Definitions

  • Laundry treating appliances such as a washing machine, may have a rotatable drum in which laundry may be placed for treatment.
  • the rotatable drum defining a treating chamber, resides within a liquid holding tub, which may be mounted by a suspension system to a cabinet.
  • the tub and drum including any contents, form a suspended mass subject to the damping forces of the suspension.
  • the rotating drum may be in the imbalance condition, which may lead to movement of the suspended mass, especially at higher rotational speeds and/or at rotational speeds corresponding to known dynamic modes of the appliance, such as pendulum mode, where the suspended mass tends to swing back and forth like a pendulum, which may cause the appliance to rock, and a vertically rocking/bouncing mode, where the appliance essentially jumps up and down.
  • known dynamic modes of the appliance such as pendulum mode, where the suspended mass tends to swing back and forth like a pendulum, which may cause the appliance to rock, and a vertically rocking/bouncing mode, where the appliance essentially jumps up and down.
  • the rocking and jumping modes typically make undesirable noise and are not desired by the consumer.
  • US 5042276 relates to a laundry treating appliance and method for forming a liquid inertial mass in the tub by providing a predetermined amount of liquid to the tub, and executing an extraction phase by accelerating the rotational speed of the drum toward an extraction speed while the liquid inertial mass is in the tub during the extraction phase.
  • Such solution allows reducing the whirling of the drum related to first order vibration, but it does reduce the whirling related to a second order vibration encountered at higher spinning speeds.

  • the liquid may include one of wash liquid and rinse liquid.
  • the wash liquid may have at least one of water and a wash aid.
  • the rinse liquid may have at least one of water and a wash aid.
  • the clothes mover may typically be moved in a reciprocating rotational movement.
  • the drum rotates about a vertical axis generally perpendicular to a surface that supports the washing machine.
  • the rotational axis need not be vertical.
  • the drum may rotate about an axis inclined relative to the vertical axis.
  • the "horizontal axis" washing machine refers to a washing machine having a rotatable drum, perforate or imperforate, that holds fabric items and washes the fabric items by the fabric items rubbing against one another as the drum rotates.
  • the drum rotates about a horizontal axis generally parallel to a surface that supports the washing machine.
  • the rotational axis need not be horizontal.
  • the drum may rotate about an axis inclined relative to the horizontal axis.
  • horizontal axis washing machines the clothes are lifted by the rotating drum and then fall in response to gravity to form a tumbling action.
  • Mechanical energy is imparted to the clothes by the tumbling action formed by the repeated lifting and dropping of the clothes.
  • Vertical axis and horizontal axis machines are best differentiated by the manner in which they impart mechanical energy to the fabric articles.
  • the illustrated exemplary washing machine of FIG. 1 is a vertical axis washing machine.
  • the laundry treating appliance 10 may include a housing 14, which may be a cabinet or a chassis and/or a frame to which decorative panels may or may not be mounted.

  • a clothes mover 38 may be located in the drum 30 to impart mechanical agitation to a load of laundry placed in the drum 30.
  • the drum 30 and the clothes mover 38 may be driven by an electrical motor 40 operably coupled with the drum 30 and clothes mover 38.
  • a clutch assembly 41 may be provided to selectively operably couple the motor 40 with either the drum 30 and/or the clothes mover 38.
  • the clothes mover 38 may be oscillated or rotated about its axis of rotation during a cycle of operation in order to produce high water turbulence effective to wash the load contained within the treating chamber 32.
  • the motor 40 may rotate the drum 30 at various speeds in either rotational direction about an axis of rotation.

  • liquid supply system may differ from the configuration shown, such as by inclusion of other valves, conduits, wash aid dispensers, heaters, sensors such as a liquid level sensor, a weight sensor, a motor torque sensor, a temperature sensor, a transducer such as potentiometer, and the like, to control the flow of treating liquid through the laundry treating appliance 10 and for the introduction of more than one type of detergent/wash aid.
  • sensors such as a liquid level sensor, a weight sensor, a motor torque sensor, a temperature sensor, a transducer such as potentiometer, and the like, to control the flow of treating liquid through the laundry treating appliance 10 and for the introduction of more than one type of detergent/wash aid.
  • a liquid recirculation system may be provided for recirculating liquid from the tub 34 into the treating chamber 32. More specifically, a sump 60 may be located in the bottom of the tub 34 and the liquid recirculation system may be configured to recirculate treating liquid from the sump 60 onto the top of a laundry load located in the treating chamber 32.
  • a liquid remover in the form of a pump 62 may be housed below the tub 34 and may have an inlet fluidly coupled with the sump 60 and an outlet configured to fluidly couple to either or both a household drain 64 or a recirculation conduit 66. In this configuration, the pump 62 may be used to drain or recirculate wash water in the sump 60. As illustrated, the recirculation conduit 66 may be fluidly coupled with the treating chamber 32 such that it supplies liquid into the open top of the drum 30.
  • the liquid recirculation system may include other types of recirculation systems.
  • the laundry treating appliance 10 may further include a controller 70 coupled with various working components of the laundry treating appliance 10 to control the operation of the working components.
  • the controller 70 may be provided with a memory 72 and a central processing unit (CPU) 74.
  • the memory 72 may be used for storing the control software that may be executed by the CPU 74 in completing a cycle of operation using the laundry treating appliance 10 and any additional software.
  • the memory 72 may also be used to store information, such as a database or table, and to store data received from the one or more components of the laundry treating appliance 10 that may be communicably coupled with the controller 70.

