As a supplier, the
There is Publication No. 8.

Problems to be Solved by the Invention The publications listed in the above-mentioned prior art are directed to a so-called oven-type showcase that has a front opening as a showcase section. Various measures are taken to prevent heat from entering the product storage area, and in order to apply these measures to closed-type showcases, improvements must be made to the structure of the product storage area, product confirmation, and lighting. There are too many structural differences such as the arrangement of devices, and the advantages of a separate type cannot be fully exploited, making it unsuitable for application to closed type showcases. Also, for insulated ducts,
It does not have a special configuration for wiring for electrical connection, and its length cannot be adjusted easily and reliably.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a closed-type separate showcase that improves the efficiency of wiring work when connecting ducts and allows the length of the ducts to be adjusted according to the height of the display stand. The task is to

[Structure of the invention]

Means for Solving the Problems The showcase of the present invention includes a machine box for storing mechanical parts and for cooling and discharging air, and a ventilation box for supplying and collecting air into the storage room, with a product storage chamber disposed in the upper part. A display box with a lighting room and a lighting device installed at the bottom and placed on a display stand, and a blower pipe that connects both boxes so that air can circulate through an outbound tube and a return tube and is covered with a heat insulating material. The air pipe consists of a hanging piece that is attached to the display stand on the upper part, and a long spacer for length adjustment that is connected to the lower end of the air pipe depending on the height of the display stand on the lower part. A spacer selection means for determining the spacer is provided.

Function When the hanging piece installed at the top of the blower pipe is hung on the top surface of the display stand to form a blower pipe, the height from the floor to the lower end of the blower pipe changes depending on the height of the display stand. Accordingly, the upper end of the machine box holder, which has a certain height, determines the value shown on the adjustment scale provided at the bottom of the blower pipe, and the hanging piece is used not only for positioning and stable installation of the blower pipe. Together with the adjustment scale, it acts as a selection member for determining the length (thickness) of the spacer. The adjustment scale also functions as a height measuring means for determining the approximate height of the display stand when the showcase is installed on the display stand.
