Abstract: A foam sensor of a drum washing machine is constructed such that a pair of temperature electrode terminals and a foam electrode terminal are supplied with electricity by a single connector, and thus is able to sense an electrical connection by a signal change of the temperature electrode terminals, in a case where electrical connection of the foam electrode terminal is cut off, thereby preventing a false sensing of foam generation caused by electrical short-circuiting of the foam electrode terminal. Furthermore, the foam electrode terminal is provided integral with the connector, and the temperature sensor portion has a thermistor for sensing a temperature of washing water and temperature electrode terminals inserted into the connector, the thermistor and the temperature electrode terminals being connected by a cord, which makes installation easier.

Abstract: There is provided a washing machine combined with a dryer. In the washing machine, a tub is provided, a lint collector is connected to the tub to collect lint, an air-vent pipe is connected to the lint collector, a dryer duct is connected to the tub and it is provided with a blower fan therein, and a water drain line is provided to discharge water from the tub to an outside of the washing machine.

Abstract: There is provided a washing machine combined with a dryer. In the washing machine, a cabinet is provided, a tub is installed in the cabinet, an air-vent hose is installed to an outer surface of the tub, a lint filter assembly has one end connected to the air-vent hose to remove lint from air discharged from the tub, and an air-vent duct is connected to the other end of the lint filter assembly.

Abstract: A washing machine combined with a dryer is provided. In the washing machine combined with a dryer, a tub is provided, a dryer duct is installed outside of the tub to introduce a surrounding air into the tub, a heater is installed in the dryer duct to apply heat to the surrounding air, a temperature sensor is installed in the dryer duct to measure temperature inside the tub or temperature inside the dryer duct, and a dryer fan is installed in the dryer duct to draw in the surrounding air.

Abstract: A washing machine is provided. The washing machine includes a driver, an electrode sensor, and a controller. The driver operates each part of the washing machine. The electrode sensor detects bubble generation using a voltage change between the electrodes when the bubbles contact the electrodes during the washing cycle. The controller controls the driver using a bubble detection signal from the electrode sensor to allow a bubble-removal cycle to be performed. Therefore, when the bubbles are excessively generated during the operation of the washing machine, the bubble generation can be swiftly detected and the relevant operation is performed thereto.

Abstract: A washing machine combined with a dryer is provided. In the washing machine combined with the dryer, a tub is provided, a dryer duct is installed outside of the tub, a dryer fan is installed in the dryer duct to draw in a surrounding air, a heater is installed in the dryer duct to apply heat to the drawn-in air, and a screening unit is installed in the dryer duct to selectively block the flow of the air, wherein the dryer duct includes an air inlet to introduce the surrounding air, an air outlet connected to the tub to allow the introduced air to flow into the tub, and an air passage formed between the air inlet and the air outlet to pass the introduced air therethrough.
