  As described above, the conventional see-through vending machine is configured by a rectangular parallelepiped housing having four sides in its entirety, and since the heat-insulating transparent panel is disposed only on the front surface of the housing, the vending machine is stored inside. Some of the items for sale cannot be seen without standing in front. In other words, the stored articles can be seen through only from one direction, which is insufficient for obtaining a so-called amenity display effect.

  Many of the above-mentioned conventional see-through vending machines are configured on the assumption that the back faces the wall.However, for example, as in convenience stores, product shelves are densely packed in a relatively narrow space. It is very difficult to secure a new space in front of the wall for installing the vending machine in the store where the vending machine is to be placed.

  In addition, since conventional see-through vending machines have been developed mainly for multi-product and multi-sale, the structure of holding and dispensing goods is complicated and large-scale. There is a problem that it becomes expensive in nature. At the same time, there was a problem that the appearance was uniform and the amenities were poor.

  Furthermore, the conventional vending machine has a structure in which most of the cooling device for cooling the articles in the refrigerator is arranged in a mechanical section separated from the article storage section. In addition to the storage unit, the cooling system also incorporates a cooling system such as a cooling cycle evaporator, a cool air duct, and an internal circulation fan, all of which are located deep inside the storage room away from the storage unit. Was contained. For this reason, it is difficult to uniformly and smoothly introduce and circulate cold air into the refrigerator, and there is a problem that the temperature of the product tends to vary.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a whole that includes a configuration for uniformly and smoothly cooling a stored article while being able to have an appearance excellent in amenity. It is an object of the present invention to provide a vending machine which can be constructed at low cost and can have a space-saving structure with a high degree of freedom in installation.

  The present invention is directed to a vending machine that stores a large number of articles in an article storage unit and discharges the articles to a payout slot every time the cash collection device detects the insertion of a predetermined amount of money. A transparent heat insulating panel forming a side surface of the article storage section, a heat insulating floor forming a bottom face of the article storage section, a heat-insulating canopy detachably attached to an upper surface of the article storage section, and an inside of the article storage section. A vending machine comprising: a drum-shaped multiple holder that is housed and holds a plurality of article rows outside in a circular array. Further, the present invention provides a vending machine for carrying out articles stored in an article storage section to a payout port based on a sales command for selling articles, a transparent heat insulating panel forming a side surface of the article storage section. A heat-insulating floor that forms the bottom surface of the article storage section and has an article drop hole; a detachable heat-insulating lid that forms the top face of the article storage section; a rotating body that rotates about a vertical axis; A plurality of holders that rotate together with the rotating body while holding a plurality of article rows around the rotating body in the direction of the axis, and rotate based on the sales command, whereby the plurality of article rows And a rotating holder member for carrying out any one of the articles from the article pit to the payout port. In this vending machine, it is also possible to provide a fan that is arranged inside the multiple holder and circulates between the outside and the inside of the multiple holder by blowing air upward. Furthermore, it is also possible that the heat-insulating floor is a double floor having a layered space, and the air blown up by the fan is circulated from the outside to the inside of the multiple holder through the layered space. .

  According to the vending machine, the interior of the article storage section can be seen through from multiple directions, so that an appearance excellent in amenity can be provided. In addition, a fan for ventilating (for example, cooling or heating) the sales items in the article storage unit can be arranged in the space of the article storage unit, and functions as a circulation duct for ventilation on the heat insulating floor of the article storage unit. As a single-type vending machine, the whole structure including a structure for uniformly and smoothly ventilating stored items can be configured at low cost, and a space-saving structure with a high degree of freedom in installation can be provided. Can be.

  Further, the multiple holder may be configured to be driven to rotate to sequentially carry out the articles in the article storage section to the payout port based on a sales command for selling articles.

  Further, the vending machine may include a storage section for storing articles inside the multiple holder. According to this vending machine, for example, articles to be stored in the article storage section can be stored in the storage section. Therefore, for example, the worker can store more articles than are sold in the vending machine, so that workability such as replenishment of articles is improved. Further, since an effect of cooling or heating can be obtained even inside the multiple holder, articles can be stored while being held at a temperature close to an appropriate temperature at the time of sale. Therefore, the articles replenished by being moved from the storage section to the article storage section can be sold relatively quickly. Therefore, the sales volume per unit time of the vending machine is improved.

