Systems, apparatus and methods for providing air and water to hot tub jets. The present teachings include jet assemblies, manifold assemblies, and related components, as well as methods of assembling hot tubs involving these components. In some cases, the present teachings describe the use of dual extrusion tubing to route air and water through adjacent, connected fluid conduits. In some cases, the present teachings describe a press-and-click method of connecting various components.

A whirlpool bath with descaling function is provided. The whirlpool bath 1 comprises a bathtub body 10 including a bathtub 11, suction port 20 sucking the water contained in the bathtub 11, first jet nozzles 30 jetting bubble water into the bathtub 11, a circulation pipe 40 including a water supply pipe 41 and a return pipe 42, a pump 50 installed in the circulation pipe 40, a bypass pipe 60 branched from the water supply pipe 41 and connected to the return pipe 42 to directly return the water in the water supply pipe 41 to the pump, and a second jet nozzle 70 mixing air with water passing through the bypass pipe 60 to generate and jet bubble water. The scale of the circulation pipe 40, the pump 50 and the bypass pipe 60 is removed by bubble water generated by the second jet nozzle 70.

An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

A portable, personal therapy chamber for provision of infrared radiation therapy. The therapy chamber includes a pair of telescopically positionable cabins that are lightweight and easily portable by a single user. The therapy chamber is configured for use by a single person lying generally prone on a surface. The cabins are disposed to overlie the user and include a plurality of infrared radiation elements that direct infrared energy toward the user's body. When using the therapy chamber, the user's head extends from an open end of the cabin. A facial treatment fixture is integrated with the cabin to be extendable longitudinally from a terminal end thereof and to overlie the user's face/head. The therapy chamber can be configured to provide mild hyperbaric oxygen therapy in addition to infrared therapy.
