Change the gas flow. As described above, by using the shape-variable louver that has flexibility and can be changed in shape, the flow of gas such as the wind direction can be easily changed with a simple configuration.

  Further, in the gas flow adjusting mechanism, since the variable shape louver is made of a cloth member, the shape in the gas flow path can be easily changed.

  According to at least one of the above-described configurations, the air conditioner has a shape-variable louver that is provided at the air outlet of the conditioned air and has a flexible shape that can be changed. This variable shape louver has a position on one end fixed to the outlet, and the other end is moved and driven by a drive mechanism relative to one end, which is a fixed end, to change the shape in the outlet. Change the air direction of the air at the outlet. As described above, by using the shape-variable louver that has flexibility and can be changed in shape, the air direction at the outlet can be easily changed with a simple configuration.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, an indoor air conditioner arranged on the ceiling of a building will be described as an example to which the gas flow adjusting mechanism is applied. However, this is an example for explanation, and the air conditioner is arranged at a place other than the ceiling. It may be a device. For example, it may be a wall-mounted air conditioner provided on the inner side wall of a building, or a floor-mounted air conditioner that is placed on an indoor floor and has a suction port and an outlet in a direction perpendicular to the floor surface. Moreover, the separation type air conditioner which arrange | positions the grille provided with a suction inlet and a blower outlet in a room, and arrange | positions a heat exchanger part in a place different from a grill may be sufficient. Moreover, as a gas flow adjustment mechanism, you may use other than the air-conditioning equipment which adjusts the temperature etc. of air. For example, gas flow path equipment such as an intake duct and an exhaust duct may be used. Moreover, it is good also as what applies to the flow path through which gas other than air flows depending on the case.

  Moreover, although the suction port is described as a circular shape and the outlet is an annular shape, the outlet may be an annular shape, for example, the inner peripheral shape and the outer peripheral shape of the outlet may be elliptical, Further, the inner peripheral shape and the outer peripheral shape may be polygonal shapes. In short, it may be an annular shape having no corners or corners where the wind does not blow out. Note that the outer shape of the decorative panel itself may have any shape. The suction port may have a shape other than a circular shape. For example, an elliptical shape or a polygonal shape including a quadrangular shape may be used.

  Below, the same code | symbol is attached | subjected to the same element in all the drawings, and the overlapping description is abbreviate | omitted. In the description in the text, the symbols described before are used as necessary.

  FIG. 1 is a diagram illustrating the structure of an indoor air conditioner 10 arranged on the ceiling of a building as an exploded view. The indoor air conditioner 10 includes a cylindrical device body 12, a cylindrical turbofan 14 disposed in the device body 12, a heat exchanger 16 disposed around the turbofan 14, and a heat exchanger 16. A refrigerant pipe 18 to be connected, an annular drain pan 20 disposed so as to receive the bottom surface of the heat exchanger 16, a decorative panel 22 and a suction grill 24 provided on the ceiling surface covering these from the design surface Consists of including. A suction port 26 is provided at the center of the suction grill 24, and an annular air outlet 28 is formed between the decorative panel 22 and the suction grill 24. An annular air outlet 28 is formed in the annular air outlet 28. A variable shape louver 30 made of cloth is arranged.

  The indoor air conditioner 10 is connected from the refrigerant pipe 18 to an outdoor heat exchange device (not shown). In the outdoor heat exchange device, a compressor or the like that exchanges heat with the outside air by expanding and compressing the refrigerant is arranged, and thereby the temperature of the refrigerant flowing through the heat exchanger 16 can be adjusted. The indoor air conditioner 10 sucks indoor air from the suction port 26 by the operation of the turbo fan 14, performs heat exchange between the refrigerant and the sucked air by the heat exchanger 16, and adjusts the air to an appropriate temperature. Is returned to the room from the air outlet 28 by the turbo fan 14, thereby adjusting the temperature of the air in the room.

  In addition, the indoor air conditioner 10 has a function of changing the shape of the variable shape louver 30 disposed in the air outlet 28 to change the direction of the flow of air blown into the room, that is, the wind direction. In FIG. 1, two types of solid arrows and dashed arrows are shown as representative examples of the wind direction that is changed by changing the shape of the variable shape louver 30.

