Description

Scanning heating device

The invention relates to a heating device, in particular to a barcode scanning type heating device which performs automatic heating by scanning a barcode.

There is a kind of barcode scanning type microwave oven which uses a barcode scanner to read a graphic code printed on a food package placed therein by a user to obtain microwave heating information about the food contained in the graphic code, and automatically heats the food according to the microwave heating information.

However, after the user puts the food into the barcode scanning type microwave oven, he suddenly wants to change the food to be microwaved or suddenly does not want to microwave the food, and takes the food out of the barcode scanning type microwave oven and closes the door of the barcode scanning type microwave oven. At this time, because the barcode scanning type microwave oven has obtained the microwave heating information of the food and does not know that the food has been taken out, the barcode scanning type microwave oven will still automatically perform the heating action according to the microwave heating information, causing the barcode scanning type microwave oven to be in an idling (empty-burning) state, which not only consumes electricity but also endangers the function of the barcode scanning type microwave oven.

Therefore, the purpose of the present invention is to provide a code scanning type heating device, which can solve the problems of the prior art and prevent the code scanning type heating device from operating in an idling (empty burning) state.

Therefore, the present invention provides a barcode scanning heating device for heating an object, the top of which is provided with a barcode containing heating information; the barcode scanning heating device comprises a heating chamber, a heating unit, a barcode scanner and a controller; wherein the bottom surface of the heating chamber is provided with an anti-idling barcode containing a stop operation instruction; the heating unit is provided in the heating chamber; the barcode scanner is provided on the top surface of the heating chamber; the controller is electrically connected to the heating unit and the barcode scanner; the object is placed in the heating chamber to shield the heating chamber; the heating unit is provided with a barcode scanner; the controller is electrically connected to the heating unit and the barcode scanner; the object is placed in the heating chamber to shield the heating chamber; the controller is electrically connected to the heating unit and the barcode scanner; the object is placed in the heating chamber to shield the heating chamber; the controller is electrically connected to the heating unit and the barcode scanner; the heating unit is provided with a barcode scanner ... When the anti-idling barcode is displayed, the barcode scanner scans and obtains the barcode on the top of the object and transmits it to the controller; when the object is not placed in the heating cavity, the barcode scanner scans and obtains the anti-idling barcode and transmits it to the controller; after receiving the barcode, the controller obtains the heating information from the barcode and controls the heating unit to operate according to the heating information to heat the object; after receiving the anti-idling barcode, the controller obtains the stop operation instruction from the anti-idling barcode and controls the heating unit not to operate according to the stop operation instruction.

In some embodiments of the present invention, the scanning heating device further includes a door panel and a detector electrically connected to the controller, the door panel is pivotally connected to the heating cavity to close or open an opening of the heating cavity; the detector is arranged at the opening of the heating cavity to detect whether the opening is in a closed state or an open state and accordingly generates and transmits a detection signal to the controller.

In some implementations of the present invention, when the controller determines that the opening changes from the open state to the closed state based on the detection signal, the controller controls the barcode scanner to operate and receives the barcode or the anti-idling barcode transmitted by the barcode scanner, and after obtaining the heating information contained in the barcode or the stop operation instruction contained in the anti-idling barcode, the controller controls the barcode scanner to stop operating.

In some implementations of the present invention, when the controller determines that the opening changes from the closed state to the open state based on the detection signal, the controller controls the barcode scanner to operate and receive the barcode or the anti-idling barcode transmitted by the barcode scanner. Then, when the controller determines that the opening changes from the open state to the closed state based on the detection signal, the controller waits for a period of time and then controls the barcode scanner to stop operating, and decodes the barcode or the anti-idling barcode transmitted last before the barcode scanner stops operating to obtain the heating information or the stop operation instruction.

In some implementations of the present invention, during the process in which the controller controls the heating unit to heat the object according to the heating information, when the controller determines that the opening changes from the closed state to the open state according to the detection signal, the controller controls the heating unit to stop operating.

