BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a far-infrared radiant heater having a lighting function for heating and illuminating a room by radiant heat (far-infrared) emitted from a heat radiating tube and light rays of a fluorescent lamp. Specifically, the present invention relates to a ceiling-mounted far-infrared radiant heater with a lighting function that is suitable for being hung from the ceiling of a factory or the like.

[0002]

2. Description of the Related Art Far-infrared radiation for heating by using radiant heat (radiant heat) radiated from a heat radiating tube by supplying white kerosene to a combustor, burning the same, and guiding the combustion gas to the heat radiating tube. There are various types of heaters with various structures depending on their use.Especially for large facilities such as factories and gymnasiums, a radiation tube is piped inside a reflection case body that opens downwards. The ceiling-mounted far-infrared radiant heater, which is used by suspending the ceiling on the ceiling, is widely used.

On the other hand, a large number of lighting fixtures are provided on the ceiling surface of facilities such as factories and gymnasiums. If these lighting fixtures and the above-mentioned heaters are separately mounted on the ceiling surface or suspended, the work is extremely difficult. Since it is complicated, and the appearance may be bad and the interior design may be impaired, it was considered to incorporate this lighting fixture into each heater.

FIG. 5 is a side end view showing an example of the above-mentioned integration proposal proposed by the present applicant. In the figure, A is a reflection case body which opens downward, and the total length is about 5 to 6 m. The bottom surface of the reflection case body A formed in this way has a three-sided structure of a flat surface B at the center and inclined surfaces C and C continuous diagonally above and to the left and right thereof. A heat radiation pipe D for gas is provided, and fluorescent lamps E for illumination are attached to the inside of the inclined surfaces C, C on both the left and right sides thereof. According to this, there is an advantage that far infrared rays for heating and light rays for illumination are applied to the lower side of the reflection case body A so that heating and illumination of a factory or a gymnasium can be performed at the same time.

[0005]

However, in the case of the lighting device integrated heater constructed as described above, the heat radiating pipe D, which is laid inside the central flat surface B, to the reflective case body A.
A part of the radiant heat radiated below the air flows along the left and right slopes C and C as indicated by the arrows Y and Y in the figure, and therefore receives the convection of the radiant heat. Slope C,
Since the fluorescent lamp E mounted on the inside of C immediately becomes dirty and the lighting effect is deteriorated, it is necessary to clean the fluorescent lamp E frequently, or the radiant heat causes the fluorescent lamp E to have a quick pain and a long life. There are various maintenance problems that are short, and improvement measures have been desired.

Therefore, a technical problem of the present invention is to prevent convection of radiant heat for heating in a ceiling-mounted far-infrared radiant heater in which lighting equipment is integrated. Another technical problem of the present invention is that the above-mentioned lighting equipment is integrated into a ceiling-mounted far-infrared radiant heater, and an air hose or electric cords hung separately on the ceiling surface of a factory is pulled out. It is to be able to store freely and be equipped with the function to perform various work efficiently.

[0007]

[Means for Solving the Problems] The measures taken by the present invention to solve the above technical problems are as follows. Inside the reflection case body opened downward, a heat radiation tube for combustion gas and a fluorescent lamp are arranged, and by irradiating the far infrared rays emitted from the heat radiation tube and the light beam of the fluorescent lamp downward, In a ceiling-mounted far-infrared radiant heater with a lighting function configured to simultaneously perform heating and lighting in a room, (1) The bottom surface of the reflection case body is continuously connected to a flat surface in the center and diagonally above and to the left and right It has a three-sided structure with an inclined surface, and a fluorescent lamp for illumination is attached to the inside of the central flat surface.
A heat radiation pipe for heating should be installed inside the left and right slopes. (2) Inside the reflective case, various hoses such as air hoses, power cords or switch cords and a reel around which electric cords are wound are attached, and the hose or electric cord wound around this reel is attached to the bottom of the reflective case. It should be configured so that it can be pulled out freely from the pull-out hole provided in.

[0008]

The above means operates as follows. In the element of (1) above, since the fluorescent lamp is mounted inside the central flat surface and the heat radiation tube is mounted inside the left and right inclined surfaces, radiant heat is convected to the left and right outside along the inclined surfaces. Since it does not flow in the direction of the central flat surface, it can protect the fluorescent lamp from radiant heat and prevent dirt and the like, while radiating radiant heat from the left and right sloping surfaces to the left and right in a wide range to enhance the heating effect To

In the element (2), various hoses such as an air hose, a power cord, or an electric cord for a light or a switch, or cords are wound around a reel and housed in a reflective case. This can be pulled out as needed to facilitate various operations efficiently, and since it is not necessary to pipe and wire various hoses and cords on the ceiling surface, the ceiling surface should be neatly organized and kept indoors. Allows you to keep the aesthetics of. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
