Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The main body of the showcase 1 is composed of a U-shaped heat insulating material 2 and a partition plate 3 that open to the front, and a cold air circulation duct 4 is formed between the partition plate 3 and the heat insulating material 2 from the back to the top. Has been. Further, a deck van 5 extending forward is provided at the lower end of the cold air circulation duct, and the interior 6 is configured inside these heat insulating material, partition plate and deck van. A lower duct 7 communicating with the cold air circulation duct and constituting a part thereof is formed below the deck van.
The upper end of the cold air circulation duct communicates with the upper cold air discharge port 9 located at the upper edge of the front opening in the cabinet, and a fluorescent lamp support member 10 for illuminating the product is installed in the front part. The front end of the lower duct is located at the lower edge of the front opening in the cabinet, and communicates with the cold air inlet 11 composed of a plurality of slits. A blower 8 for supplying cold air is disposed in a lower duct below the deck pan 5, and a cooler 12 constituting a refrigeration cycle of a cooling device is provided vertically in a cold air circulation duct at the rear of the inside of the cabinet.
In the warehouse, an intermediate duct 14 and a plurality of product display shelves 13 are erected up and down in seven steps in this embodiment. Each merchandise display shelf has a pair of left and right brackets 15 having hook-like claws protruding rearward at the rear end, a shelf plate 16 that is detachably attached across the brackets, and a lower surface of the shelf plate. It comprises an attached electric heater (not shown) for heating.
Each product display shelf 13 is stored in the cabinet by removably engaging the claw of the bracket with a plurality of holes 18 formed in the vertical direction on a shelf column 17 attached to a partition plate in the showcase. It is installed so that the vertical position (height) can be changed. In this case, the numbers and colors corresponding to the products are assigned to the shelf columns 17 (the predetermined heights of the shelf columns) so that the shelves can be efficiently arranged according to the height dimensions of the products to be displayed (cans, plastic bottles, etc.). It is good to add it to the position.
In each figure, 14 is an intermediate duct of the present invention. A product display shelf 13 is formed on the intermediate duct 14, and communicates with a shelf lower cool air discharge port 18 that opens obliquely forward and downward at the front end of the intermediate duct 14, and the rear end opens with a hole. . Further, the shelf duct member is provided with a flapper operation section 20 that is attached to be movable in the front-rear direction.
The wrapper operation unit 20 has a structure in which a protrusion protrudes when the operation unit is operated. Further, a plurality of flapper stoppers 21 are provided in the cold air circulation duct 4 and a plurality of movable flappers 22 are provided in the cold air circulation duct 4 so as to close the holes.
When the flapper operation unit 20 installed in the intermediate duct 14 is operated, the flapper operation unit 20 passes through the hole, and the flapper 22 adjacent to the hole rotates. The rotated flapper 22 contacts the flapper stopper 21 and does not rotate any further. Thereby, the wall which changes the flow of cold air in the cold air circulation duct 4 is made.
Therefore, the cold air flowing in the cold air circulation duct 4 does not flow further upward due to the flapper 22 and the flapper operation unit 20. The cold air flows from the hole opened by the flapper 22 to the intermediate duct 20. The cool air flowing in the intermediate duct 20 passes through the under shelf cool air discharge port 18 that opens obliquely forward and downward at the front end, and is blown downward to form an air curtain.
The cool air blown from the cool air discharge port 18 below the shelf flows toward the cool air suction port 11, so that the products displayed below the intermediate duct 14 can be sold as refrigerated products.
Since the product display shelf 13 above the intermediate duct 14 is heated by operating a heater (not shown) built in the product display shelf, it is possible to sell warm products.
Thus, the display ratio of the refrigerated product and the warmed product can be easily changed simply by changing the insertion position of the intermediate duct 14.
By forming the support shaft of the flapper 22 above the hole 19 through which the flapper operation section 20 of the partition plate 3 enters, the cool air in the cool air circulation duct 4 can be guided into the intermediate duct 14.
By having the flapper stopper 21 on the heat insulating material 2 side of the cold air circulation duct 4, the flapper 22 is reliably stopped at the flapper stopper 21 so that the cold air does not flow above the flapper operation unit 20. it can.
By forming a plurality of cold air introduction holes that guide the cold air to the intermediate duct 14 at approximately the same height as the holes 19 through which the flapper operation unit 20 connected to the intermediate duct 14 has passed, a uniform air curtain in the left-right direction in the cabinet Can be formed.
The partition plate 3 will be described. The size of the plurality of holes 23 provided in the partition plate 3 is arbitrary. The size and number of the holes 23 are determined by the position of the partition plate 3 in which the holes 23 are provided. This is because the wind force of the cold air flowing in the cold air circulation duct 4 is different, so that it is adjusted, and the strength of the partition plate 3 is also maintained.
In addition, although the said Example demonstrated the case where a merchandise display shelf was seven steps, it is not restricted to this number of steps.
