Definitions

  • Conventional drum type automatic washing machines include a perforated cylindrical drum mounted for rotation about a horizontal axis within a fixed, closed water tank. Garments or other items to be washed are placed in the rotatable cylindrical drum, typically through a front opening door to the drum, or alternatively through an opening in the side wall of the drum. In either case, the opening of the drum is closed, and the water tank closed.
  • Water is introduced into the water tank, filling the tank to a predetermined level.
  • the water may be heated either before filling the tank, within the tank by a heater or may be removed from the water tank and heated before being reintroduced into the tank.
  • the water within the water tank enters the cylindrical drum through the perforations in the cylindrical drum or through the shaft.
  • the cylindrical drum is then rotated about its axis to agitate the items to be washed and to pass these through the washing water.
  • the washing water is removed from the water tank, and hence from the cylindrical drum via an outlet.
  • the outlet is typically in the form of a valve which allows water to drain from the water tank by gravity, or is a pump. Clean water for rinsing is then introduced to the water tank and hence into the cylindrical drum. The drum is again rotated to agitate the items within the drum. The rinsing water is then removed from the water tank in the same way as the washing water.
  • DE-B-1017128 discloses a washing machine having a fixed water tank which is inclined to the horizontal. The front opening of the water tank is sealing closed.
  • the tank contains a rotatable clothes containing drum.
  • the rear face of the rotatable drum includes a central drawing chamber including apertures for communication with the inside of the rotatable drum.
  • Water is introduced into the fixed water tank. When the water level in the tank reaches the level of the opening to the drum, the water enters the drum. When the water level in the rotatable drum reaches the level of the apertures, the water flows into the drawing chamber and is expelled along the hollow shaft on which the drum is mounted.
  • washing machines As with other household appliances, are generally manufactured to a standard size to fit into a standard size space below and between kitchen units. Accordingly, it is desirable that the overall size of the washing machine should remain the same as conventional washing machines.
  • the size of the cylindrical drum which receives the items to be washed cannot be increased significantly without increasing the size of the water tank in which the drum is provided.
  • the water tank cannot be enlarged without increasing the overall size of the machine, and it is therefore not possible to increase the capacity of a conventional washing machine whilst keeping the overall machine size unchanged.
  • a problem with single drum washing machines is that, unlike conventional machines with a fixed water tank, it is difficult to provide heaters, water level detectors and water outlets below the water level in the rotatable water tank, firstly due to the difficulty in making a physical or electrical connection between the fixed body of the machine and the rotating drum, and secondly as a water outlet, heater or detector fixed on a rotating drum will rotate with the drum and hence move above the level of the water as the drum is rotated unless the outlet, heater or detector is provided axially. Even where the outlet is provided axially, the outlet, heater or detector will usually be above the height of the water.
  • the single drum is provided with an inclined side wall having a larger diameter at the back end than at the open front end.
  • the drum is rotated at a high speed forcing water within the drum, by centrifugal force, to the side walls of the drum and, due to the inclined sides, towards the rear of the drum.
  • a fixed wiper blade is mounted on the axle of the drum, which does not rotate, the wiper abutting the rear of the side wall of the drum. As water is forced to the rear of the side wall, the water is wiped from the side wall by the wiper, and runs down the wiper blade to a centrally located outlet.
  • Such high speed rotation is disadvantageous as water can only be removed when the drum is rotated at high speed, it is not possible to remove water during a wash cycle, and it is therefore not possible to recirculate and reheat the water.
  • Washing machines are used not only for washing items of clothing, but may also be used for dying of garments.
  • the washing water is replaced by a suitable dye, but in other respects the washing cycle is unchanged.
  • a washing machine comprises a generally cylindrical drum having a substantially closed back face, a front opening, and an axis inclined to the horizontal about which the drum is rotatable, wherein the drum includes a plurality of outlets provided on the back face of the drum generally around the circumference of the back face, at least one of which outlets is below the height of the front opening for any angular position of the drum, and a water collector for collecting water discharged through the outlets, and from which the collected water is dispensed through a fixed outlet.
