  As shown in FIGS. 1, 2, and 4, the vending machine includes a Stirling refrigerator 20, a cooling unit 30, a heat radiating unit 40, and a cool / warm operation switching unit 50.

  The Stirling refrigerator 20 is placed horizontally in the machine room 15 of the main body cabinet 10 and includes a cold heat generation unit 21 that generates cold heat and a high heat generation unit 22 that generates high heat.

  The cooling unit 30 is disposed inside the machine room 15. This cooling unit 30 transfers the cold heat from the cold heat generating part 21 of the Stirling refrigerator 20 to a cooling container (container) 53 described later, and cools the air (internal atmosphere) inside the cooling container 53. Is.

  Such a cooling unit 30 includes a condensation heat exchanger 32, an evaporation heat exchanger (cooler) 33, a liquid supply pipe 34, and a gas supply pipe 35 as heat transfer means. A refrigerant is sealed in the condensation heat exchanger 32, the evaporation heat exchanger 33, the liquid supply pipe 34, and the gas supply pipe 35. The refrigerant is a non-freezing refrigerant such as carbon dioxide which is a gas at normal temperature and which is liquid by the cold heat of the cold heat generating unit 21 of the Stirling refrigerator 20.

  The condensation heat exchanger 32 is connected to the cold heat generating unit 21 of the Stirling refrigerator 20. In the condensing heat exchanger 32, the refrigerant that has been gas is liquefied by the cold generated by the cold heat generating unit 21 and becomes a condensed liquid.

  The evaporating heat exchanger 33 is accommodated in the cooling container 53 and is disposed at a position relatively lower than the condensing heat exchanger 32. In the evaporative heat exchanger 33, the refrigerant passing through the evaporative heat exchanger 33 is vaporized by the heat obtained from the air inside the cooling container 53. In other words, the air inside the cooling container 53, which is the peripheral region of the evaporative heat exchanger 33, is cooled as the refrigerant passing through the evaporative heat exchanger 33 evaporates.

  The liquid supply pipe 34 is made of a tubular member, and connects the inside of the condensation heat exchanger 32 and the inside of the evaporating heat exchanger 33. On the other hand, the gas supply pipe 35 is made of a tubular member and connects the inside of the condensation heat exchanger 32 and the inside of the evaporating heat exchanger 33 separately from the liquid supply pipe 34. The liquid supply pipe 34 and the gas supply pipe 35 are arranged so that the gas supply pipe 35 is located above the liquid supply pipe 34. Such an arrangement is because the density of the refrigerant passing through the gas supply pipe 35 is smaller than the density of the refrigerant passing through the liquid supply pipe 34. Then, the refrigerant condensed in the condensation heat exchanger 32 moves inside the liquid supply pipe 34 from the condensation heat exchanger 32 to the evaporating heat exchanger 33. Further, the refrigerant evaporated in the evaporating heat exchanger 33 moves inside the gas supply pipe 35 from the evaporating heat exchanger 33 to the condensing heat exchanger 32.

  The operation of the cooling unit 30 configured in this manner will be described. The refrigerant in the condensation heat exchanger 32 is cooled and liquefied by the low temperature generated in the cold heat generating unit 21 of the Stirling refrigerator 20. The liquefied refrigerant moves to the evaporation heat exchanger 33 through the liquid supply pipe 34. The refrigerant that has moved into the evaporative heat exchanger 33 is vaporized by the heat of the air inside the cooling container 53. At this time, the air inside the cooling container 53 is cooled by the heat removed from the refrigerant. The vaporized refrigerant moves to the condensation heat exchanger 32 through the gas supply pipe 35. The refrigerant that has moved to the condensation heat exchanger 32 is cooled again and liquefied by the low temperature of the cold heat generator 21. By repeating such a cycle, the air inside the cooling container 53 is cooled.

  The heat dissipation unit 40 is disposed inside the machine room 15. The heat dissipating unit 40 is for discharging the high heat generated in the high heat generating unit 22 of the Stirling refrigerator 20 to the outside of the main body cabinet 10.

A refrigerant is sealed in the first heat exchanger 41, the second heat exchanger 42, the first refrigerant supply pipe 43, and the second refrigerant supply pipe 44. For example, water is used as the refrigerant.

