Definitions

  • the present invention refers to the water-conducting electric household appliances in general, such as dishwashers and laundry washing machines, and has been developed with particular reference to the methods for the loading of water in such appliances.
  • Water-conducting electric appliances such as dishwashers and laundry washing machines have a treatment container, designed to receive items to be washed.
  • a treatment program of such household appliance comprises a plurality of operating steps, at least some of which performed with water, such as steps of pre-washing, washing, rinsing, soaking. Each of these steps involves the loading of water into the treatment container, the execution of a respective part of the treatment and then the drain of the used liquid.
  • the control system controls the execution of one or more re-fillings, during a same program step.
  • the water is usually drawn from the domestic water supply and its volume is dosed with a filling sensor, typically a sensor of a pneumatic type (such as a pressure switch), a sensor of a volumetric type (such as a flow meter with impeller) or a sensor of an optical (such as a device including a light emitter and a light receiver).
  • a filling sensor typically a sensor of a pneumatic type (such as a pressure switch), a sensor of a volumetric type (such as a flow meter with impeller) or a sensor of an optical (such as a device including a light emitter and a light receiver).
  • EP 2276388 A discloses a method to control the filling up of a water-conducting electric appliance, according to which the possible condition of a total failure of a filling sensor is detected by using a washing pump and evaluating the flow-rate characteristic curve of the pump.
  • the present invention aims to obtain a method alternative to the one known from EP 2276388 A , to be used in case of absence of signal from a sensor arranged to detect the loading of water into the treatment container, which is however simpler and more quick to intervene.
  • One auxiliary aim of the invention is to provide a method which allows controlling the filling with water of a water-conducting household electric appliance even in presence of anomalous signals from a sensor of the aforementioned type.
  • the appliance according to the invention comprises all the elements in itself known for its operation, such a possible external cabinet thereof, a user interface, a resistance for water heating, a dispenser of washing agents, and so on.
  • figure 1 is schematically represented a water-conducting household electric appliance according to a possible embodiment of the present invention, here represented by a domestic dishwasher, illustrated limited to the parts of immediate interest for the understanding of the present invention.
  • the machine 1 has a structure 2 that comprises a treatment container 3, here represented by a wash tub, having below a housing space in which various functional components of the machine 1 are positioned, among which a pump 4 and a sump 5 for water collection, as well as other components not shown in the figure for reasons of greater clarity of the drawing.
  • the wash tub 3, of a conception known as a whole, comprises an upper wall, a lower wall and four side walls one of which - the front wall - consists of the inner shell of the door of the machine, not shown here (the so-called "counter door ").
  • the machine 1 has a lower basket 6 and an upper basket 7, designed to contain respective loads of crockery.
  • the machine 1 has a spraying system, which includes at least one sprinkler member to sprinkle with water the crockery contained in a basket.
  • the spraying system includes two sprinkler members 8 and 9, to sprinkle with water the crockery contained in the baskets 6 and 7, respectively.
  • the spraying system is fed through the wash pump 4 and through a known device 10 for the alternating supply of the sprinklers 8 and 9; the device 10 has at least one inlet, connected to the delivery of the pump 4, and at least two outlets, connected via ducts 10a and 10b to the sprinklers 8 and 9, respectively.
  • the machine 1 has a supply duct 11, for connection to a domestic water supply mains, on which is a controllable loading valve 12, for example a solenoid valve.
  • the machine also comprises a sensor device, also defined in the following, as filling sensor, prearranged for detecting conveying of water, from the water supply mains, in the tub 3, i.e., for generating signals representative of a level of the supplied water level or of its volume.
  • the aforesaid sensor device is a volumetric sensor with an impeller, designated by 13. Sensors of this type are well known in the field. Reference can be made, for example, to EP 0599341 for the description of a flow meter of this type, suitable for the purposes of use on the machine 1.
  • such a sensor includes an impeller set in rotation by the fluid, such impeller integrating or having associated one or more excitation elements; a stationary part of the sensor then includes a detector, suitable to be excited by the excitation elements movable with the impeller.
  • the excitation element or elements can be of a magnetic type, in which case the detector is a magnetic field detector; alternatively, the detection of the rotation of the impeller can be performed via an optical detector, in which case a part of the same impeller obtains the excitation means.
