Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is equipped with two types of fins, vertical and horizontal, for adjusting the left-right and up-down wind directions of the air-conditioning air blown from the air-conditioning device, In the swing louver type air conditioning outlet, the mode can be switched between an automatic variable mode that changes the wind direction automatically and periodically and a fixed mode that sets and fixes the wind direction in a desired direction by adjustment by manual operation. , The structure of the operating portion for manually adjusting the vertical and horizontal wind directions.

[Prior Art] Conventionally, as a structure of an air-conditioning air outlet in an air conditioner, a fin body for adjusting a blowing direction is provided with a swing shaft, and the fin body is provided with the swing shaft via the swing shaft. A so-called swing louver type in which a fin body is continuously reciprocally swung about the swing shaft by driving a power source such as an electric motor is generally well known. ing.

In addition, in this type of air-conditioning outlet, the air-conditioning air blowing mode is changed automatically and periodically according to the automatic swinging of the fin body, and the fin body direction is manually operated. It is known that the blowing direction can be switched to a fixed mode in which the blowing direction is set and fixed in a desired direction by adjustment (see, for example, Japanese Patent Publication No. 58-4256).

However, when the blowing mode can be switched as described above, the fin body transmits the driving force of the power source to the fin body side when the power source is stopped when switching from the automatic variable mode to the fixed mode. Since the swinging motion is stopped via the power transmission mechanism, in order to manually adjust the orientation of the fin body, the connection between the fin body and the power transmission mechanism is released. It is necessary to provide a clutch mechanism that can swing the fin body by manual force.

In the patent publication relating to the above-mentioned prior art, in order to solve the problems such as troublesomeness and forgetting to turn off due to the manual switching operation of the clutch mechanism, a friction type sliding mechanism or a ratchet wheel is provided at a connecting portion between the power transmission mechanism and the fin body. By adopting an overrunning clutch mechanism such as the above, there is disclosed a structure in which the connection between the both is automatically released in association with the adjustment of the wind direction by the manual operation.

However, in the above-described conventional structure, when manually adjusting the wind direction, it is necessary to overcome the connecting force between the fin body and the power transmission mechanism to move the connecting portions of the two.
If manual adjustment is frequently repeated due to long-term use, the connecting force between the two becomes weak, and the swinging drive of the fin body in the automatic variable mode will be hindered. There is.

With respect to such a problem, the applicant of the present application has proposed in Japanese Patent Application No. 01-47105 an air conditioning blow-out device provided with a biaxial swing louver. That is, by providing the fin body with the first swing shaft serving as the swing fulcrum fixed when driving the power source and the second swing shaft serving as the swing fulcrum fixed during the manual operation, The blower mode can be switched without using the clutch mechanism, and the above-mentioned problems can be solved.

By the way, in an air-conditioning outlet in which two types of vertical and horizontal fins are provided and the direction of the conditioned air can be manually adjusted in both up, down, left and right directions, a dedicated manual operation knob is provided for each of the vertical fins and the horizontal fins. It is generally provided, but in order to avoid the problem of operability deterioration due to individually providing this operation knob, one that allows manual operation for both fins with one operation knob is It is known (see, for example, Japanese Utility Model Publication No. 62-18919 or Japanese Utility Model Publication No. 62-37071).

That is, a horizontal fin is arranged on the front side of a fin body (for example, a vertical fin) provided to be reciprocally swingable by driving of a power source, and an operation knob is slidably fitted in the horizontal fin in the longitudinal direction. At the same time, by configuring the rear end side of this operation knob to engage with, for example, the front end portion of the vertical fin, a single operation knob can be used to operate both fins without affecting the reciprocating swing motion of the vertical fin. Manual adjustment can be possible.

[Problems to be Solved by the Invention] However, in the above-described conventional structure, when the vertical fins are reciprocally rocked in the automatic variable mode, the rocking motion of the vertical fins is directly transmitted to the operation knob. It is said that the operation knob slides along the horizontal fins in conjunction with the reciprocating swing of the vertical fins, and this causes visual discomfort due to unsightlyness during operation in the automatic variable mode and causes early wear of the sliding portion. There was a problem.

