Definitions

  • the present invention relates to a turbidity sensor for a washing machine, in particular for household use, according to the preamble of claim 1.
  • the present invention also relates to a washing machine comprising said sensor.
  • washing machines for household use such as, for example, dishwashers and laundry washing machines, use a washing liquid usually comprising water and coming from the water main, which is combined with a detergent substance (e.g. liquid, powder, tablet, etc.) and possibly with other substances for treating crockery (e.g. rinse aid) or laundry (e.g. softener).
  • a detergent substance e.g. liquid, powder, tablet, etc.
  • other substances for treating crockery e.g. rinse aid
  • laundry e.g. softener
  • the control over some variables of the washing liquid e.g. turbidity and temperature
  • some variables of the washing liquid e.g. turbidity and temperature
  • washing machines for household use with a sensor adapted to measure the properties of the washing medium, i.e. the turbidity and possibly also the temperature of the washing liquid.
  • the turbidity sensors known at the state of the art are realized to comprise a pair of optical elements for emitting and receiving, respectively, a light beam in order to measure the turbidity of the washing liquid, plus an optional additional sensor adapted to measure the temperature of said washing liquid.
  • document EP1335060A1 and document EP2004031A1 refer to a turbidity sensor for a washing machine, in particular for household use, comprising:
  • the sensor further comprises a base or cover for coupling the sensor to said washing machine, said base being associated with said enclosure.
  • the first and second housings develop parallel to a longitudinal axis of the sensor enclosure; as a consequence, in documents EP1335060A1 and EP2004031A1 the first and second housings are also referred to as "fingers", since each one of said housings is substantially shaped like a finger of a hand, and each one of such housings extends longitudinally from the common base, just like fingers extend from a hand.
  • the turbidity sensor shown in document EP1335060A1 comprises also a temperature sensor adapted to sense the temperature of the washing liquid, said temperature sensor being positioned in the second finger at a greater distance from the base compared to the second optical element.
  • the turbidity sensor shown in document EP2004031A1 comprises a temperature sensor adapted to detect the temperature of the washing liquid, said temperature sensor being positioned in an additional housing (or "finger") located between the housings for the elements constituting the turbidity sensor, wherein the temperature sensor is positioned at a shorter distance from the base compared to the distance of the first optical element and the second optical element from said base.
  • housings or "fingers” permit protecting the optical elements of the turbidity sensor and temperature sensor for detecting the properties, in particular in terms of turbidity and temperature, of the washing liquid interposed between said housings or "fingers".
  • the electronic components of the devices shown in the above-mentioned prior-art documents are then positioned on a board, in particular an electronic board made of insulating material, and connected to a printed electric circuit of said board, which also comprises terminals to permit the board to establish the electric contact and connection with other components, typically via a plug-type connection.
  • said first and second housings develop longitudinally and substantially parallel to the plane of the board whereon the first optical element, the second optical element and the temperature sensor are installed.
  • the board is so designed as to comprise appendices whereon the first optical element, the second optical element and the temperature sensor are installed, said appendices being adapted to be housed in the respective housings and also extending longitudinally and substantially parallel to the plane whereon the sensors are installed.
  • the devices shown in the above-mentioned prior-art documents are provided with a base or cover constrained to the enclosure through the interposition of at least one sealing element (e.g. a gasket) to prevent the washing liquid from entering the enclosure that contains the board and the associated components (i.e. the first optical element, the second optical element and the temperature sensor).
  • at least one sealing element e.g. a gasket
  • the turbidity sensors shown in the above-mentioned prior-art documents suffer from some drawbacks, which are mainly due to the fact that the positioning of the housings necessarily binds the distance between the first housing and the second housing (in each one there being mounted a respective transmission/reception optical element) to the dimension of the outside diameter of the sensor, i.e. the distance between the emitter element and the receiver element defines the dimension of the diameter of the sensor and hence the minimum size of the hole in the washing machine for housing the whole sensor.
  • the housing that contain the transmission and reception optical elements have a considerable length compared to their width, resulting in the possibility of alignment errors between emitter and receiver, especially when said fingers have different lengths; it is evident that an alignment error between such components will compromise the correct reading of the degree of turbidity of the washing liquid.
  • reference numeral 1 designates as a whole a turbidity sensor for a washing machine, in particular for household use, according to the present invention.