  ADVANTAGE OF THE INVENTION According to this invention, while providing the appearance excellent in the amenity property, the vending machine which was able to comprise the whole at low cost and was able to be a space saving structure with a high degree of freedom in installation is provided. can do.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an external configuration of a vending machine according to an embodiment of the present invention.
FIG. 2 shows a part of the exterior of the vending machine removed.

  The vending machine 10 shown in FIG. 1 is configured so as to form a tower-shaped casing 11 having a regular hexagonal (polygonal) column shape. The housing 11 includes a regular hexagonal (polygonal) base 21, six (plural) struts 22 erected vertically from respective apexes of the regular hexagonal base 21, and a plurality of struts 22. The entire structural frame (framework) is formed by a regular hexagonal upper frame member (heat insulating lid) 23 whose upper ends are respectively restrained and fixed on the vertices of the regular hexagon.

  The upper frame member 23 is formed of a resin (plastics) integrally molded product to provide heat insulation, and a circular window frame portion is formed inside the upper frame member 23. A heat-insulating disc-shaped canopy 24 is fitted to the window frame from above. A locking mechanism (not shown) is incorporated in the canopy (insulated lid) 24, and a locking / unlocking operation can be performed by inserting a specific key through a keyhole 25 provided at the center of the upper surface (outer surface). It has become. While the canopy 24 is locked to the upper frame member 23 by locking, the locking is released by unlocking and becomes detachable.

  An article storage unit 12 occupying the main space of the vending machine 10 is disposed at an upper portion of the housing 11. A machine room 13 is arranged below the article storage unit 12. In the machine room 13, a compressor and a condenser (condenser) of the cooling cycle 30 are incorporated. Further, a money receiving device 33 and an article payout port 34 are arranged in the machine room 13. The article storage section 12 and the machine room 13 are partitioned by a double floor (insulated floor) 40. Note that a sales button (not shown) described later may be provided instead of the money collection device 33.

  The double floor 40 is configured with a layered space interposed between the heat insulating plate 41 and the floor plate 44. In this case, the heat insulating plate 41 is disposed on the machine room 13 side, and the floor plate 44 is disposed on the article storage unit 12 side. With such a structure, the double floor 40 forms a heat-insulating floor with good mechanical strength and good heat-insulating properties. The article storage unit 12 is thermally insulated from the machine room 13 by the double floor 40. The base 21, the double floor 40, and the upper frame member 23 each have a regular hexagonal (polygonal) outline in which vertices and sides overlap each other.

  The article storage section 12 is surrounded by six transparent heat-insulating panels 35 that respectively close the columns 22, thereby forming a regular hexagonal prism-shaped heat-insulating chamber (insulated space) inside. The upper part of the heat insulating chamber is covered and insulated by the canopy 24, and the bottom surface is insulated by the double floor 40. As the transparent heat insulating panel 35, a so-called pair glass in which an insulating air layer is interposed between two (a plurality of) glasses is preferable. Paired glass is less likely to be fogged by a temperature difference, and has good heat insulation and transparency. If a ribbon or film-shaped electric heater is attached to a part of the paired glass and a weak electric power is supplied to the electric heater to always heat the heater, good transparency can be always ensured.

  The machine room 13 is surrounded by a metal side plate 36 such as a steel plate to form a regular hexagonal storage space inside. The side plate 36 is appropriately provided with a ventilation slit or the like for releasing heat radiation from the condenser. The outside of the machine room 13 has a regular hexagonal column shape that is substantially flush with the outside of the article storage unit 12, but one side of the window is opened, and the article payout port 34 and the money collection device 33 or a sales Buttons (not shown).

FIG. 3 shows the components of the article storage section 12 in an extracted state.
In the same figure, the double floor 40 shows only the heat insulating plate 41 under the floor plate 44 (FIG. 2). The heat insulating plate 41 is made of a thick and rigid hard foamed resin, and the main surface except for the edge is formed with a flat concave bottom 42 so that a layered space is formed when the floor plate 44 is stacked thereon. Has become. The concave bottom surface 42 has a flat convex surface portion 43 formed in an island shape, which functions as a spacer for supporting the floor plate 44 flat. The contour of the heat insulating plate 41 is a regular hexagon overlapping the base 21, and an oval article drop hole 45 is formed along one side of the regular hexagon. The drop hole 45 is a drop passage to the article discharge port 34, and is formed in the same shape at the corresponding position of the floor plate 44.

