Claims

[Scope of Claim for Utility Model Registration] (1) Inside the case body, which consists of an insulating wall with an opening for taking out products on the front, there is a refrigerator compartment connected to the opening by a partition plate, and a cold air passageway in which a cooler is installed. and a protective air flow passage, and the ends of the cold air passage and the protective air flow passage are made to face above and below the opening as an air outlet and a suction opening, and an air curtain of cold air flow and protective air flow is formed in the opening. In the refrigeration/refrigeration open-show case, a heat exchanger connected to the compressor discharge pipe of the refrigeration system and a blower are installed in the lower space of the case body, and the blower is ON/OFF controlled on the leeward side of the heat exchanger. A refrigerated open storage case characterized by being equipped with a temperature sensor. (2) The inside of the case body, which consists of an insulating wall with an opening for taking out products on the front, is divided by a partition plate into a refrigerator compartment connected to the opening, and a cold air passageway in which a cooler is installed. In the refrigeration/refrigeration open case, which faces above and below the opening as a blowout port and a suction port to form an air curtain of cold air flow at the opening, a compressor discharge pipe of the refrigeration system is installed in the lower space of the case body. A refrigerated/refrigerated open case, characterized in that a heat exchanger and an air blower connected to the heat exchanger are installed, and a temperature sensor for controlling ON/OFF of the air blower is provided on the lee side of the heat exchanger.
