Abstract

A washing machine of the present invention comprises: a casing; a tub disposed inside the casing, for accommodating water; a drum rotatably provided inside the tub, for accommodating laundry therein; a gasket interposed between the casing and the tub, for preventing the water inside the tub from leaking between the tub and the casing; a gasket nozzle provided at the gasket, for circulating the water and spraying into the drum; a spiral nozzle provided at the gasket, for converting the water into a spiral flow and spraying into the drum; and a turbo wash button for setting or canceling a turbo wash for spraying water through the gasket nozzle when the drum is rotated or for spraying water through the spiral nozzle when the drum is rotated.

First claim

The invention claimed is:

1. A washing machine comprising:
a casing;
a tub disposed inside the casing, for accommodating water;
a drum rotatably provided inside the tub, for accommodating laundry therein;
a gasket interposed between the casing and the tub, for preventing the water inside the tub from leaking between the tub and the casing;
a first gasket nozzle and second gasket nozzle provided at the gasket, for circulating the water and spraying into the drum;
a spiral nozzle provided at the gasket, for converting the water into a spiral flow and spraying into the drum;
a turbo wash button for setting or canceling a turbo wash for spraying water through the gasket nozzles when the drum is rotated or for spraying water through the spiral nozzle when the drum is rotated,
wherein the water sprayed from the first gasket nozzle and the water sprayed from the second gasket nozzle intersect with each other before reaching a posterior wall of the drum;
a course selection unit for selecting a washing course; and
a controller which controls the entire operation of the washing machine under an operation command that the turbo wash button and the course selection unit receives,
wherein when an impossible to set turbo wash washing course is selected through the course selection unit, the controller controls a setting of the turbo wash through the turbo wash button to be disabled even though a user presses the turbo wash button.

2. The washing machine of claim 1 ,
wherein when a basic setting course of turbo wash is selected through the course selection unit, the controller sets the turbo wash basically, and controls the turbo wash canceled if the user presses the turbo wash button.

3. The washing machine of claim 2 ,
wherein when a basic cancellation course of turbo wash is selected through the course selection unit, the controller cancels the turbo wash basically, and controls the turbo wash set if the user presses the turbo wash button.

4. The washing machine of claim 3 , further comprising:
a washing time display unit for displaying an expected washing time,
wherein, when the turbo wash is set through the turbo wash button, the expected washing time displayed in the washing time display unit decreases.

5. The washing machine of claim 4 , wherein the first and second nozzles are disposed symmetrically to each other with respect to the vertical center line H passing through the center of the gasket.

6. The washing machine of claim 3 , wherein
when the turbo wash is set, the controller performs a turbo washing for washing the laundry by rotating the drum, circulating water mixed with washing detergent and spraying into the drum through the first and second gasket nozzles.

7. The washing machine of claim 3 , wherein
when the turbo wash is set, the controller performs a turbo rinsing for rinsing the laundry by rotating the drum, circulating water mixed with rinsing detergent and spraying into the drum through the first and second gasket nozzles.

8. The washing machine of claim 3 , wherein
when the turbo wash is set, the controller performs a penetration rinsing for rotating the drum at a high speed so that the laundry rotates while being attached to the drum, and converting water not mixed with detergent into a spiral flow and then spraying into the drum through the spiral nozzle.

9. The washing machine of claim 3 , wherein the first and second nozzles are disposed symmetrically to each other with respect to the vertical center line H passing through the center of the gasket.
