Usually, a horizontal louver is attached to the opening end side of the outlet, and left and right louvers are attached in the middle of the air passage on the back side, and each can be adjusted independently.
[0003]
[Problems to be solved by the invention]
By the way, when the cooling operation or the dehumidifying operation is performed, the dried heat exchange air is blown out from the outlet, and the heating operation is operated in winter when there are many dry weather conditions. In any case, the humidity around the outlet is reduced and static electricity is easily generated.
Therefore, over a long period of use, the wind direction guide device becomes dusty due to the influence of static electricity, becomes conspicuous, and becomes unsanitary. Therefore, it is desirable to adopt a configuration that allows the user to easily clean the wind direction guide device around the outlet.
[0004]

[0005]
Therefore, in an indoor unit provided with this type of wind direction guide device, even if the louver is conspicuous, it cannot be removed from the indoor unit main body, and there is no alternative but to insert a cleaning tool and clean it as it is. Naturally, it is difficult to clean and it is impossible to completely remove dust.
In particular, horizontal louvers are attached to the opening end of the air outlet so that they can be cleaned relatively easily, but left and right louvers are attached to the back side, so even if the horizontal louvers can be removed It is extremely difficult to completely clean the left and right louvers at that position.
[0006]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wind direction guide device of an automatic variable type so that the left and right louvers can be easily removed from the indoor unit main body so that work such as dust removal can be performed. It is another object of the present invention to provide an air conditioner indoor unit capable of improving workability by easily attaching left and right louvers to predetermined portions of the indoor unit main body again after the work is completed.
[0007]
[Means for Solving the Problems]
In order to satisfy the above object, the present invention provides a blower that houses a heat exchanger and an indoor blower in an indoor unit main body having a suction port at a front portion and a blowout port at a lower front portion, and communicates the indoor blower with the blowout port. A path is provided, comprising a wind direction guide device for setting a blowing direction of heat exchange air blown from a blowing port,
The wind direction guide device includes a drive source, a power transmission mechanism that extends in the longitudinal direction of the outlet and is reciprocally driven by the drive source, and is mechanically connected to the power transmission mechanism and is rotationally displaced to provide the outlet. And a plurality of left and right louvers that determine the direction of air blowing from the louver. The left and right louvers are detachably attached to the air passage and connected to the power transmission mechanism in a detachable manner.
[0008]
Further, the drive source and the power transmission mechanism of the wind direction guide device are disposed on the back side of the nose portion of the air passage in the indoor fan, and are hardly exposed in the air passage.
Further, the power transmission mechanism of the wind direction guide device includes a pair of left and right drive shafts that are arranged in a straight line with each other, and a clutch mechanism that is interposed between the drive shafts and that can adjust the distance between the drive shaft end portions. The left and right louvers are supported by a pair of louver bases for each of a plurality of louvers, and each louver base is detachably engaged with the air passage.
By adopting the means for solving the above problems, an automatic variable wind direction guide device is provided, and the left and right louvers can be easily removed from the indoor unit main body to perform work such as dust removal, and after the work is completed, The left and right louvers can be easily attached to predetermined portions of the indoor unit main body, thereby improving workability.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of the appearance of an indoor unit constituting an air conditioner, and FIG. 2 is a schematic longitudinal sectional view of the indoor unit.
[0010]
The indoor unit main body 1 includes a front panel 2 and a rear panel 3, and has a horizontally long shape whose width direction is extremely long in the vertical direction. The front panel 2 is curved and protrudes to the near side, and has side plates 1a on both left and right sides. The rear plate 3 has a horizontally long rectangular shape and is attached to a wall surface of the room to be air-conditioned.
A front suction port 4 is opened in a part of the front side of the front panel 2, and a movable panel 2a supported by an opening / closing drive mechanism 5 is fitted therein. When the operation is stopped, the movable panel 2a is flush with the front panel 2 and closes the front suction port 4. However, during operation, the movable panel 2a is controlled so as to protrude toward the front side and open the front suction port.
[0011]
An upper suction port 6 is provided over the front panel 2 and the rear plate 3. A frame-shaped bar 7 is fitted into the upper suction port 6, and is partitioned into a plurality of spaces by the bar.
