Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides an automatic cooking device in which when a setting switch for setting a cooking menu outputs an undefined setting value (a cooking setting value not included in the cooking menu), This invention relates to a safety device for a cooker that notifies the user with a buzzer, provides accurate cooking settings, and improves cooking safety.

Structure of a conventional example and its problems A conventional cooking device of this type will be explained using a gas staple stove as an example in FIG. The ignition switch 1 sends a signal to the control circuit 2 to open the source valve 3, and the linked safety valve 4 opens. The gas passes through the gas pipe and reaches the heating means 5, where it is ignited.

After igniting, automatic cooking is performed by opening and closing the control valve 8 based on the signal from the setting switch 6 that sets the cooking menu and doneness, and the signal from the sensor 7 that indicates the temperature of the food to be cooked. The cooking is completed when the control circuit 2 detects the completion of the cooking.

Cookers generally have the above-mentioned configuration, but since the setting switch 6 for setting the cooking menu and doneness is generally a contact type switch, the moment the setting is changed, it becomes in an undefined setting state (the contact is turned off). oven or close at the same time). The control circuit 2 had a problem in that it malfunctioned due to this undefined set value.

Purpose of the Invention In order to solve all the problems of the conventional art, the present invention, when a control circuit inputs an undefined setting value of a setting switch for setting the cooking menu and cooking condition, sets the previous setting value to the previous setting value when the setting is confirmed. When the undefined set value continues for a certain period of time,
By notifying the user with a buzzer, malfunctions of the cooker can be prevented.

The purpose is to improve safety.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Note that the same members as in FIG. 1 are given the same numbers. The ignition switch 1 causes the control circuit 2 to send a signal to the main valve 3 to open it, and at the same time, the manual safety valve 4 opens. The gas passes through the gas pipe and reaches the heating means 5 and is ignited. After igniting, the control valve 8 is opened and closed according to the cooking menu, a signal from the setting switch 6 for setting the cooking condition, and a signal from the sensor 7, thereby performing automatic cooking. When the control circuit 2 detects the completion of cooking, it sends a close signal to the main valve 3 to close it. When a set value is input to the control circuit 2 from the setting switch 6, the detection unit 9 detects whether or not it is an undefined set value.If it is an undefined set value, the value immediately before the undefined setting was input is stored in the holding unit 10. input. When this undefined setting value is continuously input for a certain period of time, a buzzer circuit 11 notifies the user to prompt the user to reset the setting.

In FIG. 3, the processing when inputting the cooking setting switch will be explained using a flowchart (k). First, input the setting switches.

The cooking menu and doneness of this input value are coded.

If the coded value is an undefined setting value, the value immediately before inputting the undefined setting value is maintained. If an undefined set value is continuously input for a certain period of time, a buzzer will notify the user. If it is not an undefined setting value, read the code. Next, automatic cooking is performed based on the read cooking menu, doneness code, and sensor input values. When cooking is complete, close the main valve to finish cooking. Digital value (discrete quantity) as mentioned above
When inputting a value, a circuit or memory must be used to hold the input value for a certain period of time. This configuration has the effect of notifying the user when an erroneous input is made to a contact type switch such as a cooking setting switch, thereby preventing malfunctions of the control circuit and improving safety. I have explained the gas staple stove above, but electric,
Heating means such as oil may also be used.

Effects of the Invention As described above, according to the cooking device safety device of the present invention, in the case of a contact type switch such as a cooking menu setting switch in a conventional automatic cooking device, the contacts open or simultaneously close, resulting in an undefined set value. was input to the control circuit. Therefore, when an undefined set value is input, the previous set value is retained, and if an undefined set value is input continuously for a certain period of time, a buzzer alerts the user. This has the effect of eliminating cooker failures due to use, preventing flames and the like caused by runaway cookers, and improving safety.

Claims (1)

[Claims] A heating means for heating the food to be cooked, a sensor for detecting the temperature of the food to be cooked, a setting switch for setting the doneness of cooking and cooking content, and a heating means for heating the food depending on the signal of the sensor and the value of the setting switch. It has a control circuit that controls the amount of heating or the heating method, and the control circuit includes a detection unit that detects an undefined set value of the setting switch, and holds the set value immediately before the undefined set value until the set value is determined. A safety device for a cooker that includes a holding part and a buzzer circuit that notifies the user of an undefined set value.
