(See Patent Document 1). For example, as shown in FIGS. 20 and 21, the refrigerated showcase 10 includes a storage chamber 12 that stores articles in a refrigerator, and a cooling device such as a compressor and a condenser for cooling the storage chamber 12 (both not shown). Is provided adjacent to the machine room 14. The storage chamber 12 is defined in the inside of a heat insulation box 16 having a heat insulation structure filled with a heat insulating material 32 such as urethane foam between the exterior and the interior, and is formed on the front side of the heat insulation box 16. A windshield 18 is fitted into the opening 56 so that the interior of the storage chamber 12 can be seen from the front.

  As shown in FIG. 21, an article entrance / exit 20 for the storage chamber 12 is opened on the rear surface side of the heat insulation box 16, and a slide door 22 is slidably attached to the article entrance / exit 20. By sliding in the left-right direction and opening the article entrance 20, the article is allowed to be taken in and out of the storage chamber 12.

The cover member 86 is formed of a transparent resin so as to transmit light emitted from the LED elements 68a, 68b, and 68c. The outer shape of the cover member 86 is substantially the same as the inner shape of the opening 64 of the cooling plate 62. I'm doing it. Further, a protrusion 86 a is formed on the back surface (upper surface) of the cover member 86, and is fitted into a groove 84 a formed in the packing 84. Further, as shown in FIG. 2, a pair of locking portions 86 b and 86 b are provided on the back surface of the cover member 86, and are engaged with stepped portions 78 e and 78 e formed inside the holder 78. A cover member 86 is attached to the opening 64. That is, the inside of the holder 78 to which the LED lighting device 70 is attached is sealed with respect to the storage chamber 52 by the packing 84 and the cover member 86 to prevent water from entering from the outside and the holder 78 by the desiccant 80. The internal atmosphere is kept at a low humidity.

  As shown in FIG. 5, an operation panel 88 for performing various operations of the refrigerated showcase 50 is disposed on the rear surface portion 14 a of the machine room 14, and “red”, “blue”, “green” provided on the panel 88. By operating each of the operation buttons 76a, 76b, and 76c, the ON / OFF operation of the LED elements 68a, 68b, and 68c corresponding to the color can be switched. In other words, the LED illumination device 70 is configured to change the illumination color according to the article displayed in the storage chamber 52. Of course, it is possible to simultaneously emit all the colors of “red”, “blue”, and “green”. Reference numeral 90 denotes a power switch of the LED lighting device 70.

  As shown in FIG. 1, the space S of the windshield 18 is provided with a reflector 118 that reflects light from the LED lighting device 70 and brightens the interior of the storage chamber 52. The reflecting plate 118 is made of, for example, stainless steel in a thin plate shape, and is adhered to the space S side surface of the glass 18a on the storage chamber 52 side with a double-sided tape or the like. In addition, the installation place of this reflecting plate 118 should just be a position which can reflect the light from LED lighting apparatus 70 in the windshield 18. FIG. However, instead of the reflecting plate 118, a reflecting film may be attached to the inner glass 18a. Alternatively, a reflective surface may be formed by printing a pigment such as silver on the inner glass 18a.

(Operation of Example 1)
Next, the operation of the refrigerated showcase 50 according to the first embodiment will be described. When the LED lighting device 70 is operated, the power switch 90 disposed on the rear surface portion 14a of the machine room 14 is turned on. For example, when it is desired to turn on all the colors of the LED lighting device 70, all the LED elements 68a, 68b, 68c on the substrate 72 are turned on by pressing all the operation buttons 76a, 76b, 76c. At this time, since the cover member 86 is formed of a transparent resin, the light from the LED lighting device 70 can illuminate the storage chamber 52 without being weakened.

