FIG. 4 is a longitudinal sectional view of the control frame 15 showing the installed state of the reader 16. As shown in FIG. FIG. 5 is an explanatory diagram showing the reading area 19 of the reading device 16. As shown in FIG.

As shown in FIG. 4 , the control frame 15 is provided to protrude forward from the heating cooker 1 . The reader 16 is attached to the lower surface of the reader board (circuit board) 17 and is provided inside the control frame 15 at the bottom. The reader board 17 contains the driver circuitry for the reader 16 . That is, the reader 16 is installed outside the heating chamber 13 and above the front opening 13b of the heating chamber 13, and has a reading area 19 below the installation position.

The reading device 16 is, for example, a bar code reader, and reads an information code (for example, a bar code) attached to the food to be heated by the heating cooker 1 or the food container.

The reader 16 has a reading area 19 below the reader 16, as shown in FIG. are doing.

A reading area 19 of the reader 16 is illuminated by a reading area illuminator (not shown) so that the user can visually recognize the reading area 19 with, for example, red light. Note that the light indicating the reading area 19 is not limited to red, and may be other light visible to the user.

2 and 3, the reading device 16 is provided at the center of the front opening 13b of the heating chamber 13 in the width direction (horizontal direction).

(information code)
FIG. 6(a) is an explanatory diagram showing an example of an information code made up of a two-dimensional code, and FIG. 6(b) is an explanatory diagram showing an example of an information code made up of a one-dimensional bar code. FIG. 7(a) is an explanatory diagram showing an example of guidance display on the operation panel 11 for reading the information code by the reading device 16, and FIG. 7(b) is for reading the information code by the reading device 16. 11 is an explanatory diagram showing another guidance display example on the operation panel 11 of FIG.

The information code includes at least heating information or information for obtaining the heating information. The heating information includes the magnitude of the high-frequency output and the heating time when the heating cooker 1 is a microwave oven. When the heating information is directly included in the information code, the heating cooker 1 can acquire the heating information by reading the information code. When the information for acquiring the heating information is included, the heating cooker 1 uses the information to connect the heating cooker 1 itself or the heating cooker 1 to the server 31, which will be described later, through an Internet line or the like. (Refer to FIG. 8) to acquire heating information.

Information for obtaining heating information includes, for example, information indicating the type of food. The information indicating the type of food is, for example, information indicating that the food is lunch (or the type of lunch) or rice ball (or the type of rice ball). The information for acquiring the heating information may be information on the memory number of the heating cooker 1 or the server 31 in which the heating information is stored. In this embodiment, the server 31 has the heating information, and the configuration for acquiring the heating information using the information indicating the type of food will be exemplified.

The information code may also include information such as the product code of the food and the expiration date. Such an information code is attached to the food or food container, for example, by printing or sealing.

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 is not particularly limited to a bar code or the like as long as it can indicate heating information or the type of food.

The operation panel 11 displays guidance for the user so that the reader 16 can read the information code smoothly. For example, in the example of (a) of FIG. 7, a guidance display 20 saying "Please open the door and hold the information code over the red light" is displayed. Further, in the example of FIG. 7(b), a guide display 20 saying "Please open the door and illuminate the information code with red light" is displayed. It should be noted that these guide displays 20 are examples, and are not particularly limited to these.

(Control device)
FIG. 8 is a block diagram showing the configuration of a control device provided in the heating cooker 1. As shown in FIG. The control device includes a control section 22 that controls the operation of the heating cooker 1 . The control unit 22 is composed of, for example, a microcomputer and has a CPU, a ROM and a RAM.

As shown in FIG. 8, the control unit 22 is connected to the operation panel 11, the heating operation unit 23, the reader 16, the read result notification unit 24, and the front door open/close detection unit 25. FIG. The front door open/close detector 25 is composed of a switch that outputs an ON signal when the front door 12 is open, and outputs an OFF signal when the front door 12 is closed. and closed state.

The heating operation unit 23 is an operation unit that heats food placed in the heating chamber 13, and is a microwave output device when the heating cooker 1 is a microwave oven. The read result notification unit 24 is a buzzer or voice generation unit, and is controlled by the control unit 22 to notify the user of the success or failure of the reading of the information code by the reading device 16 . Instead of the reading result notification unit 24 that notifies the reading result by sound, the operation panel 11 may be used as a notification unit that notifies the reading result by display. Moreover, it is also possible to adopt a configuration in which the result of reading is notified both by sound and by display.

