Abstract

An inventive electric washing machine is configured so that a gas to be used for performing a specific process (decontamination process) on laundry is prevented from leaking to the outside. In the electric washing machine, a packing ( 120 ) to be brought into intimate contact with a door ( 12 ) for sealing a gap defined between the door ( 12 ) and a peripheral edge of an outer tub opening ( 118 ) when the door ( 12 ) is closed is opposed to a housing opening ( 14 ) with a space ( 129 ) defined between a lower edge portion of the housing opening ( 14 ) and the packing ( 120 ). If the door ( 12 ) is closed with laundry protruding through the lower edge portion of the housing opening ( 14 ), the protruding laundry is caught between the door ( 12 ) and the packing ( 120 ), so that the packing ( 120 ) is not brought into intimate contact with the door ( 12 ). If ozone is supplied into an outer tub ( 21 ) in this state, the ozone flows toward the housing opening ( 14 ) through a gap between the door ( 12 ) and the packing ( 120 ) at which the laundry is caught. However, the ozone flows into the space ( 129 ) (as indicated by a broken-line arrow X) and is retained in a housing ( 11 ) to be thereby prevented from leaking to the outside.

Claims (20)

1. An electric washing machine comprising:

a housing;

a cover member defining a front wall of the housing and having an access opening through which laundry is loaded and unloaded into and out of the housing;

a laundry containing tub disposed in the housing and having a tub opening provided in association with the access opening so that the laundry is loaded therein through the access opening and the tub opening to be contained therein;

a door which opens and closes the access opening and the tub opening; and

a packing which covers a peripheral edge of the tub opening and is brought into intimate contact with the door for sealing a gap defined between the door and the peripheral edge of the tub opening when the door is closed, the packing being opposed to the access opening with a space defined between a lower edge portion of the access opening and the packing wherein the packing has a shutter portion which cover the space when the door is opened, and uncovers the space when the door is closed.

2. The electric washing machine according to claim 1 , wherein the cover member has a plurality of ribs provided adjacent the lower edge portion of the access opening thereof as extending downward and arranged at intervals along the space defined between the packing and the lower edge portion of the access opening.

3. The electric washing machine according to claim 2 , wherein the door has a guide wall extending toward the space.

4. The electric washing machine according to claim 3 , further comprising an inclined wall disposed below the space and inclined forwardly downward to be connected to the cover member.

5. The electric washing machine according to claim 2 , further comprising an inclined wall disposed below the space and inclined forwardly downward to be connected to the cover member.

6. The electric washing machine according to claim 1 , wherein the door has a guide wall extending toward the space.

7. The electric washing machine according to claim 6 , further comprising an inclined wall disposed below the space and inclined forwardly downward to be connected to the cover member.

8. The electric washing machine according to claim 1 , further comprising an inclined wall disposed below the space and inclined forwardly downward to be connected to the cover member.

9. An electric washing machine comprising:

a housing;

a cover member defining a front wall of the housing and having an access opening through which laundry is loaded and unloaded into and out of the housing;

a laundry containing tub disposed in the housing and having a tub opening provided in association with the access opening so that the laundry is loaded therein through the access opening and the tub opening to be contained therein; wherein a packing has a shutter portion which cover the space when the door is opened, and uncovers the space when the door is closed;

a door which opens and closes the access opening and the tub opening;

wherein the cover member has a first engagement portion provided adjacent a lower edge portion of the access opening;

wherein the door has a second engagement portion to be engaged with the first engagement portion when the door is closed.
