Definitions

  • FIG. 9 is a side view of the air-conditioning-apparatus indoor unit according to Embodiment 1 of the present invention in a downward blowing operation mode.
  • FIG. 12 is an enlarged view illustrating air flows in the vicinity of the infrared sensor in the horizontal blowing operation mode of an air-conditioning-apparatus indoor unit according to Embodiment 3 of the present invention.
  • FIG. 13 is an enlarged view illustrating air flows in the vicinity of the infrared sensor in the horizontal blowing operation mode of an air-conditioning-apparatus indoor unit according to Embodiment 4 of the present invention.
  • the nozzle 28 which constitutes the air outlet 23 , includes the left-right deflectors 7 a and 7 b capable of changing the direction of air blown from the air outlet 23 to the living space in the left-right direction, a left-right deflector driving motor 25 a to be driven to change the orientation of the left-right deflector 7 a , a left-right deflector driving motor 25 b to be driven to change the orientation of the left-right deflector 7 b , an up-down deflector driving motor 24 a to be driven to change the orientation of the up-down deflector 8 a , and an up-down deflector driving motor 24 b to be driven to change the orientation of the up-down deflector 8 b.
  • the rotation speed (air flow rate) of a fan motor 6 a is controlled, and the rotation angle of each of left-right deflector driving motors 25 a and 25 b on the left and right sides is controlled. Additionally, in response to the driving signals output from the output unit 12 d , the rotation angle of each of up-down deflector driving motors 24 a and 24 b on the left and right sides is controlled.
  • the infrared sensor 35 is covered with a casing 36 included in the main body 2 .
  • the infrared sensor 35 and the casing 36 protrude from the design surface of the main body 2 .
  • the infrared sensor 35 is disposed next to the air outlet 23 in the left-right direction (horizontal direction).
  • the infrared sensor 35 which is turned by a motor (not illustrated), can obtain temperature information in a wide range of the indoor space.
  • the large air flow control plate 41 and the small air flow control plate 43 are arranged between the infrared sensor 35 and one end of the left-right deflector 7 b close to the infrared sensor 35 .
  • the large air flow control plate 41 and the small air flow control plate 43 extend upwardly from the upper surface of the up-down deflector 8 b so that the surfaces of these plates face in the left-right direction of the air outlet 23 .
  • the large air flow control plate 41 is disposed at one end (in FIG. 4 , right end) of the up-down deflector 8 b closer to the infrared sensor 35 than the small air flow control plate 43 .
  • a part of the large air flow control plate 41 is a bearing 44 that receives an output shaft for the up-down deflector 8 b and the up-down deflector driving motor 24 b .
  • the strength of the bearing 44 can be increased by forming the large air flow control plate 41 so that the part of the plate is the bearing 44 .
  • the large air flow control plate 41 in this form can be made with a smaller amount of resin used than that in a case where the large air flow control plate 41 is formed as a member separate from the bearing 44 .
  • the air outlet 23 includes an upper air flow control plate 42 , serving as an air flow control member, disposed on an upper surface of the air outlet 23 .
  • the upper air flow control plate 42 is disposed between the infrared sensor 35 and the end of the left-right deflector 7 b close to the infrared sensor 35 .
  • the upper air flow control plate 42 extends downwardly from the upper surface of the air outlet 23 so that the surfaces of the plate face in the left-right direction of the air outlet 23 .
  • the left-right deflector driving motor 25 b and a drain port (not illustrated) for connection to a drain hose for discharging water generated during cooling to an outdoor space are arranged.
  • a drain port (not illustrated) for connection to a drain hose for discharging water generated during cooling to an outdoor space.
  • There is no side wall close to the pseudo air passage 45 through which conditioned air is not blown.
  • an air flow can be sent farther to the right than that in a case where an air passage side wall is placed close to the pseudo air passage 45 .
  • the conditioned air flowing toward the infrared sensor 35 through the small air flow control plate 43 , the upper air flow control plate 42 , and the large air flow control plate 41 in that order experiences higher flow resistance, as the conditioned air approaches the infrared sensor 35 while passing through a zigzag path defined by these three plates extending in the up-down direction. Consequently, the conditioned air is gradually deflected to the front side, and is completely deflected to the front side by the large air flow control plate 41 .
  • conditioned air blown from the air outlet 23 would contact the casing 36 covering the infrared sensor 35 .
  • the temperature in the casing 36 would vary with fluctuations of the conditioned air blown from the air outlet 23 .
  • the temperature in the casing 36 would disturb the amount of infrared radiation to be detected by the infrared sensor 35 , resulting in an incorrect amount of infrared radiation.
  • the infrared sensor 35 could not correctly obtain information about the temperature of a floor, the temperature of a wall surface, the position of a human body, and an activity condition of the human body.
  • FIG. 11 is an enlarged view illustrating air flows in the vicinity of the infrared sensor 35 in the horizontal blowing operation mode of an air-conditioning-apparatus indoor unit 1 according to Embodiment 2 of the present invention.
