Definitions
- the invention relates to a dishwasher according to the preamble of claim 1.
- an outside air duct and a ventilation duct are located in a door closing the working container, both ducts having a fan wheel of a common blower motor.
- the outside air duct ends on both sides in the free atmosphere, while the secondary air duct is connected to the interior of the working container via a ventilation opening and opens into the outside air duct after the fan.
- the mouth of the ventilation channel can be closed by means of a controlled closure flap and is open when the fan is to be switched on for the dishes cleaned in the working container during the drying cycle to be carried out after the rinsing cycles have ended.
- the fan wheels of the fan then convey air through both channels, the moisture-laden exhaust air extracted from the working container being mixed with the fresh air from the fresh air channel. This prevents condensation from forming in the channels and concentrated steam from escaping into the installation space of the dishwasher.
- there is a specially equipped one Fan with two fan wheels required which also requires a specially adapted fan housing.
- the invention has for its object to take measures in a dishwasher according to the preamble of claim 1, through which an effective removal of steam and moisture from the working container is possible with little effort.
- the blow-out air is pressed both into the outside air duct and into the secondary air duct opening into the working container with a simple fan.
- the fresh air thus blown into the working container can then sweep past the damp, warmed up dishes and absorb moisture, which then enters the outside air duct through the ventilation opening arranged in the upper region of the working container and mixes there with the conveyed fresh air.
- the distribution of the air flow conveyed by the fan can be set rigidly.
- the fan is preferably followed by a flow divider chamber with an outlet for the outside air duct and an outlet for the secondary air duct, in which a control flap is provided for changing the amount of air flowing out through the ducts.
- the control flap can be controlled in such a way that a smaller amount of fresh air flows into the working container than in an advanced drying process.
- the control flap can be controlled depending on the moisture content of the air after the opening of the ventilation opening. However, it can also be based on experience can be controlled depending on the time.
- a control is assigned to the control flap, which can be designed as an electric motor, as a magnet or as an expansion regulator with electrically controllable heating.
- a heating element can also be arranged in the secondary air duct, which heating element can also be switched depending on the humidity or time-dependent by the program switch controlling the machine program.
- the ventilation opening is provided with a controllable closure flap in order to prevent the outflow of moist air outside the drying cycle.
- a housing 2 of a household dishwasher surrounds a working container 3, in which spray arms, which are rotatably mounted in horizontal planes, are arranged below dishware baskets 4 which do not show the dishes to be cleaned and which hold dishes.
- the spray arms are supplied with flushing liquid via lines 5, which are sucked off by a circulating pump 6 from a drain pan 8 let into the bottom 7 of the working container 3 and conveyed individually or together into the lines to the spray arms 4 via a reversing device (not shown).
- Within the device housing 2 there is a fan 9 in the area below the base 7, the air intake opening 10 of which opens freely in the device housing 2. The fan thus draws in air during operation, which is preheated by the circulation pump and other heat-generating components.
- a flow divider chamber 12 connects to the outlet port 11 of the ventialtor 9, from which a secondary air duct 13 and a fresh air duct 14 branch off.
- the secondary air duct 13 opens into the work area 3 in the lower area, preferably below the lower spray arm but above the maximum liquid level that occurs, while the fresh air duct 14 leads upwards outside the work area 3, where one in the upper area, in particular above the upper spray arm 4 in the work area 3 provided ventilation opening 15 opens into the fresh air duct 14.
- the fresh air duct 14 is formed in the region of the vent opening 15 as a mixing chamber 16, from which an exhaust air duct 17 is preferably guided to the front in the region of the door associated with the working container 3 and opens out there freely via a blow-out opening.
- the ventilation opening 15 is assigned a closure flap 18 which can be actuated by a drive device, in particular an electromagnet 19.
- a control flap 20 is additionally arranged in the flow dividing chamber 12, with which the flow path to one of the channels 13, 14 can be narrowed alternately.
- the control flap 20 is connected to a controller 21, via which the control flap can be controlled in a functionally correct manner.
- the dishes present in the working container 3 are dried in a subsequent drying cycle.
- the otherwise closed closure flap 16 is brought into the open position via the control magnet 19 and the fan 9 is simultaneously started up.
- fresh air is conveyed via the secondary air duct 13 into the working container 3 and the outside air duct 14.
- the fresh air conveyed into the working container 3 presses a corresponding amount of moisture-laden exhaust air from the working container 3 via the ventilation opening 15 into the mixing chamber 16, where it mixes with the fresh air conveyed directly into the outside air duct 14 by the fan 9.
- the Fresh air then no longer has moisture saturation, so that condensation does not take place in the exhaust air duct 17.
- the moisture that is carried along is also discharged to the outside in such a small amount per unit volume that no recognizable steam vapors emerge from the dishwasher.
