Description
Dispositif pour retenir des corps étrangers solides avant l'ouverture d'aspiration d'une pompe de vidange. Device for retaining solid foreign bodies before the suction opening of a drain pump.
L'invention concerne un dispositif pour retenir des corps étrangers solides avant l'ouverture d'aspiration d'une pompe de vidange raccordée latéralement au carter de décantation en forme de pot d'un lave-vaisselle. The invention relates to a device for retaining solid foreign bodies before the suction opening of a drain pump connected laterally to the pot-shaped settling tank of a dishwasher.
Dans un lave-vaisselle connu par la demande de brevet allemand 14 28 394, on introduit, dans le carter de décantation en forme de pot, un corps de filtre en forme de bol, dont le fond, qui constitue un filtre grossier, est muni de deux ouvertures relativement grandes. Vers le dessus, le fond est muni d'un certain nombre de doigts coniques, destinés à retenir de petits objets solides, qui pourraient bloquer la pompe de vidange de la machine, raccordée latéralement au carter de décantation. In a dishwasher known from German patent application 14 28 394, a bowl-shaped filter body is introduced into the pot-shaped settling tank, the bottom of which, which constitutes a coarse filter, is provided of two relatively large openings. Towards the top, the bottom is provided with a certain number of conical fingers, intended to retain small solid objects, which could block the machine's drain pump, connected laterally to the decantation casing.
Le but de l'invention est de créer un dispositif supplémentaire complétant le dispositif de filtrage du lavevaisselle et destiné à retenir des corps étrangers solides. The object of the invention is to create an additional device supplementing the filtering device of the dishwasher and intended to retain solid foreign bodies.
Ce but est atteint suivant l'invention par le fait que devant l'ouverture d'aspiration, on dispose une série de saillies verticales, en forme de dents, parallèles à celle-ci, qui couvrent au moins en partie la section de l'ouverture. Ce dispositif a l'avantage de pouvoir aussi retenir des corps étrangers qui ont déjà dépassé un dispositif de filtrage placé dans le carter de décantation de la machine. Les saillies du dispositif n'offrent alors glune faible résistance au courant de liquide allant vers la pompe de vidange. This object is achieved according to the invention by the fact that in front of the suction opening, there is a series of vertical projections, in the form of teeth, parallel to it, which at least partially cover the section of the opening. This device has the advantage of also being able to retain foreign bodies which have already passed a filtering device placed in the decantation casing of the machine. The protrusions of the device then do not offer a low resistance to the flow of liquid going to the drain pump.
Suivant un agencement avantageux de l'invention, les saillies partent du fond du carter de décantation et elles s'étendent au moins approximativement jusqu'au milieu de l'ouverture d'aspiration. According to an advantageous arrangement of the invention, the projections start from the bottom of the decantation casing and they extend at least approximately to the middle of the suction opening.
Suivant une autre disposition de l'invention, les saillies ont un flanc avant qui descend vers le milieu du carter de décantation. Cela est avantageux par le fait que les corps étrangers ainsi retenus sont dérivés du parcours du liquide vers le fond du carter de décantation. According to another arrangement of the invention, the projections have a front flank which descends towards the middle of the decantation casing. This is advantageous in that the foreign bodies thus retained are derived from the path of the liquid towards the bottom of the settling tank.
On expliquera l'invention plus en détail à l'aide d'un mode de réalisation donné à titre d'exemple et représenté au dessin annexé. Dans ce dessin
la figure 1 représente une coupe de la cuve d'évacuation d'un lave-vaisselle comportant, dans le carter de décantation, un dispositif pour retenir des corps étrangers solides devant l'ouverture d'aspiration d'une pompe de vidange,et
la figure 2 représente une vue du dispositif placé dans le carter de décantation, vu dans le sens de la flèche Il de la figure 1.The invention will be explained in more detail using an embodiment given by way of example and shown in the accompanying drawing. In this drawing
FIG. 1 represents a section of the drain tank of a dishwasher comprising, in the settling tank, a device for retaining solid foreign bodies in front of the suction opening of a drain pump, and
FIG. 2 represents a view of the device placed in the decantation casing, seen in the direction of the arrow II in FIG. 1.
La figure 1 représente la cuve d'évacuation 10 d'un lavevaisselle non représenté; cette cuve contient un filtre fin 11 à chemise cylindrique et axe vertical. A l'intérieur du filtre fin, est logé coaxialement un filtre grossier 12 à chemise également cylindrique et comportant des mailles plus grandes que celles du filtre fin. A partir du fond 13 du filtre grossier 12, la cuve d'évacuation 10 se transforme en un carter de décantation 14 en forme de pot. Sur ce dernier est branchée, par l'intermédiaire d'une ouverture d'aspiration 15, une pompe 16 pour la vidange du liquide de lavage du lavevaisselle. Le sens de déplacement du liquide pendant la vidange par la pompe 16 est indiqué par des flèches 17. Figure 1 shows the drain tank 10 of a dishwasher not shown; this tank contains a fine filter 11 with cylindrical jacket and vertical axis. Inside the fine filter, is housed coaxially a coarse filter 12 also cylindrical jacket and having larger meshes than those of the fine filter. From the bottom 13 of the coarse filter 12, the evacuation tank 10 is transformed into a decantation casing 14 in the form of a pot. On the latter is connected, via a suction opening 15, a pump 16 for draining the washing liquid from the dishwasher. The direction of movement of the liquid during draining by the pump 16 is indicated by arrows 17.
Pour que la pompe de vidange 16 ne puisse pas être bloquée par des corps étrangers solides, il est prévu, dans B carter de décantation 14, un dispositif 18 destiné à retenir ces corps étrangers, s'ils ne l'ont pas été par le filtre grossier 12. Le dispositif 18 se compose d'une série de saillies verticales en forme de dents 19 parallèles à l'ouverture d'aspiration 15, qui partent du fond 20 du carter de décantation 14 et s'étendent environ jusqu'au milieu de l'ouverture d'aspiration (figure 2). Par ailleurs, les dents en saillie 19, qui avancent jusqu'à une courte distance de l'ouverture d'aspiration 15, sont munies d'un flanc amont 21 descendant vers le milieu du carter de décantation. Le dispositif 18 en forme de peigne peut retenir des corps étrangers solides 22 provenant du liquide qui coule vers la pompe de vidange 16 et les dériver vers le fond 20 du carter de décantation, où ils se déposent. So that the drain pump 16 cannot be blocked by solid foreign bodies, there is provided, in B settling housing 14, a device 18 intended to retain these foreign bodies, if they have not been locked by the coarse filter 12. The device 18 consists of a series of vertical tooth-like projections 19 parallel to the suction opening 15, which start from the bottom 20 of the settling tank 14 and extend approximately to the middle the suction opening (Figure 2). Furthermore, the projecting teeth 19, which advance to a short distance from the suction opening 15, are provided with an upstream flank 21 descending towards the middle of the decantation casing. The device 18 in the form of a comb can retain solid foreign bodies 22 coming from the liquid which flows towards the drain pump 16 and divert them towards the bottom 20 of the decantation casing, where they are deposited.
Quand on nettoie les filtres 11 et 12, qui se retirent facilement de la cuve d'évacuation 10, le carter 14 est également bien accessible, de sorte que les corps étrangers 22 s'enlèvent facilement. When the filters 11 and 12 are cleaned, which are easily removed from the discharge tank 10, the casing 14 is also easily accessible, so that the foreign bodies 22 are easily removed.
