  The air conditioner indoor unit 10 shown in FIG. 1 is attached to an indoor wall surface or the like. The surface attached to the wall surface of the air conditioning indoor unit 10 is the back surface (rear surface). The air conditioning indoor unit 10 includes a casing 20, an air filter 30, a first horizontal flap 41, and a second horizontal flap 42.

(2) Detailed Configuration of Air Conditioning Indoor Unit 10 (2-1) Appearance of Casing 20 The casing 20 has a rectangular parallelepiped box shape that is elongated in the lateral direction (left and right direction) of the air conditioning indoor unit 10. The casing 20 surrounds the interior space by the top surface portion 21, the front plate 22, the back plate 23, the right side plate 24, the left side plate 25, and the bottom surface portion 26 of the air conditioning indoor unit 10. That is, the surfaces of the top surface portion 21, the front plate 22, the back plate 23, the right side plate 24, the left side plate 25 and the bottom surface portion 26 are outer surfaces exposed to the indoor space. The top surface portion 21 is formed with a top surface suction port 16 for sucking room air. The front plate 22 constituting the front of the air conditioning indoor unit 10 has its upper end rotatably supported on the top surface portion 21 by a hinge (not shown). The right side plate 24 and the left side plate 25 constitute a right side surface and a left side surface of the air conditioning indoor unit 10, respectively. The back plate 23 constitutes the back surface of the air conditioning indoor unit 10. And the bottom face part 26 constitutes the bottom face of the air conditioning indoor unit 10 together with the first horizontal flap 41 and the second horizontal flap 42.

(2-2) Internal Configuration of Casing 20 FIG. 6 shows a cross section taken along line II in FIG. As shown in FIG. 6, an air filter 30, an indoor heat exchanger 31, an indoor fan 32, a plurality of vertical flaps 33, and an automatic cleaning mechanism 34 are accommodated in the three-dimensional space of the casing 20.

  The bottom surface portion 26 is formed by a bottom frame 28, and the bottom frame 28 is fixed to the back plate 23. Before and after the indoor fan 32, a drain pan 28f that receives dew condensation is provided below the indoor heat exchanger 31. The bottom frame 28 is a member for supporting the indoor heat exchanger 31, the indoor fan 32, the plurality of vertical flaps 33, the first horizontal flap 41, and the second horizontal flap 42. The bottom frame 28 constituting the bottom surface portion 26 of the air conditioning indoor unit 10 is formed with a blowout opening 17 for blowing out conditioned air and a lower surface suction port 18 for sucking in indoor air. The lower surface suction port 18 can be opened and closed by an opening / closing plate 29. The opening / closing plate 29 is driven by a motor M3 controlled by the control device 60 shown in FIG.

  A plurality of vertical flaps 33 and a plurality of first horizontal flaps 41 and second horizontal flaps 42 are rotatably attached to the bottom frame 28. The plurality of vertical flaps 33 are arranged side by side in the left-right direction, and are provided in the blow-out flow path 28b to adjust the wind direction in the left-right direction of the conditioned air to be blown out. Further, a first horizontal flap 41 and a second horizontal flap 42 are disposed downstream of the vertical flaps 33, and the first horizontal flap 41 and the second horizontal flap 42 adjust the wind direction in the vertical direction. The bottom frame 28 has a tongue portion 28 e obliquely below the front of the indoor fan 32. When the indoor fan 32 is driven by the fan motor M5 shown in FIG. 7, an air flow is generated that passes through the indoor fan 32 from the top to the bottom and runs from the top to the bottom of the indoor fan 32. As a result, the indoor air is sucked in from the top surface suction port 16 or both the top surface suction port 16 and the bottom surface suction port 18 and passes through the indoor heat exchanger 31. An airflow indicated by a broken arrow C that is blown from the fan 32 through the blowout flow path 28b and blown into the room from the blowout opening 17 is generated.

The control device 60 is connected to the memory 62, and data related to the control sequence is stored in the memory 62. Further, the memory 62 stores data such as detection results transmitted from the indoor state detection sensor unit 50 to the control device 60. In addition, the control device 60 receives a command for the air conditioning indoor unit 10 transmitted from the remote controller 61, and controls the air conditioning indoor unit 10 according to the command. Then, the control device 60 notifies the user of information such as the state detected by the indoor state detection sensor unit 50 by using the remote controller 61 or the like.

(3) Indoor state detection sensor unit (3-1) Arrangement position of indoor state detection sensor unit The indoor state detection sensor unit 50 (hereinafter also referred to as sensor unit 50) is a general term for various sensor units, For example, a human detection sensor that detects a person and a temperature sensor that detects a temperature are included. Various detection methods can be employed for the sensor used in the sensor unit 50. For example, an infrared sensor that detects infrared rays, a radiation sensor that detects radiant heat, and a CCD image sensor that detects light are used in the sensor unit 50. .

