Description

[Detailed description of the invention] (Technical field) The present invention relates to a wind direction changing device installed at the outlet of a blower device such as an air conditioner, and particularly relates to a wind direction changing device that changes the wind direction by rotating a louver. It is.

(Prior art) Generally, this type of wind direction changing device is designed to determine the current wind direction by visually checking the direction of the louver. This made it inconvenient to determine the direction of the wind.

(Purpose) This proposal was made in view of the above points, and by forming at least a part of the louver from a translucent member and allowing light to pass through the translucent member to cause the member to emit light, it can be used even in the dark. The direction of the louvers can be visually confirmed, making it easy to determine the direction of the wind.

(Example) An example of the present invention shown in the drawings will be described in detail below.

Reference numeral 1 indicates a frame body disposed at the outlet of the blowing device; 2 indicates a plurality of louvers that are pivotally installed within the frame body 1 and change the wind direction by swinging from side to side; at least one of the louvers 2 is a third louver; It is configured as shown in the figure, and the configuration will be explained in detail later. Reference numeral 3 denotes a fan that is rotatably mounted on one side of the frame body 1 and rotates by receiving the wind from the blower device. A power transmission mechanism is interposed between the fan 3 and the louver 2 to swing the louver 2 from side to side as the fan 3 rotates.

The power transmission mechanism includes a connecting plate 4 for interlocking each louver 2, a crank 5 connected to one end of the connecting plate 4 and swinging the louver 2 via the connecting plate 4 by rotation, and a fan 3 for the crank 5. and a deceleration mechanism section 6 that decelerates and transmits the rotation of.

Reference numeral 7 designates a stopper which can be freely engaged with and disengaged from the outer circumferential portion of the fan 3 and prevents rotation of the fan 3 by engaging therein, and 8 is an operation knob located on the front surface of the frame body 1 for operating the stopper 7.

Next, in FIG. 3, the louver 2 is composed of a base portion 2a made of a non-transparent material, and a light emitting portion 2b made of a transparent material on the front edge side of the base portion 2a.
The base portion 2a and the light emitting portion 2b are each provided with a shaft 2 of the same material.
c, 2d are provided protrudingly. The louver 2 is pivotably mounted on the frame 1 with shafts 2c and 2d, and a light source 9 such as a lamp is disposed opposite to the end surface of the shaft 2d. Light from this light source 9 is transmitted through the light emitting section 2b via the shaft 2d, causing the light emitting section 2b to emit light. The thickness of the light emitting part 2b appears thinner or thicker depending on the rotating position of the louver 2, that is, the orientation of the louver 2, and the orientation of the louver 2 can be confirmed by this change in thickness. . Note that the depth dimension of the light emitting portion 2b is gradually increased toward the lower end, and this is for the purpose of easily determining whether the light-emitting portion 2b is facing right or left.

In the above configuration, if the operating knob 8 is now slid to the left in FIG. 1 and the stopper 7 is disengaged from the engagement position with the fan 3, and the blower is operated, the fan 3 will be forced to move the air from the blower. This causes the louver 2 to swing from side to side via the power transmission mechanism, and the wind is directed left and right as the louver 2 swings.

In addition, when fixing the wind direction to a desired direction, press the operation knob 8 when the louver 2 faces the desired direction.
1 to the right in Fig. 1, and press the stopper 7.
When the fan 3 is engaged with the fan 3, the rotation of the fan 3 is prevented, and the swinging of the louver 2 is also stopped while facing the desired direction, so that the wind direction is fixed in the desired direction.

In this embodiment, the movement and orientation of the louver 2 can be easily determined even in the dark by observing the change and state of the light emitting portion 2b of the louver 2.

In the above embodiment, the wind power of the blower is used as the drive source for the louver, but a small low-speed motor may also be used as the drive source. Furthermore, the present invention is not limited to automatically changing the wind direction by swinging the louver, but may also be one in which the wind direction is changed by manually rotating the louver in an arbitrary direction, and is not limited to automatic or manual operation. It's not even a thing. It goes without saying that the present invention may be modified and implemented as appropriate without departing from the spirit of the invention.

(Effects) As described above, according to the configuration of the present invention, the direction of the louvers can be visually confirmed even in the dark, and the direction of the wind can be easily determined, and the inconveniences of the conventional system can be solved.
