드럼세탁기의 구동기 장착구조{Structure for attaching driver of drum type washing machine}Structure for attaching driver of drum washing machine

본 발명은 드럼세탁기에 관한 것으로, 특히 드럼세탁기의 가변속모터의 구동을 제어하는 구동기를 드럼세탁기 내에 장착하기 위한 드럼세탁기의 구동기 장착구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum washing machine, and more particularly, to a driver mounting structure of a drum washing machine for mounting a driver for controlling the driving of a variable speed motor of a drum washing machine in a drum washing machine.

일반적으로, 드럼 세탁 방식은 세제와 세탁수 및 세탁물이 드럼 내에 투입된상태에서, 모터의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 손상이 거의 없고, 세탁물이 서로 엉키지 않으며, 두드리고 비벼빠는 세탁효과를 낼 수 있다.In general, the drum washing method is a method of washing the laundry using the friction force of the rotating drum and the laundry by receiving the driving force of the motor in a state in which detergent, washing water and laundry are put in the drum, there is almost no damage to the laundry, laundry These don't get tangled with each other and can be washed and pounded.

상기와 같은 종래의 일반적인 드럼세탁기의 구성을 첨부된 도면의 도 1을 참조하여 설명하면 다음과 같다.Referring to FIG. 1 of the accompanying drawings, the configuration of a conventional drum washing machine as described above is as follows.

도 1에 도시된 바와 같이, 드럼세탁기의 외형을 형성하는 캐비닛(1) 내측에 원통형의 터브(2; tub)가 설치되고, 상기 터브(2) 내측에는 원통형의 드럼(3)이 회전가능하게 설치된다.As illustrated in FIG. 1, a cylindrical tub 2 (tub) is installed inside the cabinet 1 forming the outer shape of the drum washing machine, and the cylindrical drum 3 is rotatable inside the tub 2. Is installed.

그리고, 상기 터브(2) 하부 일측에는 상기 드럼(3)을 회동시키기 위한 구동수단으로서 모터(5)가 설치되고, 상기 모터(5)에는 모터 풀리(51)가 축연결된다.A lower side of the tub 2 is provided with a motor 5 as a driving means for rotating the drum 3, and a motor pulley 51 is axially connected to the motor 5.

한편, 상기 드럼(3) 후방에는 구동축(31)이 설치되고, 상기 구동축(31) 후단에는 드럼 풀리(32)가 설치되는데, 이 드럼 풀리(32)는 동력전달요소인 벨트(6)를 매개로 상기 모터(5)에 연결된 모터 풀리(51)와 연결되어 회동하게 된다.Meanwhile, a driving shaft 31 is installed at the rear of the drum 3, and a drum pulley 32 is installed at the rear end of the driving shaft 31. The drum pulley 32 carries a belt 6 as a power transmission element. It is connected to the motor pulley 51 connected to the motor 5 to rotate.

그리고, 상기 캐비닛(1) 상부면 내측과 터브(2) 외주면 상부측 사이에는 터브(2)를 탄성적으로 지지하는 서스펜션 스프링(24; suspension spring)이 설치되고, 상기 캐비닛(1) 하부면 내측과 터브(2) 외주면 하부측 사이에는 탈수시 발생하는 터브(2)의 진동을 감쇠시키기 위한 댐퍼(25)가 설치된다.In addition, a suspension spring (24) for elastically supporting the tub (2) is installed between the inside of the upper surface of the cabinet (1) and the upper side of the outer peripheral surface of the tub (2), and the inside of the lower surface of the cabinet (1). And a damper 25 is provided between the tub 2 and the lower side of the outer circumferential surface to damp the vibration of the tub 2 generated during dehydration.

그러나, 상기와 같이 이루어진 종래의 드럼세탁기에서는 터브(2)의 후방에 드럼 풀리(32)와 모터 풀리(51) 및 구동축(31) 등 대부분의 구성요소들이 집중 설치되고, 모터(5)가 터브(2) 후방의 하부 일측에 고정되어 있으므로, 터브(2)의 후방부가 전방보다 많은 하중을 받게 되고, 이로 인해 터브(2) 내의 드럼(3)이 회동시 무게의 불균형에 의해 진동이 심하게 발생하게 된다.However, in the conventional drum washing machine made as described above, most components such as the drum pulley 32, the motor pulley 51 and the drive shaft 31 are concentrated at the rear of the tub 2, and the motor 5 is tub (2) Since it is fixed to one lower side of the rear side, the rear portion of the tub 2 receives more load than the front side, which causes severe vibration due to unbalance of weight when the drum 3 in the tub 2 rotates. Done.

