Claims (10)

  1. Appareil domestique (1) comprenant un boîtier (2) soumis à des vibrations, et un amortisseur de vibrations (9) fixé audit boîtier (2) pour réduire les vibrations du boîtier ; l'appareil domestique (1) étant caractérisé en ce que ledit amortisseur de vibrations (9) comprend :
    - un cadre de support (10) fixé de façon rigide au boîtier de l'appareil (2) ;
    - au moins un premier aimant (11, 11' ; 12, 18, 12') ajusté de façon rigide au cadre de support (10),
    et
    - au moins un deuxième aimant (12, 18, 12' ; 11, 11') ajusté de façon coulissante audit cadre de support (10) de sorte à avoir un de ses pôles magnétiques tourné vers l'un des pôles magnétiques du premier aimant (11) pour permettre au champ magnétique dudit deuxième aimant (12, 18, 12' ; 11, 11') d'interagir avec le champ magnétique dudit premier aimant (11, 11' ; 12, 18, 12') ;
    le premier aimant (11, 11' ; 12, 18, 12') ou le deuxième aimant (12, 18, 12' ; 11, 11') étant un électroaimant (12, 12', 18), et l'amortisseur de vibrations (9) comprenant également :
    - un moyen d'alimentation électrique (13) capable d'alimenter la bobine d'induction (17, 20) dudit électroaimant (12, 12', 18) avec un courant alternatif de sorte à créer un mouvement de va-et-vient du deuxième aimant (12, 18, 12' ; 11, 11') le long dudit cadre de support (10), et
    - une unité de commande centrale (15) qui commande le moyen d'alimentation électrique (13) et est capable de déterminer, instant par instant, la fréquence du courant alternatif à fournir à la bobine d'induction (17, 20) dudit électroaimant (12, 12' ; 18) pour produire des vibrations mécaniques presque en opposition de phase par rapport aux vibrations mécaniques du boîtier de l'appareil (2).
  2. Appareil domestique selon la revendication 1, caractérisé en ce qu'il comprend également un moyen de détection (14) capable de déterminer, instant par instant, le spectre d'amplitude et de fréquence des vibrations mécaniques du boîtier de l'appareil (2) ; l'unité centrale de commande (15) étant connectée audit moyen de détection (14) et étant capable de déterminer la fréquence du courant alternatif à fournir à la bobine d'induction (17, 20) dudit électroaimant (12, 12', 18) sur la base du spectre d'amplitude et de fréquence desdites vibrations mécaniques.
  3. Appareil domestique selon l'une quelconque des revendications précédentes, caractérisé en ce que le premier aimant (11, 11' ; 12, 18, 12') ou le deuxième aimant (12, 18, 12' ; 11, 11') qui n'est pas un électroaimant (12, 12', 18) est un aimant permanent (11, 11').
  4. Appareil domestique selon l'une quelconque des revendications précédentes, caractérisé en ce que ledit deuxième aimant (12, 18, 12' ; 11, 11') est capable d'effectuer un mouvement de va-et-vient sur ledit cadre de support (10) le long d'un axe de référence sensiblement horizontal (B).
  5. Appareil domestique selon l'une quelconque des revendications précédentes, caractérisé en ce que ledit amortisseur de vibrations (9) comprend un couple de deuxièmes aimants (12, 18, 12' ; 11, 11') ajustés de manière coulissante audit cadre de support (10) sur des côtés opposés dudit premier aimant (11, 11' ; 12, 18, 12').
  6. Appareil domestique selon la revendication 5, caractérisé en ce que ledit amortisseur de vibrations (9) comprend un couple de premiers aimants (11, 11' ; 12, 18, 12') situés entre lesdits deuxièmes aimants (12, 18, 12' ; 11, 11') ; chacun desdits premiers aimants (11, 11' ; 12, 18, 12') étant tourné vers l'un des deux pôles magnétiques de chaque deuxième aimant (12, 18, 12' ; 11, 11').
  7. Appareil domestique selon l'une quelconque des revendications 1 à 4, caractérisé en ce que ledit amortisseur de vibrations (9) comprend un couple de premiers aimants (11, 11' ; 12, 18, 12') fixés audit cadre de support (10) sur des côtés opposés dudit deuxième aimant (12, 18, 12' ; 11, 11').
  8. Appareil domestique selon l'une quelconque des revendications précédentes, caractérisé en ce que ledit amortisseur de vibrations (9) est fixé à l'intérieur dudit boîtier (2).
  9. Appareil domestique selon l'une quelconque des revendications précédentes, caractérisé en ce qu'il s'agit d'une machine à laver le linge (1).
  10. Appareil domestique selon les revendications 9 et 4, caractérisé en ce que ladite machine à laver (1) comprend un tambour rotatif (5) pour loger le linge à laver, et qui est ajusté de manière rotative à l'intérieur du boîtier (2) autour d'un axe de rotation donné (A) ; l'axe de référence (B) le long duquel le deuxième aimant (12, 18, 12' ; 11, 11') effectue un mouvement de va-et-vient, étant sensiblement perpendiculaire audit axe de rotation (A).
