MODE FOR CARRYING OUT THE INVENTION

[0010] (Embodiment 1) Hereinafter, Embodiment 1 of the present disclosure will be described with reference to the accompanying drawings. The following Embodiment 1 is an example embodying the present disclosure and is not intended to limit the technical scope of the present disclosure.

[0011] In addition, in the cross-sectional views of the accompanying drawings, basically, the hatching of the broken cross-section is omitted.

[0012] [1] Configuration of Temperature Management Device First, the overall configuration of the temperature management device 1 according to the present embodiment will be described with reference to FIGS. 1 to 3.

[0013] In this embodiment, for convenience of explanation, the vertical direction in the state where the temperature management device 1 can be used is defined as the up-down direction D1. Also, based on the direction when the temperature management device 1 is viewed from the front, the left-right direction D2 is defined, and the front-back direction D3 is defined with the front side of the temperature management device 1 being the front and the back side being the rear. However, the definition of these directions is not intended to limit the usage direction (the direction during use) of the temperature management device 1.

[0014] The temperature management device 1 is a device provided with a storage body 2 capable of accommodating articles to be temperature-managed inside. In this embodiment, the temperature management device 1 is, for example, a furniture with a door that can be installed in a commercial facility such as a convenience store or a supermarket and can display products (that is, articles to be temperature-managed) maintained in a refrigerated or frozen state. In other words, the temperature management device 1 is a reach-in showcase such as a reach-in refrigerator or a reach-in freezer.

[0015] As shown in FIGS. 1 and 2, the temperature management device 1 includes a storage body 2 in which products are displayed inside, and a temperature management device member 3 used for the temperature management device 1. In this embodiment, the temperature management device member 3 is a door-shaped member. The region surrounded by the dashed line in FIG. 1 represents a schematic cross-sectional view of the temperature management device 1 viewed from above.

[0016] The storage body 2 houses a cooling device (not shown) including a compressor for cooling the interior of the storage, a control device for controlling the cooling device, and a power supply unit (not shown) for supplying power to the cooling device, the control device, and a lighting device 5 described later, etc. In this embodiment, the power supply unit has a power supply circuit that converts AC power from an external power supply such as a commercial power supply into DC power and supplies the converted DC power to the lighting device 5. In the power supply unit, the circuit for supplying power to the cooling device and the control device and the above power supply circuit for supplying power to the lighting device 5 may be separately divided.

[0017] Furthermore, as shown in Figure 2, the storage unit 2 has multiple shelves 21 for displaying goods inside. In other words, the storage unit 2 has multiple shelves 21 on which objects (in this case, goods) are placed. Each shelf 21 is arranged inside the storage unit 2 with spacing along the vertical direction D1. Inside the storage unit 2, objects are placed on each shelf 21 and on the bottom of the storage unit 2.

[0018] The front of the storage unit 2 is provided with a rectangular opening 20 that is open to the outside. In Figure 1, the opening 20 is shown with a dashed line because it is closed by a door 4, which will be described later. Through this opening 20, it is possible to bring objects into the storage unit 2 from the outside, or to take out objects displayed inside the storage unit 2 from the outside. In this embodiment, as shown in Figure 1, the opening 20 is divided into three openings 20a, 20b, and 20c by four support columns 22 that are spaced apart along the left-right direction D2. Each support column 22 is a rectangular prism with a length in the vertical direction D1, extending from the upper end to the lower end of the opening 20. The opening 20 does not have to be divided, for example, it may be divided into two, or it may be divided into four or more.

[0019] As shown in Figure 3, the temperature control device component 3 comprises a door body 4 and one or more (in this case, two) lighting devices 5. The area enclosed by the dashed line in Figure 3 represents a schematic cross-sectional view of the temperature control device component 3 as seen from above. In this embodiment, as shown in Figure 1, the temperature control device 1 comprises three temperature control device components 3a, 3b, and 3c corresponding to three openings 20a, 20b, and 20c, respectively. In the following, unless otherwise distinguished, the three openings 20a, 20b, and 20c will be referred to as "opening 20". Also, in the following, unless otherwise distinguished, the three temperature control device components 3a, 3b, and 3c will be referred to as "temperature control device component 3".

[0020] As shown in Figure 3, the door body 4 is capable of opening and closing the opening 20 of the storage body 2 and has a window portion 41 and a frame body 42. The window portion 41 is made of a transparent material such as glass. When the door body 4 is closed, the inside of the storage body 2 can be seen through the window portion 41. In this embodiment, the window portion 41 has a plurality (here, two) of transparent plates 411 arranged in the thickness direction (front-to-back direction D3). In other words, the window portion 41 is a multi-layer structure having a plurality of transparent plates 411. The frame body 42 supports the window portion 41. Specifically, the frame body 42 supports each transparent plate 411 by surrounding its upper end, lower end, right end, and left end. Therefore, the space between each transparent plate 411 is sealed by the frame body 42. This space is filled with air, for example, but may also be a vacuum.

[0021] In this embodiment, the window portion 41 does not have a rail (not shown) connecting the upper and lower ends of the frame 42, nor a rail connecting the left and right ends of the frame 42, but it may have such rails. In this case, the window portion 41 only needs to be transparent in parts other than the rails. Of course, if the rails are made of a transparent material, the entire window portion 41, including the rails, may be transparent.

