Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION Industrial Field of Application The present invention relates to a showcase equipped with a lighting device for indoor lighting.

2. Description of the Related Art In conventional showcases, the interior of the storage room is generally illuminated with a lighting device in order to make it easier to clearly see the items stored in the storage room from the outside. An example of this is disclosed in Publication No. 19669++. In this publication, a structure is adopted in which fluorescent lights are installed in the vertical direction on the inner surfaces of the refrigerator on both left and right walls constituted by heat insulating walls. Further, Japanese Utility Model Publication No. 60-9671 discloses a showcase in which a space is formed at the front end of a heat insulating wall, and illumination lights are arranged vertically within this space.

Problems to be Solved by the Invention In the above-mentioned former publication, the fluorescent lights themselves are attached to the inner surfaces of the refrigerator on both left and right walls, and are arranged at the top or front of the refrigerator to illuminate the interior of the refrigerator. A lighting room that stores lighting lights,
Instead of separating the parts of the left and right side walls where the fluorescent lamps are placed and communicating with the storage room, the electrical components that supply power to these fluorescent lamps are usually insulated below the storage room. Since it is often placed in a machine room divided by a wall, the wiring from the lighting room must be routed through the space on the back wall or through pillars installed at the four corners, It is necessary to form holes or notches in the edges of the wire, and this wiring work is very troublesome and has the problem of increasing the wiring distance.

On the other hand, in the latter publication, there is no separate installation problem when applied to a case where the side plate is composed of a heat insulating wall, but for a showcase with a transparent plate on the side, the transparent plate is Because it was thinner than the thickness of a lighting lamp, it could not be applied as is. In addition, since the transparent plate is installed at the showcase installation site, the lighting equipment installed vertically must also be installed at the same time.There is also the same problem as in the former publication, and both technologies require installation of the lighting equipment. It was hoped that the work would be simplified.

Therefore, the present invention provides a showcase that allows wiring work for lighting devices to be easily performed.