The control unit 22 can communicate with the server 31 using, for example, an Internet line. In the server 31, heating information corresponding to the types of various foods is registered. The control unit 22 acquires heating information from the server 31 using information (for example, information indicating the type of food) acquired by the reading device 16 reading the information code, and the food is heated according to the acquired heating information. Thus, the heating operation unit 23 is controlled.

Further, the control section 22 controls the operation of the reading result notification section 24 to notify the user of the success or failure of the reading of the information code by the reading device 16 . Based on the information included in the information code, the control unit 22 determines that the reading is successful when the heating information can be obtained from the server 31 . Based on the information contained in the information code, the control unit 22 determines that reading has failed when the heating information cannot be obtained from the server 31 . For this reading failure, even if the information code is appropriate, the reading method is bad and it cannot be read, or the information code itself is not for acquiring the heating information, and the heating information is acquired from the server 31. It also includes cases where information for the purpose was not included.

Further, the control unit 22 controls the operation of the reader 16 and determines whether or not to perform reading by the reader 16 according to the open/closed state of the front door 12 . More specifically, the controller 22 controls the reading device 16 to read when the front door 12 is open, and not to read when the front door 12 is closed. to control the reader 16. In addition, the control unit 22 reads the information code even when the front door 12 is open according to the elapsed time after the front door 12 is opened, the elapsed time after the reading device 16 reads the information code, and the like. For example, the operation of the device 16 is stopped. Details will be described later with reference to the flowchart of FIG.

(Operation of heating cooker 1)
The operation of the heating cooker 1 in the above configuration will be described. Here, a case will be described in which a boxed lunch having an information code attached to the upper surface of the container is heated by the heating cooker 1 .

When the user opens the front door 12 and the front door open/close detector 25 detects this state, the controller 22 causes the reader 16 to operate. As a result, the reading device 16 starts to emit, for example, red light, and the user can know at a glance that it is in a reading state.

Next, the user follows the guide display 20 on the operation panel 11 to move the lunch so that the information code enters the reading area 19 of the reader 16 (so that the information code is illuminated with red light).

By this operation, the reader 16 reads the information code attached to the lunch. When the information code is successfully read by the reading device 16, the control section 22 causes the reading result notification section 24 to notify the user of the reading result. In this case, the operation of the reading result notification unit 24 is, for example, an operation of emitting a continuous sound of "beep", an operation of emitting a voice saying "the information code has been read successfully", or both.

When the reading result notification unit 24 informs the user that the information code has been successfully read, the user places the box lunch inside the heating chamber 13 , closes the front door 12 , and presses the start button on the operation panel 11 .

When the information code is successfully read, the control unit 22 communicates with the server 31 and acquires from the server 31 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 box lunch in the heating chamber 13 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. In this case, the operation of the reading result notification unit 24 is, for example, an operation of emitting an intermittent sound of "beep, beep, beep", an operation of emitting a voice saying "reading of information code failed", or both.

When the reading result notification unit 24 informs the user that the reading of the information code has failed, the user again puts the information code into the reading area 19 of the reading device 16 (so that the information code is illuminated with red light). , move the bento. As a result, the operation when the reading of the information code is successful is as described above.

(Reading operation of the information code of the heating cooker 1)
Next, the reading operation of the information code of the heating cooker 1 will be described with reference to the flow chart of FIG. FIG. 9 is a flow chart showing the information code reading operation of the heating cooker 1 .

The control unit 22 determines whether or not the open state of the front door 12 has been detected (S1). It is determined whether or not there is (S2). If it is determined that the open state is not detected for the first time after the start of heating, reading by the reader 16 is started (S3).

On the other hand, in S2, when it is determined that the open state is detected for the first time after the start of heating, the control unit 22 waits for the first time (first predetermined time) after the front door 12 is opened ( S11), after the first time has elapsed, the process proceeds to S3, and reading by the reading device 16 is started (S3).

Here, the reason why S11 is provided is to avoid a useless operation such as reading the information code when taking out the heat-treated boxed lunch from the heating chamber 13 and setting the heating information again. Such useless operations can be avoided by not performing reading for the first time when the open state of the front door 12 is detected for the first time after the start of heating. The first time for delaying the start of reading is preferably set according to the time required to take out the box lunch from the heating chamber 13, and is, for example, about 2 to 3 seconds.

During the reading operation, the control unit 22 determines whether or not the information code is read (S4). If the information code is read, the reading is temporarily stopped, and a second time (fifth predetermined time) elapses from the time when the information code is read. Reading is resumed later (S5). Further, the control unit 22 analyzes the read contents (S6), and if the heating information can be acquired from the server 31, determines that it is valid and sets the heating information in a predetermined write area of the RAM (S7). , the reading result is notified (S8). After that, the control unit 22 proceeds to S9. Also, if it is determined in S4 that the information code has not been read, the process proceeds to S9 without going through the processes of S5 to S8.

