Description

Die Erfindung betrifft einen Waschautomaten mit einem Gehäuse der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a washing machine with a housing of the type specified in the preamble of claim 1.

Moderne Waschautomaten der Oberklasse erfordern sowohl im Waschgang als auch im Schleudergang unterschiedliche Drehzahlen der Waschtrommel. Hierbei sollen die Schleuderdrehzahlen Werte von 1300 bis 2000 1/min haben, während für den Geräuschpegel höchstens für das Waschen LWA 47dB und für das Schleudern LWA 49dB angestrebt werden.Modern luxury washing machines require different wash drum speeds in both the wash cycle and the spin cycle. The spin speeds should be between 1300 and 2000 1 / min, while for the noise level the maximum is aimed for washing LWA 47dB and for spinning LWA 49dB.

Bisherige Waschautomaten arbeiten mit einem DC-Motor mit PWM-Chopper und riemengetriebener Trommel, wobei die höchsten Schleuderdrehzahlen bei 1400 1/min liegen. Auch sind mit diesem bekannten Automaten die oben genannten angestrebten Geräuschpegelwerte nicht zu erreichen.Previous washing machines work with a DC motor with PWM chopper and belt-driven drum, with the highest spin speeds being 1400 rpm. The known noise level values mentioned above cannot be achieved with this known machine either.

Um die gewünschten Werte bezüglich der Schleuderdrehzahlen und des niedrigen Geräuschpegels zu erreichen, ist ein U-Motor im DC-Betrieb, insbesondere aus Drehzahlgründen nicht einzusetzen, da der U-Motor von seiner Motordrehzahl her nicht über 1300 1/min zu betreiben ist. Weiterhin sind die in Frage kommenden Gleichstrommotoren mit einem nachteilig hohen Bürstenverschleiß, eine starke Geräuschentwicklung in den hohen Drehzahlen sowie den in der Funkentstörung auftretenden Schwierigkeiten behaftet.In order to achieve the desired values with regard to the spin speed and the low noise level, a U-motor in DC operation is not to be used, especially for reasons of speed, since the U-motor cannot be operated above 1300 rpm from its motor speed. Furthermore, the DC motors in question have a disadvantageously high brush wear, a high level of noise at high speeds and the difficulties encountered in radio interference suppression.

Der Erfindung liegt die Aufgabe zugrunde, einen Waschautomaten, insbesondere für die Oberklasse zu schaffen, mit dem sich alle gewünschten Drehzahlen von 25 bis 2000 1/min für den Schleudergang und für die unterschiedlichen Waschgänge ohne ungünstige Folgen erzeugen lassen. Weiterhin soll eine weitgehend gleichmäßig zu haltende Wasch- und Schleuderwirkung bei möglichst konstanten Drehzahlen und geringem Geräuschpegel erzielt werden. Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichneten Merkmale gelöst.The invention has for its object to provide an automatic washing machine, in particular for the luxury class, with which all desired speeds of 25 to 2000 1 / min can be generated for the spin cycle and for the different washing cycles without unfavorable consequences. Furthermore, a largely uniform washing and spinning effect should be kept as constant as possible Speeds and low noise level can be achieved. This object is achieved by the features characterized in claim 1.

Da die Waschtrommel mit einem hochpoligen Motor direkt angetrieben wird, kann der Forderung der Drehzahlbegrenzung, bei der die maximale Motordrehzahl mit der gewünschten hohen Schleuderdrehzahl identisch ist, entsprochen werden. Der angestrebte niedrige Geräuschpegel wird dadurch erreicht, daß der Antriebsmotor von einer Dämmhaube eingekapselt wird. Zusätzlich kann dann auch noch die Rückwand des Bottichs mit einer Geräuschdämmung versehen werden. Da der Antriebsmotor keine Bürsten aufweist und in vorteilhafter Weise als Synchronmotor mit einem Umrichter ausgebildet ist, kann die Kapselung des Motors aus thermischen Gründen ohne Bedenken vorgenommen werden. Dieses wird auch noch dadurch begünstigt, da die Elektronik nicht am Motor angeordnet ist.Since the washing drum is driven directly by a multi-pole motor, the requirement of the speed limitation, in which the maximum motor speed is identical to the desired high spin speed, can be met. The desired low noise level is achieved in that the drive motor is encapsulated by an insulation hood. In addition, the back wall of the tub can also be provided with noise insulation. Since the drive motor has no brushes and is advantageously designed as a synchronous motor with a converter, the encapsulation of the motor can be carried out without concern for thermal reasons. This is also favored because the electronics are not arranged on the motor.

Weitere vorteilhafte Ausgestaltunen des Erfindungsgegenstandes sind den weiteren Unteransprüchen zu entnehmen.Further advantageous refinements of the subject matter of the invention can be found in the further subclaims.

Die Erfindung wird anhand des in der Figur dargestellten Ausführungsbeispiels näher beschrieben.The invention is described in more detail with reference to the embodiment shown in the figure.

