[Problems to be solved by the invention]
However, the above-described conventional cooling control method using the cooling device of the paper pack vending machine has the following problems. That is, as described above, in the related art, the cooling device 30 is provided in the lower part of the refrigerator, and cooling is performed by circulating the cool airflow by the cooling device 30 throughout the refrigerator, as shown in FIG. Since the cool air flow blown by the blower fan 32 from the cooling device 30 circulates in order from the lower rear region to the front upper region in the refrigerator (in the direction of the dashed line arrow in the figure), the cooling temperature distribution in each region. Is the region (1) <region (2) <region (3) <region (4), and the cooling temperature of the NEXT product located in the region (4) where the cooling temperature should originally be the lowest is the highest. There is a problem that the temperature becomes high.
[0008]
Further, according to the invention described in Patent Document 1 described above, after the zone cooling for performing the lower part cooling of the inside of the refrigerator is completed first, the blowing direction of the cool air flow is switched by activating the blower switching guide means, so that the inside of the refrigerator is changed. The entire area cooling control for cooling the entire area is performed.

[0010]
As described above, in the cooling control method using the conventional cooling device, the cooling temperature of the NEXT product, which needs to be low due to the circulating air blow by the whole area cooling control, becomes high, and the temperature of the upper region becomes high. Regardless of the above, when the entire area cooling control is always performed, there is a problem that power consumption is more than necessary.
[0011]
The present invention has been made in view of the above circumstances, and based on the temperature detected by the first temperature detection means provided in the upper part of the vending machine inside, while operating the ventilation switching guide means, the inside of the refrigerator An object of the present invention is to provide a paper pack vending machine and a cooling control method using a cooling device, which can improve energy saving efficiency and reduce power consumption by optimally controlling a temperature distribution in an upper region and a lower region. .

(Step S530), (4) a second temperature detection step (Step S540), (5) a ventilation switching control step (Step S550), and (6) a cooling operation control step (Step S560). I have.
[0032]
First, each of the processing steps (1) to (6) will be briefly described. (1) The zone cooling step is a processing step of cooling a lower region in a refrigerator of a paper pack vending machine by a cool air flow. (2) The whole area cooling step is a control step of cooling the whole area in the refrigerator. (3) The first temperature detecting step is a processing step of detecting the temperature of the upper region in the refrigerator by the first thermistor 36 (first temperature detecting means) provided in the upper part of the refrigerator. (4) The second temperature detecting step is a processing step of detecting the temperature of the lower area in the refrigerator by the second thermistor 37 (second temperature detecting means) provided in the lower part of the refrigerator. (5) The air blow switching control step is a processing step of switching the cooling step from the whole area cooling control step to the zone cooling control step based on the temperature detected by the first thermistor 36 as the first temperature detecting means. (6) The cooling operation control step is a processing step of controlling the operation of the cooling device 30 (ON / OFF) based on the temperature detected in the second temperature detection step.
[0033]
Hereinafter, the cooling control method in the paper pack vending machine according to the present invention will be described in detail with reference to FIG. FIG. 6 is a flowchart showing a processing procedure of the cooling control method by the cooling device of the present invention.
[0034]
That is, as shown in the flowchart of FIG. 6, first, the state of the paper pack vending machine at the time of the initial pull-down is determined based on whether or not the power is on (step S610). When the power is on (step S610 affirmative), the zone cooling control is performed. The cooling control is performed (step S620). Here, the initial pull-down state refers to a timing at the time of normal loading, when a vending machine is newly installed, in addition to when the power is turned on.
[0035]
Further, as described above, the zone cooling control is a control for circulating and blowing cool air from the cooling device 30 toward a lower part in the refrigerator for the purpose of cooling NEXT products to be sold first. More specifically, as shown in FIG. 3A, by operating the air blowing switching means 42, cool air is sent out from the air blowing port 43 to cool the NEXT product.
[0036]
Next, the temperature T of the lower region in the refrigerator is detected by the second thermistor 37 (step S630). Then, based on the temperature detected by the second thermistor 37, it is determined whether or not the temperature T in the refrigerator is the reference cooling temperature T1 (10 ° C. or less) (step S640), and the temperature in the refrigerator is determined. If T is the reference cooling temperature T1 (10 ° C. or less) (Yes at Step S640), the entire area cooling control is performed by operating the air flow switching guide means 42 (FIG. 4) (Step S650). Here, as described above, the entire area cooling control is control for circulating and sending cool air from the cooling device to the entire area in the refrigerator.
[0037]
Thereafter, the process proceeds to step S660, where the first thermistor 36 detects the temperature T of the upper region in the refrigerator (step S660). Then, it is determined whether the temperature T detected by the first thermistor 36 is equal to or lower than 6 ° C. (step S670). If the temperature T is equal to or lower than the second reference cooling temperature according to the determination in step S670 (Yes in step S670), the zone cooling control process is performed again by the zone cooling control (step S680), and the next step S685 is performed. Transition. That is, the process of step S670 is a process of determining whether or not it is necessary to perform the entire region cooling control on the upper region in the refrigerator. When the upper region is kept at the reference cooling temperature, the zone cooling is performed. The control is switched to control to reduce the operation load of the cooling device.
[0038]
On the other hand, if the temperature T is not equal to or lower than the second reference cooling temperature in the determination in step S670, the process proceeds to step S685 without performing the zone cooling control in step S680, and the second thermistor 37 performs storage in step S685. A process for detecting the temperature T in the inside is performed.
[0039]
Then, it is determined whether or not the temperature T detected by the second thermistor 37 is the operating temperature of the cooling device 30 (Step S688). If the temperature T is the operating temperature of the cooling device 30 (Step S688) Affirmatively), the electromagnetic valve 52 (FIG. 4) is opened (Step S690), and the operation of the cooling device 30 is started (Step S695). , And the electromagnetic bubble 51 is opened to send the refrigerant to the evaporator 31.
[0040]
As described above, the paper pack product 5 stored in the direct stack type rack 4 can be sold as a cold product by zone heating, and the circulation of warm air to the upper space in the refrigerator can be suppressed to avoid cooling of an extra area. The operation rate and power consumption of the cooling device 30 can be reduced.
[0041]
In the above-described embodiment, the electromagnetic solenoid 50 is employed as the actuator for operating the air blowing guide means 42. However, the present invention is not limited to this. Operation can also be controlled.
[0042]
As described above, in the present invention, the first thermistor 36 for detecting the temperature of the upper region is provided in the upper part of the refrigerator, and the second thermistor 37 for detecting the temperature of the lower region in the lower part of the refrigerator. Since the switching between the entire area cooling control and the zone cooling control is controlled based on the temperature detected by the second thermistor 36, and the ON / OFF control of the cool air by the cooling device is performed based on the temperature detected by the second thermistor 37. Since the temperature of the area can be kept at the reference cooling temperature (10 ° C. or less) and the temperature of the lower area where NEXT products are stored can be kept at the appropriate temperature (0 to 2nd reference cooling temperature) suitable for sales, energy saving efficiency And power consumption can be reduced.
[0043]
Further, in the case where a product sold by a paper pack vending machine is a product such as a dairy product which needs to maintain its quality by low-temperature cooling, a product once cooled to 10 ° C. or less is cooled to 10 ° C. or more for some reason (for a certain period of time). When “continuation” is reached, the “health code” operates, but in the present invention, the operation of the “health code” can be reliably avoided.
[0044]

