Description
본 발명은 드럼세탁기에 관한 것으로서, 더 상세하게는 건조겸용 드럼세탁기의 팬 어셈블리에 관한 것이다.The present invention relates to a drum washing machine, and more particularly to a fan assembly of a dry drum washing machine.
일반적으로 도 1에 도시된 바와 같이, 드럼 세탁기는 본체(1)와, 상기 본체 내에 댐퍼(6)와 스프링(7에 의해 지지된 외조(2)와, 상기 외조 내에 위치하며 세탁물을 넣을 수 있는 원통형상의 내조(3)로 크게 나뉘어지고, 상기 내조 내에 세탁물을 세탁하기 위해 구동수단에 의해 구동력이 전달된다.In general, as shown in FIG. 1, a drum washing machine includes a main body 1, an outer tub 2 supported by a damper 6 and a spring 7 within the main body, and a laundry placed in the outer tub to accommodate laundry. It is largely divided into a cylindrical inner tub 3, and a driving force is transmitted by the driving means to wash the laundry in the inner tub.
그리고 상기 구동수단은 상기 내조(3) 후방 중앙의 축에 설치된 풀리(도시생략)와, 상기 외조하단 일측에 장착된 모터(4)를 상호 밸트(5)로 연결하여 상기 모터(4)의 동력을 내조 축(도시생략)에 전달하도록 구성된 것과, 로터와 스테이터에 의해 발생한 동력을 내조 축에 직접 전달하도록 구성된 것과, 그 외 다양한 방법에 의해 동력을 내조 축에 전달하는 것이 있다.In addition, the driving means is connected to the pulley (not shown) installed on the shaft of the rear center of the inner tank (3) and the motor (4) mounted on one side of the bottom of the outer tank by mutual belt (5) to drive the power of the motor (4) Is configured to transmit power to the inner cylinder shaft (not shown), configured to transmit power generated by the rotor and the stator directly to the inner cylinder shaft, and to transmit the power to the inner shaft by a variety of other methods.
한편, 상기 드럼세탁기는 내조(3)가 세워진 상태로 회전하는 펄세이터 세탁기에 비해 전체 높이를 줄일 수 있을 뿐만 아니라 세탁용량을 더 늘릴 수 있고, 포꼬임 등의 문제가 거의 발생되지 않으므로 그 수요가 점점 더 늘어나고 있는 추세에 있다.On the other hand, the drum washing machine can not only reduce the overall height compared to the pulsator washing machine that rotates in the state in which the inner tank (3) is standing, but also increase the washing capacity, and the demand is rarely generated. There is an increasing trend.
상기와 같이 구성된 드럼 세탁기는 다음과 같은 동작을 수행한다.The drum washing machine configured as described above performs the following operation.
내조(3) 안으로 세탁하고자 하는 세탁물을 넣고, 세제통(8)에 세제를 넣은 상태에서 콘트롤부에 구비된 세탁모드를 선택하면 세탁행정▶ 헹굼행정▶ 탈수행정이 연속적으로 이루어지면서 세탁이 완료된다.Put the laundry to be washed into the inner tank (3), and when the detergent mode is put into the detergent container (8), if the washing mode provided in the control unit is selected, the washing stroke ▶ rinsing stroke ▶ dehydration stroke is continuously made and washing is completed.
즉 세탁모드가 선택되면, 급수장치가 작동하여 외조(2) 내에 회전 가능하게 설치되어 있는 내조(3) 안으로 세탁에 사용될 물을 급수하고, 상기 급수된 물이 적정수위 만큼 채워지고 나면 급수는 중단됨과 동시에 구동수단이 정, 역 구동을 반복적으로 행한다.That is, if the washing mode is selected, the water supply device is operated to supply water to be washed into the inner tank (3) rotatably installed in the outer tank (2), the water supply is stopped after the water is filled by the appropriate level. At the same time, the driving means repeatedly performs the forward and reverse driving.
