Detailed Description
Next, an indoor unit of an air conditioner according to the present invention will be described in detail with reference to the illustrated embodiments.
[ first embodiment ]
Fig. 1 is a perspective view of an indoor unit of an air conditioner according to a first embodiment of the present invention, as viewed obliquely from below. The indoor unit is a ceiling-embedded indoor unit.

An air outlet 10 through which the blown air is blown out downward is provided along the short side of the panel 2 on one of the longitudinal directions of the panel 2 and on the lower surface of the panel 2. Further, a shutter 20 is rotatably attached to the panel 2. Fig. 1 shows a state in which the blowout port 10 is closed by the baffle 20.

Refrigerant pipes (not shown) are connected to the pipe connection portions 5 and 6 from the outside.
In fig. 1, 8 denotes an electric component part, and 101 to 103 are hanging metal fittings provided so as to protrude laterally from the housing main body 1.
Fig. 2 is a perspective view of the indoor unit as viewed obliquely from above, and in fig. 2, the same components as in fig. 1 are denoted by the same reference numerals.
Fig. 3 is a bottom view of the indoor unit. In fig. 3, the same components as those in fig. 1 are denoted by the same reference numerals.
As shown in fig. 3, a suction port 1a is provided in the central portion of the housing main body 1. A filter 4 (shown in fig. 4) is attached between the suction port 1a and the grill 3.
Fig. 4 shows a cross-sectional view taken along line IV-IV in fig. 3, and in fig. 4, the same reference numerals are assigned to the same components as those in fig. 1 to 3.
As shown in fig. 4, a vortex fan 30 driven by a motor 31 is disposed in the casing main body 1. A bell mouth 32 is disposed between the suction port 1a of the casing main body 1 and the vortex fan 30. Further, a heat exchanger 40 and a partition plate 50 are disposed in the casing main body 1 and around the vortex fan 30. Further, a drain pan 60 is disposed in the casing main body 1 below the heat exchanger 40 and the partition plate 50. Further, a heat insulating member 61 is disposed in the casing main body 1 so as to cover the side surface and the bottom surface of the drain pan 60. A portion 61a of the heat insulating member 61 on the side facing the wind passage P protrudes toward the wind passage P1 side (see fig. 8).
The vortex fan 30 is an example of a centrifugal fan. The partition plate 50 is an example of a partition portion. In addition, the partition portion may be formed integrally with the housing.
Further, a ventilation passage P for guiding the blown air from the vortex fan 30 to the blow-out port 10 of the panel 2 is formed in the casing main body 1.
Fig. 5 is a bottom view of the indoor unit with the panel 2, the drain pan 60, and the like removed.
As shown in fig. 5, the housing main body 1 includes: a first wall 11 on the side of the outlet 10 (shown in fig. 10); a second wall portion 12 facing the first wall portion 11; and a third wall portion 13 and a fourth wall portion 14 that are provided between the first wall portion 11 and the second wall portion 12 so as to face each other. In fig. 5, 10a is a first blowout port portion, and 10b is a second blowout port portion.
The heat exchanger 40 includes, in a plan view: the first heat exchange portion 41; a second heat exchange portion 42 located on an upstream side in a rotation direction (arrow R1) of the vortex fan 30 with respect to the first heat exchange portion 41; and a third heat exchange portion 43 located on a downstream side in the rotational direction (arrow R1) of the vortex fan 30 with respect to the first heat exchange portion 41.
Both ends of the heat exchanger 40 are connected to each other via an arc-shaped partition plate 50, and the vortex fan 30 is surrounded by the heat exchanger 40 and the partition plate 50. The partition plate 50 bulges outward.
The pipe connecting portions 5 and 6 are connected to the ends of the third heat exchanging portion 43 of the heat exchanger 40. Further, a drain pump 70 is disposed in the casing main body 1 on the third wall portion 13 side between the partition plate 50 and the second wall portion 12.
Further, by making the third heat exchange portion 43 located on the downstream side in the rotational direction (arrow R1) of the vortex fan 30 of the first heat exchange portion 41 of the heat exchanger 40 shorter than the second heat exchange portion 42 located on the upstream side in the rotational direction (arrow R1) of the vortex fan 30 of the first heat exchange portion 41, a space for piping connected to the piping connection portions 5, 6 can be secured in the case main body 1 at the end portion of the third heat exchange portion 43. Further, compared to the case where the second heat exchange portion 42 and the third heat exchange portion 43 have the same length, the gap between the end portion on the downstream side of the partition plate 50 and the outer periphery of the vortex fan 30 can be made wider than the gap between the end portion on the upstream side of the partition plate 50 and the outer periphery of the vortex fan 30.
