Description

  The present invention relates to a showcase that is installed on a counter of a restaurant or the like and stores stored items while displaying them.

  As a refrigerated showcase for storing refrigerated items such as foods and beverages, there is a so-called `` netacase '' that is installed at a counter in a sushi restaurant or the like and stores refrigerated foods such as stored sushi items while refrigerated. (See Patent Document 1). For example, as shown in FIG. 7, the refrigerated showcase 10 has a storage chamber 12 inside a heat insulating box 16 that is made of a heat insulating structure by filling heat insulating materials 32, 32 such as urethane foam between the exterior and the interior. A windshield 18 is fitted into a front opening 56 formed on the front side of the heat insulation box 16 so that the inside of the storage chamber 12 can be seen from the front. A cooling plate 30 is disposed on the lower surface of the upper heat insulating layer 26 formed above the storage chamber 12 in the heat insulating box 16. An upper evaporator 34 connected to a cooling device (not shown) is disposed inside the upper heat insulating layer 26 so as to come into contact with the cooling plate 30, and the cooling plate 30 is cooled by the refrigerant circulated and supplied to the upper evaporator 34. The storage chamber 12 is configured to be indirectly cooled.

Above the storage chamber 12, a fluorescent lamp 36 as an illumination device is attached via an illumination support 38 fixed to the cooling plate 30. The fluorescent lamp 36 is protected by a transparent resin cover 40 to prevent leakage due to water splashing during cleaning and deterioration due to rust. The direct contact is prevented so that the fluorescent lamp 36 is not damaged. The fluorescent lamp 36 is supported at a position spaced apart from the lower surface of the cooling plate 30 by a lighting support 38, and a heat exchange area of the cooling plate 30 is ensured.
JP-A-8-327209

  Thus, the conventional refrigerated showcase 10 employs the fluorescent lamp 36 as an illuminating device that illuminates the storage chamber 12, and the fluorescent lamp 36 is attached so as to protrude inward from the plate 30. Therefore, the volume of the storage chamber 12 is reduced by the amount of projection of the fluorescent lamp 36, and the space of the storage chamber 12 cannot be effectively used. Moreover, since the fluorescent lamp 36 generates heat when in use, the cooling efficiency in the storage chamber 12 is reduced, which increases the running cost.

  In view of the above problems, the inventor of the present application has conceived that an illumination device such as an LED element is accommodated in the space inside the windshield, and the invention “Showcase” according to Japanese Patent Application No. 2006-119692 (hereinafter referred to as a prior application). Filed a patent application. In the showcase 21 according to the prior application, as shown in FIG. 8, an LED lighting device 42 as a lighting device is installed in a space S of the windshield 18 via a required holder 44, thereby The conventional problems associated with use are preferably solved.

  Further, in the prior application, a protrusion 46 is formed on the front side of the holder 44, and a shielding member 50 that shields light is provided on the lower surface of the protrusion 46. That is, the light irradiated from the LED illumination device 42 and reflected by the glass inside the windshield 18 (inner glass 18a) (reflected light A) is shielded by the shielding member 50, and the reflected light A Is prevented from leaking outside. However, in the structure according to the prior application, the illuminance in the storage chamber 12 is slightly lowered due to the shielding effect of the shielding member 50. Moreover, depending on the shape of the windshield 18, the irradiation angle of the LED lighting device 42, etc., the light that has passed through the inner glass 18a may leak directly to the outside through the windshield 18 (arrow B in FIG. 8). reference). Then, the light leaked to the outside is reflected on the installation surface of the showcase 21, and the customer located in front of the showcase 21 may feel dazzling.

  That is, the present invention has been proposed to suitably solve the above-described problems, and provides a showcase that can suppress the leakage of light from the lighting device to the outside and does not darken the storage room. With the goal.

In order to overcome the above-mentioned problems and achieve the intended purpose, a showcase according to claim 1 comprises:

In addition, the same code | symbol is attached | subjected about the already-explained member demonstrated by the prior art. In the embodiment, a case will be described in which the showcase is a refrigerated showcase in which the temperature of the storage room is adjusted to a low temperature.

  As shown in FIG. 1, in the refrigerated showcase 100 according to the embodiment, the storage chamber 12 for storing refrigerated items such as fresh foods and beverages is internally defined in a heat insulating box 16 having a heat insulating structure. A front opening 56 is opened on the front side of the heat insulating box 16 facing the customer when the refrigerated showcase 100 is placed on a counter or the like, and a transparent windshield (transparent member) 18 is fitted into the opening 56. Thus, the articles stored in the storage chamber 12 can be viewed from the front outside. On the other hand, on the rear surface side of the heat insulating box 16, an article doorway 20 is opened, and a pair of sliding doors 22 and 22 held by rails 58 and 58 on the upper and lower sides are slidably arranged in the left-right direction. The article doorway 20 is configured to be openable and closable.