  The first heat exchanger 41 is connected to the high heat generation unit 22 of the Stirling refrigerator 20. The first heat exchanger 41 causes the internal refrigerant to receive high heat generated by the high heat generation unit 22.

  The second heat exchanger 42 is disposed at a position away from the Stirling refrigerator 20 by a certain distance. The second heat exchanger 42 radiates heat from the internal refrigerant. An outside fan 45 is disposed around the second heat exchanger 42. The outside blower fan 45 is for discharging the air around the second heat exchanger 42 to the outside of the main body cabinet 10.

  The first refrigerant supply pipe 43 is made of a tubular member, and connects the inside of the first heat exchanger 41 and the inside of the second heat exchanger 42. On the other hand, the second refrigerant supply pipe 44 is formed of a tubular member and connects the inside of the first heat exchanger 41 and the inside of the second heat exchanger 42 separately from the first refrigerant supply pipe 43. Although not shown in the figure, the second refrigerant supply pipe 44 is provided with a circulation pump, and by operating the circulation pump, the inside of the first heat exchanger 41, the first refrigerant supply pipe 43 , The refrigerant circulates in the second heat exchanger 42 and the second refrigerant supply pipe 44.

  The operation of the heat dissipation unit 40 configured in this way will be described. The refrigerant inside the first heat exchanger 41 receives the high temperature generated by the high heat generation unit 22 of the Stirling refrigerator 20 and is heated. The heated refrigerant moves to the second heat exchanger 42 through the first refrigerant supply pipe 43 by the action of the circulation pump. The refrigerant that has moved into the second heat exchanger 42 is cooled by being radiated by the second heat exchanger 42. At this time, the air around the second heat exchanger 42 is heated and heated by being radiated. The heated air is discharged to the outside of the main body cabinet 10 by the outside fan 45. The refrigerant cooled by the second heat exchanger 42 moves to the first heat exchanger 41 through the second refrigerant supply pipe 44. The refrigerant that has moved to the first heat exchanger 41 is heated again by the high temperature of the high heat generation unit 22. By repeating such a cycle, high heat generated in the high heat generation unit 22 is released to the outside of the main body cabinet 10.

  As shown in FIG. 2, the cold / warm operation switching unit 50 includes an internal fan (air fan) 51, an internal heater 52, a cooling container 53, and a shutter mechanism (opening / closing device) 54.

Further, the lower surface of the first plate member 5411 forms a closed surface 5414 that contacts the upper surface (wall surface) 147a of the bottom plate 147 of the product storages 141, 142, and 143 and covers and closes the suction port 18 and the discharge port 19. ing. On the other hand, the second plate-like member 5412 is formed to have a size larger than the cross-sectional area of the bottom duct 172 and capable of closing the space between the bottom duct 172 and the bypass duct 173.

  The moving means 542 is for moving the shutter 541 from the front side to the rear side or from the rear side to the front side, and has a support shaft 5421 and a guide rail 5422 as shown in FIGS. ing. The support shaft 5421 is provided to extend laterally from the side of the first plate-like member 5411 of the shutter 541. More specifically, a pair of left and right support shafts 5421 are provided coaxially on the front side of the first plate-like member 5411 and a pair of left and right sides are provided coaxially on the rear side of the first plate-like member 5411. The guide rail 5422 is provided corresponding to each support shaft 5421 and has a groove through which the support shaft 5421 is inserted. As shown in FIG. 7, the groove extends in the moving direction (front side / rear direction) of the shutter 541, and has one end (front end) and the other end (rear end). Forms an inclined portion 5422a inclined toward the upper surface (wall surface) 147a of the bottom plate 147 of the product storage containers 141, 142, 143, and the intermediate portion is the upper surface (wall surface) 147a of the bottom plate 147 of the product storage containers 141, 142, 143. The separation portion 5422b is formed along the upper surface (wall surface) 147a while being separated from the surface. Although not clearly shown in the figure, the moving unit 542 has a driving unit for moving the shutter 541 to the front side and the rear side. For example, there is a drive unit that transmits the drive of the motor in the moving direction of the shutter 541.