  Among the elements of the indoor air conditioner 10, the contents of the apparatus main body 12, the turbo fan 14, the heat exchanger 16, the refrigerant pipe 18, and the drain pan 20 are the same as those conventionally used for ceiling-mounted indoor air conditioners. Therefore, detailed description is omitted. Here, since the turbo fan 14 has a cylindrical shape, the air flow is basically sucked in a direction parallel to the axis of the turbo fan 14 and is omnidirectional from the cylindrical outer periphery of the turbo fan 14. Air will flow out.

  Hereinafter, the decorative panel 22, the suction grille 24, the shape-variable louver 30, the suction port 26, and the air outlet 28 will be mainly described. FIG. 2 is a cross-sectional view showing portions of the indoor air conditioner 10 relating to the decorative panel 22, the suction grille 24, and the variable shape louver 30. FIG. 3 is a schematic diagram for explaining an example of the shape change of the shape-variable louver 30. 4 and 5 are cross-sectional views for explaining how the flow of air from the air outlet 28 is changed by changing the shape of the variable shape louver 30.

  The suction grill 24 is a plastic part having an annular shape, that is, a donut-like shape, as viewed from the inside of the room. This annular shape is matched with the outer shape of the drain pan 20, and has a function of covering the drain pan 20 so that it cannot be seen from the outside. Further, the annular opening on the inner peripheral side is substantially matched with the shape of the opening on the inner peripheral side of the drain pan 20, so that the turbo opening passes through the opening on the inner peripheral side of the drain pan 20 from this opening. Air is sucked into the indoor air conditioner 10 by the operation of the fan 14. Therefore, the inner peripheral side opening of the suction grille 24 becomes the suction port 26. The suction port 26 has a circular shape because it corresponds to the inner diameter of the donut shape.

  The decorative panel 22 is a plastic part attached to the ceiling surface 6 and having a circular opening at the center. The opening of the decorative panel 22 is set to such a size that the suction grill 24 is disposed and an annular opening as the outlet 28 is formed around the suction grill 24.

  The variable shape louver 30 is a cloth-made annular loop material. As shown in FIG. 3, the annular loop member has a peripheral length on one end that is one end face that is a fixed end described later, and the other end that is the other end face that is a moving end. Is set so that its length is different. In the example shown in FIG. 3, the peripheral length on one end side is set to be longer than the peripheral length on the other end side. The perimeter may be set longer than the perimeter on one end side.

  When this is in a natural state in an annular shape, it has a shape that is obtained by cutting the top of a conical shape. When the variable shape louver 30 is placed in the air flow, air flows along the outer shape of the variable shape louver 30. For example, air flows along the shape of the top of the conical shape. If this shape is changed, air will flow along the changed shape.

  The term “fabric” means that the material is made of a material having flexibility enough to change its shape, and it can be made of a natural fiber or a synthetic fiber such as a campus cloth. The surface may be subjected to a surface treatment such as an appropriate coating for preventing air from flowing.

  The fixed end 32 provided at a position on one end side of the variable shape louver 30 functions as an invariable end when the variable shape louver 30 changes its shape. Specifically, a rigid support ring is connected around one end side of the annular loop member of the shape-variable louver 30 to fix the shape on one end side of the shape-variable louver 30 to a circular shape. And the inner wall of the opening of the decorative panel 22 can be connected by a fixing member. In this case, the fixing member that fixes the position of the support ring is the fixed end 32.

  As the support ring, a circular ring member having appropriate rigidity, for example, a metal wire formed into a circular shape can be used. As the fixing member, a bar material or the like having appropriate rigidity can be used.

  The moving end 34 provided on the other end side of the variable shape louver 30 is connected to the drive mechanism 36 and functions as a movable end when the variable shape louver 30 changes its shape. Specifically, in the same manner as described in the fixed end portion 32, a rigid support ring is connected around the other end side of the annular loop member of the variable shape louver 30 to connect the other end of the variable shape louver 30. The side shape is fixed to a circular shape, and the support ring and the drive mechanism 36 are connected by a movable member. In this case, the movable member connected to the support ring is the moving end 34.

