Description

Technical Field

[0001] This utility model relates to an intelligent microwave oven for refrigerated vending machines, belonging to the technical field of refrigerated vending machine accessories. Background Technology

[0002] In today's fast-paced life, refrigerated vending machines are widely used in crowded places such as shopping malls, schools, hospitals, and subway stations, providing people with a convenient way to purchase goods. These refrigerated vending machines are typically used to store and sell various refrigerated foods, such as refrigerated boxed meals, frozen dumplings, microwaveable soups, and other ready-to-eat or easily processed foods. However, consumers often need to heat these refrigerated foods before eating them.

[0003] Currently, most refrigerated vending machines provide heating equipment, but these are mostly ordinary microwave ovens. Different refrigerated foods require significantly different heating times and power due to variations in type, quantity, and ingredients. For example, a serving of refrigerated rice and a serving of refrigerated soup have drastically different heating requirements. Insufficient heating time may result in underheating, affecting taste and food safety; while excessive heating can lead to overheating, nutrient loss, or even burning, severely impacting food quality. Ordinary microwave ovens typically require users to manually set heating time and power, which can be difficult for consumers unfamiliar with food heating techniques to achieve the desired temperature, affecting taste. Furthermore, when consumers purchase multiple different refrigerated foods, they need to adjust heating parameters repeatedly based on the characteristics of each food, making the process cumbersome. Therefore, developing a smart microwave oven that can automatically control the heating level based on product information is of significant practical importance. Utility Model Content

[0004] In order to solve the above-mentioned problems existing in the prior art, this utility model provides an intelligent microwave oven for refrigerated vending machines.

[0005] The technical solution of this utility model is as follows: A smart microwave oven for refrigerated vending machines includes a microwave oven body with a barcode scanner embedded in it. The microwave oven body also houses a controller and a microwave generator. The controller is electrically connected to both the barcode scanner and the microwave generator. The barcode scanner is used to scan and read barcode labels affixed to food packaging boxes to display food serial number information. The controller retrieves its preset heating program based on the food serial number information on the barcode label scanned by the barcode scanner to control the microwave generator to perform the required microwave generation.

[0006] The microwave oven body has a microwave oven door on its front side wall. The microwave oven door can be opened and closed on the microwave oven body. The barcode scanner is embedded in the microwave oven door, and the scanning end of the barcode scanner is facing the side wall of the microwave oven door away from the microwave oven body.

[0007] The microwave oven door is equipped with an observation window for users to observe the contents of the microwave oven and a handle for users to pull the microwave oven door. The barcode scanner is embedded in the microwave oven door within the observation window.

[0008] The microwave oven door and the microwave oven body are connected by an electronic lock. The electronic lock is also electrically connected to the controller. The controller detects the closed state of the electronic lock. Only when the controller detects that the electronic lock is closed can it control the microwave generator to generate microwaves.

[0009] This utility model has the following beneficial effects: This invention involves embedding a barcode scanner in the microwave oven body, along with a controller and barcode labels displaying food serial numbers on food packaging boxes. When a consumer uses the microwave, they simply align the barcode label with the scanner. After scanning the barcode, the controller retrieves the pre-set heating program based on the serial number and controls the microwave oven to perform the corresponding heating operation. This automatically sets the heating time and power. The consumer then places the food packaging box into the microwave oven and waits for it to heat automatically. Compared to existing technologies, this eliminates the need for manual settings of the microwave oven's operating parameters, ensuring optimal heating of the food and offering advantages such as ease of operation and guaranteed food quality.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0013] Example: Please refer to Figures 1-4 A smart microwave oven for refrigerated vending machines includes a microwave oven body 1. A microwave oven door 5 is located on the front wall of the microwave oven body 1, and the door 5 can be opened and closed for consumer use. A barcode scanner 2 is embedded in the microwave oven body 1, specifically within the microwave oven door 5. The scanning end of the scanner 2 faces the side wall of the microwave oven door 5 away from the microwave oven body 1, enabling it to scan objects located in front of the microwave oven door 5. A controller 3 and a microwave generator 4 are also located inside the microwave oven body 1. The controller 3 is electrically connected to both the barcode scanner 2 and the microwave generator 4, and can transmit data accordingly. The barcode scanner 2 is used to scan and read barcode labels affixed to food packaging boxes to display food serial number information. The barcode label can be a one-dimensional barcode or a two-dimensional barcode, depending on the specific requirements. The controller 3 retrieves its own preset heating program based on the food serial number information on the barcode label scanned and read by the barcode scanner 2 to control the microwave generator 4 to perform the required microwave generation work, thereby enabling the food inside the microwave oven 1 to perform the required heating work.

[0014] With the aforementioned setup, when a consumer uses the microwave oven, they simply align the barcode label on the food packaging box with the barcode scanner 2. After the scanner 2 scans and reads the barcode label, the controller 3 can retrieve its preset heating program based on the food serial number information scanned by the scanner 2 to control the microwave oven body 1 to perform the corresponding heating work. That is, it can automatically set the heating time and power. At this time, the consumer opens the microwave oven door 5, puts the food packaging box into the microwave oven body 1, closes the microwave oven door 5, and then waits for it to heat automatically. The operation is simple and convenient, and it effectively prevents the food from becoming less palatable due to problems with the degree of heating.

