Description

세탁기용 진동방지 렉{A vibrationless leg for washing machine}A vibrationless leg for washing machine

본 발명은 세탁기에 관한 것으로, 상세하게는 세탁기의 하부에 결합되어 세탁이나 탈수과정에서 진동을 감소시키는 렉의 강도 및 탄성력을 세탁물과 함께 세탁기에 투입된 세탁수의 중량에 따라 가변시킴으로써 진동을 효과적으로 감소시킬수 있도록 구성한 세탁기용 진동방지 렉에 관한 것이다.The present invention relates to a washing machine, and more particularly, the vibration is effectively reduced by varying the strength and elastic force of the rack coupled to the lower part of the washing machine to reduce vibration during washing or dehydration process according to the weight of the washing water put into the washing machine together with the laundry. It relates to a vibration preventing rack for a washing machine configured to be.

일반적으로 통상적인 구조를 갖는 가정용 세탁기는 내부에 고중량의 세탁물이 투입되는 한편, 세탁이나 탈수과정에서 세탁조를 고속으로 회전시킴에 따라 진동이 발생한다.In general, while a washing machine having a conventional structure is loaded with a heavy laundry inside, vibration occurs as the washing tank is rotated at a high speed during washing or dehydration.

이와 같은 진동은 소음을 동반하는 한편, 세탁기의 수명을 단축시키게 되므로 세탁기의 하부에는 고무재로 이루어진 진동방지부재를 부착시켜 진동을 감소시키고, 바닥면간의 직접 접촉에 따른 세탁기의 손상을 방지하며, 세탁기로부터 돌출되는 진동방지부재의 높낮이를 적절히 조절함으로써 세탁기가 수평상태로 설치되도록 한다.Such vibrations are accompanied by noise, and shorten the life of the washing machine, thereby reducing vibration by attaching a vibration preventing member made of a rubber material to the lower part of the washing machine, and preventing damage to the washing machine due to direct contact between floors. By properly adjusting the height of the vibration preventing member protruding from the washing machine, the washing machine is installed in a horizontal state.

도 1은 통상적인 구조를 갖는 세탁기(200)의 저면 사시도로서, 이와 같은 세탁기(200)의 각 모서리 내측에는 체결정도에 따라 세탁기(200)의 하부로부터 돌출된 길이가 가감되는 나사봉(5)의 선단에 원형의 고무판(1)을 부착시킨 높이조절 렉(10)이 각각 결합된다.1 is a bottom perspective view of a washing machine 200 having a conventional structure, each of the corners of the washing machine 200 is a screw rod (5) protruding from the bottom of the washing machine 200 according to the degree of fastening is added or subtracted The height adjustment rack 10 is attached to each end of the circular rubber plate (1) is coupled to.

이와 같은 종래의 높이조절 렉(10)은, 초기 설치과정에서 세탁기(200) 하부의 각 모서리 내측으로부터 돌출된 정도를 조절함으로써 세탁기(200)가 바닥면으로부터 정확한 수평을 유지할 수 있도록 하며, 세탁이나 탈수과정에서 발생한 진동은 상기한 고무판(1)의 탄성에 의해 흡수되도록 한다.Such a conventional height adjustment rack 10, by adjusting the degree of protruding from the inside of each corner of the lower part of the washing machine 200 in the initial installation process, so that the washing machine 200 can maintain a precise level from the bottom surface, washing or The vibration generated in the dehydration process is to be absorbed by the elasticity of the rubber plate (1).