In some embodiments of the present invention, the barcode scanning heating device is a microwave oven, the heating unit is a microwave heater, the barcode is a two-dimensional graphic code, and the heating information includes a microwave power parameter and a microwave time parameter.

In some embodiments of the present invention, the inner bottom surface of the heating cavity is provided with an item placement area for placing the item, and the anti-idling barcode is arranged in the item placement area, and the position of the barcode scanner arranged on the inner top surface of the heating cavity corresponds to the item placement area.

In some implementations of the present invention, the anti-idling barcode is a two-dimensional graphic code with a low error tolerance rate. When the object is placed in the object placement area without completely covering the anti-idling barcode, the barcode scanner scans and obtains the barcode on the top of the object and the local anti-idling barcode and transmits them to the controller. The controller can decode the barcode and obtain the heating information but cannot decode the local anti-idling barcode and cannot obtain the stop operation instruction.

The effect of the present invention is that by setting the anti-idling barcode on the bottom surface of the heating cavity, when the object is not placed in the heating cavity, the barcode scanner scans and obtains the anti-idling barcode and transmits it to the controller. When the controller receives the anti-idling barcode, it means that the object is not placed in the heating cavity. Then, the controller controls the heating unit to stop operating according to the stop operation instruction obtained from the anti-idling barcode, thereby preventing the scanning type heating device from operating in an idling (empty burning) state.

Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

Referring to FIG. 1 and FIG. 2 , an embodiment of the novel barcode scanning heating device is shown. The barcode scanning heating device 1 is used to heat an object 2. The top surface of the object 2 has a barcode 21 containing heating information. In the present embodiment, the object 2 is a food (such as a convenience store bento), but is not limited to this. The barcode 21 is a graphic code, such as a QR code, and the heating information includes a heating power parameter and a heating time parameter.

The barcode scanning heating device 1 mainly includes a heating chamber 10, a heating unit 11, a barcode scanner 12 and a controller 13; the inner bottom surface 101 of the heating chamber 10 is provided with an item placement area 102 for instructing the user to place the item 2, and the item placement area 102 is provided with an anti-idling barcode 103 containing a stop operation instruction; and as shown in FIG1 , the item placement area 102 may refer to, for example, the middle area on the surface of a carrier plate 104 disposed on the inner bottom surface 101 of the heating chamber 10, or the middle area of the inner bottom surface 101 of the heating chamber 10 (when the carrier plate 104 is removed or omitted). The anti-idling barcode 103 is, for example but not limited to, a two-dimensional graphic code, such as a QR code.

The heating unit 11 is disposed in the heating chamber 10, for example, on the inner wall surface (side wall surface and/or top wall surface) of the heating chamber 10. The barcode scanner 12 is disposed on the inner top surface of the heating chamber 10 and corresponds to the object placement area 102. The controller 13 is electrically connected to the heating unit 11 and the barcode scanner 12 to control the operation (activation or not) of the heating unit 11 and the barcode scanner 12.

Therefore, when the barcode scanner 12 is activated, when the object 2 is placed in the object placement area 102 and covers the anti-idling barcode 103, the barcode scanner 12 will scan and obtain the barcode 21 on the top of the object 2 and transmit it to the controller 13; and when the object 2 is not placed in the object placement area 102, the barcode scanner 12 will scan and obtain the anti-idling barcode 103 and transmit it to the controller 13.

Therefore, when the controller 13 receives the barcode 21, it will decode the barcode 21 and obtain the heating information from the barcode 21, and control the heating unit 11 to operate to heat the object 2 according to the heating information; and when the controller 13 receives the anti-idling barcode 103, it will decode the anti-idling barcode 103 and obtain the stop operation instruction from the anti-idling barcode 103, and control the heating unit 11 not to operate (or stop operating) according to the stop operation instruction. In this way, when the object 2 is not placed in the heating cavity 10 or the object 2 is taken out again after being placed in the heating cavity 10, the controller 13 will receive the anti-idling barcode 103 and control the heating unit 11 not to operate, thereby preventing the barcode scanning heating device 1 from being in an idling (empty burning) state.