Further, by providing the outlet 10 on the opposite side of the partition plate 50 with respect to the heat exchanger 40 of the panel 2, the air blown out from the vortex fan 30 can be smoothly blown out from the outlet 10 through the heat exchanger 40.
Fig. 6 shows the position of the center O1 of the vortex fan 30 of the indoor unit, and the center O1 of the vortex fan 30 is located on the upstream side (left side of the vertical bisector L2 in fig. 6) in the airflow direction (arrow R2) between the vortex fan 30 and the partition plate 50 with respect to the vertical bisector L2 of the line segment L1 connecting both ends of the partition plate 50.
Accordingly, the gap between the downstream end of the partition plate 50 covering the opening of the heat exchanger 40 and the outer periphery of the vortex fan 30 is wider than the gap between the upstream end of the partition plate 50 and the outer periphery of the vortex fan 30, and the pressure in the vicinity of the downstream end of the partition plate 50 where a large abnormal sound is generated is reduced, so that the pressure of the high-pressure portion generated in the end of the partition plate 50 covering the opening of the heat exchanger 40 can be reduced, and the generation of the abnormal sound can be suppressed.
The inventors conducted a simulation experiment under the condition that the center O1 of the vortex fan 30 is located on the upstream side in the airflow direction (R2) between the vortex fan 30 and the partition plate 50 with respect to the perpendicular bisector L2 of the line segment L1 connecting both ends of the partition plate 50. As can be confirmed by the simulation, the pressure in the vicinity of the downstream end of the partition plate 50 is reduced, and the pressure in the high-pressure portion generated at the end of the partition plate 50 covering the opening of the heat exchanger 40 is reduced, thereby suppressing the generation of abnormal sound.
As shown in fig. 6, in a plan view, the partition plate 50 projects outward beyond a line segment L1 connecting both ends of the partition plate 50 (partition portion), and a part of the vortex fan 30 overlaps with a region surrounded by a line segment L1 connecting both ends of the partition plate 50 (partition portion) and the partition plate 50, so that the vortex fan 30 rotates along the partition plate 50 curved so as to project outward, and the partition plate 50 can smoothly guide the blown air from the vortex fan 30 and reduce the storage space in the casing main body 1.
The position of the center O1 of the vortex fan 30 is set as shown in fig. 7. The heat exchanger 40 has a heat exchange portion 40a (hatched area shown in fig. 7) having a line-symmetric shape in plan view. The vortex fan 30 is disposed such that the center O1 of the vortex fan 30 is located on the upstream side (the left side of the axis of symmetry L3 in fig. 7) in the airflow direction (arrow R2) between the vortex fan 30 and the partition plate 50 with respect to the axis of symmetry L3 of the heat exchange portion 40a having the line-symmetric shape.
Here, regarding the positional relationship between the heat exchanger 40 and the casing main body 1, it is preferable that the heat exchanger 40 is disposed in the casing main body 1 as follows: the axis of symmetry L3 of the line-symmetric heat exchange portion 40a of the heat exchanger 40 is aligned with the longitudinal center line of the housing main body 1.
Fig. 8 is a bottom view showing the indoor unit with the front panel 2 removed, and in fig. 8, the same components as those in fig. 1 to 5 are denoted by the same reference numerals. Note that 61 is a heat insulating member covering the side surface and the bottom surface of the drain pan 60 (shown in fig. 4), and 61a is a portion of the heat insulating member 61 protruding toward the wind path P1 side.
As shown in fig. 8, a portion of the air passage P from the heat exchanger 40 to the air outlet 10 in the casing main body 1 on the downstream side of the upper end of the drain pan 60 is formed in a cross-sectional shape having a first air passage area Aa along one side of the casing main body 1 and a second air passage area Ab extending from both end portions of the first air passage area Aa toward the second wall portion 12 (hatched area a in fig. 8). Here, the cross-sectional shape of the wind passage P having the first and second wind passage regions Aa and Ab is a horizontal cross-sectional shape along a plane orthogonal to the rotation axis of the vortex fan 30.
