Description

Die vorliegende Erfindung betrifft einen Geschirrspü­ler, insbesondere mit einer Wasserauffangwanne.The present invention relates to a dishwasher, in particular with a water collecting pan.

Zur Eindämmung der Geräuschentwicklung bei Geschirr­spülmaschinen ist es bekannt, die Geschirrspülmaschine mit einer Auskleidung aus weichem oder halbhartem Schaum zwischen dem Gehäusemantel und dem innenlie­genden Spülbehälter auszuschäumen. Das Ausschäumen erfordert einen hohen Aufwand und bewirkt, dass die zwischen dem Spülbehälter und dem Gehäusemantel an­zuordnenden Maschinenteile entweder miteingeschäumt werden, was eine Reparatur erschwert oder Geräusch­brücken bilden. (DE-Gm 7 136 896)In order to contain the noise development in dishwashers, it is known to foam the dishwasher with a lining of soft or semi-hard foam between the housing jacket and the inside washing container. Foaming requires a great deal of effort and has the effect that the machine parts to be arranged between the rinsing container and the housing jacket are either also foamed in, which makes repairs more difficult or form noise bridges. (DE-Gm 7 136 896)

Es wurde auch schon versucht, diese im Betrieb bei Geschirrspülmaschinen auftretenden Lärmquellen durch eine im Spülbehälter angeordnete Schutzvorrichtung für die Spülbehälterinnenwände gegen den Aufprall der Sprühstrahlen der Spritzvorrichtungen zu dämpfen. (DE-OS 23 47 253)Attempts have also already been made to dampen these noise sources which occur in the operation of dishwashers by means of a protective device for the inner walls of the washing tub against the impact of the spray jets from the spraying devices. (DE-OS 23 47 253)

Aber diese Massnahmen führten nicht zum angestreb­ten Erfolg.But these measures did not lead to the desired success.

Eine weitere Einrichtung zur Geräuschdämpfung bei Geschirrspülern o. dgl. offenbart die DE-OS 23 57 084, welche eine Dämpfung dadurch zu erreichen trachtet, dass zumindest ein Teil der Behälterwandungen gegen die aus den Düsen austretenden Flüssigkeitsstrahlen durch zwischengesetzte, in sich steife und freitra­gende Prallwände abgeschirmt wird. Aufgrund der ge­stiegenen Lärmempfindlichkeit bewältigt auch diese Massnahme das Problem nicht im verlangten Rahmen.Another device for noise reduction in dishwashers or the like is disclosed in DE-OS 23 57 084, which seeks to achieve damping by at least a part of the container walls against the liquid jets emerging from the nozzles through interposed, rigid and self-supporting baffle walls is shielded. Due to the increased sensitivity to noise, this measure also does not solve the problem as requested.

Die vorliegende Erfindung bezweckt die Schaffung eines Geschirrspülers, welcher im Betrieb lärmärmer ist, wobei die Lärmdämpfung auf einfache, billige und wenig störende Weise zu erreichen ist.The present invention aims to provide a dishwasher which is less noisy in operation, the noise reduction being achieved in a simple, inexpensive and unobtrusive manner.

Dieses Problem löst der erfindungsgemässe Geschirr­spüler, der sich durch einen der Ansprüche auszeich­net.This problem is solved by the dishwasher according to the invention, which is characterized by one of the claims.

Die Erfindung wird anschliessend beispielsweise an­hand einer Figur erläutert, welche in rein schemati­scher Darstellung das Innere des Unterteils eines Geschirrspülers mit der lärmdämpfenden Einbaute zeigt.The invention is subsequently explained, for example, with reference to a figure, which shows the interior of the lower part of a dishwasher with the noise-damping installation in a purely schematic representation.

In dieser Figur ist der Unterteil eines Geschirrspü­lergehäuses 1 ersichtlich, mit einem Boden 2, der Wasserauffangwanne, sowie einem Wasserabfluss 3 und einem in der Wanne gebildeten Wassersumpf 4.In this figure, the lower part of a dishwasher housing 1 can be seen, with a bottom 2, the water collecting trough, and a water drain 3 and a water sump 4 formed in the trough.

