Definitions

  • the present invention relates to a shower head with a spray disc, which has at least two separately controllable groups of outlet openings, and with a switching device for switching between the two groups of outlet openings, the switching device comprising a spring and an actuating element, the actuating element in stable rotary positions Establishes or blocks the flow connection between an inlet and at least one of the groups of outlet openings depending on its stable rotational position, is rotatably movable between the stable rotational positions for switching, and is biased at least in the stable rotational positions in the direction of a seat by means of the spring.
  • a switchover device of a shower with the aforementioned features is, for example, from DE 10 2009 008 194 B4 is known in which the actuating element referred to as the valve closing body performs a lifting movement during the rotary movement for switching between two stable rotary positions, so that the valve closing body is lifted off the valve seat in order to eliminate the increased friction between the valve closing body and the valve seat for the switching due to the spring action. It has been found that the force required to actuate the switching device is still relatively high.
  • the object of the present invention is therefore to provide a shower with a switching device in which the switching device can be actuated with little effort.
  • the switching device comprises a plunger which is mounted so as to be axially movable with respect to the actuating element and which uncouples the actuating element from the spring during the rotary movement between two stable rotary positions.
  • the basic idea of the invention therefore provides that the plunger absorbs the force provided by the spring during the rotational movement for switching the actuating element and thus relieves the actuating element of the spring action, so that the spring does not act on the actuating element during the rotational movement of the actuating element.
  • the switching device and in particular the plunger is preferably designed such that the plunger is offset linearly against the spring force and in the axial direction relative to the actuating element during the rotational movement, so that the spring does not place the actuating element on the (valve) seat during the rotational movement suppressed.
  • the switching device in particular also includes a (valve) seat, onto which the actuating element is pressed by means of the spring in the stable rotational positions.
  • the adjusting element connects the water inlet to an opening or a group of openings in the valve seat, the one opening or the group of openings in the valve seat being assigned a group of outlet openings in the spray disc of the shower.
  • the actuating element is in particular plate-shaped and has one or more passage openings which are arranged in the corresponding stable rotational positions in relation to the passage opening or a group of passage openings in the valve seat, so that the water through the passage openings in the adjusting element and the corresponding passage openings in the valve seat can flow.
  • At least one seal can be formed between the actuating element and the valve seat, which surround the openings.
  • a flat sealing layer having recesses corresponding to the passage openings is arranged on a side of the actuating element facing the valve seat, and that the passage openings of the valve seat are each surrounded by a projection which runs around the passage opening and onto which the sealing layer is indirectly held by the spring is pressed in the stable rotary position.
  • the seals between the actuating element and the valve seat are designed in particular in such a way that, in the stable rotational positions, the area exposed to water on the upper side of the actuating element facing the inlet is larger than on the opposite underside, so that in the stable rotational positions the actuating element is also due the force difference is pressed onto the valve seat.
  • the plunger is preferably arranged directly between the spring and the actuating element, so that the plunger transfers the spring force directly to the actuating element in the stable rotational positions.
  • further components are provided for the power transmission from the spring to the actuating element.
  • another component transmits the force from the spring to the actuating element, the plunger relieving the actuating element of the spring force due to its axial movement during the rotational movement.
  • the plunger transmits the rotary movement caused by the actuation of the switching device to the actuating element, for which purpose the plunger is connected to the actuating element in a rotationally fixed manner.
  • the plunger is therefore preferably axially movable, but non-rotatably connected to the actuating element, for which purpose the plunger and the actuating element preferably have mutually corresponding form-fitting designs for the rotationally fixed connection.
  • the plunger can, for example, be inserted into an opening in the actuating element, the plunger and the opening having complementary projection and recess configurations oriented in the radial direction, as a result of which an axial relative movement to one another is possible, while the actuating element and the plunger are oriented transversely to one another Rotational movement are coupled together.
  • the tappet has at least one elevation projecting in the direction of the seat on an end face facing the (valve) seat, at least one elevation projecting in the direction of the tappet being formed on the seat, so that during the Rotary movement of the plunger, the ridges one above the other, whereby the plunger is axially lifted against the spring force from the actuating element.
  • the plunger has in particular a collar, via which the spring prestresses the actuating element in the stable rotational positions by means of the plunger.
  • the collar extends in particular as at least one projection aligned in the radial direction, which preferably extends in one piece around the entire circumference of the tappet.
  • the spring is preferably arranged at least in sections within the plunger.
  • the plunger can have a receptacle for the spring, for example in the form of a bore, the spring being supported above the receptacle on a counter stop, for example on a housing of the shower.
  • the switching device preferably comprises a gearwheel which can be driven to rotate by means of at least one drive element having at least one tooth-shaped projection.
  • the at least one drive element can be driven, for example, by a push button at least indirectly, possibly with the interposition of a gear, preferably to a linear movement.
  • the gearwheel is only rotated when the drive element moves linearly in one direction, whereas the gearwheel is not driven when the drive element moves linearly in the opposite direction.
  • the tappet is connected to the gear wheel in a rotationally fixed manner is so that a rotary movement of the gearwheel triggered by actuation of the push-button is translated into a rotary movement of the plunger, the plunger being lifted axially from the actuating element during this rotational movement, for which purpose the plunger is arranged to be linearly movable in relation to the gearwheel in the axial direction.
  • the shower shown comprises a switching device 2 which can be actuated by means of a push button 13.
  • the switchover device 2 also comprises a drive element 12 which has tooth-like projections and can drive a gearwheel 11 of the switchover device 2 in a rotational movement.
  • the drive element 12 is connected to the pushbutton 13, so that by actuating the pushbutton 13 the drive element 12 executes a feed movement by which the gearwheel 11 is driven.
  • the gearwheel 11 is connected in a rotationally fixed manner to a tappet 7, so that a rotational movement of the gearwheel 11 is converted into a rotational movement of the tappet 7.
  • the plunger 7 is spring-loaded in the direction of a seat 6 by means of a spring 3.
  • the plunger 7 has a collar 10 with which the plunger 7 is an adjusting element 4 in the Figure 1 shown stable rotary position presses on the valve seat 6.
  • control element 4 has two through openings 14.
  • the valve seat 6, on the other hand, has three passage openings 15 (see Figure 4 ).
  • the switching device 2 is now designed such that the actuating element 4 can be brought into six stable rotational positions. In each of the six rotational positions, one of the passage openings 14 of the actuating element 4 is aligned with a passage opening 15 in the seat 6. Each of the passage openings 15 is assigned a group of outlet openings in a jet disc 1, so that the water flows from an inlet 5 as a function of the stable rotational positions one of the three groups of outlet openings in the jet disc 1 flows.
  • the actuating element 4 has a flat sealing disk on its underside, while the passage openings 15 in the seat 6 are surrounded by projections, so that the passage openings 15 are sealed off from the actuating element 4 in the stable rotational positions.
  • the passage openings 14 and the projections surrounding the passage openings 15 are dimensioned such that, in the stable rotational positions, the surface area on which the water acts on the upper side of the actuating element 4 is larger than that on the upper side of the actuating element 4 Bottom acted surface, so that the actuating element 4 is pressed on the seat 6 due to the water pressure.
  • the plunger 7 is mounted so that it can move axially relative to the actuating element 4.
  • the plunger 7 and the actuating element 4 have complementary form-fitting configurations 8, which couple the plunger 7 to the actuating element 4 in a rotationally fixed manner, but allow the plunger to move relative to the actuating element 4 in the axial direction against the spring force.
  • elevations 9 are formed on an end face of the plunger facing the seat 6, while complementary elevations 9 are formed on the seat 6.