[0022] The door body 4 is rotatably attached to the storage body 2 so as to open and close the corresponding opening 20 by a pair of shaft portions 421 that are positioned to protrude from the upper and lower ends of one end (in this case, the right end) in the left-right direction D2 of the frame body 42. As a result, the door body 4 is rotatable between an open position that opens the inside of the storage body 2 to the outside and a closed position that closes the inside of the storage body 2 to the outside. In the closed position, the frame body 42 of the door body 4 closes the corresponding opening 20 by making close contact with the front surface of the other of the two corresponding support columns 22.

[0023] Furthermore, the frame 42 is fitted with a handle 43 for gripping when opening and closing the door 4. The handle 43 is located at the end of the frame 42 opposite to the rotation axis side of the door 4 (in this case, the left end) in the left-right direction D2. More specifically, the handle 43 is located in the center of the left end of the frame 42 in the vertical direction D1. This allows a person to move the door 4 between the closed and open positions by gripping the handle 43 and pushing or pulling the door 4.

[0024] Each lighting device 5 is positioned on the door 4 and illuminates the interior of the storage body 2 at least when the door 4 is in the closed position. In other words, each lighting device 5 only needs to have its illumination direction directed towards the interior of the storage body 2 at least when the door 4 is in the closed position, and for example, its illumination direction may be directed towards the exterior of the storage body 2 when the door 4 is in the open position. As shown in Figures 4 and 5, each lighting device 5 is a unit having a length in the vertical direction D1 and comprises a circuit board 51, a power supply unit 52, a case 53, and a pair of side covers 54. The area enclosed by the dashed line in Figure 5 represents a schematic perspective view of the lighting device 5 from a different angle, with some parts enlarged.

[0025] The substrate 51 is formed from, for example, ceramics, resin material, or an insulating coated metal material, and has a length in the vertical direction D1. Multiple light sources 55 are mounted on one surface of the substrate 51 so as to be aligned along the vertical direction D1. The surface on the substrate 51 on which each light source 55 is mounted becomes the illumination surface from which light is emitted from each light source 55. The substrate 51 is also provided with a pair of electrodes (not shown) for supplying power to each light source from the power supply unit of the storage unit 2.

[0026] Each light source 55 is, for example, a surface-mount type LED (Light Emitting Diode) element. Note that each light source 55 is not limited to LED elements; it may also be other light-emitting elements such as semiconductor lasers, organic EL elements, or inorganic EL (Electro-Luminescence) elements. In this embodiment, each light source 55 is connected in series, but it may also be connected in parallel, or a combination of series and parallel connections.

[0027] The power supply unit 52 is located at one end (in this case, the upper end) of the substrate 51 in the vertical direction D1, and is used to supply power to each light source 55 from the power supply unit of the storage unit 2. In this embodiment, the power supply unit 52 has a pair of power supply lines 521 that are connected to a pair of electrodes provided on the substrate 51. One end of each power supply line 521 is electrically connected to the corresponding electrode of the pair of electrodes. Specifically, one end of one of the pair of power supply lines 521 is electrically connected to the anode of the pair of electrodes, and one end of the other power supply line is electrically connected to the cathode of the pair of electrodes. In addition, a connector 522 for electrically connecting to the power supply unit is attached to the other end of each power supply line 521.

[0028] The case 53 is formed from a resin material such as acrylic resin or polycarbonate resin, or a transparent material such as glass, and is a hollow cylindrical body having a fan-shaped cross-section in a plan view when viewed from above, and a length in the vertical direction D1. The upper and lower ends of the case 53 are open, and the substrate 51 can be housed in the case 53 by inserting the substrate 51 from either the upper or lower end.

[0029] More specifically, as shown in Figure 6, case 53 comprises, in a plan view from above, an arc-shaped curved plate 531 and a first flat plate 532 extending from one end of the curved plate 531 to a virtual center point P1 of the arc. Case 53 also comprises a second flat plate 533 extending from the other end of the curved plate 531 to the virtual center point P1 of the arc, and a third flat plate 534 connecting the first flat plate 532 and the second flat plate 533. The third flat plate 534 is positioned at a predetermined distance from the virtual center point P1, and the substrate 51 is placed on the third flat plate 534. Specifically, a pair of hook-shaped support plates 535 having a length in the vertical direction D1 are integrally formed on the third flat plate 534 at a distance from the substrate 51 in the width direction. Then, by inserting the substrate 51 between each support plate 535 and sliding the substrate 51 upward (or downward), it is possible to fix the substrate 51 with each support plate 535 and place it on the third flat plate 534. When the substrate 51 is placed on the third flat plate 534, the side of the substrate 51 opposite to the mounting surface on which each light source 55 is mounted comes into contact with the inner surface of the third flat plate 534.

[0030] As described above, in this embodiment, each of the one or more lighting devices 5 has a substrate 51 on which a light source 55 is mounted, and a case 53 that houses the substrate 51. The substrate 51 has the light source 55 mounted on one surface in the thickness direction, and the other surface in the thickness direction, the back surface, is in contact with the case 53 (in this case, the third flat plate 534) and is housed in the case 53. This increases the contact area between the substrate 51 and the case 53, making it easier to efficiently dissipate the heat generated by the substrate 51 through the case 53.

[0031] Each side cover 54 is formed from the same material as the case 53 and is a flat plate-shaped member having a fan-shaped cross-section when viewed from above in a plan view. The upper side cover 54 of the pair of side covers 54 fits into the opening at the upper end of the case 53 to close the opening, and the lower side cover 54 fits into the opening at the lower end of the case 53 to close the opening.