  Since the reflecting plate 118 is affixed to the glass 18a inside the front glass 18, the light from the LED lighting device 70 does not directly enter the eyes of the customer. Further, the light from the LED lighting device 70 is reflected by the reflecting plate 118, and the inside of the storage chamber 52 becomes brighter. Further, the space S of the windshield 18 is sealed by the spacer 18b, and dust or dirt does not adhere to the reflecting plate 118 in the space S. Therefore, it is not necessary to clean the reflecting plate 118. Further, since it is not necessary to clean the reflector 118, it is not necessary to ensure the rigidity of the reflector 118, so that resource and cost savings can be realized, and there is a selection range of materials that can be adopted for the reflector 118. Enlarged. Furthermore, since the reflection plate 118 is provided in the space S and is not exposed to the storage chamber 52, the volume of the storage chamber 52 is not reduced, and the cleaning of the storage chamber 52 is facilitated.

  Further, when it is desired to change the illumination color according to the foods to be displayed, it is only necessary to press only the operation buttons 76a, 76b, and 76c corresponding to the LED elements 68a, 68b, and 68c to be lit on the operation panel 88. . That is, for example, when only the “red” LED element 68a is to be turned on, only the operation button 76a corresponding to the element 68a is pressed, and the other operation buttons 76b and 76c are turned off. As described above, the refrigerated showcase 50 according to the first embodiment can easily change the illumination color according to the food to be displayed.

  Further, since the LED lighting device 70 is disposed in the upper heat insulating layer 54 outside the storage chamber 52, the space in the storage chamber 52 can be used effectively, and large foodstuffs can be displayed and stored. Can do. Further, since the LED lighting device 70 does not protrude into the storage chamber 52 unlike the conventional fluorescent lamp 36, the inside of the storage chamber 52 can be easily cleaned. Moreover, since the inside of the holder 78 to which the LED lighting device 70 is attached is sealed, water does not enter from the outside, and the LED lighting device 70 does not break down or leak. Furthermore, since the desiccant 80 is accommodated in the accommodating portion 78c of the holder 78, the atmosphere inside the holder 78 can be kept low.

  Since the LED elements 68a, 68b, and 68c do not generate heat unlike the fluorescent lamp 36 conventionally used, the capacity of the cooling device can be reduced and the running cost can be suppressed. In addition, the lifetime of the LED elements 68a, 68b, and 68c is much longer than that of a fluorescent lamp or the like, and there is almost no deterioration over time, so that the emission color is not faint and the illuminance is less likely to decrease. Therefore, it is not necessary to perform complicated replacement work that is necessary for the conventional fluorescent lamp 36. Note that the lead wire 74 of the LED lighting device 70 is disposed in the upper heat insulating layer 54 and is led out to the machine chamber 14 and is not exposed to the storage chamber 52. It will never be.

When the LED lighting device 70 is operated, the power switch 90 disposed on the rear surface portion 14a of the machine room 14 is turned on. For example, when it is desired to light all the colors of the LED lighting device 70, all the LED elements 68a, 68b, 68c on the substrate 72 can be lighted by pressing all the operation buttons 76a, 76b, 76c. . At this time, since the windshield 108 is transparent, the light from the LED lighting device 70 can illuminate the storage chamber 52 without being weakened. In addition, when it is desired to change the illumination color in accordance with the foods to be displayed, the operation buttons 76a corresponding to the LED elements 68a, 68b, 68c to be lit on the operation panel 88 as described in the first embodiment. , 76b, and 76c.

  That is, according to the refrigerated showcase 100 according to the second embodiment, since the LED lighting device 70 is disposed in the space S of the windshield 108, the space of the storage chamber 52 can be used effectively, which is large. Ingredients can be displayed and stored. Further, unlike the conventional fluorescent lamp 36, the LED lighting device 70 does not protrude into the storage chamber 52, so that the interior of the storage chamber 52 can be easily cleaned. Furthermore, since the space S of the windshield 108 to which the LED lighting device 70 is attached is sealed, water does not enter from the outside and the LED lighting device 70 does not break down or leak. Furthermore, since the desiccant 80 is stored in the case member 112 provided below the windshield 108, the atmosphere inside the space S can be kept low.

