By the way, neither of Patent Documents 1 and 2 describes the timing at which the barcode scanner or the first or second barcode reading device reads the barcode. However, if these reading devices are always enabled to read barcodes, there is a risk that the barcode on the container of the food will be read by mistake when the heated food is taken out from inside the heating chamber. In this case, since the food has already been taken out from the heating chamber, there is a possibility that heating may be performed without any food present in the heating chamber. In other words, the no-load operation places a burden on the heating section of the cooking device, such as the magnetron, resulting in a problem of shortening the life of the device.

One aspect of the present invention aims to suppress no-load operation.

In order to solve the above problems, a heating cooker according to one aspect of the present invention includes a heating chamber, a reading device that reads an information code for cooking food, and an information code read by the reading device. a heating control unit that controls the heating of the food placed in the heating chamber based on the heating temperature; a movement direction determination unit that determines the moving direction of the food in the heating chamber; and a reader that controls the reading operation of the reading device. a control unit, the reading control unit controls the reading device to read the information code for a predetermined period of time after the moving direction determining unit determines that the moving direction of the food is in the direction of leaving the heating chamber. Stopping the reading operation or canceling the information code read by the reading device at a predetermined time when the moving direction determining section determines that the moving direction of the food is in the direction of leaving the heating chamber. It is a feature.

According to one aspect of the present invention, no-load operation can be suppressed.

It is an explanatory diagram.

The information code is used to heat and cook food. For example, the information code includes information indicating the type of food and information (heating information) indicating conditions for heating and cooking the food indicated by the type. The heating information is information necessary for heating cooking, and includes the heating time in the heating cooker 1 and the wattage of high frequency output. Specifically, the information code contains information indicating the type of food, such as whether the food is a bento (or even the type of bento) or a rice ball (or even the type of onigiri), and the information indicated. It includes heating information including heating time and high frequency output wattage according to the food. This information code is given to the food or food container by, for example, printing or a sticker. Note that since the information code is used to heat and cook the specified food, it contains only information that specifies the food, and the heating information of the specified food is acquired from the external server 51 (FIG. 8). Good too. Further, the information code may include only food heating information.

Note that the information code may be a two-dimensional code, as shown in FIG. 6(a), or a one-dimensional barcode, as shown in FIG. 6(b), for example. Note that the information code may be anything that can indicate the type of food, and is not particularly limited to a bar code or the like.

(Control device)
FIG. 7 is a block diagram showing the configuration of a control device included in the cooking device 1. As shown in FIG. The control device includes a control section 22 that controls the operation of the cooking device 1 . The control unit 22 is composed of, for example, a microcomputer, and includes a CPU, ROM, and RAM.

As shown in FIG. 7, the control section 22 includes an operation panel 11, a heating operation section 23, a reading device 16, a reading area illumination section 21, a reading result notification section 24, a front door opening/closing detection section 25, and a memory (storage section). 52 are connected. The front door opening/closing detection unit 25 includes, for example, a switch that is turned on when the front door 12 is closed, and detects the open state and closed state of the front door 12.

The heating operation unit 23 is an operation unit that heats the food placed in the heating chamber 13, and is, for example, a microwave output device or a heater. The reading result notification unit 24 is a buzzer or a sound generating unit, and is controlled by the control unit 22 to notify the user of the success or failure of reading the information code by the reading device 16.

The control unit 22 can communicate with the server 51 using, for example, an Internet line. Heating information corresponding to the types of various foods is registered in the server 51. The control unit 22 acquires heating information according to the type of food acquired by the reading device 16 by reading the information code from the server 51, and controls the heating operation unit 23 so that the food is heated according to the acquired heating information. Control. Note that the cooking device 1 itself may have heating information depending on the type of food. In this case, the heating cooker 1 does not need to communicate with the server 51.

