Description
본 발명은 드럼세탁기의 캔밸런서에 관한 것으로, 더욱 상세하게는 회전조 측면에 부착되어 밸런스를 유지시키는 캔밸런서의 제조과정시 강구체가 내장된 레이스 내부로 오일이 정확하게 주입되었는지를 측정하는 캔밸런스의 오일주입량 측정방법에 관한 것이다.The present invention relates to a can balancer for a drum washing machine, and more particularly, to a can balance for measuring whether oil is accurately injected into a race in which a steel sphere is embedded during the manufacturing process of a can balancer attached to a side of a rotating tank to maintain a balance. It relates to a method of measuring the oil injection amount.
일반적으로 드럼세탁기는 드럼형상을 가진 회전조의 회전으로 생긴 낙차에 의해 세탁이 수행되는 것으로써, 미리 입력된 프로그램에 따라 세탁과 헹굼, 탈수가 이루어진다. 이러한 드럼세탁기는 탈수 행정중에 세탁물의 편심에 의해 심한 진동과 소음이 발생될 수 있기 때문에, 드럼세탁기에서의 밸런싱장치는 필수적이다. 도 1은 종래 드럼세탁기의 전체적인 구조를 개략적으로 보인 사시도이다.In general, the washing machine is a washing machine is performed by the drop caused by the rotation of the rotating tub having a drum shape, washing and rinsing, dehydration is performed according to a pre-programmed. Since such a drum washing machine can generate severe vibrations and noises due to eccentricity of laundry during the dehydration stroke, a balancing device in the drum washing machine is essential. 1 is a perspective view schematically showing the overall structure of a conventional drum washing machine.
종래 드럼세탁기는 이에 도시한 바와 같이, 외관을 이루는 사각통상의 하우징(1) 내부에 물이 담수되는 고정조(3)가 버퍼스프링(buffer spring,4)에 의해 매달려 설치되어 있고, 고정조(3)에 드럼형상의 회전조(2)가 내장되어 있다. 그리고 고정조(3)의 하부를 완충지지하는 충격흡수부재(5)가 마련된다.As shown in the related art, the drum washing machine is provided with a fixing tank (3) for fresh water in a rectangular cylindrical housing (1) forming an exterior, and is suspended by a buffer spring (4). 3) a drum-shaped rotating tub 2 is incorporated. And the shock absorbing member 5 for buffering the lower portion of the fixing tank 3 is provided.
회전조(2)는 하우징(1)의 저부에 마련된 구동모터(6)에 의해 구동되는데, 이를 위해 회전조(2) 후방에 풀리(미도시)가 구성되고 구동모터(6)와 밸트(미도시)를 매개로 연결되어 있어서 구동모터(6)의 회전력을 전달받게 된다. 회전조(2)에는 다수개의 탈수공(7)이 전면에 걸쳐 형성되어 있고, 내측으로 밴딩된 리프터(8)가 일정간격 이격되게 구성된다. 탈수공(7)은 세탁중에 물이 고정조(3)와 회전조(2) 사이를 유통하도록 안내하고, 탈수중에 회전조(2) 내의 세탈물로부터 원심 분리된 물이 고정조(3)로 빠져나가도록 안내한다. 리프터(8)는 세탁물을 끌어올려 낙하시키는 기능을 한다.The rotating tub 2 is driven by a drive motor 6 provided at the bottom of the housing 1. For this purpose, a pulley (not shown) is formed at the rear of the rotating tub 2, and the driving motor 6 and the belt (not illustrated) are provided. Is connected via a medium) to receive the rotational force of the drive motor (6). The rotating tub 2 is formed with a plurality of dehydration holes 7 over the entire surface, the lifter 8 bent inwardly is configured to be spaced apart by a predetermined interval. The dewatering hole (7) guides the water to flow between the holding tank (3) and the rotating tank (2) during washing, and the water centrifuged from the fines in the rotating tank (2) to the holding tank (3) during dewatering. Guide them out. The lifter 8 functions to lift and drop the laundry.