  • Having a plurality of holes arranged around the circumference ensures that any water on the side of the drum, for example water forced to the side of the drum by centrifugal force during spinning, and water flowing down the side wall of the drum under gravity due to the inclination of the drum, will drain through the holes.
  • the drum is seated in a fixed collector having a circular or annular recess corresponding to the outlets of the drum.
  • a fixed outlet is provided at the lowermost point of the recess.
  • the exterior back end of the drum may include a pair of annular walls together defining an annular collector containing each of the water outlets, the annular walls fitting within an annular groove in a fixed housing of the machine, the annular groove having at least one water outlet point.
  • the annular walls on the back end of the drum rotate coaxially within the annular groove in the fixed housing. Water dispensed through the outlets in the back of the drum is contained between the annular walls and within the groove, and is dispensed through the water outlet point in the groove. Accordingly, this arrangement acts as a seal to prevent leakage of water where the outlets are not provided on the axis of the drum, yet allows rotation of the drum, despite the vibrations which occur during rotation.
  • a splash-proof closure is provided over the front opening of the drum. This prevents water splashing out of the front opening of the drum during the washing and rinsing cycles, and stops items being washed from falling out.
  • the axis of the rotating drum is preferably inclined at an angle of between 5° and 45°.
  • the side wall of the drum may be tapered with the circumference near the front of the drum being less than the circumference towards the back of the drum. This ensures that the water in the drum descends towards the collectors due to centrifugal forces, especially at high rotation speeds.
  • a divider is provided in front of the outlets.
  • the divider extends substantially, but not completely, over the back end of the drum. As the divider does not extend over the entire back end of the drum, water can still pass through the divider to be discharged from the drum, however items being washed cannot pass through the divider and become entangled in the outlets.
  • the divider is preferably formed with apertures provided around the circumference which abuts the side walls of the drum through which the water can pass, or can be formed with perforations through which the water can pass.
  • the washing machine may include a pair of raised projections, each projection extending substantially from the back of the drum to the front of the drum, one of the projections extending generally clockwise from the rear of the drum to the front of the drum, and the other extending generally anti-clockwise from the rear of the drum to the front of the drum, so that in use, items provided within the drum are lifted and drawn towards the front of the drum by rotation of the drum in either direction.
  • a plurality of projections are provided extending in both clockwise and anti-clockwise directions to improve the agitation of the garments further.
  • the projections preferably extend in a generally helical direction around the inner circumference of the rotating drum.
  • the washing machine preferably includes a heater for heating water added to the drum and rotatable with the drum.
  • the heater is provided in a recirculation path between the water outlet and the water inlet. In this way, during the normal wash cycle water can be removed from the drum through the water outlets, reheated and resupplied to the drum through the inlet thereby maintaining the water at a constant temperature.
  • the washing machine may include a perforated container provided within the rotating drum and closely abutting the inner surface of the drum. In this way, the items to be washed can be placed in the perforated container, and after completion of the washing cycle the perforated container can be removed from the drum together with all the washed items. As the perforated container closely fits the side wall of the drum, the capacity of the washing machine is not reduced significantly by the provision of the perforated container. The use of a perforated container allows for easy unloading of the drum.
  • agitators these may be provided within the perforated container rather than, or in addition to, being provided in the drum itself.
  • the washing machine includes a water level detector to determine the volume of water in the drum.
  • the recirculation path may include a chamber open to the atmosphere, a pressure sensor downstream of or below the water surface in the chamber and a means for determining the volume of free water in the rotatable drum from the pressure.
  • the amount of water can be determined, and therefore water can be supplied to the machine to saturate the clothes and give a predetermined volume of free water irrespective of the amount of absorbed water by cutting off the supply when the predetermined volume of free water is detected.
