Abstract
A combustion tube assembly of a water heater includes a combustion tube having an open end, a closed end, and an outflow opening between the open end and the closed end. A cavity of the combustion tube provides a chamber for a combustion of a water heater fuel, where the outflow opening provides an outlet for an exhaust gas resulting from the combustion of the water heater fuel to exit the combustion tube. The combustion tube assembly further includes a spring positioned in the cavity of the combustion tube at the closed end of the combustion tube.
Claims20
A combustion tube assembly of a water heater, the combustion tube assembly comprising:
- a combustion tube and having an open end, a closed end, and an outflow opening between the open end and the closed end, wherein a cavity of the combustion tube provides a chamber for combustion of a water heater fuel and wherein the outflow opening provides an outlet for an exhaust gas resulting from the combustion of the water heater fuel to exit the combustion tube;
- and
- a spring positioned in the cavity of the combustion tube and having a free end disposed between the open end and the closed end of the combustion tube, at least a portion of the exhaust gas flowing through an interior of the spring.
A heat exchanger assembly of a water heater, the heat exchanger assembly comprising:
- a combustion tube having an open end, a closed end, and an outflow opening between the open end and the closed end, wherein a cavity of the combustion tube provides a chamber for combustion of a water heater fuel;
- a spring positioned in the cavity of the combustion tube and having a free end disposed between the open end and the closed end of the combustion tube, at least a portion of exhaust gas resulting from the combustion of the water heater fuel lowing through an interior of the spring;
- and
- a hollow coil attached to the combustion tube, wherein the outflow opening provides an outlet for the exhaust gas to flow from the combustion tube into the hollow coil.
A water heater, comprising:
- a water tank;
- a combustion system positioned at a top end of the water heater;
- and
- a heat exchanger assembly positioned inside the water tank, the heat exchanger assembly comprising:
- a combustion tube having an open end, a closed end, and an outflow opening between the open end and the closed end, wherein a cavity of the combustion tube provides a chamber for combustion of a water heater fuel, wherein the open end is proximal to the top end of the water heater, and wherein the closed end is distal from the top end of the water heater;
- a spring positioned in the cavity of the combustion tube and having a free end disposed between the open end and the closed end of the combustion tube, at least a portion of exhaust gas resulting from the combustion of the water heater fuel flowing through an interior of the spring;
- and
- a hollow coil attached to the combustion tube wherein the outflow opening provides an outlet for the exhaust gas to flow from the combustion tube into the hollow coil.