한편, 세탁과 탈수 중에 발생되는 진동을 방지하기 위해 고정조(3)에는 균형추(9a,9b)가 장착되어 있다. 이것은 고정조(3) 앞면에 부착된 전방균형추(9a)와 상측면에 부착된 상부균형추(9b)로 구별되며, 각각 11.4 kg, 12.2kg 정도의 무게를 가진다. 균형추(9a,9b)의 재질은 주철이며, 볼트(9c)를 이용하여 고정조(3)에 체결된다.On the other hand, in order to prevent vibration generated during washing and dehydration, the counterweight 3 is equipped with counterweights (9a, 9b). This is divided into the front balance weight (9a) attached to the front of the fixing tank (3) and the upper balance weight (9b) attached to the upper side, each having a weight of about 11.4 kg, 12.2kg. The material of the counterweight 9a, 9b is cast iron, and is fastened to the fixing tank 3 using the bolt 9c.
이와 같이 구성된 드럼세탁기는 세탁이나 탈수행정 중에 세탁물의 편심량 및 이에 따른 진동이 직접 고정조(3)에 전달되는데, 진동은 고정조(3) 앞면과 상측면에 부착된 균형추(9a,9b)에 의하여 상쇄된다. 즉, 불균일하게 회전운동하는 회전조(2)로부터 진동이 전달되어도 균형추(9a,9b)가 가지고 있는 자체무게에 의해 고정조(3)의 진동이 억제된다.The drum washing machine configured as described above is directly transmitted to the fixing tank 3 and the eccentric amount of the laundry during the washing or dehydrating stroke, and the vibration is applied to the counterweights 9a and 9b attached to the front and upper sides of the fixing tank 3. Offset by That is, even if vibration is transmitted from the rotating tank 2 which rotates unevenly, the vibration of the fixing tank 3 is suppressed by the own weight which the balance weight 9a, 9b has.
그러나, 편심량에 따른 진동은 단순히 균형추(9a,9b)의 무게에 의해서만 억제되고 감쇄되기 때문에, 균형추(9a,9b)의 무게가 가벼울 경우 밸런싱효과가 월등히 떨어지는 문제점이 있다. 또한 고정조(3)에 볼트(9c) 체결되어 있는 균형추(9a,9b)의 중량이 앞에서 설명한 바와 같이 매우 커서 설치작업이 난해하며, 전체적인 드럼세탁기의 무게가 가중되어 유통과정중에 취급하기 어려운 단점이 있다.However, since the vibration according to the amount of eccentricity is suppressed and attenuated only by the weights of the counterweights 9a and 9b, there is a problem in that the balancing effect is greatly reduced when the weights of the counterweights 9a and 9b are light. In addition, as the weight of the counterweights (9a, 9b) fastened to the fixing tank (3) (9c, 9b) is very large, as described above, the installation work is difficult, the weight of the overall drum washing machine is difficult to handle during the distribution process There is this.
이러한 문제를 해결하기 위해 최근의 드럼세탁기에는 회전조의 양측단부에 캔밸런서가 부착되어 있다. 캔밸런서는 레이스 내부에 구름운동하는 다수개의 강구체와 이의 구름운동을 안내하기 위해 소정량의 오일이 주입되어 이루어지는데, 강구체가 내장된 레이스에 정확한 양의 오일이 주입되었는지를 측정하는 방법이 용이하지 않아 캔밸런서의 불량여부를 판별하기가 곤란하다.In order to solve this problem, a recent drum washing machine has a can balancer attached to both ends of a rotating tank. Can balancer is composed of a large number of steel balls rolling in the race and a certain amount of oil is injected to guide the rolling motion of the race, and it is easy to measure whether the correct amount of oil is injected into the race in which the steel balls are embedded. It is difficult to determine whether the can balance is defective.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 드럼세탁기 회전조의 단부에 부착되는 레이스와 세탁물의 편심방향과 반대방향으로 자유롭게 이동할 수 있도록 레이스 내부에 채워지는 다수의 강구 및 오일로 이루어진 캔밸런서를 구성하여, 세탁이나 탈수행정중에 발생되는 세탁물의 편심량에 대응하여 효과적으로 균형을 유지하는데, 제품불량이 발생되지 않도록 캔밸런서에 정확한 오일량이 주입되었는지를 측정하는 드럼세탁기 캔밸런서의 오일주입량 측정방법을 제공하는 것이다.The present invention is to solve this problem, an object of the present invention consists of a plurality of steel balls and oil filled in the race to be freely moved in the direction opposite to the eccentric direction of the race and the laundry attached to the drum washing machine rotating tub The can balancer is effectively balanced in response to the eccentricity of the laundry generated during washing or dehydration, and the oil injection volume of the drum washer can balancer is measured to determine whether the correct amount of oil is injected into the can balancer to prevent product defects. To provide a way.