  5 and 6 show a state where the shutter 541 has moved to the front side. In a state where the shutter 541 is moved to the front side, the through hole 5413 matches the discharge port 19 to open the discharge port 19, and a portion on the rear side of the first plate-shaped member 5411 is retracted from above the suction port 18. The suction port 18 is opened. Furthermore, in the state where the shutter 541 has moved to the front side, the second plate-like member 5412 blocks between the back duct 171 and the bottom duct 172. Further, in a state where the shutter 541 has moved to the front side, the support shaft 5421 is positioned at the inclined portion 5422a of one end portion (front end portion) of the guide rail 5422.

  In the state shown in FIG. 5 and FIG. 6 described above, the air (internal atmosphere) inside the product storage containers 141, 142, and 143 is supplied to the rear duct 171 and the suction passage 18a by the internal fan 51 as shown in FIG. The first chamber 532, the evaporative heat exchanger 33, the second chamber 533, the discharge passage 19 a, and the bottom duct 172 circulate through a circulation path that returns to the inside of the product storage containers 141, 142, and 143. More specifically, the air inside the product storage containers 141, 142, and 143 evaporates on the way from the suction passage 18 a to the first chamber 532 and to the second chamber 533 by the action of the internal fan 51. Cooled by the heat exchanger 33. The cooled air moves to the product storage boxes 141, 142, and 143 through the discharge passage 19 a and the bottom duct 172. That is, the cooled air moves in such a manner that it passes through the product group stored in the product storage rack 16. When the cooled air moves in such a manner as to pass through the commodity group, heat exchange is performed between the cooled air and the commodity, and the commodity is cooled.

  When the shutter 541 is moved rearward from the state shown in FIGS. 5 and 6, the support shaft 5421 is lifted upward by the inclination of the inclined portion 5422 a at one end of the guide rail 5422. Accordingly, the closing surface 5414 of the shutter 541 having the support shaft 5421 separates in a state where it faces the upper surface (wall surface) 147a of the bottom plate 147 of the commodity storages 141, 142, 143. At the same time, the support shaft 5421 is moved rearward by the inclined portion 5422a. In this way, the shutter 541 moves rearward along the upper surface (wall surface) 147a as the closing surface 5414 is separated from the upper surface (wall surface) 147a of the bottom plate 147. Thereafter, as shown in FIG. 9, the support shaft 5421 moves to the separation portion 5422 b in the middle portion of the guide rail 5422. Thereby, the shutter 541 moves rearward along the upper surface (wall surface) 147a in a state where the closing surface 5414 is separated from the upper surface (wall surface) 147a of the bottom plate 147 of the commodity storages 141, 142, 143. Further, as the shutter 541 moves, the support shaft 5421 reaches the inclined portion 5422 a at the other end of the guide rail 5422. At this inclined portion 5422a, the support shaft 5421 falls downward. Therefore, as shown in FIGS. 10 and 11, the closing surface 5414 of the shutter 541 having the support shaft 5421 comes into contact with the upper surface (wall surface) 147 a of the bottom plate 147 of the product storage containers 141, 142, 143. At the same time, the support shaft 5421 reaches the inclined portion 5422a at the other end (rear end) of the guide rail 5422 and stops the movement of the shutter 541. In this way, the shutter 541 stops moving to the rear side as the closing surface 5414 comes into contact with the upper surface (wall surface) 147a.

  As shown in FIGS. 10 and 11, in the state where the shutter 541 has moved to the rear side, the front side portion of the first plate-like member 5411 covers and closes the discharge port 19, and the rear of the first plate-like member 5411. The side portion covers and closes the suction port 18. Furthermore, in a state where the shutter 541 has moved to the rear side, the second plate-like member 5412 opens the space between the back duct 171 and the bottom duct 172.

  In the state shown in FIG. 10 and FIG. 11 described above, for example, the air (internal atmosphere) inside the product containers 141, 142, and 143 is, as shown in FIG. 173, passes through the bottom duct 172, and circulates in a circulation path that circulates only inside the product storage containers 141, 142, 143. More specifically, the air inside the product storage containers 141, 142, and 143 is added by the internal heater 52 while circulating inside the product storage containers 141, 142, and 143 due to the action of the internal fan 51. Be warmed. That is, the heated air moves in a manner that passes through the product group stored in the product storage rack 16. When the air thus heated moves in a manner that passes through the product group, heat exchange is performed between the heated air and the product, and the product is heated.

