[0068] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0069] See also Figures 1 to 12 as stated;

[0070] The vending refrigerator of this embodiment includes:

[0071] The main body 1 is a box structure, the upper part of the main body 1 is hollow, and the hollow structure forms a accommodating cavity for the lunch box 6;

[0072] A refrigeration unit 2, which is integrated in the lower part of the main body 1, and the refrigeration unit 2 is connected to the accommodating cavity to cool down and preserve the lunch box 6 placed in the accommodating cavity;

[0073] A heating microwave oven 3, which is integrated into the lower part of the main body 1;

[0074] The main body 1 has a conveying assembly for placing and conveying the lunch box 6;

[0075] The conveying components respectively include a first conveying component for conveying the lunch box 6 in a vertical direction, and a second conveying component 5 for conveying the lunch box 6 in a horizontal direction;

[0076] The second conveying assembly 5 is arranged at the lower end of the first conveying assembly and receives the lunch box 6 delivered thereto by the first conveying assembly;

[0077] The interior of the heating microwave oven 3 is formed as a heating cavity, and the heating microwave oven 3 has a meal-in end cover 302 opened toward the inside of the main body 1, and a meal-out end cover 302 opened toward the outside of the main body 1;

[0078] The output end of the second conveying assembly 5 is close to the dining end cover 302 of the heating microwave oven 3 and conveys the lunch box 6 into the heating cavity.

[0079] Specifically, this embodiment discloses an automatic vending refrigerator applicable to any place. The main technical difference between the vending refrigerator and other similar vending machines is that the vending refrigerator is mainly used to vend lunch boxes 6. Due to the particularity of the lunch boxes 6, the lunch boxes 6 need to be kept fresh at low temperatures when not eaten. Therefore, a refrigeration unit 2 is integrated at the lower part of the main body 1. The refrigeration unit 2 is similar to the structure inside the refrigerator in the prior art. Both are connected to the main body 1 to provide low-temperature gas, and the temperature in the accommodating cavity of the main body 1 is reduced by heat exchange to achieve the purpose of low-temperature preservation. In addition, the lunch boxes 6 need to be heated when eaten. Therefore, a heating microwave oven 3 capable of heating the lunch boxes 6 is integrated at the lower part of the main body 1, and a conveying assembly capable of conveying the lunch boxes 6 to the heating microwave oven 3 is also provided, wherein the conveying assembly should be designed as at least two groups in principle, that is, the types of food inside the lunch boxes 6 transmitted by each group of conveying assemblies are different, and the user selects the dishes by himself and controls the movement of the corresponding conveying assembly. Each group of conveying components has a first conveying component and a second conveying component 5, wherein the first conveying component 5 not only has the function of conveying the lunch box 6, but also provides a placement and storage space for the lunch box 6 when it is not sold. When it needs to be transported, the first conveying component conveys the lunch box 6 to the second conveying component 5, and then the second conveying component 5 conveys the received lunch box 6 to the heating microwave oven 3 for heating, and finally the user takes the lunch box from the heating microwave oven 3. The whole device combines the automatic vending technology with the refrigerator in the prior art, and integrates the heating microwave oven 3 that can heat the lunch box 6 at any time, so that it has good timeliness, and the preservation and consumption of food meet the user's requirements.

[0080] Preferably, in this embodiment, the first transmission assembly includes an upper transmission shaft 402 fixed to the upper end of the main body 1 and extending in the horizontal direction, and a lower transmission shaft 405 fixed to the lower end of the main body 1 and extending in the horizontal direction;

[0081] A transmission chain 403 is connected between the upper transmission shaft 402 and the lower transmission shaft 405;

[0082] A driving motor 401 is installed at the end of the upper transmission shaft 402 and / or the lower transmission shaft 405, and the driving motor 401 drives the upper transmission shaft 402 and / or the lower transmission shaft 405 to rotate to drive the transmission chain 403 to transmit along the vertical direction;

[0083] The driving motor 401 is a stepping motor;

[0084] A plurality of lunch box racks are arranged at intervals along the vertical direction of the transmission chain 403 near the second conveying assembly 5, and the lunch boxes 6 are placed on the lunch box racks;

[0085] The first conveying assembly is driven by the driving motor 401 to sequentially convey the lunch boxes 6 placed on the lunch box storage rack to the second conveying assembly 5 .

