Capacitance type touch keys are provided on the top plate on the top of the device to improve cooking operability. For example, a pan is placed on the touch keys or water in the pan is spilled. When the key is continuously pressed for a predetermined time or longer, there is an apparatus that detects an abnormality and stops heating, and prohibits acceptance of a touch key to improve the safety of the device (for example, see Patent Document 1).
JP 2003-279055 A

  However, in the conventional configuration, for example, when a timer function for stopping heating at a set time is provided, that is, when a timer key for setting time is provided in the touch key, it is one of the touch keys. If the timer key is pressed continuously for more than a certain time, it detects an abnormality and stops heating, and prohibits the acceptance of touch keys. There was a problem that the repeat function could not be realized.

  This invention solves the said conventional subject, and it aims at providing the cooking device which aimed at coexistence of the operativity improvement by a key repeat function, and the safety | security improvement of the apparatus by key long press abnormality detection. Is.

  In order to solve the above-described conventional problems, the cooking device of the present invention is configured such that the key long press abnormality detecting means detects abnormality among keys of a plurality of touch keys that are continuously received in a predetermined cycle. The chance of not detecting or detecting an abnormality than other keys is substantially reduced.

  As a result, it is possible to achieve both improvement in operability by the key repeat function and improvement in the safety of the device by detecting abnormal key presses.

  The cooking device of the present invention can achieve both improvement in operability by the key repeat function and improvement in equipment safety by detecting abnormal key presses.

  The first invention is a heating means for heating a pan, a top plate provided above the heating means, a plurality of touch keys provided on the top plate, and a key for detecting a pressed state of the plurality of touch keys. A long press abnormality detecting means and a control means for controlling the output of the heating means based on input signals from the plurality of touch keys and suppressing the output of the heating means based on the input signals from the key long press abnormality detecting means. And the key long press abnormality detecting means does not detect abnormality or detects an abnormality more than other keys in the plurality of touch keys that continuously accept key presses in a predetermined cycle. By using a heating cooker that substantially reduces the chance to perform, both improved operability with the key repeat function and improved equipment safety by detecting abnormal key presses It is those that can mow it.

  For keys that do not have a key repeat function, the key press abnormality detecting means detects an abnormality when the key press continues for a predetermined time or more, and the control means detects the heating means based on an input signal from the key long press abnormality detecting means. Limit output. For example, if the pan is placed on a key for setting the output of the heating means to be turned on or off, or if the water in the pan is blown out, the control means will receive the key by mistake, and the heating means will not be intended by the user. Even when the output is started, after a predetermined time, the control means detects an abnormality based on the input signal from the key long press abnormality detection means and stops or reduces the output of the heating means, so that the user is not nearby The safety of the equipment can be improved.

  According to a second aspect of the invention, in particular, in the first aspect of the invention, the key long press abnormality detecting means determines the time until an abnormality is detected in a key continuously received at a predetermined period from the time until an abnormality is detected in another key. By setting the length too long, normal key operation does not detect anomalies, and the key press state continues when the pan is placed on the key with the key repeat function or the food in the pan is blown out. In such an abnormal state, the key press abnormality detection means detects abnormality, and the control means can stop or reduce the output of the heating means to improve safety when the user is not nearby.

  According to a third aspect of the invention, in particular, in the second aspect of the invention, the key long press abnormality detecting means determines the time until abnormality is detected in the key continuously received at a predetermined cycle based on the key that the control means continuously receives. By associating the setting to be changed with the number of rounds, for example, in the key having the setting number of 10 and changing the setting every 0.2 seconds during the key repeat function, the setting is changed to 3 by the key repeat function. After one round (that is, 10 × 0.2 seconds × 3 = 6.0 seconds), the key long press abnormality detection means can detect abnormality. As a result, it is possible to set a set number of rounds that cannot be performed by a normal key repeat operation, and flexibly even if the number of settings changed by the key having the key repeat function and the key repeat cycle are changed. Can respond.

