함몰부(42)는 제2받침부재(40)의 상면에서 하측으로 일정 깊이로 파인 홈이다. 함몰부(42)는 제1받침부재(30)의 돌출부(33)를 수용하여 밀폐공간부(45)(도 2참조)를 형성하는데, 밀폐공간부(45)는 함몰부(42)의 하면과 돌출부(33)의 하면 사이가 이루는 공간이다. 이와 같은 밀폐공간부(45)는 제1받침부재(30)와 제2받침부재(40)의 상대 운동에 따라서 그 공간이 축소되거나 확대될 수 있다. 따라서 밀폐 공간부(45)와 레그하우징(20) 내부가 서로 연통되도록 마련된 공기유동부(43)는 제1받침부재(30)와 제2받침부재(40)가 상대 운동함에 따라 제1받침부재(30)의 돌출부(33)에 의해서 가려지지 않도록 제2받침부재(40)의 함몰부(42)의 하측에 마련되는 것이 바람직하다. 또한, 공기유동부(43)는 공기가 유동할 수 있는 관 형태로 마련되는데, 공기의 유동 저항을 크게 하기 위해서 그 내경이 최대한 작게 형성되는 것이 바람직하다. 아래에서 도 6과 도 7을 참조하여 더욱 자세히 설명한다.The depression 42 is a groove that is recessed to a predetermined depth from the upper surface of the second supporting member 40 to the lower side. The depression 42 receives the protrusion 33 of the first support member 30 to form a sealed space 45 (see FIG. 2), wherein the sealed space 45 has a lower surface of the recess 42. And the lower surface of the protruding portion 33. Such a sealed space 45 may be reduced or enlarged according to the relative movement of the first support member 30 and the second support member 40. Therefore, the air flow part 43 provided to communicate with the inside of the sealed space 45 and the leg housing 20 has a first support member as the first support member 30 and the second support member 40 move relative to each other. It is preferable that it is provided below the recessed part 42 of the 2nd support member 40 so that it may not be covered by the protrusion part 33 of 30. As shown in FIG. In addition, the air flow portion 43 is provided in the form of a tube through which air can flow, the inner diameter of the air is preferably formed as small as possible to increase the flow resistance of the air. It will be described in more detail with reference to Figures 6 and 7 below.

도 6은 본 발명에 따른 베이스가 상승할 때 세탁기의 높이 조절 장치를 나타낸 동작 상태도이다.Figure 6 is an operating state diagram showing the height adjustment device of the washing machine when the base according to the invention rises.

도 6에 도시된 바와 같이, 베이스(12)가 상승하면 레그하우징(20)도 함께 상승하게 되고, 레그하우징(20)과 결합된 제1받침부재(30)도 함께 상승하게 된다. 이 때 제2받침부재(40)의 함몰부(42)에 수용되어 있던 제1받침부재(30)의 돌출부(33)가 상승하게 되어, 밀폐공간부(45)는 확장된다. 그러나 밀폐공간부(45)가 확장되기 위해서는 공기유동부(43)를 통하여 밀폐공간부(45)로 공기가 유입되어야 하는데, 공기유동부(43)의 내경이 작아서 공기 유동 저항이 발생하여 충분한 유량의 공기가 유입되지 못하므로 제1받침부재(30)의 상승 속도를 늦추게 되어 레그하우징(20)의 상승을 저감시킨다.As shown in FIG. 6, when the base 12 rises, the leg housing 20 also rises, and the first support member 30 coupled with the leg housing 20 also rises together. At this time, the protruding portion 33 of the first supporting member 30 accommodated in the recessed portion 42 of the second supporting member 40 is raised, and the sealed space 45 is expanded. However, in order for the enclosed space portion 45 to expand, air must be introduced into the enclosed space portion 45 through the air flow portion 43. Since the inner diameter of the air flow portion 43 is small, an air flow resistance is generated, thereby sufficient flow rate. Since the air does not flow in, the rising speed of the first support member 30 is slowed to reduce the rise of the leg housing 20.

도 7은 본 발명에 따른 베이스가 하강할 때 세탁기의 높이 조절 장치를 나타낸 동작 상태도이다.7 is an operation state diagram showing the height adjustment device of the washing machine when the base according to the invention is lowered.

도 7에 도시된 바와 같이, 베이스(12)가 하강하면 레그하우징(20)도 함께 하강하게 되고, 코일스프링(11)은 수축하게 된다. 이때 제2받침부재(40)의 함몰 부(42)에 수용되어 있던 제1받침부재(30)의 돌출부(33)가 하강하게 되어, 밀폐공간부(45)는 압축된다. 그러나 밀폐공간부(45)가 압축되기 위해서는 공기유동부(43)를 통하여 밀폐공간부(45)에 있던 공기가 유출되어야 하는데, 공기유동부(43)의 내경이 작아서 공기유동 저항이 발생하여 충분한 유량의 공기가 유출되지 못한다. 이 때 밀폐공간부(45)에 형성된 공기압은 제1받침부재(30)의 하강 속도를 늦추게 되어 레그하우징(20)의 하강을 저감시킨다.As shown in FIG. 7, when the base 12 descends, the leg housing 20 also descends, and the coil spring 11 contracts. At this time, the protruding portion 33 of the first supporting member 30 accommodated in the recessed portion 42 of the second supporting member 40 is lowered, and the sealed space 45 is compressed. However, in order for the airtight space 45 to be compressed, the air in the airtight space 45 must flow out through the air flow 43, and the air flow resistance 43 is sufficient to generate air flow resistance. No air flows out of the flow. At this time, the air pressure formed in the sealed space portion 45 slows down the descending speed of the first support member 30 to reduce the lowering of the leg housing 20.

상기와 같은 구성을 통하여, 세탁기의 작동 시 베이스에 진동이 발생하는 경우 진동을 방지하는 효과가 있다.Through the configuration as described above, when the vibration occurs in the operation of the washing machine there is an effect of preventing the vibration.

또한, 진동을 방지하는 높이 조절 장치를 구현함에 있어서 구조가 간단하고, 부품이 적게 들어서 제조비용이 감소되는 효과가 있다. In addition, in implementing the height adjustment device to prevent vibration, the structure is simple, there are fewer parts, there is an effect that the manufacturing cost is reduced.

또한, 세탁기의 높이 조절 장치를 세탁기에 설치할 때 그 구조가 간단하여 작업 시간이 단축되는 효과가 있다.In addition, when the height adjusting device of the washing machine is installed in the washing machine, its structure is simple, and thus the working time is shortened.
