Description

  The present invention relates to a heating cooker having heating means by induction heating, and more specifically to a heating cooker that can notify the end of heating, an alarm, and the like by voice.

A cooking device having a heating means by induction heating applies a high frequency voltage to the induction heating means with a built-in coil, and the eddy current generated in the cooking pan made of a ferromagnetic material by the generated high frequency magnetic field causes the food in the container to move. It is a cooking device that heats (see, for example, Patent Document 1).
A heating cooker having induction heating means has been proposed in which a message is notified by voice when an erroneous operation or abnormality occurs to alert the user (for example, see Patent Document 2).

JP 2005-56722 A JP 2006-4630 A

The coil of the induction heating means is disposed on the lower side of the top plate on which the cooking pan is placed, and the operating state of the heating means cannot be directly visually confirmed like a gas appliance.
For this reason, an induction heating cooker has been proposed that informs the user that the heating has been completed by voice after the operation of the heating means has been completed. In some cases, the end of heating could not be confirmed.
In addition, in this case, the top plate is hot for a while after the operation of the heating means is finished, but the user cannot directly visually confirm that the top plate is hot. In addition, it is necessary to prevent the user from touching the top plate.
If the top plate is hot, it may be possible to send a message to that effect. However, even in such a case, the notification of only the message makes it easier for the user to pay attention to the fact that cooking has been completed. There is a risk that a message indicating that the temperature is high will be missed or that attention to the message may be lost.

  An object of the present invention is to provide a cooking device capable of notifying the end of operation of the heating means and reliably transmitting to the user that the top plate is hot.

In order to solve the above problems, the heating cooker of the present invention is
A heating means that is arranged under the top plate on the top surface of the main body and induction-heats the cooking pan placed on the top plate;
Temperature measuring means for measuring the temperature of the cooking pan through the top plate;
Operation means for outputting operation information such as heating conditions and heating start and stop of the heating means operated by the user,
Control means for controlling the heating means based on the operation information output from the operation means;
In a heating cooker comprising
The control means includes a first storage unit storing first notification data for voice notification of the end of operation of the heating means, and a second notification for voice notification of an alarm indicating that the top plate is at a high temperature. A second storage unit storing data, a third storage unit storing third notification data composed of music or melody, voice melody notification means for performing notification based on the notification data,
Have
After the operation of the heating means is completed, the first notification data stored in the first storage unit is notified by voice from the voice melody notification means,
When the temperature measured by the temperature measuring unit at the end of the operation of the heating unit is equal to or higher than a predetermined temperature, after the second notification data stored in the second storage unit is notified by voice from the voice melody notification unit,
Further, the third notification data stored in the third storage unit is notified of music or melody from the voice melody notification means.

The operating means has a standby mode switching part for shifting the heating means to the heating standby mode or canceling the heating standby mode,
The control means enables the operation of the heating means based on the operation information of the operation means only when the standby mode switching unit is shifted to the heating standby mode, and
When the heating standby mode is canceled by the operation of the standby mode switching unit after the operation of the heating unit is finished, if the temperature measured by the temperature measuring unit is equal to or higher than a predetermined temperature, the second notification data stored in the second storage unit is stored. It is desirable to notify the voice again from the voice melody notification means.

  The control means, when the third notification data stored in the third storage unit is being informed of music or melody from the voice melody notification means, when the heating standby mode is canceled by the standby mode switching unit, the music or melody It is desirable to stop the notification and end the notification.

Further comprising a data communication means capable of data communication with an external device,
The control means receives at least one of the first notification data, the second notification data, and the third notification data via the data communication means, and stores the at least one of the corresponding first storage unit to third storage unit. It is desirable to store.
Data communication can exemplify infrared communication.

A plurality of heating means are provided,
The third storage unit can store a plurality of third notification data,
It is desirable that the control means stores different third notification data corresponding to each heating means in the third storage unit, and makes the music or melody notification in the voice melody notification means different for each heating means.

