직결식 세탁기의 구동축용 베어링의 충격흡수장치Shock-absorbing device for the drive shaft bearing of direct type washing machine

본발명은 직결식 세탁기에 관한 것으로 특히, 세탁공정과 탈수공정을 수행하기 위하여 회전되는 세탁내조 및 구동축의 부상력에 의해 상측으로 부상되는 하측베어링의 내륜과 함께 외륜도 부상되도록 한 뒤 상기의 부상되는 외륜에 보압탄성부재의 탄성을 부여토록 하여 베어링의 충격을 흡수시킬 수 있도록 하는 동시에 소음의 발생을 억제시킬 수 있도록된 직결식 세탁기의 구동축용 베어링의 충격흡수장치에 관한 것이다.The present invention relates to a direct type washing machine, and in particular, the outer ring is injured together with the inner ring of the lower bearing, which is injured upward by the washing force and the driving shaft which are rotated to perform the washing process and the dehydration process. The present invention relates to a shock absorbing device for a drive shaft bearing of a direct type washing machine, which is configured to impart elasticity of a pressure-elastic member to an outer ring, thereby absorbing the impact of the bearing and suppressing the generation of noise.

종래 직결식 세탁기(1)의 구성은 도1에 나타내었다.The configuration of a conventional direct type washing machine 1 is shown in FIG.

즉, 상기의 결합구성은 세탁물을 세탁수와 혼합하여 세탁공정과 탈수공정을 수행 하는 세탁날개(3)가 형성된 세탁내조(2)와,That is, the combined configuration of the laundry inner tub (2) and the laundry wing (3) formed by mixing the laundry with the wash water to perform the washing process and dehydration process, and

상기 세탁내조(2)를 회전시키기 위하여 세탁내조(2)와 연결된 구동축(4)과,A drive shaft 4 connected with the washing tub 2 to rotate the washing tub 2,

상기 구동축(4)을 안정된 상태로 지지시키기 위하여 구동축(4)의 상,하측부로 결합되는 상,하측베어링(8)(9)과,Upper and lower bearings (8) (9) coupled to the upper and lower portions of the drive shaft (4) to support the drive shaft (4) in a stable state,

상기 상,하측베어링(8)(9)을 지지하기 위하여 상,하측베어링(8)(9)을 상,하측 압입홈(6)(7)으로 압입시키고 있는 세탁외조에 결합된 베어링하우징(5)과,Bearing housing (5) coupled to the laundry outer tub that presses the upper and lower bearings (8) and (9) into the upper and lower press-in grooves (6) and (7) to support the upper and lower bearings (8) and (9). )and,

상기 베어링하우징(5)의 하측부에 고정되어 전기력을 발생시키는 모우터(11)의 스테이터(12)와,A stator 12 of the motor 11 fixed to the lower side of the bearing housing 5 to generate an electric force;

상기 스테이터(12)의 전기력에 의해 회전되면서 구동축(4)을 회전시키는 구동축(4)에 결합된 모우터(11)의 로터(13)를 구비한 구성이다.The rotor 13 of the motor 11 coupled to the drive shaft 4 for rotating the drive shaft 4 while being rotated by the electric force of the stator 12 is configured.

상기와 같은 구성에 따른 작용효과를 설명하면 다음과 같다.Referring to the effects of the configuration as described above are as follows.

먼저, 세탁물을 직결식 세탁기(1)의 세탁내조(2)에 투입을 시킨 뒤 작동보턴을 누르면 급수가 이루어지게 된다.First, the laundry is put into the washing tank 2 of the direct-type washing machine 1, and then press the operating button, the water is made.

그리고, 상기의 세탁내조(2)내부로 급수가 완료되면 모우터(11)가 작동하게 된다.When the water supply is completed inside the washing tank 2, the motor 11 is operated.

즉, 상기 모우터(11)의 스테이터(12)가 베어링하우징(5)에 결합된 상태에서 전기력을 발생시키기 때문에 로터(13)가 회전을 하게 된다.That is, the rotor 13 rotates because the stator 12 of the motor 11 generates electric force in a state in which it is coupled to the bearing housing 5.

또한, 상기 로터(13)의 회전에 의해 로터(13)에 결합된 구동축(4)이 베어링하우징(5)에 결합된 상,하측베어링(8)(9)에 의해 원활한 회전을 하게 된다.In addition, the drive shaft 4 coupled to the rotor 13 by the rotation of the rotor 13 is smoothly rotated by the upper and lower bearings 8 and 9 coupled to the bearing housing 5.

