  The present invention relates to a cold air circulation type open showcase that is installed and used at a store in a store, and more particularly to a structure of a merchandise display shelf arranged in a warehouse.

  As the cold air circulation open showcase mentioned above, product display shelves arranged in the upper and lower stages are placed in the open front case body, and from the cold air outlet located on the ceiling of the case body to the suction port at the bottom of the warehouse An open showcase is known in which a cold air curtain is blown out and formed in the front area of the interior of the cabinet to keep the interior cool (see, for example, Patent Document 1).

  In the above open showcase, in order to prevent the product display shelf from unnecessarily interfering with the cool air curtain that blows out to the front area of the cabinet and disturbing the laminar flow of the air curtain, the product display shelf is The curtain is installed away from the airflow, but with such a configuration, there is a problem that the storage efficiency of the displayed product is lowered due to the restriction of the depth dimension of the product display shelf.

  Therefore, in order to expand the depth of the merchandise display shelf forward without disturbing the laminar flow of the cool air curtain, the inventors have increased the capacity of the merchandise to increase the number of products accommodated. Proposed a product display shelf with an air curtain wind guide mechanism that allows the shelf of the product display shelf to be expanded to near the front of the case body, and then the product display shelf. 5 and 6 show the structure of an open showcase equipped with a product display shelf and a product display shelf.

  In FIG. 5, reference numeral 1 denotes an open front case body that becomes a heat-insulating housing similar to that of Patent Document 1, 2 denotes an interior partition wall, and 3 denotes cold air defined between the case body 1 and the interior partition wall 2. A circulation duct 3a is connected to the cold air circulation duct 3 and is arranged in the front part of the ceiling of the case body 1. The honeycomb rectification type cold air outlet 3b is opposed to the cold air outlet 3a and is opened at the bottom side front part of the case body 1. 4 is a cooler (evaporator of the refrigerator) disposed at the bottom (ship bottom) of the case body 1, 5 is a cold-circulation fan, 6 is a deck pan at the bottom of the cabinet, 7 is arranged vertically in the case body 1 The product display shelf 7 is installed on shelf columns (not shown) standing on the front surface of the rear panel of the internal partition wall 2 via shelf brackets 8.

  With the above configuration, the cold air that has flowed through the cooler 4 flows through the cold air circulation duct 3 as shown by the arrow in the cool operation of the showcase, and the front side of the case body 1 in the interior of the case body 1 from the cold air outlet 3a toward the suction port 3b. It is well known that the cold air curtain 9 is blown out obliquely downward in the area, and the cold air flow 10 is blown out from the punching hole drilled in the rear panel surface of the internal partition wall 2 into the interior to keep the interior cool. It is. In addition, 11 is a product placed on the product display shelf 7, and 12 is an illuminating lamp (straight tube fluorescent lamp) arranged on the lower surface of the product display shelf 7.

  Next, the structure of the commodity display shelf 7 is shown in FIG. That is, a wind guide plate 7b is provided in the width direction of the shelf plate 7a via a spacing piece at the front portion of the tray-like shelf plate 7a, and cool air is provided between the wind guide guide plate 7b and the front end of the shelf plate 7a. A slit-shaped air guide path 7c for passing the air curtain 9 is formed. The product display shelf 7 is installed between a pair of left and right shelf brackets 8, and the shelf bracket 8 has engagement claws 8a formed at the rear end thereof. Via the back of the case body.

  Here, the shelf plate 7a of the commodity display shelf 7 is such that the air guide plate 7b is positioned along the air flow of the cold air curtain 9 shown by the arrow in the figure, which blows out from the cold air outlet 3a to the front opening area of the case body 1. Described in depth dimensions. For the product display shelves 7 arranged in the upper and lower stages, the depth dimension of the shelves arranged on the lower stage side is set to be longer than the depth dimension of the shelves arranged on the upper stage side.

  As a result, the cold air curtain 9 blown obliquely downward from the ceiling portion of the case body 1 through the cold air outlet 3a and the cold air flow 10 blown forward from the back of the interior through the punching hole are the product display shelves 7 at the upper and lower stages. The air is guided along the inner surface of the air guide plate 7b provided at the front of the air guide, and flows down the slit-like air guide path 7c formed behind the air guide plate 7b one after another and is collected in the suction port 3b. The

  Thus, the cold air curtain 9 blown out to the front area of the main body case 1 is maintained in a laminar flow state by the air guide function of the product display shelf 7 to maintain a high cold insulation performance, and the depth dimension of the product display shelf 7 is reduced. It becomes possible to increase the number of items stored by expanding the product display shelf forward of the conventional open showcase (for example, Patent Document 1).

Further, when the product display shelf 7 is moved downward from the attachment position in FIG. 5, the front part of the product display shelf 7 is separated from the airflow of the cold air curtain 9 to the rear, contrary to the above. For this reason, the air guide plate 7b provided in the front part of the merchandise display shelf 7 does not function effectively.

  The present invention has been made in view of the above points, and the object thereof is to solve the above-mentioned problem, and when the mounting height position of the commodity display shelf arranged in the warehouse is moved up and down, this movement is matched. The air guide guide plate 7b provided at the front of the shelf is adjusted and set to an appropriate air guide position with respect to the cold air curtain blown out in the front area of the case body, and the air curtain laminar turbulence and air It is an object of the present invention to provide an open showcase with an improved product display shelf structure that prevents outside air heat from entering the cabinet due to the disturbance of the curtain and leakage of cold air to maintain high cooling performance.

In order to achieve the above object, according to the present invention, product display shelves arranged in the upper and lower stages are arranged in the case body that is open front, and the bottom of the product is placed from the cold air outlet that is arranged on the ceiling of the case body. A cold air circulation open showcase that cools and cools the interior by blowing out a cold air curtain in the front area of the chamber toward the inlet, and the product display shelf is provided with a wind guide plate at the front of the shelf It has a structure in which a slit-shaped air curtain air guide passage is formed inside, and the installation height position in the warehouse is constructed so as to be movable up and down.
The product display shelf is divided into a main body shelf plate and a slide shelf plate that is connected to the front portion of the main body shelf plate so as to be movable in the front-rear direction, and is connected to the front portion of the slide shelf plate. A wind guide plate is provided and an air curtain air guide passage is formed inside the wind guide plate (Claim 1), and the slide shelf plate corresponds to the mounting height of the product display shelf in the cabinet, A cold air curtain that the air curtain air guide passage blows out from the cold air outlet toward the front area of the interior is set to a position that guides the air appropriately.

  As described above, the product display shelf is divided into a main body shelf plate and a slide shelf plate connected to the front portion of the main body shelf plate so as to be movable in the front-rear direction. According to the configuration in which the air guide guide plate is provided and the air curtain air guide passage is formed on the inside, the slide shelf board can be adjusted to the appropriate air curtain according to this movement even when the installation position of the product display shelf is moved up and down. By setting the position according to the wind guide position, laminar flow turbulence occurs due to unnecessary interference with the cold air curtain that blows out from the cold air outlet to the front area of the chamber, and the outside air heat caused by this laminar flow turbulence Intrusion and cold air leakage can be effectively prevented.
