Definitions

  • the present invention refers to a device for intercepting the flow of a fluid that passes through a distributing circuit, in particular for washing machines.
  • dishwashers for household usage comprise a box-shaped structure defining a washing chamber that houses an upper loading basket and a lower loading basket, being intended for containing the items to be washed.
  • a sprayer is positioned under each loading basket which, by rotating around a substantially vertical axis, hits the dishes placed in the basket with a plurality of washing liquid jets; to this purpose, a special motor-driven recirculation pump conveys the liquid under pressure to the sprayers.
  • the hydraulic circuit of the dishwasher is obtained in such a way to execute a washing cycle by feeding a single sprayer, or by feeding both sprayers alternately.
  • the first solution is typical of cases in which the dishwasher must be able to carry out a so-called "reduced” washing program, i.e. when only one of the basket is used to contain the dishes, and only the sprayer that corresponds to the used basket must be fed with the washing liquid.
  • a device can be provided for a continuous interception of the liquid flow coming from the recirculation pump to one of the two feeding branches of the sprayers; the intercepting device, being duly controlled by the machine control system, keeps one of the two branches of the hydraulic circuit closed, in such a way as to feed with the liquid, throughout the washing program, only the sprayer related to the used basket.
  • an intercepting device is instead provided for directing alternately the liquid in one of the two branches mentioned above; in other words, the control system of the machine controls the intercepting device in such a way that the latter opens and closes alternately the two branches of the hydraulic circuit, in such a way that the washing cycle is obtained by feeding alternately the upper and lower sprayer.
  • a same intercepting device can execute both of the above-mentioned functions, i.e. continuous closing on one of the two circuit branches, in order to carry out a "reduced" washing program, and flow deviation in the two branches, in order to carry out a washing with alternate feeding of the sprayers.
  • an intercepting device used to obtain an alternate washing comprises substantially a movable flap or plug, placed in correspondence of the point where the two above-mentioned branches of the hydraulic circuit depart; said plug can assume at least a first operating condition, characterised by the opening of the branch that feeds the upper sprayer and by the closing of the branch that feeds the lower sprayer, and a second operating condition, opposed to the previous one.
  • the movement of the above-mentioned plug from one position to the other is obtained by means of a electric-thermal actuator.
  • the actuators of the thermal type are well known and do not need an in-depth description here (see for example EP-A-940 577). It is enough to specify here that these actuators comprise usually a body containing a thermoexpansible material and, at least partially, a piston; a heater is associated to the mentioned body, like a resistor with a positive temperature coefficient, or PTC.
  • the piston can therefore retract towards the inside of the body, upon the action of an elastic element, like a spring, and in this way switch back the plug of the flow intercepting device from the second to the first operating condition.
  • the first drawback derives from the fact that the control system of the dishwasher, whether electromechanical or electronic, presumes a certain complexity to obtain the required feeding cycles of the thermoactuator.
  • Another drawback of the mentioned solution derives from the fact that the operating times of a thermal actuator are relatively long, since the movements obtained from it are linked to the heating and cooling phenomena of a thermoexpansible material.
  • a drawback connected to the previous one consists of the fact that the operating times of a thermal actuator are different in the two operating stages; in other words, the time required to produce the heating of the thermoexpansible material and the ensuing exit movement of the piston from the actuator's body is different from the time required to obtain the cooling of the same material, and the ensuing backing of the piston.
  • a double winding motor is provided, instead of a thermal actuator.
  • the motor is initially operated with a first direction of rotation, by energising its first winding, to move the shutter from its first to its second working position; then, the direction of rotation of the motor is inverted, energising its second winding, in order to return the shutter to its initial position.
  • the supply of the mentioned double winding is time-controlled, i.e. it is supplied for a fixed period being considered sufficient to determine the passage of the shutter from one working position to the other.
  • the calibration or adjustment of the diverting device can be compromised; for example, this is due to the fact that some plastic parts of the intercepting device are exposed to continuous thermal stresses, and hence potentially subject to variations in size.
  • the time set for the motor supply may result longer or shorter of the one strictly required to obtain a correct positioning of the shutter, with ensuing operating extrastrokes or efforts, which can break the intercepting device or cause the failure of its motor, or make it impossible to reach the correct working position of the shutter.
  • the present invention has the aim of solving the above drawbacks of the prior art.
