FIG. Figures 3 and 5 are explanatory diagrams of the switch contacts showing the control circuit switching states in the operating states of Figures 2 and 4, respectively, and Figures 6 and 7 are the control circuits when switching the air volume by the motor fan. FIG. 8 is a schematic diagram showing the structure of a conventional open show case. In the figure, 1 is the main body of the refrigerator, 5 is the motor fan, 6 is the air curtain, 7 is the front opening shielding cover (cover body), 8 is the roll mechanism, 10 is the micro switch (shutoff operation detector), and 11 is the lever. , 12 is a spring, 13 is a tap for normal air volume, and 14 is a tap for increased air volume.

Claims

[Scope of Claim for Utility Model Registration] An open-shelf case that forms an air curtain at the front opening of a refrigerator body using a motor fan to keep cool, and includes a front opening shielding cover body that blocks the air curtain from the outside of the refrigerator. An open show case characterized in that the shielding cover body is provided with a shutoff operation detector, and the motor fan is controlled so as to increase the air curtain air volume in conjunction with the operation of the detector.