  It is desirable that the control means does not receive data by the data communication means when any of the plurality of heating means is in operation.

By outputting the first notification data from the voice melody notification unit after the operation of the heating unit is completed, the user is notified of the end of the operation of the heating unit. At this time, if the temperature measured by the temperature measuring means is abnormal at a predetermined temperature, the second notification data is output following the first notification data.
In the present invention, following the notification data, the user has missed the first notification data and the second notification data by outputting music or melody as third notification data from the voice melody notification means. However, attention is paid to the third voice notification data composed of music or melody to be listened to. Therefore, the end of operation of the heating means can be reliably transmitted from the user's hearing.
Note that the third notification data has a certain length of time (several tens of seconds to several minutes) such as music and melody, so that cooking is completed even when there is no user near the cooking device at the end of heating. Can be transmitted to the user.
In addition, after the third notification data is output, if the top plate is hot, the second notification data notifies that fact again, so the user accidentally touches the high temperature top plate. The problem can be solved.

  When the heating standby mode in which the heating means can be operated is canceled by a user's operation, if the temperature measured by the temperature measuring means is equal to or higher than a predetermined temperature, the second notification data is sent from the voice melody notification means. Since the notification is made again, the user does not miss the second notification data and can solve the problem of accidentally touching the high temperature top plate.

  In addition, the first to third notification data can be received and stored in the corresponding storage unit by data communication means capable of data communication with an external device, so that the message, music, melody desired by the user can be obtained. Or the like can be output as notification data after heating by the heating means. By outputting the voice desired by the user, there is an advantage that the user's attention can be attracted as compared with the case where a preset message is output.

  Further, when there are a plurality of heating means, the third notification data is changed for each heating means, so that it can be confirmed by hearing which heating means has ended and is at a high temperature.

  Furthermore, when any of the heating means is in operation, the data communication means does not receive data, thereby preventing malfunction of the heating cooker and distraction of the user during cooking.

  FIG. 1 is a perspective view showing an example of a built-in type heating cooker (10) to which the present invention can be applied. FIG. 2 is a control block diagram of the cooking device (10) of the present invention.

  The heating cooker (10) has a top plate frame (14) on the upper surface of the main body (12), and a ceramic top plate (16) is disposed on the top plate frame (14).

An upper operation panel (22) is provided at the front end of the top plate frame (14). The upper operation panel (22) constitutes operation means (20) for the user to control the heating cooker (10) together with a pre-operation panel (24) described later. The upper operation panel (22) is provided with a plurality of operation buttons (23), and the user can adjust the output without stirring forward while stirring in the cooking pan. it can.
At the rear end of the top frame (14), an intake port and an exhaust port are formed to prevent temperature rise inside the main body (12). Fans are arranged. The intake port and the exhaust port are covered with covers (18) and (19) having punched holes.

On the top plate (16), the round frame part indicated by reference numerals (30) and (31) is a heating part for placing the cooking pan for induction heating, and the round frame part indicated by reference numeral (32) at the rear is It is a heating part which mounts the cooking pan incompatible with induction heating. Below the induction heating section (30) (31), heating means (35) (36) consisting of a heating coil that twists a litz wire and winds it in a spiral shape to generate magnetic flux is provided. Under the non-corresponding heating part (32), a radiant heater for radiatively heating the cooking pan is provided as a heating means (37). The heating means (35) and (36) inductively heat the cooking pot with the magnetic flux generated from the heating coil.
In the center of the front part of the top plate (16), a display part (28) for displaying the operating state and the like of the heating cooker (10) is formed.

The main body (12) is provided with a front operation panel (24) on the front right side. As shown in FIG. 1, the front operation panel (24) has a dial-type operation for adjusting the power switch (21) of the heating cooker (10) and the heating means (35) and (36), and the output. Sections (25) and (25), other operation buttons (26), and an operation button (27) for voice downloading.
The operation units (25) and (25) can be moved in and out from the front operation panel (24). It also serves as a standby mode switching unit.
The pre-operation panel (24) is transmitted from a speaker (49) connected to a voice melody notification means (48) described later and an external device such as a portable terminal device (90) such as a mobile phone or PHS. An infrared light receiving unit (46) for receiving an infrared signal is provided.

