Further, the cold air discharge duct 42 is formed with a plurality of cold air outlets 43 at positions corresponding to the lower side of the shelf 33 and the heat insulating partition plate 30 installed in the lower display portion 32.
[0027]
Further, as shown in FIG. 6, communication portions 44 and 45 for communicating the upper display portion 31 and the lower display portion 32 are formed at both side ends of the heat insulating partition plate 30, respectively. 45 are provided with dampers 46 and 47, respectively.
[0028]
Here, the dampers 46 and 47 will be described with reference to FIGS. FIG. 8 is a front view of the damper 46 with the damper 46 opened, and FIG. 9 is a front view of the damper 46 with the damper 46 closed. 8 and 9, reference numeral 48 denotes a partition plate holder for holding the heat insulating partition plate 30 on the side wall of the heat insulating box body 2, and the partition plate holding portion 48 includes the heat insulating partition plate 30, the heat insulating box body 2, and the like. It is assumed that the communication portion 44 or 45 formed between the two is not closed.
[0029]
In addition, dampers 46 or 47 are respectively provided at both end portions of the heat insulating partition plate 30, and the dampers 46 or 47 are configured so as to be rotatable about 90 degrees outward from the vertical direction. It is. Further, a deformable member 49 made of, for example, soft synthetic resin or rubber is provided at the tip of the damper 46 or 47, and the deformable member 49 is tapered toward the tip. When the damper 46 or 47 is rotated outward by approximately 90 degrees toward the outside, the deformable member 49 formed at the tip is brought into close contact with the side wall of the heat insulating box 2 and the deformable member 49 is deformed. Thus, the communication part 44 or 45 is closed. In addition, the dampers 46 and 47 open and close the communication part 44 or 45 by opening and closing the damper 46 or 47, for example, by a damper operation part provided on the outer side wall of the heat insulating box 2.
[0030]
With the above configuration, when the upper display portion 31 and the lower display portion 32 of the second display chamber 11 are similarly used at a low temperature, first, the damper 46 or 47 is brought into a vertical state by the damper operation portion (not shown), The communication parts 44 and 45 are opened. And the upper display part 31 and the lower display part 32 are cooled by operating the control panel which is not shown in figure. Thereby, the cooler installed in the cooling chamber 37 is cooled by operating the separately placed compressor, and the air in the cooling chamber is cooled by the cooler 38. Further, when the blower 39 is operated, the cold air cooled by the cooler 38 is discharged to the cold air discharge duct 42. The cool air discharged to the cool air discharge duct 42 rises in the cool air discharge duct 42, and a part of the cool air is from a shelf 33 installed in the lower display part 32 and a cool air outlet 43 located below the heat insulating partition plate 30. Discharge. The remaining cold air is discharged from the upper end opening of the cold air discharge duct 42, then passes through the communication portion 44 and is discharged into the upper display portion 31.
[0031]
As a result, the cold air discharged from the cold air discharge port 40 can be actively guided to the communication portion 44 by the cold air discharge duct 42 formed extending below the heat insulating partition plate 30. Cold air can be actively discharged into the display unit 31. Therefore, the cool air discharged through the communication part 44 can circulate in the upper display part 31 and cool the inside of the upper display part 31.
[0032]
The cold air circulated in the upper display part 31 flows into the lower display part 32 through the communication part 45. Thereafter, the cold air flowing into the lower display part 32 circulates in the lower display part 32 together with the cold air discharged into the lower display part 32, cools the inside of the lower display part 32, and then cools from the cold air inlet 41. Return to chamber 37. By repeating such a flow of cool air, the inside of the upper display part 31 and the lower display part 32 is cooled to a predetermined temperature.
[0033]
Moreover, when displaying sandwiches, cooked rice, etc. in the upper display part 31 and using beverages etc. in the lower display part 32, the inside of the upper display part 31 is set to a relatively high cooling temperature, It is necessary to make the inside of the lower display part 32 have a relatively low cooling temperature. In such a case, first, the damper 46 or 47 is rotated outward by, for example, 90 degrees by the damper operation section (not shown), and the communication sections 44 and 45 are closed. Then, by operating a control panel (not shown), the upper display unit 31 performs passive cooling, and the lower display unit 32 performs positive cooling.
[0034]
That is, by operating the separately placed compressor, the cooler installed in the cooling chamber 37 is cooled, and the cooler 38 cools the air in the cooling chamber. Further, when the blower 39 is operated, the cold air cooled by the cooler 38 is discharged to the cold air discharge duct 42. The cool air discharged to the cool air discharge duct 42 rises in the cool air discharge duct 42, and a part of the cool air is from a shelf 33 installed in the lower display part 32 and a cool air outlet 43 located below the heat insulating partition plate 30. Discharge. Further, the remaining cold air is discharged from the upper end opening of the cold air discharge duct 42 and is then discharged into the lower display portion 32 because the communication portion 44 is closed.
[0035]
Thereby, the cold air discharged into the lower display part 32 circulates in the lower display part 32, cools the lower display part 32, and then returns to the cooling chamber 37 from the cold air inlet 41. By repeating such a flow of cool air, the inside of the lower display portion 32 is cooled to a predetermined temperature.
[0036]
At this time, since a gap is formed between the glass doors 8 and 9 and the front end of the shelf 33 and the heat insulating partition plate 30, a part of the cool air circulating in the lower display part 32 is The display unit 31 is invaded. Thereby, the upper display part 31 can perform passive cooling, and can form the environment of a comparatively high cooling temperature.
[0037]
With the above configuration, by opening the dampers 46 and 47, the upper display part 31 and the lower display part 32 can form the same temperature environment. Further, by closing the dampers 46 and 47, it becomes possible to suppress the inflow of cool air into the upper display part 31 and to actively cool only the lower display part 32. A cooling environment having a high temperature can be formed, and a cooling environment having a lower temperature than that of the upper display portion can be formed in the lower display portion 32.
[0038]
Therefore, it becomes possible to display sandwiches, cooked rice, etc., which are desirably cooled in a relatively high cooling environment, on the upper display portion 31, and lower beverages, etc., which are desirably cooled in a relatively low cooling environment. It becomes possible to display on the display unit 32. As a result, sandwiches and cooked rice that are desirably cooled in a relatively high cooling environment and beverages that are desirably cooled in a relatively low cooling environment can be simultaneously displayed in one showcase 1. In particular, it is suitable for installation places where the installation area of the showcase is limited.
[0039]
