| 20080250820 | Drain Pump - Drain pump for clothes washing machines, comprising: an impeller having vanes ( | 10-16-2008 |
| 20110214456 | WASHING MACHINE AND DRAIN PUMP THEREOF - Disclosed herein is a drain pump of a washing machine to reduce generation of noise. The drain pump includes a pump case in which a wash water inlet chamber and a drain pump chamber are defined, a wash water inlet port formed at the pump case, to allow wash water to be introduced into the wash water inlet chamber, a wash water outlet port formed at the pump case, to allow the wash water to be discharged from the drain pump chamber, a wash water suction port arranged between the wash water inlet chamber and the drain pump chamber, and an air discharge path arranged at a distance from the wash water suction port between the wash water inlet chamber and the drain pump chamber to allow air inside the wash water inlet chamber to be discharged through the wash water outlet port. | 09-08-2011 |
| 20120090360 | SURGE FILL APPARATUS AND METHOD FOR TOP LOAD WASHING MACHINE - A surge fill apparatus and method for a top load washing machine is disclosed. A top load washing machine includes a cabinet, a tub positioned within the cabinet, and a basket for receiving a wash load rotatably supported within the tub. The washing machine further includes a reservoir in fluid communication with the tub. The reservoir has the capacity to store a volume of wash fluid. The reservoir releases the volume of wash fluid into basket when the volume of wash fluid in the reservoir reaches a threshold level. In this manner, the apparatus and method of the present disclosure provides for a surge of wash fluid to be provided to the top portion of a wash load such that the top portion of the wash load can be cleaned and rinsed more efficiently. | 04-19-2012 |
| 20120118023 | PUMP-TYPE LAUNDRY WASHING MACHINE - This invention is a vertical machine for washing and wringing clothes by mean of a closed pumping circuit which supplies the washing or centrifuging system. The washing system uses a special eductor which produces a cavitation effect above the clothes, combined with a rotary washing system which produces the paused circulation of the clothes; the rotation of the washing system is produced by the same water flow. The centrifuging is made in the inner tub impelling its rotation by means of a turbine, thus the tub rotates over the virtual axis which passes through the center of gravity thereof and the clothes for being wringed, furthermore is used a special annular chamber for auto-balancing. The rotation of the tub over the virtual axis is achieved making float the inner tub by means of the special supports which combine the speed components of any point of the tub. The basic ideas of the above concepts are applied in different practical versions, as well as with modifications to a horizontal axial axis or front-loading washing machine or an industrial washing machine. | 05-17-2012 |
| 20140283561 | METHOD AND A DEVICE FOR CONTROLLED DOSING OF TREATING COMPOSITIONS IN WASHING MACHINES - The present invention provides a method of dispensing a plurality of treating compositions into a multistage automatic washing machine, as well as a dispensing device comprising an associated reservoir for collection of wash liquor and at least two chambers containing a treating composition. Said chambers are activated in response to an input from a sensor. | 09-25-2014 |
| 20160002841 | WASHING MACHINE - A washing machine includes a drum; a door to open and close the drum; a valve to supply water to the door; and a controller to control the valve, during a spin-drying operation, to perform a process to remove residual bubbles from the door. | 01-07-2016 |

| 20140109621 | WASHER FOR SUPPLYING MAGNETIZED WATER - A washer for supplying magnetized water includes a cabinet; a magnetization unit in the cabinet, generating a magnetic field; and a guide unit connected to the magnetization unit, guiding the wash water discharged from the magnetization unit. The magnetization unit includes a housing having a water flow channel through which wash water passes; a hot water supply nozzle connected to one side of the housing, having a hot water supply channel communicating with the water flow channel; and a cold water supply nozzle connected to the one side of the housing, having a cold water supply channel communicating with the water flow channel and separate from the hot water supply channel. | 04-24-2014 |