Fig. 9 is a bottom view showing a state in which the shutter 20 (indicated by oblique lines) is attached to the indoor unit shown in fig. 5, and fig. 10 is a bottom view showing a state in which the shutter 20 of the indoor unit is removed. In fig. 9 and 10, the same reference numerals are assigned to the same components as those in fig. 1 to 7.
As shown in fig. 9 and 10, the heat exchanger 40 in the shape of コ in plan view includes: a first heat exchange portion 41 arranged in parallel with the first wall portion 11 of the casing main body 1; a second heat exchange portion 42 connected to one end of the first heat exchange portion 41; and a third heat exchange portion 43 connected to the other end of the first heat exchange portion 41.
The second heat exchange portion 42 is gradually spaced from the third wall portion 13 from the first heat exchange portion 41 toward the distal end. Further, the third heat exchange portion 43 gradually narrows in interval with the fourth wall portion 14 from the first heat exchange portion 41 side toward the distal end side. That is, the interval between the second heat exchange portion 42 and the third heat exchange portion 43 of the heat exchanger 40 gradually becomes wider toward both ends.
As shown in fig. 9, the damper 20 that controls the wind direction of the blown air from the air outlet 10 includes: a baffle main body 20a provided along the first wall portion 11 of the housing main body 1; and auxiliary baffle plates 20b extending from both end portions of the baffle plate main body 20a toward the second wall portion 12 side of the housing main body 1.
As shown in fig. 10, the air outlet 10 includes: a rectangular first blowout port portion 10a provided along the first wall portion 11 (shown in fig. 9) of the casing main body 1; and second purge port portions 10b extending from both end portions of the first purge port portion 10a toward the second wall portion 12 (shown in fig. 9) of the casing main body 1. Here, the air outlet 10 is a hatched area in fig. 10, and is an area where the air passage P is visible when viewed from a direction perpendicular to the panel 2.
The direction of the blown air blown out from the first outlet port portion 10a can be controlled by the baffle main body 20a provided along one side of the casing main body 1, and the direction of the blown air blown out from the second outlet port portion 10b can be controlled by the auxiliary baffles 20b extending from both end portions of the baffle main body 20a to the side opposite to the one side of the casing main body 1.
Fig. 11 shows the relationship between the outside areas S1, S2 of the curved portion of the heat exchanger 40 of the indoor unit and the air outlet 10.
As shown in fig. 11, the area S1 overlaps a part of the second outlet port portion 10b of the outlet port 10 in plan view, and the area S1 is surrounded by a first plane including a tangent F1 of the first heat exchange portion 41 parallel to the longitudinal direction of the first outlet port portion 10a, a second plane including a tangent F2 of the second heat exchange portion 42 excluding a portion connected to the first heat exchange portion 41, and the outer side surface of the heat exchanger 40. In addition, the area S2 overlaps a part of the second outlet port 10b of the air outlet 10 in plan view, and the area S2 is surrounded by a first plane including a tangent F1 of the first heat exchange portion 41 parallel to the longitudinal direction of the first outlet port 10a, a third plane including a tangent F3 of the third heat exchange portion 43 excluding the outer surface of the portion connected to the first heat exchange portion 41, and the outer surface of the heat exchanger 40.
Thus, an empty space available for the second blowout part 10b can be secured outside the connection portion between the first heat exchange part 41 and the second heat exchange part 42 and the connection portion between the first heat exchange part 41 and the third heat exchange part 43.
Further, by forming the air outlet portion in such a shape that the distance between the second air outlet portions 10b gradually becomes wider from the first air outlet portion 10a side toward the tip end portion, the space formed in the casing main body 1 can be effectively used for the second air outlet portions 10b by the curved portion of the コ -shaped heat exchanger 40.
In the first embodiment, the first plane including the tangent line F1 parallel to the longitudinal direction of the first outlet port portion 10a of the first heat exchange portion 41 of the コ -shaped heat exchanger 40 is used, but even when the first outlet port portion is curved rather than rectangular, the direction of the tangent line to the central portion of the first outlet port portion is the longitudinal direction of the first outlet port portion.
