The refrigerant that has reached the left internal heat exchanger 24c exchanges heat with the internal air of the left internal 3c while passing through the heat exchanger, and dissipates heat to the internal air to condense. Thereby, the internal air of the left warehouse 3c is heated.

According to this, the chamber temperature of the heating chamber 3 (the left chamber 3c) changes in the increasing direction.

  When the compressor 21 is stopped driving (step S311: No), the control means 70 receives the internal temperature (heating chamber temperature) of the heating chamber 3 (left chamber 3c) from the internal temperature sensor 60. Then (step S315: Yes), it is determined whether the temperature in the heating chamber is equal to or lower than the heating adjustment lower limit temperature that is the lower limit value of the heating adjustment temperature range read from the memory 80 (step S316).

  When the temperature in the heating chamber is equal to or lower than the heating adjustment lower limit temperature (step S316: Yes), the control means 70 drives the compressor 21 (step S317), and then returns the procedure to end the current process.

It is made possible (step S209), and then the procedure is returned to end the current process.

  In other words, the control means 70 does not change the product temperature until the inside temperature of the product container 3 reaches the preset off temperature even when the energy saving operation time for performing the low level cooling operation control and the low level heating operation control has elapsed. The suspension of sales continues.

  As described above, according to the control device of the vending machine according to the embodiment of the present invention, the controller 70 determines that the internal temperature of the refrigerator 3 is equal to or higher than the cooling adjustment upper limit temperature during the set energy saving time. In this case, the compressor 21 is driven, while when the internal temperature is equal to or lower than the cooling adjustment lower limit temperature, the low level cooling operation control for stopping the compressor 21 is performed.

Therefore, it is possible to prevent the quality deterioration of the product while reducing the power consumption.

  In addition, by adjusting the internal temperature of the refrigerator 3 (the right warehouse 3a and the middle warehouse 3b) to the cooling adjustment temperature range during the energy saving operation time, the power supply is cut off as in the conventional case, while the energy saving operation is performed. It is possible to shorten the time during which the internal temperature is lowered to the cooling temperature range after a lapse of time.

  Further, according to the control device of the vending machine, the control means 70 drives the compressor 21 when the internal temperature of the heating chamber 3 is equal to or lower than the heating adjustment lower limit temperature during the set energy saving time. On the other hand, when the internal temperature is equal to or higher than the heating adjustment upper limit temperature, since the low level heating operation control for stopping the driving of the compressor 21 is performed, the internal temperature of the heating chamber 3 (left chamber 3c) is set to a desired value. The temperature can be adjusted to the heating adjustment temperature range, the product temperature of the product can be maintained within a preferable range, and power consumption can be reduced. Therefore, it is possible to prevent the quality deterioration of the product while reducing the power consumption.

  In this energy saving operation process, the control means 70 uses the built-in clock function to display a warning through the sales operation control unit 73 when the current time has passed the energy saving operation start time (step S211: Yes). It will be in a state (step S212, step S213).

  As a specific example of the warning display in this way, the sales operation control unit 73 flashes the lamp 64 in preparation for blinking, or the integrated display 61 displays, for example, “Now energy saving operation is in progress. "Please be careful." As specific means for stopping the sale of the product, the sales operation control unit 73 turns on the sold-out lamp 63 or the ready lamp 64 and invalidates the selection button 62 to stop the money processing apparatus 65 from accepting money. Let In the energy saving operation state, the control means 70 performs the low level cooling operation control and the low level heating operation control as described above (see FIGS. 10 and 11).

  Thereafter, when the current time has passed the energy saving operation end time using the built-in clock function (step S214: Yes), the control means 70 causes the compressor 21 to output 100% through the cooling / heating operation control unit 74. Full power drive is performed (step S215). When the compressor 21 is driven at full power in this way, the refrigerant circulates through the refrigerant circuit 10, and the internal temperature of the cooling chamber 3 (the right chamber 3a and the middle chamber 3b) changes in the decreasing direction, and the heating chamber 3 (left The internal temperature of the storage 3c) changes in the increasing direction. The detection result of the internal temperature of each commodity storage 3 is input from the internal temperature sensor 60 (step S216), and the internal temperature of each of the cooling chambers 3 (the right storage 3a and the central storage 3b) is read from the memory 80. When it is below the cooling off temperature of the cooling temperature information and the inside temperature of the heating compartment 3 (left compartment 3c) is above the heating off temperature of the heating temperature information read from the memory 80 (step S217: Yes, step S218: Yes) ), The control means 70 hides the warning display through the sales operation control unit 73 (step S219), that is, turns off the preparing lamp 64 or erases the display of the integrated display 61, and then performs the procedure. To end the current process.

  Thus, it is possible to prevent a reduction in sales opportunities of products by continuing to sell products even in an energy saving operation state.

  In the above-described embodiment, the energy-saving operation processing in the case of performing the HCC operation has been described. However, in the energy-saving operation processing in the case of performing the CCC operation, the processing in step S208 (step S218) may be omitted, and low-level heating is performed. Operation control (refer to Drawing 11) should just be omitted.

  In the above-described embodiment, the compressor 21 is driven after the current time has passed the energy saving operation end time in the energy saving operation processing. However, in the present invention, several minutes to several tens of minutes before the energy saving operation end time. The compressor 21 may be driven when the current time elapses from the transition time provided in FIG.

  In the above-described embodiment, since the refrigerant circuit 10 of the vending machine to be applied has a heat pump function, driving and stopping the driving of the compressor 21 drives the cooling means and the heating means. In the present invention, the product in the heating cabinet is heated by a heater built in the heating cabinet, and the refrigerant circuit 10 serves as a refrigeration cycle for cooling the product in the cooling cabinet 3. It may be applied to a functioning vending machine. In addition, when the heater is driven by PID control to heat the atmosphere inside the heating chamber, in low-level heating operation control, the heater is PID controlled using the heating adjustment temperature input through the input unit as the target temperature. It is preferable to drive by.

  In the embodiment described above, the energy saving operation time is set by inputting a predetermined time zone through the input means 66. However, in the present invention, patterns relating to a plurality of types of energy saving operation time are stored in advance in the memory. The energy saving operation time may be set by selecting any pattern by operating the input unit of the input means. In such a case, when the input unit of the input unit is operated, the control unit that has input the setting command of the energy saving time zone pattern from the input unit through the input control unit reads out and outputs the energy saving time zone pattern from the memory. Each pattern is displayed on the display unit through the control unit. When the operator selects any one of the energy saving time zone patterns displayed by operating the input unit, a selection command is given to the control means. The control means to which such a selection command is given sets the energy saving operation time by giving each part the energy saving time zone pattern selected through the input control unit.

  In the embodiment described above, the cooling adjustment upper limit temperature, the cooling adjustment lower limit temperature, the heating adjustment lower limit temperature, and the heating adjustment upper limit using conditional expressions (1) to (4) by inputting the cooling adjustment temperature and the heating adjustment temperature. The temperature is calculated and the cooling adjustment temperature range and the heating adjustment temperature range are set. However, in the present invention, the cooling adjustment temperature and the heating adjustment temperature are not input, and the cooling adjustment upper limit temperature, the cooling adjustment lower limit temperature, and the heating adjustment are set. The cooling adjustment temperature range and the heating adjustment temperature range may be set by setting the lower limit temperature and the heating adjustment upper limit temperature experimentally or empirically in advance.
