Description

  The present invention relates to a condensed water guide plate and a storage.

  A constant temperature and high humidity store is known as a storehouse which can preserve perishable foods for a long time without drying (for example, patent documents 1 and 2). This type of constant-temperature high-humidity store supplies a cold body with a main body made of a heat-insulating box opened to the front side, a storage room made of a heat-conducting box opened to the front side and disposed inside the main body. A cold air supply device is provided.

  A space surrounding the storage chamber is provided between the main body and the storage chamber, and the space is used as a cool air passage for circulating the cool air supplied from the cool air supply device. A so-called indirect cooling system is employed in the constant temperature and high humidity storage, and the storage chamber is indirectly cooled by cooling the wall surface of the storage chamber by the cool air flowing through the cool air passage.

  In this type of constant-temperature high-humidity store, if the temperature difference between the wall of the storage room and the air in the storage room is large, the air in the storage room is cooled below the dew point temperature, and moisture in the air is transferred to the wall of the storage room. May cause condensation. For example, water droplets adhering to the ceiling surface in the storage chamber may fall and hit the storage items in the storage chamber, thereby contaminating the storage items. Therefore, as shown in Patent Documents 1 and 2, a dew condensation water guide plate is attached in the storage chamber so as to cover the ceiling surface while keeping a distance from the ceiling surface.

  Since the condensed water guide plate is installed in the storage room in an inclined state so as to descend from the front side toward the rear side, when a water drop falling from the ceiling surface is received on the upper surface of the condensed water guide plate, It moves to flow to the rear side of the storage room under its own weight.

  By the way, the moisture in the storage chamber also condenses on the lower surface of the condensed water guide plate. Therefore, the condensed water adhering to the lower surface moves to the rear side of the storage chamber along the lower surface while following the inclination of the condensed water guide plate.
