[0004]

This type of showcase is installed not only in supermarkets and convenience stores but also in coffee shops and the like. By the way, since the inside of the store is bright in the supermarket, etc., generally, the brighter the inside of the store, the more the display and sales effect of the products is improved. However, in a coffee shop or the like, the inside of the shop is not as bright as a supermarket, and is illuminated relatively darkly to give an atmosphere. If the interior of the showcase is illuminated brightly in such an environment, there is a risk of destroying the atmosphere in the store. However, in the configuration as described in the above publication, if a portion other than the reflection film is directed toward the interior, it is too bright and When facing the inside of the store, it is no longer possible to illuminate the inside of the store, so it is difficult to install in stores with such an atmosphere, and in order to solve that, it is necessary to perform dimming control of the fluorescent lamp itself. There was a problem that became.

Further, particularly when the product to be displayed is food, there is a problem that if the product is illuminated excessively brightly, discoloration or fading of the food will occur, reducing the commercial value, and the color of the illumination that makes the food color look delicious. , Depending on the type of food,
Conventionally, therefore, every time the food to be displayed is changed, it is used by being replaced with a coating of a different color, which causes a problem that the replacement of the coating becomes complicated.

The present invention has been made to solve the conventional problems, and an object of the present invention is to provide a showcase capable of appropriately illuminating an exhibition room in accordance with the environment in which it is used and the state of use. And

[0007]

That is, the showcase 1 of the present invention comprises an exhibition room 2, a fluorescent lamp 8 for illuminating the inside of the exhibition room 2, and a cylinder provided around the fluorescent lamp 8. And a translucent covering body 17 in the shape of a circle, the translucent covering body 17 is rotatably provided with the longitudinal direction of the fluorescent lamp 8 as a rotation axis, and the fluorescent lamp in its radial direction as a whole. 8 is allowed, and the portions having different light transmittances or different wavelengths of the transmitted light (transparent portion 17A, semi-transparent portion 17B, reddish color portion 2) with the longitudinal direction as a boundary.
3, a bluish color portion 24) is provided.

[0008]

According to the showcase 1 of the present invention, the illumination of the exhibition room 2 can be changed only by rotating the translucent cover 17 according to the environment in which it is installed and the situation of use.
That is, when installing in a bright store such as a supermarket, the exhibition room 2 can be illuminated brightly by arranging the portion (transparent portion) 17A having a high light transmittance toward the exhibition room 2 side, and lighting of a coffee shop or the like. When installed in a dark store, the light intensity of the exhibition room 2 can be reduced and the atmosphere of the shop can be adjusted by directing the portion (semi-transparent portion) 17B having low light transmittance toward the exhibition room 2 side. ..

When food is displayed in the showcase 1, red-colored illumination is suitable for making meat look delicious, and bluish-colored illumination is suitable for making fresh fish look delicious. Therefore, the translucent cover 17 should be color-coded into a portion (red-based color portion) 23 that transmits light of a red frequency and a portion (blue-based color portion) 24 that transmits light of a blue frequency. Therefore, even if the displayed food is changed between meat and fresh fish,
Only by rotating the translucent cover 17, it is possible to deal with the change of these food types.

Embodiments of the present invention will now be described with reference to the drawings. 1 is a perspective view of a fluorescent lamp 8 of a low temperature showcase 1 according to an embodiment of the present invention, FIG. 2 is a perspective view of the low temperature showcase 1, and FIG. 3 is a sectional view taken along the line AA of FIG. .. The product display room 2 of the low-temperature showcase 1 includes transparent paired glass transparent walls 5 and 5 supported by front columns 3 and 3 and rear columns 4 and 4 standing upright at four corners, a top wall 6 and a front surface. And a transparent door 7. Fluorescent lamps 8 are vertically mounted inside the front columns 3 and 3, and a plurality of shelves 9 are installed in the exhibition room 2.

Further, in the lower part of the exhibition room 2, a container-shaped heat insulating material (not shown) opened upward is provided, and a cooler and a cool air circulation blower (not shown) are provided therein. A bottom frame 11 is attached to the upper end of the heat insulating material, and a cold air discharge port 12 and a cold air suction port 13 located in the exhibition room 2 are formed in the bottom frame 11 and both
A bottom plate 14 is installed between 2 and 13. The cool air cooled by the cooler is blown out from the cool air discharge port 12 into the exhibition room 2 by the cool air circulation blower, circulates inside, and is sucked in through the cool air suction port 13. As a result, the interior of the exhibition room 2 is cooled to a predetermined refrigerating temperature, and is used for cooling and displaying foods such as fruits and vegetables, meat and fresh fish, and beverages such as wine.