한편, 세탁이나 탈수과정 중에 세탁물의 편심에 의해 발생하는 불균형을 해소하기 위한 캔밸런서(40)가 원주방향으로 회전조(30)의 양측단부에 각각 마련된다. 캔밸런서(40)는 회전조(30)와 동심을 유지하며 고리형상의 공간부가 형성된 레이스(43a,43b), 레이스(43a,43b)의 내부에서 구름운동하도록 다수의 강구체(44) 등으로 이루어져 있다. 레이스(43a,43b)는 내측판(41)과 외측판(42)이 용접수단에 의해 결합되어 테두리부분에 2개가 마련되는데, 이것은 내향돌출된 인너레이스(43a)와 외향돌출된 아웃터레이스(43b)로 구별된다. 이러한 인너레이스(43a)와 아웃터레이스(43b)에는 각각 다수개의 강구체(44)와 오일이 채워져 있다.On the other hand, the can balancer 40 for eliminating the imbalance caused by the eccentricity of the laundry during the washing or dehydration process is provided at both end portions of the rotary tub 30 in the circumferential direction. The can balancer 40 has a plurality of steel balls 44 to maintain concentricity with the rotating tub 30 and to form rolling motions within the races 43a and 43b and the races 43a and 43b in which annular spaces are formed. consist of. The races 43a and 43b have two inner plates 41 and an outer plate 42 coupled to each other by welding means, which are provided at the rim, which is an inner race 43a projected inward and an outer race 43b projected outward. ). The inner race 43a and the outer race 43b are filled with a plurality of steel balls 44 and oil, respectively.
따라서 회전조(30)의 회전시 강구체(44)는 레이스(43a,43b) 내부의 천장면과 밀착되면서 편심방향과 반대방향으로 이동됨으로써 편심을 보상 회전조(30)의 완벽한 밸런싱이 유지되어 작동소음이 저감되는데, 이의 제조과정은 다음과 같다.Accordingly, when the rotating tub 30 rotates, the steel ball 44 is moved in the opposite direction to the eccentric direction while being in close contact with the ceiling surfaces inside the races 43a and 43b, thereby maintaining perfect balancing of the rotating tub 30. Operational noise is reduced, and its manufacturing process is as follows.
먼저, 캔밸런서(40)를 구성하는 외측판(42)에는 인너레이스(43a)와 아웃터레이스(43b)를 이루도록 레이스공간이 형성되어 있으며, 오일을 주입하기 위해 일정간격 이격된 오일주입구(45a,45b)와 공기배출구(46a,46b)가 천공되어 있다. 이 때, 오일주입구(45a,45b)와 공기배출구(46a,46b)는 인너레이스(43a)와 아웃터레이스(43b)에 각각 마련된다. 이러한 외측판(42)의 레이스공간에 적당량의 강구체(44)를 각각 투입하고 내측판(41)을 덮은 후, 용접수단을 통해 이들을 부착한다.First, a race space is formed on the outer plate 42 constituting the can balancer 40 to form the inner race 43a and the outer race 43b, and the oil inlets 45a spaced at regular intervals to inject oil. 45b) and air outlets 46a and 46b are drilled. At this time, the oil inlets 45a and 45b and the air outlets 46a and 46b are provided in the inner race 43a and the outer race 43b, respectively. Appropriate amount of steel balls 44 are put into the race space of the outer plate 42 and the inner plate 41 is covered, and then, these are attached through welding means.
