Description

The present invention relates to a shower mixer with a fitting body, a Zuflussreguliereinrichtung, an extendable hand shower and one of the Zuflussreguliereinrichtung through the fitting body leading to the hand shower flexible hose line.

Faucets with pull-out spray are often used as kitchen faucets. The pull-out spray is connected via a flexible hose, which is guided through the fitting body, to a mixer tap of the fitting. The mixer tap is often designed as a single-hand mixer. In addition, the jet spray of the water jet can often be switched over to the pull-out spray, for example between a ventilated jet and a shower spray.

In existing fittings with pull-out spray, the operation is often cumbersome or unergonomic. Thus, with one-handed operation, the water jet must first be set and tempered before the hand shower can be pulled out while the jet of water is running. In addition, conventional showers usually have to be pulled down from the outlet pipe or pushed back from below. Especially when pulling out the hand shower is easily splashed water uncontrolled.

Although there are also known hand showers with integrated shut-off valve. Here, however, it is again cumbersome to control the temperature of the water jet, since the mixed water temperature can be adjusted only when the water jet is running. The switching between different types of jet is often cumbersome or unergonomically solved in known pull-out spray, which can lead to uncontrolled splashing of water just when switching to a sharper shower jet.

The present invention has for its object to provide a mixer with pull-out spray, which can be easily operated.

The object is solved by the features of claim 1. Advantageous embodiments are given in the dependent claims.

In a shower mixer of the type mentioned, the object is achieved in that the hand shower is formed as a downwardly facing handle, the handle having a downwardly open handle end, which forms the water outlet of the hand shower, and wherein the hand shower a mechanical switch, preferably Tast switch, for switching between at least two different spray modes, which is arranged on the side facing the fitting body side of the handle.

The newly shaped hand shower results in a particularly ergonomic operation. The hand shower is here in the form of a "pistol grip" shaped and can be grasped with one hand and pulled out to the front. The hose line of the hand shower or a connection piece connected to the hose line can in this case be oriented in the manner of a "gun barrel" at the upper end of the handle at right angles by the user. In this way, the handle can be very easily grasped and the hand shower can be pulled out in an approximately horizontal movement forward from the fitting body or fitting housing. The downwardly open handle end here in this case constantly down and can be such. be guided in a circular motion on the dishes.

In addition, it is provided in the context of the present invention that the hand shower has a mechanical switch, preferably key switch, for switching between at least two different spray types. If the hand shower is shaped in the manner described above in the manner of a handle, the switch can preferably be arranged on the side facing the fitting body side of the handle. The operation of the beam switching can thus by the index or middle finger of the gripping hand done, so that there is a completely new type of operation of the hand shower.

The outlet pipe of the fitting, in which the handle-shaped hand shower is inserted, may in this case extend approximately horizontally in its end region or enclose with the horizontal an angle between -5 ° and + 30 °, ie slightly (<5 °) inclined downwards or slightly ( max 30 °) upwards. Closing the handle of the hand shower and a forward facing connector on the hand shower for the hose end of the hose an approximately right angle, this means that the handle formed by the handle end of the hand shower approximately vertically down to slightly forward inclined (up to 30 °) runs. In the context of the present invention, provision is made in particular for the angle between the handle and the connection piece of the hand shower to be in the angular range of 90 ° plus / minus 15 °, preferably plus / minus 10 °, more preferably plus / minus maximum 5 °.

Preferably, the Zuflussreguliereinrichtung comprises one or more electrically operated Stetigventile for regulating a flow rate and / or mixing temperature of a water flow and a control device for controlling the continuous valves. On the hand shower, a manually operable electrical control signal transmitter is arranged, which is signal technically connected to the control unit, wherein the control unit is adapted to control the continuous valves in response to the control signal transmitter coming control signals to adjust the flow rate and / or mixing temperature of the water flow. The serving for actuating the valve knob can be arranged in a particularly ergonomic manner in the upper region of the handle on the hose connection opposite the handle side preferably at an angle with respect to the handle axis. This type of arrangement allows easy operation with the thumb of the gripping hand.

