By the way, in an air conditioner, there is a demand for air to be widely expanded in the left-right direction when air is desired to be air-conditioned more uniformly. However, in the conventional configuration, the flat vertical flap is tilted in the left-right direction to change the direction of the wind, so that airflow resistance occurs when air passes in the vicinity of the vertical flap. The ventilation resistance is particularly increased as the vertical flap is largely inclined, so that it is difficult to blow air in a wider range in the left-right direction and far away.
The present invention has been made in view of the above-described circumstances, and an object thereof is to allow air to be blown to a wider range in the left-right direction and far away in an air conditioner including a vertical flap.

It is good also as composition to do.

The vertical flap has the pivot shaft at one end and is pivoted to the left and right via a connecting portion provided at the other end, and the flexible portion is connected to the pivot shaft and the connecting portion. You may be provided in the substantially whole area between.
Further, the connecting portion may be constituted by a connecting shaft extending substantially parallel to the rotating shaft, and the flexible portion may be stretched between the connecting shaft and the rotating shaft.

In addition, a plurality of the vertical flaps may be connected to a slide member that slides to the left and right, and may be configured to rotate in conjunction with the slide of the slide member.
In addition, when receiving an instruction to blow air widely in the width direction, a control unit may be provided that inclines the vertical flap outward in the width direction and increases the air volume of the blower fan of the indoor unit.

  According to the present invention, in an air conditioner provided with a vertical flap, air can be blown in a wider range in the left-right direction and can be blown far away.

It is fixed to the blower fan 31 by a set screw 42 that is screwed from below. In addition, an electrical box 55 that houses the control unit 58 and the like is disposed on the side of the fan motor 46.
In the lower part of the back side of the frame 3, a pipe housing part 33, which is a longitudinal space for housing refrigerant pipes and drain pipes, is formed, and pipe retainers 52 and 53 that hold down the pipe in the pipe housing part 33. It is attached.

A front panel 16 is attached to the grill 10 so that an upper surface inlet port 11A and a front surface inlet port 11B extend in the width direction of the indoor unit 12 and open, and the front surface inlet port 11B is covered.
As shown in FIGS. 1 and 3, on the lower surface of the indoor unit 12, a blowing surface 35 that is continuous with the lower edge of the front panel 16 and is inclined downward toward the wall W side, and from the blowing surface 35 to the wall W side. A lower end surface 37 extending substantially horizontally is formed. The blowout surface 35 is provided with an air outlet 13 that blows out air from the blower fan 31, and the air outlet 13 is closed by plate-shaped flaps 60 and 60 so as to be freely opened and closed. In FIG. 3, the flap 60 is not shown for convenience of understanding.

The blower fan 31 sucks room air from the upper surface suction port 11A and the front surface suction port 11B through the indoor heat exchanger 29, and blows out the air heat-exchanged in the indoor heat exchanger 29 from the air outlet 13 into the conditioned room. . Between the blower fan 31 and the blower outlet 13, a guide chamber 36 that guides the blown air from the blower fan 31 to the blower outlet 13 is provided. The upper surface of the guide chamber 36 is formed by a lower portion of a drain pan 34 that is inclined downward on the front side of the indoor unit 12, and the lower portion of the guide chamber 36 is a scroll portion that is inclined downward on the front side of the indoor unit 12. 32 is formed by a lower portion.

Further, the blower fan 31 is configured to be able to switch the number of rotations between three levels of high, medium, and low, and the amount of air discharged from the blower fan 31 increases as the number of rotations increases. That is, according to the rotation speed of the blower fan 31, the setting of the air volume is changed to strong, medium, and weak.

  The flaps 60, 60 are two horizontal blades that change the direction of the air blown from the air outlet 13 up and down. Each flap 60 is formed in a plate shape extending in the width direction of the indoor unit 12 and has a flap shaft 61 extending in the longitudinal direction of the flap 60. Each flap 60 rotates up and down around the flap shaft 61. The two flaps 60, 60 are driven in conjunction with the flap drive motor 63 of the indoor unit 12, open and close the air outlet 13 so as to maintain a substantially parallel positional relationship, and are blown out from the air outlet 13. Change the wind direction in the vertical direction.