  A bottom plate 24 that defines the bottom surface of the storage chamber 12 is disposed on the upper surface of the lower heat insulation layer 43 formed below the storage chamber 12 in the heat insulation box 16. Further, the lower evaporator 45 in contact with the cooling device is arranged in a meandering manner so as to come into contact with the bottom plate 24, and the storage chamber 12 is indirectly cooled by cooling the bottom plate 24. ing. On the other hand, the upper heat insulating layer 26 formed on the top of the heat insulating box 16 is defined by the upper holder 28 supported by the top cover 16a of the heat insulating box 16 and the cooling plate 30 that forms the upper surface of the storage chamber 12. The formed space is configured by being filled with a heat insulating material 32. In addition, an upper evaporator 34 connected to the cooling device is meanderingly disposed on the upper heat insulating layer 26 so as to come into contact with the cooling plate 30.

  The cooling device that cools the storage chamber 12 is disposed in a machine room that is internally defined in a cabinet (not shown) that is integrally disposed adjacent to the heat insulation box 16, and includes a compressor, a condenser, a fan motor, and an expansion unit. It is composed of a valve or the like (both not shown). In the cooling device, the vaporized refrigerant compressed by the compressor is cooled by a fan motor in a condenser located downstream to be condensed and liquefied, and the liquefied refrigerant depressurized by the expansion valve is cooled at a low temperature by the upper evaporator 34 and the lower evaporator 45. Thus, the storage chamber 12 is cooled by being a vaporized refrigerant, and a cycle is returned to the compressor again.

  The windshield 18 is formed of a so-called pair glass in which an inner glass (transparent plate) 18a and an outer glass (another transparent plate) 18b are arranged to face each other with a predetermined distance therebetween. As shown in FIG. 1, the windshield 18 has a shape that gently slopes downward from the rear to the front, then curves downward, and slopes downward at a steep angle. For convenience of explanation, the curved portion of the windshield 18 may be referred to as a curved portion 66, and the upper side of the curved portion 66 may be referred to as a top portion 68 and the lower side may be referred to as a front portion 70. A required space S is defined between the inner glass 18a and the outer glass 18b by a plurality of spacers 110 (two upper and lower spacers 110, 110 are shown in FIG. 1). Each spacer 110 is provided over the entire circumference of the edge between the two glasses 18a and 18b, and ensures a separation interval between the two glasses 18a and 18b, and the atmosphere in the space S with respect to the storage chamber 12. It is designed to be sealed. The entire periphery of the edge of the windshield 18 is sealed by caulking with silicon or the like, and the space S between the two glasses 18a and 18b is kept in a sealed state.

  As shown in FIG. 2, an LED illumination device 120 including an LED element 124 is disposed through a required holder 122 inside the space S and on the upper edge of the top portion 68 of the windshield 18. ing. The holder 122 includes a main body part 132 having a channel-shaped cross section and an engaging part 134 that is integrally formed with the main body part 132 and engages with the spacer 110. The holder 122 is arranged in the space S in a state where the engaging portion 134 is engaged so as to embrace the spacer 110. The main body 132 has an opening 132a that opens toward the storage chamber 12, and a space in which the LED lighting device 120 can be stored is secured.

  The main body 132 facing the front of the refrigerated showcase 100 is formed of a non-transparent or translucent synthetic resin or the like so that the light from the LED lighting device 120 is not directly irradiated to the front and upper sides of the refrigerated showcase 100. It has become. Further, by making the main body 132 non-transparent or translucent, it is possible to prevent the substrate 126 (described later) of the LED lighting device 120 from being seen from the outside. The engaging portion 134 extends from an edge portion of the main body portion 132 in contact with the outer glass 18b positioned on the outer side toward the spacer 110 side positioned on the rear side. Configured to engage. That is, the engagement portion 134 is engaged with a rigid spacer 110 made of a metal such as aluminum, so that even when the holder 122 is elongated, warpage hardly occurs, and the holder 122 is moved along the spacer 110. It becomes possible to fix linearly. 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 18b, and the engaging portion 134 is bonded to the outer glass 18b with a double-sided tape 114 or the like. Is done. In other words, the vertical width l (see FIG. 3) of the holder 122 is set to coincide with the spacing between the inner glass 18a and the outer glass 18b. The spacer 110 is also fixed by adhering the inner surface of the inner glass 18 a (the surface facing the space S and the outer surface with respect to the storage chamber 12) with a double-sided tape 114.