Die beiden Gehäuseseitenwände 6, welche ebenfalls dem Zubringen von Spritzwasser in die Wanne dienen, sind Träger von Laufschienen 10 für die Geschirrkör­be. Der Unterteil der Laufschienen 10 dient der Auf­nahme eines Tropfenauffangbleches 7 mit einem geneig­ten Sammelboden 9. Dieses Auffangblech 7 kann aus einem entsprechenden Material, auch Kunststoff, bestehen. In der Mitte befindet sich ein Tropfwasser­abfluss 12, welcher als Längskanal oder als mittiger Stutzen ausgeführt werden kann. Es sind ferner die von oben anfallenden Tropfen 13 dargestellt.The two housing side walls 6, which also serve to bring splashing water into the tub, are carriers of running rails 10 for the crockery baskets. The lower part of the running rails 10 serves to receive a drip collecting plate 7 with an inclined collecting base 9. This collecting plate 7 can consist of a corresponding material, including plastic. In the middle there is a drip water drain 12, which can be designed as a longitudinal channel or as a central nozzle. The drops 13 occurring from above are also shown.

Es hat sich gezeigt, dass hydraulisch bedingte Geräu­sche auf folgende Arten in Geschirrspülern entstehen:
- Propellergeräusche in der Pumpe
- Strömungsgeräusche in den Leitungen
- Sprühgeräusche durch Auftreffen von Wasserstrahlen an Gehäuseteilen
- Geräusche durch Tropfen, welche in Wasserlachen oder Wassersümpfe, insbesondere in die Auffang­wanne zurückfallen
- Geräusche durch Wandwasser, welche beim Auftreffen des an den Wänden abfliessenden Wassers in das Wasserbad der Auffangwanne entstehen.It has been shown that hydraulically induced noises occur in dishwashers in the following ways:
- Propeller noise in the pump
- Flow noise in the pipes
- Spray noises caused by water jets hitting the housing parts
- Noises caused by drops falling back into pools of water or swamps, especially into the drip pan
- Noises from wall water, which occur when the water flowing off the walls hits the water bath of the drip pan.

Eingehende Versuche liessen erkennen, dass in Geschirr­spülern die hydraulischen Geräusche die massgeblichen sind.In-depth tests showed that hydraulic noises are the most important in dishwashers.

Durch die bisher in der Technik bei Geschirrspülern vorgesehenen diesbezüglichen Massnahmen liessen sich Lärmpegel zwischen 55 und 60 dB im allgemeinen errei­chen und zwischen 50 und 55 dB bei den letzten Neu­entwicklungen. Der Wert von 50 dB gilt bei den Speziali­sten als ohne grösste Aufwendungen nicht unterschreit­bar.The measures previously taken in this regard in technology in dishwashers have generally made it possible to achieve noise levels between 55 and 60 dB and between 50 and 55 dB in the latest new developments. The specialists believe that the value of 50 dB cannot be undercut without the greatest expenditure.

Im Sinne der Erfindung zeigten Laborversuche, dass beim heutigen Stande der Technik der grösste verblei­bende Lärmanteil vom Wasser herrührt, welches in das Bad bzw. den Sumpf oder die Lache zurücktropft resp. fliesst. Es sind dies grössenordnungsmässig 80 bis 120 1/min. Es entsteht durch diese Tropfen ein Geräusch, wie man es von tropfenden Wasserhahnen kennt. Wassertropfen bilden insbesondere intensive Lärmquellen, wenn das Wasser in eine Wasserlache oder einen Wassersumpf bzw. ein Wasserbad fällt. Damit ergab sich auch schon die Möglichkeit einer Lösung, nämlich die Verhinde­rung des Abtropfens oder Abfliessens von Wasser in das Wasserbad bzw. den Wassersumpf des Geschirrspülers.In the sense of the invention, laboratory tests showed that, in the current state of the art, the largest remaining noise component comes from the water which drips back into the bath or the swamp or the pool. flows. These are on the order of 80 to 120 1 / min. These drops create a noise as is known from dripping water taps. Drops of water in particular form intensive sources of noise when the water falls into a pool of water or a water sump or a water bath. This already gave rise to the possibility of a solution, namely preventing water from dripping or running off into the water bath or the water sump of the dishwasher.

In diesem Sinne sammelt das Tropfenauffangblech 7 die von oben kommenden Wasser in Form von Tropfen oder an den Seitenwänden 6 abfliessenden Wasserfäden, welche der geneigte Sammelboden 9 über seinen Tropf­wasserabfluss 12, der vorzugsweise ins Wasserbad ein­taucht, sanft in dieses zurückführt. Messungen zeigten, dass diese Massnahme die auftretenden Geräusche um ca. 5 dB, beipsielsweise von 50 auf ca. 45 dB reduzieren kann.In this sense, the drip tray 7 collects the water coming from above in the form of drops or water threads flowing off the side walls 6, which the inclined collecting base 9 gently returns into the drip water outlet 12, which is preferably immersed in the water bath. Measurements showed that this measure can reduce the noise occurring by approx. 5 dB, for example from 50 to approx. 45 dB.

