Description

The present invention relates to a cooking device that heats food placed in a heating chamber.

Conventionally, for example, in convenience stores, a service is provided in which food such as bento boxes sold is heated by a cooking device such as a microwave oven and handed to a customer.

The suitable heating temperature and heating time for heating food differ depending on the type of food. Therefore, in the cooking apparatus shown in Patent Documents 1 and 2, the barcode indicating the type of food written on the container of food is read by a reading device, and the heating information (heating temperature and heating time) according to the type of food is read. ) Is used to heat the food.

Specifically, in the configuration described in Patent Document 1, a barcode scanner is connected to a microwave oven, and a user manually operates the barcode scanner to read the barcode written on the food container to read the type of food. We have obtained heating information according to the above.

Further, in the configuration described in Patent Document 2, the barcode written on the food container is held over the first barcode reader provided on one side of the front surface of the cooking device to read the barcode. As a result, heating information according to the type of food is obtained. Alternatively, the food contained in the container is placed inside the heating chamber of the heating cooker, and the barcode written on the food container is read by the second barcode reading device provided on the top wall of the heating chamber. We have obtained heating information according to the type of food.

Japanese Unexamined Patent Publication No. 2006-64362 Utility Model Registration No. 3076649

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 in a state where the barcode can be read, there is a risk that the barcode of the container of the food may be erroneously read when the heated food is taken out from the inside of the heating chamber. In this case, since the food has already been taken out from the heating chamber, heating may be performed in a state where the food does not exist in the heating chamber. That is, the no-load operation puts a burden on the heating part of the cooking device, for example, the magnetron, which causes a problem of shortening the life of the equipment.

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

In order to solve the above problems, the heating cooker according to one aspect of the present invention includes a heating cabinet, a reading device for reading an information code for cooking food, and an information code read by the reading device. Based on this, a heating control unit that controls heating of the food placed in the heating chamber, a moving direction determining unit that determines the moving direction of the food in the heating chamber, and a reading that controls the reading operation of the reading device. The reading control unit includes a control unit, and after the movement direction determination unit determines that the movement direction of the food is the direction out of the heating chamber, the reading device determines the information code of the information code for a predetermined time. When the reading operation is stopped or the moving direction determination unit determines that the moving direction of the food is the direction out of the heating chamber, the information code read by the reading device is canceled at a predetermined time. It is a feature.

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

The information code is used to cook food. For example, the information code includes information indicating the type of food and information indicating the conditions for cooking the food indicating the type (heating information). The heating information is information necessary for cooking, and includes the heating time in the cooking device 1 and the wattage of the high frequency output. The information code was specifically shown with information indicating the type of food, such as the type of food (or even the type of bento), or the type of rice ball (or even the type of rice ball). Includes heating time according to food, heating information including wattage of high frequency output. This information code is affixed to food or food containers, for example by printing or sealing. Since the information code is used for cooking the specified food, it includes only the information for specifying the food, and the heating information for the specified food is acquired from the external server 51 (FIG. 8). May be good. Further, the information code may include only the heating information of the food.

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

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

As shown in FIG. 7, the control unit 22 includes an operation panel 11, a heating operation unit 23, a reading device 16, a reading area lighting unit 21, a reading result notification unit 24, a front door open / close detection unit 25, and a memory (storage unit). 52 is connected. The front door open / close 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 the closed state of the front door 12.

The heating operation unit 23 is an operation unit for heating food arranged 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 voice generation 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 type 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 heats the heating operation unit 23 so that the food is heated according to the acquired heating information. Control. The cooking device 1 itself may have heating information according to the type of food. In this case, the cooking cooker 1 does not need to communicate with the server 51.

Further, the control unit 22 is a heating operation unit 23 based on the determination results of the determination unit 22a (movement direction determination unit) for determining the movement direction (insertion direction or take-out direction) of the food 40 in the heating chamber 13 and the determination unit 22a. It includes a heating control unit 22b that controls the heating operation of the above, and a reading control unit 22c that controls the reading operation of the reading device 16 based on the determination result of the determination unit 22a.

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

The determination unit 22a determines the moving direction of the food 40 in 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, it is assumed that, of the two received images, the image of the first received food (QR code) 40 is designated by reference numeral 40a, and the image of the next received food (QR code) 40 is designated by reference numeral 40b. As shown by reference numeral 1181 in FIG. 8, if the image 40a is outside the refrigerator 13 with respect to the image 40b, the moving direction of the food (QR code) 40 is inside the heater 13 (direction of arrow X). Is determined to be. On the other hand, as shown by reference numeral 1182 in FIG. 8, if the image 40a is inside the heating cabinet 13 with respect to the image 40b, the moving direction of the food 40 (QR code) is the outside of the heating cabinet 13 (arrow Y). Direction). 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). The moving direction of the food 40 may be determined from the image of.

