A handle 14 for opening and closing the heat insulating door 8 is attached to the outside of the latch body 11.

Next, the ceiling panel 4 will be described in detail with reference to FIGS. The ceiling panel 4 includes an inner plate 15 and an outer plate 16 disposed at predetermined intervals, a frame member 17 disposed at a peripheral portion of the inner plate 15 and the outer plate 16, an inner plate 15, and an outer plate 15. A foaming heat insulating material 18 such as foamed polyurethane filled in a space formed by the plate 16 and the frame material 17.
It is composed of

The frame member 17 serves as a connecting portion when connecting the ceiling panels 4 and 4 to each other. The frame member 17 includes a member having a convex portion 17A and a member having a concave portion 17B. Have one set each.
Then, the projections 17A of one panel are fitted into the depressions 17B of the adjacent panel, and the two ceiling panels 4, 4 are integrated.

Then, the inside of the convex portion 17A and the concave portion 17B
Inside, is disposed a not-shown coupling (referred to as a pair of a hook body having a hook and a pin body having a pin), which is called a rotary lock. By rotating the hooks of the hook body and connecting them to the pins of the pin body, both are firmly locked, and the panels are firmly connected and fixed by a simple operation.

Here, the ceiling panel 4 includes a ceiling panel 4A provided with a lighting device as shown in FIG. In the ceiling panel 4A, a concave portion 19 is formed on the inner plate 15 side. In the concave portion 19, a surface of the flat fluorescent lamp 20 on the storage room side to which a wiring connection (not shown) is made is formed on the ceiling panel 4A.
And is buried so as to be substantially flush with the surface of.

Further, discharge electrodes 44, 44 are disposed on a pair of opposing side surfaces in the glass container.
4 and 44 are connected to electrode leads (not shown). Further, the inside of the glass container is made substantially vacuum, and a small amount of mercury vapor (Hg) or a small amount of a rare gas such as argon (Ar) is sealed therein.

Then, an AC power supply is connected to the electrode lead through a wiring (not shown), and a discharge is caused between the discharge electrodes 44, 44. When the accelerated electrons 46 collide with mercury (Hg) or argon (Ar) molecules, The energy level changes from the ground state to the excited state. When the excited molecules or atoms return to the ground state, ultraviolet rays peculiar to each molecule are emitted, and when the ultraviolet rays hit the phosphors 43, 43, they are emitted from the surface of the plate glass 42 as visible light. Thereby, for example, a predetermined illuminance of milky white can be obtained from the surface of the flat fluorescent lamp 20.

The flat fluorescent lamp 20 emits ultraviolet rays radiated from each molecule into the storage chamber 10 as it is by omitting the phosphor 43 disposed inside the glass container on a part or the whole surface. Is also good. Thereby, it becomes possible to sterilize the stored matter stored in the storage room 10.

Furthermore, since the flat fluorescent lamp 20 attached to the ceiling panel 4A has a small width, an illumination device can be attached without substantially reducing the thickness of the heat insulating material 18. For this reason, the thickness of the heat insulating material 18 can be sufficiently ensured, and the heat insulating effect can be improved. Furthermore, since the inside of the flat-type fluorescent lamp 20 is configured in a substantially vacuum state, the heat-insulating effect can be exhibited by the flat-type fluorescent lamp 20 itself.

Further, even when a storage object is stored in the immediate vicinity of the flat fluorescent lamp 20, the flat fluorescent lamp 20 does not hinder the storage of the storage object. Furthermore, since the flat fluorescent lamp 20 and the ceiling panel 4A are formed substantially flush with each other, the adhesion of dust and the like is reduced, and the hygiene is also excellent. In addition, since the flat fluorescent lamp 20 does not generate a heat load, it is possible to avoid a problem that causes deterioration of product quality without heating the stored material.

On the other hand, the floor panel 5 will be described with reference to FIGS. The floor panel 5 is configured substantially in the same manner as the ceiling panel 4. For example, a recess (not shown) is formed in the floor panel 5 </ b> A configuring the passage position of the storage room 10 as described above. In the recess, the surface of the flat fluorescent lamp 21 similar to the flat fluorescent lamp 20 is buried so as to be substantially flush with the surface of the floor panel 5A or the like. In addition, a flat fluorescent lamp may be provided at a position serving as a guide for the storage position of the storage object to position the storage room.

Thus, in addition to the effect of the ceiling panel 4A, illumination can be performed from below, so that even when the stored items are stacked high left and right as shown in FIG. You can work safely. Further, even when the worker is locked in the storage room 10, the worker can be safely guided to the position of the heat insulating door 8 by the flat fluorescent lamp 21 embedded in the floor panel 5A.

Since the flat fluorescent lamp 21 is buried in the floor panel 5A or the like, the illuminance is lower than that in the case where the fluorescent lamp is used to indicate the passage position or the storage position of the storage as in the conventional case. Because it is extremely high, it can be easily recognized. Further, since there is no problem of peeling as in the case of the fluorescent seal, the position can be always displayed.

Furthermore, since the flat fluorescent lamp 21 is buried substantially flush with the floor panel 5A, it is possible to avoid the danger of the worker tripping over irregularities and the like, and to improve safety. .
