  • Publication number: 20100219974
    Abstract: Disclosed is a system for interrupting an electric power of an outlet or closing a gas valve through detection of the absence of a user. The system includes a signal transmission device installed on an outside of the outlet and a gas valve device. The signal transmission device detects the existence of the user to output the gas valve device receive the control signal to control the flow of connected to signal an electric power or gas.

  • Publication number: 20100050882
    Abstract: A water-cooled barbecue system which prevents overheating of the interior thereof and a grill and also prevents leakage of water from the appliance when the operation thereof is stopped. A burner is within the main body, a grill is disposed on the upper part of the main body, water circulates in the interior of the grill, and a cooling system for cooling water is included in the barbecue system. A bimetal switch interrupts power to a solenoid gas valve at a predetermined temperature. A fan introduces outer air into the main body's interior and the bimetal switch supplies power to the fan when a predetermined temperature is sensed. A thermal sensor is mounted on a liquid pipe through which water flows out from the grill, and a micom receives data from the thermal sensor and outputs a control signal to the cooling system and the solenoid gas valve.

  • Patent number: 7504745
    Abstract: Disclosed is a multifunctional multi-tap (concent) of intercepting a stand-by electric power and a control method employing the same which prevent big fire generated by leakage current by performing an interlocking control and a single-acting control (separate control) in accordance with subordination of respective appliances using a illumination sensor or a body-detecting sensor. The multifunctional multi-tap (concent) detects a signal according, to an illuminance and a motion of body around respective lead-in holes activated as an interlocking control and a single-acting control using an illumination sensor or a body-detecting sensor, discriminates the detected signal by a controller, and controls the respective appliances as a stand-by state or a power-saving state in accordance with the interlocking control or the single-acting control.

  • Patent number: 6405639
    Abstract: A meat roaster capable of preventing meat from burning and sticking to a grill is provided. The meat roaster includes a body having an accommodating portion for accommodating a heat source. A grill connected to the body includes a frame and a fluid circulating pipe. The pipe is mounted at one side of the frame in such manner that the pipe is repeatedly bent at regular intervals. The pipe has an inlet socket formed at one end of the pipe and an outlet socket at the other end of the pipe. A temperature controller controls a fluid circulating through the pipe of the grill at a predetermined temperature which prevents the grill from overheating.
