[0002]

2. Description of the Related Art In recent years, as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 62-4865, a cooling device for a vending machine is provided with a heating device and a cooling device by the operation of a thermostat so as to save power from the problem of energy saving. In order to stop the device, a power saving method has been adopted in which the in-compartment fan motor can also be stopped in synchronization with this.

Hereinafter, an example of a cooling and heating device for a vending machine will be described with reference to the drawings.

In FIGS. 26 and 27, reference numerals 1 and 2 denote power supply lines, 3 denotes a refrigerator, 4 denotes a heating device, 5 denotes a fan motor in a refrigerator, and 6 denotes a cooling device. Reference numeral 7 denotes a first thermostat for controlling the temperature inside the refrigerator 3, and 8 denotes the heating device 4.
A second thermostat 9 for temperature control inside the refrigerator, and 9 is a thermosynchronous switch. The synchronous switch 9 is a multi-contact type manually operated switch, and a first contact 10 is connected to one of the power supply lines 1 via the first thermostat 7 or the second thermostat 8 and to the synchronous switch. The second contact 11 of 9 is directly connected to the power supply line.

[0005] The operation of the cooling and heating device for a vending machine configured as described above will be described below.

First, when the operation mode is selected and the second contact 11 is closed, the internal fan motor 5 continues to operate regardless of the operation of the first thermostat 7 or the second thermostat 8.

The refrigerator 3 is turned on and off by opening and closing the contacts of the first thermostat 7, and the heating device 4 is turned on and off by opening and closing the contacts of the second thermostat 8.
On the other hand, the thermo-synchronous operation mode is selected, and the operation of the first thermostat 7 or the second thermostat 8 causes the same de-energization as the refrigerator 3 or the heating device 4 to be stopped.

[0008]

However, in the above-mentioned conventional configuration, during energy saving operation such as a thermo-synchronous operation mode, the thermostat 7 synchronizes with the refrigerator 3 to turn on / off the fan motor in the refrigerator. Therefore, when the sales volume is large or in the overload state that lowers the temperature inside the warehouse where the product is put in,
It took a very long time for the internal temperature to reach the predetermined temperature, and there was a problem that a product with a high temperature was sold.

SUMMARY OF THE INVENTION In view of the above problems, the present invention takes a very long time to reach a predetermined temperature in a refrigerator and does not sell high-temperature products. An apparatus is provided.

[0010]

In order to achieve this object, the present invention provides a storage shelf for storing goods in a storage room, a cooling device for cooling the storage shelf below the storage shelf,

And a cooling and heating control unit for controlling the cooling device and the heating device.

With this arrangement, in an overload state in which the temperature in the refrigerator at the time of placing the commodity is lowered by the signal from the arithmetic processing unit, the fan motor in the refrigerator does not perform control, and after the storage shelf reaches the set temperature, Since the air volume of the internal fan motor is controlled, it takes an extremely long time for the internal temperature to reach a predetermined temperature, and energy saving operation can be performed without selling high temperature products.

Further, the temperature detected by the temperature detecting means, which is connected to the temperature detecting means, is set higher in the cooling operation (lower in the heating operation) than the preset internal control temperature and the internal control temperature. It is provided with a configuration comprising an arithmetic processing section for comparing with a fan motor control temperature and outputting a signal.

With this arrangement, in an overload state in which the temperature in the refrigerator in which the articles are put is lowered by the signal from the arithmetic processing unit, the fan motor in the refrigerator does not perform the control, and after the storage shelf reaches the set temperature, In order to control the air flow rate of the fan motor in the refrigerator, it takes a very long time for the temperature in the refrigerator to reach a predetermined temperature, so that high-temperature products are not sold, and the fan motor control temperature can be arbitrarily set.

With this configuration, in an overload state in which the temperature in the refrigerator in which the product is placed is reduced by the signal from the arithmetic processing unit, the fan motor in the refrigerator is not controlled, and the temperature of the storage shelf is small. Since the stable state is accurately determined and the air volume of the fan motor in the refrigerator is controlled, it takes a very long time for the temperature in the refrigerator to reach a predetermined temperature, and the number of times of selling high temperature products is further reduced. Energy saving operation can be performed without disturbing customers.

When the temperature detected by the cooling temperature detecting means is lower than the fan motor control temperature based on a signal from the arithmetic processing unit, the air volume of the fan motor in the refrigerator is controlled by intermittent operation, ON / OFF operation and the like. If the temperature detected by the temperature detecting means exceeds the fan motor control temperature, the control is stopped (intermittent operation if the temperature detected by the temperature detecting means exceeds the fan motor control temperature during heating). (The air flow of the fan motor in the refrigerator is controlled by ON / OFF operation or the like, and the control is stopped when the temperature detected by the temperature detecting means falls below the fan motor control temperature.)