  Further, by adopting the LED elements 68a, 68b, 68c as the illuminating device instead of the conventional fluorescent lamp 36, the same effects as those of the first embodiment can be obtained, such as reduction in running cost. In addition, since the lead wire 74 of the LED lighting device 70 is directly led out from the space S of the windshield 108 to the machine chamber 14, the lead wire 74 is not exposed to the storage chamber 52 and becomes an obstacle.

  In Example 2, the film or printing that covers the LED lighting device 70 is not limited to black, and may be any color that matches the stored article. Further, the spacer 110 that separates the two glasses 108a and 108b of the windshield 108 from each other by a necessary distance is not limited to the configuration shown in the second embodiment, and a conventionally known configuration can be appropriately employed.

  Further, the LED lighting device 70 shown in the first and second embodiments is configured by the LED elements 68a, 68b, and 68c composed of “red”, “blue”, and “green”, but adopts LED elements of other colors. May be. Furthermore, the types of colors are not limited to three, and one, two, or four or more colors may be emitted.

  Next, a refrigerated showcase according to Example 3 will be described. In the third embodiment, only the differences from the first and second embodiments will be described, and the same members are denoted by the same reference numerals and the description thereof is omitted.

  In Example 2 described above, the LED lighting device 70 is directly fixed in the space S of the windshield 108 by the double-sided tape 114. However, in the refrigerated showcase 140 according to the third embodiment, as shown in FIG. 10, the LED lighting device 120 is disposed in the space S of the Freon glass 108 via the required holder 122.

  As shown in FIG. 10, the holder 122 that accommodates and holds the LED lighting device 120 is formed integrally with the main body portion 132 having a channel section (a part facing the front and the upper side) 132 having a cross-sectional channel shape. The engaging portion 134 is engaged with the spacer 110. And the holder 122 is arrange | positioned in the space S of the windshield 108 in the state which engaged the part 110b extended in the width direction above the storage chamber 52 in the said spacer 110 so that the engaging part 134 may embrace. Is done.

  The main body 132 is formed with an open portion 132a that opens downward, that is, toward the storage chamber 52, in the longitudinal direction, and a storage space 136 that can store the LED lighting device 120 is defined therein. Yes. In addition, a holding portion 138 that holds the LED lighting device 120 in a state where the LED lighting device 120 is inclined at a required angle is formed in the accommodation space 136. That is, as shown in FIG. 10, the LED illumination device 120 is held in an inclined state by the holding portion 138 so that the irradiation direction of the LED element is oriented in a direction that can favorably illuminate the interior of the storage chamber 52. Is done. Further, when the LED lighting device 120 is attached to the holder 122, the substrate 126 can be positioned (temporarily fixed) by the holding portion 138. In the third embodiment, as shown in FIG. 10, protruding (rib-shaped) portions are formed in the accommodation space 136 and these are used as the holding portions 138. However, the holding portions 138 are not limited to this configuration. However, other configurations may be employed as long as the LED lighting device 120 can be held in an inclined posture.

  The main body 132 facing the outside of the refrigerated showcase 140 is made of a non-transparent or translucent synthetic resin or the like, and the light from the LED lighting device 120 is directly irradiated to the front and upper sides of the refrigerated showcase 140. Not to be. Furthermore, by making the main body 132 non-transparent or translucent, it is possible to prevent the substrate 126 of the LED lighting device 120 from being seen from the outside. The open part 132a of the main body part 132 may be closed with a transparent lid member.

  The engaging portion 134 extends toward the spacer 110 at the edge 132b of the portion of the main body 132 that contacts the outer glass 108a. The engaging portion 134 holds the portion 110b of the spacer 110. Configured to engage. In other words, the engagement portion 134 is engaged with the case member 112 of the spacer 110 made of metal such as aluminum and has rigidity, so that even when the holder 122 is elongated, the warp hardly occurs, and the holder 122 is made to be a spacer. 110 can be fixed linearly along the portion 110b. The upper surface of the engaging portion 134 is in contact with the inner surface (the surface on the space S side) of the outer glass 108a, and the engaging portion 134 is bonded to the outer glass 108a with a double-sided tape 114 or the like. Is done. Note that the fixing with the double-sided tape 114 or the like to the holder 122 is only the fixing of the engaging portion 134 and the outer glass 108a. The portion 110b of the spacer 110 is fixed by bonding the surface of the portion 110b on the storage chamber 52 side and the inner surface of the inner glass 108b (surface on the space S side) with a double-sided tape 114.