A plurality of vertical flaps 85 as vertical blades that change the wind direction to the left and right are arranged side by side on the exit side of the scroll portion 32. The vertical flap 85 includes a plurality of pieces (eight in the present embodiment) divided into left and right as a set, a left flap 71 provided on the left side of the center in the width direction of the air outlet 13, and a center of the vertical flap 85. Also has a right side flap 72 provided on the right side. Each of the left flap 71 and the right flap 72 is connected to one set by slide plates 73A and 73B (slide members) provided at the top and bottom, and is disposed on the upstream side of the flaps 60 and 60. The vertical flap 85 is connected to a vertical flap drive motor (not shown) via slide plates 73A and 73B, and is moved to the left and right according to the operation of the vertical flap drive motor or the operation of the slide plates 73A and 73B by the user's hand. The direction is changed.
Specifically, the indoor unit 12 is provided with a remote controller (not shown), and the user can adjust the direction of the vertical flap 85 to a desired direction by operating the remote controller.

FIG. 4 is a perspective view showing a configuration in the vicinity of one piece of the vertical flap 85. Here, in FIG. 4, the right flap 72 is illustrated, but since the right flap 72 and the left flap 71 are formed symmetrically, detailed description of the left flap 71 is omitted.
As shown in FIGS. 1 and 4, one vertical flap body 85 </ b> A includes a flap plate 75 made of a flexible elastomer, a rotating shaft 76 provided at one end 75 </ b> A of the flap plate 75, and a flap. A connecting shaft 77 (connecting portion) provided at the other end 75B of the plate 75 is provided. The right flap 72 and the left flap 71 are configured by connecting eight vertical flap bodies 85A via slide plates 73A and 73B, respectively. Here, the elastomer may be either resin or rubber.

The rotating shaft 76 extends vertically on the upstream side close to the blower fan 31 in the air outlet 13, the upper end is connected to the tongue portion 48 of the frame 3, the lower end is connected to the scroll portion 32, and the flap plate 75 is connected. The rotation shaft 76 is supported so as to be rotatable.
The connection shaft 77 extends substantially parallel to the rotation shaft 76 on the downstream side of the rotation shaft 76, and slide plates 73 </ b> A and 73 </ b> B are rotatable about the connection shaft 77 at the upper end portion and the lower end portion. It is connected. At the upper end and the lower end of the connecting shaft 77, flange portions 77A that abut the lower surface of the slide plate 73A and the upper surface of the slide plate 73B and position the connecting shaft 77 between the slide plates 73A and 73B are provided.

The flap plate 75 is formed in a rectangular plate shape and is spanned between the rotation shaft 76 and the connection shaft 77, and a portion other than the rotation shaft 76 and the connection shaft 77 in the vertical flap body 85A, that is, the vertical plate. A substantially entire area of the plate surface 78 of the flap body 85A is constituted by a flap plate 75 as a flexible portion.
Since the flap plate 75 is made of a flexible elastomer and can be expanded and contracted, the distance between the rotation shaft 76 and the connecting shaft 77 is variable as the flap plate 75 extends, and the flap plate 75 When an external force such as wind pressure having a component that pushes the plate surface 78 is applied, the flap plate 75 is deformed by the external force. In addition, as the elastomer of the flap plate 75, an elastomer having a characteristic that the flexibility is maintained in the temperature range of the blown air in the cooling operation and the heating operation of the indoor unit 12 is used.

As shown in FIGS. 2 and 4, the slide plates 73A and 73B are plates that are provided in parallel to each other and extend in the width direction (left-right direction) of the air outlet 13 along the vertical flap body 85A. Each flap plate 75 is provided between the plates 73 </ b> A and 73 </ b> B via a connecting shaft 77.
The slide plates 73A and 73B are driven in the left-right direction substantially orthogonal to the axial direction of the rotation shaft 76 as shown by an arrow M in FIG. 4 by driving a vertical flap drive motor (not shown) controlled by the control unit 58. As the slide operation is performed, the connecting shafts 77 move left and right, and the vertical flap body 85A rotates left and right around the rotation shaft 76 as a rotation center. The slide plates 73A and 73B are positioned so as not to move in the front-rear direction of the indoor unit 12, and move only in the left-right direction.

FIG. 5 is a schematic plan view showing a state in which the vertical flap 85 blows air in front of the indoor unit 12. Here, in FIG. 5, the direction of the airflow X1 flowing through the guide chamber 36 and flowing into the vertical flap 85 and the direction of the airflow Y1 blown out through the vertical flap 85 are indicated by arrows. Further, in FIG. 5, the slide plate 73A is not shown.
As shown in FIG. 5, the vertical flap bodies 85A are arranged in parallel with each other at substantially equal intervals in the width direction of the air outlet 13 (see FIG. 3), and each connecting shaft 77 is connected to the slide plate 73A. , 73B. The eight vertical flap bodies 85A of each of the right flap 72 and the left flap 71 are changed in angle at a time by sliding the slide plates 73A and 73B to the left and right, and are also changed to substantially the same angle.