Below the movable panel 2a, a decorative plate 2b made of a translucent material constituting a part of the front panel 2 is provided across the width of the indoor unit main body 1. Below the decorative plate 2b, two horizontal louvers 8a and 8b are provided in parallel.
[0012]
Each of the horizontal louvers 8a and 8b opens and closes an air outlet 9 provided along a lower portion of the front surface of the indoor unit main body 1, and changes a horizontal attitude angle in accordance with an operation condition to set a heat exchange air blowing direction. .
The horizontal louvers 8a and 8b constitute a wind direction guide device S together with left and right louvers 22 described later. The left and right louvers 22 and the horizontal louvers 8a, 8b are both detachably attached to the indoor unit main body 1.
[0013]
In the indoor unit main body 1, a heat exchanger 10 formed in a substantially inverted V-shape by a front heat exchanger section 10A and a rear heat exchanger section 10B is arranged. The front heat exchanger section 10A is formed in a curved shape that is substantially parallel to the front panel 2 with a gap therebetween, and the rear heat exchanger section 10B is formed in a straight shape and is obliquely inclined with the upper suction port 6. And face each other.
On the other hand, an air filter 11 is mounted in the indoor unit main body 1 facing the front suction port 4 and the upper suction port 6. The air filter 11 is interposed between each of the suction ports 4 and 6, the front heat exchanger section 10A and the upper heat exchanger section 10B, and is detachably provided between the open upper end of the outlet 9 and the lower end of the front panel 2. It is inserted.
[0014]
An electric precipitator 12 is mounted on the front side of the front heat exchanger section 10A of the heat exchanger 10 and at a position shifted to the right end side when viewed from the front with respect to the indoor unit main body 1. The electrostatic precipitator 12 includes a charging-side electrode that applies electric charges to dust in the flowing air, and a dust-collecting electrode that attracts and captures the charged dust.
The electric dust collector 12 generates a small amount of ozone when a high voltage is applied to the charging-side electrode in the same manner as in normal dust collection, but at this time, the blower 13 is stopped or stopped in order to restrict the flow of surrounding air. When the low-speed operation is performed, the indoor air hardly circulates through the electrostatic precipitator 12, so that the generated ozone does not disappear and acts to gradually fill the indoor unit main body, and sterilizes the indoor unit main body. Function as
[0015]
An indoor blower 13 is arranged between the front and rear heat exchanger portions 10A and 10B of the heat exchanger 10 and between the heat exchanger 10 and the outlet 9. That is, the indoor blower 13 is located inside the umbrella-shaped heat exchanger 10.
The lower end of the front heat exchanger section 10A rests on the front drain pan 16a, and the lower end of the rear heat exchanger section 10B rests on the rear drain pan 16b, and the drain drops from the heat exchanger sections 10A, 10B. Water can be received and drained to the outside via a drain hose (not shown).
[0016]
Partial side wall outer surfaces of the front and rear drain pans 16a and 16b are provided at positions close to the indoor blower 13. In particular, a nose 20 for the cross flow fan of the indoor blower 13 is integrally assembled with the front drain pan 16a.
The nose 20 and the side wall portions of the front and rear drain pans 16a and 16b and both side portions of the outlet 9 are connected by a partition wall member 17. The space surrounded by the partition member 17 is an air passage 18 that communicates the nose 20 with the outlet 9.
[0017]
FIG. 3 is an enlarged sectional view showing the outlet 9 and the air passage 18.
As described above, the outlet 9 is provided with the horizontal louvers 8a and 8b for guiding the horizontal wind direction, and the left and right louvers 22 for guiding the horizontal wind direction are provided in the air passage 18 at the back of these horizontal louvers. Are provided, and these constitute the wind direction guide device S.
[0018]
The horizontal louvers 8a and 8b are provided in parallel in two front and rear rows, and are connected to a driving source (not shown) and are driven to rotate. Triangular ribs a are provided on both left and right ends of each of the horizontal louvers 8a, 8b.
The locking pin b is connected to the driving source, and can change the posture angle of the horizontal louvers 8a and 8b, and the horizontal louver itself is detachable from the outlet 9.
[0019]
The left and right louvers 22 have a detailed configuration shown in FIG. 4 and subsequent figures, and will be described in detail later. Here, the left and right louvers 22 rotate through a power transmission mechanism 25 supported by the nose 20 so as to be movable. It is only described that it is driven.
