Summary of the Invention

Problems to be Solved by the Invention

[0004] The present disclosure provides an open showcase that can easily drain condensed water.

Means for Solving the Problems

[0005] The open showcase in the present disclosure includes a display chamber and side plates that partition the display chamber and the outside in the width direction. The side plates have a transparent flat window plate and a frame portion that supports the window plate. The frame portion has an inner plate facing the display chamber and having a first window portion where the window plate is disposed, an outer plate arranged on the outer side in the width direction with respect to the inner plate and having a second window portion where the window plate is disposed, and a trim member provided along a first lower edge that is the lower edge of the first window portion and a second lower edge that is the lower edge of the second window portion. The trim member has a support recess that is recessed downward to support the window plate and whose bottom surface is located above the first lower edge and below the second lower edge, and a drain hole that communicates the inside of the support recess with the display chamber.

Effects of the Invention

[0006] In the open showcase according to the present disclosure, since the window plate is supported by the support recess whose bottom surface is located above the first lower edge, the condensed water flowing into the support recess through the window plate can be easily directly flowed into the display chamber from the drain hole provided in the support recess. Therefore, the condensed water can be easily drained. Further, since the first lower edge is located below the second lower edge and the bottom surface of the support recess is located below the second lower edge, the range in which the display chamber can be visually recognized through the window plate is less likely to be narrowed by the support recess. Therefore, it is easy to ensure the visibility of the display chamber through the window plate.

Modes for Carrying Out the Invention

[0008] (Knowledge, etc. underlying the present disclosure) When the inventors arrived at the idea of the present disclosure, in the technical field of open showcases, there was a technique for draining condensed water generated on a window plate or the like through a display chamber. For example, Patent Document 1 describes that condensed water generated on a transparent glass is flowed forward through a groove recess of a glass receiving frame and then flowed into the inside of the storage through a drain hole of a cap attached to the front end of the transparent glass. However, in the configuration of draining the condensed water to the inside of the storage after flowing it to the front end of the glass receiving frame as in Patent Document 1, when the amount of condensed water generated on the transparent glass or the like increases, the treatment of the condensed water cannot keep up, and the inventors have discovered the problem that the condensed water may flow out to the outside of the open showcase. In order to solve this problem, the inventors have come to configure the subject matter of the present disclosure. Therefore, the present disclosure provides an open showcase that can easily drain condensed water.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, a more detailed description than necessary may be omitted. For example, a detailed description of well-known matters or a redundant description of substantially the same configuration may be omitted. This is to avoid making the following description overly redundant and to facilitate the understanding of those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0010] (Embodiment 1) Hereinafter, Embodiment 1 will be described with reference to the drawings. [1-1. Configuration] [1-1-1. Overall Configuration] FIG. 1 is a perspective view of an open showcase 1 according to Embodiment 1. The open showcase 1 is disposed, for example, on the floor of a store such as a supermarket or a convenience store, and displays items such as beverages and foods, which are objects to be displayed, in a refrigerated state. The open showcase 1 is a so-called open-type showcase.

[0011] The open showcase 1 has a substantially box-shaped case body 11 with an opening at the front for taking items in and out. Hereinafter, with the opening direction of the case body 11 in the horizontal direction being the front, the direction orthogonal to the front-rear direction in the horizontal direction is referred to as the width direction or the left-right direction. In the width direction, the side closer to the center of the open showcase 1 is referred to as the inner side in the width direction, and the side farther from the center of the open showcase 1 is referred to as the outer side in the width direction.

[0012] Inside the case body 11, a display chamber 12, which is a space for displaying items, is provided. Inside the display chamber 12, a plurality of display shelves 13 on which items can be placed are provided. The temperature of the display chamber 12 is set to the refrigeration temperature range or the freezing temperature range, and is lower than the room temperature of the installation location where the open showcase 1 is provided. For this reason, the display chamber 12 is provided with a drainage path (not shown) for draining the dew condensation water in the display chamber 12. The dew condensation water flowing into the display chamber 12 is configured to be drained to the outside through the drainage path.

[0013] At the bottom of the display chamber 12, a deck pan (not shown) is provided. In the case body 11, below the deck pan, a cooling fan (not shown), a cooler, etc. for cooling the display chamber 12 are stored.

