Abstract

An apparatus comprising an outer casing with a base, at least one side wall, and a top, within which are located a drum, typically with a curved side wall and first and second end walls, an agitator and a liquid retainer. The liquid retainer and a side wall having aligned ports through which an end portion of the drum may reversibly travel between a first retracted position and a second extended position. The travel of the drum out of the side wall to the extended position allows access to at least one aperture in the curved side wall of the drum.

Claims

1. Laundry apparatus comprising an outer casing with a base, at least one side wall, and a top, within which are located a receptacle for receiving items to be laundered, an arrangement for agitation of said items, a liquid retention device at least partially surrounding said receptacle, and a control system;

wherein said receptacle is a single-piece drum having opposing first and second end walls with a substantially fully curved side wall therebetween, the liquid retention device and a side wall of the apparatus are provided with aligned ports through which an end portion of the drum may reversibly travel between a retracted position and an extended position, distance of travel of the drum out of the side wall to the extended position being sufficient to allow access to at least one aperture provided in the curved side wall of the drum, said curved side wall of said drum being substantially parallel to the direction of travel of the drum, said aperture being configured and dimensioned to allow insertion and removal of items to be laundered, and the direction of travel of the drum being substantially parallel to the longitudinal axis of the drum.

2. Laundry apparatus according to claim 1 in which the drum is comprised of a curved wall and a first and second end wall, a portion of at least one of the walls being adapted to allow the passage of liquid through that portion of the wall.

3. Laundry apparatus according to claim 2 in which a portion of at least one of the walls of the drum is formed from netting, wire mesh, perforated metal sheet, or metal sheet provided with apertures.

4. Laundry apparatus according to claim 1 in which the drum is substantially cylindrical.

5. Laundry apparatus according to claim 1 in which one or both of the drum and the alined ports are configured so that a portion of the drum can only travel through the alined ports when the drum has a predetermined orientation relative to the outer casing.

6. Laundry apparatus according to claim 5 in which the predetermined orientation is one in which the aperture in the drum is in the portion of the drum closest to the top of the outer casing.

7. Laundry apparatus according to claim 1 in which the drum may rotate about an axis substantially parallel to the direction of travel of the drum when the drum is in the extended position.

8. Laundry apparatus according to claim 1 in which at least one aperture in the drum is provided with a means to close that aperture when the drum is in the withdrawn position.

9. Laundry apparatus according to claim 8 in which the or each aperture closure means is actuated by the drum travelling between the withdrawn and extended positions.

10. Laundry apparatus according to claim 1 in which the apparatus is a washing machine, a tumble dryer, or a combined washing machine and tumble dryer.
