JP 2008-71550 A ([0011], FIG. 3)

  For example, as a cooking device as described in Patent Document 1, there is known a cooking device configured to emit a notification sound (operation sound or voice navigation message) when a user operation is accepted. The volume of the notification sound of such a cooking device can be selected by the user from a fixed volume or a plurality of preset fixed volumes.

  However, in the conventional cooking device, the volume of the notification sound output from the cooking device is not associated with the presence or absence of the user. For example, the cooking device described in Patent Document 1 can change the number of operations of the user based on the presence or absence of the user detected by the human body sensor, but the volume of the notification sound is not considered. For this reason, a notification sound having a constant volume is output regardless of the distance between the user and the cooking device. Therefore, when the notification sound is set to be small in advance, and there is a user at a place away from the cooking device, there is a problem that the user may miss the notification sound. It was.

  The present invention has been made against the background of the above-described problems, and an object of the present invention is to provide a heating cooker that can reduce a user's oversight of informed voice.

  A heating cooker according to the present invention detects a presence of a user, a heating means for heating an object to be heated, a notification means for outputting sound, a control means for controlling the heating means and the notification means, and The control means determines whether or not there is a user based on the detection result of the human sensor before outputting the sound by the notification means. If it is determined that there is a sound, a sound having a first volume is output from the notification means, and if it is determined that there is no user, a sound having a volume higher than the first sound volume is output from the notification means. Is.

  According to the present invention, when the user is present at a position away from the cooking device, the user is notified with a louder sound than when the user is present near the cooking device. For this reason, even if it is a case where a user exists in the position away from the cooking-by-heating machine, it can reduce that a user misses the audio | voice alert | reported.

  The speaker 61 corresponds to “notification means” in the present invention.

FIG. 4 is a flowchart showing the control contents of the control means 13 of the cooking device 100 according to the first embodiment.
Hereinafter, the control content of the control means 13 is demonstrated in order using FIG.

(Step S10)
The control means 13 determines whether or not an operation signal is output from the upper surface operation unit 8 or the front operation unit 11 while the heating cooker 100 is turned on, so that an operation input related to heating is performed by the user. Judge whether or not.
When it is determined that the operation related to heating has been performed (Yes in step S10), the control unit 13 proceeds to step S20.
When it is determined that the operation related to heating is not performed (No in step S10), the control unit 13 repeats the determination in step S10.

Here, “operation related to heating” refers to, for example, operations shown in the following (A-1) to (A-3).
(A-1) An operation for setting the heating power performed to heat the object to be heated 41 placed on the top plate 2 or the cooked food 21 in the grill portion 12 with a predetermined heating power.
(A-2) Operation for setting a target temperature to be preheated so as to raise the temperature in the object to be heated 41 or the grill portion 12 placed on the top plate 2 to a predetermined temperature.
(A-3) An operation for setting the heating time of the heated object 41 placed on the top plate 2 or the cooked food 21 in the grill portion 12.

(Step S20)
The control means 13 controls the heater drive circuit 14 and the inverter circuit 15 based on the operation signal output from the upper surface operation unit 8 or the front operation unit 11 according to the operation performed by the user in step S10. Is output and heating control is performed.

(Step S30)
The control means 13 determines whether or not to output sound from the speaker 61 based on a signal related to timing of the timer 13a, signals output from the temperature sensors 51a and 51b, and the like.
Here, the case of “outputting sound” is, for example, the case shown in the following (B-1) to (B-3). The following (B-1) to (B-3) are scenes that can occur mainly after the operations (A-1) to (A-3) described above are performed.
(B-1) The detected temperature of the temperature sensors 51a and 51b exceeds a predetermined temperature.
(B-2) The temperature detected by the temperature sensors 51a and 51b reaches a predetermined target temperature.
(B-3) When the time measured by the timer 13a reaches the set heating time.

If it is determined that the sound is to be output (Yes in step S30), the control unit 13 proceeds to step S40.
When it is determined that the sound is not output (No in step S30), the control unit 13 returns to step S20 and continues the heating control.

(Step S40)
The control means 13 determines whether or not there is a user in front of or near the cooking device 100 depending on whether or not a signal indicating the presence of the user is output from the human sensor 31 for a predetermined time.
When the signal indicating the presence of the user is output from the human sensor 31 for a predetermined time, the control means 13 determines that the user is present in front of or near the cooking device 100 (Yes in step S40). The process proceeds to step S60.
When the signal indicating the presence of the user is not output from the human sensor 31 or when the signal indicating the presence of the user is output for less than a predetermined time, the control means 13 is in front of or near the heating cooker 100. (No in step S40), the process proceeds to step S50.

  In step S40, an arbitrary time can be adopted as the “predetermined time” used as a reference for determining whether or not the user is present by the control means 13.

