Description

[Detailed explanation of the idea] [Technical field to which the idea belongs]

This invention relates to a lighting device for the interior of a hot and cold show case, which defines product storage chambers for a greenhouse and a refrigerator for storing cold products and hot products in the same case.

[Prior art and its problems]

As a storage case to accommodate the recent diversification of product types, the hot and cold storage case has multiple product storage rooms with different temperature atmospheres, such as a refrigerator room for storing cold products and a greenhouse room for storing hot products. Cold show cases have been put into practical use and are now on the market. In such a case, in order to enhance the product display effect by making the products stored inside the case clearly visible from the outside through the transparent door on the front, each product storage room is generally equipped with a fluorescent light to illuminate the inside of the case. It is deployed. In this case, a conventional structure is known in which fluorescent lamps are individually provided in each of the above-mentioned independent refrigerator compartments and greenhouse compartments. However, with this configuration in which fluorescent lights are installed in each room, the illuminance will vary between the lights installed in each room over time, and the brightness inside the refrigerator will also vary from the appearance. A situation occurs that makes you feel uncomfortable. Furthermore, in the case where fluorescent lights are installed in each room, lighting equipment is required for the number of lighting lights, which not only increases the equipment cost but also has the disadvantage that the power consumption associated with lighting is also large.

[Purpose of invention]

This idea was made in consideration of the above points, and it is a show case storage that eliminates the difficulties of the conventional lighting devices mentioned above, provides high lighting effects, and reduces equipment costs and power consumption. The purpose is to provide an interior lighting device.

[Key points of the idea]

In order to achieve the above object, this invention divides the inside of the warehouse with a partition wall to define a plurality of product storage chambers with mutually different temperature atmospheres, and also installs transparent doors in front of the plurality of product storage chambers. In the show case, a through hole is provided at the front edge of the partition wall and serves as a front open cutout hole, and the through hole extends through the through hole to the respective product storage chambers and is common to each chamber. It is constructed by deploying long fluorescent lights, and since the common fluorescent lights extend into each product storage room, each room can be brightly illuminated, and each room can be individually illuminated. Compared to the case where a dedicated fluorescent light is installed, since a common fluorescent light is installed in each room, the brightness of the fluorescent light can always be the same in each room, and the number of installed lighting equipment and power consumption can be reduced. Consumption can be reduced, and the fluorescent lamp can be replaced simply by opening the see-through door, moving the fluorescent lamp toward you, and pulling it out from the through hole.

[Example of idea]

1 to 3 show the structure of an embodiment of this invention, and first, the structure of the entire show case will be explained with reference to FIG. In the figure, 1 is the main case of the show case, and inside the case, there are a greenhouse compartment 3 for storing hot products and a refrigerator compartment 4 for storing cold products above and below the partition wall 2 placed in the center. Product display shelves 5 are provided in each of the rooms 2 and 3, and see-through doors 6 and 7 made of transparent glass are provided in the front of each room. Further, an electric heater 8 for warming products is installed in the hot storage room 3, and an evaporator 9 of a refrigerator and a fan 10 for circulating cold air are installed in the refrigerator room 4. In addition, 1
1 is a condensing unit of the refrigerator. Products stored in the greenhouse 3 with such a structure are heated by the heater 8.
The products heated by the refrigerator and stored in the refrigerator compartment 4 are cooled by the refrigerator. With this invention, for such a hot and cold storage case, the above-mentioned greenhouse chamber 3 and cold storage chamber 4 are
A fluorescent lamp 12 for illuminating the inside of the refrigerator common to each chamber is provided across both chambers. This fluorescent lamp 12 is a long fluorescent lamp that illuminates both chambers 3 and 4 at the same time. Through hole 13
It is installed vertically through the chamber and extends into both chambers 3 and 4. Furthermore, in the part that penetrates the partition wall, the gap between the fluorescent lamp 12 and the through hole 13 is filled with a heat insulating sealant 14 as shown in FIGS. This prevents heat convection from occurring between the storage chambers 3 and 4. In the embodiment shown in FIG. 2, the heat insulating sealing material 14 is 14
It is divided into two parts, front and back, divided into a, 14b4,
The divided sealing material on the front side is attached to the back side of the decorative board 15, and the decorative board 15 is configured to be fixed to the partition wall 2 from the front via fixing screws 16. On the other hand, in the embodiment shown in FIG.
A heat insulating sealing material 14 is installed in the through hole 13 by wrapping the fluorescent lamp 12 in a headband shape. To replace the fluorescent lamp 12, open the see-through door 6, loosen the screw 16 in the configuration shown in FIG. 2, and remove the decorative panel 15.
In the configuration shown in the figure, by moving the fluorescent lamps 12 for each heat-insulating sealing material 13 toward the front and pulling them out from the through holes 12, each can be easily performed from the front of the show case.

[Effect of the idea]

As described above, according to this invention, a through hole is provided at the front edge of the partition wall and serves as a front open cutout hole, and each of the through holes extending into each product storage chamber through the through hole is provided. By arranging a common long fluorescent light in each room, each product storage room defined in the warehouse can be brightly illuminated with the common fluorescent light, and each product storage room can be brightly illuminated. On the other hand, the brightness of the illumination light is always the same, and the products displayed in the refrigerator can be illuminated to make it easy to see them without giving an unnatural appearance. In addition, the number of installed lighting fixtures can be halved compared to the conventional configuration, and the power consumption of fluorescent lights can also be significantly reduced.Furthermore, when replacing fluorescent lights, open the see-through door and move the fluorescent lights to the front. Effects such as being able to perform the operation simply by pulling it out of the hole can also be obtained.
