  Here, when such a face-to-face showcase is an open showcase that also opens at the front, the top wall of the heat insulating wall that becomes the top surface of the display room is more than the bottom wall in consideration of the ease of taking out products by the customer. It will be greatly retracted, and the front will be opened obliquely upward and forward. With such a structure, it becomes impossible to install a cooler at the top of the display room as in the above publication, and it will be installed below the display room. Thus, there is a problem whether it is discharged into the display chamber and circulated.

  The present invention has been made to solve the conventional technical problems, and in an open showcase in which the front and rear surfaces of the display chamber are open and the rear surface is closed with a door, the cooler is placed below the display chamber. The purpose is to circulate cool air smoothly even when installed.

The open showcase of the present invention constitutes a display chamber having a front surface and a rear surface opened in a heat insulating wall, and the opening on the rear surface is closed by a door so as to be freely opened and closed, and constitutes the bottom surface of the display chamber. A deck pan, a cooling chamber formed between the deck pan and the bottom wall of the heat insulating wall, a cooler and a lower blower installed in the cooling chamber, a front lower portion of the door, and communicated with the rear end of the cooling chamber The lower cool air discharge port is configured at the upper part of the display room, and is connected to the upper fan chamber containing the upper fan and the upper fan chamber, and is configured at the upper front side of the door corresponding to the upper portion of the lower cool air discharge port. The upper cold air inlet and the upper fan chamber communicate with the upper cold air outlet opening at the upper front opening of the display room and the front end of the cooling chamber and open at the lower front opening of the display room. a lower cold air suction port which covers the lower discharge ports And a first blow-out portion that blows out cool air upward toward the front side of the door and a front side of the first blow-out portion, and this cover blows out cool air obliquely upward and upward. It is characterized in that two blowout portions are formed .

An open showcase according to a second aspect of the present invention is characterized in that the deck pan includes a vertical wall rising from the rear edge, and the vertical wall protrudes slightly above the front end of the cover.

  In the present invention, in an open showcase in which a front chamber and a rear surface are opened in a heat insulating wall and the rear surface opening is closed by a door, the deck pan constituting the bottom surface of the display chamber, A cooling chamber configured between the deck pan and the bottom wall of the heat insulating wall, a cooler and a lower blower installed in the cooling chamber, and a lower cool air discharge port configured at the lower front side of the door and communicating with the rear end of the cooling chamber And an upper fan chamber configured in the upper part of the display chamber and containing the upper fan, and communicated with the upper fan chamber, and configured as an upper part of the front side of the door corresponding to the upper part of the lower cold air discharge port. The upper cool air discharge port that is configured to communicate with the opening and the upper fan chamber and opens at the upper front opening of the display chamber, and the lower cool air suction that communicates with the front end of the cooling chamber and opens at the lower front opening of the display chamber So that the deck Cooled air exchanged with the cooler installed in the cooling chamber between the bottom wall and the heat insulating wall is discharged from the lower cold air discharge port by the lower blower, and this discharged cold air is closed from the upper cold air suction port by the upper blower It is possible to form a cold air circulation that is sucked along the front surface of the door in the state, discharged from the upper opening of the front of the display chamber through the upper cold air outlet, and sucked from the lower cold air inlet.

  As a result, even in the case of an open showcase where the front and rear surfaces are open and the rear surface is closed with a door, the cooler can be circulated smoothly in the display chamber even when the cooler is installed below the display chamber. Can be cooled.

In particular, the cover further includes a cover for covering the lower cold air discharge port, and the cover is configured on the front side of the first blow-out portion and the first blow-out portion for blowing the cold air upward toward the front side of the door, and obliquely front upper Since the 2nd blowing part which blows off cool air toward is formed , it becomes possible to discharge a part of cool air from the back lower part into the display room, and the cooling effect in the display room is improved.

Furthermore, if a vertical wall is formed upright from the rear edge of the deck pan as in the second aspect of the invention, and the vertical wall protrudes slightly above the front end of the cover, the product displayed on the deck pan is placed in front of the cover. Even when riding on the part, since the gap is formed between the second blowing part and the product by the vertical wall, it is possible to prevent the disadvantage that the discharge of the cold air from the second blowing part is completely blocked. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a vertical side view of an open showcase 1 according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a circle A portion of FIG.

  The open showcase 1 according to the embodiment is an open type so-called face-to-face showcase that displays and sells products G such as side dishes at a store such as a supermarket. The open showcase 1 constitutes a display chamber 6 whose front and rear surfaces are open in a heat insulating wall 4 comprising a bottom wall 2 and a top wall 3 mounted on the bottom wall 2 via left and right angles 5. The rear opening is closed by a sliding door 7 so as to be opened and closed. Side plates (not shown) are attached to the left and right sides of the heat insulating wall 4.

  The top wall 3 retreats relatively larger than the bottom wall 2, whereby the opening on the front surface of the display chamber 6 opens obliquely forward and upward, improving the ease of taking out the product G by the customer. A deck pan 8 serving as a bottom surface of the display chamber 6 is attached to the upper side of the bottom wall 2, and a cooling chamber 9 is formed between the deck pan 8 and the bottom wall 2. In the cooling chamber 9, a cooler 11 and a lower blower 12 which are located below the display chamber 6 and constitute a refrigerant circuit of the cooling device are installed.

