By sliding the operation knob 45 to the left and right with respect to the horizontal louver 42, the vertical louver 41 is moved. By rotating, the direction of the air blown out from the inner flow path 15a can be adjusted in the left-right direction.

  As shown in FIGS. 1, 3, and 5, the register device 1 further includes a flow path selection mechanism 50. The flow path selection mechanism 50 selects a flow path of air flowing in the downstream portion of the ventilation path 15, and includes a pair of upper and lower control plates 51, 51 (opening / closing means) and one side wall 13 of the apparatus body 10. The operation dial 52 (operation member) rotatably supported on the outer surface of the control dial 52, and a link mechanism 53 that links the operation dial 52 and the pair of control plates 51, 51 are provided.

As shown in FIGS. 6 and 7, the pair of control plates 51, 51 are arranged in the middle of the ventilation path 15 and upstream of the inner case 20. The base end portions of the control plates 51 and 51 are rotatably supported by the left and right side walls 13 in the vicinity of the step portions 11a and 12a of the upper wall 11 and the lower wall 12 and downstream thereof.
A part of the operation dial 52 protrudes indoors from an operation hole 33 formed in the cover 30.

  The link mechanism 53 has first to third links 54, 55, and 56. The first ring 51 has a linear shape, and its rear end is rotatably connected to the operation dial 52. The second link 56 has a cross shape, and then the arm portion is rotatably connected to the front end portion of the first link 51, and the forearm portion slides back and forth on the guide 19 formed on one side wall 13 of the apparatus body 10. Supported as possible.

  As shown in FIG. 3, one end portion of the pair of third links 56, 56 has rotation shaft portions 56 a, 56 a, and the rotation shaft portions 56 a, 56 a are inserted into support holes 13 a formed in the side wall 13. Thus, the side wall 13 is rotatably supported. The base end portions of the control plates 51 and 51 are connected to the rotation shaft portions 56a and 56a so as not to be relatively rotatable.

  As shown in FIG. 3, a slide pin 56 b is fixed to the other end portion of the third link 56, and the slide pin 56 b is vertically formed on the upper arm portion and the lower arm portion of the second link 55. By inserting the slit 55a extending in the direction, the other end of the third link 56 is connected to the second link 55 so as to be slidable and rotatable in the vertical direction.

  When the operation dial 52 is turned, the second link 55 is moved in the front-rear direction via the first link 54, and the control plates 51, 51 are rotated via the third links 56, 56 accordingly. Yes. The control plates 51 and 51 are moved to the positions shown in FIG. 7A, the positions shown in FIGS. 6A and 7B, and the positions shown in FIGS. The rotation is continuously adjusted so that the positions shown in (C) can be sequentially selected.

  The operation of the register device having the above configuration will be described. 1 and 5 show a state in which the flow path selection mechanism 50 has the control plates 51 and 51 at the position shown in FIG. When the control plates 51 and 51 are at the position shown in FIG. 7A, their tips are in contact with each other. Further, the steps 11 a and 12 a between the upper wall 11 and the lower wall 12 of the apparatus main body 10 have a circular arc shape corresponding to the rotation trajectory of the base end portions of the control plates 51 and 51. The base end portion of the is approaching the steps 11a and 12a. As a result, the control plates 51 and 51 can block (fully close) the air flow from the ventilation path 15. Therefore, for example, among the register devices 1 arranged in the driver's seat and the passenger seat, the air from one register device 1 can be stopped while the air from the other register device 1 can be stopped.

  When the operation dial 52 is turned counterclockwise in FIG. 5 from the air blow stop state, the first and second links 54 and 55 are moved rearward, and the third link 56 is rotated rearward. Along with this, the control plates 51 and 51 rotate in the direction of the arrow in FIG. 7A, and the leading edge thereof rotates toward the inner case 20.

