Disclosure of Invention
Problems to be solved by the invention
In the above-described conventional indoor unit of an air conditioner, since one wall portion of the casing is formed so that a distance between both ends of the first and second heat exchange portions is constant, there is a problem in that: the distance between the wall portion and the other wall portion on the opposite side of the housing from the wall portion cannot be reduced, and the housing cannot be downsized.
accordingly, an object of the present invention is to provide an indoor unit of an air conditioner capable of miniaturizing a casing.
means for solving the problems
an indoor unit of an air conditioner according to an aspect of the present invention includes:
A housing having first and second wall portions facing each other, and third and fourth wall portions provided between the first wall portion and the second wall portion and facing each other;
A centrifugal fan disposed within the housing; and
A heat exchanger disposed between the centrifugal fan and the first, third, and fourth wall portions of the casing,
The heat exchanger has:
a first extending portion located on the third wall portion side of the housing, extending from the first wall portion side toward the second wall portion side of the housing; and
A second extending portion located on the fourth wall portion side of the housing, extending from the first wall portion side toward the second wall portion side of the housing,
An end of the first extension of the heat exchanger is located closer to the second wall portion side of the housing than an end of the second extension of the heat exchanger.
According to the above configuration, since the end of the first extending portion of the heat exchanger is positioned closer to the second wall portion side of the housing than the end of the second extending portion of the heat exchanger, the end of the second extending portion of the heat exchanger is positioned closer to the first wall portion side of the housing than the end of the first extending portion of the heat exchanger. Therefore, for example, the portion of the second wall portion of the housing on the second extending portion side can be recessed toward the first wall portion side of the housing. Further, for example, a portion of the fourth wall portion of the housing on the distal end side of the second extending portion may be recessed toward the first wall portion side of the housing. Therefore, the housing can be miniaturized.
According to an indoor unit of an air conditioner of one embodiment,
A refrigerant pipe connection portion to which a refrigerant pipe is connected is provided in a portion of the second wall portion of the housing on the second extending portion side.
According to the above embodiment, the portion of the second wall portion of the housing on the second extending portion side can be recessed toward the first wall portion side of the housing. Therefore, by providing the refrigerant pipe connection portion connected to the refrigerant pipe at the portion of the second wall portion of the housing on the second extending portion side, the refrigerant pipe connection portion can be prevented from protruding more outward (on the side opposite to the first wall portion) than the other portion of the second wall portion of the housing.
according to an indoor unit of an air conditioner of one embodiment,
A refrigerant pipe connection portion to which a refrigerant pipe is connected is provided in a portion of the fourth wall portion of the housing on a distal end side of the second extending portion.
According to the above embodiment, the portion of the fourth wall portion of the housing on the distal end side of the second extending portion can be recessed toward the third wall portion side of the housing. Therefore, by providing the refrigerant pipe connection portion to be connected to the refrigerant pipe at the portion of the fourth wall portion of the housing on the distal end side of the second extending portion, the refrigerant pipe connection portion can be prevented from protruding more outward (on the side opposite to the third wall portion) than the other portion of the fourth wall portion of the housing.
According to an indoor unit of an air conditioner of one embodiment,
a drain pump is disposed between a portion of the second wall portion of the casing on the first extending portion side and a tip end of the first extending portion of the heat exchanger.
according to the above embodiment, the drain pump may be disposed between the portion of the second wall portion of the casing on the side of the first extending portion and the end of the first extending portion of the heat exchanger, so that the drain pump is not disposed outside the casing. Therefore, an increase in the required space around the housing can be prevented.
An indoor unit of an air conditioner according to one embodiment includes a partition portion that surrounds a centrifugal fan together with the heat exchanger, and that connects a distal end of the first extension portion of the heat exchanger and a distal end of the second extension portion of the heat exchanger.
according to the above embodiment, the partition connects the end of the first extension of the heat exchanger and the end of the second extension of the heat exchanger, so that the air blown by the centrifugal fan can flow to the first and second extensions, and the heat exchange efficiency between the air blown by the centrifugal fan and the first and second extensions can be improved.
effects of the invention
The invention can provide an indoor unit of an air conditioner, which can miniaturize a casing.

