Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vending machine equipped with an induction heating device that can quickly heat and sell items such as canned coffee and milk.

Conventionally, many heating devices for this type of vending machine have been proposed in which the article guided into the heating device is taken out to the outside by a push-up rod or the like after heating is completed, but this take-out method has not been proposed. In addition to the push-up rod, complicated devices such as a drive motor and a connecting rod for connecting the motor and the push-up rod are required.

In the present invention, after heating the article housed in the heating device,
The product is guided to the sales outlet by its own weight.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a vending machine main body, which is provided with a storage chamber 2 for storing articles such as canned coffee and milk, and an article discharging device 3 for discharging the articles one by one.

Furthermore, a cooling device 4 is installed in the storage room 2 to cool and store the articles.

5 is a door body that opens when storing articles in the refrigerator compartment 2;
A push button switch for operating the article discharging device 3 and an article sales outlet 6 are formed on the front surface of the door body 5, and a coin mechanism is housed inside.

Reference numeral 7 denotes an article heating device installed below the product discharge port 8 of the inner door 5' interposed between the door body 5 and the storage room 2, in which an induction heating coil 9 for heating an iron plate by eddy current is connected to the upper and lower surfaces. It is constructed by integrally molding an open cylindrical shape with an insulating material 10 such as epoxy resin.

A cylindrical body 11 with a bottom is provided outside the heating device 7 at a predetermined interval to cover it.

This cylindrical body 11 is mounted concentrically with the mounting shaft 12 of the heating device 7, and has a portion 13 of its upper surface opened that faces the upper surface opening of the heating coil 9, and the central axis of this cylindrical body 11 is A motor 15 is connected to the heating device 7 via a belt 14, and rotates once around the mounting shaft 12 of the heating device 7.

That is, when it is confirmed that the article is stored in the heating device 7, a timer (not shown) is activated to supply electricity to the induction heating coil 9 of the heating device 7 to heat the article for a predetermined period of time. The motor 15 is driven to rotate the cylindrical body 11 once, and the articles in the heating device 7 are discharged and dropped downward through the opening 13 of the cylindrical body 11.

Reference numeral 16 denotes an operating rod that distributes the articles discharged from the article discharge port 8 in the direction of the opening 13 of the cylinder body 11 or in the direction of the direct sales outlet 6, and is operated as appropriate by operating the selection switch as indicated by the arrow in FIG. It slides left and right like this.

Next, the operation of the vending machine constructed as described above will be explained.

A predetermined coin is inserted into the coin slot of the vending machine main body 1 and the selection button switch is pressed.

Now, if you press the button switch for a cold item that does not require heating, such as a can of coffee, among the plurality of selection button switches, the item discharge device 3 in the storage chamber 2 will be activated and one cooled item will be removed. , are discharged from the article discharge port 8.

At this time, the operating rod 16' is at the dotted line position in FIG.
7 will be dropped.

Next, when the selection button switch for the position of the heated warm article is pressed, the article discharge device 3 is operated in the same manner as described above, and the article is discharged from the article discharge port 8, and at the same time, the operation rod 1
6 is moved to the solid line position in FIG.

When it is confirmed that the article is stored in the heating device 7, a timer is activated, and the induction heating coil 9 of the heating device 7 is energized for a predetermined period of time (for example, 20 seconds) to heat the article.

Thereafter, when the predetermined time described above has elapsed, the motor 15 is activated to rotate the cylindrical body 13 in the direction of the arrow in FIG. It falls onto platform 11.

Thereafter, when the cylinder 13 rotates once to the desired state, the operation of the timer is stopped and the operation of the motor 15 is also stopped, thereby completing the sales cycle.

As described above, the present invention stores articles inside a vending machine main body and is provided with an article discharging device for discharging the articles one by one to the outside. A cylindrical induction heating device with openings on both upper and lower sides that heats the article is disposed between the article ejecting device and the article take-out port and forms an outlet, and is arranged at a predetermined interval on the outside of the heating device. Since the product is rotatably equipped with a bottomed cylindrical body that accommodates the product in the high-frequency induction heating device when the top surface is open, and allows the product to fall into the outlet when the bottom surface is open, the product is not attached to the heating device. After heating the item using
Items can be delivered to the sales outlet simply by rotating the cylinder, and there is no need for complicated devices such as push-up rods or connecting rods as in the past, and the item can be ejected with a relatively simple device. In addition, if the cylindrical body rotates once, that is, after the article has surely fallen from the heating device, the next article will not be stored in the heating device even if it is accidentally ejected. This is preferable from the viewpoint of safety of the heating device.

Furthermore, by forming the cylinder body from a ferromagnetic material with high resistivity such as ferrite, the cylinder body itself absorbs the magnetic lines of force generated by the induction heating coil, and the magnetic force lines are absorbed by the outside inside the vending machine main body. There is no risk of magnetic field lines leaking into the metal parts of the device, causing them to heat up or cause radio interference.