The nose 20 is formed in a substantially L-shaped cross section, and the front side faces the air passage 18. The power transmission mechanism 25 is disposed on the back side of the nose 20, and the power transmission mechanism 25 is hardly exposed in the air passage 18.
[0020]
When the operation switch of the remote controller is turned on in the indoor unit of the air conditioner configured as described above, the movable panel 2 a forming a part of the front panel 2 opens the front suction port 4.
Further, the horizontal louvers 8a and 8b provided in the outlet 9 are rotated according to the designation of the cooling operation and the heating operation, and their postures are set. The left and right louvers 22 perform a so-called swing motion so that the heat exchange air is blown out over a wide range without being concentrated on a part.
[0021]
While the indoor blower 13 performs a blowing action, the compressor of the outdoor unit is driven to start the refrigeration cycle operation. The indoor air is guided into the indoor unit main body 1 from the upper suction port 6 and the front suction port 4, and passes through the air filter 11.
Most of the dust contained in the indoor air is captured by the air filter 11 and passes through the heat exchanger 10 in a state where the dust has been removed to perform a heat exchange action. This heat exchange air is guided to the air passage 18, and the blowing direction is set in a wide range in the left-right direction by the swinging motion of the left and right louvers 22 constituting the wind direction guide device S.
[0022]
The power transmission mechanism 25 that drives the left and right louvers 22 is disposed on the back side of the air passage 18, and most of the power transmission mechanism 25 is not exposed in the air passage. You do not have to be a resistance to ventilation.
When the heat exchange air reaches and passes through the outlet 9, the blowing direction is set according to the horizontal posture of the horizontal louvers 8a and 8b, and the air is blown into the room to continue the efficient air conditioning operation.
[0023]
In addition, by causing the electric dust collector 12 to function, fine dust that has passed through the air filter 11 is completely captured, and purified air is blown into the room from the blowout port 9 via the heat exchanger 10.
Next, the wind direction guide device S related to the left and right louvers 22 will be described.
FIG. 4 is an enlarged perspective view of a part of the wind direction guide device S, and FIG. 5A is a perspective view of the wind direction guide device S attached to the nose 20 of the indoor unit main body 1 taken out and viewed from above. (B) is a perspective view of a part of the wind direction guide device S removed and viewed from below, and FIG. 6 is a perspective view of the wind direction guide device S with the nose 20 removed.
[0024]
The wind direction guide device S includes a swing motor 40 as a drive source having a swing axis d that is swingably driven, the power transmission mechanism 25 mechanically connected to the swing axis of the swing motor, And the left and right louvers 22 for determining the wind guiding direction in accordance with the reciprocating motion of the power transmission mechanism.
To be more specific, the oscillating motor 40 is mounted and fixed to the part of the indoor unit main body 1 at a position slightly separated from the left end of the nose 20 by appropriate means. The rotating shaft d of the swing motor 40 extends downward, and a drive cam 26 constituting the power transmission mechanism 25 is attached to the lower end of the rotating shaft.
[0025]
The drive cam 26 is engaged with one end of a drive arm 27 extending near the end of the nose in parallel with the longitudinal direction of the nose 20. The other end of the drive arm 27 is rotatably connected via a pin to an end of an intermediate arm 28 extending in a direction substantially perpendicular to the arm.
The intermediate arm 28 is slidably attached to the lower surface of the nose 20, and a part of the power transmission mechanism 25 is actually exposed to the surface of the air passage 18. Is one end of the nose, and the length is so small that there is almost no draft resistance.
[0026]
The other end of the intermediate arm 28 is rotatably connected to a first drive shaft 29 movably supported along the upper surface of the nose 20 via appropriate means. The first drive shaft body 29 is connected to a second drive shaft body 31 via a clutch mechanism 30 described later.
Therefore, the first drive shaft body 29, the clutch mechanism 30 and the second drive shaft body 31 are linearly arranged on the upper surface along the longitudinal direction of the nose 20, and they are not exposed in the air passage 18 at all. .
[0027]
Actuation projections 32 projecting rearward are integrally provided on the left end in the drawing of the first drive shaft 29 and on the left end in the drawing of the second drive shaft 31, respectively. These actuating projections 32 engage with receiving cams 34 provided on a pair of left and right louver bases 33.
