Disclosed is a system for treating fuel cell water discharged from a fuel cell using hydrogen as a fuel. The fuel cell water treatment system may include a fuel cell water storage device that receives and stores fuel cell water discharged from a fuel cell, a temperature adjustment device that adjusts a temperature of the fuel cell water stored in the fuel cell water storage device, and a washing device. In particular, when a preset condition is satisfied, and the washing device receives the fuel cell water from the fuel cell water storage device and discharges the fuel cell water through a faucet head of the washing device.

A hose includes a hose body provided with a first water passage, a connecting assembly connected to the hose body and provided with a second water passage communicating with the first water passage and a light transmitting portion, a temperature-sensitive light-emitting assembly mounted in the second water passage and a hydro-generator, a temperature sensor and an LED light, wherein the hydro-generator powers the temperature sensor and the LED light, the temperature sensor senses a water temperature, and the LED light emits light when the water temperature reaches a threshold, an impeller fixedly connected to a rotor of the hydro-generator and facing a water inlet direction, and a flow guiding base mounted in the second water passage and provided with a baffle, and the baffle is provided with a spiral-shaped water passing hole for water flowing through so as to drive the impeller to rotate.

Presented is a water saving system that includes an auxiliary tank, a diverter valve having an inlet port that operationally connects to a preexisting pipeline system to draw water restrained or flowing through the pipeline system, a first outlet port that operationally connects to the auxiliary tank using a pipe for storage of water, and a second outlet port that operationally connects to an ablutionary installation such as a shower head for showering. The system further includes a thermostat element disposed within the valve body, and a temperature adjuster rotatably configured in the valve body that enables a user to set a specific temperature based on which the diverter valve can switch the flow of water arriving from the preexisting pipeline system to either the first outlet port for storage in the auxiliary tank, or the second outlet port for showering via the shower head.

A plumbing fixture assembly including a fluid flow detection system for monitoring fluid flow and flow characteristics through plumbing fixtures without contacting the fluid. The fluid flow detection system communicates collected data related to the plumbing fixtures to a water management system, which analyzes the data and provides information to a user through a portal and user interface. The fluid flow detection system also tracks users of the plumbing fixtures for compliance with a hand washing routine. The hand washing compliance data is communicated to the water management system as well.

A water control system including a showerhead and a tub faucet. The faucet has a valve configured to automatically restrict fluid flow through the faucet and direct fluid to the showerhead as a function of a parameter, such as a predetermined water temperature. The faucet has many modes of operation, including a Reset Mode, an Auto-Divert Mode, a Bypass Mode, and a Cold Mode. A flow control device generates minimal back-pressure when in the Reset Mode such that water does not undesirably back flow to a shower head.

Systems and methods for facilitating water conservation and smart water control are provided. Water conservation and smart water control can be achieved using a smart water apparatus having the ability to approximate distance, mass, and/or specific characteristics of an object such as a human or inanimate object and adjust flow rate of water and/or temperature of the water based on the approximated distance, mass, and/or specific characteristics of an object. The smart water apparatus can be embodied, for example, in a network connected shower head or a network connected faucet.

An operating device includes a device main body, and an operating body operated by a user. The operating body is movable between a first position and a second position and enables activation of a water-related appliance by moving from the first position to the second position. The device main body includes a marker part that is different in outer surface color from a neighboring area of the device main body. When the operating body is placed at the first position, the operating body hides the marker part from the outside, and, when the operating body is placed at the second position, the operating body exposes at least part of the marker part to the outside.

Methods, systems, and devices are disclosed for implementing a water saving mechanism. In one aspect, a reservoir is provided to collect cold water while hot water is being heated. Once a desired temperature is reached, a valve is actuated to allow water to bypass the reservoir and be dispensed through a shower head. The reservoir can be used to dispense the cold water at a later time.

A method and apparatus for delivering water to a user at a control temperature by receiving cold water, receiving hot water and then adjusting a hot-side graduated-valve and a cold-side graduated-valve in order to adjust the temperature of mixed water according to an initial target temperature value. The temperature of the mixed water is sensed in order to provide feedback, which is necessary to adjust the hot-side graduated valve and the cold-side graduated valve. In some embodiments, hot-side graduated valve and the cold-site graduate-valve are also adjusted to achieve a target flow rate. A target temperature and a target flow rate is communicated to the apparatus by way of an air-gesture sensor.

The present invention provides an electronic plumbing fixture fitting including a demonstration feature.
