Abstract: A dishwasher, and a screen filter and a pump lower unit of the dishwasher are provided. The dishwasher includes the pump lower unit and the screen filter, a mounting protrusion and an insert hole, and a mounting knob. The screen filter is installed on the pump lower unit for removing impurities from wash liquid. The mounting protrusion and the insert hole are for aligning the screen filter with the pump lower unit. The mounting knob is for coupling a fastening member to fasten the screen filter to the pump lower unit.

Abstract: A sump assembly for preventing leakage during the flow of washing water is provided. The sump assembly includes a sump case, a fluid passage guide, a sump cover, a lower nozzle holder, and a self-cleaning filter assembly. The sump case stores washing water. The fluid passage guide is disposed on top of the sump case and includes a wash pump within for inducing a forced flow of washing water. The sump cover is mounted on top of the fluid passage guide. The lower nozzle holder firmly contacts the top of the sump cover. The self-cleaning filter assembly is disposed in a space between the sump cover and the lower nozzle holder and includes a mesh filter within for filtering foreign objects.

Abstract: There is provided a sump assembly of a dishwasher. The sump assembly includes a sump case for reserving washing water, the sump case having coupling bosses protruded upward, a sump cover seating on an upper portion of the sump case, the sump cover having a coupling boss and a coupling hole in which a coupling member is inserted, a self-cleaning filter assembly mounted on a top surface of the sump cover to filter foreign objects, the self-cleaning assembly having a coupling hole in which the coupling member is inserted, a washing pump for pumping out the washing water reserved in the sump case, a fluid passage guide for guiding flow of the washing water pumped from the washing pump, the fluid passage being mounted on a bottom of the sump cover, and a pump lower disposed between the washing pump and the fluid passage guide, the pump lower having a first coupling boss formed on a frame portion and a second coupling boss formed therein.

Abstract: There is provided a soil jam preventing structure of a dishwasher having a tub. The soil jam preventing structure includes a sump case mounted on a floor of the tub to reserve washing water and a sump cover seating on an upper portion of the sump case, the sump cover having an outer frame portion, a rib extending from the outer frame portion, and a foreign object drain groove formed by cutting away a portion of the rib.

Abstract: A heater assembly for a dryer is disclosed, which is stably assembled and reduces noise. The heat assembly for a dryer includes hot wires electrically heated, an insulator provided with a groove at the center, having lower and upper portions into which the hot wires are fixed, and a partition plate including an insertion hole into which the insulator is inserted and at least one clamp portion provided at the rim of the insertion hole and fixed into the groove.

Abstract: The present invention provides a dishwasher, by which noise and vibration of a wash motor can be lowered and by which endurance of the wash motor can be prolonged and by which an assembly of a wash motor and a sump can be simplified. The present invention includes a sump housing having a heater container containing a heater therein and at least one motor guide rib projected from a bottom of the heater container and a wash motor having a motor housing provided with a rib container containing the at least one motor guide rib therein.

Abstract: Disclosed is a dish washer including a sump for storing wash water, a supply passage having a section for dropping the wash water supplied to the sump, a flow meter for detecting a flow rate of the wash water dropped from the supply passage, a discharge pump for discharging the wash water out of the sump, and a micom for selectively operating the discharge pump according to the flow rate detected from the flow meter.

Abstract: The present invention provides a dishwasher, by which an appropriate quantity of water can be stably supplied. The present invention includes a sump storing water therein, a floater received in a chamber having a predetermined volume, the floater ascending according to a rise of a water level of the sump, a switch preventing the water from being oversupplied to the sump, a pushing member lifted by the floater to turn on the switch by pushing the switch, and an off-delay part delaying the switch to be turned off on a descent of the floater.

Abstract: A method of controlling a motor-driven washing machine and a control system that controls a motor or any other components of the washing machine are disclosed. The method includes the steps of generating an interruption command for braking a motor in motion during a wash cycle, applying a phase-reversed voltage to a voltage input terminal of the motor in motion, and electrically shorting the input terminal of the motor for a predetermined period of time if a second phase-reversed voltage generated by the motor is higher than or equal to a critical voltage level. Using such method, a motor-clutch mechanism is prevented front generating a noise and from being damaged during a wash cycle.

Abstract: A control method and system for a belt-driven clothes dryer are disclosed. The control system includes a drum containing a load of wet clothes to be dried, a heater heating air flowing into the drum, a motor coupled to the drum by a power transmission system for rotating the drum, and a power supply supplying power to the motor and the heater during a dry operation of the dryer. The control system further includes a moisture sensor outputting a sensor signal during the dry operation, or a photo coupler outputting voltage pulses when the motor is in operation during the dry operation. Then, a microprocessor included in the control system detects a breakage of the power transmission system upon analyzing the sensor signal of the moisture sensor or the voltage pulses generated by the photo coupler. If the microprocessor detects such breakage, it interrupts the dry operation of the clothes dryer.
