摘要： The present disclosure relates to a laundry treatment machine. A drain laundry treatment machine according to an embodiment of the present disclosure: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a drain motor; an output current detector to detect an output current flowing in the drain motor; and a controller to control the drain motor to rotate at a speed lower than a first speed when the output current flowing in the drain motor decreases in a state where a speed of the drain motor is the first speed. Accordingly, it is possible to reduce a pressure in a vortex chamber of the drain pump during dewatering.

摘要： A laundry washing machine and method utilize a fluid property sensor to sense a fluid property of a fluid during a wash cycle to sense the level of detergent remaining in a load and control a rinse operation performed thereafter based upon the sensed fluid property. In some instances, the fluid property may be sensed while the load is being spun at a rate sufficient to cause fluid to be released from the load such that the sensed fluid property is based at least in part on fluid that was previously absorbed into the load. In addition, in some instances, the fluid property may be sensed during a spin phase of a wash cycle to selectively cause a wash cycle to selectively revert to an additional rinse phase when required, or otherwise proceed directly to the remainder of the spin phase to complete the wash cycle.

摘要： An apparatus, which is a drive apparatus, includes: a drive unit; a controller that obtains an application including a plurality of blocks, and executes the application to control the drive unit in accordance with the plurality of blocks; a first sensor; and a second sensor. Each of the plurality of blocks includes an end condition. When, during execution of a first block, the first driving state detected by the first sensor meets the end condition of the first block and the second driving state detected by the second sensor meets a block insertion condition, the controller: inserts a new block before a second block contiguous to the first block; and controls the drive unit in accordance with the new block and the second block.

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 and a laundry treatment machine including the same include: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and to output the converted AC voltage to a drain motor; and a controller to control the motor to, when a drain channel in a drain pump is clogged, be temporarily stopped in a period during which a speed of the motor increases and then to repeatedly rotate and stop in a first direction the same as a start-up direction, and to repeatedly rotate and stop in a second direction opposite to the first direction when the drain channel is clogged even after the motor repeatedly rotates and stops in the first direction. Accordingly, when impurities are introduced into the drain pump, the impurities can be removed in a simple manner.
