It is configured to include a fixed portion 64 is formed, and a fastening position is set and the fastening means 70 is fastened to the fixed portion 64.

상기 저수조(50)의 하부 측면에는 상기 히터 본체(62)의 일측이 관통되는 설치홀(52)이 형성된다.An installation hole 52 through which one side of the heater body 62 penetrates is formed at a lower side surface of the reservoir 50.

상기 저수조(50)의 하부 저면에는 상기 관통된 히터 본체(62)의 일측이 수용되는 수용 홈부(56)가 형성된다.An accommodating groove 56 is formed at a lower bottom surface of the water tank 50 to accommodate one side of the penetrated heater body 62.

상기 히터 본체(62)의 일측에는 세탁수의 누수가 방지되도록 실링부재(58)가 장착된다.One side of the heater body 62 is mounted with a sealing member 58 to prevent leakage of wash water.

상기 히터 본체(62)의 타측에는 상기 히터 본체(62)에 전류가 공급되도록 전원부(미도시)와 연결되는 제 1, 2 단자(66,67)가 형성된다.The other side of the heater body 62 is formed with first and second terminals 66 and 67 connected to a power supply unit (not shown) so that a current is supplied to the heater body 62.

상기 체결수단(70)은 상기 고정부(64) 및 실링부재(58)를 체결하는 체결부(72)와, 상기 체결부(72)에서 돌출되고 상기 실링부재(58)와 고정부(64)에 관통되어 돌출된 단부에서 일정 길이(d)까지 나사산(74)이 형성된 볼트(76)와, 상기 고정부(64)의 타측에서 상기 볼트(76)의 나사산(74)에 체결되는 너트(78)로 구성된다.The fastening means 70 includes a fastening portion 72 for fastening the fixing portion 64 and the sealing member 58, and protrudes from the fastening portion 72 and the sealing member 58 and the fixing portion 64. A bolt 76 having a thread 74 formed to a predetermined length d at an end protruding from it and a nut 78 fastened to the thread 74 of the bolt 76 on the other side of the fixing part 64. It is composed of

상기 나사산(74)의 길이(d)는 상기 볼트(76)와 너트(78)의 체결시, 상기 고정부(64)와 실링부재(58) 및 체결부(72)가 과체결되지 않고 상기 고정부(64)와 실링부재(58) 및 체결부(72)에 변형이 일어나지 않게 너트(78)가 체결되는 최대 거리이다.The length d of the thread 74 is such that the fastening portion 64, the sealing member 58, and the fastening portion 72 are not fastened when the bolt 76 and the nut 78 are fastened. It is the maximum distance that the nut 78 is fastened so that deformation | transformation does not occur in the top part 64, the sealing member 58, and the fastening part 72. FIG.

이하, 상기와 같이 구성된 세탁기의 히터(60) 체결과정을 살펴보면 다음과 같다.Hereinafter, a process of fastening the heater 60 of the washing machine configured as described above will be described.

상기 히터 본체(62)의 일측이 상기 설치홀(52)에 관통되어 상기 수용 홈부(56)에 배치되면, 상기 실링부재(58)와 체결부(72)가 차례로 상기 수용 홈부(56)에서 상기 히터 본체(62)의 일측 단부를 통해 끼워져, 상기 설치홀(52) 방향으로 밀어 넣어진다.When one side of the heater body 62 penetrates through the installation hole 52 and is disposed in the accommodation groove 56, the sealing member 58 and the fastening portion 72 are sequentially in the accommodation groove 56. It is fitted through one end of the heater body 62 and is pushed in the direction of the installation hole 52.

이후, 상기 실링부재(58)는 상기 설치홀(52)에 삽입되고, 상기 체결부(72)에서 돌출된 볼트(76)는 상기 실링부재(58) 및 고정부(64)를 관통하여 나사산(74)이 형성된 부분이 상기 고정부(64)의 타측으로 돌출된다.Thereafter, the sealing member 58 is inserted into the installation hole 52, and the bolt 76 protruding from the fastening portion 72 passes through the sealing member 58 and the fixing portion 64 to be screwed ( A portion formed with 74 protrudes to the other side of the fixing portion 64.

상기 너트(78)는 상기 고정부(64)의 타측에서 상기 볼트(76)의 나사산(74)이 형성된 부분과 체결되고, 상기 고정부(64)와 실링부재(58) 및 체결부(72)는 서로 밀착 고정된다.The nut 78 is fastened to a part where the thread 74 of the bolt 76 is formed at the other side of the fixing part 64, and the fixing part 64, the sealing member 58, and the fastening part 72. Are fixed in close contact with each other.

따라서, 도 4에 도시된 바와 같이, 상기 너트(78)가 일정 위치(d)만큼 형성된 나사산(74)에만 체결 가능하므로 상기 볼트(76)와 너트(78)의 과체결이 일어나지 않고, 설계상의 정위치에 체결되어 상기 고정부(64)와 실링부재(58) 및 체결부(72)의 변형이 생기지 않으므로, 상기 실링부재(58)에 의해 세탁수의 누수가 방지되게 된다.Therefore, as shown in FIG. 4, since the nut 78 can be fastened only to the thread 74 formed by the predetermined position d, the fastening of the bolt 76 and the nut 78 does not occur, Since the fixing part 64 and the sealing member 58 and the fastening portion 72 are not deformed by being fastened in place, leakage of the wash water is prevented by the sealing member 58.