[0032] More specifically, each side cover 54 has a flat insert piece 541 integrally formed thereon, which protrudes toward one end of the case 53, as shown in Figure 5. The insert piece 541 protrudes downward from the upper side cover 54 of the pair of side covers 54, and protrudes upward from the lower side cover 54. In addition, the insert piece 541 has a projection 542 that bends in the thickness direction. The side cover 54 can be fixed to the case 53 by inserting the insert piece 541 of each side cover 54 into the corresponding opening of the case 53 and fitting the projection 542 into the mounting hole 530 that penetrates in the thickness direction and is provided in the third flat plate 534 of the case 53. Specifically, the upper side cover 54 is fixed to the case 53 by inserting the insertion piece 541 of the upper side cover 54 into the opening at the upper end of the case 53 and fitting the projection 542 into the mounting hole 530 provided at the upper end of the third flat plate 534, thereby closing the opening at the upper end of the case 53. Similarly, the lower side cover 54 is fixed to the case 53 by inserting the insertion piece 541 of the lower side cover 54 into the opening at the lower end of the case 53 and fitting the projection 542 into the mounting hole 530 provided at the lower end of the third flat plate 534, thereby closing the opening at the lower end of the case 53.

[0033] As shown in Figure 4, each side cover 54 is provided with a cylindrical shaft portion 543 that protrudes outward in the vertical direction D1. The shaft portion 543 protrudes upward on the upper side cover 54 of the pair of side covers 54, and protrudes downward on the lower side cover 54. In addition, a pair of power supply lines 521 and a connector 522, one end of which is connected to a pair of electrodes on the substrate 51, are led out from the shaft portion 543 of one of the pair of side covers 54 (in this case, the upper side) to the outside of the case 53.

[0034] In this embodiment, as shown in Figure 3, each lighting device 5 is positioned between two transparent plates 411 of the window section 41. In other words, one or more lighting devices 5 are positioned between a pair of adjacent transparent plates 411 in the thickness direction (front-to-back direction D3) among the multiple transparent plates 411. This eliminates the need for a waterproof structure for each lighting device 5, and also eliminates the need for countermeasures in case of contact with a person's hand or an object (in this case, a product), thus making it easier to realize a simple structure with reduced costs. The reasons for this will be explained below.

[0035] In the temperature control device 1, condensation may occur due to the temperature difference between the inside and outside of the storage body 2 caused by opening and closing the door 4. For this reason, if lighting devices are placed on the support columns, for example, it is necessary to give the lighting devices a waterproof function to prevent water droplets from entering the inside of the lighting devices. In contrast, in this embodiment, each lighting device 5 is placed in the space between two transparent plates 411, and since water droplets do not enter this space in the first place, it is not necessary to give each lighting device 5 a waterproof function. Also, if lighting devices are placed on the support columns, for example, the lighting devices are exposed inside the storage body 2, so there is a possibility that the lighting devices may be damaged or detached if they come into contact with a person's hand or an object (in this case, merchandise). In contrast, in this embodiment, each lighting device 5 is placed in the space between two transparent plates 411, and since people's hands or objects do not enter this space in the first place, the above problem does not occur, and no countermeasures are needed in case people's hands or objects come into contact with each lighting device 5.

[0036] Furthermore, in this embodiment, as shown in Figure 3, each lighting device 5 is positioned close to the frame 42, such that when the door 4 is in the closed position, the mounting surface (illumination surface) of each light source 55 on the substrate 51 faces the inside of the storage body 2. More specifically, each lighting device 5 is positioned so that when the door 4 is in the closed position, the illumination surface faces the center of the storage body 2 in the left-right direction D2. Therefore, each lighting device 5 can uniformly illuminate the inside of the storage body 2, centering on the center of the storage body 2 in the left-right direction D2. In Figure 3, the dashed lines extending from the mounting surface of each light source 55 represent the range of illumination light emitted by each light source 55.

[0037] Furthermore, in this embodiment, as shown in Figure 3, one of the two lighting devices 5 is positioned at one end of the window section 41 in the left-right direction D2, and the other lighting device 5 is positioned at the other end of the window section 41 in the left-right direction D2. Specifically, the left lighting device 5 is positioned at the corner formed by the left end of the frame 42 and the front transparent plate 411. The right lighting device 5 is positioned at the corner formed by the right end of the frame 42 and the front transparent plate 411. In other words, the multiple lighting devices 5 are positioned at both ends of the window section 41 in the width direction (left-right direction D2). As a result, each lighting device 5 is positioned in a relatively inconspicuous location at both ends of the window section 41 in the width direction. Therefore, a person looking inside the storage body 2 through the window section 41 will not have their visibility obstructed by the lighting devices 5, and the objects inside the storage body 2 (in this case, goods) will be easier to see.

[0038] The following describes how to attach each lighting device 5 to the door body 4. As shown in Figure 7, a pair of first mounting holes 422 into which the shaft portion 543 of the lighting device 5 can be inserted are provided on the lower surface of the upper end of the frame 42 of the door body 4. In this embodiment, the pair of first mounting holes 422 are provided at both ends in the width direction (left-right direction D2) of the upper end of the frame 42. Although not shown, a pair of second mounting holes are also provided on the upper surface of the lower end of the frame 42 of the door body 4. In this embodiment, the pair of second mounting holes are provided at both ends in the width direction (left-right direction D2) of the lower end of the frame 42. In addition, each first mounting hole 422 is provided with a connection portion (not shown) into which the connector 522 of the power supply unit 52 can be connected. By connecting the connector 522 to this connection portion, the lighting device 5 is electrically connected to a circuit (not shown) provided inside the frame 42.