By the way, in the above-mentioned two-axis swing louver, one swing shaft (first swing shaft) serves as a swing fulcrum fixed when the power source is driven, so the operation knob is connected to the first swing shaft side. By doing so, it is possible to prevent the swing motion of the vertical fins from being transmitted to the operation knob.

The present invention has been made in view of the above problems, and in an air conditioning outlet having a two-axis swing louver, the operation knob slides in conjunction with the reciprocating swing of the fin body in the automatic variable mode. An object of the present invention is to provide a structure of an operating portion of an air conditioning outlet which can be prevented.

[Means for Solving the Problems] Therefore, the present invention has two types of vertical and horizontal fin bodies for adjusting the left-right and up-down wind directions of the conditioned air, and an operation unit for manually adjusting the directions of these fin bodies. A first swing shaft connected to a first link member that can be manually moved and a second swing shaft connected to a second link member that can be driven by a power source. And the vertical fins swing about the first swing shaft as a fixed fulcrum when the power source is driven, and swing around the second swing shaft as a fixed fulcrum during the manual adjustment. In the swing louver type air-conditioning outlet configured as described above, the first link member is formed of a rectangular frame body, and the frame body is provided with an engaging member having a substantially L-shaped cross section that extends in the vicinity of the horizontal fin. On the other hand, the operating part is longer than the horizontal fin. It is fitted so as to be slidable in the direction, and the engaging member and the operating portion are slidably engaged in the vertical direction.

[Advantages of the Invention] According to the present invention, the operating portion is slidably fitted in the lateral fins in the longitudinal direction (lateral direction), and the operating portion and the frame ( Since the first link member) is slidably engaged in the vertical direction, the horizontal fins can be swung in the vertical direction by rotating the operation portion in the vertical direction when manually adjusting the wind direction. In addition, by sliding the operating portion in the lateral direction, the first link member is moved in the lateral direction via the engaging member, and the second link member is moved.
The swing shaft can be swung laterally with the fixed fulcrum. On the other hand, when the power source is driven, the vertical fins are swung with the first swing shaft as a fixed fulcrum, so that the first swing shaft and the first link member remain fixed. Therefore, the operation portion engaged with the first link member is not slid.

That is, it is possible to manually adjust both vertical and horizontal fins with one operating portion, and it is possible to prevent the operating portion from sliding along the horizontal fins in conjunction with the reciprocating swing of the vertical fins in the automatic variable mode. .

As shown in the figure, a leaf spring 31 having a notch 31b for positioning and an attachment 31a having a predetermined width is attached.

The vertical fins 11, 12, 13 are attached to the louver frame 26, and the leaf spring 31 is attached to the bottom plate 28 to form a unit body. By assembling the unit body in the louver housing 1, The work of assembling the fins 11, 12, 13 can be simplified. At this time, the bottom plate 28 of the louver frame 26 is assembled so as to be fitted into the guide groove 1a formed by the stepped portion provided in the front housing 15 and the front end portion of the rear housing 16 and extending in the left-right direction ( (See FIG. 3).

When the vertical fins 11, 12, 13 swing to the left and right, a force in the left-right direction acts on the louver frame 26 along with the swing motion, and the bottom plate 28 of the louver frame 26 and the guide groove 1a
A frictional force corresponding to the urging force of the leaf spring 31 is generated between and.
With respect to the spring characteristics of the leaf spring 31 and the shape and size of its mounting portion, the sliding frictional force generated at this time is sufficiently larger than the rotational frictional force of the first swing shaft 24 generated by the bearing portions 27h and 28h. Is set in advance.

Further, the upper plate 27 of the louver frame 26 is provided with a substantially triangular overhang portion 27a extending to the front side, and an engaging pin 32 extending downward is fixed to the apex portion of the overhang portion 27a. Is vertically slidably engaged with a two-claw fork portion 10a formed on the rear portion of the operation knob 10 (see FIGS. 2 and 3). Therefore, when the operation knob 10 is slid to the left and right along the horizontal fin 8, the louver frame 26 is moved to the left and right together with the engaging pin 32, and at this time, the vertical fins 11, 12, and 13 are moved to the respective first fins. The two swing shafts 25 are each swung about a fixed fulcrum.

On the other hand, all of the second swing shafts 25 of the vertical fins 11, 12, 13 are
The link member is rotatably supported by a single link member 41 extending in the left-right direction across the rear housing 16.
