냉동 쇼 케이스용 유리문의 결로 방지장치{DEW PREVENTING DEVICE FOR GLASS DOOR OF FREEZING SHOWCASE} Condensation prevention device of glass door for freezing show case {DEW PREVENTING DEVICE FOR GLASS DOOR OF FREEZING SHOWCASE}

본 고안은 주로 백화점 또는 슈퍼마켓 등에 설치되어서 냉동 상품을 보관 및 전시하도록 된 냉동 쇼 케이스에 있어, 유리문의 결로 방지 장치에 관한 것이다. 더욱 상세하게는 케이스 본체의 내측 상부에 설치된 냉각공기 토출구와 유리문 사이의 내측부에 전열선이 설치되고, 이 전열선에서 발생되는 열이 유리문의 내면을 가열하여서 표면에 발생되는 결로를 방지하도록 된 것이다. 따라서 쇼 케이스의 내부에 보관된 상품을 냉동 상태로 안전하게 보관하고, 또한 유리문을 통해 내부의 상품이 선명하게 전시될 수 있게 한 것이다.The present invention mainly relates to a condensation preventing device of a glass door in a refrigeration show case which is installed in a department store or a supermarket to store and display a frozen product. More specifically, a heating wire is installed on the inner side between the cooling air discharge port and the glass door installed in the upper part of the case body, and heat generated from the heating wire heats the inner surface of the glass door to prevent condensation generated on the surface. Therefore, the product stored inside the showcase is safely stored in a frozen state, and also through the glass door to be able to display the goods inside clearly.

통상 냉동 쇼 케이스는 유리문을 통해 내부의 상품을 볼 수 있게 되었다. 그러나 냉동 쇼 케이스의 내부와 유리문 외부의 온도 차이로 인해 외부 공기의 상대습도가 올라가고, 이것이 이슬점에 이르면 공기 중의 수증기는 물방울이 되어 유리문의 표면에 맺히게 된다. 따라서 쇼 케이스의 내부에 저장된 상품이 유리문에 맺힌 이슬 때문에 외부로 선명하게 표출되지 못하는 결점이 있었다. 종래에도 이와 같은 문제점을 해결하기 위하여 냉각기에서 발생되는 열을 유리문의 내면에 송풍시 켜서 유리문을 가열하는 방법이 제안된바 있었다. 그러나 이 경우 구성이 매우 복잡하고, 또한 냉동 쇼 케이스의 냉동 효율을 떨어뜨려서 상품을 안전하게 보관하지 못하는 등의 폐단이 있었다. 따라서 냉동 쇼 케이스의 유리문에 발생되는 결로를 효과적으로 방지할 수 있는 고안이 요구되고 있다. Typically, frozen showcases are able to see inside goods through glass doors. However, due to the difference in temperature between the inside of the freezing show case and the outside of the glass door, the relative humidity of the outside air increases, and when it reaches the dew point, water vapor in the air becomes water droplets and forms on the surface of the glass door. Therefore, there was a drawback that the goods stored inside the showcase could not be clearly displayed to the outside due to dew on glass doors. Conventionally, in order to solve such a problem, a method of heating the glass door by blowing heat generated from the cooler to the inner surface of the glass door has been proposed. In this case, however, the configuration was very complicated, and the refrigeration efficiency of the refrigeration show case was reduced, resulting in the inability to safely store the goods. Therefore, it is required to devise a way to effectively prevent condensation generated in the glass door of the freezing show case.

본 고안은 상기한 종래의 문제점을 감안하여서 고안된 것으로, 유리문의 하부 내측부에 설치된 전열선의 열이 냉각공기 토출구에서 전방으로 송풍되는 냉각공기의 진행 방향으로 편승하여 유리문의 내면을 골고루 가열함으로서 표면에 발생되는 결로를 방지할 수가 있게 되었다. 따라서 쇼 케이스 내의 상품을 유리문을 통해 외부로 선명하게 표출할 수 있고, 또한 쇼 케이스 내부의 온도를 균일하게 유지시켜서 보관된 상품을 냉동 상태로 안전하게 보관하게 된 냉동 쇼 케이스를 제공하는데 그 목적이 있다. The present invention has been devised in view of the above-described conventional problems, and the heat of the heating wire installed in the lower inner portion of the glass door is generated on the surface by heating the inner surface of the glass door evenly by piggybacking in the traveling direction of cooling air blown forward from the cooling air discharge port. Condensation can be prevented. Therefore, the purpose of the present invention is to provide a frozen showcase that can clearly display the goods in the showcase to the outside through the glass door, and keep the stored goods safely in the frozen state by keeping the temperature inside the showcase uniform. .

본 고안에서는 상기한 문제점을 해결하기 위하여, 쇼 케이스 본체의 내면 상부에 설치된 냉각공기 토출구와 유리문 사이의 내측부에 전열선이 설치되게 한 구성인바, 냉각공기 토출구에서 전방으로 분출되는 냉각공기의 진행 방향에 편승하여 상승되면서 전열선의 열이 유리문의 내면에 골고루 전달되어서 균일하게 가열되게 함으로서 유리문의 표면에 발생되는 결로를 방지할 수 있게 된 것이다. In the present invention, in order to solve the above problems, the heating wire is installed on the inner side between the cooling air discharge port and the glass door installed on the upper inner surface of the show case body, the cooling air discharge port in the forward direction of the cooling air discharged forward As it rises by piggybacking, the heat of the heating wire is evenly transmitted to the inner surface of the glass door so as to be uniformly heated to prevent condensation occurring on the surface of the glass door.

본 고안은 전열선의 열이 냉각공기 토출구에서 전방으로 분출되는 냉각공기의 진행 방향에 편승하여 상승되면서 유리문의 내면에 골고루 전달되어서 가열함으로서 표면에 발생되는 결로를 방지할 수가 있다. 따라서 쇼 케이스 내의 상품이 유리문을 통해 외부로 선명하게 표출될 수 있어서 소비자가 쇼 케이스 내의 상품을 정확히 선별할 수 있도록 도와주고, 또한 내부의 온도를 균일하게 유지시켜서 쇼 케이스 내부에 보관된 상품을 냉동 상태로 안전하게 보관하게 된 유용한 고안이다. The present invention can be prevented from condensation generated on the surface of the heating wire is heated evenly transferred to the inner surface of the glass door while the heat of the heating wire is piggybacked in the traveling direction of the cooling air ejected forward from the cooling air discharge port. Therefore, the goods in the showcase can be clearly displayed to the outside through the glass door, so that the consumer can sort out the goods in the showcase accurately, and keep the temperature inside uniformly to freeze the goods stored inside the showcase. It is a useful design that has been stored safely in a state.
