Description

  The present invention relates to a cooking device used in a home or business kitchen.

Conventionally, in this type of cooking device, the timer setting for the heating time is that the timer time is displayed on the timer time display device by pressing the timer key, and the timer time is increased each time the timer key is pressed. The predetermined timer time can be set (see, for example, Patent Document 1).
Japanese Patent No. 3264235

  However, in the above-described conventional configuration, the setting of the timer time only increases the time by pressing the timer key, and cannot be decreased. Therefore, if it exceeds the set time that the user wants (for example, 3 hours), keep pressing the timer key to increase the time and repeat the loop again until the set time is reached, or press the timer cancel key once. Then I had to press the timer key again to set it again. Further, when it is desired to set a timer for a long time (for example, 9 hours), the timer key must be kept pressed, which is inconvenient.

  The present invention solves the above-mentioned conventional problem, and when setting a timer, it is possible to increase / decrease the set time, and when it is desired to set a timer for a long time, a timer that can be quickly set to a target set time. An object is to provide a cooking device that improves usability.

In order to solve the above-described conventional problems, the cooking device of the present invention is configured such that the operation unit of the heating device increases the set time when setting the timer time, and the timer increase key that decreases the set time. a key, and a timer time display device that displays the timer time or the remaining time, press the timer minimum time timer increases key when not in timer setting timer time has not been set, if you press the timer decrease key The maximum timer time is set.

  As a result, when setting a timer, the set time can be increased or decreased using the timer increase key and timer decrease key, and if you want to set a timer for a long time, operate the timer decrease key to quickly set the target time. Can be set to

  The heating cooker of the present invention can increase / decrease the set time, and if it is desired to set a timer for a long time, it can be quickly set to the target set time, and the usability of the timer can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment)
The figure has shown the heating cooker in embodiment of this invention.

  In FIG. 1, a heating device 2 connected to a commercial power source 1 has a heating coil 3 for induction heating a pan or the like, and an inverter circuit 4 for flowing a high-frequency current through the heating coil 3. The control device 5 receives the signal from the operation unit 6 of the heating device 2 and controls the inverter circuit 4 so that eight stages of thermal power from “weak” to “strong” are applied to the pan or the like. Further, the control device 5 includes a first control unit 5a, a second control unit 5b, and a third control unit 5c. The first control unit 5a gradually increases or decreases the timer time, the second control unit 5b stops increasing or decreasing the timer time, and the third control unit 5c ends the timer mode.

  The operation unit 6 includes a timer time display device 7, a thermal power display device 8, a down key 9, an up key 10, a heating off / on key 11, a timer increase key 15, and a timer decrease key 16. The timer time display device 7 displays the timer time or the remaining time, and includes an LED and an LCD. The thermal power display device 8 is composed of LEDs. The timer time is the time set by the user, and the remaining time is the remaining time until the timer time becomes zero. The down key 9 and the up key 10 are used to operate the thermal power down and up, and are displayed on the thermal power display device 8. The heating off / on key 11 performs heating ON / OFF operation.

  The timer increase key 15 is a key for increasing the set time when setting the timer time, and the timer decrease key 16 is a key for decreasing the set time. When the timer increase key 15 is pressed when the timer is not set, the timer minimum time is set. When the timer decrease key 16 is pressed, the timer maximum time is set.

  In addition, the notification device 14 including a buzzer sounds when receiving each key or notifying a warning when there is an abnormality. The long press timing device 17 measures the time during which the timer increase key 15 or the timer decrease key 16 is continuously pressed.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, to perform heating, the user presses the heating off / on key 11. Then, a signal is sent from the operation unit 6 to the control device 5 so that the set thermal power becomes “5”, the control device 5 controls the inverter circuit 4, and the thermal power display device 8 has “low” to “5”. LED lights up. Here, “weak”, 1, 2, 3, 4, 5, 6, and “strong” of the thermal power are about 120 W, about 235 W, about 370 W, about 500 W, about 700 W, about 1000 W, about 1450 W, and about 2000 W, respectively. Is set. The setting can be changed to an arbitrary heating power by using the down key 9 or the up key 10, and the heating power is displayed on the heating power display device 8 in accordance with the setting change. When the heating is finished, the heating off / on key 11 is pressed again.

  The heating cooker 2 has a function of setting, for example, 45 minutes as a threshold time for preventing forgetting to cut, and stopping heating to prevent forgetting to turn off when no operation has been performed for 45 minutes. Furthermore, the user can set a timer when he / she wants to turn off the heating automatically after a set time by the timer heating. When the timer increase key 15 is pressed, the timer time is displayed on the timer time display device 7, and whenever the timer increase key 15 is pressed, the timer time increases and can be set up to a maximum of 9 hours 30 minutes. When the timer decrease key 16 is pressed, the timer time displayed on the timer time display device 7 is decreased.

  Normally, each key recognizes that the key has been pressed in 0.1 seconds, but it is determined that the key is pressed for a longer time, and no operation is continued except for the timer increase key 15 and the timer decrease key 16. For example, even if the up key 10 is pressed for a long time, the heating power increases only in one stage. When the timer increase key 15 and the timer decrease key 16 detect a long press, the timer time is increased or decreased at regular time intervals, that is, at intervals of 0.2 seconds. In addition, although the increase / decrease interval of the timer time at the time of long press was made constant, you may shorten in steps.

