DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for a vending machine.

[0002]

2. Description of the Related Art Conventionally, in a vending machine which sells products by cooling or heating the products, a storage room is generally formed with a heat insulating wall in a main body, has a front surface opened, and keeps the stored products warm or cool. Is provided.

[0003] The opening of the storage room is usually covered with an inner door. In order to maintain the airtightness of the storage room with a packing generally provided on the inner door and to effectively keep the storage room warm or cool, It is also important to enhance the heat insulation of the inner door, but it is necessary to make the inner door thin to accommodate the inner door in a limited space in the main body.

[0004] A drain is provided over the entire width of the bottom surface of the inner door in order to guide the condensed water sweated due to the temperature difference between the inside and the outside of the warehouse to the drain port (Japanese Patent Laid-Open No. 8-297775).
Reference).

Hereinafter, a conventional vending machine will be described with reference to the drawings.

FIG. 4 is a side sectional view of a conventional vending machine. FIG. 5 is a sectional side view of a main part of an inner door and a drainage device of a conventional vending machine, and a left side of the figure is a front side.

In FIGS. 4 and 5, reference numeral 1 denotes a main body having an inner box 2 therein. A carry-out shelf 3 is mounted in the inner box 2. An unloading guide plate 4 is provided above the bottom plate of the inner box 2.

Reference numeral 5 denotes an inner door provided on the front surface of the main body 1. An outer peripheral surface of the inner door 5 has a box 6 having an opening facing the opening of the carry-out shelf 3, and an opening of the box 6. The cover 7 on a flat plate to cover, the cover 7, and the cover 7 are joined to the box 6 and have an end face facing the opening surface of the carry-out shelf 3. It is composed of a packing 9 having a groove 8 fitted therein.

The inner door 5 is filled with a foaming material 10 which is made by injecting and foaming a stock solution, and the inner door 5 is provided with a square hole 11. An opening and closing plate 12 having a hinge mechanism is attached to the square hole 11. A main door 13 is provided with a product take-out section 14 having an opening formed on the front surface.

On the inner surface of the main door 13, a side plate 15 and a bottom plate 16 are provided.
, And a product receiving portion 18 composed of a rear wall 17. A drain 19 is provided on the bottom surface of the inner door 5 over the entire width of the inner door, and is fixed by screws 20.

The operation of the vending machine configured as described above will be described below.

In the above configuration, when the inner door 5 is closed, the gap between the front end face of the heat insulating wall forming the inner box 2 and the inner door 5 is closed by the packing 9 to make the inside of the inner box 2 airtight. While holding, the foam material 10 prevents heat from flowing into and out of the inner box 2.

Thus, the goods stored in the inner box 2 are efficiently kept warm in the inner box 2 and stored in a warm, refrigerated or frozen state.

Condensed water that sweats on the surface of the box 6 and the opening / closing plate 12 due to the temperature difference between the inside and outside of the inner box 2 is collected by the drain 19 and guided to the drain port.

In the vending machine selling operation, when money is inserted from a slot (not shown) and a product is selected by a push button (not shown), the selected product is stored in accordance with a sales command signal. From the carry-out shelf 3, falls onto the carry-out guide plate 4, pushes the opening / closing plate 12 open, passes through the square hole 11 of the inner door 5, and enters the product receiving portion 18. The customer puts his hand out of the product take-out unit 14 and takes out the product.

[0016]

The drainage structure of the inner door of such a vending machine has a structure in which the drain 19 is fixed to the inner door 5, so that the dew condensation sweating on the inner door 5 is exposed to the inside of the vending machine. It is required not to cause adverse effects on electrical components and the like.

However, in the conventional structure of the inner door 5 and the drain 19, in order to reduce the weight of the inner door 5, the thickness of the material of the box 6 and the cover 7 constituting the inner door 5 is 1 mm or less. Is commonly used. Therefore, when the drain 19 is fixed to the inner door 5 with the screw 20, the probability of forming a screw stupid is very high, and the number of working steps is large.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a vending machine in which a drain can be easily attached to a lower end of an inner door.
