By making it longer than the length of the body, the pivotable angle of the second lid can be increased.

  Hereinafter, the drum type washing machine of the present invention will be described in detail with reference to the illustrated embodiments.

  FIG. 1 is a schematic longitudinal sectional view of a drum type washing machine according to an embodiment of the present invention.

  The drum type washing machine includes an outer box 1, a water tank 2 disposed in the outer box 1, a rotating drum 3 rotatably disposed in the water tank 2, and a drive mechanism for rotating the rotating drum 3. 4 and a suspension 5 that elastically supports the water tank 2.

  A substantially rectangular opening 6 is provided on the front surface of the outer box 1, and the laundry can be taken in and out through the opening 6 of the outer box 1. The opening 6 of the outer box 1 is opened and closed by an external door 7 slidable in the vertical direction with respect to the outer box 1. The sliding of the external door 7 is performed by the user's hand. That is, the external door 7 is a manual slide door. For example, when opening the opening 6 of the outer box 1, the user manually slides the external door 7 in the direction of the arrow. The opening 6 is an example of a first opening, and the external door 7 is an example of a first lid.

  The water tank 2 has a bottomed cylindrical shape, and is arranged in a horizontal direction with a slight inclination so that the opening 8 faces slightly upward. The opening 8 of the water tank 2 and the opening 6 of the outer box 1 are spaced apart from each other. Further, a substantially elliptical hinge-type lid body 9 is rotatably attached to the front surface of the water tank 2. A plate-shaped elastic member 10 is disposed on the radially outer side of the opening 8 of the water tank 2. Since the elastic member 10 is located between the opening 8 of the water tank 2 and the opening 6 of the outer box 1, the user passes between the opening 8 of the water tank 2 and the opening 6 of the outer box 1. The inside of the outer box 1 cannot be seen (see FIG. 3B). In addition, it is an example of the 2nd opening part of the said opening part 8, and the cover body 9 is an example of a 2nd cover body.

  The rotating drum 3 is arranged so that the rotating shaft of the rotating drum 3 is inclined so that the rear side (the back side of the rotating drum 3) is lowered by an angle of 5 ° to 30 ° with respect to the horizontal direction. Thereby, when the user stands on the front side of the drum type washing machine and operates the drum type washing machine, the user can easily look down to the back of the rotating drum 3 while looking down.

  In addition, 19 of FIG. 1 is a control apparatus which controls operation | movement of the said drum type washing machine.

  In FIG. 2, the end elevation of the schematic longitudinal cross-section of the said water tank 2 and the cover body 9 is shown.

  The opening 8 of the water tank 2 has a convex shape with respect to the front surface of the water tank 2, and a convex sealing member 14 is fixed from the inner peripheral surface of the opening 8 to the edge of the opening 8. .

  The lid 9 is in contact with the transparent window glass 11 projecting into the water tank 2, the front lid 12 in contact with the front surface of the outer edge portion of the window glass 11, and the rear surface of the outer edge portion of the window glass 11. A rear lid 13 is provided. The window glass 11 is sandwiched between a front lid 12 and a rear lid 13. The rear lid 13 is formed in a concave shape so as to cover the front end portion of the seal member 14.

  FIG. 3A shows a schematic front view of the opening 6 of the outer box 1. FIG. 3B shows an end view of a schematic cross section of the front portion of the drum type washing machine. In FIG. 3A, the outer peripheral edge of the seal member 14 in a plane including the tip (front end) of the seal member 14 is indicated by a dotted line.

  As shown in FIG. 3A, the length L1 of the lid body 9 in the direction substantially perpendicular to the rotation axis of the lid body 9 is the outer box 1 in the direction substantially perpendicular to the rotation axis of the lid body 9. The opening 6 is shorter than the length L3. In other words, the length L3 of the opening 6 of the outer box 1 in the direction substantially perpendicular to the rotation axis of the lid body 9 is the lid in the direction substantially perpendicular to the rotation axis of the lid body 9. It is longer than the length L1 of the body 9. The length L2 of the lid body 9 in the direction substantially parallel to the rotation axis of the lid body 9 is greater than the length L1 of the lid body 9 in the direction substantially perpendicular to the rotation axis of the lid body 9. And shorter than the inner diameter of the seal member 14. Further, the outer diameter of the window glass 11 is also longer than the inner diameter of the seal member 14.

  As shown in FIG. 3B, a hinge portion that pivotally connects the lid body 9 to the water tank 2 at one edge of the lid body 9 in a direction substantially perpendicular to the pivot axis of the lid body 9. 15, and a handle portion 16 for opening and closing the lid body 9 and a latch portion 17 interlocking with the handle portion 16 are provided on the other edge of the lid body 9. Although not shown, a latching claw is provided at the tip of the latch portion 17.