  Further, the state shown in FIGS. 5 and 6 described above and the state shown in FIGS. 10 and 11 can be performed in each of the commodity storage boxes 141, 142, and 143. For example, when only the product storage container 141 is in the state shown in FIGS. 10 and 11 and the other product storage containers 142 and 143 are in the state shown in FIGS. 5 and 6, the product stored in the product storage container 141 is added. The product which is heated and stored in the other product storage boxes 142 and 143 is cooled.

  When the shutter 541 is moved to the front side from the state shown in FIGS. 10 and 11, the support shaft 5421 is lifted upward by the inclination of the inclined portion 5422 a at the other end of the guide rail 5422. Accordingly, the closing surface 5414 of the shutter 541 having the support shaft 5421 separates in a state where it faces the upper surface (wall surface) 147a of the bottom plate 147 of the commodity storages 141, 142, 143. At the same time, the support shaft 5421 is moved forward by the inclined portion 5422a. In this manner, the shutter 541 moves forward along the upper surface (wall surface) 147a as the closing surface 5414 is separated from the upper surface (wall surface) 147a of the bottom plate 147. Thereafter, as shown in FIG. 9, the support shaft 5421 moves to the separation portion 5422 b in the middle portion of the guide rail 5422. Thereby, the shutter 541 moves to the front side along the upper surface (wall surface) 147a in a state where the closing surface 5414 is separated from the upper surface (wall surface) 147a of the bottom plate 147 of the commodity storages 141, 142, 143. Further, as the shutter 541 moves, the support shaft 5421 reaches the inclined portion 5422 a at one end of the guide rail 5422. At this inclined portion 5422a, the support shaft 5421 falls downward. Therefore, as shown in FIGS. 5 and 6, the closing surface 5414 of the shutter 541 having the support shaft 5421 comes into contact with the upper surface (wall surface) 147 a of the bottom plate 147 of the commodity storage 141, 142, 143. At the same time, the support shaft 5421 reaches the inclined portion 5422a at one end portion (front end portion) of the guide rail 5422 and stops the movement of the shutter 541. As described above, the shutter 541 stops moving forward as the closing surface 5414 comes into contact with the upper surface (wall surface) 147a of the bottom plate 147.

  In the vending machine described above, the cooling fan 53 is cooled by driving the internal fan 51 with the suction port 18 of the suction passage 18a and the discharge port 19 of the discharge passage 19a being opened by the shutter 541 of the shutter mechanism 54. The inside atmosphere is circulated inside the product storage boxes 141, 142, and 143, while the inside air is blown in a state where the suction port 18 of the suction passage 18a and the discharge port 19 of the discharge passage 19a are closed by the shutter 541 of the shutter mechanism 54. By driving the fan 51, only the internal atmosphere of the product storage boxes 141, 142, 143 heated by the internal heater 52 is circulated.

  In this vending machine, the shutter mechanism (opening / closing device) 54 includes the suction port (opening) 18 and the discharge passage (in the suction passage (passage) 18a communicating with the inside of the product storages 141, 142, 143 as described above). A discharge port (opening) 19 of the passage 19a is formed on the upper surface (wall surface) 147a of the bottom plate 147 of the product storage 141, 142, 143, and is a closed surface that covers and closes the suction port 18 and the discharge port 19 It has a shutter (opening / closing member) 541 on which 5414 is formed. Then, a position that is separated from the upper surface (wall surface) 147a by a predetermined distance from the position covering the suction port 18 and the discharge port 19 with the closing surface 5414 facing the upper surface (wall surface) 147a of the bottom plate 147 by the moving means 542. The position where the suction port 18 and the discharge port 19 are covered from a position separated from the upper surface (wall surface) 147a by a predetermined distance with the closing surface 5414 facing the upper surface (wall surface) 147a while the shutter 541 is moved to Until the shutter 541 is moved. For this reason, when opening and closing the suction port 18 and the discharge port 19, the edge of the shutter 541 and the edge of the suction port 18 and the discharge port 19 do not collide. Further, since the closing surface 5414 faces the upper surface (wall surface) 147a of the bottom plate 147 in a state of being separated from the upper surface (wall surface) 147a by a predetermined distance, the inside of the product storage containers 141, 142, 143 The moving region of the shutter 541 can be suppressed. As a result, it is possible to prevent the movement area of the shutter 541 from occupying the areas inside the product storage containers 141, 142, and 143, and the edge of the shutter 541 and the suction opening 18 when the suction opening 18 and the discharge opening 19 are opened and closed. Further, breakage of the edge of the discharge port 19 can be prevented.

