Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric cooker such as an electric hob used in general households.

[0002]

[Prior Art]

 Demand for this type of electric cooker is growing year by year because it is safer than a gas stove, but in order to further enhance safety when cooking with oil such as tempura However, it can be seen that the temperature can be automatically adjusted and the oil is not heated to a certain temperature or higher (see, for example, JP-A-2-279925).

[0003]

[Problems to be solved by the device]

 However, this automatic temperature control function is also not perfect, and there are restrictions such as not operating when the amount of oil is small, and the oil temperature rises, which may cause a fire or a fire accident. There is.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and when a person stays away from the vicinity of the cooking device for a certain period of time during cooking, the human body detection unit detects the sound and notifies the sound by the notification unit, and the heater is used. To stop energizing.

[0005]

[Action]

 With the above configuration, when a person leaves the cooker main body for a certain period of time while cooking oil such as tempura, the human body detection unit detects that there is no person, and a warning is issued by a notification means that sounds a voice. However, the heater is automatically de-energized to prevent accidental fire accidents.

[0006]

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 is a main body, 2 is a heater provided on the upper surface of the main body 1, and 3 is an operation panel, which is provided on the front surface of the main body 1 to energize the heater 2 and set electric power. Reference numeral 4 denotes a human body detecting means, which is provided on the front surface of the main body 1 near the operation panel 3 and detects a human body near the main body 1 while the heater 2 is being energized. Reference numeral 5 is a control means constituted by an electronic circuit or the like provided inside the main body 1 for controlling energization of the heater 2 and driving of the human body detecting means 4. The human body detecting means 4 detects a human body near the main body 1. After a certain set time has passed since the time of disappearing, a warning is issued by the notifying means 6 provided inside the main body 1 for generating a voice. The heater 2 is automatically stopped at the same time when a warning is issued, or a warning is issued again, and then the heater 2 is stopped after a set time.

Next, the operation of this embodiment will be described.

FIG. 2 is an operation flowchart. In step 101, the control means 5 confirms whether the heater 2 is energized, and if energized, the process proceeds to step 102.

In step 102, the control means 5 determines whether or not to issue the warning by the notifying means 6, and if the warning is issued, the process proceeds to step 103. If not, the process returns to the first step 101. It will be in a standby state where a warning can be notified.

In step 103, it is determined whether or not there is a warning by the human body detection means 4 and there is a person near the main body 1. If there is a person, the process returns to step 101, and if not, the process proceeds to step 104.

In step 104, a timer that counts the time after the human body detection unit 4 detects the human body is started, and a count of a certain set time set in this timer is performed in step 105. The process proceeds to the subsequent step 106, and the notification means 6 gives a warning by voice. Note that the human body detection is performed by returning to step 103 until a certain set time has elapsed. Therefore, if a person is detected before a certain set time has elapsed, no warning is given.

FIG. 3 is an operation flowchart of another embodiment. After a lapse of a certain set time, the process proceeds to step 106, the notification means 6 gives a voice warning, and the process proceeds to step 107 to turn off the heater 2 by the control means 5. To do. Note that the human body detection is performed by returning to step 103 until a certain set time has elapsed. Therefore, if a person is detected before a certain set time elapses, the warning is not issued and the energization is not stopped.

FIG. 4 is an operation flowchart of yet another embodiment. After a lapse of a certain set time, the process proceeds to step 106, where the notification means 6 gives a voice warning and returns to step 103 until the lapse of a certain set time. Performs human body detection. Next, the routine proceeds to step 107, a timer for counting the time after the warning is issued is started, and a certain set time is counted at step 108, and after a certain set time has elapsed, the routine proceeds to step 109, where the heater is controlled by the control means 5. Turn off 2. It should be noted that the process returns to step 103 and human body detection is performed again until a certain set time has elapsed. Therefore, if the person is detected before a certain set time of the former, a warning is not issued, and if the person is detected before a certain set time of the latter is passed, the energization is not stopped.

Note that the sounding of the notifying means 6 is not limited to the present invention and is not limited to the present invention as long as a warning sound such as a buzzer is emitted.

[0016]

[Effect of the device]

 According to the present invention, when a person leaves the front of the cooker for a certain period of time while cooking oil such as tempura, a warning is given by voice or the heater is automatically energized with the warning. Since the heater is stopped and a warning is given and the heater is automatically de-energized after a certain period of time, it is possible to provide an electric cooker that is extremely safe and can prevent accidental fire accidents. I can.
