A washing machine drawer (50) in a washing machine (11) has a drawer body (51) with several chambers including chambers (63) for filling in detergents or additives for a washing process, sensor means (71, 76, 80) in the receptacle for analyzing water transported to the sensor means and a receptacle communication module (56) for a data connection to the outside. A control device (40) of the washing machine is communicating with the receptacle communication module (56) to receive data about analysis results from the sensors for adapting a washing process. The drawer (50) may be exchangeable to provide the washing machine with more and up to date features. The drawer (50) may also have a receptacle control (54) provided with a powerful controller to overtake some functions of the washing machine (11) besides controlling the sensor means.

An aspect of the present disclosure is to provide a washing machine that detects contamination of water due to a dye and prevents contamination of laundry due to the dye. The washing machine includes a tub; a drum configured to be rotatable inside of the tub; a detergent supplier configured to supply a detergent to the tub; a water supplier configured to supply a water to the tub; an optical sensor provided under the tub, wherein the optical sensor includes a light emitting element and a light receiving element configured to selectively receive a plurality of visible rays having different wavelengths and an infrared ray among a light emitted from the light emitting element; and a controller configured to control the water supplier to supply the detergent and the water to the tub and rotate the drum during a washing. In addition, the controller may reduce the washing time based on the sum of the received intensities of the plurality of visible rays and the received intensity of the infrared ray.

A washing machine having a reminding function for preventing clothing from fading, comprising: an outer drum for accommodating washing water; a color sensor arranged on the washing machine and detecting the color of the washing water, so that according to changes in the color of the washing water in a washing process, it is determined whether the clothing being washed is fading or not. Detection of the color of the washing water achieves the aim of determining, according to the changes in the color of the washing water, whether the clothing being washed is fading or not, thereby improving the sensitivity and accuracy of determination, and preventing a situation wherein fading clothing contaminates the washing water then causes secondary contamination of other clothing being washed.

A laundry treating appliance comprising a dispensing assembly which can identify laundry treating chemistry filled in a loading cup by way of a material sensor, and supplying said laundry treating chemistry to a proper corresponding bulk reservoir.

A laundry washing machine and method of operating same for the purpose of automatically determining a soil level of a laundry load from two turbidity readings taken before a washing cycle commences, such as during a pre-wash, filling phase. The machine is configured to detect a load size, add a first amount of water and take a first turbidity reading. A first dose of detergent is then added, a second amount of water added and the wetted load is gently tumbled/agitated before taking a second turbidity reading. A value based upon a ratio of the turbidity readings can determine the soil level of the load in order to choose a wash-related parameter, such as how much detergent to use for the subsequent complete wash cycle and/or the duration thereof.

Washing machine appliances and methods of operating the same are provided. Such methods may include, and/or appliances may be configured for, receiving a command to commence an operating cycle of the washing machine appliance and filling the wash tub with wash liquid from a fluid circulation system configured for providing fluid to the wash tub via an inlet of the fluid circulation system in response to the command. Methods may further include and/or appliances may be configured for, obtaining one or more images of the inlet of the fluid circulation system during the fill step using a camera mounted within the cabinet. The camera is positioned and oriented with the inlet within a field of vision of the camera. Based on the one or more images, a determination is made whether a water pressure provided to the fluid circulation system is above a predetermined minimum water pressure.

A washing machine for washing laundry may include a drum type washing machine having a tub, a drum, a water pressure and/or level sensor, an air flow path, a bubble detecting sensor, and a controller. The bubble detecting sensor may be along the air flow path of the tub in order to detect whether bubbles, suds or foam are generated within the tub and/or whether the bubbles, suds or foam exceed an acceptable amount. When the bubbles within the tub are detected and/or exceed the acceptable amount, the washing machine (e.g., the controller) may perform a preset or predetermined bubble removing course or procedure to remove or reduce the bubbles.
