JP2000065419A - Wind direction adjuster of air conditioner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide the wind direction adjuster of an air conditioner whose cost is reduced and which is stable in operation by dispensing with conventional adjustment work and facilitating the assembly adjustment work. SOLUTION: A transmission means is made of an engaging projection 13b which projects downward of a change plate 13, and a slot 14a which is made behind the shaft fulcrum 8a of an operation lever 8 pivoted freely of horizontal rotation and engages with that engaging projection. Thereby, the transmission means can transmit the motion of the operation lever 8 directly to the change plate 13 through the engaging projection engaged with the slot, and also absorb the error in attachment of each part by its slot. There is no necessity to adjust the condition of the tension of a connection wire as in the past, and also most parts are set up on an electrical equipment box 7, so this is easy of assembly, and the assembly adjustment time is curtailed sharply. Moreover, the sliding direction of the change plate 13 can also be freely selected back and forth and right and left, so there is freedom in arrangement of parts, too, and the design property is improved.

The operation of the above configuration will now be described. First, the embodiment of FIG. 3 will be described. In the case of the embodiment of FIG. 3, the first connecting rod 11 is arranged so as to move in the left-right direction by the rotational movement of the driving device 10, and the movement of the connecting shaft 11a of the first connecting rod 11 is transmitted through the elongated hole 12b. And transmitted to the second connecting rod 12. Further, the change plate 13 is slidably attached to the upper surface of the electrical component box 7 in the front-rear direction, and its guide hole 13a is disposed in the left-right direction. The rotation range of the second connecting rod 12 is increased when the position of the connection shaft 11a approaches the pivot point 12a, and the rotation range is reduced when the position of the connection shaft 11a is further away. I have. The rotation of the second connection rod 12 is transmitted to the connection plate 9 via the connection shaft 12d and the engagement groove 9b, and the plurality of wind direction plates 2c are rotated according to the movement of the connection plate 9. I have. The rotation of the operation lever 8 can be performed by rotating the pivot 8a, the long hole 14a,
The change plate 13 is transmitted to the change plate 13 via 3b, and the change plate 13 is slid back and forth. At this time, in order to convert the left and right movements of the operation lever 8 into the front and rear movements of the change plate 13, the operation lever 8 is formed to bend in a U-shape with the pivot point 8a as a bending point. Therefore, when the operating lever 8 is turned to the right, the change plate 13 slides forward and the position of the connecting shaft 11a approaches the shaft fulcrum 12a. The turning range of the wind direction plate 2c is widened.

Next, the embodiment of FIG. 4 will be described.
In the case of the embodiment of FIG. 4, the first connecting rod 11 is arranged to move in the front-rear direction by the rotational movement of the driving device 10,
In order to convert the movement of the first connecting rod 11 in the front-rear direction into the movement in the left-right direction, the front part and the rear part of the second connecting rod 12 are substantially 90 degrees in a U-shape with their pivot points 12a as bending points. It is bent. The change plate 13 is slidably mounted in the left-right direction. When the change plate 13 slides to the left, the change plate 13 is arranged in a direction in which the guide hole 13a is separated from the shaft fulcrum 12a. The operation lever 8 is formed to extend substantially linearly behind the shaft fulcrum so that the change plate 13 is slid right and left by the left and right movements of the operation lever 8. Therefore, when the operation lever 8 is turned to the right, the change plate 13 is slid to the left, and the position of the connecting shaft 11a is farther from the shaft fulcrum 12a, so that the turning range of the second connecting rod 12 is narrowed. The rotation range of the linked wind direction plate 2c is reduced.

Next, the embodiment shown in FIG. 5 will be described.
In the case of the embodiment of FIG. 5, similarly to the embodiment of FIG. 4, the first connecting rod 11 is disposed so as to move in the front-rear direction by the rotational movement of the driving device 10, and the first connecting rod 11 is moved in the front-rear direction.

In addition, the change plate 13
The guide hole 13a is slidably mounted in the left-right direction, and is arranged in a direction in which the guide hole 13a is separated from the shaft fulcrum 12a when slid left. When the operation lever 8 is rotated to the right, the gear 1
4b rotates the pinion gear 15 clockwise, and the rotation of the pinion gear 15 moves the change plate 13 rightward through the rack 13c. Therefore, since the position of the connection shaft 11a approaches the shaft fulcrum 12a, the rotation range of the second connection rod 12 is widened, and the rotation range of the wind direction plate 2c interlocked with this is widened.