  On the front side of the holder 122 facing the opposite side of the engaging portion 134, a shielding portion 62 configured to be elastic is provided. The shielding portion 62 is formed to extend from the front end portion 122a of the main body portion 132 to the front side with a required length on the space S side of the inner glass 18a. Further, as shown in FIG. 3, the shielding portion 62 is inclined at a predetermined angle from the lower end surface of the front end portion 122 a of the holder 122 toward the storage chamber 12 side. That is, the vertical width L from the front end of the shielding part 62 to the upper surface of the holder 122 is set to be larger than the separation interval between the two glasses 18a and 18b. Accordingly, when the holder 122 is disposed in the space S, the shielding portion 62 is elastically deformed along the inner glass 18a, and comes into close contact with the inner glass 18a pressed with a required elasticity. Yes. The shielding unit 62 is made of a material that can completely shield the light of the LED lighting device 120, for example, a soft material such as a synthetic resin. That is, the shielding unit 62 functions to prevent light leaking to the outside by shielding the light irradiated from the LED lighting device 120 and reflected by the inner glass 18a (hereinafter referred to as reflected light A). .

  On the space S side surface of the inner glass 18a, in the vicinity of the LED lighting device 120, a frosted glass-like portion 64 having an uneven surface treatment is formed. The frosted glass-like portion 64 scatters the light of the LED lighting device 120 while having light transparency, and allows light to pass at a predetermined ratio. Further, the frosted glass portion 64 is provided in a portion of the inner glass 18a facing a path of light that is irradiated from the LED lighting device 120 and leaks directly to the outside of the refrigerated showcase 100. That is, as shown in FIG. 1, among the light emitted from the LED lighting device 120, the light emitted at an acute angle forward passes through the inner glass 18a and directly goes from below the front portion 70 of the windshield 18 to the outside. There is a possibility of leakage (hereinafter, such light is referred to as direct leakage light B). Therefore, the frosted glass-like portion 64 is provided so as to cover a region on the space S side of the inner glass 18a and through which this direct leakage light B passes. 1 and 2, the light C traveling toward the storage chamber 12 without passing through the frosted glass portion 64 does not leak from the lower side of the windshield 18. In other words, as the range in which the frosted glass portion 64 is provided is increased, the amount of light directly radiated into the storage chamber 12 decreases, so that the frosted glass shape is on the path of the light C that does not leak to the outside. There is no need to provide the portion 64.

  In the embodiment, the rear edge portion (the right edge portion in FIG. 2) of the frosted glass portion 64 is located immediately below the LED lighting device 120. On the other hand, the front edge portion (left edge portion in FIG. 2) of the frosted glass-like portion 64 reaches the vicinity of the open end of the shielding portion 62. In other words, the front side of the frosted glass portion 64 is covered from the outside by the shielding portion 62. Thus, when the polished glass-like part 64 extends below the shielding part 62, when the reflected light A is shielded by the shielding part 62, a part of the reflected light A is caused by the polished glass-like part 64. The light is scattered and illuminated in the storage room 12 (see FIG. 4).

  The LED lighting device 120 used in the embodiment is configured by arranging a plurality of LED elements 124 of the same color in a straight line on a substrate 126 and connecting the plurality of substrates 126 in series. That is, as shown in FIG. 5, a board 126 extending in the width direction with a required length is formed by arranging a plurality of LED elements 124 in a row 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 12, the interior of the storage chamber 12 can be illuminated with a desired brightness. For example, assuming that the storage chamber 12 has a width dimension of 845 mm, a substrate 126 having a width dimension of 260 mm and 12 pieces of white LED elements 124 of 0.08 W provided as one unit, it is sufficient to connect three units. Brightness is secured. In the embodiment, the LED element 124 has only one color, but it is also possible to install a plurality of color LED elements.

(Operation of Example)
Next, the operation of the refrigerated showcase 100 according to the embodiment will be described. When the LED lighting device 120 is installed in the space S, first, the LED lighting device 120 is accommodated in the holder 122 and the lighting device 120 is fixed. Next, the engaging portion 134 is engaged with the spacer 110, and the holder 122 is disposed along the spacer 110. At this time, the shielding portion 62 is elastically deformed while being in contact with the inner glass 18a, and the lower surface of the shielding portion 62 is in close contact with the inner glass 18a. Further, a polished glass-like portion 64 formed in advance on the space S side surface of the inner glass 18 a is covered from above by the holder 122 and the shielding portion 62. The shielding part 62 is fixed to the inner glass 18a with an adhesive or the like applied to the lower surface. The upper surface of the engaging portion 134 and the surface of the outer glass 18 b on the space S side are attached by a double-sided tape 114, and the LED lighting device 120 is provided in the space S together with the holder 122. Then, the windshield 18 to which the LED lighting device 120 is attached is fitted into the front opening 56 of the heat insulating box 16.

