Has been. The glass plate 24 constitutes a surface on which a product is placed (a product placement surface 23A). The frame member 25 is processed by sheet metal, and a support portion 26 that supports the glass plate 24 is formed on the upper portion. The glass plate 24 is placed on the support portion 26 via a packing (not shown). The plan view of FIG. 4 shows a state in which the shelf 12 is viewed from above through the glass plate 24.

  And the air curtain guide is comprised in the front-end part of the shelf 12 of such a structure. Hereinafter, examples 1 to 4 will be described as embodiments of the air curtain guide.

  The air curtain guide 30 as the first embodiment includes a rear wall 34 attached to the front end portion 23 </ b> B of the shelf plate 23 constituting each shelf 12, and a guide constituent member 31. The rear wall 34 is a plate-like member configured to extend in the width direction of the shelf board 23 (shelf 12), and a mounting surface 34A bent backward at a predetermined angle at the lower end of the rear wall 34. Is configured. The attachment surface 34A is fixed to the lower surface of the front end portion of the shelf board 23, in this embodiment, to the lower surface of the front frame member 25 by screws.

  Further, in the present embodiment, as shown in FIG. 5, the rear wall 34 is provided with an inclination at a predetermined angle so that the lower end is in front of the upper end. As a result, the front surface 34B of the rear wall 34 is disposed at a predetermined angle and obliquely upward with respect to the product placement surface 23A of the shelf board 23. Therefore, a price rail 37 is formed on the front surface 34B of the rear wall 34 in the width direction of the shelf 12, and the product name, price, etc. of the product displayed on the product placement surface 23A of the shelf 12 on the price rail 37 are shown. The price card 38 made of paper or a resin sheet describing the above may be detachably held.

  As a result, even if the shelf plate 23 is installed to be inclined with the brackets 20 and 20 so that the front portion is low and the rear portion is high, the price card 38 is inclined upward with respect to the product placement surface 23A. Since it is provided on the front surface 34B of the rear wall 34 provided toward the front, the customer standing in front of the showcase 1 can easily see the price card 38. Thereby, the improvement of a product display effect can be aimed at.

  In the present embodiment, the rear wall 34 is provided at the front end of the shelf board 23 as a member constituting the air curtain guide 30. However, in the existing open showcase, the product is placed on the front end of the shelf board 23. A price rail that also serves as a guard and a shelf decoration is provided as a member for preventing the commodity displayed on the placement surface 23A from falling. Therefore, you may use the said guard etc. as a rear wall which comprises the air curtain guide 30 in this invention.

  On the other hand, the guide constituent member 31 includes a front wall 32 positioned in front of the rear wall 34 and a connecting portion 33 that connects the front wall 32 and the shelf plate 23. The front wall 32 is a plate-like member configured to extend in the width direction of the shelf board 23 (shelf 12) so as to face the rear wall 34. The connecting portion 33 is an arm configured to extend from the lower end portion (lower end rear surface) of the front wall 32 toward the shelf plate 23 (rear side). The front wall 32 and the front wall 32 are integrally provided at three locations in the substantially central portion.

  Each connecting portion 33 is configured in a linear shape or a relatively narrow plate shape, and the end portion (rear end) on the shelf plate 23 side is the lower surface of the shelf plate 23, in this embodiment, In a state of being attached to the lower surface of the mounting surface 34A of the rear wall 34, the rear wall 34 is detachably fixed with screws or the like. The shape and number of the connecting portions 33 are not limited to this. With such a configuration, a space (cold air flow path) 35 that is open vertically is formed between the front wall 32 and the rear wall 34 provided at the front end portion of the shelf board 23 so as not to disturb the air flow.

  Here, as shown in FIG. 5, the front wall 32 in the present embodiment is provided to be inclined at a predetermined angle so that the lower end 32B is located behind the upper end 32A. As a result, the front wall 32 is disposed at a predetermined angle with respect to the product placement surface 23 </ b> A of the shelf plate 23 in a diagonally downward direction.

  Therefore, in the air curtain guide 30 constituted by the front wall 32 and the rear wall 34 in this embodiment, the distance between the front wall 32 and the rear wall 34 is wide at the upper part and the lower part is narrow (the upper part of the space 35 is wide and the lower part is Narrow).

  At least the upper end of the front wall 32 of the air curtain guide 30 provided at the front end of the uppermost shelf 12 is below the front opening 5 from which the cool air is discharged and the front opening 5 from which the cool air is sucked. It is assumed that it is disposed so as to be located within a cold air discharge range configured by connecting the edge cold air suction port 17. Moreover, the air curtain guide 30 provided in each shelf 12 shall be arrange | positioned in the position corresponding to the downstream of the cold airflow which flows out from the air curtain guide 30 provided in an upper side.

  With this configuration, the air curtain guide 30 is located below the cool air discharge port 16 from the cool air discharge port 16 on the upper edge of the front opening 5 of the display chamber 11 toward the cool air suction port 17 on the lower edge of the opening 5. In this case, the front wall 32 and the rear wall 34 of the air curtain guide 30 configured at the front end of the uppermost shelf 12 are guided into the space (space 35) between these two walls. (The flow of cold air is indicated by the solid line arrow in FIG. 2).

  The cool air guided into the space (space 35) between the front wall 32 and the rear wall 34 of the air curtain guide 30 is rectified and flows out from the lower part of the space 35 in the process of flowing down. At this time, the distance between the front wall 32 and the rear wall 34 in this embodiment is larger in the air curtain guide 30 configured at the front end of the shelf because the upper portion is wider (the upper portion of the space 35 is wider). The cool air is guided and the cool air constituting the air curtain easily flows. Since the space between the front wall 32 and the rear wall 34 is configured such that the lower part is narrower than the upper part (the lower part of the space 35 is narrower), the distance becomes smaller in the process of flowing down. The rectification effect is improved.

  The cold air that has passed through the air curtain guide 30 configured at the front end portion of the uppermost shelf 12 flows into the air curtain guide 30 configured at the front end portion of the shelf 12 installed below the shelf. Sequentially, the cold air that has passed through the air curtain guide 30 formed at the front end of each shelf 12 returns to the lower duct 14 from the cold air inlet 17 at the lower edge of the front opening 5.

  As a result, a cold air curtain rectified by the air curtain guide 30 formed at the front end of each shelf 12 can be formed in the front opening 5. Accordingly, the cold air curtain is less likely to be disturbed by the flow of the outside air that comes into contact, and the leakage of the cold air staying (circulating) in the display chamber 11 can be effectively suppressed. Therefore, the cooling efficiency can be improved.

  In this embodiment, as shown in FIG. 5, both the front wall 32 and the rear wall 34 constituting the air curtain guide 30 are inclined with respect to the product placement surface 23 </ b> A of the shelf plate 23. The interval is configured such that the upper part is wide and the lower part is narrow. However, the present invention is not limited to this, and for example, the configuration shown in FIGS. 6 to 8 may be used.

  That is, in the configuration shown in FIG. 6, only the front wall 32 is inclined at a predetermined angle so that the lower end 32B is behind the upper end portion 32A, and the rear wall 36 corresponding to the rear wall 34 is It may be configured to stand substantially vertically to the product placement surface 23A and above the product placement surface 23A. Also by this, the space | interval of the front wall 32 and the rear wall 36 which comprise the air curtain guide 30 is comprised so that an upper part may be wide and a lower part may become narrow, and it can restrict | squeeze the cold airflow which passes similarly to the above, and a rectification effect Improvement can be realized.