  According to a fourth aspect of the invention, in particular, in the first aspect of the invention, the key long press abnormality detecting means detects abnormality while the control means continues to accept the key press in the key that is continuously accepted at a predetermined cycle. First, even if the key press is no longer accepted, an abnormality is detected if the key press continues for a predetermined time or longer. In the case of a key repeat function that changes settings and does not accept key presses when the maximum or minimum setting is reached, it prevents accidental detection of errors during the key repeat period, and the setting change by the key repeat function is completed. When the key continues to be pressed afterwards, it is possible to detect an abnormality and improve the safety of the device.

  In the fifth invention, in particular, in any one of the first to fourth inventions, the key for setting the output level of the heating means is a key that is continuously received at a predetermined period, whereby the output level of the heating means is set. If the key to be set is continuously pressed, the output level can be changed in a predetermined cycle, and the operability when changing the heating power can be improved.

  In a sixth aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, the key for setting the timer time is a key that is continuously received at a predetermined cycle, so that when the key is continuously pressed, the key is set at a predetermined cycle. The timer time can be changed, and the operability when changing the timer time can be improved.

  In the seventh aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, the key for selecting the automatic cooking menu is a key for continuously receiving the automatic cooking menu at a predetermined cycle. If the pressing is continued, the menu setting can be changed at a predetermined cycle, and the operability at the time of menu selection can be improved.

  In an eighth aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, the key for changing the control temperature of the cooked food is a key that is continuously received at a predetermined period. If the key to be set is continuously pressed, the control temperature can be changed in a predetermined cycle, and the operability when changing the control temperature can be improved.

  According to a ninth aspect of the invention, in particular, in the second aspect of the invention, a plurality of keys continuously received at a predetermined cycle are provided, and the key long press abnormality detecting means determines a time until abnormality is detected in the plurality of continuously received keys. By setting different values for each, even if the number of settings to be changed by each key and the key repeat cycle are different, the key long press abnormality detection means can detect an abnormality in the shortest time and improve the safety of the device. it can.

Select the performance from "Low", "Medium", or "Strong" and switch to auto cooking mode when pressing the roaster off / on key 10c is detected, and switch to initial mode when detecting pressing the roaster cancel key 10h. To do.

  The all-mode control means 16 is used when the mode control means 16a to 16c receives the touch keys 13 to change the state or when an abnormality is detected based on the input signals from the key long press abnormality detection means 15a to 15c. Then, the notification means 17 is driven to notify that fact audibly.

  Next, the timer function in each mode control means 16a-16c is demonstrated.

  The mode control means 16a has a timer function for turning off the output of the right induction heating means 1 when the set time from 1 minute to 9 hours 55 minutes is reached, and based on the input signal from the input means 14a, the right hour key 8f. When the pressing of is detected, the time digit of the set time is changed from 0 to 9 in increments of 1 hour. When the pressing of the right minute key 8g is detected, when the time digit is 0, the minute digits are incremented by 1 to 20 minutes. Change from 20 minutes to 55 minutes in 5 minute increments. If the time digit is 1 or more, change the minute digits in 5 minute increments. When the mode control means 16a detects that the right hour key 8f or the right minute key 8g continues to be pressed, the mode control means 16a accepts it again after 1.2 seconds, and once every 0.2 seconds thereafter. Accept one by one. Further, when the pressing of the right cancel key 8h is detected, the timer function is canceled.

  Similarly, the mode control means 16b has a timer function for turning off the output of the left induction heating means 2 when the set time from 1 minute to 9 hours and 55 minutes is reached, and based on the input signal from the input means 14b, When the pressing of the hour key 9f is detected, the time digit of the set time is changed from 0 to 9 in increments of 1 hour, and when the pressing of the left minute key 9g is detected, the minute digit 1 to 20 minutes is 1 when the time digit is 0. Minute increments are from 20 to 55 minutes, and when the hour digit is 1 or more, the minute digit is changed in 5 minute increments. When the mode control means 16b detects that the left hour key 9f or the left minute key 9g is continuously pressed, the mode control means 16b accepts it again after 1.2 seconds, once, and thereafter every 0.2 seconds. Accept one by one. Further, when the pressing of the left cancel key 9h is detected, the timer function is canceled.

