  Hereinafter, an embodiment of an air conditioner of the present invention will be described with reference to the accompanying drawings.

  First, the overall configuration of the air conditioner 1 of the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing an installation state of the air conditioner 1, and FIG. 2 is a longitudinal sectional view of the air conditioner 1 of FIG. Here, FIG.1 and FIG.2 shows the driving | running state in which the suction panel 4 and the blowing panel 22 opened. In addition, the air conditioner 1 of this embodiment is a ceiling embedded type air conditioner.

  The air conditioner 1 includes a housing 30, a fan 8, a fan motor 10, a heat exchanger 9, a filter 11, a cleaning device 5, a panel driving device 7, and the like.

The housing 30 is suspended from an upper wall surface in the ceiling via a suspension bolt 32. The housing body 2 has a rectangular parallelepiped external shape having a depth dimension (a dimension in the front-rear direction) smaller than a width dimension (a dimension in the left-right direction) and a height dimension smaller than the depth dimension. A square hole is formed in the top surface 31 at a position matching the bottom surface of the housing body 2. In a house where the dimension from the indoor ceiling surface to the rough floor surface of the upper surface in the ceiling is short, it is strongly desired that the height of the housing 30 is particularly small. It becomes the composition which can respond. Note that the front, rear, left and right in the air conditioner 1 of the present embodiment have the air outlet as the front side with reference to a standard installation example.

  The decorative panel 3 is disposed so as to cover the lower surface opening of the housing body 2 and the edge of the hole of the top surface 31 and to be exposed below the ceiling surface 31. The decorative panel 3 has a rectangular shape larger than that of the housing body 2 when viewed from above, and is attached to the housing body 2. The decorative panel 3 constituting the lower surface of the housing 30 is provided with an air inlet 30a and an air outlet 30b. The air suction port 30 a is provided long in the left and right in the rear part of the decorative panel 3, and the air outlet 30 b is provided in the left and right in the front part of the decorative panel 3.

The fan 8 is a cross-flow fan that is long in the left-right direction. The fan motor 10 that drives the fan 8 is juxtaposed on one side of the fan 8 in the left-right direction, and the rotation shafts of the fan 8 and the fan motor 10 are connected to each other. In FIG. 2, the fan motor 10 is shown together with the fan 8 so as to represent the positional relationship between them, but in reality, the space in which the fan motor 10 is arranged is partitioned by the ventilation path of the fan 8 and the partition plate. .

  The decorative panel 3 includes a suction panel 4 that opens and closes the air suction port 30a and a blowout panel 22 that opens and closes the air blowout port 30b. The suction panel 4 and the blow-out panel 22 are driven by the panel drive device 7 so that the air suction port 30a is opened when the air conditioner 1 is operated and the air suction port 30a is closed when the operation is stopped. The driving operation of the panel driving device 7 is controlled by a control device (not shown). With such a configuration, it is possible to perform predetermined ventilation during the air conditioning operation, and it is possible to prevent indoor air from entering the housing when the operation is stopped and contaminating the interior with dust in the indoor air. Since the suction panel 4 itself does not have a ventilation opening, it is good in design.

  The suction panel 4 is pivotally supported at the front side and supported at the lower end of the panel lift arm 71 and rotated by the vertical movement of the panel lift arm 71. The air suction port 30a is opened and closed by the rotation of the suction panel 4. The panel lifting / lowering arm 71 is moved up and down by an arm panel driving device 72 (see FIG. 4) of the panel driving device 7.

  Furthermore, the suction panel 4 includes a single strip-shaped synthetic resin panel member 41 that opens and closes the air suction port 30a and a metal reinforcing plate 42 combined with the panel member 41 as main components. . By using the reinforcing plate 42, the strength of the suction panel 4 can be improved. By supporting the reinforcing plate 42 with the arm 7 and rotating the panel member 41 via the reinforcing plate 42, the reliability of the suction panel 4 can be maintained.

  The blowout panel 22 is rotatably supported at the rear side, and is rotated by the blowout panel drive motor. This blowing panel 22 also serves as a blowing wind direction plate that raises and lowers the wind direction, and the wind direction sent into the room can be adjusted by adjusting the opening / closing angle of the blowing panel 22. The blow-out panel 22 is driven so as to blow mainly the wind forward from the air outlet 30b during cooling, and mainly blow the wind downward during heating by controlling the blow-panel drive motor with a control device.