[0039] To attach the lighting device 5 to the door body 4, first, the connector 522 of the power supply unit 52 of the lighting device 5 is inserted into the first mounting hole 422 of the door body, and the shaft portion 543 of the upper side cover 54 is inserted into the first mounting hole 422. Then, the shaft portion 543 of the lower side cover 54 is inserted into the second mounting hole of the door body 4. This attaches the lighting device 5 to the frame 42 of the door body 4.

[0040] [2] Example of power supply The following describes examples of power supply from the power supply unit of the storage unit 2 to the lighting device 5. Note that the first to third power supply examples shown below are just examples, and other configurations are acceptable as long as power can be supplied from the power supply unit to the lighting device 5.

[0041] (1) Example of first power supply In the first power supply example, as shown in Figure 8, a pair of first contact plates 423 are arranged on the frame 42 of the door body 4 at the portion that contacts the support column 22 when the door body 4 is in the closed position. In the example shown in Figure 8, the pair of first contact plates 423 are arranged so as to be aligned vertically D1 at the upper left end of the frame 42. One of the pair of first contact plates 423 is electrically connected to the anode of each lighting device 5 via a first wiring (not shown) built into the frame 42. The other first contact plate 423 is electrically connected to the cathode of each lighting device 5 via a second wiring (not shown) built into the frame 42.

[0042] Furthermore, the pair of first contact plates 423 contact the pair of second contact plates 221 (see Figure 9) located on the support column 22 when in the closed position, thereby electrically connecting them to the pair of second contact plates 221 on the support column 22 side. The pair of second contact plates 221 on the support column 22 side are electrically connected to the power supply unit provided in the storage unit 2. Therefore, in the first power supply example, at least one of the one or more lighting devices 5 (in this case, all of the lighting devices 5) changes its illumination state in accordance with the opening and closing of the door body 4. In Figure 9, the dashed lines extending from each lighting device 5 represent the range of illumination light emitted by each light source 55.

[0043] Specifically, when the door body 4 is in the closed position, as shown in the <closed position> of Figure 9, a pair of first contact plates 423 on the door body 4 side contact a pair of second contact plates 221 on the support column 22 side. As a result, power is supplied from the power supply unit to each of the contact plates 221, 423, the circuit inside the frame 42, and the power supply unit 52 to each of the lighting devices 5, causing each of the lighting devices 5 to light up.

[0044] On the other hand, when the door 4 is in the open position, as shown in the <open position> of Figure 9, the pair of first contact plates 423 on the door 4 side separate from the pair of second contact plates 221 on the support column 22 side, interrupting the power supply path from the power supply unit through each contact plate 221, 423. As a result, power is not supplied to each lighting device 5, and each lighting device 5 turns off. Thus, in the first power supply example, the lighting state of all lighting devices 5 changes with the opening and closing of the door 4.

[0045] As described above, in the first power supply example, when the customer opens the door 4 and takes out an object (in this case, a product) from inside the storage unit 2, each lighting device 5 is turned off. For this reason, the first power supply example has the advantage of being able to reduce power consumption more easily compared to the case where each lighting device 5 remains lit regardless of whether the door 4 is opened or closed.

[0046] (2) Second power supply example In the second power supply example, as shown in Figure 10 (before insertion), a pair of wires 424 are arranged on the rear side (cabin body 2 side) of the upper end of the frame 42 of the door body 4 to electrically connect the circuit inside the frame 42 with the power supply unit provided in the cabinet body 2. A connector 425 is attached to one end of the pair of wires 424, and the other end is electrically connected to the power supply unit 52 of each lighting device 5 via the circuit inside the frame 42. In the example shown in Figure 10, each wire 424 is arranged such that the connector 425 is exposed to the outside of the frame 42 from near the shaft portion 421 provided at the upper end of the door body 4.

[0047] The support column 22 is provided with an insertion slot (not shown) into which the connector 425 can be inserted. Then, as shown in Figure 10 <After insertion>, when the connector 425 is inserted into the insertion slot, power is supplied from the power supply unit of the storage unit 2 to each lighting device 5 via the wiring 424, the circuit inside the frame 42, and the power supply unit 52, and each lighting device 5 lights up.

[0048] As described above, in the second power supply example, each lighting device 5 can be turned on by inserting the connector 425 into the socket, and each lighting device 5 can be turned off by removing the connector 425 from the socket. Therefore, the second power supply example has the advantage that each lighting device 5 can be easily turned off when the lighting inside the storage unit 2 is not needed.

[0049] (3) Third power supply example <Viewpoint 1> in Figure 11 is a schematic perspective view of the door body 4 and the lighting device 5 attached to the door body 4, viewed from above. In the third power supply example, as shown in <Viewpoint 1> in Figure 11, a pair of electrode pins 421a protruding upward from the top surface are provided on the shaft portion 421 located at the upper end of the frame 42 of the door body 4. Each of the pair of electrode pins 421a is electrically connected to the power supply section 52 of each lighting device 5 via a circuit within the frame 42.

[0050] <Viewpoint 2> in Figure 11 is a schematic perspective view from below of the opening 20 of the storage body 2, the door body 4, and the lighting device 5 attached to the door body 4. Inside the storage body 2, as shown in <Viewpoint 2> in Figure 11, there is a shaft hole 222 into which the shaft portion 421 is inserted. Inside the shaft hole 222 is a cylindrical body 223 that can rotate independently, and on the lower surface of this cylindrical body 223 there is a pair of pin insertion holes 223a into which the pair of electrode pins 421a are inserted. By inserting the pair of electrode pins 421a into the pair of pin insertion holes 223a, power is supplied from the power supply unit of the storage body 2 to the pair of electrode pins 421a, the circuit inside the frame body 42, and the power supply unit 52, and each lighting device 5 lights up. Here, as described above, since the cylindrical body 223 is configured to rotate independently, the door body 4 can rotate around the shaft portion 421 even when the pair of electrode pins 421a are inserted into the pair of pin insertion holes 223a.