이와 같이 구동수단이 정, 역 구동을 행하면, 이 구동수단의 구동력은 감속수단에 의해 감속되어 내조(3)로 인가되고, 상기 구동력을 인가받은 내조(3)가 정, 역회전함에 따라 발생되는 수류로 인해 세탁물에 묻어 있는 때가 수류 및 내조(3)와의 마찰에 의해 분해되거나, 세제에 의해 분해되어 세탁된다.When the driving means performs forward and reverse driving as described above, the driving force of the driving means is decelerated by the deceleration means and applied to the inner tank 3, which is generated as the inner tank 3 applied with the driving force rotates forward and reverse. When the water is buried in the laundry due to the water flow, it is decomposed by the water flow and friction with the inner tank 3, or is decomposed by the detergent and washed.
상기 세탁행정이 완료되고 나면, 세탁행정시와 동일한 과정을 거치면서 헹굼을 수행하고, 헹굼행정이 완료되고 나면 곧바로 탈수행정이 수행되는데, 상기 탈수 행정시에는 배수수단이 작동하여 내조(3) 내에 채워져 있는 물을 완전히 배수한 다음 구동수단이 구동되고, 이 구동수단의 구동력은 감속되지 않은 상태 그대로 상기 내조(3)로 전달되므로 내조(3)가 고속으로 회전함에 따라 원심력에 의해 세탁물에 함유된 수분이 빠져 나오면서 탈수가 수행된다.After the washing stroke is completed, the rinsing is performed while going through the same process as the washing stroke, and after the rinsing stroke is completed, the dehydration stroke is performed immediately. After completely draining the filled water, the driving means is driven, and the driving force of the driving means is transmitted to the inner tank 3 as it is not decelerated, so that the inner tank 3 is rotated at a high speed to be contained in the laundry by centrifugal force. Dehydration is carried out as the moisture escapes.
한편, 도 2에 도시된 바와 같이, 건조를 겸하는 드럼세탁기는 상기 탈수행정이 끝난 후 세탁물을 건조시키는 건조장치가 부가된 것으로서, 상기 건조장치의 구성 및 작동원리는 다음과 같다.On the other hand, as shown in Figure 2, the drum washing machine combines drying as a drying device for drying the laundry after the dehydration operation is added, the configuration and operation principle of the drying device is as follows.

It consists of a fan assembly 20 for blowing air to be circulated on the flow path, and an inner tank 3 installed on the circulation flow path and containing laundry to be dried.
그리고 건조시 상기 내조(3) 내에 들어있는 세탁물을 회전시키면서 상기 세탁물을 건조시키기 위해 상기 내조에 회전력을 인가하는 모터(4)와, 상기 모터와 상기 내조를 연결하는 밸트(5)로 구성된다.And it is composed of a motor (4) for applying a rotational force to the inner tank to dry the laundry while rotating the laundry contained in the inner tank (3) during drying, and a belt (5) connecting the motor and the inner tank.
그리고 상기 순환유로을 더 상세하게 설명하면 다음과 같이 나누어진다.And in more detail the circulation flow path is divided as follows.
상기 드라이히터(11)에서 발산된 열을 내조(3)로 전달하는 건조유로(12)와, 상기 건조유로에서 전달된 열에 의해 내조의 세탁물을 건조시키는 곳인 외조(2)와, 상기 세탁물이 건조되면서 발생되는 수증기를 포함한 열기가 유동되어 다시 히터로 전달되는 증기유로(13)로 나뉘어져 한 사이클을 이룬다.The drying passage 12 which transfers the heat radiated from the dry heater 11 to the inner tank 3, the outer tank 2 which is a place to dry the laundry of the inner tank by the heat transferred from the drying passage, and the laundry is dried. Heat is generated, including the steam generated as it flows and is divided into a steam flow passage 13 which is delivered to the heater to form a cycle.

Grease was applied between the rotation center of the blowing fan and the fan motor housing so as to smoothly rotate the blowing fan.
그리고 상기 팬모터몸체(22)와 상기 팬모터덮개(23)는 고정나사(26)에 의해 고정되어 있다.The fan motor body 22 and the fan motor cover 23 are fixed by a fixing screw 26.
한편, 도 3에 도시된 바와 같이, 상기 팬모터(21)에 대해 상세하게 설명하면 다음과 같다.Meanwhile, as shown in FIG. 3, the fan motor 21 will be described in detail as follows.
