Description

La présente invention concerne un lave-vaisselle à cloison à multifonction.The present invention relates to a multifunctional partition dishwasher.

Les lave-vaisselle connus comprennent habituellement dans leur cuve un panier à vaisselle inférieur coulissant et non réglable en hauteur, et un panier à vaisselle supérieur coulissant souvent réglable en hauteur sur deux positions. Les chemins de guidage des roulettes de leur panier à vaisselle supérieur sont constitués par des rails fixés à deux niveaux différents sur la surface intérieure de leurs parois latérales parallèles opposées. Ces rails grèvent le prix de revient de ces lave-vaisselle et le mode de fixation de ces rails pose également des problèmes relatifs à l'étanchéité de la cuve de ces appareils.Known dishwashers usually include in their tub a sliding lower basket not adjustable in height, and a sliding upper basket often adjustable in height in two positions. The guide paths of the rollers of their upper dish basket consist of rails fixed at two different levels on the inner surface of their opposite parallel side walls. These rails strike the cost price of these dishwashers and the method of fixing these rails also poses problems relating to the tightness of the tank of these devices.

Dans les lave-vaisselle connus, lors d'un séchage de la vaisselle lavée et rincée, un rideau d'eau froide est souvent formé dans la partie inférieure de leur cuve pour accélérer la condensation et l'évacuation de la vapeur d'eau émise par la vaisselle humide chauffée. Etant donné sa position située dans une partie inférieure de la cuve de ces lave-vaisselle connus, le rideau d'eau formé ne peut pas développer sa pleine efficacité dans l'accélération de la condensation et l'évacuation de la vapeur d'eau émise par la vaisselle humide en cours de séchage, qui se trouve notamment dans la partie centrale et supérieure de la cuve de ces lave-vaisselle connus. Il en résulte que la vaisselle lavée est fréquemment mal séchée dans ces appareils connus.In known dishwashers, when drying washed and rinsed dishes, a curtain of cold water is often formed in the lower part of their tub to accelerate the condensation and evacuation of the water vapor emitted by heated wet dishes. Given its position located in a lower part of the tank of these known dishwashers, the water curtain formed cannot develop its full effectiveness in accelerating condensation and the evacuation of the water vapor emitted. by wet dishes being dried, which is located in particular in the central and upper part of the tank of these known dishwashers. As a result, the washed dishes are frequently poorly dried in these known devices.

Dans les lave-vaisselle connus, les couverts soumis au lavage sont rangés dans des paniers ajourés à couverts, disposés dans des paniers à vaisselle et arrosés, de bas en haut, de liquide par un moulinet d'arrosage tournant en-dessous de ces paniers à vaisselle. Les ajours des fonds de ces paniers à couverts sont souvent petits afin de ne pas laisser échapper les couverts. Quand les ajours sont petits, les jets de liquide d'arrosage atteignent difficilement et avec une faible vigueur, les couverts. Il en ressort que les couverts sont fréquemment mal lavés dans les lave-vaisselle connus.In known dishwashers, the cutlery subjected to washing is stored in perforated cutlery baskets, arranged in dish baskets and sprinkled, from bottom to top, with liquid by a watering reel rotating below these baskets. dishes. The openings in the funds of these baskets cutlery is often small so as not to let the cutlery escape. When the openings are small, the jets of coolant hardly reach the cutlery with low vigor. It turns out that the cutlery is frequently poorly washed in known dishwashers.

Dans les lave-vaisselle connus, des ustensiles de cuisine peuvent être lavés en même temps que la vaisselle. Cependant, leurs résultats de lavage sont habituellement médiocres, voire mauvais. En effet, lors d'une préparation des plats, les produits alimentaires dans les ustensiles sont souvent chauffés ou portés à des températures relativement élevées pour leur cuisson. Ces produits alimentaires sous l'effet de la chaleur se transforment physiquement et tendent selon leur nature à se coller, s'incruster, à se dessécher, ou à se carboniser sur la paroi des ustensiles. Les salissures qui en résultent sont souvent abondantes et très adhérentes. En comparaison avec les salissures de la vaisselle qui sont rarement portées à des températures de cuisson, les salissures des ustensiles sont en général plus difficiles et plus longues à enlever.In known dishwashers, kitchen utensils can be washed together with the dishes. However, their washing results are usually poor or even poor. In fact, during preparation of dishes, the food products in the utensils are often heated or brought to relatively high temperatures for cooking. These food products under the effect of heat are physically transformed and tend, depending on their nature, to stick, become encrusted, dry out, or carbonize on the wall of the utensils. The resulting dirt is often abundant and very adherent. Compared with soiling from dishes which are rarely brought to cooking temperatures, soiling from utensils is generally more difficult and takes longer to remove.

