    Abstract: PURPOSE:To always cell a canned beverage at a stable temperature by multiplying the output of the input current detecting circuit of a voltage type resonant inverter circuit by the output of an input voltage detecting circuit, and controlling the pulse width of the voltage type resonant inverter circuit so that the output may become a determined voltage. CONSTITUTION:The input voltage of a voltage type resonant inverter circuit 6 detected by an input voltage detecting circuit 21 is multiplied by an input current detected by an input current detecting circuit 11 by means of a multiplier 24, and the pulse width of the voltage type resonant inverter circuit 6 is controlled by an oscillation control circuit 18 so that the output of the multiplier 24 may become the voltage determined by a reference voltage circuit 15. Thus the heating output is made constant, and without the effect of the input voltage, a canned beverage 2 can be heated on the constant heating output for a constant time.

    Abstract: PURPOSE:To prevent a selling oppotunity from being decreased and to keep the temperature of can drink constant by storing a time, in which the can drink is put in, to a sell memory, computing a cold reserving time in the commodity carrying device of the can drink to be next sold and deciding whether the next can drink can be sold or not. CONSTITUTION:A control circuit 17 stores the put-in time in a sell memory 20 for each can drink according to a signal from a put-in detection circuit 16. When it is finished to fill up the can drink, a sales deciding circuit 19 compares the time data, which are stored to the sell memory 20, with a present time and decides whether the can drink to be next sold is kept cold in the commodity carrying device only for a time determined in advance or not. Then, it is judged whether the can drink can be sold or not. Thus, even when the can drink is remained in the commodity carrying device and the can drink is filled up, concerning the can drink to be already kept cold, it is not prohibited to sell the can drink. Then, for the can drink to be newly put-in, since the can drink is kept cold while the remained can drink is sold, the time of the sales prevention is decreased.

    Abstract: PURPOSE:To make it possible to sale various kinds of drinks by deciding the sort of a canned drink by a sort deciding means based upon the temperature rise ratio of the can wall temperature of the can drink and heating the can up to the can wall temperature of a HOT sales temperature in accordance with the sort of the contents of the drink. CONSTITUTION:The can wall temperature of a canned drink is detected by a temperature detector 7, the liquid temperature rise ratio of the can drink is measured by a temperature rise ratio measuring means 9, the sort of the canned drink is decided by a sort deciding means 10 based on the measured result, and the detecting level of the detector 7 to end heating is determined by a detecting level determining means 11 based on the decided result. A stop signal generating means 12 compares the control signal from the means 11 with the detecting signal from the detector 7 and generates a stop signal for stopping a high frequency power converter 3 to control the converter 3. Consequently, the canned drink can be reached to a prescribed HOT sales temperature independently of the sort of the canned drink.

    Abstract: PURPOSE:To improve the working rate of the title automatic vending machine by automatically discriminating the type (structure) of the can of a canned drink and controlling a heating output according to the type of the can. CONSTITUTION:When a canned drink 2 is to be heated, the type of the can of the canned drink 2 is decided by a can deciding means 20 based on an input voltage value detected in a voltage detecting circuit 17 and a current value, which is detected in a current detecting circuit 18 and generates in either a heating coil 1 or a power switching semiconductor 10. Heating output quantity is determined by a heating output determining means 21 based on this decided result, and the heating output quantity of an inverter circuit 14 is controlled by a driving means 22 based on a control signal from this heating output determining means 21. Consequently, it becomes possible to vary the heating output quantity and inductively heat the canned drink 2 automatically according to the type (structure) of the can. Thus, the working rate of the automatic vending machine can be improved.

    Abstract: PURPOSE:To securely detect power source abnormality and to prevent a power semiconductor element from breaking by providing a voltage detecting circuit which sends out its output in three stages and specific integration circuits which are connected with respective outputs. CONSTITUTION:The voltage detecting circuit 7 detects a power source input and sends out three stages of outputs High, Mid, and Low as the detected voltage. Further, the 1st and 2nd integration circuits 8 and 9 are connected to the High and Low outputs of the voltage detecting circuit 7 and the 3rd integration time 10 which has a smaller time constant than the 1st and 2nd integration circuits 8 and 9 is connected to the Mid output. Therefore, only the 3rd integration circuit 10 varies abruptly in case of the power source abnormality, and the output of the 3rd integration circuit 10 becomes larger than the output 8 of the 1st integration circuit in case of a lightning surge and below the output of the 2nd integration circuit 9 in case of an instantaneous power failure, so that they are protected by the outputs of 1st and 2nd comparators 11 and 12 respectively. Consequently, the power semiconductor element is securely protected in case of the power failure abnormality and prevented from breaking.

    Abstract: PURPOSE:To vend many kinds of can drinks whose content quantities are different at the same heating degree by deciding the content quantity of the can drink and controlling a heating time by a result of this decision. CONSTITUTION:At the time of heating a can drink 2, a voltage generated in a power switching semiconductor 4 of an inverter circuit 6 is detected by a voltage detector 9. Based on this detection value, the content quantity of the can drink 2 is decided by a can content quantity deciding means 11, and based on a result of this decision, a heating time is determined by a heating time determining means 12. Subsequently, by a signal from this heating time determining means 12, an oscillation time of the inverter circuit 6 is controlled by a driving means 13, and heating is executed at an appropriate time so that a heating temperature becomes constant automatically in accordance with the content quantity of the can drink 2.
