摘要:
A washing machine and control methods thereof to enhance washing quality, even when using eco-friendly natural soap-based detergent. Controlling a rinse water temperature based on a wash water temperature to reduce a temperature difference therebetween prevents gelation caused by natural soap-based detergent and maximizes washing quality when using this type of detergent.

A water level sensing apparatus which more precisely senses a level of supplied water, a water supply hose and a washing machine having the same is provided. The water level sensing apparatus includes a main body provided with an inner wall and an outer wall and filled with water supplied to the inside of the inner wall, a plurality of electrodes inserted between the inner wall and the outer wall to be opposite to each other, and a micro-computer to judge a water level in the main body through variation of a capacitance value of the plurality of electrodes. Therethrough, the water level sensing apparatus more directly measures a water level, as compared to the conventional water level sensing apparatus, thus improving precision in water level measurement. Thereby, the water level sensing apparatus prevents unnecessary water supply and reduces energy consumption.

Disclosed herein are a dryer and a drying method of the same. The dryer includes a condensing unit to change water vapor evaporated from a drying object into condensate water by cooling, a condensate water storage container in which the condensate water is stored, a water level sensing device to detect a level of the stored condensate water, and a microcomputer to calculate a change rate of condensation or of the condensate water level based on the detected water level and to determine a value of dryness of the drying object. The dryer effectively performs a drying operation based on the accurately detected value of dryness of the drying object.

A control method of a washing machine is capable of safely achieving a tub washing operation control with low power consumption. At the time of performing tub washing, water of which the amount is decided depending on a volume inside a drum and a volume inside a water tub is supplied to the water tub, and the rotation speed of the drum is controlled to be inversely proportional to the volume of the supplied water, thereby efficiently controlling a tub washing operation with low power consumption. Also, the rotation state of the drum is controlled, at the time of performing the tub washing, to maintain the temperature of a motor or a printed circuit board (PCB) to be a predetermined level or less, thereby safely controlling a tub washing operation with low power consumption. In addition, it is determined whether the revolutions per minute (RPM) of the drum rotating at the tub washing operation belong to a resonance band, and the RPM are controlled such that the RPM deviate from the resonance band, thereby achieving a tub washing operation procedure with small noise and vibration.

Disclosed is a direct-coupled washing machine and a control method thereof. The direct-coupled washing machine connects the rotation shaft of a switched reluctance washing motor to the rotation shafts of both a pulsator and a dehydration water tub. The direct-coupled washing machine has a pulsator which is mounted in the dehydration water tub which forwardly or reversely rotates in a washing procedure to thereby agitate the laundry. The washing machine includes: a washing motor which has a copper-core rotation shaft connected with the dehydration water tub and the pulsator, and generates rotational force; a reduction portion which reduces the speed of the rotational force generated by the washing motor by using a constant ratio; and a connection switching portion which is connected to the rotation shaft of the pulsator in a washing procedure by connecting the reduction portion to the rotation shaft of the washing motor, and is directly connected to the rotation shaft of the dehydration water tub in a dehydration step by not connecting the rotation shaft of the washing motor to the reduction portion.