[0051] As described above, in the third power supply example, the shaft portion 421 of the door body 4 also serves as the power supply path from the power supply unit in the storage unit 2 to each lighting device 5. Therefore, the third power supply example has the advantage that power can be supplied to each lighting device 5 simply by attaching the door body 4 to the storage unit 2.

[0052] [3] Example The following describes an embodiment of the temperature control device component 3 according to this embodiment. In this embodiment, the third power supply example is adopted as the power supply method from the power supply unit to each lighting device 5. Figure 12 is a schematic cross-sectional view of the opening 20 of the storage body 2, the door body 4, and the lighting device 5 attached to the door body 4, viewed from below. In Figure 12, the plane along the vertical direction D1 is the cross-section. In Figure 12, the dashed lines extending from each lighting device 5 represent the range of illumination light emitted by each light source 55.

[0053] In this embodiment, the lighting device 5, positioned on the side of the shaft portion 421 of the door body 4, is located directly below the shaft portion 421 of the door body 4. Furthermore, the lighting device 5 is positioned such that the shaft portion 543 of the side cover 53 is fixed to the axis 421a of the hinge inserted into the shaft portion 421 of the door body 4. In other words, in the lighting device 5, the shaft portion 543 of the side cover 53 and the axis 421a of the hinge of the door body 4 are coaxial. The door body 4 moves between the closed position and the open position around the axis 421a of the hinge, and therefore its position is fixed regardless of whether the door body 4 is opened or closed. Accordingly, as shown in the <closed position> and <open position> in Figure 12, the lighting device 5, whose shaft portion 543 of the side cover 53 is fixed to the axis 421a of the hinge of the door body 4, also has its position fixed regardless of whether the door body 4 is opened or closed.

[0054] Therefore, as shown in Figures 9 and 12, the orientation of the illumination surface of the lighting device 5 does not change regardless of the rotation angle of the door body 4, and the illumination surface is directed toward the center of the storage body 2 in the left-right direction D2 (see the lighting device 5 on the right in Figure 9). In other words, at least one of the one or more lighting devices 5 (here, the lighting device 5 on the right, located on the hinge axis 421a side of the door body 4) directs the illumination direction toward the storage body 2 in the same direction whether the door body 4 is in the closed position or the open position. This has the advantage of making it easier to maintain illumination toward the storage body 2 regardless of whether the door body 4 is open or closed. Note that when the third power supply example is adopted, the pair of first contact plates 423 on the door body 4 side and the pair of second contact plates 221 on the support column 22 side in Figure 9 do not exist. Therefore, when the third power supply example is adopted, each lighting device 5 remains lit even in the <open position> in Figure 9.

[0055] Furthermore, as shown in Figures 9 and 12, the lighting device 5 positioned on the hinge axis 421a side of the door body 4 has its illumination surface directed towards the center of the storage body 2 in the left-right direction D2, regardless of the rotation angle of the door body 4. In other words, at least one of the one or more lighting devices 5 (in this case, the lighting device 5 positioned on the hinge axis 421a side of the door body 4) illuminates the interior of the storage body 2 whether the door body 4 is in the closed position or the open position. As a result, the interior of the storage body 2 is always illuminated regardless of whether the door body 4 is open or closed, which has the advantage of making it easier to ensure the visibility of objects (in this case, goods) stored inside the storage body 2.

[0056] On the other hand, in this embodiment, the lighting device 5 positioned on the handle 43 side of the door body 4 is not fixed to the hinge shaft 421a of the door body 4. Therefore, when the door body 4 is in the closed position, the lighting device 5 directs its illumination towards the center of the storage body 2 in the left-right direction D2, while when the door body 4 is in the open position, the illumination direction is directed to a different location from the center of the storage body 2 in the left-right direction D2 (see the lighting device 5 on the left in Figure 9). In other words, at least one of the one or more lighting devices 5 (here, the lighting device 5 positioned on the handle 43 side of the door body 4) changes its illumination direction relative to the storage body 2 depending on whether the door body 4 is in the closed or open position. This has the advantage of making it easier to illuminate the storage body 2 in a manner corresponding to the opening and closing of the door body 4.

[0057] [4] Advantages The advantages of the temperature control device component 3 according to this embodiment will be explained below with reference to Figure 13. In Figure 13, the lighting device A1 shown by the dashed line is the lighting device A1 in the temperature control device component of the comparative example. Unlike the lighting device 5 according to this embodiment, the lighting device A1 of the comparative example is positioned on the support column 22 and illuminates the inside of the storage body 2.

[0058] As shown in Figure 13, the lighting device A1 of the comparative example is positioned on the support column 22, resulting in a relatively short distance from the lighting device A1 to the objects (in this case, the goods) inside the storage body 2. Therefore, the lighting device A1 of the comparative example has the problem of difficulty in uniformly illuminating the inside of the storage body 2, such as areas inside the storage body 2 that are not reached by light. In contrast, in the temperature control device component 3 of this embodiment, the lighting device 5 is positioned on the door body 4 instead of the support column 22, so the distance from the lighting device 5 to the objects inside the storage body 2 can be increased compared to the lighting device A1 of the comparative example. Therefore, the temperature control device component 3 of this embodiment has the advantage that the lighting device 5 can easily illuminate a relatively wide area inside the storage body 2, making it less likely for areas inside the storage body 2 to be unlit and making it easier to uniformly illuminate the inside of the storage body 2.

