Definitions

  • the invention is specifically concerned with a drum in which the laundry is to be placed during washing and/or drying operations.
  • the type of drum described above has been in use for many years, however, there are problems with such drums.
  • the apertures in the side wall of the drum even though they may be formed with rounded edge surfaces to avoid presentation of sharp edges to the laundry, are still detrimental to the laundry being washed or dried since damage can be caused by the tendency of the laundry to be pressed into the apertures.
  • the apertures formed by the inter-connected flanges will be substantially at positions of maximum diameter of the drum i.e. the position at which water would otherwise collect in the drum and thus, by providing the apertures in this region, maximum efficiency of water extraction is enhanced.
  • the angle of divergence relative to the central axis of the drum is such that it is large enough to aid separation of individual items of laundry being washed or dried in a drum to prevent "balling" of several items together and generally assists separation of the laundry to improve the washing and drying thereof. Furthermore, the angle of divergence is not too large that would cause "bunching", at each end region, of the items of laundry being washed or dried
  • the drum of the present invention assists greatly in overcoming the problems aforementioned concerned with washing machine drums, the internal surface of the side wall member being generally imperforate will be as smooth as possible to minimise wear on the laundry during a washing or drying operation. Furthermore, the divergent side wall member contributes towards better distribution of clothes in the drum. The positioning of the apertures ensures there is minimum contact between the clothes and the apertures themselves in addition to providing a very convenient and strong assembly of the drum as a whole.
  • the drum of the present invention for rotation about a horizontal or vertical axis or any angle therebetween but is primarily intended for a laundry machine in which the drum is rotated or oscillated about a substantially horizontal axis.
