Description

[Detailed Description of the Invention] The present invention relates to an improvement in the structure for attaching an auxiliary stand to the main body of a refrigerated/refrigerated open show case that closes the front opening for entering and exiting products with a cold air curtain.

Conventional frozen and refrigerated open storage cases are
As shown in the longitudinal sectional side view of the figure, a front edge plate 1d has an opening 6 for entering and exiting products on the front, and is provided with a top plate 1a, a back plate 1b, a bottom plate 1c, and a front decorative plate 1e.
A case body 1 is formed of a heat insulating wall 2, and a partition plate 3 is provided inside the case body 1 to divide it into a cold air circulation path 4 and a product storage 5.

In this way, during the case operation, the air sucked in by the blower 9 from the suction port 7 at the lower end of the cold air circulation path 4 is cooled by the cooler 10.
The cool air is blown out from the air outlet 8 at the upper end, forms a cold air curtain, closes the front opening 6, and keeps the inside of the product storage 5 cold.

By the way, when all the products cannot be displayed in the storage 5, the extension part 11b formed on the rear edge of the shelf 11a of the auxiliary stand 11 is extended over the upper surface of the front edge plate 1d. is erected in front of the front edge plate 1d, and products are displayed here as well.

However, if there are a particularly large amount of products to be sold, such as advertising products, they will be displayed not only on the shelf 11a but also from inside the storage compartment 5 to the extension part 11b, so there will be no gaps between these products. Edge plate 1
The suction port 7 formed behind d is blocked, and the circulation of the cold air flow is obstructed.As a result, a cold air curtain is not formed sufficiently, which may impair the cooling effect.

SUMMARY OF THE INVENTION An object of the present invention is to provide an open refrigerator/freezer case that eliminates the disadvantages of the conventional example and has a separate suction port on the auxiliary stand to ensure smooth circulation of cold air.

However, according to the present invention, the purpose of the lever is to form a cold air outlet above the front opening for loading and unloading products, a suction opening below, and close the opening with a cold air curtain. In this case, an auxiliary cold air inlet is formed at the front edge of an auxiliary stand for placing products attached to the front of the front edge plate of the case body, and the auxiliary cold air inlet is placed below the cold air outlet above the opening. This is achieved by providing a duct on the auxiliary stand that connects to the auxiliary cold air suction port, and opening the tip of this duct to the cold air circulation path below the suction port of the case body.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a longitudinal sectional side view showing an embodiment of the refrigerated/freezer open case of the present invention, in which the same components as those of the conventional example are given the same reference numerals.

In the figure, reference numeral 12 indicates an auxiliary stand attached to the front edge plate 1d of the case body 1.
2b is provided.

This mounting shelf 12b is hollow and consists of a bottom plate 12c and a mounting plate 12d, each having a rising portion 12e at its front edge. The other end is opened at the back of the shelf 12b, and the exhaust port 12h is connected thereto.
will be established.

In this state, the auxiliary suction port 12f is located below the cool air outlet 8 provided above the front opening 6 of the case body 1.

A connecting hole 13 is provided in the front edge plate 1d of the case body 1 at a position below the suction port 7 and closer to the suction port 7 than the blower 9 so as to communicate with the cold air circulation path 4.
The rear end of the storage shelf 12b is inserted here to communicate with the exhaust port 12h of the duct 12g.

In the figure, 12i is a stopper provided near the exhaust port 12h of the mounting shelf 12b.

Further, the front decorative plate 1e is made freely bendable by a hinge 14 or the like directly below the connecting hole 13, and furthermore, a closing plate 15 is provided behind the connecting hole 13.

Next, the usage and effect will be explained.

Tilt the front decorative panel 1e downward to open the connecting hole 13, and insert the rear end of the shelf 12b of the auxiliary stand 12 into the connecting hole 13 until the stopper 12i hits the front edge plate 1d. A stand 12 is attached to the show case body 1, and products are displayed here.

In this state, the closing plate 15 is pushed up by the rear end of the mounting shelf 12b, and the duct 12g communicates with the cold air circulation path 4.

The cold air blown out from the air outlet 8 is sucked into the auxiliary suction port 12f of the auxiliary stand 12, forms a cold air curtain between them, and flows over the front opening 6 of the case body 1 and the mounting shelf 12b of the auxiliary stand 12. It is closed to keep the inside of the warehouse 5 and the top of the shelf 12b cool.

The cold air sucked from the auxiliary suction port 12f passes through the duct 12g and enters the cold air circulation path 4 of the case body 1.
The air is guided into the air, cooled by the cooler 10, and then blown out from the air outlet 8 again.

In this way, even if the suction port 7 on the side of the auxiliary case body 1 is blocked by a product, cold air will still flow through the auxiliary suction port 12.
Since the cold air is sucked in from f, the circulation of cold air is performed smoothly, and the products are kept cool.

When the auxiliary stand 12 is removed, the closing plate 15 hangs down under its own weight and closes the connecting hole 13 from the inside, and the front decorative panel 1e is flipped up to hide the connecting hole 13 from the outside, thereby preventing cold air from leaking to the outside. It can be completely prevented, and it also has a good appearance.

As described above, the refrigerated open storage case of the present invention has a cold air outlet formed above the front opening for loading and unloading products, and a suction port formed below, and the opening is closed with a cold air curtain. In a refrigerated open case, an auxiliary cold air inlet is formed at the front edge of an auxiliary stand for placing products attached to the front of the front edge plate of the case body, and the auxiliary cold air inlet is used to draw cold air above the opening. A duct located below the outlet and connected to the auxiliary cold air intake is installed on the auxiliary stand, and the tip of this duct is opened to the cold air circulation path below the intake of the case body, so it can be used for advertising products and display products. Even if the intake port on the side of the case body is blocked by a large amount of these products, the circulation of cold air will not be hindered because the cold air will be sucked in from the auxiliary intake port provided separately on the auxiliary stand. Without,
The inside of the refrigerator is well kept cold.
