Description
본 발명은 드럼세탁기에 관한 것으로, 더욱 상세하게는 회전조와 고정조 사이에 설치되어 세탁수를 가열 삶아빠는 드럼세탁기의 전기히터 설치구조에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to an electric heater installation structure of the drum washing machine is installed between the rotating tank and the fixing tank heating the washing water.
일반적으로 드럼세탁기는 드럼형상을 가진 회전조의 회전으로 생긴 낙차에 의해 세탁이 수행되는 것으로써, 미리 입력된 프로그램에 따라 세탁과 헹굼, 탈수 건조가 자동적으로 이루어진다. 또한 세탁하고자 하는 세탁물에 따라 찌든세탁, 표준세탁, 울세탁으로 나뉘어 세탁을 할 수 있다. 도 1은 이러한 종래 드럼세탁기의 전체적인 구조를 보인 개략도이다.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, rinsing, dehydration drying is automatically performed according to a pre-programmed. In addition, depending on the laundry to be washed can be divided into washing, standard washing, wool washing. 1 is a schematic view showing the overall structure of such a conventional drum washing machine.
종래 드럼세탁기는 이에 도시한 바와 같이, 외관을 이루는 사각통상의 하우징(1) 내부에 물이 담수되는 고정조(2)가 버퍼스프링(buffer spring,4)에 의해 매달려 설치되어 있고, 고정조(2)에 드럼형상의 회전조(3)가 내장되어 있다. 그리고 고정조(2)의 하부를 완충지지하는 충격흡수부재(4a)가 마련된다.As shown in the related art, the drum washing machine is provided with a fixing tank (2) for fresh water in a rectangular cylindrical housing (1) forming an exterior by hanging with a buffer spring (4). The drum-like rotary tub 3 is built in 2). And the shock absorbing member (4a) for buffering the lower portion of the fixing tank (2) is provided.
회전조(3)는 고정조(2)의 최하단부에 매달려 설치된 구동모터(5)에 의해 구동되는데, 이를 위해 고정조(2) 측단부위에 회전조(3) 중심부와 결합된 회전축(6)과 풀리(6a)가 구성되고, 풀리(6a)가 구동모터(5)와 밸트(6b)를 매개로 연결되어 있어서 구동모터(5)의 회전력을 전달받게 된다. 회전조(3)에는 다수개의 탈수공(3a)이 전면에 걸쳐 형성되어 있고, 내측으로 돌출되게 이루어진 리프터(미도시)가 120도 간격으로 구성된다. 탈수공(3a)은 세탁중에 물이 고정조(2)와 회전조(3) 사이를 유통하도록 안내하고, 탈수중에 회전조(3) 내의 세탈물로부터 원심 분리된 물이 고정조(2)로 빠져나가도록 안내한다. 리프터(미도시)는 세탁물을 끌어올려 낙하시키는 기능을 한다.The rotating tub 3 is driven by a driving motor 5 mounted on the lowermost end of the fixed tub 2, and for this purpose, the rotating shaft 6 coupled with the center of the rotating tub 3 at the side end of the fixed tub 2 is provided. The pulley 6a is configured, and the pulley 6a is connected to the driving motor 5 and the belt 6b to receive the rotational force of the driving motor 5. The rotating tank 3 is formed with a plurality of dehydration holes (3a) over the entire surface, the lifter (not shown) made to project inward is configured at intervals of 120 degrees. The dewatering hole 3a guides the water to flow between the fixing tank 2 and the rotating tank 3 during washing, and the water centrifuged from the fines in the rotating tank 3 to the fixing tank 2 during dewatering. Guide them out. The lifter (not shown) serves to lift and drop the laundry.
한편, 회전조(3) 하단부위에는 전기히터(7)가 설치되어 찌든세탁물을 삶아빠는 기능을 할 수 있다. 즉, 회전조(3)와 고정조(2) 사이의 하단부위 공간에 전기히터(7)가 내장되어 있어서, 세탁수를 약 90˚정도까지 가열하여 세탁물을 삶아빨게 된다.On the other hand, the lower portion of the rotary tub (3) the electric heater (7) is installed can function to boil off the washed laundry. That is, the electric heater (7) is built in the lower space between the rotary tank 3 and the fixed tank (2), the washing water is heated to about 90 degrees to boil the laundry.
이와 같이 구성된 드럼세탁기는 회전조(3)에 세탁물을 넣고 세탁을 수행하는데, 세탁행정 중에는 회전조(3)가 구동모터(5)의 회전력을 밸트(6b)를 매개로 전달받아 회전한다. 회전조(3)의 회전운동에 의해 내부에 있는 세탁물은 뒹굴거나 리프터(미도시)에 의해 끌어올려져 낙하됨으로써 세탁된다. 그리고 탈수행정중에는 회전조(3)의 고속회전에 의해 세탁물이 탈수된다. 탈수된 물은 탈수공(3a)을 통해 고정조(2)로 빠져나가고, 계속하여 배수장치(미도시)에 의해 외부로 배수된다.The drum washing machine configured as described above puts laundry into the rotating tub 3 and performs washing. The rotating tub 3 rotates while receiving the rotational force of the driving motor 5 through the belt 6b. The laundry in the interior is rotated by the rotary motion of the rotating tub 3 or is lifted by a lifter (not shown) to be washed by being dropped. And during the dehydration administration, the laundry is dewatered by the high speed rotation of the rotating tub (3). The dewatered water exits to the fixed tank 2 through the dehydration hole 3a, and is subsequently drained to the outside by a drainage device (not shown).