Specifically, the code scanning type heating device 1 of the present embodiment is a microwave oven, therefore, the heating unit 11 is a microwave heater, the heating firepower parameter is a microwave firepower parameter, and the heating time parameter is a microwave time parameter.

In addition, the barcode scanning heating device 1 further includes a door panel 14 and a detector 15 electrically connected to the controller 13. The door panel 14 is pivotally connected to the heating chamber 10 to close or open an opening 105 of the heating chamber 10. The detector 15 can be, for example but not limited to, a proximity sensor, which is arranged at the opening 105 of the heating chamber 10 (for example, around the opening 105) to detect whether the opening 105 is in a closed state closed by the door panel 14 or in an open state not closed by the door panel 14, and accordingly generates a detection signal and transmits the detection signal to the controller 13. When the controller 13 determines that the opening 105 changes from the open state to the closed state according to the detection signal, the controller 13 controls the barcode scanner 12 to operate and receives the barcode 21 or the anti-idling barcode 103 transmitted by the barcode scanner 12, and after obtaining the heating information contained in the barcode 21 or the stop operation instruction contained in the anti-idling barcode 103, the controller 13 controls the barcode scanner 12 to stop operating.

In another embodiment, the controller 13 may also control the barcode scanner 12 to operate and receive the barcode 21 or the anti-idling barcode 103 transmitted by the barcode scanner 12 when the opening 105 changes from the closed state to the open state according to the detection signal. Then, after the controller 13 determines that the opening 105 changes from the open state to the closed state according to the detection signal, it waits for a period of time (for example, 3 seconds or 5 seconds) and then controls the barcode scanner 12 to stop operating, and decodes the barcode 21 or the anti-idling barcode 103 transmitted last before the barcode scanner 12 stops operating to obtain the heating information or the stop operation instruction.

And in the process that the controller 13 controls the heating unit 11 to heat the object 2 according to the heating information, when the controller 13 determines that the opening 105 changes from the closed state to the open state according to the detection signal (for example, during the heating process, the door panel 14 is suddenly opened), the controller 13 controls the heating unit 11 to stop operating.

In addition, in this embodiment, the anti-idle barcode 103 adopts a two-dimensional graphic code with a low error tolerance rate. The low error tolerance rate means that as long as a small area (for example, 7% of the area) of the two-dimensional graphic code is unclear or blocked, the two-dimensional graphic code cannot be successfully decoded. Therefore, when the object 2 is placed in the object placement area 102 and does not completely cover the anti-idling barcode 103, the barcode scanner 12 scans and obtains the barcode 21 on the top of the object 2 and the local anti-idling barcode 103 and transmits them to the controller 13. The controller 13 can decode the barcode 21 to obtain the heating information but cannot decode the local anti-idling barcode 103 and cannot obtain the stop operation instruction. In this way, the controller 13 is prevented from misjudging and prohibiting the heating unit 11 from heating the object 2 placed in the heating chamber 10.

In summary, the above embodiment sets the anti-idling barcode 103 containing the stop operation instruction on the bottom surface of the heating chamber 10, so that when the object 2 is placed in the heating chamber 10, the barcode scanner 12 scans and obtains the barcode 21 on the top surface of the object 2 and transmits it to the controller 13, and when the object 2 is not placed in the heating chamber 10, the barcode scanner 12 scans and obtains the anti-idling barcode 103 and transmits it to the controller 13, thereby, if the controller 13 receives the barcode 21, the controller 13 will receive the barcode 21. If the controller 13 receives the barcode 21, the heating information is obtained from the barcode 21 and the heating unit 11 is controlled to operate to heat the object 2 according to the heating information; if the controller 13 receives the anti-idling barcode 103, it means that the object 2 is not placed in the heating chamber 10, then the controller 13 controls the heating unit 11 not to operate according to the stop operation instruction obtained from the anti-idling barcode 103, thereby preventing the scanning type heating device 1 from operating in an idling (empty burning) state, thereby truly achieving the effect and purpose of the present invention.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
