Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vending machine that quickly heats and sells canned coffee, milk, etc., and one of its objects is to improve heating efficiency.

Conventionally, vending machines that use microwave oscillator tubes, such as the one shown in Japanese Utility Model Publication No. 48-33356, have been widely known as vending machines that quickly heat stored items and release them into a vending outlet. Since both of these systems use microwave heating methods, they are unable to heat items housed in metal containers, such as canned coffee.

In particular, the present invention utilizes a concessional heating coil as a heating device in a vending machine suitable for canned goods such as steel materials.
It is designed to effectively and rationally heat the contents of beverages and the like stored in the can.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes a vending machine main body, which includes a storage chamber 2 in which goods such as canned coffee and milk are stored, and a known goods supply device 3 that supplies the goods one by one in response to a predetermined signal.
are provided for each.

Here, a cooling device (not shown) is provided in the storage room 2 to constantly keep the articles cool. Reference numeral 5 denotes a door body that is opened when storing articles in the storage room 2. On the front side of the door body 5, a push button switch (not shown) for operating the article supply device 3 and an article sales opening 6 are provided. A coin machine (not shown) is provided on the inner surface.

Reference numeral 7 denotes an article heating device provided at the lower part of the inner door 5' interposed between the door body 5 and the storage chamber 2, and located below the article outlet 8 of the storage chamber 2. The induction heating coil 9, which is wound into a coil in the same direction, is integrally molded with synthetic wood fingers to form a cylindrical shape with both upper and lower sides closed.

Reference numeral 10 denotes a support slope portion that moves up and down the center of the yield heating coil 9, and its upper end surface is formed to be inclined toward one side.

Here, the height of the heating device 7 is set lower than the height of the can, which is the article to be heated. Reference numeral 11 denotes a working punch, and this working village 11 includes a rotary plate 13 rotated by the drive of a motor 12 and a connecting punch 14 connected to the rotary plate 13.
, 14, the support plate section 10 is moved up and down.

15 is located below the discharge port 8 and the operating punch 11
The other end of the article guiding punch 15 is connected to the connecting village 14 and is moved vertically in conjunction with the working village 11 by the drive of a motor 12. It oscillates and works sideways with the support plate portion 10 of the operating punch 11 in a scene-like manner.

Here, the article heating device 7, motor 12, rotating plate 1
3. The connecting villages 14, 14, the article guidance village 15, etc. are a frame body 1 in which an article discharge window 8' corresponding to the article discharge port 8 and an article sales window 6' corresponding to the article/article sales opening 6 are respectively formed.
It is attached to 6. The frame body 16 is attached to the inner door 5'.
installed at the bottom of the 17 is the goods sales window 6'
This is an article holder provided on the frame 16 in close proximity to the article holder.

Next, the operation of the vending machine having the above configuration will be explained.

First, a predetermined coin is inserted into the coin slot of the vending machine main body 1 and the selection button is pressed.

Now, when you press the position of a cold article (canned 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 a small cooled article is discharged from the discharge port 8. It is led out to window 8'. Then, the heating device 7
Since the working village 11 and guiding village 15 are in the state shown by the chain lines in FIG. It moves directly in the direction of the pedestal 17 and falls. As a result, the cooled article can be taken out from the sales outlet 6.
Next, when you want to heat the article to obtain a warm article, press pusher 0 at that position, and the article supply device 3 in the storage room 2 operates as described above, and each cooled article 1 is delivered from the discharge port 8. It is led out to the discharge window 8'.

At the same time, the motor 12 is driven to rotate the rotating plate 13 in the direction of the arrow in FIG. The cylindrical induction heating coil 9 is pushed down to the lowest part to stop driving the motor 12. In conjunction with this, the article guiding pestle 15
It also moves in the opposite direction of the arrow in FIG. 3 in conjunction with the connecting punch 14 and stops above. Therefore, the articles drawn out from the discharge window 8' are guided by the article guiding hole 15 and stored inside the induction heating coil 9 through the upper closed portion thereof. At this time, when it is confirmed by a detection means such as a switch that the article has been accommodated in the induction heating coil 9, a timer (not shown) is activated to energize the induction heating coil 9 for a predetermined period of time. At this time, as shown in FIG. 4A, an eddy current is generated on the surface of the article (the can surface) by the magnetic field of the coil 9, heating the outer surface of the lower part of the article to a high temperature in an extremely short period of time, and the liquid contained inside the article. is heated by heat convection upward as shown by the arrow. As a result, the outer surface of the can is not heated excessively, and the liquid inside is efficiently heated. Here, if the induction heating coil 9 is installed horizontally as shown in Figure 4, eddy currents will occur on the can surface as described above and the outer surface of the can will be heated to an extremely high temperature. Since the entire surface of the can, including the top and bottom, is heated, an abnormally heated superheat temperature castle A is formed on the top surface of the can.

That is, the internal liquid heated on the bottom surface of the can convects upward and its temperature rises, but in addition to this increased temperature, it is further heated by the coil 9, so that the heated liquid temperature is increased by the heating by the coil 9. The temperature will be added to the temperature, which is dangerous as there is a risk of burns to the purchaser, and the heated liquid will convect on both the left and right sides of the can, forming an overheating temperature castle A. The convection efficiency is not so good compared to the one installed vertically as in the example. When the heating for a predetermined period of time is completed in this way, the timer disconnects the power to the induction heating coil 9, and the motor 12 is re-driven to push the working village 11 upward, and in conjunction with this, the article guiding punch is 15 is lowered, and the heated article is guided through the support slope 1 from the entrance part of the upper surface of the induction heating coil 9 toward the article receiving stand 17, and the warm heated article is obtained from the sales outlet 6.

In the above embodiment, the heating of the can is performed by time control, but similar effects can be expected by temperature control.

It is also possible to operate the support slope part 1 manually and to discharge the gas at a desired temperature. As is clear from the above embodiments, the vending machine of the present invention has a storage section provided in the vending machine main body near the article outlet.
an induction heating coil which is open on both upper and lower sides and has a cylindrical shape and whose height is set lower than the height of the object to be heated and which heats an object to be heated housed therein; and an induction heating coil located at the bottom of the induction heating coil. When the article is introduced from the article discharger into the induction heating coil, and when the article is located above the upper part of the induction heating coil, the article is moved up and down to guide the article to the article receiving stand of the article sales outlet. Since induction heating is performed with the article to be heated standing upright, if the article to be heated is stored in a can container, the entire can can be heated effectively and rationally. The heating time is extremely short. Furthermore, by configuring the heating device with a heating coil and setting the height of the heating coil to be lower than the height of the article to be heated, it is possible to uniformly heat the entire object due to the convection properties of the heat. No uneven heating occurs. In addition, since the articles are introduced and guided to the article pedestal from the top of the induction heating coil that extends in the vertical direction by the vertical movement of the ejection device, the articles are more securely delivered to the article than the induction heating coil that rotates. can be discharged. Moreover, since there is no rotating motion of the induction heating coil, there is no drawback that the electrical wiring may be twisted and broken.