  The suction panel 4 and the blowout panel 22 are installed with a lower surface continuous from the lower surface of the central portion of the decorative panel 3. In other words, the lower surface of the front portion and the rear portion of the decorative panel 3 is located above the lower surface of the central portion via the step portion, and the suction panel 4 and the blowout panel 22 are the step portion. It is installed in the space formed by. With such a configuration, the appearance design of the lower surface of the air conditioner can be improved.

  The horizontal dimensions of the suction panel 4 and the blowout panel 22 are the same as each other, and are set to be the same as the horizontal dimension of the decorative panel 3. In other words, the suction panel 4 and the blow-out panel 22 protrude in the left-right direction from the air suction port 30 a and the air blow-out port 30 b and extend to both side ends of the decorative panel 3. From this point, the appearance design of the lower surface of the air conditioner can be improved.

  The heat exchanger 9 is arranged in the ventilation path on the air suction side of the fan 8 in the housing 30. The heat exchanger 9 includes a rear heat exchanger portion 9 a provided on the rear side of the fan 8 and a lower surface heat exchanger portion 9 b provided on the lower surface side of the fan 8. The rear heat exchanger unit 9a is installed with an inclination so that the lower part is located on the front side (fan side) and the upper part is located on the rear side (counter fan side). The lower surface heat exchanger section 9b is installed with an inclination so that the front side thereof is slightly lower.

  By attaching the rear heat exchanger portion 9a and the lower heat exchanger portion 9b with different attachment angles, the heat transfer area as the heat exchanger 9 can be increased, and the performance can be improved. Here, by eliminating the slits of the plate fins of the lower-surface heat exchanger 9b having a small inclination, the flow of condensed water during cooling operation is improved, so that the condensed water accumulates in the slit portion, and the condensed water has a large ventilation. It is possible to suppress the occurrence of problems such as a decrease in air volume and an increase in noise due to resistance.

  By setting the heat transfer area of the back heat exchanger section 9a and the bottom heat exchanger section 9b in response to the small wind speed distribution of the bottom heat exchanger 9b and the large wind speed distribution of the back heat exchanger section 9a. It is possible to optimize the balance between the air volume and the heat transfer area, which is effective for improving performance and reducing noise.

  A lower surface heat exchanger portion 9b continuously extends from the lower end portion of the back surface heat exchanger portion 9a so as to surround the fan 8 downward and forward. With such a configuration, the ventilation area of the heat exchanger 9 can be increased without increasing the height dimension, the heat exchange performance can be improved with low noise, and it is suitable for a ceiling-embedded air conditioner. It has become a thing. Further, a substantially triangular space is formed on the back side of the heat exchanger 9 when viewed from the side.

  The heat exchanger 9 constitutes a part of the refrigeration cycle. The refrigeration cycle is configured to circulate the refrigerant in the order of the compressor, the four-way valve, the outdoor heat exchanger, the pressure reducing device, the heat exchanger 9, the four-way valve, and the compressor. The heat exchanger 9 (the back heat exchanger section 9a and the bottom heat exchanger section 9b) is composed of a large number of plate fins juxtaposed in the left-right direction and a meandering refrigerant pipe that passes through these plate fins. Yes. The width of the ventilation portion of the heat exchanger 9 and the width of the fan 8 are substantially the same.

  The filter 11 collects dust of room air flowing into the heat exchanger 9 and is composed of a frame part and a mesh part. This filter 11 is disposed in the ventilation path on the air suction side of the heat exchanger 9 in the housing 30 and is installed in a stationary state without being moved during cleaning.

  The filter 11 is installed in a substantially triangular space behind the heat exchanger section 9 and is inclined along the inclined surface of the back heat exchanger section 9a. Specifically, the filter 11 is stored in an inclined manner in a space above the air inlet 30a and behind the rear heat exchanger section 9a. With such a configuration, the ventilation area of the filter 11 can be increased without increasing the height of the air conditioner 1, the dust collection performance can be improved with low noise, and the ceiling-embedded air conditioner It is suitable for.

  The cleaning device 5 is disposed in the housing 30 and cleans and collects dust collected by the filter 11. The dust collected on the suction side of the filter 11 is collected on the back side of the filter 11. Clean and collect. With such a configuration, dust can be cleaned and collected using the space on the back side of the inclined filter 11 without increasing the height of the air conditioner 1, which is suitable for a ceiling-embedded air conditioner. It has become.

