 17B to seal the space formed by the drip tray 17B. Detailed descriptions of the structure of the second cover member 23B and the relationship between the cover member 23B and the drip tray 17B include the structure of the first cover member 23A described with reference to FIGS. 4 and 10 and the It is omitted because it is similar to the relationship between the cover member 23A and the drip tray 17A.

The bearing base 22 is coupled to the end of the second cover member 23B by a flexible string portion 39 that is thinner than the hinge 30 and can be easily deformed forward, backward, left or right.

The bearing base 22 is composed of a fixing ring 40, a sealing plate 41 projecting radially from the fixing ring 40, a plurality of attachment chips 42 having attachment holes and a plurality of screw holes 43. It is.

As shown in FIG. 8, when the second cover member 23B is fitted in the second drip tray 17B to seal the space formed by the second drip tray 17B, the bearing base 22 is a string. Rotating toward the rear panel 3 about the portion 39, the bearing base 22 is moved to contact the receiving plate 38 constituting the second blowing fan support 16, and the sealing plate 41 of the sealing plate 41. The end is located at the upper edge of the receiving plate 38. In this state, the attachment hole of the attachment chip 42 is aligned with a screw hole (not shown) in the boss formed on the rear panel 3.

Means for attaching the indoor blower fan 11 and the heat exchanger 7 to the rear panel 3 shown in FIG. 9 will be described below. In particular, this means is provided for supporting the second blower fan support 16, the bearing 14 constituting part of the indoor blower fan 11, and for arranging the heat exchanger.

One side of the indoor blower fan 11 is attached to the first blower fan supporter 15, and the cross flow fan 12 is coupled to the rotation shaft of the fan motor 13 in advance.

As described above, the first second cover member 23B is fitted to the second drip unit 17B. The bearing base 22 is then rotated about the string portion 39 toward the outside of the second cover member 23B, thereby exposing the second blowing fan support 16 so that the cross flow fan 12 is attached. Let's do it.

The bearing 14 is fitted in the fitting portion 40 of the bearing base 22.

The bearing base 22 is thereby rotated about the string portion 39 to return on the cover member 23B. In this state, the bearing 14 is held in the fixed portion 40 of the bearing base 22.

Thus, the bearing base 22 is moved to mount the bearing 14 on the support shaft 12a protruding from the other end of the cross flow fan 12.

The bearing base 12 is located on the second blower fan support 16, and the attachment hole of the attachment chip 42 is in communication with a screw hole (not shown) formed in the second blower fan support 16. The bearing base 22 is fixed to the rear panel 3 by a fixing screw inserted through the hole.

Thus, the bearing 14 supporting the cross flow fan 12 is radially attached to the second blower fan support 16, while the fan motor 13 is fixed to the first blower fan support 15. This means fixes the indoor blower fan 11 to the rear panel 3.

Although not shown in the figure, the second cover member 23B overlaps over the end plate 12c of the cross flow fan 12.

Thereby the heat exchanger 7 is positioned so that the attachment hole of the end plate 7c of the heat exchanger 7 is aligned with the screw hole 43 of the bearing base 22, whereby the heat exchanger is connected to the bearing base 22. The screw 35 is inserted through the screw hole so that the 7 is fixed.

In the indoor unit configured as described above, the cross flow fan 12 sucks the air contained in the air conditioning chamber into the unit body 1 through the front inlet port 2a and the upper inlet port 2b. Is rotated so that air passes through the heat exchanger 7 to effect heat exchange of the air. Air is guided into the air passage 18 and blown out through the air outlet 20 into the air conditioning chamber.

The sealing plates 33 and 41 protrude on the motor holding member 21 and the bearing base 22, respectively, and are fitted in the side ends of the heat exchanger 7 formed in an inverted V shape, thereby sealing the heat exchanger. The air of the air conditioning chamber is prevented from being introduced into the heat exchanger 7 through the side end of the heat exchanger.

Effluent water enters the heat exchanger 7 during the cooling operation. The effluent flowing into the front side heat exchanger 7A is collected in the front side drain pan 9A, while the effluent flowing into the rear side heat exchanger 7B is collected in the rear drain pan 9B.

Since the rear drain pan 9B is located higher than the front drain pan 9A, the effluent collected in the rear drain pan 9B is provided with first and second provided on opposite sides of the rear drain pan 9B. Guided to the drip trays 17A and 17B and guided to the front drain pan 9A. Outflow water collected in the front drain pan 9A is discharged to the outside of the air conditioning chamber.

As described above, the drip trays 17A and 17B for guiding the effluent are located in the air passage 18 through which the air cooled by the heat exchanger 7 passes, so the drip trays are free from dewing. . In addition, the rear drain pan 9B does not require an external drainage hole as in the prior art in which external air can be introduced into the air-conditioning chamber. As a result, there is no possibility of introducing outside air into the heat exchanger through the drain, and there is no phenomenon such as dew formation.

