And a damper for adjusting the amount of air blown out from the first vent and the third vent, and a heating means for warming an upper portion of the reservoir. Installation, and propose an open showcase disposed in the air passage between the cooling means and of the ventilation holes with the damper of the second to the blowing fan.

According to the present invention, when used as a refrigerated, heated open showcase, the upper part is heated by the heating means than the partition plate in the storage. In addition, the air in the air passage is cooled by the cooling means, and again, the ejection of the cold wind from the first vent is stopped by the damper, and the air flowing into the air passage from the second vent is ejected from the third vent through the duct. do. The inside of the reservoir lower than the partition plate is cooled by the cold air emitted from the third vent.

In addition, the cold air ejected from the third vent is introduced into the air passage through the second vent, and an air curtain is formed in the opening lower than the partition plate.

As a result, the upper portion is the warm portion and the lower portion is the refrigeration portion than the partition plate in the reservoir.

In addition, when used as a refrigerated open showcase, the heating by the heating means is stopped. Moreover, the blower blows off the cold wind from a 1st ventilation opening. The cold air blown out of the first air vent cools the entire inside of the reservoir, and then flows into the air passage at the second air vent. As a result, an air curtain is formed on the entire surface of the opening, and all of the refrigerators become refrigerated portions.
