Description

La présente invention concerne un lave-vaisselle à filtre de liquide.The present invention relates to a liquid filter dishwasher.

Un lave-vaisselle comprend, habituellement, au dessus d'une réserve de liquide au fond d'une cuve, où sont installées une pompe de recyclage de liquide et une pompe de vidange, un filtre à mailles de dimensions moyennes, appelé filtre moyen, destiné à retenir des particules alimentaires grosses et moyennes et, éventuellement, un microfiltre pour éliminer des microparticules alimentaires et, dans un puits de vidange, un filtre gros destiné à empêcher une entrée dans la pompe de vidange des grosses particules alimentaires qui risquent de l'obstruer ou la détériorer prématurément.A dishwasher usually includes, above a liquid reserve at the bottom of a tank, where a liquid recycling pump and a drain pump are installed, a medium-sized mesh filter, called a medium filter, intended to retain large and medium-sized food particles and, optionally, a microfilter for removing food microparticles and, in a drainage well, a large filter intended to prevent entry into the drain pump of large food particles which are liable to clog or damage it prematurely.

Le filtre moyen comprend souvent deux parties, une partie fixe solidement attachée à la cuve et une partie amovible simplement posée ou en emboîtement à ajustement glissant en vue de faciliter son enlèvement ou sa mise en place. Quand le filtre moyen est mouillé, un mince film de liquide qui recouvre sa surface empêche l'air de passer au travers de ses mailles.The medium filter often comprises two parts, a fixed part securely attached to the tank and a removable part simply placed or in a slip-fit fitting in order to facilitate its removal or its installation. When the medium filter is wet, a thin film of liquid covering its surface prevents air from passing through its mesh.

Lors d'un arrêt de la pompe de recyclage de liquide, le liquide résiduel dans les parties du circuit de liquide en aval de cette pompe de recyclage retourne dans la réserve de liquide dans le fond de la cuve et fait remonter la surface libre de cette réserve de liquide. Etant donné que le filtre moyen est mouillé, l'air piégé entre cette surface libre montante de liquide et le filtre moyen mouillé qui ne peut pas s'échapper soulève inopportunément cette partie amovible de ce filtre moyen et provoque un désassemblage de celle-ci et par conséquent une perturbation dans son action de filtrage.When the liquid recycling pump stops, the residual liquid in the parts of the liquid circuit downstream of this recycling pump returns to the liquid reserve in the bottom of the tank and brings up the free surface of this liquid reserve. Since the medium filter is wet, the air trapped between this rising free surface of liquid and the wet medium filter which cannot escape inappropriately lifts this removable part of this medium filter and causes it to be disassembled and consequently a disturbance in its filtering action.

Un autre inconvénient est lié au fait que, lorsque le filtre est mouillé, les mailles du filtre, d'un diamètre de l'ordre du mm, restent obstruées par effet capillaire et peuvent pièger un volume d'air lors d'un remplissage de la cuve par le dessous du filtre. Dans ce cas, si la détection de la quantité d'eau introduite se fait par mesure directe de la pression vue comme une hauteur d'eau, le tampon d'air piégé et comprimé modifie la mesure et la quantité d'eau "détectée" devient erronée.Another drawback is related to the fact that, when the filter is wet, the meshs of the filter, with a diameter of the order of mm, remain blocked by capillary action and can trap a volume of air during filling of the tank from below the filter. In this case, if the detection of the quantity of water introduced is done by direct measurement of the pressure seen as a water level, the trapped and compressed air buffer modifies the measurement and the quantity of "detected" water becomes erroneous.

La présente invention visant à éviter ces inconvénients permet de réaliser un lave-vaisselle économique dans lequel le filtre moyen comportant une partie fixe et une partie amovible n'est pas désassemblé et perturbé dans son action de filtrage par un retour de liquide résiduel du circuit de liquide dans la réserve de liquide dans le fond de la cuve lors d'un arrêt de la pompe de recyclage de liquide.The present invention aimed at avoiding these drawbacks makes it possible to produce an economical dishwasher in which the medium filter comprising a fixed part and a removable part is not disassembled and disturbed in its filtering action by a return of residual liquid from the circuit of liquid in the liquid reserve at the bottom of the tank when the liquid recycling pump stops.

On connaît d'après le document DE-A-2 413 790 un lave-vaisselle dans le fond de la cuve duquel est ménagé un volume retenant de l'eau servant, lors de la vidange, à nettoyer le filtre fin, ce volume communiquant avec l'air libre par une cheminée.Document DE-A-2 413 790 discloses a dishwasher in the bottom of the tank of which a volume is retained retaining water used, during emptying, to clean the fine filter, this communicating volume with the open air by a chimney.

Selon l'invention, un lave-vaisselle à filtre de liquide est caractérisé en ce que le filtre de liquide comprend dans sa surface une cheminée de mise à l'air, ce filtre étant disposé au-dessus de la surface libre de la réserve de liquide de la cuve.According to the invention, a liquid filter dishwasher is characterized in that the liquid filter comprises in its surface a vent chimney, this filter being disposed above the free surface of the reserve of tank liquid.

