Abstract
A drum washing machine including a water tub, a rotary tub rotatably provided in the water tub, a detergent feed pipe having a first end connected to the water tub and a second end disposed at an inlet of the rotary tub, and a detergent feed unit to feed a detergent contained in the water tub into the rotary tub through the detergent feed pipe, wherein the detergent feed unit dissolves the detergent before feeding the detergent into the rotary tub in response to the detergent being a powdered detergent.
Claims15
A drum washing machine, comprising:
- a key input unit receiving an input from a user;
- a water tub;
- a rotary tub rotatably provided in the water tub;
- a detergent feed pipe having a first end connected to the water tub and a second end disposed at an inlet of the rotary tub;
- a control unit determining whether a detergent used is a powdered detergent or a liquid detergent based on the input from the user;
- and
- a detergent feed unit to feed the detergent contained in the water tub into the rotary tub through the detergent feed pipe, the control unit controlling the detergent feed unit to dissolve the detergent before feeding the detergent into the rotary tub in response to a determination from the control unit that the detergent is a powdered detergent;
- wherein the detergent feed unit comprises a control unit to drive a pump provided at the detergent feed pipe to sufficiently dissolve the powdered detergent and then feed the dissolved powdered detergent into the rotary tub.
A drum washing machine, comprising:
- an key input unit receiving an input from a user;
- a water tub;
- a rotary tub provided in the water tub;
- a control unit determining whether a detergent used is a powdered detergent or a liquid detergent based on the input received through the key input unit;
- and
- a detergent feed unit to feed the detergent contained in the water tub into the rotary tub, the control unit causing the detergent feed unit to drive a pump provided at the detergent feed pipe to sufficiently dissolve the detergent before feeding the detergent into the rotary tub in response to a determination from the control unit that the detergent is a powdered detergent.
A drum washing machine, comprising:
- a key input unit receiving an input from a user;
- a water tub;
- a rotary tub;
- a spraying unit;
- and
- a control unit determining, based on the input received through the key input unit, whether the detergent is powdered or liquid, causing a pump to sufficiently dissolve a detergent contained in the water tub in response to the determination by the control unit, and then causing the spraying unit to spray the dissolved detergent into the rotary tub by the spraying unit to soak a center of a laundry load.
A drum washing machine, comprising:
- a key input unit receiving an input from a user;
- a water tub;
- a rotary tub provided in the water tub;
- and
- a detergent feed unit;
- a control unit making a determination based on the input received from the key input unit as to whether a detergent is a first type of detergent or a second type of detergent and selectively causing the first type of detergent to be dissolved in the detergent feed unit before being fed from the water tub to the rotary tub without being dissolved in the detergent feed unit;
- wherein the detergent feed unit comprises a control unit to drive a pump provided at the detergent feed pipe to sufficiently dissolve the powdered detergent and then feed the dissolved powdered detergent into the rotary tub.