[0086] The second conveying assembly 5 is a conveyor belt horizontally arranged at the lower part of the main body 1;

[0087] Each set of lunch box storage racks has two storage plates 404 that are separated from each other, and both ends of the lunch box 6 are supported by the storage plates 404;

[0088] The width of the conveyor belt is not greater than the gap between the two storage plates 404;

[0089] When the driving motor 401 drives the conveying assembly to move, the lunch box rack moves downward, and the storage plate 404 passes along the side of the transmission belt, and the lunch box 6 placed on the lunch box rack is transferred to the conveyor belt;

[0090] The conveyor belt is driven by a motor;

[0091] The conveyor belt transports the lunch box 6 placed thereon to the heating microwave oven 3 in a horizontal direction for heating.

[0092] The structure and working principle of the first conveying component and the second conveying component 5 are introduced in detail here. First of all, the first function of the first conveying component is to store the lunch box 6, and the second function is to transport the lunch box 6 once in the vertical direction and transport the lunch box 6 to the second conveying component 5. The first conveying component disclosed in this embodiment uses the driving motor 401 as the main driving component. At the same time, the driving motor 401 uses a stepping motor, which has a good feedback effect and runs more accurately and flexibly. In addition, the front side of the transmission chain 403 has separated storage plates 404, and the two storage plates 404 form a lunch box storage rack for the lunch box 6. The lunch box 6 is placed on the corresponding lunch box storage rack in advance, and the storage plates 404 are used to support the two ends of the lunch box 6. At the same time, the middle position of the lunch box 6 is exposed to the outside to facilitate the subsequent second conveying component 5 to receive the lunch box 6. Driven by the driving motor 401, the first conveying assembly moves continuously to convey the lunch box 6 to the second conveying assembly 5. At this time, the first conveying assembly stops working, and the second conveying assembly 5 starts to convey. The second conveying assembly 5 uses a simple conveyor belt as a conveying component, and its width is not greater than the distance between the two storage plates. The purpose is to ensure that the storage plates 404 can pass smoothly from both sides of the conveyor belt, and to ensure that the second conveying assembly 5 can smoothly receive the lunch box so that it can continue to be conveyed in the horizontal direction. The second conveying assembly 5 is also driven by the motor to convey the lunch box to the heating microwave oven 3 for subsequent heating and consumption.

[0093] Preferably, the heating microwave oven 3 in this embodiment includes a microwave oven housing 301, and the side of the microwave oven housing 301 close to the second conveying assembly 5 has a meal-in end cover 302 that can be flipped upwards to open, and the side of the microwave oven housing 301 away from the second conveying assembly 5 has a meal-out end cover 303 that can be flipped upwards to open;

[0094] The microwave oven housing 301 is embedded with a microwave heating component;

[0095] An electric support rod 304 is installed on one side of the microwave oven body 301 near the dining end cover 302, the cylinder body of the electric support rod 304 is hinged to the microwave oven body 301, and the cylinder rod of the electric support rod 304 is hinged to the dining end cover 302;

[0096] The cylinder rod of the electric support rod 304 extends to drive the dining end cover 302 to flip open, and the cylinder rod of the electric support rod 304 contracts to drive the dining end cover 302 to flip close.

[0097] This embodiment specifically introduces the structure and working principle of the heating microwave oven 3. First, the housing of the heating microwave oven 3 is improved so that it has two openings, namely, a dining end cover 302 that opens and closes toward the inside and a dish-out end cover 303 that opens and closes toward the outside. The dining end cover 302 is driven to open and close by an electric support rod 304. The electric support rod 304 is hinged with the housing and the dining end cover 302 at the same time, and the dining end cover 302 can be opened and closed while the rod body is extended and retracted. The dish-out end cover 303 of the heating microwave oven 3 is directly opened manually by the user, and it forms an embedded structure with the main body 1, which is convenient to open and close and very beautiful. In addition, in order to cooperate with the above-mentioned second conveying component 5, an inner-box conveyor belt 305 close to the second conveying component 5 is also provided in the heating microwave oven 3, which is mainly capable of catching the lunch box 6 when the second conveying component 5 outputs the lunch box 6, and is a conveyor belt that slightly conveys a distance in the heating microwave oven 3. At the same time, this is not limited to the structure of two conveyor belts close to each other. A certain height difference can also be designed so that the lunch box 6 can fall directly into the heating microwave oven 3. However, the height difference needs to be accurately calculated to prevent the lunch box 6 from being too bumpy and scattered. In addition, the electrically opened and closed dining end cover 302 can also be used to promote the lunch box 6. No matter which method is used, the only design purpose is to use the second conveying component 5 to finally convey the lunch box 6 to the heating microwave oven 3, and carry out subsequent heating. At the same time, the microwave heating component in the heating microwave oven 3 can directly adopt the heating component in the prior art. The microwave heating method can quickly heat the lunch box 6 and shorten the waiting time.

