Description

  The present invention relates to a drum-type washing machine having a packing member provided so that water in a water tank does not leak inside or outside a main body.

In the drum type washing machine, a rotating drum that houses the washing machine and a water tank that contains the rotating drum are installed horizontally or at an angle to the ground.

  However, in such a structure, water stored in the water tank leaks into or out of the washing machine during washing or dehydration.

  Therefore, a cylindrical packing member is attached between the opening of the water tub and the opening for taking in and out the laundry provided on the outer plate. The exterior plate side of the packing member is sandwiched between the exterior plate and the annular attachment plate by attaching an annular attachment plate from the back side of the exterior plate.

With such a structure, the packing member can prevent water leakage into and out of the washing machine main body (see, for example, Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
1 and 2, a rotary drum 4 having a plurality of holes 2 in a peripheral wall and a plurality of baffles 3 projecting from the inner periphery inside the main body 1 having a gently receding curved front surface, and the rotary drum. Is disposed.

  The operation of the drum type washing machine of this embodiment will be described below. During the washing operation, water is stored in the lower part of the outer tub 4 and the rotating drum 3 is rotated. Clothing or the like stored in the rotating drum 3 is lifted upward by the baffle 2, released from the baffle at a predetermined position, and dropped onto the water surface stored in the outer tub 4, so-called “shaking” is performed. Is.

  When the washing process is completed, a dehydration process is performed through a rinsing process and the like. In this dehydration step, the water in the water tank 5 is drained, and the rotating drum 4 is rotated at a high speed. Therefore, the moisture of the clothes is scattered around by centrifugal force, and then flows out from the hole 2 of the rotating drum 4 into the water tank 5 and is discarded from a predetermined drainage path.

  In a device having a drying function, hot air is supplied into the rotary drum 4 while rotating the rotary drum 4 at a low speed after the dehydration step. In the case where the circulation system is adopted, the high-humidity air after being dried goes out from the hole 2 of the rotating drum 4 and is then cooled and dehumidified. The dehumidified air is heated by the heater to become warm air, and then returns to the inside from the back of the rotating drum 4 again.

The rotational axis of the rotary drum 4 is set to be inclined so that the front is high, and therefore, the drum opening 6 of the rotary drum 4 is released above the gentle front curved surface of the main body 1. . In addition, the drum opening 6 of the drum 4 is inclined by about 30 degrees with respect to the vertical, and these elements facilitate the entry and exit of clothing from the rotating drum 4.

  The drum opening 6 of the rotary drum 4 is connected to an opening member 8 having a front opening 8a for putting clothes on a curved panel member 7 formed of plastics of the main body 1, and this opening member. 8 is opened and closed by a lid 9.

  The main body 1 includes divided sheet metal left and right side plates 10, a detachable back plate 11, a plurality of sheet metal connection plates that connect the left and right side plates, a top plate 12 made of synthetic resin, and the panel member 7. ing.

  A circular front plate opening 14 corresponding to the drum opening 6 of the rotary drum 4 is formed in the front plate 13 located inside the panel member 7 among the plurality of connecting plates. The front plate 13 is covered with a panel member 7 at the front.

  The aquarium opening 15 of the aquarium 5 containing the rotating drum 4 is also located inside the opening member 8 having the front opening 8a for charging the clothes and facing the front plate opening 14 of the front plate 13. Thus, the space between the water tank opening 15 of the water tank 5 and the front plate opening 14 of the front plate 13 is sealed with an annular cylindrical packing member 16 made of an elastic material such as rubber. Intrusion of water into the main body 1 is prevented.

  Further, the outer periphery of the closed lid body 9 comes into contact with the inner peripheral surface of the lip portion 16a of the packing member 16 so as to seal between them, so that water or steam leaks from the outer periphery of the lid body 9. It ’s not going out.

  Further, as shown in FIG. 3, a flange portion 16b is provided on the front plate 13 side of the packing member 16, and the flange portion 16b fixes the mounting plate 17 to the front plate 13 from the front by screws 21. Accordingly, the concave portion 13 a provided on the front plate 13 and the convex portion 17 a provided on the mounting plate 17 are sandwiched and fixed.

  As shown in FIG. 4, the mounting plate 17 is divided into a plurality of circumferential directions. If the mounting plate 17 is a single ring, if it is deformed, it may not be possible to apply force evenly to the packing member 16 and it may come off. By dividing, it is possible to apply force evenly to the packing member 16 without deviation, and the packing member 16 can be firmly fixed to the front plate 13. Accordingly, it is possible to prevent the packing member from coming off and to prevent water leakage, thereby solving problems such as electric leakage.

  Further, in the case of a single ring, the material of the opening portion is discarded. However, since the material to be discarded can be reduced by dividing in this way, the cost can be reduced.

  In the present embodiment shown in FIG. 4, the mounting plate 17 is divided into four parts, but the number of divisions of the mounting plate 17 is not limited.

  Since the panel member 7 is disposed in front of the front plate 13, a packing member or the like can be attached to the front plate 13, and the attachment plate 17 can be attached from the front surface of the front plate 13 without deteriorating the appearance. This not only does not impair the appearance, but also has an effect of reducing vibration and noise to the panel member 7 due to the fact that the packing member 16 is not directly connected to the panel member 7 serving as an exterior. .

In this embodiment, the packing member 16 is sandwiched between the front plate 13 and the front plate 13 using the mounting plate 17, but it is also conceivable to sandwich the packing member 16 from the back of the exterior as in a conventional drum type washing machine.

  Above the panel member 7, an operation panel 20 on which various switch operation portions 18, a display portion 19 and the like are arranged is attached.

  As described above, according to the drum-type washing machine according to the present invention, the packing member can be firmly fixed to the plate supported by the main body at a low cost, so that the sealing member between the lid and the lip portion of the packing member can be used. Water leakage can be prevented and a safe washing machine can be provided to the home.