  • the water expelled from the rotatable drum is introduced to the open chamber from which the recirculation path returns to the rotatable drum.
  • the chamber is open, it is at atmospheric pressure, and so the detected pressure is not affected by pressure fluctuations which may occur in a closed system.
  • the volume of water can be calculated from the detected pressure.
  • the recirculation path advantageously includes a pump to recirculate the water, and may include a heater to reheat the water to a required temperature.
  • the machine may be used for purposes other than washing items, for example for dying items, in which case the washing water is replaced by a suitable dye.
  • Figure 1 shows a cross-sectional view taken through the axis of a generally cylindrical drum of a washing machine according to the present invention.
  • the cylindrical drum includes a side wall 1 and a circular back end wall 7 defining a drum with an open front 8.
  • the drum is mounted on an axial spindle 2 for rotation about its axis which is inclined to the horizontal at an angle of about 20°.
  • the back surface 7 of the drum includes a plurality of outlet holes 5. The lowest outlet hole 5 at any angular position of the drum is below the vertical height of the lowest part of the lip defining of the front opening 8.
  • the drum also includes a removable perforated container 3 which is positionable within the drum through the front opening 8 of the drum, and which is removable through the front opening 8.
  • the perforated container 3 is shaped and dimensioned to correspond closely to the internal walls of the drum so the internal volume of the perforated container 3 is only slightly smaller than that of the drum.
  • the perforated container 3 is generally tapered so that the front end including the opening has a larger diameter than the rear closed end. This assists in the insertion of the perforated container 3 into the drum.
  • the perforated container 3 has perforations through which water in the drum can pass into the perforated container 3, and through which water in the perforated container 3 can drain into the drum.
  • the perforated container 3 is held within the drum in such a way that the perforated container 3 rotates with the drum.
  • This is achieved by a projection 9 provided on the drum which engages with a recess 10 on the perforated container 3.
  • the projection 9 and recess 10 are provided axially, the projection 9 and recess 10 have a non-circular shape to transmit the rotation of the drum to the perforated container 3.
  • the projection 9 and recess 10 may be provided non-axially, and in this case the projection 9 and recess 10 can have any desired shape.
  • the projection may be provided on the perforated container 3 and the recess on the drum, or, where there is more than one projection and recess, a mixture of recesses and projections may be provided on both the drum and the perforated container 3.
  • the open end of the perforated container 3 includes an annular ring 4 giving a reduced diameter opening to the perforated container 3.
  • the ring 4 ensures that clothes do not fall out of the perforated container 3 during the washing cycle.
  • the perforated container 3 includes a hinged portion extending along the side of the perforated container 3 generally parallel to the longitudinal axis of the perforated container 3.
  • the perforated container 3 also includes a clasp to hold the perforated container 3 in its generally cylindrical shape.
  • a clasp may be undone and the perforated container opened about the hinge to allow easy access to the contents of the perforated container.
  • An alternative example of a perforated container is shown, in a drum, in Figure 3.
  • the perforated container includes a completely closed front end, and an opening 25 in the side wall. As the side wall corresponds closely with the inside of the drum, items contained within the perforated container are not able to fall from the perforated container through the opening into the drum. With this arrangement, items to be washed are added to the perforated container through the opening 25 before the perforated container is placed in the drum. When full, the perforated container is lifted into the drum, effectively closing the perforated container so all the items to be washed are maintained within the perforated container.
  • a shroud 6, inclined to the horizontal at the same angle as the drum is provided to a vertical front opening of the machine.
  • the opening of the machine is closed by a door 11.
  • This closure does not form a watertight seal but acts merely to prevent splashes during the washing cycle.
  • clothes are placed into the perforated container 3, either before the filled perforated container 3 is put in the cylindrical drum through the front opening 8, or when the perforated container 3 has been positioned in the drum.