When air flows straight from the outlet 13 to the front of the indoor unit 12 without changing the wind direction of the airflow X1 to the left and right, each vertical flap body 85A has an angle substantially parallel to the direction in which the airflow X1 flows, that is, the width of the outlet 13 Oriented at an angle substantially perpendicular to the direction.
In the state shown in FIG. 5, the airflow X1 blown from the blower fan 31 passes through the vertical flap 85 along the plate surface 78 of the flap plate 75 substantially parallel to the airflow X1 and becomes the airflow Y1 flowing forward, and then Blows through the flaps 60,60. At this time, the airflow X1 only flows substantially parallel to the flap plate 75, and the plate surface 78 of the flap plate 75 is hardly deformed by the wind pressure of the airflow X1 regardless of the air volume of the blower fan 31.

FIG. 6 is a schematic plan view showing a state in which the vertical flap 85 blows left and right. Here, FIG. 6A shows a state where the air volume of the blower fan 31 is low, and FIG. 6B shows a state where the air volume is strong.
6A and 6B, the directions of the airflows X2 and X3 flowing through the guide chamber 36 and flowing into the vertical flap 85 and the airflows Y2 and Y3 blown out through the vertical flap 85 are shown. Directions are indicated by arrows, and the lengths of these arrows correspond to the amount of air flow.

As shown in FIG. 6A, the slide plates 73A and 73B are slid outward in the width direction of the air outlet 13 so that each vertical flap body 85A is rotated and tilted about each rotation shaft 76. Directed to the outside in the width direction of the air outlet 13. That is, in the right flap 72, each vertical flap body 85A is directed forward in the right direction, and in the left flap 71, each vertical flap body 85A is directed forward in the left direction.
Further, in the state where each vertical flap body 85A is inclined, the distance between the rotating shaft 76 and the connecting shaft 77 is increased, so that the flap plate 75 is in an extended state.

  When the air flow of the blower fan 31 is weak in a state where the vertical flap 85 is inclined to the left and right, the airflow X2 flowing into the vertical flap 85 hits the plate surface 78 of the flap plate 75 as shown in FIG. By flowing along the inclined plate surface 78, the blowing direction is changed from the forward direction to the angle A, and blown out in the left and right outer directions. In this case, the air volume of the blower fan 31 is weak, and the plate surface 78 is hardly deformed by the wind pressure and maintains a flat plate shape. For this reason, when the airflow X2 hits the plate surface 78, the direction is changed relatively abruptly, and the ventilation resistance is increased.

  When the air volume of the blower fan 31 is strong in a state where the vertical flap 85 is inclined to the left and right outsides, the airflow X3 flowing into the vertical flap 85 is an inclined plate surface of the flap plate 75 as shown in FIG. 78, the plate surface 78 is bent into a concave curved surface shape by the wind pressure. The airflow X3 flows along the concave curved plate surface 78, so that the air blowing direction is smoothly changed, and the airflow X3 is blown out in the left and right outer directions. In this case, the blowing direction is changed from the forward direction to the angle B, and the angle B is larger than the angle A.

Specifically, each vertical flap body 85 </ b> A has a flap plate 75 in which substantially the entire area of the plate surface 78 other than the rotating shaft 76 and the connecting shaft 77 at both ends is spanned between the rotating shaft 76 and the connecting shaft 77. Therefore, each vertical flap body 85A is deformed into a smooth shape by wind pressure over the entire area. The airflow X3 is pushed away by the wind pressure, and the plate surface 78 is deformed into a concave curved surface shape. The shape of the concave curved surface is determined so that the elastic force of the flap plate 75 and the wind pressure are balanced, and the airflow X3 is easy to pass through. Adjusted naturally.
Further, the flap plate 75 is deformed into a concave curved surface shape as shown in FIG. 6B, so that the inclination angle is larger on the outer side in the width direction than in the case where the flap plate 75 is not deformed as shown in FIG. As a result, the blowing direction becomes an angle B larger than the angle A.