As shown in FIGS. 6A and 7B, the front ends of the control plates 51 and 51 reach the vicinity of the upstream edge of the upper wall 21 and the lower wall 22 of the inner case 20. As a result, the control plates 51 and 51 close the upstream ends of the upper and lower flow path portions of the peripheral flow path 15b. As shown in FIGS. 8 and 9, the upstream ends of the left and right flow channel portions of the peripheral flow channel 15 b are always closed by shielding convex portions 29 and 29. As a result, the shielding projections 29 and 29 and the control plates 51 and 51 cooperate to close the peripheral flow path 15b over the entire circumference. As a result, the air flowing in from the inlet 15x of the ventilation path 15 flows into the inner flow path 15a, passes through the inner flow path 15a, and is concentrated and blown out in a relatively narrow angle range.
At this time, the direction of the concentrated air can be adjusted by adjusting the wind direction adjusting mechanism 40.

  When the operation dial 52 is further turned counterclockwise, the control plates 51 and 51 are separated from the upper wall 21 and the lower wall 22 of the inner case 20 as shown in FIGS. 6B and 7C, respectively. It approaches the upper wall 11 and the lower wall 12 of the main body 10 and is substantially parallel to the upper wall 11 and the lower wall 12. As a result, the upstream ends of the upper channel portion and the lower channel portion of the peripheral channel 15b are opened, so that the air that has entered from the introduction port 15x is not only the inner channel 15a but also the upper channel of the peripheral channel 15 It flows through the part and the lower flow path part. Furthermore, part of the air that has flowed into the upper flow path portion and the lower flow path portion bypasses the shielding convex portion 29 and circulates downstream thereof, so that it also flows to the left and right flow path portions of the peripheral flow path 15. Therefore, air blows out from the entire circumference of the peripheral flow path 15b at the outlet 15y. As described above, when the control plates 51 and 51 are at the positions shown in FIGS. 6B and 7C, air blows not only from the inner flow path 15a but also from the entire circumference of the peripheral flow path 15b. Air blowing is performed (diffusion air blowing). Therefore, the occupant receives a gentle air flow and can improve comfort.

  At the time of the diffused air, the upper wall 21 and the lower wall 22 of the inner case 20 are inclined so as to be separated from each other in the vertical direction, so that they are blown out from the upper channel portion and the lower channel portion of the peripheral channel 15b. The air that spreads further spreads up and down. In addition, the air passing through the upper flow path portion and the lower flow path portion of the peripheral flow path 15b is spread left and right by the guide ribs 25 to 28 and blown out. Furthermore, the air that flows around the shielding convex portion 29 and flows through the left and right flow path portions of the peripheral flow path 15b spreads left and right by the left and right side walls 23 that are inclined in directions away from each other. As a result, the diffused air can be favorably performed.

  In the inner flow path 15a, the flow cross-sectional area increases toward the blowout port 15y, whereas in the peripheral flow path 15b, the flow cross-sectional area decreases toward the blowout port 15y. On the other hand, the air is blown out from the peripheral flow path 15b at a relatively high flow rate. Also by this, the diffused air can be favorably performed.

  The direction of the air blown out from the inner flow path 15a can be adjusted by the wind direction adjusting mechanism 40 also during the diffusion air blowing.

The present invention is not limited to the above-described embodiment, and various aspects can be made.
For example, the flow path selection mechanism may be omitted. The second air blowing guide may be omitted.
In the above embodiment, the left and right side walls of the inner case may be used as the second air guide. In this case, if the inclination of the side wall is made larger than that in the above embodiment, the diffusion effect in the left-right direction can be enhanced.
The left and right side walls of the inner case may be used as first air guides, and guide ribs that are inclined in the vertical direction may be provided on these side walls as second air guides.
The cross section of the peripheral wall of the apparatus main body and the inner case may be circular. In this case, the upper part and the lower part of the peripheral wall of the inner case may be provided as one of the first and second air blowing guides, and the left and right parts may be provided as the other.

  The present invention can be applied to a register device for air conditioning of a vehicle.
