Definitions

  • FIG. 1 A first figure.
  • This invention relates to washing machines and in particular machines wherein clothes are hung upon racks or rods within a cabinet wherein they are automatically washed, rinsed, and dryed while in a suspended state. With certain types of such machine it is possible to arrange the hanging of the clothes or other articles to be washed together with the washing and drying parts of the operating cycle so that the articles end up in a usable condition without requiring ironing.
  • the present invention affords a very compact and simple washing and drying system serving a variety of functions.
  • four separate motors have been incorporated in order to drive a circulation pump, a drain pump, a cross flow fan to draw air through the condenser duct and a geared motor drive in order to vary the flow of air within the compartment during drying.
  • the arrangement of the present application reduces the number of motors to one which in itself produces a very considerable cost saving and at the same time enables a very compact arrangement to be provided for the drive of the circulation and drain pump together with the fan for circulating air through the condenser duct which has enabled the overall height of the construction to be reduced or alternatively for a larger compartment to be included within the same height.
  • the proposals for alternating the flow of liquid between the top and bottom spray bars as compared with prior proposals wherein both spray bars are operated at the same time, albiet intermittently, enables the entire pump output to be directed to one spray bar at a time.
  • the required pump flow can be reduced by half as a result of which the motive power required for the circulation pump drive can be halved while maintaining maximum spraying time consistent with water quantity used and avoiding the loss of energy due to possible interference between the top and bottom sprays meeting when operating simultaneously.
  • the circulation pump may be run on a 6 seconds on and 6 seconds off repeating cycle with the pump output being fed alternately to the top and bottom spray bar. Drain back to the sump of washing or rinsing liquid from the clothes load occurs during the 6 seconds of period.
  • the invention is concerned with certain aspects of washing machines of the type where garments are vertically hung, these aspects including the manner in which washing or rinsing fluid is supplied to the clothes,
  • the invention is of specific but not exclusive application to arrangements in which the sprays are of a rotary, and e.g. self-propelled jet reaction type.
  • the fluid distribution system incorporates alternating fluid flow to the upper and lower sprays.
  • One preferred form of such system is specifically taught in copending application U.S. Ser. No. 244,829, now abandoned, in which a bistable ball valve is used in conjunction with a single intermittently driven pump.
  • Other types of valves such as solenoid-controlled, could be used.
  • dual pumps or reversible pumps could be used with the present invention.
  • a washing machine includes a cabinet having a washing compartment within which articles to be washed may be suspended therein to be acted upon by water directed from a spray during washing and rinsing and to a drying air flow during a drying operation.
  • the spray is provided by a rotary spray bar carried by a shaft, the spray bar shaft being adapted to be driven by a motor in one direction of rotation of the motor but not in the other direction of rotation of the motor.
  • the motor also is adapted to drive a circulation pump having an inlet communicating with the lower end of the washing compartment and an outlet communicating with the spray bar.
  • the circulation pump may be mounted on a pump shaft which also carries a drain pump having an inlet which also communicates with the lower end of the washing compartment. The drain pump is operative in one direction of rotation of the pump shaft while the circulation pump is inoperative, and the drain pump is inoperative in the other direction of rotation of the pump shaft while the circulation pump is operative in that direction of rotation.
  • air may be circulated within the washing compartment by means of a fan which is also carried by the spray bar shaft and which may for example be integrally formed with the spray bar.
  • the spray bar may be formed separately from the positively driven fan, but freely rotatable around the same axis.
  • a protective grill may be disposed above the fan blades, but below the spray bar to avoid impeding upward flow of liquid from the spray bar.
  • FIG. 1 is a diagrammatic side view in section of a washing machine according to the present invention
  • FIG. 2 is an enlarged view of the upper and lower portions of the washing machine of FIG. 1;
  • FIG. 3 is a sectional view taken along lines 3-3 of FIG. 2 showing the lower spray bar and fan assembly;
  • FIG. 4 is a sectional view taken along lines 4-4 of FIG. 1 showing the upper spray arm and air distribution assembly
  • FIG. 5 is a sectional view taken along lines 5-5 of FIG. 2;
  • FIG. 6 is a sectional view taken along lines 66 of FIG. 4;
  • FIG. 7 illustrates a modified form of an integral spray bar and fan arrangement
  • FIG. 8 is an end view, partly broken away, of the fan and spray bar of FIG. 7;
  • FIG. 9 is a side view in section of the washing machine showing an alternative spray bar and fan configuration
  • FIG. 10 is a sectional view taken along lines 10-10 of FIG. 9 showing the construction of the fan hub of FIG. 9.
