Problems to be solved by the invention
The above-described conventional indoor unit of an air conditioner has the following problems: since the driving portions are located on both sides of the rotational axis direction of the shutter, the length of the housing in the rotational axis direction of the shutter becomes long.
Further, when the length of the casing is simply shortened, the length of the air outlet in the direction of the rotation axis of the flap is also shortened, which causes deterioration in performance such as a reduction in the air volume of the air outlet.
Therefore, an object of the present invention is to provide an indoor unit of an air conditioner that can be reduced in size and improved in performance.
Means for solving the problems
An indoor unit of an air conditioner according to an aspect of the present invention includes:
a casing provided with a blow-out port and having a casing main body;
a centrifugal fan disposed within the housing;
a heat exchanger disposed between the casing and the centrifugal fan;
a rotatable flap that controls the wind direction of the blown air from the air outlet; and
a driving portion that is disposed within the housing and generates a driving force for rotating the shutter,
the driving portion is adjacent to the flapper in a direction orthogonal to a rotational axis direction of the flapper.
According to the above configuration, the driving portion is disposed in the casing so as to be adjacent to the flap in the direction orthogonal to the rotational axis direction of the flap, whereby the driving portion can be prevented from being adjacent to the outlet in the rotational axis direction of the flap. As a result, even if the length of the casing is shortened in the direction of the rotation axis of the flap, the length of the air outlet can be increased, and the air volume of the air outlet can be increased. Therefore, the indoor unit of the air conditioner can be miniaturized and can improve the performance.
In the indoor unit of an air conditioner according to one embodiment,
the length of the baffle in the direction of the rotation axis is 85% or more of the length of the housing main body in the direction of the rotation axis of the baffle.
According to the above embodiment, the length of the flap in the rotational axis direction is set to 85% or more of the length of the housing main body in the rotational axis direction of the flap, so that the control of the wind direction is facilitated and the air blowing performance can be improved.
In the indoor unit of an air conditioner according to one embodiment,
the length of the outlet in the rotational axis direction of the flap 20 is 85% or more of the length of the casing main body in the rotational axis direction of the flap 20.
According to the above-described embodiment, the length of the air outlet in the rotational axis direction of the flap is set to 85% or more of the length of the casing main body in the rotational axis direction of the flap, whereby the air volume of the air outlet can be reliably increased.
In the indoor unit of an air conditioner according to one embodiment,
the baffle has:
a shutter main body extending in the rotational axis direction;
a first auxiliary baffle extending from one end portion of the baffle main body toward a side of the casing opposite to the blow-out side; and
a second auxiliary baffle extending from the other end portion of the baffle main body toward a side of the casing opposite to the blow-out side,
the center of gravity of the baffle is located on the blower outlet side of the casing with respect to the rotational axis within the rotational range of the baffle.
According to the above embodiment, since the center of gravity of the flap is located on the blow-outlet side of the housing with respect to the rotational axis within the rotational range of the flap, the flap can be smoothly rotated.
In the indoor unit of an air conditioner according to one embodiment,
the indoor unit of the air conditioner includes a link mechanism that transmits a driving force of the driving unit to the flap to rotate the flap.
According to the above embodiment, since the driving force of the driving portion is transmitted to the flapper via the link mechanism, the degree of freedom of the installation place of the driving portion can be improved.
Effects of the invention
As apparent from the above, the present invention can provide an indoor unit of an air conditioner that can be reduced in size and improved in performance.

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.
Fig. 1 is a perspective view of an indoor unit of an air conditioner according to an 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. 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 of the present 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 baffle 20 has an コ -shaped shape when viewed in plan, and controls the direction of the air blown out from the air outlet 10.
More specifically, the baffle 20 has: a shutter main body 20a extending along the rotation shaft 21; a first auxiliary barrier 20b connected to one end of the barrier main body 20 a; and a second subsidiary barrier 20c connected to the other end portion of the barrier main body 20 a.
The first auxiliary baffle 20b extends from one end of the baffle main body 20a toward the opposite side of the panel 2 from the outlet 10 side. The first auxiliary damper 20b is connected to the stepping motor 80 via a link mechanism 90. The stepping motor 80 is an example of a driving unit.