That is, each flap plate 75 is deformed into a concave curved surface shape by the wind pressure, so that the ventilation resistance is reduced and the inclination angle is increased outward in the width direction. As a result, the vertical flap 85 can blow air over a wider range, and the vertical flap 85 can reduce the airflow resistance when changing the direction of the wind. In this way, since each flap plate 75 is deformed into a concave curved surface shape, the ventilation resistance does not increase even if the magnitude of the change in the angle of the air blowing in the vertical flap 85 is increased. Air can be blown to a large angle where air cannot be blown.
Moreover, in 1st Embodiment, since the right side flap 72 and the left side flap 71 are independently arrange | positioned at the right and left of the blower outlet 13, and can change a wind direction to the outer side independently from right and left, it can blow in a wide range. it can.
Although not shown, when the air flow rate of the blower fan 31 is medium in the state of FIG. 6A, each vertical flap body 85A is deformed into a concave curved surface shape substantially by the wind pressure. In this case, the amount of deformation of the flap plate 75 is smaller than that when the airflow is strong, and the inclination angle of the flap plate 75 is smaller than when the airflow is strong. The size is between.

When the controller 58 receives an instruction to blow air widely in the width direction, it drives a vertical flap drive motor (not shown) to incline the right flap 72 and the left flap 71 outward in the width direction and The air volume of the fan 31 is increased. Thereby, since each flap board 75 of the right side flap 72 and the left side flap 71 is deformed into a concave curved surface shape by the wind pressure as shown in FIG. 6B, it is possible to blow air in a wider range in the width direction and to reduce the ventilation resistance. , Can blow farther. Thereafter, when detecting that the room temperature has reached the target value, the control unit 58 reduces the air volume of the blower fan 31 and returns the directions of the right flap 72 and the left flap 71 to the inner side in the width direction.
Here, the instruction that the air is blown widely in the width direction is an instruction that is issued when it is desired to distribute the conditioned air over a wide range in the room. For example, the control unit 58 determines itself when starting the operation of the indoor unit 12. Or may be an instruction by a user's operation of a remote controller (not shown).

  If you want to change the wind direction to any direction, adjust the wind direction by changing the direction of the vertical flap 85 with the remote controller while the user is receiving the wind instead of adjusting the direction of the vertical flap 85. it can. That is, by adjusting the wind direction while receiving the wind, the wind direction can be adjusted in an arbitrary direction even with the vertical flap 85 that is deformed into a curved surface.

As described above, according to the first embodiment, the flap plate 75 as the flexible portion provided in the substantially entire region of the plate surface 78 of the vertical flap 85 is deformed by the wind pressure of the blown air, and the wind pressure state Accordingly, the shape is smoothly deformed into a concave curved surface shape so as to follow the flow of the wind, so that the air blowing direction further spreads left and right and the ventilation resistance is reduced. Thus, the vertical flap 85 can blow air in a wider range in the left-right direction and can blow air far.
In addition, since the flap plate 75 of the vertical flap 85 that is rotated left and right around the rotation shaft 76 smoothly deforms into a concave curved surface shape along the flow of wind, it can blow air over a wider range, The ventilation resistance at the time of changing a wind direction with the vertical flap 85 can be reduced, and it can blow to far.

In addition, since the flap plate 75 provided in substantially the entire region between the one end 75A and the other end 75B is smoothly deformed into a concave curved surface shape along the flow of the wind, it is possible to blow air over a wider range, and the vertical flap The ventilation resistance at the time of changing a wind direction by 85 can be reduced, and it can blow to far.
Furthermore, since the flap plate 75 spanned between the rotating shaft 76 at one end 75A and the connecting shaft 77 at the other end 75B has a concavely curved surface shape so as to follow the flow of wind, a wider range. In addition to being able to blow air, it is possible to reduce the ventilation resistance when changing the wind direction with the vertical flap 85 and to blow farther.

Furthermore, the plurality of vertical flap bodies 85A can be rotated in conjunction with the slide plates 73A and 73B that slide to the left and right, and the wind direction can be changed.
Moreover, when the control part 58 receives the instruction | indication which ventilates widely in the width direction, while making the vertical flap 85 incline outward in the width direction, and increasing the air volume of the ventilation fan 31 of the indoor unit 12, The flap plates 75 of the flap 72 and the left flap 71 are deformed into a concave curved surface shape by wind pressure. For this reason, while being able to blow in a wider range by the width direction, ventilation resistance can be reduced and it can blow farther.

  In addition, the said 1st Embodiment shows the one aspect | mode which applied this invention, Comprising: This invention is not limited to this. In the said embodiment, although the example which applied this invention to the indoor unit 12 of the wall-hanging type air conditioning apparatus 1 was demonstrated, this invention is not restricted to this, A ceiling embedded type air conditioning apparatus, a ceiling suspended type The present invention can also be applied to other forms of air conditioning apparatus such as an air conditioning apparatus.