The heating control unit 22b permits the heating operation by the heating operation unit 23 if the determination result of the determination unit 22a indicates that the food 40 has moved to the inside of the heating chamber 13, that is, the inside of the storage. 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 refrigerator, the heating operation by the heating operation unit 23 is not permitted.

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

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

It is preferable that the start of the predetermined time is when the determination unit 22a determines that the moving direction of the food 40 in the heating chamber 13 is the direction toward the outside of the chamber 13. In this case, since the reading operation by the reading device 16 is stopped after the food 40 moves to the outside of the refrigerator, even if the food 40 taken out from the heating chamber 13 passes through the reading position of the reading device 16. , There is almost no risk 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 open / close detection unit 25 detects that the front door 12 has been closed. Specifically, the front door open / close detection unit 25 detects that the front door 12 has been opened, and the determination unit 22a determines that the moving direction of the food 40 in the heating chamber 13 is toward the outside of the chamber 13. After the determination, the reading operation by the reading device 16 is stopped after a predetermined time, or after the time when the reading operation by the reading device 16 is stopped and the door open / close detection unit 25 detects that the front door 12 is closed. To release. In this case, since it is necessary to open the front door 12 in order to take out the cooked food 40 from the heating chamber 13, the food 40 is taken out from the heating chamber 13 with the front door 12 opened. .. At this time, the reading operation by the reading device 16 is started to be stopped. Then, after a predetermined time elapses or when the front door 12 is closed, the stop of the reading operation by the reading device 16 is released. As a result, the information code of the food 40 can be read by the reading device 16 when the front door 12 is opened for cooking the food 40 and the food 40 is to be put into the heating chamber 13.

The memory 52 stores the heating information included in the information code read by the reading device 16. As a result, for the food whose information code has been read once, the heating information is registered in the memory 52 of the cooking device 1, so that it is not necessary to acquire the heating information each time the information code is read from the outside of the cooking device 1.

(Operation of cooking cooker 1)
In the above configuration, the operation of the cooking device 1 will be described below. Here, a case where the food 40 is a bento with an information code attached to the upper surface of the container and the bento is heated by the cooking cooker 1 will be described.

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"). Then, the user opens the front door 12 according to the guidance display 20. When the front door open / close detection unit 25 detects the open state of the front door 12, the control unit 22 operates the reading device 16 and the reading area lighting unit 21.

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

By this operation, the reading device 16 reads the information code attached to the lunch box. When the reading device 16 succeeds in reading the information code, the control unit 22 notifies the user of the reading result by the reading result notification unit 24. In this case, the operation of the reading result notification unit 24 is, for example, an operation of emitting a continuous sound of "pee", an operation of emitting a voice of "successful reading of the information code", or both of them.

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

When the information code is successfully read, the control unit 22 communicates with the server 51 and acquires heating information according to the type of food indicated by the information code from the server 51. After that, the control unit 22 closes the front door 12, presses the start button of the operation panel 11, and heats the lunch box in the heating chamber 13 according to the acquired heating information.

After that, in the control unit 22, the user closes the front door 12, the heating change button 11a of the operation panel 11 is operated, and the start button is pressed. Then, as the start button is pressed, the lunch box in the heating chamber 13 is heated according to the acquired heating information.

On the other hand, when the reading device 16 fails to read the information code, the control unit 22 notifies the user of the reading result by the reading result notification unit 24. The operation of the reading result notification unit 24 in this case is, for example, an operation of emitting an intermittent sound of "pip, pip, pip", an operation of emitting a voice of "Failed to read the information code", or both of them.

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

As described above, when the warming of the lunch box is completed, the user is notified to that effect, and the user takes out the lunch box from the heating chamber 13. By taking out the lunch box from the inside of the heating chamber 13, the determination unit 22a of the control unit 22 determines that the moving direction of the lunch box is the outside of the heating chamber 13. Based on the determination result of the determination unit 22a (the moving direction of the lunch box is the outside of the heating chamber 13), the heating control unit 22b does not allow the heating operation by the heating operation unit 23. Further, based on the determination result of the determination unit 22a (the moving direction of the lunch box is the outside of 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 time.

(effect)
According to the cooking device 1 having the above configuration, when the determination unit 22a determines that the moving direction of the food 40 is the direction out of the heating chamber 13, the reading control unit 22c uses the information code by the reading device 16 for a predetermined time. Stops the reading operation of, or cancels the information code read by the reading device 16 at a predetermined time. As a result, the information code is not read by the reading device 16 for a predetermined time in a state where the food 40 is not present in the heating chamber 13, or the information code read by the reading device 16 is canceled at a predetermined time. The heating operation (no load operation) by the operating unit 23 is also not performed. Therefore, the cooking cooker 1 can suppress no-load operation.

Further, according to the cooking device 1 having the above configuration, the determination unit 22a can easily determine the moving direction of the food 40 by the image pickup analysis by the camera 31.