  • the laundry treating appliance 10 may perform one or more manual or automatic treating cycles or cycle of operation.
  • a common cycle of operation includes a wash phase, a rinse phase, and a spin extraction phase.
  • Other phases for cycles of operation include, but are not limited to, intermediate extraction phases, such as between the wash and rinse phases, and a pre-wash phase preceding the wash phase, and some cycles of operation include only a selected one or more of these exemplary phases.
  • the drum 30, tub 34, clothes mover 38, motor 40 and any liquid or laundry in the treating chamber 32 and tub 34 may be thought of as a mass that is suspended from the housing 14 by the suspension system 35, which is illustrated by the struts 36.
  • the suspension system 35 will have various dynamic modes that may change depending on the rotational speed of the drum, especially when laundry resides within the treating chamber 32, and more especially when the laundry is non-uniformly distributed relative to the rotational axis and forms an imbalance.
  • the drum may rotate in accordance with a cycle of operation.
  • the laundry imbalance during the rotation of the drum 30 may induce the drum 30 to deviate off an anticipated rotational orbit and move the drum 30 in a side-to-side direction, which may be referred to as the pendulum mode because the suspended mass is essentially swinging back and forth on the struts 34 within the housing 14.
  • Such back and forth swinging may result in laundry treating appliance 10 "waking" on the floor on which the laundry treating appliance is located and/or the drum 30 may collide with the surrounding tub 34 and/or housing 14 to generate uncomfortable noise or even incur physical damage such as wear to the tub 34 and/or cabinet dents.
  • the rotational speed of the drum 30 at which the pendulum mode is present is typically a function of the structure of the specific machine.
  • the pendulum mode occurs between 50-90 rpm as the drum 30 transitions to speeds where the laundry tends to "satellize” with the drum 30. That is, the centrifugal force applied to the laundry is sufficient for the laundry to "stick” to the drum 30 and not move.
  • the pendulum mode tends to correspond to the first natural frequency of the suspended mass.
  • a vertical travel mode is another dynamic mode that occurs when the suspended mass starts reciprocating up and down, which in severe cases may cause part of the suspended mass to contact the cabinet, causing related movement laundry treating appliance 10.
  • the rotational speed of the drum 30 at which the vertical travel mode occurs is also machine-dependent.
  • the vertical travel mode occurs around 170-240 rpm.
  • the vertical travel mode tends to correspond to the second natural frequency of the suspended mass.
  • the user generally may need to stop the operation of the laundry treating appliance 10 to redistribute the laundry in the drum 30 followed by re-starting the operation, which may take an extended washing cycle time and results in a customer unsatisfaction.
  • the user may relieve a portion of the laundry of the laundry treating appliance 10 to treat the portion of the laundry next time.
  • the invention addresses the problems associated with these different dynamic modes by creating a liquid inertial mass in the tub 34 during the pendulum mode and removing the liquid inertial mass, if present, prior to the vertical travel mode.
  • the liquid inertial mass tends to retard the movement of the tub during the pendulum mode, but may exacerbate the vertical travel mode.
  • FIG. 3 schematically illustrates the presence of the liquid inertial mass 63 within the tub 34.
  • the liquid inertial mass 63 may be used any time during the cycle of operation where the drum 30 is to be rotated, especially at low speed ranges, for example, less than 200 rpm. It is generally understood that some exemplary phases such as the pre-wash phase, the wash phase and the rinse phase may be followed by an extraction phase during which the liquid is drained from the laundry or the tub 34.
  • the extraction phase may be generally conducted by centrifugally rotating the drum 30 about a rotational axis to a predetermined spin speed for a predetermined time period such that practically all of the liquid may be removed out of the tub 34 according to a cycle of operation.
  • the liquid inertial mass 63 is particularly useful during an extraction phase, especially where low drum rotational speeds are maintained.
  • the formation of the liquid inertial mass 63 may be done in any suitable manner. Liquid can be supplied directly to the tub 34 whenever it is desired to form the liquid inertial mass 63. In order to conserve liquid consumption, the liquid inertial mass 63 may be formed from liquid already present in the tub 34. Advantageously, most extraction phases occur after liquid is already provided in the tub 34 for the corresponding cycle of operation. Therefore, the liquid already present in the tub 34 may be used to form the liquid inertial mass 63. If the liquid present is insufficient to form the desired liquid inertial mass 63, then more liquid is added to the already present liquid. If too much liquid is present for the liquid inertial mass 63, then some of the present liquid is removed from the tub 34 until the desired amount of liquid remains for the liquid inertial mass 63.