한편, 찌든세탁물을 세탁하는 경우에는 고정조(2)에 소정량의 세탁수를 급수하고, 회전조(3) 하단부위에 설치된 전기히터(7)에 전원을 공급하여 세탁수를 가열한다. 따라서 전기히터(7)에서 발생되는 열에 의해 세탁수가 가열되고, 이에 따라 세탁물이 삶아져 찌든때가 쉽게 빠진다.On the other hand, in the case of washing the washed laundry, a predetermined amount of washing water is supplied to the fixing tank 2, and power is supplied to the electric heater 7 provided at the lower end of the rotating tank 3 to heat the washing water. Therefore, the washing water is heated by the heat generated by the electric heater 7, and thus the laundry is boiled and steamed easily.
그러나 이러한 종래 드럼세탁기는 도 1에 도시한 바와 같이, 전기히터(7)가 회전조(3)와 고정조(2) 사이의 공간 하단부위에서 약간 올라온 위치에 설치되어 있기 때문에, 많은 양의 세탁수를 가열해야 하는 문제점이 있다.However, such a conventional drum washing machine, as shown in Figure 1, because the electric heater (7) is installed in a position slightly raised from the lower end of the space between the rotating tank (3) and the fixed tank (2), a large amount of washing water There is a problem that needs to be heated.
즉, 전기히터(7)가 공기중에 노출되지 않도록 세탁수위가 전기히터(7)보다 일정수위로 항상 높게 유지되어야만 과열되지 않는다. 따라서 약간 상측면부에 위치된 전기히터(7)가 항상 잠기도록 많은 세탁수를 급수하고, 이를 가열해야 하기 때문에 전기히터(7) 구동시간이 길어지게 된다. 또한, 이로 인해 세탁수 수위가 세탁물이 담겨지는 회전조(3) 최하단부보다도 높아짐으로써, 세탁물이 흡수하는 양까지도 감안하여 세탁수를 급수하여야 한다. 실제로 최대세탁용량이 6 Kg 인 드럼세탁기의 경우, 세탁물 삶는행정시 약 21ℓ정도의 세탁수가 필요하여, 전력낭비의 원인이 된다.That is, the washing water level must be always kept higher than the electric heater 7 at a certain level so that the electric heater 7 is not exposed to air so as not to overheat. Therefore, a lot of washing water is supplied to the electric heater (7) located slightly above the upper portion always locked, and the heating time of the electric heater (7) becomes long because it has to be heated. In addition, the washing water level is higher than the lowest end of the rotary tub 3 in which the laundry is contained, so that the washing water must be supplied in consideration of the amount absorbed by the laundry. In fact, a drum washing machine with a maximum washing capacity of 6 Kg requires about 21 liters of washing water when the laundry is boiled, causing power waste.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 주 목적은 고정조와 회전조 사이의 공간에 전기히터가 설치되어 세탁물을 삶아빠는 행정시 고정조에 담수된 세탁수를 가열하는데, 전기히터를 고정조 바닥면의 직상부공간에 가로방향으로 설치함으로써, 전기히터가 잠길정도의 최소량의 세탁수 활용이 가능 전력소비를 줄이는 드럼세탁기의 전기히터를 제공하는 것이다.The present invention is to solve this problem, the main object of the present invention is to install the electric heater in the space between the fixed bath and the rotating bath to heat the wash water fresh water in the fixed bath during the stroke to wash the laundry, the electric heater By installing in the horizontal direction immediately above the bottom of the fixing tank, it is possible to utilize the minimum amount of wash water enough to lock the electric heater to provide an electric heater of the drum washing machine to reduce the power consumption.
그리고 본 발명의 부 목적은 고정조 외부로 노출된 전기히터의 단자부에 일단부가 이와 접속되며 선단부에 피메일단자가 마련된 접속부재를 별도로 구성하여 와이어하네스와의 전기접속을 용이하게 하는 드럼세탁기의 전기히터를 제공하는 것이다.In addition, an object of the present invention is to provide an electric connection of a drum washing machine that facilitates electrical connection with a wire harness by separately configuring a connection member having one end connected to the terminal portion of the electric heater exposed to the outside of the fixing tank and having a female terminal provided at the front end thereof.

다음에는 이와 같이 구성된 본 발명에 따른 드럼세탁기의 작동 및 효과를 설명한다.Next will be described the operation and effect of the drum washing machine according to the invention configured as described above.
