A control method of a washing machine includes performing a first drum operation of supplying water by a first set amount together with a detergent into the tub and rotating the drum at a first drum rotation speed, while water is supplied performing a pump speed-change operation of accelerating the pump from a first pump rotation speed to a second pump rotation speed and then decelerating to the first pump rotation speed at least once during the first drum operation and performing a second drum operation of operating a heater to heat the water in the tub in a state in which the first set amount of water is supplied into the tub, rotating the drum at a second drum rotation speed during the operation of the heater, and performing a pump constant-speed operation of operating the pump at a third pump rotation speed during the second drum operation.

An apparatus includes at least one of an actuator or a heater, and a controller that controls the at least one of the actuator or the heater. The controller: obtains an application defined by a plurality of blocks that drive the at least one of the actuator or the heater, each of the plurality of blocks including a parameter for driving the at least one of the actuator or the heater; consults a first rule that defines a first parameter range within which the at least one of the actuator or the heater is not permitted to be driven, and modifies the application by changing at least one block included in the plurality of blocks, the at least one block including a parameter included in the first parameter range; and drives the at least one of the actuator or the heater based on the modified application.

A cleaning appliance and method for operating a cleaning appliance with a rotatable, non-ribbed drum for the pre-treatment and main treatment of textiles. The method comprises a step of supplying a feed signal for feeding a cleaning liquid into a suds container until a predetermined initial fill level is reached. A saturation action causes the textiles to be pre-treated to be saturated with the cleaning liquid. The method includes reading in a fill level signal that represents a fill level of the cleaning liquid, and supplying a further feed signal for feeding the cleaning liquid into the suds container until a target fill level is reached. A motion signal causes a rocking rhythm of the drum for pre-treating the textiles to be pre-treated. After the pre-treatment, an unlocking of a drum door takes place in order to allow additional textiles to be added for a main treatment of the textiles.

The invention relates to a portable device (1100) comprising a bottom surface (BS) intended to be in contact with a textile (TXT). The portable device comprises an image sensor (5) for taking an image of a textile, and an illumination system (6) for illuminating a portion of the textile when said image is being taken. The portable device also comprises a control unit (8a) for executing an algorithm stored in the portable device, using the taken image as an input of said algorithm, to obtain a classification of the textile. The image sensor and the control unit are integrated within the portable device. The image sensor has an active surface sensitive to light, which is oriented compared to said bottom surface (BS), with an absolute value of the orientation angle being in the range 15-70 degrees; and/or the illumination system (6) has a light source oriented compared to the said bottom surface (BS), with an absolute value of the orientation angle being in the range 15-70 degrees.

A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A camera assembly is used to monitor articles for washing within the wash basket. Specifically, a controller of the washing machine appliance uses the camera assembly to obtain a reference image and one or more test images, which utilize image recognition to assess turn-over of the articles for washing during a given wash cycle. When turn-over performance is inadequate, a controller may adjust one or more operating parameters of the wash cycle to improve performance. Turn-over performance of the wash cycle is determined to be adequate once the image recognition process fails to find adequate correlation between the reference image and the test image a predetermined number of times.

A control method of a double-drum washing machine, having a first washing drum and a second washing drum. Whether the heating time required by the first drum is overlong is judged before the first drum performs heating. If yes, the second drum executes the heating, or dewatering, or drying processes. If not, the following steps are performed: judging whether the second drum performs heating; if yes, judging whether the remaining heating time of the second washing drum is greater than T.sub.0; if the judgment result is yes, executing the alternate heating program that the first drum and the second washing drum perform heating alternately, and if the judgment result is no, executing the ordered heating program that the second drum performs heating firstly, and then the first drum performs heating, wherein T.sub.0 is a time value for judging whether the heating of the second drum is about to finish or not.

In a control method of a washing machine, a washing operation is performed through a heating washing process for a first set time and is performed through a non-heating washing process for a residual time, and, if the heating washing process is started, the rotation of a driving motor is weakly controlled until a washing water temperature reaches a primary target temperature, and is strongly controlled until the washing water temperature reaches a secondary target temperature after the washing water temperature reaches the primary target temperature, so that the washing water temperature is relatively gradually increased.

The subject disclosure relates to a clothing washing system, an apparatus for generating nano microbubble ionic water, and a method of washing clothes. The clothing washing system includes an adjustment unit, an electrolysis unit, a first fluid circulation unit, a nano microbubble generation unit, a second fluid circulation unit, and a cleaning unit. The electrolysis unit is in fluid communication with the adjustment unit. The first fluid circulation unit is connected to the adjustment unit and the electrolysis unit. The nano microbubble generation unit is in fluid communication with the adjustment unit. The second fluid circulation unit is connected to the adjustment unit and the nano microbubble generation unit. The cleaning unit is in fluid communication with the adjustment unit.

A method of laundering fabric including: (a) calculating a final amount of water to be added to a final wash bath; (b) calculating the amount of energy needed to heat this final amount of water to a desired final temperature; (c) contacting an amount of water that is less than the final amount water with fabric to form an intermediate wash bath, wherein a detergent composition is contacted to the fabric during the formation of the intermediate wash bath, or prior to the formation of the intermediate wash bath; (d) heating the water that contacts the fabric during (c) with the energy calculated in (b) such that the intermediate wash bath has a temperature above the desired final temperature; (e) washing the fabric in the intermediate wash bath for at least 3 minutes; (f) contacting the remaining amount of water to the intermediate wash bath to form the final wash bath having the desired final temperature; (g) washing the fabric in the final wash bath for at least 5 minutes; and (h) rinsing the fabric.

A washing machine that performs a washing course by heating wash water and a control method thereof are provided. The method includes supplying wash water up to a wash water level for generation of steam such that a portion of laundry received in an inner tub is saturated by the wash water. The wash water level may be above a bottom surface of the inner tub and below a wash water level for main washing. The method then includes heating the wash water to a first set temperature and driving a washing heater to generate steam from the wash water, and supplying the generated steam to the inner tub, and then supplying the wash water up to the wash water level for main washing, and driving the washing heater again to heat the wash water to a second set temperature, the second set temperature being lower than the first set temperature.