따라서, 상기와 같은 터브(2) 후방과 전방과의 무게 불균형을 보정하기 위하여 상기 터브(2)의 전방 외주면에 철 또는 시멘트 등의 재질로 된 무거운 밸런스웨이트(26)를 설치해야 했는데, 이는 드럼세탁기 내에서 터브의 조립성을 저하시킴과 더불어 비용적인 측면에서도 바람직하지 못한 문제점이 있었다.Therefore, in order to correct the weight imbalance between the rear and the front of the tub 2, the heavy balance weight 26 made of a material such as iron or cement had to be installed on the front outer circumferential surface of the tub 2, which is a drum In addition to reducing the assembly of the tub in the washing machine there was an undesirable problem in terms of cost.

한편, 드럼세탁기의 드럼을 구동시키기 위한 구동수단으로서 드럼에 연결된 구동축에 직접 결합하는 직결식 모터를 사용하는 경우, 상기 직결식 모터가 터브의 후방 중심부에 설치되므로 어느 정도 무게의 불균형 문제는 해소되지만, 드럼세탁기 내에서 상기 직결식 모터를 구동하기 위한 구동기의 설치 공간을 별도로 마련해 주어야 하는 문제점이 있었다.On the other hand, when using a direct type motor that is directly coupled to the drive shaft connected to the drum as a driving means for driving the drum of the drum washing machine, since the direct motor is installed in the rear center of the tub, the problem of weight imbalance to some extent is eliminated. In the drum washing machine, there is a problem in that a separate installation space of a driver for driving the direct motor is provided.

이에 본 발명은 상기와 같은 문제점들을 감안하여 안출된 것으로, 터브에 밸런스웨이트를 장착하지 않고서도 무게의 불균형문제를 해소함과 동시에, 모터의 구동기를 드럼세탁기 내에서 설치하기 용이하도록 된 드럼세탁기의 구동기 장착구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, and solves the weight imbalance problem without installing the balance weight on the tub, and at the same time, it is easy to install the driver of the motor in the drum washing machine. The purpose is to provide a mounting structure.

도 2에 도시된 바와 같이, 세탁수를 저장하는 원통형의 터브(20) 내에 원통형의 드럼(3)이 회전가능하게 설치되고, 이 드럼(3)의 후벽 중심부에는 구동축(31)의 일단이 고정되게 설치되며, 이 구동축(31)은 터브(20)의 후방 중심부를 관통하여 BLDC모터(Brushless DC Motor) 또는 SRM모터와 같은 가변속모터(500)와 직결된다.As shown in FIG. 2, a cylindrical drum 3 is rotatably installed in a cylindrical tub 20 for storing wash water, and one end of the driving shaft 31 is fixed to a central portion of the rear wall of the drum 3. The drive shaft 31 penetrates the rear center of the tub 20 and is directly connected to a variable speed motor 500 such as a brushless DC motor or an SRM motor.

또한, 상기와 같은 가변속모터(500)는 이 가변속모터(500)에 연결되어 작동을 제어하는 구동기(600)를 필요로 하는데, 이 구동기(600)는 드럼세탁기 내에서 터브(20)의 무게의 불균형을 해소하기 위하여 터브(20)의 전방 일측에 장착되고, 바람직하기로는 터브(20)의 전방 상단부에 장착된다.In addition, the variable speed motor 500 as described above requires a driver 600 that is connected to the variable speed motor 500 to control the operation, the driver 600 of the weight of the tub 20 in the drum washing machine. In order to eliminate the imbalance, it is mounted on the front one side of the tub 20, and preferably mounted on the front upper end of the tub 20.

한편, 상기 구동기(600)는 그의 양 측면 및 전,후방면 하단에 다수의 체결용 브라켓(610)이 형성되고, 이 체결용 브라켓(610)에는 구멍(611)이 형성되어 있는 바, 나사 등의 체결수단(미도시)이 상기 체결용 브라켓(610)의 구멍(611) 및 터브(20) 외측면에 형성된 체결용 보스(201)를 통해 삽입되어 결합됨으로써 구동기(600)가 터브(20)에 장착된다.On the other hand, the driver 600 has a plurality of fastening brackets 610 are formed on both sides and lower ends of the front and rear surfaces, and the fastening brackets 610 are formed with holes 611, bars, screws, and the like. The fastening means (not shown) is inserted through the fastening boss 201 formed in the hole 611 and the tub 20 outer surface of the fastening bracket 610 is coupled to the driver 600 tub 20 Is mounted on.

