摘要:
A washing machine appliance is provided including a sump positioned at a bottom of a wash tub for collecting wash fluid, a drain pump assembly for selectively draining the sump, a measurement device configured for measuring movement of the wash tub, and a water level detection system comprising a pressure sensor fluidly coupled to the sump. A controller is configured to operate the drain pump assembly to drain the wash fluid, measure the movement of the wash tub using the measurement device, measure a water level within the sump using the water level detection system, and identify a fault condition in the water level detection system upon determining that the measured movement indicates that the sump is empty and the measured water level indicates that the sump is not empty.

A home appliance equipped with a drain function and a method of controlling the same are disclosed. A method of controlling a home appliance equipped with a drain apparatus includes switching ON/OFF the drain apparatus during a first time, switching on the drain apparatus during a second time after switching ON/OFF the drain apparatus, checking a variation of the water level according to a draining status, and controlling the drain apparatus based on the checked water-level variation result corresponding to the draining status.

A method of controlling a laundry treatment machine is provided. According to the method, it is possible to detect a siphon phenomenon, before performing an operation requested by a user, by performing an intermittent water supply operation and detecting a variation, if any, in the water level in a tub of a washing machine. Therefore, it is possible to prevent wash water from being discharged due to a siphon phenomenon, to prevent the waste of water, and to minimize the amount of time taken to discharge water and the amount of time taken to perform a washing operation. In addition, according to the method, it is possible to prevent the waste of a detergent by using a water supply valve for a pre-washing operation to detect a siphon phenomenon. Moreover, it is possible to prevent a water supply failure from being mistaken as a siphon phenomenon and precisely detect a siphon phenomenon by maintaining a water supply valve to be open for a predefined amount of time and then detecting a variation, if any, in the water level in a tub if the water level in a tub has been uniform or has been decreased since an intermittent water supply operation.

Provided is a self-cleaning method for a filter assembly of a washing machine, the method comprising: receiving a user operation instruction for starting a self-cleaning process; executing the self-cleaning process, so as to clean the filter assembly of the washing machine, and before the self-cleaning process is completed, only receiving user operation instructions for turning off the washing machine, pausing the self-cleaning process and unpausing the self-cleaning process, and prohibiting receipt of or ignoring the user operation instructions other than user operation instructions for turning off the washing machine, pausing the self-cleaning process and unpausing the self-cleaning process. According to the present invention, the filter assembly of the washing machine is thoroughly cleaned, prolonging the service life of the filter assembly in the washing machine and ensuring that the filter assembly always has a high filtration flux.
摘要:
A pump for pumping water from a bowl of a washing machine is provided. The pump includes a housing coupled to the bowl and a cover with an aperture. The housing and the cover define an interior in fluid communication with the bowl interior via the aperture. A filter filters water entering the interior via the aperture. The filter has a profiled wall defining a volute around the aperture, and a hood disposed above the wall. The profile of the hood perimeter substantially corresponding to the profiled wall to define a profiled space between the perimeter and the profiled wall. The profiled space allows water to enter the volute but substantially prevents elongated objects entering the volute.

An electric household appliance has a chamber that is at least partially filled with liquid during operation of the appliance. A motor drives a pump for drawing liquid from the chamber. A monitoring device detects the rotational speed and the power of the motor, compares detected values for the rotational speed and power to a predefined characteristic, and signals an exceptional state if the comparison indicates that the detected values deviate significantly from the characteristic.