  • FIGS. 1 and 2 a cabinet 10 is generally shown within which is formed a washing compartment 11 wherein articles to be washed such as clothes can be hung from horizontal carriers or bars situated at the upper end of the compartment.
  • articles to be treated are subjected to downwardly and upwardly directed sprays from a pair of spray bar assemblies 12 and 13 respectively.
  • Each of these spray bars is mounted for rotation about a vertical axis, the spray bar 12 being situated at the top of the compartment 11 and the spray bar 13 at the bottom of the compartment beneath a wire guard 14.
  • Each of the spray bars is adapted to be driven by self propulsion when supplied with water under pressure and for this purpose each spray bar incorporates a number of tangentially extending spray jets.
  • the spray bars are supplied by means of a water recirculation system extending from the outlet of a circulation pump 21 which is mounted on a vertical pump shaft 22 adapted to be driven via a belt 23 by a motor 24 situated below the compartment 11.
  • the pump 21 draws wash and rinse water from a sump 28 which also includes a water heater 29 and filter screen 25.
  • the pump shaft 22 also carries a drain pump 26 having an inlet 27 communicating with the sump 28 to which liquid draining from articles to be washed can flow.
  • the pump has an outlet 30 extending to a drain hose 31.
  • the motor 24 is of reversible type and is arranged in one direction of rotation to drive the drain pump 26 in an operative manner to drain the compartment 11 while in the other direction of rotation the drain pump is ineffective.
  • the circulation pump 21 is arranged to be operative when the drain pump 26 is ineffective and vice versa.
  • liquid will be directed through the outlet of the pump and passed to the fluid distribution system, including a bistable valve described in detail in copending application U.S. Ser. No. 244,829, now abandoned.
  • the bistable valve will provide alternating fluid flow through conduits 33 and 34 to the upper and lower spray bars respectively.
  • the lower spray bar 13 at this time will not be driven positively, but is free wheeling. Nevertheless, the jets of liquid leaving the spray bars are sufficient to cause them to rotate.
  • a one-way clutch 40 above the circulation pump 21 is adapted to drive the lower spray bar assembly through fan shaft 44 at the speed of rotation of the pump shaft 22.
  • fan blades 45 Shown in FIGS. 3 and 5) which have little or no effect when the lower spray bar 13 is being driven at relatively slow speed by the water jets extending therefrom during recirculation.
  • these fan blades 45 during high speed operation are adapted, when the water level in the sump 28 is low enough, to draw air downwardly from within the compartment 11 and direct this air flow into a fan outlet 46 which communicates with a vertically extending passage 47 extending up the side of the compartment 11 and communicating at its upper end with a central chamber 48. If desired, the passage 47 (or more than one such passage) could extend up in the corner or corners of the compartment.
  • the upper spray bar assembly 12 has in it a number of apertures through which this air can pass downwardly into the compartment 11. A number of these apertures are so disposed that the air, when ejecting therefrom, can cause the upper spray bar assembly to rotate in order to produce a rotary air flow which can agitate the clothes during the drying operation.
  • An air heater 49 is disposed above the spray bar 12.
  • the passage 47 may act as a condenser duct and can be supplied with cooling water if desired. The cooling fluid and condensed water will flow downwardly into the inlet 27 ofthe drain pump 26 which at this time is rotating in an operative manner. Alternatively, the moisture-laden air may be vented to the outside of the machine without continuous recirculation.
  • the drain pump 26 and the fan 45 are both operative to provide water emptying and air drying of the compartment 11.
  • the circulation pump 21 is operative in order to recycle washing or rinsing liquid through the compartment 11.
  • FIG. 2 illustrates a preferred form of an automatically operating valve which could be employed for supplying liquid to top and bottom spray bars in an alternating manner merely by switching the pump on and off.
  • This fluid distribution system is disclosed in detail in copending application U.S. Ser. No. 244,829, now abandoned.
  • outlet 33 from the valve 32 extends to an annular inlet 34 situated around fan shaft 44 upon which the lower spray bar 13 is mounted for rotation.
  • the other outlet 35 from the valve 32 communicates with a vertically extending pipe 36 extending to the upper spray bar assembly 12 in a manner to be described.
  • the form of the free wheel clutch 40 employed above the circulation pump 21 is shown in more detail in FIG. 2. It incorporates a driving part 41 carried by the upper end of the pump shaft 22 and a driven part 42 carried by the lower end of the fan and spray bar shaft 44.
  • the parts 41 and 42 are arranged to free wheel with respect to one another in one direction of rotation but to be driven one by the other in the other direction of rotation as previously described.
