PROBLEM TO BE SOLVED: To provide a two-temperature type show case that can prevent an article from changing in food texture and taste badly by solving the problem that the temperature of a bottom part of a high-temperature area becomes lower than the temperature of other regions, and also can prevent warmed air in the high-temperature area from being dissipated to outside the show case.SOLUTION: Cold air is supplied to a low-temperature area A1 of a two-temperature type show case through a first flow passage 4 and a first outlet 11 of an intermediate duct 9. Normal-temperature air is circulated through a second flow passage 5 and a second outlet 12 and an air curtain is formed before both areas A1, A2. A third flow passage 6 branching off from the second flow passage 5 is connected to an upper side of the first flow passage 4, and those flow passages 4, 6 are sectioned vertically with a damper part 41 of the intermediate duct 9. A heater 23 is arranged in the third flow passage 6 and warmed air is blown out from the third outlet 13 to a high-temperature area A2 to prevent a bottom part of the area from being at low temperature. |
