Description

The present invention relates to a forced convection type cooling showcase in which cold air is blown and cooled in a product storage unit. More specifically, the product is displayed and mounted. Regarding the improvement of the exhibition stand.

2. Description of the Related Art Showcases equipped with a cooling mechanism are generally roughly classified into two types, a direct cooling type and a cold air forced circulation type. When products are stored in the full product storage section, there is no gap between the products, and the products hinder the natural convection or forced convection of the cool air, reducing the cooling efficiency. It is necessary to arrange them neatly while holding them. However, orderly arranging the products while maintaining the intervals is a very troublesome and troublesome work, and it takes time to replenish and fill the products.
Then, as a showcase provided with some sort of arrangement means such as compartments or partitions for organizing products, Jikkō Sho 42-1
Japanese Patent No. 8290 has been proposed.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above publication, in order to facilitate the positioning of each product in a shelf-type oven case, each shelf is individually partitioned and formed. They are arranged with certain intervals. However, since this example is intended for direct cooling,
The configuration does not take into consideration the passage of cold air for natural convection and forced convection of cold air, and cold air cannot pass between products. For this reason, cooling is performed for each of the compartments that are individually formed, and uniform cooling as a whole is difficult, and there is a problem that the temperature distribution in the showcase tends to be biased.

In view of the above, the present invention provides a cooling showcase including a display stand that effectively uses, in addition to compartmentalizing the products individually, a portion formed by the compartments on which the products cannot be placed for cold air distribution. This is an issue.

[Structure of Invention]

Means for Solving the Problems The present invention provides a cooling showcase in which a space between a see-through member having a central portion as a top and an exhibition stand having a central portion as a top serves as a product storage unit.