  The sensor unit 50 is installed in the casing 20. The sensor unit 50 detects, for example, a person in the room or detects the floor temperature in the room. For this reason, the sensor unit 50 is provided on the bottom surface part 26 of the outer surface of the casing 20 from the viewpoint of easy detection. It is preferable. In addition, the position of the sensor unit 50 viewed from the viewpoint of ease of detection is preferably the front in the bottom surface portion 26, and is a blowout airflow space FS1 in which air flows in front of the blowout opening 17 (see FIG. 6). It is preferable to arrange in the part facing the surface. The blowout airflow space FS1 shown in FIG. 6 is a space where the air blown from the blowout opening 17 may flow. Depending on the angles of the first horizontal flap 41 and the second horizontal flap 42, the blowout opening 17 is shown. The air blown from the air may flow or may not flow.

  In the air conditioning indoor unit 10 shown in FIG. 5, the sensor unit 50 is installed in a circular mounting opening 26 a formed in the bottom surface portion 26. The attachment opening 26 a is formed on the outer surface of the bottom surface portion 26 formed on the blowout opening 17. A cylindrical space extends from the mounting opening 26 a toward the inside of the casing 20. Since the sensor unit 50 is fitted in a columnar space extending from the mounting opening, the shape of the portion fitted in the columnar space is also a columnar shape. When the air conditioning indoor unit 10 is attached to the vertical wall, the columnar space extending from the attachment opening 26a extends vertically upward. And the sensor unit 50 is comprised so that it can be rotated by the motor M6 (refer FIG. 7) centering on the central axis CA (refer FIG. 8) of this cylindrical space.

  8 and 10 show a part of FIG. 5 in an enlarged manner. 9 shows a cross section cut along the line II-II in FIG. 8, and FIG. 11 shows a cross section cut along the line III-III in FIG. About the bottom face part 26 when the air conditioning indoor unit 10 is attached to a vertical wall, the periphery of the attachment opening 26a into which the sensor unit 50 is fitted is slanted so that the front rises upward and the rear falls downward with respect to the horizontal plane. Leaning on. Moreover, the circumference | surroundings of the attachment opening 26a become the same height along the left-right direction. Therefore, when the sensor unit 50 does not perform detection, the decorative surface 51, which is the lower end surface of the sensor unit 50, is inclined at an angle θ1 with respect to the horizontal plane, like the bottom surface portion 26, as shown in FIG. Yes. And when not detecting, the height of the makeup | decoration surface 51 and the bottom face part 26 also corresponds, and the makeup | decoration face 51 and the bottom face part 26 are flush | level. The state shown in FIGS. 8 and 9 is the first state in which the detection unit has entered the inside of the outer surface of the casing 20.

  When detection by the sensor unit 50 is performed, the sensor unit 50 is in a state where the detection unit 55 protrudes below the bottom surface part 26 as described in FIGS. 10 and 11. That is, the state shown in FIG. 11 is a second state in which the detection unit 55 of the sensor unit 50 protrudes outside the outer surface of the casing 20.

(3-2) Shape of sensor unit The sensor unit 50 has a cylindrical shape whose diameter is slightly smaller than the cylindrical space of the mounting opening 26a. The decorative surface 51 is inclined with respect to the central axis of the cylinder. Therefore, the decorative surface 51 of the sensor unit 50 has a shape formed by an elliptical arc string and an elliptical arc. Accordingly, a part of the side surface of the cylinder of the sensor unit 50 following the chord of the elliptical arc is also flat. The flat portion 52 which is cut out and has a substantially planar shape is inclined by an angle θ2 with respect to the vertical direction in the cross-sectional view shown in FIG. The flat part 52 is provided with a detection part 55. That is, the detection unit 55 is facing diagonally downward. Since the air-conditioning indoor unit 10 is arranged at a relatively high position in the room, it is preferable to face a detection target at a position lower than the detection unit 55 in both cases of detecting a person and detecting the temperature of the floor. Therefore, the direction of the detection unit 55 is set as described above.

(3-3) Detection by Sensor Unit The range detected by the detection unit 55 is, as shown in FIG. 12, the left and right angles θ3 including the center line CL extending perpendicularly to the front surface of the detection unit 55. This is the range of the vertical angle θ4 including the range and the center line CL. In particular, since the left and right detection ranges are limited, the sensor unit 50 is rotated around the central axis CA to move the left and right detection ranges in order to detect the main indoor range that is wider than the left and right detection areas. Is being detected. The motor M6 (see FIG. 7) that drives the sensor unit 50 is, for example, a stepping motor, and the rotating angle is controlled by the control device 60. Therefore, the control device 60 can obtain a detection result of, for example, 180 ° on the front surface that is wider than the range of the angle θ3.

