Definitions

  • the present invention relates to a dynamic flow washing machine, that is a washing machine in which the washing liquid has variable characteristics of temperature and concentration of detergent during the washing operation to allow the maximum efficiency with the minimum consumption of energy, water and detergent.
  • washing machines known on the market in which, after a cold liquid-detergent solution has partially filled a washing vessel, this is heated, withdrawn from the bottom of the vessel and returned as a shower into the washing vessel.
  • German Patent Application DE-O-1610190 It is also known from German Patent Application DE-O-1610190 that a similar recirculation system can be used to convey the liquid, already introduced into the vessel, to a detergent container to remove it therefrom and introduce it into the washing vessel.
  • diffusers are then introduced into the washing vessel together with the items of clothing to be washed, and reliance is placed on these diffusers to obtain a gradual release of the detergent, from which there is thus a gradual increase in the concentration as the washing operation proceeds, so as to ensure functional efficiency.
  • the washing cycle can be interrupted, the washing machine emptied of its liquid content, and a new washing cycle started manually, (with the introduction of new detergent) similar to the automatic prewashing, bleaching and rinsing cycles already known and used in the art.
  • This operation requires the user to be present during the operation of the washing machine in order to activate a repetition of the washing cycle with inevitable great consumption of water and energy for reheating the volume of water again.
  • the initial concentration can be limited to the optimum value for commencing the wash without waste of detergent, formation of lumps and sediments, even with detergent having a compact formulation, the concentration being restored during the course of the same washing operation in one or more stages at rigorously controlled times.
  • the recirculation flow is used not only for renewing the concentration of detergent, but also for the rinsing operations which are thereby made more efficient, and for taking in, preferably hot, bleach and additives the action of which is increased.
  • the recirculation flow is returned into the washing vessel by means of a spray nozzle preceded by a syphon with a piezometric loading column which ensures a forceful outflow.
  • a twin parallel recirculation circuit for dividing the flow which passes through the detergent container and exploiting the delivery head of the pump for actuation of a water extractor which intensifies the jet action of the flow coming from the detergent container, making the adoption of the loading column superfluous and causes any possible lumps of detergent to be broken up making it easier for them to be dispersed and dissolved.
  • a twin parallel recirculation circuit for dividing the flow which passes through the detergent container, exploiting a second flow duct directed within the washing vessel and utilising the whole delivery head of the pump.
  • the preceding characteristics are combined with the use of a single pump for recirculation of the fluid and for emptying, and a flow diverter device for diverting the flow towards the recirculation and towards the drain outlet, downstream from the pump and upstream from the orientable nozzle.
  • the preceding characteristics are combined with the adoption of a double orientable nozzle, or double capture nozzle, which allows the washing machine to operate both in a conventional manner, without recirculation, and with dynamic flow recirculation at the choice of the user, by pressing a simple selection key, in such a way as to satisfy the most varied requirements of the user with automatic washing techniques from simple soaking in a static bath, to washing by agitation, to washing with a recirculation flow and spray whether or not combined with mechanical agitation, according to the various requirements of the fabrics.
  • the machine comprises a washing vessel 7 of conventional type, in which is mounted a rotating drum 8 driven by a motor not shown.
  • the vessel is closed at the front by a resilient seal 9 joined to a front loading door.
  • heating elements 10, 11 In the lower part of the vessel are housed heating elements 10, 11.
  • a suction duct 12 connects the vessel to the input of a pump 13 fitted with a filter, the output of which pump is selectively connected via a flow diverter 14 to a drain pipe 15 or a recirculation pipe 16.
  • a separate drain pump could be used with an input connected to the vessel and a delivery connected to the drain pipe 15.
  • the recirculation pipe 16 terminates at an orientable nozzle 17 (or other equivalent flow diverter) actuated by a distribution rod 18 controlled by the rocker 19 of a cam programmer 20.