  A spring-return type one-way valve lid (not shown) is interposed below the article drop hole 45. The valve lid is automatically opened by the weight of the article 50 only in the direction from the pit 45 to the article payout port 34, but otherwise is always closed by the bias of the spring.

  As shown in FIG. 3, each transparent heat insulating panel 35 surrounding the side surface of the heat insulating chamber is sandwiched between the columns 22 by side frame members (sashes) 46 and 47. The column 22 is made of a steel plate formed in a bar shape having a V-shaped cross section. The side frame members 46 and 47 are formed by the outer frame member 46 and the inner frame member 47. Each of the two frame members has a bar shape having a uniform cross-sectional shape, and is fitted slidably in the longitudinal direction along the inside and outside of the column 22 having the V-shaped cross section. Both ends of the transparent heat insulating panel 35 are vertically slidably held between the two frame members 46 and 47. The outer frame member 46 is formed by using an extruded aluminum product in order to provide both appearance (aesthetic appearance) and rigidity and strength. The inner frame member 47 is formed using a resin extruded product in order to obtain the effects of heat insulation and cushioning.

  FIG. 4 is a perspective view of the upper frame member 23 described above. FIG. 5 is a perspective view of the canopy 24 covering the window frame portion of the upper frame member 23. As shown in the figure, the outside of the upper frame member 23 is a regular hexagon overlapping with the base 21 and the double floor 40, and the inside is a circular window frame portion into which the canopy 24 is fitted from above. . The canopy 24 covers the window frame and closes the upper part of the heat insulating chamber.

  FIG. 6 is a perspective view partially showing the inside of the entire vending machine 10 shown in FIG. 1 and FIG. In the figure, articles 50 which are products to be sold by a vending machine (for example, soft drink products such as cans, bottles, plastic bottles, etc.) are stacked vertically (three each) on the double floor 40. At the same time, the article rows are stored in a state of being arranged in a circle at intervals of 30 degrees. Thereby, in the example shown in the figure, up to 3 × 12 columns = 36 can be stored. As described above, the double floor 40 has a double structure in which the floor plate 44 is superimposed on the heat insulating plate 41, and the upper surface thereof is flat and flat so that 50 rows of articles stacked vertically can slide. It is formed smoothly.

  On the central surface of the double floor 40, a drum-shaped multiple holder (rotary holder member) 51 is arranged in a state where the axis is vertically set. This multiple holder 51 is formed by assembling and assembling rectangular U-shaped metal channel members (holders) 52 in a circle, and the twelve channel members 52 face the U-shaped opening side outward. However, they are arranged in circles at intervals of 30 degrees. Each of the channel members 52 forms a row holder for holding the 50 rows of the articles from the side. Both ends of the rectangular U-shape are bent inward at substantially right angles to hold the 50 rows of articles, thereby holding and holding the articles 50 (bottles). The drum-shaped multiple holder 51 is mounted on the central surface of the double floor 40 so as to rotate horizontally. Each channel member 52 is formed by bending a metal plate (thin steel plate) into a rectangular shape.

  As described above, the compressor and the condenser of the cooling cycle 30 are disposed below the double bed 40. Further, a money receiving device 33 or a sales button (not shown) described later, an article payout port 34, and the like are provided. An automatic opening / closing tray 60 that is opened by gravity operation and closed by spring return is attached to the article discharge port 34. When the article 50 is dropped from the pit 45 of the double floor 40, the automatic opening / closing tray 60 is automatically pushed out by being pushed down by the weight of the article 50 so that the article 50 can be easily taken out. On the other hand, when the articles 50 are not dropped, they are raised by the constant action of the spring, and the article payout port 34 is automatically closed. In the same figure, the article drop hole 45 is hidden by the drop control plate 61.

  FIG. 7 is a perspective view partially showing the configuration in the vicinity of the article drop hole 45. As shown in the figure, a drop control plate 61 is provided upright near the outside of the article drop hole 45. The drop control plate 61 has an upper end projecting horizontally to the article row side, and the projecting part is interposed between the lowermost article and the second article of the articles 50 stacked vertically. Then, only the lowermost article is selectively dropped into the pit 45.

