Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Application Field The present invention relates to a forced convection type cooling showcase that blows cold air into a product storage section to cool the product storage section. Concerning improvements to exhibition stands.

Conventional showcases equipped with cooling mechanisms are generally divided into two types: direct cooling type and cold air forced circulation type. If the products are stored all at once in the product storage section, there will be no gaps between the products, which will obstruct the natural convection or forced convection of cold air and reduce cooling efficiency. It is necessary to arrange them in an orderly manner while maintaining the spacing. However, arranging products in an orderly manner while maintaining intervals is a very troublesome and troublesome task, and it takes time to replenish and fill the products. Therefore, in order to organize the products, the section structure was developed as a showcase equipped with some kind of arrangement means such as partitions.
18290 has been proposed.

Problems to be Solved by the Invention In the above-mentioned publication, in order to facilitate the positioning of each product in a tiered open case, each shelf is individually sectioned. They are arranged with certain spacing between them. However, since this example targets direct cooling method cooling,
The structure does not take into account cold air passage for natural convection and forced convection, and cold air cannot pass between products. For this reason, cooling is performed for each section that has been individually formed, and it is difficult to cool the entire showcase uniformly, resulting in a problem that the temperature distribution within the showcase tends to be uneven.

Therefore, the present invention aims to provide a cooling showcase equipped with a display stand that not only separates products into individual sections but also effectively utilizes the area formed by the partitions where products cannot be placed to circulate cold air. This is an issue to be addressed.

[Structure of the invention]

Means for Solving the Problems The present invention provides a cooling showcase in which a space between a transparent member having a central portion as a top and a display stand having a central portion as a top serves as a product storage portion. , the display stand includes a plurality of circular recesses arranged side by side to individually receive the lower part of the product, a plurality of square recesses that individually receive the lower part of the product, and a suction port formed on the outer periphery of both recesses. , the shape and shape of the remaining part between the part where the circular recess is formed and the part where the square recess is formed.
The air outlet is provided with air outlets that are formed with appropriately different sizes and number of air outlets.

Product cannot be placed in the surplus area between the part where the circular recess is formed and the part where the rectangular recess is formed due to the difference in shape of the recess, but this surplus area can be used to open the air outlet. Because of this, the cold air blown out passes through the gaps between the products, making it easier for the cold air to come into contact with the products.

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 6.

(1) is a closed display box (12) with a product storage area (12).

The ventilation room (13) is a high-pressure space that introduces air (this is called cold air) that has been cooled in the machine box and is conveyed through the ventilation pipe, and guides this cold air to the product storage section (12). A supply section (16) and a cold air return section (17) as a low-pressure space that collects air after cooling the product storage section (12) (this is referred to as return cold air) and guides it to the blast pipe. are formed into separate sections.

To explain an example of this ventilation chamber (13), the cold air supply section (
16), the cold air introduced from the cold air inlet (42) provided on the - side is sequentially rotated to the center part, and is applied to the bottom surface of the turntable (18) through the 1:1 opening (40) formed at the center of the top surface. The first standing wall (48A
) and a second vertical wall (48B) are installed on the bottom partition (47), and a partial opening (40
) is installed. Note that this upper plate has an opening (
An annular stepped portion (41) is eccentrically formed around the turntable (18) so that the turntable (18) can be positioned in correspondence with an annular vertical wall (66) on the lower surface of the turntable (18), which will be described later. I have to. Here the cold air inlet (42)
The cold air introduced from the opening (40) is directed along the second vertical wall (48B), moves to the center while sequentially turning along the first vertical wall (48A), and hits the turntable (18) located above from the opening (40). ), and is blown out into the product storage section (12) from an air outlet (58) formed on the turntable (18), which will be described later.

Containers (hereinafter referred to as beverage containers) (43) filled with sales products such as medicinal solutions and soft drinks are placed on the turntable (18) located at the bottom of the product storage section (12). When the beverage containers (43) are placed, a product partitioning function is provided to ensure that there is a gap between the beverage containers (43), and it is confirmed from the outside that the beverage containers (43) are lined up. The height of the bottom receiving part is set at different heights so that it can function as a shelf.

That is, the turntable (18) is formed to have a circular shape in plan view, and a spherical shape (more specifically, a curved surface of a part of a sphere) in side view, with the center being highest and decreasing in order from the center to the periphery. , is rotatably held by a rotation auxiliary member (70) held in two different configurations.

In addition, this turntable (18) has a plurality of recesses (54) arranged in an orderly manner, each having a shape (for example, a circle or a rectangle) in plan view that approximately matches the bottom shape of the products to be displayed, for product partitioning. Set it up. In this example, 24 circular recesses (55) are arranged on the outside and 12 circular recesses (55) on the inside thereof, and the inner circular recess (55B) has a higher bottom surface than the outer circular recess (55A). The bottom surface of the circular recess (55) has a height of 1.5 to 2 mm.
A small tapered projection (57) having a height of about 511n is formed. Furthermore, in the six examples in which ten rectangular recesses (56) are formed inside, eight small recesses (56A) and two large recesses (56B) are provided as the rectangular recesses (56). ing. The remainder of the double recesses (56A) (56B>) is a so-called dead space, such as a rectangular recess (56B).

〔Effect of the invention〕

As detailed above, according to the present invention, it is possible to organize and display products with circular bottom shapes and square bottom shapes separately on a display stand, and also to display products with a circular bottom shape and a rectangular bottom shape separately. A gap can be reliably formed. Since the air outlet is formed in the excess space (so-called dead space where products are not placed) that is inevitably created by forming the circular recess and the square recess, the surface of the display table can be used effectively. In addition to this, cold air can be blown out from the gaps between products, making it easier for the cold air to come into contact with the products, improving cooling efficiency. In addition, the air outlet and suction port are not blocked by the products on display, and cool air convection can occur smoothly.