  • the pump 62 may deactivate, and the inlet and outlet of the pump 62 may be configured to be closed to maintain the LIM.
  • the extraction phase may begin by increasing the rotational spin speed of the drum 30 up to an intermediate spin speed, for example 30 rpm, for a dwell for a predetermined time period, followed by increasing up to a threshold spin speed, for example 100-125 rpm, for another dwell for a predetermined time period.
  • an intermediate spin speed for example 30 rpm
  • a threshold spin speed for example 100-125 rpm
  • the spin speed and/or dwell time for the intermediate spin step and the threshold spin step may vary, depending on the configuration of the laundry treating appliance 10.
  • the rotational speed of the drum 30 passes through the speed range where the suspended mass is subject to the pendulum mode.
  • the liquid inertial mass 63 in the form of the residual liquid in the tub 34 tends to retard the movement of the suspended mass as it passes through the pendulum mode because of the increased inertial of the suspended mass.
  • Another benefit of the liquid inertial mass 63, unlike solid material, is that the liquid inertial mass 63 may not immediately respond to an applied force. Instead, the liquid inertial mass 63 may lag behind to compensate for the tub/drum movements that may be observed in the tub 34 that does not hold any residual liquid during spinning. As a result, for the same degree of imbalance, suspended mass will have less movement during the pendulum mode.
  • the drum 30 is normally accelerated to an extraction speed, which is often greater than 500 rpm, and necessarily passes through the vertical travel mode.
  • an extraction speed which is often greater than 500 rpm, and necessarily passes through the vertical travel mode.
  • the liquid inertial mass 63 is removed from the tub 34, such as by activating the pump 62 to drain the liquid inertial mass 63 from the tub 34.
  • the drum 30 may then be accelerated through the speed range where the vertical travel mode is encountered. It is contemplated that the liquid inertial mass 63 will be drained during the dwell at 100-125 rpm so that the presence of the liquid inertial mass 63 does not interfere with imbalance detection.
  • the LIM may be satisfied by removing a certain amount of liquid that is initially supplied to the tub 34
  • the LIM may be satisfied by adding liquid 63 to the tub 34 from outside the tub 34.
  • the laundry may be sometimes treated in a recirculating wash phase, where the liquid is recirculated from the sump 60 through the recirculation circuit 66 to provide the liquid on top of the laundry, and generally less amount of liquid may be consumed than other wash phase such as a tumble wash phase where generally more liquid is required for treating laundry.
  • the amount of liquid consumed for the recirculating wash phase may be less than the amount of liquid that is required to form the liquid inertial mass 63, and some amount of liquid may need to be added to the tub 34 from outside the tub 34 to compensate for the difference and to form the liquid inertial mass 63 to reduce drum excursions during spin.
  • the amount of liquid required for the liquid inertial mass 63 may be determined by the geometrical and functional constraints of the laundry treating appliance 10 which is in use for the laundry treatment, and may be different from one appliance to another.
  • the LIM may be determined to be below a level where an overflow out of the tub 34 does not occur during a cycle of operation.
  • the LIM may be determined to be below a level below where rotating of the drum 30 will not generate sufficient suds that a suds lock may occur.
  • the LIM may be determined to be below a level where a water ring may be generated between the drum 30 and tub 34 during an extraction phase.
  • the invention described here may not be limited to the wash phase in a cycle of operation.
  • the invention may be used in conjunction with any phase such as pre-wash phase, wash phase, rinse phase, or other cycles of operations including one or more of these exemplary phases, which may followed by an extraction phase.
  • the invention described herein uses liquid inertial mass to compensate for any nonuniformity of the laundry distributed received in the drum of the laundry treating appliance, and minimizes the excursions of the drum and cabinet hits during a cycle of operation. As a result, the drum excursions and side-to-side walk of the laundry treating appliance can be prevented. The collision between the drum and the tub or housing can be also prevented; therefore, the noise generation can be also minimized. It is also noted that the invention may use liquid that is already being used in a cycle of operation for the treatment of the laundry, which incurs no additional cost.
