Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a fan that blows air out from an outlet at one end of the in-device air path through an in-device air path formed by a casing. The present invention relates to an air flow device in which a lighting lamp is attached to the air outlet portion, and a wind shielding cover is provided to prevent air blown from the fan from hitting the lighting lamp.

[Conventional technology]

Such an air flow device is designed to be integrated with a lighting fixture by attaching a lighting lamp to the air outlet, and in the integration, the air delivered by the fan hits the lighting lamp attached to the air outlet. By providing a wind-shielding cover to prevent the fan from blowing air, it is possible to prevent the accumulation of dust on the lighting lamp and the generation of vibration and vibration noise caused by the fan air blowing into the lighting lamp. Conventionally,
When installing the above-mentioned wind-shielding cover, although the wind-shielding cover is extended downstream in the air flow direction to a position where there is no risk of fan-blown air hitting lighting, etc., The edge of the fence was simply an eave-like cut-off edge with no connection to it (see Japanese Utility Model Publication No. 49-48983).

[Problem that the invention attempts to solve]

However, in the above conventional structure, on the back side of the eave-like edge of the wind shield cover (i.e., the side where the illumination light is arranged), the attraction caused by the flow of air sent out by the fan from the edge of the wind shield cover causes the air flow near the illumination light to A vortex that entrains air is generated, and due to the vortex, there are still problems such as slight vibrations of the device and the accompanying unpleasant vibration noise, and the distance that the blown air reaches is shortened.Furthermore, In an integrated structure with a lighting fixture, there was a problem in that the service life of the attached lighting lamp was shortened due to the slight vibration of the device caused by the above-mentioned eddy current.

The purpose of the present invention is to solve the above problems through rational improvements.

[Means for solving problems]

The characteristic configuration of the air flow device according to the present invention is that a fan is provided for blowing air out from an outlet at one end of the in-device air path through an in-device air path formed by a casing, and illumination is provided at the outlet. In a configuration in which a light is attached and a wind shielding cover is provided to prevent the air blown from the fan from hitting the illumination light, the wind shielding cover continues from the edge of the wind shielding cover and gradually extends from the air flow path toward the downstream side in the air flow direction. The purpose of the present invention is to provide a rectifying cover that surrounds the illumination lamp in a state where it is separated from the lamp, and its functions and effects are as follows.

[Effect]

In other words, in the above characteristic configuration, the airflow guiding action of the wind-straightening cover that surrounds the illumination lamp in a state that extends from the edge of the windshield cover and gradually moves away from the air flow path toward the downstream side in the air flow direction, and the illumination light arrangement portion Due to the partition wall effect, the air blown out from the air outlet part, which flows closer to the wind shielding cover, is directed along the wind straightening cover without forming a vortex that involves the air near the lighting lamp. It can be blown out smoothly.

[Effect of idea]

As a result of the above-mentioned effects, according to the present invention, it is possible to prevent the slight vibration of the device due to the generation of vortices at the edge of the windshield cover and the generation of unpleasant vibration noise accompanying it, thereby improving the environment around the device. It is possible to extend the reach of the blown air, thereby improving the desired air flow performance, and furthermore, by preventing the above-mentioned micro-vibrations, it has also become possible to prevent a reduction in the life of the attached lighting lamp.

〔Example〕

Next, an example will be described.

As shown in FIGS. 1 and 2, a rotating fan 4 is attached to the inside of a cylindrical casing 3 whose upper end opening is an intake port 2 via an electric motor 5 and a motor support rod 6. The fan 5 sucks indoor air from the intake port 2, and the air flow device blows the sucked air into the room from the outlet 8 on the lower end side of the casing through an internal air path formed by the casing 3. be.

In the figure, 1 is a dust removal tool provided at the intake port 2.

An illumination lamp 10 is attached to the air outlet 8 portion while being supported by the casing 3 via a socket 11 and an electric motor 5, etc., and is thereby attached to the ceiling via a mounting member 9 attached to the casing 3 In other words, the air flow device and the lighting lamp 10 can be installed at the same time at a predetermined installation target location, such as the air flow device for the room and the lighting fixture for the room. .

A wind shielding cover 7 is provided inside the casing 3 to surround the lighting lamp 10 so as to prevent the air sent out by the fan 4 from hitting the lighting lamp 10 disposed at the outlet.
By providing a
This is to prevent dust from accumulating on the 0, and from generating vibrations and vibration noise.

Further, at the lower end of the wind shielding cover 7, a wind shielding cover 7 is provided.
A transparent air conditioning cover 14 surrounding the illumination lamp 10 is provided continuously from the edge of the lighting lamp 10 in such a manner that it gradually moves away from the air flow path toward the center of the device as it goes downstream in the air flow direction. Due to the airflow guiding effect and the partitioning effect on the illumination lamp 10, the air sent out by the fan is smoothly blown out without forming a vortex that entrains the air around the illumination lamp 10.

[Another example]

Next, another embodiment will be described.

As shown in FIGS. 3 and 4, the casing 3
is formed into a substantially truncated conical shape whose diameter increases toward the outlet 8 side, and an annular fluorescent lamp 12 for illumination is attached to the outlet 8 portion along the inner circumference of the casing 3. In the configuration, the air delivered by the fan 4 is delivered to the annular fluorescent lamp 1.
A cylindrical windshield cover 7 that prevents wind from hitting the
is installed in the casing 3, and is connected from the edge of the wind shielding cover 7 and surrounds the annular fluorescent lamp 12 in such a manner that it gradually moves away from the air flow path toward the outer periphery of the device as it goes downstream in the air flow direction. 14 may be provided.
