Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known for example from DE-U-85 32 878.
  • a hand switch is provided for the operation of this device, with which the electric motor for the circulating pump can be switched on or off.
  • An optimal treatment result can only be achieved if the required treatment time is not exceeded, e.g. B for the fixation treatment of hair treated with perm. This is only guaranteed by the fact that the user of such a device must additionally operate and read a separate stopwatch in order to then switch the device off manually.
  • the invention has for its object to provide a device according to the preamble of claim 1, in which the required treatment time is controlled automatically.
  • the end of treatment signal transmitter is preferably arranged in or on the circulation pump unit.
  • the invention makes the changing electrical conductivity or pH of the fixing treatment liquid to use, because it can be assumed that the fixing treatment is to be considered complete when the electrical conductivity or the pH of the fixing liquid no longer changes significantly.
  • a conductivity sensor or a pH sensor is provided, which controls the device that determines the duration of the treatment depending on an electrical conductivity or treatment liquid that no longer changes significantly.
  • suitable substances salts can also be provided which have a more pronounced conductivity or pH characteristic, in order to optimize the measuring method according to the invention, if necessary.
  • the conductivity sensor or the pH sensor is preferably integrated in the circulation pump unit in the circulation circuit, e.g. B. in the form of a hose adapter.
  • a measuring device for determining the end of treatment, which forms measured values at constant intervals after the start of treatment and continually compares two measured values lying next to each other, whereby at a predetermined difference value the Device for switching off is controlled.
  • the measuring device forms average values from a predetermined number of measured values at constant measuring intervals and compares them with the following average value, the device being actuated at a predetermined difference value.
  • This measuring method has the advantage that an incorrect value does not immediately lead to the end of operation of the device, but has little effect due to the average values formed.
  • a predetermined difference value of average values has to be confirmed again in order to end the treatment process only then.
  • FIG. 1 shows a device 1 in a working position, a circulation pump unit 2 being connected via a foot 3 with a stopper 4 to a drain opening 5 of a sink 6.
  • the circulation pump unit 2 has a pump 8 driven by an electric motor 7, the electric motor 7 being supplied by accumulators 9. Below the pump 8 there is an intake opening 10, to which a filter 11 is placed.
  • An outlet channel 12 of the pump 8 is connected to a hose 13, on the other hand connects a hose connector 14.
  • a conductivity sensor 16 or pH sensor 16 A is inserted into this hose 13.
  • a treatment start switch 18, a measuring and control device 19 and a treatment duration determining device 20 are arranged inside.
  • An acoustic and / or visual display 22 is arranged on the control panel 21 of the circulation pump unit 2.
  • the circulation pump unit 2 is in contact with the suction opening 10 of the pump 8 with a liquid 23 which is used for treating hair in a circulation process, an outlet opening 24 being connected to a hose 13 'which is connected at its other end to a shower head (not shown) is.
  • FIG. 2 shows a top view of the circulation pump unit 2 with the control panel 21.
  • the control panel 21 is here provided with a plurality of treatment start switches 18, 18 ⁇ , 18 nie and has an off switch 26 and a stop switch 26 ⁇ .
  • a charge status indicator 32 is provided for the batteries 9.
  • the switch 18, 18 ⁇ , 18 ⁇ the device 1 is put into operation by switching on the electric motor 7 via the device 20 that determines the duration of the treatment. After the specified treatment time has expired, the device 20 switches the motor 7 off again. During treatment, the device 1 can be switched off in the event of danger using the stop switch 26 ⁇ .
  • Fig. 3 shows a block diagram for an automatically running treatment time by means of various sensors 16, 16 A, 17.
  • a measuring and control device 19 is provided which is connected at the input to a conductivity sensor 16 or a pH sensor 16.
  • the measuring and control device 19 is connected to a device 20 that determines the duration of treatment, which controls the electric motor 7 for the pump 8.
  • the measuring and control device 19 is activated and switches on the electric motor 7.
  • the conductivity sensor 16 is used to detect a conductivity state of the circulating liquid 23, and the fixing treatment can then be regarded as complete when the measured conductivity values or pH values no longer change significantly, for which purpose the electric motor 7 is then switched off via the device 25. Further treatment start switches can be provided for different hair qualities or quantities in order to achieve a correspondingly automatically adjusted treatment time.
  • FIG. 4 shows an axial section of a conductivity sensor 16 which is provided with two electrodes 27, 27 'lying opposite one another.
  • the arrow 28 indicates the flow of the liquid 23.
  • the conductivity sensor 16 has hose connections 29, 29 ⁇ on both sides, with which it can be inserted into a hose 13.
  • the conductivity sensor 16 is shown in a section A - A ⁇ according to FIG. 4.
  • the electrodes 27, 27 ⁇ are provided with electrical connections 30, 30 ⁇ and lead to the measuring and control device 19th
  • a measurement diagram for determining the automatic end of treatment is shown in FIG. 6.
  • the conductivity values or pH values are converted into proportional voltage values.
  • FIG. 7 A corresponding measuring circuit for converting conductivity values into voltage values is shown in FIG. 7.
  • the conductivity sensor 16 and measuring resistor 31 are supplied with a supply voltage U B in series .
  • the voltage U a tapped at the measuring resistor 31 is fed to the measuring and control device 19 for further processing.
