Description

Door for drum washing machine {DOOR FOR DRUM WASHING MACHINE}

The present invention relates to a door for a drum washing machine, and more particularly, to a drum washing machine which can install a rotating plate rotatably on an inner surface of the door for a drum washing machine to improve washing force and reduce an overload on a motor. It is about.

3 shows a drum washing machine door according to the prior art.

Referring to FIG. 3, a drum washing machine door according to the related art includes a front window 25, an inner window 20, and a frame 30.

The front window 25 is made of tempered glass and is disposed in front of the door, and the inner window 20 is made of tempered glass and is disposed in the drum washing machine.

The frame 30 is fitted with the outer circumferential surfaces of the front window 25 and the inner window 20 so that the front window 25 and the inner window 20 do not leave the door.

Referring to the operation and effects of the drum washing machine door according to the prior art of the configuration as described above are as follows.

Referring back to Figure 3, the drum washing machine door is installed so that the washing machine is sealed to install the front window 25 and the inner window 20 in the center of the door to observe the inside of the washing machine. At this time, a portion of the outer circumferential surface of the front window 25 and the inner window 20 is fitted to the frame 30 and coupled. Meanwhile, the inner window 20 prevents a fluid such as water from flowing out of the drum of the drum washing machine, and the front window 25 prevents a fluid such as water from flowing into the drum of the washing machine from the outside.

However, in the conventional drum washing machine door as described above, when a large amount of laundry is put into the drum and the drum is rotated to operate the drum washing machine, the laundry also rotates in the rotational direction of the drum. At this time, when the laundry is in contact with the inner window of the door of the drum washing machine the laundry in contact with the inner window is not rotated smoothly by the friction is reduced washing power of the laundry and the motor to rotate the drum due to the friction of the laundry The motor is overloaded.

The present invention has been made in order to improve the problems of the prior art as described above, an object of the present invention is to install a rotating plate in the inner window when the drum rotates the laundry near the inner window rotates with the rotating plate to wash the laundry power of the laundry The present invention provides a drum washing machine door which can improve and reduce the overload on the motor by laundry.

Technical problem of the present invention as described above,

In the door for the drum washing machine comprising a front window, an inner window and a frame in which the front window and the inner window is coupled,

A drum washing machine, comprising: a rotating plate coupled to a first through hole formed in a central portion of an inner window disposed on an inner side of a door, and a second through hole formed so as to be rotatably coupled to the rotating part. It is justified by providing a door.

Hereinafter, the door for drum setter according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a partial cross-sectional view of a drum washing machine door according to a preferred embodiment of the present invention, Figure 2 is an enlarged cross-sectional view of the portion "A" of FIG.

1, the drum washing machine door includes a front window 250, an inner window 200, a frame 300, a rotating part 100, and a rotating plate 150.

The front window 250 is made of tempered glass and is disposed in the front part of the door, and the inner window 200 is disposed in the inner part of the door and is made of tempered glass.

A portion of the outer circumferential surface of the front window 250 and the inner window 200 is fitted to the frame 300 by coupling.

The rotating part 100 is fitted into and coupled to the first through hole 201 formed in the inner window 200 and the second through hole 151 formed on the rotating plate 150 disposed on the inner surface of the inner window 200.

Referring to FIG. 2, the first fastening member 120 such as a bolt is fitted into the first through hole 201 formed at the center of the inner window 200, and the rotating member 110 is formed of a bushing. It is fitted to the first fastening member 120.

Rotating plate 150 is a rotating member 110 is inserted into the second through-hole 151 is formed so that the end is coupled, the second fastening member 130 is coupled to the first fastening member 120 rotating member 110 ) Is fastened to the first fastening member 120 so as not to be separated, and the cover 140 is formed in a cylindrical shape to protect the first fastening member 120, the rotating member 110, and the second fastening member 130. It is coupled to the rotating plate 150 to.

The operation and effects of the drum washing machine door according to the preferred embodiment of the present invention configured as described above will be briefly described.

1 and 2, when the rotating plate 150 is installed in the inner window 200, the first fastening member 120 such as a bolt is formed in the first through hole 201 formed in the inner window 200. To the inner direction of the drum from the outside of the drum. At this time, the first fastening member 120 is inserted into the rotating plate 150 in which the rotating member 110 such as a bushing is inserted into the second through hole 151 formed to be short. On the other hand, the second fastening member 130 such as a nut is fastened to the first fastening member 120 of the outer circumferential surface of the rotating plate 150 so that the rotating plate 150 and the rotating member 110 are not separated from the first fastening member 120. do.

In addition, in order to block the first fastening member 120, the rotating member 110, and the second fastening member 130 from contacting the laundry, the cover 140 having a cylindrical shape is coupled to the rotating plate 150.

Next, when the washing machine is operated, when the washing machine operates to rotate the drum, the laundry disposed inside the drum also rotates in the direction in which the drum rotates. At this time, the rotating plate 150 in contact with the laundry is rotated in the direction in which the laundry rotates so that the laundry disposed near the rotating plate 150 rotates inside the drum in the same manner as the laundry disposed near the pulsator. On the other hand, the rotating plate 150 is rotated along with the laundry along the outer circumferential surface of the rotating member 110, such as a bushing (BUSHING) fixed to the first fastening member 120.

As described above, the drum washing machine door according to the prior art, when the washing machine is operated, the laundry contacting the door does not rotate with the drum due to the friction force is reduced the washing force of the laundry disposed near the door and a lot of load on the motor Can be weighted.

Accordingly, the door for a drum washing machine according to the present invention installs a rotating plate to be rotatable on the door, and when the drum rotates to rotate the laundry, the rotating plate contacting the laundry rotates with the laundry to improve the washing force of the laundry disposed near the door. Can reduce the load on the motor.

Although the above has been described with reference to a preferred embodiment of the present invention, the present invention is not limited to these embodiments and can be variously modified and changed within the spirit and scope of the invention shown in the claims below. Those skilled in the art will readily understand.
