載のシヨーケース。[Scope of Claim for Utility Model Registration] (1) In a show case that cools the inside of a refrigerator with cold air heat-exchanged by an evaporator and illuminates the inside of the refrigerator with a lighting lamp, the lighting lamp can be turned ON/OFF.
The defrosting device is brought into operation in conjunction with the OFF operation of the F-controlled lighting switch, and the defrosting operation by the defrosting device is stopped in response to a detection signal of a predetermined temperature from a cooling fin temperature sensor provided on the cooling fin of the evaporator. A show case characterized by its composition. (2) The defrost timer is activated by turning off the lighting switch, the defrost timer is reset in response to a detection signal of a predetermined temperature from the cooling fin temperature sensor, and the compressor is activated in accordance with the timing operation completion signal of the defrost timer. 2. The show case according to claim 1, wherein the evaporator is defrosted by turning off the evaporator. (3) The show case according to claim 2, wherein when the cooling fin temperature sensor detects a temperature higher than 0° C., the defrost timer is reset.