  The LED lighting device 120 used in the third embodiment is configured by arranging a plurality of LED elements 124 of the same color in a straight line in a row on a substrate 126 and connecting the plurality of substrates 126 in series. That is, as shown in FIG. 11, a plurality of LED elements 124 arranged in a row on a substrate 126 extending in the width direction with a required length is regarded as one unit, and a plurality of these units are connected in series to form an LED. The illuminating device 120 is comprised. The units are connected by connecting connectors 128 and 128 provided at both ends of each board 126 via a relay line 130. Therefore, by changing the number of units connected according to the width dimension of the storage chamber 52, the interior of the storage chamber 52 can be illuminated with a desired brightness. For example, if the storage chamber 52 has a width dimension of 845 mm, and a substrate 126 having a width dimension of 260 mm and 12 pieces of white LED elements 124 of 0.08 W are provided as one unit, it is sufficient to connect three units. Brightness is secured. In the third embodiment, since only one LED element 124 is used, the operation buttons 76a, 76b and 76c corresponding to the respective colors shown in the first and second embodiments are not necessary, and the power switch 90 is turned on. Only the LED lighting device 120 is activated (lighted).

(Operation of Example 3)
Next, the operation of the third embodiment will be described below. When the LED illumination device 120 is disposed in the space S, first, the LED illumination device 120 is accommodated in the accommodation space 136 in the holder 122. That is, the substrate 126 is fixed to the holding portion 138, and the LED lighting device 120 is held in the accommodation space 136 in a state where the LED lighting device 120 is inclined at a required angle. At this time, since the LED lighting device 120 is positioned (temporarily fixed) by the holding portion 138, the assembly work of the LED lighting device 120 can be performed efficiently.

  Next, the engaging portion 134 is engaged with the upper portion 110b extending in the width direction of the spacer 110, and the holder 122 is disposed along the portion 110b. That is, the case member 112 of the spacer 110 is linearly fixed to the windshield 108 with a required rigidity, and the holder 122 is warped by engaging the engaging portion 134 so as to hold the case member 112. It becomes difficult to generate and can be placed straight. Therefore, a process for correcting the warp of the holder 122 is not necessary, and the attaching operation of the holder 122 becomes efficient. Then, the LED lighting device 120 is provided in the space S together with the holder 122 by sticking the upper surface of the engaging portion 134 and the space S side surface of the outer glass 108 a with the double-sided tape 114.

  Next, when the LED lighting device 120 is operated, the power switch 90 disposed on the rear surface portion 14a of the machine room 14 is turned on. At this time, the portion (opening portion 132a) of the main body 132 in the holder 122 on the side of the storage chamber 52 is open, and the windshield 108 is transparent, so that the light from the LED lighting device 120 is not weakened. Can illuminate. In addition, as described above, the LED illumination device 120 is accommodated in the holder 122 in a state where the LED illumination device 120 is inclined at a required angle. Further, since the main body 132 of the holder 122 is formed of a non-transparent or translucent material, the light of the LED element 124 is not directly irradiated to the front or upper side, The sushi craftsmen etc. located on the upper side do not feel dazzling. Further, the substrate 126 and the like of the LED lighting device 120 are not visible from the outside, and the aesthetic appearance of the refrigerated showcase 140 is not impaired.