Further, according to the cooking cooker 1 having the above configuration, after a predetermined time elapses, the stop of the reading operation of the reading device 16 is released, or the operation of canceling the information code read by the reading device 16 is released. Therefore, it is possible to read the information code of the food 40 to be cooked next. Here, the predetermined time may be set arbitrarily, and at least the time until the food is completely taken out from the heating chamber and the reading position by the reading device is passed may be set. By setting the predetermined time in this way, it is possible to further reduce the possibility that the information code is read again by the reading device 16 when the food after heating is taken out from the heating chamber 13.

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

(Outline of cooking cooker 2)
As shown in FIGS. 9 and 10, the cooking cooker 2 according to the present embodiment includes a motion sensor 41 (movement detection unit) for detecting the movement of the food 40 instead of the camera 31 of the cooking cooker 1. Further, the determination unit 22a (movement direction determination unit) of the control device according to the present embodiment is based on the order of reading the information code by the reading device 16 and detecting the movement of the food 40 by the motion sensor 41. The moving direction of the food 40 in 13 is determined. Other configurations of the cooking device 2 are the same as those of the cooking device 1.

(Motion sensor 41)
As shown by reference numeral 1101 in FIG. 10, the motion sensor 41 is provided at the lower part inside 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 way, the influence of heat on the motion sensor 41 can be reduced. The position where the motion sensor 41 is provided is not limited to such a configuration, and may be any position where the movement of the food 40 can be detected.

Further, as shown by reference numeral 1102 in FIG. 10, the movement detection position 41a of the food 40 by the motion sensor 41 is on the inner side of the heating chamber 13 with respect to the information code reading position 16a. For example, the motion sensor 41 is tilted inward so that the detection position 41a is inside the heating chamber 13, and is installed on the control frame 15. Further, the reading device 16 is installed on the control frame 15 so as to be tilted outward so that the reading position 16a is outside the heating chamber 13. As a result, the detection position 41a can be surely located on the inner side of the heating chamber 13 with respect to the reading position 16a.

(Control device)
The determination unit 22a determines the movement direction of the food 40 in the heating chamber 13 based on the order of reading the information code by the reading device 16 and detecting the movement of the food 40 by the motion sensor 41. Here, as shown by reference numeral 1102 in FIG. 10, the detection position 41a is on the inner side of the heating chamber 13 with respect to the reading position 16a. Therefore, when the motion 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 movement direction of the food 40 is the storage of the heating storage 13. It is determined that it is inside (in the direction of arrow X). On the other hand, when the motion 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 the storage of the heating storage 13. It is determined that it is on the outside (direction of arrow Y).

(effect)
According to the cooking device 2 having the above configuration, the determination unit 22a easily determines the movement direction of the food 40 by the order of reading the information code by the reading device 16 and detecting the movement of the food 40 by the motion sensor 41. Can be done.

Further, since the detection position 41a is on the inner side of the heating chamber 13 with respect to 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 through the reading position 16a. Is done. Therefore, the read control unit 22c can stop the reading operation by the reading device 16 before the food 40 passes through the reading position 16a, or reliably cancels the information code read by the reading device 16. Can be done. Therefore, the cooking cooker 2 can surely suppress the no-load operation.

(Modification example)
In the cooking utensil 2, the movement detection position 41a of the food 40 by the motion sensor 41 may be on the outside side of the heating chamber 13 from the reading position 16a of the information code. At this time, if the motion 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 the heating cabinet 13. It is determined that it is inside the refrigerator. On the other hand, when the motion 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 movement direction of the food 40 is the storage of the heating storage 13. Judged to be outside.

When the determination 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. As a result, even after the determination unit 22a determines the moving direction of the food 40 after the food 40 has passed the reading position 16a, the reading control unit 22c cancels the information code read by the reading device 16. Can be done. Therefore, the cooking cooker 2 can suppress the no-load operation.

[Example of implementation by software]
The control block of the control unit 22 (particularly the determination unit 22a, the heating control unit 22b, and the read control unit 22c) may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or software. 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 realizes each function. This computer includes, for example, at least one processor (control device) and at least one computer-readable recording medium in which the program is stored. Then, 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, a "non-temporary tangible medium", for example, a ROM (Read Only Memory) or the like, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. Further, a RAM (Random Access Memory) for expanding the above program may be further provided. Further, the program may be supplied to the computer via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. It should be noted 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 above program is embodied by electronic transmission.

〔summary〕
The heating cooker according to the first aspect of the present invention is arranged in the heating chamber based on a heating chamber, a reading device for reading an information code for cooking food, and an information code read by the reading device. The reading includes a heating control unit that controls heating of the food, a movement direction determination unit that determines the movement direction of the food in the heating chamber, and a reading control unit that controls the reading operation of the reading device. After the movement direction determination unit determines that the movement direction of the food is the direction out of the heating chamber, the control unit stops the reading operation of the information code by the reading device for a predetermined time, or the control unit stops the reading operation of the information code.
