  • the attachment/detachment detecting sensor 30 is a push button switch, and the arm member 32 is disposed which faces the push button 31 of the attachment/detachment detecting sensor 30, such that, when the wind direction plate unit 10 is attached, the projection 15 slides on the arm member 32 to press the push button 31.
  • the push button 31 securely pressed on attaching the wind direction plate unit 10 to the housing 2, even in a case where the stroke (moving distance) of the push button 31 is short.
  • FIG. 15 shows a perspective view of an air conditioner of the second embodiment.
  • the second embodiment is different from the first embodiment in that the second embodiment includes an occupancy sensor 40. In the other respects, the second embodiment is similar to the first embodiment.
  • an occupancy sensor 40 which detects a human body existing in a room, to point in a lower frontward direction with respect to the housing 2.
  • the occupancy sensor 40 is an infrared sensor, and detects a human body existing in the room.
  • the occupancy sensor 40 has a predetermined view angle (for example, 60°) in the left-right direction.
  • FIG. 16 and FIG. 17 show a perspective view and a side sectional view, respectively, of the occupancy sensor 40.
  • the occupancy sensor 40 is disposed inside an opening 40a of the housing 2. Over the opening 40a, there is disposed an accommodation chamber 40c which has an opening 40b in a front face thereof, and an operation lever 41 is disposed in the accommodation chamber 40c.
  • the operation lever 41 is coupled to the occupancy sensor 40 via a rotation shaft 41a disposed at a rear end of the operation lever 41.
  • the operation lever 41 and the occupancy sensor 40 are both rotatable about the rotation shaft 41a in the left-right direction.
  • a recess 41a is formed, and in a front part of the operation lever 41, a convex part 41b is disposed behind the recess 41a to project upward in a hemispherical shape. As illustrated in FIG.
  • a plurality (three, in the present embodiment) of concave parts 40d are aligned in the left-right direction, in each of which the convex part 41b is fittable.
  • a lid 42 which is made of resin, openable and closable, and covers the operation lever 41.
  • a lower end of the lid 42 is pivotally supported on the housing 2 via a horizontal shaft, and on a back of an upper end part of the lid 42, a projection 42a is disposed to project rearward to fit in the recess 41a of the operation lever 41.
  • the lid 42 has an engagement claw 42b disposed at each side end part of the lid 42 to engage in one of engagement holes 42c of the housing 2, and, at an upper end of the lid 42, a handle 42d is disposed.
  • a step part 40g is disposed, with a predetermined gap between the handle 42d and the step part 40g when the lid 42 is in a closed state. With this configuration, it is possible to easily hold the handle 42d of the lid 42 in the close state.
  • the lid 42 has an opening 42f formed at a position opposing the occupancy sensor 40.
  • a person who installs the air conditioner 1 holds the handle 42d and opens the lid 42. At this time, the engagement claw 42b is elastically deformed such that the engagement thereof with the engagement hole 42c is released.
  • the operation lever 41 is rotated about the rotation shaft 41a in the left-right direction to fit the convex part 41b in a left one of the concave parts 40d. As a result, as illustrated in FIG. 19 , the operation lever 41 is inclined leftward such that a left side surface of the operation lever 41 contacts a left side surface of the accommodation chamber 40c. And, when the lid 42 is closed, a right side surface of the operation lever 41 is caught by the projection 42a, such that the occupancy sensor 40 is held pointing in a leftward direction as illustrated in FIG. 22 .
  • the operation lever 41 is rotated to fit the convex part 41b in a middle one of the concave parts 40d. And, when the lid 42 is closed, as illustrated in FIG. 20 , the projection 42a of the lid 42 fits in the recess 41a of the operation lever 41, such that the occupancy sensor 40 is held pointing in a frontward direction as illustrated in FIG. 23 .
  • the operation lever 41 is rotated to fit the convex part 41b in a right one of the concave parts 40d.
  • the operation lever 41 is inclined rightward such that the right side surface of the operation lever 41 contacts a right side surface of the accommodation chamber 40c.
