본 발명은 세탁기에 관한 것으로써, 더욱 상세하게는 에어챔버와 챔버캡의 체결력을 향상시켜 에어챔버의 누수를 방지하기 위한 에어챔버와 챔버캡에 관한 것이다.The present invention relates to a washing machine, and more particularly, to an air chamber and a chamber cap for improving the fastening force of the air chamber and the chamber cap to prevent leakage of the air chamber.

이하, 종래 기술에 따른 에어챔버와 챔버캡이 적용된 세탁기에 대하여 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, a washing machine to which an air chamber and a chamber cap according to the prior art will be described with reference to the accompanying drawings.

도 1은 종래 기술에 따른 에어챔버와 챔버캡이 적용된 세탁기의 내부 구조를 개략적으로 나타낸 구성도이고, 도 2는 도 1의 에어챔버와 챔버캡의 분리된 상태를 나타낸 측단면도이다.1 is a schematic view showing the internal structure of a washing machine to which an air chamber and a chamber cap are applied according to the prior art, and FIG. 2 is a side cross-sectional view illustrating a separated state of the air chamber and the chamber cap of FIG. 1.

도 1에 도시된 바와 같이, 종래 기술에 따른 에어챔버(10)와 챔버캡(11)이 적용된 세탁기는 수조(1)의 외주면 일측에는 세탁수의 수위를 감지하도록 수위감지센서(3)와 연결관(4)으로 연결된 에어챔버(10)가 구비되고, 상기 에어챔버(10)의 하측 개구부(10a)에는 챔버캡(11)이 결합된다.As shown in FIG. 1, the washing machine to which the air chamber 10 and the chamber cap 11 according to the prior art are applied is connected to the water level sensor 3 so as to detect the level of the wash water on one side of the outer peripheral surface of the water tank 1. An air chamber 10 connected to the pipe 4 is provided, and the chamber cap 11 is coupled to the lower opening 10a of the air chamber 10.

이 때, 도 2에 도시된 바와 같이, 상기 챔버캡(11)은 에어챔버(10)의 하부측에 형성된 원형의 개구부(10a)를 밀폐시키기 위해, 일측만 개구된 원통형의 몸체부(11a)와, 상기 몸체부(11a)의 개구부 둘레를 따라 원주방향 바깥측으로 절곡된 용착부(11b)로 구성된다. 상기 용착부(11b)는 일방향으로만 돌출 형성됨을 특징으로 한다.At this time, as shown in Figure 2, the chamber cap 11 is a cylindrical body portion 11a of which only one side is opened to seal the circular opening 10a formed at the lower side of the air chamber 10. And a welding portion 11b that is bent circumferentially outward along the circumference of the opening of the body portion 11a. The welding portion 11b is characterized in that the protrusion formed in only one direction.