  • the washing machine is not shown in the annexed drawings; in this respect, note that the present invention especially refers to the technical field of washing machines for household use, such as, for example, dishwashers, laundry washing machines and other similar machines. It is therefore clear that the present invention is applicable to any machine requiring a measurement of the degree of turbidity of the liquid that is present therein.
  • the sensor 1 comprises an enclosure 10 adapted to be positioned in the washing machine in such a way that it is at least partially surrounded by a washing liquid, said enclosure 10 being provided with a first housing 11 and a second housing 12.
  • the sensor 1 also comprises:
  • first element 21 and the second element 22 are respectively defined as emitter/receiver and as receiver/emitter because they form a pair of elements, in particular optical ones, for respectively emitting and receiving an electromagnetic radiation, so as to be able to measure the degree of turbidity of the washing liquid which surrounds, at least partially, said enclosure 10 and which is located between the first housing 11 and the second housing 12.
  • each one of said first element 21 and second element 22 may consist of, without distinction, an element emitting or an element receiving the electromagnetic radiation, in particular an infrared radiation.
  • said electromagnetic radiation may be, for example, in the visible optical range or in the infrared range.
  • the emitter element 21, 22 transmits an electromagnetic radiation of a given intensity; depending on the degree of turbidity of the washing liquid situated between the first housing 11 and the second housing 12, such electromagnetic radiation will be absorbed or diffused in such a way that, the higher said degree of turbidity of the washing liquid, the lower the intensity of the electromagnetic radiation that will be received by the receiver element 21, 22. As a consequence, it is possible to evaluate the degree of turbidity of the washing liquid on the basis of the intensity of the electromagnetic radiation received by the receiver element 21, 22.
  • the first housing 11 and the second housing 12 develop substantially perpendicular to a longitudinal axis X-X of the enclosure 10.
  • the first housing 11 and the second housing 12 are realized in such a way as to face towards each other, in particular the enclosure 10 being so realized to comprise a recess 13 interposed between said first housing 11 and second housing 12. It is clear that, in a normal operating condition of the sensor 1 according to the present invention, the washing liquid that surrounds, at least partially, said enclosure 10, the degree of turbidity of which is to be measured, is situated in said recess 13.
  • the first housing 11 is shaped substantially as a protuberance projecting perpendicularly relative to the longitudinal axis X-X of the enclosure 10.
  • the second housing 12 is shaped substantially as a circular sector in a plan view, i.e. when viewed in a direction substantially parallel to the longitudinal axis X-X of the enclosure 10.
  • the second housing 12 is shaped substantially as a protuberance projecting perpendicularly to the longitudinal axis X-X of the enclosure 10; in substance, its shape is similar to that of the first housing 11.
  • the sensor 1 comprises a board 30, in particular an electronic board made of insulating material, provided with a plane 31 whereon the first element 21 and the second element 22 are positioned, said board 30 being positioned within the enclosure 10 in a manner such that the first housing 11 and the second housing 12 develop substantially orthogonal to said plane 31.
  • a board 30 in particular an electronic board made of insulating material, provided with a plane 31 whereon the first element 21 and the second element 22 are positioned, said board 30 being positioned within the enclosure 10 in a manner such that the first housing 11 and the second housing 12 develop substantially orthogonal to said plane 31.
  • the first element 21 and the second element 22 are positioned on the plane 31 of the board 30 in such a way that the electromagnetic radiation will develop in a direction substantially parallel to said plane 31 of the board 30 and to the longitudinal axis X-X of the enclosure 10.
  • the board 30 further comprises a circuit (not shown in the annexed drawings), in particular a printed electric circuit, to which the first element 21 and the second element 22 are connected.
  • the board 30 comprises at least one terminal 32 to allow said board 30 to be connected to other components, in particular of a washing machine.
  • said connection is implemented by means of a plug-type and/or RAST connection (like the one shown in the annexed drawings); it is however clear that the connection between the board 30 and the washing machine can also be accomplished otherwise.
  • the board 30 further comprises a notch 33 located in a portion of the board 30 comprised between the first element 21 and the second element 22, said notch 33 being adapted to match the recess 13 of the enclosure 10 when the board 30 is positioned within said enclosure 10.
  • the enclosure 10 comprises a chamber 10A adapted to house the board 30, and from which the first housing 11 and the second housing 12 extend, in particular said chamber 10A prevalently developing along said longitudinal axis A-A.