  • the nozzle 17 opens above a detergent container 21 having several compartments 1, 2, 3, 4, 5 which nozzle, as already mentioned, can be orientated selectively towards any of the compartments under the control of the programmer.
  • the container 21 is housed in a flow-collector box 22 which opens into a syphon 23 isolated from steam, terminating in a spray nozzle 24 orientated towards the interior of the washing drum 8 through the resilient seal 9.
  • the nozzle is provided with a piezometric column 25 disposed downstream of the syphon 23 and open into the vessel 7 with an overflow opening.
  • a water inlet duct 26 connected to the water mains via a control valve 27 opens via a nozzle 28 into a region 7 of the flow collector box 22, leading directly to the syphon 23.
  • FIG. 1 schematically illustrates in greater detail the cam programming device of Figure 1.
  • the device essentially comprises a cam 20 with a step profile having several levels, identified in the drawings as L6, L1, L2, L3, L4, L5 cooperating with a rocker 19 provided with a cam follower roller 29.
  • the cam 20 is coupled to a shaft 30 of a programmer 301 of known structure, having teeth 31 and 32 which allow free clockwise rotation of the cam 20 by means of the action of a knob 33 connected to the cam.
  • the cam is rotated in a clockwise direction by a drive shaft 30, driven by a geared motor 47 and controlled by a step-by-step timing escapement and the program set on the cams (of which only the cams 305, 306 are shown) read by the electric circuit.
  • the cams via the knob 33, are set in a starting position by the user who can chose from a plurality of working cycles by moving a predetermined sector of the knob 33 into correspondence with a fixed reference index. With this movement a predetermined sector of the cam 20, indicated for example by the arrow 34, is brought into correspondence with the roller 29.
  • the different levels of the cams define different working conditions of the control switches of the programming system (cams 305, 306) and different orientations of the nozzle 17 of Figure 1 (cam 20).
  • the working conditions progress gradually as the cams rotate and the different levels of the cams 20 are disposed under the roller 29.
  • the levels L4, L5 define active conditions of the rinsing steps, with possible operation of the pump 13.
  • the level L6 defines a pre-filling condition.
  • Figure 3 is a simplified circuit diagram illustrating the control and actuation system for the washing machine of Figure 1.
  • a main operating switch 35 manually controlled by a bistable push button, connects and isolates the system from the main voltage.
  • the terminal 139 of the pressure switch 36 closes on the terminal 138 when the washing vessel is empty, and commutes to the terminal 40 when the liquid in the vessel reaches a pre-determined level (indicated N in Figure 1).
  • the switch 37 which is normally open, is closed by control from the programmer (cams 305, 306) when the active profile of the cam 20 corresponds to predetermined levels, indicated in brackets, next to the switch, although not necessarily in synchronism with the activation/disactivation of the levels.
  • Switch 38 when closed, and on the condition that the washing vessel is filled with a sufficient quantity of water (pressure switch 36 activated) activates a heating element 10.
  • switch 39 which activates a heating element 11 if the further condition is satisfied that a bistable economy switch or temperature limitation switch 44, which is normally closed, is actuated to open.
  • the switch 40 when closed, activates the emp- tying/recirculation pump 13 and the switch 41, when closed, commutes the flow diverter 14, which is normally open to the drain, towards the recirculation pipe 16.
  • the switch 42 when closed, activates the motor 46 for slow intermittent bi-directional rotation of the drum 8.
  • the switch 43 when closed, activates a spin- drying operation by acting on the circuits MC of a motor 46.
  • the normally closed switch 45 disac- tivates the geared motor 47 for driving the programmer and the cam 20 at the end of a working cycle.
  • the first qualitative diagram 48 indicates the effective concentration of detergent in the washing liquid.
  • effective concentration is intended here and hereinafter the ratio by weight between the detergent fraction which has not lost its detergent power by agglomeration, sedimentation or aggregation and combination with particles of dirt, and the weight or volume of liquid in which this fraction is dispersed or dissolved.