  The cleaning device 5 includes a cleaning unit 51 that moves along the filter 11 to clean the filter 11 and a cleaning drive unit 52 that drives the cleaning unit 51 as a unit. The cleaning unit 51 includes a dust box 53. The dust box 53 temporarily collects dust cleaned from the filter 11 by the cleaning unit 51. With such a configuration, dust collected by the filter 11 can be collected while the filter 11 is stationary, and dust can be efficiently cleaned and collected.

  The panel drive device 7 is disposed in the housing 30 and drives the suction panel 4. The control device controls the suction panel 4 to open during operation and close the suction panel 4 when operation stops.

  As shown in FIG. 2, the panel driving device 7 is installed on the front side in the horizontal direction with respect to the fan 8, the heat exchanger 9, and the filter 11. As shown in FIG. 2, the suction panel 4 is opened and closed by a panel drive device 7 disposed at a position farthest from the rotation axis of the suction panel 4 inside the housing body 2. As a result, the motor torque required for opening and closing the suction panel 4 can be minimized.

  The panel drive device 7 is composed of a plurality of panel drive devices installed in the left-right direction of the suction panel 4. In this embodiment, the left panel drive device and the right panel installed above both sides of the suction panel 4. It consists of a drive device. By installing the panel driving device 7 vertically in the empty space on the suction port side, the panel driving device 7 can be housed in the housing main body 2 without obstructing ventilation. There is no problem of high dimensions.

  When the air conditioner 1 is operated, the compressor is driven to operate the refrigeration cycle, the panel driving device 7 is driven, the suction panel 4 is rotated to open the air suction port 30a, and the blowout panel drive motor is operated. When driven, the blowout panel 22 rotates to open the air outlet 30b, and the fan motor 10 is driven to rotate the fan 8. These operations are controlled by the control device.

  By the rotation of the fan 8, room air is sucked into the housing 30 through the air suction port 30 a and passes through the filter 11. At this time, dust contained in the room air is collected by the filter 11. The room air that has passed through the filter 11 is subjected to air conditioning such as heating, cooling, and dehumidification by the heat exchanger 9, and is blown out through the fan 8 to the indoor space again from the air outlet 30b.

  Next, the configuration and operation of the panel driving device 7 will be specifically described with reference to FIGS. 3 to 6. 3 is an exploded perspective view of the panel drive device of FIG. 2, FIG. 4 is an enlarged perspective view of the suction portion of the air conditioner of FIG. 2, and FIG. 5 is a perspective view of the suction portion of the air conditioner of FIG. FIG. 6 is a perspective view of the panel raising / lowering arm shown in FIG. 4.

  The panel driving device 7 includes a panel lifting arm 71 that supports the rear side of the suction panel 4 and an arm lifting mechanism 72 that rotates the rear side of the suction panel 4 by moving the panel lifting arm 71 up and down. It is configured vertically. The panel elevating arm 71 and the arm elevating mechanism 72 are arranged adjacent to each other in the horizontal direction with the suction panel 4 closed. As a result, the panel driving device 7 becomes compact and the storage property is good.

  The panel driving device 7 is disposed in the vicinity of the outer end of the suction panel 4 away from the rotation axis of the suction panel 4 and moves the panel lifting arm 71 up and down in the vertical direction. As a result, the torque of the lifting mechanism motor 72a can be reduced.

  The panel raising / lowering arm 71 is comprised by the arm divided into two up and down, and consists of the 1st arm 71a which is an upper arm, and the 2nd arm 71b which is a lower arm. The first arm 71a and the second arm 71b are connected via connecting means whose connection length can be manually changed. In this embodiment, the connecting means includes a male screw portion 71c provided protruding from the lower end surface of the first arm 71a and a female screw portion (not shown) provided recessed from the upper end surface of the second arm 71b. It is configured.

  By providing such a connecting means, when the air suction port 30a is closed by the suction panel 4, if a gap is generated on either the left or right side, the height of the panel lifting arm 71 is adjusted by the connecting means. The gap can be eliminated. That is, when the decorative panel 3 is attached to the housing body 2, if the ceiling surface 31 is distorted or slightly tilted, the decorative panel 3 is affected, and when the suction panel 4 is closed, In some cases, the gaps of the gaps are not uniform. At such time, the gap between the decorative panel 3 and the suction panel 4 can be evenly suppressed by rotating the first arm 71 a and finely adjusting the total length of the arm 71.

  The arm elevating mechanism 72 includes an elevating mechanism motor 72a having a rotating shaft 72a1 vertically, an elevating mechanism worm gear 72b rotated by a vertical axis as the rotating shaft 72a1 of the elevating mechanism motor 72a rotates, and the elevating mechanism. An elevating mechanism body 72c having an elevating mechanism rack gear 72d that meshes with the worm gear 72b, a square shaft 72f, a coupling tool 72g, and a worm guide 72h are provided.

