  • Patent number: 7743698
    Abstract: A fountain for heating and/or cooling a beverage comprises one or more heating and/or cooling elements that are configured to adjust a temperature of a beverage that circulates through the fountain. In one embodiment, the beverage fountain includes one or more heating elements located proximate to a basin, a cylinder, and/or a top reservoir of the fountain. In another embodiment, the beverage fountain includes one or more cooling elements located proximate to a basin, a cylinder, and/or a reservoir of the fountain. Alternatively, the beverage fountain may include both heating and cooling elements located proximate to a basin, a cylinder, a reservoir, and/or other locations of the fountain, wherein a selection device, such as an electrical switch or control module, may be adjusted by a user in order to select heating or cooling of the beverage.

  • Publication number: 20080179422
    Abstract: A fountain for heating and distributing fluidic material is manufactured using various processes and materials. In one embodiment, the fountain includes a heating element encased in an enclosure. A basin containing a medium, such as chocolate, is removably mounted to the enclosure so that the basin is heated by contact with the enclosure. Additionally, an auger having a spiral flight rotates and lifts the melted chocolate upward to a top end of a cylinder that houses the auger. One or more tiers may be mounted, using various locking mechanisms, onto the cylinder to divert flow of the medium. A smaller chocolate fountain that may advantageously be more suitable for home use is also described herein.

  • Publication number: 20080111002
    Abstract: A chocolate fountain comprises a sleeve secured to a basin of the fountain, the sleeve having a central aperture sized to receive a lower portion of a cylinder so that the cylinder is supported by the sleeve. The sleeve may be attached to the basin by any means, such as via bolts that are integrally coupled to the sleeve. In this embodiment, a portion of the bolts extends through apertures in the basin and coupling devices, such as nuts, are attached to the bolts in order to secure the sleeve to the basin. Advantageously, the aperture of the sleeve is large enough to be easily cleaned and the cylinder does not comprise tubes welded on the side of the cylinder as in currently available chocolate fountains.

  • Patent number: 7182269
    Abstract: A fountain for heating and distributing fluidic material is manufactured using various processes and materials so that the fountain is more easily cleaned and sanitized, has improved performance, and is easier to assemble. In one embodiment, the chocolate fountain includes a heating element encased in an aluminum enclosure. A basin containing chocolate is heated by contact with the aluminum enclosure. Because the aluminum enclosure has a relatively high thermal conductivity, the basin is heating substantially uniformly, thus reducing the occurrence of hot spots. Additionally, a plastic auger having a spiral flight rotates and lifts the melted chocolate upward to a top end of cylinder that houses the auger. The use of a plastic auger advantageously eliminates welding artifacts on the auger, such as burrs and pits, on which melted chocolate may accumulate. Accordingly, the plastic auger is easy to clean. A smaller chocolate fountain that may advantageously be more suitable for home use is also described herein.