[0059] Furthermore, in the temperature control device component 3 according to this embodiment, since the lighting device 5 is located on the door body 4 instead of the support column 22, there is also the advantage that the area around the door body 4 can be illuminated when the door body 4 is in the open position.

[0060] (Embodiment 2) Embodiment 2 of this disclosure will be described below with reference to the attached drawings. Embodiment 2 described below is an example that embodies this disclosure and is not intended to limit the technical scope of this disclosure.

[0061] Furthermore, in the cross-sectional view among the attached drawings, hatching of the fracture surface has been omitted in principle. In addition, in the following, explanations of points common to Embodiment 1 will be omitted as appropriate.

[0062] [1] Configuration of components for temperature control device In this embodiment, the temperature control device component 30 differs from the temperature control device component 3 in Embodiment 1 in that, as shown in Figure 14, it is equipped with one or more light sources 6 instead of one or more lighting devices 5. The one or more light sources 6 are arranged in the window portion 41 of the door body 4 and illuminate the inside of the storage body 2 at least when the door body 4 is in the closed position.

[0063] Each light source 6 is, for example, an LED element. However, each light source 6 is not limited to LED elements; it may also be other light-emitting elements such as semiconductor lasers, or EL elements such as organic EL elements or inorganic EL elements.

[0064] In this embodiment, each light source 6 is supplied with power via a power supply medium 7 that is less visible than the objects (in this case, the goods) placed inside the storage unit 2. Specifically, each light source 6 is supplied with power from the power supply unit of the storage unit 2 via a transparent conductive film 71 which serves as the power supply medium 7. More specifically, in this embodiment, the power supply medium 7 (conductive film 71) is a power supply path placed in the window 41 and is transparent. This has the advantage that a person looking inside the storage unit 2 through the window 41 does not have their visibility obstructed by the power supply medium 7, making it easier to see the objects (in this case, the goods) inside the storage unit 2.

[0065] Here, "lower visibility than objects placed inside the storage unit" includes the fact that the power supply medium 7 is transparent and invisible to humans, so when a person looks inside the storage unit 2 through the window 41, they can see the objects inside the storage unit 2, but not the power supply medium 7. Also, "lower visibility than objects placed inside the storage unit" includes the fact that the power supply medium 7 is very small and difficult for humans to see, so when a person looks inside the storage unit 2 through the window 41, they can see the objects inside the storage unit 2, but not the power supply medium 7, or hardly see it at all. Furthermore, "lower visibility than objects placed inside the storage unit" includes the fact that the power supply medium 7 is electromagnetic waves, etc., and is therefore invisible to humans, so when a person looks inside the storage unit 2 through the window 41, they can see the objects inside the storage unit 2, but not the power supply medium 7.

[0066] Furthermore, "difficult for humans to see" means, for example, that a person can recognize the power supply medium 7 when focusing on it, but cannot recognize that the power supply medium 7 is in their field of view when focusing on other components within their field of view. These other components include, for example, the window section 41 or objects inside the storage unit 2.

[0067] The conductive film 71 is a thin film made of a transparent conductive material such as ITO (Indium Tin Oxide). In this embodiment, the conductive film 71 is placed between a circuit provided inside the frame 42 and a light source 6, electrically connecting the circuit and the light source 6. Alternatively, the conductive film 71 can be placed between two or more different light sources 6, electrically connecting them. In other words, the conductive film 71 should be arranged to form a closed circuit including the power supply unit of the storage unit 2 and one or more light sources 6. As a result, each light source 6 is lit by power supplied from the power supply unit of the storage unit 2 via the conductive film 71.

[0068] In this embodiment, as shown in Figure 15, each light source 6 and each conductive film 71 are arranged between two transparent plates 411 of the window portion 41. In other words, one or more light sources 6 are arranged between a pair of adjacent transparent plates 411 in the thickness direction (front-to-back direction D3) among the plurality of transparent plates 411. Specifically, each light source 6 is arranged in contact with the rear surface of the front transparent plate 411. Also, each conductive film 71 is arranged in contact with the rear surface of the front transparent plate 411. This eliminates the need for a waterproof structure for each light source 55, and also eliminates the need for countermeasures in case of contact by a person's hand or an object (in this case, a product), thus making it easier to realize a simple structure with reduced costs. The reason for this is the same as that described in Embodiment 1, so it will be omitted here.

[0069] Furthermore, in this embodiment, one or more light sources 6 are arranged to be scattered across the window portion 41. In other words, one or more light sources 6 are multiple light sources 6. At least some of the multiple light sources 6 are arranged separately from the other light sources 6. Here, "arranged separately from the other light sources" includes, for example, when some of the light sources 6 are arranged in a line with space between them, the other light sources 6 are arranged at a distance longer than the aforementioned space between at least one of the light sources 6.

[0070] Specifically, each light source 6 can be placed anywhere in the window section 41, and may be arranged in a line with gaps between them, or irregularly. As long as they are placed in the window section 41, their placement is not limited. For example, some of the light sources 6 may be concentrated in the upper right corner of the window section 41, while the other light sources 6 may be placed in locations other than the upper right corner of the window section 41. This makes it possible to place each light source 6 in a location desired by, for example, the manufacturer of the temperature control device component 30 or the user of the temperature control device component 30, thus increasing the degree of freedom in the lighting pattern for the inside of the storage unit 2. In addition, by efficiently placing each light source 6 only where it is desired to illuminate, power consumption can be easily reduced.

