Then light of a light emitting element 13 transmitting a polarizing element 15 through the slit 12a is discharged in front of a cover 6. In other word, as the pulley 7 is provided on the axis part 4a of the deflecting plate 4 of the air flow direction, through which a deflecting motion turned into linear motion through the wire 9 is transmitted to the rotary disc 12 wherein the linear motion is converted into rotary motion, display of the air flow direction becomes possible even in case of operation of the deflecting plate 4 of the air flow direction manually.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a wind direction display device that displays the direction (angle) of wind blown out from an air conditioner, etc., and it simplifies the drive configuration, reduces failures, and reduces costs. The present invention provides a wind direction display device that can be created.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In FIG. 1, reference numeral 1 denotes an air conditioner main body, and an inlet 2 and an outlet 3 are formed on the front surface of the main body. Reference numeral 4 denotes a wind direction changing plate provided at the air outlet 3, and this wind direction changing plate 4 can be operated manually or connected to an electric motor (Nutesoping motor) provided inside the air conditioner main body 1 via a speed reduction mechanism. , which rotates continuously or intermittently in a reciprocating manner within a predetermined angular range. Reference numeral 5 denotes a wind direction display device provided on the front surface of the air conditioner main body 1, which displays the angle at which the wind is blown by the wind direction changing plate 4.

Next, the second part about the wind direction change plate 4 and the wind direction display device 5.
This will be explained with reference to the diagram. Here, the same parts as in FIG. 1 are given the same numbers and the explanation is omitted.

In the figure, a shaft portion (not shown) at one end of the wind direction changing plate 4
is rotatably supported by the air conditioner main body 1 via a bearing, and the shaft portion 4a at the other end has a differential fixed thereto and is connected to a speed reduction device 8. 7a is a pin provided on the pulley 7, and 9 is a wire made of a spring wire, one end of which is connected to the pin 7N. Here, the wire 9 is covered with a flexible vinyl tube 10 and freely slides inside the vinyl tube 10. This vinyl tube 10 is fixed at several locations by appropriate means. The material of the vinyl pipe 10 may be resin or metal. Reference numeral 11 denotes an electric motor (stemping motor) that rotates the wind direction changing plate 4 and the pulley 7 via a reduction gear device 8 consisting of a large number of gears, etc., and is operated in reciprocating rotation continuously or intermittently according to signals from the control section. I do. Here, the description of the control unit will be omitted since it is not the gist of the present invention.

The wind direction display device 5 includes a cover 6 provided with display characters, patterns, etc., and a substrate 5a covered with the cover 6. A rotating plate 12 is rotatably supported by the substrate 6a, and a peripheral wall 12b having a light-transmitting ring 1211 is provided on a part of its outer periphery.

Here, the other end of the wire 9 is connected to a pin 120 provided on the rotating plate 12. Reference numeral 13 denotes an LE located within the peripheral wall 12b of the rotating plate 12.
The D light emitting element is fixed to the substrate 14 and is configured not to rotate when the rotary plate 12 rotates. The LED light emitting element 13 emits light during cooling and heating operations. 15 is a polarizing element having prism-like properties;
The light emitted from the LED light emitting element 13 only from the ring 12a provided on the rotary plate 12 is refracted, and the light is transmitted to the display side (front surface) of the cover 6. This polarizing element 15
As shown in the figure, multiple are arranged at regular angular intervals,
As the sulin 12a rotates, light from the light emitting elements 13 is transmitted. Here, the cover 6 prevents the light emitted from the light emitting element 13 from being transmitted from parts other than the light emitting element 12a, and ultimately
The light transmitted through the air conditioner is emitted through the cover 6, and the user of the air conditioner can use this light to determine the direction (angle) of the wind blown out from the air conditioner outlet 3 through the wind direction change plate 4. This can be clearly confirmed.

The operation of the above configuration will be explained.

First, the electric motor (stemping motor) 11 which is the driving source
When the wind direction changing plate 4 is rotated in a direction in which the wind direction changing plate 4 faces downward in response to a signal from the control unit, the wind direction changing plate 4 and the pulley 7 are rotated via the reduction gear, and at the same time the pin fixed on the circumference of the pulley 7 is rotated. The wire 9 with one end connected to the wire 7a is pushed downward and slides inside the vinyl tube 1o, and the slit rotary plate 12 connected to the other end of the wire 9 is rotated to the left in FIG. Then, the sulin H2a of the rotating plate 12 rotates downward, and the light emitted from the light emitting element 13 passes through the slit 12a, passes through the polarizing element 15 close to the slit 12a, and is emitted to the front surface of the cover 6.

Therefore, as a structure for transmitting the wind direction angle of the wind direction changing plate 4 to the wind direction display device 5, the rotating shaft portion 4a of the wind direction changing plate 4 is
A pulley 7 is installed in the wind direction display device, and this rotary motion is changed into a linear motion via a wire 9 covered with a vinyl tube 10, and transmitted to the rotary plate 12 of the wind direction display device, where the linear motion is again converted into a rotary motion. The wind direction angle can also be displayed when the wind direction change plate 4 is manually operated. Furthermore, the power transmission structure is extremely simple, the wind direction and angle are transmitted very reliably, and the number of parts is extremely small, reducing costs, and the wind direction display device is easy to assemble and has fewer failures. is obtained.

In addition, in this embodiment, the rotation plate 12 is
The light passing through & is continuously refracted by a plurality of polarizing elements 15, but as shown in FIG.
Similar effects can be obtained even if the display is continuously performed using a single polarizing element 15 that moves with rotation.

As is clear from the above embodiments, the wind direction display device for an air conditioner according to the present invention allows the wind direction from the outlet to be visually checked by the wind direction display device.
Confirmation is extremely easy, and since the rotation of the wind direction change plate is transmitted to the rotating body of the display device using a single wire,
The interlocking structure of the wind direction change plate and the rotating body is extremely simple, and there are few failures, and it can be manufactured at low cost. By adjusting the length of the wire rod, the deviation of the display position between the wind direction change plate and the display device can be adjusted. It has various advantages, such as the fact that it can be done easily and there is no need to worry about coming back.
