Abstract

PURPOSE:To enable a clear displaying of air direction to be performed by a method wherein a light beam is projected in a direction of blown air flow with a signal from an air direction changing means. CONSTITUTION:When an air direction is set by a setting part 1, a deviation angle of guide vanes 2 is adjusted to a set angle at a control part 3, and then the air flow is blown in such a direction as above. When it is desired to know an air direction, the air direction is instructed at an input part 4, resulting in that a light beam generated at a light emitting part 5 is adjusted at a control part 7 in such a way that it becomes parallel with the direction of the guide vanes and then projected.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an air conditioner having a wind direction display function.

2. Description of the Related Art A conventional air conditioner having this type of wind direction display function has, for example, a string or strip of paper 9 attached to the air outlet 8 as shown in FIG.
This may be due to the condition of the guide vanes 2 at the air outlet. In the case of the former, the direction of the wind can be determined by visually observing the direction in which it flutters. In the latter case, the guide vane 2
The wind direction can be determined by visually observing the deflection angle.

Problems to be Solved by the Invention However, in the former case, the threads and paper at the outlet are cut or soiled by the air flow, and the appearance is not good. Furthermore, in the latter case, the guide blades are often not clearly visible due to the configuration of the equipment, making it difficult to confirm the wind direction.

The present invention solves the conventional problem M, and aims to display the wind direction display in a more visually understandable manner.

Means for Solving the Problems In order to achieve the above object, the present invention provides a wind direction changing means for changing the direction of the airflow blown from the wind blowing means, and a projection for projecting a light beam based on a signal from the wind direction changing means. A light means is provided.

Function The present invention has the function of clearly indicating the wind direction by projecting a light beam in the direction of the blown airflow.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a schematic diagram of one embodiment of the invention.

1 is a setting part for setting the wind direction, 2 is a guide blade, 3 is a setting part 1
a first control unit that controls the deflection angle of the guide vane 2 based on a signal from the input unit; 4 is an input unit that commands a light projection display; 5 is a light emitting unit;
7 is a projection unit that projects the light beam from the light emitting unit 5, and 7 is an input unit 4.
The projection unit 6
This is a second control unit that fully controls the projection angle of the image.

In the above configuration, when the wind direction is set in the setting section 1, the first
The control unit 3 adjusts the deflection angle of the guide vanes 2 to a set angle, and the airflow is blown out in that direction.

Next, when you want to know the wind direction and you are instructed to display the wind direction using the input unit 4, as shown in FIG. It has the effect of being adjusted and projected by the control unit 7. As another method of controlling this light beam, as shown in FIG. 3, it is also conceivable to control the projection angle of the projection section 6 by the second control section 7 so that the light beam scans the region where the blown airflow is diffused. Also,
The projection of the light beam may be started automatically in synchronization with the setting of the wind direction. communication between the setting unit 1 and the first control unit 2;
Communication between the input section 4 and the second control section 7 and communication between the first control section 2 and the second control section 7 are performed by wire or wirelessly, respectively.

According to the above operation, the wind direction can be determined with certainty, and since light rays are used, there is also a visual aesthetic effect. We believe that a laser beam with an intensity that does not cause harm to the human body is appropriate. Furthermore, by using visible light that has a radiation effect, such as exothermic light, it is possible to have a heating effect in addition to the wind direction display function.

Effects of the Invention As described above, according to the air conditioner of the present invention, it is possible to know the wind direction with certainty, and since it uses light rays, it also has a visual aesthetic effect.