Dans les lave-vaisselle connus, l'effet conjugué de la température, de la pression du liquide de lavage, de l'agressivité du détergent et de la durée du lavage permet habituellement d'enlever des salissures de la vaisselle et d'obtenir de bons résultats de lavage. Cependant, la température et la pression du liquide de lavage dans ces lave-vaisselle connus ne peuvent être réglées au-delà des valeurs maximales ou limites supportables par la vaisselle sans courir le risque de les endommager. Les valeurs maximales ou limites de température et de pression du liquide de lavage admises dans des lave-vaisselles connus se révèlent souvent insuffisantes dans l'enlèvement des salissures des ustensiles pour des durées raisonnables de lavage. Les médiocres ou mauvais résultats de lavage des ustensiles de cuisine dans les lave-valsselle connus en découlent probablement.In known dishwashers, the combined effect of the temperature, the pressure of the washing liquid, the aggressiveness of the detergent and the duration of the washing usually makes it possible to remove dirt from the dishes and obtain good washing results. However, the temperature and the pressure of the washing liquid in these known dishwashers cannot be adjusted beyond the maximum or limitable values that can be supported by the dishes without running the risk of damaging them. The maximum values or limits of temperature and pressure of the washing liquid accepted in known dishwashers often prove to be insufficient in the removal of soiling from the utensils for reasonable washing times. Poor or poor washing results for kitchen utensils in known dishwashers are likely to result.

Par ailleurs, dans les lave-vaisselle connus, si les durées des programmes de fonctionnement sont prolongées au-delà des limites raisonnables, certaines salissures résistantes des ustensiles peuvent être détachées des parois de ceux-ci, mais quelquefois, avec un peu de retard, c'est-à-dire au cours d'une phase de rinçage par exemple. Dans un tel cas, ces salissures souillent le liquide de rinçage et peuvent ne pas être entièrement évacuées lors d'une vidange du liquide de rinçage et se déposer sur la vaisselle et/ou les ustensiles lavés et rincés. Ainsi, dans des lave-vaisselle connus, il n'est pas certain d'obtenir un bon résultat de lavage de la vaisselle et des ustensiles par un simple ajustement des durées de leurs programmes de fonctionnement.Furthermore, in known dishwashers, if the durations of the operating programs are prolonged beyond reasonable limits, certain resistant soiling of the utensils can be detached from the walls of the latter, but sometimes, with a little delay, that is to say during a rinsing phase for example. In such a case, this soiling will contaminate the rinsing liquid and may not be completely removed during a draining of the rinsing liquid and may settle on the dishes and / or utensils washed and rinsed. Thus, in known dishwashers, it is not certain to obtain a good result for washing dishes and utensils by simply adjusting the durations of their operating programs.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser un lave-vaisselle économique à cloison à multifonction, pouvant laver efficacement à la fois la vaisselle et les ustensiles et d'obtenir d'une manière régulière d'excellents résultats de lavage pour des durées raisonnables de lavage.The aim of the present invention is to avoid these drawbacks and makes it possible to produce an economical multifunctional partition dishwasher, capable of effectively washing both dishes and utensils and of obtaining excellent results on a regular basis. wash for reasonable wash times.

Pour mieux faire comprendre l'invention, on en décrit ci-après un certain nombre d'exemples de réalisation, l'un de ces exemples étant illustré par des dessins ci-annexés, dont :

  • - la figure 1 représente une vue partielle et schématique de face d'un lave-vaisselle et ustensiles réalisé selon l'invention, montrant une cloison à multifonction dans la cuve de l'appareil, et une porte frontale de l'appareil ouverte à l'horizontale,

To better understand the invention, a number of embodiments are described below, one of these examples being illustrated by the attached drawings, including:
  • - Figure 1 shows a partial and schematic front view of a dishwasher and utensils produced according to the invention, showing a multifunction partition in the tank of the device, and a front door of the device open to the 'horizontal,
  • FIG. 2 represents a schematic view of part of the dishwasher and utensils of FIG. 1, partially in section, and
  • - Figure 3 shows a schematic and partial view of the dishwasher and utensils of Figure 1, showing a mode of coupling of the liquid supply means of the multifunction partition of the device.

Dans la présente invention, le terme "ustensiles" désigne à la fois des ustensiles de cuisine, d'une vaisselle lourde résistante aux températures relativement élevées et aux chocs mécaniques, des couverts et accessoires de table.In the present invention, the term "utensils" designates both kitchen utensils, heavy crockery resistant to relatively high temperatures and mechanical shock, cutlery and table accessories.

Un lave-vaisselle et ustensiles 1 comprend une carrosserie 2, une cuve 3, et une porte frontale 4. Dans la cuve 3, sont montés un panier inférieur 5 pour les ustensiles, - un panier supérieur 6 pour la vaisselle, - un moulinet d'arrosage inférieur 8, - un moulinet d'arrosage supérieur 9, - un dispositif électrique chauffant 10, - un circuit de liquide d'arrosage des ustensiles 18, - et un circuit de liquide d'arrosage de la vaisselle 20, représentés schématiquement en traits discontinus, les autres organes de la machine 1 n'étant pas illustrés.A dishwasher and utensils 1 comprises a body 2, a tank 3, and a front door 4. In the tank 3, are mounted a lower basket 5 for utensils, - an upper basket 6 for dishes, - a reel d 'lower watering 8, - an upper watering reel 9, - an electric heating device 10, - a liquid spraying circuit for utensils 18, - and a liquid spraying circuit for dishes 20, shown diagrammatically in broken lines, the other parts of the machine 1 not being illustrated.