Das Tropfenauffangblech 7 kann in zwei Hälften ein­legbar bzw. zusammenlegbar ausgeführt werden. Es ist derart konzipiert, dass es auch das längs der Seiten­wände 6 abfliessende Wasser auffängt und geführt der Auffangwanne zuleitet. Das Topfenauffangblech 7 ist vorzugsweise mit Aussparungen versehen, welche den Zugriff zum darunter liegenden Filter und die Be­netzung der darunter liegenden Heizung usw. sicher­stellen. Im übrigen kann dieses Tropfenauffangblech von beliebiger geometischer Form sein, muss aber die sanfte Ableitung des aufgefangenen Wassers in das Bad sicherstellen.The drip tray 7 can be inserted or folded in half. It is designed in such a way that it also collects the water flowing along the side walls 6 and guides it to the collecting trough. The pot collecting plate 7 is preferably provided with cutouts which ensure access to the filter underneath and the wetting of the heating underneath, etc. Incidentally, this drip tray can be of any geometrical shape, but must ensure the gentle drainage of the water collected into the bath.

Es ist natürlich grundsätzlich möglich, derartige Mittel zur Verhütung des Einfallens von Flüssigkeits­tropfen in das Wasserbad bzw. in eine Wasser­lache oder einen Wassersumpf des Geschirrspülers auf eine andere als die beschriebene Art zu erreichen, nämlich:It is of course fundamentally possible in principle to achieve such means for preventing the dropping of liquid drops into the water bath or into a water pool or a water sump of the dishwasher in a manner other than that described, namely:

Das Wasserbad kann unterhalb des Bodens 2 des Ge­schirrspülergehäuses vorgesehen werden und der Boden 2 als Tropfblech wirken.The water bath can be provided below the bottom 2 of the dishwasher housing and the bottom 2 can act as a drip tray.

Es ist ferner möglich, mehrere derartige Tropfbleche, nämlich je eines unter jedem Korb, vorzusehen.It is also possible to provide several such drip trays, namely one under each basket.

Es ist grundsätzlich möglich, den Sammelboden 9 der­art geneigt auszuführen, dass die Zuleitung zum Wasser­sumpf über die untersten Teile der Gehäuseseitenwände 6 erfolgt.It is fundamentally possible to design the collecting base 9 so that the feed to the water sump takes place via the lowest parts of the housing side walls 6.

Eine weitere Möglichkeit der Lärmdämpfung kann mittels eines auf dem Wasserbad schwimmenden Deckbelages in Form schwimmender Körper, beispielsweise aus Kunststoff, insbesondere "Styropor" erfolgen oder durch Einbau eines Drahtgitters über dem Wasserbad. Es kann ferner die Bildung einzelner Inseln, welche aus dem Wasserbad herausragen, vorgesehen werden. Eine aufwendigere Ausführung, die den Erfolg bringen kann, kann in einem rotierenden Flügelrad bestehen, welches, beispielsweise in Verbindung mit dem Sprüharm, vorgesehen ist und bei dem Ableitlamellen über dem Wasserbad angeordnet werden. Es wäre auch das Erstellen eines Luftkissens über dem Wasserbad eine mögliche, erfolgversprechende Massnahme.A further possibility for noise reduction can be achieved by means of a cover covering floating in the form of a floating body, for example made of plastic, in particular “styrofoam”, or by installing a wire mesh over the water bath. The formation of individual islands which protrude from the water bath can also be provided. A more complex design, which can bring success, can consist in a rotating impeller, which is provided, for example in connection with the spray arm, and in the case of which discharge vanes are arranged above the water bath. It would also be a promising measure to create an air cushion over the water bath.

Alle in der Beschreibung und/oder der Figur dargestell­ten Einzelteile und Einzelmerkmale sowie deren Permu­tationen, Kombinationen und Variationen sind erfinde­risch und zwar für n Einzelteile und Einzelmerkmale mit den Werten n = 1 bis n → ∞.All the individual parts and individual features shown in the description and / or the figure, as well as their permutations, combinations and variations, are inventive, namely for n individual parts and individual features with the values n = 1 to n → ∞.