  Similarly, the mode control means 16c has a timer function for turning off the output of the roaster heating means 3 when the set time from 1 minute to 30 minutes is reached, and based on the input signal from the input means 14c, the roaster minute key 10g. When pressing of is detected, the time is changed in increments of 1 minute from 0 to 30 minutes. When the mode control means 16c detects that the roaster key 10g is continuously pressed, the mode control means 16c accepts it once again after 1.2 seconds, and accepts it once every 0.2 seconds. In addition, when the pressing of the roaster cancel key 10h is detected, the timer function is canceled.

  Next, the operation and action of the key press abnormality detection means 15a, 15b, 15c in each mode control means 16a-16c will be described.

  The key long press detection means 15a detects abnormal key presses for the right hour key 8f and the right minute key 8g in the touch keys 13 from the right turn / on key 8c to the fried food cut / on key 8i detected by the input means 14a. For other keys, if the key pressing state continues for 3.0 seconds or longer, it is detected that the key has been pressed abnormally. The mode control means 16a turns off the output of the right induction heating means 1 when an abnormality is detected based on the input signal from the key long press abnormality detection means 15a, and displays that the abnormality is detected by the right display means 8a. I do.

  More specifically, as shown in FIG. 4, when the key long press abnormality detecting means 15a starts its operation, it initializes a timer for counting the key long press for 3.0 seconds at 401 and starts counting. Based on the input signal from the input means 14a at 402, the pressing state of the key from the right turn / on key 8c to the fried food cutting / on key 8i is detected. If no key is pressed, the process branches to 401. . Even when one of the keys is pressed, if the right hour key 8f or the right minute key 8g is pressed alone at 403 and 404, the process branches to 401.

  With the above configuration, when the right hour key 8f or the right minute key 8g is pressed alone, the key long press abnormality detecting means 15a does not detect abnormality.

  However, if the key press is not the right key 8f or the right minute key 8g, the process branches to 405. If the key press continues for 3.0 seconds or more, the process branches to 406 and a signal indicating abnormal key press is indicated. Output to the mode control means 16a.

  When the mode control means 16a receives the signal indicating the key press abnormality from the key long press abnormality detecting means 15a while controlling the right induction heating means 1 with a predetermined output, the output of the right induction heating means 1 is output. Is turned off, and the right display means 8a visually notifies that any of the keys on the right induction heating operation display section 8 is abnormal, and the notification means 17 makes an auditory notification.

  Similarly, the key long press abnormality detecting means 15b does not detect the key long press abnormality when only the left key 9f is pressed or only the left minute key 9g is pressed. If the operation continues for a long time, an abnormal key press is detected, and the mode control unit 16b detects an abnormality based on a signal input from the key press abnormal detection unit 15b to turn off the output of the left induction heating unit 2 and the left induction heating operation. The left display means 9a visually notifies that any of the keys on the display unit 9 is abnormal, and the notification means 17 performs auditory notification.

  Similarly, the key press abnormality detecting means 15c does not detect the key long press abnormality when only the roaster left minute key 10g is pressed, and otherwise the key long press abnormality is detected if the key press state continues for 3.0 seconds or more. The mode control unit 16c detects an abnormality based on a signal input from the key long press abnormality detection unit 15c to turn off the output of the roaster heating unit 3, and any of the keys on the roaster operation display unit 10 is detected. Annunciation of abnormality is visually performed by the roaster display means 10a, and auditory is performed by the notification means 17.

  As described above, according to the present embodiment, since the key long press abnormality is not detected for the key for setting the timer time, it is easy to use a key repeat function for a desired one from a large number of settings in a short time. For other keys, put the pan on top of the key, or if the key in the pan is accidentally received due to spilling water, etc. Even when the output amount is changed, it is possible to detect an abnormal key press after 3.0 seconds and stop the output of the heating means, thereby improving the safety of the device when the user is not nearby.

  In this embodiment, the time for detecting abnormal key presses is set to 3.0 seconds, but the same effect can be obtained by setting other values depending on the time from key press to reception. .

(Embodiment 2)
FIG. 5 shows a heating cooker according to the second embodiment of the present invention, and shows the operation of the key long press abnormality detecting means. Since the basic configuration is the same as that of the first embodiment, the description thereof is omitted.

