A laundry washing machine and method utilize weight, fluid level and fluid property sensors to dynamically select a load type, control a wash cycle and control an amount of detergent dispensed during a wash cycle.

A washing machine and a control method therefor are disclosed. The washing machine comprises: a sensor for emitting white light, which includes infrared (IR) light, at washing water and receiving, from the white light emitted at the washing water, visible light of a specific wavelength and infrared light of a specific wavelength, which are reflected by the washing water or penetrate the washing water; and a processor for determining turbidity and the color of the washing water on the basis of the intensity and patterns of the visible light and the infrared light of the specific wavelengths, which are received from the sensor, and controlling an operation of the washing machine on the basis of the turbidity and the color of the washing water.

Systems, apparatuses and methods for controlling the various phases and in particular in a wash cycle of a wash machine are provided. In particular, the present application relates to controlling the water levels and detergent composition concentrations in order to reduce the amount of water and composition required to provide improved soil removal. The systems, apparatuses and methods provided allow for the use of less water and lower quantities of more concentrated detergent compositions which are customized to the types of soil to be removed.

A method of controlling a laundry treatment apparatus includes: determining whether bubbles have been generated in a tub of the laundry treatment apparatus in a state in which a second washing apparatus of the laundry treatment apparatus is operated based on a sequence of operations; and based on a determination that bubbles have been generated, reducing bubbles by (i) adding at least one first operation to the sequence of operations or (ii) replacing at least one second operation of the sequence of operations.

A laundry washing machine and method automate the selection of one or more parameters of a wash cycle of a laundry washing machine based in part on a color detection sensor disposed proximate an opening of the wash tub and configured to capture color composition data of one or more items added to the wash tub and a weight sensor operatively coupled to the wash tub, where the weight sensor is configured to detect the addition of an item among the one or more items to the wash tub and initiate capturing of the color composition data, and a controller is configured to configure one or more parameters for a wash cycle based upon the captured color composition data.

Disclosed herein is a washing machine including a door including an external cover and an internal glass to open and close a laundry entrance, at least one image sensor disposed to face the internal glass to acquire image data, a detergent bubble recognizer configured to recognize detergent bubble from the image data through a machine learning based image recognition model, and a controller configured to perform control to perform an additional rinsing cycle based on a result of recognition.

A method of controlling a washing machine includes the steps of: (a) processing the laundry by using the water supplied together with detergent; (b) draining the water used in the step (a), rotating the inner tub at a high speed, and operating the pump to drain the water discharged from the laundry; (c) rotating the inner tub at a first speed and supplying the water into the inner tub via the dispenser; (d) stopping the supply of water through the dispenser, rotating the inner tub at a second speed, and supplying the water into the inner tub through the spray nozzle; (e) stopping the supply of water through the spray nozzle and alternately rotating the pulsator at a third speed in both directions; (f) stopping rotation of the pulsator, rotating the inner tub at the second speed for a preset time, and supplying the water into the inner tub through the spray nozzle; (g) decelerating the inner tub from the second speed to a fourth speed, and operating the pump while the inner tub rotates at the fourth speed to drain the outer tub; and (h) accelerating and rotating the inner tub from the fourth speed to dewater the laundry.
