摘要： 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.

摘要： A capacitive proximity control device (28) for a domestic washing machine (10) or other domestic electrical appliance is proposed. In some embodiments, the proximity control device comprises two planar sensor electrodes (34, 36) arranged on a door (20) of the washing machine at a spatial distance from one another. An electronic assembly is connected to the two sensor electrodes, which electronic assembly is adapted to generate, in association with each of the two sensor electrodes, an electrical sensor signal which is representative of a change in a capacitance associated with the sensor electrode in question. By mutual correlation of the two sensor signals, the electronic assembly is able to determine a proximity operation of the control device. A shielding electrode can be arranged in the spatial region between the two sensor electrodes.

摘要： A washing machine appliance includes a cabinet with a basket rotatably mounted within the cabinet and a motor configured to rotate the basket. The washing machine appliance also includes a controller in operative communication with the motor to regulate a speed of the motor. The controller may be configured for, and methods of operating the washing machine appliance may include, activating the motor to rotate the basket at a rotational speed within a predetermined speed range and measuring the rotational speed of the basket with the controller. The controller may also be configured for, and the method may also include, monitoring an ambient temperature inside the cabinet of the washing machine appliance and applying an offset to the measured rotational speed when the monitored ambient temperature exceeds a threshold.

摘要： A water ozonation system (18) that receives source water (16) from a water source (14) and converts it to ozonated water (20) for use in a washing machine (12) includes a system body (30), an ozone generator (38), a sensor assembly (21), and a controller (46). The system body (30) receives the source water (16) from the water source (14). The ozone generator (38) is configured to generate ozone. The ozone generator (38) is coupled the system body (30). The sensor assembly (21) is also coupled to the system body (30). The sensor assembly (21) is configured to sense at least one ambient environmental condition and generate at least one electronic data signal based on the sensed at least one ambient environmental condition. The controller (46) receives the at least one electronic data signal from the sensor assembly (21) and regulates a level of ozone that is generated by the ozone generator (38) based at least in part on the at least one electronic data signal.