The second auxiliary baffle 20c extends from the other end portion of the baffle main body 20a toward the opposite side to the blow-out opening 10 side of the panel 2. That is, the extending direction of the second auxiliary barrier 20c is parallel to the extending direction of the first auxiliary barrier 20 b.
The length L1 of the flap 20 is set to be 85% or more of the length L2 (shown in fig. 5) of the housing main body 1 in a direction parallel to the rotational axis 21 of the flap 20 (hereinafter, referred to as "rotational axis direction of the flap 20"). For example, if the length L2 of the casing main body 1 is 315mm, the length L1 of the baffle 20 is set to 280 mm.
The center of gravity 22 of the baffle 20 is set in the baffle body 20a with a gap from the pivot shaft 21. In other words, the baffle 20 is formed such that the center of gravity 22 of the baffle 20 is located closer to the outlet 10 side of the casing main body 1 than the rotation axis 21.
The stepping motor 80 is disposed in a space formed by the housing main body 1, the panel 2, and the grill 3, and is adjacent to the baffle 20 in a direction orthogonal to the rotational axis direction of the baffle 20. The stepping motor 80 is located on the opposite side of the rotation shaft 21 from the outlet 10 side of the casing main body 1. Further, the stepping motor 80 generates a driving force for rotating the shutter 20. At this time, the flap 20 receives the driving force of the stepping motor 80 via the link mechanism 90 and rotates about the rotation shaft 21. That is, the driving force of the stepping motor 80 is transmitted to the barrier 20 via the link mechanism 90, and the barrier 20 rotates. Further, the stepping motor 80 may be positioned on the outlet 10 side of the casing main body 1 with respect to the rotation shaft 21.
Further, as shown in fig. 3, a suction port 1a is provided in the center 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.
The outlet 10 side of the casing main body 1 is the first wall 11 (shown in fig. 5) side of the casing main body 1.
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 baffle plate 20 is formed near the first wall portion 11 of the casing main body 1. The baffle 20 is disposed below the space on the first wall portion 11 side in the housing main body 1.
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, for example, when viewed in plan.
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.
Fig. 6 shows a state in which the indoor unit shown in fig. 5 has the shutter 20 attached thereto (as indicated by diagonal lines), and fig. 7 shows a state in which the shutter 20 of the indoor unit is removed. In fig. 6 and 7, the same components as those in fig. 1 to 5 are denoted by the same reference numerals as those in fig. 1 to 5.
As seen in a plan view, as shown in fig. 6, the baffle main body 20a and the first and second auxiliary baffles 20b and 20c are arranged so as not to overlap the heat exchanger 40. Further, the baffle main body 20a and the first and second auxiliary baffles 20b and 20c are located between the first wall portion 11 of the casing main body 1 and the second wall portion 12 of the casing main body 1 as viewed in plan. The shutter main body 20a is provided along the first wall portion 11 of the housing main body 1. Further, the first auxiliary baffle 20b extends along the third wall portion 13 of the housing main body 1. On the other hand, the second auxiliary barrier 20c extends along the fourth wall portion 14 of the casing main body 1. Further, the distal end portions of the first and second auxiliary flappers 20b and 20c are located on the second wall portion 12 side of the housing main body 1 with respect to the flapper main body 20a in plan view.
As shown in fig. 6 and 7, the outlet 10 is composed of a rectangular first outlet 10a and second and third outlets 10b and 10c provided along the first wall 11 of the casing main body 1. The second outlet 10b extends from one end of the first outlet 10a toward the third wall 13 of the casing main body 1, is bent, and extends toward the second wall 12 of the casing main body 1. On the other hand, the third blowout part 10c extends from the other end part of the first blowout part 10a toward the fourth wall part 14 side of the casing main body 1, then bends and extends toward the second wall part 12 of the casing main body 1.
Further, the length L3 of the outlet 10 in the rotational axis direction of the flap 20 is set to be 85% or more of the length L2 of the casing main body 1. For example, if the length L2 of the casing main body 1 is 315mm, the length L3 of the air outlet 10 is 283 mm.
Fig. 8 is a side view of the baffle 20, the stepping motor 80, and the link mechanism 90.