먼저, 사용자가 회전조(30) 내에 세탁물을 투입하고, 콘트롤부(50)를 조작하여 작동시키면, 세제가 용해된 세탁수가 고정조(20) 내부로 유입된다. 그리고 사용자가 선택한 세탁코스에 따라 세탁과 헹굼 및 탈수행정이 이루어진다. 즉, 표준세탁을 선택하게 되면, 회전조(30)가 구동모터(38)의 회전력을 밸트(37)를 매개로 전달받아 회전한다. 이에 따라 회전조(30) 내부에 있는 세탁물은 뒹굴거나 리프터(32)에 의해 끌어 올려져 낙하됨으로써 세탁이 수행된다. 탈수행정중에는 회전조(30)의 고속회전에 의해 세탁물이 탈수되며, 탈수된 물은 탈수공(31)을 통해 고정조(20)로 빠져나가 외부로 배수된다.First, when a user puts laundry into the rotating tub 30 and operates the control unit 50, the washing water in which detergent is dissolved is introduced into the fixing tub 20. In addition, washing, rinsing, and dehydration are performed according to the washing course selected by the user. That is, when the standard washing is selected, the rotating tub 30 rotates by receiving the rotational force of the driving motor 38 through the belt 37. Accordingly, the laundry in the rotary tub 30 is rolled up or pulled up by the lifter 32 to be washed. During the dehydration stroke, the laundry is dewatered by the high speed rotation of the rotary tub 30, and the dehydrated water is drained to the fixed tub 20 through the dehydration hole 31 and drained to the outside.
한편, 때가찌든 세탁물인 경우 사용자는 콘트롤부(60)를 조작하여 삶는 세탁행정을 수행하게 된다. 이러한 경우에는 고정조(20)에 소량의 세탁수가 일시적으로 유입되고 전기히터(50)가 구동되어 이를 가열시킴으로써, 고정조(20)의 바닥면에 있는 세탁수가 가열되어 증기를 발생 세탁물을 삶게 되어 세탁행정중 찌든때가 쉽게 빠진다. 이러한 전기히터(50)는 고정조(20) 전방측의 바닥면(21) 직상부공간에 가로방향으로 설치되어 있기 때문에, 구동모터(38)와 어긋나 이의 조립 및 아프터서비스를 용이하게 할 수 있으며, 전기히터(50)가 잠길 수 있는 최소량의 세탁수를 통해 삶는 기능을 수행할 수 있다.On the other hand, in the case of dirty laundry, the user operates the control unit 60 to perform a washing operation boiled. In this case, a small amount of washing water is temporarily introduced into the fixing tank 20 and the electric heater 50 is driven to heat it, so that the washing water on the bottom surface of the fixing tank 20 is heated to boil steam. It's easy to get rid of steam during the laundry administration. Since the electric heater 50 is installed in the transverse direction in the space immediately above the bottom surface 21 on the front side of the fixing tank 20, it can be displaced from the driving motor 38 and facilitates its assembly and after-sales service. , The electric heater 50 may perform a boil function through the minimum amount of washing water can be locked.
즉, 드럼세탁기의 삶는 세탁행정시 고정조(20)의 최하단에 위치된 전기히터(50)가 잠길 수 있는 정도의 세탁수만 공급함으로써, 적은 세탁수 활용이 가능하여 전기히터(50)의 구동시간을 줄일 수 있으며 전기히터(50)의 과열 현상을 방지할 수 있다. 실제로 본 발명자가 실험해 본 결과, 전기히터(50)를 이와 같이 설치한 상태에서는 대략 2ℓ정도의 세탁수를 고정조(20)에 급수하여도 드럼세탁기의 삶는 세탁을 충부히 수행시킬 수 있었다.That is, by supplying only the washing water that the electric heater 50 located at the bottom of the fixing tank 20 can be locked during the washing operation of the drum washing machine, a small amount of washing water can be utilized to drive the electric heater 50. It can reduce and prevent the overheating phenomenon of the electric heater (50). In fact, as a result of the inventors' experiment, the electric heater 50 was installed in this way, even if the washing water of approximately 2 L was supplied to the fixing tank 20, the washing of the drum washing machine could be sufficiently performed.
이상에서 상세히 설명한 바와 같이, 본 발명에 따른 드럼세탁기는 고정조와 회전조 사이의 공간에 전기히터가 설치되어 세탁물을 삶아빠는 행정시 고정조에 담수된 세탁수를 가열하는데, 전기히터를 고정조 바닥면의 직상부공간에 가로방향으로 설치함으로써, 전기히터가 잠길정도의 최소량의 세탁수 활용이 가능 전력소비를 줄일 수 있다. 또한 외부로 노출된 전기히터의 단자부에 일단부가 이와 접속되며 선단부에 피메일단자가 마련된 접속부재가 별도로 마련되어 있어서, 와이어하네스와의 전기접속을 용이하게 할 수 있다.As described in detail above, the drum washing machine according to the present invention is installed in the space between the fixed bath and the rotating bath to heat the wash water in the fixed bath during the stroke to wash the laundry, the electric heater to the bottom of the fixed bath By installing horizontally in the space directly above the surface, it is possible to utilize the minimum amount of wash water enough to lock the electric heater can reduce the power consumption. In addition, one end portion is connected to the terminal portion of the electric heater exposed to the outside and a connecting member provided with a female terminal at the front end is provided separately, thereby facilitating electrical connection with the wire harness.