  • Water, which may include washing detergent is introduced to the drum through the spindle 2. The water enters the perforated container 3 through the perforations in the perforated container to wet the clothes.
  • the rear 7 of the drum is positioned within a recess of a water collector 12 which is fixed on the suspension of the machine. As water is discharged through the holes 5 in the back of the drum, this will be collected in the water collector 12, and will fall, under gravity, to the bottom of the water collector to be dispensed through the outlet 13.
  • the rate at which the water is discharged from the drum is such that there is no need to provide a hermatic seal between the edge of the water collector 12 and the outside of the drum.
  • the water may be recirculated, and may pass through a heater (not shown) to reheat the water, before being reintroduced to the drum through the inlet 2. This ensures that the water within the drum is maintained at the required temperature.
  • FIG. 4 shows a schematic view of a water volume detector which is provided in the recirculation path to determine the volume of the free water in the drum.
  • the volume of water in the tank can be determined by measuring the pressure difference in part of the recycling circuit.
  • the water in the fixed tank is pumped from the tank, around a recycling path and back into the fixed tank.
  • a pressure sensor provided between the tank and the pump detects the pressure due to the head of water in the tank, and from this the volume of water can be calculated from the measured pressure.
  • the pressure in the drum is at atmospheric pressure as the drum is not perfectly sealed.
  • a system is provided to ensure that sufficient water is added to the drum to saturate the items to be washed completely.
  • Water from an external source is added to a secondary chamber 14 which is open to the atmosphere.
  • the water is pumped from the secondary chamber 14 into the main drum.
  • Water discharged from the drum is introduced into the secondary chamber 14.
  • a pressure detector 15 is provided between the secondary chamber 14 and the pump 16, and by measuring the pressure it is possible to determine the volume of water in the chamber 14.
  • the secondary chamber 14 is open to the atmosphere, so the detected pressure is purely due to the head of water in the secondary chamber 14. If the secondary chamber 14 were closed, the pressure in the tank may vary as the volume of water compresses the air in the tank.
  • the water entering the secondary chamber 14 from the external source is pumped into the drum and is absorbed by items in the drum. No or little water will be discharged from the drum. When the items in the drum are completely saturated, additional water will be discharged from the drum into the secondary chamber 14. This additional water will change the rate of change of the volume of water in the secondary chamber 14, or the water in the secondary chamber will reach a predetermined volume. This is detected by the pressure sensor. When it is determined that sufficient water has been provided to the drum, the external supply can be cut off.
  • the rear of the drum 7 may be provided with two annular rings 20 and 21 defining a channel 22 containing the outlet orifices 5.
  • the housing of the washing machine similarly includes two annular walls 23,24 to define a groove 25, the width of the groove 25 being such that the walls 20 and 21 on the back of the drum 7 are provided within the groove 25.
  • the groove 25 includes a single outlet 26, although additional outlets may be provided.
  • the drum or perforated container 3 may be provided with agitators to lift the clothes within the drum.
  • agitators are in the form of a projection 30 which extends from the back of the drum 7 circumferentially around the drum and towards the front of the drum and returns to the back of the drum.
  • the base of the agitator 30 is generally triangular in cross-section, having a maximum height from the side wall 1 near the base 7 of the drum, and a minimum height near the front 8 of the drum.
  • the cross-sectional shape of the agitator 30 may be other than triangular.
  • the agitator 30 has rounded apexes to prevent damage to the clothes.
  • the perforated container 3 is provided with corresponding agitators. In this case the agitators act to hold the perforated container within the drum to prevent relative rotational movement of the drum and perforated container 3 during the washing cycle.
  • only one agitator 30 is shown, two or more agitators may be included. Because the agitator 30 includes components extending towards the front of the drum in both a clockwise and anti-clockwise circumferential direction, on rotation of the drum, articles within the drum are lifted and drawn towards the front of the drum upon rotation of the drum in either direction.
