Definitions

  • the invention relates to a sanitary mixing valve a metallic, cast valve body, the one Cold water inlet hole, a hot water inlet hole and has a mixed water outlet opening and in the a cold water path starts from the cold water inlet opening, who at a union of cold and Hot water is merged with a hot water path, which starts from the hot water inlet hole.
  • Such sanitary mixing valves are available in large numbers known.
  • thermostatic valves on the market where the association is located of hot and cold water within a thermostat element located in the valve housing or screwed in.
  • the water-bearing spaces inside of the valve body are essentially by cast, metallic inner and outer walls of the valve body limited. If so, as is the case with Thermostatic valves are common to the hot water path inside of the valve housing has a considerable length before the combination with the cold water takes place, this can cause the valve housing in such Dimensions on its outer surface warmed that it could cause burns of the user or at least to startle reactions comes.
  • the object of the present invention is a sanitary To design the mixing valve of the type mentioned at the beginning, that an impermissibly high heating of the valve housing no longer occurs.
  • the present invention lies between the hot water path and the outer wall of the valve housing itself a room through which mixed water flows, which is the hot water path isolated and so overheating of the valve housing avoids. So there are no longer all waterways limited by molded outer walls on the housing. In this way there are burns or startling reactions of the user of the sanitary mixing valve no longer expect.
  • An advantageous embodiment of the invention is characterized is characterized in that the hot water path within the Valve housing at least predominantly from a pipe or Hose made of poorly heat-conducting material is. This leaves due to its poor thermal conductivity a transfer of heat from the hot water to the surrounding mixed water and from there to the valve housing only limited to. The short distances on which that Hot water, e.g. in the area of the hot water inlet opening, still flows through the material of the valve housing itself, suffice for an inadmissibly high heating of the valve housing no longer out.
  • the pipe or the hose expediently exists made of plastic.
  • the thermostatic valve housing shown in the drawing 1 is an essentially cylindrical cast brass part, which has an inlet bore 2 for cold water and a Has inlet bore 3 for hot water.
  • the inlet holes 2, 3 are in operation with the thermostatic valve connected to the corresponding house management.
  • the cold water inlet bore 2 is ring-shaped Cold water distribution room 4 in connection, which in turn again with a stepped, to the right End of the thermostatic valve housing 1 opening Receiving hole 5 for the thermostat control element communicates.
  • the hot water inlet bore 3 is with a tube 6 made of poorly heat-conducting material, for example Plastic, in connection, whose left in the drawing End inserted into a bore 8 of a housing wall 9 is.
  • the tube 6 is against the bore 8 of the housing wall 9 sealed by an O-ring 10.
  • O-ring 10 In corresponding Way is the right end of the drawing in the drawing Tube 6 into a bore 11 of a housing wall 12 inserted and sealed against this by an O-ring 13.
  • the bore 11 in the housing wall 12 is with a annular water distribution space 14 for hot water in Connection that is at an axial distance from the cold water distribution room 4 also with the mounting hole 5 for the thermostat element communicated.
  • Thermostat element not shown in the drawing is designed so that after screwing in the receiving hole 5 the cold water from the cold water distribution room 4 and the hot water from the hot water distribution room 14 separately and, accordingly a target temperature that can be preselected on a handle, Deliver in the axial direction, to the left in the drawing can.
  • the construction of such thermostatic elements is on and known for itself; can therefore on a description to be dispensed with here.
  • the receiving hole 5 for the thermostat member leads inside the thermostatic valve housing 1 to a mixed water transfer space 15, of that described above bad heat-conducting tube 6 is penetrated.
  • the Mixed water transfer space 15 With a receiving hole 16 for a flow control valve 17 in connection.
  • the quantity regulating valve 17 is different from the thermostatic element shown schematically in the drawing. It includes coaxial controls for the water flow, ceramic disks rotatable relative to one another, such as this and is known for itself.
  • the inlet opening of the volume control valve 17 is axially centered on the the mixed water transfer space 15 facing the end of Receiving space 16; the outlet opening 18 of the flow control valve 17 is also axially directed, however positioned off-center.
  • thermostatic valve which consists of through the thermostatic valve housing 1 shown in FIG Screwing the thermostat element into the mounting hole 5 is obtained is the following:
  • the cold water coming from the house management is from the cold water inlet bore 2 in the cold water distribution room 4 out and from there according to the position the thermostat control element is mixed with the hot water, which via the hot water inlet bore 3, the pipe 6 and the hot water distribution chamber 14 flows.
  • This in axial direction in the mixed water transfer space 15 flowing mixed water is then ideally on the on the handle of the thermostat link set target temperature.
  • the mixed water flows from the mixed water transfer space 15 accordingly the position of the ceramic discs within the flow control valve 17 into the mixed water outlet space 19, from there to the outlet opening 21 and to this connected consumers.
  • thermostatic valve housing 1 Due to the fact that the hot water is at its greatest Part of the way through the thermostatic valve housing 1 not in direct contact with its good thermal conductivity Instead, material stands through the mixed water transfer room 15 and the poorly heat-conducting pipe 6 is insulated, the thermostatic valve housing 1 heat up relatively little. The outer surface of the Thermostat valve housing 1 therefore remains proportionate cool; there is a risk of burns when touched no more.
