Abstract
Description
La présente invention se rapporte a' un lave-vaisselle ménager comportant au moins un panier destiné à contenir les objets à laver, qui est mobile dans la chambre de lavage, et un dispositif de projection d'eau de lavage solidaire du panier. The present invention relates to a household dishwasher comprising at least one basket intended to contain the objects to be washed, which is movable in the washing chamber, and a device for spraying washing water integral with the basket.
Dans cette technique, on connaît déjà des agencements dans lesquels le bras de lavage tourillonne directement sur le panier et qui comportent une conduite de liquide de lavage reliée â ce bras. Ce type d'agencement supprime la nécessité d'utiliser un tuyau de pression central monté verticalement dans la chambre de lavage pour acheminer le liquide à un bras de lavage monté en haut de ce tube. Toutefois, dans ces-constructions déjà connues, le panier de lavage doit être agence dans une position de travail donnée. Lorsqu'on a â laver des objets de dimensions très différentes, il est souhaitable de pouvoir déplacer le panier en hauteur dans la chambre de lavage, de manière à pouvoir utiliser cette chambre de lavage de façon optimale.Pour obtenir une meilleure utilisation du volume de la chambre de lavage, il est également nécessaire de déplacer le bras de lavage conjointement avec le panier, de sorte que le raccordement du bras de lavage au circuit de lavage doit pouvoir être modifié en fonction de la hauteur choisie pour le panier. In this technique, arrangements are already known in which the washing arm pivots directly on the basket and which comprise a washing liquid line connected to this arm. This type of arrangement eliminates the need to use a central pressure hose mounted vertically in the washing chamber to convey the liquid to a washing arm mounted at the top of this tube. However, in these already known constructions, the washing basket must be arranged in a given working position. When objects of very different dimensions have to be washed, it is desirable to be able to move the basket in height in the washing chamber, so as to be able to use this washing chamber optimally. To obtain better use of the volume of the washing chamber, it is also necessary to move the washing arm together with the basket, so that the connection of the washing arm to the washing circuit must be able to be modified according to the height chosen for the basket.
L'invention apporte une solution au problème du raccordement d'un bras de lavage à un tuyau de pression, dans laquelle le bras de lavage peut être réglé individuellement en hauteur de manière à assurer une utilisation optimale du volume de la chambre de lavage dans le cas où les objets à laver présentent différentes hauteurs. Le réglage en hauteur du bras de lavage dans cette plage de réglage peut s'effectuer par pas successifs ou sans palier mais il exige la présence d'un dispositif de raccordement a' un tuyau de pression dans l'une des parois de la chambre de lavage.Le dispositif de raccordement comporte une liaison soudable entre le tuyau de pression et une conduite aboutissant au bras de lavage et établit un raccordement étanche lorsque le bras de lavage se trouve en position de travail dans un ou plusieurs plans qu'on peut choisir à volonté à l'intérieur du volume de lavage. Dans la forme de réalisation suivant l'invention, on obtient ces perfectionnements d'un dispositif de lavage grâce au fait que la colonne montante 10 est munie d'au moins deux trous équipés de clapets unidirectionnels 17 , 18 et en ce que la conduite présente un embout 24 adapté pour être raccordé à l'un de ces trous. The invention provides a solution to the problem of connecting a washing arm to a pressure hose, in which the washing arm can be individually adjusted in height so as to ensure optimal use of the volume of the washing chamber in the cases where the objects to be washed have different heights. The height adjustment of the washing arm in this adjustment range can be carried out in successive steps or without leveling but it requires the presence of a device for connection to a pressure pipe in one of the walls of the chamber. The connection device comprises a weldable connection between the pressure hose and a pipe leading to the washing arm and establishes a sealed connection when the washing arm is in the working position in one or more planes that can be chosen at will inside the wash volume. In the embodiment according to the invention, these improvements of a washing device are obtained thanks to the fact that the riser 10 is provided with at least two holes fitted with one-way valves 17, 18 and in that the pipe has a tip 24 adapted to be connected to one of these holes.

- Fig. 1 is a vertical sectional view of a dishwasher equipped with a washing device according to the invention
- Fig. 2 is a vertical sectional view of a connection device provided for the washing device.