  As shown in FIG. 4, when the LED lighting device 120 is operated, light is emitted from the lighting device 120 toward the storage chamber 12. Of this light, the light C that does not pass through the frosted glass portion 64 passes through the inner glass 18a and directly illuminates the storage chamber 12, and does not leak outside. Further, a part of the light C is reflected by the surface of the inner glass 18 a on the storage chamber 12 side and scattered as reflected light A by the polished glass portion 64. At this time, even if the reflected light A passes through the polished glass-like portion 64, the reflected light A is not leaked to the outside because it is shielded by the shielding portion 62.

  On the other hand, the direct leakage light B irradiated from the LED lighting device 120 arrives at the frosted glass portion 64 and a part thereof is scattered. The scattered direct leakage light B is shielded by the holder 122 and does not leak outside the refrigerated showcase 100. Further, a part of the directly leaked light B travels in the inner glass 18a, and a part of the inner glass 18a is further reflected by the surface of the inner glass 18a on the storage chamber 12 side, and is reflected as reflected light A to the polished glass-like portion 64. Head.

  On the other hand, the direct leakage light B after passing through the inner glass 18 a and entering the storage chamber 12 leaks to the outside through the front portion 70 of the windshield 18, but the direct leakage light B is transmitted through the polished glass portion 64. The energy is attenuated by the scattering of light and becomes weak light. Therefore, even if this directly leaked light B leaks to the outside, it does not feel dazzling. On the other hand, the reflected light A of the direct leakage light B reflected by the surface of the inner glass 18a on the storage chamber 12 side again arrives at the polished glass portion 64 and is scattered by the polished glass portion 64. Thereby, the illumination intensity of the storage chamber 12 is improved. Even if the reflected light A passes through the polished glass-like portion 64, it is shielded by the shielding portion 62 and does not leak out.

  As described above, in the refrigerated showcase 100 according to the embodiment, since the direct leakage light B is weakened when passing through the polished glass-like portion 64, even if the direct leakage light B leaks to the outside, it is refrigerated. The appearance of the showcase 100 is not impaired or the customer does not feel dazzling. Moreover, since the reflected light A reflected by the inner glass 18a is scattered by the frosted glass portion 64, the inside of the storage chamber 12 can be brightened. Moreover, even if a part of the reflected light A passes through the polished glass-like portion 64, it is completely shielded by the shielding portion 62, so that the reflected light A reflected by the inner glass 18a does not leak to the outside.

(Change example)
In addition, in the Example, the case where the frosted glass-like part 64 was formed by surface-treating the inner glass 18a in uneven | corrugated shape was illustrated. However, for example, the frosted glass portion may be formed by coating the surface of the inner glass 18a to form an uneven coating film. In the embodiment, the frosted glass portion 64 is provided on the surface of the inner glass 18a on the space S side. However, as shown in FIG. 6, the frosted glass portion 65 is provided on the surface of the inner glass 18a on the storage chamber 12 side. It may be provided. Thus, when the frosted glass-like part 65 is provided in the storage chamber 12 side of the inner glass 18a, it becomes possible to make the area small compared with an Example. That is, as shown in FIG. 6, since the direct leakage light B travels obliquely forward in the inner glass 18a, the position where the direct leakage light B passes through the surface of the inner glass 18a on the storage chamber 12 side (in FIG. 6). see P ₁₎ is a front side of the position which passes through the surface of the space S side (see FIG P _2). Accordingly, the rear edge of the frosted glass portion 65 can be set on the front side as compared with the embodiment, and as a result, the area of the frosted glass portion 65 can be reduced. As a result, the processing cost of the frosted glass-like portion 65 can be reduced, and the amount of light directly irradiated onto the storage chamber 12 without passing through the frosted-glass-like portion 65 increases, so that the inside of the storage chamber 12 becomes brighter.

  In the embodiment, the case where the LED illumination device 120 using the LED element 124 is adopted as the illumination device is shown, but an illumination device using other light emitting elements can also be adopted. Furthermore, although the pair glass which consists of a pair of glass 18a, 18b was employ | adopted as a transparent member in the Example, you may comprise a transparent member from single glass. In this case, the lighting device is attached to the outside of the single glass (outside of the storage chamber 12). It is also possible to configure the transparent plate from a transparent plastic or the like.

  Further, in the embodiment, the refrigerated showcase 100 for cooling the inside of the storage chamber 12 has been described, but the show in which the storage chamber 12 is heated to a predetermined temperature with a heater or the like and the article is stored in a heated state. Various showcases having other configurations such as a case may be used.
