Therefore, the vending machine is generally large in size, high in equipment cost, capable of meeting certain requirements for human flow and provided with a certain putting arrangement threshold.

At present, a plurality of bagged food, boxed food, drink and the like marked with prices are usually placed in guest rooms of hotels and hotels for customers to live in and consume. If the customers consume the food and the drinks during the check-in period, when the customers leave the house, the house settlement can be finished after the waiters check the rooms of the customers, and the process is complicated and wastes time. Although the vending machine can be arranged in public spaces of hotels and hotels, customers still need to leave the rooms to buy the vending machine, and the vending machine is still not humanized. In addition, for commodities such as family planning articles and privacy articles, the vending machine placed in the public space is not favorable for protecting the privacy of customers and selling commodities. In addition, some humanized guest rooms are also provided with small refrigerators for customers to use. The customers can refrigerate food and drinks sold in guest rooms and can refrigerate food and drinks carried by the customers. However, on one hand, the customers need to refrigerate the commodities by themselves, so that the customers cannot be in a very urgent need to be relieved; on the other hand, since the waiters still need to count and settle accounts, and the sold goods in the refrigerator and the articles carried by the customers are difficult to distinguish, the process is complicated and the time is wasted; therefore, most of the small refrigerators arranged in the guest rooms are vacant, and the utilization rate is low. Therefore, there is a need for a small and low cost refrigerator that can not only automatically sell refrigerated goods, but also be used for self-service refrigeration by customers.
