By bending the plate-like member 85 as appropriate, a front-side sheet metal body 82 as shown in FIG. 15 is created.

  That is, the front-side sheet metal body 82 has a groove 88 formed in a portion 851 where the notch 82a of the plate-like member 85 is formed so that the removal member 86 is connected to the plate-like member 85 by the micro joint 87, and is subjected to bending. After the removal, the removal member 86 is removed to form a notch 82a.

  The product carry-out frame 83 is for defining the product carry-out port 61 of the lower inner door 60b, and is configured by a resin material in a rectangular frame shape. As shown in FIG. 18, each commodity outlet frame 83 is provided with a back flange 83 b and a front flange 83 c on a frame body 83 a formed by using an upper frame 83 a 1, a pair of side frames 83 a 2, and a lower frame 83 a 3 as four-round frames. . The back flange 83b and the front flange 83c are portions extending outward from the peripheral edge of the opening of the frame main body 83a. In addition, the product carry-out frame 83 is gradually inclined backward from the middle level to the lower part so that the front surface of the both side frames 83a2 of the frame main body 83a fits the lower end portion of the front side sheet metal main body 82. It is an inclined surface. Furthermore, a locking hook portion 831 that protrudes rearward is formed on the front flange 83c constituting the inclined surface.

  Outside the peripheral edge of the frame main body 83a in the product carry-out frame 83, a protrusion 832 having a triangular cross-sectional shape is formed over the entire peripheral area excluding the lower frame 83a3. Further, as shown in FIG. 19, in the product carry-out frame 83, a hinge structure portion 833 serving as an opening / closing movement axis of the product carry-out door 62 is formed on the inner surface of both side frames 83a2 of the frame body 83a. A punching hole 834 for forming the hinge structure portion 833 is formed in each side frame 83a2.

  The product carry-out frame 83 having the above-described configuration is formed by sliding the front-side sheet metal body 82 on the door body 81 and then sliding it from the lower end surface of the door body 81 to the unloading opening 81a as shown in FIG. The door body 81 is attached. In this case, the product outlet frame 83 is attached to the door main body 81 with the rear flange 83b superimposed on the rear surface of the door main body 81 and the front flange 83c superimposed on the front surface of the front side sheet metal main body 82. That is, the product carry-out frame 83 is mounted such that the door body 81 and the front-side sheet metal body 82 are sandwiched between the rear flange 83b and the front flange 83c of the product carry-out frame 83. The product outlet frame 83 attached to the door main body 81 is fixed to a desired position by screwing it to the front side sheet metal main body 82 via the front flange 83c, for example. At this time, as shown in FIG. 21, the hook hook portion 831 formed in the commodity outlet frame 83 is made to enter the locking hole 82 b of the front side sheet metal body 82 and hooked on the front side sheet metal body 82. The inward fall of the carry-out outlet frame 83 is prevented.

  By attaching the product outlet frame 83 to the door main body 81 in this way, the protrusion 832 formed on the frame main body 83a bites into the edge of the unloading opening 81a of the door main body 81 as shown in FIG. become.

  Then, as shown in FIG. 23, the guide member 84, which is a long plate member whose longitudinal direction is the width direction of the door main body 81, is below the door main body 81 with respect to the door main body 81 to which the commodity outlet frame 83 is attached. The lower inner door 60b is formed by being attached by screws or the like so as to cover the end face and the lower frame 83a3 of the commodity outlet frame 83.

  As described above, the guide member 84 is a long plate material in which the width direction of the door body 81 is the longitudinal direction, and is made of metal. The guide member 84 has a double-curved cross-sectional shape, and has a guide base 841 and a guide end 842 as shown in FIG. The guide base 841 covers the lower surface of the lower end portion of the door main body 81 and the lower frame 83a3 of the product outlet frame 83, and covers the lower surface of the door main body 81 and the lower surface of the lower frame 83a3 of the product outlet frame 83 in the middle. And is attached to the door body 81 with screws. The guide end portion 842 is a portion that is bent downward from the front edge portion of the guide base portion 841 and extends downward so as to be connected to the inclined surface of the front-side sheet metal body 82 to form the same plane. That is, the guide end portion 842 is inclined so as to face the back side of the door body 81 as it goes downward.

  Such a guide member 84 causes the condensed water generated on the outer surface (particularly the front surface) of the lower inner door 60b to drip through the front surface of the guide end 842, and as shown in FIG. It guides to the eaves member 17 arrange | positioned. Here, the eaves member 17 is attached to the front end surface of the bottom wall 13 together with the gasket member 18 provided from the viewpoint of ensuring the airtightness of the commodity storage 23. The gutter member 17 is for guiding the condensed water guided from the guide member 84 to a predetermined evaporating dish (not shown).

  The guide member 84 is provided with a spacer member 90 at the guide end 842. The spacer member 90 is made of, for example, a resin material, and a plurality of spacer members 90 are arranged at predetermined intervals along the longitudinal direction of the guide member 84 so as to protrude toward the front surface side of the guide end portion 842.

  In such a spacer member 90, the inner door 60 (the upper inner door 60 a and the lower inner door 60 b) closes the front opening of the entire commodity storage 23 (the commodity accommodating chamber 20), and the outer door 50 is the outer box 10. When the front opening is closed, a gap S is formed between the guide end portion 842 and the end portion of the product takeout portion 52. More specifically, when the inner door 60 closes the front opening of the entire commodity storage 23, the gasket member 18 provided in the outer box 10 is pressed. The lower end portion of the inner door 60 (particularly the lower inner door 60b) is bent forward by the reaction force (the side away from the product storage case 23). Thus, even if the lower end portion of the inner door 60 is bent, the spacer member 90 abuts against the end portion of the product take-out portion 52 of the outer door 50, so that the space between the guide member 84 and the product take-out portion 52 is reduced. A gap will be formed.