Since the temperature distribution in the upper area and the lower area can be controlled as a reasonable temperature area, it is possible to improve the energy saving efficiency and reduce the power consumption with the reduction of the cooling load by the whole interior and the cooling device. it can.
[0046]
Further, according to the paper pack vending machine according to claim 2, when the temperature detected by the first temperature detecting unit is lower than a reference cooling temperature, the air blowing switching control device is configured to control the air blowing guide. The function of switching the cooling control from the whole area cooling control to the zone cooling control by the operation of the switching means is provided, so that the temperature of the upper area is set to the reference cooling temperature (10 ° C. or less) and the lower area of the lower area where NEXT products are stored. Since the temperature can be kept cool to an appropriate temperature suitable for sale (0 to the second reference cooling temperature), energy saving efficiency can be improved and power consumption can be reduced.
[0047]
Further, according to the paper pack vending machine according to claim 3, the cooling device is constituted by the wind tunnel having the cooler and the blower fan therein, and the wind tunnel is connected to the wind tunnel. Since the air supply duct is provided and the air supply switching guide means is provided inside the air supply duct, the switching between the entire area cooling control and the zone cooling control can be reliably performed by the operation of the air supply switching guide means.
[0048]
Further, according to the paper pack vending machine according to claim 4, the blower guide switching means includes a blower guide plate and an electromagnetic solenoid for operating the blower guide plate, and is controlled by the electromagnetic solenoid to turn on / off. Since the switching of the cool air flow can be performed, the switching between the entire area cooling control and the zone cooling control can be easily performed by operating the electromagnetic solenoid.
[0049]
Further, according to the cooling control method by the cooling device according to the fifth aspect, the switching from the entire area cooling control step to the zone cooling control step is performed by the air flow switching control step based on the temperature detected in the first temperature detection step. As a result, it is possible to control the temperature of each area in the refrigerator in an appropriate cooling temperature zone, and to reduce the power consumption due to the reduction in the operation rate of the cooling device by suppressing the cooling to an extra upper area. Can be planned.
