Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice cooker equipped with a heating device for inductively heating canned beverages such as canned coffee that have been stored in a refrigerated or frozen state.

In the conventional system, heating was uniformly applied from the side of the can, which resulted in unstable convection of the contents, resulting in higher temperatures at the top of the contents, resulting in uneven beverage temperature.

Additionally, the can side surface joints are joined with a resin adhesive.
For so-called adhesive cans, since the resin adhesive is not electrically conductive, conventional uniform heating causes problems such as can burn because heating energy is concentrated at the bottom of the can when it is housed in an induction heating device. Part of the purpose of the present invention is to improve the drawbacks of the above-mentioned conventional examples and to carry out effective heated sales.

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 stores articles such as canned coffee and milk, and has a known storage chamber 2 and an article supply device 3 inside which supply the articles one by one.

Furthermore, a cooling device 4 is built in the storage chamber 2 to cool and store the articles. Reference numeral 5 denotes a door body that is opened when storing articles in the storage chamber 2, and has a push-pull switch (not shown) for operating the article supply device 3 and an article sales opening 6 formed on the front surface, and a coil inside. A mechanism (not shown) is housed inside the bag.

7 is a lower part of the door body 5, and an article discharge port 8 of the storage room 2 is provided.
An induction heating device is provided below the induction heating coil 9, which is formed into a cylindrical shape with a closed top surface and arranged in three layers 9a, 9b, and 9c in the vertical direction.

Inside the induction heating device 7, there is a working village 11 that moves up and down and has a support slope 10 formed at the upper end that is tilted toward one side.
It is configured so that it appears. The operating punch 11 is vertically controlled via a rotary plate 13 rotated by the drive of a motor 12 and a connecting village 14 connected to the rotary plate 13. 15 is below the article discharge port 8 and is located below the workpiece outlet 1.
1 is an article guiding punch provided in parallel with the supporting slope portion 10 of No. 1, and the other end thereof is connected to the connecting villages 14 and 14', and is operated by swinging in the vertical direction in conjunction with the operating punch 11 by the drive of the motor 12. The support plate portion 10 of the punch 11 moves laterally in a scene-like manner.

The induction heating device 7, the motor 12, and the rotary plate 1
3. The connecting punches 14, 14', the article guide hole 15, etc. are connected to the article discharge window 8' and article sales outlet 6, which correspond to the article outlet 8.
and a frame 16 formed with a corresponding article sales window 6'.
The frame body 16 is attached to the inner lower part of the door body 6.

Reference numeral 17 denotes an article holder provided near the article sales window 6' of the frame 16.

Each coil 9a, 9b, 9 constituting the above-mentioned concessional heating device 9
c is configured so that two high-frequency currents flow through an induction heating unit 21 placed at an appropriate position within the main body, and each output end 21a, 21b, 21c of this concessional heating unit 21 is connected to each coil. There is.

Further, delay devices 22, 22' for temporarily cutting off the current from the concession heating unit 21 are interposed between the uppermost coil 9a, the lowermost coil 9c, and the respective output ends 21a, 21c. Furthermore, the devices 22 and 22' are configured to have different cutoff times. Next, the operation of the above foundation will be explained.

First, 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 coffee) that does not require heating on the plurality of selection buttons, the article supply device 3 in the storage room 2 will be activated and a "chilled article will be delivered from the outlet 8". At this time, the induction punch 15 of the heating device 7 is in the state shown by the dotted chain line in Figure 3, so when the article drawn out from the discharge window 8' falls downward, it moves upward. The supporting slope part 10 and the guide plate 15 of the working punch 11 directly transfer the article to the article receiving table 17 and fall thereon.

As a result, the cooled articles can be taken out from the sales outlet 6. Next, when you want to heat a canned item made of magnetic material to obtain a warm item, if you push out the god anchor at that position,
The article supply machine 3 in the storage room 2 of the machine operates and one cooled article is led out from the discharge port 8 to the discharge window 8', but at the same time the motor 12 is driven and the rotary plate 13 is rotated as shown in FIG. While rotating in the direction of the arrow, the operating punch 11 is activated via the connecting punch 14.
is moved downward as shown in FIG. 3 and pushed down to the lowest part of the induction heating coil portion 9 to stop driving the motor 12.

Further, the article guiding punch 15 also moves in the direction of the arrow in FIG. 3 in conjunction with the connecting punch 14 and stops at a lower position. Therefore, the articles discharged to the discharge window 8' are guided to the article transfer area 15 and stored inside the transfer heating coil section 9 from the upper surface entrance.

At this time, when it is confirmed by a detection means such as a switch that the article is accommodated in the induction heating coil section 9, the induction heating unit 21 is energized, and the heating coil gb is turned on as shown in FIG.
The energization is started simultaneously with the start of energization of the induction heating unit 21. However, the induction heating coils 9a, 9c are energized with a time difference as shown in FIG. 5 by the delay rhombuses 22, 22'.

The reason for providing this energization time difference is that the uppermost coil 9a
utilizes the convection effect of canned beverages, and the long lower coil 9c assumes that the can is an adhesive can, and when the can is housed in the induction heating device 9, the adhesive can This is to eliminate problems such as can burn, which occur when heating energy is concentrated at the bottom of the can.

When a predetermined period of time has elapsed, the timer turns off the current to the conductive heating coil 9, and the motor 12 is driven again to push the working village 11 upward. In conjunction with this, the article transfer pestle 15 moves downward, and the heated canned beverage is transferred from the upper surface of the induction heating coil section 9 to the article receiving stand 17.
The canned beverage can be taken out as a warm heated canned beverage through the sales outlet 6. As described above, the present invention has a plurality of coils in the induction heating device, and is provided with a device that varies the energization time of each coil, which solves problems such as uniformity of canned beverage temperature and burning of adhesive parts. This solves the problem, enables effective heated sales, and improves the operating rate of the vending machine.

Moreover, it has various advantages, such as contributing to the power of honor by changing the time setting of the delay device.