(Step S50)
The control means 13 outputs the sound from the speaker 61 at a volume that is higher than the first fixed volume that is a preset fixed volume or a volume set by the user, and returns to step S20. As described above, when there is no user in front of or near the cooking device 100 (No in step S40), the control means 13 sets the volume of the sound output from the speaker 61 to a volume higher than the first volume. Thus, even when the user is present at a location away from the heating cooker 100, the sound is surely transmitted to the user. Note that the user may be able to set the volume output in step S50.

(Step S60)
The control means 13 outputs sound from the speaker 61 at a preset fixed volume or a first volume which is a volume set by the user, and returns to step S20. Thus, when there is a user in front of or near the cooking device 100 (Yes in step S40), the control means 13 sets the volume of the sound output from the speaker 61 to the initial volume. The first volume is set. For this reason, the sound output from the speaker 61 is unlikely to be excessively loud for a user who is cooking in front of or near the cooking device 100.

  Note that the sound output from the speaker 61 in step S50 or step S60 is, for example, a sound notifying that a predetermined temperature has been exceeded (in the case of (B-1)) or a sound notifying that preheating has ended (( In the case of B-2), it is a sound (in the case of (B-3)) notifying that the set heating time has elapsed.

  In FIG. 4, it has been described that voice output is performed once in step S50. However, in the case where the user does not exist in front of or near the heating cooker 100, for example, in the object to be heated 41 or the grill 12 For example, the control means 13 may repeatedly output the sound to the speaker 61 a plurality of times when notifying that the temperature of the battery is high or notifying the user of the next operation input. In the case of performing audio output a plurality of times, if the user is not present in front of or near the cooking device 100, the control means 13 sets the volume output from the speaker 61 for the second and subsequent audio outputs. , Make it bigger than last time. By doing so, the volume of the sound output from the speaker 61 is gradually increased within a range not exceeding the maximum volume. For this reason, even when a user exists in the place away from the heating cooker 100, possibility that the audio | voice output from the speaker 61 will be transmitted to a user can be improved.

  In the case of performing sound output a plurality of times, the sound volume may be increased when sound output is performed a predetermined number of times instead of increasing the sound volume every time. By doing in this way, since the audio | voice output from the speaker 61 does not become loud rapidly, the disgust of the user by a large sound volume can be suppressed. Also, the user may be able to set the volume level to be raised.

  In addition, when it is detected that the user is present in front of or near the heating cooker 100 after performing sound output a plurality of times, the control unit 13 performs sound output from the speaker 61 thereafter. May be returned to the first volume which is the initial volume. By doing in this way, an excessively large sound volume is not output for the user existing in front of or near the cooking device 100, and the user does not feel disgust due to the large sound volume.

(Effect of Embodiment 1)
As described above, the heating cooker 100 according to the first embodiment is configured so that the user can use the front of the heating cooker 100 based on the signal output from the human sensor 31 before the sound is output by the speaker 61. Or it is determined whether it exists in the vicinity. And when a user determines with not existing in front of the heating cooker 100 or its vicinity, the audio | voice of a louder volume than the case where it exists is output from the speaker 61. FIG.
For this reason, when a user exists in the position away from the cooking-by-heating machine 100, the alert | report to a user is performed with the audio | voice of a louder volume than the case where a user exists near the cooking-by-heating machine 100. Therefore, even if a user exists in the position away from the heating cooker 100, it can reduce that a user misses the alert | reported audio | voice.

  In addition, the heating cooker 100 according to the first embodiment is a case where it is determined that there is no user in front of the heating cooker 100 or in the vicinity thereof. The volume of the output voice was gradually increased. For this reason, even when a user exists in a place away from the heating cooker 100, the possibility that the voice from the heating cooker 100 reaches the user can be increased, and the notified voice is used. Can be reduced.

  In the first embodiment, it has been described that the volume of sound output from the speaker 61 varies depending on whether or not there is a user in front of or near the cooking device 100. However, whether to perform audio output may be switched depending on whether there is a user. For example, in the case of outputting a sound prompting the user to return to the front of the cooking device 100, if the presence of the user can be detected based on the output from the human sensor 31, the sound is output. Do not output, and output audio only when the presence of the user cannot be detected. In this way, energy saving effect can be obtained by suppressing useless sound output, and the user does not feel bothered by useless sound.

  Moreover, in this Embodiment 1, when there was no user in front of the heating cooker 100 or its vicinity, it demonstrated that audio | voice output was carried out by the volume larger than a 1st volume, but such an automatic The function of increasing the volume may be stopped by the user's selection. Specifically, an operation button or the like that allows the user to set whether or not to automatically adjust the volume is provided, and when the setting is made so that the volume adjustment is not automatically performed by the operation button, Regardless of whether or not the user is detected by the human sensor 31, the sound is output at the first volume. By doing in this way, the cooking device 100 suitable for a user's use environment can be obtained.

  Moreover, although the example of the induction heating cooking appliance was demonstrated in this Embodiment 1, it is not limited to this, It can apply also to the cooking appliance etc. which heat with a gas cooking appliance or an electric heater.