한편, 높이조절 렉(10)의 진동 흡수율은 상기한 높이조절 렉(10)을 구성하는 고무판(1)의 탄성에 따라 각기 다른 값을 갖게 되는데, 예로써 세탁기(20)에 고중량의 세탁물이 저장될 경우에는 높은 강도를 갖는 한편, 낮은 탄성계수를 갖는 고무판이 효과적으로 진동을 흡수하며, 이와 반대로 세탁기(200)에 소량의 세탁물이 투입될 경우에는 낮은 강도와 높은 탄성계수를 갖는 고무판이 보다 효과적으로 진동을 흡수한다.On the other hand, the vibration absorption rate of the height adjustment rack 10 has a different value depending on the elasticity of the rubber plate (1) constituting the height adjustment rack 10, for example, a heavy laundry is stored in the washing machine (20) If the rubber plate having a high strength while having a low modulus of elasticity effectively absorbs vibration, on the contrary, when a small amount of laundry is put into the washing machine 200, the rubber plate having a low strength and high modulus of elasticity vibrates more effectively. Absorb it.

따라서, 세탁기(200)의 진동을 효과적으로 감소시키고자 할 경우에는 중량에 따라 강도와 탄성력의 적절한 조절이 요구되는데, 상기한 바와 같은 종래의 세탁기용 높이조절 렉(10)은 세탁물의 중량에 따른 강도 및 탄성의 조절이 불가능한 구조로 이루어지므로 진동이 효율적으로 이루어지지 못하는 등의 문제가 발생한다.Therefore, in order to effectively reduce the vibration of the washing machine 200 is required to appropriately adjust the strength and elastic force according to the weight, the conventional height-adjusting rack 10 for the washing machine as described above the strength according to the weight of the laundry And because it is made of a structure that is unable to adjust the elasticity, problems such as the vibration is not made efficiently.

상기한 바와 같은 과정에 따라 세탁기와의 결합이 이루어지는 본 발명은, 세탁기 하부의 각 모서리 내측에 각각 결합됨으로써 하나의 세탁기에 대해 4개의 부위에 각각 설치되어 세탁기의 하부를 지지한다.According to the present invention in which the coupling with the washing machine is performed according to the above-described process, each of the four coupling parts is installed at each of four parts of the washing machine to support the lower part of the washing machine.

상기한 구성을 갖는 본 발명의 작용 및 효과를 이하에서 설명한다.The operation and effects of the present invention having the above-described configuration will be described below.

본 발명에 의한 세탁기용 진동방지 렉(50)은, 세탁기에 투입된 세탁물 및 세탁수의 중량에 따라 방진부재(30)의 관통공(21)에 삽입된 승강부재(20)가동기모터(10)의 정역회전에 따라 삽입정도를 가감함으로써 방진부재(30)의 강도와 탄성력을 조절한다.Vibration preventing rack 50 for a washing machine according to the present invention, the lifting member 20 is inserted into the through-hole 21 of the dustproof member 30 according to the weight of the laundry and washing water put into the washing machine movable motor 10 By adjusting the insertion degree according to the forward and reverse rotation of the dustproof member 30 to adjust the strength and elastic force.

상기한 바와 같은 본 발명은 세탁과정에서 세탁기에 투입된 세탁물 및 세탁수의 중량에 따라 방진부재(30)로부터 승강부재(20)를 적절히 승강시켜 방진부재(30)의 강도 및 탄성력을 가변시킨다.As described above, the present invention changes the strength and elastic force of the dustproof member 30 by appropriately lifting the elevating member 20 from the dustproof member 30 according to the weight of laundry and washing water put into the washing machine in the washing process.

이와 같은 본 발명은 예로써 세탁기의 내부에 다량의 세탁물 및 세탁수가 투입됨에 따라 세탁기가 고중량을 가질 경우에는 제어부로부터 전원이 인가된 과정에서 도 4a와 같이 동기모터(10)을 정회전시킨다.As such, the present invention rotates the synchronous motor 10 forward as shown in FIG. 4A in the process of applying power from the control unit when the washing machine has a high weight as a large amount of laundry and washing water are put into the washing machine.

상기한 바와 같이 동기모터(10)가 정회전하면, 상기한 동기모터(10)의 회전력이 회전축(1)을 통해 승강부재(20)로 전달된다.As described above, when the synchronous motor 10 rotates forward, the rotational force of the synchronous motor 10 is transmitted to the lifting member 20 through the rotation shaft 1.

