A spa tub includes a spa shell configured to contain a volume of water; a circulation system configured to create a flow of the water to and from the spa shell; and a testing system configured to acquire water samples from the volume of water and to perform water quality tests on the water samples. The testing system includes a housing; a circulation pump disposed within the housing configured to acquire the water samples from the volume of water; a replaceable reagent cartridge removably received within the housing; and a water test assembly disposed within the housing. The water test assembly is configured to receive the water samples acquired by the circulation pump and a reagent from the reagent cartridge. The water test assembly is configured to mix the water samples and the reagent and to perform the water quality tests on the mixed water samples and reagent.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment are provided. “Internet-of-Things” (IoT) functionality is provided for pool and spa equipment in a flexible and cost-effective manner. Network connectivity and remote monitoring/control of pool and spa equipment is provided by various components such as a network communication and local control subsystem installed in pool/spa equipment, and other components. Also disclosed are various control processes (“pool logic”) which can be embodied as software code installed in any of the various embodiments of the present disclosure.

A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.

A bathtub assembly includes a bathtub shell containing a volume of liquid, a circulation system in communication with the shell for creating a flow of liquid to and from the shell, and a dispenser assembly for introducing a substance into a portion of the flow of liquid into the bathtub shell. A control panel is rotatably mounted on an upper rim of the bathtub shell proximate to an inlet to the dispenser assembly and rotates to alternately cover or expose the inlet. A plurality of directed flow jets are connected to the bathtub shell for conveying the flow of liquid into the shell to create a directed flow of liquid within the bathtub shell.

A method for treating water in a spa or hot tub includes, for example, supporting one or more water treatment dispensers from a supporting structure in an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. A first dispenser includes a first water treatment material and the second dispenser includes a second different water treatment material. A supply of water is passed from the spa or hot tub into the skimmer and through the filter cartridge so that the first dispenser is disposed in the filtered water in the filter cartridge to dispense the first and/or the second water treatment materials from the first and/or dispensers, and a supply of treated filtered water from the filter cartridge to the spa or hot tub. One or more caps, for example, may be employed when the first and/or the second dispenser is not used.

The invention discloses a pool body, including: a pool inner wall including a side wall and a bottom wall which are connected, the side wall and the bottom wall of the pool inner wall forming a water holding cavity for storing a fluid; an additional chamber arranged on the pool inner wall; and an additional pipeline built into the additional chamber. The invention can save the space in the pool.

A bathtub (1) which comprises: a main body (2) having side walls (22, 22a, 22b), at least one of which presents an inner surface provided with guide means (3); supporting means (4) engaged with guide means (3) and configured for supporting at least a portion of user's body in order to allow, in use, simulating user flotation.

An induction heating system for a basin of a pedicure chair and a pedicure chair with one or more pumps and one or more heating sources are disclosed. A conducting object is located on an interior side of a first wall of the basin, with an induction heater located on the exterior side of the first wall. The conducting object is separated from the induction heater by a solid portion of the first wall. The induction heater is configured to generate a high frequency field that passes through the solid portion of the first wall and causes the conducting object to generate heat. A controller is configured to turn on/off the induction heater to maintain a desired temperature in the basin.

An agent analysis system includes a terminal product system, a remote diagnosis system (RDS), and an agent analyzer. The terminal product system is supplied with a power source and provided with a current sensor to sense the power source. The RDS is used to transmit at least one control instruction via internet for the terminal product system. They agent analyzer is used to communicate with the terminal product system and the RDS, and configured to measure and analyze the electricity use characteristics of the terminal product system to be transmitted to the RDS; and receive and convert the control instruction from the RDS via internet for the terminal product system.

A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.
