  • Another object of the invention is to allow this concentration to be automatically restored. predetermined.
  • the device is provided with adjustment members associated with the flushing solenoid valve to control the operation of the engine for a predetermined time and consequently the distribution in the washing tub. a quantity of detergent or cleaning product determined so as to compensate for the loss of this product following the addition of water during the rinsing operation.
  • the passage of water through the rinsing solenoid valve automatically causes the device to dispense a quantity of washing or cleaning product making it possible to restore the initial concentration thereof in the washing tub.
  • the electronic circuit is equipped with a dosing potentiometer cooperating with a push button or a manually controlled switch to control the starting of the engine and to variably adjust its operating time, thus as an automatically controlled adjustment potentiometer forming an integral part of the adjustment members and making it possible to adjust the duration during which a predetermined quantity of washing or cleaning product is dispensed so as to dose this quantity as a function of the volume of water of the wash tank and the necessary concentration.
  • this adjustment potentiometer cooperates with a magnetic field contactor sensitive to the passage of water in the flushing solenoid valve and cooperates with the adjustment potentiometer to control the starting of the engine and its operation. pen for a predetermined duration.
  • the adjustment members are constituted by the second potentiometer and by the magnetic field contactor which is fixed in the immediate vicinity of the rinsing solenoid valve in order to be able to detect the magnetic field at the level thereof.
  • the speed of rotation of the motor is variable.
  • This variation naturally entails automatically the variation in the quantity of washing and cleaning product dispensed during the predetermined times.
  • This characteristic is also particularly advantageous, since it makes it possible to vary the predetermined concentration in the washing tub, for example, as a function of the degree of '' dirt '' of the dishes to be washed.
  • the aforementioned device may include other members, in particular a timer or an optical battery voltage warning device indicating that the battery voltage reaches a minimum, without thereby departing from the scope of the invention.
  • the object device of the invention is integrated in two boxes 1 and 2 mounted side by side on a rear wall 3 comprising elements for fixing to a wall shown in hatched form.
  • These fixing elements consist of a slide 4 which cooperates with a fixing rail 5 which is fixed to the wall by means of screws 6 as shown in FIGS. 2 and 3.
  • Each of the housings 1 or 2 is constituted by a main part 7, 7 ′ provided at its front part with a cover 8, 8 ′ mounted articulated around an axis 9, 9 ′ making it possible to raise it.
  • This device is intended to allow the distribution of preset doses of washing or cleaning product to installations such as manual immersion tanks or industrial or domestic dishwashers from a metering pump 10 in particular of a peristaltic pump by means of distribution pipes 11 and supply 12 of washing or cleaning product; the supply line 12 is connected to a reservoir 13 containing the product to be dispensed which is shown diagrammatically in FIG. 4.