[0098] In addition, as a more preferred technical solution: the refrigerator is integrated with a controller, and a door 101 is opened and closed on the front side of the main body 1, and a display screen 102 electrically connected to the controller is embedded on the door 101; the display screen 102 here can not only display the product category and price of the internal lunch box 6, but also integrates a payment program, which can be paid by scanning a code or paying in cash. After the payment is completed, the controller can be driven to perform subsequent control work.

[0099] The controller of this embodiment directly uses a programmable logic controller (PLC), which is programmed in advance in the controller. At the same time, the controller controls the operation of the drive motor 401 and the conveyor belt; the controller is electrically connected to the heating microwave oven 3 to control the operation of the heating microwave oven 3.

[0100] Wherein, a first sensor 501 is installed at the intersection of the first transmission component and the second transmission component 5, and a second sensor 306 is installed in the microwave oven box 301;

[0101] The first sensor 501 is electrically connected to the controller, and is used to detect the state of the first conveying component conveying the lunch box 6 to the second conveying component 5, and send a lunch box 6 position signal to the controller;

[0102] The second sensor 306 is electrically connected to the controller. The second sensor 306 is used to detect the state of the second conveying component 5 conveying the lunch box 6 to the heating microwave oven 3, and send a position signal of the lunch box 6 to the controller.

[0103] The controller of this embodiment is the control component of all functional mechanisms, and all other functional mechanisms are electrically connected to or wirelessly communicate with the controller. Among them, the above-mentioned first sensor 501 and second sensor 306 are both position sensors, which actually detect the position of the lunch box 6 in real time, so that when it reaches the specified position, it can send a position signal to the controller, and then send a control instruction through the controller to drive each functional mechanism to work.

[0104] The control principle of the controller is a relatively mature technology in the prior art and will not be described in detail here.

[0105] The control method of the automatic vending refrigerator mainly includes the following steps:

[0106] S101, the refrigerator is powered on, a thermostat is integrated in the main body 1, and the thermostat controls the refrigeration unit 2 to work according to the set temperature;

[0107] S102, after selecting the type of lunch box 6, scan the code on the display screen 102 to pay, and send a signal instruction to the controller after scanning the code to pay;

[0108] S103, the controller sends a driving instruction to the driving motor 401 according to the received signal instruction, and the driving motor 401 rotates to drive the first conveying assembly to work so as to convey the lunch box 6 to the second conveying assembly 5;

[0109] S104, the first sensor 501 detects whether the lunch box 6 delivered by the first conveying assembly is in place, and sends a position signal of the lunch box 6 to the controller. When the first sensor 501 detects that the lunch box 6 has reached the second conveying assembly 5, the controller controls the driving motor 401 to stop. When the first sensor 501 detects that the lunch box 6 has not reached the second conveying assembly 5, the driving motor 401 continues to rotate.

[0110] S105, after the second conveying assembly 5 receives the lunch box 6, the controller controls the motor of the second conveying assembly 5 to rotate and convey the lunch box 6 to the heating microwave oven 3, and at the same time, the controller controls the electric support rod 304 to extend to open the dining end cover 302;

[0111] S106, the second sensor 306 detects whether there is a box lunch 6 in the heating microwave oven 3, and sends a signal of the position of the box lunch 6 to the controller. When the second sensor 306 detects that there is a box lunch 6 in the heating microwave oven 3, the controller controls the second conveying assembly 5 to stop, and controls the electric support rod 304 to retract to close the dining end cover 302. When the second sensor 306 detects that there is no box lunch 6 in the heating microwave oven 3, the second conveying assembly 5 continues to work;

[0112] S107, the controller sends a heating signal to the microwave heating component in the heating microwave oven 3, the heating time is 2 minutes, after heating, the controller sends a stop signal to the microwave heating component in the heating microwave oven 3, and issues an alarm;

[0113] S108, the user manually opens the meal dispensing cover 302 of the heating microwave oven 3 to take the meal.

[0114] In the above technical solution, the present invention provides an automatic vending refrigerator, which has the following beneficial effects:

[0115] The refrigerator of the present invention integrates a refrigeration unit 2 and a heating microwave oven 3 therein. When the box lunch 6 is stored, the box lunch 6 in the main body 1 is kept fresh at a low temperature by the refrigeration unit 2, ensuring that the box lunch 6 can be stored for a longer time. When it is needed to be eaten, the heating microwave oven 3 at the bottom is used to heat the corresponding box lunch 6, ensuring that the box lunch 6 meets the edible temperature requirement when eaten.

[0116] The refrigerator of the present invention is designed with a first conveying assembly and a second conveying assembly 5, which can cooperate to smoothly convey the prepared lunch box 6 to the heating microwave oven 3 for subsequent consumption after heating. The conveying structure is simple, but the transmission effect is good.
