Description

  

      Mobile,        elektrische        Küchenmaschine       Gegenstand vorliegender Erfindung ist eine mo  bile, elektrische Küchenmaschine mit einem Motor  und einer     Zapfwelle    für auswechselbare Werkzeuge.  



  Die Erfahrungen mit Küchenmaschinen der ge  nannten Art haben gezeigt,     dass    eine Reihe von mit  der     Zapfwelle    solcher Küchenmaschinen     kuppelbaren     Werkzeugen in der Handhabung nicht ungefährlich  sind, was für andere nicht oder weniger     zutrifft.    So  stellen insbesondere     Mixeraggregate    mit Zerkleine  rungsmessern eine nicht unerhebliche Gefahr für die  bedienenden Personen dar, während beispielsweise  Rührbügel oder Schwingbesen weitgehend gefahrlos  gehandhabt werden können.  



  Der vorliegenden     Erfindung    liegt die Aufgabe zu  grunde, eine Küchenmaschine der genannten     Art    zu  schaffen, bei welcher die Gefahr, mit dem betreffen  den Werkzeug in Berührung zu kommen, weitgehend  ausgeschlossen ist, wobei zusätzlich noch Mittel vor  gesehen sein können, diese Sicherungen bei der Ver  wendung von gefahrlosen Küchenwerkzeugen un  wirksam werden zu lassen.  



  Die     erfindungsgemässe    Küchenmaschine ist ge  kennzeichnet durch einen im Motorkreis liegenden  Kippschalter, der so angeordnet ist, dass er den Mo  torkreis unterbricht, wenn der Winkel zwischen der       Zapfwelle    und der Senkrechten einen Grenzwinkel  überschreitet.  



  In der Zeichnung ist eine beispielsweise Ausfüh  rungsform des     Erfindungsgegenstandes    dargestellt,  und zwar zeigen       Fig.    1 einen Schnitt durch den unteren Teil der  Küchenmaschine, mit welcher ein     Mixeraggregat    ge  kuppelt ist;         Fig.    2. einen teilweisen Schnitt durch die gleiche  Küchenmaschine, mit welcher, vermittels einer zwei  ten     Zapfwelle,    ein     Schwingarm    gekuppelt ist und       Fig.    3 ein elektrisches Schema.  



  Bei dem in der Zeichnung     dargestellten    Ausfüh  rungsbeispiel besitzt der im Gehäuse 1 untergebrachte  Motor 2 eine     koaxiale        Zapfwelle    3, mit deren Kupp  lungsstück 4 ein     Mixeraggregat    5 gekuppelt werden  kann. Im elektrischen Kreis des Motors ist ein als  Quecksilberschalter ausgebildeter     Kippschalter    6 ein  gebaut, der durch den durch das Kontaktstück 7     be-          tätigbaren    Kontakt 8 überbrückt ist.

   Die Befestigungs  muffe 9 des     Mixeraggregates    5 besitzt einen Kragen  9a, der derart angeordnet und bemessen äst, dass er,  bei eingesetztem     Mixeraggregat    5 das Kontaktstück 7  nicht     beeinflusst,    so dass der Kontakt 8 offen bleibt  und der Stromkreis des     Küchenmaschinenmotors    2  nur dann geschlossen ist, wenn der     Winkel    der Mo  torachse gegenüber der Senkrechten den     Grenzwin-          kel,        d.h.    denjenigen Winkel nicht überschreitet, bei  welchem der Kippschalter den Stromkreis unterbricht.  



  Soll nun mit einer zweiten, in der Zeichnung  nicht     näher    dargestellten, und mit der ersten einen  den Grenzwinkel überschreitenden Winkel     einschlies-          senden        Zapfwelle    ein ungefährliches Werkzeug, bei  spielsweise ein Schwingarm 10, verbunden werden,  so wird die erste     Zapfwelle    3 durch einen an die Stel  le der Muffe 9 tretenden Deckel 11 überdeckt, des  sen Kragen     lla    höher ist als derjenige (9a) der     An-          schlussmuffe    9 des     Mixeraggregates    5, so dass, bei  eingesetztem Deckel 11, dieser Kragen     lla    als Kon  taktorgan dient,

   das Kontaktstück 7 entgegen der  Wirkung der Feder 12 gegen den Motor 2 zu drückt,  so den Kontakt 8 schliesst und damit den Kippschal  ter 6 kurzschliesst. In dieser Betriebslage ist demzu  folge der Motorkreis     unbekümmert    um den Winkel,      welchen die     Zapfwelle    gegenüber der Senkrechten  einschliesst, geschlossen.  



