Abstract

The unit consists of a funnel (1) with a transverse sieve (4) between its cone-shaped upper end (2) and its perforated outlet end (6). The tip (8) of the funnel is also tapered to fit into the sink overflow pipe (7), which provides a constant flow of clean water. Solid waste materials (16) from the drinking glasses are held back by the sieve when the glasses are emptied into the funnel, while any remaining liq. is flushed down the overflow pipe and into the waste (10). The funnel can be taken out of the overflow to be emptied from time to time.

Description

La présente invention concerne l'élément-filtre auxiliaire pour cuvettes de rinçage, et plus particulièrement un élément destiné à une utilisation parallèle avec les éléments de débordement bien connus, tels qu'ils sont employés dans les cuvettes de rinçage dans les débits de boisson, les restaurants et les établissements similaires.The present invention relates to the auxiliary filter element for rinsing bowls, and more particularly an element intended for parallel use with the well-known overflow elements, as they are used in the rinsing bowls in drinking establishments, restaurants and similar establishments.

Comme on le sait, les cuvettes pour le rinçage des verres et autres récipients sont munies d'un élément de débordement dans l'ouverture d'écoulement, élément principalement constitué d'un tube vertical dont l'extrémité est en forme d'entonnoir. Ainsi, la cuvette de rinçage reste remplie d'eau jusqu'à l'extrémité en forme d'entonnoir, afin de rincer les verres et autres objets, tout en assurant généralement l'amenée permanente d'eau fraîche dans le bac de rinçage.As is known, the bowls for rinsing glasses and other containers are provided with an overflow element in the flow opening, an element mainly consisting of a vertical tube the end of which is funnel-shaped. Thus, the rinsing bowl remains filled with water up to the funnel-shaped end, in order to rinse the glasses and other objects, while generally ensuring the permanent supply of fresh water into the rinsing tank.

L'extrémité en forme d'entonnoir de l'élément de débordement sert à l'évacuation des restes de boisson dans les verres, tasses, ect... Il est évident que les restes solides, comme des rondelles de fruits, sachets de thé, morceaux de papier, ect... aboutissent finalement dans le bout en forme d'entonnoir. Il faut dès lors vider régulièrement, et à la main, cette extrémité en forme d'entonnoir. L'enlèvement et le renversement de l'élément de débordement seraient en effet pue pratique, car la cuvette de rinçage se viderait à chaque fois.The funnel-shaped end of the overflow element is used for the evacuation of leftover drinks in glasses, cups, ect ... It is obvious that solid remains, such as fruit rings, tea bags , pieces of paper, ect ... eventually end up in the funnel-shaped end. It is therefore necessary to empty regularly, and by hand, this funnel-shaped end. The abduction and the overturning of the overflow element would in fact be more practical, because the rinsing bowl would empty each time.

Autre désavantage de l'utilisation exclusive d'un tel élément de débordement : le tube vertical se bouche régulièrement, d'où la nécessité d'enlever l'élément de la cuvette de rinçage pour permettre de la déboucher. Au pire des cas, les restes solides passent par l'élément de débordement pour aboutir dans la conduite d'évacuation du bac de rinçage, ce qui peut occasionner des bouchages difficile à supprimer.Another disadvantage of the exclusive use of such an overflow element: the vertical tube becomes blocked regularly, hence the need to remove the element from the rinsing bowl to allow it to unclog. In the worst case, the solid remains pass through the overflow element to end up in the discharge line of the rinsing tank, which can cause blockages which are difficult to remove.

La présente invention vise à prévoir un élément-filtre auxiliaire pour cuvettes de rinçage dont l'utilisation rencontre tous les inconvénients mentionnés ci-dessus.The present invention aims to provide an auxiliary filter element for rinsing bowls, the use of which meets all the drawbacks mentioned above.

La forme préférentielle d'exécution présente, en outre, plusieurs avantages supplémentaires : par exemple, le coût de fabrication peu élevé grâce à la construction simple, l'applicabilité universelle, la durée d'emploi relativement longue avant que l'élément-filtre auxiliaire ne doive être vidé, et son montage solide dans le bac de rinçage.The preferred embodiment also has several additional advantages: for example, the low manufacturing cost due to the simple construction, the universal applicability, the relatively long service life before the auxiliary filter element must not be emptied, and its solid mounting in the rinsing tank.