  The main body (12) has a roaster portion (33) formed on the left side of the front surface. In the cooking chamber of the roaster section (33), a sheathed heater is projected as a heating means (38), and a grill is placed on a drawer type tray, and the food is heated by the heating means (38). The cooking chamber communicates with an exhaust port provided at the rear end of the top plate frame (14), and is forcedly exhausted while being smoked and deodorized by a catalyst and a fan containing smoke and odor in the cooking cabinet. The catalyst can be exemplified by a platinum catalyst, and it is desirable to heat the catalyst with a heater in order to enhance the catalyst performance.

  In order to measure the temperature of the cooking pan placed on the heating means (35) (36) via the top plate (16), the temperature measuring means respectively for the heating means (35) (36) by induction heating (39) (39) are arranged. The temperature measuring means (39) and (39) are in contact with the back surface of the top plate (16) at each of two locations, the center of the heating means (35) and (36), and a position approximately 1/2 of the radius from the center. It is arranged as follows.

  All the control of the heating cooker (10) having the above-described configuration is performed by the control means (40) disposed at a proper position inside the main body (12). Specifically, as shown in FIG. 2, the control means (40) includes heating means (35) (36) (37) (38), temperature measurement means (39), operation means (20), voice melody. The notification means (48), the infrared light receiving section (46) and the display section (28) are electrically connected, and operate upon receiving power supply from a power source (not shown).

The control means (40) has a storage unit (42) that stores programs such as various control programs and cooking programs related to the heating cooker (10). Examples of the cooking program include an automatic cooking program, a timer cooking program, and a manual cooking program as described below.
The storage unit (42) includes first to third storage units (43), (44), and (45) that store the following notification data.

The first storage unit (43) stores first notification data for voice notification of the end of operation of the heating means (35) and (36). As the first notification data, for example, a message “Heating has been completed” can be exemplified. The first notification data is preferably a message for a relatively short time (about 2 to 5 seconds) in order to transmit the fact of the operation completion to the user.
The second storage unit (44) stores second notification data for voice notification that the top plate (16) is hot. As the second notification data, for example, a message “The top plate is hot. The second notification data is also preferably a message for a relatively short time (about 2 to 5 seconds) in order to convey the fact to the user.
The third storage unit (45) is a third unit for transmitting the end of heating to the user when the user misses the voice notification based on the first notification data and the second notification data. Information data is stored. Music and a melody can be illustrated as 3rd alerting | reporting data. It is desirable that the third notification data be music or a melody that is longer than the first and second notification data, for example, about 30 seconds to several minutes. The reason why the third notification data is music or melody is that the user can obtain a more comfortable feeling than repeating messages such as the first and second notification data. Of course, the third notification data may be a message.
The data stored in the first to third storage units (43), (44), and (45) is output to the voice melody notification means (48) in the manner shown in the flowcharts of FIGS. 3 to 7, and is output from the speaker (49). Sound is output.

  Further, the infrared light receiving unit (46) exemplified in the present embodiment as notification data receiving means inputs a message, music, melody, and the like desired by the user from an external device to the cooking device (35). An example of the external device is a portable terminal (90) such as a mobile phone capable of infrared communication as shown in FIG. The first to third notification data can be downloaded via a mobile phone or the like by a melody distribution service on the Internet, or can be downloaded via a network or a personal computer. The downloaded notification data is transmitted from the portable terminal (90) to the infrared light receiver (46) of the heating cooker (10). The control means (40) stores the received first to third notification data in the corresponding storage units (43) (44) (45), and is used when the notification data is output as will be described later. The notification data input by the person is output.