In S9, it is determined whether or not the closed state of the front door 12 has been detected, and if it is determined that the closed state has not been detected, the process returns to S4. On the other hand, if it is determined in S9 that the closed state has been detected, reading by the reader 16 is stopped (S10), and the process returns to S1.

Here, the reason why S5 is provided is to avoid repeating S4 to S9 each time the same information code is read multiple times when the action of putting the boxed lunch into the heating chamber 13 is slow. be. Repeated notification of results from the reading result notification unit 24 is unavoidably annoying. The second time for temporarily stopping reading is preferably set according to the time required for the read information code to pass through the reading area 19 of the reading device 16, and is, for example, about 1 second. In addition, in the flowchart of FIG. 9, S6 to S8 are described after S5 for convenience, but S5 and S6 to S8 may be performed in parallel.

Further, here, after notifying the reading result in S8, unless it is determined in S9 that the front door 12 is closed, the process returns to S4 to enable resetting of the heating information in S7. As a result, until the front door 12 is closed, the information code can be read again and the heating information can be set again any number of times without requiring a special cancellation operation or the like.

(Advantages of heating cooker 1)
In the heating cooker 1, the controller 22 determines the operation of the reader 16 according to the open/close state of the front door 12, so the reader 16 can be turned on and off appropriately without bothering the user. That is, the user can start reading by the reader 16 only by opening the front door 12 and can stop reading by the reader 16 only by closing the front door 12 . Since the opening and closing operation of the front door 12 is an essential operation for heating food in the heating cooker 1, by interlocking with such an essential operation, the switch for turning on and off the reader 16 is operated. Usability is improved compared to the configuration in which Moreover, power consumption can be reduced compared to a configuration in which the reading device 16 is always performing reading operations.

Also, when the open state of the front door 12 is detected for the first time after the start of heating, reading is not performed for the first time. can be avoided.

Moreover, once the information code is read, reading is not performed for the second time after that, so it is possible to avoid unnecessary operations such as reading the same information code multiple times and setting the heating information.

In addition, in the configuration described in Patent Document 1, the user must manually operate the barcode scanner to read the barcode marked on the container of the food, and the barcode reading operation is troublesome. In addition, in the configuration described in Patent Document 2, when reading a barcode with the first barcode reader, the barcode marked on the food container is provided on the vertical surface of the first barcode reader. It is necessary to hold the device over the device, and the barcode reading operation is similarly troublesome. In particular, in the case of bento, it is necessary to tilt the bento, which is inconvenient. Further, when the barcode is read by the second barcode reader, no particular user operation is required. The detection signal passing surface is easily soiled by the steam generated from the food and the scattered objects from the food. In addition, since the heating chamber reaches a high temperature, deterioration due to temperature is likely to occur.

On the other hand, in the heating cooker 1, the reading device 16 is installed outside the heating chamber 13 and above the front opening 13b of the heating chamber 13, and has a reading area 19 below the installation position. is provided in

Therefore, the information code can be read by the reader 16 while the user is placing the food to be heated on the heating chamber 13 . This eliminates the need for the user to perform an independent operation for causing the reading device 16 to read the information code, thus facilitating the work of reading the information code.

In addition, since the reading device 16 is installed above the front opening 13b of the heating chamber 13, the detection signal passing surface (the lower surface of the reading window 18) is less likely to become dirty, and the temperature inside the heating chamber 13 does not change. less susceptible to influence.

A control frame 15 for housing the control board of the operation panel 11 is provided in a projecting shape above the front opening 13b of the heating chamber 13 . The reader 16 is provided so as to face downward from the lower surface of the control frame 15 . Thus, the reader 16 is installed using the control frame 15 that accommodates the control board of the operation panel 11 .

[Embodiment 2]
Other embodiments of the invention are described below. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

The appearance and configuration of the heating cooker 1A of Embodiment 2 are the same as those of the heating cooker 1 of Embodiment 1, and the information code reading operation procedure is partially different. FIG. 10 is a flow chart showing the information code reading operation of the heating cooker 1A of the second embodiment.