- the control flap 20 in the flow dividing chamber 12 can be placed in front of the secondary air duct 13 via the controller 21 so that a relatively small amount of fresh air enters the working container at the beginning of the drying cycle 3 flows.
- the control flap 20 can then be opened further, so that the fresh air portion guided through the working container 3 increases and, at the end of the drying cycle, the entire fresh air flow conveyed by the fan 9 is guided through the working container 3.
- the fresh air which has already been preheated in the machine base can also be additionally heated by a heating element 22 arranged in the secondary air duct 13.
- closure flap 18 instead of the control flap 20 in such a way that the flow cross-section of the ventilation opening 15 that is released by it can be changed as a function of time or moisture. This also allows the proportion of fresh air conveyed by the fan 9 flowing into the working container 3 to be changed in accordance with the prevailing operating conditions.

Abstract
Description
Die Erfindung betrifft eine Geschirrspülmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a dishwasher according to the preamble of claim 1.
Bei einer bekannten Geschirrspülmaschine dieser Art befindet sich in einer den Arbeitsbehälter verschließenden Tür ein Außenluftkanal und ein Entlüftungskanal, wobei beiden Kanälen je ein Ventilatorrad eines gemeinsamen Gebläsemotors angeordnet ist. Der Außenluftkanal endet beidseitig in der freien Atmosphäre, während der Nebenluftkanal über eine Entlüftungsöffnung mit dem Innenraum des Arbeitsbehälters verbunden ist und nach dem Ventilator in den Außenluftkanal ausmündet. Die Mündungsöffnung des Entlüftungskanals ist mittels einer gesteuerten Verschlußklappe verschließbar, und ist offen, wenn der Ventilator während des nach Beendigung der Spülgänge durchzuführenden Trockenganges für das im Arbeitsbehälter gereinigte Geschirr eingeschaltet werden soll. Die Ventilatorräder des Ventilators fördern dann durch beide Kanäle Luft, wobei sich die aus dem Arbeitsbehälter abgesaugte feuchtigkeitsbeladene Abluft mit der Frischluft aus dem Frischluftkanal vermischt. Hierdurch wird vermieden, daß sich Schwitzwasser in den Kanälen bildet und konzentrierte Dampfschwaden in den Aufstellungsraum der Geschirrspülmaschine austreten. Für diesen Aufbau ist jedoch ein speziell ausgestatteter Ventilator mit zwei Ventilatorrädern erforderlich, der auch ein besonders angepaßtes Gebläsegehäuse erfordert.In a known dishwasher of this type, an outside air duct and a ventilation duct are located in a door closing the working container, both ducts having a fan wheel of a common blower motor. The outside air duct ends on both sides in the free atmosphere, while the secondary air duct is connected to the interior of the working container via a ventilation opening and opens into the outside air duct after the fan. The mouth of the ventilation channel can be closed by means of a controlled closure flap and is open when the fan is to be switched on for the dishes cleaned in the working container during the drying cycle to be carried out after the rinsing cycles have ended. The fan wheels of the fan then convey air through both channels, the moisture-laden exhaust air extracted from the working container being mixed with the fresh air from the fresh air channel. This prevents condensation from forming in the channels and concentrated steam from escaping into the installation space of the dishwasher. For this setup, however, there is a specially equipped one Fan with two fan wheels required, which also requires a specially adapted fan housing.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Geschirrspülmaschine gemäß dem Oberbegriff des Anspruchs 1 Maßnahmen zu treffen, durch welche eine wirkungsvolle Entfernung von Dampf und Feuchtigkeit aus dem Arbeitsbehälter mit geringem Aufwand möglich wird.The invention has for its object to take measures in a dishwasher according to the preamble of claim 1, through which an effective removal of steam and moisture from the working container is possible with little effort.
Die Lösung dieser Ausgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1.This issue is solved according to the invention by the characterizing features of claim 1.