  • a fluid entering the sensor device causes a rotation of the, and the number of revolutions of the latter - which is proportional to the volume on inlet - is detected by means of the aforesaid sensor.
  • the impeller-type filling sensor 13 is operatively arranged between the duct 11 and a duct 14 for feeding water into the tub 3.
  • reference 15 designates a visual signalling device, such as a light or a display set on a control panel of the machine.
  • 16 indicates an acoustical signal device, such as a buzzer.
  • 17 is indicated the control system of the machine, preferably including a microprocessor control unit associated to which are memory means containing program information and data for the execution of a plurality of possible treatment programs of the machine 1.
  • the control system 17 also includes means for the selection and the start of the aforesaid programs, not represented.
  • a user - after having loaded the crockery in the tub 3 of the machine 1 - selects a desired treatment program and causes the start thereof, for example by pushing a suitable button.
  • the system 17 controls opening of the valve 12, which is kept open as long as the system itself does not detect, by means of the filling sensor 13, the loading in the wash tub 3 of a determined volume of liquid.
  • the control system 17 - after any possible required switching of the device 10 - controls the start of operation of the wash pump 4.
  • the water loaded in the washtub reaches one or both of the sprinkler members 8, 9 and is sprinkled on the content of the baskets 6, 7.
  • the control system stops the operation of the wash pump 4 and starts the operation of a drain pump, not shown. Once draining off of the previously used water, the drain pump is stopped and the system 17 controls a new opening of the valve 12, to load the volume of water required for the execution of a subsequent step of the program treatment.
  • control system 17 monitors a return signal from the filling sensor 13 and uses such signal in order to control closing of the valve 12.
  • the control system 17 activates a signalling, by means of at least one of the visual signalling device 15 and the acoustic signalling device 16.
  • the visual signalling and the acoustic signalling are both activated. In this way, the user is immediately warned of a possible breakdown of the machine 1 due to a failure of its filling sensor 13 or to an anomalous condition of the water mains, such as the closing of a tap of the water fitting for connecting the machine or the absence of water in the mains.
  • the aforesaid first time interval has preferably a relatively short predetermined duration, indicatively not greater than one minute and preferably comprised between 10 and 30 seconds, more preferably of about 15 seconds.
  • the first load of water in a treatment program typically happens a few seconds after the start of the program itself: therefore, in accordance with a preferred embodiment of the invention, the warning concerning the anomalous condition occurs in any case after a relatively short time after the start of the program, when the user is presumably still nearby the machine 1.
  • control system 17 controls ending of the treatment program.
  • the second time interval has a predetermined duration which is greater than the first time interval, indicatively not greater than five minutes, preferably comprised between 200 and 250 seconds, most preferably about 220 seconds.
  • the control system 17 since having started the signalling of the anomaly, the control system 17 remains in a waiting condition for a given period, and continues to monitor the condition of the filling sensor 13: if during this period - the aforesaid second time interval - there occurs the signal from the sensor 13, the treatment program can continue in the usual way; one such case may happen, for example, if the tap of the connection fitting of the machine 1, which was initially, closed, is opened by the user after the start of the visual and /or acoustic signalling.
  • the program is stopped by the control system 17, which sets itself in a state of quiescence.
  • stopping of the program involves the closing of the loading valve 12.
  • the stopping of the program also implies deactivation of the signalling means 15, 16: in a preferred embodiment, however, before stopping the program, the control system 17 generates an error code that is in any case visually and/or acoustically highlighted on occasion of a subsequent use of the machine.
  • the program is anyway stopped, if the absence of signal from the sensor 13 persists.
  • the absence of the signal from the sensor 13 may be possibly remedied during the second time interval.
  • this can be the case - already mentioned - of an initially closed tap of the fitting for connection to the water mains, or the case of a momentary jamming of the impeller of the sensor, due to any reasons.
  • the absence of signal that persists throughout the whole second time interval is instead indicative of circumstances such as a total absence of water in the water mains, or else of a failure of the sensor 13 so serious that emission of any signal is impeded, or still the accidental disconnection of the sensor 13 from a connector thereof.
  • the filling sensor 13 generates a signal, but this signal is not readable or usable in an effective way by the control system 17 for the purposes of the dosage of the volume of water necessary for the operation of the machine.
