[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0019] Example
[0020] This embodiment provides a novel automatic vending machine freezer door, specifically designed for automatic vending machines that require seasoning packets. It divides the traditional freezer door into two parts: an inner door and an outer door, to facilitate the dispensing of seasoning packets by the seasoning packet dispenser.
[0021] For details, please refer to Figure 1 , Figure 2 It includes an inner door 1 and an outer door 2 that is rotatably mounted on the front side of the inner door 1. One side of the outer door 2 is connected to the inner door 1 via a door hinge 3. The other side of the outer door 2 is equipped with an upper door lock 4 and a lower door lock 5, respectively. The outer door 2 is locked to the inner door 1 by the upper door lock 4 and the lower door lock 5. When the seasoning packet dispenser dispenses the seasoning packet, he can open the outer door 2 by unlocking the upper door lock 4 and the lower door lock 5 to dispense the seasoning packet without having to open the entire freezer door. This avoids the increase in electricity costs caused by the loss of cold air when dispensing the seasoning packet, while ensuring the preservation quality of the boxed meals.
[0022] Furthermore, the outer door 2 is equipped with a touch panel 6, a barcode scanner 7, and an advertising screen 8. In use, users can purchase meals via the touch panel 6 and pay via the barcode scanner 7. The advertising screen 8 displays the boxed meals in the freezer.
[0023] Furthermore, a sealing and heat-insulating strip is provided on the inner edge of the outer door 2 to achieve a sealed connection with the inner door and prevent the leakage of cold air from the vending machine freezer.
[0024] Furthermore, the inner door 1 has a front-opening seasoning packet dispensing chamber 11, in which several seasoning packet dispensing devices 9 are arranged in parallel. Each seasoning packet dispensing device 9 includes a vertically arranged synchronous belt 91, several hooks 92 spaced apart on the synchronous belt 91, and a drive motor 93 that drives the synchronous belt 91. The bottom of the seasoning packet dispensing chamber 11 is provided with a connected centralized funnel 12, and the outer door 2 is provided with a seasoning packet outlet 21 that communicates with the bottom of the centralized funnel 12. When dispensing seasoning packets, simply hang each seasoning packet on the hook 92 of the seasoning packet dispensing device 9. When the seasoning packets are dispensed, the drive motor 93 drives the synchronous belt 91 to rotate downwards, causing several hooks 92 to flip sequentially to the other side of the synchronous belt 91. During the flipping process of the hooks 92, the seasoning packets hanging on them will fall from the hooks 92 through the collection funnel 12. At this time, the seasoning packets can be retrieved through the seasoning packet outlet 21 on the outer door 2.
[0025] The centralized funnel 12 has one side inclined downwards and the other side vertically downwards.
[0026] Furthermore, a camera 10 is installed at the top of the inner door 1 to monitor the user's meal purchase.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
