Definitions

  • the invention relates to a safety device for sanitary installations.
  • sanitary facilities for example a mixing valve with a bath spout and a shower can be understood.
  • a pure shower device with one or more showers are understood.
  • the invention has for its object a safety device to create sanitary facilities that are simple is constructed and manages with little additional effort.
  • the invention proposes a safety device with the features of claim 1. Developments of the invention are the subject of the dependent claims.
  • the changeover element thus serves when a critical temperature to turn off the water outlet. In order to there is a risk of injury to the user removed hot water.
  • the changeover element is therefore part of the sanitary fitting, For example, a changeover element that is between a shower outlet and switches a tub outlet.
  • a changeover element which is a changeover valve is formed by a temperature sensitive element mechanically loaded. This is the sanitary facility easy to set up.
  • the changeover element is of course only in the mentioned switched one position if it was previously in the other Position. In the following, this position is intended as a safety position be designated.
  • the one assigned to the safety position of the changeover element Water flow can lead to any facility that assumes a safety function.
  • the security position assigned water supply leads to a water outlet that less or no risk for a user represents.
  • the temperature element is designed such that the changeover of the changeover element suddenly at the limit temperature is effected. This eliminates the disadvantage of State of the art avoided, namely with slowly increasing Temperature of the flow cross section, for example shower device is gradually reduced.
  • the invention proposes as a possibility that Changeover element after changeover, even if it drops again Temperature remains in the safety position. Then it must be in in this case by hand or by another device if the original position to be taken again.
  • the changeover element manually to switch between the two water channels in is operable in at least one direction.
  • the changeover element can be one act so-called automatic shower diverter.
  • This shower diverters are placed in the shower outlet by hand assigned position and remain in this position then as long as the water flows. You will namely in this position held by the water pressure.
  • the shower diverter is spring-loaded into the bath spout assigned position pushed back.
  • Invention now particularly useful and simple, because the Then temperature sensors only act on the shower diverter needs and only move it by a small amount got to. It opens even with a small shift Tub outlet, and the water pressure does not hold the diverter more in its shower position, so that the diverter then already from the spring into the one corresponding to the bath spout Position is brought.
  • the bathtub spout is a smaller one Danger to the user than the shower.
  • the safety position assigned water flow to a bath spout leads, for example a bathtub spout or a shower tray spout, which can be arranged in the foot area can.
  • the user can first on one Thermostat set the temperature of the shower water and with check the foot until it finds the right temperature and then actuated the shower diverter to take a shower.
  • the water supply assigned to the safety position directly the tub drain, both in a bathtub and with a shower tray. In this case, the user can do not come into contact with water that is too hot.
  • the Changeover element in the starting position when the temperature drops again is deferred. This is especially so an advantage if the one assigned to the safety position Water flow leads to an unusable water outlet.
  • the temperature sensitive Element has a bimetal, in particular one Bimetal spring. Especially when the changeover element is built like a shower changer, a Bimetal element is sufficient when the limit temperature is reached the changeover of the diverter only to be triggered by the existing spring or because of the no longer unilateral water pressure completely changes the valve.
  • temperature sensitive element can be, for example Wax element can be used.
  • the invention also proposes to be temperature sensitive Element an element made of a so-called memory alloy to use, for example a spring.
  • This material which is called Shape Memory Alloy (SMA) has the Property, in a very narrow temperature range perform sudden movement, so here too the effect the gradual closing of an opening is avoided.
  • SMA Shape Memory Alloy
  • the only drawing figure shows a partial section through a fitting housing with one inserted therein automatic shower diverter.
  • the drawing shows a horizontal part 1 a sanitary fitting, into which a mixing valve incoming water enters through a channel 2 and out of it right through a first water supply 3, for example a tub spout and through a second water supply 4 can reach a shower outlet.
  • a first water supply 3 for example a tub spout and through a second water supply 4 can reach a shower outlet.
  • the shower diverter 6 inquires the top of the sanitary fitting out of this and points there an operating handle 7.
  • the left half of the shower diverter is drawn in a position in which the to the shower connection 8 leading water supply 4 with water is supplied while the right half of the shower changer 7 shows the position in which the to a tub spout leading water supply 3 is supplied with water.
  • the shower diverter 6 contains a movable Valve rod 9 on which to switch between the two water channels 3, 4 a valve closure body 10 is attached, which has a circumferential seal 11.
  • a valve closure body 10 in the middle part of the shower diverter 6 is an opening in the partition wall 5 filling transverse wall 12 with a central Opening formed. The edge area of this opening at the The underside of the transverse wall 12 forms one with the seal 11 interacting valve seat.
  • valve closure body 10 extends around the Valve rod 9 around a helical compression spring 13 which the shower diverter 6 in a position in which the shower outlet is closed because the valve closure body 10 with the seal 11 on the formed on the shower outlet 8 Valve seat is seated.
  • valve rod 9 At the lower end of the valve rod 9 is one with openings 14 provided disc 15 attached.
  • the disc is downstream the valve seat in the shower connection 8.
  • a second helical compression spring 17th Between a downstream the valve seat for the shower port 8 located shoulder 16 and the disc 15 is a second helical compression spring 17th arranged.
  • This helical compression spring 17 forms a temperature sensitive element because it consists of SMA, i.e. a memory alloy. Likewise a bi-metal element, a wax element or the like is possible
  • the shower diverter 6 is from below in the openings of the Fitting housing used and from above with the help of a Union nut 18 set. They are used for sealing different O-rings.
  • At the lower end of the shower connector 8 can be there existing external thread 19 a shower hose or a further line can be connected.
  • the operation of the arrangement shown in the figure is the following.
  • the shower outlet 8 is supplied with water when it is open Mixing valve of the shower diverter 6 by pulling the operating handle 7 moved up.
  • the water pressure acts on the Underside of the closure body 10 and holds the diverter against the action of the helical compression spring 13 in this Position firmly.
  • the water flows to the shower outlet 8.
  • the temperature-sensitive helical compression spring 17 is dimensioned that in a tolerable for a user Temperature of the shower water no spring force is generated.
  • the compression spring 17 made of SMA also replaced by a compression spring made of bimetal be provided that care is taken that the increase in temperature caused expansion of the bimetal only at the Limit temperature for a displacement of the valve rod 9 leads.
  • This can be achieved, for example, in that the bimetal helical compression spring in the left in the figure shown condition a smaller axial extent has, that is not yet against the shoulder 16.
  • a shower diverter shown as part of a sanitary fitting between a Bath outlet and a shower outlet switches.
