Definitions

  • the invention relates to steam ironing plants comprising an iron equipped with a heating soleplate having steam outlet holes, a steam generator communicating with said steam holes, an independent water tank, a pump electric comprising a casing and a movable member for driving the water between an inlet orifice connected to said water tank and a discharge orifice connected to said steam generator, as well as a water treatment means intended in particular to demineralize it.
  • forced displacement pumps are used, for example, peristaltic pumps or pumps of the electromagnetic type with plunger core which include bi-flaps -directional preventing any free circulation of water through the casing when they are not working. Consequently, in order to avoid the drawbacks due to an overpressure in the steam generator when the steam holes scale up, it is necessary to install load-shedding safety devices, safety of the valve type, calibrated valve, which are generally expensive and difficult to control. In addition, these pumps manage to prime when the water tank is empty and it is impossible to prime them as long as there is back pressure. in the steam generator.
  • the object of the invention is in particular to eliminate these drawbacks, and to reduce the cost of manufacturing ironing plants.
  • the pump has a free circulation of water between the two inlet and outlet ports at least when the drive member is at rest.
  • the pump is of the centrifugal type and the movable member consists of an impeller secured to a drive shaft and rotatably mounted in the casing with at least one peripheral clearance.
  • the water treatment means is mounted in the pipe between the steam generator and said pump.
  • the water treatment means can be placed in the iron, which was made impossible in earlier plants since it was necessary to demineralize the water upstream of the pump in order to avoid scaling of metallic pump elements such as springs and valves.
  • the steam ironing center comprises an iron 1 equipped with a heating soleplate 2 having holes 3 for steam outlet, a steam generator 4 communicating with said steam holes 3, a tank independent water 5 whose housing 6 has a filling opening 7 closed by a vent plug 8 shown diagrammatically in broken lines, an electric motor pump 9 comprising a casing 10 and a movable internal member 11 for driving the water between an inlet orifice 12 connected to said reservoir and a discharge orifice 13 connected, by a pipe 14 to the steam generator 4, as well as a means 15 for treating the water intended in particular for demineralizing it.
  • the steam generator 4 is integrated into the iron 1 and is equipped, in a manner known per se, with a device for drip water flow comprising a small chamber 16 whose outlet orifice 17 is provided with an adjustable needle 18 and whose inlet orifice is connected by the pipe 14 by means 15 of water treatment.
  • a device for drip water flow comprising a small chamber 16 whose outlet orifice 17 is provided with an adjustable needle 18 and whose inlet orifice is connected by the pipe 14 by means 15 of water treatment.
  • the steam generator 4 could be independent of the iron and installed on the pipe 14 or in the housing 6 of the tank modified for this purpose.
  • the pump 9 has a free circulation of water between the two inlet 12 and discharge 13 ports at least when the drive member 11 is at rest.
  • the pump 9 is of the centrifugal type and the movable member 11 is constituted by a paddle wheel secured to a drive shaft 19 and rotatably mounted in the casing 10 with at least one peripheral clearance (referenced by e in FIG. 1), said casing 10 having the intake orifice 12 arranged axially, and the discharge orifice 13 arranged at its periphery.
  • pumps known per se can be used as the pump for free circulation of water in which the drive member, vanes or rollers, rubs against the casing under the effect of centrifugal force when it is in motion, and plays a game when it is at rest under the effect of an elastic recall.
  • the centrifugal pump 9 used is of the vertical type with submerged casing and is mounted for this purpose in a well 20 formed in the housing 6 of the tank 5 with its suction inlet 12 facing towards the bottom of said reservoir.
  • the casing 10 is located near the bottom of the tank and is mounted in leaktight manner in the well 20 by means of a peripheral seal 20 '.
  • the impeller 11 is always submerged when the tank is filled with water.
  • the pump 9 is self-priming, and the casing 10 has for this purpose an additional degassing opening 21 arranged on the upper wall of the casing through which the motor shaft 19 passes.
  • the air having accumulated in the casing 10 can escape under the pressure of the water through the opening 21, allowing the impeller 11 to be submerged again.
  • the advantages linked to the use of a pump with free circulation of water of the centrifugal type for example are in particular: reduction in the manufacturing cost of the power station; reliability of the pump due to the absence of valve and spring; practically empty operation of the pump; safety ensured in the event of overpressure of vapor in the pipeline; regular flow of water at the outlet of the pump without harmful pulsation for the needle 18 and the chamber 4, as in the case of an electromagnetic pump.
  • the means 15 for treating the water is mounted in the pipe 14 between the steam generator 4 and the pump 9, and comprises a cassette 13 comprising at least one filter 22 arranged at the outlet of water and a demineralization product of water such as a resin.
  • the cassette 13 comprises two filters, the filter 22 and a filter 23 arranged at the inlet of the cassette and intended to retain the impurities contained in the water of the tank.
  • this cassette 15 is installed in the housing 6.
  • the cassette 15, (shown in broken lines), is arranged in said iron iron 1 and is removably mounted, in a manner known per se, to allow its exchange when the resin is saturated. This arrangement allows, in addition to placing the cassette in the iron for a better view of its state of saturation, to install the pump 9 as close as possible to the bottom of the tank 5 so as to facilitate its priming and the pressurization of the circuit. of water.
  • the Applicant has overcome a prejudice which prevented it from equipping known irons with a spray nozzle, comprising a so-called “forced” water circulation pump such as an electromagnetic or peristaltic pump.
  • a so-called "forced” water circulation pump such as an electromagnetic or peristaltic pump.
  • the piston spray pump cannot create sufficient vacuum in the line 14 to, at the same time, actuate the valves of the "forced” water circulation pump and overcome the pressure drop of the cassette. demineralization to pump water from the tank.
  • the vaporization pump 24 by repeated action on the piston 24 ', easily draws water from the reservoir 5 through the cassette 15 and the clearance e existing between the casing 10 and the member 11 of the pump 9.
  • the cassette 13 due to its arrangement, makes it possible to reduce the pressure of the water in the pipeline and to obtain a particularly advantageous and effective regulation of the water flow rate for adjusting the flow rate d in the steam generator at the level of the small chamber 16 and of the needle 18.
  • the water pipe 14 connected to the steam generator 4 comprises a valve. 30, the opening of which authorizes the passage of water is controlled by a thermal element 31 such as a bimetallic strip in connection with the heating sole 2. Thus this thermal element releases the passage of water only when the iron is hot.
