Abstract: A wall-mounted drum-type washing machine includes a rear panel mounted on a wall surface; a tub containing wash water; a rotatable drum in the tub; a driving unit providing power to the drum; a coupling unit on the rear panel coupled to a rotatable driving shaft of the drum; and a disposition portion preventing the driving unit connected to the driving shaft from interfering with the wall surface.

Abstract: A wall-mounted drum type washing machine includes a rear panel mounted on a wall surface; a tub containing washing water, supported by the rear panel; a front panel on the tub; a cover unit covering the front panel; and a detachable detergent box inserted through the cover unit and into the front panel.

Abstract: An exemplary embodiment of the present disclosure relates to a washing machine, and the washing machine includes: a water supply unit which supplies washing water; a dissolving unit which stores air therein, and mixes the supplied washing water and the inside air so that the stored air is dissolved in the supplied washing water; a pressure pump which selectively pressurizes the washing water to be supplied into the dissolving unit from the water supply unit; a pressure sensor which detects pressure of the washing water supplied into the dissolving unit; and a control unit which controls the pressure pump based on information detected by the pressure sensor.

Abstract: A washing machine including a dissolving unit and a bubble generating unit. The dissolving unit includes a hollow outer body that has an open end, a hollow inner body that has an open end. The inner body is disposed in the outer body. The gap between the inner body and the outer body forms a dissolving flow path. A dissolving cap is coupled to one side of the outer body to retain air in the outer body and the inner body. A dissolving inlet port is formed on the dissolving cap to receive water supplied from the outside to the inner body.

Abstract: A washing machine capable of generating and supplying bubbles to laundry during washing and rinsing operations to facilitate removal of detergent and foreign substances from the laundry. A dissolving unit can receive a water supply and contain a volume of air. The dissolving unit provides a water flow path that allows the contained air to dissolve efficiently in the water, thereby providing a water/air mixture to a bubble generating unit. Dissolved air can separate from the water/air mixture in the bubble generating unit and form bubbles, e.g., due to pressure reduction. The bubbles are then supplied to the tub containing the laundry.

Abstract: A washing machine capable of generating bubbles from a water/air mixture and supplying bubbles to the tub to facilitate removal of residual detergent or the like from laundry during washing or rinsing operations. The washing machine has a dissolving unit with an air supply check valve and can receive air from outside of the dissolving unit in accordance with a pressure in the dissolving unit. Air contained in the dissolving unit can be dissolved in water contained therein to produce water/air mixture. A bubble generating unit receives the water/air mixture from the dissolving unit and generates bubbles as the mixture passes along a water flow path and a pressure reduction region in the bubble generating unit.

The dissolving unit includes a hollow outer body that has an open end, and a hollow inner body that has an open end. The inner body is disposed in the outer body. The gap between the inner and the outer body forms a dissolving flow path. The dissolving unit includes flow paths allowing water to mix with air efficiently as water flows through. The bubble generating unit includes a pressure reduction region to reduce pressures of bubbles. Bubbles can be supplied with washing water either to the upper side or the lower side of the tub.

Abstract: An exemplary embodiment of the present disclosure relates to a washing machine including a dissolving unit, and the dissolving unit includes: an outer body which is formed to have a hollow interior, and has one side formed to be opened, and the other side having a drain hole; a dissolving cap which is coupled to one side of the outer body so as to store air therein, and has a dissolving inlet port formed to supply water supplied from the outside into the inner body; and a discharge check valve which is installed at the other side of the outer body, and opens and closes the drain hole.

Abstract: A drainage device for a wall-mounted washing machine includes a drain housing having an inlet at an upper side of a body, a valve wall in the body, a drain and a cap receiver at a lower side of the body opposite to the inlet relative to the valve wall, and a driving unit or actuator receiver on the valve wall, a cap on the cap receiver configured to collect foreign materials; and a driving unit or actuator in the driving unit or actuator receiver, configured to open and close the valve wall. As a result, the user cannot come in contact with the inlet, thereby preventing accidents or burns from components in or near the inlet, such as a heater.
