Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerated showcase provided with a lighting device such as a fluorescent lamp for illuminating a storage room. 2. Description of the Related Art Conventionally, a refrigerated showcase of the so-called reach-in type has a front opening of a storage room covered with a heat insulating wall, which can be opened and closed by a glass door, and an opening of the storage room. A fluorescent lamp for illuminating the inside of the storage room is attached in a vertical direction inside the partition body that separates the sections. This fluorescent lamp is generally constructed by inserting a fluorescent tube into a light-transmitting tubular jacket and connecting sockets to both ends of the fluorescent tube, and the fluorescent tube is held at the center of the jacket by a spacer. The fluorescent lamp holds the side surface of the jacket with a curved clip fixed to the partition of the refrigerated showcase, and is held on the bottom surface by a non-slip fixed to the heat insulating wall inside the showcase storage room. Was something. According to the above structure, since the fluorescent lamp is installed in the refrigerated space in the storage room, the internal volume of the storage room is reduced. As a structure that does not reduce the internal volume of the storage room, there is a method of installing a fluorescent lamp by providing a recess in the partition body in the storage room. However, this causes an increase in processing cost and furthermore, the recess makes the heat insulating wall. Because the thickness decreases,
This caused the heat insulation performance to deteriorate. Also, in the above structure, the fluorescent lamp and the storage room air are in direct contact,
The temperature in the storage room being cooled was increased, and a load was applied to the refrigeration system. SUMMARY OF THE INVENTION [0004] The present invention has been made to solve the above-mentioned conventional technical problems, and relates to a lighting device for a refrigerated showcase. The present invention provides a refrigerated showcase that does not reduce the temperature and does not increase the temperature in the storage room. [0005] In order to achieve the above object, according to the present invention, a door provided with a multi-layer transparent plate is provided at an opening of a storage room so as to be openable and closable. In the refrigerated showcase, an illumination device for illuminating the inside of the storage room is provided between the multilayer transparent plates. According to the first aspect of the present invention, in a refrigerated showcase in which a door having a multi-layer transparent plate is provided at the opening of the storage room so as to be openable and closable, the storage room is interposed between the multi-layer transparent plates. By providing the lighting device for illuminating the storage room, the internal volume and the heat insulation performance of the storage room are not reduced, and the temperature of the storage room is not increased. An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a refrigerated showcase 1 of the embodiment. The refrigerated showcase of the embodiment is, for example, a low-temperature refrigerated or refrigerated showcase installed in a supermarket or a convenience store. The refrigerated showcase 1 is composed of a storage room 2 formed by a box-shaped heat insulating wall 4 and an opening 3 partitioned by a partition 7 provided on the front surface of the storage room 2. Has a door 11 attached by a hinge 5 provided in the storage room 2 so as to be freely opened and closed. In addition, storage room 2
A refrigerator machine room 6 including a compressor, a condenser, and the like forming part of a cooling device is provided above the cooling device, and a cooling device forming a part of a cooling device (not shown) is provided above the storage room 2. A blower is provided to cool the inside of the storage room 2 to a predetermined temperature.
Further, a plurality of shelves (not shown) are installed in the storage room 2 so that the shelves can be moved up and down so that the storage items are placed on the shelves and cooled and stored. As shown in FIGS. 2 to 5, a plurality of rotatable glass doors 11 provided in the front opening 3 in the storage room 2 are made of metal such as stainless steel on the outside, and open substantially in the center. And a frame member 14 into which a plurality of transparent plates such as glass 13 are fitted, and a heat insulating material 15 is provided between the outer plate 12 and the frame member 14. The handle 1 is attached to the outer plate 12.
6, a packing 17 having a built-in magnet at a location in contact with the storage room 2 on the storage room 2 side of the frame material 14,
The glass door 11 is in close contact with the storage room 2. Illumination devices such as fluorescent lamps 21 and 21 are mounted on the left and right sides of the double glass 13 of the glass door 11, respectively. The fluorescent lamp 21 includes a fluorescent tube 22 and sockets 23, 2 connected to upper and lower ends of the fluorescent tube 22 to supply power.
3, and lead wires 25, 25 are drawn out from the center of the outer surface of the sockets 23, 23. Socket 2
The clips 3 and 23 are held by a clip 26. The clip 26 is formed of a strip-shaped thin metal plate having elasticity, and is fixed to the frame member 14 with screws or the like and held. Further, the door 11 provided with the double glazing of the present invention
As shown in FIG. 4, a fluorescent lamp provided in a door 11 provided with double-glazing by extending the outer plate 12 at the center of the opening so as to reduce the width of the opening provided in the outer plate 12. 21
Is not visible from the outside of the storage room 2,
Since the width of the inner glass 11 is wider, the inside of the storage room 2 can be brightened. When the fluorescent lamp 21 is provided in the glass door 11 provided with the double-glazed glass 13, as shown in FIG.
4 is detachable at two places on the left and right with screws 27, 27, etc., so that the cover 18 is removed and the sockets 23, 23 fixed with clips 26, 26 are removed.
First, using the elasticity of the upper and lower clips 26, 26, first, while inserting the lower end of the fluorescent lamp 21 into the lower socket 23,
After slightly pressing down the gap between the upper and lower sockets 23, 23, the upper end of the fluorescent lamp 21 is inserted into the upper socket 23.
After the other fluorescent lamp 21 was provided in the same manner as described above, the cover 18 was put on the glass door 11 as shown by arrow C, and was fixed to the door 11 with screws 27, 27, and the lighting device was provided. The glass door has been completed. Since the cover 18 includes the heat insulating material 15 on the back surface of the outer plate 12, the heat insulating performance of the door 11 is not deteriorated. The cover 18 detachably provided on the frame member 14 of the door 11 may be provided on the side or under the door 11 other than above. If the fluorescent lamp 21 is provided in a tubular jacket via a spacer (not shown), the fluorescent lamp 21 will not be damaged by an external impact. Further, instead of the fluorescent lamp 21, any device using a light emitting diode or the like may be used as long as it is a lighting device for brightening the storage room. According to the present invention, since the fluorescent lamp 21 is separated from the atmosphere in the storage room 2 by the double glazing 13 by the above structure, the fluorescent lamp 21 does not come into direct contact with the cold air in the storage room 2 and the fluorescent lamp 21 It is possible to prevent the temperature inside the storage room 2 from rising due to the heat generated by the heat generation 21, and the cooling effect inside the storage room 2 is not reduced. Further, the heat generated by the fluorescent lamp 21 causes the double glass 13
This eliminates the need for a dew condensation prevention heater provided inside. Further, when changing from a cold storage provided with a door without the double-glazed glass 13 to a refrigerated showcase with a door provided with the double-glazed glass 13, a double-glazed display 21 incorporating the fluorescent lamp 21 of the present invention is used. By simply providing the layered glass door 11 in the opening 3 of the storage room 2, it is not necessary to specially provide a mounting member for the lighting device in the storage room, so that it can be simplified.
