Description

  The present invention relates to an improvement in a vending machine that stores and sells products such as paper-packed beverages.

  Conventionally, as a vending machine that stores and sells products such as paper-packed beverages, it includes a product storage, a product storage shelf, a cooler, a fan, a temperature sensor, and a product temperature sensor. Is known.

  A goods storage has the heat insulation structure defined in the inside of the main body cabinet which is a vending machine main body. The product storage shelf is disposed inside the product storage and stores products along the vertical direction. In the product storage shelf, the product stored at the lowest position is a product that may be taken out at the next sales opportunity. The cooler is disposed in the product storage and cools the internal atmosphere of the product storage. This cooler constitutes a refrigeration cycle that circulates a refrigerant and a refrigerator disposed in a chamber inside the main body cabinet and outside the product storage, and evaporates the refrigerant that passes therethrough to evaporate the product storage. The internal atmosphere is cooled. A fan is arrange | positioned at goods storage and blows the internal atmosphere cooled with the cooler. The temperature sensor is attached to the cooler and detects the temperature (cold air temperature) of the internal atmosphere cooled by the cooler. The product temperature sensor is disposed in the vicinity of the discharge port of the product paid out from the product storage shelf, and detects the temperature of the product passing through the discharge port.

  In such a vending machine, the refrigerator is driven or stopped so that the temperature difference between the product temperature detected by the product temperature sensor and the cold air temperature detected by the temperature sensor is within a predetermined range. The product is maintained at an appropriate temperature (see, for example, Patent Document 1).

  However, in the vending machine as described above, the drive of the refrigerator is controlled so that the temperature difference between the product temperature detected by the product temperature sensor and the cold air temperature detected by the temperature sensor is within a predetermined range. Therefore, products other than products that may be carried out at the next sales opportunity, that is, upper products including the highest product stored in the product storage shelf are also cooled to the same temperature level as the lowest product. There was a fear of being done.

  In more detail about this, it is preferable that the product at the bottom of the products stored in the product storage shelf is maintained at an appropriate temperature for products that may be carried out at the next sales opportunity. For example, if the product at the top is unlikely to be carried out immediately and is cooled to such an extent that the quality is not deteriorated, it is not necessarily cooled to an appropriate temperature. However, just controlling the drive of the refrigerator so that the temperature difference between the temperature detected by the product temperature sensor and the temperature detected by the temperature sensor is within a predetermined range as in the vending machine described above. Of the products stored in the product storage shelf, the products on the upper side may also be cooled to the same temperature level as the products at the bottom. Cooling to the same temperature level as a product that may be transported at the next sales opportunity to a product that is unlikely to be transported immediately in this way is not sufficiently high in operating efficiency. There has been a risk of increasing energy consumption accompanying cooling of the product.

Detected first detection When the degree exceeds the predetermined upper limit value of the first reference temperature range, the cooling amount by the cooler is increased, while the first detected temperature is less than the lower limit value of the first reference temperature range. The cooling control for reducing the cooling amount by the cooler and the second detection temperature detected by the second temperature detection means are predetermined and set to a temperature range higher than the first reference temperature range. When the upper limit value of the reference temperature range is exceeded, the circulation amount by the circulation means is increased, while when the second detected temperature is less than the lower limit value of the second reference temperature range, the circulation amount by the circulation means is increased. And a control means for performing a circulating control to decrease.

In this case, the cooling control is performed to stop the operation of the refrigerator and reduce the cooling amount by the cooler.

  According to the present invention, the control unit increases the cooling amount by the cooler when the first detected temperature detected by the first temperature detecting unit exceeds the predetermined upper limit value of the first reference temperature range. When the first detected temperature is less than the lower limit value of the first reference temperature range, the cooling control for reducing the cooling amount by the cooler and the second detected temperature detected by the second temperature detecting means are determined in advance. When the upper limit value of the second reference temperature range that is higher than the first reference temperature range is exceeded, the circulation amount by the circulation means is increased, while the second detected temperature is the lower limit value of the second reference temperature range.

And this process is complete | finished.

  According to this, the amount of cooling of the internal air of the product storage 3 by the evaporator 6 is increased, and the temperature of the internal air of the product storage 3 is gradually lowered.

  When the lower temperature does not exceed the upper limit value of the first reference temperature range (step S109: No), the cooling control unit 31 maintains the drive stop of the compressor 7 (step S111), returns the procedure, and this time Terminate the process.

  In the circulation control shown in FIG. 6, when the circulation control unit 32 of the control unit 30 inputs the upper temperature detected by the upper thermistor 27 through the input processing unit 321 (step S201: Yes), the circulation control unit 32 The second reference temperature information is read from the circulation control memory 32a through 322 (step S202), and it is compared whether or not the upper temperature input in step S201 exceeds the upper limit value of the second reference temperature range (step S203).

  When the upper temperature exceeds the upper limit value of the second reference temperature range (step S203: Yes), the circulation control unit 32 increases the rotation speed of the internal fan F through the internal fan drive processing unit 323 (step S204). ), The procedure is returned to end the current process.

  According to this, since the internal air of the product storage 3 circulates in the entire storage, the cooled internal air in the lower part of the product storage 3 changes in a direction of gradually rising, and the product in the product storage 3 The product stored in the upper part of the storage rack 20 can be cooled to an appropriate temperature.

  On the other hand, when the upper temperature is less than the lower limit value of the second reference temperature range (step S203: No, step S205: Yes), the circulation control unit 32 determines the rotation speed of the internal fan F through the internal fan drive processing unit 323. (Step S206), the procedure is returned, and the current process is terminated.

  According to this, since the internal air of the product storage case 3 circulates in the lower part of the storage unit, it is possible to avoid excessive cooling of the product stored in the upper part of the product storage rack 20 of the product storage case 3. Thus, power consumption is reduced.

  When the upper temperature is within the second reference temperature range (step S203: No, step S205: No), the circulation control unit 32 maintains the rotation speed of the internal fan F (step S207), and returns the procedure. To end the current process.

  As described above, in the vending machine according to the embodiment of the present invention, when the control unit 30 detects that the lower temperature detected by the lower thermistor 26 exceeds the upper limit value of the first reference temperature range, the evaporator 6, while the lower temperature falls below the lower limit of the first reference temperature range, the cooling amount by the evaporator 6 is reduced and the upper temperature detected by the upper thermistor 27 is the second reference temperature. When the upper limit of the temperature range is exceeded, the amount of internal air blown by the internal fan F is increased to increase the circulation rate, while when the upper temperature is less than the lower limit of the second reference temperature range, Since the amount of circulating air is reduced by reducing the amount of internal air blown by the fan F, the product that is likely to be paid out at the next sales opportunity (the lowest product) is cooled to the optimum temperature, Goods the quality it is possible to cool to the extent that does not decrease. Therefore, by efficiently cooling the product, it is possible to reduce energy consumption accompanying the cooling of the product.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  For example, in the above-described embodiment, the upper thermistor 27 is disposed at the upper part of the product storage 3, but the upper thermistor 27 is at the top of the products stored in the product storage passage 21. It suffices if the temperature in the vicinity of the product can be detected, and any position can be used as long as it can detect the temperature in the vicinity of the product on the top. Further, since the product at the top has a tendency to gradually move downward with every sale, the upper thermistor 27 may also be arranged in such a manner that it gradually moves downward together with the product at the top.
