[0013]
The operation of the cooking device of the first embodiment configured as described above will be described with reference to FIGS. The heating power of the heating means 1 can be set to, for example, three levels (“strong”, “medium”, “weak”) by operating an input switch 3 (for example, a rotary encoder switch) in the operation unit 11. . For example, when the user switches the input switch 3 to “strong”, the input signal is sent to the heating control means 2, and the heating control means 2 is set to the heating means 1 and the heating power is set to “strong”. Send the corresponding signal. The heating means 1 is energized by the signal, and heats the pan and the like to the heating power ““ strong ””.
[0014]
At this time, the heating control means 2 simultaneously sends a signal of the heating power “strong” to the notification control means 7. Then, as shown in FIG. 2C, the notification control means 7 sends a notification control signal corresponding to the heating power “strong”, for example, a pulse of 0.1 seconds to the notification unit 6, and the notification unit 6 temporarily Then, a buzzer sound is generated by a pulse of 0.1 seconds.
Further, when the user operates the input switch 3 to change the heating power setting to “medium”, a heating power “medium” signal is sent from the heating control means 2 to the heating means 1 and the notification control means 7, and FIG. ), A signal corresponding to the heating power “medium”, for example, a pulse of 0.5 seconds, is sent to the notification unit 6, and the buzzer of the notification unit 6 generates a buzzer sound of 0.5 seconds.
In this way, when the setting is changed from “Strong” → “Medium” → “Weak” → “Strong”, “Medium” is changed to 0.5 seconds, which is different from the notification sound of other firepower settings. ing.
[0015]
As described above, by changing the notification sound in response to a specific thermal power setting, the user can easily set the thermal power by hearing without depending on the sight by a simple configuration with a single input switch. Even if the thermal power setting is cyclically changed like “Medium” → “Weak” → “Strong” → “Medium” → “Weak” → “Strong” It can be easily determined based on the thermal power settings with different notification sounds.
[0016]
The input switch 3 may be a rotary encoder switch or a switch that can set the heating power to “strong”, “medium”, “weak”, “strong”, or the like.
[0017]
Embodiment 2. FIG.
In the first embodiment, there is no particular association between the operation start operation of the input switch and the specific thermal power setting that changes the notification sound. However, in the present embodiment, when the input switch starts to be operated, the notification is performed. It is designed to have a specific firepower setting that changes the sound. The difference from FIG. 1 of the first embodiment in the configuration is that the notification control means 7 has a memory for storing a specific setting (hereinafter referred to as default setting), and is determined in advance when the user operates the input switch 3 for the first time. It is the point that it is made to operate with the fired power. The default setting is the thermal power setting that the user would normally use most. For example, as shown in FIG. 2 of the second embodiment, the thermal power “medium” is set to the length of the notification sound, and the other thermal power is set to 0. 0.5 seconds, which is different from 1 second.
Further, the input switch 3 is a rotary encoder switch, for example, and can be set in three stages (“strong”, “medium”, “weak”).
[0018]
Next, the operation of the present embodiment will be described with reference to FIG. FIG. 3 (a) shows the state of the thermal power and notification sound when the rotary power encoder switch (RE) is operated clockwise to set the heat power “strong”, and FIG. 3 (b) shows the rotary power encoder switch. The state of the thermal power and the notification sound when (RE) is operated counterclockwise to set the thermal power “weak” is shown.
[0019]
When the power (not shown) is turned on and the heating power is set to “strong”, the rotary encoder switch (RE), which is the input switch 3, is operated clockwise as shown in FIG. Then, based on the input signal of the rotary encoder switch (RE), the heating control means 2 outputs the heat power signal “medium” to the notification control means 7 because the heat power “medium” is set as the default setting. Based on the signal, the notification control means 7 outputs a notification signal for 0.5 seconds to the notification unit 6, and the notification unit 6 sounds a notification sound for 0.5 seconds. This is the first notification sound.
[0020]
When it is further turned to the right, the heating control means 2 outputs a heating power signal “strong” to the notification control means 7 based on the input signal of the rotary encoder switch (RE), and the notification control is performed based on this signal. The means 7 outputs a 0.1 second notification signal to the notification unit 6, and the notification unit 6 sounds a 0.1 second notification sound. This is the second notification sound, and it can be seen that the firepower is set to “strong”. At this time, the heating control means 2 sends a signal corresponding to the heating power “strong” to the heating means 1. The heating means 1 is energized by the signal to heat the pan and the like.
Note that the thermal power unit 1 is operated by operating the rotary encoder switch (RE), for example, so that it is 2 seconds after the alarm sound starts to sound with the medium power set as the default setting. . This is to prevent the thermal power means 1 from operating at the thermal power “medium” before setting the thermal power “strong”.
[0021]
When setting the heating power to “weak”, the rotary encoder switch (RE) is operated counterclockwise as shown in FIG. Then, based on the input signal of the rotary encoder switch (RE), the heating control means 2 outputs the heat power signal “medium” to the notification control means 7 because the heat power “medium” is set as the default setting. Based on the signal, the notification control means 7 outputs a notification signal for 0.5 seconds to the notification unit 6, and the notification unit 6 sounds a notification sound for 0.5 seconds. This is the first notification sound.
