[0039] In order to more clearly illustrate the technical solution of the utility model, a preferred embodiment is provided below. Figures 1 to 8 A multi-grid vending machine includes a cabinet 1, a control device 2, a refrigeration device 3 and a plurality of storage devices 4, wherein:

[0040] A temperature control chamber 11 is provided in the cabinet 1, and each storage device 4 is orderly arranged in the temperature control chamber 11 and fixedly connected to the cabinet 1;

[0041] The storage device 4 includes a storage box 41 and a heating mechanism 42; a meal taking door 43 is provided on the front side of the storage box 41, and the meal taking door 43 is movably connected to the storage box 41, preferably hinged, and a locking structure 44 for locking the meal taking door 43 is installed on the storage box 41; the heating mechanism 42 is installed on the storage box 41; a cold air hole 45 connected to the inner cavity of the storage box 41 is opened, a one-way valve 46 is arranged in the cold air hole 45, and an exhaust fan 47 for passing the cold air of the temperature control cavity 11 into the one-way valve 46 is arranged outside the one-way valve 46;

[0042] The refrigeration device 3 is installed inside the cabinet 1 and is used to control the temperature of the temperature control chamber 11;

[0043] The control device 2 is installed on the cabinet 1 and is electrically connected to the refrigeration device 3 and each storage device 4 .

[0044] Compared with the prior art, the multi-grid vending machine involved in the utility model is different in that: the present application sets a plurality of independent storage devices 4 in the vending machine, and each storage box 41 can be used to place food; during the storage process, the refrigeration device 3 controls the temperature control chamber 11 to be at a temperature suitable for preserving food, and after the exhaust fan 47 is started, the cold air extracted can pass through the one-way valve 46 and enter the storage box 41, so that the inside of the storage box 41 is kept at a low temperature, so as to preserve the food. When the user places an order, the exhaust fan 47 on the storage device 4 containing the corresponding food is closed, and then the one-way valve 46 is in a closed state, so as to control the inner cavity of the storage box 41 to be isolated from the temperature control chamber 11, and then the heating mechanism 42 is used to heat the food. After the heating is completed, the locking structure 44 releases the lock on the food retrieval door 43, and the user can take out the food by himself. By adopting the design of the present application, the storage devices 4 in the vending machine are independent of each other, and the heating and cooling processes thereof do not affect each other. Thus, there is no order in which the food is heated inside the vending machine. After the user places an order, he only needs to wait for the food he has selected to be heated, thereby greatly shortening the user's waiting time and improving the user's experience.

[0045] In this embodiment, the one-way valve 46 includes a baffle 461, a spring 462 and a sleeve 463 with an opening at one end. The sleeve 463 is sealed and connected to the storage box 41. Its open end is close to the exhaust fan 47 and is provided with a baffle ring 464. An air vent 466 is provided in the middle of the sleeve 463. The air vent 466 is located in the storage box 41. The baffle 461 is slidably connected in the sleeve 463. The two ends of the spring 462 are fixedly connected to the baffle 461 and the sleeve 463 respectively, and the baffle 461 is in contact with the baffle ring 464. In actual application, the wind force driven by the start-up of the exhaust fan 47 can push the baffle 461, so that the baffle 461 moves away from the baffle ring 464 until the air vent 466 is exposed on the front side of the baffle 461. At this time, the cold air in the temperature control chamber 11 can enter the storage box 41 along the air vent 466, so as to reduce the temperature in the storage box 41, thereby achieving the effect of refrigeration and preservation; when the heating mechanism 42 is started, the exhaust fan 47 is closed accordingly, and the baffle 461 keeps in contact with the baffle ring 464 under the action of the spring 462. At this time, the cold air in the temperature control chamber 11 cannot enter the storage box 41, thereby avoiding interference with the heating of the food.

