Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air-conditioning air blowing mode blown out from an air-conditioning system, an automatic variable mode for automatically and periodically changing the wind direction, and a manual operation mode. The present invention relates to a swing louver-type air conditioning outlet structure that can be switched to a fixed mode in which the wind direction is set and fixed in a desired direction by adjustment.

[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 wind direction can be switched to a fixed mode in which the wind 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 a first swing shaft that serves as a swing fulcrum when driving the power source and a second swing shaft that serves as a swing fulcrum during manual operation,
The blower mode can be switched without using the clutch mechanism, and the above-mentioned problems can be solved.

[Problems to be Solved by the Invention] However, in the above-described two-axis swing louver, two fin shafts are provided in each fin body, and the respective pivot shafts are connected by link members. Compared with the one-axis type, the internal structure of the air conditioning outlet becomes complicated to some extent, and the work of assembling the fin body on the case side becomes more difficult.

In particular, in order to smoothly and stably adjust the direction of the fin body, it is desirable to provide a guide groove for guiding the sliding movement of the link member on the case side. It is necessary to take measures so as not to complicate the internal structure of the above, or reduce the ease of assembly of the fin body to the case side.

Therefore, the present invention can provide the guide groove with a relatively simple structure in an air conditioning outlet provided with a biaxial swing louver, and can improve the assembling property when the fin body is assembled to the case side. It is an object of the present invention to provide a structure of an air conditioning outlet that can be improved.

[Means for Solving the Problems] Therefore, the present invention provides a first swing shaft connected to a first link member that can be manually operated and a second link member that can be driven by a power source. A plurality of wind direction adjusting fin bodies having a second swing shaft connected thereto are provided, and each of these fin bodies swings with the first swing shaft as a fixed fulcrum when the power source is driven, while manually. At the time of adjustment, at least one of the first and second link members has a rectangular shape in an air-conditioning outlet provided with a swing louver configured to swing with the second swing shaft as a fixed fulcrum. And a case for accommodating the fin body is provided with a groove portion for guiding the sliding movement of the frame body. One side of the groove portion is open toward the outside of the case. Insert another member from the open side of the groove The frame body is slidably positioned and held in the groove portion by being fixedly fitted together.

[Effect of the Invention] According to the present invention, at least one of the first and second link members is formed of a rectangular frame body, and a groove portion of which one side is open toward the outside of the case is formed. Since the frame body is slidably positioned and held in the groove portion by being provided in the case and another member is fitted and fixed from the opening side of the groove portion, a plurality of fin bodies are previously attached to the frame body. After assembling and unitizing, this unit is assembled in the groove of the case, and then the other member is fitted and fixed to the case from the opening side of the groove,
The frame body (that is, the fin body) can be assembled to the case side relatively easily. Further, the guide groove of the frame body can be formed with a simple structure.

That is, without inviting the internal structure of the outlet to be complicated,
The workability of assembling the fin body on the case side can be improved.