Conveniently, the valve is designed as an electronically controlled valve and can be operated via the arranged on the hand shower control signal generator. The operation can in this case in particular an opening and Close the valve or include a setting of the mixing temperature. In this way, the faucet can be operated with the hand shower pulled out with one hand.

The control signal generator is preferably connected to the control unit via an electrical control line extending in or on the hose line. In this way, the control line is protected by the flexible hose when pulling or pushing the hand shower against damage. Alternatively, a short-range radio link for signal transmission between the control signal generator and the control unit would also be conceivable, for example a Bluetooth connection.

In the context of the present invention, it is provided in particular that the control signal generator has a rotary control which, when actuated, generates a first control signal which depends on a relative or absolute angle of rotation of the rotary control. The rotary control and therefore the first control signal can serve in this case in particular for regulating the mixing temperature. On the one hand, it is conceivable that the mixed water temperature corresponds to the absolute value of the angle of rotation, that is to say the position of the rotary control. The knob can thus be brought into a certain rotational position or left in this and the controller controls the mixing water temperature electronically after the opening of the valve to a correlating with the position of the rotary mixing temperature. The rotary control can in this case in particular have an end stop, which corresponds to the maximum temperature.

Alternatively, however, it is also possible for the control unit when opening the fitting initially to regulate a preset or last set temperature value and a relative rotation angle change leads to a corresponding increase or decrease of the setpoint temperature. In this case, the rotary knob is preferably designed without end stop, so endlessly rotatable. In this case, for example, an incremental rotary encoder or a magnetic pulse encoder can be used as a rotary controller.

In the context of the present invention, it is also preferably provided that the control signal generator additionally has a pushbutton function which generates a second control signal when actuated. This second control signal can be used, in particular, to control the inflow regulating device by means of the control device in such a way that it releases or shuts off a water flow. Thus, with the same hand with which the hand shower is grasped, the water flow can be adjusted by simply pressing the control signal generator, preferably the rotary control, and the mixing water temperature can be set by turning the control dial. Particularly ergonomically, the rotary control can be configured in that it is in the form of a flat turntable, preferably in the upper region of the extendable hand shower, is formed.

Such a rotary control equipped with push-button function also allows a third type of operation, namely a simultaneous pressing and turning. This third type of operation can preferably be detected by the control unit and used to change the flow rate of the water jet in dependence on the rotation angle of the rotary knob. For this purpose, either a simultaneous receipt of a first and a second control signal can be determined on the control unit, or the control signal generator can be configured such that it generates a third control signal upon actuation of the rotary control and simultaneous actuation of the push-button function, which can be detected by the control unit.

In a preferred embodiment of the present invention may be integrated into the control signal generator, a display device which is connected by signal technology with the control unit and generates a visual display that depends on the set flow rate and / or mixing temperature of the water flow. In particular, in the present invention, light rings are provided in different signal colors, with which the water temperature can be displayed. For example, a blue light ring for cold water, an orange light ring for hot water and a red light ring for hot water. In other words, by means of the light colors or their Color temperature the selected or set water temperature are displayed.

Finally, it is also provided in the context of the present invention that the hand shower has a removable jet bottom or jet regulator, which engages in an outlet opening of the hand shower and can be solved by a release button of the hand shower. This allows easy cleaning and decalcification of the jet bottom important for the beam properties.

In another preferred embodiment, the control signal transmitter comprises a rotary knob which has a haptic perceptible during rotary actuation. The user receives thereby a haptic feedback of the turning length and the screening thus enables a more precise adjustment while turning.

In a further preferred embodiment, the hand shower has a switched on a push button diverter, which adjusts a waterway within the hand shower between two water outlet areas for different types of steel. Here, the diverter can be designed so that it remains in operation by the water pressure in the switched position (shower jet) and automatically returns to the normal position when switching off the water flow. Alternatively, at least one return spring can also be provided, which automatically returns the diverter to an initial position when the changeover key is released. In this case, it is possible to repeatedly switch back and forth between two spray modes during use, without the water flow having to be switched off for resetting the diverter.

