  • Switch control device and method, and heating cooker having the control device
    Patent number: 6624395
    Abstract: The present invention provides a device for signal control of a switch which outputs a first signal in response to a turning operation thereof and outputs a second signal in response to a depressing operation thereof. If one of the first and second signals is outputted in response to a corresponding one of the switch turning operation and the switch depressing operation and the other signal is thereafter outputted in response to the other operation within a predetermined period, the control device nullifies the other signal. With this arrangement, a heating cooker provided with the switch is prevented from performing an under-heat or over-heat cooking operation on the basis of a misoperation of the switch. Further, the need for resetting a cooking period is obviated which may otherwise arise from the misoperation of the switch.