[0014] In the open showcase 1, a pedestal portion 20 is provided below the case body 11. Inside the pedestal portion 20, an electric box (not shown) etc. are arranged. The pedestal portion 20 is provided with a kick plate 21 that covers the lower part of the case body 11, that is, the inside of the pedestal portion 20, from the front. The kick plate 21 is a member mainly composed of a metal plate. In the present embodiment, inside the pedestal portion 20, a refrigerant pipe connecting the above-described cooler and the outdoor unit, and a drainage path such as a drain hose for draining the dew condensation water of the display chamber 12 are arranged. Note that, unlike the present embodiment, when the open showcase 1 is not connected to the outdoor unit, a compressor, a condenser, etc. may be provided inside the pedestal portion 20.

[0015] At both ends in the width direction of the open showcase 1, a pair of side plates 30 are provided. The side plates 30 are plate-shaped structures orthogonal to the width direction. The side plates 30 partition the display chamber 12 and the outside of the open showcase 1 in the width direction.

[0016] [1-1-2. Configuration of Side Plate] FIG. 2 is a view showing the side plate 30 as viewed from the inner side in the width direction. FIG. 3 is a view showing the side plate 30 as viewed from the outer side in the width direction. Since one of the pair of side plates 30 has a configuration in which the left and right of the other are reversed, hereinafter, only the side plate 30 located on the right side when the open showcase 1 is viewed from the front side will be described.

[0017] The side plate 30 includes a transparent plate-shaped window plate 31. In the present embodiment, the window plate 31 is a pair glass having a layer of air or an enclosed gas between two glass plates, and is formed in a rectangular shape. As shown in FIG. 3, the window plate 31 is disposed at a position covering the display chamber 12 from the outer side in the width direction. Therefore, the inside of the display chamber 12 can be visually recognized from the outside of the open showcase 1 through the window plate 31.

[0018] The side plate 30 includes a frame portion 40 that supports the window plate 31. As shown in FIGS. 2 and 3, the frame portion 40 includes an inner plate 41 and an outer plate 42. The inner plate 41 and the outer plate 42 are plate-shaped members each formed of an iron sheet metal. The inner plate 41 and the outer plate 42 are parallel to each other and are arranged in a direction orthogonal to the width direction. The inner plate 41 is arranged on the inner side in the width direction of the outer plate 42 and faces the inside of the display chamber 12. The outer plate 42 faces the space outside the open showcase 1.

[0019] As shown in FIG. 2, a first window portion 43 is formed in the inner plate 41. The first window portion 43 is a rectangular notch that opens forward. The window plate 31 is disposed in the first window portion 43. In the inner plate 41, a first lower edge 45, which is the lower edge of the first window portion 43, is parallel to the front-rear direction. In the inner plate 41, a first rear edge 45A, which is the rear edge of the first window portion 43, is parallel to the vertical direction. In the inner plate 41, a first upper edge 45B, which is the upper edge of the first window portion 43, is parallel to the front-rear direction.

[0020] As shown in FIG. 3, a second window portion 44 is formed in the outer plate 42. The second window portion 44 is a rectangular notch that opens forward. A window plate 31 is disposed in the second window portion 44. In the outer plate 42, a second lower edge 46, which is the lower edge of the second window portion 44, is parallel to the front-rear direction. In the outer plate 42, a second rear edge 46A, which is the rear edge of the second window portion 44, is parallel to the vertical direction. In the outer plate 42, a second upper edge 46B, which is the upper edge of the second window portion 44, is parallel to the front-rear direction.

[0021] As shown in FIGS. 2 and 3, the frame portion 40 includes a lower trim member 50, a rear trim member 50A, and an upper trim member 50B. The lower trim member 50 is a member provided along the first lower edge 45 and the second lower edge 46. The lower trim member 50 is provided with its longitudinal direction being the front-rear direction. The rear trim member 50A is a member provided along the first rear edge 45A and the second rear edge 46A. The rear trim member 50A is provided with its longitudinal direction being the vertical direction. The upper trim member 50B is a member provided along the first upper edge 45B and the second upper edge 46B. The upper trim member 50B is provided with its longitudinal direction being the front-rear direction. In the present embodiment, each of the trim members 50, 50A, and 50B is made of PVC (Polyvinyl-Chloride) resin. The lower trim member 50 corresponds to the "trim member" in the present disclosure.

