Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a holding structure for a wind direction adjustment blade of an air conditioner.

(Prior art) In an air conditioner (for example, a fan coil type), vanes for adjusting the wind direction are provided at the outlet from which hot or cold air heat-exchanged by a heat exchanger is blown out. It is generally well known to try to adjust the wind direction.

The wind direction adjusting blade must be held rotatably (that is, the wind direction can be adjusted) with respect to the mounting part, but a conventionally known holding structure for the wind direction adjusting blade is as shown in FIG. A fan-shaped recess 10' is formed in the side wall of the air outlet 9' to serve as a blade attachment part for holding the end of the blade 11' for adjusting the wind direction, and the inner periphery of the arc is centered around the key part 10a' of the fan-shaped recess 10'. There is a structure in which the blade 11' is configured to be able to rotate along the surface 10b', and the inner circumferential surface 10b' of the arc portion is formed in a wave shape to enable stepwise adjustment of the wind direction. (Refer to Utility Model Application Publication No. 57-162435).

(Problems to be Solved by the Invention) In the case of the above-mentioned known example, since the blade 11' rotates in stages along the wavy arc inner peripheral surface 10b',
There was a problem in that the wind direction adjustment was only performed in stages and the range of wind direction adjustment could not be finely adjusted.
Further, since the structure is such that the end portion of the blade 11' is fitted into the recess 10', if the blade 11' is deformed, there is a risk that the fitting portion may come off.

The present invention has been developed in view of the above problems, and by interposing a new holder using an elastic bush between the wind direction adjusting blade and the blade mounting member, the wind direction can be adjusted arbitrarily. The object of the present invention is to provide a blade holding structure that can be installed reliably and that can be installed reliably.

(Means for Solving the Problems) In the present invention, as a means for solving the above problems, as shown in the attached drawing, hot air or cold air that has been heat exchanged in the heat exchanger 4 is blown out. In a holding structure for a wind direction adjustment blade of an air conditioner in which a blade 11 for adjusting the wind direction provided at the air outlet 9 is rotatably held by blade attachment members 10a and 10b, at the end of the blade 11. Between the support plate 12 protruding approximately perpendicularly to the blade surface and the blade attachment members 10a, 10b, the blade is inserted into the through hole 13 of the support plate 12 and has a flange portion 17 on one end side. and an elastic bushing 15 with a nut 18 embedded in the other end; the nut 18 is inserted into the elastic bushing 15 from the flange portion 17 side;
The support plate 12 is compressed between the elastic deformation portion 15a which is induced to be deformed by the tightening force of the tightening bolt 16 and the flange portion 17. Constructed retainer 14
are intervening.

(Function) In the present invention, the following effects can be obtained by the above means.

That is, the wind direction adjustment blade 11 has an elastic deformation portion 15a that is pressed against both side surfaces of the support plate 12 at the end thereof.
By the frictional force between the flange portion 17 and the flange portion 17, the airflow direction can be adjusted linearly.

Further, by utilizing the elastic deformation of the elastic bushing 15 to secure the contact surface of the blade 11 with the support plate 12, a reliable holding state can be obtained despite the extremely simple structure.
