It is constructed and operated in a specific orientation and is therefore not to be construed as limiting the invention.

[0026] Embodiments of the present invention provide a vending machine, as shown in FIG. 1, including a vending machine body 100 having a light box 101 and an advertising screen 102 for illumination and advertising. The kiosk main body 100 is provided with a control unit 1, a freezing unit 2, a heating unit 3, a conveying unit 4, a payment unit 5, and a pickup unit 6. Wherein, the control unit 1 can control the operation of the vending machine; the freezing unit 2 can store the food and freeze the stored food; the heating unit 3 can receive the food and heat the received food; and the conveying unit 4 can transfer the food from the freezing unit 2 to the heating unit 3; the payment unit 5 is capable of the user selecting the food and paying; the picking unit 6 is capable of taking and taking out the food from the vending machine main body 100. The heating unit 3 and the freezing unit 2 are thermally isolated by the isolation module 7, and in particular, the isolation module 7 is a polyurethane insulation panel. The freezing unit 2, the heating unit 3, the conveying unit 4, the payment unit 5, and the pickup unit 6 are all in communication connection with the control unit 1.

[0027] Compared with the prior art, the vending machine provided by the present invention can prevent the temperature fluctuation of the freezing unit 2 from affecting the temperature fluctuation of the heating unit 3 by setting the freezing and heating isolation of the food and separately, thereby improving the food's safe storage period. The isolation module 7 can thermally isolate the freezing unit 2 from the heating unit 3, reduce heat transfer between the two, improve the freezing capacity of the freezing unit 2, and thereby improve the safe storage period of the food. Referring to FIG. 1, the freezing unit 2 includes a freezing chamber 21 and a compressor 22 that compresses refrigerant to control the temperature in the freezing chamber 21 to 18 C. or lower. The freezing unit 2 also includes a condenser, an evaporator, an air deflector, etc., which are common devices in compression refrigeration, which are not shown in the drawings for the sake of simplicity. The temperature of the freezing chamber 21 is controlled to 18 C. or below, and the original quality of the food is preserved at a low temperature such that, for example, water, juice, etc. in the food tissue are not lost, and microorganisms are effectively inhibited without any preservatives and additives. At the same time, the food nutrition is preserved to the utmost extent, and the food has the advantages of deliciousness, convenience, health, hygiene, nutrition and benefits, and the food is safe.

[0028] Referring to FIG. 1, an ozone sterilization module 23 is further disposed in the freezing unit 2 to sterilize and disinfect the food in the freezing unit 2 by using ozone to ensure the safety of the food. Ozone sterilization is rapid and efficient, and the oxides produced during the sterilization process are non-toxic and tasteless, and will not cause secondary pollution. Referring to FIG. 1, the heating unit 3 includes a closed heating chamber 31, a magnetron 32 for heating, and a cooling module for cooling the magnetron 32 (The structure and operation of a cooling module for magnetron cooling are well-known to those of ordinary skill in the art, and for the sake of simplicity, not shown in the figure). There are two magnetrons 32, which are disposed at upper and lower positions of the heating chamber 31. Microwaves can be generated by the magnetron 32 to microwave the food located in the heater.

[0029] Specifically, there are two magnetrons 32, and two magnetrons 32 are disposed at the top and bottom of the heating chamber 31. The two magnetrons 32 disposed above and below enable the temperature inside the heating chamber 31 to rise rapidly, so that the food in the heating chamber 31 can be quickly heated. The heating unit 3 has the advantages of uniform heating, high speed, selective heating, strong heat penetration capability, etc., which can shorten the heating time, improve the food manufacturing efficiency, and improve the product quality.

[0030] Water has a higher specific heat capacity and can absorb more heat. Therefore, the cooling module is provided as a water-cooling module, and the magnetron 32 is quickly and effectively cooled by water cooling, and the cooling efficiency is high. In other embodiments, the cooling module can also be an air cooled module or any other module that can effect cooling of the magnetron 32. Referring to FIG. 2, the freezing unit 2 also has a plurality of cargo lanes 103, each of which is capable of receiving a plurality of food items. The receiving surface of the cargo lane 103 is provided with a first conveyor belt 104. When it is necessary to purchase the food at a certain cargo lane 103, the first conveyor belt 104 operates to transport the food product toward the opening of the cargo lane 103 until the food product near the opening falls onto the conveying unit 4.

[0031] As shown in FIGS. 1 and 2, the conveying unit 4 includes a transport table 41, a first drive mechanism 42 and a first push mechanism 43, the transport table 41 is capable of receiving food, and the first drive mechanism 42 is configured to be capable of driving the position of the transport table 41. In the transfer, the first pushing mechanism 43 can push the food on the transfer table 41 through door 63 into the pickup unit 6, which is capable of lifting the food vertically into heating unit 3. The food is taken up by the transport table 41, and when the food is pushed into the heating unit 3 by the first pushing mechanism 43, the food on the transport table 41 is only subjected to the gravity and the support force given by the transport table 41, and the food is not affected by the external force. No deformation occurs to keep the shape of the food intact and beautiful. The first pushing mechanism 43 may be a linear motor, a cylinder assembly or a screw assembly, or the like.

[0032] The first driving mechanism 42 is a two-axis linkage mechanism, and the first driving mechanism 42 can drive the up and down and left and right movements of the transport table 41. The receiving surface of the transport table 41 is provided with a second conveyor belt 44. When the transport table 41 is moved to the heating unit 3, the second conveyor belt 44 operates to transport the food toward the heating unit 3, reducing the force of the first pushing mechanism 43 that was pushing the food to protect the shape of the food.

[0033] Referring to FIG. 1, in the present embodiment, the payment unit 5 includes an operation screen 51 and a cash collection port 52.
