Description

Die Erfindung betrifft einen Geschirrspüler gemäss Oberbegriff von Anspruch 1.The invention relates to a dishwasher according to the preamble of claim 1.

Eine mögliche Massnahme um in der Trocknungsphase Feuchtigkeit aus dem Bottich zu führen besteht darin, dem Bottich einen Teil der mit Dampf angereicherten Luft zu entziehen.One possible measure for leading moisture out of the tub in the drying phase is to extract part of the steam-enriched air from the tub.

Eine andere Massnahme besteht darin, die Wand des Bottichs zu kühlen, so dass sich dort Feuchtigkeit niederschlagen kann. Hierzu kann Kühlluft von aussen dem Bottich entlang geführt werden.Another measure is to cool the wall of the tub, so that moisture can precipitate there. For this purpose, cooling air can be guided from outside the tub along.

DE 9106598U beschreibt einen Geschirrspüler gemäss Oberbegriff von Anspruch 1 mit einem Ventilator, mit welchem feuchte Luft aus dem Bottich abgesogen und mit Frischluft von aussen gemischt wird. DE 9106598U describes a dishwasher according to the preamble of claim 1 with a fan with which moist air is sucked out of the tub and mixed with fresh air from the outside.

Es stellt sich die Aufgabe, einen Geschirrspüler bereitzustellen, der eine effiziente Trocknung des Geschirrs erlaubt und einen ruhigen Betrieb ermöglicht.The object is to provide a dishwasher that allows efficient drying of the dishes and allows quiet operation.

Diese Aufgabe wird vom Geschirrspüler gemäss Anspruch 1 gelöst. Demgemäss ist also mindestens ein Ventilator vorgesehen, mit welchem Kühlluft entlang mindestens einer Aussenwand des Bottichs gefördert werden kann. Weiter ist eine generell als Dampfabzug bezeichnete Vorrichtung vorgesehen, welche eine Austrittsöffnung im Bottich mit einem Unterdruckbereich verbindet. Der Unterdruckbereich ist dabei ein Bereich, in welchem mit dem Ventilator ein tieferer Druck erzeugt werden kann, als er im Bottich herrscht. Dies ermöglicht es, mit Dampf befrachtete Luft aus dem Bottich abzuziehen. Somit wird es möglich, die eingangs genannten zwei Massnahmen in apparativ einfacher Weise zu kombinieren. Kühlluft und Abluft werden gemeinsam gefördert. Zudem kommt es zu einer Durchmischung von Kühlluft und feuchter Luft vom Bottich, so dass der Feuchtegrad der Abluft reduziert werden kann. Weiter ist der Ventilator 7 in einem rückseitigen Bereich des Geschirrspülers angeordnet. Dadurch wird für die Schalldämpfung der Luftwege viel Platz geschaffen.This object is achieved by the dishwasher according to claim 1. Accordingly, at least one fan is provided, with which cooling air can be conveyed along at least one outer wall of the tub. Further, a generally referred to as a vapor extraction device is provided, which connects an outlet opening in the tub with a negative pressure region. The negative pressure area is an area in which a lower pressure can be generated with the fan than it prevails in the tub. This makes it possible to extract steam-laden air from the tub. Thus, it becomes possible to combine the aforementioned two measures in a simple manner. Cooling air and exhaust air are conveyed together. In addition, there is a mixing of cooling air and humid air from the tub, so that the degree of humidity of the exhaust air can be reduced. Further, the fan 7 is in a rear area arranged the dishwasher. This creates a lot of space for the soundproofing of the airways.

Weitere bevorzugte Ausführungen des Geschirrspülers ergeben sich aus den abhängigen Ansprüchen sowie aus, der nun folgenden Beschreibung anhand der Figuren. Dabei zeigen:

  • Fig. 1 eine erste Ausführung eines Geschirrspülers und
  • Fig. 2 eine zweite Ausführung eines Geschirrspülers.
Further preferred embodiments of the dishwasher will become apparent from the dependent claims and from, the following description with reference to FIGS. Showing:
  • Fig. 1 a first embodiment of a dishwasher and
  • Fig. 2 a second embodiment of a dishwasher.

Der Geschirrspüler gemäss Fig. 1 besitzt einen Bottich 1 zur Aufnahme des zu reinigenden Geschirrs. Nach vorne wird der Bottich 1 von einer Türe 2 begrenzt. Die übrigen Aussenwände des Bottichs 1 werden von einer Deckwand 3, einer Rückwand 4, einem Boden 5 und nicht gezeigten Seitenwänden gebildet.The dishwasher according to Fig. 1 has a tub 1 for receiving the dishes to be cleaned. To the front of the tub 1 is bounded by a door 2. The remaining outer walls of the tub 1 are formed by a top wall 3, a rear wall 4, a bottom 5 and side walls, not shown.