  • the spray bar 13 and fan 45 will be positively driven at the same time as the circulation pump 21 is running (albeit in reverse and ineffective).
  • the circulation pump 21 While in the other direction of rotation of the pump shaft 22, the circulation pump 21 is forwardly driven and operative while the fan and spray bar shaft 44 is not positively driven. Switching the circulation pump 21 on and off will alternate the flow of washing and rinsing liquid to the spray bars 12 and 13 which are rotated by water reaction through nozzles 61.
  • the spray bar 12 is integrally formed with a disc 51 provided with a pair of radial slots 52 and a number of tangentially extending air impulsion nozzles 53 disposed around the periphery of the disc.
  • the air flow is produced by rotation of the lower spray bar 13 in a positive manner by the connection provided between the pump shaft 22 and the fan shaft 44 by means of the free wheel clutch 40.
  • the configuration of the spray bar 13 can, for instance, take either of the forms shown in FIGS. 7 and 8 on the one hand, or FIG. 3 on the other hand.
  • the spray bar 13 comprises a generally longitudinal member 60 provided with spaced water outlet nozzles 61.
  • the member 60 has two air foil sections 62 which enable the spray bar to act as a fan in one direction of rotation.
  • the spray bar 13 has extending at right angles to it a pair of air foil fan blades 45 again forming a fan for circulating air in the manner previously described.
  • a duct or peripheral shroud can be provided within which the air blades can operate.
  • the clothes in the compartment 11 are washed by the self-propelled spray bars 12 and I3 supplied alternately by means of pump 21 and valve 32.
  • the same drive that is used for driving the circulation pump is arranged positively in the opposite direction of rotation to drive the lower spray bar 13 which has an integral fan formed therewith which directs air upwardly through the passageway 47 and downwardly through the slots 52 and the jet nozzles 53 in the disc 51 to cause rotation of the disc. This ensures that the air moving downwardly through the compartment 11 will traverse the whole of the compartment and agitate the clothes as it does so.
  • Temperature can be used to indicate dryness of items in a dryer and tests have indicated that this is also satisfactory where the clothes are suspended from racks and where air is directed downwardly through the clothes so that the lower parts are normally the last to dry.
  • dryness of an individual item can be indicated by placing a temperature sensor in the lowest part of such an item.
  • the cuffs or a selected garment, could be placed on or adjacent to a suitably situated fixed sensor.
  • the temperature sensor could be placed in the general path of the air in the lower part of the compartment 11 in order to sense the temperature of the air after it had passed through the clothes and before condensing and reheating, or venting.
  • a single multiple setting thermostat in this position could also sense the temperature of the wash or rinse water in the sump.
  • a free wheel clutch is arranged, in one direction of rotation,.to rotate a fan shaft 144 to which is secured a fan 145 by means of a key 144.
  • the fan 145 incorporates a hub having four radial spokes 171 connecting inner and outer sleeve portions 172 and 173 respectively. In this way a vertical passage is provided between an outlet 133 from the valve 132 and the interior of a spray bar 113 which is mounted separately from and above the fan 145.
  • the spray bar 113 has a hub 113' surrounding the upper end of the shaft 144, but when at rest having a slight clearance between the upper end of the hub 113' and a thrust washer secured to the upper end of the shaft 144. In this way the spray bar 113 is capable of slight upward movement from the position shown in FIG. 10 and such upward movement will be caused by the flow of liquid from the circulation pump 12] and valve 132. When the spray bar 113 is in its lower position of FIG. 10, however, one or more friction pads 116 are mounted on its underside and engage the upper surface of a fan guard 14.
  • a washing machine having a compartment in which supported articles are to be washed and dried by being subjected to washing and rinsing liquid distribution and drying air flow, said compartment being in communication with a circulation pumping system which recirculates liquid drained from the articles,
  • the improvement comprising a reversible motor having first and second directions of rotation, a circulation pump in said circulation pumping system, said pump being driven by said motor so as to be effective when said motor is rotated in said first direction, and ineffective when said motor is driven in said second direction, and a fan for providing air flow distribution, said fan being positively driven only when said motor is driven in said second direction.
  • said circulation pumping system includes upper and lower spray means located in the upper and lower regions respectively of said compartment.
  • an air and liquid distribution device comprising an integral spray bar and disc assembly is mounted so as to be freely rotatable, said circulation pumping system provides liquid under pressure so as to cause said spray bar and disc assembly to rotate due to liquid reaction, said air flow distribution providing air under pressure causing said spray bar and disc assembly to rotate due to air reaction, and air slots in said disc distributing the air flow when said disc is rotated by air reaction when said fan is operative.
