Description

  The present invention relates to a heating cooker used in a home or business kitchen.

Conventionally, in this type of cooking device, the timer setting of 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, when the set time desired by the user (for example, 3 hours) is exceeded, the timer key is continuously pressed to increase the time, the loop is repeated again until the set time is reached, or the timer cancel key is pressed once, 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. In the timer setting, the set time can be increased or decreased, and when a long-time timer setting is desired, the target set time can be quickly set. Then, it aims at providing the cooking device which improves the usability of a timer.

  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 has an up key for increasing the thermal power, a down key for decreasing the thermal power, and a timer setting mode for setting a timer time. It has a timer key that shifts to, and a timer time display device that displays the timer time or remaining time.When the timer key is pressed when the timer is not set, it shifts to the timer setting mode, and when the up key is pressed, the timer minimum time is decreased. When the key is pressed, the maximum timer time is set.

  This makes it possible to increase / decrease the set time with the up key and down key when setting the timer, and if you want to set the timer for a long time, you can quickly set the target time with the down key. , The usability of the timer can be improved.

  The heating cooker according to 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. .

  A first invention includes a heating device, an operation unit of the heating device, and a control device that receives a signal from the operation unit and controls the heating power of the heating device in a plurality of stages, and the operation unit increases heating power. Key, down key to reduce thermal power, timer key to shift to timer setting mode to set timer time, timer time display device to display timer time or remaining time, timer key when not timer set When the key is pressed, the mode changes to the timer setting mode. When the up key is pressed, the timer minimum time is set, and when the down key is pressed, the timer maximum time is set. With this, when setting the timer, the set time can be increased or decreased with the up key and the down key, and when you want to set the timer for a long time, you can quickly set the target setting time with the down key. The usability of the timer can be improved.

  In the second invention, in particular, in the first invention, when the down key is pressed from the minimum timer time, it is possible to distinguish that the timer time has become 0 by displaying the timer not set. When the up key is accidentally pressed, the timer can be canceled without the timer cancel key.

  In the third aspect of the invention, in particular, in the case of the first aspect, when the up key is pressed from the maximum timer time, it is possible to distinguish that the timer time has become 0 by displaying the timer not set. When the down key is accidentally pressed, the timer can be canceled without the timer cancel key.

  In the fourth aspect of the invention, in particular, in the second or third aspect of the invention, if a state in which neither the up key nor the down key is pressed for a predetermined period of time after the timer non-setting display is displayed during heating, the timer is not set. By turning off the display, canceling the timer setting mode and continuing heating, if the up key or down key is accidentally pressed, or if you want to stop heating by the timer setting, return to normal heating only and not timer By turning off the setting display, it is possible to visually notify the user that the timer heating has been canceled.

  In the fifth invention, in particular, in any one of the second to fourth inventions, when the up key is pressed while the timer non-setting display is displayed, the down key is erroneously pressed by displaying the timer minimum time. In this case, the desired timer time can be easily set without complicated operation.

  In the sixth invention, in particular, in any one of the second to fourth inventions, when the down key is pressed while the timer non-set display is displayed, the up key is erroneously pressed by displaying the timer maximum time. In this case, the desired timer time can be easily set without complicated operation.

  In the seventh invention, in particular, in the first invention, when the down key is pressed from the minimum timer time, the time display is turned off, the timer setting mode is canceled, and the heating is continued during the heating, thereby displaying the timer. Since it disappears, it can be easily understood that the timer setting has been canceled without stopping the heating.

  In the eighth invention, in particular, in the first invention, when the up key is pressed from the timer maximum time, the time display is turned off, the timer setting mode is canceled, and the heating is continued during heating. Since the display disappears, it can be easily understood that the timer setting has been canceled without stopping the heating.

  In the ninth aspect of the invention, in particular, in any one of the first, third, and eighth aspects of the invention, when the up key is held down for a long time, the timer time is increased by a predetermined time, thereby holding the button down for a long time. As a result, the time can be increased at intervals earlier than usual, and the usability can be improved.

  In a tenth aspect of the invention, in particular, in any one of the first, second, and seventh aspects of the invention, the down key is pressed and held down to decrease the timer time by a predetermined time, thereby holding down the key. As a result, the time can be reduced at intervals earlier than usual, and the usability can be improved when it is desired to set a timer for a long time.

  In the eleventh aspect of the invention, in particular, in the fifth or sixth aspect of the invention, when the set time is not displayed due to the long press of the up key or the down key during the timer setting mode, the long press state is temporarily stopped. By not shifting to the timer time display unless it is canceled, it is possible to prevent unintentionally setting a timer for a long time when the timer key is depressed due to a malfunction or malfunction of the timer key.

  In the twelfth invention, in particular, in the eleventh invention, when the set time is not displayed due to a long press of the up key or the down key during the timer setting mode, the long press state for a predetermined time is not released. If the timer is pressed for a long time due to a malfunction or malfunction of the timer key by stopping heating, it is possible to prevent unintentional long-time timer setting and the long press continues for a predetermined time. Since the heating is stopped as an abnormality, safety can be maintained more.

  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 illustrated the induction heating cooking appliance as a heating cooking appliance in embodiment of this invention.

  As shown in FIG. 1, a heating device 2 connected to a commercial power source 1 includes a heating coil 3 for induction heating a pan and the like, and an inverter circuit 4 that causes a high-frequency current to flow 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 as to control the heating power of the heating device 2 in eight stages from “weak” to “strong”. The control device 5 includes a first control unit 5a that increases or decreases the timer time stepwise, a second control unit 5b that stops increasing or decreasing the timer time, and a third control unit 5c that ends the timer mode. Have.

