  By the way, the interlocking device of the wind direction adjusting mechanism has a case where the interlocking rod is connected to a driving source and a case where the interlocking rod is manually operated. In the case where the interlocking rod is connected to the drive source and the case where it is manually operated, it is necessary to change the contact pressure when the coupling pin and the coupling hole are fitted.

  For example, in the case of manual operation, increase the rotational torque of the vertical wind direction plate to restrict the vertical wind direction plate from rotating relatively easily due to vibration, etc. The degree of fitting between the connecting pin and the connecting hole is adjusted so that the vertical wind direction plate rotates with a relatively small torque.

  The vertical wind direction plate and the interlocking rod are assembled and the torque is adjusted by changing the dimensions of the connecting pin or the connecting hole. As shown in FIG. 7, the connecting hole 100 of the interlocking rod is aligned with the connecting pin. Since the slit 102 is formed in the connecting hole portion 101 having a round hole shape, there is a variation in assembly or torque adjustment due to a change in temperature or a variation in molding or assembly, and there is a problem in quality stability.

  In view of the above, the present invention provides an interlocking device for a wind direction adjusting mechanism that can easily adjust dimensions and torque, and that can improve torque management and assembling performance against deformation due to variations in temperature, molding, and assembly. It is an object.

  In order to achieve the above object, according to the present invention, a plurality of vertical wind direction plates, which are rotatable around the vertical axis and have the plate surface direction as the vertical direction, are spaced apart from each other in the horizontal direction at the outlet for blowing out air. In the wind direction adjusting mechanism arranged in a louver shape, an interlocking rod for rotating the plurality of vertical wind direction plates in an interlocking manner is provided, and each vertical wind direction plate is provided in a plurality of connecting holes formed at intervals in the interlocking rods. The connecting pin with the head is inserted and the connecting pin is rotatably connected to the interlocking rod, and a plurality of protrusions that are pointed to the connecting pin are formed at intervals in the hole wall of the connecting hole. Features.

  According to the above configuration, since the plurality of protrusions that make contact with the connecting pin are formed at intervals on the hole wall of the connecting hole, it is easy to adjust the dimensions and torque, and against deformation due to temperature changes and variations. Torque management and assembly can be improved.

  In addition to the above configuration, the protrusion amount of the protrusion is set to be different between when the interlocking rod is connected to the drive source and when the interlocking rod is manually operated. Thereby, it is possible to provide an interlocking kit that matches the connection target, and it is possible to deal with both modes only by changing the interlocking kite.

  Moreover, the some rib which contacts the edge of the vertical wind direction board of a connection pin and / or the head of a connection pin can be formed in the thickness direction of an interlocking rod.

  According to the said structure, several ribs can be provided similarly with respect to the thickness direction of an interlocking rod, and the shading in the axial direction of a connection pin can be adjusted.

  The air outlet is an air outlet of an air conditioner such as an air conditioner, a humidifier, a dehumidifier, an air purifier, or a heater. In these air conditioners, the present invention is applied to an air outlet of an indoor unit. Is preferred.

  As described above, according to the present invention, a plurality of protrusions are formed at intervals on the hole wall of the connection hole, so that the connection pin and the point of contact are contacted, and the adjustment of dimensions and torque can be easily performed. Torque controllability and assemblability against deformation due to temperature changes and variations can also be improved.

The side view which shows the state before a connection with an interlocking hook, (b) is a side view which shows the connection state of a vertical wind direction board and an interlocking hook. 4 is an enlarged plan view of a connecting hole portion of the interlocking rod, FIG. 5 is a cross-sectional view taken along line AA in FIG. 4, and FIG. 6 is a cross-sectional view taken along line BB in FIG.

  As shown in the figure, a wind direction adjusting mechanism 1 according to the present invention is a plurality of vertical wind direction plates 4 that are rotatable around a vertical axis 3 and have a plate surface direction as a vertical direction at an outlet 2 for blowing out air. Are arranged in a louver shape in the lateral direction at intervals. Although not shown, a horizontal wind direction plate is usually disposed in front of the vertical wind direction plate 4 so that the wind direction can be controlled in the vertical direction.

  As shown in FIG. 3, each vertical wind direction plate 4 includes a blade portion 4a having a plate surface direction as a vertical direction, a shaft portion 4c with a flange 4b formed at the rear end portion of the blade portion, and a blade portion 4a. The connecting pin 9 of the interlocking device 5 that protrudes downward from the lower end edge of the blade portion 4a at an intermediate position in the front-rear direction is integrally formed of synthetic resin.

  As shown in FIG. 1, the shaft portion 4 c is rotatably connected to a shaft hole (not shown) formed in the mouth wall 2 a that forms the air outlet 2. Further, the shaft flange 4b of the vertical wind direction plate 4 located at both left and right ends of the air outlet 2 is partially cut out at the periphery thereof, and a stopper pin protruding from the mouth wall 2a side of the air outlet 2 at the notch 4d. 2b is engaged and the rotation range of the vertical wind direction plate 4 is regulated. Since the range of rotation of the vertical wind direction plates 4 at the left and right ends is restricted and the other vertical wind direction plates 4 are connected by the interlocking rod 6 of the interlocking device 5, the rotation range of all the vertical wind direction plates 4 is Will be regulated.