  The elevating mechanism motor 72a is fixedly disposed on the elevating mechanism main body 72c with a bolt 72e, and the rotation shaft 72a1 projects downward. The lifting mechanism main body 72 c is fixed to the housing main body 2.

  The lifting mechanism worm gear 72b is linked to the rotation shaft 72a1 via a square shaft 72f and a connector 72g. The square shaft 72f is fixed to the rotation shaft 72a1 via the connector 72g, and is rotated along with the rotation of the rotation shaft 72a1. The square shaft 72f and the rotation shaft 72a1 are connected by the same axis. The square shaft 72f is installed so as to extend in parallel with the lifting mechanism rack gear 72d.

  At the center of the lifting mechanism worm gear 72b, there is a square hole 72b1 slightly larger than the outer shape of the square shaft 72f, and the square shaft 72f is loosely fitted in the square hole 72b1. As a result, the lifting mechanism worm gear 72b is moved up and down while being guided by the square shaft 72f.

  When the elevating mechanism worm gear 72b meshes with the elevating mechanism rack gear 72d and moves up and down, the load on the elevating mechanism worm gear 72b side is supported by the elevating mechanism rack gear 72d, in other words, supported by the housing body 2. Thus, the load on the lifting mechanism motor 72a can be reduced, and the motor torque can be reduced.

  The lifting mechanism worm gear 72b is rotatably mounted on the worm guide 72h. The first arm 71a is rotatably connected to the worm guide 72h via a connecting screw 71d.

  The lower end of the second arm 71b has a rotation axis parallel to the rotation axis of the suction panel 4, and is rotatably attached to the reinforcing plate 42 of the suction panel 4. The upper end of the first arm 71a is the suction panel. 4 has a rotation axis parallel to the rotation axis 4 and is rotatably attached to the lifting mechanism worm gear 72b via a worm gear guide 72h. With such a configuration, the vertical movement of the lifting mechanism worm gear 72b can be converted into the rotational movement of the suction panel 4.

  The reinforcing plate 42 is formed of a frame member that is pressed from a metal flat plate and has a frame portion and a hole, and extends long along the longitudinal direction of the panel member 41.

  The suction panel 4 can be opened when the air conditioner 1 is operated or when maintenance is performed on the inside of the housing body 2.

  When the air conditioner 1 receives the operation command, the control device opens the suction panel 4 by rotating the lifting mechanism motor 72a. That is, when the lifting mechanism motor 72a is rotated, the square shaft 72f and the lifting mechanism worm gear 72b are rotated, and the lifting mechanism worm gear 72b is moved downward by meshing with the lifting mechanism rack gear 72d. The connected panel member 41 is opened.

  The opening angle and opening / closing speed of the suction panel 4 are determined by the rotation time and rotation speed of the lifting mechanism motor 72a, and can be easily changed by changing the command data from the control device.

  The torque of the elevating mechanism motor 72a is required when the suction panel 4 is moved, but is held by meshing of the elevating mechanism worm gear 72b and the elevating mechanism rack gear 72d when stopped, so that the elevating mechanism motor 72a has a holding force. There is almost no need, and the suction panel 4 can be held in a stopped state. This is because the lifting mechanism worm gear 72b moves in the vertical direction while the lifting mechanism motor 72a rotates in the horizontal direction of the vertical axis.

  The opening degree of the suction panel 4, in other words, the lower stop position of the lifting mechanism worm gear 72b is determined by the number of feed pulses of the lifting mechanism motor 72a. The number of feed pulses is controlled by the control device. Thereby, the opening degree of the suction panel 4 can be determined easily.

  Further, when the suction panel 4 is closed, the suction panel 4 can be closed by rotating the lifting mechanism motor 72a in the reverse direction of opening and moving the lifting mechanism worm gear 72b upward.

