APARATO DOMESTICO, TAL COMO UNA BATIDORA, EQUIPADO CON UN DISPOSITIVO DE SEGURIDAD

EL INVENTO SE REFIERE A UN APARATO DOMESTICO, QUE COMPRENDE UN CARTER (1) QUE PRESENTA UN ASIENTO ANULAR (2) DE RECEPCION DE UN BOL DESMONTABLE (3), Y QUE ENCIERRA UN MOTOR (4) CUYO ARBOL DE SALIDA (5) SOBRESALE DE DICHO ASIENTO, EL BOL TIENE UN FONDO DESMONTABLE CONSTITUIDO POR UNA BASE (6) QUE LLEVA UNA HERRAMIENTA ROTATIVA ADAPTADA PAR ACOPLARSE CON EL ARBOL (5) DEL MOTOR. SEGUN EL INVENTO, LA BASE (6) COMPORTA AL MENOS UNA TRABA (16) QUE ESTA MONTADA DE MODO MOVIL A TRAVES DE LA PARED (12) DE DICHA BASE ENTRE UNA POSICION ESCAMOTEADA PARA LA CUAL PERMITE EL ENSAMBLADO DE LA BASE SOBRE SU ASIENTO (2) Y POR CONSIGUIENTE EL ACOPLAMIENTO DE LA HERRAMIENTA CON EL ARBOL (5) Y EN LA CUAL ESTA INDUCIDA POR LA FIJACION CORRECTA DEL BOL (3) SOBRE LA BASE Y UNA POSICION SALIENTE PARA LA CUAL SE EXTIENDE LATERALMENTE EN LA BASE Y LLEGA A TOPAR CON LA REGION SUPERIOR (17) DEL ASIENTO (2) DE MODO QUE IMPIDA EL ACOPLAMIENTO DE LA HERRAMIENTA (7) CON EL ARBOL (5) DEL MOTOR CUANDO EL BOL NO ESTA PRESENTE SOBRE LA BASE. EL INVENTO SE APLICA SOBRE TODO A LAS BATIDORAS DOMESTICAS. The invention relates to a household appliance, comprising a casing (1) with an annular seat (2) for receiving a removable bowl (3), and which contains a motor (4) whose output shaft (5) projects from the said seat, the said bowl having a removable bottom consisting of a base (6) which carries a rotary tool designed to couple with the shaft (5) of the motor. According to the invention, the base (6) includes at least one blocking member (16) which is mounted to be movable through the wall (12) of the said base between a retracted position in which it allows the base to be fitted onto its seat (2) and therefore the tool to be coupled with the shaft (5), and into which position is brought by correct attachment of the bowl (3) onto the base, and a projecting position in which it extends laterally to the base and engages with the upper region (17) of the seat (2), so as to prevent the tool (7) being coupled with the shaft (5) of the motor when the bowl is not present on the base. The invention applies more particularly to household mixers.