To be more specific, the nose 20 is provided with a pair of left and right long holes 35 for detachably supporting the pair of left and right louver bases 33. The louver base 33 is provided with a plurality of bushings 36 at predetermined intervals, and the support shaft portions e of the left and right louvers 22 are rotatably fitted to the respective bushings 36.
[0028]
At each of the left and right ends of each louver base 33, an elastically deformable hook portion f formed in an inverted U-shape is integrally provided, and is hooked to both side ends of the nose opening 35 so as to be freely detachable. It has become so. When the louver base 33 is attached to the nose 20, the louver base 33 forms the same plane as the nose 20.
The left and right louvers 22 are on the lower surface side of the louver base 33 and protrude into the air passage 18. A wind direction adjusting bar 37 is rotatably mounted on all the louvers 22 of each louver base 33 via a rotating mechanism G including a pin and a long hole.
[0029]
A knob j is integrally provided at the center of the wind direction adjusting bar 37. When the horizontal louvers 8a and 8b are opened with respect to the outlet 9, a finger can be inserted into the outlet. The knob j can be operated.
That is, when the wind direction adjusting bar 37 is moved leftward or rightward with the knob j, the directions of all the left and right louvers 22 connected to the bar via the rotating mechanism G are changed simultaneously.
[0030]
Further, when one left and right louver 22 is rotated, the other left and right louvers 22 are simultaneously directed in the direction via the rotation mechanism G of the wind direction adjusting bar 37, so that a so-called parallel link mechanism is formed.
In the wind direction guide device S related to the left and right louvers 22 configured as described above, the rotation shaft d is rotated and driven within a predetermined angle range by driving the swing motor 40.
[0031]
Accordingly, the drive cam 26 rotates to drive the drive bar 27, and the first drive shaft body 29 and the second drive shaft body 31 are reciprocated by a predetermined amount together with the clutch mechanism 30 via the intermediate bar 28.
The reciprocating motion of the first and second drive shafts 29, 31 and the like is caused by the engagement of the operating projection 32 of the first and second drive shafts with the receiving cam 34 of the left and right louver 22 located at the left end. Thus, the rotational displacement of the left and right louvers 22 is changed.
[0032]
The rotation of the left and right louvers 22 is converted into a reciprocating motion of the wind direction adjusting bar 37 via the rotation mechanism G, and the other left and right louvers 22 connected to this bar are simultaneously rotated and displaced. Eventually, the action of the swing motor 40 is transmitted to all the left and right louvers 22 via the power transmission mechanism 25, and the left and right louvers make a so-called swinging motion.
In this way, the air blowing direction of the heat exchange air is automatically changed by the left and right louvers 22 continuously during the air conditioning operation. The heat exchange air is blown over a wide range, and an efficient heat exchange action is performed.
[0033]
Since dust adheres to each of the left and right louvers 22 over a long period of use, the dust must be removed. In this case, it is safer and more reliable to first remove the horizontal louvers 8a and 8b, and then remove the left and right louvers 22 and place them at hand for cleaning.
Therefore, the left and right ends of the louver base 33 are gripped and pulled downward. The hook portion f of the louver base 33 comes off from both side ends of the nose opening 35 and separates from the nose 20. At the same time, the receiving cam 34 of the louver base 33 is separated from the operating projection 32 of each drive shaft 29, 31.
[0034]
That is, the nose 20 can be detached from the nose 20 like the left louver base 33 shown in FIG. 5B. Then, like the left louver base 33 shown in FIG. 6, the receiving cam 34 is separated from the operating projection 32 of the first drive rod 29, and the left and right louvers 22 can be removed from the power transmission mechanism 25.
With the removed louver base 33 at hand, dust attached to each of the left and right louvers 22 is removed, and after complete cleaning is completed, the louver base 33 is attached to the indoor unit body 1 again. That is, the louver base 33 is lifted up to the indoor unit main body 1 by holding both ends thereof, and further inserted into the air passage 18 through the outlet 9.
[0035]
The louver base 33 may be opposed to the nose opening 35, and the louver base may be pushed up without changing its position to hook the hook f to the end of the opening. At the same time, the receiving cam 34 engages with the operating projection 32 of each drive rod 29,31.