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. Fig. 2 is a perspective view of the indoor unit as viewed from obliquely above.
the indoor unit of the present embodiment is a ceiling-embedded indoor unit, and as shown in fig. 1 and 2, includes: a housing main body 1; a rectangular panel 2 attached to a lower side of the case main body 1; and a grill 3 detachably attached to the panel 2. The housing main body 1, the panel 2, and the grill 3 constitute an example of a housing.
The pipe connecting portions 5 and 6 and the drain cover 7 protrude from the side wall of the housing body 1. Refrigerant pipes (not shown) are connected to the pipe connection portions 5 and 6 from the outside of the housing body 1. A drain hose (not shown) is connected to the drain cover 7 from the outside of the housing body 1.
Further, an electric component part 8 is provided on the side wall of the housing main body 1 so as to be adjacent to the pipe connection parts 5 and 6 and the drain cover 7.
The panel 2 is provided with an air outlet 10 located on one side in the longitudinal direction of the grill 3 and along the short side of the outer edge of the panel 2. Further, a flap 20 that opens and closes the air outlet 10 is rotatably attached to the panel 2. Fig. 1 shows a state in which the blowout port 10 is closed by the baffle 20.
The indoor unit according to the first embodiment includes suspension fittings 101, 102, 103, and 104 (the suspension fitting 104 is shown in fig. 5). The suspension fittings 101, 102, 103, and 104 are fixed to, for example, suspension bolts (not shown) hanging from the main structure in the ceiling. Thereby, the indoor unit is suspended from the ceiling.
fig. 3 shows a bottom view of the indoor unit. In fig. 3, the same components as those in fig. 1 and 2 are denoted by the same reference numerals as those in fig. 1 and 2.
The air outlet 10 is an opening in the shape of コ when viewed from below. More specifically, the air outlet 10 has a shape along one short side of the outer edge of the panel 2 and two long sides of the outer edge of the panel 2. The baffle 20 is formed in an コ -shape when viewed from below when the outlet 10 is closed.
Further, a suction port 1a is provided in a central portion of the housing main body 1 (shown in fig. 1 and 2). A filter 4 (shown in fig. 4) is disposed between the suction port 1a and the grill 3.
Fig. 4 shows a cross-sectional view from the line IV-IV of fig. 3. In fig. 4, the same components as those in fig. 1 to 3 are denoted by the same reference numerals as those in fig. 1 to 3.
a vortex fan 30 is disposed in the casing main body 1. The vortex fan 30 is driven by a motor 31 to rotate in a predetermined rotational direction. Here, when the vortex fan 30 is viewed from below, the predetermined rotational direction coincides with the counterclockwise direction. The vortex fan 30 is an example of a centrifugal fan.
A bell mouth 32 is disposed between the suction port 1a of the casing main body 1 and the vortex fan 30. The vortex fan 30 sucks in indoor air through a space inside the bell mouth 32.
further, in the casing main body 1, a heat exchanger 40 and a partition plate 50 are disposed around the vortex fan 30. The air blown out by the vortex fan 30 flows through the heat exchanger 40 toward the air outlet 10. At this time, the partition plate 50 guides the air blown out of the vortex fan 30 to the heat exchanger 40. The partition plate 50 is an example of a partition portion. The partition may be formed by a part of the housing main body 1.
Further, a drain pan 60 is disposed from the lower side of the heat exchanger 40 to the lower side of the partition plate 50 in the casing main body 1. This allows the drain pan 60 to receive the dew condensation water generated in the heat exchanger 40 and the partition plate 50.
further, a ventilation path 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 6, and the like removed.
The housing main body 1 has: a first wall 11 on the side of the outlet 10; a second wall portion 12 facing the first wall portion 11; and third and fourth wall portions 13 and 14 provided between the first wall portion 11 and the second wall portion 12 so as to face each other. The end portions of the third and fourth wall portions 13 and 14 on the side of the outlet 10 are connected to the first wall portion 11. On the other hand, the end portions of the third and fourth wall portions 13 and 14 opposite to the air outlet 10 are connected to the second wall portion 12.
Further, the second wall portion 12 is shaped so that the portion 12b on the fourth wall portion 14 side is closer to the first wall portion 11 side than the portion 12a on the third wall portion 13 side. That is, the portion 12b of the second wall 12 where the pipe connecting portions 5 and 6 are provided is recessed toward the first wall 11. Further, an intermediate portion 12c between the portions 12a, 12b is inclined with respect to the direction in which the portions 12a, 12b extend. The portion 12a of the second wall portion 12 on the third wall portion 13 side is an example of the portion of the second wall portion of the housing on the first extending portion side. The portion 12b of the second wall portion 12 on the fourth wall portion 14 side is an example of the portion of the second wall portion of the housing on the second extending portion side.
