Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a configuration for controlling an interrupt from an external abnormality detection sensor of a cooking device, which is equipped with a display means for displaying cooking information and a sound generation means.

Conventionally, in abnormality alarm systems such as fire or gas leak, when a corresponding abnormality is detected at an individual installation location, a buzzer, bell, etc. are used to notify surrounding people. Therefore, for example, if this type of abnormality occurs in the home, it is not possible to immediately determine in which room and what kind of abnormality has occurred based on the alarm sound alone, and furthermore, it may be necessary to replace the abnormality alarm device due to improved abnormality detection accuracy. However, they had drawbacks such as the need for periodic inspection and maintenance.

The present invention eliminates such conventional drawbacks, and is capable of displaying the type of abnormal state on the display means when an abnormality is detected from the safety detection means in a cooking apparatus having a display means and a sound generation means. The purpose of this invention is to improve the functionality of a cooking appliance by issuing an abnormality warning via a voice generating means.

To achieve this objective, the present invention inputs an abnormality detection signal from one or more fire, gas, etc. safety detection means, and sends an abnormal state display request signal and an abnormal state warning request signal to a cooking oven controller. The abnormality determining means for outputting to the display controller and the sound generating means, respectively, is detachably connected to the safety detecting means through the display controller.

With this configuration, the abnormality determining means inputs the abnormality detection signal from the safety detection means and sends an abnormal state display request signal and an abnormal state warning request signal to the cooking oven controller. The cooking oven controller sends a signal (hereinafter referred to as an access signal) to the display controller requesting an abnormal state display according to the abnormality content, and also requests the sound generation means to issue an abnormality warning notification corresponding to the abnormality content. A signal (hereinafter referred to as an access signal) is sent. The display controller outputs abnormal state display data to the display means. The audio generation means outputs an abnormality warning notification via a speaker.