FIG. 7

in an isometric view of an embodiment of a shower mixer with a single-lever mixer instead of electrically operated valves.

In FIG. 1 a kitchen faucet 1 is shown with pull-out spray 2. The pull-out spray 2 is also referred to below as a hand shower. The kitchen fitting 1 has a fitting body or fitting housing 3, in the front, open end of the pull-out spray 2 is inserted. The pullout spray 2 has the shape of a downwardly open handle and is angled at its upper end approximately at right angles to the front. The angled forwardly portion of the hand shower 2 is designed as an insertion and inserted in the fitting body 3. On its side facing away from the fitting body 3 is in the upper part of the hand shower 2, a thumb wheel 4 is arranged, which serves to operate the valve 1. On the side facing away from a user or the fitting body 3 side facing the handle-shaped hand shower 2 carries a rubber coating 5, which serves as a gripping aid for better gripping the hand shower 2. The downward facing open side of the hand shower 2 is through completed a beam bottom 6 with integrated jet regulator for different spray types.

FIG. 2 shows the hand shower 2 in a side view. In the rubberized grip region 5, a changeover key 7 is arranged, which serves for the mechanical switching between different jet types, namely from a ventilated jet to a spray jet. The angled, forward facing portion of the hand shower 2 tapers step-like and finally flows into a flexible hose 9. The tapered portion 10 is an insertion for inserting the hand shower in the corresponding receiving opening of the fitting body 3. A nose 11 in the tapering region of the insertion 10th serves as a rotation of the hand shower 2 and corresponds with a corresponding recess on the receiving opening of the fitting body. 3

FIG. 3 shows a view of the hand shower 2 from below. Two different beam areas can be seen here in the radiant floor 6, namely an inner area 6a for a ventilated jet and an outer area 6b annularly surrounding the inner area 6a with individual openings for a fanned out spray jet. By means of the key 7 can be switched between these two types of beam. Integrated in the beam bottom is a corresponding jet regulator for the inner beam region 6a. The jet bottom 6 is latched to the underside of the handle-shaped hand shower 2 and can be unlocked for cleaning over a concealed release button and removed for cleaning.

A longitudinal section through the hand shower 2 is in FIG. 4 shown. In the upper area on the side facing a user, the rotary control 4 is arranged at an angle of about 45 ° as a control element with which the kitchen faucet can be operated. The rotary control 4 acts as an electrical control signal generator and on the one hand enables actuation by rotation on the control crown 4a of the operating element. On the other hand, the rotary control 4 allows an operation by pressing the rotary control 4 by an integrated push-button function.

In addition, the rotary control 4 used in the exemplary embodiment is finely screened, so that the user receives a haptic feedback of the turning length and the precision of the rotation. The control dial can be turned 360 ° without impact.

The control element 4 also has on its upper side a light ring 4b, which can be controlled in different luminous colors or color temperatures to display a user a set water temperature. Operating element or control signal generator 4 is thus designed, on the one hand, to generate a first control signal dependent on a relative or absolute angle of rotation of the control crown 4a or, upon pressure actuation, a second control signal. As a third type of operation, the operating element 4 allows a simultaneous rotation and pressing. In addition, it can be distinguished between a long and short operation of the push-button function as well as between a two or more consecutive short presses of the push-button function in the manner of a "double click".

Behind the control crown 4a of the control element is the actual electrical signal generator 4c, which is inserted into the hand shower 2 and from which leads a (single or multi-core) electrical signal line 4d to an electronic control unit of the valve. The signal line 4d is perpendicular to the plane offset the passing through the hand shower 2 waterway over.

The control signal generator 4 generates electrical control signals via the in FIG. 5 schematically shown signal line or control line 14 are transmitted to a control unit 17 of the kitchen fitting 1. The electrical control signals can be transmitted either as digital or as analog or as mixed partly analog and partly digital signals. In this case, the control line 14 can be embodied in any desired manner as single or multi-core as separate line or shared with other modules or as a data bus.