Pour mieux faire comprendre l'invention, on en décrit ci-après un exemple de réalisation illustré par un dessin ci-annexé montrant schématiquement et partiellement une partie inférieure d'une cuve d'un lave-vaisselle.To better understand the invention, there is described below an exemplary embodiment illustrated by an appended drawing showing schematically and partially a lower part of a tank of a dishwasher.

Dans l'exemple illustré, le lave-vaisselle 1, représenté schématiquement par des traits discontinus, comprend une cuve en tôle métallique 2 dont le fond 3 porte un puisard 4. Le fond 3 de la cuve 2, au-dessus de la réserve de liquide 5 reste recouvert par un filtre moyen 7 qui comprend deux parties, une partie fixe 8 solidement attachée à la cuve 2 et une partie amovible 9 posée sur cette cuve 2. Le lave-vaisselle 1 comprend en outre un filtre gros 12 et un microfiltre 15.In the example illustrated, the dishwasher 1, represented schematically by broken lines, comprises a metal sheet tank 2 whose bottom 3 carries a sump 4. The bottom 3 of the tank 2, above the reserve of liquid 5 remains covered by a medium filter 7 which comprises two parts, a fixed part 8 securely attached to the tank 2 and a removable part 9 placed on this tank 2. The dishwasher 1 also comprises a large filter 12 and a microfilter 15.

Lors du fonctionnement du lave-vaisselle 1, une pompe de recyclage 20 aspire du liquide de la réserve de liquide 5 et le refoule à travers une conduite 21 dans un moulinet inférieur d'arrosage 23 et à travers une canalisation 24 dans un moulinet supérieur d'arrosage sur la vaisselle pour les laver, retombe sur le fond 3 de la cuve 2, partiellement recouvert par le filtre moyen 7. Le liquide et les microparticules alimentaires traversent le filtre moyen 7 et rejoignent la réserve de liquide 5 pour être aspirés de nouveau par la pompe de recyclage 20 tandis que les particules alimentaires grosses et moyennes retenues par le filtre moyen 7 sont en général entraînées dans un puits de vidange 26 par du liquide de lavage tombant de la vaisselle pour être évacuées par une pompe de vidange non représentée. Les plus grosses particules alimentaires qui risquent d'endommager cette pompe de vidange sont retenues par le filtre gros 12. Les microparticules alimentaires sont séparées progressivement du liquide de lavage par le microfiltre 15 par un envoi, d'une manière connue, d'un courant dérivé de liquide à travers ce microfiltre 15, soit par la pompe de recyclage 20 soit par la pompe de vidange.During the operation of the dishwasher 1, a recycling pump 20 sucks liquid from the liquid reserve 5 and discharges it through a line 21 into a lower watering reel 23 and through a line 24 into an upper reel d sprinkling on the dishes to wash them, falls on the bottom 3 of the tank 2, partially covered by the medium filter 7. The liquid and the food microparticles pass through the medium filter 7 and join the liquid reserve 5 to be sucked in again by the recycling pump 20 while the large and medium food particles retained by the medium filter 7 are generally entrained in a drain well 26 by washing liquid falling from the dishes to be evacuated by a drain pump not shown. The largest food particles which risk damaging this drain pump are retained by the large filter 12. The food microparticles are progressively separated from the washing liquid by the microfilter 15 by sending, in a known manner, a current derivative of liquid through this microfilter 15, either by the recycling pump 20 or by the drain pump.

Le filtre moyen 7 ainsi traversé par le liquide de lavage tombant de la vaisselle est recouvert d'un film de liquide qui rend ce filtre 7 hermétique à l'air de manière que, lors d'un arrêt de la pompe de recyclage 20, le liquide résiduel dans les canalisations 21, 24 et dans les moulinets inférieur 23 et supérieur d'arrosage, qui retourne à la réserve de liquide 5, fait monter le niveau de la surface libre de liquide de cette réserve, comprime l'air piégé dans l'espace entre le filtre moyen 7 et cette surface libre de liquide et tend à soulever et désassembler la partie amovible 9 de ce filtre moyen 7.The medium filter 7 thus traversed by the washing liquid falling from the dishes is covered with a film of liquid which makes this filter 7 airtight so that, when the recycling pump 20 is stopped, the residual liquid in the pipes 21, 24 and in the lower reels 23 and upper sprinkler, which returns to the liquid reserve 5, raises the level of the liquid free surface of this reserve, compresses the air trapped in the space between the medium filter 7 and this free liquid surface and tends to lift and disassemble the removable part 9 of this medium filter 7.

Selon l'invention, pour éviter ces inconvénients, le filtre de liquide 7 comprend dans sa surface une cheminée de mise à l'air 28.According to the invention, to avoid these drawbacks, the liquid filter 7 comprises in its surface a vent chimney 28.

