Abstract
A method of disassembling a washing machine is a disassembling method for a washing machine including a reduction-gear unit secured on the outside of a water tub and a dehydration tub disposed in the water tub, and the method includes a release step of applying force, along the axial direction of a rotary shaft, in the direction of separating the reduction-gear unit and the dehydration tub from each other to release connection between the reduction-gear unit and the dehydration tub. This scheme can be employed to provide a method of disassembling a washing machine that can recover resin included in the washing machine at a high recovery ratio.
Claims21
A disassembling method for disassembling a washing machine, the washing machine including:
- a vessel formed of resin and including a water tub;
- a driven unit including a dehydration tub and making a rotational movement in said vessel;
- and
- a drive unit including at least one of a motor and a reduction-gear unit, said drive unit being connected through a coupling rod to said driven unit and disposed on the outside of said vessel, and
- the method comprising a release step of applying force, along the axial direction of said coupling rod, in the direction of separating said drive unit and said driven unit from each other to release the connection between said drive unit and said driven unit, wherein
- said release step is carried out in a state where said coupling rod and said driven unit are secured, and
- in said release step, the force is applied in the direction of separating said drive unit and said driven unit from each other while a bottom of said vessel is pressed in a direction away from said drive unit, and said bottom of said vessel is pressed at a position opposite to a bottom of said driven unit.
A disassembling apparatus for disassembling a washing machine, the washing machine including:
- a vessel formed of resin;
- a driven unit making a rotational movement in said vessel;
- and
- a drive unit connected through a coupling rod to said driven unit and disposed on the outside of said vessel,
- the apparatus comprising separating means for applying force, along the axial direction of said coupling rod, in the direction of separating said drive unit and said driven unit from each other, and
- said separating means including means for stopping one of said vessel or said driven unit and said drive unit and for separating the other from the one, wherein
- said separating means applies the force in the direction of separating said drive unit and said driven unit from each other while a bottom of said vessel is pressed in a direction away from said drive unit, and said bottom of said vessel is pressed at a position opposite to a bottom of said driven unit.
A disassembling apparatus for disassembling a washing machine,
- the washing machine including:
- a vessel formed of resin;
- a driven unit making a rotational movement in said vessel;
- and
- a drive unit connected through a coupling rod to said driven unit and disposed on the outside of said vessel,
- the apparatus comprising separating means for applying force, along the axial direction of said coupling rod, in the direction of separating said drive unit and said driven unit from each other, wherein
- said separating means applies the force in the direction of separating said drive unit and said driven unit from each other while a bottom of said vessel is pressed in a direction away from said drive unit, and said bottom of said vessel is pressed at a position opposite to a bottom of said driven unit, and
- said separating means is formed to apply said force of at most 940 kg.
