Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, a refrigerator, a refrigerating showcase, etc., in which a machine room having a refrigerating device is formed in a lower portion of a main body thereof, and more particularly to a device for mounting a fluorescent ballast. .

[0002]

2. Description of the Related Art In a conventional refrigerated showcase, a glass door 2 is provided on the front surface of a main body 1 as shown in FIG.
A machine room 5 equipped with a refrigeration device 3 such as a refrigerant condenser and a control box 4 is formed below the main body 1, and the front surface of the machine room 5 is covered with a front panel 6 and side surfaces of the machine room 5. Is covered with a side panel 7, and a ballast 8 for a fluorescent lamp (not shown) attached to a display shelf, a ceiling or the like in the main body 1 is provided in the machine room 5
It was installed on the stand 9. However, on the mount 9,
Since a relatively large opening 10 is formed below the machine room 5 and communicates with the floor surface, when cleaning the floor surface of a store or the like where a refrigerated showcase is installed, water poured onto the floor surface by a hose or the like can be used. On the contrary, the ballast 8 and the wiring portion around it are likely to be caught from the opening 10, which may cause an unexpected failure of the ballast 8 and the wiring portion thereof.

As disclosed in Japanese Utility Model Laid-Open No. 2-41090, there is a refrigerating showcase in which a ballast for a lighting device is attached to a front inclined portion of a heat insulating wall of a case body. Since the surface temperature of the ballast rises considerably during lighting of the lighting device, the ballast mounted on the heat insulating wall of the case body has a relatively high temperature, which shortens the life of the ballast itself and / or its wiring. .

[0004]

DISCLOSURE OF THE INVENTION The present invention makes it difficult for a fluorescent lamp ballast and its wiring to fail in a refrigerating showcase in which a machine room having a refrigerating device is formed in a lower portion of a main body, and The purpose is to keep them at a relatively low temperature and prolong their life.

[0005]

Therefore, in the refrigerating showcase according to the present invention, a machine room having a refrigerating device is formed in the lower part of the main body, and a fluorescent lamp ballast is attached to the lower surface of the main body. The fluorescent lamp ballast is configured to be cooled by the cooling air of the refrigeration system.

[0006]

In other words, since the fluorescent ballast is attached to the bottom surface of the main body and is located relatively above the floor surface, the floor surface of the refrigerated showcase is not cleaned when cleaning the floor surface of a store or the like. Since the poured water does not splash on the fluorescent lamp ballast or the wiring part around it, the risk that they will break down is greatly reduced.In addition, the fluorescent ballast and the wiring part around it will not be cooled by the cooling air inside the machine room. As a result, the temperature of the fluorescent lamp is suppressed and the temperature rise thereof is surely suppressed, so that the life of the fluorescent lamp ballast and its wiring portion can be easily extended.

[0007]

Embodiments of the present invention will be described below by assigning the same reference numerals to the parts equivalent to those of the conventional device. 1 and 2, the refrigerating showcase 20 is composed of a main body 1 and a machine room 5 arranged below the main body 1, and a glass door 2 is attached to the front surface of the main body 1 while the inside of the machine room 5 is provided.