  • the aim of the invention is to indicate a device for intercepting the flow of a fluid, in particular for washing machines, being of simple design and manufacturing, being highly reliable in time and being of low cost.
  • Fig. 1 shows a schematic representation of a dishwasher using an intercepting device obtained according to the principles of the present invention.
  • 1 indicates the washing chamber of the machine, comprising a lower collecting sump, indicated with 2; 3 indicates a washing or recirculation pump, equipped with an electric motor.
  • 3A indicates the suction branch of the mentioned pump, that draws the washing liquid from the sump 2; pump 3, by means of its delivery 3B, forces the washing liquid in a hydraulic circuit, comprising a first branch 4 feeding a lower sprayer 5, and a second branch 6 feeding an upper sprayer 7; baskets 8 and 9 are placed in a known way above of each sprayer.
  • the intercepting device 10 is capable of assuming at least two different alternative operating conditions, and in particular:
  • the intercepting device 10 which is shown in different views in Figs. 2 and 3, comprises a main body 11, for example realised in thermoplastic material, defining an inlet 12 for the connection to the delivery 3B of pump 3, and two outlets 13A and 13B for the connection to the feeding branches 4 and 6 respectively, of the lower sprayer 5 and the upper sprayer 7; the body 11 comprises an upper part 11A and a lower part 11B, coupled with known means, with a gasket placed in between, not represented in the figures.
  • a plug or shutter member 14 is placed between inlet 12 and outlets 13A and 13B; in the example, this plug is of the rotating or angular movable type.
  • An electric motor 15 is associated to the upper part of body 11, by means of screws 16 intended for being screwed in suitable seats 17 defined in the body 11.
  • Motor 15 which, if necessary, is equipped with a suitable internal gear-reducer, presents a shaft 15A that is connected to a suitable transmission element ET, made integral with plug 14 or realised as a single piece with the latter; obviously, on the upper part of body 11 a proper opening is defined, for the passage of a part of the transmission element ET, in correspondence of which proper sealing means are preferably provided.
  • AP indicates an additional member, coupled with the transmission element ET, presenting a radial projection AP'; 18A and 18B indicate two stops with which projection AP' is able to come into contact following an angular movement of the transmission element ET (see, to this purpose, also Figs. 7 and 9). It should be noticed that, in the given example, the above-mentioned stops 18A and 18B consist of projections of the upper part 11A of body 11, which are used also as supporting and positioning means for the motor 15.
  • FIGs. 4-6 some components of the intercepting device 10 according to the invention are represented in more detail.
  • plug 14 which is defined as a whole by an upper circular wall 14A and a lower circular wall 14B, joined together by means of a bent wall 14C extending for nearly half of the circumference of the said walls 14A and 14B; in other words, therefore, the plug 14 has substantially the shape of a hollow cylinder whose circumference wall lacks a portion.
  • the shape of the plug 14 may differ from the one in the example of the figure, like for example a substantially spherical shape, where a passage or a discharge having a proper shape is defined in order to allow the required hydraulic connection between the inlet 12 and the outlet 13A, and between the inlet 12 and the outlet 13B.
  • discharges or undercuts having substantially a semicircular shape are defined at the two side ends of the bent wall 14C, indicated with 14D, with dimensions being congruent to that of the outlets 13A and 13B of the device 10.
  • the transmission element ET is coupled to the upper wall 14A of the plug 14, or realised as single piece with the latter; in the lower part of the transmission element ET, i.e. the one that remains within body 11 of the intercepting device 10, are defined one or more seats ET', for the housing of an equal number of proper sealing means, like one or more o-rings, not represented.
  • the upper part of the driving element ET i.e. the one remaining outside the body 11 of the intercepting device 10, is indicated in Figs. 4-6 with ET"; at the upper end of part ET", on its external surface, a discharge or undercut 19 is defined, whose function will be explained later; part ET" is internally hollow, for defining a seat 20 able to receive the end of shaft 15A of motor 15.
  • the end portion of shaft 15A and seat 20 present congruent sections, so that the angular movement of the shaft determines a corresponding movement of the transmission element ET; for this purpose, in the example of the figure, the end of shaft 15A and seat 20 present a substantially semicircular section, or an or equivalent one; on the other hand, it is clear that such a section can have any other shape proper for the object, like for example a square or hexagonal shape.
  • the additional member AP presents a housing (not visible in the figures) in its lower part, being able to receive and couple with the upper end of part ET" of the or transmission element ET, where the mentioned discharge or undercut 19 is defined.
