Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerating open showcase which has a main body case having an approximately U-shaped cross section with an open top surface, and which forms the interior of the main body case, for illuminating the interior of the refrigerator The present invention relates to an internal lighting device.

[0002]

2. Description of the Related Art A refrigerating open showcase of this type is known as shown in FIG. In the figure, a case body 1 of a refrigerating open showcase has a substantially U-shaped cross-section with an open upper surface, and an inner box provided with an appropriate gap between the outer box 2 and a heat insulating wall. 3 to form an inside 4 inside the inner box 3. In addition, the gap forms a cool air circulation path 5, in which a fan 6 and a cooler 7 are arranged, and both ends of the cool air circulation path 5 face each other with the opening in between, and are provided with an air rectifier 8. The outlet 5a and the suction port 5b are formed. A decorative plate 9 is provided on the front surface of the upper end portion of the outer box 2 on the side of the air outlet 5a, and a fluorescent lamp 11 serving as an internal lighting device 10 is provided in front of the decorative plate 9 and The reflector 12 is installed.

In the refrigerated open showcase, products are stored and displayed in the compartment 4, and the air in the compartment is cooled by the fan 6 through the suction port 5b and the cooler 7, and the cooling air is blown out from the air outlet 5a. A cold air curtain 13 is formed in the opening to shut off the interior 4 from the outside air, and the product is cooled and kept cool. On the other hand, the merchandise is illuminated by the fluorescent lamp 11 so that the customer can easily see it, and the desired merchandise is taken out and sold by the customer.

[0004]

By the way, in the conventional refrigerating open showcase, the decorative plate 9 is cooled by the cooling air blown from the blowout port 5a to form dew on the surface thereof. There was a concern that the dew would make the customers wet their clothes and feel uncomfortable.
In order to eliminate this, a heater 14 is generally provided on the back surface of the decorative plate 9 to heat the decorative plate 9 to prevent dew condensation.

It is an object of the present invention to provide a refrigerator lighting device for a refrigerating open showcase, which does not cause dew condensation on a decorative plate without installing a heater and does not cause discomfort to customers.

[0006]

In order to achieve the above object, according to the present invention, an outer box and an inner box having a substantially U-shaped cross-section having an open upper surface are provided, and the outer box and the inner box are provided. The outlet of the outer box of the case body, in which the both ends of the case are opposed to each other to form a cool air circulation path forming an outlet and a suction port, and a decorative plate is provided at the outlet-side front end of the outer box. In the interior lighting device of a refrigerating open showcase, which is provided in front of the side front end face and includes a fluorescent lamp for illuminating the inside of the inner box, the fluorescent lamp is provided on the front end face of the outer box. And a decorative plate, and a reflecting plate for reflecting the light of the fluorescent lamp toward the inside of the storage is provided above the fluorescent lamp.

[0007]

The heat generated by the fluorescent lamp heats the decorative plate from its rear surface to prevent dew condensation. Further, the light of the fluorescent lamp is directed to the inside of the refrigerator by the reflecting plate to illuminate the product so that the customer can easily see it.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention, and the portions common to or the same as those in FIG. In FIG. 1, the decorative plate 9 is installed with an appropriate gap between it and the front end face of the outer box 2 on the outlet side, and the heater conventionally provided is omitted. In the interior lighting device 10, a fluorescent lamp 11 is arranged between the decorative plate 9 and the front end surface of the outer box 2, and above the fluorescent lamp 11, a substantially arcuate cross section is formed and one end of the decorative plate 9 is formed. A reflector 12 is provided so as to project upward from the front.

In the above structure, the decorative plate 9 is the fluorescent lamp 1.
It is heated from the back side by the heat generated by 1. Therefore, even if the cooling air from the outlet 5a is received, it is not cooled so much and dew is not generated on the surface. Further, the light of the fluorescent lamp 11 is reflected by the upper reflecting plate 12 and is directed to the inside 4 to illuminate the goods in the inside. Therefore, the customer does not have to worry about getting their clothes wet, and can easily identify the product and take out the desired product. On the other hand, the structure of the cooling open showcase is simplified by removing the heater, and the power consumption during operation can be saved.

[0010]

According to the present invention, an outer box and an inner box having an approximately U-shaped cross-section with an open upper surface are formed, and both ends of the outer box and the inner box are opposed to each other and an air outlet is formed. Provided in front of the air outlet side front end surface of the outer box of the case main body that forms a cold air circulation path forming a suction port and has a decorative plate at the air outlet side front end of the outer box, and inside the inner box In the interior lighting device of a refrigerating open showcase provided with a fluorescent lamp for illuminating the interior formed in one direction, the fluorescent lamp is disposed between the front end surface of the outer box and the decorative plate. Since a reflecting plate for reflecting the light of the fluorescent lamp toward the interior of the fluorescent lamp is provided above the fluorescent lamp, it is possible to prevent the dew condensation on the decorative plate and give the customer a feeling of discomfort. By removing the heater for heating, the configuration of the refrigerated showcase is easy and convenient. Enabling power saving in the can further customer in light brightly in a conventional similar box provides a storage room lighting apparatus that easily viewable products.