  Daraus ergibt sich, dass wenn ein Werk  zeug     mit    der ersten     Zapfwelle    gekuppelt ist,  der Antrieb unterbrochen wird, sobald der     Grenz-          winkel,    d. h. ein bestimmter Winkel zwischen  der     Zapfwelle    bzw. dem Werkzeug und der Senk  rechten überschritten ist,     während    dann, wenn ein  Werkzeug durch die zweite     Zapfwelle    angetrieben ist,  diese     Zapfwelle,    bzw. dieses Werkzeug in jede Lage  gebracht werden kann, ohne dass der Antrieb unter  brochen würde.



      Mobile, electric kitchen machine The present invention is a mobile, electric kitchen machine with a motor and a PTO shaft for interchangeable tools.



  Experience with kitchen machines of the type mentioned has shown that a number of tools which can be coupled to the power take-off shaft of such kitchen machines are not without risk, which is not the case or is less true for others. In particular, mixer units with chopping knives represent a not inconsiderable danger for the operating people, while, for example, stirrers or whisks can be handled largely without risk.



  The present invention is based on the object to provide a kitchen appliance of the type mentioned, in which the risk of coming into contact with the tool concerned is largely excluded, with additional means can be seen in front of these fuses in the Ver use of safe kitchen tools ineffective.



  The kitchen machine according to the invention is characterized by a toggle switch located in the motor circuit, which is arranged so that it interrupts the motor circuit when the angle between the power take-off shaft and the vertical exceeds a critical angle.



  In the drawing, an example Ausfüh approximate form of the subject matter of the invention is shown, namely Fig. 1 shows a section through the lower part of the food processor, with which a mixer unit is coupled GE; Fig. 2. A partial section through the same food processor, with which, by means of a two-th PTO, a swing arm is coupled and Fig. 3 shows an electrical scheme.



  In the exemplary embodiment shown in the drawing, the motor 2 housed in the housing 1 has a coaxial PTO shaft 3, with the coupling piece 4 of which a mixer unit 5 can be coupled. A toggle switch 6, designed as a mercury switch, is built into the electrical circuit of the motor and is bridged by the contact 8 that can be actuated by the contact piece 7.

   The fastening sleeve 9 of the mixer unit 5 has a collar 9a, which is arranged and dimensioned in such a way that it does not affect the contact piece 7 when the mixer unit 5 is inserted, so that the contact 8 remains open and the circuit of the kitchen machine motor 2 is only closed if the angle of the motor axis with respect to the vertical is the limit angle, ie does not exceed the angle at which the toggle switch interrupts the circuit.



  If a harmless tool, for example a swing arm 10, is to be connected to a second power take-off shaft (not shown in more detail in the drawing) and the first power take-off shaft that includes an angle exceeding the critical angle, the first power take-off shaft 3 is connected to the position le of the sleeve 9 covered cover 11, whose collar 11a is higher than that (9a) of the connecting sleeve 9 of the mixer unit 5, so that, when the cover 11 is inserted, this collar 11a serves as a contact element,

   to press the contact piece 7 against the action of the spring 12 against the motor 2, so the contact 8 closes and thus the toggle switch 6 short-circuits. In this operating position, the engine circuit is therefore closed, regardless of the angle that the PTO makes with respect to the vertical.



  This means that if a tool is coupled to the first PTO shaft, the drive is interrupted as soon as the limit angle, i.e. H. a certain angle between the PTO shaft or the tool and the perpendicular is exceeded, while when a tool is driven by the second PTO shaft, this PTO shaft or this tool can be brought into any position without the drive being interrupted would.