Un lave-vaisselle suivant la Fig. 1 comprend un circuit de circulation du liquide de lavage, ce liquide étant pompé dans une colonne montante 10 raccordée à deux bras de lavage 11 et 12 ; ces bras se trouvant dans une chambre de lavage 13 qui renferme un panier supérieur 14 et un panier inférieur 15 destinés à contenir les objets à laver et les paniers peuvent être extraits de la machine à travers une ouverture ménagée dans la face avant de cette machine et qui est fermée par une porte abattante 16. L'extrémité supérieure de la colonne montante comporte deux clapets unidirectionnels 17, 18 qui sont montés à des hauteurs différentes et sont constitués (dans l'exemple représenté sur la Fig.2) par deux obturateurs 19 qui sont appliqués à l'intérieur par des ressorts 20 contre des orifices 21 ménagés dans la colonne montante.Le panier supérieur 14 comporte sur sa face inférieure, un palier 22 qui reçoit le bras de lavage 12, ce palier présentant un passage pour une conduite 23 s'étendant vers l'arrière, le long de la face inférieure du panier. Cet te conduite est donc en communication avec le bras de lavage, par l'intermédiaire du palier, d'une façon qui permet au bras de tourner sans obstacle tandis que la conduite ne se déplace pas. L'extrémité arrière 24 de la conduite est de forme conique et présente des ouvertures dtentrée 25 sur ses côtés. Lorsque l'extrémité est introduite dans l'un des orifices de clapets 21, la partie conique s'appuie à joint étanche contre le bord du trou et la conduite est raccordée à la colonne montante 10 comme représenté sur la Fig.2. Le raccordement peut s'effectuer sur l'un ou l'autre des orifices 21.Sur la Fig.l, il est réalisé sur le trou supérieur, le panier 14 se trouvant alors dans une position de travail haute à l'intérieur de la chambre de lavage. Lorsqu'on utilise l'orifice inférieur de la colonne montante, le panier est placé dans une position de travail basse. Ces deux positions peuvent être choisies â volonté et les dimensions des objets à laver sont déterminantes pour le choix de la position. De chaque côté du panier, les deux parois portent deux rails de guidage 26, dont un rail supérieur et un rail inférieur. Lorsqu'on fait coulisser le panier dans une paire de rails de guidage, l'extrémité 24 rencontre l'orifice 21 du clapet correspondant, ce qui établit la communication avec la colonne montante. Pendant le lavage, le liquide de lavage s'écoule vers le bras de lavage 12 en passant dans la colonne montante 10 et dans la conduite 23. Lorsqu'on extrait le panier à travers l'ouverture de la face avant de la machine, la communication est interrompue et lworifice 21 est obturé par l'obturateur 19 du clapet. A dishwasher according to Fig. 1 comprises a circuit for circulation of the washing liquid, this liquid being pumped into a rising column 10 connected to two washing arms 11 and 12; these arms being in a washing chamber 13 which contains an upper basket 14 and a lower basket 15 intended to contain the objects to be washed and the baskets can be removed from the machine through an opening made in the front face of this machine and which is closed by a drop-down door 16. The upper end of the riser comprises two unidirectional valves 17, 18 which are mounted at different heights and are formed (in the example shown in FIG. 2) by two shutters 19 which are applied inside by springs 20 against orifices 21 formed in the riser. The upper basket 14 has on its lower face, a bearing 22 which receives the washing arm 12, this bearing having a passage for a pipe 23 extending rearwardly along the underside of the basket. This pipe is therefore in communication with the washing arm, via the bearing, in a way which allows the arm to rotate without obstacle while the pipe does not move. The rear end 24 of the pipe is conical in shape and has inlet openings 25 on its sides. When the end is introduced into one of the valve orifices 21, the conical part presses against the edge of the hole with a seal and the pipe is connected to the riser 10 as shown in FIG. 2. The connection can be made on one or other of the orifices 21. In FIG. 1, it is made on the upper hole, the basket 14 then being in a high working position inside the washing room. When using the lower opening of the riser, the basket is placed in a low working position. These two positions can be chosen at will and the dimensions of the objects to be washed are decisive for the choice of the position. On each side of the basket, the two walls carry two guide rails 26, including an upper rail and a lower rail. When the basket is slid in a pair of guide rails, the end 24 meets the orifice 21 of the corresponding valve, which establishes communication with the riser. During the washing, the washing liquid flows to the washing arm 12 passing through the riser 10 and into the pipe 23. When the basket is removed through the opening on the front of the machine, the communication is interrupted and the opening 21 is closed by the shutter 19 of the valve.
