Abstract: A device for controlling a water heater comprises a touch interface containing five water temperature modes; a capacitive touch unit including a touch sensing circuit, wherein the capacitive touch unit is configured to the touch interface for sensing user touch; a controller connected to the capacitive touch unit, wherein the controller is configured to switch at once among five water temperature modes according to preset sequence when touch interface senses user touch and sends touch signal; wherein one of five-water temperature modes comprises a water temperature without heating function each of remaining four water temperature modes corresponds to temperature range, and temperature range of two adjacent water temperature modes has certain overlaps.

Abstract: A faucet assembly comprises: a water supply pipeline comprising a water outlet pipeline section and a water inlet pipeline section connected to each other, wherein the water inlet pipeline section contains a throat section with smaller cross sectional diameter; a shell made of hard materials and wrapped around the throat section, so as to define a closed space that contains air around the throat section, while the throat section has an opening to the closed space; a flexible membrane wrapping layer made of elastic materials and is hermetically sealed on the inner side of the shell, so that the closed space that contains air has an elastic, retractable and sealed boundary; a heater connected in series to the inlet pipeline section and is positioned in the upstream of the shell along the water outlet direction, to heat the water that is about to flow into the throat section.

Abstract: The invention discloses a control device for faucet assemblies. Faucet assemblies comprises a faucet spout with a first and a second water outlet; a first water supply pipe communicating with second water outlet, a second water supply pipe communicating with first water outlet and containing a water outlet pipe section connected with first water outlet and a first water inlet pipe section and a second inlet pipe section communicating with water outlet pipe section, control device comprising a first and a second solenoid valve respectively provided on first and second water inlet pipe section; a capacitive touching unit disposed on faucet spout; and electrically connected to a second control unit, when touch time is less than first predetermined time, opening second solenoid valve, and is greater than second predetemined time, opening first solenoid valve. The invention has effects of meeting different demands, combining touch and manual, and being convenient operation.

Abstract: A control device of water heater comprises a touch pattern position for selecting water temperature stall formed on water heater; a capacitive touch unit including a touch sensing circuit provided in water heater and corresponding to touch pattern position for selecting water temperature stall, being used for sensing touch action of human body and sending touch signal, a control unit connected to capacitive touch unit, touch pattern position for selecting water temperature stall sending touch signal when touch action is sensed, and control unit switching between preset five stalls. Wherein one of five stalls is a neutral stall doing, and the remaining four stalls are preset water temperature stalls. Each stall corresponds to a temperature range, and two adjacent stall have coincident range.
