Lint filter clogging detection in a dryer appliance based on airflow

A laundry appliance uses a determination of volumetric airflow rate after a steady state condition is reached to determine the accumulation of lint in filter. Based on the determination, various actions can be taken including notifying the user, shutting off the appliance, initiating an automatic cleaning sequence for one or more lint filters, and combinations thereof. One or more temperature sensors, relative humidity sensors, and weight sensors are used to provide measurements for determining the volumetric airflow rate.

The invention relates to a method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and a control device, wherein the method comprises a step for detecting when laundry is sliding and/or rolling, comprising, while rotating the drum, sampling a variable related to a torque of the motor or a rotational speed of the drum over a predetermined period of time; and determining whether the laundry is sliding and/or rolling in the drum based on the variable sampled over the period of time.

The invention further relates to a corresponding washing machine.

METHOD AND CONTROL UNIT FOR ACTIVATING DETERGENT FOR A CLEANING APPLIANCE WITH A ROTATABLE DRUM WITHOUT RIBS, AND CLEANING APPLIANCE

A detergent activation method for a cleaning appliance having a rotatable non-ribbed drum for holding the textiles) and includes a step of supplying a feed signal to a feed unit of the cleaning appliance. The feed signal causes the cleaning liquid to be fed into a suds container until a predetermined target fill level in the drum is reached. In the supplying step, a motion signal may be supplied to a drive of the cleaning appliance when the target fill level is reached, wherein the motion signal causes a rocking rhythm of the drum. The rocking rhythm defines successive rotational motions of the drum at increasing rotational speeds without a complete revolution of the drum. In the supplying step, a stop signal may be supplied to the drive when a final rotational speed of the rocking rhythm has been reached, to cause the rotational motions of the drum to stop.

Building's airflow and a clothes dryer's exhaust filtering and recycling system comprising an emergency shutdown element, condensate separation, and multiple airflow configurations within a housing
20220379254 · 2022-12-01 ·

Listed are some of this invention's unique features for producing a healthier home and a safer clothes dryer vent within the same housing system, which may be installed within a typical wall system or as a free-standing unit in a laundry room.

Included are two airflow receiving ports that accepts airflow from a clothes dryer or optionally from a house's interior rooms and two airflow exhaust ports that discharge the same airflow into an exhaust pipe to the outside or optionally into the building interior as recycled airflow.

A drainage device removes water derived from condensate which forms in the exhaust pipe and otherwise flows back into the housing.

Two (2) receiving ports and the two (2) exiting ports combine to provide four (4) combinations of airflow management.

The choice of which of the four (4) airflow ports are activated for airflow passage is subject to a selection from a control system which contains switches for the desired airflow management thru the housing.

Additionally, the control system contains monitors and sensors to indicate unsafe temperatures, air pressure changes or filter blockage within the housing.

A shutdown mechanism within the control system stops the airflow exhaust fan and stops the clothes dryer to provide an additional measure of safety.

Included in the invention is a multi-filter filtration system that includes filters that block lint particulate from a clothes dryer and block indoor pollutants comprising pre-filters, True HEPA filters, with activated carbon filters and air cleaners to meet EPA Indoor Air Quality Standards and MERV Ratings.

A multi-speed airflow exhaust fan moves airflow in thru the receiving ports, thru the multi-filters and out thru the exiting ports. Additionally, within the housing, access openings with removable windows provide internal inspections and accessibility.

In conclusion the elements of this invention combine to improve the efficiency and safety of a clothes dryer's exhaust system and improve the indoor air quality of a home or commercial building.

CLOTHES TREATING APPARATUS

The present invention relates to a clothes treating apparatus, including a communication unit to transmit or receive information related to a usage history of the clothes treating apparatus, a memory to store the information related to the usage history, an air supply device to heat air supplied into an accommodation space of the clothes treating apparatus, and a controller to extract a use time zone of the clothes treating apparatus based on the information related to the usage history, drive the air supply device in a preset pattern within the extracted use time zone, and stop an operation of the clothes treating apparatus at a time zone except for the extracted use time zone.

Intelligent network for chemical dispensing system

System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

Method for terminating remote control over washing machine

A method for terminating remote control over a washing machine wherein when shutdown control over the washing machine is triggered, the washing machine sends an instruction to terminate a channel between the washing machine and a mobile terminal connected with the washing machine, and shuts down. The shutdown control is triggered in a short-range or remote manner. By this method a termination instruction is sent before the washing machine shuts down to terminate a channel between the washing machine and the mobile terminal, it is ensured that the channel between the washing machine and a mobile terminal has already been cut off before the washing machine shuts down, such that the washing machine is no longer controlled by the mobile terminal connected with the washing machine the last time when being turned on next time, for improving security of washing machine control.