  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, and a timer key 15. 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 normal 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 key 15 performs ON / OFF operation of the timer setting mode. Further, the notification device 14 including a buzzer, a display, etc. operates at the time of reception of each key or warning notification at the time of abnormality. The long press timer 16 measures the time during which the up key 10 or the down key 9 is continuously pressed during the timer setting mode.

  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. Then, 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 device 2 has a function of setting, for example, 45 minutes as a threshold time for preventing forgetting to cut, and stopping heating for preventing 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 key 15 is pressed, the timer setting mode is set, and when the timer is not heated, that is, when no time is displayed on the timer time display device 7, “−−−” is blinked as a timer non-setting display. During the timer heating, the remaining time displayed on the timer time display device 7 is blinked. When the up key 10 is pressed while the display of the timer time display device 7 is blinking, 1 minute is blinked as the timer time.

  Each time the up key 10 is pressed, the timer time increases and a maximum of 9 hours 30 minutes can be set. When the down key 9 is pressed, the timer time blinking on the timer time display device 7 is decreased. When the predetermined timer time blinks and is displayed, when the timer key 15 is pressed again, the timer time changes from blinking to lighting, and the timer time is determined. At the time of heating in a state where the timer time is fixed, both the up key 10 and the down key 9 operate as heating power up and down.

  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 long time. For example, even if the up key 10 is pressed for a long time, the heating power is increased only in one stage. is there. However, the up key 10 and the down key 9 in the timer setting mode increase or decrease the timer time at regular time intervals, that is, at intervals of 0.2 seconds, when long press is detected. In addition, although the increase / decrease of the timer time at the time of long press was made into the fixed space | interval, you may carry out by shortening 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 up key 10 and the down key 9 in the timer setting mode 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 key 15 is pressed in the state 20, “−−−” is blinked and displayed as a timer non-setting display (state 21). Further, when the up key 10 is pressed from that state, 1 minute is blinked and displayed on the timer time display device 7 as the timer minimum time (state 22). When the up key 10 is further pressed, the display of the timer time display device 7 blinks for 2 minutes (state 23). Similarly, every time the up key 10 is pressed, the timer time can be increased by a predetermined increment until 9 hours 30 minutes.

  Similarly, when the down key 9 is pressed from the state 21, the timer time display device 7 blinks and displays 9 hours 30 minutes as the maximum timer time (state 26). When the down key 9 is further pressed, the display of the timer time display device 7 blinks 9 hours (state 25). Similarly, each time the down key 9 is pressed, the time can be reduced by a predetermined increment up to 1 minute. As a result, when it is desired to adjust the timer time for a long time, the time can be reduced from the maximum time with the down key 9 without increasing the time from 1 minute, so that the timer can be adjusted with a smaller number of presses or in a shorter time. .

  For example, when it is desired to set the timer time to 9 hours, the up key 10 must be pressed several tens of times or kept pressed for several seconds. If the down key 9 is used, the timer key 15 and the timer key 15 are set to be pressed three times. be able to. In addition, since both the up key 10 and the down key 9 can be used during the timer time adjustment, for example, it is possible to go back and forth between the state 22 and the state 23 and return when the desired timer time is exceeded. . In particular, when the time is 3 hours or more, the set time increment is 30 minutes. For example, even when the user presses the up key 10 accidentally to set 3 hours and becomes 3 hours 30 minutes, If the down key 9 is pressed once, it 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. The state in FIG. 3 is the same as in FIG. In FIG. 3, when the up key 10 is pressed from the state 26 or the down key 9 is pressed from the state 22, the timer non-setting display “---” is displayed blinking (state 27). Furthermore, if the state in which the up key 10 or the down key 9 is not pressed for a predetermined time (here, 10 seconds) continues in the blinking display state (state 27) of the timer non-setting display “---”, the timer is canceled. Transition to state 20. 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 and decrease keys, and the number of keys can be reduced.

  Further, as shown in FIG. 4, when the up key 10 is pressed from the state 26 or when the down key 9 is pressed from the position of the state 22, 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 up key 10 is pressed from the timer non-setting display “---” (state 21) in FIG. 3, the timer time of 1 minute is displayed (state 22). Similarly, when the down key 9 is pressed from the timer non-setting display “---” (state 21), 9 hours and 30 minutes are displayed (state 26). As a result, when the up key 10 and the down key 9 are adjacent to each other, when the key opposite to the intended key is pressed, the desired time can be easily adjusted, and the usability can be improved.

  In addition, since only the up key 10 and the down key 9 in the timer setting mode are valid for a long time, when the user wants to set the desired set time, the user can keep pressing the key without repeatedly pressing the key. Timer time can be set.

  However, if the up key 10 is continuously pressed, the state 26 to the state 21 are repeated. In this case, if the key is kept pressed due to a failure of the key, the key operation is continued and 45 minutes for preventing forgetting to cut is not activated. Therefore, when the state is changed from the state 26 to the state 21 or from the state 22 to the state 21 by the long press, the state 21 is not changed to the state 22 or from the state 21 to the state 26 unless the long press is once released from the state 21. To. As a result, it is possible to prevent the timer time from continuing to rotate even if the key is pressed for a long time due to a failure or the like. Further, when the timer unset “---” display continues for a predetermined time (for example, 10 seconds) by long-pressing the key, it is determined that the key is abnormal and 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 continues to press the timer increase or decrease key 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 away from the device side.

  In this embodiment, the heating device is induction heating, but it may be a heat source such as a 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.
