Electric washing machine
An electric washing machine according to the present invention performs a washing process for washing laundry without the use of a detergent by generating water streams in an outer tub ( 2 ) containing an electrolyzed liquid produced through electrolysis by an electrolyzing device ( 31 ) when a zero detergent course is selected by a user. The electrolyzing device ( 31 ) is provided as a water treatment unit ( 60 ) attached to a lower portion of an outer side surface ( 66 ) of the outer tub ( 2 ), and includes a thin-box-shaped electrolyzing chamber ( 32 ), a pair of electrodes ( 33 ) supported at opposite edges thereof, and a pair of water communication paths ( 34, 35 ). The pair of water communication paths ( 34, 35 ) are disposed in a vertically juxtaposed relation to connect the outer tub ( 2 ) to the electrolyzing chamber ( 32 ) with the intervention of packings ( 81 ). Thus, an assembling operation and the like can conveniently be performed, and water can efficiently be electrolyzed for use in the washing process.
1. An electric washing machine comprising:
a washing tub to contain laundry;
water motion generating means to generate water motion in the washing tub;
water treatment means to perform a specific treatment on tap water to be supplied into the washing tub or tap water supplied into the washing tub to impart the water with a cleaning capability without addition of a detergent;
storage means which stores therein a sequence for a first washing course in which the laundry is washed by generating water motion in the washing tub which contains a detergent solution prepared by adding the detergent into the tap water, and a sequence for a second washing course in which the laundry is washed without the use of the detergent by generating water motion in the washing tub which contains a cleaning liquid imparted with the cleaning capability by treating the tap water by the water treatment means;
selecting means to allow a user to select the first washing course or the second washing course;
control means to control operations of the water motion generating means and the water treatment means on the basis of the sequence for the washing course selected by the selecting means to perform a washing process in the selected washing course;
load detecting means to detect a load of the laundry; and
information means to notify a detergent amount according to the load detected by the load detecting means,
wherein the control means actuates the load detecting means of the detection of the load and causes the information means to notify the detergent amount according to the detected load in the washing process of the first washing course, and prohibits the information means from notifying the detergent amount in the washing process of the second washing course.
2. An electric washing machine as set forth in claim 1 , wherein the water treatment means comprises a pair of electrodes for electrolysis of the tap water, and produces the cleaning liquid by electrolyzing the tap water through energization of the pair of electrodes.
3. An electric washing machine as set forth in claim 1 , further comprising:
second information means to notify that no detergent is added,
wherein the control means actuates the second information means in the washing process of the second washing course.
4. An electric washing machine as set forth in claim 3 ,
wherein the water treatment means comprises a pair of electrodes for electrolysis of the tap water, and produces the cleaning liquid by electrolyzing the tap water through energization of the pair of electrodes.
5. An electric washing machine comprising:
a washing tub to contain laundry;
water motion generating means to generate water motion in the washing tub;
water treatment means to perform a specific treatment on tap water to be supplied into the washing tub or tap water supplied into the washing tub to impart the water with a cleaning capability without addition of a detergent;
storage means which stores therein a sequence for a first washing course in which the laundry is washed by generating water motion in the washing tub which contains a detergent solution prepared by adding the detergent into the tap water, and a sequence for a second washing course in which the laundry is washed without the use of the detergent by generating water motion in the washing tub which contains a cleaning liquid imparted with the cleaning capability by treating the tap water by the water treatment means;
selecting means to allow a user to select the first washing course or the second washing course;
control means to control operations of the water motion generating means and the water treatment means on the basis of the sequence for the washing course selected by the selecting means to perform a washing process in the selected washing course;
load detecting means to detect a load of the laundry; and
adding means to add the detergent in an amount according to the load detected by the load detecting means,
wherein the control means actuates the load detecting means to detect the load and causes the adding means to add the detergent in the amount according to the detected load in the washing process of the first washing course, and prohibits the adding means from adding the detergent in the washing process of the second washing course.
6. An electric washing machine as set forth in claim 5 ,
wherein the water treatment means comprises a pair of electrodes for electrolysis of the tap water, and produces the cleaning liquid by electrolyzing the tap water through energization of the pair of electrodes.