이때 승강부재(20)는 양측의 가이드 돌기(13,14)과 하우징(40)의 가이드 홈(33,34)에 각각 삽입되어 회전이 방지되므로 동기모터(10)의 회전력은 직선운동으로 변환되어 승강부재(20)를 방진부재(30)의 관통공(21) 내측으로 삽입되며, 이에 따라 방진부재(30)의 강도를 높이는 한편, 탄성력을 저하시킨다.At this time, the elevating member 20 is inserted into the guide protrusions 13 and 14 of both sides and the guide grooves 33 and 34 of the housing 40, respectively, so that rotation is prevented, so that the rotational force of the synchronous motor 10 is converted into linear motion. The lifting member 20 is inserted into the through hole 21 of the dustproof member 30, thereby increasing the strength of the dustproof member 30 and lowering the elastic force.

또한 이와 반대로 세탁기의 내부에 소량의 세탁물 및 세탁수가 투입되어 세탁기가 경량일 경우에는 도 4b와 같이 제어부로부터 동기모터(10)가 전술한 방향의 역방향으로 회전하도록 전원을 공급함으로써 동기모터(10)를 역회전시킨다.On the contrary, when a small amount of laundry and washing water are put into the washing machine and the washing machine is lightweight, the synchronous motor 10 is supplied from the control unit so that the synchronous motor 10 rotates in the opposite direction in the above-mentioned direction as shown in FIG. 4B. Rotate

상기한 바와 같이 동기모터(10)가 역회전하면, 상기한 동기모터(10)의 회전력이 직선운동으로 변환되어 방진부재(30)로부터 승강부재(20)가 이탈하는 한편, 방진부재(30)의 강도를 저하시키고, 탄성력을 높여 진동이 원활히 흡수되도록 한다.As described above, when the synchronous motor 10 rotates in reverse, the rotational force of the synchronous motor 10 is converted into a linear motion so that the lifting member 20 is separated from the dustproof member 30 and the dustproof member 30. Lower the strength of the elastic force to increase the vibration to be smoothly absorbed.

한편, 동기모터(10)의 회전에 의한 방진부재(30)와 승강부재(20)간의 결합정도는 반복된 실험을 통해 얻어진 결과치를 제어부에 입력시킴으로써 세탁기의 무게에 비례하게 방진부재(30)의 적절한 강도 및 탄성량이 조절되도록 한다.On the other hand, the degree of coupling between the anti-vibration member 30 and the elevating member 20 by the rotation of the synchronous motor 10 is input to the control unit the result value obtained through repeated experiments of the anti-vibration member 30 in proportion to the weight of the washing machine Allow the amount of strength and elasticity to be adjusted.

이상에서 설명한 바와 같이 본 발명에 의한 세탁기용 진동방지 렉(50)은, 세탁기에 투입된 세탁물 및 세탁수의 중량에 따라 방진부재(30)의 내측에 결합되는 승강부재(20)의 삽입정도가 조절되며, 이에 따라서 세탁물 및 세탁수의 중량에 따라 진동을 감소시키는 방진부재(30)의 강도 및 탄성력이 가변된다.As described above, the anti-vibration rack 50 for a washing machine according to the present invention adjusts the degree of insertion of the elevating member 20 coupled to the inside of the dustproof member 30 according to the weight of laundry and washing water put into the washing machine. Accordingly, the strength and elastic force of the anti-vibration member 30 for reducing vibration in accordance with the weight of the laundry and wash water is variable.

따라서 본 발명에 의한 세탁기용 진동방지 렉(50)은, 세탁물 및 세탁수의 중량에 따른 진동을 효과적으로 흡수함으로써 세탁과정에서 진동 및 소음의 발생을 차단하고, 불필요한 진동에 따른 부품의 고장등을 방지할 수 있다.Therefore, the anti-vibration rack 50 for a washing machine according to the present invention effectively absorbs vibrations according to the weight of laundry and washing water, thereby preventing the occurrence of vibration and noise in the washing process and preventing breakdown of components due to unnecessary vibrations. can do.