The heat exchanger 40 is disposed between the first wall 11, the third wall 13, and the fourth wall 14 of the casing main body 1 and the vortex fan 30.
More specifically, the heat exchanger 40 has a first heat exchange portion 41, a second heat exchange portion 42, and a third heat exchange portion 43. The first heat exchange portion 41, the second heat exchange portion 42, and the third heat exchange portion 43 are integrally formed with each other. The second heat exchange portion 42 is an example of the first extension portion. The third heat exchange portion 43 is an example of the second extension portion. The first heat exchange portion 41, the second heat exchange portion 42, and the third heat exchange portion 43 may be formed separately and arranged with a space therebetween, for example.
the first heat exchange portion 41 is formed along the first wall portion 11, and faces the first wall portion 11 of the casing main body 1.
The second heat exchange portion 42 faces the third wall portion 13 of the housing main body 1, and extends from the first wall portion 11 side toward the second wall portion 12 side. The second heat exchange portion 42 is located upstream of the first heat exchange portion 41 in the rotation direction of the vortex fan 30. Further, a drain pump 70 is disposed between the end of the second heat exchange portion 42 and the portion of the second wall portion 12 on the third wall portion 13 side.
the drain pump 70 sucks in the dew condensation water or the like accumulated in the drain pan 60, and discharges the sucked dew condensation water or the like to the drain pipe cover 7 side. That is, the drain pump 70 is a pump for discharging dew condensation water and the like in the casing main body 1 to the outside of the casing main body 1.
The third heat exchange portion 43 faces the fourth wall portion 14 of the casing main body 1, and extends from the first wall portion 11 side toward the second wall portion 12 side. The third heat exchange portion 43 is located on the downstream side of the first heat exchange portion 41 in the rotation direction of the vortex fan 30. The end of the second heat exchange portion 42 is closer to the second wall portion 12 than the end of the third heat exchange portion 43. In other words, the distal end of the second heat exchange portion 42 is disposed at a position farther from the air outlet 10, while the distal end of the third heat exchange portion 43 is disposed at a position closer to the air outlet 10.
the end of the third heat exchange portion 43 and the pipe connection portion 5 are connected to each other via a refrigerant pipe 85. The end of the third heat exchange portion 43 and the pipe connection portion 6 are connected to each other via a refrigerant pipe 86.
the pipe connection portions 5 and 6 connect the refrigerant pipes 85 and 86 inside the casing main body 1 and the refrigerant pipes outside the casing main body 1. The refrigerant can be flowed into the heat exchanger 40 by the pipe connection portions 5 and 6.
further, the distance between the second heat exchange portion 42 and the third heat exchange portion 43 becomes longer as it is farther from the blow-out port 10. That is, the heat exchanger 40 is formed in an コ shape in plan view. In addition, the distance between the second heat exchange portion 42 and the third heat exchange portion 43 may be fixed or substantially fixed. The heat exchanger 40 may be formed in a V-shape, circular arc shape, or the like in plan view, for example.
The partition plate 50 surrounds the vortex fan 30 together with the heat exchanger 40. The partition plate 50 connects the end of the second heat exchange portion 42 of the heat exchanger 40 and the end of the third heat exchange portion 43 of the heat exchanger 40.
According to the indoor unit configured as described above, since the end of the second heat exchange portion 42 of the heat exchanger 40 is located closer to the second wall portion 12 of the casing main body 1 than the end of the third heat exchange portion 43 of the heat exchanger 40, the end of the third heat exchange portion 43 of the heat exchanger 40 is located closer to the first wall portion 11 of the casing main body 1 than the end of the second heat exchange portion 42 of the heat exchanger 40. Therefore, the second wall portion 12 of the case main body 1 can be formed into a bent plate shape by recessing the portion 12b of the second wall portion 12 of the case main body 1 on the fourth wall portion 14 side toward the first wall portion 11 of the case main body 1. Therefore, the housing main body 1 can be miniaturized.
further, since the portion 12b of the second wall portion 12 of the housing main body 1 on the fourth wall portion 14 side is recessed toward the first wall portion 11 of the housing main body 1, the product size can be prevented from increasing.