The changeover button 7 acts on pressure actuation mechanically to a switching device 12, which serves to switch between different spray types and to direct the flow of water through the hand shower 2 either to the inner region 6a or to the annular outer region 6b of the beam. For this purpose, a laterally movable diverter 7a is provided, which is actuated by the Umsetzaste 7 and adjusts the waterway within the hand shower 2. In the unactuated position, the diverter 7a directs the flow of water to the central region, which opens into the jet regulator 6a. In pressed key position of the changeover key 7, the diverter 7a directs the flow of water to the outer region 6b with individual openings for a fanned out shower jet.

In known shower faucets with reduced pressure, the manual shower conversion is usually designed such that the jet remains switched on until the water flow is turned off. In contrast, the changeover function is implemented in the exemplary embodiment such that the diverter 7a switches back to the first jet mode when the changeover key is released. This can be permanently switched back and forth between the two types of spray during use. This is made possible by the integration of one or more return springs 7b, which reset the diverter 7a when the changeover key 7 is released.

For an ergonomic and intuitive operation contributes in the context of the present invention in addition to the provided on the hand shower 2 control 4 and the handle-shaped design of the hand shower 2, the arrangement of the changeover 7 in the grip area 5 on the dashboard body 3 facing side of the hand shower 2. The hand shower 2 can be gripped with the operating hand while the Umsetzaste 7 are operated with index or middle finger. At the same time can be operated with the thumb of the actuating hand of the control signal generator 4 to regulate the flow of water exiting the lower end of the hand shower.

Both the control element 4 and its arrangement in the upper region of the hand shower 2 and the arrangement of the Umsetzaste 7 on the side facing away from the user side of the hand shower 2 allow a completely new, ergonomic operation of the hand shower 2 and can be used individually or in combination with faucets Pull-out spray is used.

For unlocking and releasing the jet bottom 6, a hidden release button (not shown) may be provided, which is arranged so that it can not be pressed in normal gripping the hand shower 2. With the help of a suitable thin object or the fingernail, the concealed release button can be pressed to remove the beam bottom for cleaning.

In the in FIG. 5 shown side view of the fitting 1, in addition to the course of the flexible hose 9 and the along the hose line extending electrical control line 14 is shown. The hose 9 extends from the hand shower 2 through the fitting body 3 and from there below a kitchen sink or kitchen countertop on which the fitting 1 is installed, in a free loop, optionally with falling weight (not shown), to a mixer tap 17, with the Amount of water and mixing temperature can be adjusted. The mixer 17 thus serves as Zuflussreguliereinrichtung. It has two external connections 15, 16 for hot and cold water. Electrically controllable continuous valves 18, 19 serve to regulate the inflow-side cold water or hot water and output as mixed water for connection of the hose 9. The electrical control line 14 leads to the control unit 20, which evaluates the electrical control signals of the control element or control signal generator 4 and the proportional valves 18, 19 controls accordingly to output a set by the user mixed water temperature. At the mixed water connection of the mixer tap 17, a temperature sensor (not shown) may additionally be provided, with which the control unit 20 monitors and controls the mixed water temperature.

The control line 14 is preferably fixedly connected to the flexible hose 9. It may, for example, in the form of a stranded wire or a foil conductor glued to the outside of the tubing 9 and / or fixed by means of an around the hose 9 outer shell, such as a fabric wound or a metallic winding tube. The hose 14 may also be integrated into the hose wall of the hose 9 or extend within the hose 9.

The continuous valves 18, 19 of the electrically controllable mixer 17 are shown here merely by way of example and schematically. Instead of separate continuous valves for hot and cold water supply and a common continuous valve, which acts on both tributaries simultaneously, can be used, similar to that is achieved in a mixer tap of known design by a common control disk. In addition, if appropriate, a shut-off valve for releasing or shutting off a water flow can be provided. However, the latter function can also be taken over by the continuous valves 18, 19. Essential within the scope of the present invention is merely that the amount of water and / or mixing temperature are electronically controlled.

The mixer 17 may be in the in FIG. 5 shown as a separate assembly below a sink or kitchen worktop on which the kitchen fitting 1 is mounted to be installed. Equally, however, it is also possible to integrate the mixer tap 17 in the fitting body 3 of the kitchen faucet.

