Abstract

A washing machine having a rinse mode for rinsing laundry placed in a tub of the washing machine. A rinse mode controller controls water supply to the tub and rotation of the tub to carry out a spin dry rinse mode. The spin dry rinse mode includes a first operation during which water is supplied into the tub while the tub is rotated and a second operation during which the supply oft water is stopped and the tub is rotated. The washing machine further includes a unit for detecting the amount of laundry put into the tub. A rinse time change controller controls the time for spin dry rinse mode in accordance with the amount of laundry detected. Thus, time can be saved and water conserved while still effectively rinsing the laundry.

Claims

1. A washing machine, comprising:

a tub for receiving laundry to be washed;

means for supplying water into the tub;

means for rotating the tub;

rinse mode control means for controlling

     1) water supply into the tub and

     2) rotation of the tub so as to carry out a spin dry rinse mode operation, the spin dry rinse mode operation including;

a first operation wherein water is supplied into the tub while the tub is rotated, and

a second operation wherein water is not supplied into the tub and the tub is rotated;

laundry amount detecting means for detecting an amount of laundry placed into the tub; and

rinse time change means for changing a time period of the spin dry rinse mode operation by changing a time period of the second operation in accordance with the amount of laundry detected by laundry amount detecting means.

2. A washing machine, comprising:

a tub for receiving laundry to be washed;

means for supplying water into the tub;

means for rotating the tub;

rinse mode control means for controlling

     1) water supply into the tub and

     2) rotation of the tub so as to carry out a spin dry rinse mode operation, the spin dry rinse mode operation including;

a first operation wherein water is supplied into the tub while the tub is rotated, and

a second operation wherein water is not supplied into the tub and the tub is rotated;

laundry amount detecting means for detecting an amount of laundry placed into the tub; and

rinse time change means for changing a time period of the spin dry rinse mode operation by changing a time period of both the first operation and the second operation in accordance with the amount of laundry detected by laundry amount detecting means.

3. A washing machine, comprising:

a tub for receiving laundry to be washed;

a device for supplying water into the tub;
