Problems to be solved by the invention
According to the above-described conventional indoor unit of an air conditioner, since the center of the vortex fan is located on the center line of the heat exchanger and the casing main body and the heat exchanger and the partition portion have a bilaterally symmetrical shape, there is a problem in that: although the rotational direction of the vortex fan is one direction, since the air flow is different from the left to the right, a high pressure portion is generated in the partition portion to generate an abnormal sound.
Therefore, an object of the present invention is to provide an indoor unit of an air conditioner capable of reducing the pressure of a high-pressure portion generated at an end portion of a partition portion covering an opening portion of a heat exchanger and suppressing generation of abnormal sound.
Means for solving the problems
An indoor unit of an air conditioner according to an aspect of the present invention is an indoor unit of an air conditioner including:
a housing;
a centrifugal fan disposed in the housing and rotating in a predetermined rotational direction;
a heat exchanger disposed inside the casing and around the centrifugal fan; and
a partition portion connecting both ends of the heat exchanger and surrounding the centrifugal fan together with the heat exchanger,
the center of the centrifugal fan is located on the upstream side in the airflow direction between the centrifugal fan and the partition with respect to a perpendicular bisector of a line segment connecting both ends of the partition.
According to the above configuration, since the center of the centrifugal fan rotating in the predetermined rotation direction is located on the upstream side in the airflow direction between the centrifugal fan and the partition with respect to the perpendicular bisector of the line segment connecting the both ends of the partition, the gap between the downstream-side end of the partition covering the opening of the heat exchanger and the outer periphery of the centrifugal fan is wider than the gap between the upstream-side end and the outer periphery of the centrifugal fan. Accordingly, the pressure in the vicinity of the downstream end of the partition portion where a large abnormal sound is generated is reduced, and therefore, the pressure of the high-pressure portion generated at the end of the partition portion covering the opening of the heat exchanger can be reduced, and the generation of the abnormal sound can be suppressed.
In addition, in the indoor unit of an air conditioner of one embodiment,
an air outlet is provided on a side of the casing opposite to the partition portion with respect to the heat exchanger.
According to the above-described embodiment, by providing the air outlet on the opposite side of the casing from the partition portion with respect to the heat exchanger, the air blown out from the centrifugal fan can be smoothly blown out from the air outlet through the heat exchanger.
In addition, in the indoor unit of an air conditioner of one embodiment,
the partition portion bulges outward than a line segment connecting both ends of the partition portion when viewed from above,
a part of the centrifugal fan overlaps a region surrounded by the segment connecting both ends of the partition and the partition.
According to the above embodiment, the partition portion bulges outward beyond the line segment connecting the both ends of the partition portion in a plan view, and a part of the centrifugal fan overlaps the region surrounded by the line segment connecting the both ends of the partition portion and the partition portion, whereby the centrifugal fan rotates along the partition portion curved so as to bulge outward, and the partition portion can smoothly guide the blown air from the centrifugal fan and can reduce the storage space in the casing.
In addition, in the indoor unit of an air conditioner of one embodiment,
the heat exchanger has, in a plan view: a first heat exchange unit; a second heat exchange portion located on an upstream side of the first heat exchange portion in a rotation direction of the centrifugal fan; and a third heat exchange portion located on a downstream side of the first heat exchange portion in a rotation direction of the centrifugal fan,
the third heat exchange portion is shorter than the second heat exchange portion.
According to the above embodiment, the third heat exchange portion located on the downstream side in the rotation direction of the centrifugal fan of the first heat exchange portion is made shorter than the second heat exchange portion located on the upstream side in the rotation direction of the centrifugal fan of the first heat exchange portion, whereby the pipe connection portion is provided at the end portion of the third heat exchange portion, and a space for connecting the pipe can be secured in the housing. Further, compared to the case where the second heat exchange portion and the third heat exchange portion have the same length, the gap between the end portion on the downstream side of the partition portion and the outer periphery of the centrifugal fan can be made wider than the gap between the end portion on the upstream side of the partition portion and the outer periphery of the centrifugal fan.
Effects of the invention
As described above, according to the present invention, the center of the centrifugal fan rotating in the predetermined rotation direction is located on the upstream side in the airflow direction between the centrifugal fan and the partition with respect to the perpendicular bisector of the line segment connecting the two ends of the partition, and thus the pressure of the high-pressure portion generated at the end of the partition covering the opening of the heat exchanger can be reduced and the generation of abnormal sound can be suppressed.

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. 9); 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.
The heat exchanger 40 includes, in a plan view: the first heat exchange portion 41; a second heat exchange portion 42 located on the upstream side of the first heat exchange portion 41 in the rotational direction (arrow R1) of the vortex fan 30; and a third heat exchange portion 43 located on the downstream side of the first heat exchange portion 41 in the rotational direction (arrow R1) of the vortex fan 30.
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.
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.
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 shows a state in which the flap 20 (indicated by oblique lines) is attached to the indoor unit shown in fig. 5, and fig. 9 shows a state in which the flap 20 of the indoor unit is detached. In fig. 8 and 9, the same reference numerals are assigned to the same components as those in fig. 1 to 7.
As shown in fig. 8 and 9, 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 air outlet 10 includes: a rectangular first blowout port portion 10a provided along the first wall portion 11 (shown in fig. 8) 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. 8) of the casing main body 1.
As shown in fig. 8, the damper 20 that controls the wind direction of the blown air from the air outlet 10 includes: a shutter main body 20a provided along the first wall portion 11 of the casing 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.
According to the indoor unit configured as described above, the center O1 of the vortex fan 30 (centrifugal fan) that rotates in the predetermined rotation direction (R1) 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 that connects the two ends of the partition plate 50 (partition), and thus the gap between the end portion on the downstream side of the partition plate 50 that covers the opening of the heat exchanger 40 and the outer periphery of the vortex fan 30 is 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. Accordingly, the pressure in the vicinity of the downstream end of the partition plate 50 where a large abnormal sound is generated is reduced, and therefore, the pressure of the high-pressure portion generated at 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. Through this simulation experiment, it was confirmed that the pressure in the vicinity of the downstream end of the partition plate 50 was reduced, the pressure in the high-pressure portion generated at the end of the partition plate 50 covering the opening of the heat exchanger 40 was reduced, and the generation of abnormal sound was suppressed.
Fig. 10 shows a pressure distribution obtained by a simulation experiment of the indoor unit according to the first embodiment. Fig. 11 shows a pressure distribution as viewed from line XI-XI in fig. 10. As shown in fig. 10 and 11, the pressure of the high-pressure portion generated in the vicinity of the end portion on the downstream side of the partition plate 50 covering the opening of the heat exchanger 40 is reduced.
Further, by providing the outlet 10 on the side of the panel 2 opposite to the partition plate 50 with respect to the heat exchanger 40, the air blown out from the vortex fan 30 can be smoothly blown out from the outlet 10 through the heat exchanger 40.
As shown in fig. 6, in a plan view, the partition plate 50 bulges 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 a region surrounded by a line segment L1 connecting both ends of the partition plate 50 (partition portion) and the partition plate 50, whereby the vortex fan 30 rotates along the partition plate 50 curved so as to bulge outward, and the partition plate 50 can smoothly guide the blown air from the vortex fan 30 and can reduce the storage space in the case main body 1.
Further, by making the third heat exchange portion 43 located on the downstream side in the rotation direction 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 rotation direction of the vortex fan 30 of the first heat exchange portion 41, the pipe connection portions 5 and 6 can be provided at the end portions of the third heat exchange portion 43, and a space for connecting pipes can be secured in the housing main body 1. 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.
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.
