構成が示されている。(b) Prior art Japanese Utility Model Publication No. 51-38301 discloses that a large number of discharge holes are provided on the top and back surfaces of the partition inner cylinder, which form a ventilation passage in the gap between the inner cylinder and the inside of the refrigerator, to communicate the ventilation passage with the interior of the refrigerator. Further, a shelf insertion hole is provided in the back side to be long in the horizontal direction, the peripheral edge of the insertion hole is bent inward in an abbreviated shape, and a shelf support is locked in a state where the insertion hole and the shelf correspond to each other. The structure of the shelf is such that the protruding piece provided on the shelf holder engages with the groove provided on the shelf, and when it engages with the groove, it blocks the ventilation path! The configuration of a typical open refrigerated display device is shown.

を奏するとされている。According to this structure, the number of products that require refrigeration is reduced with a simple structure, or products that require refrigeration are displayed on the lower part of the refrigerator, while products that do not like refrigeration are displayed on the upper shelf at the same time. In some cases, by pushing in the shelves and blocking the ventilation path, the area that requires refrigeration is reduced and at the same time the heat infiltration area is reduced, which reduces the required refrigeration capacity and makes the open refrigerated display device economical. It is said to have the effect of making it easier to drive.

する温度が得られない結果となった。However, even if such a configuration reduces the parts that require refrigeration and forms parts that do not like refrigeration, such as heating parts, the forced circulation of cold air that cools the parts that require refrigeration will keep the temperature constant. Warm air from the storage area was sucked in by cold air, causing heat loss in both the refrigerated and heated storage areas, resulting in an unsatisfactory temperature in both areas.

。In the upper part of the heating area, there are a heating device Q5) consisting of an electric heater called a sheathed heater, a heating device 26+ consisting of an infrared lamp that also serves as an illumination lamp, and a reflective member located between these heating devices. A guard and a mesh covering both heating devices and reflective members are installed. Heating device (
25) has a surface temperature of about 600℃,
It radiates infrared rays as shown by the chain line arrow, and the heating device (A) has a surface temperature of approximately 200°C, and radiates infrared rays as shown by the dotted line arrow. The air in the hot storage area (6A) is turned into warm air by convection to heat this hot storage area. In addition, a heating device with a large amount of heat (25
By arranging + behind the heating device (26) with a small amount of heat, the rate at which the radiant heat from the heating device C■ leaks to the outside is reduced. On the other hand, it serves to prevent the radiant heat from the heating device with a large amount of heat (heating device CI! 6) from being directly hit, thereby preventing the nichrome wire of the heating device CI! 6 from reaching abnormal temperatures and impairing its durability. I'm trying to make sure it doesn't get lost.

する。C30) c3+) is a fluorescent light placed on the partition shelf and shelves, C32C (311″11.) is a guard placed on the partition shelf and the tip of the rod to prevent products from falling. (E)) is a fluorescent light ( A suction prevention plate made of resin that also doubles as a shade plate is installed at the tip of the partition shelf U so as to cover the air outlet 03).
The hot air in the heating area (6A) is prevented from being sucked in by the cold air by the entrainment action of the cold air blown out from the storage area and directed toward the suction port (7).

) and a partition shelf that insulates the mutual heat conduction 0';! This can be prevented by the insulation effect of J, and the upper part of the storage space (6) is made into a heating area (6A), and the lower part is made into a refrigeration area (6B), and the warm air from both heating devices (c) (support)) is used to prevent heating. In order to heat the storage area (6A) and cool the refrigeration area (6B) with forced circulation cold air by the cooler θO) and the blower 01), the storage space (6) is heated.
Even if the front is open, warm air with low specific gravity will rise,
The cold air with a large specific gravity will fall, preventing mutual contact between the two, and the suction prevention plate installed at the tip of the partition shelf (12) will separate the heating area (6A) and the refrigerating area (6B). By increasing the distance between the warm air and the cold air, the entrainment effect of the cold air can be prevented from reaching the warm air.
