  The best mode for carrying out the open showcase according to the present invention will be described below based on the embodiments.

  An embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a partially broken side view of an open showcase in an embodiment of the present invention. FIG. 2 is an enlarged side view of the open showcase canopy. FIG. 3 is an enlarged side view of the canopy as in FIG. FIG. 4 is an enlarged side view of the canopy in a modification of the present invention.

  The open showcase 1 shown in FIG. 1 is installed mainly in stores that handle foods such as stores, supermarkets, and convenience stores, and is installed to display products in a cold or frozen state while keeping the products at a low temperature. In this embodiment, the overall height is configured to be about 1900 to 2000 mm so that a canopy 20 described later is positioned higher than the line of sight of the customer.

  In the refrigerator compartment 8 surrounded by the inner box 3 opened on the front side, a plurality of display shelves 7 for displaying products are installed in the vertical direction, and products (not shown) can be displayed on the bottom plate 11 provided at the bottom. Therefore, a large number of products can be placed. Hereinafter, in the description of the present embodiment, the open showcase 1 of FIG. 1 is faced, the front front side is the right side, the depth side is the left side, the opening side of the inner box 3 is the front side, and the obstruction is closed. The side will be described as the rear.

  The open showcase 1 includes an inner box 3 whose front side is opened, and an outer box 2 which is opened on the front side like the inner box 3 and is provided in the left-right direction so as to surround the inner box 3. The outer box 2 is composed of a heat insulating member made of a foamed urethane resin material and the like, and a surface plate such as a steel metal covering the front and back surfaces of the heat insulating member. A ventilation path 4 is formed between the outer box 2 and the inner box 3 to form a showcase body 34. A cooling device 5 and a blower 6 are provided in the ventilation path 4.

  A suction port 9 for taking air into the ventilation path 4 is formed at the lower part of the open showcase 1, and a cold air outlet 10 for cool air cooled by the cooling device 5 is formed at the upper part of the open showcase 1. ing. Therefore, by the operation of the blower 6, cold air cooled by the cooling device 5 is blown out from the cold air outlet 10 toward the suction inlet 9, and a cold air curtain 12 that closes the opening of the inner box 3 in front of the showcase 1 is provided. In addition to being formed, a part of the cold air in the air curtain 12 is supplied into the refrigerator compartment 8 so that the temperature can be kept low and placed on the display shelf 7 or the bottom plate 11 in the refrigerator compartment 8. Products (not shown) can be displayed in a refrigerated (frozen) state.

  A nosing 25 extending in the left-right width direction is extended in a substantially vertical direction at a front position of the blower outlet 10, and a rectifying plate 15 is substantially directed downward at a rear position of the cold air outlet 10. Extending in the vertical direction, the nodding 25 and the rectifying plate 15 assist the rectification of the air curtain 12 blown out from the cold air outlet 10. An illuminating device 14 such as a fluorescent lamp for illuminating the inside of the refrigerator compartment 8 is disposed behind the rectifying plate 15. Similarly, an illuminating device 13 such as a fluorescent lamp for illuminating commodities displayed on the display shelf 7 and the bottom plate 11 directly below is provided on the lower surface of the front end portion of each display shelf 7.

  A canopy 20 provided with canopy illumination such as a fluorescent lamp for illuminating the inside of the refrigerator compartment 8 in front is attached above the nosing 25 so as to be directed forward from the upper front end of the outer box 2.

  Next, details of the canopy 20 will be described.

  As shown in FIG. 2, the canopy 20 is made of a member such as a steel metal extending in the left-right width direction. Basically, the canopy 20 has a hollow box shape. A pair of a canopy body 20a having an upward horizontal surface V as an outer surface, and a front hanging portion 20b that curves from the front end of the canopy body 20a toward the front lower side and has a curved surface U and an inclined surface W as outer surfaces. It is a unit structure. The rear side of the canopy body 20a has a notch in the left-right width direction so as to contact the upper surface and the front end surface of the outer box 2, and the canopy body 20a and the outer box 2 are fixedly connected. In this way, it is fixed from above the outer box 2 with a screw or the like (not shown).

  On the outer surface of the canopy 20, a horizontal surface V, a curved surface U, and an inclined surface W are successively formed in order from the outer box 2 side toward the front. The horizontal plane V has a substantially planar shape that extends forward from the upper front end of the outer box 2, and a curved surface U that is a gently curved surface that gradually falls convexly toward the outside of the canopy 20 substantially flush with the horizontal plane V. It is formed. This curved surface U forms a continuous surface from the start point S that is the boundary with the horizontal plane V to the end point T that is the end of the curved surface U, and toward the refrigerator compartment 8 side of the open showcase 1 with this end point T as the boundary. Thus, an inclined surface W having a deflected surface extending downward is formed.

  By doing in this way, compared with the case where the canopy 20 is composed only of a curved surface, the curved surface U and the curved surface U can be further extended forward without lowering the arrangement position of the end point of the curved surface U. Since no step portion or the like is formed between the surface U and the horizontal plane V, the outer surface of the canopy 20 can be easily wiped and cleaned over the horizontal plane V formed substantially flush with the curved surface U.

  The inner surface (back surface) side of the canopy 20 will be described. The interior of the refrigerator compartment 8 extending in the left-right width direction is illuminated through sockets (not shown) screwed to the inner surface of the canopy 20 on both the left and right sides of the open showcase 1. A canopy illumination 26 such as a fluorescent lamp is provided. The canopy illumination 26 is protected by a protective member 27 surrounding the periphery thereof, and the canopy illumination 26 is arranged at a higher position than the horizontal line AA passing through the end point T. Further, a power supply wiring (not shown) connected to the canopy illumination 26 is provided on the rear side of the open showcase 1 by using the hollow internal space of the canopy 20 described above.

