Description

  The present invention relates to a showcase capable of making a temperature environment in a lower region different from a temperature environment in an upper region with a partition plate attached to a product display room as a boundary.

  There is a demand for a showcase that can display products efficiently in a store with limited space such as a convenience store. As a response to such a demand, a showcase capable of simultaneously displaying a cooled product (refrigerated product) and a warmed product (warmed product) is known. A merchandise display room having an open front is defined inside the showcase, and a rear duct is defined on the back of the merchandise display room. A heat exchanger (evaporator) is disposed inside the back duct, and heat is absorbed from the air passing through the back duct, and the air passing through the back duct is cooled. And the air cooled by the back surface duct is discharged from the front upper edge part of a goods display room, and produces | generates an air curtain in the front of a goods display room. In addition, a plurality of shelf boards can be attached in the vertical direction of the product display room. A heater is wired on each shelf board, and the product displayed on the shelf board is heated when electricity is passed through the heater. In addition, a partition plate can be attached to each shelf plate. By attaching the partition plate to a shelf plate attached at an arbitrary position, the lower region and the upper side are separated from the partition plate attached to the shelf plate. It is divided into areas. The partition plate has a damper that can protrude into the rear duct.When the damper protrudes into the rear duct, the rear duct is partitioned, and the cooled air passes from the rear duct to the inside of the partition plate via the damper. It comes to flow. And the air (cooled air) which flowed into the inside of a partition plate is discharged from a front edge.

  According to this showcase, by attaching a partition plate to a shelf plate attached at an arbitrary position, the partition is divided into a lower region and an upper region with the partition plate as a boundary. And if a damper is made to project in a back duct, a back duct will be partitioned off. And the air cooled by the heat exchanger (evaporator) is discharged from the front edge opening of a partition plate via a damper from a back surface duct, and an air curtain is produced | generated in the front surface of a lower area | region. For this reason, the commodity displayed on the shelf board attached to the lower region is cooled. On the other hand, since the rear duct is partitioned, the cooled air does not flow into the upper region. For this reason, the goods displayed on the shelf board attached to the upper area are not cooled (room temperature). Here, when electricity is supplied to the heater wired on the shelf attached to the upper region, the product displayed on the shelf is warmed (see, for example, Patent Document 1). Further, if the amount of air flowing through the rear duct (the flow rate of the air curtain) is adjusted, it is possible to make it cool.

The air is taken in and discharged from the front edge of the partition plate 5. Then, an air curtain is generated in front of the lower region of the partition plate 5 and cooled. On the other hand, since the outer duct 26b is not shielded, air is discharged from the air outlet 22C1, and an air curtain is also generated on the front surface of the commodity display chamber 3. As a result, the upper region of the partition plate 5 is slightly cooled. Therefore, when the cooled product is displayed in the lower region of the partition plate 5 and the weakly cooled product is displayed in the upper region of the partition plate 5, the damper 6 is projected from the partition plate 5 to the inner duct 25b.

  In the showcase shown in FIG. 7, when the damper 6 protrudes from the partition plate 5 mounted on an arbitrary shelf plate 4 to the outer duct 26b, the damper 6 shields the inner duct 25b and the outer duct 26b, and at the same time, the inner duct 25b and the outer duct 26b. Air is taken into the inside of the partition plate 5 from the duct 26 b, and air is discharged from the front edge of the partition plate 5. Then, an air curtain is generated in front of the lower region of the partition plate 5 and cooled. On the other hand, since the inner duct 25b and the outer duct 26b are shielded, air is not discharged from the outlets 24c1 and 22c1, and the upper region of the partition plate 5 is not cooled. Therefore, when the cooled product is displayed in the lower region of the partition plate 5 and the room temperature product or the warmed product is displayed in the upper region of the partition plate, the damper 6 protrudes from the partition plate 5 to the outer duct 26b. .