  In the vending machine having the above-described configuration, the heat insulating board 21 disposed at the installation site of the bottom wall 13 of the outer box 10 includes the first heat insulating plate material 211 disposed in a manner covering the installation site. The first heat insulating plate material 211 has a heat resistance higher than that of the first heat insulating plate material 211, and the second heat insulating plate material 212 placed on the first heat insulating plate material 211 in a form fitted in the installation recess 2113. The second heat insulating plate material 212 may be installed only at the installation location of the electric heater 25b, and only the first heat insulating plate material 211 may be installed throughout the installation site of the bottom wall 13. In addition, the first through hole portion 2111, the second through hole portion 2112, and the like may be formed only in the first heat insulating plate material 211.

  Therefore, by reducing the material cost of the second heat insulating plate material 212, the material cost of the entire heat insulating board 21 can be reduced, and the second heat insulating plate material 212 has, for example, a rectangular shape suitable for the installation recess 2113. Since only the first heat insulating plate material 211 is formed and the first through hole portion 2111 and the second through hole portion 2112 are formed, the processing cost can be reduced. Therefore, cost reduction can be achieved. Further, only the first heat insulating plate 211 may be disposed at the installation site of the bottom wall 13, and the work efficiency in the installation work can be improved as compared with the conventional case where the double heat insulating structure is disposed. it can.

  In the vending machine, when the rack support frame 30 is placed on the rear frame member 29 via the placement portion 31d, the heat insulating block member 35 is elastically deformed so that a part of the rack support frame 30 is rear frame. While entering the inside of the slit 29d of the material 29 and covering the exposed portion of the rear frame material 29 to the commodity storage 23, it is possible to reduce heat leak from the rear frame material 29 which is an attachment member. . In addition, since the heat insulating block member 35 is held by the rack support frame 30, it is not necessary to install the heat insulating block member 35 alone, and can be installed in accordance with the mounting of the rack support frame 30, so that the heat insulating work can be performed. It can be easy.

  Therefore, the heat insulation work can be simplified while reducing the heat leak of the rear frame member 29.

  Further, in the vending machine, the evaporating sheet body 73 erected on the lower reinforcing metal member 72 of the upper inner door 60a absorbs the condensed water generated on the front surface by capillary action. In this way, it is easier to evaporate the condensed water than when only the condensed water is stored in the reinforcing metal member, and when the upper inner door 60 is opened and closed, the condensed water drops on the floor or the like due to centrifugal force. Can be suppressed. Therefore, the condensed water produced on the outer surface of the upper inner door 60a can be positively evaporated.

  In the vending machine, the front-side sheet metal body 82 constituting the lower inner door 60 b is connected to the plate-like member 85 by a microjoint 87 at a portion where the notch 82 a of the plate-like member 85 is cut. Since the groove 88 is formed and the notch 82a is formed by removing the removing member 86 after the bending process is performed, the bending process can be favorably performed using a general-purpose mold mechanism. it can. Therefore, the manufacturing cost can be reduced without requiring a dedicated mold mechanism or the like as in the prior art.

  Moreover, in the vending machine, the commodity carry-out frame 83 constituting the lower inner door 60b bites into the edge of the carry-out opening 81a on the surface of the door body 81 that contacts the edge of the carry-out opening 81a. Since the formed protruding portion 832 is provided, the airtightness between the door main body 81 and the merchandise carry-out frame 83 can be ensured satisfactorily.

  In addition, since the mold release hole 834 for forming the hinge structure portion 833 of the product exit door 62 is formed in the side frame 83a2 of the product exit frame 83, the inside and outside of the lower inner door 60b is formed through the mold release hole 834. Air does not flow in the direction, and airtightness can be improved.

  Further, since the product carry-out frame 83 prevents the inward fall by engaging the locking hook portion 831 into the locking hole 82b of the front side sheet metal body 82 and hooking it on the front side sheet metal body 82. There is no risk of stress concentration in the locking hook portion 831 and the like, the strength against the sales load can be sufficient, and the locking hook portion 831 only enters the locking hole 82b. Attachment and removal of the frame 83 can be performed easily.

  Further, in the vending machine, the spacer member 90 includes the inner door 60 (the upper inner door 60a and the lower inner door 60b) that closes the front opening of the entire product storage 23 (product storage chamber 20) and the outer door 60 (the product storage chamber 20). When the door 50 closes the front opening of the outer box 10, a gap S is formed between the end and the guide end 842 by contacting the end of the product take-out portion 52. Condensed water generated on the outer surface drops on the outer surface of the guide end 842 of the guide member 84 and is guided to the gutter member 17. That is, it is possible to prevent the condensed water generated on the outer surface of the inner door 60 from entering the product take-out portion 52 of the outer door 50. Therefore, the dew condensation water generated on the outer wall surface of the inner door 60 can be guided to the gutter member 17 without entering the product take-out portion 52.

  In addition, since the spacer member 90 abuts against the end portion of the product take-out portion 52, the amount of bending of the inner door 60 can be restricted, and the product passing dimension can be sufficiently secured. Further, since the inner door 60 and the gasket member 18 can be sufficiently adhered to each other, the airtightness between the product containers 23 can be improved.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the embodiment described above, the spacer member 90 for forming the gap S between the guide member 84 and the product take-out portion 52 is disposed in the guide member 84. However, in the present invention, the product take-out portion It may be arranged in contact with the constituent members of the inner door. This also prevents the condensed water generated on the outer surface of the inner door from entering the product takeout portion.

  As described above, the vending machine according to the present invention is useful for selling products such as canned drinks and plastic bottled drinks.