  • the peculiar features of the sensor 1 according to the present invention make it possible to overcome the drawbacks of prior-art sensors.
  • first housing 11 and second housing 12 which develop substantially perpendicular to a longitudinal axis X-X of the enclosure 10, allows positioning the first emitter/receiver element 21 and the second receiver/emitter element 22 (which form a pair of optical elements for detecting the degree of turbidity of the washing liquid) at a mutual distance that does not depend on the dimension of the outside diameter of the sensor 1. It follows that the distance between the first emitter/receiver element 21 and the second receiver/emitter element 22 does not imply any dimensional constraints as concerns either the diameter of the sensor 1 or the hole to be made in the washing machine for housing the complete sensor 1.
  • the features of the present invention make it possible to modify, as a function of the required sensitivity, the distance between the first housing 11 and the second housing 12, and also between the first emitter/receiver element 21 and the second receiver/emitter element 22, as well as to physically calibrate the liquid turbidity reading output according to the measurement requirements of specific applications.
  • the teachings of the present invention permit adjusting the distance between the first emitter/receiver element 21 and the second receiver/emitter element 22 on the basis of the different characteristics of the different types of sensors that may be used, in particular such characteristics concerning voltage intensity, optimum distance, etc.
  • the provisions of the present invention make it possible to realize the first housing 11 and the second housing 12 in such a way that they have adequate dimensions in terms of length-to-width ratio, thus facilitating the alignment between the first emitter/receiver element 21 and the second receiver/emitter element 22 and avoiding possible alignment errors.
  • the sensor 1 according to the present invention also allows measuring large liquid passage sections, thus making it also possible to measure very extended areas, the diameter of the sensor 1 being equal; in fact, in accordance with the provisions of the present invention, the distance between the housings 11, 12 (and also between the associated emitter/receiver elements 21, 22) can be changed as necessary by modifying at will the longitudinal distance between such elements, without however requiring any interventions on the dimension of the outside diameter of the sensor 1.
  • the senor 1 comprises a temperature sensor 24 adapted to sense the temperature of the washing liquid that surrounds, at least partially, the enclosure 10.
  • Said temperature sensor 24 is housed in a third housing 14 of the enclosure 10, in particular said third housing 14 being such as to prevalently develop in a direction substantially parallel to the longitudinal axis X-X of the enclosure 10.
  • the third housing 14 is so realized as to comprise:
  • the temperature sensor 24 is positioned on the plane 31 of the board 30; in particular, said temperature sensor 24 is positioned on a branch 34 of said board 30 that extends along a direction substantially parallel to the longitudinal axis X-X of the enclosure 10.
  • the sensor 1 according to the present invention is realized to comprise also the temperature sensor 14 makes it possible to obtain complete and thorough detections of the properties of the washing liquid, in particular by combining the results obtained in terms of turbidity and temperature of the liquid that surrounds, at least partially, the enclosure 10 of the sensor 1.
  • the temperature sensor 14 is exposed to contact with the liquid on more than one side, it also ensures better precision of the liquid temperature reading and a faster and more efficient reaction to changes thereof, since better heat transmission is allowed from the washing liquid to the temperature sensor 14.
  • the provisions of the present invention make it possible to position the temperature sensor 14 in a way independent of the positions of the turbidity sensing elements 21, 22, and this permits configuring each one of said components optimally to ensure better measurements of both parameters (turbidity and temperature).
  • the sensor 1 further comprises a base (or cover) 40 associated with the enclosure 10; preferably, said base 40 comprises fastening means (not shown in detail) ensuring a stable coupling between the board 30 and the base 40.
  • the enclosure 10 comprises a connecting portion 10B, in particular having a shape complementary (as especially visible in Figures 2b , 5a and 5b ) to that of the base 40 for establishing the connection between such components.
  • the second housing 12 is preferably so realized as to join said connecting portion 10B; this is provided in both the first embodiment shown in Figures 1 to 3 (wherein the second housing 12 is shaped substantially as a circular sector in a plan view) and in the second embodiment shown in Figures 4 to 5b (wherein the second housing 12 is shaped substantially as a protuberance projecting perpendicularly to the longitudinal axis X-X of the enclosure 10).
