Definitions

  • the present invention relates to a drum-type laundry machine which is adapted to accommodate and wash laundry in a drum thereof.
  • a drum-type laundry machine which is adapted to accommodate and wash laundry in a generally cylindrical drum rotatable about a generally horizontal axis.
  • the laundry machine of this type comprises, for example, an outer tub surrounding the drum.
  • the laundry machine is adapted to rotate the drum with a predetermined amount of water contained in the outer tub, and repeat such an operation (slam-washing operation) as to lift the laundry in the drum by baffles projecting inwardly of the interior surface of the drum and drop the laundry from a certain height toward the surface of the water by gravity.
  • the drum and the outer tub are disposed in a housing with their opposite end faces oriented anteriorly and posteriorly of the laundry machine.
  • An outer lid to be opened and closed for loading and unloading the laundry is provided on a front face of the housing.
  • An inner lid and a drum lid are provided on front end faces of the outer tub and the drum, respectively. With the outer lid, the inner lid and the drum lid being all open, the laundry is taken into and out of the drum from the front side of the drum-type laundry machine.
  • drum-type laundry machine having an outer lid provided on a top face of a housing thereof (see, for example, Sanyo Electric's "Laundry Machine and Clothes Dryer Catalog (2002 winter) ", p. 1-6) .
  • a drum and an outer tub are disposed in the housing, for example, with their opposite end faces being oriented laterally.
  • An inner lid and a drum lid are provided on circumferences of the outer tub and the drum, respectively.
  • the user can insert his/her hands into the drum from the diagonally upper side with the outer lid, the inner lid and the drum lid being all open, and assume an easy attitude for taking the laundry in and out of the drum.
  • the housing has an anteroposteriorly elongated opening to be covered and uncovered by the outer lid for facilitating the loading and unloading of the laundry. Accordingly, the outer lid needs to have an anteroposteriorly elongated shape.
  • the outer lid has a foldable structure, so that the opening of the housing can widely be opened by compactly folding the outer lid rearwardly of the housing.
  • the outer lid includes a rear lid which covers a rear portion of the opening of the housing, and a front lid which covers a front portion of the opening of the housing.
  • the rear lid is pivotally attached along its rear edge to a top face of the housing
  • the front lid is pivotally attached along its rear edge to a front edge of the rear lid.
  • the user holds a handle provided on the front lid, and slides the front lid rearward while lifting a rear portion of the front lid.
  • the outer lid is folded with the front lid and the rear lid thereof projecting upward.
  • the front lid should anteroposteriorly be slid for a long distance by holding the handle of the front lid for covering and uncovering the opening of the housing, because the opening of the housing has an anteroposteriorly elongated shape (particularly because the opening is inclined for easy loading and unloading of the laundry and, hence, has a greater length). Therefore, it is desirable to provide a construction which allows for easier opening and closing of the outer lid.
  • the outer lid is folded to be opened, and then the inner lid is opened. At this time, the inner lid is opposed to the front side of the folded outer lid.
  • the outer lid should be adapted to be tilted rearward in a folded state. With this arrangement, however, there is a possibility that the outer lid hits against a faucet projecting from a wall for supplying water into the drum-type laundry machine, if the drum-type laundry machine is installed with a rear face of the housing thereof fitted along the wall.
  • a drum-type laundry machine (1; 100) which comprises:
  • the lid is, for example, accommodated in the housing so not as to project out of the housing, unlike the conventional drum-type laundry machine having the two lids which are foldable to project upward from the top face of the housing. Therefore, there is no possibility that the lid of the drum-type laundry machine hits against a faucet projecting from a wall for supplying water into the drum-type laundry machine, even if the drum-type laundrymachine is installed with a rear face of the housing thereof fitted along the wall. Thus, the opening and closing of the lid can more advantageously be achieved.
  • the drum-type laundry machine (1; 100) of claim 1 is characterized in that: the top face (2A; 211; 212) of the housing (2; 200, 210) includes an oblique face (2B; 212) inclined forwardly downward; the inlet opening (4) extends from a front portion of the oblique face to a rear portion of the top face; and the slide lid (31; 38) is slid rearward from a front edge of the inlet opening to uncover the inlet opening, and is slid forward to the front edge of the inlet opening to cover the inlet opening.
  • the lid (slide lid) needs to have an anteroposteriorly elongated shape for covering theanteroposteriorlyelongatedopening whichextendsfrom the top face to the oblique face of the housing.
  • the lid is prevented from projecting from the housing, for example, by accommodating the lid in the housing. Therefore, even if the drum-type laundry machine is installed with the rear face of the housing thereof fitted along the wall, the outer lid of the drum-type laundry machine is effectively prevented from hitting against the faucet projecting from the wall for supplying water into the drum-type laundry machine, as compared with the conventional drum-type laundry machine which has the two lids foldable to project upward from the top face of the housing.
  • the opening and closing of the lid can more advantageously be achieved.