  In Embodiment 1 described above, the in-compartment heater 52 is provided in at least one of the product storage units 141, 142, and 143, and the product storage unit provided with the in-compartment heater 52 is used for both cooling and heating. A product storage box that does not have the internal heater 52 may be used exclusively for cooling. In this case, the shutter mechanism 54 may be disposed only in the commodity storage provided with the internal heater 52.

  By the way, in Embodiment 1 mentioned above, as shown in FIG. 13, the fitting protrusion which fits along the inner edge of the suction port 18 of the suction passage 18a and the discharge port 19 of the discharge passage 19a to the obstruction | occlusion surface 5414 of the shutter 541. 543 may be provided. The fitting protrusion 543 is fitted with the suction port 18 and the discharge port 19 to maintain the airtightness that closes the suction port 18 and the discharge port 19. This further prevents the back atmosphere from leaking together. When the fitting projection 543 is provided, the inclined portion 5422a is not provided at one end portion (front end portion) of the guide rail 5422 in the moving unit 542, and it is formed so as to continue from the separating portion 5422b. By changing the shape of the guide rail 5422 in this way, when the shutter 541 is moved so as to open the suction port 18 and the discharge port 19, the fitting protrusion 543 is separated from the upper surface (wall surface) 147 a of the bottom plate 147. This prevents the fitting protrusion 543 and the upper surface (wall surface) 147a from coming into contact with each other.

  Moreover, in Embodiment 1 mentioned above, as shown in FIG. 14, you may provide the airtight member 544 surrounding the circumference of the opening edge of the suction inlet 18 of the suction passage 18a, and the discharge outlet 19 of the discharge passage 19a. The airtight member 544 is preferably made of an elastic body having airtightness such as a rubber ring, and is attached around the opening edges of the suction port 18 and the discharge port 19 as shown in FIG. Alternatively, the airtight member 544 may be provided on the closing surface 5414 of the shutter 541 although not explicitly shown in the drawing. This airtight member 544 is pressed by a closed surface 5414 in contact with the upper surface (wall surface) 147a of the bottom plate 147, so that the airtightness of the closed state of the suction port 18 and the discharge port 19 is maintained. Further prevent the atmosphere and the heated back atmosphere from leaking together. When the airtight member 544 is provided, the support portion along the upper surface (wall surface) 147a is connected to the other end portion (rear end portion) of the guide rail 5422 in the moving unit 542 so as to be continuous with the tip of the inclined portion 5422a. 5422c is formed. Thus, by changing the shape of the guide rail 5422, the position of the shutter 541 in a state where the airtight member 544 is pressed can be maintained.

  Further, in the first embodiment described above, as shown in FIG. 15, a recess 545 as a pressing unit may be provided on the upper surface of the first plate-like member 5411 in the shutter 541 and the surface opposite to the closing surface 5414. . The concave portion 545 is formed by the airflow circulating in the product storage boxes 141, 142, and 143 in the state where the suction port 18 and the discharge port 19 are closed by the shutter 541, as shown by arrows in FIG. In addition, the blocking surface 5414 blocking the discharge port 19 generates a pressing force that is pressed toward the upper surface (wall surface) 147a of the bottom plate 147. As a result, the airtightness that closes the suction port 18 and the discharge port 19 is maintained, so that the situation where the cooling internal atmosphere and the heated back atmosphere leak from each other is further prevented.

