Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling and heating device for an automatic vending machine, which cools or heats a product storage chamber to sell products.

[0002]

2. Description of the Related Art In recent years, with the diversification of vending machine sales products, the number of products that can sell cold products and hot products has increased, and due to rising global environmental problems,

No. 62 publication.

The conventional vending machine will be described below with reference to the drawings.

FIG. 17 is a schematic configuration diagram of a conventional vending machine. In FIG. 17, reference numeral 1 is the main body of the vending machine.
The product storage chamber 1A is provided with a cooler 2A and a blower 3A exclusively for the cooling mode, and the product storage chamber 1B is provided with a cooler 2B, a heater 4 and a blower 3B for both the cooling mode and the heating mode.

The coolers 1A and 1B are a common compressor 5
Refrigerant is separately supplied from A, the cooler 2A directly and without the solenoid valve, and the cooler 2B has the solenoid valve 6
Is connected to the compressor 5A via each refrigerant pipe 8.

Reference numeral 9 denotes a condenser, which is a cooling means 5 and a cooling device 2.
A is connected between the solenoid valve 6. The product storage room 1
Room temperature sensors 10, 1 consisting of thermistors are shown in A and 1B.
1 is installed respectively, and the controller 12 controls the compressor 5A and the solenoid valve 6 to be turned on and off based on these temperature signals.

Here, the controller 12 includes the coolers 2A and 2B.
An upper limit temperature and a lower limit temperature for on / off control are input and stored. The product storage chamber 1B is provided with a switch 13 for switching between cooling and heating. When the switch 13 is turned on, an energizing circuit for the heating means 4 is formed.

A heat insulating wall 14 separates the product storage chambers 1A and 1B from each other.

The operation of the vending machine having the above structure will be described below.

The blowers 3A and 3B are always operating.
When the switch 13 is on the cooling side and both the product storage chamber 1A and the product storage chamber 1B are set to be cooled, the solenoid valve 6 is opened and the compressor 5A is operated. As a result, the refrigerant is supplied to both the coolers 2A and 2B, and the product storage chambers 1A and 1B are cooled. After that, when the temperature of the product storage chamber 1B becomes lower than the lower limit temperature, the solenoid valve 6 is closed, and when the temperature of the product storage chamber 1A becomes lower than the lower limit temperature, the compressor 5A is stopped. In this way, the product storage chambers 1A and 1B are maintained at the cooling temperature in the range of the lower limit temperature to the upper limit temperature.

Next, when the switch 13 is on the heating side and the product storage chamber 1A is set to cool and the product storage chamber 1B is set to warm, the solenoid valve 6 is closed to stop the supply of the refrigerant to the cooler 2B. . Further, the heating means 4 is energized, and when the heating upper limit temperature is reached, the energization is stopped.

[0013]

However, in the above configuration, when one of the product storage chambers is set to be cooled and the other product storage chamber is set to be heated, heat insulation due to a temperature difference between the product storage chambers 1A and 1B is performed. Due to the increase in the amount of heat absorbed by the wall 14, the operation rates of the cooling means 5 and the heating means 4 are increased, which causes a problem of increasing the electricity bill.

The operation of the cooling and warming device of the vending machine having the above-described structure will be described below with reference to the flowchart of FIG.

First, when the cooling / warming device of the vending machine is turned on, the control means 18 detects that the power is turned on (S1), and starts counting the time of the timer 16 (S2). An operation signal is output to the cooling means 5 (S3). Then, the temperature of the product storage room 1A is detected by the product storage room temperature detection means 15A (S4), and the control means 18 determines whether or not the room temperature of the product storage room 1A becomes lower than the preset temperature of the product storage room 1A. Is determined (S5).

When the room temperature of the product storage room 1A is equal to or higher than the specified temperature, the process returns to step S3, and this routine is repeated until the temperature becomes lower than the specified temperature. If the room temperature of the product storage room 1A is lower than the specified temperature, the control means 18 stops the power supply to the cooling means 5 (S6), and the power supply time from the start of the power supply measured by the timer 16 is stored in the storage means 17. It is stored (S7). The power supply time of this time is stored in the storage unit 1.
Instead of storing the data in No. 7, if the previous power feeding time data is stored, this data is reset.

Next, the control means 18 starts the time counting of the timer 16 (S8) and outputs an operation signal to the heating means 4 (S9). Then, the temperature of the product storage room 1B is detected by the product storage room temperature detection means 15B (S10), and the room temperature of the product storage room 1B is determined as the product storage room 1B.
The control means 18 determines whether the temperature has become higher than the specified temperature (S11).

If the room temperature of the product storage room 1B is lower than the specified temperature, the process returns to step S9, and this routine is repeated until the room temperature rises to the specified temperature. If the room temperature of the product storage room 1B is higher than the specified temperature, the control means 18 stops the power supply to the heating means 4 (S12), and the timer 16 is operated.
The power feeding time from the start of power feeding measured by
No. 7 is stored (S13). Then, if the previous power supply time is stored, this data is reset.

