For example, Japanese Patent Publication No. 6-78863 (F25D17 /
08) and the like. The structure near the door of the display room in such a showcase will be described with reference to FIG. FIG. 11 is a sectional view of the vicinity of a sliding door in a conventional showcase.

In FIG. 11, the display room 01 is cooled and has a lower temperature than the outside. This display room 0
The transparent glass door 02 is openably and closably closed at the opening of No. 1, and dew condensation may occur on the outside surface of the glass door 02. Then, the condensed water travels along the outer surface of the door 02 and drops onto the rail installation portion 03 on which the door 02 is slidably mounted, and the drainage water is slenderly arranged on the outer surface of the rail installation portion 03. It flows into the receiving portion 04 and is drained through this drainage receiving portion 04.

The display room 01 is illuminated by a fluorescent lamp (not shown). If the fluorescent lamp runs out of light,
You need to replace it with a new fluorescent lamp. Especially in the case of a face-to-face showcase, a special and long fluorescent lamp such as a T6 tube (slim tube) is used. Since this fluorescent lamp is special, it cannot be purchased immediately at an electronic store or the like, and it is necessary to place an order when purchasing, and it will be delivered about two weeks after the order is placed. In addition, when the fluorescent lamp is off, the display effect of the showcase is significantly reduced, so if the fluorescent lamp runs out, a spare fluorescent lamp can be replaced immediately in the store where the showcase is installed. It is stored in a warehouse, etc.

[0005]

By the way, since the above-mentioned drainage receiving portion 04 is formed substantially horizontally, it is difficult for the condensed water to flow, and the drainage receiving portion 04 easily collects. Therefore,
It is necessary to clean it from time to time, but the width m of the drainage receiving part 04 is 1
It was difficult to clean the drainage receiving part 04 because it was as narrow as 0 mm and the wall of the drainage receiving part 04 was formed substantially vertically.

A fluorescent lamp such as a T6 tube has a diameter of, for example, 20 mm and a length of 2400 mm, which is long and slender.
Since it is fragile, it is difficult to secure a storage place. If a spare fluorescent lamp is stored in a warehouse or the like, when the fluorescent lamp runs out, it is necessary to go to the warehouse or the like to pick up the spare fluorescent lamp. In addition, since various items other than fluorescent lamps are stored in the warehouse, it takes time and effort to find a spare fluorescent lamp. Furthermore, when various showcases are installed, there may be multiple types of fluorescent lamps. When a plurality of types of fluorescent lamps are stored in one place, it may be difficult to know which type of fluorescent lamp should be replaced.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a showcase in which maintenance such as cleaning and replacement of a fluorescent lamp is easy.