Ein Waschautomat 1 besitzt ein Gehäuse 3, in dem eine mechanisch schwingende Einheit 5 angeordnet ist, die aus einer waagerecht liegenden Wäschetrommel 7, einem diese umgebenden Bottich 9 und einem die Waschtrommel 7 direkt antreibenden Antriebsmotor 11 besteht. Die anderen zur Steuerung des Waschautomaten 1 notwendigen Teile sind nicht näher dargestellt.An automatic washing machine 1 has a housing 3 in which a mechanically vibrating unit 5 is arranged, which consists of a horizontally lying washing drum 7, a tub 9 surrounding it and a drive motor 11 driving the washing drum 7 directly. The other parts necessary to control the washing machine 1 are not shown in detail.

Der Antriebsmotor 11 ist als bürstenloser Motor an der Außenseite 22 der Bottichrückwand 15 angeordnet und von einer Dämmhaube 13 umgeben, durch welche die Motorgeräusche wirkungsvoll abgeschirmt werden. Hierbei ist die Dämmhaube 13 mit der Rückwand 15 des Bottichs 9 fest verbunden. Da die Steuerelektronik 16 nicht an dem Antriebsmotor 11, sondern an einer von diesem entfernten Stelle in dem Gehäuse 3, z. B. im Bereich der Vorderwand 18 angeordnet ist, kann die Kapselung des Antriebsmotors 11 ohne Bedenken vorgenommen werden, zumal der Antriebsmotor 11 auch keine Bürsten aufweist.The drive motor 11 is arranged as a brushless motor on the outside 22 of the tub rear wall 15 and surrounded by an insulation hood 13, through which the motor noises are effectively shielded. Here, the insulation hood 13 is firmly connected to the rear wall 15 of the tub 9. Since the control electronics 16 are not on the drive motor 11, but on one remote from it Place in the housing 3, for. B. is arranged in the region of the front wall 18, the encapsulation of the drive motor 11 can be carried out without hesitation, especially since the drive motor 11 also has no brushes.

Das Erreichen des gewünschten Geräuschpegels kann auch dadurch unterstützt werden, daß die Innenseite 17 der Bottichrückwand noch mit einer Dämmschicht 19 versehen wird. Der Antriebsmotor 11 ist ein Außenläufermotor, dessen als Außenläufer 23 ausgebildeter permanentmagnetischer Rotor die Antriebswelle 24 der Wäschetrommel 7 direkt antreibt. Die Antriebswelle 24 ist hierbei in einer aus zwei Wälzlagern 26, 27 bestehenden Lagerung in einer nach außen vorstehenden Nabe 28 an der Bottichrückwand 15 einseitig drehbar gelagert. Der Stator 29 mit dem Statorblechpaket 30 ist hierbei ringförmig zu der Nabe 28 angeordnet.Reaching the desired noise level can also be supported by providing the inside 17 of the tub rear wall with an insulating layer 19. The drive motor 11 is an external rotor motor, the permanent-magnet rotor designed as an external rotor 23 directly drives the drive shaft 24 of the laundry drum 7. The drive shaft 24 is in this case rotatably mounted on one side in a bearing consisting of two roller bearings 26, 27 in an outwardly projecting hub 28 on the tub rear wall 15. The stator 29 with the stator laminated core 30 is arranged annularly to the hub 28.

Durch die hochpolige Ausbildung des Antriebsmotors 11 bei einer Polzahl > 10 kann der Forderung der Drehzahlbegrenzung, bei der die maximale Motordrehzahl mit der Schleuderdrehzahl identisch ist, wirkungsvoll entsprochen werden. Der Antriebsmotor 11 kann entweder ein Synchronmotor mit einem Umrichter oder auch ein Reluktanzmotor sein. Die den Antriebsmotor 11 umgebende Dämmhaube 13 besteht aus einem einseitig durch einen Boden 20 geschlossenen Hohlzylinder 21, der den Außenläufer 23 eng umgibt und dessen Öffnungsrand 25 mit der Bottichrückwand 15 fest verbunden ist.Due to the multi-pole design of the drive motor 11 with a number of poles> 10, the requirement of the speed limitation, at which the maximum motor speed is identical to the spin speed, can be effectively met. The drive motor 11 can either be a synchronous motor with a converter or a reluctance motor. The insulating hood 13 surrounding the drive motor 11 consists of a hollow cylinder 21 closed on one side by a base 20, which closely surrounds the outer rotor 23 and whose opening edge 25 is firmly connected to the tub rear wall 15.

Der erfindungsgemäße Waschautomat 1 kann mit Motorbetriebsdrehzahlen von 25 bis 2000 1/min betrieben werden, wobei durch die Geräuschkapselung des Antriebsmotors 11 auch der gewünschte Geräuschpegel einfach und wirkungsvoll erreicht wird.The washing machine 1 according to the invention can be operated at engine operating speeds of 25 to 2000 1 / min, the desired noise level being achieved simply and effectively by encapsulating the noise of the drive motor 11.