  In the present embodiment, the difference from the first embodiment is that when the key press abnormality detecting means 15a presses only the right hour key 8f or the right minute key 8g, the key press continues for 12.0 seconds. When an abnormality is detected and the other key is pressed, the abnormality is detected when the key is pressed for 3.0 seconds. Further, the key long press abnormality detecting means 15b detects an abnormality when the key is continuously pressed for 12.0 seconds when only the left key 9f is pressed or only the left minute key 9g is pressed, and when the other key is pressed, the key is pressed. Is detected for 3.0 seconds. Furthermore, the key long press abnormality detecting means 15c detects an abnormality when the key press continues for 12.0 seconds when only the roaster key 10g is pressed, and abnormal when the key press continues for 3.0 seconds in the case of other key presses. This is to detect it.

  About the cooking-by-heating machine comprised as mentioned above, operation | movement and an effect | action of a key long press abnormality detection means are demonstrated.

  As shown in FIG. 5, when the key long press abnormality detecting unit 15a starts to operate, a timer for measuring the key long press time is initialized at 501 and starts counting. Then, at 502, based on the input signal from the input means 14a, the pressing state of the right turn / on key 8c to the fried food cutting / on key 8i is detected, and if no key is pressed, the process branches to 501. .

  However, if any key is pressed, if the right hour key 8f or the right minute key 8g is pressed independently at 503 and 504, the process branches to 507, and the key press continues for 12.0 seconds. The process branches to 506 and a signal indicating an abnormal key press is output to the mode control means 16a.

  If the key press is not the right key 8f or the right minute key 8g, the process branches to 505. If the key press continues for 3.0 seconds or more, the process branches to 506 and a signal indicating abnormal key press is indicated. Output to the mode control means 16a.

  The mode control means 16a turns off the output of the right induction heating means 1 when receiving a signal indicating a key long press abnormality from the key long press abnormality detecting means 15a while the output control of the right induction heating means 1 is being performed. At the same time, a notification that any of the keys on the right induction heating operation display unit 8 is abnormal is visually performed by the right display means 8 a and auditoryly performed by the notification means 17.

  In addition, when the left key 9f is pressed down or the left minute key 9g is pressed down, the key long press abnormality detecting means 15b continues for 12.0 seconds, or the other key pressed state is 3.0. If it continues for more than 2 seconds, the key long press abnormality is detected, and the mode control means 16b detects an abnormality based on the signal input from the key long press abnormality detection means 15b and turns off the output of the left induction heating means 2, and the left induction heating. The left display means 9a visually notifies that any of the keys on the operation display unit 9 is abnormal, and the notification means 17 performs auditory notification.

  Similarly, the key press abnormality detecting means 15c determines that the key pressing state continues for 12.0 seconds when only the roaster left minute key 10g is pressed, or the other key pressing state continues for 3.0 seconds or more. The long control abnormality detection is performed, and the mode control means 16c detects an abnormality based on the signal input from the key long press abnormality detection means 15c to turn off the output of the roaster heating means 3, and the key on the roaster operation display unit 10 is detected. A notification that any of them is abnormal is visually performed by the roaster display means 10a and auditoryly performed by the notification means 17.

  As described above, in this embodiment, the time until an abnormality is detected with a key having a key repeat function is longer than the time until an abnormality is detected with another key, and can be almost normal operation. By setting the time to no time, abnormal detection is not performed by normal key operation, and the key press state is abnormal because the pan is placed on the key having the key repeat function or the food in the pan is blown out. In such a state that continues for a long time, the output of the right induction heating means 1, the left induction heating means 2, or the roaster heating means 3 can be stopped to improve the safety of the device when the user is not nearby. it can.

  Further, when an abnormality is detected with a key that does not have a key repeat function, the output of the right induction heating means 1, the left induction heating means 2, or the roaster heating means 3 can be quickly stopped in a relatively short time.

  In this embodiment, the time until an abnormality is detected with a key having a key repeat function is 12.0 seconds, but if the time is longer than the time until an abnormality is detected with a key having no key repeat function, The same effect can be obtained even if other numerical values are set according to the number of settings to be changed by the key repeat function and the key repeat cycle.

(Embodiment 3)
FIG. 6 shows a heating cooker according to Embodiment 3 of the present invention, and shows the operation of the key long press abnormality detecting means. Since the basic configuration is the same as that of the first embodiment, the description thereof is omitted.