[0022] FIG. 4 is a cross-sectional view taken along the IV-IV section of FIG. 2, and is a cross-sectional view when the lower trim member 50 is cut along a cross-section orthogonal to the front-rear direction, which is the longitudinal direction of the lower trim member 50. In the figure, reference numeral D1 indicates a direction toward the inner side in the width direction, and reference numeral D2 indicates a direction toward the outer side in the width direction. As shown in FIG. 4, a foamed heat insulating material 47 is filled between the inner plate 41 and the outer plate 42.

[0023] As shown in FIG. 4, a first insertion portion 51 is formed in the lower trim member 50. The first insertion portion 51 has a first inner half portion 53 protruding downward and a first outer half portion 55 protruding downward while being spaced apart from the first inner half portion 53 outward in the width direction. Further, a first groove portion 57, which is a groove between the first inner half portion 53 and the first outer half portion 55, is formed in the first insertion portion 51. As shown in FIG. 4, the first groove portion 57 is a groove opening downward. The first lower edge 45 of the first window portion 43 in the inner plate 41 is inserted into the first groove portion 57 from below.

[0024] A second insertion portion 52 is formed in the lower trim member 50. The second insertion portion 52 has a second inner half portion 54 protruding downward and a second outer half portion 56 protruding downward while being spaced apart from the second inner half portion 54 outward in the width direction. Further, a second groove portion 58, which is a groove between the second inner half portion 54 and the second outer half portion 56, is formed in the second insertion portion 52. The second groove portion 58 is a groove opening downward. The second lower edge 46 of the second window portion 44 in the outer plate 42 is inserted into the second groove portion 58 from below.

[0025] That is, the lower trim member 50 is provided so as to straddle the inner plate 41 and the outer plate 42 arranged at intervals in the width direction. In the present embodiment, in the first insertion portion 51, the first outer half portion 55 inserted inside the inner plate 41 and the outer plate 42 extends below the first inner half portion 53 arranged outside the inner plate 41 and the outer plate 42 in the width direction. Further, in the second insertion portion 52, the second inner half portion 54 inserted inside the inner plate 41 and the outer plate 42 extends below the second outer half portion 56 arranged outside the inner plate 41 and the outer plate 42. Therefore, by inserting the first outer half portion 55 and the second inner half portion 54 between the inner plate 41 and the outer plate 42 arranged in the width direction from above, the lower trim member 50 can be easily attached to the inner plate 41 and the outer plate 42.

[0026] In the lower trim member 50, a groove-shaped support recess 60 that is recessed downward is formed. The support recess 60 is formed in the lower trim member 50 over a region that is approximately half of the inner side in the width direction. The lower end 33 of the window plate 31 is inserted into the support recess 60. Thereby, the support recess 60 supports the window plate 31. In the present embodiment, the support recess 60 is recessed in a rectangular shape in the cross section of FIG. 4. A horizontal planar bottom surface portion 61 is formed in the support recess 60. The bottom surface portion 61 vertically partitions the inside and outside of the support recess 60. Also, at the inner end in the width direction of the bottom surface portion 61, the above-described first insertion portion 51 is formed downward.

[0027] An inner side wall portion 64 that rises upward is formed at the inner end in the width direction of the bottom surface portion 61. An outer side wall portion 67 that rises upward is formed at the outer end in the width direction of the bottom surface portion 61. The inner side wall portion 64 and the outer side wall portion 67 each partition the inside and outside of the support recess 60 in the width direction. Also, in the lower trim member 50, a hollow portion 59 formed in a substantially rectangular cross section is formed on the outer side in the width direction of the outer side wall portion 67. At the outer end in the width direction of the hollow portion 59, the above-described second insertion portion 52 is formed downward.

[0028] On the upper surface 62 that faces upward in the bottom surface portion 61, a first rib 63 that protrudes upward is formed. In the present embodiment, two first ribs 63 are provided side by side in the width direction on the upper surface 62. Also, the first rib 63 has a rectangular cross section. In the inner side wall portion 64, on the first side surface 65 that faces the outer side in the width direction, a second rib 66 that protrudes toward the outer side in the width direction is formed. In the outer side wall portion 67, on the second side surface 68 that faces the inner side in the width direction, a third rib 69 that protrudes toward the inner side in the width direction is formed. The second rib 66 and the third rib 69 have a substantially rectangular cross section, and the upper corners of their respective tips are chamfered obliquely. The upper surface 62, the first side surface 65, and the second side surface 68 in the present embodiment respectively correspond to the "inner surface of the support recess". That is, each rib 63, 66, 69 is formed on the inner surface of the support recess 60. The first rib 63, the second rib 66, and the third rib 69 in the present embodiment respectively correspond to the "rib".

