20210302223 · 2021-09-30 ·

A washing machine appliance includes a wash tub defining a wash chamber, a wash basket rotatably mounted within the wash tub, and a motor operably coupled to the wash basket for selectively rotating the wash basket. A controller is configured for accelerating the wash basket at a predetermined acceleration rate during an acceleration period while monitoring various acceleration parameters. The controller also rotates the wash basket at a predetermined speed during a steady state period either before or after the acceleration period while measuring steady state parameters. The controller further determines a load score based at least in part on the acceleration parameters and the steady state parameters and determines a load weight based on the load score, the acceleration parameters, the steady state parameters, and a weighted transfer function.

CONTROL OF A HOUSEHOLD APPLIANCE

A method for controlling a domestic appliance includes the following steps: determining conventional operating parameters when the domestic appliance is in operation; determining a correlation of the operating parameters with respect to external information; and determining a proposal for operating the domestic appliance with the modified operating parameters if the external information deviates from a conventional value.

Phase control of DC bus in appliances

A control system of an appliance having a motor is provided. The control system includes an inverter circuit configured to provide power to the motor. The inverter circuit has a direct-current (DC) bus. The control system further includes a controller device powered by the DC bus, and a phase fired control device operatively coupled to an input of the inverter circuit. Also, the phase fired control device is configured to control a magnitude of voltage applied to the DC bus based on a phase on angle of the phase fired control device.

Method for drain standpipe height detection

A method for detecting drain standpipe height in a washing machine appliance includes activating a drain pump such that the drain pump flows wash fluid from a tub to a drain standpipe, determining a height of the drain standpipe, and adjusting operation of the washing machine appliance in response to the determined height of the drain standpipe.

20210198834 · 2021-07-01 ·

A laundry treating appliance includes a cabinet defining an interior. A rotatable treating chamber is located within the interior. A liquid recirculation system is fluidly coupled with the rotatable treating chamber. A liquid treating assembly is fluidly coupled with the liquid recirculation system. The liquid treating assembly includes a processing tank at least partially defining a liquid treating chamber configured to receive dirty wash water supplied from the liquid recirculation system for liquid treatment.

ELECTRONIC CARE AND CONTENT CLOTHING LABEL
20210182939 · 2021-06-17 ·

The system disclosed here can detect a counterfeit item by obtain an identifier (ID) of an item from the item and determining whether the ID of the item is authentic by determining whether the ID of the item is compliant with a predetermined rule, such as whether the item is included in a database of valid IDs. Upon determining that the ID of the item is compliant with the predetermined rule, the system can produce a notification that the item is authentic. Upon determining that the ID of the item is not generated by the predetermined rule, the system can produce a notification that the item is counterfeit.

APPLIANCE LIFT SYSTEM
20210262146 · 2021-08-26 · ·

A laundry appliance system includes a cabinet operable between a lowered position and a plurality of raised positions. A first lift assembly is coupled to a first side of the cabinet. A second lift assembly is coupled to a second side of the cabinet. The first and second lift assemblies operate concurrently to adjust the cabinet between the lowered position and the plurality of raised positions. A user-interface assembly is operably coupled to the cabinet. The user-interface assembly is configured to receive a user input corresponding with a selected raised position of the plurality of raised positions. A controller is configured to operate the first and second lift assemblies to the selected raised position in response to the user input.

DRAIN PUMP DRIVING APPARATUS AND LAUNDRY TREATMENT MACHINE INCLUDING THE SAME
20210156066 · 2021-05-27 ·

The present disclosure relates to a drain pump driving apparatus and a laundry treatment machine including the same. A drain pump driving apparatus according to an embodiment of the present disclosure includes a controller configured to drive a motor, during drainage, based on an output current and a direct current (DC) terminal voltage with a first power when a lift is at a first level and to drive the motor with the first power when the lift is at a second level that is greater than the first level, wherein the lift is a difference between a water level of a water introduction part through which water flows into a drain pump and a water level of a water discharge part through which the water is discharged out of the drain pump. Accordingly, water pumping can be performed smoothly even if the lift is changed during the drainage.

LAUNDRY TREATMENT MACHINE

The present disclosure relates to a laundry treatment machine. The laundry treatment machine according to an embodiment of the present disclosure includes a controller configured to increase or decrease stepwise a speed of a motor during dewatering. Accordingly, it is possible to reduce a speed ripple during dewatering.

Clothes dryer fire reduction system
11028528 · 2021-06-08 ·

A clothes dryer apparatus and system that reduces the buildup of electric charges within a dryer drum by introducing ions. The system monitors the voltage within the drum by taking measurements on voltage sensor assembly. The sensor assembly obtains a voltage when two areas of a fabric, or two separate items of the clothing, contact the sensor. If a threshold voltage is obtained, an ion generator introduces cations and anions into the drum of the dryer to neutralize the static charge of the clothing. The reduction of static electricity increases efficiency as the clothing items do not stick together which permits better heat flow and increases safety by reducing the amount of electrical charge within the drum.