  As the support ring, the same ring as that used for the fixed end 32 can be used, but the peripheral length on one end side and the peripheral length on the other end side of the variable shape louver 30 are different. The diameter of the support ring used for the moving end 34 is smaller than the diameter of the support ring used for the fixed end 32. Further, as the movable member, a bar material or the like having appropriate rigidity can be used.

  The drive mechanism 36 has a variable shape louver 30 in the vertical direction, that is, in the direction along the axial direction of the circular opening of the decorative panel 22 or in the direction along the axial direction of the circular suction port 26 of the suction grill 24. This is an actuator for moving and driving the moving end portion 34. As described above, since the moving end 34 of the variable shape louver 30 is connected to the support ring, it is sufficient that the drive mechanism 36 has a function of driving the support ring up and down. Can be configured. A small motor, a plunger, or the like can be used as the actuator of the drive mechanism 36, and a mechanism such as a cam or a gear can be added as necessary.

  FIG. 3 shows the shape of the variable shape louver 30 when the moving end 34 is moved to the uppermost position by the drive mechanism 36 and the shape of the variable shape louver 30 when the moving end 34 is moved to the lowest position. It is a figure which shows a mode. For easy comparison, a case where the moving end 34 is moved to the uppermost side in the upper stage of FIG. 3 is indicated by a solid line, and a case where the moving end part 34 is moved to the lowermost side in the lower stage is indicated by a broken line. In addition, a Δ mark is attached to the front side of the variable shape louver 30 so that the front and back sides of the variable shape louver 30 can be seen. In the case of the upper part of FIG. 3, since the front side of the shape-variable louver 30 is visible on the front side of the page, the Δ mark is indicated by a solid line, and the back side of the shape-variable louver 30 is visible on the other side. Is indicated by a broken line.

  As shown in the upper part of FIG. 3, when the moving end portion 34 is moved to the uppermost side, the shape-variable louver 30 has a shape obtained by cutting a top portion of a conical shape having a downward spread. The outer surface of the shape-variable louver 30 is the front surface with a Δ mark.

  On the other hand, when the moving end 34 is moved to the lowermost side, as shown in the lower part of FIG. 3, the shape-variable louver 30 has a shape obtained by cutting the top part of the upwardly spreading conical shape. Become. Here, the shape of the annular loop material of the shape-variable louver 30 is turned upside down with respect to the upper side of FIG. That is, in the lower part of FIG. 3, since the back side of the shape-variable louver 30 is visible on the front side of the paper, the Δ mark is indicated by a broken line, and the front side of the shape-variable louver 30 is visible on the other side of the paper. Therefore, the triangle mark is indicated by a solid line. Furthermore, since the vertical relationship between the one end side and the other end side of the variable shape louver 30 is reversed at the upper and lower stages in FIG.

  As described above, in the variable shape louver 30, the annular loop of the variable shape louver 30 is used when the moving end 34 is moved above and below the fixed end 32. Both the top and bottom relationship of the material and the front and back relationship are reversed. Such a shape change can be made by configuring the variable shape louver 30 with a flexible material such as cloth.

  4 and 5 are diagrams for explaining the state of air flow at the air outlet 28 when corresponding to the upper and lower stages of FIG. 3, respectively. FIG. 4 shows a state in the upper stage of FIG. 3, that is, a case where the shape-variable louver 30 has a shape obtained by cutting a top part of a conical shape that is spread downward, and the air at the outlet 28 at this time goes downward. The flow becomes so wide. On the other hand, FIG. 5 shows a state in the lower stage of FIG. 3, that is, a case where the shape-variable louver 30 has a shape obtained by cutting the top part of the conical shape that is widened upward. The flow will be narrowed down as you go down.