  • the second housing 10 may also be implemented in such a way that it is distinctly separated from the connecting portion 10B of the enclosure 10, without joining it.
  • the base 40 is preferably provided with coupling means (not shown), which allow coupling the sensor 1 to a washing machine.
  • the main components of the sensor 1 i.e. the enclosure 10 and/or the board 30 and/or the base 40
  • the main components of the sensor 1 are manufactured by moulding, in particular by injection moulding.
  • the enclosure 10 is preferably obtained by injection moulding of a plastic material transparent to infrared and visible light (e.g. polypropylene), and the base 40 is obtained by injection moulding of plastic materials such as polybutylene terephthalate (PBT) and/or polyamide (PA) and/or polypropylene (PP), optionally added with fibres (e.g. glass fibres).
  • a plastic material transparent to infrared and visible light e.g. polypropylene
  • the base 40 is obtained by injection moulding of plastic materials such as polybutylene terephthalate (PBT) and/or polyamide (PA) and/or polypropylene (PP), optionally added with fibres (e.g. glass fibres).
  • PBT polybutylene terephthalate
  • PA polyamide
  • PP polypropylene
  • the coupling between the enclosure 10 and the base 40 occurs through interposition of at least one sealing element (not shown in detail in the annexed drawings) in order to allow the washing liquid to penetrate into the enclosure 10.
  • the enclosure 10 is associated with the board 30 and/or with the base 40 by overmoulding, in particular by low pressure overmoulding (LPM).
  • overmoulding in particular by low pressure overmoulding (LPM).
  • LPM low pressure overmoulding
  • the temperature sensor 14 is immersed in a medium having high thermal conductivity.
  • this feature provides savings in terms of the heat conductive paste that would otherwise be required.
  • the overmoulding of the enclosure 10 is preferably carried out in such a way as to reduce the thickness of said enclosure 10 around the temperature sensor 14, thus correspondingly reducing the distance between said temperature sensor 14 and the washing liquid, and hence further increasing the precision of the washing liquid temperature reading.
  • the moulding of the enclosure 10 over the board 30 makes it possible to manufacture said enclosure 10 in a manner such that it has small dimensions, especially in terms of thickness, i.e. dimensions only slightly greater than those of said board 30, since it is no longer necessary to make the undercuts that are typically necessary for moulding traditional components.
  • the sensor 1 made in accordance with the third embodiment permits measuring flows of liquid coming from different directions; for example, the sensor 1 shown in Figures 6 to 7b is realized in such a way to be able to take a measurement of a flow of fluid coming from a direction substantially perpendicular to the plane 31 of the board 30 and also a measurement of a flow of fluid coming from a direction substantially parallel to said plane 31 of the board 30.
  • the provisions of the present invention allow positioning the first element 21 and the second element 22 forming the pair of optical elements at a mutual distance wholly independent from the dimension of the outside diameter of the sensor 1. It follows that the distance between the first emitter/receiver element 21 and the second receiver/emitter element 22 implies no dimensional constraint as concerns either the diameter of the sensor 1 or the hole in the washing machine for housing the whole sensor 1.
  • the features of the present invention permit changing the distance between the first housing 11 and the second housing 12 (and, hence, also between the first emitter/receiver element 21 and the second receiver/emitter element 22) as a function of the required sensitivity, and physically calibrating the liquid turbidity reading output according to measurement requirements of specific applications.
  • the provisions of the present invention make it possible to realize the first housing 11 and the second housing 12 in such a way that they have adequate dimensions (in particular, in terms of length-to-width ratio), thus facilitating the alignment between the first emitter/receiver element 21 and the second receiver/emitter element 22 and avoiding possible alignment errors.

  • the distance between the housings 11, 12 can be changed according to specific requirements and necessities, in particular by modifying at will the longitudinal distance between such elements, without however requiring any interventions on the dimension of the outside diameter of the sensor 1. It is therefore apparent that, since the distance between the housings 11, 12 and between the respective emitter/receiver elements 21, 22 may be quite long, the space subject to reading may be very large as well, to advantage of the accuracy and precision of the measurement taken.
  • the peculiar provisions concerning the temperature sensor 14 according to the present invention make it possible to expose it to contact with the liquid on more than one side, resulting in better precision of the liquid temperature reading and a faster and more efficient reaction to changes thereof, since better heat transmission from the liquid to the temperature sensor 14 is ensured.