  • the upper end of part ET" and the mentioned housing of the member AP are designed in such a way that the angular movement of the transmission element ET determines a corresponding movement of the member AP and of the relative radial projection AP'.
  • the central passage of member AP can advantageously present a section congruent to that of seat 20 and to the end portion of shaft 15A (as said, in. the example of Fig. 4, this section has a substantially semicircular shape).
  • motor 15 is a single-phase synchronous motor, having a single winding and a permanent magnet rotor.
  • this kind of motor has no preferred starting direction, i.e. its rotor is able to start and rotate in both directions (clockwise and counter-clockwise) indifferently. It also known that, if during the angular movement in one direction, the rotor is subject to a braking moment or is exposed to a thrust in the opposite direction, the mentioned type of motor reaches a stall condition, which is automatically followed by a reversal of the direction of angular movement of the rotor, due to electromagnetic effect. It is also known that the rotor or the shaft of the mentioned type of motors has a substantially fixed revolution speed, which depends on the mains frequency, on the motor's specifications (for example the number of poles) and on the possible presence of a gear reducer.
  • the stops 18A and 18B are provided, with which projection AP' comes into contact alternately, according to the direction of clockwise or counter-clockwise rotation of the motor; as it can be imagined, in this way, plug 14 can be moved by the transmission element 14A in opposite directions, in order to open and close alternately, and with equal times, the outlets 13A and 13B of the intercepting device 11.
  • the end of projection AP' intended to come into contact with the stops 18A and 18B is equipped with elastic elements, such as a rubber covering, in order to create a bouncing effect, i.e. for contributing to give projection AP', as well as element ET and shaft 15A, an angular movement having a direction being opposite to that of impact on one of the stops.
  • elastic elements such as a rubber covering
  • the elastic elements can be provided on stops 18A and 18B, instead of on projection AP', or the same projection AP' can be shaped for giving the latter a certain elasticity that is useful for the purpose.
  • the dishwasher equipped with the intercepting device according to the present invention works as follows.
  • control system of the machine controls the execution of the washing cycle, including its usual phases, like for example one or more prewash phases, one or more washing phases, one or more rinsing phases, according to the technique of supply alternation the sprayers.
  • each phase of the cycle starts by loading in tank 1 the required water quantity, measured with known modalities (for example by means of a pressure switch). Therefore, once the quantity of water required by the first prewash phase has been loaded from the external water mains, the control system controls the activation of the recirculation pump 3 by supplying the motor of the latter.
  • motor 15 has no preferred starting direction, but as it can be imagined, this is practically irrelevant in view of the proper and efficient operation of the dishwasher; the position of plug 14 before starting motor 15 is practically irrelevant, too.
  • the motor 15 will be realised with known modalities in order to obtain a proper speed of shaft 15A, which determines the desired switching speed of plug 14 from one working position to the other; these speed values depend on the mains frequency as well as on the motor specifications (for example, on the number of its poles) and/or on the possible presence of a gear reducer; for what concerns this aspect, it should be pointed out that the prevision of a proper gear reducer realised as known, seems to be preferable, in order to have a small motor 15, whose shaft 15A is anyway able to produce high forces or torques, being adequate to the purpose.
  • motor 15 can be connected electrically in parallel with respect to the motor of pump 3, in such a way as to ensure a simultaneous supply, and therefore a simultaneous operation of device 10 and of the said pump 3.
  • an intercepting device for a flow of a fluid that passes through a distributing circuit (branches 4 and 6), in particular of a washing machine;
  • the device (10) comprises an actuator (motor 15) presenting a displacement part (shaft 15A) that can work in two opposite directions, said displacement part being able to displace a plug (14) which can move until it reaches at least a respective first working position.
  • the intercepting device (10) comprises striker means (member AP and corresponding radial projection AP') that follow the movement of plug (14) and are capable of come into contact with respective fixed stopping surfaces (stops 18A and 18B), where the contact of the strikers with a first of the stopping surfaces corresponds to the attainment, by plug (14), of the said first working position.
  • the actuator (15) under constancy of electric supply to the actuator (15), the latter is capable of inverting the direction of movement of the displacement part (15A) automatically, following the effect (in particular a mechanical one) that the contact of the striker means (AP,AP') with one of the stopping surfaces (18A,18B) determines on the displacement part (15A).