As shown in FIG. 10, at S9 in the flowchart of FIG. 9, it is determined that the closed state of the front door 12 is not detected, and S21 is provided before returning to S4. In S21, the control unit 22 determines whether or not a third time (second predetermined time, third predetermined time) has passed without reading by the reading device 16 or not. When the control unit 22 determines that the third time has not passed, the process returns to S4. On the other hand, if it is determined in S21 that the third time has passed without reading, the reading is stopped (S22). Thereafter, the control unit 22 repeatedly determines whether or not the front door 12 is open (S23), and returns to S1 when determining that it is not open. After setting the heating information in S7 and returning to S1, the control unit 22 starts heating by the heating operation unit 23 when the start button is pressed.

That is, in the heating cooker 1A of Embodiment 2, when the third time elapses without reading, the reading by the reading device 16 is stopped even if the front door 12 is open. In this case, if the reading device 16 has not read the information code even once, the point at which the open state of the front door 12 is detected in S1 becomes the starting point of the third time. On the other hand, if the reading device 16 has read the information code even once, the starting point of the third time is the time when it is determined that the information code was last read in S4. Note that the third time until reading is stopped is, for example, about 30 seconds.

(Advantages of heating cooker 1A)
By adopting such a configuration, when the front door 12 is left open, it is possible to avoid the problem that the reading device 16 wastefully continues the reading operation and power is wasted. .

[Embodiment 3]
Other embodiments of the invention are described below. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

The appearance and configuration of the heating cooker 1B of Embodiment 3 are the same as those of the heating cookers 1 and 1A of Embodiments 1 and 2, and the information code reading operation procedure is partially different. FIG. 11 is a flow chart showing the information code reading operation of the heating cooker 1B of the third embodiment.

In the flowchart of FIG. 10, in S23, the controller 22 repeatedly determines whether the front door 12 is open until the front door 12 is closed. S24 is provided to proceed when it is determined that is in the open state. In S24, the control unit 22 determines whether or not a predetermined operation for restarting reading by the reading device 16 has been performed. When the controller 22 determines in S24 that the predetermined operation for resuming reading has been performed, the process proceeds to S3 and the reading by the reader 16 is resumed. On the other hand, if it is determined in S24 that the predetermined operation for restarting reading has not been performed, the process returns to S23. The controller 22 repeats S23 and S24 until it determines in S23 that the front door 12 is closed.

The predetermined operation for restarting reading in S24 is, for example, an operation of pressing a predetermined button or an arbitrary button on the operation panel 11 .

In S21, if the third time elapses without reading, the reading by the reading device 16 is stopped in S22. The starting point of the fourth predetermined time) is the time when a predetermined operation for restarting is performed. Note that when it is determined that the information code has been read after the restart, that time point may be set as a new starting point.

(Advantages of heating cooker 1B)
With such a configuration, even when the reading device 16 is stopped while the front door 12 is open, the buttons on the operation panel 11 can be operated without closing the front door 12 once and opening it again. Reading can be restarted by a simple operation such as Therefore, usability is further improved.

[Embodiment 4]
Other embodiments of the invention are described below. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and description thereof will not be repeated.

The appearance and configuration of the heating cooker 1C of Embodiment 4 are the same as those of the heating cookers 1, 1A, and 1B of Embodiments 1, 2, and 3, and the information code reading operation procedure is partially different. FIG. 12 is a flow chart showing the information code reading operation of the heating cooker 1C of the fourth embodiment.

As shown in FIG. 12, when it is determined in S23 that the front door 12 is not in the open state (that is, the front door 12 is in the closed state), and in S9 and S10 it is determined that the front door 12 is in the closed state. If so, the process proceeds to S31. In S31, it is determined whether or not a fourth time (sixth predetermined time) has elapsed without the start key being pressed. When it is determined in S31 that the fourth time has passed, the set heating information is canceled (S32) and the process returns to S1. On the other hand, if it is determined that the fourth time has not elapsed, it is determined whether the start key has been pressed (S33), and if it is determined that the start key has been pressed, the process returns to S1.

(Advantages of heating cooker 1C)
With such a configuration, even if the heating information is set and the front door 12 is closed, if the start key is not pressed, the set heating information is canceled and the heating cooker 1C is initialized. You can go back to standby. As a result, it is possible to prevent a mistake in which a boxed lunch left without pressing the start key is heated and served without paying any attention. This further improves usability.

In the first to fourth embodiments described above, the first to fourth times are fixed, but the user may be allowed to set them using the operation panel 11 or the like as appropriate. In the second to fourth embodiments, the waiting time until the operation of the reading device 16 is stopped even when the front door 12 is open is set to the third time. (second predetermined time), when reading is performed once (third predetermined time), and when reading is resumed after a predetermined operation is performed (fourth predetermined time). You may
