Embodiment 1

[0044] image 3 It is an enlarged sectional view of main parts of Example 1 of the showcase of the present invention. A translucent fluorescent lamp cover 10 covering the fluorescent lamp 9 is provided around the concave portion 6 . The fluorescent lamp cover 10 has a two-layer structure of an outer cover 13 and an inner cover 14 , and an insulating air layer 15 is formed between the outer cover 13 and the inner cover 14 .

[0045] At least a part (both ends) of the heat-insulating air layer 15 is formed in the recess 6 so that the recess 6 does not directly contact the showroom 11 . In the present embodiment, the front and rear end portions are formed in the concave portion 6 .

[0046] In addition, the thickness of the heat-insulating air layer 15 needs to be such that it has heat-insulating performance and does not cause convection in the heat-insulating air layer, and it is actually preferably about 2 mm to 8 mm.

[0047] With the above structure, the thermal insulation...

Embodiment 2

[0053] Figure 4 It is an enlarged cross-sectional view of the main part of Example 2 of the showcase of the present invention, and a light-transmitting fluorescent lamp cover 20 covering the fluorescent lamp 9 is provided around the concave portion 6 . The fluorescent lamp cover 20 has a two-layer structure of an outer cover 16 and an inner cover 14 , and a heat insulating air layer 15 is formed between the outer cover 16 and the inner cover 14 .

[0054] At least a part (both ends) of the heat-insulating air layer 15 is formed in the recess 6 so that the recess 6 does not directly contact the showroom 11 . In the present embodiment, the front and rear end portions are formed in the concave portion 6 .

[0055] In addition, the thickness of the heat-insulating air layer 15 needs to be such that it has heat-insulating performance and does not cause convection in the heat-insulating air layer, and it is actually preferably about 2 mm to 8 mm.

Embodiment 3

[0062] Figure 5 It is an enlarged cross-sectional view of the main part of Embodiment 3 of the showcase of the present invention. In addition to the structure of Embodiment 2, reflectors 17, 18.

[0063] With the above configuration, the light reflected by the reflecting plates 17 and 18 can be guided into the showroom 11 and the inside of the showroom 11 can be illuminated.

[0064] Moreover, since no reflection plate is provided on the back surface of the recessed part 6, the front lighting of the door 8 is suppressed.

Abstract

The invention provides a display case which inhibits the cooling of fluorescent lamps so as to inhibit illuminance decrease, flickering, etc. caused by temperature decrease. In the display case, heat insulation walls (2) having an opening (7) at the front form a display room (11). A part of the heat insulation walls form a concave part (6), in which a part of a fluorescent lamp (9) illuminating the inside of the display room is formed. In addition, fluorescent lampshades (10, 20) which cover the fluorescent lamp and have light transmission characteristics are arranged at the periphery of the concave part. The fluorescent lampshades have a double-layer structure of outer shades (13, 16) and an inner shade (14), and moreover a heat insulation air layer (15) is formed between the outer shades and the inner shade.

Description

technical field [0001] The present invention relates to a showcase which has a showroom with an open front formed in a heat insulating wall, and a fluorescent lamp is provided in the showroom so as to be able to illuminate the showroom. Background technique [0002] Such a conventional showcase is a showcase installed in a store such as a convenience store or a supermarket, and is provided with a fluorescent lamp for illuminating the showroom. [0003] Here, refer to Figure 6 The existing showcase 1 will be described. Figure 6 It is a main part sectional view showing a conventional showcase. This showcase is formed with a showroom 11 in which a front opening 7 is formed inside a heat insulating box (insulation wall) 2 as described above. The heat insulation box 2 includes an outer box 3 with an open front and an inner box 4 with an open front, and a heat insulating material 5 is foamed and filled between the outer box 3 and the inner box 4 . [0004] Moreover, the glass ...