  • the second diagram 49 describes the temperature variations in the wash water.
  • LEV is indicated the level of liquid in the washing vessel, namely N (normal) at the end of filling, B (low) by the effect of rotation of the drum and soaking up by the fabrics, R (reduced) by the effect of activation of the recirculation pump, or 0 (empty).
  • the numerals 1, 2, 3, in line DET indicate, from which compartment the detergent is to be taken, or (by numeral 6) that the collection vessel is to receive water direct.
  • the valve 27 is open and starts filling with cold water which sprays, through the nozzle 24, onto the washing in the drum 8 until reaching a first wash level N. Subsequently the drum will be rotated slowly.
  • the diverter 14 is also activated.
  • the detergent solution is introduced through the nozzle 24 into the washing drum. At this stage the level of wash water in the vessel falls somewhat and is indicated in Figure 1 by level R.
  • the detergent carried away by the hot liquid, rapidly dissolves with a reduced formation of lumps, and the effective concentration of detergent increases rapidly up to the optimum value, thereby developing its best action on the fabrics to be washed.
  • a first dynamic washing stage has thus started in which the detergent bath in continually recirculated to ensure that the whole of the detergent is removed from the compartment 1 and continuously sprayed onto the fabrics to be washed via the nozzle 24.
  • the wash temperature can be gradually increased (diagram 49) or, if the temperature limitation function has been set, the heating can be interrupted and the temperature can be allowed to fall naturally as shown in the diagram by the broken line 50.
  • heating of the wash liquid is preferably interrupted, if not already interrupted before by the economiser control, in preparation for the following wash liquid emptying and subsequent spin drying and rinsing operations.
  • a dynamic flow washing operation is thus achieved, constituted by a first stage and second or subsequent stages (two in Figure 4) during the course of which the effective concentration of the detergent is restored, always being taken by hot liquid and therefore being more easily dissolved, without interruption of the washing cycle by liquid emptying, refilling and reheating stages. It is only at the end of these stages that the washing vessel is emptied.
  • the effectiveness of the wash is further increased by the direct spraying of the fabrics to be washed through the nozzle 24, preceded by a syphon 23, isolated from steam, with the piezoelectric loading column 25 which ensures a head H ( Figure 1) and therefore a predetermined outflow speed of the jet which, with its dynamic action, exerts a further breaking up of the dirt and penetration of the wash liquid into the fibres of the fabric.
  • the loading column also ensures an adequate outflow pressure at the nozzle to prevent clogging and, in the improbable case of blockage, guarantees overflow into the vessel from the top.
  • the head H cannot exceed the limits allowed by the normal dimensions of the washing machine and is therefore kept between 25 and 40 cm.
  • the speed of outflow of the jet is increased by wholly or partly exploiting the delivery head of the pump 13.
  • Figure 5 schematically represents the relevant details of this improvement: upstream of the nozzle 17 where the lose of static head produced by the pump 13 predominantly takes place, the recirculation pipe 16 has a branch 51 which terminates in a nozzle 52 within the nozzle 24 and orientated towards the outflow opening of this latter.
  • the recirculation flow is therefore divided: a suitable fraction is utilised for taking up detergent to be introduced at ambient pressure into the syphon 23; the residual fraction, at the pressure set by the delivery head of the pump, is used to obtain at the outlet of the nozzle 52 a high speed jet which dynamically urges the solution present in the syphon 23 towards the outlet of the nozzle 24 thereby causing, among other things, the fragmentation and dissolution of possible lumps of detergent present therein.
  • the effectiveness of the washing jet from the nozzle 24 is increased not by an increase in its speed, but by interference with a second transverse spray jet obtained, as illustrated in Figure 6, by dividing the recirculation flow: upstream of the nozzle 17 the recirculation pipe 16 has a branch 61 which ends in a nozzle 62 orientated towards the filling opening of the drum 8.
