Definitions

  • the washing machine in accordance with the present invention comprises a tank adapted to contain a mass of water.
  • Agitator means is located in a central portion of the tank and is received in a casing having a cylindrical portion surrounding the periphery of the agitator.
  • the agitator means and the associated casing cooperate to produce in the mass of water a plurality of currents, namely (1) a current generated by centrifugal action of the agitator and directed approximately at right angles to the axis of rotation of the agitator, (2) a current produced by blades on the rear face of the agitator and directed by the cylindrical portion of said casing to flow in a direction approximately parallel to the axis of the rotor and, hence, approximately perpendicular to the first current and (3) a current induced by the action of the second current and flowing in a space im- 2,955,451 I Patented Oct.
  • the shaft 4' may be carried by ball bearings 14 and 15 arranged insidea casing 16 to which the basket17 is attached.
  • the casing 16 is itself mounted for rotation with the, basket 17, owing to the ball bearings 18 and 19 mediately outside the cylindrical portion of the casing in a direction approximately parallel to that of the second current.
  • the current thus induced augments the action of the other currents, all of which act conjointly to produce a swirling movement in the water filling the tank of the washing machine so as to agitate the linen therein and produce an effective and efficient washing action.
  • a rotatable perforate basket is provided inside the tank of the washing machine and the agitator and associated casing are located in a central portion of the basket. Means is provided for rotating the basket and the agitator independently of one another.
  • Figure 1 is a View in section of the machine.
  • Figure 2 is a view, on a larger scale, of the control mechanism for the stirring element itself and for the casing which surrounds it and illustrates a modification.
  • the washing machine represented in Figure 1 comprises a tank 1, closed by a lid 2. Inside that tank and about one third of the distance separating its two lateral walls there is a stirring element 3 capable of being driven in rotation, with its axle 4, through the pulley 5. This axle is protected by a housing 6 which flares out at its front part 7 so as to comprise a substantially cylindrical portion 8 surrounding closely the stirring element 3 and terminating in a free lip portion 8a.
  • Said stirring element comprises paddles 9 on its front face, and paddles 10 on its rear face; said paddles may, if desired, be symmetrical.
  • the front paddles 8 cause centrifugal currents F in a manner known per se.
  • the rear paddles 10 suck in the liquid contained in the rear portion of the tank, along the arrow F a portion of which F goes through the perforations 11 provided to that efiect in the portions 6 and 7 of the housing, while another portion follows said on one side, 20 and 21 on the other side, owing to which the machine allows not only the washing but also the drying of the clothes. Sealing joints 25 and 26 protect said bearings.
  • the driving in rotation of the basket 17 may be ob tained by a pulley 22 on a shaft 23 arranged on the side opposite the pulley 5 and the shaft 4 driving the stirring element 3 as illustrated in Fig. l.
  • the drive may also be entirely on the same side by a pulley '24 keyed on the casing 16 to drive the basket as illustrated in Fig. 2.
  • the basket 17 has, preferably, a circular cross section concentric with the shafts 4 and 23. l
  • a washing machine comprising a tank adapted to contain a mass of water, a relatively long substantially horizontal shaft extending through one of the walls of said tank, means rotatably driving said shaft, a discshaped agitator secured on the inner end of said shaft and spaced a substantial distance inwardly from said wall, a casing coaxial with said shaft and comprising a constricted portion surrounding said shaft rearwardly of said agitator, an intermediate portion flaring radially outwardly-from said constricted portion and enveloping the rear of said agitator and a cylindrical portion surrounding the periphery of said agitator and terminating in a substantially cylindrical free lip portion, a rear portion of said casing being perforated and said cylindrical portion being spaced radiaHy outwardly from the periphery of said agitator and being immediately surrounded by a free space for flow of Water in an axial direction both inside and outside said lip, said agitator comprising a disc plate, a plurality of blades on the front face of said disc adapted to