Bei einer Ausgestaltung einer Geschirrspülmaschine gemäß der Erfindung wird mit einem einfachen Ventilator die Ausblasluft sowohl in den Außenluftkanal wie auch in den in den Arbeitsbehälter mündenden Nebenluftkanal gedrückt. Die dadurch in den Arbeitsbehälter eingeblasene Frischluft kann dann an dem feuchten, aufgewärmten Geschirr vorbeistreichen und Feuchtigkeit aufnehmen, die danach durch die im oberen Bereich des Arbeitsbehälters angeordnete Entlüftungsöffnung in den Außenluftkanal eintritt und sich dort mit der geförderten Frischluft mischt. Die Aufteilung des vom Ventilator geförderten Luftstroms kann starr eingestellt sein. Vorzugsweise ist dem Ventilator jedoch eine Strömungsteilerkammer mit einem Ausgang für den Außenluftkanal und einem Ausgang für den Nebenluftkanal nachgeschaltet, in der sich eine Steuerklappe zur Veränderung der durch die Kanäle abströmenden Luftmenge vorgesehen ist. So kann beispielsweise bei hohem Feuchtigkeitsgehalt der Luft im Arbeitsbehälter die Steuerklappe so gesteuert sein, daß eine geringere Frischluftmenge in den Arbeitsbehälter einströmt als bei fortgeschrittenem Trocknungsprozess. Dabei kann die Steuerklappe in Abhängigkeit von dem Feuchtigkeitsgehalt der Luft nach der Einmündung der Entlüftungsöffnung gesteuert sein. Sie kann jedoch auch nach Erfahrungswerten zeitabhängig gesteuert werden. Hierzu ist der Steuerklappe eine Steuerung zugeordnet, die als Elektromotor, als Magnet oder als Ausdehnungsregler mit elektrisch steuerbarer Heizung ausgebildet sein kann. Zur Unterstützung des Trocknungsvorganges kann auch im Nebenluftkanal ein Heizelement angeordnet werden, das ebenfalls feuchtigkeitsabhängig oder zeitabhängig vom das Maschinenprogram steuernden Programmschaltwerk geschaltet werden kann. Im übrigen ist die Entlüftungsöffnung mit einer steuerbaren Verschlußklappe versehen, um das Abströmen von feuchter Luft außerhalb des Trocknungsganges verhindern zu können.In one embodiment of a dishwasher according to the invention, the blow-out air is pressed both into the outside air duct and into the secondary air duct opening into the working container with a simple fan. The fresh air thus blown into the working container can then sweep past the damp, warmed up dishes and absorb moisture, which then enters the outside air duct through the ventilation opening arranged in the upper region of the working container and mixes there with the conveyed fresh air. The distribution of the air flow conveyed by the fan can be set rigidly. However, the fan is preferably followed by a flow divider chamber with an outlet for the outside air duct and an outlet for the secondary air duct, in which a control flap is provided for changing the amount of air flowing out through the ducts. For example, if the air in the working container has a high moisture content, the control flap can be controlled in such a way that a smaller amount of fresh air flows into the working container than in an advanced drying process. The control flap can be controlled depending on the moisture content of the air after the opening of the ventilation opening. However, it can also be based on experience can be controlled depending on the time. For this purpose, a control is assigned to the control flap, which can be designed as an electric motor, as a magnet or as an expansion regulator with electrically controllable heating. To support the drying process, a heating element can also be arranged in the secondary air duct, which heating element can also be switched depending on the humidity or time-dependent by the program switch controlling the machine program. In addition, the ventilation opening is provided with a controllable closure flap in order to prevent the outflow of moist air outside the drying cycle.
Die Erfindung ist nachfolgend anhand der Prinzipskizze einer teilweise und schematisch dargestellten Geschirrspülmaschine näher erläutert.The invention is explained in more detail below with reference to the schematic diagram of a partly and schematically illustrated dishwasher.
