  • Patent number: 11214875
    Abstract: The present invention provides a gas generator and comprises an electrolysis device, a water supplying device, and a liquid level detector. The electrolysis device is configured for electrolyzing water to generate hydrogen. The water supplying device is coupled to the electrolysis device for supplying the supplementary water into the electrolysis device. The liquid level detector is coupled to an outer surface of the electrolysis device for detecting a liquid level of the electrolyzed water, wherein the gas generator supplies supplementary water into the electrolysis device according to the liquid level detected by the liquid level detector. The present invention is provided for measuring the liquid level by using the non-contact liquid level detector, and supplying supplementary water into the electrolysis device according to the liquid level to ensure that the electrolysis device contains sufficient water for electrolyzing, thereby improving the life and safety of the gas generator.

  • Patent number: 9386635
    Abstract: The disclosed induction heating cooking device includes a boiling-over detection portion which is adapted to reduce heating output from an inverter to a pre-set value if the amount of change of a capacitance detected by a capacitance detection portion from a reference value (Vo) is equal to or more than an output reduction threshold value (?V2), and further is adapted to stop heating, if the amount of change is equal to or more than an output stop threshold value (?V3). In this case, the output stop threshold value is provided for each of the plurality of the electrodes, which can absorb impedance variations in the plurality of the electrodes formed through pattern printing using conductive films, thereby uniformizing their sensitivity to boiling over in any directions.

  • Patent number: 8373099
    Abstract: A fuel cell is provided to furnish electrical power to an HVAC&R system, and the waste heat from the fuel cell is transferred to a secondary fluid directed to flow to the climate-controlled space of a building during periods of time in which heating is required. The heat rejected by the fuel cell may be a supplemental or primary source of heat as well used for precise temperature control within the climate-controlled space of the building. A channeling assembly is used to selectively direct the fuel cell heat either to and/or away from the climate-controlled space served by the HVAC&R system. Higher energy efficiencies of the HVAC&R equipment are achieved, and the “cold blow” phenomenon is reduced or eliminated.
