Description

Kitchen faucet with external control.

The invention relates to an electrically operated kitchen faucet wherein the faucet is activated via a control panel. In addition to tap water, the faucet is specially designed to pass through one outlet, such as filtered, with reverse osmosis, cooled or boiling water. The mains water comes via a hot water pipe and a cold water pipe and is controlled by temperature using manually operated faucets. To prevent specially treated water from being mixed with tap water, a drain is provided for the water that remains in the tap neck after the water supply has been shut off.

The neck is insulated internally so that the risk of burns is prevented.

The supply of specially treated water is controlled with electrically operated valves. The regulation is such that undesired mixing is prevented.

15 The kitchen faucet is furthermore provided with flow sensors and a safety valve.

The invention will be explained with reference to the drawing.

FIG. 1 shows the diagram of the tap.

The kitchen faucet (1) is mounted on the counter (2). Pipe (3) is the cold water supply. Piping (4) is the hot water supply. Pipe (5) is the supply of specially treated water. Pipe (6) is the discharge of water from the tap neck (7). At (8) the mixer is for cold tap water and at (9) the mixer is for hot tap water. At (10) there is a flow sensor for the cold water supply, at (11) there is a flow sensor for the hot water supply.

A normally open solenoid valve (13) is placed in the cold water supply, a normally open solenoid valve (14) in hot water supply, a normally closed solenoid valve (15) in the special inlet, normally closed solenoid valve (16) in the drain pipe. A normally closed safety valve (17) is placed between valve (15) and (16) and valve (1). The invention also relates to the possibility of using a plurality of supplies of specially treated water instead of a translation (15).

The control unit is indicated at (18) and the control panel at (19).

The control panel (19) contains the control keys (not shown) for mixed hot and cold, and special water.

The intention is that cold and hot tap water is conventionally controlled with manual control by means of mixer taps (8) and (9). After the mixer taps have been closed, after a signal from the flow sensors (10) and (11), the valve (16) of the discharge line (6) is opened for a set time so that the valve neck is drained. At the same time, the safety valve (17) is opened and the valves (13) and (14) are blocked.

When cold water and / or hot water are used, flow sensor (10) and flow sensor (11) are activated and the valves (15), (16) and (17) are blocked.

When using specially treated water, the supply valve (15) of line (5) is activated and the safety valve (17) is opened and valves (13), (14) and (16) are blocked. 5 Specially treated water then flows from supply line (5) via valve (15) and (17) and line (6) to tap neck (7).

After closing the supply valve (15), valve (16) and valve (17) are opened with a set time in order to empty the valve neck. The valves (13) and (14) are then blocked.

The cream sensors (10) and (11) block the water flow safety valve (17) to prevent undesired mixing and signal the end of a tap water flow to empty the tap neck through the valves (17) and (16) with a set time.

The control valves (8) and (9) can be combined into a mixer with one handle with which the outflow temperature can be controlled manually.

Instead of a single supply line for specially treated water (5), several supply lines with valves can be provided for several specially treated water flows.
