  The present invention relates to a wind direction changing device including a plurality of vertical wind direction plates provided at an air outlet and an air conditioning device including the same.

  2. Description of the Related Art Conventionally, a wind direction changing device for changing a wind direction to the left or right is installed at an air outlet of an indoor unit or the like of an air conditioner. As shown in FIG. 9, the wind direction changing device includes a plurality of vertical wind direction plates 36 that are rotatable about a rotation axis that is substantially orthogonal to the left and right lateral direction 35 of the air outlet 34.

  The vertical wind direction plate 36 is divided into a right side wind direction plate group 37 located in the right half of the air outlet 34 and a left side wind direction plate group 38 located in the left half of the air outlet 34. The wind direction can be adjusted independently according to the shape of the indoor space.

The wind direction plate groups 37 and 38 include an interlocking rod 39 that rotates the vertical wind direction plate 36 in an interlocked manner, and further includes a drive motor 40 for rotating the vertical wind direction plate 36. From the viewpoint of structure and workability, the drive motor 40 is configured such that the motor shaft is directly connected to the rotary shaft of the vertical wind direction plate 36 closest to the end of the air outlet in the wind direction plate groups 37 and 38, respectively.

As such a wind direction changing device that controls the rotation of the vertical wind direction plates of the left and right wind direction plate groups using the two drive motors, for example, the one described in Patent Document 1 is known.
Japanese Patent Laid-Open No. 9-4916

  However, in the said wind direction change apparatus, since the position of the two drive motors 40 is separated, the wiring distance of the motor becomes long, wiring work becomes complicated, and the manufacturing cost increases.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a wind direction changing device capable of suppressing the manufacturing cost without complicating the wiring work and an air conditioning device including the same. .

  In order to solve the above-described problems, in the present invention, in the air outlet formed in the casing, a plurality of rotations about a rotation axis substantially orthogonal to the left and right lateral direction of the air outlet and the plate surface direction as the vertical direction are possible. It is a wind direction changing device in which vertical wind direction plates are arranged in a louver shape in the lateral direction at intervals, and the vertical wind direction plates are divided into wind direction plate groups that divide the air outlet into a plurality of wind direction plate groups. A wind direction variable means for rotating the vertical wind direction plate in conjunction with the drive motor is provided, and each drive motor is installed at a close position.

  According to the above configuration, since the drive motors are installed at positions close to each other, the wiring work from the power source to the drive motor can be performed collectively, and the manufacturing cost can be suppressed without complicating the wiring work. Can be obtained.

  The vertical wind direction plate can be divided into a plurality of arbitrary wind direction plate groups, but the right wind direction plate group located in the right half of the air outlet and the left wind direction plate group located in the left half of the air outlet. If it divides into a group, a wind direction can be changed arbitrarily, suppressing manufacturing cost.

  If each drive motor is installed in the position which adjoins in either the right or left edge part of an air blower outlet, it can suppress that it becomes an obstruction | occlusion of an air blowing.

  As a wind direction change means, it can be set as the structure provided with the connection pin formed in the position eccentric from the rotation center in the vertical wind direction board, and the interlocking rod which connects the connection pin of each vertical wind direction board rotatably.

  For specific drive motor arrangement, the drive motor of one wind direction plate group is directly connected to the rotation axis of the vertical wind direction plate closest to the end of the air outlet, and the drive motors of the other wind direction plate groups are Installed at a position close to the drive motor of the other wind direction plate group and connected to the rotation axis of the vertical wind direction plate closest to the installation position of the drive motor among the other wind direction plate groups via a link mechanism be able to.

  According to this configuration, since the drive motor of one wind direction plate group is directly connected to the rotation shaft of the vertical wind direction plate, the number of link mechanisms can be reduced correspondingly, and the structure of the wind direction changing device is prevented from becoming complicated. can do. The arrangement of the drive motor is not limited to the above-described configuration. For example, for both wind direction plate groups, the drive motor can of course be connected to the rotary shaft of the vertical wind direction plate via a link mechanism. .

  As the link mechanism, the wind direction plate arm portion protruding in the radial direction from the rotation axis of the vertical wind direction plate, the motor arm portion protruding in the radial direction from the rotation shaft of the drive motor, and the tips of both arm portions are connected to each other. It can be composed of a connecting rod that is rotatably connected, and by making the lengths of both arms the same, the rotation angle of the drive motor and the rotation angle of the vertical arm connected by the link mechanism can be made the same. Can do.

  In the above link mechanism, if the connecting rod is made of a synthetic resin, it is possible to drive the left and right wind direction plate groups independently using a synthetic resin that is cheaper than the wiring, as in the past, thereby reducing manufacturing costs. It becomes possible to do.

  The wiring of the drive motor starts from an electrical component housing section that houses electrical components on which electrical components are mounted. This electrical component housing portion is installed on one side surface of the casing while avoiding the air outlet due to space problems. Therefore, if the drive motor is installed at the end of the air outlet near the electrical component housing portion, the wiring from the electrical component housing portion to the drive motor can be shortened, and the manufacturing cost can be further suppressed. Become.

  In addition to the vertical wind direction plate, the wind direction changing device can also be provided with a horizontal wind direction plate that is pivotally supported so that the rotation axis direction is parallel to the horizontal direction of the air outlet.

  The wind direction changing device of the present invention can be mounted on various air conditioners such as an air conditioner, an air purifier, a dehumidifier, a humidifier, an electric heater, a petroleum stove, a gas heater, and a refrigerator.

  As described above, according to the present invention, the vertical wind direction plate is divided into the wind direction plate groups that divide the air outlet into a plurality of air direction outlets, and the wind direction variable that rotates the vertical wind direction plate in conjunction with the drive motor for each wind direction plate group. Since the means is provided and the drive motors are installed at positions close to each other, the manufacturing cost can be suppressed without complicating the wiring work.
