Description

[Detailed description of the invention] This invention relates to a vending machine, and regardless of whether the products stored and sold inside the machine require cooling or heating, the products can be sold using one machine. This is to provide a vending machine that makes it possible to

In recent years, there has been a remarkable diversification of products sold by vending machines, and there are many foods and drinks that require cooling in the summer and heating in the winter.

In view of this point, the present invention provides a vending machine that enables selective cooling and heating and has a simple configuration.

An embodiment of the present invention will be described below with reference to the drawings. 1 is a housing-like heat insulating wall with one side open, 2 is a door provided in the open part of the heat insulating wall 1 so that it can be opened and closed freely, and 3 is a wall surrounded by the heat insulating wall 1. storage/delivery; 4 is an evaporator of a cooling device installed at the bottom of the storage 3;
Reference numeral 5 denotes an air passage plate which is placed over the evaporator 4 and has a circulating air inlet 6 button at one end and a discharge lower button at the other end; 9 is a heating element of a heating device such as a heating wire installed near the discharge lower; 10 is a heating element for circulating air in the storage 3 from the discharge lower through the suction port 6 and the discharge port; 11 is a storage/unloading mechanism provided in the center of the storage 3 to store sales items and unloads the items based on a signal from a coin counting device (not shown); 12 is a storage/unloading mechanism 11; the bottom of the door 2
An ejection path 14 is provided below the storage 3, and is connected to a condenser 15, a blower 16 for cooling the condenser, and a condenser cooling blower 16. This is a machine room with a machine 1T installed.

As shown in FIG. 3, the electric circuit is such that a circulation blower 8 is connected in parallel to a power source 18, and a heating circuit B and a cooling circuit C are connected in parallel to the power source 18, as selected by a changeover switch 19. .

The heating circuit B is formed by a series circuit of a thermostat 20, a heating element 9, an overtemperature rise prevention switch 21, and a temperature fuse 22, and these are provided in the storage 3.

Further, the cooling circuit C is formed by connecting in series a parallel circuit of a condenser cooling blower 16 and a compressor 17 to a thermostat 23, and the thermostat 23 is provided in the storage 3, and the condenser cooling blower 16 and compressor 17 are connected in series. is provided in the machine room 14.

However, the above circuit does not show the electrical circuits of the coin counting device button and the ejecting mechanism.

Based on the above configuration, the operation of the vending machine of the present invention will be explained. During cooling operation, the cooling circuit C is energized, and the compressor 17 and condenser cooling blower 16 in the machine room 14 and the evaporator in the storage 3 By operating a cooling cycle consisting of 4 components,
The evaporator 4 is pressed to provide a cooling effect.

At this time, inside the storage 3, air is discharged from the discharge lower by the circulation blower 8 as shown by the arrow, circulated through the storage 3, sucked in from the suction port 6, cooled by the evaporator 4, and then reused. A circulating air path 10 is formed that discharges air from the outlet T.

As a result of the above action, the sales products stored in the storage/unloading mechanism 11 and waiting to be transported are cooled, and when the customer inserts a coin, the storage/unloading mechanism 11 is operated, and the cooled sales products are transported through the transport path 12. and is supplied to the outlet 13.

During heating operation, heating circuit B is energized and storage compartment 3
Inside, as shown by the arrow, a circulating air passage 10 is formed in which internal air is sucked in from the intake port 6 by the circulating blower 8, heated by the heating element 9, and then discharged from the discharge lower.

As a result of the above action, the sales products stored in the storage/unloading mechanism 11 and waiting to be taken out are warmed, and when the customer inserts a coin, the storage/unloading mechanism 11 is operated, and the heated sales items are transferred via the unloading path 12. It is supplied to the outlet 13.

Therefore, the heating element 9 during the heating operation is not limited to being provided in the vicinity of the discharge lower of the air path plate 5 shown in FIGS. 1 and 2, but, for example, as shown in FIG. It is clear that the heating element 9' can also be provided at the position shown in front of the heating element 9'.

The thermostat 20 and the thermostat 23 are used to control the temperature inside the storage compartment 3 to an arbitrary constant temperature during cooling operation and heating operation, and the overtemperature rise prevention switch 21'I? The temperature fuse 22 is a device that detects an abnormal temperature rise in the storage compartment 3 that occurs during heating operation, and protects safety by preventing this.
The second hole 12a is for improving the circulation of circulating air.

As described above, the present invention provides an air passage plate 5 with an inlet 6 at one end and a discharge lower at the other end in the storage 3 in which the storage and unloading mechanism 11 for sale products is stored, and below the storage and unloading mechanism 11. A circulation blower 8 is provided in the air path board 5 to form an air path 10 for circulating the air in the storage 3, and an evaporator 4 of the cooling device is provided in the air path board 5 in the air path 10. At the same time, a heating element 9 of the heating device is provided near the suction port 6 or the discharge port I to selectively enable cooling operation and heating operation. By sharing the air circulation blower 8, the cost of parts is reduced, and the configuration is simplified to improve assembly workability.Also, the outlet T of the air passage plate 5 is provided near the bottom of the product storage/unloading mechanism 11. The air discharged from the discharge lower strongly cools or heats the product just before being carried out, making it possible to effectively cool or heat the product. This is a device that has excellent practical effects, such as making it possible to choose between cooling and heating depending on the product being sold.