Therefore, the left and right louvers 22 are assembled again at the predetermined positions, and are mechanically connected to the power transmission mechanism 25 again. When the air conditioning operation is performed again, the left and right louvers 22 rotate integrally.
[0036]
In this manner, the left and right louvers 22 can be extremely easily detachably attached to the nose 20, and the left and right louvers 22 can be extremely easily detachably connected to the power transmission mechanism 25. Can be improved.
Next, the clutch mechanism 30 will be described in detail.
[0037]
FIG. 7 is an enlarged perspective view of the clutch mechanism 30, and FIGS. 8A, 8B, and 8C show different states of the clutch mechanism 30 and the states of the right and left louvers 22 corresponding to the different states.
The clutch mechanism 30 includes a receiving portion 42 provided integrally with the right end of the first drive shaft 29 and an insertion portion 43 provided integrally with the left end of the second drive shaft 31. ing.
[0038]
The receiving portion 42 has an open end surface, a wall portion n at a predetermined length along the longitudinal direction, and is formed in a concave groove shape with an open upper surface. Further, a claw lid 44 having a claw protruding in the groove bottom direction is provided integrally so as to cover a part of the upper surface of the receiving portion 42.
The cross-sectional area of the insertion portion 43 is formed small with respect to the opening area of the reception portion so that the insertion portion 43 is inserted into the inside from the opening end of the receiving portion 42 and is movable. On the upper surface side of the insertion portion 43, a wavy hooking portion 45 composed of a triangular groove continuous in the longitudinal direction is provided.
[0039]
The claw portion of the above-mentioned claw cover 44 is engaged with the wavy engagement portion 45, and the mutual position of the receiving portion 42 and the insertion portion 43 is maintained. The position of the claw portion of the claw lid 44 with respect to the wavy hooking portion 45 can be freely selected, and the position can be freely changed.
The clutch mechanism 30 thus configured is supported in a holding state by a support piece 46 provided integrally with the nose 20, and the entire clutch mechanism 30 is movable and displaceable with respect to the support piece 46. It is.
[0040]
Accordingly, there is no problem in displacing the clutch mechanism 30 integrally with the first drive shaft body 29 and the second drive shaft body 31 which are reciprocally driven by the swing motor 40.
Further, by performing a simple operation on the clutch mechanism 30 by using the knobs j of the left and right wind direction adjusting bars 37, the directions of the left and right louvers 22 supported by the left and right louver bases 33 can be freely changed as appropriate.
[0041]
For example, as shown in FIG. 8A, the insertion portion 43 constituting the clutch mechanism 30 is inserted so that its end face is located at an intermediate portion between the wall portion n of the receiving portion 42 and the lowest position. . This is almost the same as the state shown in FIG.
At this time, the tips of the left and right louvers 22 supported by the left and right louver bases 33 rotate about the support shaft e, and are directed to almost the same angle. That is, the left and right louvers 22 are parallel to each other.
[0042]
On the other hand, as shown in FIG. 8B, a state in which the end face of the insertion portion 43 is farthest from the wall portion n of the reception portion 42 of the clutch mechanism 30, that is, the insertion portion 43 is received. It is inserted into the shallowest position with respect to the part 42.
At this time, the left and right louvers 22 supported by the left and right louver bases 33 rotate so that the distal ends are separated from each other with the support shaft e as a fulcrum. There is).
[0043]
Further, as shown in FIG. 8C, a state in which the end face of the insertion portion 43 contacts the wall surface n of the reception portion 42 of the clutch mechanism 30, that is, the insertion portion 43 reaches the deepest position with respect to the reception portion 42. Insert.
At this time, the left and right louvers 22 supported by the left and right louver bases 33 rotate so that their tip sides approach each other with the support shaft e as a fulcrum. There is).
[0044]
If the air-conditioning operation is started after setting to any of FIGS. 8A, 8B, and 8C, or if the above-described operation is performed during the air-conditioning operation, the left and right louvers 22 will be based on the posture in each drawing. Perform a swing motion.
In other words, the direction of the left and right louvers 22 in the left and right louver bases 33 can be arbitrarily set by providing the clutch mechanism 30 having a simple configuration and interposing between the first drive shaft body 29 and the second drive shaft body 31. Can be set to improve comfort.
