Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a vending machine with an induction heating device for supplying a hot beverage by induction heating.

2. Description of the Related Art A conventional vending machine with an induction heating device is, for example, Japanese Patent Publication No.
As shown in 9-39797, FIG.
The structure was as shown in Fig. 7.

An example of the above-described conventional vending machine with an induction heating device will be described below with reference to the drawings. In the figure,
Reference numeral 1 is a main body of a vending machine, in which a cooling storage chamber 3 surrounded by a heat insulating wall 2 is formed. Reference numeral 4 denotes a door provided on the front surface of the main body 1, on the front surface of which are provided selection switches 5, 5, ... And an article take-out port 6 and the like, and on the back surface thereof is provided a heat insulating wall 7. The heat insulation wall 7 closes the front opening of the cooling storage chamber 3, but the cooling storage chamber 3 is located below.
An article outlet 8 for sale is formed which connects the article outlet 6 and the article outlet 6. The discharge port 8 is always closed by an opening / closing lid 9. Therefore, the cooling storage chamber 3 is provided with a cooling device and a delivery mechanism (not shown) for delivering one article in response to a sales instruction. Reference numeral 10 is an inclined guide path for guiding the articles for sale sent from the sending mechanism to the outlet 8. Reference numeral 11 denotes a tip portion 10 'of the inclined guide path 10.
And an induction heating cylinder provided between the discharge port 8 and the discharge port 8. 12
Is a high frequency induction coil integrally molded with the induction heating cylinder 11. Then, the upper end of the induction heating cylinder 11 has an inclined opening surface 13 and is inclined at an angle along the inclination of the inclined guide path 10. Further, the inclined opening surface 13 is configured so as not to project above an extension line of the inclined guide path 10, that is, a line connecting the tip portion 10 ′ of the inclined guide path 10 and the lower edge of the discharge port 8. Reference numeral 14 is a lifting device, which is a lifting plate portion 15 which is normally located at the bottom of the induction heating cylinder 11.
And the actuating rod 16 and the actuating rod 1 for imparting vertical movement thereto.
It is composed of a drive device 17 for driving 6 and the like. Therefore, the upper surface of the push-up plate portion 15 is formed in an inclined shape along the inclination of the inclined opening surface 13 of the induction heating cylinder 11. The push-up plate portion 15 is pushed up by the actuating rod 16 through the inside of the induction heating cylinder 11 to the inclined opening surface 13 (the position indicated by the dashed line in FIG. 7). 18 is a guide and locking device for the operating rod 16,
The operating rod 16 can be locked at the position where the push-up plate portion 15 reaches the inclined opening surface 13.

Next, the operation of the configuration of the above conventional example will be described. First,
The can a sent by the sales command rolls down the inclined guide path 10 as shown by the arrow in FIG. 7, and falls from the inclined opening surface 13 into the induction heating cylinder 11. The dropped can a ′ is received by the push-up plate portion 15 and heated in that state. When the heating is completed, the push-up device 14 is activated and the can a ′ is moved to the inclined opening surface 1
It is pushed up again until 3. When pushed up to the inclined opening surface 13, the push-up plate portion 15 is inclined, so that the can a ′ naturally rolls and is discharged from the discharge port 8 to the discharge port 6.

Problems to be Solved by the Invention However, in the above-mentioned configuration, since the high-frequency induction coil 12 and the can a ′ have poor adhesion, the heating efficiency is low, and the inclined induction path 10 drops into the induction heating cylinder 11. It is not easy to reliably guide the rolling can a into the induction heating cylinder 11 as well as it is not easy for the purchaser of the can to drink because the can is frothed or the can is deformed due to the impact and the can is purchased. If the sectional opening of 13 and induction heating cylinder 11 is enlarged, the position where the can a'is received by the push-up plate portion 15 is not determined, and one end of the can a'enters the inside of the high frequency induction coil 12 to cause can burning. It had a problem that it would end up.

To describe this can burning in detail, the induced currents generated on the wall surface of the can a ′ by the high frequency induction coil 12 are disconnected from each other at the joint portion when the wall surface is composed of the cylindrical portion, the lid and the bottom. Therefore, it occurs in the closed loop shape independently on the wall surface of each can. The induced current generated on the cylindrical wall surface of the wall surface of the can a ′ is generated by the magnetic flux generated from the high frequency induction coil 12 in the portion facing the cylindrical wall surface.

Here, if the length of the can a'is shorter than that of the high frequency induction coil 12, or if the can a'is not placed at an appropriate heating position, one end of the can a'will enter the inside of the high frequency induction coil 12. . At this time, the induced current in the longitudinal direction of the can a ′ is parallel to the longitudinal coil elements of the can a ′ among the plurality of coil elements forming the high frequency induction coil 12, and at an interval substantially equal to the interval between these coil elements. Flowing.

However, since the wall surfaces of the can a'are disconnected from each other, the induced current in the circumferential direction of the cylindrical wall flows in the vicinity of the joint between the lid and the bottom of the can a'and the cylindrical wall. Therefore, as the length of the can a ′ becomes shorter than that of the high frequency induction coil 12, the current density of the induced current in the circumferential direction flowing in the vicinity of the joint increases, and the vicinity of the joint has an abnormally high temperature and can burns.

Moreover, in the high frequency induction coil 12, when the coil element of the portion which is substantially parallel to the cylindrical wall surface of the can a ′ and does not face the cylindrical wall surface is, for example, on the lid side of the can a ′, this coil element The magnetic flux generated by the magnetic field is concentrated near the joint with the cylindrical wall surface on the side wall surface of the lid of the can a ′, and the induced current generated by this magnetic flux further increases the temperature near the joint. Further, when the coil element of the portion substantially parallel to the cylindrical wall surface of the can a'and not facing the cylindrical wall surface is on the bottom side of the can a ', the joint portion between the bottom side wall surface and the cylindrical wall surface is formed. The surrounding area gets even hotter.

Therefore, as described in Japanese Utility Model Laid-Open No. 53-121098, a can and a high frequency induction coil are introduced into a cylindrical high frequency induction coil by dropping the lid or the bottom of the can into the induction heating cylinder. Although there are those that perform relative positioning, even with this method, it is even more difficult to reliably guide the rolling can into the induction heating cylinder, and the induction is performed after passing through the inclined opening surface or at an angle. It has a problem that it falls into the heating cylinder and causes canning.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an automatic vending machine with an induction heating device capable of reliably guiding a canned beverage to a heating position of a coil.

Means for Solving the Problems In order to solve the above problems, the vending machine with an induction heating device according to the present invention has a bottom surface formed in a semi-circular shape so that the can wall of a cylindrical canned beverage extends along the longitudinal direction. It is provided with a bucket that is inclined to the side and a coil that is wound in a semi-arcuate shape and is installed in parallel on the bottom surface of the bucket.

Effect The present invention has the above-described structure to improve heating efficiency by placing a coil along the can wall, and by tilting the bucket, the position of the can in the longitudinal direction can be regulated. If the length in the longitudinal direction of the can is set to the shortest length of the can that can be heated, the coil can be installed at a position where one end of the can does not greatly enter the inside of the coil, and magnetic lines of force do not concentrate at one end of the can. , Can be prevented from burning.