[0071] Furthermore, in this embodiment, as shown in Figure 14, some of the light sources 6 are positioned so as to overlap with one of the shelves 21 when the door 4 is in the closed position and the window 41 is viewed from the front. Specifically, in the example shown in Figure 14, three light sources 6 are arranged in a line in the left-right direction D2 on each shelf 21, and these light sources 6 are positioned facing the shelf 21 in the front-back direction D3. In other words, at least one of the one or more light sources 6 is positioned so as to overlap with the shelf 21 when viewed through the window 41. As a result, a person looking inside the storage unit 2 through the window 41 will not have their visibility obstructed by a light source 6 positioned to overlap with the shelf 21. Therefore, compared to the case where each light source 6 is positioned in a location that does not overlap with the shelf 21, there is an advantage in that the objects inside the storage unit 2 (in this case, goods) are easier to see.

[0072] The following describes examples of the arrangement of each light source 6 using Figures 16 and 17. Note that the arrangement examples of each light source 6 described below are just examples, and each light source 6 may be arranged in ways other than those shown in Figures 16 and 17.

[0073] Figure 16 shows an example of the arrangement of each light source 6. In Figure 16, "B1" schematically represents the power supply unit of the storage unit body 2. The same applies to Figure 17, which will be described later. As shown in Figure 16, some of the light sources 6 are arranged so as to overlap with the shelf board 21 when the door body 4 is in the closed position and the window section 41 is viewed from the front. Other light sources 6 are arranged so as not to overlap with the shelf board 21. The shape of each conductive film 71 can be any shape, for example, it may be square, triangular, or circular. For example, reducing the area of ​​the conductive film 71 can reduce the cost of the conductive film 71.

[0074] Figure 17 shows other arrangement examples of each light source 6. In Figure 17, "C1," "C2," and "C3" all represent circuits (in this case, series circuits) that include one or more light sources 6 and one or more conductive films 71. In this embodiment, each light source 6 is connected in series in each circuit, but they may also be connected in parallel, or a combination of series and parallel connections.

[0075] As shown in the first arrangement example in Figure 17, there may be only one series circuit (in this case, circuit "C1") connected to the power supply unit of the storage unit 2. Here, even if the area of ​​the conductive film 71 changes, it does not affect the amount of charge flowing through the conductive film 71. Therefore, as shown in the first arrangement example in Figure 17, by arranging the circuit in the center in the left-right direction D2 of the storage unit 2 and minimizing the area of ​​each conductive film 71, the cost of each conductive film 71 can be suppressed.

[0076] Furthermore, as shown in the <Second Arrangement Example> in Figure 17, multiple circuits (here, circuits "C1", "C2", and "C3") may be arranged so as to be connected in parallel to the power supply unit provided by the storage unit 2. In this example, by arranging circuits "C1", "C2", and "C3" at the left end, center, and right end of the storage unit 2 in the left-right direction D2, it becomes easier to illuminate the inside of the storage unit 2 uniformly.

[0077] Furthermore, as shown in the <Third Arrangement Example> in Figure 17, multiple circuits (here, circuits "C1", "C2", and "C3") may be arranged irregularly according to the size of the objects (here, the goods) inside the storage unit 2, the arrangement of the shelves 21, etc. In this example, similar to the <Second Arrangement Example>, circuits "C1", "C2", and "C3" are arranged to be connected in parallel to the power supply unit provided by the storage unit 2. On the other hand, in this example, circuit "C1" is located at the left end of the storage unit 2 in the left-right direction D2, and circuits "C2" and "C3" are located at the right end of the storage unit 2 in the left-right direction D2. In this way, in this embodiment, it is possible to flexibly arrange each light source 6 according to the situation of the storage unit 2.

[0078] [2] Example of power supply In this embodiment, the power supply from the power supply unit of the storage unit 2 to each light source 6 can be any of the first to third power supply examples of Embodiment 1. Of course, any configuration other than the first to third power supply examples is acceptable as long as power can be supplied from the power supply unit to each light source 6. Below, only the differences between each power supply example and Embodiment 1 will be described, and the common points will be omitted from the explanation.

[0079] (1) Example of first power supply In the first power supply example, one of the pair of first contact plates 423 is electrically connected to the anode of the circuit including each light source 6 via a first wiring built into the frame 42. The other first contact plate 423 is electrically connected to the cathode of the same circuit via a second wiring built into the frame 42. When the door body 4 is in the closed position, as shown in the <closed position> of Figure 9, the pair of first contact plates 423 on the door body 4 side contact the pair of second contact plates 221 on the support column 22 side. As a result, power is supplied from the power supply unit to each contact plate 221, 423 and to each light source 6 via the circuit in the frame 42, and each light source 6 lights up. On the other hand, when the door body 4 is in the open position, as shown in the <open position> of Figure 9, the pair of first contact plates 423 on the door body 4 side separate from the pair of second contact plates 221 on the support column 22 side, interrupting the power supply path from the power supply unit to each contact plate 221, 423. As a result, power is not supplied to each light source 6, and each light source 6 turns off.

[0080] (2) Second power supply example In the second power supply example, a connector 425 is attached to one end of a pair of wires 424, and the other end is electrically connected to a circuit including each light source 6 via a circuit inside the frame 42. Then, as shown in Figure 10 <After insertion>, by inserting the connector 425 into the socket, power is supplied from the power supply unit of the cabinet body 2 to each wire 424 and to each light source 6 via the circuit inside the frame 42, and each light source 6 lights up.