따라서, 상기 구동축(4)의 회전에 의해 구동축(4)과 연결된 세탁내조(2)가 회전되면서 세탁날개(3)에 의해 세탁물을 세탁할 수 있게 된다.Accordingly, the laundry inner tub 2 connected to the drive shaft 4 is rotated by the rotation of the drive shaft 4, so that the laundry can be washed by the washing blade 3.

그러나, 상기의 구동축(4)과 세탁내조(2)의 회전이 이루어지면 구동축(4)이 원심력에 의해 상측으로 상승하게 되는 부상력이 발생하게 된다.However, when the driving shaft 4 and the washing inner tub 2 are rotated, a floating force is generated in which the driving shaft 4 rises upward by the centrifugal force.

즉, 상기 구동축(4)의 부상력에 의해 하측베어링(9)의 내륜(9a)이 상승되는 반면 외륜(9b)은 하측베어링압지홈(7)에 걸려있는 상태가 되므로 부상하지 않게 된다.That is, the inner ring 9a of the lower bearing 9 is lifted by the floating force of the drive shaft 4, while the outer ring 9b is caught in the lower bearing pressure groove 7 so as not to be injured.

그리고, 상기 상측으로 부상되는 하측베어링(9)의 내륜(9a)과 원위치를 유지하고 있는 외륜(9b)에 의해 이들 중간의 보올(9c)은 전단력을 받게 되므로 상당한 힘이 작용되어진다.Then, the middle bowl 9c is subjected to a shearing force by the inner ring 9a of the lower bearing 9 which floats upward and the outer ring 9b holding its original position, so that a considerable force is applied.

따라서, 상기 하측베어링(9)에 작용되는 힘에 의해 베어링의 수명이 줄어들게 되는 동시에 내륜(9a)과 외륜(9b)이 보올(9c)을 상,하측에서 누르는 힘에 의해 발생되는 마찰력으로 심한 소음이 발생되는 문제점을 가지고 있었다.Therefore, the life of the bearing is reduced by the force acting on the lower bearing 9, and at the same time, the inner ring 9a and the outer ring 9b are severely noised by the friction force generated by the force pressing the bowl 9c from the upper and lower sides. This had a problem that occurred.

이러한 종래의 문제점 등을 해결 보완하기 위한 본발명의 목적은,The purpose of the present invention for solving and complementing such a conventional problem,

직결식 세탁기의 구동축이 회전되면서 부상시 하측베어링으로 작용되는 충격을 흡수하는 동시에 상기 베어링에서 발생되는 소음 등을 막을 수 있도록 하는 목적을 제공한다.As the drive shaft of the direct-type washing machine rotates, it provides an object to prevent the noise generated from the bearing while absorbing the shock acting as the lower bearing when injured.

상기의 목적을 달성하기 위하여 본발명은,In order to achieve the above object, the present invention,

하측 베어링이 결합되는 베어링하우징의 베이링압입홈에 하측베어링의 외륜이 부상될수 있도록 연장홈을 형성하고 상기의 연장홈에는 부상되는 하측베어링의 외륜에 탄력을 부여할 수 있는 보압탄성부재를 결합시키면 본발명의 목적을 달성할 수 있게 된다.An extension groove is formed in the bearing press groove of the bearing housing to which the lower bearing is coupled so that the outer ring of the lower bearing can be injured, and the extension groove combines a pressure-elastic member that can give elasticity to the outer ring of the lower bearing. It is possible to achieve the object of the present invention.

직결식 세탁기(120)의 세탁공정과 탈수공정을 수행하는 세탁내조(116)의 회전시에 발생되는 구동축(106)의 부상력에 의해 하측베어링(110)의 외륜(112)이 내륜(111)과 함께 부상할 수 있도록 베어링하우징(101)의 결합공(102)하측부에 형성된 베어링압입홈(103)으로 연장 형성되는 연장홈(104)과,The outer ring 112 of the lower bearing 110 is the inner ring 111 due to the floating force of the drive shaft 106 generated during the rotation of the washing inner tank 116 which performs the washing process and the dehydration process of the direct-type washing machine 120. And extending groove 104 is formed to extend to the bearing pressing groove 103 formed in the lower portion of the coupling hole 102 of the bearing housing 101, so that it can rise with,

상기 연장홈(104)으로 결합되어 하측베어링(110)에 작용되는 충격을 탄력에 의해 흡수하는 동시에 내륜(111)과 외륜(112)이 함께 부상되는 하측베어링(110)에 탄력을 주어 소음의 발생을 막을수 있도록 하기 위한 보압탄성부재(105)를 구비한 구성이다.It is coupled to the extension groove 104 to absorb the impact acting on the lower bearing 110 by the elasticity and at the same time give the elasticity to the lower bearing 110 in which the inner ring 111 and the outer ring 112 are raised together to generate noise It is a configuration provided with a pressure-elastic elastic member 105 to prevent the.

