Description

  

  Filtre pour machine<B>à</B> laver    La présente invention a pour objet un filtre pour ma  chine<B>à</B> laver.  



  Le but de la présente invention est de fournir un  filtre capable de retenir les différents corps étrangers qui  se glissent éventuellement en cours de lavage et qui  empêchent l'évacuation de l'eau par la pompe lors de la  vidange. Ces corps peuvent obstruer l'entrée de la  pompe, ou bloquer le rotor<B>de</B> celle-ci, ce qui aurait pour  conséquence<B>de</B> griller le bobinage du moteur<B>de</B> la  pompe.<B>A</B> l'entrée de la pompe, le filtre permet la récu  pération de tout ce qui peut glisser entre le tambour et  la cuve de la machine<B>à</B> laver et de<B>là</B> dans le trou de  vidange.  



  Le filtre selon     Pinvention    comprend un ressort héli  coïdal disposé     centralement   <B>à</B> l'intérieur du corps du  filtre, des moyens pour amener le liquide<B>à</B> filtrer autour  dudit ressort et une ouverture centrale pour la sortie du  liquide filtré<B>à</B> travers ce ressort.  



  Ce filtre retient les corps étrangers d'une certaine  dimension, tout en laissant passer les particules de fibres  et la bourre qui sont rejetées par la pompe. Ceci permet  d'éviter la nécessité de nettoyer<B>le</B> filtre après chaque  lessive.  



  Le dessin annexé représente,<B>à</B> titre d'exemple, une  forme d'exécution du filtre faisant l'objet<B>de</B> la présente  invention.  



  La     fig.   <B>1</B> est une vue en élévation partiellement en  coupe axiale de ce filtre;  la     fig.    2 est une vue en élévation du filtre tourné  <B>de 900</B>     pai    rapport<B>à</B> la     fig.   <B>1.</B>  



  Le filtre représenté est monté sur une pompe com  portant un corps<B>1,</B> un rotor<B>à</B> ailettes 2     entramé    par un  moteur<B>3.</B> Une pièce 4 circulaire en nylon ou autre  matière est montée<B>à</B> l'intérieur du corps<B>1.</B> Cette pièce 4  comporte, venu de fabrication, un collier central<B>5</B> et  une ouverture centrale<B>6 à</B> travers laquelle l'eau est  aspirée par la pompe.

   Cette pièce 4 pourrait également  être constituée par le fond du corps du filtre<B>1'.</B> Un    ressort     héliedidal   <B>7</B> est retenu<B>à</B> une extrémité dans le  collier<B>5</B> et bute<B>à</B> l'autre extrémité contre le fond supé  rieur<B>8</B> du corps de filtre<B>1'.</B> Un joint d'étanchéité<B>9</B> est  disposé entre le corps de pompe<B>1</B> et le corps du filtre<B>1.</B>  Ces deux corps sont maintenus assemblés au moyen  d'une bride élastique<B>10</B> retenue en position fermée sur  une nervure<B>11</B> solidaire du corps de filtre<B>1.</B>  



  En vissant plus ou moins le ressort<B>3</B> dans le collier  <B>5,</B> on peut régler la distance entre les spires.  



  L'eau<B>à</B> filtrer entre par une ouverture latérale 12,  passe<B>à</B> travers les spires du ressort<B>3,</B> passe par l'ou  verture centrale<B>6</B> pour être évacuée par le rotor 2 de la  pompe<B>à</B> travers une ouverture de sortie<B>13.</B> Les déchets  qui ne pourraient pas être évacués par la pompe sont  retenus par le ressort<B>3</B> qui peut être facilement nettoyé  en dégageant la bride<B>10</B> et en séparant le corps du  filtre<B>1".</B>  



  Le filtre décrit peut être adapté aux pompes     exis-          tantes    ou éventuellement<B>à</B> la sortie de la cuve d'une       nachine   <B>à</B> laver, avant l'entrée de la pompe.



  Filter for <B> washing </B> machine The present invention relates to a filter for my washing machine.



  The aim of the present invention is to provide a filter capable of retaining the various foreign bodies which possibly slip during washing and which prevent the evacuation of water by the pump during emptying. These bodies can obstruct the inlet of the pump, or block the rotor <B> of </B> the latter, which would <B> </B> burn the winding of the <B> motor of < / B> the pump. <B> A </B> the inlet of the pump, the filter allows the collection of anything that may slip between the drum and the tank of the machine <B> to </B> wash and <B> there </B> in the drain hole.



  The filter according to the invention comprises a coil spring disposed centrally <B> within </B> the interior of the filter body, means for causing liquid <B> to </B> to filter around said spring and a central opening for. the outlet of the filtered liquid <B> through </B> through this spring.



  This filter retains foreign bodies of a certain size, while allowing fiber particles and fluff to pass through which are rejected by the pump. This avoids the need to clean <B> the </B> filter after each wash.



  The appended drawing represents, <B> by </B> by way of example, an embodiment of the filter forming the subject <B> of </B> the present invention.



  Fig. <B> 1 </B> is an elevational view partially in axial section of this filter; fig. 2 is an elevational view of the filter turned <B> of 900 </B> in relation to <B> to </B> FIG. <B> 1. </B>



  The filter shown is mounted on a pump comprising a body <B> 1, </B> a rotor <B> with </B> fins 2 driven by a motor <B> 3. </B> A circular part 4 nylon or other material is mounted <B> inside </B> the inside of the body <B> 1. </B> This part 4 comprises, from the production, a central collar <B> 5 </B> and a central opening <B> 6 to </B> through which the water is sucked by the pump.

   This part 4 could also be formed by the bottom of the body of the filter <B> 1 '. </B> A heliedidal spring <B> 7 </B> is retained <B> at </B> one end in the collar <B> 5 </B> and abuts <B> at </B> the other end against the upper bottom <B> 8 </B> of the filter body <B> 1 '. </B> A seal <B> 9 </B> is placed between the pump body <B> 1 </B> and the filter body <B> 1. </B> These two bodies are held together by means of 'an elastic flange <B> 10 </B> retained in the closed position on a rib <B> 11 </B> integral with the filter body <B> 1. </B>



  By screwing the spring <B> 3 </B> more or less into the collar <B> 5, </B> you can adjust the distance between the turns.



  The water <B> to </B> to filter enters through a side opening 12, passes <B> through </B> through the turns of the spring <B> 3, </B> passes through the central opening < B> 6 </B> to be discharged by the rotor 2 of the pump <B> to </B> through an outlet opening <B> 13. </B> Waste which could not be discharged by the pump are retained by the spring <B> 3 </B> which can be easily cleaned by releasing the flange <B> 10 </B> and separating the body from the <B> 1 "filter. </B>



  The filter described can be adapted to existing pumps or possibly <B> at </B> the outlet of the tank of a washing machine, <B> </B> before the pump inlet.