따라서, 상기와 같이 가변속모터(500)를 구동시키는 구동기(600)가 터브(20)전방부에 장착됨으로써 별도의 밸런스웨이트(26; 도 1참조)를 장착할 필요없거나, 혹은 적은 밸런스웨이트 만으로 터브(20)의 무게의 균형을 잡을 수 있게 되는 것이다.Therefore, as the driver 600 for driving the variable speed motor 500 is mounted to the front of the tub 20 as described above, it is not necessary to install a separate balance weight 26 (see FIG. 1) or the tub with only a few balance weights. 20 will be able to balance the weight.

이하, 상기와 같이 구성된 드럼세탁기의 작동에 대해 설명한다.Hereinafter, the operation of the drum washing machine configured as described above will be described.

사용자가 세탁을 위하여 드럼세탁기에 전원을 인가한 후, 세탁물의 양과 종류에 따라 세탁수의 양과 세탁시간 및 세탁종류를 선택하면, 드럼세탁기는 마이콤(미도시)의 제어에 의해 자동으로 세탁을 수행하게 된다.After the user applies power to the drum washing machine for washing, and selects the amount of washing water, washing time, and washing type according to the amount and type of laundry, the drum washing machine performs washing automatically under the control of the microcomputer (not shown). Done.

여기서, 상기 마이콤은 설정된 세탁순서에 따라 상기 터브(20)에 설치된 구동기(600)를 동작시키게 되고, 이 구동기(600)의 동작에 의해 상기 터브(20) 후방에서 구동축(31)에 직결된 가변속모터(500)를 동작시키게 된다.Here, the micom operates the driver 600 installed in the tub 20 according to the set washing order, and the variable speed directly connected to the drive shaft 31 from the rear of the tub 20 by the operation of the driver 600. The motor 500 is operated.

이어서, 상기 가변속모터(500)의 동작에 의해 구동축(31)이 회전하면서 터브(20) 내의 드럼(3)을 회전시켜 세탁을 수행하게 되는데, 이와 같이 상기 드럼(3)이 회전하면서 세탁을 수행할 때 드럼(3)에서 발생하게 되는 진동이 구동축(31)을 통해 터브(20)에 전달되게 된다.Subsequently, while the drive shaft 31 is rotated by the operation of the variable speed motor 500, the drum 3 in the tub 20 is rotated to perform washing. In this way, the drum 3 rotates to perform washing. When the vibration generated in the drum 3 is transmitted to the tub 20 through the drive shaft (31).

이 때, 상기 터브(20) 자체에서 무게의 균형이 잡혀있지 않다면, 상기 드럼(3)에서 작은 진동이 발생하여 터브(20)에 전달되더라도 터브(20)에서는 그 진동이 점차적으로 증폭되어 드럼세탁기 전체에 영향을 줄 수 있으나, 본 발명 드럼세탁기는 터브(20) 전방에 장착된 구동기(600)에 의해 전체적인 균형이 잡혀 있으므로 상기와 같이 진동이 증폭되는 등의 현상은 일어나지 않게 되는 것이다.At this time, if the weight is not balanced in the tub 20 itself, even if a small vibration generated in the drum 3 is transmitted to the tub 20, the vibration is gradually amplified in the tub 20 drum washing machine Although it may affect the whole, the drum washing machine of the present invention is balanced overall by the driver 600 mounted to the front of the tub 20, so that the phenomenon such as amplification of vibration will not occur.

한편, 본 발명은 앞에서 설명한 실시예에 국한되지 아니하며, 본 발명의 요지를 벗어나지 않는 범위 내에서 다양한 변경 및 실시가 가능하다.On the other hand, the present invention is not limited to the above-described embodiment, and various changes and implementations can be made without departing from the gist of the present invention.

이상에서와 같이, 본 발명에 따르면 드럼세탁기의 드럼을 회동시키기 위한 구동수단으로서 가변속모터가 드럼의 구동축에 직결되고, 상기 가변속모터를 구동시키는 구동기가 터브의 전방 일측에 장착되므로, 드럼세탁기 내에서 가변속모터의 구동기를 장착하기 위한 별도의 공간을 마련할 필요가 없으며, 터브에 별도의 밸런스웨이트를 추가로 장착할 필요가 없게 되거나, 밸런스웨이트의 무게를 줄일 수 있게 된다.As described above, according to the present invention, since the variable speed motor is directly connected to the driving shaft of the drum as a driving means for rotating the drum of the drum washing machine, and the driver for driving the variable speed motor is mounted on one front side of the tub, There is no need to provide a separate space for mounting the drive of the variable speed motor, there is no need to install a separate balance weight on the tub, or to reduce the weight of the balance weight.
