Definitions

  • the present invention relates to air conditioners and methods for adjusting the sensor direction of air conditioners.
  • a human-detecting sensor may be provided on an indoor unit of an air conditioner to adjust the operation of the air conditioner, for example, the air volume or direction thereof, depending on the presence, position, etc. of a person in the room. If the detection direction of the human-detecting sensor cannot be changed because it is fixed to the indoor unit, it may have a large blind spot, depending on the installation position of the indoor unit. Thus, the detection direction of the human-detecting sensor needs to be changed.
  • PTL (Patent Literature) 1 discloses an invention related to air conditioners, specifically, a technique for allowing the user to clearly ascertain the direction of a sensor part by providing a transparent or translucent grid-like cover on a front panel at a front position corresponds to a radiation sensor so as to be attachable to and detachable from the front panel.
  • PTL 2 discloses an invention related to infrared sensors, specifically, a technique for allowing the detection direction of a sensor part to be changed by configuring the sensor part so as to be rotatable.
  • the detection direction of a human-detecting sensor can be changed by changing the sensor direction using a motor or manually by the user.
  • the use of a motor involves structural complexity and requires a large space for installation of the motor. If the sensor direction is manually changed by the user, on the other hand, the structure where the user manually changes the sensor direction needs to be shaped to allow the user to easily put his or her hand therein and to easily change the direction, which often requires a large space. In addition, the sensor, which is structurally vulnerable, is likely to be touched by the user.
  • an object of the present invention is to provide an air conditioner and a method for adjusting the sensor direction of an air conditioner that allow the detection direction of a sensor part to be easily changed with a simple structure.
  • an air conditioner and a method for adjusting the sensor direction of an air conditioner according to the present invention employ the following solutions.
  • an air conditioner according to a first aspect of the present invention includes a sensor part that is disposed in a main body of an indoor unit and that is rotatable in a direction in which a detection range thereof is changed, a mounting part that is formed on an axis of a rotating shaft of the sensor part and that rotates together with the sensor part, and a cover part that is attachable to and detachable from the main body of the indoor unit and that surrounds the mounting part when attached to the main body of the indoor unit.
  • the cover part includes a holding portion that is attachable to the mounting part so as to rotate the mounting part about an axis thereof and a lever portion disposed on the holding portion so as to extend in one direction.
  • the sensor part disposed in the main body of the indoor unit is rotatable and is rotated to change the detection range of the sensor part.
  • the mounting part is formed on the axis of the rotating shaft of the sensor part, and the sensor part rotates together with the mounting part when the mounting part rotates.
  • the cover part is attachable to and detachable from the main body of the indoor unit and is attached to the main body of the indoor unit so as to surround the mounting part.
  • the holding portion of the cover part is attachable to the mounting part, and the lever portion is disposed on the holding portion so as to extend in one direction. After the holding portion is attached to the mounting part, the lever portion can be manipulated to rotate the holding portion, the mounting part, and the sensor part about the axis of the rotating shaft of the sensor part.
  • the mounting part may be disposed inside an opening provided in the indoor unit such that an end of the mounting part is positioned deeper inside the main body of the indoor unit than an opening surface where the opening is provided, and the holding portion may be inserted into the opening and be attached to the mounting part.
  • the mounting part is attached inside the opening provided in the indoor unit, and the holding portion of the cover part is inserted into the opening and is attached to the mounting part.
  • the holding portion can be attached to the mounting part even though the top end of the mounting part is positioned deeper inside the main body of the indoor unit than the opening surface where the opening is provided.
  • the mounting part and the sensor part can be positioned deeper in the indoor unit so that the mounting part and the sensor part are unlikely to be touched by the user of the indoor unit, which contributes to protection of the sensor part.