  As described above, the refrigerated showcase 140 according to the third embodiment is configured such that the holder 122 is disposed in the space S in a state where the engaging portion 134 is engaged with the spacer 110. However, the holder 122 may be configured by only the main body portion 132 and may be fixed in the space S without being engaged with the spacer 110. Further, the LED lighting device 120 does not necessarily need to be housed in the holder 122 in an inclined state as long as the light suitably reaches the housing chamber 52, and may be provided in a parallel posture with respect to the windshield 108. Further, the desiccant 80 shown in the first embodiment may be accommodated in the holder 122. Furthermore, the spacer 110 in the third embodiment is arranged over the entire periphery between the two glasses 108a and 108b and is configured to seal the space S as in the second embodiment. However, if it is not necessary to seal the space S and dehumidify with the desiccant 80, the spacer 110 does not necessarily have to be provided over the entire periphery between the two glasses 108a and 108b.

(Modification 1 of Example 3)
In the refrigerated showcase 140 according to the third embodiment described above, when the LED lighting device 120 is operated, the light emitted from the LED lighting device 120 may vary depending on the inclination angle of the substrate 126, the shape of the inner glass 108b, and the like. There is a case where it is reflected by the glass 108b and leaks to the outside. That is, as shown in FIG. 16, the light of the LED illumination device 120 is repeatedly reflected in the inner glass 108b, so that a plurality of reflected light passes through the outer glass 108a and leaks to the outside. In this case, when the refrigerated showcase 140 is viewed from the front side, a plurality of light spots (light spots P ₁ , P ₂ , P ₃ ...) Are regularly arranged near the holder 122 in the outer glass 108a. There is a problem that it appears in a state and the appearance of the refrigerated showcase 140 deteriorates. As shown in FIG. 16, among the reflected light leaking to the outside, the first reflected light L ₁ passing through the nearest vicinity of the front end portion 122a on the side away from the spacer 110 in the holder 122 has the least number of reflections. Strong reflected light. Therefore, the light spot P ₁ formed by the first reflected light L ₁ is as conspicuous brightest. That is, the intensity of the reflected light leaking out of the windshield 108 decreases as it moves away from the front end 122a of the holder 122 (away from the outer peripheral edge of the windshield 108).

Therefore, in the refrigerated showcase 140 according to the first modification of the third embodiment, as shown in FIG. 17, a thin plate-shaped shielding member 198 is provided on the outer surface of the outer glass 108a, and the LED lighting device 120 leaks outside. of the light, and is configured so as to shield at least the first reflected light L _1. The shielding member 198 is made of a metal or resin made of a material having low light transmittance in a rectangular thin plate shape that is long in the width direction, and is adhered to the entire width direction of the outer surface of the outer glass 108a with an adhesive. It is done. Further, the length dimension l in the short direction of the shielding member 198 is set to a value capable of shielding the first reflected light L ₁ . That is, when the shielding member 198 is attached to the outer glass 108a, the front edge portion 198a of the shielding member 198 extends to the front side (left side in FIG. 17) by a required length from the front end portion 122a of the holder 122. The holder 122 can be completely covered.

As described above, according to the refrigerated showcase 140 according to the modified example 1, the strongest first reflected light L ₁ among the reflected lights of the LED lighting device 120 is shielded by the shielding member 198. Can improve. When the shielding member 198 shields only the first reflected light L ₁ , the area of the shielding member 198 can be set to the minimum necessary. Therefore, the area of the windshield 108 covered with the shielding member 198 is also minimized, and the amount of light taken from the outside into the cabinet is hardly reduced. Note that the reflected light other than the first reflected light L ₁ (second reflected light L ₂ , third reflected light L ₃ ...) Leaks outside without being shielded by the shielding member 198. Since the reflected light is repeatedly reflected more than the first reflected light L ₁ , the light spots P ₂ , P ₃ ... Are not so noticeable when the refrigerated showcase 140 is viewed from the front side. However, if necessary, the length dimension l of the shielding member 198 may be increased so that the second reflected light L ₂ or the third reflected light L ₃ can be shielded. In the first modification, the shielding member 198 is formed of a thin plate, but the shielding member 198 may be formed of an adhesive sheet having low light transmittance.

