Description

  The present invention relates to a drum-type washing machine in which a clothes insertion opening that is opened and closed by a door is provided in front of a washing machine outer box.

  Conventionally, this type of drum type washing machine has a clothes opening for putting clothes in and out of an internal drum formed on the front surface of the outer box, and has a side-opening door (door) that opens and closes the clothes opening. It is provided in the outer box. In ordinary drum-type washing machines, the door (door body) has a left-opening specification, but in general homes, it is used on the opening side when the left-opening door is opened due to restrictions on the installation location. May not be able to locate. As a countermeasure for such a case, a drum type washing machine is known in which a door (door body) can be selected and attached to either a left opening or a right opening in a manufacturing process (for example, Patent Documents). 1).

  FIG. 5 shows an external perspective view of a conventional drum-type washing machine described in Patent Document 1. As shown in FIG.

  In FIG. 5, a substantially circular clothing input port 1 b is formed on the front surface 1 a of the outer box 1 of the drum type washing machine, and this clothing input port 1 b is a door (door body) that can be rotated laterally by a hinge mechanism 60. The operation button 8 is provided on the right side of the door (door body) 2 to open the door (door body) 2 in the closed state.

  FIG. 6 is a front perspective view of an outer case structure of a conventional drum type washing machine.

  In FIG. 6, the outer box 1 is fixed between a pair of left and right side plates 101 and 102 and the upper front edges of the left and right side plates 101 and 102 in a symmetrical manner, and a clothing input port 1 b is formed at the center. A front frame reinforcing plate 103 that also serves as a mounting frame of the door 2, a front reinforcing plate 104 that is fixed between the lower portions of the front edge, and an upper front reinforcing plate 105 that is fixed between the front portions of the upper edge. Etc.

  The door (door body) 2 is attached to the front frame reinforcing plate 103 made of a relatively high strength material such as a steel plate. The door (door body) 2 is attached as shown in FIGS. 5 and 6. Although the door (door body) 2 has a right-opening specification that opens from the right side, the right-opening specification and the left-opening specification can be selected and produced in the manufacturing process.

  FIG. 7: is a schematic front view (b) which shows the door front view (a) of a conventional drum type washing machine, and the opening / closing structure of a door (door body).

  As shown in FIG. 7 (a), the door (door body) 2 is formed in a rectangular shape when viewed from the front, and the door body 51 includes a door frame body 52 having a circular opening formed in the center, and the door frame body. The transparent window body 53 made of a transparent member such as heat-resistant glass attached to the opening 52 and the front surface of the transparent window body 53 are covered, the center is semi-transparent in a substantially circular shape, and the periphery thereof is opaque. It is comprised with the door cover part 54 made from a synthetic resin. Thereby, a see-through window is formed in the center of the door (door body) 2, and the inside of the washing machine can be seen through the see-through window even when the door (door body) 2 is closed.

  A vertical linear portion of one edge (left side in the case of right-opening specification) of the door body 51 (that is, the left side of the rectangle in FIG. 7A) has an arcuate hinge arm 63 shown in FIG. A hinge arm attachment portion 63a to which one end is attached is provided at two locations, upper and lower, and the other end of the hinge arm 63 is fixed to the back surface of the door frame 52 with screws or the like.

  On the other hand, the center point G of the circular opening of the door frame 52 is located on the vertical straight portion of the edge of the door body 51 opposite to the hinge arm attachment portion 63a, that is, on the right side of the rectangle in FIG. A hook-like hook 55 as a locking portion is provided on the horizontal line F passing through the door frame 52 so as to protrude rearward from the door frame body 52, and is substantially symmetric with respect to the hook 55 engaging with the outer box side door latch mechanism 70. The actuating body receiving portion 56 is formed at various positions.

  This door (door body) 2 is substantially vertically symmetrical with respect to the horizontal center line F. That is, the positions of the two hinge arm attachment parts 63a and the two actuating body receiving parts 56 are substantially equally spaced from the horizontal center line F, and the hooks 55 are located on the horizontal center line F.

  Accordingly, even if the door (door body) 2 is rotated 180 degrees on the substantially vertical plane (upside down) about the center point G so that the door (door body) 2 is inverted upside down, the door (door body) 2 is viewed as a vertical line F ′. On the other hand, it is set to be the same as if it was reversed left and right.

  FIG. 8 is a front view showing a mounting structure of a front frame reinforcing plate 103 of a conventional drum type washing machine.

  As shown in FIG. 8, the front frame reinforcing plate 103 is made of a steel plate or the like, and a circular opening 41 corresponding to the clothing insertion port 1b shown in FIGS. Forms an elongated attachment portion 44 in the longitudinal direction. The front frame reinforcing plate 103 is fixed to a flange formed at the front edge portions of the left and right side plates 101 and 102 of the outer box 1 at the mounting portion 44.

  In the right-opening specification, a hinge for attaching the hinge mechanism 60 including the hinge arm 63 described above with reference to FIGS. 7A and 7B between the attachment portion 44 located on the left side and the opening 41. A mounting portion 42 is provided, and on the other hand, a door latch mechanism 70 for locking the hook 55 provided on the door (door body) 2 described above is attached between the mounting portion 44 located on the right side and the opening 41. The door latch mounting portion 43 is provided.

  The outer shape of the front frame reinforcing plate 103 is substantially vertically symmetric with respect to the horizontal center line F, and the positions of the hinge mounting portion 42 and the door latch mounting portion 43 are also vertically symmetric with respect to the horizontal center line F.

  Therefore, as with the door 2, even if the center frame G is rotated 180 degrees in a substantially vertical plane, the front frame reinforcing plate 103 is reversed left and right with respect to the vertical line F ′. By rotating 180 degrees on a substantially vertical surface as described above with the door 2 attached to 103, the right-opening specification is changed to the left-opening specification.

  However, when the front frame reinforcing plate 103 is rotated 180 degrees, the positions of the screw holes and the like for fastening and fixing the front frame reinforcing plate 103 and the side surface plates 101 and 102 may be shifted due to manufacturing variations and the like. Etc. may be hindered.

Therefore, in the conventional example, instead of sharing the mounting hole, the mounting screw position is manufactured separately from the right-opening specification and the left-opening specification from the beginning so that the right specification or the left specification can be identified. As shown, for example, a right-opening specification screw hole 44R, a left-opening specification screw hole 44L, and the like are provided with a marking 45.
