  • Patent number: 5500967
    Abstract: A liquid fabric softener or treating liquid dispenser for a washing machine having a parabolic or egg-shaped body portion from which radially extends an annular rim portion. The rim portion rests upon a top surface of an agitator and is held in place thereon by a removable, resiliently press-fit cap. The rim portion has a series of bosses extending upwardly therefrom and a series of notched openings formed therein. The bosses space the cap member from the upper surface of the rim portion. During operation of the washing machine in a spin cycle, treating liquid within the body portion of the dispenser flows upwardly along an inner surface of the cup body, downwardly through the notched openings in the rim portion, and into a holding chamber provided within the hollow interior of the agitator.

  • Patent number: 5309739
    Abstract: A clothes washing machine comprises a water container and a washing tub disposed in the water container to form a space therebetween for containing wash water. A tourmaline ceramic coating is applied to an outer bottom surface of the washing tub or to an inner surface of the water container for reacting with the wash water to form hydroxyl ions therein which reduce surface tension of the water. An ultrasonic vibrator is mounted on the water container across from the coating to generate waves in the water to accelerate the reaction between the coating and wash water. Alternatively, the tourmaline ceramic coating could be applied to an agitator disposed in the washing tub.

  • Patent number: 5044178
    Abstract: A compact rinse aid dispenser that mounts on top of the agitator post and dispenses a rinse aid during the rinse cycle. The rinse aid is held in a conical-shaped cup during the wash/agitate cycle, and then is sprayed out and retained against the inner wall of the housing by centrifugal force during the spin cycle. The rinse aid then drains down through a funnel into the agitator post and out a slot therein when the spinning stops. The dispenser has a lid with a horizontal wall and a cylindrical downwardly extending barrier around the fill hole to prevent rinse aid from being sprayed back out the fill hole as a result of an out-of-balance load that causes the agitator post and dispenser to orbit about the vertical axis. Further, a labyrinth is provided around the drain hole in the funnel to prevent premature draining of rinse aid into the agitator post.

  • Patent number: 4882917
    Abstract: A wash additive combination is provided which is loaded into a washing machine at the start of a wash cycle, and which releases a wash additive, such as a fabric softener, into the rinse solution. The combination comprises a wash additive packet of a foam substrate material having a first and a second stable conformation of differing surface area, and a wash additive deposited thereon. A dispenser is provided for mounting atop a washing machine agitator, and into which the packet may be releasably placed, after arranging the packet in its lesser surface area conformation. The packet is retained by the dispenser during initial phases of the wash cycle, and ejected during the spin phase, whereupon it regains its greater surface area conformation for rapid and complete dispersion of active. Embodiments are provided for dual, sequential release of active in the rinse and the dryer.

  • Patent number: 4328600
    Abstract: An automatic washing machine of the fresh-water, vertical-axis type has a dynamic system which includes a single perforate wash basket arranged to be driven continuously such that its central axis moves in an orbital path about another axis. The basket is restrained from rotating about its central axis when it is moving about the other axis and each point of the basket moves in a circulate path having an effective diameter which is small in relation to the diameter of the basket and having substantially the same excursion as the orbital path of the central axis of the basket. Water and soil removing agent are introduced into the basket during orbital motion and that motion is effective to induce a continuous motion of the fabric article load for washing the load. The machine tub and other working components are placed in the moving system and provide a stable base for the basket.

  • Patent number: 4118957
    Abstract: A compact and shallow rinse agent dispenser is removably assembled upon the top of an agitator in an automatic clothes washing machine for dispensing a liquid product upon completion of a spin cycle of the washing machine. An annular, wave dampening baffle is fixed inwardly adjacent the rim of a receptacle cup in which the liquid product is initially placed. The baffle is vertically slotted and limits splashing of the liquid into a dispensing chamber or through filling ports in the cover of the dispenser during the agitation cycle, prior to spin. The discharge chamber to which liquid is passed during the spin cycle has a number of impeller vanes fitted adjacent radially-inwardly-disposed discharge openings therein to minimize loss of liquid during start-up stages of the spin cycle, when centrifugal forces alone are insufficient to confine the liquid to the outside of the chamber.