그리고, 상기 구동축(106)에 상,하측베어링(109)(110)을 결합하기 위하여 형성되는 상,하측걸림턱(107)(108)의 길이(L1)는 상측 베어링(107)의 두께(t1)와 상측베어링(107)의 하단부에서 연장홈(104)까지의 길이(L2) 그리고 연장홈(104)에서 하측베어링(110)의 상단부까지의 길이(L3)를 합한 것 보다 같거나 길게 형성시켯다.The length L1 of the upper and lower locking jaws 107 and 108 formed to couple the upper and lower bearings 109 and 110 to the drive shaft 106 is the thickness t1 of the upper bearing 107. ) And the length L2 from the lower end of the upper bearing 107 to the extension groove 104 and the length L3 from the extension groove 104 to the upper end of the lower bearing 110 are the same or longer than the sum. I broke it.

이와같이된 본발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above is as follows.

먼저, 세탁물을 직결식 세탁기(120)의 세탁내조(116)에 투입을 시킨 뒤 작동보턴을 누르면 급수가 이루어지게 된다.First, the laundry is put into the washing tank 116 of the direct-type washing machine 120, and then press the operation button is made water supply.

그리고, 상기의 세탁내조(116)내부로 급수가 완료되면 모우터(117)가 작동하게 된다.When the water supply is completed inside the washing tub 116, the motor 117 is operated.

즉, 상기 모우터(117)의 스테이터(118)가 베어링하우징(101)에 결합된 상태에서 전기력을 발생시키기 때문에 로터(119)가 회전을 하게 된다.That is, the rotor 119 rotates because the stator 118 of the motor 117 generates an electric force in a state coupled to the bearing housing 101.

또한, 상기 로터(119)의 회전에 의해 로터(119)에 결합된 구동축(106)이 베어링 하우징(101)에 결합된 상,하측베어링(109)(110)에 의해 원활한 회전을 하게 된다.In addition, the drive shaft 106 coupled to the rotor 119 by the rotation of the rotor 119 is smoothly rotated by the upper and lower bearings 109 and 110 coupled to the bearing housing 101.

따라서, 상기 구동축(106)의 회전에 의해 구동축(106)과 연결된 세탁내조(116)가 회전되면서 세탁날개에 의해 세탁물을 세탁할 수 있게 된다.Therefore, the laundry inner tub 116 connected to the drive shaft 106 is rotated by the rotation of the drive shaft 106, so that the laundry can be washed by the washing blade.

한편, 상기의 구동축(106)과 세탁내조(116)의 회전이 이루어지면 구동축(106)이 원심력에 의해 상측으로 상승하게 되는 부상력이 발생하게 된다.On the other hand, when the drive shaft 106 and the washing inner tub 116 is rotated, the driving force of the drive shaft 106 to rise upward by the centrifugal force is generated.

이때, 상기 구동축(106)의 하측 걸림턱(108)에 걸리면서 결합되어 있는 하측베어링(110)의 내륜(111)도 구동축(106)을 따라 상측으로 부상하게 된다.At this time, the inner ring 111 of the lower bearing 110 coupled to the lower locking jaw 108 of the drive shaft 106 also floats upward along the drive shaft 106.

그리고, 상기 내륜(111)의 부상에 의해 볼(113)은 물론이고 외륜(112)도 베어링압입홈(103)내에 형성된 연장홈(104)으로 상승하게 된다.In addition, due to the rise of the inner ring 111, the outer ring 112 as well as the ball 113 is raised to the extension groove 104 formed in the bearing pressing groove 103.

