  • Patent number: 10465324
    Abstract: A washing machine appliance includes a wash tub defining a wash chamber for receipt of a load of articles for washing and a water control valve for regulating a flow of water from a water supply into the wash chamber. A controller is configured for detecting a low water level in the wash chamber, e.g., due to a low water supply pressure, by obtaining a target volume and a fill volume; obtaining an underfill limit based at least in part on the fill volume; obtaining a tub water level after attempting to fill to the target volume; obtaining a new fill level if the tub water level is less than the underfill limit; and filling the wash tub to the new fill level.

  • Publication number: 20190257018
    Abstract: A washing machine appliance includes a motor for selectively rotating a wash basket within a wash tub. A controller is configured for initiating a spin cycle by ramping up the speed of the wash basket to a target speed. The controller monitors a measured basket speed to determine whether the measured basket speed has reached a predetermined acceleration reference speed within an acceleration time limit or whether the measured basket speed has fallen below a dropout reference speed for a dropout time limit. If either condition exists, the controller adjusts the operation of the washing machine appliance, e.g., by reducing the wash basket speed to permit wash fluid entrained in the annulus to escape and reduce drag on the wash basket.

  • Publication number: 20180266036
    Abstract: A washing machine appliance includes a fluid additive detection system with a pressure sensor. A fluid conduit extends between the pressure sensor and a reservoir. An inlet of the fluid conduit is positioned adjacent a bottom wall of the reservoir, and the inlet of the fluid conduit is contiguous with an interior of the reservoir such that fluid additive within the reservoir is flowable into the fluid conduit at the inlet of the fluid conduit. A pressure measurement signal of the pressure sensor is variable as a function of a height of the fluid additive within the reservoir.

  • Publication number: 20180135229
    Abstract: A washing machine appliance has a low-flow inlet valve that is configured such that a flow of water from the low-flow inlet valve has a flow rate no greater than one gallon per minute when the low-flow inlet valve is open. A Venturi pump is connected to the low-flow inlet valve such that the flow of water from the low-flow inlet valve enters the Venturi pump at a water inlet of the Venturi pump when the low-flow inlet valve is open. The Venturi pump is operable to draw fluid from a tub through a recirculation conduit to a recirculation inlet of the Venturi pump. A nozzle is positioned and oriented for directing a flow of liquid from the Venturi pump into the tub. A related method for operating a washing machine appliance is also provided.

  • Patent number: 9863076
    Abstract: Washing machine appliance and methods for operating washing machine appliances are provided. A method includes determining a load mass in a basket of the washing machine appliance, and flowing water into a tub until a predetermined tub water indicator level is met, wherein the basket is disposed in the tub. The method further includes estimating a first volume of water in the tub after the predetermined tub water indicator level is met, and determining a load type based on the load mass and the first volume of water. The method further includes flowing water into the tub until a secondary indicator level for the determined load mass is met if the determined load type is a low pressure indicator.

  • Patent number: 9840805
    Abstract: Washing machine appliances and methods for determining load masses are provided. A method includes accelerating rotation of a basket of the washing machine appliance from a first speed to a second speed greater than the first speed and for a predetermined time measured for acceleration of the basket from the first speed; measuring, during the accelerating step, a check speed of the basket at the predetermined time; and measuring, during the accelerating step, an acceleration time for the tub to accelerate from the first speed to the second speed. The method further includes discontinuing acceleration of the basket after the second speed and the predetermined time have reached; and measuring a coast time for coasting of the basket from the check speed to the first speed. The method further includes determining a load mass in the basket based on the check speed, the acceleration time, and the coast time.

  • Patent number: 9765464
    Abstract: A method for washing articles in a wash chamber of the washing machine appliance is provided. The method includes receiving user input of a user-selected water fill amount for a wash cycle, the user-selected water fill amount being the largest water fill amount available for selection by a user. The method also includes determining a characteristic of a load of the washing machine appliance and determining that an amount of water associated with the user-selected water fill amount is inadequate for the load. In response, the method includes providing the wash chamber of the washing machine appliance with an amount of water greater than an amount associated with the user-selected water fill amount.

  • Patent number: 8931859
    Abstract: A consumer appliance has a soft open door mechanism. The mechanism may include a damping device with a first end mounted to the cabinet and a second end mounted so as to move with the door. The damping device includes a partial fill damper activatable by an opening movement of the door toward the horizontal position to provide an opposing force to slow the door motion. The damper may be configured so as to initiate the opposing force only when the door has moved at least about 45 degrees from the upright position toward the horizontal position, and/or may be configured so that the damper includes a damping coefficient of about 200 to about 240 lb*s/ft.