[0029] As shown in Fig. 4, the support recess 60 holds the window plate 31 by bringing the tips of the ribs 63, 66, and 69 into contact with the window plate 31. Therefore, a gap is formed between the inner surfaces 62, 65, 68 of the support recess 60 and the window plate 31. Specifically, the upper surface 62 of the bottom surface portion 61 and the lower end 33 of the window plate 31 are vertically separated by the first rib 63. The first side surface 65 of the inner side wall portion 64 and the inner side surface 35 of the window plate 31 are separated in the width direction by the second rib 66. The second side surface 68 of the outer side wall portion 67 and the outer side surface 37 of the window plate 31 are separated in the width direction by the third rib 69. The inner side surface 35 is the surface of the window plate 31 facing the inner side in the width direction. The outer side surface 37 is the surface of the window plate 31 facing the outer side in the width direction.

[0030] Fig. 5 is a cross-sectional view taken along the V-V cross-section of Fig. 2, and is a cross-sectional view when the lower trim member 50 is cut along a cross-section orthogonal to the front-rear direction, which is the longitudinal direction of the lower trim member 50, at a position where the drain hole 70 is provided. As shown in Fig. 5, the drain hole 70 is a hole penetrating the inner side wall portion 64 in the width direction. In the present embodiment, the lower end of the drain hole 70 is formed flush with the upper surface 62 of the bottom surface portion 61. Further, in the present embodiment, the drain holes 70 are formed at two locations of the lower trim member 50 in the front-rear direction (see Fig. 2).

[0031] As shown in Figs. 4 and 5, the upper surface 62 of the bottom surface portion 61 of the support recess 60 is located above the first lower edge 45. Therefore, the drain hole 70 is located above the first lower edge 45, and the inside of the support recess 60 is communicated with the inside of the display chamber 12 in the width direction through the drain hole 70. The upper surface 62 of the bottom surface portion 61 in the present embodiment is an example of the "bottom surface of the support recess".

[0032] Furthermore, the first lower edge 45 of the inner plate 41 is located below the second lower edge 46 of the outer plate 42. Also, the upper surface 62 of the bottom surface portion 61 is located below the second lower edge 46. That is, at least a part of the support recess 60 is formed below the second lower edge 46.

[0033] Thus, in this embodiment, instead of raising the position where the support recess 60 is provided, the first lower edge 45 is provided at a position lower than the second lower edge 46, and the upper surface 62 is provided at the height between the first lower edge 45 and the second lower edge 46, so that the drain hole 70 is formed at a position higher than the first lower edge 45. Thereby, drainage can be easily performed from the drain hole 70 located above the first lower edge 45, and it is suppressed that the range where the display chamber 12 can be visually recognized through the window plate 31 is narrowed by the support recess 60. Further, since the heights of the first lower edge 45 and the second lower edge 46 are different, when inserting the lower edges 45 and 46 into the respective insertion portions 51 and 52, it is difficult to misalign the direction of the lower trim member 50.

[0034] Also, as shown in FIG. 5, the lower trim member 50 is formed with a first water passage port 71, a second water passage port 73, and a third water passage port 75. The first water passage port 71 is an opening formed in the first rib 63. The first water passage port 71 penetrates the first rib 63 in the width direction. In this embodiment, the lower end of the first water passage port 71 is flush with the upper surface 62 of the bottom surface portion 61. The second water passage port 73 is an opening formed in the second rib 66. The second water passage port 73 penetrates the second rib 66 vertically. The third water passage port 75 is an opening formed in the third rib 69. The third water passage port 75 penetrates the third rib 69 vertically. Therefore, dew condensation water can easily pass through the respective ribs 63, 66, and 69 through the respective water passage ports 71, 73, and 75.

[0035] Also, as shown in FIG. 5, the respective water passage ports 71, 73, 75 and the drain hole 70 open in the same cross section orthogonal to the front-rear direction. In other words, in the front-rear direction which is the longitudinal direction of the lower trim member 50, at least a part of the positions occupied by the respective water passage ports 71, 73, 75 overlaps with the position occupied by the drain hole 70. Thereby, the dew condensation water that has passed through the respective ribs 63, 66, 69 through the water passage ports 71, 73, 75 is easily drained from the drain hole 70 as it is.