그리고 오일주입구(45a,45b)와 공기배출구(46a,46b)를 통해 오일을 주입하는데, 이것은 강구체(44)의 구름운동을 원활하게 하며 마찰에 의한 마모손상을 방지하기 위함이다. 즉, 오일주입구(45a,45b)는 실제 오일을 주입하기 위한 것이고, 공기배출구(46a,46b)는 오일주입시 레이스(43a,43b) 내부에 있는 공기가 배출되어 오일주입을 용이하게 하기 위한 것인데, 이러한 오일주입구(45a,45b)를 통해 적당량의 오일을 채운 후 오일주입구(45a,45b)와 공기배출구(46a,46b)를 용접으로 실링하면 캔밸런서(40)가 완성된다.Oil is injected through the oil inlets 45a and 45b and the air outlets 46a and 46b, which facilitates rolling motion of the steel sphere 44 and prevents wear damage due to friction. That is, the oil inlets 45a and 45b are for injecting the actual oil, and the air outlets 46a and 46b are for injecting the air inside the races 43a and 43b to facilitate oil injection. After filling the appropriate amount of oil through the oil inlets 45a and 45b, the can balancer 40 is completed by sealing the oil inlets 45a and 45b and the air outlets 46a and 46b by welding.
한편, 이러한 캔밸런서(40)가 완벽한 제기능을 하기 위해서는 레이스(43a,43b) 내부에 적당량의 오일이 주입되어야 세탁물의 편심량을 강구체(44)가 원활하게 구름운동하면서 보상하는데, 이것은 오일주입량 측정방법을 통해 수행된다.On the other hand, in order for the can balancer 40 to function perfectly, an appropriate amount of oil must be injected into the race 43a and 43b to compensate the eccentricity of the laundry while rolling the body 44 smoothly, which is an oil injection amount. This is done through the measurement method.
본 발명에 따른 오일주입량 측정은 도 4에 도시한 바와 같이 콘트롤러(51)가 일체로 구성된 전자저울(50)을 통해 수행되는데, 도 4와 도 5를 참조하여 단계별로 자세히 설명하면 다음과 같다.The oil injection amount measurement according to the present invention is carried out through the electronic balance 50, the controller 51 is integrally configured as shown in Figure 4, described in detail with reference to Figures 4 and 5 as follows.
본 발명의 제1단계는 중량측정하는 단계(S1)로서, 앞에서 설명한 바와 같이 적당량의 강구체(44)를 투입하고 용접을 통해 접합된 레이스(43a,43b)를 전자저울(50)을 통해 이의 중량(Wo)을 측정한다. 전자저울(50)의 콘트롤러(51)에는 이 때의 중량(Wo)이 표시되며, 또한 여기에는 레이스(43a,43b)에 이상적으로 주입되어야 할 오일량의 무게(WT)가 셋팅되어 있다. 중량을 측정한 레이스(43a,43b)에 별도의 오일주입장치(미도시)를 통해 적당량의 오일을 주입한다. 이 때, 인너레이스(43a)에는 통상적으로 108ℓ정도의 오일을 주입하고, 아웃터레이스(43b)에는 225ℓ정도의 오일을 주입하는 것이 바람직하다.The first step of the present invention is a step of measuring the weight (S1), as described above by introducing a suitable amount of steel sphere 44 and the race 43a, 43b bonded by welding through the electronic balance (50) Measure the weight (W o ). The controller 51 of the electronic balance 50 displays the weight W o at this time, and the weight W T of the amount of oil to be ideally injected into the races 43a and 43b is set here. . An appropriate amount of oil is injected into the laces 43a and 43b that are weighed through a separate oil injection device (not shown). At this time, it is preferable to inject about 108 liters of oil into the inner race 43a and to inject about 225 liters of oil into the outer race 43b.