Next, in FIG. 1, the fluorescent lamp 8 is connected at its upper and lower ends to fluorescent lamp sockets 16 and 16, and further,
Around the fluorescent lamp 8 is provided a cylindrical translucent covering body 17 formed by extrusion molding of a polycarbonate resin. The covering 17 is a light-transmitting material that allows light to pass through in the radial direction as a whole, but by changing the color density of the resin material, half of the covering 17 with the longitudinal direction as a boundary line is formed. The transparent portion 17A having a large light transmittance is formed, and the other half is formed as a semi-transparent portion 17B having a small light transmittance. Further, the cover 17 is rotatably inserted between the upper and lower fluorescent lamp sockets 16 and 16 with the longitudinal direction of the fluorescent lamp 8 as a rotation axis, and the fluorescent lamp 8 is displayed by being substantially sealed from the outside. The fluorescent lamp 8 is insulated from the cold air in the chamber 2.

As shown in the sectional view of FIG. 3, the front support column 3 is composed of a support column body 3A having a semi-arcuate holding portion 19 and a support column cover 3B attached to the outer surface of the support column body 3A. There is. The inner surface of the holding portion 19 of the front support column 3 matches the outer peripheral surface of the covering body 17 of the fluorescent lamp 8, and the fluorescent lamp 8 provided with such a covering body 17 is inserted into the holding portion 19 and It is attached to the exhibition room 2 side. Further, at this time, the cover 17 is rotatable in the holding portion 19.

In such a structure, when the low temperature showcase 1 is installed in a bright store such as a supermarket, the transparent portion 17A of the cover 17 is located on the exhibition room 2 side as shown in FIG. As a result, most of the light emitted from the fluorescent lamp 8 in the direction of the exhibition room 2 passes through the cover 17 as indicated by the large arrow in FIG. 3, so that the interior of the exhibition room 2 can be illuminated brightly. Therefore, the product on the net rack 9 in the exhibition room 2 can be illuminated brightly, and the appeal effect of the product can be improved.

On the other hand, when the low temperature showcase 1 is installed in a coffee shop or other store with relatively dark lighting, the cover 17 is rotated counterclockwise 180 degrees from the state shown in FIG. The semi-transparent part 17B of 17 is located on the exhibition room 2 side. As a result, the transmission of light from the fluorescent lamp 8 is restricted by the covering 17 as indicated by the small arrow in FIG. 4, so the illuminance in the exhibition room 2 is reduced and the brightness is adjusted to the atmosphere in the store. It can be

Further, from the state shown in FIG. 4, the cover 17 is further rotated counterclockwise by about 100 degrees, and as shown in FIG.
The semi-transparent part 17 is a part of the front side of the exhibition room 2 side of 7
If the remaining part on the side of the exhibition room 2 becomes the transparent portion 17A, the interior of the exhibition room 2 is illuminated brightly as shown by the large arrow in the figure, and the light directed toward the door 7 is the small arrow in the figure. It is also possible to limit the fluorescent lamp 8 from the outside of the door 7 so that it is not dazzled, as shown in FIG.

FIG. 6 shows a perspective view of a fluorescent lamp 8 equipped with a cover 17 of another embodiment. In this case as well, the covering 17 is transparent as a whole, but by changing the color tone of the resin material, the half with the longitudinal direction as the boundary line is the reddish color portion 23, and the other half is the bluish color. The part 24 is formed. Further, at one of the boundary lines of the cover 17, a handle 2 extending in the longitudinal direction and slightly protruding in the radial direction is provided.
5 is integrally formed. The fluorescent lamp 8 has a covering 1
The handle 25 of No. 7 is arranged on a portion of the holding portion 19 of the front support column 3 having no wall surface and attached to the front support column 3.

In such a structure, for example, when the meat is displayed in the exhibition room 2, the reddish color portion 23 is arranged on the side of the exhibition room 2 so that the meat is illuminated with light of a reddish color tone. Therefore, it is possible to make the meat look delicious to the customer.
Also, when displaying fresh fish in exhibition room 2, handle 25
If the cover 17 is rotated so that the bluish color portion 24 is on the side of the exhibition room 2, the fresh fish is illuminated by the light of a bluish color tone, so that the fresh fish can be similarly tasted to the customer. You can

As described above, according to the covering body 17 of the embodiment shown in FIG. 6, even if the kind of the product in the exhibition room 2 is changed, the color of the illumination can be changed only by rotating it. As described above, it is possible to omit the trouble of changing the cover 17 and the like, and it is possible to very easily respond to the change of the displayed product and improve the lighting effect of the product. Moreover, since the cover 17 is provided with the handle 25, the rotating operation of the cover 17 can be performed very smoothly.

Although the present invention is applied to a low temperature showcase surrounded by a transparent wall in the embodiments, the present invention is not limited to this and is also effective when applied to a general open showcase.

[0021]

As described above in detail, according to the present invention, it is possible to illuminate the interior of the exhibition room in accordance with the environment in which the showcase is installed and the situation of use. It can be significantly improved. In particular, since the change of the lighting effect can be realized only by rotating the translucent cover, the operability is extremely good, and the interior of the exhibition room has a simple structure without dimming control of the fluorescent lamp. Since the illuminance can be adjusted, the manufacturing cost can be improved.
