Abstract

A washing machine and a method of controlling such, wherein the washing of laundry articles can be performed according to user preference. According to the invention, a plurality of washing factors, which are selected by the user, are stored in an accumulated manner in a memory during a manual washing operation of the washing machine. In an automatic washing operation of the washing machine, the washing factors stored in the memory when the manual washing operation was performed are analyzed for recognition of those factors which the user likes best. A plurality of washing factors are inferred from a plurality of washing information regarding conditions in the washing bath. Then, self-learning is performed based on the inferred washing factors and the recognized washing factors to determine a plurality of final washing factors. The automatic washing operation is performed according to the determined final washing factors.

Claims

1. A washing machine comprising:

key signal generating means for generating a washing mode signal to select one of automatic and manual washing operations and a plurality of washing factors necessary to perform the manual washing operation according to user selections;

washing information sensing means for sensing a plurality of washing information regarding conditions in a washing bath;

memory means for storing in an accumulated manner the plurality of washing factors from said key signal generating means which are selected by the user whenever the manual washing operation is performed;

control means for recognizing one of the manual and automatic washing operations in response to the washing mode signal from said key signal generating means, for controlling the manual washing operation in accordance with the plurality of washing factors from said key signal generating means and the plurality of washing information from said washing information sensing means, for inferring a plurality of washing factors from the plurality of washing information from said washing information sensing means, and for controlling the automatic washing operation according to the inferred washing factors and the plurality of washing factors stored in said memory means when the manual washing operation was performed;

load means for executing the automatic and manual washing operations of the washing machine; and

load driving means for driving said load means in the automatic washing operation or the manual washing operation under the control of said control means.

2. A washing machine as set forth in claim 1, wherein said plurality of washing factors include a level of washing water, a washing time, a number of rinsing times, and a hydrating time.

3. A washing machine as set forth in claim 1, wherein said plurality of washing information include a level of washing water, an amount of laundry articles, and a turbidity of the washing water in said washing bath.

4. A washing machine as set forth in claim 1, wherein said washing information sensing means includes:

a level sensor for sensing the level of washing water in said washing bath;

a turbidity sensor for sensing the turbidity of the washing water in said washing bath; and

a laundry amount sensor for sensing the amount of laundry articles in said washing bath.

5. A washing machine as set forth in claim 1, wherein said memory means includes an EEPROM.

6. A method of controlling a washing machine, comprising the steps of:

generating a washing mode signal to select one of automatic and manual washing operations of the washing machine according to user selection;

if the manual washing operation is indicated by the mode select signal, performing the manual washing operation in accordance with a plurality of washing factors which are selected by the user and a plurality of washing information regarding conditions in a washing bath and storing the plurality of washing factors in an accumulated manner in a memory; and

if the automatic washing operation is indicated by the mode select signal, inferring a plurality of washing factors from one of the plurality of washing information, analyzing the washing factors stored in said memory when the manual washing operation was performed to recognize those which the user prefers, performing self-learning based on the inferred washing factors and the recognized washing factors to determine a plurality of final washing factors, and performing the automatic washing operation according to the determined final washing factors.

7. A method of controlling a washing machine, as set forth in claim 6, wherein said one of the plurality of washing information used in the inference of the washing factors is an amount of laundry articles in the washing bath.

8. A method of controlling a washing machine, as set forth in claim 6, wherein said plurality of washing factors include a level of washing water, a washing time, a number of rinsing times, and a hydrating time.

9. A method of controlling a washing machine, as set forth in claim 6, wherein said plurality of washing information include a level of washing water, an amount of laundry articles and a turbidity of the washing water in said washing bath.

10. A method of controlling a washing machine, as set forth in claim 6, wherein the step of storing the washing factors in the manual washing operation includes the steps of:

accumulating a frequency of the washing machine in a region of the memory corresponding to the one of the plurality of washing information for the inference of the washing factors; and

storing the plurality of washing factors which are selected by the user in the accumulated manner in said memory region.

11. A method of controlling a washing machine, as set forth in claim 10, further including the step of determining the inferred washing factors as the final washing factors when a total frequency corresponding to the one of the plurality of washing information is smaller than a predetermined reference frequency.

12. A method of controlling a washing machine, as set forth in claim 6, wherein the recognized washing factors are the most frequently used of the washing factors stored during the manual washing operation.

13. A method of controlling a washing machine, as set forth in claim 6, further including the steps of calculating accounting ratios by dividing frequencies of the recognized washing factors by corresponding total frequencies of the washing machine and determining the inferred washing factors or the recognized washing factors as the final washing factors according to the calculated accounting ratios.

14. A method of controlling a washing machine, as set forth in claim 13, further including the step of determining the inferred washing factors as the final washing factors when the accounting ratios of the recognized washing factors are smaller than predetermined reference accounting ratios and the recognized washing factors are smaller than the inferred washing factors.

15. A method of controlling a washing machine, as set forth in claim 14, wherein the predetermined reference accounting ratios are previously defined for determination of the final washing factors in the case where it is difficult to recognize user preference.

16. A method of controlling a washing machine, as set forth in claim 13, further including the step of determining the recognized washing factors as the final washing factors when the accounting ratios of the recognized washing factors are greater than or equal to predetermined reference accounting ratios and the recognized washing factors are greater than or equal to the inferred washing factors.

17. A method of controlling a washing machine, as set forth in claim 16, wherein said predetermined reference accounting ratios are previously defined for determination of the final washing factors in the case where it is difficult to recognize user preference.