Further, since the refrigerant pipe connection portions 5 and 6 are provided in the portion 12b of the second wall portion 12 of the housing main body 1 on the fourth wall portion 14 side, substantially all of the refrigerant pipe connection portions 5 and 6 can be accommodated in the space adjacent to the portion 12b outside the housing main body 1.
When the refrigerant pipes are connected to the refrigerant pipe connection portions 5 and 6 from the outside of the housing main body 1, a space adjacent to the portion 12b on the outside of the housing main body 1 can be used as a working space for performing a connection operation of the refrigerant pipes.
Further, since the drain pump 70 is disposed between the portion of the second wall portion 12 of the casing main body 1 on the second heat exchange portion 42 side and the end of the second heat exchange portion 42 of the heat exchanger 40, the drain pump 70 does not need to be disposed outside the casing main body 1. Therefore, an increase in the required space around the housing main body 1 can be prevented.
Further, by connecting the end of the second heat exchange portion 42 of the heat exchanger 40 and the end of the third heat exchange portion 43 of the heat exchanger 40 with the partition plate 50, the blown air from the turbofan 30 can be made to flow to the first and third heat exchange portions 43, and the heat exchange efficiency between the blown air of the turbofan 30 and the first and third heat exchange portions 43 can be improved.
[ second embodiment ]
Fig. 6 schematically shows a bottom view of an indoor unit of an air conditioner according to a second embodiment of the present invention. In fig. 6, the indoor unit is in a state where the panel 2, the drain pan 60, and the like are removed. In fig. 6, the same components as those in fig. 5 are denoted by the same reference numerals as those in fig. 5.
The indoor unit according to the second embodiment includes a casing main body 201 having a shape different from that of the casing main body 1 according to the first embodiment. The case main body 201 includes a second wall portion 212 facing the first wall portion 11, and a fourth wall portion 214 provided between the first wall portion 11 and the second wall portion 212 and facing the third wall portion 13. The end portions of the third and fourth wall portions 13 and 214 on the side of the outlet 10 are connected to the first wall portion 11. On the other hand, the end portions of the third and fourth wall portions 13 and 214 on the opposite side from the air outlet 10 are connected to the second wall portion 212.
The fourth wall portion 214 is shaped such that a portion 214b on the second wall portion 212 side is positioned closer to the third wall portion 13 side than a portion 214a on the first wall portion 11 side. That is, the portion 214b of the fourth wall portion 214 where the pipe connecting portions 5 and 6 are provided is recessed toward the third wall portion 13. A portion 214b of the fourth wall portion 214 on the second wall portion 212 side is an example of a portion of the fourth wall portion of the housing on the distal end side of the second extending portion.
the indoor unit having the above-described configuration has the same operational advantages as the indoor unit according to the first embodiment.
further, since the portion 214b of the fourth wall portion 214 of the housing main body 201 on the second wall portion 212 side is recessed toward the third wall portion 13 of the housing main body 201, the product size can be prevented from increasing.
further, since the refrigerant pipe connection portions 5 and 6 are provided in the portion 214b of the fourth wall portion 214 of the housing main body 201 on the second wall portion 212 side, substantially all of the refrigerant pipe connection portions 5 and 6 can be accommodated in the space adjacent to the portion 214b outside the housing main body 201.
when the refrigerant pipes are connected to the refrigerant pipe connection portions 5 and 6 from the outside of the housing main body 201, a space adjacent to the portion 214b on the outside of the housing main body 201 can be used as a working space for performing the connection work of the refrigerant pipes.
In the first and second embodiments, the indoor unit including the casing having a rectangular parallelepiped shape formed by the casing main bodies 1 and 201, the panel 2, and the grill 3 has been described, but the shape of the casing is not limited to this.
In the first and second embodiments, the ceiling-embedded indoor unit has been described, but the indoor unit is not limited thereto, and the present invention may be applied to a ceiling-embedded indoor unit.
In the first and second embodiments, the indoor unit has the air outlet 10 so that the air passing through the heat exchanger 40 is blown out in one direction, but may have an air outlet so that the air passing through the heat exchanger 40 is blown out in two directions or three directions.
while the present invention has been described with reference to the specific embodiments, the present invention is not limited to the first and second embodiments, and various modifications can be made within the scope of the present invention. For example, a configuration in which the contents described in the first and second embodiments are combined as appropriate may be adopted as one embodiment of the present invention.
