  • This invention is made in view of such a situation, Comprising: It aims at providing the indoor unit of the air conditioning apparatus which can position multiple louvers correctly.
  • the indoor unit of the air conditioning apparatus of this invention employs the following means. That is, the indoor unit of the air conditioner according to one aspect of the present invention is arranged with a predetermined interval in one direction, and has a plurality of louvers for changing the wind direction, and extends in one direction and each louver A pivotally attached connection member, a link member pivotally attached to the connection member, a motor for swinging the link member, and a motor bracket for fixing the motor to the main body And a stopper provided on the motor bracket and in contact with the connecting member.
  • the connecting member to which the link member is attached moves.
  • the louvers attached to the connecting member rotate and the wind direction is changed.
  • the motor bracket that fixes the motor to the main body is provided with a stopper that contacts the connecting member.
  • the connecting member abuts on the stopper, the movement is restricted and positioning of each louver is performed.
  • the stopper is provided on a member different from the motor bracket to which the motor is attached. Positioning of each louver can be performed accurately.
  • the stopper abuts against the connecting member at a position facing the connecting member.
  • the stopper abuts on the connecting member at a position facing directly to the connecting member, it is possible to suppress the shifting of the connecting member after the connecting member abuts on the stopper. This allows more accurate positioning of the louver.
  • the indoor unit of the air conditioning apparatus includes a control unit that controls the motor, and the control unit sets a position where the connecting member abuts on the stopper as a reference position.
  • each louver is accurately determined by the control unit setting the position where the stopper abuts the connecting member as the reference position. Thereby, the rotation angle of each louver can be controlled to a desired position.
  • FIG. 4A is a partial enlarged plan view of FIG. 4A.
  • the indoor unit 1 is in the form of a wall, and sucks indoor air from above and blows out air-conditioned air from the lower outlet into the room.
  • the indoor unit 1 is connected to an outdoor unit (not shown), receives supply of refrigerant compressed by the outdoor unit, and adjusts the temperature of the indoor air to a predetermined temperature by the indoor heat exchanger provided inside the indoor unit 1 Do.
  • the interior of the indoor unit 1 is shown in FIG.
  • the indoor heat exchanger 5 is attached to the base plate 3 fixed to the wall of the room.
  • an air outlet 7 provided in the width direction of the indoor unit 1 is formed below the indoor heat exchanger 5, an air outlet 7 provided in the width direction of the indoor unit 1 is formed.
  • the blower outlet 7 is provided with a plurality of louvers 9 at predetermined intervals in the width direction (one direction).
  • Each louver 9 is a plate made of resin.
  • Each louver 9 is rotatably attached to a bearing 11 provided on the main body side of the indoor unit 1.
  • Each louver 9 is provided with a mounting pin 9a (FIG. 3A), and the mounting pin 9a is rotatably mounted on the connecting member 13.
  • connection member 13 is made of resin and is in the shape of a bar extending in the width direction of the indoor unit 1.
  • the left end which is one end of the connection member is disposed to be located on the motor bracket 15 side.
  • the motor bracket 15 is fixed to the main body of the indoor unit 1 and accommodates a motor for driving the louver 9.
  • FIGS. 3A and 3B show enlarged views of the periphery of the connecting member 13 and the motor bracket 15.
  • One end of the link member 17 is rotatably attached to the left end of the connection member 13.
  • the other end of the link member 17 is attached to the motor shaft 19. Therefore, when the motor shaft 19 is rotated by the motor, the link member 17 is swung, thereby reciprocating the connecting member 13 in the substantially longitudinal direction.
  • the reciprocating angle of each louver 9 is changed by the reciprocation of the connecting member 13.
  • the rotation angle of the motor shaft 19 is sent to a control unit (not shown).
  • a stopper 16 is fixed to the motor bracket 15.
  • the stopper 16 restricts the movement of the connecting member 13 by abutting on the tip 13 a of the connecting member 13 as shown in FIGS. 4A and 4B.
  • the contact surface 13b of the tip 13a of the connecting member 13 and the contact surface 16a of the stopper 16 are in surface contact. That is, the contact surface 16 a of the stopper 16 is set to face the contact surface 13 b of the connecting member 13.
  • the control unit sets a position where the tip 13 a of the connecting member 13 abuts on the stopper 16 as a reference position. Then, based on the reference position, the rotation angle of the motor shaft 19 is controlled, and the position control of each louver 9 is performed.
  • the control unit is configured of, for example, a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), a computer readable storage medium, and the like. Then, a series of processes for realizing various functions are stored in the form of a program, for example, in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing and arithmetic processing. Thus, various functions are realized.
  • the program may be installed in advance in a ROM or other storage medium, may be provided as stored in a computer-readable storage medium, or may be distributed via a wired or wireless communication means. Etc. may be applied.
  • the computer readable storage medium is a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory or the like.
  • Positioning of the reference position of each louver 9 is performed as follows. First, the motor is driven by the command of the control unit, and the link member 17 is swung by the rotation of the motor shaft 19. The swinging of the link member 17 moves the tip 13a of the connection member 13 to the stopper 16 side, and the contact surface 13b of the connection member 13 is in surface contact with the contact surface 16a of the stopper 16. Thereby, the movement of the connection member 13 is restricted, and the control unit sets this position as a reference position. The control unit rotates the motor shaft 19 based on the reference position to control the wind direction angle of the louver 9.
  • the motor bracket 15 for fixing the motor to the main body of the indoor unit 1 is provided with a stopper 16 that abuts on the connecting member 13.
  • the connecting member 13 abuts against the stopper 16
  • the movement is restricted, and positioning of each louver 9 is performed.
  • the stopper 16 is provided on a member different from the motor bracket 15 to which the motor is attached like other members such as a casing. Positioning of each louver 9 can be performed more accurately than in the case.
  • each louver 9 is accurately determined by the control unit setting the position where the stopper 16 abuts on the connecting member 13 as the reference position. Thereby, the rotation angle of each louver 9 can be controlled to a desired position.
