Abstract

Disclosed is a drum type laundry machine, including a casing, a control panel, an outer drum, an inner drum, a water inlet system, a water drainage system, a driving system, washing balls, a storage chamber disposed on the bottom of the outer drum, a circulation piping system connecting the storage chamber with the inner drum, and an outlet of the circulation pipe system leading to the inner drum and provided on an annular opening of the inner drum. The washing procedure of the laundry process described herein also includes a washing step while the washing balls circulate in the inner and outer drum, and a collecting step of the washing balls. The drum type laundry machine of the present invention can save water and electricity and can reduce pollution.

First claim

What is claimed is:

1. A drum type laundry machine comprising:
a motor ( 14 );
an outer drum ( 5 );
an inner drum ( 6 ) disposed in the outer drum ( 5 );
a plurality of washing balls ( 7 ),
a circulation pipe line ( 18 ); and
a control device,
wherein a central axis of the inner drum and the outer drum is disposed laterally,
wherein said inner drum ( 6 ) is driven to rotate by the motor ( 14 ),
wherein a drum wall of said inner drum ( 6 ) is provided with a plurality of through holes passing through the drum wall, wherein the diameter of said washing balls ( 7 ) is less than the diameter of at least parts of said through holes of said inner drum ( 6 ),
wherein one end of said circulation pipe line ( 18 ) is connected to the inside of said outer drum ( 5 ) via the lower side of said outer drum ( 5 ), and
wherein the other end of said circulation pipe line ( 18 ) is connected to said inner drum ( 6 ), said circulation pipe line ( 18 ) is provided with a circulation pump ( 4 ) by which said washing balls ( 7 ) are delivered to the inside of said inner drum ( 6 ) so that said washing balls ( 7 ) circulate between said inner drum ( 6 ) and said outer drum ( 5 ) via said circulation pipe line ( 18 ), and
wherein the control device is configured to turn on the circulation pump ( 4 ) after said inner drum ( 6 ) rotates for a first predetermined time when clothes washing and is configured to turn off the circulation pump ( 4 ) when the clothes washing is finished and then to cause motor ( 14 ) to rotate said inner drum ( 6 ) for a second predetermined time.

2. The drum type laundry machine according to claim 1 , wherein the lower portion of said outer drum ( 5 ) is provided with a storage chamber ( 19 ) for receiving said washing balls ( 7 ), said circulation pipe line ( 18 ) is connected to the lower portion of said outer drum ( 5 ) via said storage chamber ( 19 ).

3. The drum type laundry machine according to claim 2 , further comprising a drainage pipe ( 12 ) connected with said storage chamber ( 19 ), wherein said drainage pipe ( 12 ) is provided with a drainage solenoid valve ( 3 ); a filter screen cover for blocking said washing balls ( 7 ) and draining water is provided between said drainage solenoid valve ( 3 ) and said storage chamber ( 19 ).

4. The drum type laundry machine according to claim 1 , wherein said circulation pipe line ( 18 ) is provided with a circulation solenoid valve ( 2 ) located on a water inlet side of said circulation pump ( 4 ).

5. The drum type laundry machine according to claim 1 , wherein the diameter of said washing balls ( 7 ) is 2 mm-4 mm.

6. The drum type laundry machine according to claim 1 , wherein said washing balls ( 7 ) are polymer globular particles of which surfaces have at least one projection or are porous.

7. The drum type laundry machine according to claim 1 , wherein the front of said inner drum ( 6 ) is provided with an opening ( 15 ) to which an opening of the other end of said circulation pipe line ( 18 ) is disposed oppositely, so that said circulation pipe line ( 18 ) is connected to said inner drum ( 6 ).

8. The drum type laundry machine according to claim 1 , wherein the control device comprises a start button for taking out the washing balls ( 7 ); when the start button is pressed, said control device turns on the circulation pump ( 4 ).

9. The drum type laundry machine according to claim 1 , wherein said circulation pipe line ( 18 ) is connected to the upper portion of said inner drum ( 6 ), said circulation pump ( 4 ) pumps said washing balls ( 7 ) and water flow from said circulation pipe line ( 18 ) into said inner drum ( 6 ).

10. The drum type laundry machine according to claim 1 , wherein the upper end of said circulation pipe ( 18 ) is connected to an annular opening ( 15 ) of the inner drum ( 6 ) so as to let the water pumped by the circulation pump ( 4 ) and washing balls ( 7 ) enter the inner drum ( 6 ).

11. The drum type laundry machine according to claim 1 , wherein the apparatus is adapted to clean the washing balls after performing a plurality of washing procedures.

12. The drum type laundry machine according to claim 1 , wherein said circulation pipe line ( 18 ) is provided with a circulation solenoid valve ( 2 ), and the control device performs the following program: injecting water without clothes in the drum, and then opening the circulation solenoid valve ( 2 ) and the circulation pump ( 4 ) to wash the washing balls ( 7 ) circularly.

13. The drum type laundry machine according to claim 12 , wherein the laundry machine further comprises a drainage pipe ( 12 ) provided with a drainage solenoid valve ( 3 ) and a filter screen cover for blocking said washing balls ( 7 ), and the control device performs the following program: ejecting the washing balls during draining by opening the drainage solenoid valve ( 3 ) and the filter screen thereof after turning off the solenoid valve ( 2 ) and the circulation pump ( 4 ), in order to dry or disinfect the washing balls ( 7 ).