[0046] Preferably, a slide bar 467 is provided on the baffle 461, a slide hole is provided at the end of the sleeve 463, and the slide bar 467 is slidably connected in the slide hole; the spring 462 is sleeved outside the slide bar 467. With this design, the baffle 461 can slide more stably in the sleeve 463, thereby improving the control stability of the one-way valve 46.

[0047] Preferably, the baffle 461 is made of a heat-insulating material. With this design, the influence of the cold air in the temperature-control chamber 11 on the internal temperature of the storage box 41 can be reduced to the greatest extent.

[0048] Preferably, a temperature sensor is provided in the storage box 41. When the temperature sensor detects that the temperature in the storage box 41 reaches a temperature suitable for preserving food, the exhaust fan 47 will be turned off to reduce energy consumption.

[0049] In this embodiment, a heat dissipation cavity 12 is further provided in the cabinet 1, and the heat dissipation cavity 12 is not communicated with the temperature control cavity 11; an air outlet 48 is provided on the storage box 41, and the air outlet 48 is communicated with the heat dissipation cavity 12. In actual application, cold air is input from the cold air hole 45, and high-temperature air can be discharged from the air outlet 48, so that the storage box 41 can reach a temperature suitable for storing food at the fastest speed, thereby reducing the energy consumption of the vending machine.

[0050] Preferably, the air outlet 48 is also provided with a conduction mechanism consisting of a one-way valve 46 and an exhaust fan 47. In this way, the storage box 41 can avoid being disturbed by the high-temperature gas in the heat dissipation cavity 12 when the food is refrigerated and kept fresh.

[0051] In this embodiment, a heat-insulating layer 49 is disposed on the outside of the storage box 41 and the inner wall of the temperature-control chamber 11. This design can improve the heat-insulating effect of the storage box 41 and the temperature-control chamber 11. Preferably, the heat-insulating layer 49 is made of ceramic material.

[0052] In this embodiment, the heating mechanism 42 includes a waveguide tube 421, a magnetron 422 and a heat dissipation fan 423; the waveguide tube 421 is installed on the storage box 41, and its inner cavity is connected to the inner cavity of the storage box 41, the magnetron 422 is installed on the waveguide tube 421, its microwave transmitting head is arranged in the waveguide tube 421, and the heat dissipation fan 423 is installed on the magnetron 422. The heating mechanism 42 is also arranged in the heat dissipation cavity 12. In actual application, the microwave transmitting head of the magnetron 422 emits microwaves into the waveguide tube 421, and the microwaves enter the storage box 41 under the guidance of the waveguide tube 421, and continuously travel inside the food under the action of refraction, so that the food generates "internal friction heat" and heats up. Compared with other heating methods, the microwave heating method has high heating efficiency and low energy consumption, and the wall surface of the storage box 41 is not affected by microwaves, which can prevent users from being scalded when taking food, and has strong safety.

[0053] In this embodiment, the locking structure 44 includes an electric lock, and a lock hole is provided on the meal-taking door 43, and the mobile end of the electric lock is inserted into the lock hole. In actual application, after the staff who are making up the meal put the meal into the storage box 41, the meal-taking door 43 and the storage box 41 are locked by the cooperation of the electric lock and the lock piece. When the user takes the meal, the control system of the vending machine will drive the mobile end of the corresponding electric lock to exit the lock hole, so that the user can open the meal-taking door 43 to take the meal by himself.

[0054] In this embodiment, the control device 2 includes an electric control box 21 and a control screen 22. The electric control box 21 is installed inside the cabinet 1, and the control screen 22 is installed on the outer wall of the cabinet 1 and is electrically connected to the electric control box 21. In actual application, the control screen 22 is used to display information about optional meals for users to select and order meals.

[0055] As another preferred solution, the control device 2 may also only include the electric control box 21, and each storage device 4 is provided with an independent controller, and each controller is electrically connected to the electric control box 21. With this design, each storage device 4 can be independently controlled, thereby improving the efficiency of users taking meals.

[0056] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