  If a large gap is formed between the suction panel 4 and the decorative panel 3 when the suction panel 4 is closed, a design problem occurs. Therefore, as shown in FIG. 4, the limit switch 14 is provided on the decorative panel 3 side. It has. When the limit switch 14 is pressed when the suction panel 4 is closed, the rotation of the lifting mechanism motor 72a is stopped and the suction panel 4 is stopped. As a result, the suction panel 4 stops at a certain gap with respect to the decorative panel 3. By using the limit switch 14, the gap between the decorative panels 3 can be minimized, and the retightening operation by the lifting mechanism motor 72a is not required. As a result, it is possible to suppress vibration noise, squealing noise, and the like that are generated during retightening by the lifting mechanism motor 72a. The retightening operation by the lifting mechanism motor 72a is to apply an extra feed pulse to the lifting mechanism motor 72a so that the suction panel 4 does not generate a large gap in the decorative panel 3, and in many cases the suction panel 4 4 collides with the decorative panel 3, and a large load is applied between the suction panel 4 and the lifting mechanism motor 72a.

  Next, the removal of dust from the dust box 53 of the cleaning device 5 will be described with reference to FIGS. 7 is a diagram for explaining a method of opening the suction panel when dust is removed by the cleaning device of FIG. 2, FIG. 8 is a diagram for explaining a method of sucking out the dust of the cleaning device of FIG. 2 using a vacuum cleaner, and FIG. It is an expansion perspective view explaining the method of sucking up the dust of the cleaning device of 2 using a vacuum cleaner.

  The arm 71 is attached to the reinforcing plate 42, and the reinforcing plate 42 and the panel member 41 are connected by a plurality of latches 17 provided in the left-right direction. By supporting the suction panel 4 with the plurality of latches 17, the weight of the panel member 41 can be dispersed and supported by the reinforcing plate 42. The latch 17 includes a female portion provided on the reinforcing plate 42 and a male portion provided on the panel member 41. By pushing the panel member 41 toward the reinforcing plate 42, the connection between the female portion and the male portion of the latch 17 is released. Moreover, the female part and male part of the latch 17 are connected by pushing the released panel member 41 to the reinforcing plate 42 side.

  The reinforcing plate 42 has a rotation axis that is the same axis as the suction panel opening / closing axis 4 a of the panel member 41, and performs an opening / closing operation together with the panel member 41 in accordance with the movement of the arm 71.

  The flat panel member 41 has a heavy panel weight, and is prone to problems such as swells due to warpage and installation conditions during molding. The panel member 41 is fixed to the reinforcing plate 42 at a plurality of locations. The sled can be minimized.

  When removing dust in the dust box 53, it is desirable to use a dedicated adapter 18 that can be attached to a general vacuum cleaner. The adapter 18 has a contact portion 18a and a suction port portion 18b. The adapter 18 is used to abut the abutting portion 18 a against the lower surface of the panel member 41 and push the panel member 41 to release the latch 17. The adapter 18 crosses the abutting portion 18a and abuts against the reinforcing plate 20, inserts the suction port portion 18b into the dust outlet 53a of the dust box 53, and further pushes the damper 53b into the dust box 53 to enter the dust box 53. Used to suck up dust in 53. By using the adapter 18 in this way, dust in the dust box 53 can be sucked up very easily.

  Specifically, a method for removing dust in the dust box 53 will be described. First, the adapter 18 is attached to the tip of the handle 19 of the vacuum cleaner, and then the panel member 41 is opened. Push to release all latches 17 as shown in FIG. When all the latches 17 are released, the panel member 41 is uncoupled from the reinforcing plate 42, and is rotated about the suction panel opening / closing shaft 4a by the load of the panel member 41 itself to be fully opened. As a result, the dust outlet 53a provided on the lower surface of the dust box 53 is exposed directly below. Since the reinforcing plate 42 is supported by the arm 72, it remains on the air inlet 30a side of the decorative panel 3, but the dust outlet 53a is exposed directly below through the hole portion of the reinforcing plate 42.

  The reason why the panel member 41 and the reinforcing plate 42 are separated and rotated is as follows. When the suction panel 4 is driven by the operating arm 71, the opening angle of the suction panel 4 is determined by the length of the arm 71 and the distance from the suction panel opening / closing axis 4 a to the support point of the arm 71. In order to increase the opening angle of the suction panel 4 while increasing the distance from the suction panel opening / closing shaft 4a to the support point of the arm 71 to reduce the motor torque, it is necessary to increase the length of the arm 71. In this case, there arises an inconvenience that the height of the housing 30 must be increased and the arm 71 must be accommodated in the housing 30. Further, if the opening angle of the suction panel 4 is increased while shortening the length of the arm 71 to reduce the height dimension of the housing 30, the distance from the suction panel opening / closing shaft 4 a to the support point of the arm 71 is increased. It needs to be small. In this case, there arises a disadvantage that the motor torque must be increased. In this embodiment, the above-described inconvenience can be solved by adopting a configuration in which the panel member 41 and the reinforcing plate 42 described above are separated and rotated.