Since the front and rear drain pans 9A and 9B are formed inside the rear panel 3 and have no couplings, they can be attached to the blowing fan system including the blower fan 11, the noise, etc. accurately, It is possible to make indoor units free of noise that can be generated.

Since the first and second drip trays 17A and 17B are located at opposite side ends of the blower 18, they do not significantly affect the fan performance, and the blowing of the indoor blower fan 11 is carried to the drip trays. Does not significantly affect the runoff collected.

Although the air in the rear drain pan 9B cannot be prevented from entering the drips 17a, 17b through the drain 27, the air is cooled by the effluent because the air has already been heat exchanged in the heat exchanger 7. When air contacts the drip trays 17a and 17b, it hardly condenses into water droplets.

The space formed by the first and second drip trays 17A and 17B is sealed by the first and second cover members 23A and 23B, respectively. This structure can completely prevent the inflow of dust into the drip tray, thereby preventing the drip block from being blocked by the dust.

A pipe section 29 of rectangular cross section is provided on each vertical portion 28b of the drip trays 17A and 17B. If an inverted U-shaped cross-section member is provided on the vertical portion 28b to seal the space defined by the vertical portion 28b, the effluent will leak out through the clearance formed between them. The pipe portion 29 seals the space formed by the vertical portion 28b so that a clearance is not formed therebetween. As a result, the outflow water does not leak out or flow into the vertical portion 28b from the outside.

Since the first and second cover members 23A and 23B overlap each other through the end plates 12b and 12c of the cross flow fan 12, air leakage of the air passage 18 is prevented through the end plates 12b and 12c. It can minimize, and can suppress the fall of blower fan performance by this.

The motor holding member 21 can be rotated about the hinge 30 away from the rear panel 3 to facilitate maintenance work such as cleaning, replacing, etc. of the cross flow fan 12.

It is necessary to remove the motor holding member 21 to perform maintenance work. However, at this time, the first cover member 23A should be fixed and maintained in the first drip tray 17A.

For this reason, the motor holding member 21 is engaged with the first cover member 23A by the hinge 30 so that the movement of the motor holding member 21 does not affect the first cover member 23A. Furthermore, since the cover member 23A and the motor holding member 21 are integrally formed with each other, the number of components and the required cost can be reduced.

Since the bearing base 22 is coupled with the second cover member 23B by the string part 39 which is more flexible and thinner than the hinge 30, the bearing base 22 is a cover member fixed to the drip tray 17B. It can be easily moved back and forth and from side to side with respect to the rear panel 3 with 23B. This can facilitate maintenance work such as cleaning and replacing the cross flow fan 12.

It is necessary to remove the bearing base 22 to perform maintenance work. However, at this time, the second cover member 23B must be fixed and maintained in the second drip tray 17B.

For this reason, the bearing base 22 is coupled with the 2nd cover member 23B by the string part 29, and the movement of the bearing base 22 does not affect the 2nd cover member 23B. Furthermore, since the cover member 23B and the bearing base 22 are integrally formed with each other, the number of components and the required cost can be reduced.

The rib 91A constituting the front drain pan 9A and the rib 91B constituting the rear drain pan 9B extend in the same direction at the same angle.

In order to integrally form the front and rear drain pans 9A and 9B with the rear panel 3, injection molding is performed using molds 90A-90E as shown in FIG. Since the ribs 91A, 91B extend in the same direction at the same angle, the molds for forming the front and rear drain pans 9A, 9B are removed in the same direction.

This means in particular the mold 90A contained in the molds 90A-90E for injection molding the rear panel 3 can be used to mold both the front and rear drain pans 9A, 9B for cost reduction.

Although the first and second drip trays 17A and 17B are configured as recesses having a U-shaped cross section in the above-described embodiment, they are not limited to the above structure and may be changed as follows.

Since the first and second troughs are symmetrical to each other, only one description will be given.

The trough according to the second embodiment of the present invention is shown in FIG. The drip tray 50 includes a first wall portion 51 positioned away from the air passage 18, a second wall portion 52 positioned near the air passage 18, and a third wall portion 53 positioned between the wall portions. And plate members 54 that connect these wall portions with each other. Accordingly, the drip tray 50 has a substantially E-shaped cross section to increase the strength of the member formed of synthetic resin. The drip tray 50 includes the first to third wall portions 51-53 and a plate member 54 connecting them with high strength. The first and third wall portions 51 and 53 and the plate member 54 cooperate with the passage P so that the outflow water W flows.

Opposite ends of the passage P communicate with the rear drain pan 9B and the front drain pan 9A, respectively, and one of the opposing ends close to the rear drain pan 9B is the second and third wall portions 52, 53. It is sealed by the drain pan 9B between.

The third wall portion 53 is lower than the second wall portion 52.