Zur Aufnahme und Reinigung des Geschirrs besitzt der Geschirrspüler in üblicher Weise Geschirrkörbe, Sprüharme, Wasserpumpen, Heizaggregate, Rohre, Schläuche etc., welche der Einfachheit halber in den Figuren nicht dargestellt sind. Einige dieser Komponenten, insbesondere die Pumpen, sind in einem Raum 6 (dem Sockelraum) unter-halb des Bottichs 1 angeordnet.For receiving and cleaning the dishes, the dishwasher has in a conventional manner dish racks, spray arms, water pumps, heaters, pipes, hoses, etc., which are not shown in the figures for simplicity. Some of these components, in particular the pumps, are arranged in a space 6 (the base space) below the tub 1.

Ebenfalls im Raum 6 unterhalb des Bottichs ist ein Ventilator 7 angeordnet, dessen Aufgabe es ist, Kühlluft entlang mindestens einem Teil der Aussenwände des Bottichs 1 zu führen. Die Kühlluft dient dazu, die Aussenwände während der Trocknungsphase zu kühlen, so dass sich Wasser aus der Bottichluft an diesen niederschlägt. Dieses Wasser läuft an den Boden 5 des Bottichs, von wo es abgepumpt werden kann.Also in the space 6 below the tub, a fan 7 is arranged, whose task is to guide cooling air along at least part of the outer walls of the tub 1. The cooling air serves to cool the outer walls during the drying phase, so that water precipitates from the tub air to this. This water runs to the bottom 5 of the tub, from where it can be pumped out.

In der vorliegenden Ausführung saugt der Ventilator 7 Umgebungsluft durch eine Spalte 8 unterhalb der der Türe 2 an. Diese wird durch einen Ansaugkanal 9 am Boden des Raums 6 zum Ventilator 7 geführt. Vom Ventilator 7 gelangt die Kühlluft zu einem rückseitigen Kanal 10, der z.B. zwischen der Rückwand 4 und einer hinter dem Geschirrspüler angeordneten Küchenwand 11 gebildet wird. Dort kühlt die Kühlluft die Rückwand 4. Sodann tritt die Kühlluft in einen oberen Kanal 12, der z.B. zwischen der Deckwand 3 und einer Abdeckplatte 13 gebildet wird, wo sie die Deckwand kühlt. Schliesslich tritt die Kühlluft durch einen Spalt 14 oberhalb der Türe 2 aus.In the present embodiment, the fan 7 sucks in ambient air through a gap 8 below the door 2. This is guided through an intake 9 at the bottom of the room 6 to the fan 7. From the fan 7, the cooling air passes to a rear channel 10, which is formed for example between the rear wall 4 and a kitchen wall 11 arranged behind the dishwasher. There, the cooling air cools the rear wall 4. Then the cooling air enters an upper channel 12, which is formed for example between the top wall 3 and a cover plate 13, where it cools the top wall. Finally, the cooling air exits through a gap 14 above the door 2.

Um den Kühleffekt zu erhöhen, ist im vorliegenden Beispiel die Rückwand 4 mit einer Oberflächenstruktur 15 versehen. Diese führt zu einer Verwirbelung der Kühlluft, was deren Kühlwirkung erhöht.In order to increase the cooling effect, in the present example, the rear wall 4 is provided with a surface structure 15. This leads to a turbulence of the cooling air, which increases their cooling effect.

Die Oberflächenstruktur 15 kann z.B. durch Prägen des Blechs der Rückwand 4 erzeugt werden, oder auch durch Anbringen separat gefertigter Rippen, Noppen oder ähnlicher Strukturen. Vorzugsweise verläuft mindestens ein Teil der Struktur quer zum Luftstrom, so dass die gewünschten Verwirbelungen begünstigt werden. Zusätzlich können auch Längsstrukturen, z.B. in Form klassischer Kühlrippen, vorgesehen sein.The surface structure 15 may e.g. be produced by stamping the sheet of the rear wall 4, or by attaching separately manufactured ribs, knobs or similar structures. Preferably, at least part of the structure runs transversely to the air flow, so that the desired turbulence is favored. In addition, longitudinal structures, e.g. in the form of classic cooling fins, be provided.

Im Beispiel nach Fig. 1 besitzt nur die Rückwand 1 eine solche Struktur 15. Alternativ oder zusätzlich hierzu können entsprechende Strukturen auch an anderen von der Kühlluft gekühlten Aussenseiten des Bottichs 1 vorgesehen sein.In the example below Fig. 1 has only the rear wall 1 such a structure 15. Alternatively or additionally, corresponding structures may also be provided on other cooled by the cooling air outside of the tub 1.