도 5는 본 발명에 따른 제 2 실시예의 히터 일부가 확대 도시된 단면도이다.Figure 5 is an enlarged cross-sectional view of a part of the heater of the second embodiment according to the present invention.

참고로 상기한 제 1 실시예의 구성과 동일 유사한 구성요소에는 동일한 참조번호를 부여하고, 그에 따른 상세한 설명은 생략하기로 한다.For reference, the same reference numerals are given to the same or similar components as those of the first embodiment, and detailed description thereof will be omitted.

상기 체결수단(70)은 상기 실링부재(58)의 타측에 밀착되는 체결부(72)와, 상기 고정부(64)와 실링부재(58) 및 체결부(72)에 관통되게 설치되고 단부에서 일정 위치(d)까지 나사산(74)이 형성된 볼트(76)와, 상기 고정부(64) 또는 체결부(72)의 외측에서 상기 볼트(76)의 나사산(74)에 체결되는 너트(78)로 구성된다.The fastening means 70 is installed to penetrate the fastening portion 72 in close contact with the other side of the sealing member 58, the fixing portion 64, the sealing member 58 and the fastening portion 72 and at the end A bolt 76 having a thread 74 formed to a predetermined position d, and a nut 78 fastened to the thread 74 of the bolt 76 outside the fixing part 64 or the fastening part 72. It consists of.

이하, 설명의 편의를 위해 상기 볼트(76)가 상기 체결부(72)측에서 삽입되어, 상기 체결부(72)와 실링부재(58) 및 고정부(64)에 관통되어 상기 고정부(64)의 외측에서 상기 너트(78)와 체결된 것으로 한정하여 설명한다.Hereinafter, for convenience of description, the bolt 76 is inserted from the fastening part 72 side, and penetrates the fastening part 72, the sealing member 58, and the fixing part 64 to fix the 64. It will be described by limiting the fastening with the nut 78 from the outside.

상기와 같이 구성된 세탁기의 히터(60)는 상기 고정부(64) 또는 체결부(72)에서 상기 볼트(76)가 일체로 제작될 필요가 없으므로, 상기 히터(60)의 제작 공정이 간편하게 된다.Since the heater 60 of the washing machine configured as described above does not need to be integrally manufactured with the bolt 76 at the fixing part 64 or the fastening part 72, the manufacturing process of the heater 60 is simplified.

도 6은 본 발명에 따른 제 3 실시예의 히터 일부가 확대 도시된 단면도이다.6 is an enlarged cross-sectional view of a part of a heater of a third embodiment according to the present invention.

참고로 상기한 제 1 실시예의 구성과 동일 유사한 구성요소에는 동일한 참조번호를 부여하고, 그에 따른 상세한 설명은 생략하기로 한다.For reference, the same reference numerals are given to the same or similar components as those of the first embodiment, and detailed description thereof will be omitted.

본 제 2 실시예에 따른 세탁기의 히터(60)는 히터 본체(62)와, 고정부(64)와, 체결수단(70)을 포함하여 구성된다.The heater 60 of the washing machine according to the second embodiment includes a heater body 62, a fixing part 64, and a fastening means 70.

상기 체결수단(70)은 상기 실링부재(58)의 타측에 밀착되는 체결부(72)와, 상기 고정부(64)에서 돌출되어 상기 실링부재(58)와 체결부(72)에 관통되고 돌출된 단부에서 일정 위치(d)까지 나사산(74)이 형성된 볼트(76)와, 상기 체결부(72)의 외측에서 상기 볼트(76)의 나사산(74)에 체결되는 너트(78)로 구성된다.The fastening means 70 is a fastening portion 72 in close contact with the other side of the sealing member 58, and protrudes from the fixing portion 64 to penetrate and protrude through the sealing member 58 and the fastening portion 72 And a nut 76 fastened to the threaded portion 74 of the bolt 76 from the outside of the fastening portion 72 and the bolt 76 with the threaded 74 formed from the end portion thereof to a predetermined position d. .

상기와 같이 구성되는 본 발명에 따른 세탁기의 히터는 체결부에 너트가 체결되는 최대 위치에 나사산이 형성된 볼트가 돌출되어, 실링부재 밀착시 고정부와 실링부재 및 체결부의 과체결이 방지되고 변형이 발생되지 않는 이점이 있다.Heater of the washing machine according to the present invention is configured as described above is a bolt is formed in the screw thread is projected to the maximum position of the fastening nut, preventing the fastening of the fixing part and the sealing member and the fastening portion when the sealing member is in close contact with the deformation There is an advantage that does not occur.

또한, 히터의 고정부 또는 체결부에 볼트가 일체로 돌출되지 않고 따로 고정부와 실링부재 및 체결부에 관통되는 볼트가 형성되어, 히터의 제작 공정이 간편해 지는 이점이 있다.In addition, since the bolts do not integrally protrude from the fixing part or the fastening part of the heater, the bolts penetrating the fixing part, the sealing member, and the fastening part are formed separately, thereby simplifying the manufacturing process of the heater.