[0015] It should be noted that the preset heating programs in the controller 3 can be selected and set according to actual conditions. Specifically, heating programs A, B, C, ... can be set, with heating program A corresponding to food item number one, heating program B corresponding to food item number two, heating program C corresponding to food item number three, and so on. Then, the controller 3, based on the food item number information scanned and read by the barcode scanner 2, retrieves the corresponding A / B / C / ... heating program to control the microwave generator 4. The controller 3, as a common component in the art, has preset control programs that are known to those skilled in the art. Those skilled in the art can clearly understand the implementation method of the solution provided in this embodiment. Furthermore, this embodiment does not involve any improvements to the computer program; all computer programs involved are known techniques in the prior art.

[0016] To facilitate consumer use, in this embodiment, the microwave oven door 5 is also equipped with an observation window 6 for the consumer to observe the contents of the microwave oven body 1 and a handle 7 for the consumer to pull the microwave oven door 5. The consumer can observe the food inside the microwave oven body 1 in real time through the observation window 6, and can easily open the microwave oven door 5 using the handle 7. To ensure the normal operation of the barcode scanner 2, the barcode scanner 2 is embedded in the microwave oven door 5 within the observation window 6, ensuring that the scanning part of the barcode scanner 2 can effectively scan external objects.

[0017] To ensure the safe operation of the microwave oven body 1 and prevent the microwave oven body 1 from continuing to operate when the microwave oven door 5 is open, in this embodiment, the microwave oven door 5 and the microwave oven body 1 are locked together by an electronic lock. The electronic lock is also electrically connected to the controller 3. The controller 3 can detect the closed state of the electronic lock. When the controller 3 detects that the electronic lock is in the closed state, it can control the microwave generator 4 to generate microwaves. When the controller 3 detects that the electronic lock is in the open state, it will not control the microwave generator 4 to generate microwaves, thus effectively preventing the microwave oven body 1 from continuing to operate when the microwave oven door 5 is open. In this embodiment, the electronic lock specifically includes a first magnetic block 8 embedded in the microwave oven door 5 and a Hall sensor 9 embedded in the microwave oven body 1. The Hall sensor 9 is electrically connected to the controller 3. When the microwave oven door 5 is closed on the microwave oven body 1, the first magnetic block 8 and the Hall sensor 9 are in contact. At this time, the magnetic field strength detected by the Hall sensor 9 reaches its preset value, and the Hall sensor 9 can transmit a closing signal to the controller 3, informing the controller 3 that the microwave oven door 5 is closed and allowing it to control the microwave generator 4 to operate. When the microwave oven door 5 leaves the microwave oven body 1, the first magnetic block 8 separates from the Hall sensor 9, and the magnetic field strength detected by the Hall sensor 9 weakens, falling below its preset value. The Hall sensor 9 can then transmit an opening signal to the controller 3, informing the controller 3 that the microwave oven door 5 is open and thus preventing the microwave generator 4 from continuing to operate. The electronic lock may also include a slide groove 10 formed on the microwave oven body 1. The slide groove 10 is arc-shaped. A slider 11 is also provided on the microwave oven door 5. The slider 11 is adapted to the arc-shaped structure of the slide groove 10. The end of the slider 11 away from the microwave oven door 5 is slidably inserted into the slide groove 10. A second magnetic block 12 is fixedly provided on the end of the slider 11 that is inserted into the slide groove 10. An electromagnet 13 is provided on the bottom wall of the slide groove 10. When the microwave oven door 5 is closed on the microwave oven body 1, the second magnetic block 12 can be attached to the electromagnet 13. When the electromagnet 13 is energized, it can attract the second magnetic block 12 together, thereby locking the microwave oven door 5 on the microwave oven body 1. The electromagnet 13 is also electrically connected to the controller 3. When the controller 3 receives the signal from the Hall sensor 9, or when the microwave oven door 5 is in the closed state on the microwave oven body 1, the controller 3 controls the electromagnet 13 to be energized to lock the microwave oven door 5. After the barcode scanner 2 scans the barcode label, the controller 3 controls the electromagnet 13 to be de-energized, so as to unlock the microwave oven door 5 so that the consumer can open the microwave oven door 5 to put food in.A guide block 14 can also be fixedly mounted on the slider 11. The guide block 14 is slidably mounted in the slide groove 10. A spring 15 is sleeved on the slider 11 between the guide block 14 and the electromagnet 13. The two ends of the spring 15 are fixedly connected to the guide block 14 and the electromagnet 13, respectively. When the microwave oven door 5 is closed on the microwave oven body 1, the spring 15 is in a compressed state. This allows the spring 15 to push the guide block 14 through its own reset motion after the electromagnet 13 is de-energized, thereby driving the slider 11 to move along the slide groove 10. This allows the microwave oven door 5 to pop out, so that the consumer knows that the microwave oven door 5 is in the unlocked state, thus facilitating the consumer's use.
