Description

Door bracket for drum washing machine {A door braket for drum washing machine}

The present invention relates to a drum washing machine, and more particularly, to a door bracket fixed to a tub so that the door of the drum washing machine is closed to seal the inside of the drum.

In general, the drum washing machine is configured to wash using the falling of the laundry, so that the washing power is superior to the pulsator type.

As shown in FIG. 2, it is supported by a shock absorber (not shown) inside the case 50, and has a tub 52 having an inlet 51 formed therein for injecting laundry, and the inside of the tub 52. A drum (53) rotatably installed at the door, a door (54) rotatably installed at an outer surface of the inlet port (51) of the tub (52), and the door (54) to be in close contact with the inlet port (51). The inlet 51 is composed of a door bracket 55 attached to the inner diameter.

Of course, the water supply / drainage device 56 for supplying / discharging water is installed in the tub 52, and a driving device (not shown in the back of the tub) for rotating the drum 53 is provided. It will be installed.

The installation state of the door bracket 55 is flange-shaped so that the tub 52 is fitted to the inlet opposite side of the door bracket 55 in which the inlet 57 is formed toward the door 54 as shown in FIG. Coupling portion 58 is formed, the drum 53 is located inside the coupling portion 58, the extension portion 59 to shield between the drum 53 and the door bracket 55. ) Is formed.

That is, the position of the tub 52, the door bracket 55 and the drum 53 is disposed so that the drum 53 is rotated in a state where the rotating drum 53 is located on the inner side of the coupling portion 59, and the door bracket ( The gap D spaced a predetermined distance (about 8 mm or more) is formed between 55 and the drum 53 to exclude interference.

The distance between the gaps D is 8 mm or more because, for example, when the drum 53 rotates at 1000 RPM at high speed and a single balance of about 600 g is generated, a drum amplitude of about 7 ° is generated in the direction of the arrow in the drawing. It is set to.

In addition, the extension 59 prevents the laundry from being pushed through the door bracket 55, in particular, the extension 59.

Referring to the operation of the drum washing machine described above, the user opens the door 54 and injects laundry into the tub 52, that is, the drum 53, and then closes the door 54.

After closing the door 54, the user operates the operation panel and the like to drive the drum 53, and washing is performed while the laundry is rotated together with the rotation of the drum 53.

However, in order to avoid interference between the drum and the door bracket as described above, if a gap D is formed between the door bracket and the drum, the laundry is not only rolled up to the above gap when washing, but also sandwiched between the laundry and dehydration. As the laundry rotates at a high speed together with the drum, the laundry is torn or broken.

In addition, the extension formed on the door bracket is worn while the laundry is rotated in the gap, thereby causing the gap to gradually increase, thereby causing the laundry to escape to the tub.

Accordingly, an object of the present invention is to provide a drum washing machine door bracket configured to prevent laundry from being caught between the drum and the door bracket during high-speed rotation such as dehydration of a drum washing machine.

In order to achieve the above object, the present invention is a door washing machine for a drum washing machine which is coupled to the tub at a position where the inlet is formed, spaced apart from the drum and the door is coupled,

It extends from the inner diameter of the door bracket and is characterized in that it comprises a blocking portion formed to be spaced apart by a gap D 'a predetermined distance from the upper end surface of the drum.

1 is a cross-sectional view showing the installation state of the door bracket for the drum washing machine according to the present invention so as to extend from the inner diameter of the door bracket 55 and to be spaced apart by a gap D ', which is a certain distance from the upper end surface of the drum 53. The blocking part 1 is formed, and is formed to extend from the bottom of the blocking part 1 and to be formed at a bottom position so as to be spaced apart from the blocking part 1 by a predetermined distance and not to interfere with the side of the drum 53. The locking part 2 is formed.

Since the blocking part 1 is formed on the upper end of the drum end 53 'which is perpendicular to the amplitude direction during the rotation of the drum 53, even if the gap is formed to about 2 mm, it does not interfere with the drum 53. Will not.

In addition, a groove 3 having a predetermined curvature is formed in the blocking unit 1 at a corresponding position between the blocking unit 1 and the drum 53 to minimize interference with the drum 53.

When the drum 53 is rotated, the main vibration direction is a vertical direction, so that the gap D 'can be formed to a minimum because the amplitude at the position which becomes the horizontal direction is very small.

In addition, the locking portion 2 is formed in a curved surface so as to be close to the bottom position of the drum 53, substantially the end 53 'of the drum between the blocking portion 1 and the locking portion (2) Since it is in this position it will be able to prevent the laundry (W) is discharged to the tub 52 side through this.

Referring to the operation and effect of the present invention as described above, if the laundry (W) is put into the drum 53, the door 54 is closed and the washing or dehydration process is performed, the laundry in the drum 53 As the (W) is rotated, washing or dehydration is performed.

At this time, the laundry (W) is moved to the door 54 side by the rotational force and is also inserted into the gap D 'between the door bracket 55 and the drum 53, the gap D' is Because it is very small, about 2 mm, it does not flow in.

That is, even when the laundry W is to be inserted into the gap D ', the inflow is difficult because the gap is very small.

In particular, since the laundry W moves to the door 54 side (arrow A direction) and the blocking portion is orthogonal, the laundry W can be more efficiently blocked from flowing.

In the washing or dehydrating stroke of the drum 53, even if the drum 53 vibrates in the up and down direction in the drawing, the end portion 53 of the drum 53 is widened because the groove portion 3 widens a gap that is locally separated. ') Can be more minimized to interfere with the blocking unit (1).

Here, a case where relatively thin laundry is introduced between the door bracket 55 and the drum 53 may also occur. Even when the laundry W flows through the blocking part 1, the bottom of the laundry W may be directly at the bottom surface. The laundry W is blocked at the locking portion 2 so that the laundry W is not introduced to the tub 52.

The laundry W passing through the blocking part 1 is pushed into the corner part of the blocking part 1 and the locking part 2 because the centrifugal force acts in the direction indicated by the arrow B in the drawing. Due to the passage through the locking portion 2 is to be introduced to the tub 52 side is blocked.

In particular, in order for the laundry W to flow back between the drum 53 and the catching part 2, the laundry W must be shaped like an “S” shape as indicated by a dotted line in the drawing so that the laundry W and the catching part ( It is very difficult to flow in between 2).

That is, it is very difficult for the laundry W flowing in the B direction to be bent again in an inverted direction and flowed between the locking portion 2 and the drum 53, so that the laundry W moves toward the tub 52. The possibility of inflow is greatly reduced.

As described above, the present invention minimizes the gap D 'between the drum and the door bracket, and is formed to be located on the upper end of the drum, and forms a locking portion located on the bottom of the tub to block the laundry flowing therein. There is an advantage to prevent the laundry from entering.