  • a method for adjusting a sensor direction of an air conditioner is a method for adjusting a sensor direction of an air conditioner including a sensor part that is disposed in a main body of an indoor unit and that is rotatable in a direction in which a detection range thereof is changed, a mounting part that is formed on an axis of a rotating shaft of the sensor part and that rotates together with the sensor part, and a cover part that is attachable to and detachable from the main body of the indoor unit and that surrounds the mounting part when attached to the main body of the indoor unit.
  • the method includes a step of attaching a holding portion of the cover part to the mounting part and a step of rotating a lever portion disposed on the holding portion of the cover part so as to extend in one direction to rotate the mounting part and the sensor part about an axis thereof.
  • the lever portion can be manipulated to rotate the holding portion, the mounting part, and the sensor part about the axis of the rotating shaft of the sensor part, which allows the detection direction of the sensor part to be easily changed with a simple structure.
  • FIG. 1 is a front view of the indoor unit 1 of the air conditioner.
  • the indoor unit 1 of the air conditioner includes a main body case 2 accommodating, for example, a heat exchanger through which a refrigerant flows, a fan, a motor, and a drain pan.
  • a main body case 2 accommodating, for example, a heat exchanger through which a refrigerant flows, a fan, a motor, and a drain pan.
  • the front of the main body case 2 has an inlet 3, an outlet 4, a sensor cover 5, and the cover/adjuster 6. Air taken into the inlet 3 is directed through the fan to the heat exchanger. The air cooled or heated through the heat exchanger is fed from the outlet into the room.
  • the sensor cover 5 is disposed on the room side of the human-detecting sensor 9.
  • the sensor cover 5 prevents the human-detecting sensor 9 from being contaminated or damaged by an external influence such as being touched by the user's hand.
  • the human-detecting sensor 9 is supported by and fixed to a shaft 10 and is rotatable about the axis of the shaft 10.
  • the human-detecting sensor 9 is accommodated in a sensor case 8, and the shaft 10 is supported by the sensor case 8.
  • the sensor case 8 is open on the room side thereof and is fixed to the main body case 2.
  • the shaft 10 is mounted on the sensor case 8 so that the direction of the human-detecting sensor 9 can be changed, for example, in the side-to-side direction as viewed from the front of the indoor unit 1.
  • the shaft 10 is tilted with respect to the vertical direction so that the range below the indoor unit 1 can be detected.
  • the detection range of the human-detecting sensor 9 can be changed by rotating the human-detecting sensor 9 about the axis of the shaft 10.
  • a mounting part 7 is formed on the axis of the rotating shaft of the human-detecting sensor 9.
  • the mounting part 7 is formed at the top end of the shaft 10.
  • the cross-section of the mounting part 7 taken along the direction perpendicular to the axial direction is hexagonal, which corresponds to the shape of a holding portion 12 of the cover/adjuster 6, described later.
  • the shaft 10 and the human-detecting sensor 9 rotate together with the mounting part 7 when the mounting part 7 rotates.
  • a groove 14 extending in one direction is formed in the top surface of the mounting part 7.
  • the groove 14 coincides with the direction along the center of the detection range of the human-detecting sensor 9. This allows the user to view the direction of the groove 14 to check the direction of the human-detecting sensor 9.
  • the mounting part 7 is disposed inside an opening 13 formed in the front of the main body case 2.
  • the top end of the mounting part 7 is positioned deeper inside the main body case 2 of the indoor unit 1 than the opening surface where the opening 13 is formed.
  • the cover/adjuster 6 is attachable to and detachable from the main body case 2 and, as shown in Fig. 4 , includes, for example, the holding portion 12 and a lever portion 11.
  • the cross-section of the inner surfaces of the holding portion 12 is hexagonal, which corresponds to the hexagonal shape of the mounting part 7, and the holding portion 12 is attachable to the mounting part 7 so as to rotate the mounting part 7 about the axis thereof.
  • the lever portion 11 is disposed on the holding portion 12 so as to extend in one direction.
  • the holding portion 12 is disposed at one end of the lever portion 11.