  In the present embodiment, the difference from the first embodiment is that when the key press abnormality detecting means 15a presses only the right key 8f or only the right minute key 8g, an abnormality occurs when the repeat enters the third round. In the case of detection and other key presses, an abnormality is detected if the key press continues for 3.0 seconds. Further, the key long press abnormality detecting means 15b detects an abnormality when the repeat enters the third round when only the left key 9f is pressed or only the left minute key 9g is pressed, and the key is pressed when other keys are pressed. Abnormality is detected after continuing for 3.0 seconds. Further, the key long press abnormality detecting means 15c detects an abnormality when the repeat key enters the third round when only the roaster key 10g is pressed, and detects an abnormality when the key is continuously pressed for 3.0 seconds. This is what I did.

  About the cooking-by-heating machine comprised as mentioned above, operation | movement and an effect | action of a key long press abnormality detection means are demonstrated.

  As shown in FIG. 6, when the key long press abnormality detecting means 15a starts operating, a timer for measuring the key long press time is initialized at 601 and starts counting. Based on the input signal from the input means 14a at 602, the pressing state of the right turn / on key 8c to the fried food cutting / on key 8i is detected. If no key is pressed, the process branches to 601. .

  However, if any key is pressed, if the right key 8f or the right minute key 8g is pressed alone at 603 and 604, the process branches to 607, and the right key 8f accepts the key. Return to the setting when the time digit of the timer time starts the key reception, with the right minute key 8g, the key is accepted and the setting returns to the setting when the minute digit of the timer time starts the key reception. If it is executed once, the process branches to 606, and a signal indicating an abnormal key press is output to the mode control means 16a.

  If the key press is not the right key 8f or the right minute key 8g, the process branches to 605. If the key press continues for 3.0 seconds or more, the process branches to 606 to indicate a signal indicating an abnormal key press. It outputs to the control means 16a.

  The mode control means 16a turns off the output of the right induction heating means 1 when receiving a signal indicating a key long press abnormality from the key long press abnormality detecting means 15a while the output control of the right induction heating means 1 is being performed. At the same time, a notification that any of the keys on the right induction heating operation display unit 8 is abnormal is visually performed by the right display means 8 a and auditoryly performed by the notification means 17.

  Further, the key long press abnormality detecting means 15b determines that the key repeats three times when only the left hour key 9f is pressed or only the left minute key 9g is pressed, or when the other key pressed state continues for 3.0 seconds or more. The mode control means 16b detects an abnormality based on a signal input from the key long press abnormality detection means 15b and turns off the output of the left induction heating means 2 and displays the left induction heating operation display unit 9 on the left induction heating operation display unit 9. A notification that any one of the keys is abnormal is visually performed by the left display means 9a, and is acoustically performed by the notification means 17.

  Similarly, the key long press abnormality detecting means 15c detects the key long press abnormality when the repeater makes three rounds when only the roaster left minute key 10g is pressed, or when the other key pressed state continues for 3.0 seconds or more. The mode control means 16c detects an abnormality based on the signal input from the key long press abnormality detection means 15c and turns off the output of the roaster heating means 3, and any of the keys on the roaster operation display unit 10 is abnormal. A notification to that effect is made visually by the roaster display means 10 a and is made auditory by the notification means 17.

  As described above, in the present embodiment, the time until an abnormality is detected with a key having a key repeat function is longer than the time until an abnormality is detected with another key, and is changed by the key repeat function. By associating with the number of times that one round is taken, the time until the key is pressed and the abnormal state is detected when the pan is placed on the key having the key repeat function or the food in the pan is blown out, In addition to being able to set a set number of rounds that cannot be performed by a normal key repeat operation, it is possible to flexibly cope with changes in the number of settings and the key repeat cycle that are changed by a key having the key repeat function.

  Further, when an abnormality is detected with a key that does not have a key repeat function, the output of the right induction heating means 1, the left induction heating means 2, or the roaster heating means 3 can be quickly stopped in a relatively short time.

  In this embodiment, the number of repeats until an abnormality is detected with a key having a key repeat function is set to three. However, if it is longer than the time until an abnormality is detected with a key having no key repeat function, 2 repeats. The same effect can be obtained even if the number of times is different, such as a round or four rounds.
