Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction deflecting device for an air conditioner.

[0002]

2. Description of the Related Art FIGS. 5 to 7 show the structure of a conventional air conditioner and a wind direction deflecting device. Reference numeral 1 denotes an underframe main body, which includes a front grill 2 having a decorative grill 2a and a blower circuit 8. The provided blow-out grill 6 is attached. Inside, a heat exchanger 4 and a blower fan 5 that constitute a refrigeration cycle
Is provided. The blowing grill 6 is provided with a side wall 6a and a hole 6b, and has a fixing portion 7a and a fixing rib 7b.
The cap 7 including the bearing 7c is fixed by pressing the fixing portion 7a into the hole 6b of the blowing grill 6 and fitting the fixing rib 7b and the hole 6b. Reference numeral 3 denotes a vertical wind direction deflection blade, which is incorporated in such a manner that the shaft portion 3a is rotatably inserted into the bearing portion 7c of the cap 7. Here, the cap 7 is provided as a measure against sliding noise when the vertical wind direction deflection blade 3 rotates.

[0003]

However, in the structure as described above, the dimension x1 is secured in order to secure the strength of the shaft portion 3a of the vertical wind direction deflection blade 3 and the rotational stability of the vertical wind direction deflection blade 3. Therefore, the x2 dimension must be increased. Therefore, even if an attempt is made to move the position of the shaft 3a, which is also the rotation center of the vertical airflow direction deflecting blade 3, to the leeward side in order to improve the air volume performance, it is impossible because the outer shape is restricted by design and the x2 dimension becomes small. Or, conversely, to improve the design
In order to ensure the air flow performance even if the position of the shaft is moved to the windward side, when the position of the shaft 3a, which is also the rotation center of the vertical wind direction deflection vane 3, cannot be moved to the windward side, the x2 dimension becomes smaller, so There is a big problem that the arrangement position of the wind direction deflecting blade 3 cannot be changed, and the performance and the design cannot be improved.

Further, since it is assembled only by press fitting,
There has been a problem that the parts incorporated by fitting are loosened and easily come off when a product receives a large impact such as when the product is dropped.

The present invention has been made to solve the above-mentioned conventional drawbacks, and an object thereof is to provide an air conditioner whose air flow performance is improved without changing the design,
It is to provide an air conditioner with improved aesthetics by expanding the degree of freedom in design without deteriorating the air volume performance.

Another object of the present invention is to provide an air conditioner of improved quality in which the parts do not come off even when subjected to a large impact.

[0007]

[Means for Solving the Problems] Therefore, a means for solving the above problems is to fix a fixed part of a shaft having a shaft part and a fixed part by press-fitting in a hole provided in a vertical wind direction deflecting blade, and blow out. The shaft part of the shaft is attached to the bearing part of the side wall of the grill so as to be rotatable.

Further, according to the present invention, a fixing claw is provided on the fixing portion of the shaft.

[0009]

The operation of the above means is as follows.

According to the present invention, a shaft fixing portion having a shaft portion and a fixing portion is fixed by press fitting into a hole portion provided in a vertical airflow direction deflecting blade, and is rotatably attached to a bearing portion of a side wall of a blowing grill. By attaching the shaft part, the structure of the wind direction deflection device becomes compact, and it is possible to improve the air volume performance without changing the design. Also, without lowering the air volume performance, the freedom of design is expanded and the aesthetic appearance is improved. It is possible to improve.

Further, according to the present invention, by providing a fixing claw on the fixing portion of the shaft, it is possible to improve the quality in which the shaft does not come off even if it receives a large impact.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained with reference.

In the figure, reference numeral 1 denotes an underframe main body, to which a front grill 2 and a blowing grill 6 provided with a side wall 6a and a hole 6b are attached. Reference numeral 3 denotes a vertical wind direction deflection blade, which has a hole 3b. Fixed part 9a, fixed rib 9
The shaft 9 provided with b and the shaft portion 9c is press-fitted with the shaft fixing portion 9a into the hole portion 3b of the vertical wind direction deflecting blade 3, and is fixed by fitting the fixing rib 9b and the hole portion 3b. The shaft portion 9c is incorporated in the hole 6b of the blowing grill 6 so as to be rotatably inserted, and constitutes a wind direction deflecting device.

In the above structure, y1 is provided in order to secure the strength of the shaft portion 9c and the rotational stability of the vertical wind direction deflecting blade 3.
If the dimensions are secured and y1 = x1 as in the prior art, y2 ≦ x2 is inevitably possible, and the configuration of the wind direction deflecting device can be made compact.

Next, a second embodiment of the present invention will be described with reference to FIG. Here, the same parts as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the figure, 9d is a fixed claw provided on the fixed portion 9a of the shaft 9, and has a shape such that the shaft portion 9c is caught in the vertical wind direction deflection vane 3 when press-fitting the shaft portion 9c into the hole 3b of the vertical wind direction deflection vane 3. It is composed of dimensions.

In the above structure, in addition to the same effect as the first embodiment, it becomes possible to prevent the shaft 9 from coming off even if it receives a large impact.

[0018]

As is apparent from the above-described embodiment, the present invention fixes the shaft fixing portion having the shaft portion and the fixing portion to the holes provided in the vertical wind direction deflecting blades by press fitting, and the blow grill side wall. By attaching the shaft part of the shaft to the bearing part of rotatably, the structure of the wind direction deflecting device becomes compact. As a result, the air volume performance can be improved without changing the design, and the design flexibility and aesthetics can be improved without lowering the air volume performance.

Further, according to the present invention, by providing a fixing claw on the fixing portion of the shaft, it is possible to improve the quality such that the shaft does not come off even if it receives a large impact.