  • the recirculation flow is thus divided: suitable fraction is utilised to remove the detergent and is introduced under ambient pressure into the syphon 23; the residual fraction, at the pressure set by the delivery head of the pump, is used to obtain at the output of the nozzle 62 a high velocity jet cooperating in the washing action with the output flow from the nozzle 24.
  • the washing machine described is improved by being able to operate in a wide range of different modes comprising at least one "conventional” washing mode with simple agitation and the "dynamic flow” washing mode with recirculation and restoration of the effective detergent concentration.
  • FIGS 7 and 8 illustrate modified embodiments which allow this dual function.
  • the flow is diverted by the guide 54 into the associated detergent compartment 21, which is sprayed with liquid which, by overflowing (or filtering) into the box 22 and the syphon 23, conveys the detergent with it.
  • the nozzle 17 is provided with an additional guide duct 55 open to the water fill duct 28 and provided with an outflow opening 56 disposed above the opening 53 and orientated in the same direction.
  • the nozzle 17 constitutes a double nozzle which can take detergent from any of the compartments with a jet obtained from the filling duct or from the recirculation duct according to which of the two streams is activated.
  • FIG 8 repeats in partial form the control diagram of Figure 3 with modifications introduced to allow the multifunctions described.
  • the heating element 10 is activated by closure of the switch 38 (as in Figure 3) and also by closure of a switch 56, in series with a normally closed switch 57, and actuated by a bistable control push button LD which selects the dynamic washing mode as an alternative to a normal mode.
  • the pump 13 is activated by closure of the switch 40, in series with a normally open switch 58 actuated by the bistable push button LD.
  • the pump 13 is then activated by closure of a switch 59 during the course of the emptying and spin drying stages.
  • the fill valve 27 is enabled by the switch 37 during the stage characterised by the active profile of cam L6 only if consent given by closure of the switch 60 (actuated by push button LD) is present.
  • the fill valve 27 is enabled by the switch 61 (closed by the active cam profile at level L1).
  • activation of a washing cycle does not cause any operation during the time interval in which the active cam profile is at level L6.
  • the detergent compartment must be so dimensioned as to contain an adequate quantity of detergent, corresponding to the requirements of washing machines which use conventional washing cycles.
  • the machine forming the subject of the present invention may operate a double detergent withdrawal in two successive steps from two different compartments, which requires a further filling with water, with consequent further availability of energy for heating.
  • the water level in the vessel can now reach a height C2.
  • the machine forming the subject of the present invention is able to contribute in a substantially more effective manner to the performance of these operations.
  • instant T6 represents the commencement of a rinsing stage.
  • the diagram shows that the rinsing can be performed not only by the effect of slow rotation of the drum, but also by the effect of a continuous spraying by the recirculation flow (dynamic rinsing: interval T7-T8).
  • the diagram of Figure 4 also shows, after a rinsing cycle, the execution of a bleaching cycle at (high) temperature.
  • the liquid infill can be effected (interval Tl 0-Tl 1) before taking the bleach, from a compartment indicated with reference numeral 5, due to the recirculation flow and before heating of the pre-fill water (interval T11-T12) to make the dynamic bleaching action more effective (Interval T12-T13), followed by emptying and conventional spin drying (intervals T13-T14-T15).
  • the temperature of operation of the heating elements can be controlled by thermostats, and the number of times the effective concentration is restored can be different from two.
  • the nozzle 17 for directing the recirculation flow onto the detergent container can also be replaced by any functionally equivalent element, such as a two-way diverter or a plurality of solenoid valves, even though the nozzle is preferred because of its simplicity and effectiveness.
  • the presence of the double nozzle such as that shown in Figure 7, or of equivalent devices in as much as they are preferable for achievement of the multifunctionality already described, is not indispensable: in fact, it is sufficient that the washing machine fill nozzle 28 be positioned on a first compartment of the detergent container to allow filling of the washing machine and simultaneous withdrawal of a first quantity of detergent.