Further, the control unit 22 includes a determination unit 22a (moving direction determination unit) that determines the movement direction (insertion direction or removal direction) of the food 40 within the heating chamber 13, and a heating operation unit 23 based on the determination result of the determination unit 22a. The reading control section 22c includes a heating control section 22b that controls the heating operation of the reading device 16, and a reading control section 22c that controls the reading operation of the reading device 16 based on the determination result of the determination section 22a.

FIG. 8 is an explanatory diagram showing a method for determining the moving direction of food in the cooking device 1. As shown in FIG.

The determination unit 22a determines the moving direction of the food 40 within the heating chamber 13 based on the image captured by the camera 31. The determination unit 22a determines the moving direction of the food 40 from the two images received from the camera 31. That is, the determination unit 22a determines that among the two received images, the image of the first received food (QR code) 40 is designated as 40a, and the image of the second received food (QR code) 40 is designated as 40b. As shown by reference numeral 1181 in FIG. 8, if the image 40a is on the outside of the heating chamber 13 with respect to the image 40b, the moving direction of the food (QR code) 40 is on the inside of the heating chamber 13 (in the direction of arrow X). It is determined that On the other hand, as shown by reference numeral 1182 in FIG. direction). Note that the determination unit 22a may determine the moving direction based on the image of the entire food 40 (including the QR code), but instead of the image of the food 40, the information code of the food 40 (in the case of FIG. 8, the QR code) is used. The moving direction of the food 40 may be determined from the image.

If the determination result of the determination unit 22a is a result indicating that the food 40 is moving inside the heating chamber 13, that is, to the inside of the chamber, the heating control unit 22b permits the heating operation by the heating operation unit 23; If the result indicates that the food 40 has moved to the outside of the heating chamber 13, that is, to the outside of the chamber, the heating operation by the heating operation unit 23 is not permitted.

If the determination result of the determination unit 22a is a result indicating that the food 40 has moved to the outside of the heating chamber 13, that is, to the outside of the chamber, the reading control section 22c causes the reading device 16 to read the information code for a predetermined period of time. Stopping the operation or canceling the information code read by the reading device 16 at a predetermined time. Note that the information code read by the reading device 16 includes heating information necessary for heating cooking. The heating information refers to the heating time in the cooking device 1 and the wattage of high frequency output.

The reading control unit 22c releases the stoppage of the information code reading operation by the reading device 16 after a predetermined period of time has elapsed, or cancels the operation of canceling the information code read by the reading device. Here, the predetermined time may be arbitrarily set, and may be set at least to the time from when the food 40 is completely removed from the heating chamber 13 until it passes the reading position by the reading device 16. By setting the predetermined time in this way, it is possible to further reduce the possibility that the information code will be read again by the reading device 16 when the food is taken out from the heating chamber 13 after heating.

Preferably, the predetermined period of time starts at the time when the determination unit 22a determines that the moving direction of the food 40 within the heating chamber 13 is toward the outside of the chamber. In this case, the reading operation by the reading device 16 will be stopped after the food 40 has moved to the outside of the storage, so even if the food 40 taken out from the heating storage 13 passes the reading position of the reading device 16. , there is almost no possibility that the information code of the food 40 will be read.

The completion of the predetermined time may be, for example, when the front door opening/closing detection section 25 detects that the front door 12 is closed. Specifically, the front door opening/closing detection section 25 detects that the front door 12 is opened, and the determination section 22a determines that the moving direction of the food 40 in the heating chamber 13 is toward the outside of the chamber. After the determination, the reading operation by the reading device 16 is stopped after a predetermined period of time, or the reading operation by the reading device 16 is stopped after the door opening/closing detection section 25 detects that the front door 12 is closed. unlock. In this case, in order to take out the cooked food 40 from the heating chamber 13, it is necessary to open the front door 12, so the food 40 is taken out from the heating chamber 13 with the front door 12 open. . At this time, the reading device 16 starts to stop the reading operation. Then, after a predetermined period of time has elapsed or after the front door 12 is closed, the stoppage of the reading operation by the reading device 16 is canceled. Thereby, the information code of the food 40 can be read by the reading device 16 next time when the front door 12 is opened to put the food 40 into the heating chamber 13 for cooking.