  In addition, since the opening 8 of the water tank 2 has a convex shape with respect to the front surface of the water tank 2, a space having a height h is obtained on the radially outer side of the opening 8 of the water tank 2. The lid lock 18 is disposed in this space, and the above-mentioned locking claw of the latch portion 17 is locked to the lid lock 18. More specifically, the latching claw of the latch portion 17 is latched by the latching portion 20 in the lid lock 18. When the latching claw of the latch part 17 is latched by the latching part 20 in the lid lock 18, a coil spring (not shown) in the lid lock 18 urges the latching part 20 toward the inside of the water tank 2. It is supposed to be.

  Note that the locking claw of the latch portion 17 with respect to the locking portion 20 can be released by operating the handle portion 16. Further, the lid 9 can be locked by the control device 19. That is, even if the control device 19 sends a control signal to the lid lock 18 and the handle portion 16 is operated, the latching claw of the latch portion 17 with respect to the latching portion 20 can be prevented from being released.

  According to the drum type washing machine having the above configuration, as shown in FIG. 1, the external door 7 slides up and down with respect to the outer box 1 to open and close the opening 6 of the outer box 1. Unlike the door of the type, the external door 7 does not protrude forward of the outer box 1. Therefore, this washing machine can be used in a small empty space without requiring a large space in front of the outer box 1.

  Further, since the external door 7 does not protrude forward of the outer box 1, when the laundry is taken in and out, the external door 7 does not get in the way of the user, and the workability when the laundry is taken in and out can be improved.

  Further, as shown in FIG. 3A, the length L2 of the lid body 9 in the direction substantially parallel to the rotation axis of the lid body 9 is the lid in the direction substantially perpendicular to the rotation axis of the lid body 9. Since the length is shorter than the length L1 of the body 9, the length L4 of the opening 6 of the outer box 1 in the direction substantially parallel to the rotation axis of the lid body 9 can be shortened. As a result, the sliding distance of the external door 7 is shortened, so that the product height can be lowered, the product installation property can be improved, and the manufacturing cost can be reduced.

  Further, the length L2 of the lid body 9 in the direction substantially parallel to the rotation axis of the substantially elliptical lid body 9 is such that the length of the lid body 9 in the direction substantially perpendicular to the rotation axis of the lid body 9 is Since it is shorter than the length L1, the center position of the substantially elliptical lid 9 can be brought closer to the top surface of the outer box 1. That is, the center position of the lid body 9 can be made higher than the center position of a perfect circle-shaped lid body having the same area as the substantially elliptical lid body 9. Therefore, the center position of the opening 8 of the water tank 2 can be increased. Therefore, the operator can easily put in and take out the laundry in the opening 8 of the water tank 2.

  Moreover, since the center position of the lid 9 can be increased, the center position of the opening 6 of the outer box 1 can be increased. That is, the distance between the upper end of the opening 6 of the outer box 1 and the top surface of the outer box 1 can be shortened.

  Further, since the center position of the opening 6 of the outer box 1 can be raised and the center position of the opening 8 of the water tank 2 can be raised, the user can open and close the lid 9 and put in and out the laundry while standing. Can be easily performed.

  In addition, the length L3 of the opening 6 of the outer box 1 in the direction substantially perpendicular to the rotation axis of the lid 9 is such that the length of the lid 9 in the direction substantially perpendicular to the rotation axis of the lid 9 is Since the length is longer than the length L1, the pivotable angle of the lid body 9 can be increased. That is, the so-called open dimension of the external door 7 can be increased.

  In addition, since the lid body 9 has a substantially elliptical shape, the feeling of pressure that the user receives from the lid body 9 can be reduced.

  Further, since the rear lid 13 is formed in a concave shape and covers the front end portion of the sealing member 14, the forward projection amount of the lid body 9 when the opening 8 of the water tank 2 is closed is reduced. Therefore, the depth of the product can be reduced.

  Further, since the forward projection amount of the lid body 9 when the opening 8 of the water tank 2 is closed is small, the distance between the opening 6 of the outer case 1 and the opening 8 of the water tank 2 is shortened. Therefore, the user can easily reach the back of the rotary drum 3 and the laundry can be easily taken out.

  Further, the length L1 of the lid body 9 is made longer than the length L2 of the lid body 9, and a hinge is provided at one edge of the lid body 9 in a direction substantially perpendicular to the rotation axis of the lid body 9. Since the part 15 is provided, the freedom degree of the shape of the hinge part 15 can be improved.

  Further, the length L1 of the lid body 9 is made longer than the length L2 of the lid body 9, and a handle is attached to the other edge of the lid body 9 in a direction substantially perpendicular to the rotation axis of the lid body 9. Since 16 and the latch part 17 are provided, the freedom degree of the shape of the handle part 16 and the latch part 17 can be improved.

  Moreover, since the lid lock 18 is disposed in a space having a height h outside the opening 8 of the water tank 2 in the radial direction, the depth of the product can be prevented from increasing.

  In the embodiment described above, the substantially elliptical lid body 9 is used. However, for example, a substantially rectangular lid body may be used. Needless to say, the length of the lid in a direction substantially parallel to the rotation axis of the lid is shorter than the length of the lid in a direction substantially perpendicular to the rotation axis of the lid. To do.

  The present invention can be applied to a drum type washing machine having no drying function or a drum type washing machine having a drying function.