• Bei einmaligem Tippen auf das Bedienelement 4 wird durch Öffnen des entsprechenden Ventils lediglich kaltes Wasser ausgegeben. Der Leuchtring 4b wird so angesteuert, dass er blau leuchtet.
• Bei zweimaligen Tippen werden beide Stetigventile 18, 19 soweit geöffnet, dass warmes Wasser einer vorgegebenen bzw. vorgebbaren Mischtemperatur ausgegeben wird. Der Leuchtring 4b leuchtet orange.
• Durch dreimaliges Tippen wird heißes Wasser ausgegeben, der Leuchtring leuchtet in Warnfarbe Rot.
• Durch Drehen der Steuerkrone 4a wird die Mischtemperatur geändert. Die Leuchtfarbe bzw. Farbtemperatur des Leuchtrings 4b wird entsprechend der gewählten bzw. eingestellten Wassertemperatur verändert.
• Ein gleichzeitiges Drehen und Drücken bewirkt eine Änderung der Durchflussmenge.

The control unit 20 has a microprocessor (not shown), with the aid of which the function of the control unit is programmable. In the exemplary embodiment, the control unit is programmed such that it performs the following functions:

• With a single tap on the control element 4 is released by opening the corresponding valve only cold water. The light ring 4b is controlled so that it shines blue.
• When tapping twice both proportional valves 18, 19 are opened so far that hot water of a predetermined or predetermined mixing temperature is output. The light ring 4b lights orange.
• By tapping three times hot water is emitted, the light ring lights up in red warning color.
• By turning the control crown 4a, the mixing temperature is changed. The luminous color or color temperature of the luminous ring 4b is changed according to the selected or set water temperature.
• Simultaneous turning and pressing causes a change in the flow rate.

In addition, various special functions can be implemented: By prolonged pressing the current mixing temperature as a new preset for the currently active operating mode, so output of cold, warm or hot water, stored. This is indicated by a violet glow of the light ring 4b. Thus, in the exemplary embodiment, three different preset temperatures for the operating modes cold, warm and hot can be stored. In addition, a prolonged press activates a cleaning mode and / or a thermal disinfection. The light ring 4b lights up either green (cleaning mode) or red (thermal disinfection). By pressing and holding the control element during a running action, it can be aborted.

The selection or actuation is done in the embodiment by pressing on the control crown 4a. Alternatively, however, a selection could also be made on the control crown of the rotary control. For example, additional functions might not be limited to long, e.g. 3-second pressing, but alternatively be selected by pulling on the control crown.

The programming of the control unit 20 or operation of the control signal generator 4 is merely exemplary here and can be changed in the context of the present invention in any desired manner. In addition, other functions / programs can be integrated, such as a child barrier, a dementia function or a filling function that outputs a predetermined or predefinable amount of water and then closes the valve automatically. For example, different quantities can be specified for pot filling or for rinsing.

Furthermore, the fitting can also be connected to a local computer network. In this way, monitoring, monitoring, service analyzes, updates, remote control or even settings can be made conveniently via a computer or a tablet PC.

In particular, an incremental rotary encoder or rotary encoder can be used as a rotary controller of the integrated control signal generator 4, with which angle changes and direction of rotation can be detected incrementally. Such an incremental rotary encoder can operate, for example, on the principle of magnetic scanning, in which the rotational movement of a permanent magnet or hard magnetic carrier is read out with inscribed in the form of a magnetization division by magnetic sensors such as Hall elements or magnetoresistive sensors. Such non-contact magnetic scanning allows a long-lasting, trouble-free and wear-free operation of the control signal generator. The push-button function can be realized, for example, by means of an integrated microswitch, which is actuated when the rotary control 3 or only its central area is pressed in.

At another, in FIG. 6 shown embodiment, an operating element 4 'with a total of 5 buttons in the form of a membrane keyboard is provided on the hand shower. When pressed, a slight resistance and / or a pressure point are noticeable. The individual symbols are backlit. By a color gradient from blue to red, the setpoint temperature can be displayed. By tapping or permanently pressing the individual buttons, the quantity and temperature are changed. On the side facing the armature of the hand shower 2 is located as in the previous embodiment, a key switch for switching between different types of jet, but in the view of FIG. 6 is covered.