  As a modification of the pressing means, as shown in FIG. 16, a convex portion 546 as a pressing means may be provided on the upper surface of the first plate-like member 5411 in the shutter 541 and on the surface opposite to the closing surface 5414. . The convex portion 546 has a suction port as shown by an arrow in FIG. 15 due to the airflow of air circulating inside the product storage containers 141, 142, and 143 when the suction port 18 and the discharge port 19 are closed by the shutter 541. 18 and the discharge port 19 have a sloped surface 546a that generates a pressing force that is pressed toward the upper surface (wall surface) 147a of the bottom plate 147. As a result, the airtightness that closes the suction port 18 and the discharge port 19 is maintained, so that the situation where the cooling internal atmosphere and the heated back atmosphere leak from each other is further prevented. In the state where the suction port 18 and the discharge port 19 are closed by the shutter 541, the pressing means is such that the closing surface 5414 is circulated through the inside of the commodity storages 141, 142, 143 and the upper surface (wall surface) 147a of the bottom plate 147. Any configuration may be used as long as it generates a pressing force that is pressed toward the surface, and is not limited to the concave portion 545 illustrated in FIG.

  Note that the fitting protrusion 543 shown in FIG. 13, the airtight member 544 shown in FIG. 14, and the concave portion 545 shown in FIG. 15 or the convex portion 546 shown in FIG. 16 may be provided together.

  In the first embodiment described above, the moving unit 542 configured by the support shaft 5421 and the guide rail 5422 has been described, but the present invention is not limited to this.

More specifically, a pair of left and right support shafts 5471 are provided coaxially on the front side of the first plate-like member 5411 and a pair of left and right sides are provided coaxially on the rear side of the first plate-like member 5411. The fixed shaft 5472 is fixed to the bottom plate 147 side, is paired corresponding to each support shaft 5471, and is provided in parallel with the support shaft 5471. The connecting member 5473 connects the support shaft 5471 and the fixed shaft 5472 to each other by supporting the end portions formed in the longitudinal shape on the support shaft 5471 and the fixed shaft 5472 forming a pair. In other words, the moving means 547 forms a parallel link by the support shaft 5471, the fixed shaft 5472, and the connecting member 5473.

  According to this moving means 547, in the same manner as the above-mentioned moving means 542, and with the closing surface 5414 facing the upper surface (wall surface) 147a of the bottom plate 147 by the moving means 547, the suction port (opening) 18 The shutter (opening / closing member) 541 is moved from the position covering the discharge port (opening) 19 to the position separated from the upper surface (wall surface) 147a by a predetermined distance, while the closing surface 5414 is moved to the upper surface (wall surface) of the bottom plate 147. The shutter 541 is moved from a position separated from the upper surface (wall surface) 147a by a predetermined distance from the position facing the upper surface (wall surface) 147a to a position covering the suction port 18 and the discharge port 19 in a state of facing the surface 147a. For this reason, when opening and closing the suction port 18 and the discharge port 19, the edge of the shutter 541 and the edge of the suction port 18 and the discharge port 19 do not collide. Furthermore, since the closing surface 5414 is opposed to the upper surface (wall surface) 147a with the closing surface 5414 facing the upper surface (wall surface) 147a, the shutter 541 inside the product storage containers 141, 142, 143 is separated. It is possible to suppress the movement area. As a result, it is possible to prevent the movement area of the shutter 541 from occupying the areas inside the product storage containers 141, 142, and 143, and the edge of the shutter 541 and the suction opening 18 when the suction opening 18 and the discharge opening 19 are opened and closed. Further, breakage of the edge of the discharge port 19 can be prevented.

  The link mechanism is not limited to the parallel link of the moving means 547, and the upper surface (wall surface) from the position covering the suction port 18 and the discharge port 19 with the closing surface 5414 facing the upper surface (wall surface) 147a of the bottom plate 147. ) The shutter (opening / closing member) 541 is moved until reaching a position that is separated from the upper surface (wall surface) 147a by a predetermined distance from the upper surface (wall surface) 147a. Any configuration may be used as long as the shutter 541 is moved from the separated position to a position covering the suction port 18 and the discharge port 19.
