Description

Drum Washing Machine {DRUM WASHING MACHINE}

The present invention relates to a drum washing machine, and more particularly, to a drum washing machine in which a small laundry such as stockings is stored in a separate space from the general laundry so that the laundry can be simultaneously washed with the general laundry.

The washing machine is mainly driven by the electric motor, and the washing, rinsing, and dehydration processes are carried out to remove the dirt on the clothes by using the action of detergent and water. Its components consist of a motor, a power unit, a mechanical unit that delivers energy to the laundry, a control unit that regulates the washing process, and a water supply and drainage system that puts water in and out.

According to the washing method, the washing machine is classified into an agitator type, a pulsator type, and a drum type.

Stirring type is a method of washing by rotating the wing-shaped stirrer to the left and right in the center of the washing tank, Wakwon type is a method of washing with water generated by rotating the disk-shaped pulsator, drum type is formed with several protrusions Put the laundry, water and detergent inside the drum, and rotate it at low speed on the horizontal axis to wash the laundry by the impact of falling and falling.

Drum type has little advantage of laundry damage and has the advantage of using less water, and in recent years, its use is increasing.

The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

In the related art, when a laundry having a small volume, such as stockings or baby socks, is to be washed, there is a problem in that energy consumption is excessively generated since the laundry cannot be washed separately from general laundry. In addition, since the laundry having a small volume is often caught in the gap between the drum and the tub, there is a problem of causing a failure of the drum washing machine.

Therefore, there is a need for improvement.

The present invention has been made to improve the above problems, an object of the present invention is to provide a drum washing machine in which a small laundry, such as stockings, is stored in a separate space from the general laundry so that the laundry can be simultaneously washed with the general laundry.

According to the drum washing machine of the present invention: a cabinet forming an appearance; A tub provided inside the cabinet and configured to wash water; A drum provided inside the tub and containing laundry; And a lifter installed on the drum to lift laundry stored in the drum by the rotation of the drum, wherein the lifter is rotatably formed with a first lifter portion forming an external shape of one side and the first lifter portion. And a second lifter portion coupled to and forming an external shape of the other side.

Preferably, the first and second lifter portions are hinged to each other.

Preferably, one end of the second lifter portion is provided with a hook, and the inner surface of the drum is provided with a hook groove for seating the hook.

Preferably, the first and second lifter holes are provided on the side surfaces of the first and second lifter portions.

According to the drum washing machine according to the present invention, since the laundry having a small volume such as stockings is stored in a separate space from the general laundry, washing can be prevented from damaging the small laundry.

In addition, according to the drum washing machine according to the present invention, since a small volume of laundry can be washed at the same time as general laundry in a single washing stroke, energy consumption can be reduced.

Hereinafter, a drum washing machine according to an embodiment of the present invention will be described with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

The front plate of the cabinet 10 is provided with a laundry access hole (not shown) through which laundry is entered and provided with a door 11 for selectively opening and closing the laundry entrance hole.

Tub 20 is made of a hollow cylindrical shape lying sideways, the opening hole (not shown) is formed behind the laundry access hole.

The upper portion of the tub 20 is provided with a water supply device 21 for supplying the wash water into the tub 20 and a detergent housing 22 for supplying detergent. The drum 30 is disposed in the tub 20 so as to be rotatable.

Like the tub 20, the drum 30 has a hollow cylindrical shape lying on its side, and an opening hole (not shown) is formed at the rear of the laundry access hole. In addition, a through hole (not shown) is formed at a side surface of the drum 30 to allow the fresh water washed in the tub 20 to enter and exit, and a lifter 100 is mounted on the inner circumferential surface thereof.

The motor 40 is a device for generating a driving force, and transmits the driving force generated by the shaft 40a connected to the rear side of the drum 30 through the tub 20 to the drum 30.

The spring 50 absorbs the vibration of the tub 20 generated during the washing stroke. One side of the spring 50 is coupled to the upper portion of the tub 20, the other side is coupled to the top plate of the cabinet 10. One spring 50 is provided at each of the front and rear portions of the tub 20 to absorb vibration generated by the left and right up and down flow of the tub 20.

Damper 60 attenuates the vibration of the tub 20 generated during the washing stroke with the spring 50, one side of the damper 60 is coupled to the lower portion of the tub 20, the other side of the cabinet 10 It is combined with the lower plate.

The lifter 100 is formed to face the central portion of the drum 30 on the inner circumferential surface of the drum 30. The lifter 100 lifts laundry stored in the drum 30 by the rotation of the drum 30.

The lifter 100 includes a first lifter unit 110 and a second lifter unit 120. The first lifter unit 110 forms one side of the lifter 100, and the second lifter unit 120 forms the other side of the lifter 100. That is, the outer shape of the lifter 100 is formed by the first lifter 110 and the second lifter 120. As a result, the laundry having a small volume such as stockings stored in the lifter 100 is washed in a space separate from the general laundry.

One end of the first lifter 110 is coupled to the inner circumferential surface of the drum 30, and the other end is hinged to the second lifter 120. The first lifter hole 112 is formed on the side of the first lifter 110 so that washing water and detergent are introduced into the lifter 100.

The other end of the first lifter 110 is provided with a first hinge 111. The first hinge 111 is formed in a circular shape or a circular shape of which one side is opened to surround the hinge shaft 130.
