지지부(30)가 회전축(16)과 평행하게 설치되므로, 원통 형상으로 형성된 드럼(20)의 내측면과 지지부(30)가 접하는 면적이 증대되어 지지부(30)의 설치가 안정적으로 이루어진다.Since the support part 30 is installed in parallel with the rotation shaft 16, the area where the inner surface of the drum 20 formed in the cylindrical shape and the support part 30 are increased to make the support part 30 stable.

일 실시예에 따른 지지부(30)는 120도 간격을 이루며 드럼(20)의 내측에 복수로 설치된다. 지지부(30)가 서로 이루는 간격은 120도에 한정하는 것은 아니며, 드럼(20)의 크기 및 형상 등을 고려하여 지지부(30) 사이의 각도 및 지지부(30)의 개수는 변경될 수 있다.The support part 30 according to an embodiment is provided in plurality in the drum 20 at intervals of 120 degrees. The interval between the support parts 30 is not limited to 120 degrees, and the angle between the support parts 30 and the number of the support parts 30 may be changed in consideration of the size and shape of the drum 20.

이러한 지지부(30)는, 드럼(20)의 내측면에 접하여 설치되는 베이스부재(32) 및 베이스부재(32)의 양측에서 돌출되어 회전부(40)를 지지하는 장착부재(34)를 포함한다.The support part 30 includes a base member 32 installed in contact with the inner surface of the drum 20 and a mounting member 34 protruding from both sides of the base member 32 to support the rotating part 40.

판재 형상으로 형성된 베이스부재(32)는 드럼(20)의 내측면에 용접 작업으로 고정될 수 있으며, 용접이 아닌 볼트나 나사를 사용하는 체결부재에 의해 드럼(20)의 내측면에 고정될 수 있는 등 다양한 변형 실시가 가능하다.Base member 32 formed in a plate shape can be fixed to the inner surface of the drum 20 by a welding operation, it can be fixed to the inner surface of the drum 20 by a fastening member using a bolt or screw rather than welding. Various modifications are possible, such as that.

한편, 회전부(40)는 지지부(30)에 회전 가능하게 설치되는 기술사상 안에서 원기둥 형상을 포함한 다양한 형상으로 변형될 수 있다.On the other hand, the rotating part 40 may be deformed into various shapes including a cylindrical shape in the technical concept that is rotatably installed on the support 30.

일 실시예에 따른 회전부(40)는, 세탁돌기부(50)가 외측에 형성되는 회전몸체(42) 및 회전몸체(42)의 양측으로 돌출되어 지지부(30)에 회전 가능하게 연결되는 축돌기(44)를 포함한다.Rotating portion 40 according to an embodiment, the washing projection 50 is a rotating protrusion 42 which is formed on the outer side and the projection protruding to both sides of the rotating body 42 rotatably connected to the support (30) ( 44).

회전몸체(42)는 원기둥 형상으로 형성되며, 이러한 회전몸체(42)의 양측으로 축돌기(44)가 돌출되어 장착부재(34)에 회전 가능하게 설치된다.Rotating body 42 is formed in a cylindrical shape, the axial projections 44 protrude to both sides of the rotating body 42 is rotatably installed on the mounting member (34).

도 3과 도 4에 도시된 바와 같이, 회전부(40)의 외측으로 돌출되어 드럼(20)의 내측에 있는 세탁물과 접촉되는 세탁돌기부(50)는, 세탁물의 세탁효율을 향상시키는 기술사상 안에서 다양한 형상으로 변형될 수 있다.As shown in FIG. 3 and FIG. 4, the laundry protrusion part 50 protruding outward from the rotating part 40 to be in contact with the laundry inside the drum 20 may be used within the technical concept of improving the washing efficiency of the laundry. It may be deformed into a shape.

일 실시예에 따른 세탁돌기부(50)는, 회전몸체(42)의 외주면을 따라 복수 개로 돌출되는 접촉돌기(52) 및 접촉돌기(52)의 양측에 곡선 형상으로 홈을 형성하는 라운드부(54)를 포함한다.Washing protrusions 50 according to an embodiment, the round protrusions 54 to form a groove in a curved shape on both sides of the contact protrusions 52 and the contact protrusions 52 protruding in a plurality along the outer circumferential surface of the rotary body 42. ).