A cet effet, l'élément-filtre auxiliaire de la présente invention, destiné à être utilisé de pair avec l'élément de débordement d'une cuvette de rinçage, consiste principalement en la combinaison d'un espace de filtrage ou de récupération de restes, ouvert du côté supérieure, et disposant, du côté inférieure, d'au moins UNE ouverture d'évacuation, pourvue d'un élément de filtrage et des éléments permettant de soutenir l'espace de filtrage par rapport au débordement d'un bac de rinçage.To this end, the auxiliary filter element of the present invention, intended to be used in conjunction with the overflow element of a rinsing bowl, consists mainly of the combination of a filtering or recovery space for residues , open on the upper side, and having, on the lower side, at least ONE discharge opening, provided with a filter element and elements making it possible to support the filter space in relation to the overflow of a rinsing.

Dans sa forme préférentielle d'exécution, l'élément-filtre auxiliaire présente la forme d'un entonnoir à tube perforée à rétrécissement conique, un élément de filtrage ayant été aménagé entre l'orifice et le tuyau d'entonnoir. C'est l'orifice d'entonnoir qui remplit la fonction du susdit espace de filtrage, alors que le tuyau d'entonnoir se charge de la fonction des moyens pour soutenir l'espace de filtrage par rapport à l'élément de débordementIn its preferred embodiment, the auxiliary filter element has the form of a funnel with a conical narrowed perforated tube, a filter element having been arranged between the orifice and the funnel pipe. It is the funnel orifice which fulfills the function of the above-mentioned filtering space, while the funnel pipe takes on the function of the means for supporting the filtering space with respect to the overflow element.

Il est évident que cette forme préférentielle d'exécution permet la fabrication de l'élément-filtre auxiliaire d'une pièce, en matière plastique, à un prix dès lors relativement peu élevé. Le tuyau d'entonnoir à rétrécissement conique permet un montage solide de l'élément-filtre auxiliaire dans des pièces de débordement d'un diamètre quelconque.It is obvious that this preferred embodiment allows the production of the one-piece auxiliary filter element, made of plastic, at a relatively low price. The tapered narrowing funnel pipe allows a solid mounting of the auxiliary filter element in overflow parts of any diameter.

Afin de mieux démontrer les caractéristiques de la présente invention, voici la description d'un exemple sans caractère limitatif d'une forme préférentielle d'exécution, avec renvoi aux dessins joints en annexe, dont :

  • figure 1 : section partielle de l'élément-filtre auxiliaire, objet de l'invention
  • figure 2 : vue d'en haut de l'élément-filtre auxiliaire d'après la figure nr.1
  • figure 3 : précision de l'application de l'élément-­filtre auxiliaire dans une cuvette de rinçage
In order to better demonstrate the characteristics of the present invention, here is the description of an example without limitation of a preferred embodiment, with reference to the attached drawings, including:
  • Figure 1: partial section of the auxiliary filter element, object of the invention
  • figure 2: top view of the auxiliary filter element according to figure nr.1
  • figure 3: precision of the application of the auxiliary filter element in a rinsing bowl

Ainsi qu'il a été représenté dans la figure nr. 1, l'élément-­filtre auxiliaire consiste principalement en un espace de filtrage ou de récupération de restes 3, ouvert du côté supérieur 2 et muni, en bas d'au moins UNE ouverture d'évacuation 5, pourvue d'un élément de filtrage 4, et de moyens 6 pour soutenir l'espace de filtrage 3 à l'égard d'un élément de débordement 7, représenté dans la figure nr. 3.As shown in figure nr. 1, the auxiliary filter element mainly consists of a filtering or recovery space for remains 3, open on the upper side 2 and provided, at the bottom with at least ONE discharge opening 5, provided with a filter element 4, and means 6 for supporting the filtering space 3 with respect to an overflow element 7, shown in FIG. 3.

L'espace de filtrage 3 se présente essentiellement sous la forme de cuvette, alors que les moyens 6 servant à soutenir l'espace de filtrage 3 à l'égard d'un élément de débordement 7, consistent en un tuyau 8 à rétrécissement conique, relié à l'ouverture d'évacuation 5 et pourvu des perforations 9. On obtient ainsi un élément-filtre en forme d'entonnoir, l'espace de filtrage 3 constituant l'orifice de l'entonnoir et le tuyau 8 constituant le tube de l'entonnoir. Il est évident qu'un tel élément-filtre auxiliaire en forme d'entonnoir peut être fabriqué d'une pièce et selon un procédé relativement simple en matière synthétique ou en métal léger.The filtering space 3 is essentially in the form of a bowl, while the means 6 serving to support the filtering space 3 with respect to an overflow element 7, consist of a pipe 8 with conical narrowing, connected to the discharge opening 5 and provided with perforations 9. A filter element is thus obtained in the form of a funnel, the filtering space 3 constituting the orifice of the funnel and the pipe 8 constituting the tube the funnel. It is It is obvious that such an auxiliary filter element in the form of a funnel can be manufactured in one piece and according to a relatively simple process made of synthetic material or light metal.