  • the lid 42 is closed, the left side surface of the operation lever 41 is caught by the projection 42a, such that the occupancy sensor 40 is held pointing in a rightward direction as illustrated in FIG. 24 .
  • the pointing operation of the occupancy sensor 40 is changeable in the left-right direction by operating the operation lever 41. This makes it possible to optimize the detection range of the occupancy sensor 40 in accordance with the installation position of the air conditioner 1 to allow secure detection of a human body existing in the room.
  • the person who installs the air conditioner 1 does not need to touch the occupancy sensor 40 to change its direction. This helps protect the occupancy sensor 40 from being touched with a finger to be soiled.
  • the wind direction plates 12 of the wind direction plate unit 10 rotates in the left-right direction such that air is discharged through the outlet 5 avoiding the detected human body. Thereby, it is possible to prevent the user from continuously receiving wind directly from the air conditioner 1, and this helps reduce damage to the user's health.
  • the air conditioner 1 further includes the occupancy sensor 40 which detects a human body existing in the room, and discharges air through the outlet 5, avoiding the human body by means of the wind direction plates 12 of the wind direction plate unit 10. Thereby, it is possible to prevent wind from continuously blowing directly to the user, and thus to reduce damage to his or her health.
  • the air conditioner 1 further includes the operation lever 41, which is coupled to the occupancy sensor 40, and makes it possible to change the direction of the occupancy sensor 40 in the left-right direction. This allows a person who installs the air conditioner 1 to change the direction of the occupancy sensor 40 without touching the occupancy sensor 40. Thus, it is possible to reduce soiling of the occupancy sensor 40 caused by being touched with a finger. Further, since the operation lever 41 is covered by the lid 42, the direction of the occupancy sensor 40 is prevented from being unintendedly changed by, for example, the person who installs the air conditioner 1, the user, or the like.
  • the direction of the occupancy sensor 40 is variable between three directions by selectively holding one of the following three states: a state where the operation lever 41 is inclined leftward, with the right side surface thereof caught by the projection 42a (first state); a state where the projection 42a fits in the recess 41a of the operation lever 41 (second state); and a state where the operation lever 41 is inclined rightward, with the left side surface thereof caught by the projection 42a (third state).
  • FIG. 25 shows a top view of a wind direction plate unit 10 of an air conditioner 1 of the third embodiment.
  • a base part 11 of the wind direction plate unit 10 has a configuration different from its counterpart in the first embodiment.
  • the third embodiment is similar to the first embodiment.
  • a plurality of projections 11b are arranged parallel to each other at predetermined intervals in a front-rear direction.
  • the position of the press member 19 coincides with the position of the projections 11b in the left-right direction.
  • the projections 11b project upward from a flat surface 11c of the base part 11 such that a height (an amount of projection from the flat surface 11c) of each projection 11b is approximately 0.5 mm.
  • the projections 11b and the flat surface 11c between adjacent ones of the projections 11b together form an uneven 11d.
  • the uneven part 11d functions as an anti-slip surface when the user holds the wind direction plate unit 10 with his or her fingers at the position of the press member 19 in the up-down direction, and allows the user to securely hold the wind direction plate unit 10 while pressing the press member 19 upward. This further improves the user-friendliness of the air conditioner 1.
  • the projections 11b do not become a large resistance to air flowing in the air passage 6, and thus does not very much hinder the blowing performance of the air conditioner 1.
  • the uneven part 11d is disposed on the outer surface of the base part 11 such that the position of the press member 19 and that of the uneven part 11d coincide with each other in the left-right direction. Thereby, it is possible for the user to securely hold the wind direction plate unit 10 in detaching the wind direction plate unit 10.
  • an uneven part may be formed by arranging dotted projections, instead of the linear projections 11b, in a matrix pattern on the outer surface of the base part 11.
  • an uneven part similar to the uneven part 11d of the present embodiment may be disposed in the air conditioner 1 of the second embodiment.
  • the present invention is applicable to air conditioners having a wind direction plate which changes the direction of air discharged through an outlet in the left-right direction.