Ein teilweise dargestelltes, mit einer Arbeitsplatte 1 versehenes Gehäuse 2 einer Haushalts-Geschirrspülmaschine umgreift einen Arbeitsbehälter 3, in dem in horizontalen Ebenen drehbar gelagerte Sprüharme unterhalb von nicht dargestellten, das zu reinigende Geschirr aufnehmenden Gerschirrkörben 4 angeordnet sind. Die Spüharme werden über Leitungen 5 mit Spülflüssigkeit versorgt, die von einer Umwälzpumpe 6 aus einer in den Boden 7 des Arbeitsbehälters 3 eingelassenen Ablaufwanne 8 abgesaugt und über eine nicht dargestellte Umsteuervorrichtung einzel oder zusammen in die Leitungen zu den Sprüharmen 4 gefördert wird. Innerhalb des Gerätegehäuses 2 befindet sich im Bereich unterhalb des Bodens 7 ein Ventilator 9, dessen Luftansaugöffnung 10 frei im Gerätegehäuse 2 ausmündet. Der Ventilator saugt somit im Betrieb Luft an, die durch die Umwälzpumpe und andere wärmeerzeugende Bauelemente vorgewärmt ist. An den Ausblasstutzen 11 des Ventialtors 9 schließt sich eine Strömungsteilerkammer 12 an, von der ein Nebenluftkanal 13 und ein Frischluftkanal 14 abzweigen. Der Nebenluftkanal 13 mündet im unteren Bereich, vorzugsweise unterhalb des unteren Sprüharmes aber oberhalb des maximalen auftretenden Flüssigkeitsniveaus in den Arbeitsbehälter 3 aus, während der Frischluftkanal 14 außerhalb des Arbeitsbehälters 3 nach oben geführt ist, wo eine im oberen Bereich, insbesondere oberhalb des oberen Sprüharms 4 im Arbeitsbehälters 3 vorgesehene Entlüftungsöffnung 15 in den Frischluftkanal 14 mündet. Der Frischluftkanal 14 ist im Bereich der Entlüftungsöffnung 15 als Mischkammer 16 ausgebildet, von der ein Abluftkanal 17 vorzugsweise zur Frontseite im Bereich der dem Arbeitsbehälter 3 zugeordneten Tür geführt ist und dort über eine Ausblasöffnung frei ausmündet. Der Entlüftungsöffnung 15 ist ein Verschlußklappe 18 zugeordnet, die von einer Antriebseinrichtung, insbesondere einem Elektromagnet 19 betätigbar ist. In der Strömungsteilerkammer 12 ist zusätzlich eine Steuerklappe 20 angeordnet, mit der wechselweise der Strömungsweg zu einem der Kanäle 13,14 verengt werden kann. Dabei ist die Steuerklappe 20 mit einer Steuerung 21 verbunden, über die die funktionsgerechte Steuerung der Steuerklappe erfolgen kann.A
Nach Beendigung der mit Spülflüssigkeit durchzuführenden Reinigungs- und Spülgänge wird in einem anschließenden Trockengang das im Arbeitsbehälter 3 vorhandene Geschirr getrocknet. Hierzu wird die sonst geschlossene Verschlußklappe 16 über den Steuermagnet 19 in Öffnungsstellung gebracht und gleichzeitig der Ventilator 9 in Betrieb gesetzt. Hierdurch wird Frischluft über den Nebenluftkanal 13 in den Arbeitsbehälter 3 und den Außenluftkanal 14 gefördert. Die in den Arbeitsbehälter 3 geförderte Frischluft drückt eine entsprechende Menge von feuchtigkeitsbeladener Abluft aus dem Arbeitsbehälter 3 über die Entlüftungsöffnung 15 in die Mischkammer 16, wo sie sich mit der unmittelbar vom Ventilator 9 in den Außenluftkanal 14 geförderten Frischluft vermischt. Die Frischluft weist dann keine Feuchtigkeitssättigung mehr auf, so daß eine Kondensation im Abluftkanal 17 nicht stattfindet. Auch wird die mitgeführte Feuchtigkeit in so geringer Menge je Volumeneinheit nach außen abgeführt, daß keine erkennbaren Dampfschwaden aus der Geschirrspülmaschine austreten.After the cleaning and rinsing cycles to be carried out with rinsing liquid have ended, the dishes present in the working
Nachdem der Feuchtigkeitsgehalt der Abluft des Arbeitsbehälters zu Beginn des Trockenvorganges wesentlich höher liegt als am Ende, kann über die Steuerung 21 die Steuerklappe 20 in der Strömungsteilerkammer 12 so vor den Nebenluftkanal 13 gestellt werden, daß zu Beginn des Trockenganges eine relativ geringe Frischluftmenge in den Arbeitsbehälter 3 einströmt. Mit zunehmendem Absinken des Feuchtigkeitsgehalts der Abluft kann dann die Steuerklappe 20 weiter geöffnet werden, so daß der durch den Arbeitsbehälter 3 geführte Frischluftanteil steigt und am Ende des Trockenganges der gesamte, vom Ventilator 9 geförderte Frischluftstrom durch den Arbeitsbehälter 3 geführt wird. Zur Unterstützung des Trocknungsvorganges kann dabei die im Maschinensockel bereits vorgewärmte Frischluft noch durch ein im Nebenluftkanal 13 angeordnetes Heizelement 22 zusätzlich aufgeheizt werden.After the moisture content of the exhaust air from the working container at the beginning of the drying process is significantly higher than at the end, the
Daneben ist es auch möglich, anstelle der Steuerklappe 20 die Verschlußklappe 18 so auszubilden, daß der von ihr freigegebene Strömungsquerschnitt der Entlüftungsöffnung 15 zeit- oder feuchtigkeitsabhängig veränderbar ist. Auch hierdurch kann der in den Arbeitsbehälter 3 einströmende Anteil der vom Ventilator 9 geförderten Frischluft den herrschenden Betriebsbedingungen entsprechend verändert werden.In addition, it is also possible to design the
Für die Förderung der für den Trockengang erforderlichen Frischluft ist somit nur ein einfacher Ventilator erforderlich, wobei in der nachgeschalteten Verzweigung bzw. im Bereich der Entlüftungsöffnung eine Beeinflussung der durch den Arbeitsbehälter 3 zu führenden Luftmenge mit einfachen Steuermittel vorgenommen werden kann.For the conveyance of the fresh air required for the drying cycle, only a simple fan is required, with the downstream branching or in the region of the ventilation opening, the amount of air to be guided through the working