  FIG. 8 is a perspective view partially showing the multiple holder 51 and the inside thereof. As shown in the figure, first, as the channel material 52 constituting the multiple holder 51, a metal plate (thin steel plate) obtained by bending a metal plate (thin steel plate) into a channel shape having a substantially rectangular U-shaped cross section is used. Each of the channel members 52 is arranged in a circle with the bottom surface of the U-shape facing the center side, and is assembled into a drum shape.

  The channel members 52 are arranged in a circle while the U-shaped side surfaces are closely adjacent to each other, and assembled in a drum shape. Therefore, the U-shaped angle of each channel material 52 is not a right angle but is widened by 15 degrees wider than the right angle. That is, both sides of the U-shape are formed to open at an angle of 30 degrees (15 degrees + 15 degrees) from each other. Therefore, a cut-and-raised piece 53 that is cut and raised in a rectangular shape toward the inside of the U-shape is formed on one side plate portion of the U-shape. The cut-and-raised pieces 53 form a substantially right-angled U-shaped holder in each channel material 52.

  Each of the channel members 52 is provided with a horizontal cutout 54 at a position corresponding to the horizontal overhang of the drop control plate 61 (FIG. 7). The notch 54 is provided to prevent the multiple holder 51 from interfering with the horizontal overhang when the multiple holder 51 is horizontally rotated on the double floor 40, and has a width that does not hinder the holding of the article 50. It is provided in.

  An article drop hole 45 is provided in the double floor 40, and an article sensor 62 is provided in front of the article drop hole 45. The article sensor 62 detects whether an article is located at a fixed position before the pit 45. A mechanically operated switch such as a microswitch (also called a limit switch) is used as the article sensor 62, but may be, for example, an optical sensor or a touch sensor.

FIG. 9 shows an essential part of the multiple holder 51 in the cross-sectional direction.
FIG. 10 shows a main portion of the multiple holder 51 in the side surface direction.

  Although shown only partially in FIG. 8, the multiple holder 51 is assembled using an upper disc-shaped frame 70 and a lower annular frame 71 as shown in a cross section in FIG. As shown in FIG. 9, both frames 70 and 71 have outer contours formed in regular dodecagons (polygons), and each channel material 52 is fixed to each side of the regular dodecagon by screws. As a result, they are assembled into a circle in a state adjacent to each other and assembled in a drum shape. Note that FIG. 9 also shows a cross-sectional view of only the channel material 52 for understanding the drawing. As shown in FIG. 9, a large gear 72 is provided at the center of the upper disc-shaped frame 70. A through guide hole 73 is provided at the center axis position of the large gear 72. Further, the upper frame 70 and the lower frame 71 are provided with roller rings 74 and 75, respectively, in which guide rollers axially supported at fixed positions on the fixed side are inscribed. The rotating body of the present embodiment has a configuration that contributes to the rotation of the multiple holder 51, such as the upper disc-shaped frame 70, the lower annular frame 71, and the roller rings 74 and 75.

  8 and 10, the evaporator 31 and the cooling fan 32 of the cooling cycle 30 are disposed inside the multiple holder 51. The evaporator 31 forms part of the cooling cycle 30 and is connected to the condenser below the double bed 40 by piping. Heat exchange fins (not shown) are attached to the evaporator, and a cooling fan 32 (electric fan) is disposed above the heat exchange fins.

  The cooling fan 32 draws air from the lower part of the article storage unit 12 and passes the air through the heat exchange fins of the evaporator. The air (cool air) cooled by passing through the heat exchange fins is blown up above the cooling fan 32. The blown-up cool air circulates from the inner side to the outer side of the multiple holder 51 and cools the 50 rows of articles, and circulates to the lower part of the article storage unit 12, as indicated by arrows in FIG.

  As described above, the multiple holder 51 is formed by arranging a plurality of (12) channel members 52 in a circle and assembling them in a drum shape. As shown in FIG. A rectangular ventilation window 55 is formed in each of the lower surfaces so that cool air can flow through the ventilation window 55.