(Modification 2 of Example 3)
Next, a refrigerated showcase 140 according to Modification 2 of Embodiment 3 will be described. As described above, in the first modification, the shielding member 198 is provided on the outer surface of the outer glass 108a. On the other hand, as shown in FIG. 18, the shielding member 200 in the second modification is provided at a portion facing the opposite side of the engaging portion 134 of the holder 122 on the space S side of the inner glass 108b. That is, in the second modification, the shielding member 200 is provided on the space S side of the inner glass 108b so as to be close to the front end portion 122a on the opposite side of the spacer 110 in the main body portion 132. This shielding member 200 is installed to shield the first reflected light L _{1 in} the same manner as the shielding member 198 of the first modification, and a metal or a synthetic resin having a low light transmittance is formed into a thin plate shape. Formed. However, since the shielding member 200 of Modification 2 is provided on the space S side of the inner glass 108b, the length dimension l ′ in the short direction can be reduced.

That is, according to the refrigerated display case 140 according to Modification 2, which is provided in the space S side of the inner glass 108b may shield member 200, in the widthwise direction required to block the first reflected light L ₁ length The dimension l ′ can be set smaller than the length dimension l of the first modification. Therefore, the area of the shielding member 200 becomes smaller, and external light can easily enter the interior, so that the interior can be kept brighter. Further, since the area of the shielding member 200 is reduced, the manufacturing cost of the shielding member 200 is also reduced. It should be noted that the shielding member 200 of the second modification may also be modified so as to shield the second and third reflected lights L ₂ , L _{3 and the} like instead of shielding only the first reflected light L ₁ .

In addition, the structure of the shielding members 198 and 200 shown in the modified examples 1 and 2 is an example, and other configurations can be used as long as the reflected light of the LED lighting device 120 can be prevented from leaking to the outside. The configuration can be appropriately adopted. Accordingly, the installation location of the shielding member may be provided anywhere on the windshield 108, such as the inner surface of the outer glass 108a, as long as the reflected light can be suitably shielded. That is, since the light reflection direction (appearance position of the light spots P ₁ , P ₂ , P ₃ ...) Varies depending on the embodiment of the refrigerated showcase 140, the light is shielded so that at least the first reflected light L ₁ can be shielded. A member may be provided at an appropriate location on the windshield 108. Further, as a shielding member, a coating material having low light transmittance may be sprayed on appropriate portions of the outer glass 108a or the inner glass 108b. Further, as shown in FIG. 19, a shielding member 202 may be integrally formed at the lower end of the front end portion 122 a of the holder 122.

Further, a cool air circulation type in which the cool air cooled by the evaporator 34 is circulated to the storage chamber 52 to cool the storage chamber 52, or a cool air circulation passage is provided outside the storage chamber 52, and the cool air is circulated through the passage. Thus, other refrigerated showcases such as a type in which the storage chamber 52 is cooled in a high humidity state may be used.

  Next, the refrigerated showcase according to Example 6 will be described below. Also in the sixth embodiment, only the changes from the first to fifth embodiments will be described.

  14 and 15 are diagrams showing a refrigerated showcase 180 according to the sixth embodiment. As illustrated in FIG. 14, the refrigerated showcase 180 according to the sixth embodiment is not a type in which the evaporator 34 is disposed in the upper heat insulating layer 54 as illustrated in the first to fifth embodiments, but a large evaporator 182. Is exposed in the upper part of the storage chamber 192. The LED lighting device 120 is housed in a holder 184 disposed in an empty space V between the upper portion of the housing chamber 192 and the evaporator 182 in the windshield 108.

  That is, as shown in FIG. 14, the evaporator 182 is fixed via a mounting portion 186 that extends downward from the vicinity of the upper edge portion 108c of the windshield 108 to a predetermined length, and the evaporator 182 and its evaporator 182 A required empty space V is formed between the windshield 108 positioned above. The holder 184 is provided in a portion of the inner glass 108b of the windshield 108 close to the mounting portion 186, and the LED lighting device 120 is accommodated in the holder 184.