  If the timer time is long, the difference in the timer setting time of 5 minutes or 10 minutes is not very meaningful. Therefore, the time increment of the timer is 1 minute from 1 minute to 20 minutes, 5 minutes from 20 minutes to 1 hour, 10 minutes from 1 hour to 3 hours, and 30 from 3 hours to 9 hours 30 minutes. It is set in increments of minutes. In addition, the timer can be set regardless of the presence or absence of heating.

  Next, the state displayed on the timer time display device 7 when the timer increase key 15 and the timer decrease key 16 are pressed will be described with reference to FIGS.

  First, in FIG. 2, a state 20 is a state when a timer is not set and a timer is not set. At this time, the operation of the heating device 2 may be either. When the timer increase key 15 is pressed in the state 20, the timer mode is set and the timer time display device 7 displays 1 minute as the timer time (state 21). When the timer increase key 15 is further pressed, the display of the timer time display device 7 displays 2 minutes (state 22). Similarly, every time the timer increase key 15 is pressed, the timer time can be increased in a predetermined increment until 9 hours 30 minutes (states 22 and 23).

  Similarly, when the timer decrease key 16 is pressed from the state 20, the timer mode is set, and the timer time display device 7 displays 9 hours and 30 minutes as the timer time (state 25). When the timer decrease key 16 is further pressed, the display of the timer time display device 7 displays 9 hours (state 24). Similarly, every time the timer decrease key 16 is pressed, the time can be decreased in a predetermined increment up to 1 minute. This makes it possible to reduce the time from the maximum time using the timer decrease key 16 without increasing the time from 1 minute, so that the timer can be adjusted by pressing a smaller number of times or in a shorter time. it can.

  For example, when it is desired to set the timer time to 9 hours, the timer increase key 15 must be pressed several tens of times or kept pressed for several seconds, but if the timer decrease key 16 is used, it can be adjusted by pressing twice. Since both the timer increase key 15 and the timer decrease key 16 can be used during the timer time adjustment, for example, it is possible to go back and forth between the state 21 and the state 22 and return when the desired timer time is exceeded. Can do. In particular, if it is 3 hours or more, the set time increment is 30 minutes. For example, even if the timer increase key 15 is accidentally pressed to set 3 hours and it becomes 3 hours 30 minutes, If the timer decrease key 16 is pressed once, the time can be set to 3 hours. Therefore, it is not necessary to cancel the timer and adjust the timer time again.

  Next, FIG. 3 will be described. States 20 to 25 in FIG. 3 are the same as those in FIG. In FIG. 3, when the timer increase key 15 is pressed from the state 25 or the timer decrease key 16 is pressed from the state 21, a timer release display (“——”) is displayed. Furthermore, if the state in which the timer increase key 15 or the timer decrease key 16 is not pressed is continued for a predetermined time (here, 10 seconds) in the display state of the timer release display (state 26), the state is shifted to the state 20 because the timer is canceled. At this time, if the heating device 2 is heating, only the timer setting is canceled. Thus, even if there is no key for canceling the timer, the timer can be canceled only by the timer increase key 15 and the timer decrease key 16, and the number of keys can be reduced.

  Further, as shown in FIG. 4, when the timer increase key 15 is pressed from the state 25 or when the timer decrease key 16 is pressed from the state 21 position, the state 20 may be shifted to. In this case, when the state is returned to the state 20, the timer display time disappears, so that the cancellation can be easily notified.

  Further, when the timer increase key 15 is pressed from the timer release display of FIG. 3 (state 26), the timer time of 1 minute is displayed (state 21). Similarly, when the timer release display is displayed (state 26) and the timer decrease key 16 is pressed, 9 hours and 30 minutes are displayed (state 25). Thereby, when the timer increase key 15 and the timer decrease key 16 are adjacent to each other, when the key opposite to the intended key is pressed, it can be easily adjusted to a desired time, and usability can be improved. .

  Further, since the long press only for the timer increase / decrease key is valid, the timer time can be set by continuing to press the key without performing the operation of pressing the key many times when it is desired to match the desired set time.

  However, if the timer increase key 15 is kept pressed, the states 26 to 21 are repeated. In this case, if the key continues to be pressed due to a failure of the key, the key operation continues and 45 minutes of forgetting to turn off will not work. Therefore, when the state is changed from the state 25 to 26 or from the state 21 to 26 by the long press, the state 26 is not changed to the state 21 or the state 26 to 25 unless the long press is once released from the state 26. As a result, it is possible to prevent the timer time from continuing even if the key is pressed for a long time due to a failure or the like. Further, when the timer release display for releasing the long press of the key continues for a predetermined time (for example, 10 seconds), it is determined that the key is abnormal and the heating is stopped. Thereby, it is possible to make the cooking device safer.

  In addition, when the increase in the timer time stops due to an abnormal long press, the notification device 14 notifies the abnormality. As a result, when the user keeps pressing the timer increase key 15 or the timer decrease key 16 to adjust the timer time, it is possible to know why the time increase has stopped. Alternatively, it is possible to notify that an abnormality has occurred in the device even when it is away from the device side.

  In the present embodiment, the heating device 2 is induction heating, but may be a heat source such as gas or a sheathed heater. Each key generally has a switch configuration, but the same effect can be obtained as a capacitance-sensitive touch key.

  As described above, the heating cooker according to the present invention can increase and decrease the set time, and can quickly set the target set time when you want to set the timer for a long time, improving the usability of the timer. Therefore, it can also be applied to devices having a timer function such as a microwave oven, a jar rice cooker, a jar pot, an induction heating cooker, a gas table, a gas cooker, a home bakery, and a toaster.
