## Abstract

An apparatus is disclosed for treating laundry, including a cabinet having a top surface providing a space for seating an object therein, a front surface provided with a first perforated hole and a second perforated hole and a top surface perforated hole configured to perforating the top surface, a drawer drawable from the cabinet through the first perforated hole, a drum rotatably provided within the drawer to provide a space for storing the laundry therein, a slide exposed to the front surface of the cabinet through the second perforated hole to maintain a state that the drawer is drawn from the cabinet in a preset reference distance, and a transfer part exposed to the top surface of the cabinet through the top surface perforated hole so as to move the slide into the cabinet if an object is seated on the top surface.

## Claims

### Claim 1

An apparatus for treating laundry, comprising:
a cabinet having a top surface providing a space for seating an object therein, a front surface provided with a first perforated hole and a second perforated hole and a top surface perforated hole configured to perforating the top surface;
a drawer drawable from the cabinet through the first perforated hole;
a drum rotatably provided within the drawer to provide a space for storing the laundry therein;
a slide exposed to the front surface of the cabinet through the second perforated hole to maintain a state that the drawer is drawn from the cabinet in a preset reference distance; and
a transfer part exposed to the top surface of the cabinet through the top surface perforated hole so as to move the slide into the cabinet if an object is seated on the top surface.

### Claim 2 (depends on 2)

The apparatus of claim 2, further comprising:
a drum drive unit revolving the drum;
a magnet provided to one of the drawer and the cabinet;
a magnetic force detecting unit provided to the other one of the drawer and the cabinet to detect a magnetic force of the magnet; and
a controller activating the drum drive unit only if the magnetic force detecting unit detects the magnetic force of the magnet.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the reference distance is set to a distance for the magnetic force detecting unit not to detect the magnetic force of the magnet.

### Claim 4 (depends on 2)

The apparatus of claim 2, further comprising:
a drum drive unit revolving the drum;
a magnet provided to one of the drawer and the cabinet;
a magnetic force detecting unit provided to the other one of the drawer and the cabinet to detect a magnetic force of the magnet; and
a controller activating the drum drive unit only if the magnetic force detecting unit detects the magnetic force equal to or greater than a preset reference value.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the reference distance is set to a distance enough for the magnetic force detecting unit to detect the magnetic force smaller than the reference value.

### Claim 6 (depends on 1)

The apparatus of claim 1, the transfer part comprising:
a transfer body having one end exposed to the top surface of the cabinet by perforating the top surface perforated hole and the other end located within the cabinet;
a transfer projection provided to the transfer body; and
a transfer recess provided to the slide to provide a space for receiving the transfer projection therein so as to move the slide to an inside of the cabinet if the transfer projection moves toward the inside of the cabinet.

### Claim 7 (depends on 6)

The apparatus of claim 6, the slide comprising:
a sliding body located within the cabinet and provided with the transfer recess; and
a support body having one end fixed to the sliding body and the other end exposed to a front surface of the second cabinet through the second perforated hole.

### Claim 8 (depends on 7)

The apparatus of claim 7, further comprising:
a housing fixed to the cabinet and providing a space for receiving the sliding body therein;
a first housing perforated hole configured to perforate a surface facing the front surface of the cabinet in the space provided by the housing so as to have the support body inserted therein;
a second housing perforated hole configured to perforate a surface facing the top surface of the cabinet in the space provided by the housing so as to have the transfer body inserted therein;
a fastening part provided to the sliding body; and
a guide provided to the housing along a moving direction of the sliding body to provide a moving path of the fastening part.

### Claim 9 (depends on 8)

The apparatus of claim 8, further comprising:
a projection provided to one of the housing and the transfer body; and
a projection receiving recess provided to the other one of the housing and the transfer body along a direction side by side with a moving direction of the transfer body to provide a moving path of the projection.

### Claim 10 (depends on 8)

The apparatus of claim 8, the object comprising:
a second cabinet seated on the top surface of the cabinet;
a second entrance provided to the second cabinet; and
a second drum rotatably provided within the second cabinet to provide a space for storing laundry supplied through the second entrance therein.

### Claim 11 (depends on 10)

The apparatus of claim 10, further comprising:
a first connecting body projected from the second cabinet toward the top surface of the cabinet and pressurizing the transfer body into the cabinet if the second cabinet is seated on the top surface of the cabinet;
a second connecting body projected from the top surface of the cabinet toward the second cabinet; and
a fastening member coupling the first connecting body and the second connecting body to each other.

### Claim 12 (depends on 11)

The apparatus of claim 11, further comprising:
a leg projected from the second cabinet toward the top surface of the cabinet;
a bracket provided to the top surface of the cabinet to provide a space for receiving a bottom surface of the leg therein, the bracket provided with the second connecting body; and
a bracket perforated hole located above the top surface perforated hole by perforating the bracket so as to have the transfer body inserted therein.