The operation can be done as follows. The middle button has the symbols "On- / Off". Four more buttons are arranged around the middle, one left, one right, one top and one bottom of the "On / Off" button. The right and the bottom buttons carry a symbol "-", the top and the left a symbol "+". With each of these buttons the valve can be started. The valve is switched off with the symbol "On- / Off". When the valve is switched on, the on / off symbol should indicate the setpoint temperature of the water based on a color gradient from blue to red. In standby mode, this symbol will light up white.

When the valve is switched off and the "-" symbol is pressed once, a preset, freely programmable chilled water quantity and temperature is started (Direct Access 1)

When the valve is switched off and the "On / Off" symbol is pressed once, a preset, freely programmable mixing water quantity and temperature is started (Direct Access 2).

When the valve is switched off and the "-" symbol is pressed once, a preset, freely programmable hot water quantity and temperature is started (Direct Access 3). The programmable hot water temperature should not exceed 40 ° C.

The symbols "+" (left) and "-" (right) regulate the water temperature. If the hot or cold water symbol is briefly pressed (t <1s) when the valve is switched on, a gradual increase or decrease in temperature of 1/20 of the complete route should take place. When exceeding 40 ° C a noticeable signal of the operation must be made (eg blinking or vibration element) and the further increase of the temperature takes place in smaller steps (eg 1/40 of the complete distance). If the upper or lower temperature limit is reached, the "On / Off" symbol should flash red or blue.

If the hot or cold water symbol is pressed permanently (t> 1s), the temperature steps mentioned above are barely noticeable and the temperature should be increased / decreased linearly. Where the duration of pure cold water to only hot water max. t = 4s should be .. When exceeding 40 ° C must be a noticeable signal of operation (for example, flashing / vibration element). A white increase in temperature is only possible by releasing the "-" symbol and pressing again or pressing and holding. The further increase of the temperature takes place in smaller steps (1/40 of the complete distance). If the upper or lower temperature limit is reached, the "On / Off" symbol should flash red or blue.

The symbols "+" (top) and "-" (bottom) regulate the amount of water. These two symbols are backlit white when the fitting is switched on. If one of the water quantity control symbols is pressed briefly (t <1s), a gradual increase in volume, resp. Reduction of 1/20 of the entire route take place. If one of the water quantity control symbols is pressed permanently (t> 1s), the quantity steps mentioned above are hardly noticeable. The duration from maximum flow to minimum flow (no water) max. t = 4s should be.

If the "On- / Off" symbol is pressed for a long time (t = 4s), an optional, electronically actuated drain valve can also be closed or reopened when it is held again. The symbol "On- / Off" flashes green 3 times.

By keeping the symbols (t> 8s) "On- / Off", "-" and "-" for a long time, the water quantity and temperature pre-stored on these keys (Direct Access) can be overwritten with the current value. The symbol "On- / Off" flashes 3 times violet.

At another, in FIG. 7 shown embodiment, a control signal generator is omitted or at least only optional (dashed lines). In this case, the valve is not designed as an electrically controlled valve with electrically actuated continuous valves, but can also, as in FIG. 7 shown, be equipped as a conventional mixer tap with a single-lever mixer 22. In the interior of the fitting body is in this embodiment, a cartridge with ceramic valve discs per se known design. The valve discs can be adjusted by the operating lever in the direction of rotation against each other to change a mixing ratio between hot and cold water, and can be moved parallel to each other to open a valve opening or close / reduce.

Here, too, the same advantages in the use of the hand shower that this namely with downward-pointing handle end 6 in approximately horizontally or the slightly obliquely upward-pointing outlet pipe following can be pulled forward. Since the handle is shaped pistol-like, it is intuitively enclosed in the operation with the closed fist. The finger lying around the handle so u.a. The index and middle fingers come here to lie on the Umsetzaste 7, so that a beam change in the operation intuitively and ergonomically.