  On the rear side of the deck pan 8, a lower cool air discharge port 13 is formed at the lower portion immediately before the door 7, and communicates with the rear end portion in the cooling chamber 9. The lower cold air discharge port 13 is covered with a cover 14 as shown in FIG. The cover 14 is formed with a slit (first blowing portion) 16A opening upward in the rear horizontal plane 14A, and on an inclined surface 14B formed obliquely so as to be lowered forward on the front side of the horizontal plane 14A. A slit 16B that opens obliquely forward is formed. A vertical wall 8A is formed on the rear edge of the deck pan 8 so as to rise substantially perpendicularly upward. The vertical wall 8A is in contact with the front end of the cover 14 and protrudes slightly above the front lower end of the inclined surface 14B (see FIG. 2).

  A lower cold air inlet 18 is formed at the lower edge of the front opening of the display chamber 6, and the lower cold air inlet 18 communicates with the front end of the cooling chamber 9. A transparent glass guard 19 is erected on the front side of the lower cold air inlet 18.

  On the other hand, an upper fan chamber 21 is configured in the top wall 3, and an upper fan 22 is installed in the upper fan chamber 21. Further, an upper cold air inlet 23 is formed at a position corresponding to the upper portion of the lower cold air outlet 13 immediately above the door 7, and communicates with the rear end of the upper blower chamber 21. Further, an upper cold air discharge port 24 is formed at the upper front opening of the display chamber 6, and the upper cold air discharge port 24 communicates with the front end of the upper blower chamber 21.

  Reference numeral 26 denotes a transparent glass ridge that protrudes forward from the top wall 3 and is bent obliquely downward, and 27 is a shelf that is erected on an angle 5 column. Both the collar 26 and the shelf 27 protrude to a substantially middle part in the front-rear direction of the display chamber 6.

  The operation will be described with the above configuration. Now, it is assumed that the door 7 is closed. Further, the product G is displayed on the deck pan 8 and the shelf 27. In this state, when the compressor (not shown) of the cooling device installed in the machine room 31 configured below the bottom wall 2 and the blowers 12 and 22 are operated, the cooler 11 exhibits a cooling action. The cool air exchanged with the cooler 11 is accelerated by the lower blower 12 and discharged upward from the lower cool air discharge port 13. In this case, the cold air discharged from the lower cold air discharge port 13 is blown out by the slits 16 </ b> A and 16 </ b> B of the cover 14. That is, cold air is blown upward from the slit 16 </ b> A toward the front side of the door 7. On the other hand, cold air is blown out into the display chamber 6 below the shelf 27 from the slit 16B obliquely forward and upward (indicated by an arrow in FIG. 2).

  The cold air blown obliquely forward and upward from the slit 16B circulates in the display chamber 6 below the shelf 27 and repeats circulation returning to the cooling chamber 9 from the lower cold air inlet 18. On the other hand, the cold air blown out from the slit 16 </ b> A is sucked up by the upper blower 22 and rises along the front surface of the door 7. Then, the air is sucked into the upper blower 22 from the upper cold air inlet 23, accelerated, and discharged from the upper cold air outlet 24 toward the front opening of the display chamber 6. The discharged cool air is repeatedly circulated from the lower cool air suction port 18 to the cooling chamber 9, thereby forming a cool air curtain at the front opening.

  The cold air leaking from the upper cold air inlet 23 circulates on the shelf 27 and travels toward the lower cold air inlet 18. By such cold air circulation, the cold air is circulated uniformly and substantially uniformly in the space above and below the shelf 28 in the display chamber 6 to be cooled satisfactorily. Further, when the salesperson takes out the product G, the door 7 is opened and taken out. At that time, a part of the cool air discharged from the lower cool air discharge port 13 leaks from the opening on the rear surface, but there is no problem as long as it is a short time.

  As described above, according to the present invention, in the open showcase 1 in which the front surface and the rear surface are opened and the rear surface is closed so as to be freely opened and closed, the cooler 11 is installed below the display chamber 6. Thus, the cool air can be smoothly circulated in the display chamber 6 for cooling.

  Further, a slit 16A that blows out the cool air upward toward the front side of the door 7 and a slit 16B that blows out the cool air diagonally forward and upward on the front side of the slit 16A are formed in the cover 14 that covers the lower cold air discharge port 13. Therefore, a part of the cool air can be discharged into the display chamber 6 from the lower rear portion, and the cooling effect in the display chamber 6 is improved.

  In this case, a vertical wall 8A is formed at the rear edge of the deck pan 8, and this vertical wall 8A protrudes slightly above the front end of the cover 14, so that the product G displayed on the deck pan 8 as shown in FIG. When the product rides on the front part of the cover 14, the product G is lifted by the vertical wall 8A, so that a gap is formed between the slit 16B and the product G. Accordingly, even in such a case, the disadvantage that the discharge of the cold air from the slit 16B is completely blocked is prevented.

It is sectional drawing of the open showcase of the Example of this invention. It is an enlarged view of the circle A part of FIG. It is a figure which shows the state which the goods got on the cover of the lower cold air discharge outlet of FIG.