  In addition, in the heating cooker (10) having a mechanism for controlling the operation of the range hood by infrared communication in response to the operation of the heating means (35) (36) (37) (38), Therefore, it is desirable that the notification data cannot be input during the operation of the heating means (35) (36) (37) (38).

Flowchart FIGS. 3 to 7 show an example of control of the heating cooker (10) of the present invention. An example of the heating means is the heating means (35).
With the power switch (21) turned on, the cooking device (10) stands by in a state where the heating standby mode is canceled as shown in FIG. 3 (step 1). At this time, for example, when the user downloads the third notification data from the outside, the process proceeds to a “melody download” subroutine shown in step 2. The subroutine will be described later with reference to FIG.

  When the user operates the operation unit (25) which also serves as a standby mode switching unit (step 3), the user enters a heating standby mode (step 4), and heating conditions are set by operating the operation unit (25) (step 5). ).

When the automatic cooking program (see FIG. 7) is selected by the operation of the operation unit (25) (step 6), the induction heating means (35) is energized (step 7 in FIG. 7).
At this time, by detecting a change in the current flowing through the induction heating means (35) (step 8), the load is appropriate, that is, when the cooking pan is not placed or is not placed at the correct position. (Step 9), the power supply is temporarily stopped (step 10), and a notification to that effect is made (step 11). As an inappropriate load notification, a message such as “Please set the cooking pan correctly” may be output from the voice melody notification means (48) via the speaker (49).
When it is determined that the load is appropriate (step 9), a predetermined automatic cooking program is executed (step 12). When the automatic cooking program is completed (step 13), the induction heating means (35) is energized. Stop (step 14 in FIG. 5).

FIG. 5 is a flowchart of notification data output.
When the energization of the induction heating means (35) is stopped in step 14, the control means (40) uses the first notification data stored in the first storage section (43) as the voice melody notification means (48). ) To the speaker 49 (step 15). As a result, a sound “Heating has been completed” is generated from the speaker (49).

When the output of the first notification data is finished (step 15), the temperature measuring means (39) measures the temperature of the cooking pot via the top plate (16) and outputs it to the control means (35) (step). 16). When the received temperature is equal to or higher than the predetermined temperature, the control means (40) sends the second notification data stored in the second storage section (44) from the voice melody notification means (48) to the speaker (49). (Step 17). This causes the speaker (49) to make a sound saying “The top plate is hot.
If the measured temperature of the temperature measuring means (39) is equal to or lower than the predetermined temperature, the second notification data is not output and the process proceeds to the next step 18.

Next, the third notification data is output.
First, the control means (40) sets notification data corresponding to the heating means from the third storage section (45), for example, a melody (step 18), and uses the set melody as the third notification data to generate a voice melody. The notification means (48) outputs to the speaker (49) (step 19). Thereby, the melody according to a heating means is reproduced | regenerated from a speaker (49). If there is no melody setting, the process proceeds to step 20 without outputting the melody.

  The reproduction of the third notification data is performed until the user operates the operation unit (25), for example, until the operation unit (25) is pushed into the operation panel (24) (step 20), and the user operates the operation unit (25). ) Is operated as described above, if the melody is being reproduced, the melody being reproduced is stopped (step 21).

At this time, the temperature measuring means (39) measures the temperature of the cooking pan via the top plate (16) (step 22) and outputs it to the control means (40). When the received temperature is equal to or higher than the predetermined temperature, the control means (40) sends the second notification data stored in the second storage section (44) from the voice melody notification means (39) to the speaker (49). (Step 23). This causes the speaker (49) to make a sound saying “The top plate is hot.
Thereby, the said flow is complete | finished, it returns to step 1, and a heating standby mode is cancelled | released.

  When a timer cooking program for heating for a predetermined time is selected instead of the automatic cooking program at step 6 (step 30 in FIG. 6), the induction heating means (35) is energized (step 6). Step 31). At this time, as in steps 9 to 11, appropriate load detection is performed (steps 32 to 35). If the load is appropriate, the timer is counted down (step 36), and after the count ends (step 37). In steps 14 to 23, first to third notification data are output.