The above operation is performed until the room temperature of each of the product storage chambers 1A and 1B exceeds the preset specified temperature by turning on the cooling and heating device of the vending machine. In step S1, the power is not turned on, but the product storage chamber 1 after the power is turned on, which will be described later.
In the operation state in which the room temperature of A and 1B is kept constant, the operation immediately after the power is turned on is skipped, and the control after step S14 is executed.

Next, the flow of operation control for realizing energy saving while keeping the room temperature of each of the product storage chambers 1A and 1B constant will be described with particular reference to FIGS.

After the power is turned on, when the product storage chambers 1A and 1B exceed their specified temperatures, the product storage chamber temperature detecting means 15A detects the temperature inside the product storage chamber 1A (S1).

6) If the temperature is equal to or higher than the specified temperature, the control means 18 outputs an operation signal to the cooling means 5 (S17).

In step S18, step S17
Previously, the heating means 4 was operating, and the control means 18 determines whether the cooling means 5 and the heating means 4 are both operating. If both the cooling means 5 and the heating means 4 are in operation, the process jumps to step S26 described later. If the heating means 4 is not in operation and only the cooling means 5 is in operation, the timer 16 is started in the next step S19 to measure the elapsed time of operation of the cooling means 5 and the cooling operation time.

Then, the temperature in the product storage chamber 1B is detected by the product storage chamber temperature detection unit 15B (S20), and the control unit 18 compares the detected room temperature in the product storage chamber 1B with the specified temperature. (S21). And product storage room 1
If the room temperature of B is higher than the specified temperature, the control means 18 outputs a stop signal to the heating means 4 (S22), ends the processing routine, and returns to the start. Also, step S
In 21, if the room temperature of the product storage chamber 1B is lower than the specified temperature, the control means 18 outputs an operation signal to the heating means 4 (S23).

In step S24, the control means 18 confirms whether the cooling means 5 is also in operation, that is, whether the cooling means 5 and the heating means 4 are simultaneously supplied with power. When the cooling means 5 is not supplied with electric power and only the heating means 4 is supplied with electric power, the timer 16 is started in order to measure the elapsed time of the operation of the heating means 4, that is, the heating operation time (S25). ), The processing routine ends, the process returns to the start, and the processing is repeated from step S1.

Here, if the cooling means 5 is also supplied with power, the process proceeds to the next step S26. In the case of the processing from step S18, the total time of the elapsed time and the previous operation time of the heating means 4 which is operating before the cooling means 5 is compared with the previous operation time of the cooling means 5. Further, in the case of the processing from step 24, the elapsed time up to this point of the cooling means 5 operating before the heating means 4 and the total time of the previous operation time, and the previous operation time of the heating means 4 are calculated. Compare.

When the operating time of the cooling means 5 is long, the control means 18 outputs a stop signal to the cooling means 5 (S2).
7). When the cooling means 5 is stopped, the heating means 4 is supplied with power and the temperature inside the product storage chamber 1B is detected (S2).
8), it is determined by the control means 18 whether or not the specified temperature set in the product storage chamber 1B has been exceeded (S29). As a result of the determination in step S29, if the room temperature of the product storage chamber 1B does not exceed the specified temperature, the process returns to step S28. As a result of the determination, if the room temperature of the product storage room 1B exceeds the specified temperature, the power supply from the control means 18 to the heating means 4 is stopped (S
30), instead, power supply to the cooling means 5 is started, cooling operation is performed (S31), and the timer 16 is started (S32).

Then, the temperature inside the product storage chamber 1A is detected (S33), and it is determined by the control means 18 whether the temperature exceeds the specified temperature set in the product storage chamber 1A (S3).
4). As a result of the determination, if the room temperature of the product storage room 1A does not exceed the specified temperature, the process returns to step S33. If the room temperature of the product storage room 1A exceeds the specified temperature as a result of the determination, the power supply from the control means 18 to the cooling means 5 is stopped (S
35), the process is terminated and the process returns to the start.

In step S26, when the operating time of the heating means 4 is longer than the operating time of the cooling means 5, the control means 18 outputs a stop signal to the heating means 4 (S3).
6). When the heating means 5 is stopped, power is supplied to the cooling means 5, and the temperature inside the product storage chamber 1A is detected (S3).
7) The control means 18 determines whether or not the specified temperature set in the product storage chamber 1A has been exceeded (S38). As a result of the determination in step S38, if the room temperature of the product storage chamber 1A does not exceed the specified temperature, the process returns to step S37. As a result of the determination, if the room temperature of the product storage room 1A exceeds the specified temperature, the power supply from the control means 18 to the cooling means 5 is stopped (S
39) Instead, the power supply to the heating means 4 is started, the warming operation of the product storage chamber 1B is performed (S40), the timer 16 is started, and the warming operation time is measured (S32).

Then, the temperature inside the product storage chamber 1B is detected (S42), and it is judged by the control means 18 whether the temperature exceeds the specified temperature set in the product storage chamber 1B (S4).
3). As a result of the determination, if the room temperature of the product storage chamber 1B does not exceed the specified temperature, the process returns to step S42. If the room temperature of the product storage room 1B exceeds the specified temperature as a result of the determination, the power supply from the control means 18 to the heating means 4 is stopped (S
44), the process is terminated and the process returns to the start.
