2. Description of the Related Art First, FIG. 3 shows the structure of a can product vending machine to which the present invention is applied. In the figure, 1 is a product storage cabinet that serves as a heat-insulating housing in which a product rack (serpentine type product rack) 2, a cooler 3, a fan inside the product 4, a product unloading shooter 5 and the like are housed in the storage, and 6 is a cabinet 1. Front outer door, 7 is a product outlet provided on the outer door 6,
Reference numeral 8 denotes a heat-insulating inner door which is disposed between the cabinet 1 and the front outer door 6 so as to cover the front surface of the product storage compartment. The heat-insulating inner door 8 has the above-described product carry-out shooter 6 at the lower end of the door plate. A product payout port 8a having a flapper 9 is opened so as to be linked to the product takeout port 7. Reference numeral 10 is a water guide gutter attached to the cabinet 1 so as to receive the condensed water that has condensed on the surface of the heat insulating inner door 8 and flows down to the evaporation tray 11 installed in the machine.

With such a configuration, the inside of the cabinet 1 is cooled by the cooler 3, and the products 12 stored in the product rack 2 are kept at a temperature suitable for sale. Then, the product 12 dropped from the product rack 2 by the product selling operation is transferred to the shooter 5
Slides down, pushes open the flapper 9 provided at the product outlet 8a of the heat insulating inner door 8, and rolls down into the product outlet 7.

Next, FIG. 4 shows a detailed conventional structure around a product outlet surrounded by a chain line in FIG. In FIG.
A frame-shaped outlet frame 14 made of a resin molded product is fitted into the product outlet 8a opened in the heat insulating inner door 8 from the front side of the door plate, and a flapper 9 can be opened and closed in the frame 14. Is installed in the bottom of the door plate, and further, the water guide girder 15 for relay that guides the condensed water dripping from the front wall surface of the heat insulating inner door 8 to the water guide gutter 10 along the outlet frame 14.
Is installed. In addition, 16 is a gasket provided on the rear surface side peripheral edge of the heat insulating inner door 8. Further, a product takeout door 7a is provided on the front surface of the product takeout opening 7, and a product receiving box 7b for accommodating the product 12 rolled out from the product payout opening 8a of the heat insulating inner door 8 is incorporated inside the outer door 6. ing.

[0005]

However, the above-mentioned conventional structure has the following problems. In other words, recently, the vending machine installed at the location has become a social problem because it is a social problem, and the vending machine is becoming thinner, and accordingly the front outer door 6 of the cabinet 1 is made thinner. It is designed and manufactured to have a structure.

However, when the outer door 6 is constructed to have a thin structure, the depth dimension of the product receiving box 7b of the product take-out port 7 incorporated in the outer door 6 is inevitably in the conventional structure shown in FIG. Will be reduced. For this reason, there arises a problem that it is not possible to secure a sufficient space between the heat-insulating inner door 8 and the product outlet 7 to receive the product 12 carried out from the inside, which makes the outer door 6 thin. You are constrained.

The present invention has been made in view of the above points, and by improving the structure of the product dispensing outlet opening in the heat-insulating inner door of the cabinet, the heat-insulating inner door and the product outlet of the front outer door can be connected. It is an object of the present invention to provide a heat-insulating inner door that secures a sufficient product take-out space in between and enables the vending machine to be made thinner.

[0008]

In order to achieve the above-mentioned object, according to the structure of the present invention, with respect to the product dispensing outlet opened at the lower part of the heat insulating inner door, the front edge opening end on the bottom side is the heat insulating inner door. A recess is formed at the lower end of the front side of the door plate, which is a recess for the product that has passed through the payout opening, so as to be recessed and opened one step further than the front surface of the door plate.

Regarding the frame-shaped payout outlet frame attached to the product payout outlet of the heat-insulating inner door, the bottom frame portion is matched with the recessed cross-sectional shape of the heat-insulating inner door, and is more than the peripheral edge portion of the remaining three sides. It shall be formed by retracting one step further. Further, with respect to the outlet frame, the lower edge thereof extends below the heat-insulating inner door to form a water piece of dew condensation water, and the water piece is attached to the lower end of the heat-insulating inner door toward the tip of the water piece. It can be configured by providing a relay water conduit for guiding the condensed water dropped from the inside to the evaporation tray installed in the machine.

[0010]

According to the above construction, the lower edge opening end of the product outlet that opens in the heat-insulating inner door is formed inside the door plate, and is recessed one step further than the front surface of the door plate. Is formed with a recess that serves as a passageway for products. Therefore, a product that passes through the product discharge chute on the inside of the warehouse and passes through the product outlet of the heat-insulating inner door should fall from the front side of the front plate of the heat-insulating inner door into the product receiving box of the product outlet through the recess. Thus, the product take-out space between the product take-out opening provided in the outer door and the product is expanded by the depth of the recess. As a result, the outer door can be made thin and the vending machine as a whole can be made thinner.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings of the embodiments, the same members corresponding to those in FIG. 4 are designated by the same reference numerals. As shown in the sectional view of FIG. 2, the commodity outlet 8a opened at the lower end of the heat-insulating inner door 8 in FIG. 1 and FIG. 2 has the front edge open end on the bottom side recessed by a dimension A from the front surface of the door plate. Is formed in a vertical position, and the door plate portion ahead of that is locally cut out to form a recess 8b serving as a product drop passage. In addition, the outlet frame 14 fitted and mounted in the product outlet 8 has a bottom frame portion 14a recessed behind the flange end faces of the other three side peripheral frame portions in accordance with the cross-sectional shape of the heat insulating inner door 8 described above. Further, a water section 14b is formed at the front end portion extending from the lower end of the bottom frame portion 14a so as to wrap around and hang down so as to project to the rear lower surface side of the heat insulating inner door 8. Further, as shown in FIG. 1, on the lower end surface of the heat insulating inner door 8 toward the tip of the water piece 14b, the dew condensation water dripping from the water piece 14b along the outlet frame 14 is received and guided to the water guiding trough 10. A water conduit 15 for relay is attached. The water conduit 15 is mounted in the direction opposite to that of the conventional structure shown in FIG.

With such a structure, the product is unloaded from the product rack in the warehouse, and then the product discharge port 8a of the heat insulating inner door 8 is passed through the shooter 5.
The product 12 passing through is dropped downward from the front edge of the bottom frame portion of the outlet frame 14 through the recess 8b, and is dropped into the product receiving box 7b of the product outlet 7 provided inside the outer door 6. . That is, as compared with FIG. 4, the heat insulating inner door is dropped from the front side in the middle of the cross section into the product receiving box 7b.
The product take-out space between the product take-out port 7 and the product is increased by the depth dimension A of the recess 8b.

Further, the water droplets that have condensed on the surface of the heat insulating inner door 8 while keeping the inside of the refrigerator cold are transmitted along the carry-out port frame 14 and dropped from the water section 14b at the tip thereof to the water guide receiver 15 from which another water guide trough is provided. It is guided to the evaporation dish 11 via 10 and is evaporated here. In this case, since the water piece 14b and the water guiding trough 15 are provided behind the above-mentioned recess 8b, there is no risk of interfering with the product 12 falling from the product dispensing outlet 8a.

[0014]

As described above, according to the structure of the present invention, the heat insulating inner door and the front outer door are formed by forming the recess serving as the product drop passage in the product outlet opening of the heat insulating inner door. The product take-out space between the product take-out port and the product take-out port can be expanded, and by expanding the product take-out space, the front outer door can be made thin to contribute to the promotion of thinner vending machines.