  Further, when the manual cooking program is selected instead of the timer cooking program in step 30, the induction heating means (35) is energized (step 40 in FIG. 7), which is the same as steps 9-11 above. In addition, appropriate load detection is performed (steps 41 to 44), and if the load is appropriate, heating continues until the user operates the operation unit (25) to stop the heating means (35). (Step 45). When the user stops heating by the operation unit (25) (steps 45 and 46), the control unit (40) uses the first notification data stored in the first storage unit (43) as the voice melody notification unit. (48) to the speaker (49) (step 47). As a result, a sound “Heating has been completed” is generated from the speaker (49).

When the output of the first notification data is finished (step 47), the temperature measuring means (39) measures the temperature of the cooking pot via the top plate (16) and outputs it to the control means (40) (step). 48). When the received temperature is equal to or higher than the predetermined temperature, the control means (40) sends the second notification data stored in the second storage section (44) from the voice melody notification means (48) to the speaker (49). (Step 49). This causes the speaker (49) to make a sound saying “The top plate is hot.
In the case of the manual cooking program, the third notification data is not reproduced because the user is near the heating cooker (10) when the heating is stopped.

According to this flowchart, when the user selects the automatic cooking program and the timer cooking program by operating the operation unit (25), the first notification data and as needed are obtained at the end of heating. Since the second notification data can be output and further the third notification data including melody can be output, even if the user is not near the cooking device (10), the third notification data is used for a while. By playing a certain melody, the end of heating can be reliably transmitted to the user.
Further, since the second notification data can be output again when the user stops the reproduction of the third notification data, it is possible to prevent the top plate (16) from being touched.

  In the above embodiment, the heating means (35) has been described, but the same control can be performed for the other heating means (36), (37) and (38). In the case of the heating means (37) and (38), the step of detecting an appropriate load is unnecessary, and in the case of the heating means (38), the top plate (16) does not become high temperature. The output of the second notification data is also unnecessary.

In step 2, a flow in which the user downloads desired notification data from the outside will be described.
When the user operates the operation button (27) for voice downloading (step 50), the control means (40) checks the operating state of all the heating means (step 51), and there is no heating means during operation. If so, the process proceeds to the download permission mode (step 53).
In this state, when infrared communication is performed from the external device such as the portable terminal device (90) toward the infrared light receiving unit (46), music, melody, voice data are stored in the predetermined storage units (43) (44) (45). And the like are stored (step 54). It should be noted that it is desirable to be able to determine in which storage unit, whether to reproduce the downloaded notification data, the reproduction volume, etc. for each heating means.
When the download is completed, the download permission mode is canceled and the process returns to step 3 in the flowchart of FIG.

  When the user operates the operation unit (25) or the like during the download permission mode, the download is interrupted in order to prevent malfunctions and prevent distraction of cooking. It is desirable to return to step 3 in FIG.

  In addition, in the heating cooker (10) having a mechanism for controlling the operation of the range hood by infrared communication in response to the operation of the heating means (35) (36) (37) (38), Therefore, it is desirable that the notification data cannot be input during the operation of the heating means (35) (36) (37) (38).

  As a method of receiving data from the outside, the cooking device (10) can be connected to a wired or wireless LAN, or the first storage unit (43) and the second storage unit (44) can be inserted from the outside. A good storage medium may be used.

  According to the present invention, even if the user misses the heating end voice message of the heating means (35) (36) (37) (38), the user ends the heating by playing music, a melody, etc. for a predetermined time. Can be transmitted to the user, and the high temperature state of the top plate (16) that cannot be visually confirmed can be transmitted to the user. Moreover, since the user can also reproduce | regenerate the alert data which he desires after completion | finish of a heating, it can cook in a comfortable environment.

  INDUSTRIAL APPLICABILITY The present invention is useful as a heating cooker that can reliably transmit to the user that the heating means has finished heating and that the top plate is hot.
