Description

  The present invention relates to an open showcase that displays products while cooling products in a display room having at least one surface opened in a heat insulating wall.

  Conventionally, an open showcase that is formed by cooling the display room that opens to the front has a main body constituted by a heat insulating wall having a substantially U-shaped cross section and side plates attached to both sides of the heat insulating wall. Cool air is discharged from the cold air discharge port formed at the upper edge of the opening, and the cold air is sucked in from the cold air intake port formed at the lower edge of the opening, thereby forming a cold air curtain at the front opening and a predetermined temperature inside the display room. It has cooled down.

  However, the cold air curtain of such an open showcase having an open front is often disturbed by the traffic of people and the influence of wind from air conditioners in the store. Due to the occurrence of this disturbance, the cool air in the display room is likely to leak to the outside, the cooling efficiency is lowered, the product cannot be cooled to a predetermined temperature, or the energy consumption is increased, contributing to energy saving. There is a problem that can not be done.

  Therefore, conventionally, in order to protect the disturbance of the cold air curtain and suppress the cold air leakage, it is conventionally attached to the front opening of the display room so that it can be drawn out from the transparent opening made of soft synthetic resin or from the upper edge of the opening. A roll curtain night cover is attached. This prevents the inflow of outside air into the display room and suppresses inconvenience that the temperature in the display room rises (see, for example, Patent Document 1 and Patent Document 2).
