Heated air bath system

A bath system, comprising:

• a tub having a jet orifice;
• a fluid injection system fluidly coupled to the jet orifice, the fluid injection system comprising:
• a conduit having an inlet, an outlet, and a central opening between the inlet and the outlet;
• a heat source coupled to an outer portion of the conduit external to the central opening;
• an air supply source fluidly coupled to the conduit upstream from the inlet, the air supply source configured to provide a flow of air to the central opening;
• and
• a fluid injector fluidly coupled to the conduit upstream from the inlet and downstream from the air supply source, the fluid injector configured to provide an atomized spray of water to the flow of air to produce a combined flow of air and water;
• wherein the heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the central opening before the combined flow enters the tub through the jet orifice.

A fluid injection system for a bathtub, the fluid injection system comprising:

• a conduit having a central opening;
• a heat source coupled to an outer portion of the conduit external to the central opening;
• an air supply source fluidly coupled to the conduit, the air supply source configured to provide a flow of air to the central opening;
• and
• a fluid injector configured to provide an atomized spray of water to the flow of air to produce a combined flow of air and water;
• wherein the heat source and the conduit are cooperatively configured to heat the combined flow of air and water in the central opening before the combined flow enters a bathtub to produce bubbles.
