Apparatuses, systems, and methods for brewing a desired portion of a beverage, such as a single-cup portion of coffee, are provided. The system can include one or more hopper assemblies configured to provide a controlled dose of beverage material to a brew chamber. The system can also include a water input system configured to wet the ground beverage material as the grinds enter the brew chamber and substantially prevent steam from reaching grinder components of the system. Further, the system can include an automatic cleaning mechanism such that a user does not need to manually clean components of a brewing machine between brew cycles.

A water control valve may comprise a valve shell, a sliding block, an operating valve piece, a fixing valve piece, a valve base and a check valve. The sliding block, the operating valve piece and the fixing valve piece are stacked sequentially and positioned inside the valve shell. The sliding block has a valve rod which is formed at an upper portion thereof and sticking out of the valve shell, and a bottom portion of the sliding block is engaged with the operating valve piece such that, through operating the valve rod, the sliding block is configured to drive and have movements with the operating valve piece concurrently to perform different aligning patterns between the operating valve piece and the fixing valve piece, thereby enabling the water control valve to control on/off operation of a faucet, the amount of water flow and the mixing ratio of hot/cold water.

The concepts relate to reducing energy loss associated with hot water systems. One example is manifest as a system with an automatic hot water recovery apparatus and selective hot water isolation devices. In one example a selective hot water isolation device is configured to be connected in fluid flowing relation with a first water line and a second water line and the selective hot water isolation device is configured to control water cross-over from the second water line into the first water line based upon water flow through the first water line.

A faucet assembly including a handle that rotates about a rotational axis extending perpendicular to an angled interface for adjusting a water parameter.

The invention relates to a control cartridge for single-lever mixer taps, comprising a housing in which a ceramic base disk and a rotatable and displaceable ceramic control disk resting on the base disk are situated. An inlet for the cold water and hot water, respectively, and an outlet for the mixed water are situated in the base disk, and the mixed water is diverted in the control disk and leaves the control cartridge via the outlet in the base disk. In order for automatic scalding protection to be integrated into the control cartridge, i.e., for the control cartridge to automatically close in the event of a scalding temperature of the mixed water, according to the invention at least one shape memory alloy (SMA) element is situated on the control disk, and takes on the temperature of the mixed water during operation of the control cartridge, and upon reaching a scalding temperature of the mixed water, expands and hereby automatically moves the control disk into the closed position in which no water arrives at the outlet, and the SMA element is supported on the one hand on the control disk and on the other hand on the housing.

A valve core connection structure of a valve assembly comprising: a body, two stop valve sets, two limitation structures, and two locking sleeves. The body includes a holder, a cold-water inflow connector, a hot-water inflow connector, a first outflow connector, a second outflow connector, a cold-water inflow seat, and a hot-water inflow seat. Each stop valve set includes a valve core, a limiting loop, a first fixing structure, and a second fixing structure. Each limitation structure is defined between a peripheral fence of each second accommodation cavity and the limiting loop so that the limiting loop is retained on the peripheral fence of each second accommodation cavity, thus limiting rotation of the limiting loop. Each locking sleeve is screwed on the cold-water inflow seat and the hot-water inflow seat so that the limiting loop and the valve core are limited in each second accommodation cavity.

A test cylinder of a valve assembly is mounted a body of the valve assembly, the body includes a holder containing an accommodation chamber, a bottom fence formed, and a cold-water inlet and a hot-water inlet which respectively communicate with a cold-water inflow pipe and a hot-water inflow pipe of the body. The accommodation chamber has a first mixing-water outlet and a second mixing-water outlet which individually communicate with a first outflow pipe and a second outflow pipe. The test cylinder includes a peripheral fence, a first orifice, an edge fence, and a first cavity defined. The peripheral fence has at least one second orifice, a second cavity, and an internal surround portion of the accommodation chamber. The edge fence has a closing portion extending from an outer wall thereof and has a conduit defined in the edge fence.

The present application provides a deck-mount thermostatic bathtub faucet, including: a thermostatic valve, installed on a deck and connected with a hot water inlet, a cold water inlet and a mixed water outlet, hot water from the hot water inlet and cold water from the cold water inlet mixed in the thermostatic valve to a certain temperature and flowing out of the mixed water outlet; and a diverter valve, installed on a deck and connected with the mixed water outlet, the diverter valve being provided with a first outlet pipe connecting with a faucet which is installed on a deck and a second outlet pipe connecting with a shower, the mixed water from the mixed water outlet into the diverter valve flowing into a faucet or a shower after being controlled by the diverter valve.

Apparatus is provided to electronically operate the hot water and/or cold water plumbing system of any home or business kitchen and bathroom with or without a faucet. The electronic water distribution center is a universal device that can connect to any faucet system. The apparatus, The users preferred faucet hot and cold manual controls will set the pressure for the water that is outputted from the spout. The said apparatus has a control system and a main system. The control system transmits a signal wired or wireless system temperature controller/(Android, Apple, Bluetooth, WIFI, ZIGBEE) to the main system to fluctuate one or more electronic solenoid water valve. One solenoid water valve controls the hot water and the second solenoid water valve control the cold water. Both solenoid used in unison creates a precise warm water temperature. The said apparatus can electronically control any home or business kitchen/bathroom, or any faucet electronically by the press of the hot, cold, or warm temperature switch push buttons or the controller systems on-board/external motion sensor.

A smart water heater system (SWHS) for a domestic water system having a plurality of fixtures has a water tank having a cold water inlet and a heat source configured to heat the cold water. The SWHS may also have a mixing valve to blend cold water with the hot water to produce blended water, wherein the blended water is directed to the domestic water system. The SWHS may have a controller in communication with the mixing valve configured to identify which fixture is being used when the domestic water system is drawing water from the water tank, determine an average water temperature utilized by each fixture, and adjust the mixing valve based on which fixture is identified such that a temperature of the blended water is generally equal to the average water temperature for the identified fixture.