Selon une caractéristique importante, le lave-vaisselle et ustensiles 1 comprend une cloison coulissante à multifonction 14 constituant d'une part une barrière divisant la cuve 3 en deux compartiments distincts, un compartiment pour le lavage de la vaisselle 11, et un compartiment pour le lavage des ustensiles 12, et interdisant du liquide et des particules de salissures en mouvement dans le compartiment de lavage des ustensiles 12 d'atteindre le compartiment de lavage de la vaisselle 11, et d'autre part, au moins un des organes suivants : un condenseur de vapeur d'eau, un support de rotation et d'alimentation en liquide du moulinet d'arrosage de la vaisselle 9, des chemins de guidage des roulettes du panier à vaisselle 6, un dispositif fixe d'arrosage de haut en bas des paniers à couverts et/ou du panier à ustensiles 5.According to an important characteristic, the dishwasher and utensils 1 comprises a sliding multifunction partition 14 constituting on the one hand a barrier dividing the tank 3 into two separate compartments, a compartment for washing dishes 11, and a compartment for washing utensils 12, and preventing liquid and dirt particles moving in the utensil washing compartment 12 from reaching the dishwashing compartment 11, and on the other hand, at least one of the following organs: a water vapor condenser, a support for rotating and supplying liquid to the dishwashing reel 9, guides for the wheels of the dishwashing basket 6, a fixed top-to-bottom spraying device cutlery baskets and / or utensil basket 5.

Etant donné que les salissures des ustensiles sont en général abondantes et résistantes au lavage, lors d'un fonctionnement de la machine 1 grâce à la cloison coulissante 14 qui sert de barrière, les salissures détachées des ustensiles dans le compartiment 12 ne viennent pas souiller la vaisselle dans le compartiment 11. Si la température et la pression du liquide de lavage et de rinçage des ustensiles dans le compartiment 12 sont élevées et supérieures aux limites de température et pression supportables par la vaisselle, la cloison coulissante 14 empêche tout dommage provoqué par ce liquide à température et pression élevées, à la vaisselle dans le compartiment 11.Since the soiling of the utensils is generally abundant and resistant to washing, during operation of the machine 1 by virtue of the sliding partition 14 which serves as a barrier, the loose soiling of the utensils in the compartment 12 does not contaminate the dishes in compartment 11. If the temperature and pressure of the washing and rinsing liquid for utensils in compartment 12 are high and above the limits of temperature and pressure bearable by the dishes, the sliding partition 14 prevents any damage caused by this liquid at high temperature and pressure, to the dishes in the compartment 11.

La cloison coulissante à multifonction 14 est réglable en hauteur dans le cuve 3, ce qui permet une avantageuse adaptation des volumes des compartiments 11 et 12 aux quantités de vaisselle et d'ustensiles soumis au lavage.The multifunction sliding partition 14 is adjustable in height in the tank 3, which allows an advantageous adaptation of the volumes of the compartments 11 and 12 to the quantities of dishes and utensils subjected to washing.

La cloison à multifonction 14 comprend une surface centrale fermée à toute traversée de liquide et de particules de salissures entre les deux compartiments 11 et 12, et des bordures frontale et arrière ouvertes uniquement à un passage, d'une part de la vapeur entre les deux compartiments 11 et 12, et d'autre part, du liquide et de particules de salissures du compartiment de lavage de la vaisselle dans le compartiment de lavage des ustensiles 12. Une telle cloison 14 permet au lave-vaisselle et ustensiles 1 de mettre en oeuvre, plusieurs procédés de lavage des ustensiles et de la vaisselle et d'obtenir de réguliers et excellents résultats de lavage.The multifunction partition 14 includes a central surface closed to any passage of liquid and dirt particles between the two compartments 11 and 12, and front and rear edges open only to one passage, on the one hand of the steam between the two compartments 11 and 12, and on the other hand, liquid and dirt particles from the dishwashing compartment in the utensil washing compartment 12. Such a partition 14 allows the dishwasher and utensils 1 to be used , several methods of washing utensils and dishes and obtaining regular and excellent washing results.

Selon un de ces procédés, le lavage de la vaisselle et celui des ustensiles se font simultanément dans leurs compartiments respectifs, à une même température de liquide mais à des pressions de liquide différentes, une pression inférieure ou égale à une valeur limite supportable par la vaisselle pour le lavage de la vaisselle et une pression supérieure à cette valeur limite pour le lavage des ustensiles.According to one of these methods, the washing of the dishes and that of the utensils are carried out simultaneously in their respective compartments, at the same liquid temperature but at different liquid pressures, a pressure less than or equal to a limit value that can be supported by the dishes for washing dishes and a pressure higher than this limit value for washing utensils.
