As a result, when the decorative frame 62 is inserted, the upper engaging portion 83 and the lower engaging portion 84 can bend up and down, reducing the frictional resistance and causing the claws to catch on the way. There is no.
[0036]
Next, the operation of the frozen showcase configured as described above will be described. The refrigerant is adiabatically compressed by the compressor 6 to become a high-temperature gas, and is sent to the frame heater 10. As a result, the frame 4 is heated to prevent water droplets attached due to dew condensation or the like from freezing, and the sliding surfaces 68 and 69 are prevented from freezing and the lid 5 does not move.
[0037]
Thereafter, the refrigerant is sent to the condenser 7 and liquefied by releasing heat to the outside air via the outer case 1. The liquefied refrigerant, from which moisture is removed by the dryer 11, is decompressed by the decompression device 12 and sent to the evaporator 13, evaporates and vaporizes in the evaporator 13 to cool the inner case 2. Thereby, the inner case 2 functions as a freezing room.
