Definitions

  • the invention relates to a cleaning device for the piping system of a whirlpool tub containing a circulation pump, with at least one suction opening provided in the tub wall and with one or more outlet valves, also fixed in the tub wall, connected to a pressure line, each with a nozzle for the supply a water-air mixture in the tub interior, which is connected to a drain line via a closable drain opening in the tub floor, each outlet valve being a valve housing, an approximately cylindrical nozzle body which delimits the nozzle channel and which is connected via an external thread stored in the valve housing and thus axially displaceable, and takes place in the air supply on the outlet side of the outlet valve, and comprises a central nozzle core, the valve of which is closed when it is seated on a valve seat assigned to it and which has the outlet cross section due to relative axial displacement with respect to the seat releases more or less for the water-air mixture.
  • the invention has for its object to provide a cleaning device of the type mentioned, with the help of a simple, safe, yet inexpensive way to achieve a perfect cleaning of the pipe system immediately before normal "whirl bath” operation.
  • the cleaning device is essentially characterized in that the nozzle core is connected to a membrane controlling it, that the membrane continuously acted upon in the closing direction on the side remote from the nozzle core, the first valve housing space is limited, which is connected to the pressure line via a first solenoid valve that determines the duration of the closed state of the outlet valve, that disinfectant can be supplied to the suction line via a metering valve, and that between the pressure line led through all outlet valves and the Drain line a drain line is provided with a second solenoid valve switched on, the opening time of which is longer than that of the metering valve, so that the outlet valves together with the pipe system can be flushed with disinfectant immediately before use of the bath.
  • This facility ensures that immediately before using the bathroom, i.e. Commissioning of the nozzles of the outlet valves, the latter, together with the pipe system, are carefully rinsed under relatively high pressure and with the addition of disinfectant.
  • the duration of the disinfectant addition and the duration of the rinsing process can be easily predetermined by simple control of the solenoid valves to ensure that when the rinsing process is finished and the outlet valves are put into operation, there are no more disinfectant residues in the pipe system and can get into the tub.
  • the membrane is assigned a spring which acts on it in the closing direction of the nozzle core. This perfectly ensures the desired closing state during purging, which is canceled after the flushing process by pressurizing the first valve housing space by compressing the spring. It has proven to be very expedient, however, if the membrane separates the first valve housing space from a second valve housing space, which is located on the side facing the nozzle core and is directly connected to the pressure line. The spring can then be dimensioned very weak because the pressure in the second valve housing space also ensures the required closing status during the cleaning process.
  • the nozzle channel provided in the nozzle body tapers approximately conically towards the central region of the nozzle body before it widens toward the outlet side, forming the valve seat for the nozzle core.
  • it is not a nozzle that is angled from the pressure line channel and formed in the valve housing with its free edge that forms the valve seat, but rather the narrowing of the nozzle channel in the nozzle body. Since the latter is screw-mounted in the valve housing via its external thread and is therefore axially adjustable, the average cross section can be changed as desired by turning the valve body when the outlet valve is open through the membrane.
  • a very pleasant handling of the outlet valve results if, in a further embodiment, the nozzle body is screwed into a threaded bore of a bearing ball, which is pivotably mounted in the valve housing, since in this way the direction of the water-air mixture jet can be freely selected within certain limits, that is changeable.
  • the pressure line discharges the cleaning liquid supplied to the outlet valves via the suction line to the drain line, partial areas of the air supply channels of the outlet valves can remain more or less unpurged. It is therefore particularly favorable if, in a further embodiment, the air supply ducts of a plurality of outlet valves are connected to one another via an air line and that the pressure line can be connected to the drain line via the air line and the outlet line.
  • the cleaning liquid then passes through the suction line, the circulation pump, the pressure line with the connected outlet valves and the air line leading into the housing, from which the cleaning liquid is released into the drain line. This circuit ensures that the piping system is cleaned particularly thoroughly.
