Definitions

  • the present invention refers to an improved kind of clothes drying machine, preferably of the type for use in households, which is particularly comfortable and easy to use.
  • front-loader drying machine Even if in the following of this description it is be referred to a front-loader drying machine, it will be understood that the invention may be applied to any combined washing-and drying machine, as well as to an only drying machine, both top- and front- loader, and both with vertical or horizontal axis.
  • these lint filters are subject to clogging, and in fact they tend to clog up rather quickly, so that they make it necessary for the user to quite frequently perform a disassembly, cleaning and maintenance chore that, albeit not particularly difficult or laborious, is generally found as something that users do not like very much to carry out, so that they often tend to avoid doing it. Owing to such generally low care and concern by the users, lint filters are quite often left unattended, i.e. without any proper maintenance, so that they soon end up by getting clogged with the unavoidable result that the flow of air therethrough is sensibly slowed down, thereby deteriorating the drying performance of the machine accordingly.
  • a clothes drying machine either of the condenser-type or the exhaust-type, which is provided with a single filter for the flow of drying air, to be located at the outlet mouth of the drying-air re-circulation conduit, or exhaust conduit as the case may be, wherein this filter itself, and associated devices as it will better explained later on, is capable of automatically and permanently performing a cleaning action of said single filter, without any need for the user him/herself to carry out any cleaning or maintenance.
  • FIG. 1 is a simplified schematic view of the conduits of the drying air flow and of the condensing air flow according to the prior art, wherein the generally assigned position of the lint filter is evidenced,
  • FIGS. 2 and 3 show two views of two kinds of lint filter positioning when removed from its usual lodging, respectively placed inside the machine front wall and placed in correspondence to the inner door side, and in any case just at the drum outlet,
  • Figure 4 is an "exploded " view of the assembly containing the filter, the filtering septum and the lower collecting portion according to an improved embodiment of the invention
  • FIG. 5 is an enlarged perspective view of a basic embodiment of the invention.
  • a drying machine comprises a rotating drum 1 to hold the clothes to be dried, to which there is associated an exhaust conduit 2 for the outflow of the drying air.
  • this conduit continues by connecting to a so-called re-circulation conduit 3, which is provided in order to collect the flow of drying air exiting the drum and convey it through an appropriate condenser arrangement and, from this condenser, on again into the drum.
  • re-circulation conduit 3 which is provided in order to collect the flow of drying air exiting the drum and convey it through an appropriate condenser arrangement and, from this condenser, on again into the drum.
  • the flow of drying air thus contains a certain amount of small material which is left by the drying items and which is conventionally called: lint.
  • lint As already explained such lint are intercepted by filtering means provided with proper filtering septa 5 made of thin and very close-mesh net.
  • the instant invention use the effect of a vibration to free the filtering septum, i. e. imposes to the same septum a vibration whose characteristics will be explained in the following.
  • said filtering septum must be connected to a vibration generating means through the connection between said vibration generating means and the frame 4 of the septum, - moreover said connection between said generating means and said frame must be of such mechanical configuration so that the vibrations are conveyed in a direction which is parallel to the main plane of the same septum,
  • the vibration induced to said filtering septum must be composed by a sweep with frequency varying from the minimum frequency value, to the maximum frequency value, in order to assure that, if the vibration at a specific frequency is not able of removing some lints, than said lints are however subjected to all frequencies comprised in said sweep, so increasing the possibility that a vibration at some other and different frequency, comprised in said sweep, is able of "doing the work".
  • a further improvement refers to the optimum positioning of the filtering septum; in the facts, in order to obtain the most spontaneous lint removal, after their "loosening" from the filtering septum caused by the vibration, it was realized that the most advantageous position is when the filtering septum is vertically oriented, as in such a case the lints, which are set free, are separate by gravity from the septum itself.
  • FIG. 2 shows a machine 10 wherein the portion below the lower edge of the opening, to access to the inner drum, is connected to an outlet conduit 2 for the moisture laden air flow; said portion is shaped so as to lodge a filtering septum 5, according known means.
  • such a machine 10 is provided with a front door 11 inside which a conduit 22 is arranged, to exhaust the moisture laden air flow from the drum.
  • Said conduit 22 is conveyed either towards a discharge mouth, not shown, or and preferably towards an air recirculation circuit, this being not shown either.
  • the filter means is lodged, which is formed by a frame 4 and by a relevant filtering septum 5, vertically oriented.
  • said filter and said access mouth do show corresponding shapes so as they may match each other.
  • a device for generating vibrations 15 is solidly connected to said frame 4; therefore, very simply said, when said device 15 is being activated, the vibrations so generated are directly conducted to the frame itself, and from it to the filtering septum 5, causing the wanted effect of lint separation , and consequent their falling down by gravity.
  • the whole said filter is lodged in a proper filter body 16, inside which the filtering septum 16 is then positioned.
  • the lower portion of said filter body 16 is not closed, not even by a wide-mesh net, but is opened, and below said filter body a collecting element 17 is placed, which is able to collect and to contain the lints falling down from the above placed septum.
  • the lints are being not dispersed but may be concentrated into a proper container, which may be periodically removed and emptied from the lints themselves.
  • said frame 4 may be connected not to only to one of said vibration generators 15, but to two or more 15 and 15A of such devices, wherein such devices are placed on two sides which are substantially orthogonal to each other 18, 19, belonging to the same frame 4. It has been actually experimentally demonstrated that such solution proves to be remarkably more efficient for the lints removal, than when said devices are placed on opposite sides, or on the same side of the same frame 4.
  • the requested vibration may be generated by a very simple and cheap electro-mechanical transducer (bobbin and core)', which are properly supplied and controlled by proper means apt of generating an electric frequency at controlled frequency, well known in the art.

Abstract

La présente invention concerne un sèche-linge ou un lave-linge/sèche-linge qui comprend un tambour rotatif contenant le linge à sécher, un conduit d'air de séchage conçu pour transporter de l'air de séchage à l'intérieur du tambour rotatif et depuis l'intérieur du tambour vers l'extérieur de ce dernier, qui restera dans la pièce ou bien qui sera remis en circulation, au moins une membrane filtrante conçue pour intercepter la matière étrangère et plus spécifiquement les peluches entraînées par ledit flux d'air s'écoulant dans ledit conduit, des moyens conçus pour assurer le nettoyage de la membrane filtrante et comprenant un dispositif générant des vibrations capables de faire vibrer ladite membrane filtrante. Le dispositif générant des vibrations est mécaniquement relié à la membrane filtrante et ce couplage est tel que les vibrations générées sont transférées dans des directions qui sont parallèles à au moins un plan principal de ladite membrane filtrante.