  A layered space portion is formed between the heat insulating plate 41 and the floor plate 44 forming the double floor 40, and the layered space portion communicates with the inside of the article storage section 12 through a ventilation hole provided in the floor plate 44. Although not shown, the ventilation holes are provided so as to form a ventilation duct between the outside and the inside of the multiple holder 51. The air that has cooled the article 50 from inside to outside of the multiple holder 51 circulates through the ventilation duct in the double floor 40 to the evaporator (cooler) 31 and is cooled again. Thus, the article 50 held outside the multiple holder 51 can be cooled uniformly.

  In this way, the cool air blown up by the fan 32 circulates from the ventilation window 55 to the outside of the multiple holder 51, and efficiently cools the articles stored outside the multiple holder 51 while storing the articles. It is circulated in the section 12.

  Further, since the thermal conductivity of the metal channel material 52 is good, the channel material 52 is also cooled by the cool air. The cooled channel material 52 uniformly cools the articles held inside the U-shape. In this way, the article group can be efficiently cooled with a small cooling capacity, that is, with a small power consumption.

  As shown in FIGS. 9 and 10, at least three roller wheels 81 are attached to the lower end of the multiple holder 51 at equal intervals. The multiple holder 51 is adapted to be mounted on the roller wheel 81 and horizontally rotated on the double floor 40 surface. That is, the roller wheel 81 functions as a kind of thrust bearing that rotatably supports the multiple holder 51 on the double floor 40.

  Each roller wheel 81 is mounted so as to rotate in the circumferential direction on the same circumference, and the outer circumference thereof is formed to be curved in an arc shape or a curved shape. According to this, the roller wheel 81 can smoothly roll in the circumferential direction while contacting the double floor 40 with a small contact area and a small rolling resistance. Thus, the multiple holder 51 can be smoothly and stably rotated in the horizontal direction on the double floor 40 surface with a relatively small driving force.

  On the other hand, as shown in FIGS. 8 and 10, a gate-shaped frame 82 forming an inverted U-shape is attached to the inside of the multiple holder 51. The frame member 82 is formed using a structural material such as a steel plate, and is fixed to the double floor 40 while straddling the condenser 31 and the cool air fan 32 inside the multiple holder 51. A motor 83 with a reduction gear (a so-called geared motor) is attached to the upper end of the frame 82. A small gear 84 is attached to the reduction output shaft of the motor 83 with gears, and the small gear 84 is meshed with the large gear 72 on the multiple holder 51 side.

  Further, guide rollers 85 and 86 that are inscribed in the upper and lower two roller rings 74 and 75 on the multiple holder 51 side are attached to the frame 82. Further, a positioning guide shaft 87 which is inserted into the through guide hole 73 of the large gear 72 projects vertically from the center of the upper end of the frame 82. By the guide shaft 87 and the guide rollers 85 and 86, the multiple holder 51 is positioned at the center in the article storage unit 12, and is guided so as to rotate in the horizontal direction in the positioned state. In this state, the article is driven to rotate while being held by the motor 83 with the reduction gear. The articles are swiveled in accordance with the rotation of the multiple holder 51 while being stacked vertically.

  FIGS. 11 to 14 are development views showing the article storage state of the vending machine 10 described above. In the drum-shaped multiple holder 51, 50 rows of articles in a stacked state are stored in a circular array, and the state of the circular array is shown in a plan view as shown in FIGS. The arrow in the drawing indicates the rotation direction of the multiple holder 51, that is, the turning movement direction of the article 50, and it is assumed that the leftmost article 50 moves to the rightmost end in the next movement step.

  In the figure, the multiple holder 51 is driven to rotate until the article sensor 62 detects an article. That is, when the sensor 62 detects any one of the articles 50, the motor 83 is stopped at the detected position, whereby the turning movement of the article 50 is also stopped. However, a continuous non-detection time detection timer is interposed in the drive circuit of the motor 83, and when the article sensor 62 does not continuously detect the article 50 for a predetermined time or longer, the timer controls the motor. The drive by 83 is stopped.

