Abstract
Disclosed herein is a washing machine capable of suppressing noise during spin-drying caused by a pressure difference in a tub. The washing machine may include a case comprising a laundry loading/unloading opening through which laundry is introduced, a door mounted at the case to open or close the laundry loading/unloading opening, a tub disposed inside the case, a drum rotatably disposed inside the tub, and an air inflow channel configured to guide air to flow toward a central portion of the drum in which a pressure decreases while the drum rotates.
Claims18
A washing machine comprising:
- a case comprising a laundry loading/unloading opening through which laundry is introduced;
- a door mounted at the case to open or close the laundry loading/unloading opening;
- a tub disposed inside the case;
- a drum rotatably disposed inside the tub;
- and
- an air inflow channel configured to guide air between the drum and the tub to flow toward a central portion of the drum in which a pressure decreases while the drum rotates,
- wherein the tub comprises:
- an opening connected to the laundry loading/unloading opening,
- an end wall facing the opening, wherein a rib radially extending from a center of the end wall is provided on an outer surface of the end wall, and
- a cover member mounted on an outer surface of the end wall and includes a rib-fitting part fitted to the rib,
- wherein the air inflow channel comprises an air inlet formed at one portion of the end wall, and
- wherein the cover member is configured to guide air into the air inlet.
A washing machine comprising:
- a case comprising a laundry loading/unloading opening through which laundry is introduced;
- a door mounted at the case to open or close the laundry loading/unloading opening;
- a tub disposed inside the case and having an opening connected to the laundry loading/unloading opening, wherein a rib radially extending from a center of an end wall is provided on an outer surface of the end wall;
- a drum rotatably disposed inside the tub;
- and
- an air inlet disposed at one surface of the tub or one surface of the door to allow air between the drum and the tub to flow to a central portion of the drum while the drum rotates,
- a cover member connected to the air inlet to constitute an air inflow channel configured to guide air and includes a rib-fitting part fitted to the rib.
A washing machine comprising:
- a case comprising a laundry loading/unloading opening through which laundry is introduced;
- a tub disposed inside the case, and comprising an end wall facing the laundry loading/unloading opening and a main body wall that is cylindrical, wherein a rib radially extending from a center of the end wall is provided on an outer surface of the end wall;
- a drum rotatably disposed inside the tub and having a circumferential wall;
- an air inflow channel configured to guide air between the drum and the tub toward a central portion of the drum while the drum rotates;
- and
- a cover member configured to constitute an air inflow channel configured to guide air and includes a rib-fitting part fitted to the rib.