  • the direction in which the lever portion 11 extends i.e., the longitudinal direction, is perpendicular to the axial direction of the shaft 10 when the cover/adjuster 6 is attached to the mounting part 7.
  • the cover/adjuster 6 is attached to the opening 13 so as to surround the mounting part 7.
  • the opening 13 is normally closed, which prevents, for example, entry of foreign matter into the main body case 2.
  • the cover/adjuster 6 is detached from the opening 13 when the direction of the human-detecting sensor 9 is changed.
  • the cover/adjuster 6 can be used like a wrench to change the direction of the human-detecting sensor 9. Specifically, as shown in Figs. 5 and 6 , the user attaches the holding portion 12 of the cover/adjuster 6 to the mounting part 7 and rotates the lever portion 11, thereby rotating the mounting part 7, the shaft 10, and the human-detecting sensor 9.
  • the mounting part 7 has a surface 7a perpendicular to the direction in which the groove 14 extends
  • the holding portion 12 of the cover/adjuster 6 has a surface 12a that is one of the hexagonal inner surfaces.
  • the surface 12a of the holding portion 12 is perpendicular to the longitudinal direction of the lever portion 11.
  • the direction of the groove 14 in the top surface of the mounting part 7 coincides with the longitudinal direction of the lever portion 11.
  • the user cannot directly view the human-detecting sensor 9 because the human-detecting sensor 9 is surrounded by the sensor cover 5.
  • the user can change the direction of the human-detecting sensor 9 while checking it from the longitudinal direction of the lever portion 11 of the cover/adjuster 6 attached based on the direction of the groove 14 in the top surface of the mounting part 7.
  • the cover/adjuster 6 is attached to the opening 13 of the main body case 2 and blocks the opening 13.
  • the detached cover/adjuster 6 is used to rotate the mounting part 7.
  • the holding portion 12 of the cover/adjuster 6 is first attached to the mounting part 7. This is performed such that the direction of the groove 14 in the top surface of the mounting part 7 shown in Fig. 3 coincides with the longitudinal direction of the lever portion 11.
  • the surface 7a of the mounting part 7 shown in Fig. 3 coincides with the surface 12a of the holding portion 12 shown in Fig. 4 .
  • the central axis of the detection range of the human-detecting sensor 9 faces the front of the indoor unit 1.
  • the user manipulates the lever portion 11 to change the direction and angle of the human-detecting sensor 9 to the desired direction and angle.
  • the human-detecting sensor 9 can be directed to the right by rotating the lever portion 11 to the right, and as shown in Figs. 10 and 11 , the human-detecting sensor 9 can be directed to the left by rotating the lever portion 11 to the left.
  • the cover/adjuster 6 is detached from the mounting part 7. The detached cover/adjuster 6 is attached to the opening 13 and blocks the opening 13.
  • this embodiment allows the direction of the human-detecting sensor 9 to be easily changed using the cover/adjuster 6.
  • the user can easily manipulate the cover/adjuster 6 and the mounting part 7 because they can be handled as in the relationship between a wrench and a bolt head.
  • the cross-section of the cover/adjuster 6 taken in the longitudinal direction of the lever portion 11 is L-shaped.
  • the cover/adjuster 6 has a simple structure.
  • the cover/adjuster 6 normally, i.e., when the cover/adjuster 6 is attached to the opening 13, the cover/adjuster 6 does not occupy a large space.
  • the length of the holding portion 12 can be adjusted to position the top end of the mounting part 7 farther away from the opening surface where the opening 13 is formed. That is, the mounting part 7, the shaft 10, and the human-detecting sensor 9 can be positioned deeper inside the main body case 2. As a result, the human-detecting sensor 9, which is structurally vulnerable, is unlikely to be touched by the user, which contributes to protection of the human-detecting sensor 9. In addition, a smaller space is needed for the user to insert and manipulate the cover/adjuster 6 than to manually handle the human-detecting sensor 9.