  Here, when the money collecting apparatus 33 detects the insertion of a predetermined amount of money (coins or the like) in a state where the article 50 is stored, the money collecting apparatus 33 issues a commodity payout command, and thereby, The motor 83 is driven, and the article 50 is turned. The driving of the motor 83 by detecting the money input is performed until the next article 50 comes to the detection position of the article sensor 62. That is, every time the money collecting apparatus 33 detects the insertion of the predetermined amount of money, the 50 rows of articles are turned on the double floor 40 by a fixed pitch. As a result, the article 50 sent out beyond the detection position of the sensor 62 falls into the drop hole 45 and is carried out (discharged) to the article discharge port 34, and the next article 50 is fed to the detection position just before the drop hole 45. Note that, in the above description, the sale of the article 50 is started by detecting the insertion of a predetermined amount of money, but the invention is not limited to this. For example, the vending machine 10 may be provided with an appropriate selling button (not shown) instead of the money collecting device 33. In this case, when the sales button is appropriately pressed, for example, by the user of the vending machine 10, a signal (sales command) to sell the article 50 is output from the sales button. As described above, if the vending machine 10 provided with the sale button for notifying the user that he or she wants the article 50 is installed in, for example, a conference room, the attendees of the conference can be cooled without paying money, for example. The article 50 as a beverage can be freely obtained.

  In this case, even if the articles 50 are stacked on the articles 50 sent to the pit 45, the above-described drop control plate 61 is interposed between the lowermost article 50 and the article 50 thereon, Only the lowermost one is dropped into the pit 45. As shown in FIGS. 11 and 12, for example, as shown in FIG. 11 and FIG. 12, when the next row of articles 50 is fed out by a certain pitch again upon detection of the next money input or press of the sales button, Each of them falls one step down in front of the pit 45.

  As described above, the articles 50 held in the multiple holder 51 are dispensed to the article dispensing port 34 one by one each time money is input or the sales button is pressed. Then, as shown in FIG. 14, when the last one held in the multiple holder 51 is paid out, the motor 83 is driven by the timer for at least a time sufficient for the multiple holder 51 to make one rotation, Stopped. The money collecting apparatus 33 is configured to interlock with the detection of the article sensor 62 and to accept money input only when the article 50 remains in the multiple holder 51.

  The replenishment of the articles 50 can be performed by opening the canopy 24 from above the article storage unit 12. At this time, the replenishment location of the article may be any location of the multiple holder 51. As shown in FIGS. 11 to 14, the articles 50 held by the multiple holder 51 can be dispensed without leaving any one at any position.

=== Container ===
As shown in FIG. 15, the surface forming the above-mentioned drum-shaped inside of the multiple holder 51 and the flat surface 88 a forming the uppermost portion in the inside portion are provided as a stocker for storing the articles 50 to be sold. (Accommodating section) 500 may be configured.

  Specifically, as shown in FIG. 16, a flat surface 88a and a side surface 88b having a predetermined height for supporting the flat surface 88a above the upper end of the positioning guide shaft 87 are formed. The stocker bottom 88 to be formed is appropriately fixed to the upper disc-shaped frame 70. The stocker bottom 88 and the inner surface of the metal channel material 52 form a stocker 500. Note that the article 50 can be appropriately stored in an appropriate place on the upper surface of the upper disc-shaped frame 70 without providing the stocker bottom 88. However, with the flat stocker bottom 88 described above, there are no obstacles such as the positioning guide shaft 87, and more articles 50 can be stored. Such a stocker 500 can accommodate the articles 50 to be stored in the article storage unit 12, for example. Therefore, for example, the worker can store the articles 50 more than sold in the vending machine 10, so that the workability such as replenishment of articles is improved. In addition, since the cooling effect can be obtained even inside the multiple holder 51 by the cool air indicated by the arrow in FIG. 16, the article 50 can be stored while being cooled to a temperature close to the appropriate temperature at the time of sale. Therefore, the articles 50 replenished by being moved from the stocker 500 to the article storage unit 12 can be sold relatively quickly. Therefore, the sales amount of the vending machine 10 per unit time is improved.

=== Other Embodiments ===
As described above, the present invention has been described based on the typical embodiments. However, the present invention can have various aspects other than those described above.

  For example, the horizontal cross-sectional shape of the transparent heat insulating panel 35 of the vending machine 10 may be a regular polygon other than a regular hexagon. However, in the case of a polygon having less than six corners, a wasteful space at the corner becomes large, and in the case of a polygon exceeding the hexagon, the number of parts such as the support 22 and the transparent heat insulating panel 35 increases, so that the space becomes large. A hexagon is optimal and desirable in terms of efficiency and rationality of configuration. The horizontal cross-sectional shape of the transparent heat insulating panel 35 is not limited to a regular polygon, but may be a general polygonal shape or a circular shape.