  • the number of output signal pulses is substantially proportional to the volume of water that passes through the sensor itself.
  • the number of pulses generated by the sensor in a unit of time is comprised on average in a range or determined range of values, which can be stored in the control system 17 (note that often the electrovalves for water loading used in the household electric appliances or the same impeller meter include a flow or pressure regulator, also having the function to make the water flow-rate stable; see for example EP 1456576 A ).
  • the number of pulses in the time unit does not fall within the aforesaid range: think, for example, to a sensor 13 whose impeller - due to a damage of rotation pin or of the supports of the latter - rotates slowly and in a jerky way or on the contrary rotates too quickly, or to a fault of the detector of the rotation of the impeller.
  • the control system 17 in presence of one such "anomalous" signal from the sensor 13 - i.e., a signal which is not compatible with a stored reference value or range of values, or anyway incomprehensible or not effectively usable by the system 17 to determine the volume of water that is being loaded in the tub - the control system 17 keeps the loading valve 12 open until elapsing of a predetermined time interval , hereinafter referred to also as third time interval for simplicity, for example comprised between 40 and 80 seconds , preferably about 60 seconds.
  • a predetermined time interval hereinafter referred to also as third time interval for simplicity, for example comprised between 40 and 80 seconds , preferably about 60 seconds.
  • the control system 17 controls the closing of the loading valve 12 and drives the motor of a treatment pump 4 to a first predetermined speed, preferably a speed lower than the normal washing speed.
  • a first predetermined speed preferably a speed lower than the normal washing speed.
  • the control system 17 monitors a signal characteristic of the operation of the motor of the pump 4 and evaluates this signal, by comparing it with a first threshold value. If the characteristic signal does not reach and/or does not exceed the first threshold value, the control system 17 controls a new opening of the valve 12 and then evaluates again the signal characteristic of the operation of the motor of the pump 4: when this characteristic signal reaches the first threshold value, the control system 17 control closing of the valve 12.
  • the aforesaid characteristic signal can be for example the amount of current absorbed by the motor of the pump 4, which is representative of its characteristic curve, and hence of its load. Of course, nothing prevents to monitor other controllable quantities of the motor, representative of the characteristic curve or of the load of the pump.
  • the motor of the pump 4 is a brushless motor, electronically controlled, i.e., a permanent magnet motor whose speed is controllable.
  • the control system 17 stops the treatment program (and so causes closing of the valve 12), after possible generation of at least one signalling for the user, through the device 15 and/or the device 16, and/or after generation of an error code, to be highlighted on occasion of a subsequent use of the machine.
  • One such circumstance may be considered indicative of the fact that the flow rate of water entering the machine 1 from the water supply mains is very low and implies excessively long times for the achievement of the volume of water required for execution of a treatment step.
  • the aforesaid further predetermined time interval can be for example comprised between 60 and 120 seconds, preferably between 40 and 80 seconds, and more preferably be of about 60 seconds.
  • the control system 17 drives the motor of the pump 4 to a second speed, preferably greater than the first speed, very preferably at the washing speed. Thereafter, the system 17 evaluates again the current absorption (or other characteristic signal) of the motor of the pump 4: if this signal reaches and/or exceeds a second threshold value, the system 17 controls prosecution of the treatment program in the usual way.
  • control system 17 controls a new opening of the valve 12, evaluates again the absorption (or other characteristic signal) and when this signal reaches the second threshold value - indicative of the achievement of at least a volume or level of water in the tub appropriate for the execution of the treatment - the control system 17 controls closuring of the valve 12 and controls continuation of the treatment program, in the usual way. It will be appreciated that, based on the experimental data stored in the control system 17, the latter is capable to know which value or range of values of current absorption that - at the washing speed of the motor of the pump 4 - corresponds to a water level in the tub which is deemed to be sufficient for the execution of an efficient treatment.
  • the invention has been exemplified in relation to a water conducting household electric appliance using an impeller-type volumetric meter, but the invention is susceptible of use also in the case of other types of filling sensors, such as pneumatic-type sensors or optical-type sensors.
  • the filling sensor provided in accordance with the invention may be a sensor arranged on a supplying line that extends from one such internal reservoir internal of the household electric appliance to the treatment container thereof.
