Description

SHOWCASE HAVING DEW CONDENSATION REMOVAL}

The present invention relates to a showcase for refrigerating a product using a refrigeration cycle.

Generally, a showcase is a product that displays fresh foods such as meat, vegetables and beverages while maintaining freshness, and generates cold air by using a refrigeration cycle and keeps the freshness by refrigerating the product with this cold air.

The showcase is able to see the inside of the product through the glass door. The relative humidity of the outside air rises due to the temperature difference between the inside of the showcase and the outside of the glass door. When this reaches the dew point, water vapor in the air becomes waterdrop, .

Therefore, there is a drawback that the merchandise stored inside the show case can not be clearly displayed to the outside because of the dew formed in the glass door. In order to solve such a problem, a method has been proposed in which a hot wire is installed on a glass door to prevent dew formation.

However, since the glass door preventing the dew formation is required to use a double-layered glass having a built-in heat ray, the cost of the product is increased and the display effect of the product displayed by the heat ray installed on the glass door is deteriorated.