The link mechanism 90 includes: a first link 90 a; a second link 90b having one end connected to one end of the first link 90 a; and a third link 90c having one end coupled to the other end of the first link 90 a. The other end of the second link 90b is coupled to the rotation shaft of the stepping motor 80. The other end of the third link 90c is connected to the first auxiliary flap 20 b.
The flapper 20 is rotated in the directions of arrows R1, R2 by the driving force of the stepping motor 80 via the link mechanism 90.
Fig. 9 is a top view of a portion of the baffle 20. Fig. 10 is a side view of the baffle plate 20.
As shown in fig. 9 and 10, when the baffle 20 closes the outlet 10, the first and second auxiliary baffles 20b and 20c are each inclined such that the end on the opposite side of the baffle main body 20a is lower than the end on the baffle main body 20a side.
When the swirl fan 30 is driven to blow out the blown air from the outlet 10, the flap 20 rotates between the upper limit position 23 indicated by the two-dot chain line and the lower limit position 24 indicated by the two-dot chain line. At this time, the center of gravity of the flap 20 moves so as to draw an arc about the pivot shaft 21, and is located on the right side in fig. 10 with respect to a vertical plane including the pivot shaft 21. That is, the center of gravity 22 of the flap 20 is positioned on the blow-out port 10 side of the panel 2 with respect to the rotation axis 21 in the rotation range of the flap 20. When the blown air from the blowout port 10 is to be sent to a remote place, the position of the damper 20 is at the upper limit position 23. On the other hand, when the blown air from the blowout port 10 is to be sent to the near place, the position of the flap 20 is at the lower limit position 24.
When the flap 20 is rotated between the upper limit position 23 and the lower limit position 24, the first and second auxiliary flaps 20b enter the inside of the outlet 10.
According to the indoor unit configured as described above, since the stepping motor 80 is adjacent to the baffle 20 in the direction orthogonal to the rotational axis direction of the baffle 20, the stepping motor 80 can be prevented from being adjacent to the outlet 10 in the rotational axis direction of the baffle 20. As a result, even if the length L2 of the casing main body 1 is shortened, the length L3 of the air outlet 10 can be increased, and the air volume of the air outlet 10 can be increased. Therefore, the indoor unit can be downsized and can improve performance.
Further, since the length L1 of the flap 20 is set to 85% or more of the length L2 of the casing main body 1, the control of the wind direction is facilitated, and the air blowing performance can be improved.
Further, since the length L3 of the air outlet 10 is set to 85% or more of the length L2 of the casing main body 1, the air volume of the air outlet 10 can be reliably increased.
Further, in the range of rotation of the flap 20, the center of gravity 22 of the flap 20 is positioned on the side of the outlet 10 of the panel 2 with respect to the rotation shaft 21, and therefore the flap 20 can be smoothly rotated.
In contrast, if the center of gravity 22 of the flap 20 is located on the side of the outlet 10 of the panel 2 with respect to the rotation axis 21 in a part of the rotation range of the flap 20 and the center of gravity 22 of the flap 20 is located on the opposite side of the outlet 10 of the panel 2 with respect to the rotation axis 21 in another part of the rotation range of the flap 20, the rotation of the flap 20 will not be smooth.
Further, when the flap 20 is rotated between the upper limit position 23 and the lower limit position 24, the first and second auxiliary flaps 20b enter the inside of the outlet 10, and therefore the outlet 10 can blow air from the air passage P with good controllability.
Further, since the driving force of the stepping motor 80 is transmitted to the baffle 20 via the link mechanism 90, the degree of freedom of the installation place of the stepping motor 80 can be improved.
In the above-described embodiment, the indoor unit including the casing having the rectangular parallelepiped shape formed by the casing main body 1, the panel 2, and the grill 3 has been described, but the shape of the casing is not limited to this.
In the above-described embodiment, 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 above-described embodiment, 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.
In the above-described embodiment, the link mechanism is used as an example of the transmission mechanism for transmitting the driving force of the driving portion to the flapper, but a mechanism including a rack-and-pinion gear, a mechanism including a belt and a pulley, a mechanism including a gear train, or the like may be used.
While the present invention has been described with reference to specific embodiments, the present invention is not limited to the above 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 above embodiments are combined as appropriate may be one embodiment of the present invention.
