The installation structure of a tabletop refrigerated showcase.

2. Description of the Related Art This type of refrigerated showcase is usually composed of an upper storage room and a lower machine room, and various proposals regarding this have been made. Among them, for example, Jikkou 61-25578
In the publication, a meandering cooler is easily attached to the upper part of the storage chamber.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the publications cited in the above-mentioned prior art, as its basic structure, a storage room is formed in the upper part and a machine room is formed in the lower part, and A cooler is provided, and a compressor and a condenser are provided in the machine room. As the name suggests, the small refrigerated showcases of the refrigerated showcases are used while being placed on the tabletop, and the compressor and the condenser are arranged below them. Therefore, a considerable weight is added to the top plate of the table on which the showcase is placed. For this reason, when the table top is used for a long period of time, the weight of the showcase may cause the table top plate to warp or crack or crack. In addition, it was necessary to pay particular attention when placing it on a display case that is frequently used in pharmacies and discount stores. Because the top plate of the display case is generally made of glass in order to improve the display effect, and this is inferior in strength to the top plate of a normal table, so the influence on the top plate becomes larger. It is necessary to take special measures for the display case, such as increasing the thickness of the top glass or using glass with improved strength, and there are many restrictions when using the tabletop showcase. At the same time, there was a problem that it was necessary to perform very troublesome work. If the storage space is made wider and the compressor is stored in the showcase body, the total height of the showcase will inevitably increase. It also included a problem from another perspective of hindering the face-to-face sales work.

Therefore, the present invention provides a tabletop refrigerating showcase in which the body of the refrigerating showcase is separated into two, one is a storage room and the other is a machine room, and both are connected by a pipe for circulating cold air. .