La figure 2 représente clairement l'élément-filtre 4 qui pourrait consister en une passoire ou tout objet similaire, démontable ou non.Figure 2 clearly shows the filter element 4 which could consist of a colander or any similar object, removable or not.

Il convient de remarquer que l'espace de filtrage 3 sera de préférence relativement large, pour retenir une quantité assez importante de restes solides dans l'élément-filtre auxiliaire, avant de procéder à la vidange.It should be noted that the filtering space 3 will preferably be relatively large, in order to retain a fairly large amount of solid residue in the auxiliary filter element, before proceeding with the emptying.

Le fonctionnement de l'élément-filtre auxiliaire est précisé à la figure nr. 3. L'évacuation 10 d'une cuvette de rinçage 11 est munie d'un élément de débordement connu 7, consistant en un tuyau vertical 12 dont l'extrémité est en forme d'entonnoir 13. L'eau fraîche de rinçage 14 est généralement amenée en permanence dans le bac de rinçage 11, de sorte que celui-ci ait un débit permanent d'eau 15, continuellement renouvelée, car l'eau superflue déborde au-desus l'élément de débordement 7.The operation of the auxiliary filter element is specified in figure nr. 3. The discharge 10 from a rinsing bowl 11 is provided with a known overflow element 7, consisting of a vertical pipe 12, the end of which is funnel-shaped 13. The fresh rinsing water 14 is generally brought permanently into the rinsing tank 11, so that the latter has a permanent flow of water 15, continuously renewed, since the superfluous water overflows over the overflow element 7.

Dans la présente invention, l'élément-filtre auxiliaire nr.1 est introduit avec le tuyau 8 à rétrécissement conique, dans le tube vertical 12 de l'élément de débordement 7. L'eau de rinçage, s'écoulant au dessus les bords de l'élément de débordement 7, peut être évacuée par les perforations 9 ainsi que l'indiquent les flèches. Des restes de boissons peuvent être versés par le haut dans l'élément-­filtre auxiliaire 1 pour passer également par le tuyau 8 jusqu'à l'évacuation 10 du bac de rinçage 11. D'éventuels restes solides 16 resteront évidemment sur l'élément filtre 4. Dès la présence d'une quantité relativement grande de restes solides 16 que l'on observe dans l'espace de filtrage 3, l'élément-filtre auxiliaire 1 peut simplement être enlevé et renversé. Il va de soi que la quantité d'eau de rinçage 15 reste dans la cuvette de rinçage 11 étant donné que l'élément de débordement 7 n'a pas été enlevé. La figure nr. 3 montre clairement que le tuyau 8 à rétrécissement conique permet d'utiliser l'élément-filtre auxiliaire dans les éléments de débordement 7 dont la partie verticale du tube a un quelconque diamètre.In the present invention, the auxiliary filter element nr.1 is introduced with the conical narrowing pipe 8, into the vertical tube 12 of the overflow element 7. The rinsing water, flowing over the edges of the overflow element 7, can be evacuated by the perforations 9 as indicated by the arrows. Remains of drinks can be poured from above into the auxiliary filter element 1 to also pass through the pipe 8 to the outlet 10 of the rinsing tank 11. Any solid remains 16 will obviously remain on the element filter 4. As soon as there is a relatively large quantity of solid residue 16 which is observed in the filtering space 3, the auxiliary filter element 1 can simply be removed and inverted. It goes without saying that the quantity of rinse water 15 remains in the rinse bowl 11 since the overflow element 7 has not been removed. Figure nr. 3 clearly shows that the conically narrowed pipe 8 makes it possible to use the auxiliary filter element in the overflow elements 7 whose vertical part of the tube has any diameter.

La présente invention n'est nullement limitée à la forme d'exécution décrite à titre d'exemple et reproduite sur les figures, mais un tel élément-filtre auxiliaire peut être réalisé dans toutes formes et dimensions, sans s'écarter du cadre de l'invention.The present invention is in no way limited to the embodiment described by way of example and reproduced in the figures, but such an auxiliary filter element can be produced in all shapes and sizes, without departing from the scope of the invention.