Fig. 12 shows a relationship between the heat exchanger 40 and the air outlet 10 when the indoor unit is viewed from the side (X direction). In fig. 12, the same components as those in fig. 5 are denoted by the same reference numerals. Further, X is a direction viewed from the side of the second wall portion 12 side, and Y is a direction viewed from the side of the third wall portion 13 side.
As shown in fig. 12, when viewed from the side in the direction (X direction) opposite to the outlet port 10 with respect to the vortex fan 30, the regions S3, S4 of the second and third heat exchange portions 42, 43 overlap the second outlet port portion 10b of the outlet port 10, and the space in the casing main body 1 can be effectively used. In addition, all of the second and third heat exchange portions 42 and 43 may not overlap the second outlet port portion 10b of the outlet port 10.
Fig. 13 shows a relationship between the heat exchanger 40 and the air outlet 10 when the indoor unit is viewed from the side (Y direction). In fig. 13, the same components as those in fig. 5 are denoted by the same reference numerals. Further, X is a direction viewed from the side of the second wall portion 12 side, and Y is a direction viewed from the side of the third wall portion 13 side.
As shown in fig. 13, when viewed from the side in one direction (Y direction) in the extending direction of the first outlet port portion 10a of the outlet port 10, the area S5 of the heat exchanger 40 overlaps with the second outlet port portion 10b of the outlet port 10, and the space in the casing main body 1 can be effectively used.
Fig. 14 shows the width W2 of the heat exchanger 40 and the width W1 of the air outlet 10 when the indoor unit is viewed from the side (X direction). In fig. 14, the same components as those in fig. 5 are denoted by the same reference numerals. Further, X is a direction viewed from the side of the second wall portion 12 side, and Y is a direction viewed from the side of the third wall portion 13 side.
As shown in fig. 14, when viewed from the side in the direction (X direction) opposite to the air outlet 10 with respect to the vortex fan 30, the width W1 of the air outlet 10 is larger than the width W2 of the heat exchanger 40, and the air outlet area can be further enlarged.
According to the indoor unit configured as described above, by disposing the heat exchanger 40 in the casing main body 1 so as to surround three sides of the vortex fan 30 (centrifugal fan) and making the downstream side of the air passage P from the heat exchanger 40 to the air outlet 10 have the cross-sectional shape having the first air passage area Aa along one side of the casing main body 1 and the second air passage area Ab extending from both ends of the first air passage area Aa toward the partition portion 50 side, the cross-sectional area of the air passage P can be enlarged with a simple configuration to reduce the pressure loss of the air passage P, and the performance can be improved.
Further, by forming the portion of the wind passage P downstream of the upper end of the drain pan 60 into a cross-sectional shape having the first wind passage area Aa and the second wind passage area Ab, the pressure loss can be effectively reduced by enlarging the portion of the wind passage P having a narrow flow path cross-sectional area.
In the first embodiment, the portion of the air passage P on the downstream side of the upper end of the drain pan 60 is formed into an コ -shaped cross section having the first air passage area Aa and the second air passage area Ab, but at least a portion of the downstream side of the air passage from the heat exchanger to the air outlet in the housing may be formed into a コ -shaped cross section having the first air passage area along one side of the housing and the second air passage area extending from both ends of the first air passage area toward the partition portion side.
Further, since the air outlet 10 includes the first air outlet portion 10a provided along one side of the casing main body 1 and the second air outlet portion 10b provided so as to extend from both ends of the first air outlet portion 10a toward the partition plate 50 side, the area of the air outlet 10 can be increased, the pressure loss at the air outlet portion can be reduced, and the performance can be further improved.
Further, by gradually narrowing the distance between the facing sides of the casing main body 1 and the second and third heat exchange portions 42 and 43 extending from the opposite ends of the first heat exchange portion 41 facing the air outlet 10 from the first heat exchange portion 41 side toward the distal end side, the opening side between the opposite ends of the コ -shaped heat exchanger 40 is opened, and the connecting portion between the first heat exchange portion 41 and the second heat exchange portion 42 and the connecting portion between the first heat exchange portion 41 and the third heat exchange portion 43 are brought closer to the inside of the casing main body 1, whereby the area of the air outlet 10 can be enlarged by using the empty space for the second air outlet 10 b.
In the first embodiment, the vortex fan 30 is used as the centrifugal fan, but another centrifugal fan such as a sirocco fan may be used.