  Therefore, by moving and driving the moving end 34 upward by the driving mechanism 36, the air direction of the air conditioned air from the air outlet 28 can be directed to the outer side with respect to the suction port 26. Conversely, by moving and driving the moving end 34 downward by the drive mechanism 36, the air direction of the conditioned air from the air outlet 28 can be directed toward the inner side with respect to the suction port 26. In this way, the driving mechanism 36 moves and moves the movable end portion 34 of the variable shape louver 30 relative to the fixed end portion 32, and changes the shape of the variable shape louver 30 in the outlet 28. The air direction of the air at the outlet 28 can be changed.

  6 to 8 are views for explaining how the decorative panel 22 having a circular opening and the annular suction grill 24 are attached to the apparatus main body 12 and the ceiling surface 6. FIG. 6 is a diagram illustrating a state in which the indoor air conditioner 10 is looked up from the room, and FIG. 7 is a diagram illustrating a state when the decorative panel 22 and the suction grill 24 are removed from FIG. 6. FIG. 8 is a sectional view. In FIG. 8, the variable shape louver 30 is not shown.

  A thin bar 40 shown in FIG. 6 is a member that fixes and connects the outer periphery of the suction grill 24 and the inner periphery of the decorative panel 22. Thereby, the annular suction grill 24 is integrated with the decorative panel 22. A plurality of thin rod members 40 are provided. In the example of FIG. 6, the suction grille 24 is connected to and supported by the decorative panel 22 by eight thin rod members 40.

  The plate-like connection member 42 is a member used to supplement the support function of the suction grille 24 that is not sufficient for the thin bar 40. The connection member 42 is a member having one end fixed to the outer peripheral portion of the circular opening 8 opened in the ceiling surface 6 and the other end extending toward the suction grill 24. One end side of the connection member 42 is fixedly attached to the apparatus main body 12 with a bolt 54, and the suction grille 24 is connected to the other end side with a bolt 52. The one end side may be fixedly attached to the ceiling surface 6 instead of the apparatus main body 12.

  For this purpose, the suction grill 24 is provided with a bolt through hole 48, and the apparatus body 12 is provided with a screw hole 57. Further, a bolt through hole 55 is provided on one end side of the connection member 42, and a screw hole 53 is provided on the other end side. In this way, the bolt 52 is passed through the bolt through hole 48, and the bolt 52 is screwed into the screw hole 53. A bolt 54 is passed through the bolt through hole 55, and the bolt 54 is screwed into the screw hole 57.

  Further, the protruding portion 44 provided on the other end side of the connecting member 42, that is, on the suction grill 24 side, has a function of positioning and supporting the drain pan 20 on the bottom surface. A fitting portion is provided on the bottom surface of the drain pan 20 corresponding to the protruding portion 44. The drain pan 20 is disposed on the connecting member 42 in a state where the position is determined by fitting the protruding portion 44 of the connecting member 42 into the fitting portion of the drain pan 20. Since the drain pan 20 is made of plastic or the like and has a light mass, the drain pan 20 can be supported and sufficiently supported by the strength of the connection member 42.

  As shown in FIGS. 6 and 7, the number of connecting members 42 is preferably three instead of two. In this case, including the part through which the drain pan 20 and the refrigerant pipe 18 are passed, the part passing the annular air outlet 28 is evenly divided in the circumferential direction, that is, the part divided into four equal parts along the circumferential direction. It is preferable to do. Since the connecting member 42 also has a function of supporting the drain pan 20 as described above, when the condensed water accumulates in the drain pan 20 and has a certain amount of mass, the drain pan 20 has two connecting members 42. Therefore, the number of connecting members 42 is preferably three. Of course, it is good also as three or more depending on the case.

  The bolt through holes 46 provided in the decorative panel 22 are for fixing the decorative panel 22 to the apparatus main body 12 with the bolts 50. For this purpose, the apparatus main body 12 is provided with a screw hole 51. In this way, the bolt 50 is passed through the bolt through hole 46, and the bolt 50 is screwed into the screw hole 51. Note that the decorative panel 22 may be fixedly attached to the ceiling surface 6 instead of the apparatus main body 12.

  In this manner, the annular suction grille 24 is formed while minimizing the turbulence of the air flow at the annular outlet 28 formed by the circular opening of the decorative panel 22 and the annular suction grille 24. It can be arranged inside the circular opening of the decorative panel 22.