제2단계는 오일이 주입된 상태의 레이스(43a,43b) 중량(W1)을 측정하는 단계이다(S2). 이 때의 무게(W1)는 오일주입장치를 통해 오일이 주입되어 있기 때문에 제1단계에서 측정된 중량(Wo)보다 오일주입량 만큼 중량(Woil)이 더 나가게 된다.The second step is to measure the weight (W 1 ) of the race 43a, 43b in the state of oil injection (S2). At this time, since the weight W 1 is injected through the oil injection device, the weight W oil goes out by the amount of oil injection than the weight W o measured in the first step.
마지막으로 제3단계는 제품불량 여부를 판단하는 판단단계이다(S3). 중량측정2단계(S2)에서 측정된 중량(W1)과 중량측정1단계(S1)에서 측정된 중량(Wo)의 차이값(Woil)이 발생되는데, 이 차이값(Woil)이 주입된 오일량의 무게이다. 차이값(Woil)이 콘트롤러(51)에 미리 설정되어 있는 최적의 오일주입량 무게(WT)와의 오차범위 이내인지를 비교하고, 오차범위를 벗어나는 경우 불량으로 처리한다. 이러한 차이값(Woil)은 콘트롤러(51)의 표시부에 미리 셋팅된 오일량의 무게(WT)와 함께 숫자로 표시되어 작업자가 육안으로 쉽게 확인할 수 있으며, 셋팅된 무게(WT)의 오차범위 이상인 경우에는 오일이 과도하게 주입된 상태이기 때문에 오일량을 줄여야하고, 이하인 경우에는 오일을 보충한다.Finally, the third step is a determination step of determining whether the product is defective (S3). The difference (W oil ) between the weight (W 1 ) measured in the weighing step (S2) and the weight (W o ) measured in the weighing step (S1) is generated, and the difference value (W oil ) is The amount of oil injected. Whether the difference value W oil is within an error range from the optimal oil injection amount weight W T previously set in the controller 51 is compared, and if it is out of the error range, it is treated as defective. This difference value (W oil ) is displayed numerically together with the weight (W T ) of the oil amount preset in the display unit of the controller 51, the operator can easily check with the naked eye, the error of the set weight (W T ) If it is above the range, the amount of oil should be reduced because the oil is excessively injected, and if it is below, refill the oil.
따라서 본 발명에 따른 오일주입량 측정방법을 통해 레이스(43a,43b)에 정확한 양의 오일을 주입할 수 있어서, 오일주입으로 인한 제품불량을 방지할 수 있다.Therefore, it is possible to inject the correct amount of oil into the lace (43a, 43b) through the oil injection amount measuring method according to the present invention, it is possible to prevent product defects due to oil injection.
이상에서 상세히 설명한 바와 같이, 본 발명이 적용되는 드럼세탁기는 드럼형상의 회전조 양측단부에 부착되는 레이스와 세탁물의 편심방향과 반대방향으로 자유롭게 이동할 수 있도록 레이스 내부에 채워지는 다수의 강구체 및 오일로 이루어진 캔밸런서를 구성하여 세탁이나 탈수행정중에 발생되는 세탁물의 편심량에 대응하여 효과적으로 균형을 유지하는데, 레이스에 주입되는 오일량을 오일주입량 측정방법을 통해 정확하게 측정함으로써 제품불량이 발생되지 않는다.As described in detail above, the drum washing machine to which the present invention is applied is provided with a plurality of steel balls and oils filled in the race to be freely moved in the opposite direction to the eccentric direction of the race and laundry attached to the drum-shaped rotating tub. It consists of a can balancer that effectively balances the amount of laundry generated during washing or dehydration administration, and effectively maintains the balance.However, the amount of oil injected into the race is accurately measured through an oil injection measuring method so that no product defects are generated.