The heating information included in the information code read by the reading device 16 is stored in the memory 52. Thereby, since the heating information for the food whose information code has been read once is registered in the memory 52 of the heating cooker 1, it is not necessary to acquire the heating information from outside the heating cooker 1 every time the information code is read.

(Operation of heating cooker 1)
In the above configuration, the operation of the cooking device 1 will be explained below. Here, a case will be described in which the food 40 is a boxed lunch with an information code provided on the top surface of the container, and the boxed lunch is heated in the cooking device 1.

First, the user confirms the guidance display 20 on the operation panel 11 (for example, "Open the door and hold the information code over the red light"). The user then opens the front door 12 in accordance with this guide display 20. When the front door opening/closing detection section 25 detects the open state of the front door 12, the control section 22 operates the reading device 16 and the reading area illumination section 21.

Next, the user moves the lunch box according to the guide display 20 on the operation panel 11 so that the information code enters the reading area 19 of the reading device 16 (so that the information code is illuminated by red light).

Through this operation, the reading device 16 reads the information code given to the lunch box. When the reading device 16 successfully reads the information code, the control section 22 causes the reading result notification section 24 to notify the user of the reading result. The operation of the reading result notification unit 24 in this case is, for example, an operation of emitting a continuous sound such as "beep", an operation of emitting a voice saying "information code reading was successful", or both.

When the user is informed by the reading result notifying unit 24 that the information code has been successfully read, the user moves the lunch box to the inside of the heating oven 13 and places it at a predetermined position (on the flat plate 13c) inside the heating oven 13. do. At this time, the control unit 22 determines that the moving direction of the lunch box is on the inside of the heating chamber 13 by the determination unit 22a, and based on this determination result, the heating control unit 22b performs the heating control, that is, the heating operation unit 23 performs the heating operation. is allowed.

When the control unit 22 successfully reads the information code, it communicates with the server 51 and acquires from the server 51 heating information corresponding to the type of food indicated by the information code. Thereafter, when the user closes the front door 12 and presses the start button on the operation panel 11, the control unit 22 heats the lunch box in the heating warehouse 13 according to the acquired heating information.

Thereafter, in the control unit 22, the user closes the front door 12, operates the heating change button 11a on the operation panel 11, and presses the start button. Then, when the start button is pressed, the lunch box in the heating warehouse 13 is heated according to the acquired heating information.

On the other hand, if reading of the information code by the reading device 16 fails, the control section 22 causes the reading result notification section 24 to notify the user of the reading result. The operation of the reading result notification unit 24 in this case is, for example, an operation of emitting an intermittent sound such as "beep, beep, beep", an action of emitting a voice saying "reading of information code has failed", or both.

When the user is notified by the reading result reporting unit 24 that the information code has failed to read, the user reads the information code again so that the information code enters the reading area 19 of the reading device 16 (so that the red light shines on the information code). , move the lunch box. As a result, the operation when the information code is successfully read is as described above.

When the heating of the lunch box is completed in the above manner, the user is notified of this, and the user takes out the lunch box from the heating chamber 13. By taking out the lunch box from inside the heating warehouse 13, the determination unit 22a of the control unit 22 determines that the moving direction of the lunch box is on the outside of the heating warehouse 13. Based on the determination result of the determination section 22a (the moving direction of the lunch box is outside the heating chamber 13), the heating control section 22b does not permit the heating operation section 23 to perform the heating operation. Further, based on the determination result of the determination unit 22a (the moving direction of the lunch box is outside the heating chamber 13), the reading control unit 22c stops the reading operation of the information code by the reading device 16 for a predetermined period of time.