  FIG. 13A shows the on / off timing of the operation of the air conditioning indoor unit 10. FIG. 13B shows on / off timings of driving of the indoor fan 32. FIG. 13C shows the timing of detection by the sensor unit 50. When the air conditioning indoor unit 10 is turned on at time t1, detection by the sensor unit 50 is performed between time t2 and time t3 before the indoor fan 32 is driven. At this time, for example, the sensor unit 50 performs detection while being rotated 360 ° by the motor M6. Therefore, the sensor unit 50 at time t2 and time t3 is in a state where the decorative surface 51 of the sensor unit 50 and the outer surface of the bottom surface portion 26 are flush with each other, as shown in FIG. Between the time t2 and the time t3, as shown in FIG. 11, the detection unit 55 faces the front.

  Thereafter, the driving of the indoor fan 32 is started at time t4, and the driving of the indoor fan is temporarily stopped at time t6, but the sensor unit 50 detects from time t5 after time t4 when the indoor fan 32 starts driving. The detection ends at time t7 after the drive of the indoor fan 32 is stopped. The indoor fan 32 starts to drive at time t8 and stops at time t12. However, when the sensor unit 50 detects from time t9 to time t10 while the indoor fan 32 is driven, The sensor unit 50 may detect between time t11 and time t13 across the time t12 when the drive of the fan 32 is stopped.

  Here, the interval time between time t3 and time t5, the interval time between time t6 and time t9, and the interval time between time t3 and time t5 are detected from time t2 to time t3. It is longer than the time, the time from time t5 to time t7, the time from time t9 to time t10, and the time from time t11 to time t13. That is, during the operation of the air conditioning indoor unit 10, the control device 60 controls so that the time during which the indoor state detection sensor unit 50 is in the first state is shorter than the time during which the indoor state detection sensor unit 50 is in the second state. Yes. Further, the interval time between time t3 and time t5, the interval time between time t6 and time t9, and the interval time between time t3 and time t5 are set to be the same. However, the interval time during which the detection by the sensor unit 50 is not necessarily performed is not necessarily constant, and may be different, or may be set with other regularity. For example, it can be set so that the detection by the sensor unit 50 is performed when the driving of the indoor fan 32 is stopped.

(4) Features (4-1)
As described above, the indoor state detection sensor unit 50 of the air conditioning indoor unit 10 is installed in the casing 20 and disposed on the bottom surface portion 26.

As a result, the outer surface of the bottom surface portion 26 does not interfere with the detection of the indoor state detection sensor unit 50. For example, even if cold air flow or hot air flow is generated in the blowout airflow space FS1, the detection unit 55 protruding outside the outer surface of the bottom surface portion 26 is not adversely affected by the space outside the outer surface. Furthermore, the detection part 55 can be made to enter inside the outer surface at times other than the time of detection, and the appearance design can be prevented from being deteriorated due to the inconspicuousness of the indoor state detection sensor unit 50. As described above, the deterioration of the detection performance of the indoor state detection sensor unit 50 is suppressed, and the appearance of the air conditioning indoor unit 10 is prevented from being damaged.

(4-4)
The indoor state detection sensor unit 50 has a decorative surface 51 exposed to the indoor space. When the decorative surface 51 is in the first state, it takes a parallel posture with respect to the outer surface of the bottom surface portion 26 of the casing 20 disposed around the decorative surface 51. From this, the decorative surface 51 of the indoor state detection sensor unit 50 looks like a part of the outer surface of the bottom surface portion 26 of the casing 20, that is, the decorative surface 51 tends to be recognized as a part of the bottom surface portion 26. Becomes prominent. As a result, the appearance design of the air conditioning indoor unit 10 is less likely to be damaged due to the conspicuous indoor state detection sensor unit 50.

When the indoor state detection sensor unit 50 is in the first state, the decorative surface 51 is flush with the outer surface of the bottom surface portion 26 disposed around the decorative surface 51, so that the decorative surface 51 is placed on the bottom surface portion 26. The appearance is not deteriorated due to the cosmetic surface 51 being conspicuous on the outer surface by being identified with the outer surface. As a result, the design of the appearance of the air conditioning indoor unit 10 can be improved.

(4-6)
The indoor state detection sensor unit 50 is controlled by the control device 60 so that the time taken for the first state is shorter than the time taken for the second state during operation. As a result, the time during which the detection unit 55 protrudes to the outside of the outer surface of the bottom surface part 26 during operation is shortened, and the adverse effect caused by the detection unit 55 protruding to the outside of the outer surface of the bottom surface part 26 is reduced.
