Gas venting system
View Patent ↗Beverage making equipment, water heating equipment, and methods for using such equipment which use heated water and dispenses heated water from a heated water reservoir. The apparatus includes a water line extending from the heated water reservoir to a dispensing point, the line having a positive slope between the reservoir and dispensing point. A vent tube may also be used communicating with and coupled to the line with a return passage communicating with the vent and reservoir. The method of dispensing water from a heated water reservoir involves dispensing water from the reservoir at one level and delivering water to a dispensing point at a second level positioned at a positive dimension above the dispensing port of the heated water reservoir. the method may also include providing a vent tube coupled to and communicating with the line for removing gas which evolves from water passing through the line and returning the gas to the reservoir.
1. A beverage making device comprising
a heated water reservoir for retaining a volume of water in a heated condition and a holder for retaining a beverage making substance for infusion with the heated water during a brewing process,
a dispensing line extending from a side of the heated water reservoir to a dispensing point proximate the holder for delivering heated water to the holder for making a beverage during the brewing process,
a vent tube having a first end communicating with and coupled to the dispense line at a position spaced from the reservoir,
a return passage communicating with a second end of the vent tube and the reservoir at a location on the reservoir spaced apart from the dispensing line for collecting gas from the dispensing line and returning it to the reservoir.
2. The beverage making device of claim 1 , further comprising the dispensing line having a positive slope between the reservoir and dispensing point.
3. The beverage making device of claim 1 , further comprising the vent tube having a cross sectional area which is greater than the cross sectional area of at least a portion of the dispensing line to facilitate out gassing and return of gas to the reservoir.
4. The beverage making device of claim 3 , further comprising a portion of the vent tube extending above the corresponding water level of the water in the reservoir.
5. The beverage making device of claim 1 , further comprising the return line extending from dispensing line and communicating with a top portion of the reservoir for coupling to the reservoir at a location above the water level of the reservoir.
6. A beverage making device comprising
a heated water reservoir for retaining a volume of water in a heated condition and a holder for retaining a beverage making substance for infusion with the heated water during a brewing process,
a dispensing line extending from a side of the heated water reservoir to a dispensing position proximate the holder for delivering heated water to the holder for making a beverage during the brewing process,
the dispensing line having a positive slope defined between the reservoir and the dispensing position,
a return line coupled to the dispensing line at one end spaced from the reservoir, and a second end of the return line coupled to the reservoir at a location on the reservoir spaced apart from the dispensing line for collecting gas from the dispensing line and returning it to the reservoir.
7. A method of dispensing water from a heated water reservoir of a beverage maker for use in making beverages, the method comprising the steps of:
providing a holder for retaining a beverage making substance;
providing a dispensing line communicating with the reservoir at a dispensing port and extending from the reservoir to a dispensing position proximate the holder for delivering heated water to the holder for making a beverage;
dispensing water from the reservoir at one level;
delivering water to a dispensing position at a second level positioned at a positive dimension above the dispensing port of the heated water reservoir;
providing a return line coupled to the dispensing line at one end and to the reservoir at a spaced apart end;
collecting gas from the dispensing line in the return line; and
returning the collected gas to the reservoir.
8. A method of dispensing water from a heated water reservoir of a beverage maker for use in making beverages, the method comprising the steps of:
providing a holder for retaining a beverage making substance;
providing a dispensing line communicating with the reservoir at a dispensing port and extending from the reservoir to a dispensing position proximate the holder for delivering heated water to the holder for making a beverage;
dispensing water from the reservoir at one level through the dispensing line;
delivering water to a dispensing position proximate the holder and at a second level positioned at a positive dimension above the dispensing port of the heated water reservoir;
providing a vent tube coupled to and communicating with the dispensing line;
removing gas which evolves from water passing through the dispensing line; and
returning the gas to the reservoir through the return line.