[0036] In addition, in the present embodiment, the lower trim member 50 is manufactured by extrusion molding in the longitudinal direction of the lower trim member 50, that is, in the front-rear direction. Further, the drain holes 70 and the water passage openings 71, 73, 75 are formed by processing after extrusion molding. In the present embodiment, the rear trim member 50A and the upper trim member 50B are designed such that the cross-sectional shape in a cross-section orthogonal to their respective longitudinal directions is the same as the cross-sectional shape of the lower trim member 50 shown in FIG. 4. For this reason, each of the trim members 50, 50A, 50B can be manufactured by extrusion molding using the same mold, and it is easy to reduce the cost of manufacturing each of the trim members 50, 50A, 50B.

[0037] [1-2. Operation] Regarding the open showcase 1 configured as described above, its operation will be described below.

[0038] During the operation of the open showcase 1, the air inside the display chamber 12 is cooled. As described above, since the display chamber 12 is open forward toward the outside of the case main body 11, the air outside the case main body 11 may enter the display chamber 12 beyond the air curtain. In this case, the air that has flowed into the display chamber 12 is cooled, and dew water may be generated in each part of the display chamber 12.

[0039] In the display chamber 12, when dew water is generated on the inner surface 35 of the window plate 31, the dew water flows downward along the inner surface 35 and reaches the lower trim member 50. As described above, in the support recess 60 that supports the window plate 31 in the lower trim member 50, a second rib 66 is formed that separates the inner surface 35 of the window plate 31 and the first side surface 65 that is the inner surface of the support recess 60. For this reason, the dew water that has reached the lower trim member 50 easily flows into the upper surface of the second rib 66 located inside the support recess 60 through the gap between the inner surface 35 and the first side surface 65.

[0040] Thereafter, the condensed water flows back and forth on the upper surface of the second rib 66 and reaches the second water passage port 73. The condensed water flows downward through the second water passage port 73 and passes through the second rib 66. Thereafter, the condensed water reaches the upper surface 62 of the bottom surface portion 61 and is drained into the inside of the display chamber 12 through the drain hole 70 formed in the inner side wall portion 64. In the present embodiment, since at least a part of the position occupied by the second water passage port 73 in the front-rear direction overlaps with the position occupied by the drain hole 70 in the front-rear direction, the condensed water that has reached the upper surface 62 is easily drained from the drain hole 70 as it is.

[0041] Further, the window plate 31 is cooled by the air in the display chamber 12. For this reason, condensed water may be generated on the outer surface 37 of the window plate 31. In this case, the condensed water flows downward along the outer surface 37 and reaches the lower trim member 50. As described above, a third rib 69 that separates the outer surface 37 of the window plate 31 and the second side surface 68 that is the inner surface of the support recess 60 is formed in the support recess 60 of the lower trim member 50 that supports the window plate 31. For this reason, the condensed water that has reached the lower trim member 50 easily flows into the upper surface of the third rib 69 located inside the support recess 60 through the gap between the outer surface 37 and the second side surface 68.

[0042] Thereafter, the condensed water flows back and forth on the upper surface of the third rib 69 and reaches the third water passage port 75. The condensed water flows downward through the third water passage port 75 and passes through the third rib 69. Thereafter, the condensed water reaches the upper surface 62 of the bottom surface portion 61. As described above, a first rib 63 that vertically separates the upper surface 62 of the bottom surface portion 61 and the lower end 33 of the window plate 31 is formed in the support recess 60. Further, a first water passage port 71 penetrating left and right is formed in the first rib 63. For this reason, the condensed water that has reached the upper surface 62 flows inward in the width direction through the first water passage port 71, passes through the window plate 31 and the first rib 63, reaches the drain hole 70, and is drained into the display chamber 12. In the present embodiment, the positions occupied by the third water passage port 75, the first water passage port 71, and the drain hole 70 in the front-rear direction at least partially overlap with each other. For this reason, the condensed water that has reached the upper surface 62 is easily drained from the drain hole 70 as it is.

[0043] The condensed water drained into the display chamber 12 is drained to the outside of the open showcase 1 through a drainage path (not shown). Thereby, the condensed water generated on the side plate 30 can be easily drained without leaking to the outside of the open showcase 1.