(effect)
According to the heating cooker 1 having the above configuration, when the determining unit 22a determines that the moving direction of the food 40 is the direction in which the food 40 is to exit from the heating chamber 13, the reading control unit 22c controls the reading device 16 to read the information code for a predetermined period of time. or cancel the information code read by the reading device 16 at a predetermined time. As a result, when there is no food 40 in the heating chamber 13, the information code is not read by the reader 16 for a predetermined period of time, or the information code read by the reader 16 at a predetermined time is canceled. Heating operation (no-load operation) by the operation unit 23 is also not performed. Therefore, the cooking device 1 can suppress no-load operation.

Further, according to the heating cooker 1 having the above configuration, the determination unit 22a can easily determine the moving direction of the food 40 by analyzing the image taken by the camera 31.

Furthermore, according to the heating cooker 1 having the above configuration, after a predetermined period of time has elapsed, the stoppage of the reading operation of the reading device 16 is canceled, or the operation of canceling the information code read by the reading device 16 is canceled. Therefore, the information code of the food 40 to be heated and cooked next can be read. Here, the predetermined time may be arbitrarily set, and may be set at least to the time from when the food is completely removed from the heating chamber until it passes the reading position by the reading device. By setting the predetermined time in this way, it is possible to further reduce the possibility that the information code will be read again by the reading device 16 when the food is taken out from the heating chamber 13 after heating.

[Embodiment 2]
Other embodiments of the invention will be described below. For convenience of explanation, members having the same functions as the members described in the above embodiment are given the same reference numerals, and the description thereof will not be repeated. FIG. 9 is a block diagram showing the configuration of a control device included in the cooking device 2. As shown in FIG. FIG. 10 is an explanatory diagram showing a method of detecting the moving direction of food in the cooking device 2 shown in FIG.

(Overview of heating cooker 2)
As shown in FIGS. 9 and 10, the cooking device 2 according to the present embodiment includes a movement sensor 41 (movement detection section) that detects movement of the food 40 instead of the camera 31 of the cooking device 1. Further, the determination unit 22a (movement direction determination unit) of the control device according to the present embodiment determines whether the heating chamber The direction of movement of food 40 within 13 is determined. The other configuration of the heating cooker 2 is the same as that of the heating cooker 1.

(Motion sensor 41)
As shown by reference numeral 1101 in FIG. 10, the movement sensor 41 is provided in the lower part of the inside of the control frame 15 so as to be located on the right side of the reading device 16. By providing the motion sensor 41 outside the heating chamber 13 in this manner, the influence of heat on the motion sensor 41 can be reduced. Note that the position where the movement sensor 41 is provided is not limited to such a configuration, and may be any position that can detect the movement of the food 40.

Further, as shown by reference numeral 1102 in FIG. 10, the detection position 41a of the movement of the food 40 by the movement sensor 41 is closer to the inside of the heating chamber 13 than the information code reading position 16a. For example, the motion sensor 41 is installed on the control frame 15 so that the detection position 41a is located inside the heating refrigerator 13, tilting toward the inside of the refrigerator. Further, the reading device 16 is installed on the control frame 15 so that the reading position 16a is located outside the heating refrigerator 13 so as to be inclined toward the outside of the heating refrigerator 13. Thereby, the detection position 41a can be more reliably placed inside the heating chamber 13 than the reading position 16a.

(Control device)
The determining unit 22a determines the moving direction of the food 40 within the heating chamber 13 based on the order in which the reading device 16 reads the information code and the movement sensor 41 detects the movement of the food 40. Here, as shown by reference numeral 1102 in FIG. 10, the detection position 41a is closer to the inside of the heating chamber 13 than the reading position 16a. Therefore, when the movement sensor 41 detects the movement of the food 40 at the detection position 41a after the reading device 16 reads the information code at the reading position 16a, the determination unit 22a determines that the moving direction of the food 40 is It is determined that it is inside (arrow X direction). On the other hand, if the movement sensor 41 detects the movement of the food 40 at the detection position 41a before the reading device 16 reads the information code at the reading position 16a, the determination unit 22a determines that the moving direction of the food 40 is It is determined that it is outside (direction of arrow Y).

