Description

[Detailed Description of the Invention] The present invention relates to a wind direction display device that displays the direction (angle) of wind blown out from an air conditioner or the like.

Conventionally, when moving the wind direction change plate dynamically using an electric motor or the like, or when attempting to remotely control the wind direction change plate using a remote control, etc., when moving the wind direction change plate,
There was a drawback that it was difficult to tell which direction (angle) this wind direction change was facing.

In view of the above-mentioned drawbacks of the prior art, the present invention makes it possible to easily change the wind direction by making the angle of the wind direction changing plate visible.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Figure 1 shows an air conditioner 1 equipped with the wind direction display device of the present invention.
This shows that.

A wind direction changing plate 3 is provided at the air outlet 2 of the air conditioner 1. By rotating and tilting the wind direction changing plate 3 around shafts 4.4 provided at both left and right ends, the air outlet 2 can be changed. The wind direction changes.

Further, reference numeral 5 denotes a wind direction display device, which is provided at a location in the air conditioner 1 that is easily visible from the outside, and in this embodiment, is provided at the lower right portion of the front surface of the air conditioner 1.

6 is an air suction port provided in the air conditioner 1.

Next, the configuration of the wind direction display device 5 will be explained with reference to FIGS. 2 to 4.

The front cover 7 of this wind direction display device 5 has five radial slits 8 centered at the upper right.

Inside the wind direction display device 5, fifteen edgelight generators 9 are arranged radially in a manner similar to the slits 8, facing each of the slits 8.

An end face 9a perpendicular to the radiation direction and an inclined end face 9b are formed at the end of the edge light generator 9 in the radial direction, and a light emitting element 10.
11 are provided.

The light emitting element 10 facing the right-angled end face 9a is a light emitting element for cooling, and the light emitting element 11 facing the inclined end face 9b is a light emitting element for heating.

Reference numeral 12 denotes a partition member provided further outward from both the light emitting elements 10 and 11.
．． A plurality of partition plates 13 for partitioning the partition plate 11 from the others are protruding from each other.

This partition plate prevents light from each light emitting element 10, 11 from reaching an undesired end face of the edge light generator 9.

Note that the light emitting color of the cooling light emitting element 10 is, for example, blue,
The emitted light color of both light emitting elements is different, for example, the emitted light color of the heating light emitting element 11 is red.

Further, the end surface 9a of the edge light generator 9 forms a light entrance surface for receiving and admitting light from the cooling light emitting element 10,
The end surface 9b forms a light entrance surface for receiving and letting in light from the heating light emitting element 11.

When the cooling light emitting element 10 or the heating light emitting element 11 emits light, the light that enters the edge light generator 9 is diffusely reflected.

Therefore, light is projected onto the slit 8 of the front cover 7 provided on the front surface of the display device 5.

Therefore, only the portion of the edgelight generator 9 facing the light emitting element that has emitted light is displayed linearly.

Here, the slit 8 is set to be located at the center of the edgelight generator 9.

In addition, processing is performed to block light except for the slit 8 portion.

Next, the relationship between the wind blowing direction and the blinking state of the light emitting element will be explained with reference to FIGS. 5 and 6.

As shown in FIG. 5, the wind direction changing plate 3 is connected to a stepping motor 14, and rotates continuously or intermittently in a reciprocating manner within a predetermined angle range.

That is, the wind direction changing plate 3 and the stepping motor 14
and form an automatic wind direction change mechanism.

Here, the relationship between the rotation of the stepping motor 14 and the lighting of the cooling light emitting element 10 and the heating light emitting element 11 is as follows.
Based on the electronic control circuit shown in the figure.

That is, during cooling or heating, the stepping motor 14 rotates according to the number of pulses sent from the microprocessor 15. When the number of pulses corresponding to a certain rotation angle is sent at this time, the light emitting element according to the number of pulses is activated. Turn on the light.

Note that 16 shown in FIGS. 3 and 4 is a spacer provided between the edge light generators 19 and 9.

Therefore, the rotation of the stepping motor 14 changes the direction (angle) of the wind direction changing blades, thereby changing the wind direction.

The slit 8 of the display device 5 is displayed by a light emitting element corresponding to that direction (angle).

Also, during cooling, one light emitting element 10 displays one slit 8, and during heating, one light emitting element 11 displays slit 8 on two adjacent edge light generators 9.
Two lines are displayed.

At this time, the color becomes different during cooling and heating.

From the above, the air conditioner wind direction display device of the present invention displays the direction of the wind blown from the main body of the air conditioner to the outside of the main body. , can be seen visually.

In addition, the display is electrically controlled, so the response is fast.
There is no misalignment between the direction (angle) of the wind direction changing blade and the display.

Furthermore, since the display is not performed by mechanical operation, the display section can be made smaller and thinner.

Also, among the multiple Edgelight generators of the wind direction display device, only one Edgelight generator that corresponds to the wind blowing direction lights up during cooling operation, and two Edgelight generators that correspond to the wind blowing direction illuminate during heating operation. By making the edgelight generator shine, it is possible to easily distinguish whether the operating state is cooling mode or heating mode.

In addition, by distinguishing the emitted light color of the light emitting element between the light emitting element for cooling and the light emitting element for heating, it is possible to more easily recognize which operation is being performed, cooling or heating.