[0044] Also, as described above, in the present embodiment, each of the trim members 50, 50A, and 50B provided across the inner plate 41 and the outer plate 42 is made of PVC resin. Therefore, even when the display chamber 12 and the inner plate 41 are at a low temperature, the trim member 50 is difficult to be cooled. Further, the outer plate 42 is difficult to be cooled through the trim member 50. For this reason, the generation of condensed water on the trim member 50 and the outer plate 42 can be suppressed.

[0045] [1-3. Effects, etc.] As described above, in the present embodiment, the open showcase 1 includes a display chamber 12 and a side plate 30 that partitions the display chamber 12 and the outside in the width direction. The side plate 30 has a transparent flat window plate 31 and a frame portion 40 that supports the window plate 31. The frame portion 40 faces the display chamber 12 and has an inner plate 41 in which a first window portion 43 where the window plate 31 is disposed is formed, and an outer plate 42 that is arranged outside the inner plate 41 in the width direction and in which a second window portion 44 where the window plate 31 is disposed is formed, and a lower trim member 50 provided along a first lower edge 45 that is the lower edge of the first window portion 43 and a second lower edge 46 that is the lower edge of the second window portion 44. The lower trim member 50 has a support recess 60 that is recessed downward to support the window plate 31 and in which an upper surface 62 of a bottom surface portion 61 is located above the first lower edge 45 and below the second lower edge 46, and a drainage hole 70 that communicates the inside of the support recess 60 with the display chamber 12. Thereby, since the window plate 31 is supported by the support recess 60 in which the upper surface 62 of the bottom surface portion 61 is located above the first lower edge 45, the condensed water flowing into the support recess 60 along the window plate 31 can be easily directly flowed from the drainage hole 70 provided in the support recess 60 into the display chamber 12 without being blocked by the inner plate 41. Further, since the first lower edge 45 is located below the second lower edge 46 and the upper surface 62 which is the bottom surface of the support recess 60 is located below the second lower edge 46, the range in which the display chamber 12 can be visually recognized through the window plate 31 is not easily narrowed by the support recess 60. Therefore, it is easy to ensure the visibility of the display chamber 12 through the window plate 31. As described above, in the present embodiment, the trim members 50, 50A, 50B attached to the respective edges 45, 45A, 45B, 46, 46A, 46B of the respective window portions 43, 44 are formed in the same cross-sectional shape. For this reason, the range in which the display chamber 12 can be visually recognized through the window plate 31 is not easily narrowed by the support recesses 60 of the trim members 50, 50A, 50B, so that it is easier to further ensure the visibility of the display chamber 12 through the window plate 31.

[0046] As in the present embodiment, the lower trim member 50 may be made of resin and may be configured to be provided across the inner plate 41 and the outer plate 42. Thereby, by providing the lower trim member 50 having a smaller thermal conductivity than a member made of metal or the like across the inner plate 41 and the outer plate 42, it is possible to suppress the heat of the outer plate 42 from being taken away by the lower trim member 50 to the inner plate 41. Further, a decrease in the temperature of the lower trim member 50 is also suppressed. For this reason, it is possible to suppress the generation of condensed water on the outer plate 42 and the lower trim member 50, and it is easier to suppress the condensed water from leaking to the outside of the open showcase 1. As described above, in the present embodiment, the trim members 50, 50A, 50B attached to the respective edges 45, 45A, 45B, 46, 46A, 46B of the respective window portions 43, 44 are both made of resin. For this reason, by providing the resin trim members 50, 50A, 50B having a smaller thermal conductivity than a member made of metal or the like across the inner plate 41 and the outer plate 42, it is possible to suppress the heat of the outer plate 42 from being taken away by the trim members 50, 50A, 50B to the inner plate 41. Further, since a decrease in the temperature of the trim members 50, 50A, 50B is also suppressed, it is possible to suppress the generation of condensed water on the outer plate 42 and the respective trim members 50, 50A, 50B, and it is easier to suppress the condensed water from leaking to the outside of the open showcase 1.

[0047] As in this embodiment, ribs 63, 66, and 69 that separate the window plate 31 from the upper surface 62, the first side surface 65, and the second side surface 68, which are the inner surfaces of the support recess 60, are formed in the support recess 60, and water passage openings 71, 73, and 75 for flowing the condensed water to the drain hole 70 are formed in the ribs 63, 66, and 69. This may be the configuration. Thereby, the condensed water generated on the window plate 31 easily flows into the inside of the support recess 60. Further, the water passage openings 71, 73, and 75 make it easy to flow the condensed water that has flowed into the inside of the support recess 60 toward the drain hole 70. Therefore, the condensed water can be easily drained.