상기와 같이 연장홈(104)내에서 상승되는 하측베어링(110)의 외륜(112)은 연장홈(104)내에 결합되어 있는 보압탄성부재(105)를 압축하게 되는 동시에 상기의 외륜(112)은 보압탄성부재(105)의 탄력에 의한 반력도 받게 된다.The outer ring 112 of the lower bearing 110, which is raised in the extension groove 104 as described above, compresses the pressure-resilient member 105 coupled to the extension groove 104, and the outer ring 112 is Reaction force due to the elasticity of the holding elastic member 105 is also received.

따라서, 상기 구동축(106)의 상승에 따라 부상되는 하측베어링(110)의 외륜(112)을 보압탄성부재(105)가 탄력으로 받쳐주고 잇는 상태가 되기 때문에 하측베어링(110)으로 전달되는 충격은 보압탄성부재(105)에 의해 흡수되어진다.Therefore, the shock transmitted to the lower bearing 110 because the pressure-elastic member 105 is elastically supporting the outer ring 112 of the lower bearing 110 that rises as the drive shaft 106 rises. It is absorbed by the pressure-sensitive elastic member 105.

또한, 상기 하측베어링(110)의 외륜(112)은 내륜(111)과 함께 부상되면서 보압탄성부재에 의해 탄력을 부여 받기 때문에 보올(113)에 작용되는 내,외륜(111)(112)의 전단력을 최소화 시킬수 있게 되므로 소음을 최소한으로 억제시킬수 게 된다.In addition, since the outer ring 112 of the lower bearing 110 is injured together with the inner ring 111 and is given elasticity by the holding elastic member, the shear force of the inner and outer rings 111 and 112 acting on the bowl 113. It is possible to minimize the noise to minimize the noise.

상기와 같이 보압탄성부재(105)에 의해 하측베어링(110)으로 전달되는 충격력의 흡수작용과 전단력의 최소화에 따는 소음의 억제효과에 의해 직결식 세탁기(120)의 조용한 구동을 얻을수 있고 베어링(109)(110)의 수명을 연장시킬수 있게 된다.As described above, a quiet driving of the direct-type washing machine 120 can be obtained by the suppression effect of the impact force transmitted to the lower bearing 110 by the pressure-elastic elastic member 105 and the noise suppression according to the minimization of the shear force and the bearing 109. It is possible to extend the life of (110).

그리고, 상기 구동축(106)에 상,하측베어링(109)(110)을 결합하기 위하여 형성되는 상,하측걸림턱(107)(108)의 길이(L1)는 상측 베어링(107)의 두께(t1)와 상측베어링(107)의 하단부에서 연장홈(104)까지의 길이(L2) 그리고 연장홈(104)에서 하측베어링(110)의 상단부까지의 길이(L3)를 합한것 보다 같거나 길게 형성시킴으로서 연장홈(104)내의 보압탄성부재(105)가 탄력을 충분하게 발휘할수 있도록 배려하였다.The length L1 of the upper and lower locking jaws 107 and 108 formed to couple the upper and lower bearings 109 and 110 to the drive shaft 106 is the thickness t1 of the upper bearing 107. ) And the length L2 from the lower end of the upper bearing 107 to the extension groove 104 and the length L3 from the extension groove 104 to the upper end of the lower bearing 110 are equal to or longer than the sum. Consideration was made so that the holding elastic member 105 in the extension groove 104 can sufficiently exhibit elasticity.

이와같이된 본발명은, 하측 베어링이 결합되는 베어링하우징의 베이링압입홈에 하측베어링의 외륜이 부상될 수 있도록 연장홈을 형성하고 상기의 연장홈에는 부상되는 하측베어링의 외륜에 탄력을 부여할 수 있는 보압탄성부재를 결합시킴으로서The present invention as described above, an extension groove is formed so that the outer ring of the lower bearing can be raised in the bearing indentation groove of the bearing housing to which the lower bearing is coupled, and the extension groove can give elasticity to the outer ring of the lower bearing to be raised. By combining a pressure-sensitive elastic member

직결식 세탁기의 구동축이 회전되면서 부상시 하측베어링으로 작용되는 충격을 흡수하는 동시에 상기 베어링에서 발생되는 소음 등을 막을 수 있게 되므로 조용한상태의 구동을 얻을 수 있고 베어링의 수명을 연장시킬수 있는 유용한 효과를 갖는다.As the drive shaft of the direct-type washing machine rotates, it absorbs the shock acting on the lower bearing when injured and prevents the noise generated from the bearings. Therefore, it is possible to obtain a quiet driving and extend the life of the bearing. Have