An der Rückseite des Geschirrspülers nach Fig. 1 ist ein Dampfabzug 16 angeordnet, der dazu dient, dem Bottich 1 mit Dampf angereicherte Luft zu entziehen. Dieser besitzt einen Luftkanal 17, mit welchem die Luft von einer Austrittsöffnung 18 in der Rückwand 4 des Bottichs 1 zu einem Unterdruckbereich 19 vor dem Ventilator 7 geführt werden kann. Der Luftkanal 17 besitzt einen ersten Abschnitt 17a und einen zweiten Abschnitt 17b. Die Luft von der Austrittsöffnung 18 gelangt zuerst in den ersten Abschnitt 17a, in welchem sie nach oben in einen höchsten Bereich 20 des Luftkanals 17 geführt wird. Kondensat, welches sich in diesem ersten Abschnitt 17a ablagert, kann somit durch die Austrittsöffnung 18 wieder zurück in den Bottich 1 laufen. Die auf diese Weise vorgetrocknete Luft durchläuft sodann den zweiten Abschnitt 17b, in welchem sie nach unten in den Unterdruckbereich 19 geführt wird. Dort wird sie mit der Kühlluft vermischt.At the back of the dishwasher after Fig. 1 a steam outlet 16 is arranged, which serves to extract the tub 1 with steam-enriched air. This has an air channel 17, with which the air can be passed from an outlet opening 18 in the rear wall 4 of the tub 1 to a negative pressure region 19 in front of the fan 7. The air channel 17 has a first portion 17a and a second portion 17b. The air from the outlet opening 18 first enters the first section 17 a, in which it is guided upwards into a highest region 20 of the air channel 17. Condensate, which deposits in this first section 17a, can thus run back into the tub 1 through the outlet opening 18. The pre-dried air in this way then passes through the second section 17 b, in which it is guided down into the negative pressure region 19. There it is mixed with the cooling air.

Das Mischverhältnis zwischen der aus dem Bottich abgesogenen Luft und der Kühlluft wird z.B. auf 1:5 eingestellt.The mixing ratio between the air sucked from the tub and the cooling air is e.g. set to 1: 5.

Um die durch die Austrittsöffnung 18 weggeförderte Luft zu ersetzen, ist in einem unteren Bereich der Rückwand 4 eine Eintrittsöffnung 23 zum Zuführen frischer Luft vorgesehen. Die Eintrittsöffnung 23 verbindet den Bottich mit dem Raum 6 unter dem Bottich 1. Diese Anordnung hat den Vorteil, dass die dem Bottich 1 zugeführte Luft von den im Raum 6 angeordneten Vorrichtungen, insbesondere Heizung und Pumpen, vorgewärmt werden kann. Optional kann die eintretende Luft mit einer geeigneten Heizung auch noch zusätzlich erwärmt werden.In order to replace the air conveyed away through the outlet opening 18, an inlet opening 23 for supplying fresh air is provided in a lower area of the rear wall 4. The inlet opening 23 connects the tub with the space 6 under the tub 1. This arrangement has the advantage that the air supplied to the tub 1 can be preheated by the devices arranged in the space 6, in particular heating and pumps. Optionally, the incoming air can also be additionally heated with a suitable heater.

Wie aus Fig. 1 ersichtlich, ist die Austrittsöffnung 18 in einem oberen Bereich des Bottichs 1 angeordnet, während der Unterdruckbereich 19 tiefer liegt, im vorliegenden Beispiel unterhalb des Bottichs 1. Dies macht es erforderlich, die Abluft nach unten zu führen. Dadurch wird ein Kamineffekt, der Luft auch bei abgeschaltetem Ventilator 7 durch Eintrittsöffnung 23 und Austrittsöffnung 18 fördern würde, vermieden.How out Fig. 1 As can be seen, the outlet opening 18 is arranged in an upper region of the tub 1, while the vacuum region 19 is lower, in the present example below the tub 1. This makes it necessary to guide the exhaust air downwards. As a result, a chimney effect, which would promote air even when the fan 7 is switched off through the inlet opening 23 and the outlet opening 18, is avoided.

Weiter ist der Ventilator 7 in einem rückseitigen Bereich des Geschirrspülers angeordnet. Dadurch wird für die Schalldämpfung der Luftwege viel Platz geschaffen.Further, the fan 7 is arranged in a rear area of the dishwasher. This creates a lot of space for the soundproofing of the airways.