[0048] As in this embodiment, in the longitudinal direction of the lower trim member 50, the positions occupied by the water passage openings 71, 73, and 75 may be configured such that at least a part thereof overlaps with the position occupied by the drain hole 70. Thereby, the condensed water that has flowed through the water passage openings 71, 73, and 75 easily flows into the drain hole 70. Therefore, the condensed water can be easily drained.

[0049] As in this embodiment, the lower trim member 50 is provided with a first insertion portion 51 in which a first groove portion 57 into which the first lower edge 45 is inserted is formed, and a second insertion portion 52 in which a second groove portion 58 into which the second lower edge 46 is inserted is formed. In the first insertion portion 51, the first outer half portion 55 on the outer side in the width direction with respect to the first groove portion 57 extends downward more than the first inner half portion 53 on the inner side in the width direction with respect to the first groove portion 57. In the second insertion portion 52, the second inner half portion 54 on the inner side in the width direction with respect to the second groove portion 58 extends downward more than the second outer half portion 56 on the outer side in the width direction with respect to the second groove portion 58. This may be the configuration. Thereby, it becomes easier to attach the lower trim member 50 to the inner plate 41 and the outer plate 42. Therefore, the open showcase 1 can be easily manufactured. In particular, in this embodiment, the first lower edge 45 inserted into the first insertion portion 51 and the second lower edge 46 inserted into the second insertion portion 52 have different heights. Therefore, it is difficult to misalign the orientation of the lower trim member 50 when attaching the lower trim member 50 to the inner plate 41 and the outer plate 42.

[0050] As in the present embodiment, the lower trim member 50 may be configured such that a plurality of drain holes 70 are formed therein. Thereby, even when a large amount of dew condensation water is generated on the window plate 31, it can be easily drained appropriately.

[0051] (Other embodiments) As described above, as an example of the technology disclosed in the present application, Embodiment 1 has been described. However, the technology in the present disclosure is not limited thereto, and can also be applied to embodiments in which changes, replacements, additions, omissions, etc. are made. Further, it is also possible to combine the respective constituent elements described in Embodiment 1 above to form a new embodiment. Therefore, other embodiments will be exemplified below.

[0052] In the above embodiment, a double-glass has been described as an example of the window plate 31. The window plate 31 may be any transparent plate-like member. Therefore, the window plate 31 is not limited to a double-glass. For example, the window plate 31 may be a single sheet of plate glass, or may be a multi-layer glass including a plurality of sheets of plate glass. Further, the window plate 31 may be a vacuum glass having a vacuum layer between two sheets of plate glass.

[0053] In the above embodiment, it has been described that the drain holes 70 are provided at two positions in the front-rear direction which is the longitudinal direction in the lower trim member 50, but this is an example. The drain holes 70 may be provided at three or more positions on the lower trim member 50 in the front-rear direction, or may be provided at one position. However, by providing the drain holes 70 at two positions as in Embodiment 1, the post-extrusion processing can be reduced compared to the case where they are provided at three or more positions, and the drainage can be made easier compared to the case where they are provided at only one position.

[0054] In the above-described embodiment, it has been described that the support recess 60 is provided with the first rib 63, the second rib 66, and the third rib 69, but this is merely an example. For example, the second rib 66 that separates the first side surface 65, which is the inner surface on the inner side in the width direction of the support recess 60, from the inner side surface 35 of the window plate 31 may not be provided. In this case, since the window plate 31 is supported by the support recess 60 with the inner side surface 35 in contact with the first side surface 65 of the support recess 60, the condensed water flowing along the inner side surface 35 is less likely to flow into the support recess 60. However, since the inner side surface 35 faces the display chamber 12, the condensed water that has not flowed into the support recess 60 from the inner side surface 35 can flow into the display chamber 12 along the outer surface of the support recess 60 without passing through the support recess 60. Therefore, even if the second rib 66 is not provided, the condensed water generated on the inner side surface 35 can be drained. However, by providing the second rib 66 as in the first embodiment, the condensed water generated on the inner side surface 35 can be concentrated and drained from the drain hole 70 into the display chamber 12, so it is easier to limit the range where the condensed water flows out from the lower trim member 50, and it is easier to make the drainage smoother.