  • the whirlpool tub 1 is associated with a pipe system 3 comprising a circulating pump 2.
  • a suction line 4 which leads to a suction opening 5 in the Tub wall 6 leads, as well as a pressure line 7 to which a plurality of outlet valves 8 are connected.
  • a drain opening 9, which can be closed in a conventional manner is provided in the tub floor 10 and leads to a drain line 11.
  • the outlet valves 8 are also connected to one another via an air line 12 which ensures the air supply to the outlet valves 8.
  • a mixture of the water supplied via the pressure line 7 with the air takes place in the outlet valves 8 before this mixture exits under pressure into the tub, provided a first solenoid valve 13 (FIG. 1) controls the outlet valve in the manner described below.
  • a storage container 15 for a disinfectant which can be introduced into the suction line 4 via a metering valve 15a designed as a solenoid valve in the area of the suction opening 5.
  • a discharge line 16 is provided between the pressure line 7 led through all the outlet valves 8 and the discharge line 11, into which a second solenoid valve 17 and a throttle 18 are connected.
  • a connecting line 19 with a third solenoid valve 20 is provided between the inlet side of the second solenoid valve 17 and the suction line 4.
  • the second magnetic valve 17 can also be connected to the air line 12 via a line section 21 instead of to the suction line 4.
  • each outlet valve 8 comprises a valve housing 22, an air supply duct 23, an approximately cylindrical nozzle body 25 delimiting the nozzle duct 24, and a central nozzle core 26.
  • the air supply duct 23 connected to the air line 12 opens into an annular chamber 27 directly adjacent to the inlet side of the nozzle body 25.
  • This annular chamber surrounds one formed in the valve housing, angled from a pressure line channel 28, which extends with its edge 30 to the nozzle channel 24. If the nozzle channel 24 is open, the water flowing in from the pressure line channel 28 sucks in air from the annular chamber 27, which mixes with the water as it passes through the nozzle body 25. As indicated by arrows 30, this mixture emerges from the nozzle parallel to the axis.
  • a membrane 31 is clamped in the valve housing 22 by means of a connecting piece 32.
  • This membrane 31 is connected to the nozzle core 26 via a control rod 33.
  • the nozzle channel 24 provided in the nozzle body 25 tapers approximately conically towards the central region before it widens toward the outlet side, forming the valve seat 34 for the nozzle core 26.
  • a coil spring 35 which is connected between the diaphragm 31 and the valve housing 22 and surrounds the control rod 33. acts on the membrane and, via the control rod 33, the nozzle core 26 constantly in the closing direction, and the nozzle core 26 rests on the valve seat 34.
  • the membrane 31 delimits a first valve housing space 36 located on the side remote from the nozzle core.
  • the valve body 35 is provided with an external thread 40, via which it is screwed into a corresponding threaded bore in the valve housing 22.
  • the valve body 25 is axially displaced relative to the nozzle core 26. In this way the pressure cross section can be regulated.
  • valve body 25 In order to enable the valve body 25 to pivot relative to the valve housing 22, it is not screwed directly into a threaded bore of the valve housing but into a threaded bore of a bearing ball 41, which in turn is pivotably mounted in the valve housing 22.
  • a bearing ring 42 which can be screwed into a threaded bore 43, serves to hold this bearing ball 41 on its spherical seat. So that the control rod 33, which practically only has to transmit tensile forces, does not oppose pivoting of the nozzle core 26 together with the valve body 25, it is made of an elastically flexible material, preferably of plastic.
  • valve housing 22 can be fixed in a trough bore 45 via a flange threaded ring 44.
  • suction line 4 is connected to the whirlpool tub 1 via a suction fitting 46 which prevents backflow.
  • This suction fitting comprises on the side a suction basket 47 with passage openings 48, on the inside of which an elastically flexible plate valve body rests.
  • An elastic support plate 50 serves to act on the resilient plate valve body 49 and ensures that it rests on the suction basket 47.
