  However, when the value of the temperature sensor installed in the cabinet in the conventional configuration is displayed on the display of the outer door, the air temperature in the cabinet ≒ product temperature ≒ temperature sensor temperature in the standby state (when the inner door is closed) However, when the inner door is opened and the product is replenished, the outside air enters the cabinet, so that the temperature inside the cabinet is equal to the temperature sensor> the product temperature. Therefore, there is a problem that accurate temperature cannot be displayed because it is necessary to make a temporary work such as temporarily not displaying the actual temperature so as not to give the customer anxiety by displaying a temperature higher than the actual product temperature. It was.

  In addition, when a heat capacity is attached to the temperature sensor and a temperature close to the product temperature (pseudo product temperature) is displayed, the value of the pseudo product temperature is displayed at the time of installation or when the product is empty when there is no product. In other words, the display temperature is less likely to be lower than the actual internal temperature (in the air).

  The present invention solves the above-mentioned conventional problems, and automatically displays the temperature required by the customer according to the conditions such as when installing, when the product is empty initial, when waiting for actual operation, and when replenishing the product. It is an object to provide an internal temperature display device for a vending machine capable of performing the above.

  In order to solve the above-described conventional problems, the internal temperature display device of the vending machine according to the present invention includes a product to be sold, a chamber covered with a heat insulating material for storing the product, and a warehouse for replenishing the product. Inner door provided inside, product storage for storing and unloading products, outer door provided on the vending machine exterior, internal fan for circulating in the storage, and cooling the interior Cooler and refrigerator, a display for displaying the internal temperature, a temperature sensor A for detecting the internal air temperature, a load with a heat capacity substantially equal to the product, and the temperature of the load Temperature sensor B for detecting the temperature, setting means for setting the actual operation start temperature, and an arithmetic processing unit for comparing and calculating the value set by the setting means and the value of the temperature sensor. If the internal temperature is higher than the actual operation start temperature, the product is empty during installation. Initial time of the decision, to display the temperature in Kuranaiki.

  In addition, after the inside of the refrigerator is cooled and reaches the set actual operating temperature, the display is switched to the pseudo product temperature corresponding to the product temperature. As a result, the internal air temperature can be displayed at the initial stage, the product temperature can be displayed at the time of standby for actual operation, and the product can be replenished, and the temperature required by the customer can always be displayed automatically.

  The internal temperature display device of the vending machine according to the present invention has an arithmetic processing unit for comparing and calculating the values of the temperature sensors A and B. Display the value. As a result, during continuous cooling operation (for example, initial pull-down) from a high temperature in the refrigerator to a low temperature (product storage temperature), the temperature sensor A (in-chamber detection) is detected from temperature sensor A (low heat capacity) <B (high heat capacity). When the product is replenished by opening the inner door, the outside air invades, so the air temperature in the cabinet rises, and the temperature sensor A (low heat capacity)> B (high heat capacity) is set to the temperature sensor B (pseudo product temperature). In standby mode where the storage temperature is controlled to be almost constant, temperature sensor A (small heat capacity) ≒ B (large heat capacity), so A or B can be displayed. Normally, the internal temperature (air) At the time of product replenishment (inner door opening) where the product temperature is expected to rise the most during actual operation, the essential product temperature can be displayed automatically.

  In addition, the internal temperature display device of the vending machine according to the present invention sets power detection means for detecting that the power supply to the main body is turned OFF → ON, and the time from power-on to the start of actual operation. Setting means, a timer for counting the time since the power is turned on, and an arithmetic processing unit for comparing and calculating the value set by the setting means and the timer value. When the power is turned on, it is determined that the initial pull-down at the time of installation (no product) or the like, and the inside air temperature is displayed for the set time. Thereafter, the product temperature is switched to the product temperature (pseudo product temperature).

  With this, the temperature in the cabinet can be displayed automatically when installing or when the product is empty, and the product temperature can be displayed automatically when waiting for actual operation or when refilling the product. .

  The internal temperature display device of the vending machine of the present invention automatically displays the temperature required by the customer according to the conditions, such as when installing, when the product is empty initial, when waiting for actual operation, when replenishing the product. I can do it.

In order to display the temperature, if the internal temperature is higher than the set actual operation start temperature, it is determined that the product is at the time of installation or when the product is empty initial, and the internal air temperature is displayed.

  In addition, after the inside of the refrigerator is cooled and reaches the set actual operating temperature, the display is switched to the pseudo product temperature corresponding to the product temperature. As a result, the internal air temperature can be displayed at the initial stage, the product temperature can be displayed at the time of standby for actual operation, and the product can be replenished, and the temperature required by the customer can always be displayed automatically.

  The second invention has an arithmetic processing unit for comparing and calculating the values of the temperature sensors A and B, and compares the temperature sensors A and B to display a sensor value having a low temperature.

  As a result, during continuous cooling operation (for example, initial pull-down) from a high temperature in the refrigerator to a low temperature (product storage temperature), the temperature sensor A (in-chamber detection) is detected from temperature sensor A (low heat capacity) <B (high heat capacity). When the product is replenished by opening the inner door, the outside air invades, so the air temperature in the cabinet rises, and the temperature sensor A (low heat capacity)> B (high heat capacity) is set to the temperature sensor B (pseudo product temperature). In standby mode where the storage temperature is controlled to be almost constant, temperature sensor A (small heat capacity) ≒ B (large heat capacity), so A or B can be displayed. Normally, the internal temperature (air) At the time of product replenishment (inner door opening) where the product temperature is expected to rise the most during actual operation, the essential product temperature can be displayed automatically.

  In the third invention, since the temperature detected by the internal temperature sensor A is displayed for a certain period of time after the power is turned on, the time set when the power is turned on is determined to be the initial pull-down time such as installation (no product). Only the inside air temperature is displayed, and then the product temperature (pseudo product temperature) is switched.

  With this, the temperature in the cabinet can be displayed automatically when installing or when the product is empty, and the product temperature can be displayed automatically when waiting for actual operation or when refilling the product. .
