  • Patent number: 6762975
    Abstract: A control circuit of a programmable coffee maker includes an input unit for inputting a preset brewing time, a heater controller for controlling electrical connection between an electric heating device and a power supply, a sensor unit for providing a cancel signal when temperature at a supply pipe connected to a water reservoir and heated by the heating device reaches a predetermined critical temperature, and a processor having an internal clock with a current time output. The processor controls the heater controller to make electrical connection between the heating device and the power supply when the preset brewing time coincides with the current time output, and cancels the preset brewing time and controls the heater controller to break the electrical connection between the heating device and the power supply after the processor receives the cancel signal from the sensor unit.

  • Patent number: 6739329
    Abstract: A barbecue device includes a support unit with opposite first and second connecting rods that interconnect U-shaped first and second support members, and a cook unit supported removably on horizontal bars of the support members. The support unit is turnable upside-down, and confines a receiving space which opens upwardly when turned upside-down for receiving the cook unit therein. A looped retainer frame is pivoted to the second connecting rod, and engages releasably the first connecting rod. The retainer frame is turnable away from and toward the horizontal bars for moving between an open position, in which the cook unit can be placed in the receiving space, and a closed position, in which the retainer frame engages releasably the first connecting rod for retaining the cook unit in the receiving space.

  • Patent number: 6701826
    Abstract: An electric coffee maker includes a removable filtering member for receiving ground coffee beans. A selection unit can be actuated to operate the assembly of a water-supplying device, a flow control unit, and a dispensing member in a selected one of a single-stage Espresso coffee mode and a two-stage Americano coffee mode. In the Espresso coffee mode, hot water is supplied into the filtering member via a main water path for discharging brewed coffee. In the Americano coffee mode, hot water is supplied twice. The first supply of the hot water flows into the filtering member via the main water path so as to discharge brewed coffee into a cup. The second supply of the hot water flows into the cup via a secondary water path and a water passage space in the dispensing member that is located outside the filtering member.

  • Patent number: 6571687
    Abstract: An electric toaster includes a power switch unit driven by an electromagnet, for holding a spring-loaded carriage mounted in a toasting compartment when the carriage is moved from an upper position to a lower position, so as to switch from an OFF-mode, where the electromagnet is disposed in a deactivated position, to an ON-mode, where the electromagnet is disposed in an activated position. A control unit enables the electromagnet to be excited when the carriage is moved from the upper position to the lower position so as to attract the carriage such that the electromagnet subsequently moves with the carriage from the deactivated position to the activated position.

  • Patent number: RE40285
    Abstract: A grill device includes two independently controllable cooking sets confining two isolate cooking spaces such that two different meat pieces can be grilled therein under different cooking temperatures at the same time. Each of the cooking sets has a cooking plate provided with first and second grill ribs alternately disposed thereon. The first grill rib has a horizontal flat portion and a curved portion extending curvedly and downwardly from the flat portion. The second grill rib has a horizontal flat portion, and a curved portion extending curvedly and upwardly from the flat portion. The curved portion of the second grill rib has an elevation higher than those of the flat portions of the first and second ribs to prevent sliding out a meat piece from the cooking plate when the meat piece is disposed on the flat portions of the first and second grill ribs.
