Abstract
An apparatus for dispensing a liquefied fluid including a housing, a main reservoir at least partially disposed within the housing, wherein the main reservoir is adapted to receive a substance, a heating element positioned to melt the substance into liquefied fluid, a second reservoir in fluid communication with the main reservoir, and a nozzle in fluid communication with the second reservoir, wherein the substance is dispensable from the nozzle as liquefied fluid.
Claims18
An apparatus for dispensing a liquefied fluid comprising:
- a housing;
- a main reservoir at least partially disposed within the housing, wherein the main reservoir is adapted to receive a substance comprising a food product;
- a heating element adapted to melt the substance into liquefied fluid, and heat the main reservoir to a temperature of at least 100° F., wherein the heating element comprises at least one of a wrapping coil, a fin, a plate, a film, a sheet, or a resistance heater,
- a second reservoir in fluid communication with the main reservoir;
- a nozzle in fluid communication with the second reservoir, wherein the substance is dispensable from the nozzle as liquefied fluid, wherein the main reservoir has a first volume, V1, wherein the second reservoir has a second volume, V2, and wherein the first volume is larger from the second volume;
- a logic element comprising a sensor adapted to selectively engage the heating element between an on and an off position;
- and
- a volume detecting element comprising a float adapted to detect a volume of liquefied fluid within the second reservoir and communicate said volume to the logic element.

An apparatus for dispensing a liquefied fluid comprising:
- a housing;
- a main reservoir adapted to receive a substance comprising a food product;
- a nozzle in fluid communication with the main reservoir, wherein the substance is dispensable from the nozzle as liquefied fluid;
- a pump adapted to generate a fluid flow of the liquefied fluid from the main reservoir to the nozzle;
- a heating element disposed within the housing such that the heating element is adjacent to the main reservoir, wherein the heating element is adapted to melt the substance into liquefied fluid, wherein the heating element comprises at least one of a wrapping coil, a fin, a plate, a film, a sheet, or a resistance heater, wherein the main reservoir defines an internal volume, and wherein the main reservoir further comprises:
- an outlet adapted to permit flow of liquefied fluid from the internal volume;
- and a filter disposed between the outlet and an inlet of the main reservoir, wherein the filter comprises a surface comprising at least one aperture comprising a feature adapted to disrupt surface tension of the liquefied fluid, wherein the feature comprises aperture sidewalls;
- a second reservoir in fluid communication with the main reservoir;
- a logic element comprising a sensor adapted to selectively engage the heating element between an on and an off position;
- and
- a volume detecting element comprising a float adapted to detect a volume of liquefied fluid within the second reservoir and communicate said volume to the logic element.