Vorzugsweise besitzt der Geschirrspüler eine Ventilatorsteuerung, mit welcher der Ventilator 7 mit mindestens zwei unterschiedlichen Förderleistungen grösser Null angesteuert werden kann. Die gewünschte Förderleistung kann vom Benutzer durch Betätigung der Bedienvorrichtung des Geschirrspülers ausgewählt werden. So kann die Förderleistung des Ventilators 7 für ein speziell ruhiges Programm reduziert bzw. für ein besonders schnelles Programm erhöht werden.Preferably, the dishwasher has a fan control, with which the fan 7 can be controlled with at least two different flow rates greater than zero. The desired delivery rate can be selected by the user by operating the dishwasher's operating device. Thus, the delivery of the fan 7 can be reduced for a specially quiet program or increased for a particularly fast program.

In der Ausführung nach Fig. 1 werden die Aussenwände des Bottichs 1 von Blechen gebildet. In einer zweiten, in Fig. 2 dargestellten Ausführung, sind mindestens ein Teil der Aussenwände zusätzlich mit nicht-metallischen Schalldämmschichten 24, 25 versehen. Dabei handelt es sich um so genannte Schwerdämmfolien. Diese besitzen gute Schalldämmeigenschaften, aber dennoch eine relativ gute Wärmeleitfähigkeit, so dass die Kühlung der Bottichwände nicht beeinträchtigt wird. Schwerdämmfolien enthalten beispielsweise Teer oder Bitumen mit Zusätzen, z.B. Eisenoxid.In the execution after Fig. 1 the outer walls of the tub 1 are formed by sheets. In a second, in Fig. 2 illustrated embodiment, are at least a part of the outer walls additionally provided with non-metallic Schalldämmschichten 24, 25. These are so-called heavy insulation foils. These have good sound insulation properties, but still a relatively good thermal conductivity, so that the cooling of the tub walls is not affected. Heavy insulating foils contain, for example, tar or bitumen with additives, eg iron oxide.

In der Ausführung nach Fig. 2 wird die Kühlluft den Schalldämmschichten 24, 25 an der Rück- und Oberseite des Bottichs 1 entlang geführt. Zumindest die rückseitige Schalldämmschicht 24 ist an ihrer Aussenseite wiederum mit Strukturen 15 versehen, die zu einer Verwirbelung der Kühlluft führen. Die Strukturen können z.B. in die Oberfläche der Schalldämmschichten eingeprägt werden. Wird ein Thermoplast als Schalldämmsicht eingesetzt, so kann zur Schaffung der Strukturen z.B. eine Heissprägung eingesetzt werden.In the execution after Fig. 2 the cooling air is the sound insulation layers 24, 25 guided at the rear and top of the tub 1 along. At least the rear sound insulation layer 24 is again provided on its outside with structures 15, which lead to a turbulence of the cooling air. The structures can be embossed into the surface of the sound insulation layers, for example. If a thermoplastic used as a sound insulation, it can be used to create the structures, for example, a hot stamping.

Die gezeigten Ausführungsbeispiele können in verschiedenster Weise variiert werden. Im Folgenden werden hierzu einige Beispiele genannt.The embodiments shown can be varied in various ways. In the following some examples are mentioned.

In der Ausführung gemäss Fig. 1 und 2 befindet sich der Unterdruckbereich 19, in welchen die Luft vom Bottich gefördert wird, vor dem Ventilator 7. Alternativ hierzu kann auch eine Venturidüse oder dergleichen nach dem Ventilator eingesetzt werden.In the execution according to Fig. 1 and 2 is the negative pressure region 19, in which the air is conveyed from the tub in front of the fan 7. Alternatively, a venturi or the like can be used after the fan.

Das hier gezeigte Konzept erlaubt es, in einfacher Weise Geschirrspüler mit unterschiedlichen Konfortstufen anzubieten. In einer einfachsten Version können der Dampfabzug 16 und der Ventilator 7 weggelassen werden. Die Öffnung 18 wird geschlossen. In diesem Fall zieht aufgrund des Kamineffekts immer noch eine gewisse Menge von Raumluft an der Rückseite des Bottichs 1 nach oben und kühlt dessen Aussenwand. In einer verbesserten Version kann der Ventilator 7 auch ohne den Dampfabzug 16 verwendet werden.The concept shown here makes it easy to offer dishwashers with different levels of comfort. In a simplest version, the steam extractor 16 and the fan 7 can be omitted. The opening 18 is closed. In this case, due to the chimney effect, a certain amount of room air still pulls upwards on the rear side of the tub 1 and cools its outer wall. In an improved version, the fan 7 can be used without the steam extractor 16.