  Thus, the front drooping portion 20b that curves forwardly downward is formed in front of the canopy body 20a in the canopy 20, and the canopy illumination 26 is disposed on the inner surface side of the front drooping portion 20b, and the end point of the curved surface U By disposing T at a lower position than the canopy illumination 26, the front of the canopy illumination 26 is shielded from light by the front hanging portion 20b, that is, the curved surface U, so that dazzling of customers facing the open showcase 1 is reduced. Is done.

  In addition, an inclined surface W having a deflected surface that is continuous with the end point T and extends rearward and downward toward the refrigerator compartment 8 side of the open showcase 1 is formed. Therefore, the curved surface U and the inclined surface W allow the canopy 20 to The canopy illumination 26 disposed on the inner surface side can be formed so as to cover and protect from the outside of the open showcase 1.

  Next, the nosing 25 has a side view shape in which the upper part of the front surface is partially cut out, and the inside is hollow and extends in the left-right width direction, and the rear surface is partially opened for the screwing operation described later. Yes. A night cover (not shown) wound around a pivot shaft pivoted in the left-right direction is housed in the hollow interior of the nosing 25, and the front of the nosing 25 as needed, such as during non-business hours of the store. The night cover can be taken out from a slit (not shown) opened in the window. The nosing 25 is fixed by screwing the contact surface between the upper surface of the nodding 25 and the bottom surface of the canopy body 20a. The bracket 29, which is made of metal or the like and has a substantially T-shape in side view and extends in the left-right width direction, has an upper surface and a front surface of the bracket 29 that are connected to a bottom surface of the outer box 2 so It is brought into contact with the rear surface of the nosing 25 and fixed with screws or the like.

  The rectifying plate 15 is a steel plate or the like having a substantially L-shaped side view extending in the left-right width direction. The upper surface of the rectifying plate 15 and the lower surface of the inner box 3 are in contact with each other, and the contact surface is fixed with screws or the like. The In addition, an illuminating device 14 such as a fluorescent lamp having a socket in the lateral width direction in contact with the upper surface and the side surface is provided on the rear surface side of the current plate 15.

  In the vicinity of the cold air outlet 10, the ventilation path 4 composed of the rectifying plate 15 and the bracket 29 between the outer box 2 and the inner box 3 goes in the front-rear direction between the outer box 2 and the inner box 3, It is formed between the front surface of the current plate 15 and the rear surface of the bracket 29 in the vertical direction, and the cool air generated by the cooler 5 not shown in FIG. It blows out from the cold air blower outlet 10 which opens toward.

  In the embodiment configured as described above, since the curved surface U is formed on the outer surface of the front hanging portion 20b in the canopy 20, even if the outer surface is extended forward to attach the canopy illumination 26 forward, the canopy illumination 26 The curved surface U that is the outer surface of the front hanging portion 20b that covers the door is not disposed toward the customer side facing the open showcase 1, that is, the curved surface U does not face the line of sight from the customer. Since they are arranged substantially in parallel, there is less pressure on the customers facing the open showcase 1 and the product can be made more conspicuous than the open showcase 1.

  In particular, for the curved surface U, as shown in FIG. 3, the horizontal dimension X from the start point S to the end point T where the curved surface U is formed is longer than the vertical dimension Y from the start point S to the end point T. As a result, the field of view toward the rear upper side of the open showcase 1 is expanded, and the reflected light K ′ from the curved surface U of the indoor light K is mainly diffusely reflected upward of the open showcase 1. As a result, dazzling of customers facing the open showcase 1 is reduced. Moreover, since the starting point S is arranged behind the canopy illumination 26, the curved surface U is more inclined in the front-rear direction, so that it is difficult to face the customer.

  Note that the curved surface U not only reflects the reflected light K ′, but also when an indoor air conditioner (not shown) is installed above the open showcase 1, for example, the open showcase 1 Since the blown air sent out rearward and downward is blocked by the curved surface U and dispersed, the blown air can be prevented from being mixed into the cold air blown out from the cold air outlet 10.

  Further, a convex curved surface U is formed outwardly on the outer surface of the canopy 20 of the open showcase 1 of the present embodiment so that the outside air J above the open showcase 1 is kept away from the cold air outlet 10 and turns around. Therefore, the flow of the air curtain 12 caused by the cold air blown out from the cold air outlet 10 prevents the outside air J above the open showcase 1 having a relatively high temperature from being mixed into the cold air, and the inside of the refrigerator compartment 8 is made efficient. Can be kept cool.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  In the above embodiment, the gently curved surface U is formed from the start point S to the end point T. For example, as a modified example, the curved surface U ′ shown in FIG. 4 has a radius R centered on the center point P. It may be formed by a circular arc. According to this feature, the curved surface U ′ can be easily formed, and since the curvature radius is not changed, the strength of the canopy 20 can be kept uniform. Since it is an arc-shaped curved surface, it gives customers a unique aesthetic due to their elegant smartness.

  Further, the present invention is not limited to an open showcase having an overall height of about 1900 to 2000 mm, and includes all open showcases used for displaying frozen foods, fresh foods and the like in food stores such as supermarkets, convenience stores, and department stores.

It is a partially broken side view of the open showcase in the Example of this invention. It is a canopy expansion side view of an open showcase. It is a canopy expansion side view like FIG. It is a canopy expansion side view in a modification.
