Abstract

PURPOSE:To lessen driving sources and to reduce the number of components by a method wherein the rotational force of one rotational driving means is divided by a dividing means and thereby two sorts of louvers are shaken. CONSTITUTION:A plurality of vertical louvers 2 being first louvers and two horizontal louvers 3 being second louvers are provided at an outlet, and a driving mechanism 4 is linked to each of the louvers 2 and 3. The vertical louvers 2 are provided virtually from the upper to lower ends of the outlet and also disposed at equal intervals virtually in the lateral direction of the outlet. Conditioned air such as cooled air obtained by heat exchange, for instance, is blown off therefrom. When a rotational driving means 5 is operated, on the other hand, the rotational force of this means 5 is transmitted to a dividing means 6, which divides the rotational force and gives the divided forces to a first takeout element 62a and a second takeout element 63a. The rotational force taken out of the first takeout element 62a is transmitted to a first swinging means 7 and the rotational force taken out of the second takeout element 63a to a second swinging means 8 respectively.

It is divided into 3a).

The first swing mechanism (7) engages with the drive gear (62) and each vertical louver (2), (2), . . . It is made up of a driven gear (71) and a connecting rod (72). The driven gear (71) is composed of a bevel gear that constantly meshes with the drive gear (62), and has a pin (73) on the outer periphery of the back surface.

Further, the connecting rod (72) is formed with a gear side slider frame (74) and a louver side slider frame (75), and the gear side slider frame (74) is connected to the back surface of the driven gear (71). The above pin (73) is provided in parallel.

Further, the louver side slider frame (75) is provided above the rear end of each vertical louver (2), is formed in the front-rear direction of the air outlet (13), and is located behind each vertical louver (2). A pin (76) protruding from the upper end is inserted, and the linear movement of the connecting rod (72) causes each vertical louver (2), (2),...

) and consists of a gear train. The large-diameter driven gear (82) is attached to the horizontal pin (32), while the small-diameter driven gear (81) intermittently meshes with the partial gear (63) as the partial gear (63) rotates. However, the horizontal louvers (3), (3) are cautioned to swing.

Next, the operation of the drive mechanism (4) will be explained.

First, when one stepping motor (5) is driven,
As the drive shaft (61) rotates and the drive gear (62) rotates, the partial gear (63) also rotates. The rotation of the driving gear (62) causes the driven gear (71) of the first swing mechanism (7) to rotate, thereby driving the stepping motor (5).
A portion of the rotational force is extracted, and the pin (73) protruding from the driven gear (71) rotates. This pin (73)
moves within the gear side slider frame (74) at the same time as it rotates,
The connecting rod (72) performs reciprocating linear motion in the axial direction, as shown in FIGS. 2 and 3. By moving the connecting rod (72), each vertical louver (2), (2),
The pins (76) of ... move in the left and right direction while moving within the louver side slider frame (75), and each vertical louver (2),
(2), ... are vertical pins (21), (21), ...
It swings left and right around ....

On the other hand, the partial gear (63) rotates around the axis of the drive shaft (61), and as shown in FIG. 6, for example, the partial gear (63) does not mesh with the small-diameter driven gear (81). In this state, the horizontal louvers (3) (3) are positioned horizontally (see Fig. 6(a)), and when the partial gear (63) rotates from this state and meshes with the small diameter driven gear (81), the small diameter drive The gear (81) rotates, the large diameter driven gear (82) rotates, the horizontal pin (32) rotates, and the horizontal louver (3) (3) rotates.
swings upward (see FIG. 6(b)).

Subsequently, when the partial gear (63) rotates, the partial gear (63) is disengaged from the small diameter driven gear (81) (see Fig. 6).
See C), horizontal louver (3).

(3) maintains an upward state. Thereafter, when the stepping motor (5) is reversely rotated, the above-mentioned operation is performed in reverse, and the horizontal louvers (3), (3) return to the horizontal state. The horizontal louver (3) is created by forward and reverse rotation of the stepping motor (5).

(3) intermittently swings up and down around the horizontal pin (32). Note that the vertical louvers (2) and (2) change depending on the forward and reverse rotation angle of this stepping motor (5).

The swing angle of ... will change.

The blowing direction of the conditioned air is changed by the rocking of each of the louvers (2) and (3).

Therefore, the rotational force of the one stepping motor (5) is divided by the dividing mechanism (6), and both louvers (2), (3
) to swing, two types of louvers (2
) and (3) are swung by a single drive source, the number of drive sources can be reduced compared to the conventional method, and the number of parts can be reduced, making it possible to make it cheaper. . Furthermore, since the installation space for the stepping motor (5) can be reduced, the entire device can be downsized. Furthermore, since the swinging of both louvers (2) and (3) can be controlled by driving and controlling only one stepping motor (5), the control system can be simplified.

Also, the various gears (62) and (63) mentioned above.

(71), (81), and (82), the rotational force can be reliably divided and taken out, and each louver (2) and (3) can be swung with high accuracy. , it is possible to make precise changes in wind direction.

Further, one end of the drive shaft (61) is connected to the stepping motor (5) as in the previous embodiment, while the other end (61) is connected to the stepping motor (5) as in the previous embodiment.
1a) is configured in the second attachment part of the rotational force.

Further, the first swing mechanism (7) is configured in the same manner as in the previous embodiment, and is configured such that the fan-shaped gear (64) intermittently meshes with the driven gear (71). On the other hand, the second rocker tJt(8) is located at the end (6a) of the drive shaft (61).
A cam (83) is attached to the cam (63).
A connecting pin (84) is configured to protrude from the. There is a long hole (85) in the side plate (31) of the horizontal louver (3).

) rotates, the connecting pin (84) rotates, and the horizontal louver (
2), (2) swings up and down.

On the other hand, the sector gear (64) rotates due to the rotation of the drive shaft (61), and the driven gear (7) of the first swing mechanism (7)
1), and the connecting rod (72) moves intermittently to move the vertical louver (2).