  In the present embodiment, an interlocking device 5 that rotates these vertical wind direction plates 4 in conjunction with each other is provided. The interlocking device 5 includes an interlocking rod 6 that rotates a plurality of vertical wind direction plates 4 in an interlocking manner. In the present embodiment, a pair of left and right interlocking rods 6 are arranged so that the vertical wind direction plates 4 are interlockedly connected to each other at the left half and the right half of the air outlet 2.

  And the connection pin 9 with the head 8 of each vertical wind direction board 4 is inserted in the connection hole 7 formed in the interlocking rod 6 at intervals in the direction of the flange, and the connection pin 9 is connected to the interlocking rod 6. Is pivotally connected to the motor.

  As shown in FIG. 3, the connecting pin 9 has a cylindrical pin portion 9 a and a head portion 8 having a lower diameter formed at the lower end thereof than the pin portion.

  On the other hand, as shown in FIGS. 2 and 4, the connecting hole 7 includes a circular connecting hole portion 7 a and a hole wall in the heel direction in the thick bearing portion 6 a formed at intervals in the interlocking rod 6. And a pair of left and right slits 12 formed along. The slit 12 is formed to facilitate the insertion of the head 8 of the connecting pin 9 into the connecting hole 7a.

  In addition, a plurality of protrusions 10 that hit points with the pin portion 9a of the connecting pin 9 are formed at intervals along the hole wall of the connecting hole portion 7a. The protrusion amount of the protrusion 10 is set to be different between when the interlocking rod 6 is connected to the drive source and when the interlocking rod 6 is manually operated. For example, in the case of manual operation, in order to restrict the vertical wind direction plate from rotating relatively easily due to vibration or the like by increasing the rotational torque of the vertical wind direction plate 4, the protrusion amount of the protrusion 10 is transferred to a drive source such as a motor. It is larger than when connecting. Further, when the interlocking rod 6 is connected to a drive source such as a motor, the projection amount of the projection 10 is made smaller than that in the case of manual operation so that the vertical wind direction plate 4 rotates with a relatively small torque, and the connecting pin 9 And the coupling hole 7 are adjusted.

  Further, as shown in FIG. 4, one or both surfaces of the interlocking rod 6 are in contact with the lower end edge of the vertical wind direction plate 4 of the connecting pin 9 and / or the head 8 of the connecting pin 9 around the connecting hole 7. A plurality of ribs 11 are formed in the thickness direction, and the lower end edge of the vertical wind direction plate 4 and / or the head portion 8 abuts on the ribs 11 so that the variation in the thickness direction of the interlocking rod 6 can be adjusted. . The ribs 11 are formed radially around the connecting hole 9a. In the present embodiment, ribs 11 are formed along a total of six protrusions 10.

  In addition, you may form the rib 11 only in the single side | surface other than forming in the front and back both surfaces of the interlocking rod 6. FIG. Further, as shown in FIGS. 2 and 6, the interlocking rod 6 has reinforcing ribs 13 formed at intermediate positions between the connecting holes 7.

  In the wind direction adjusting mechanism having the above-described configuration, the interlocking device 5 is assembled to deflect the vertical wind direction plate 4 in an interlocking manner. The interlock device 5 is assembled by inserting the connecting pin 9 of the vertical wind direction plate 4 into the connecting hole 7 of the interlocking rod 6. At this time, since the slits 12 are formed on the left and right sides of the connecting hole 7, even if the head 8 of the connecting pin 9 is smaller in diameter than the diameter of the connecting hole 7, the deformation of the slit 12 causes the deformation of the connecting pin 9. The head portion 8 penetrates the connecting hole 7 and the pin portion 9a of the connecting pin 9 is easily inserted into the connecting hole portion 7a.

  In a state where the connecting pin 9 is inserted into the connecting hole 7, the protrusion 10 formed on the hole wall of the connecting hole 7 a and the pin portion 9 a of the connecting pin 9 will hit each other. Therefore, adjustment of dimensions and torque is facilitated, and torque management and assembling performance against deformation due to temperature change and variation can be improved.

  In addition, the interlocking rod 6 is prepared so that the protrusion amount of the protrusion 10 is different between the case where the interlocking rod 6 is connected to a drive source such as a motor and the case where the interlocking rod 6 is manually operated. Then, the interlocking rod 6 is selected and assembled according to the connection target. If it does so, it can set to the rotational torque suitable for a drive source or manual operation, and only by changing the interlocking | linkage rod 6, others can comprise an interlocking device using a common component.

  Furthermore, since the plurality of ribs 11 that contact the lower end edge of the vertical wind direction plate 4 of the connecting pin 9 and / or the head 8 of the connecting pin 9 are formed in the thickness direction of the interlocking rod 6, the thickness direction of the interlocking rod 6 In the same manner, that is, the shading in the axial direction of the connecting pin 9 can be adjusted.

  In the present embodiment, the present invention is applied to the interlocking device of the wind direction adjusting mechanism at the outlet of the indoor unit of the air conditioner. However, the present invention is not limited to this, and a humidifier, a dehumidifier, an air cleaner, a heater, etc. Of course, the present invention may be applied to the air outlet of other air conditioners.
