In addition, with conventional induction heating methods, a high-frequency type that supplies power to an induction heating coil at a predetermined sales temperature and storage temperature for canned products! In relation to the output of the high frequency oscillator (high frequency oscillator), the induction heating time required to heat and raise the temperature of the canned product to the sales temperature is determined, and the induction heating coil is energized by timer control.

[The invention tries to solve i! Title]

By the way, customers who purchase hot products from vending machines have individual differences in their preference for the hotness of their beverages, with some people preferring hot beverages while others prefer hot beverages that are slightly warmer. However, in the above-mentioned method of selling canned products by setting the sales temperature to, for example, 60°C, buyers can only purchase hot products at a certain temperature predetermined by the vending machine. Unable to meet the diverse demands of customers.

The present invention has been made in consideration of the above points, and is a hot product vending machine that adjusts the selling temperature of canned products according to the preferences of hot product purchasers, and can respond to various customer demands. The purpose is to provide

[Means to solve the problem]

In order to solve the above problems, the vending machine of the present invention includes a temperature setting means for selectively setting the selling temperature of canned products by the purchaser, and a temperature setting means for selectively setting the selling temperature of canned products, and a temperature setting means for selectively setting the selling temperature of canned products, and a temperature setting means for selectively setting the selling temperature of canned products. A control means for controlling energization of the induction heating coil to heat and raise the temperature.

[Function] In the above, the front of the vending machine cabinet has a high vending temperature setting means for setting the vending temperature.

A low selection temperature and temperature display lamp are installed, and when the purchaser presses the setting button according to his/her preference, the signal is input to the control unit and the sales temperature set by the purchaser is displayed on the lamp. At the same time, it is set by the control unit as a sales temperature setting value for induction heating performed in a subsequent sales operation. On the other hand, the energization control means for the induction heating coil compares the detection value of the temperature sensor that detects the heating temperature of the can product received by the induction heating coil during the product delivery operation and the sales temperature set value specified by the purchaser. In contrast, it controls the output of the high-frequency power supply that supplies power to the induction heating coil, and when it is confirmed that the canned goods discharged from the product storage section according to the sales command are transferred to the induction heating coil, the induction heating starts. Power is supplied to the coil to start induction heating, and when the temperature of the can product rises and the detected temperature reaches the sales temperature set value specified by the purchaser, the power supply to the induction heating coil is stopped.

As a result, a purchaser of a hot product can select and purchase either a hot beverage or a hot beverage according to his or her preference. In addition, in this case, we directly detected the heating temperature of the canned product and controlled the energization of the induction heating coil, so the customer's Heat to the specified sales temperature.

Can be sold at elevated temperature. In addition, by setting the standard selling temperature in advance, especially if the purchaser does not select a high or low selling temperature, the energization of the induction heating coil can be controlled using the standard selling temperature as the set value. It is possible to do so.
