Description

  The present invention relates to a drum-type washing and drying machine for washing, rinsing, dehydrating and drying in a rotating drum rotatably disposed in a water tank.

  Conventionally, in this type of drum-type washing machine, when the rotating drum rotates, the laundry in the rotating drum pops upward and hits the opening edge of the aquarium, which is a non-rotating part. Therefore, a configuration for protecting the opening edge has been proposed (for example, see Patent Document 1).

  FIG. 5 is a longitudinal sectional view of a conventional drum-type washing machine described in Patent Document 1, and FIG. 6 is a sectional view of an essential part of the washing machine.

  5 and 6, the rotating drum 5 having a circular clothes insertion port 25 in the front and the water tank 3 that accommodates the rotating drum 5 are inclined from the front side to the back side so as to be inclined from the horizontal direction to the downward direction. It is arranged in the machine housing 2 and has a configuration in which the laundry can be easily put into and out of the rotary drum 5 from the door body 8 provided on the inclined surface where the front surface of the washing machine housing 2 is inclined.

  The water tank 3 is formed in a structure in which a water tank body 3a provided with a bearing 16 and a water tank lid body 3b on the door body 8 side are connected to each other, and the water tank lid body 3b is provided with a water tank opening 14 as a laundry doorway, The inner diameter of the clothing input port 25 of the rotary drum 5 is also set as large as possible to facilitate the operation of putting in and out the clothing.

  Further, the washing machine housing 2 and the front part of the water tub 3 are connected in a watertight manner with a packing member 12 made of a flexible elastic body, and the gap between the front end part of the rotating drum 5 and the front end part of the water tank cover 3b. Is configured to be covered with an annular covering member 11 such as a SUS (stainless steel) material. The packing member 12 is formed in a substantially cylindrical shape, one end is fixed to the flange 6 adjacent to the water tank opening 14 of the water tank lid 3b by a fastening band 28, and the other end is opened to the housing of the washing machine housing 2. It is fitted and held on a mounting plate 10 fixed in the vicinity of the portion 7.

  With the above configuration, when the laundry 13 put into the rotating drum 5 protrudes from the clothing loading port 25 of the rotating drum 5 toward the door body 8 during the washing and dehydrating process, the annular covering member 11 is used. It contacts the central opening 22 and does not contact the packing member 12 or the water tank opening 14.

  However, in the conventional configuration, water droplets are collected at the time of washing or drying at the corner corner of the base of the flange 6 adjacent to the water tank opening 14, and a hole is formed at the corner corner to remove this. It is a general minimum standard configuration to provide a hole in the annular covering member 11 in order to remove the water that has fallen into the annular covering member 11 and is not shown. The conventional configuration should have been designed as such. However, in a general design, water can be drained, but lint generated by the rotation of the laundry during drying accumulates and accumulates in the space formed by the water tank opening 14 and the annular covering member 11 and is badly damaged. As a result, the accumulated lint deforms the annular covering member 11 to reduce the gap B between the rotary drum 5 and the clothing input port 25, and there is a problem that the rotary drum 5 may come into contact with the rotary drum 5.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a drum-type washing / drying machine capable of removing lint together with accumulated water and preventing accumulation of lint.
