This frame 16 is attached to the lower part of the inner door 7'f). Reference numeral 17 denotes an article holder provided on the frame 16 in proximity to the article sales window 6'.

Furthermore, the operation of the above-mentioned configuration will be explained.

A predetermined coin is inserted into the coin slot of the vending machine main body 1 and a selection button is pressed. Now, when you press the position of a cold article (canned D coffee) that does not require heating on the plurality of selection buttons, the article supply device 3 in the storage room 2 is activated and one cooled article is delivered to the article discharge port. 8 to an article discharge window 8'.

The operating rod 11 and the guiding rod 15 of the heating device 7 are in the state shown by the chain lines in FIG. As a result, the cooled articles can be taken out from the article sales opening 6 because they roll and fall directly in the direction of the article holder 17 . Next, when you want to obtain a heated and warm article, press the button at that position, and the article supply device 3 in the storage room 2 will operate in the same way as described above, and one cooled article will be discharged from the article discharge port 8. At the same time, the motor 12 is driven to rotate the rotary plate 13 in the direction of the arrow in FIG. Cylindrical induction heating coil 9 installed vertically
and push down the plates 18, 18 to the bottom of the motor 12.
Stop driving. Furthermore, the article guiding rod 15 also moves in the opposite direction of the arrow in FIG. 3 in conjunction with the connecting rod 14 and stops above.

Therefore, the articles taken out from the article ejection window 8' are as follows:
The article is guided by the article guide rod 15 and housed inside the plate materials 18 through the upper openings thereof. At this time, according to the embodiment shown in FIG. 4, when the article is housed in the plates 18, 18, the elastic springs 19, 19 are expanded so that the plates 18, 18 come into close contact with the outer peripheral surface of the container of the article.

Further, in the embodiment shown in FIG. 5, when an article is housed in the plates 18, 18, the electromagnetic coils 21, 21 are activated, and the actuating rods 20, 20 move in the direction of the arrow M to move the article into the plates 18, 1.
Clamp at 8.

When it is confirmed that the articles have been accommodated in the plates 18, 18, a timer (not shown) is activated and when the articles pass through the induction heating coil 9 for a predetermined period of time, an eddy current is generated in the plates 18, 18, and the plates themselves The plate material 18,
Direct heat conduction between 18 and the Al can allows the article to be heated quickly.

In addition, if the container of the article is made of a ferromagnetic material such as a steel plate other than Al, eddy current is generated in the container itself in addition to heat conduction with the plates 18, 18, and the container itself is heated quickly. It is.

In this way, when the induction heating coil 9 is de-energized and the heating action is completed, the timer drives the motor 12 again to push the operating rod 11 upward and move the article guiding rod 15 downward.
c is lowered, and the heated article is guided toward the article holder 17 through the upper surface openings of the plates 18, 18, and taken out from the article sales opening 6 as a warm heated article.

In the embodiment shown in FIG. 5, the electromagnetic coils 21, 21 are deenergized and the plates 18, 18
Release the close contact between the product and the product.

As described above, the present invention includes a cylindrical induction heating coil near the article discharge port of the main body storage section, and a reinforced tube that is installed inside the inner surface of the heating coil and is divided into at least two pieces and formed into a cylindrical shape. A heating device is provided that includes a plate made of a magnetic material and a telescoping device that expands and contracts the inner diameter of the plate, and the telescoping device is actuated to separate the product and the plate at the same time as the article is accommodated in the plate of the heating device. Since the article is placed in close contact with the plate material and discharged to the outside after the induction heating coil is energized for a predetermined period of time, the article is securely brought into close contact with the plate material inside the induction heating coil and receives heat conduction. Therefore, irrespective of the ferromagnetic material of the container, it is rapidly heated by heat transfer from the plate.

Therefore, unlike in the past, there is no particular restriction on the type of container for articles, and by simply providing a general-purpose vending machine with the above-mentioned heating device, articles can be quickly heated and delivered to a sales outlet.