Cette cheminée 28 permet à l'air piégé entre le filtre moyen 7 et la surface libre montante de la réserve de liquide 5 de s'échapper sans provoquer un soulèvement ni un désassemblage de ce filtre moyen 7. La paroi tubulaire de la cheminée 28, saillante de la surface du filtre moyen 7 empêche efficacement le liquide de lavage chargé de particules alimentaires tombant de la vaisselle de descendre directement dans le puisard 4 à travers le trou formé dans ce filtre moyen 7 par l'alèsage de cette cheminée 28 sans subir un filtrage.This chimney 28 allows the air trapped between the medium filter 7 and the free rising surface of the liquid reserve 5 to escape without causing a lifting or disassembly of this medium filter 7. The tubular wall of the chimney 28, protruding from the surface of the medium filter 7 effectively prevents the washing liquid laden with food particles falling from the dishes from descending directly into the sump 4 through the hole formed in this medium filter 7 by the bore of this chimney 28 without undergoing a filtering.

La partie amovible 9 du filtre moyen 7 comprend une anse 30 servant à la fois de poignée facilitant la maniement de cette partie amovible 9 du filtre 7 et de cheminée de mise à l'air empêchant un soulèvement et/ou un désassemblage de cette partie amovible 9 par de l'air piégé comprimé entre le filtre moyen 7 et la surface libre montante de la réserve de liquide 5 se trouvant en dessous de ce filtre 7.The removable part 9 of the medium filter 7 comprises a handle 30 serving both as a handle facilitating the handling of this part removable 9 of the filter 7 and venting chimney preventing a lifting and / or disassembly of this removable part 9 by trapped air compressed between the medium filter 7 and the free rising surface of the liquid reserve 5 below this filter 7.

Dans l'exemple illustré, l'anse 30 comprend un premier jambage ou montant creux 31 monté par accrochage dans un trou de la partie amovible 9 du filtre moyen 7 et servant de cheminée de mise à l'air 28 qui s'ouvre à l'une des extrémités sur le côté inférieur de ce filtre moyen 7 et à l'autre extrémité sur le côté supérieur de ce filtre moyen 7, juste en dessous de la traverse 33 de l'anse pour éviter toute entrée directe, dans cette cheminée, du liquide de lavage chargé de particules alimentaires tombant de la vaisselle et un deuxième jambage ou montant plein 32 immobilisé sur la partie amovible 9 du filtre moyen 7 par un ergot de blocage 34 accroché à une saillie 35 de la paroi du puisard 4.In the example illustrated, the handle 30 comprises a first jamb or hollow upright 31 mounted by hooking in a hole in the removable part 9 of the medium filter 7 and serving as a vent chimney 28 which opens to the one of the ends on the lower side of this medium filter 7 and at the other end on the upper side of this medium filter 7, just below the cross member 33 of the handle to avoid any direct entry into this chimney, washing liquid loaded with food particles falling from the dishes and a second leg or full upright 32 immobilized on the removable part 9 of the medium filter 7 by a locking lug 34 hooked to a projection 35 of the wall of the sump 4.

Au demeurant, il y a lieu de remarquer que la réalisation de la cheminée de mise à l'air 28 sous la forme d'un jambage creux 31 s'ouvrant à l'extrémité supérieure juste en dessous de la traverse 33 de l'anse 30 tout en évitant les inconvénients de la technique antérieure, c'est-à-dire tout en présentant un interêt technique certain (on évite ainsi des retombées de gros déchets directement sous le filtre), répond également à des exigences esthétiques étant donné que la présence de cette cheminée ne peut être décelée que par les initiés. Quant à la partie horizontale de la poignée, celle-ci sert vis-à-vis de la cheminée, à la fois de "paravent" et de "parapluie".Incidentally, it should be noted that the production of the vent chimney 28 in the form of a hollow jamb 31 opening at the upper end just below the cross member 33 of the handle 30 while avoiding the drawbacks of the prior art, that is to say while presenting a certain technical interest (thus avoiding fallout of large waste directly under the filter), also meets aesthetic requirements since the presence of this chimney can only be detected by insiders. As for the horizontal part of the handle, it serves opposite the chimney, both "screen" and "umbrella".

Grâce à la cheminée de mise à l'air 28 formée, suivant l'invention, en un point de sa surface, le filtre 7 ou sa partie amovible 9 simplement posée dans le fond 3 de la cuve 2 du lave-vaisselle 1 est pourvu d'une position excellement stable qui permet à ce filtre de remplir correctement, et en permanence, son action de filtrage du liquide de lavage.Thanks to the vent chimney 28 formed, according to the invention, at a point on its surface, the filter 7 or its removable part 9 simply placed in the bottom 3 of the tank 2 of the dishwasher 1 is provided from an excessively stable position which allows this filter to correctly and permanently fill its action of filtering the washing liquid.
