On the other hand, a control circuit 30 is provided. The control circuit 30 includes a CPU, a RAM, a ROM, and the like. The control circuit 30 is connected to the compressor 12, the refrigerant solenoid valves 14, 15, the heaters 16, 17, and the display motor 27. The heaters 16 and 17 are connected to a control circuit 30 via limiters 31 and 32, respectively. The control circuit 30 includes a left ventricle thermistor 3
3. The right ventricle thermistor 34 and the outside air temperature thermistor 35 are connected, and the summer microswitch 36 and the winter microswitch 37 are connected. As shown in FIG. 5, these micro switches 36 and 37 are arranged on the rotation locus of the arm 28, and are turned on / off according to the presence or absence of the contact of the arm 28. Further, a setting key 38 is connected to the control circuit 30.

The control circuit 30 has the following functions by executing each program of the sales control flowchart shown in FIGS. That is, a timing determining function for determining whether it is time to switch the product to heating or cooling, and a switching function for switching the product to heating or cooling when the timing to switch to heating or cooling has arrived by the determination of the timing determining function. And a display switching function of issuing a command to switch the display of heating or cooling when it is time to switch to heating or cooling according to the determination of the timing determining function. Here, the timing determination function is to switch to heating or cooling when the average value of the detected temperatures of the outside air temperature thermistor 35 reaches each set temperature of outside air to be switched to heating or cooling for a predetermined period, for example, 10 consecutive days. is there. In the timing determination function, a date for switching to heating or cooling is set as an annual calendar. Further, the control circuit 30 has a timer function.

Next, the operation of the vending machine configured as described above will be described with reference to the sales control flow charts shown in FIGS.

The timing of heating or cooling is set and input in advance by operating the setting key 38. For example, the input is set such that the left chamber 6 is heated from November 1 and the left chamber 6 is cooled and the right chamber 7 is cooled annually from April 1. In addition, the switching timing is set and input at midnight. At the same time, when the average value of the detected temperature of the outside air temperature thermistor 35 per day becomes lower than each set temperature of the outside air temperature for continuously switching to heating or cooling for a predetermined period of time, for example, 20 degrees or less, heating is performed.
When the temperature exceeds the predetermined value, a continuous number of days, for example, 10 days, for switching to cooling is set and input. or,
The timer function of the control circuit 30 performs a timer operation to set the date and time.

First, the timing determining function of the control circuit 30 determines in step s1 whether the switching to heating or cooling has been performed, and in the next step s2, determines whether it is the switching time.
Next, in step s3, the control circuit 30 takes in the detected temperature of the outside air temperature thermistor 35 at every predetermined sampling period and sequentially stores it in the RAM to calculate the average outside air temperature for one day. When the average outside temperature reaches the set temperature of the outside temperature for continuously switching to heating or cooling, for example, for 10 consecutive days,
The control circuit 30 executes programs for each of the left and right rooms 6 and 7. That is, switch the product to heating or cooling
And the detected temperature of the outside temperature thermistor 35
The average outside temperature is continuously heated for 10 days for example.
Is switched to cooling.
Road 30 heats products for each room of left room 6 and right room 7
Or, switch to cooling. Since these programs have the same contents, the program of the left ventricle 6 will be described in this embodiment.

The control circuit 30 determines in step s4 whether or not there is a switching setting.
The process proceeds to steps s5 and s6 to determine whether the setting content stored in the RAM is “HOT” or “COLD”. In step s4, the control circuit 30 determines whether or not there is a switching setting. If the switching has been set, the control circuit 30 proceeds to steps s7 and s8 to determine whether it is a hot operation day or a cold operation day.

Next, a case where the result of determination in step s7 is a hot operation day will be described with reference to FIG. In this case, the summer microswitch 36 is on. The control circuit 30 turns off the refrigerant electromagnetic valve 14 of the left chamber 6 and starts energizing the heater 16 of the left chamber 6 in step s9. Next, in step s10, the control circuit 30 determines whether or not the winter microswitch 36 of the left ventricle has been turned on. If it has not been turned on, the process proceeds to step s11 to rotate the display motor 27.

When the display motor 27 rotates,
The arm 28 pivots in the direction of the arrow (a) and separates from the contact of the summer microswitch 36 to release the winter microswitch 37.
Contact with. At the same time, the rotation of the arm 28 causes the slide moving plate 20 to slide in the direction of the arrow (b).
By this slide movement, the letters “HOT” are displayed on each display window 1.
9-1, 19-2...

Next, the control circuit 30 performs a sold-out display in step s12, receives the detected temperature of the left ventricle thermistor 33 in the next step s13, judges whether the temperature has reached the hot set temperature, and reaches the hot set temperature. If not, the sold-out display is continued in step s14. or,
The control circuit 30 determines in step s13 that the left ventricle thermistor 3
When it is determined that the detected temperature of 3 has reached the hot set temperature,
In step s15, the sold-out display is turned off. Then, in step s16, the control circuit 30 determines whether the detected temperature of the left ventricle thermistor 33 is equal to or higher than the hot set temperature. If the detected temperature is equal to or higher than the hot set temperature, the control circuit 30 cuts off the power supply to the heater 16 in step s17. If it is less than or equal to the above, the power supply to the heater 16 is continued in step s18.

Next, a case where the result of determination in step s8 is a cold operation day will be described with reference to FIG. In this case, the winter microswitch 37 is on. The control circuit 30 turns on the refrigerant solenoid valve 14 of the left chamber 6 and cuts off the power supply to the heater 16 of the left chamber 6 in step s19. Next, in step s20, the control circuit 30 determines whether or not the summer micro switch 36 of the left ventricle is turned on. If not turned on, the process proceeds to step s21 to rotate the display motor 27.

When the display motor 27 rotates,
The arm 28 pivots in the direction of the arrow (a), and separates from the contact of the winter microswitch 37 to remove the summer microswitch 36.
Contact with. At the same time, the rotation of the arm 28 causes the slide moving plate 20 to slide in the direction of the arrow (b).
By this slide movement, the characters of each COLD are displayed on each display window 1.
9-1, 19-2...

Next, in step s22, the control circuit 30 performs a sold-out display, and in the next step s23, receives the detected temperature of the left ventricle thermistor 33, determines whether the temperature has reached the cold set temperature, and reaches the cold set temperature. If not, the sold-out display is continued in step s24.
When the control circuit 30 determines in step s23 that the detected temperature of the left ventricle thermistor 33 has reached the cold set temperature, it turns off the sold-out display in step s25.
Then, in step s26, the control circuit 30 determines whether the detected temperature of the left ventricle thermistor 33 is equal to or higher than the cold set temperature.
In step s28, the refrigerant solenoid valve 14 is turned off. If the temperature is equal to or lower than the cold set temperature, the refrigerant solenoid valve 14 is turned off in step s28.

The control circuit 30 controls the compressor 12 in accordance with a compressor control flowchart shown in FIG. That is, the control circuit 30 turns on the compressor 12 in step f3 if any one of the refrigerant solenoid valves 14, 15 of the left chamber or the right chamber is turned on in steps f1 and f2. Make it work.

As described above, in the above-described embodiment, it is determined whether it is time to switch the heating or cooling of the product 2 and when the timing of switching to heating or cooling has come, the heating or cooling of the product 2 is performed. Can be switched and "HO