  Next, the direction of the adapter 18 is rotated 90 degrees, and one of the adapters 18 is hooked on the cross reinforcing plate 20 in the suction portion of the decorative panel 3. At this time, the damper 53b portion of the dust box 53 moves to the position of the dust outlet 53a of the adapter 18 and crosses one side of the adapter 18 to the reinforcing plate 20, and the other end is inserted into the damper 53b portion of the dust box 53. In the state, the dust in the dust box 53 is sucked out by the vacuum cleaner.

  The reason why the adapter 18 is crossed over the reinforcing plate is to prevent the dust box 53 from being damaged when the dust box 53 is pressed with the handle 19 of the vacuum cleaner with the adapter 18 and excessive force is applied to the dust box 53. is there.

  When the dust suction is completed, the adapter 18 is removed from the dust box 53, the adapter 18 is rotated 90 degrees, the latches 17 of the suction panel 4 are pushed, and all the latches 17 are locked, whereby the suction panel 4 is closed.

  Thus, by attaching the adapter 17 to the handle 19 of the vacuum cleaner, there is no danger of working on a hill, and the work can be performed safely. Temporarily, when the suction panel 4 is fully closed, the service method when a failure occurs, all the latch 17 part of the suction panel 4 is opened, and after the suction panel 4 is fully opened, from the joint part of the arm 71, The maintenance work can be performed by separating the first arm 71a and the second arm 71b and fully opening the reinforcing plate 42 together.

  Next, the blowout panel 22 will be described with reference to FIGS. 10 and 11. 10 is a perspective view of the decorative panel of FIG. 1 as viewed from below, and FIG. 11 is an enlarged perspective view of a light receiving portion of the decorative panel of FIG.

  In the blowing part of the decorative panel 3, a blowing panel 22 and a vertical blade 21 are installed between the blowing panel 22 and the fan 8 for spreading the wind to every corner of the room. The blowout panel 22 performs blowing in the perspective direction, and the vertical blade 21 performs blowing in the left-right direction.

  Since the blowout panel 22 has a role of guiding the wind along the panel serving as a horizontal blade, it is ideal to have a large area. The blowout panel 22 can be efficiently sent to the far and near sides along the blades by taking the blower panel 22 to the end 23 of the decorative panel 3 in both the short and long directions.

  The blown-out wind is blown out in different directions by the blow-out panel 22, but if the blade width is small, wind turbulence or entrainment occurs, and the wind does not flow far away as expected. By taking the blowout panel 22 large up to the position of the panel end 23, it is possible to suppress the entrainment of the wind and smoothly send the wind far away.

  The blowing panel 22 has an effect of smoothly blowing the wind in the left-right direction by increasing not only in the width direction but also in the longitudinal direction, and the longitudinal direction of the blowing panel 22 extends to the end 23 of the decorative panel 3. By setting the length, the flow of wind in the left-right direction can be made smooth.

  Further, in order to eliminate the turbulence and entanglement at the corner of the air outlet 30b that occurs when the air is blown to the left and right, an inclined surface 24 that guides the wind obliquely is provided at the corner of the air outlet 30b. It realizes a smooth wind flow without entrainment.

  When the blowout panel 22 is enlarged, the flow of wind is smoothly blown out. However, since the area where the light receiving part 26 is hidden is increased by the blowout panel 22, the blowout panel 22 is closed when the blowout panel 22 is closed or during cooling operation. The light receiving portion 26 is arranged in the longitudinal direction of the blow-out panel 22 so that light can be received even in a state where is facing downward.

  At this time, when the U-shaped notch 25 is provided in the part of the blowout panel 22 that hinders reception of the light receiving unit 26, the blowout panel 22 may completely hide the light receiving unit 26 when stopped. Even when the position of the blowing panel 22 during operation conceals the light receiving portion, light can be received through the U-shaped cutout 25.

  The light receiving element 27 needs to have a structure that cannot be directly seen from the viewpoint of design, and by providing light receiving covers 28 at a total of two locations of the blowout panel 22 and the decorative panel 3, the light receiving element 27 cannot be directly seen.

  When the light receiving cover 28 is attached to the blowout panel 22, it is general that the blowout panel 22 has a structure in which a square hole is formed in an island shape to improve the flow of the resin. Therefore, the blowout panel 22 serving as a horizontal blade is formed as a cutout 25 cut out to the end in a U-shape.