[0022]
Then, when further turned to the left, the heating control means 2 outputs the thermal power signal “weak” to the notification control means 7 based on the input signal of the rotary encoder switch (RE), and the notification control is performed based on this signal. The means 7 outputs a 0.1 second notification signal to the notification unit 6, and the notification unit 6 sounds a 0.1 second notification sound. This is the second notification sound, and it can be seen that the firepower is set to “weak”. At this time, the heating control means 2 sends a signal corresponding to the heating power “weak” to the heating means 1. The heating means 1 is energized by the signal to heat the pan and the like.
[0023]
As described above, the thermal power setting that the user would normally use is the default setting, and the alarm sound is different from other thermal power settings for this thermal power setting, so a simple configuration with a single input switch In the heating cooker that can easily determine the setting of the thermal power by hearing without depending on the visual sense in operation, and moreover, in the heating cooker that enables multi-stage thermal power setting, Setting of thermal power that is frequently used can be executed with the simplest operation.
[0024]
Embodiment 3 FIG.

FIG. 4 is an explanatory diagram of the setting of the heating power and the notification sound of the heating cooker according to the fourth embodiment of the present invention, and FIG. 5 is an explanatory diagram of the heating power setting and the notification sound by operating the input switch. The configuration is different from the second embodiment in the default setting. In the heating control means 2, the thermal power setting is set in five stages as shown in FIG. 4: thermal power “strong”, thermal power 4, thermal power 3, thermal power 2, and thermal power “weak”.
Of these multi-stage thermal power settings, the median value, for example, the thermal power setting “3” is set as a default setting, and the length of the notification sound is different from 0.1 seconds when other thermal powers are set. Seconds.
In addition, the input switch 3 is, for example, a rotary encoder switch, and can be set to a heating power “strong”, a heating power 4, a heating power 3, a heating power 2, and a heating power “weak”.
[0025]
Next, the operation of this embodiment will be described with reference to FIG. FIG. 5 (a) shows the state of the thermal power and notification sound when the rotary power encoder switch (RE) is operated clockwise to set the heat power “strong”, and FIG. 5 (b) shows the rotary power encoder switch. The state of the thermal power and the notification sound when (RE) is operated counterclockwise to set the thermal power “weak” is shown.
[0026]
When the power (not shown) is turned on and the heating power is set to “strong”, the rotary encoder switch (RE) is operated clockwise as shown in FIG. Then, based on the input signal of the rotary encoder switch (RE), the heating control means 2 outputs the thermal power signal “3” to the notification control means 7 first because the thermal power “3” is set as the default setting. Based on the signal, the notification control means 7 outputs, for example, a notification signal of 0.5 seconds to the notification unit 6, and the notification unit 6 sounds a notification sound of 0.5 seconds by this signal. This is the first notification sound.
[0027]
Then, when further turned to the right, the heating control means 2 outputs the thermal power signal “4” to the notification control means 7 based on the input signal of the rotary encoder switch (RE), and the notification control is performed based on this signal. The means 7 outputs a 0.1 second notification signal to the notification unit 6, and the notification unit 6 sounds a 0.1 second notification sound. This is the second notification sound. When the notification sound is turned further to the right, the notification unit 6 sounds a notification sound of 0.1 seconds by the same operation. This is the third notification sound, and it can be seen that the heating power is set to “strong”. At this time, the heating control means 2 sends a signal corresponding to the heating power “strong” to the heating means 1. The heating means 1 is energized by the signal to heat the pan and the like.
[0028]
When setting the heating power to “weak”, the rotary encoder switch (RE) is operated counterclockwise as shown in FIG. Then, based on the input signal of the rotary encoder switch (RE), the heating control means 2 outputs the thermal power signal “3” to the notification control means 7 first because the thermal power “3” is set as the default setting. Based on the signal, the notification control means 7 outputs, for example, a notification signal of 0.5 seconds to the notification unit 6, and the notification unit 6 sounds a notification sound of 0.5 seconds by this signal. This is the first notification sound.
[0029]
When it is further turned to the left, the heating control means 2 outputs the thermal power signal “2” to the notification control means 7 based on the input signal of the rotary encoder switch (RE), and the notification control is performed based on this signal. The means 7 outputs a 0.1 second notification signal to the notification unit 6, and the notification unit 6 sounds a 0.1 second notification sound. This is the second notification sound. When the notification sound is turned further to the right, the notification unit 6 sounds a notification sound of 0.1 seconds by the same operation. This is the third notification sound, and it can be seen that the firepower is set to “weak”. At this time, the heating control means 2 sends a signal corresponding to the heating power “weak” to the heating means 1. The heating means 1 is energized by the signal to heat the pan and the like.
[0030]
Thus, when the rotary encoder switch (RE) is turned to the right, the setting changes in the order of thermal power 3 → thermal power 4 → thermal power “strong”, and when turned to the left, thermal power 3 → thermal power 2 → thermal power “weak” The setting changes in the order of, and a notification sound of 0.5 second → 0.1 second → 0.1 second is sounded corresponding to each heating power setting. That is, with the same number of steps as the left and right, the fire power “weak” and the fire power “strong” are set around the default median fire power “3”.
[0031]
As described above, since the notification sound is different from the other heating powers with respect to the median thermal power setting, it is easy to determine the median thermal power, so-called medium fire, with a simple configuration with a single input switch. At the same time, both the firepower “strong” and the firepower “weak” can be varied with the same number of steps, making it easier to make auditory judgments and improving ease of use for multi-stage firepower settings. Can be achieved.
