  • Patent number: 6824303
    Abstract: An apparatus for blending and for making ice cream includes drive, blending, and stirring units. The drive unit includes a high-speed output gear unit driven rotatably by a drive shaft and formed with a first engaging hole that extends along a rotary axis, a speed-reduction gear unit driven rotatably by the drive shaft, and a low-speed output gear unit driven rotatably by the speed-reduction gear unit and formed with a second engaging hole that is coaxial with the first engaging hole. The blending unit engages removably the first engaging hole and is driven by the drive unit to rotate about the rotary axis at a higher speed. The stirring unit engages removably the second engaging hole and is driven by the drive unit to rotate about the rotary axis at a lower speed.

  • Patent number: 6418276
    Abstract: A method for heating water rapidly at low power requirement includes the steps of (1) energizing and heating a heating element of a first heating device for a first period; (2) simultaneously de-energizing the heating element of the first heating device, forcing cold water to flow from a first reservoir to a second reservoir via the first heating device such that the cold water is heated to form warm water, and energizing and heating a heating element of a second heating device for a second period; and (3) simultaneously de-energizing the heating element of the second heating device and forcing the warm water from the second reservoir into the second heating device such that the warm water is heated to form hot water.

  • Patent number: 6276263
    Abstract: A grill device includes a horizontal upper grill unit with a rear side, a horizontal lower grill unit with a rear side, and a connecting unit. The upper grill unit is superposed on the lower grill unit. The connecting unit interconnects the rear sides of the upper and lower grill units in such a manner that the upper grill unit can be turned rearward from the lower grill unit to a half-open position and to a horizontal fully-open position. When turned to the half-open position, the upper grill unit is retained automatically thereat unless it is pulled upwardly relative to the lower grill unit.

  • Patent number: 6269738
    Abstract: A grill device includes an annular bottom wall adapted to be placed above a flat support, and outer and inner annular walls which extend uprightly from outer and inner annular peripheries of the bottom wall to form outer and inner upper annular edges and which cooperate with the bottom wall to confine an annular fluid collecting groove. A lower cooking member includes upper and lower major walls normal to a central line. The upper major wall includes an outer circumferential area integrally formed with and extending inwardly from the upper inner annular edge, and a central area that is raised so as to be higher than the outer circumferential area. The lower major wall is punched upwardly to form a plurality of first and second ridge portions respectively in the central and outer circumferential areas. The first and second ridge portions are of such heights so that the respective first ridge portion is not higher than the respective second ridge portion.

  • Patent number: 6250794
    Abstract: An agitator for an ice cream making apparatus includes a shaft defining a vertical axis, left and right arms, a primary blade member, diametrically opposed left and right limbs, an extruding screw member, and an auxiliary blade member disposed above the primary blade member. The primary blade member is rotatable relative to the auxiliary blade member, which is held fast when the shaft rotates.

  • Patent number: 6205806
    Abstract: An ice cream making apparatus and an agitator for the same. The agitator includes top and bottom ends, and a shaft defining an axis through top and bottom ends thereof. A pair of first left and right arms are mounted on the shaft adjacent to the top end. A pair of second left and right arms are mounted on the shaft adjacent to the bottom end. A first left wing extends downwardly from a bottom side of the second left arm in a direction substantially parallel to the axis, and a first right wing extends downwardly from a bottom side of the second right arm, and is inclined at an angle relative to the axis. Diametrically opposed third left and right arms interconnect the first and second left arms and the first and second right arms, respectively. A pair of second left and right wings extend inclinedly from the third left and right arms, respectively.

  • Patent number: 6089747
    Abstract: An ice cream making apparatus includes an inner container having a first bottom formed with a first bottom opening, and an outer container surrounding the inner container to confine a coolant storing space therebetween. The outer container has a second bottom formed with a second bottom opening, and an outer rim extending along and upwardly from the second bottom opening. The outer rim has a shoulder extending radially and inwardly therefrom adjacent to the first bottom opening and confronting the first bottom of the inner container. A sealing ring is disposed between the shoulder and the first bottom of the inner container. A hollow tightening member extends through the first and second bottom openings, and abuts against the first bottom of the inner container and the outer rim so as to press the shoulder and the first bottom of the inner container to abut tightly against the sealing ring for preventing coolant from leaking out from the coolant storing space.

  • Patent number: 6085645
    Abstract: An ice cream making apparatus includes a container having a bottom opening for passage of ice cream, and a discharging mechanism mounted on the container below the bottom opening and adapted to discharge ice cream out of the container. The discharging mechanism has a hollow guide which is mounted on the container and which defines a passageway therein for communication with the bottom opening, a gate member disposed underneath the passageway and mounted slidably on the hollow guide for moving in a transverse direction across the passageway to seal the passageway, and a linkage mechanism pivotally mounted on the hollow guide for rotating about an axis to manipulate movement of the gate member in the transverse direction.

  • Patent number: 6029564
    Abstract: A combined baker and ice cream maker includes a base plate, a barrel-receiving container, and a bread baking unit and an ice cream making unit which are to be selectively received in the container. Each of the bread baking unit and the ice cream making unit has a bottom mounting portion. A heater is disposed inside the container. A barrel seat is mounted on the base plate for selectively seating the bread baking unit and the ice cream making unit thereon. A shaft extends through the base plate into the barrel seat. A driving unit is mounted on the base plate, and is connected to the shaft. A switch is mounted on the base plate, and is connected to the heater. A lever is pivotally mounted on the base plate and has opposite first and second ends. The first end extends to the switch, while the second end extends to the barrel seat.
