Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine which can maintain the temperature in a storage zone at a temperature suitable for storing commodities even when the commodities in the sales zone are being heated.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. 2000-57431 and Japanese Unexamined Patent Publication No.
1855 JP, JP 2000-113301 A,
There are those described in JP-A-2000-113303 and the like. Hereinafter, this vending machine will be described.

[0003] In the insulation box, which is the main body of the vending machine,
A plurality of product storage rooms are provided. The product storage room, when classified by temperature, a product storage room dedicated to cooling,
There is a product storage room dedicated to heating and a product storage room for switching heating and cooling. When classified by zone division, the product storage room has a zone-divided product storage room divided into a storage zone and a sales zone, and a zone-undivided product not divided into a storage zone and a sales zone. There is a storage room.

[0004] The products in the cooling-only product storage room are constantly cooled. Also, the products in the heating-dedicated product storage room are always heated. Further, the product in the product storage room for switching between heating and cooling is heated or cooled by switching between the heating unit and the cooling unit.

In the zone divided product storage room, the inside of the sales zone is heated or cooled.
The inside of the storage zone is kept at normal temperature. Further, the whole of the zone-undivided product storage room is heated or cooled.

[0006] When the selling operation is performed, the goods in the goods storage room or the sales zone are transferred to the take-out port via the chute and are sold. When the number of items in the sales zone decreases, the items in the storage zone are supplied into the sales zone. Further, when the number of commodities in the storage zone is reduced, the commodities are supplied and supplied into the storage zone.
Furthermore, when there are few products in the product storage room,
The product is supplied and supplied into the product storage room.

[0007] The vending machine is configured by combining the various commodity storage rooms described above. As an example of the combination of the product storage rooms, one cooling-dedicated zone non-divided product storage room, one heating / cooling switching zone non-divided product storage room, and two heating only or heating only. There is one configured from a zone-divided product storage room for cooling switching.

[0008]

However, in the above-mentioned conventional vending machine, the zoned product storage room is simply divided into a storage zone and a sales zone. For this reason, when the conventional vending machine heats the inside of the sales zone by the heating means, the warmed air in the sales zone enters the storage zone, and the temperature in the storage zone becomes higher than the temperature in the sales zone. It is almost equal to the temperature. The temperature in this sales zone is suitable for selling goods, but is higher than the temperature suitable for storing goods, and is not suitable for storing goods.

In a vending machine installed in a place where sales of commodities are not favorable, if the temperature in the storage zone is higher than a temperature suitable for storing commodities, it is necessary to wait until the commodities are sold. In some cases, it may be necessary to replace the product.

[0010] In particular, when the storage zone is located at the upper stage of the product storage room and the sales zone is located at the lower stage of the product storage room, the warmed air in the sales zone rides on the rising airflow. The problem is even more pronounced because it is easy to get into the storage zone.
