Description

  The present invention relates to a cooking device that sets a timer by an input of an operation unit and automatically ends heating when a set time is reached.

Conventionally, this type of cooking device changes the timer cooking time each time the timer key is operated, and can change from the minimum cooking time to the maximum cooking time. When the timer key is operated with the maximum cooking time set, the timer cooking is canceled or the minimum cooking time is restored. (For example, see Patent Document 1)
Japanese Patent No. 3264235

  However, in the conventional configuration, when the timer cooking setting time is long, and the timer key must be operated many times when setting the maximum cooking time, the timer cooking is quickly repeated to make the timer cooking. There was a problem that time was canceled or it returned to the minimum cooking time and was unusable. Further, even in the configuration in which the timer cooking time is continuously changed by continuously pressing the timer key, there is a similar problem if the release of the timer key is delayed.

  In addition, in the configuration where heating is terminated after a certain time has elapsed since the start of heating regardless of the setting of the timer cooking time, if the timer cooking time is set after starting cooking, if the set time is large, The time from the start of heating to the end of timer cooking may exceed the heating end time for safety.For example, in the case of a gas cooker, there is a problem that the surroundings may be abnormally heated and dangerous. It was.

  This invention solves the said conventional subject, and it aims at providing a cooking device which is easy to use and has a safe timer cooking function.

  In order to solve the above-described conventional problems, the cooking device of the present invention has a maximum cooking time with a different notification pattern from the time of accepting a normal timer cooking time change when the maximum cooking time is reached by operating a timer key. It is intended to notify that it has been set. In addition, even in a configuration in which the timer cooking time is continuously changed by continuously pressing the timer key, the timer cooking time is continuously changed when the maximum cooking time is reached even if the timer key is kept pressed, and the maximum cooking time is similarly set. It is assumed that the time has been set.

  As a result, it is possible to easily set a long timer cooking time by avoiding erroneously canceling the timer cooking time or returning to the minimum cooking time by excessively operating the timer key in an attempt to set the maximum cooking time. .

  In addition, the heating cooker of the present invention is configured to end heating after a certain period of time from the start of heating for safety regardless of whether the timer cooking time is set or not, and when the timer cooking time is set after starting cooking Since the maximum cooking time that can be set so that the time from the start of heating to the end of timer cooking does not exceed the heating end time for safety is changed, for example in the case of a gas cooker, the surroundings are abnormally heated It can prevent becoming unsafe.

  The heating cooker of the present invention can easily set the timer without erroneous operation even when the timer key has to be operated many times when setting the maximum cooking time.

  1st invention is the control means which controls the output of a heating part, the operation part which has an input device, and the cooking time change means which sets and changes the time of timer cooking according to the command input with the input device of an operation part And a display means for displaying the cooking time changed by the cooking time changing means and a notifying means for notifying when an effective operation is performed, and the cooking time changing means detects that the maximum cooking time has been set. Then, by notifying the fact that the maximum cooking time has been set with a notification pattern that is different from the normal cooking time change, the timer key is erroneously operated by trying to set the maximum cooking time and trying to set the maximum cooking time. The cooking time is not canceled or returned to the minimum cooking time, and a long timer cooking time can be easily set.

  In the second invention, in particular, in the cooking time changing means of the first invention, when the timer cooking time is continuously changed by continuously pressing the timer key, the maximum cooking time is reached even if the timer key is kept pressed. Sometimes, by stopping the continuous change of the timer cooking time and notifying that the maximum cooking time has been set by the notification means, it is delayed to release the timer key, accidentally canceling the timer cooking time or returning to the minimum cooking time The long timer cooking time can be easily set.

  In the third invention, in particular, when the control time of the first invention or the second invention reaches a certain cooking time, regardless of the setting of the timer cooking time by the operation of the user, it is for safety. Maximum cooking time that can be set to a value that does not exceed the safe heating time when the timer cooking time is set or changed after cooking starts and the timer cooking time is set or changed after cooking is started. By changing the, it is possible to prevent an unsafe operation because a long-time timer setting that causes abnormal heating is not mistakenly performed whenever the user performs a timer operation.

  The fourth aspect of the invention is the maximum cooking time that can be set not to exceed the safe heating time when the timer cooking time is changed after the start of cooking, in particular, the control means of any one of the first to third aspects of the invention. When changing, even if the maximum cooking time is between time units changed by one change operation, the maximum value that does not exceed the time unit and the time from the start to the end of the timer cooking does not exceed the safe heating time is maximized By displaying and informing as the cooking time, the user can know the exact remaining time, and it is possible to provide a heating cooker with a timer cooking function that is easy to use while considering safety.
