  • Patent number: 6553895
    Abstract: A brewing apparatus for an electric coffee maker includes a plunger unit and a sleeve unit, which can be driven by a driving unit to move horizontally on a machine base. When an unsealed chamber is defined among a coffee-discharging unit, the plunger unit and the sleeve unit, ground coffee beans can be fed into the unsealed chamber. Subsequently, a sealed chamber is defined among the coffee-discharging unit, the plunger unit and the sleeve unit such that the ground coffee beans are received within the sealed chamber, thereby permitting flow of hot water into the sealed chamber. Finally, the plunger unit and the sleeve unit are separated from the coffee discharging unit, thereby permitting dropping of consumed ground coffee from a space between the coffee-discharging unit and the assembly of the plunger unit and the sleeve unit.

  • Patent number: 6546925
    Abstract: A barbecue grill assembly includes a grill member disposed in a cooking base. The cooking base has left and right side walls extending upwardly from a bottom wall. Atop cover is disposed on a top side of the cooking base for covering the cooking base. A side rack has one end portion pivoted to one of the left and right side walls of the cooking base. The side rack is turnable inwardly into the cooking base for moving to a folded position, and is further turnable outwardly from the cooking base for moving to an unfolded position. A fastening unit fastens releasably the top cover and the cooking base when the side rack is disposed at the folded position.

  • Publication number: 20030037781
    Abstract: A barbecue grill assembly includes a main frame mounted with a plurality of mounting seats, and a plurality of leg members with tubular upper end portions. Each of the mounting seats has a downwardly extending cylindrical coupling portion that is formed with a radial retaining pin. The upper end portion of each of the leg members is sleeved on the coupling portion of a respective mounting seat, and is formed with a retaining slot that includes a slide section extending downwardly from an upper edge of the leg member, and a locking section extending transversely from the slide section. The retaining pin is slidable along the slide section when the leg member is sleeved onto the respective mounting seat, and engages the locking section when the leg member is rotated subsequently and axially about the respective mounting seat, thereby retaining the leg member on the respective mounting seat.

  • Publication number: 20030034024
    Abstract: A barbecue grill assembly includes aside rack mounted foldably on a main frame, which has a mounting seat formed with an insert hole for access to a slide passage and installed with a resilient locking pin and an operating shaft coupled to the locking pin. The side rack has an insert rod extending slidably into the slide passage and formed with an engaging groove for engaging the locking pin so as to retain the side rack at a horizontal unfolded position. The insert rod extends through a side hole portion of the insert hole when in the unfolded position. The operating shaft is operable against restoring action of the locking pin so as to disengage the locking pin from the insert rod. The insert rod is slidable outwardly and is turnable downwardly to extend through a bottom hole portion of the insert hole when disengaged from the locking pin.

  • Patent number: 6513515
    Abstract: A barbecue grill assembly includes a cook unit and a casing. The cook unit has a cooking base, a grill member disposed in the cooking base, a top cover, and a handle formed on the top cover. The casing includes front and rear casing parts that have first edges hinged to each other, and second edges fastened releasably to each other by a pair of fastening units. The casing is formed with two handle openings at the second edges, and is mounted with a wheel unit and a pull member above the wheel unit. The casing confines a receiving space for receiving the cook unit. The handle on the cook unit is extendible through the handle openings. The pull member is operable for pulling the casing to move along a ground surface by virtue of rolling contact of the wheel unit with the ground surface. The casing is adapted to be disposed uprightly on a ground surface for supporting the cook unit thereon.

  • Patent number: 6484624
    Abstract: A grill device includes an upper grill unit pivoted to a lower grill unit so as to rotate about an axis between an open position, and a closed position, in which, the upper and lower grill units cooperatively define a cooking space therebetween. A seasoning supplying unit includes a vessel mounted in the cooking space to receive a body of seasonings in liquid form, and a thermal conductive dispenser. The thermal conductive dispenser is extendible into the vessel when the upper grill unit is positioned at the closed position, and defines a plurality of channels. Each of the channel has an inlet that is immersed in seasonings in the vessel, and an outlet that is exposed from the vessel when the upper grill unit is positioned at the closed position.

  • Patent number: 6472644
    Abstract: A grill device includes a horizontal upper grill which is superposed on a lower grill unit and which has an upper cooking member and an insulated terminal-mounting seat. The terminal-mounting seat has first and second terminals electrically coupled with the upper cooking member and a ground terminal hole. A spring-biased blocking plate is mounted on the terminal-mounting seat in such a manner to deny access into the ground terminal hole in the terminal-mounting seat when the upper grill unit is separated from the lower grill unit. A push plate with a through hole is fixed on the lower grill unit, and pushes the blocking plate away from the ground terminal hole when the upper grill unit is superposed on the lower grill unit, thereby establishing spatial communication between the through hole in the push plate and the ground terminal hole in the terminal-mounting seat.