(effect)
According to the heating cooker 2 having the above configuration, the determination unit 22a can easily determine the moving direction of the food 40 based on the order of reading the information code by the reading device 16 and detecting the movement of the food 40 by the movement sensor 41. I can do it.

Furthermore, since the detection position 41a is located closer to the inside of the heating chamber 13 than the reading position 16a, when the food 40 is taken out from the heating chamber 13, the movement of the food 40 is detected before the food 40 passes the reading position 16a. will be held. Therefore, the reading control unit 22c can stop the reading operation by the reading device 16 before the food 40 passes the reading position 16a, or can reliably cancel the information code read by the reading device 16. I can do it. Therefore, the cooking device 2 can reliably suppress no-load operation.

(Modified example)
In the cooking device 2, the detection position 41a of the movement of the food 40 by the movement sensor 41 may be on the outside of the heating chamber 13 rather than the information code reading position 16a. At this time, if the movement sensor 41 detects the movement of the food 40 at the detection position 41a before the reading device 16 reads the information code at the reading position 16a, the determination unit 22a determines that the movement direction of the food 40 is It is determined that it is inside the refrigerator. On the other hand, if the movement sensor 41 detects the movement of the food 40 at the detection position 41a after the reading device 16 reads the information code at the reading position 16a, the determination unit 22a determines that the moving direction of the food 40 is It is determined that it is outside.

When the determining unit 22a determines that the moving direction of the food 40 is outside the heating chamber 13, the reading control unit 22c cancels the information code read by the reading device 16 at a predetermined time. Here, the start of the predetermined time may be set, for example, before the time when the food 40 passes the reading position 16a by the reading device 16. Thereby, even if the determination unit 22a determines the moving direction of the food 40 after the food 40 passes the reading position 16a, the reading control unit 22c cancels the information code read by the reading device 16. I can do it. Therefore, the cooking device 2 can suppress no-load operation.

[Example of implementation using software]
The control blocks of the control unit 22 (particularly the determination unit 22a, heating control unit 22b, and reading control unit 22c) may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software. It may be realized by

In the latter case, the control unit 22 includes a computer that executes instructions of a program that is software that implements each function. This computer includes, for example, at least one processor (control device) and at least one computer-readable recording medium storing the above program. In the computer, the processor reads the program from the recording medium and executes the program, thereby achieving the object of the present invention. As the processor, for example, a CPU (Central Processing Unit) can be used. As the recording medium, in addition to "non-temporary tangible media" such as ROM (Read Only Memory), tapes, disks, cards, semiconductor memories, programmable logic circuits, etc. can be used. Further, the computer may further include a RAM (Random Access Memory) for expanding the above program. Furthermore, the program may be supplied to the computer via any transmission medium (communication network, broadcast waves, etc.) that can transmit the program. Note that one aspect of the present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.

〔summary〕
The heating cooker according to aspect 1 of the present invention includes a heating chamber, a reading device for reading an information code for cooking food, and a heating chamber arranged in the heating chamber based on the information code read by the reading device. a heating control unit that controls the heating of the food that has been heated, a movement direction determination unit that determines the moving direction of the food in the heating warehouse, and a reading control unit that controls the reading operation of the reading device, The control unit is configured to stop the reading operation of the information code by the reading device for a predetermined period of time after the movement direction determination unit determines that the movement direction of the food is in the direction of leaving the heating chamber; If the moving direction determining section determines that the moving direction of the food is in the direction of leaving the heating chamber, the information code read by the reading device at a predetermined time is canceled.

According to the above configuration, when the moving direction determining unit determines that the moving direction of the food is the direction of leaving the heating chamber, the reading operation of the information code by the reading device is stopped for a predetermined period of time, or the reading operation of the information code by the reading device is stopped for a predetermined period of time. to cancel the information code read by the reading device. Therefore, when taking food out of the heating chamber after cooking, the information code is not read even if it passes the reading position of the reader, or the information code that is read when the food passes the reading position of the reader is Canceled. Therefore, the cooking device can suppress no-load operation.