[0081] (3) Third power supply example In the third power supply example, the pair of electrode pins 421a are electrically connected to the circuit containing each light source 6 via the circuit inside the frame 42. Then, as shown in <Viewpoint 2> of Figure 11, by inserting the pair of electrode pins 421a into the pair of pin insertion holes 223a, power is supplied from the power supply unit of the cabinet body 2 to the pair of electrode pins 421a and to each light source 6 via the circuit inside the frame 42, causing each light source 6 to light up.

[0082] [3] Advantages The advantages of the temperature control device component 30 according to this embodiment will be described below. In the temperature control device component 30 according to this embodiment, each light source 6 is located in the window portion 41 of the door body 4 rather than on the support column 22, so the distance from each light source 6 to the objects inside the storage body 2 can be increased compared to the lighting device A1 of the comparative example. Therefore, in the temperature control device component 30 according to this embodiment, each light source 6 can easily illuminate a relatively wide area inside the storage body 2, so there is less chance of areas inside the storage body 2 not being illuminated, and the storage body 2 can be illuminated uniformly, which is an advantage. In addition, in the temperature control device component 30 according to this embodiment, each light source 6 is located in the window portion 41 rather than on the frame 42 of the door body 4. Therefore, compared to the case where the inside of the storage body 2 is illuminated from the frame 42, it is easier to directly illuminate the objects inside the storage body 2 (in this case, products) with each light source 6, which is an advantage as it is easier to improve the visibility of the objects.

[0083] (modified version) The following lists some modifications of the embodiment. The modifications described below can be combined and applied as appropriate.

[0084] In the above embodiment 1, each lighting device 5 is positioned between a pair of adjacent transparent plates 411 in the thickness direction (front-to-back direction D3) of the window section 41, but is not limited to this. For example, each lighting device 5 may be positioned on the inside of the window section 41 (in other words, on the side of the transparent plate 411 that faces the storage body 2), or on the outside of the window section 41 (in other words, on the side of the transparent plate 411 that faces the storage body 2). Furthermore, when each lighting device 5 is positioned in this manner, the window section 41 may be composed of a single transparent plate 411 rather than a multi-layer structure consisting of multiple transparent plates 411.

[0085] In the above embodiment 2, each light source 55 is positioned between a pair of adjacent transparent plates 411 in the thickness direction (front-to-back direction D3) of the window section 41, but is not limited to this. For example, each light source 6 may be positioned inside the window section 41 (in other words, on the side of the transparent plate 411 that faces the storage body 2), or outside the window section 41 (in other words, on the side of the transparent plate 411 that faces the storage body 2). Furthermore, when each light source 55 is positioned in this manner, the window section 41 may be composed of a single transparent plate 411 rather than a multi-layer structure consisting of multiple transparent plates 411.

[0086] In the above embodiment 2, a transparent conductive film 71 is used as the power supply medium 7, but it is not limited to this. For example, a fine wire with a diameter in the micrometer range may be used as the power supply medium 7 instead of the transparent conductive film 71. The diameter of the wire is preferably 500 μm or less. More preferably, the diameter of the wire is 400 μm or less, 300 μm or less, 200 μm or less, 100 μm or less, and even more preferably 10 μm or less.

[0087] Furthermore, for example, by using contactless power supply from the power supply unit of the storage unit 2 to each light source 6, electromagnetic waves or the like may be used as the power supply medium 7 instead of the transparent conductive film 71. In this case, a transmitting antenna may be provided on the frame 42 and a receiving antenna on each light source 6. Contactless power supply may be an electromagnetic induction method, an electric field coupling method, or an electromagnetic wave method. Also, when using contactless power supply as the power supply method, for example, an electromagnetic shielding film may be attached to both sides of the window portion 41 of the door body 4 in the thickness direction (front-to-back direction D3). By attaching an electromagnetic shielding film in this way, it is possible to increase the intensity of the electromagnetic waves used in contactless power supply while suppressing leakage of electromagnetic waves to the outside.

[0088] In the first power supply example of Embodiment 1 described above, each lighting device 5 is lit when the door body 4 is in the closed position and turned off when the door body 4 is in the open position, but it is not limited to this. For example, each lighting device 5 may be lit when the door body 4 is in the closed position and blink when the door body 4 is in the open position. Alternatively, for example, each lighting device 5 may be lit so that the illuminance is higher when the door body 4 is in the closed position and so that the illuminance is lower when the door body 4 is in the open position. The same applies to Embodiment 2 described above.

[0089] In embodiments 1 and 2 described above, the door body 4 is a hinged door, but it is not limited to this. For example, the door body 4 may be a sliding door that can slide between an open position and a closed position. In this case, the power supply method from the power supply unit of the storage body 2 in embodiment 1 to each lighting device 5 may be, for example, rail power supply. Similarly, the power supply method from the power supply unit of the storage body 2 in embodiment 2 to each light source 6 may be, for example, rail power supply.

[0090] In each of the above embodiments, the temperature control device 1 is a reach-in display case such as a reach-in refrigerator or reach-in freezer, but is not limited thereto. The temperature control device 1 only needs to be temperature-controlled so that the temperature inside the case is maintained within a predetermined range, and may be, for example, a fixture with a door that can display products that are kept at a high temperature.

[0091] In each of the embodiments described above, the object subject to temperature control is, for example, a product sold in a commercial facility such as a convenience store or supermarket, but is not limited to this. The object subject to temperature control may also be, for example, a chemical or material that needs to be maintained at a constant temperature in a research facility.
