A mixing valve assembly is disclosed. The mixing valve assembly can include a cold water connector, a hot water connector, an electronic valve system, and a tube. The cold water connector can have a through-hole configured to slideably receive at least a portion of a first tubular portion of a cold water inlet, and the hot water connector can have a through-hole configured to slideably receive at least a portion of a second tubular portion of a hot water outlet. The electronic valve system can be configured to transition a valve between an open configuration and a closed configuration such that cold water can be selectively permitted to flow from the cold water connector to the hot water connector. The mixing valve assembly can be configured to selectively permit cold water to bypass the tank of water heater.

Introduced are methods and systems for an adjustable bed device configured to: gather biological signals associated with multiple users, such as heart rate, breathing rate, or temperature; analyze the gathered human biological signals; and heat or cool a bed based on the analysis.

The present invention provides an electronic plumbing fixture fitting including a learning system and a reference system. The electronic plumbing fixture fitting includes a user input module and a processor. The user input module includes a mechanism to receive from the user numerical value(s) of parameter(s) for water to be delivered through a discharge outlet of the electronic plumbing fixture fitting (e.g., a temperature) and a mechanism to deliver to the user the numerical value(s) of the parameter(s) via the water delivered through the discharge outlet of the electronic plumbing fixture fitting. Additionally, the processor includes a mechanism to learn a range of the numerical value(s) of the parameter(s) from a minimum value of the parameter to a maximum value of the parameter (e.g., from a lowest achievable temperature to a highest achievable temperature).

The instrumented device comprises a body to be attached to a mixing valve producing a mixed fluid by blending hot and cold fluids. The body defines a main channel and a bypass channel, provided for the outflow of the mixed fluid through the body. The device comprises a turbine arranged in the main channel, being bypassed by the bypass channel, such that, as soon as the flow rate of the mixed fluid flowing through the body is non-zero, all or a portion of the mixed fluid flowing through the body passes through the main channel passing through the turbine and, at the same time, a portion of the mixed fluid flowing through the body is likely to bypass the turbine by flowing in the bypass channel between the upstream and the downstream of the turbine.

A pot filler including a metered dispense input device for dispensing of predetermined volumes of water. The pot filler illustratively includes an electrically operable valve operably coupled to a metered dispense input unit, and a control module configured to control operation of the electrically operable valve.

Two problems with existing electronically controlled mixing valves for domestic use is their size and difficulty accessing and repairing them. Their size means that they often become hidden behind wall linings, and because of the way in which they are plumbed into the pipework of a house, they are difficult to access and remove for repair or replacement. Disclosed is a compact and replaceable mixing valve cartridge that can be mated to a fixed fitting that is permanently plumbed into the pipework of a house. The compact size allows the cartridge to be positioned behind the type of removable face plates that are often installed over existing manually operated mixing valves. Simplified valve actuators and a compact mixing and temperature sensing configuration have facilitated the compact size. The valve cartridge can simply be accessed, unbolted and removed, without the need for extensive plumbing re-work.

A temperature control system includes: first adjusting the temperature of fluid in a first portion the fluid having a first temperature determined based on a second temperature higher than the first temperature or the second temperature; second adjusting the temperature of the fluid supplied to a target at a second portion between the first portion and the target; first detecting the temperature of first fluid supplied from the first to second portion; second detecting the temperature of the fluid or the target at a predetermined position between an outlet of the second portion and an inlet of the first portion; controlling the first adjusting based on the first detected value such that the temperature of the first fluid becomes a first temperature; and controlling the second adjusting based on a the second detected such that the temperature of the fluid becomes a second temperature at the predetermined position.

A water temperature controller for a shower that comprises a quiet and efficient, thermostat controlled, motorized device that reliably monitors and maintains water temperature of a shower at a level set by a user for use in single valve or double valve shower systems.

A temperature control apparatus is provided, which is capable of, even when it is necessary to perform control by means of valves in a plurality of channels, promptly controlling a temperature of an area to be temperature-controlled promptly to a desired temperature, while avoiding complication and enlargement of the apparatus as a whole. Passage and blockage of a heating medium passing through a first supply channel to a mixing channel, a temperature of the heating medium being controlled by a first temperature regulating unit at a predetermined temperature, and passage and blockage of a heating medium passing through a second supply channel to the mixing channel, a temperature of the heating medium being controlled by a second temperature regulating unit, are controlled by a valve unit. The valve unit includes a first spool valve and a second spool valve, which are coupled through a heat insulating layer.

Disclosed herein relates to a field of an intelligent shower system, and more particularly, to an intelligent shower system used for a shower and/or outputting water for other purposes, and methods of providing a recipe, and automatically updating the recipe associated with the intelligent shower system. In some embodiments, a method of updating a recipe is provided, in which the method includes: a set-point reception step of receiving, by a remote computing device, history data including one or more set-points which are inputted to a shower device directly or indirectly from a user; and a recipe updating step of generating, by the remote computing device, an updated shower recipe by applying the history data to a previous shower recipe.