  • the plug (14) is capable of reaching at least a second working position, where the contact of the striker means (AP,AP') with a second one of the stopping surfaces corresponds to the attainment, by plug (14), of said second working position.
  • the plug (14) is continuously moved in opposite directions, in order to pass in an alternate way between the said first and the said second working position.
  • the actuator comprises at least one single-phase synchronous motor, in particular having a single winding and a permanent magnet rotor, and the speed of the displacement part is determined by the mains frequency and/or by a gear reducer.
  • the invention has a specially advantageous application in the field of dishwashers, for the realisation of washing cycles with alternate supply of the sprayers; however, it is clear that the described device can be applied also on other kinds of washing machines for household usage, like for example laundry washers and/or washer-dryers, and on other devices and systems where it is useful or necessary to realise a cyclical deviation or interruption of the flow of a fluid, whether liquid or aeriform.
  • the device according to the invention must not be perceived as applicable exclusively to cases in which a first duct must be completely closed in favour of another one, but can be provided instead for partializing or adjust the flow-rate of the fluid which has to be cyclically fed to the two ducts.
  • plug 14 and the two end-of-stoke positions of the latter can be chosen in order to obtain only a suitable narrowing or throttling of the distributing circuit, between the inlet 12 and the outlet 13A on one side, and between the inlet 12 and the outlet 13B on the other side.
  • This variant can be applied when the two branches of the distributing circuit of the fluid that depart from the outlets of the device according to the invention must be fed substantially in an alternate way with different liquid flow rates, for example in order to obtain a wash with different washing pressures for sprayers 5 and 7, if the dishes contained in basket 9 are more fragile than those in basket 5.
  • intercepting device and "plug member” used here must be intended in their more general meaning, i.e. indicating respectively a device that allows also the partial closure of a duct, and a member that allows to adjust the flow rate of a fluid.
  • each stop can consist of the end of a threaded element, being screwed in a respective seat that extends substantially perpendicularly to the shaft 15, said seat being defined in a proper support that raises from the upper surface of body 11.
  • the device for intercepting the flow of a fluid according to the present invention resulted in resolving efficiently the previously mentioned typical problems of the prior art.
  • the device for intercepting the flow of a fluid according to the present invention resulted in resolving efficiently the previously mentioned typical problems of the prior art.
  • a magnetic element can be associated to projection AP' and a proper known position switch or sensor (for example a reed sensor or a Hall effect sensor) can be associated to the intercepting device 10; in this case, the position switch or sensor shall be properly connected to the control system of the machine, and calibrated for detecting the attainment, by the projection AP', of the contact position on one of the two stops, like for example the stop 18A.
  • a proper known position switch or sensor for example a reed sensor or a Hall effect sensor
  • the operation of the dishwasher according to the proposed variant is the following.
  • the user loads the dishes in the basket set for the execution of the reduced washing cycle (indicated on the machine's handbook), which in the example is the upper basket 9.
  • the first phase starts with the corresponding loading in tank 1 of the required water quantity.
  • the control system of the machine checks, by means of the mentioned position switch or sensor, if the projection AP' and plug 14 are in the correct closing position of the outlet 13A and opening of the outlet 13B of the intercepting device 10.
  • control system of the machine enables the power supply of motor 15, until the switch or sensor detects that the above-mentioned correct position has been reached (notice that, in compliance with this variant, the device 10 can be provided with an electric supply being independent from that of pump 3, so that the motor of the first one and of the second one can be driven by the machine control system also at different moments).
  • control system controls the activation of the recirculation pump 3, by supplying the motor of the latter.
  • intercepting device 15 is maintained throughout the following phases of the washing cycle, i.e. without the need to carry out further positioning controls of plug 14.
  • the intercepting device 10 can also be used to execute a reduced washing cycle, with a given basket of the machine (i.e., in the example, the upper basket 9).
  • a washing machine using the fluid intercepting device according to the present invention can be easily prearranged in order to offer the user the possibility to select the basket to be used in order to execute the reduced washing cycle.

  • the senor/s provided may be provided for detecting directly the position of plug 14, and not indirectly by means of the projection AP'; in this case, the magnetic element mentioned previously shall be associated directly to the plug 14.
  • Appendix AP' can be integral with the shaft 15A of motor 15, rather than with the transmission element ET; likewise, the same projection AP' can be replaced by at least a projection or a part of the plug 14, and the stops 18A and 18B can be replaced by proper end-of-stroke means being defined within the body 11.
