ある。[Detailed description of the invention] This invention relates to an open showcase that forcibly circulates cold air that has undergone heat exchange with a cooler and closes the opening for taking out products. To reduce the amount of outside air entering from the left and right sides of the opening by blowing out from the rack hole along the side wall of the main body into the refrigerator compartment.

れらのラック孔によって制約され、この結果ラック孔の
前方に収納展示された商品には冷気が当りにくくなり商
品の冷却効果がそれだけ悪くなる。Conventionally, in open showcases, the cold air that has been heat exchanged in the cooler is forced to circulate to close the front opening for taking out products, and the cold air is blown from the back of the refrigerator compartment to the front opening. Since rack holes are formed at the ends to support the display shelves, the blowing surface of the cold air is restricted by these rack holes, and as a result, the cold air hits the products stored and displayed in front of the rack holes. This makes the cooling effect of the product that much worse.
また両側端部のラック孔前方の冷気の流れは、他の部分
からの吹出流の影響により若干負圧気味となり、本体側
壁の内面に沿って前記開口から外気が侵入する不都合を
生じていた。In addition, the flow of cold air in front of the rack holes at both end portions has a slightly negative pressure due to the influence of the blowout from other parts, resulting in the inconvenience that outside air enters from the openings along the inner surface of the side wall of the main body.
本案は以上のような欠点を除去するため、棚を支持する
ラック孔から前方に向けて冷気を吹き出し、この吹出流
によって上記のような外気の侵入を防ぐものである。In order to eliminate the above-mentioned drawbacks, the present invention blows cold air forward from the rack holes that support the shelves, and this blowing flow prevents the outside air from entering as described above.
