Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a low-temperature showcase in which a cool air curtain is formed at an opening for taking out a product, and a night cover for the low-temperature showcase. . 2. Description of the Related Art A low-temperature showcase conventionally installed in a store such as a supermarket or a convenience store is disclosed, for example, in Japanese Utility Model Publication No. 61-19412 (F25D1).
As shown in (1/00), a cold air curtain is formed in the front opening to prevent outside air from entering through the opening. [0003] An automatic return type night cover is attached to the inside of the eave above the opening, and when the store is closed, the night cover is pulled out to cover the opening, thereby preventing unnecessary outflow of cool air from the opening. The power consumption was reduced. In a store such as a supermarket, as shown in FIG. 1, a plurality of low-temperature showcases 1A (open showcases) as shown in the above publication are arranged side by side, and a so-called round corner is provided at an end of the row. A low-temperature showcase 1B called a case is installed.
