DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for closing an air outlet of an air conditioner, or adjusting a wind direction of air blown from the air outlet to a desired direction.
In addition, the present invention relates to an improvement of a wind direction adjustment mechanism used to periodically change the wind direction of the air.

[0002]

2. Description of the Related Art A wind direction switching plate (wind shield plate) having a length extending over an air outlet of an air conditioner is rotatably mounted on the air outlet so that the direction of air blown from the air outlet can be changed. As an air conditioner that can be changed, for example, Japanese Utility Model Publication No.
0243.

[0003]

However, in such a conventional air conditioner, the rear end of the arm having the front end integrally joined to the back surface of the wind direction switching plate is turned to the frame constituting the outlet. Since the wind direction switching plate is rotated about the rear end of the arm so as to be movably assembled, the wind direction switching plate is a circular arc having a small curvature (a circular arc having a larger diameter). The more you try to move along, the longer the arm must be,
In addition, it is difficult to simply and compactly configure a mechanism for adjusting the wind direction and the like and the air conditioner itself using such a wind direction switching plate.

Further, in such a conventional method, the wind direction switching plate can simply be rotated along a circular arc around the rear end of the arm.

[0005] In view of the above, the present invention provides a simple and compact structure of a baffle plate that can block the air outlet of an air conditioner or change the direction of air blown from the air outlet. It is an object of the present invention to be able to be movably provided in a mouth.

8b is provided with a fitting hole 18c at one end of the shaft 5. The cover plate 11 constituting the drive unit 1 is provided with a hole 11b from which the shaft portion 18b of the additional drive gear 18 projects.

The bearing rotator 27 is provided along the rotation axis of the bearing rotator 27.
A shaft 27b protruding from one end face (the end face facing the lid plate 21) is formed, and a fitting hole 27c at the other end of the shaft 5 is provided in the shaft 27b. Further, the cover plate 21 constituting the driven unit 2 is provided with a hole 21b from which the shaft portion 27b of the bearing rotating body 27 projects.

In this embodiment, the additional drive gear 18 is inserted into a hole for inserting the shaft portion 18b of the additional drive gear 18 provided on one of the pair of side panels P ', P'. The drive unit 1 is mounted with the shaft portion 18b of the shaft 18 inserted therein, and the shaft portion 27b of the bearing rotating body 27 provided on the other of the pair of side panels P ', P'. The driven unit 2 is mounted in a state where the shaft 27b of the driven gear 24 is inserted into the hole for inserting the driven gear 24, and further, the shaft of the additional drive gear 18 of the driving unit 1 mounted in this manner. One end of the shaft 5 is fitted into the fitting hole 18c formed in the shaft 18b, and the shaft 27 of the bearing rotating body 27 of the driven unit 2 attached in this manner.
The other end of the shaft 5 is fitted into a fitting hole 27c formed in the b, and the additional drive gear 18 and the bearing rotating body 27 are connected.

As a result, in this embodiment,
The shaft 5 can be rotated by an additional drive motor constituting the drive unit 1, and the wind direction changing plate 6 provided on the shaft 5 is closed by the wind shield plate 3 at the outlet F. The direction of the air blown from the outlet F can be adjusted.

[0079]

According to the air direction adjusting mechanism for an air conditioner according to the present invention, the air outlet of the air conditioner can be closed or the air direction of the air blown from the air outlet can be changed. The movement of the wind plate is performed by a band-shaped rack guided by guide grooves provided in the drive unit and the driven unit, and a drive gear and a driven gear that mesh with the teeth of the band-shaped rack, and the windshield is provided. Since there is no need for a member such as an arm for supporting the wind shield between the plate and the rotation center of the wind shield, the wind shield is moved to the outlet with a simple and compact structure. It can be freely installed.
