  • a refrigerated showcase in which an air curtain is formed at a portion opened to the front side of a display chamber, as disclosed in a patent document 2 below, is also well known.
  • the refrigerated showcase as disclosed in the patent document 2 is of a structure which makes it possible to form the air curtain in such a way that a ceiling part covering the upper side of the display chamber is extended ahead of the front end of a mounting lateral surface which constitutes a surface on the side where the foodstuffs in the display chamber are placed, thereby forming, in the ceiling part, a flow passage which permits refrigerated air to flow forward, and forming, at the front end side of the ceiling part, an air vent for the air flowing through the flow passage, wherein the direction in which the air is vented from the vent is oriented directly downward.
  • This structure for forming the air curtain is complicated as described the above. Besides, refrigerated air is easily discharged from the front side of the display chamber to the outside, thereby resulting in causing the problem that energy efficiency is degraded.
  • An object of the present invention is to provide a refrigerated showcase comprising a display chamber in which foodstuffs are displayed, a mounting lateral surface which is formed in the display chamber and constitutes a surface on the side where the foodstuffs are placed, and a vent which is positioned directly above the mounting lateral surface and from which refrigerated air is vented, whereby the refrigerated showcase makes it possible to keep the quality of the foodstuffs satisfactory and to achieve satisfactory energy efficiency, without the need for any complicated structure.
  • the present invention provides a refrigerated showcase with which foodstuffs are displayed, the refrigerated showcase comprising a display chamber in which the foodstuffs are displayed, a cover which covers at least the front side of the display chamber, a mounting lateral surface which is formed in the display chamber and constitutes a surface on the side where the foodstuffs are placed, and a vent which is positioned directly above the mounting lateral surface and from which refrigerated air is vented, wherein the cover is configured such that the foodstuffs displayed in the display chamber can be viewed from the outside, wherein the vent is positioned behind the front end of the mounting lateral surface in plan view, and wherein the direction in which the air is vented from the vent is oriented forward in plan view.
  • the vent may also be configured such that the air is vented slantly downward to the front toward the front end of the mounting lateral surface.
  • a space positioned on the front side of the mounting lateral surface in regards to the display chamber may also be formed with a suction port through which the air is sucked.
  • the cover may also be formed ranging from the front end side of a ceiling part covering at least a part of the upper side of the display chamber to the front surface side of the suction port, wherein the ceiling part is formed with a ceiling-side flow passage which constitutes a flow passage of refrigerated air and communicates with the vent.
  • the vent may also be of a laterally long shape.
  • the refrigerated showcase has an inside openable/closable opening constituting an openable/closable opening to open and close the back surface side of the display chamber, and an outside openable/closable opening constituting an openable/closable opening to open and close a back surface-side portion of an outer wall of the refrigerated showcase, wherein the inside (front-side) openable/closable opening and the outside (rear-side) openable/closable opening are respectively positioned such as to be at least partly overlapped together in back view, and wherein a back surface-side flow passage constituting a flow passage which permits the refrigerated air to flow therethough is formed between the inside (front-side) openable/closable opening and the outside (rear-side) openable/closable opening.
  • the openable/closable opening may also be an opening constituted of a plate-shaped sliding door which is capable of laterally sliding for opening and closing.
  • An inside sliding door serving as the sliding door constituting the inside openable/closable opening may also be formed with an air introducing part through which the air flowing through the back surface-side flow passage is introduced into the display chamber.
  • This refrigerated showcase may also be provided with another display chamber or a stock chamber which is formed, as a separate space, directly below the display chamber and in which the foodstuffs are displayed or stocked.
  • This refrigerated showcase may also be equipped with a voltage generator in which one output terminal thereof is connected to an electrode disposed in the display chamber.
  • the cover is provided to cover at least the front side of the display chamber, and the position and direction in which the air is vented are appropriately oriented such that the direct contact of the refrigerated air with the foodstuffs displayed in the display chamber hardly occurs. For that reason, it can be appreciated that the quality of the foodstuffs can be kept satisfactory, while satisfactory energy efficiency can be achieved, without the need for any complicated structure.
