Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a diffusion plate device for an air-conditioning outlet, which is attached to an air-conditioning outlet and diffuses conditioned air blown out from the air-conditioning outlet so as to eliminate the adverse effects of downdraft.
[0002]
[Prior art]
Conventionally, in air-conditioning equipment such as offices, the angle of the blowing air is adjusted by changing the angle of the wing attached to the slot type air-conditioning outlet that blows out air from the elongated slot. Since it is installed inside a slot type air-conditioning outlet, there is a limit to the range in which the wind direction can be changed depending on the wing angle. For this reason, it is not possible to eliminate the adverse effects that cause physical malfunctions such as “cold” and “hot flash” caused by downdrafts. However, if a stop plate is inserted in the air outlet, not only ventilation and other air conditioning functions will be degraded, but the wind of other air outlets that are linked will become stronger, which may cause secondary problems. It was.
[0003]
On the other hand, there is a detachable air conditioner wing that is attached to the movable air outlet of the air conditioner (see Patent Document 1). The present invention is a wing plate that is attached to a movable air outlet of an air conditioner. This plate is merely a rectangular plate cut into a rectangular shape, and as shown in FIG. In this case, the wind is simply directed in the horizontal direction, and if it is directed in the ceiling direction or downward, the conditioned air or reflected airflow directly hits a person in the direction of the wind, so the downdraft It is considered that the same harmful effect cannot be completely eliminated.

[Problems to be solved by the invention]
In order to solve the above problems, the present invention does not block the air outlet, blocks the downdraft, minimizes the deterioration of the air conditioning efficiency, and has a good appearance without impairing the view of the room. An object of the present invention is to provide a diffusion plate device for an air-conditioning outlet that eliminates the above-described adverse effects caused by the draft.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is an apparatus for diffusing the air-conditioning air current blown out from the air outlet, which is attached below the air outlet of the air conditioner, and the cross section has a wave shape. A diffusion plate and a fixture for attaching the diffusion plate are provided, and the ridges and valleys of the diffusion plate are arranged in parallel and alternately continuously, and both end portions of the wave shape are configured toward the ceiling side. A diffusion plate device for an air-conditioning outlet characterized by the above (claim 1).
[0007]
In order to solve the above-mentioned problems, the present invention provides the air-conditioning outlet of the air-conditioning outlet, wherein the diffuser plate has a symmetrical wave shape in cross section. it is preferable that the diffuser device (claim 2).
[0008]
In order to solve the above-mentioned problems, the present invention provides a plate spring type fixture, wherein the fixture is a leaf spring type fixture, and both ends of the plate spring type fixture attached to one side of the diffusion plate are connected to the tip of the outlet. It is preferable that the diffuser device for the air-conditioning outlet is detachably hooked to and attached to the section ( Claim 3 ).
[0009]
[Action]
The diffusion plate device for an air-conditioning outlet according to the first aspect of the present invention is attached below the outlet as described above. As shown in FIG. 3, the conditioned air blown from the outlet is ridge of the diffusion plate. The downflow that flows from the portion 10 toward the valley portion 11 , rises again from the valley portion and becomes upstream, the upstream portion collides with the ceiling to become a reflected flow, and the reflected flow is widely diffused along the ceiling. A series of winds consisting of the above-mentioned downflow, upstream, and reflected flow flows along a wave-shaped curved surface, so that the wind not only diffuses in the horizontal direction but also diffuses in a vertical direction, It changes to a soft touch and acts to relieve irritation.
[0010]
In the diffusion plate device for an air-conditioning outlet according to the invention described in claim 2, since the both ends of the wave shape of the diffusion plate are configured toward the ceiling as described above, the wind is blown toward the ceiling. , To spread more widely.
[0011]
In the diffusion plate device for an air-conditioning outlet according to the invention of claim 3, since the wave shape of the diffusion plate is configured symmetrically as described above, the central portion of the diffusion plate is positioned at the center of the outlet. If installed, the wind is distributed almost evenly on the left and right, and diffuses to make the room temperature uniform.
[0012]
The diffusion plate device for an air conditioning outlet according to the invention of claim 4 is provided with the leaf spring type fixture as described above, so that both arm portions of the leaf spring type fixture are narrowed by hand, and the slot type air conditioner is provided. If you put it inside the air outlet and release your hand, the arm part spreads by the repulsive force of the leaf spring, the tip part is hooked in the gap, and the diffusion plate can be easily attached, and it can be removed easily by operating in reverse . Since it is a leaf spring type, it can be handled even if the groove width and type of the air conditioning outlet are slightly different.
[0013]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a diffusion plate device for an air conditioning outlet according to an embodiment of the present invention, and FIG. 2 is a side view showing the diffusion plate device for an air conditioning outlet according to an embodiment of the present invention. 3 is a conceptual diagram showing the flow of conditioned air when the diffuser device for an air conditioning outlet according to an embodiment of the present invention is in use. In the figure, reference numeral 1 denotes a diffusion plate device for an air-conditioning outlet, which comprises a diffusion plate 2 and a leaf spring type fixture 3.
[0014]
The diffusion plate 2 in this embodiment is a corrugated plate made of plastic, and has a shape in which the corners of the letter W in the cross section are rounded. The material is not particularly limited, but it can be transparent or colored using lightweight plastics or light metals that have relatively heat resistance, and has flame resistance or flame resistance that conforms to the Fire Service Act. Is preferred. Moreover, it is preferable that the cross section of the diffusion plate 2 has a wave shape, is symmetrical, and both ends are upward in the ceiling direction.