원기둥 형상으로 형성된 회전몸체(42)의 외주면을 따라 복수의 접촉돌기(52)가 형성된다. 접촉돌기(52)는 모서리를 구비하는 뾰쪽한 형상으로 형성될 수 있으며, 세탁물의 손상을 감소시키기 위해 접촉돌기(52)의 끝 부분은 라운드처리를 할 수 있다.A plurality of contact protrusions 52 are formed along the outer circumferential surface of the rotating body 42 formed in a cylindrical shape. The contact protrusion 52 may be formed in a pointed shape having an edge, and the end portion of the contact protrusion 52 may be rounded to reduce the damage of the laundry.

접촉돌기(52)와 이웃한 접촉돌기(52)의 사이에는 곡선 형상으로 홈을 형성하는 라운드부(54)가 구비되므로, 세탁용 세제 등이 접촉돌기(52)와 이웃한 접촉돌기(52)의 사이에 끼이는 현상이 방지된다.Since the rounded portion 54 is formed between the contacting protrusions 52 and the adjacent contacting protrusions 52 to form a groove in a curved shape, laundry detergent or the like is disposed between the contacting protrusions 52 and the adjacent contacting protrusions 52. The phenomenon of pinching in between is prevented.

이하에서는 첨부된 도면들을 참조하여 본 발명의 일 실시예에 따른 드럼세탁기(1)의 작동상태를 상세히 설명한다.Hereinafter, an operation state of the drum washing machine 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

드럼(20)의 내측에 세탁물을 투입한 후, 도어(12)를 닫아서 드럼(20)의 전방을 패쇄한다.After the laundry is put into the drum 20, the front of the drum 20 is closed by closing the door 12.

드럼세탁기(1)가 동작되면, 모터(18)의 동력은 회전축(16)을 통해 드럼(20)으로 전달된다.When the drum washing machine 1 is operated, the power of the motor 18 is transmitted to the drum 20 through the rotating shaft 16.

드럼(20)이 회전되면, 드럼(20)의 내측으로 돌출된 세탁돌기부(50)가 세탁물을 들어올리는 동시에, 세탁물에 접하여 세탁돌기부(50)가 회전되면서 세탁물과 세탁돌기부(50)의 사이에 마찰이 발생된다.When the drum 20 is rotated, the laundry protrusion part 50 protruding into the drum 20 lifts the laundry, and the laundry protrusion part 50 is rotated in contact with the laundry while the laundry protrusion part 50 rotates between the laundry and the laundry protrusion part 50. Friction is generated.

장착부재(34)의 사이에 설치된 회전부(40)가 회전되면, 회전부(40)와 함께 세탁돌기부(50)가 회전되면서 세탁돌기부(50)와 세탁물의 사이에 마찰이 발생한다.When the rotating part 40 installed between the mounting members 34 is rotated, the washing protrusion 50 is rotated together with the rotating part 40 to generate friction between the washing protrusion 50 and the laundry.

세탁물을 드럼(20)의 회전에 의한 낙차로 발생된 마찰 및 세탁돌기부(50)에 접하여 발생하는 마찰로 세탁이 이루어지므로, 드럼세탁기(1)의 세탁성능이 향상된다.Since the laundry is washed by friction generated by the free fall due to the rotation of the drum 20 and the friction generated by contacting the washing protrusion 50, the washing performance of the drum washing machine 1 is improved.

상술한 바와 같은 구성에 의하면, 일 실시예에 따른 드럼세탁기(1)는, 드럼(20)의 내측에 회전 가능하게 설치된 세탁돌기부(50)가 드럼(20)과 함께 이동하면서 세탁물을 들어올리는 한편, 세탁돌기부(50)가 세탁물에 접하여 회전하면서 빨래판 역할을 하므로, 세탁물의 세탁성능을 향상시킬 수 있다.According to the above-described configuration, the drum washing machine 1 according to the embodiment lifts the laundry while the laundry protrusion part 50 rotatably installed inside the drum 20 moves along with the drum 20. The washing protrusion 50 rotates in contact with the laundry and thus serves as a washboard, thereby improving washing performance of the laundry.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

또한, 가정용으로 사용되는 드럼세탁기를 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 산업용을 포함한 다양한 종류의 세탁기에도 본 발명에 의한 드럼세탁기가 사용될 수 있다.Also, although the drum washing machine used for home use has been described as an example, the present invention is merely an example, and a drum washing machine according to the present invention can be used for various types of washing machines including industrial use.

따라서, 본 발명의 진정한 기술적 보호범위는 특허청구범위에 의해서 정하여져야 할 것이다.
Accordingly, the true scope of protection of the present invention should be defined by the claims.