[0055] In the above-described embodiment, it has been described that each of the trim members 50, 50A, and 50B is made of PVC resin, but this is merely an example. Each of the trim members 50, 50A, and 50B may be made of a resin other than PVC resin. For example, each of the trim members 50, 50A, and 50B may be made of polypropylene or the like.

[0056] Note that the above-described embodiment is for exemplifying the technology in the present disclosure, and various changes, replacements, additions, omissions, etc. can be made within the scope of the claims or the equivalent scope thereof.

[0057] (Supplementary Note) From the description of the above embodiments, the following technology is disclosed.

[0058] (TECHNOLOGY 1) An open showcase comprising a display room and side plates partitioning the display room and the outside in the width direction, the side plates having a transparent flat window plate and a frame portion supporting the window plate, the frame portion facing the display room and having an inner plate formed with a first window portion where the window plate is disposed, an outer plate arranged on the outer side in the width direction with respect to the inner plate and formed with a second window portion where the window plate is disposed, and a trim member provided along a first lower edge which is the lower edge of the first window portion and a second lower edge which is the lower edge of the second window portion, the trim member having a support recess recessed downward to support the window plate and having a bottom surface positioned above the first lower edge and below the second lower edge, and a drain hole communicating the inside of the support recess and the display room. Thus, since the window plate is supported by the support recess having a bottom surface positioned above the first lower edge, dew condensation water flowing into the support recess along the window plate can be easily directly drained from the drain hole provided in the support recess into the display room. Therefore, the dew condensation water can be easily drained. Also, since the first lower edge is positioned below the second lower edge and the bottom surface of the support recess is positioned below the second lower edge, the range in which the display room can be visually recognized through the window plate is less likely to be narrowed by the support recess. Therefore, it is easy to ensure the visibility of the display room through the window plate.

[0059] (TECHNOLOGY 2) The open showcase according to TECHNOLOGY 1, wherein the trim member is made of resin and is provided across the inner plate and the outer plate. Thus, by providing a resin-made trim member having a lower thermal conductivity than a member made of metal or the like across the inner plate and the outer plate, it is possible to suppress the heat of the outer plate from being taken away by the trim member and transferred to the inner plate. Also, a decrease in the temperature of the trim member is suppressed. Therefore, it is possible to suppress the generation of dew condensation water on the outer plate and the trim member, and it is easy to suppress the leakage of dew condensation water to the outside of the open showcase.

[0060] (TECHNOLOGY 3) The open showcase according to TECHNOLOGY 1 or 2, wherein ribs for separating the window plate from the inner surface of the support recess are formed in the support recess, and water passage openings for flowing dew condensation water to the drain hole are formed in the ribs. As a result, the condensed water generated on the window plate is likely to flow into the inside of the support recess. Further, the water passage port makes it easier for the condensed water flowing into the inside of the support recess to flow toward the drain hole. Therefore, the condensed water can be easily drained.

[0061] (TECHNOLOGY 4) In the longitudinal direction of the trim member, in the open showcase according to TECHNOLOGY 3, at least a part of the position occupied by the water passage port overlaps with the position occupied by the drain hole. As a result, the condensed water flowing through the water passage port is likely to flow into the drain hole. Therefore, the condensed water can be easily drained.

[0062] (TECHNOLOGY 5) The trim member is provided with a first insertion portion in which a first groove portion into which the first lower edge is inserted is formed, and a second insertion portion in which a second groove portion into which the second lower edge is inserted is formed. In the first insertion portion, a first outer half portion on the outer side in the width direction with reference to the first groove portion extends downward more than a first inner half portion on the inner side in the width direction with reference to the first groove portion. In the second insertion portion, a second inner half portion on the inner side in the width direction with reference to the second groove portion extends downward more than a second outer half portion on the outer side in the width direction with reference to the second groove portion, in the open showcase according to any one of TECHNOLOGIES 1 to 4. As a result, it becomes easier to attach the trim member to the inner plate and the outer plate. Therefore, the open showcase can be easily manufactured.

[0063] (TECHNOLOGY 6) In the trim member, a plurality of the drain holes are formed, in the open showcase according to any one of TECHNOLOGIES 1 to 5. As a result, even when a large amount of condensed water is generated on the window plate, it can be appropriately drained easily.
