세탁기의 세탁물건조장치Laundry Dryer of Washing Machine

일반적으로 세탁물건조장치는 세탁물의 탈수가 완료된 후 고온의 열기를 세탁조내로 송풍시켜 주도록 하여 송풍되는 고온의 열기에 의해 세탁물이 건조될 수 있도록 하는 것으로서, 이러한, 종래의 건조장치는 외체와 세탁조를 연결시켜 주는 덕트의 후방에 외부의 공기를 흡입함과 아울러, 전방측으로 송풍시켜 주는 송풍팬이 구성되고, 상기 송풍팬의 전방에 외부로부터 송풍되는 차가운 공기를 고온의 열기로 열교환시켜 주는 열교환기로 구성되어 세탁물의 탈수가 완료되면 송풍팬과 열교환기에 전원을 인가시켜 주어 송풍팬에 의해 덕트내로 외부의 공기가 흡입된 뒤 전방측으로 송풍되고, 상기 송풍되는 공기는 송풍팬의 전방에 위치하고 있는 열교환기를 거치면서 고온의 열기로 열교환된 상태에서 세탁조내로 송풍되어 세탁물을 건조시켜 주게 되는 것이다.In general, the laundry drying apparatus is configured to blow high temperature heat into a washing tank after dehydration of the laundry is completed so that the laundry may be dried by blowing high temperature heat, and such a conventional drying apparatus connects the outer body and the washing tank. It is composed of a blower fan that sucks outside air at the rear of the duct to allow air to blow and blows it to the front side, and a heat exchanger that heat-exchanges cold air blown from the outside with high temperature heat in front of the blower fan. When the laundry is dewatered, power is supplied to the blower fan and the heat exchanger so that the outside air is sucked into the duct by the blower fan and blown to the front side, and the blown air passes through the heat exchanger located in front of the blower fan. Blow dry in the washing tank under heat exchange with high temperature heat. It will be.

상기와 같은 상태로 하여 고온의 열기를 지속적으로 송풍시켜 줄 경우 송풍되는 고온의 열기와 건조시 발생된 습기에 의해 건조효율이 떨어지는 경우가 발생되어 수시로 열교환기의 전원을 차단시켜 준 상태에서 외부의 차가운 공기가 세탁조내로 송풍되도록 하여 열기와 냉기에 의한 건조효율을 높여주게 되는데, 이때 덕트가 하나밖에 설치되지 않아 열교환되지 않는 차가운 공기도 항상 열교환기를 거친 뒤 세탁조내로 송풍이 이루어지도록 하고 있어 송풍팬에 의해 외부로부터 유입된 차가운 공기가 열교환기를 거치면서 일부의 공기가 손실되는 단점이 있고, 손실되지 않고 열교환기를 거친 공기만이 세탁조내로 송풍되도록 되어 있어 열교환기에 의한 공기의 손실에 따라 건조효율이 떨어지게 되는 등의 결함이 있었던 것이다.If the hot air is continuously blown in the above state, the drying efficiency decreases due to the hot air being blown and the moisture generated during drying, and the power of the heat exchanger is cut off from time to time. Cool air is blown into the washing tank to increase drying efficiency due to heat and cold. At this time, only one duct is installed so that cold air that is not heat exchanged is always passed through a heat exchanger and blown into the washing tank. Due to the disadvantage that the cold air introduced from the outside through the heat exchanger, some of the air is lost, and only the air passing through the heat exchanger is blown into the washing tank without being lost, resulting in a decrease in drying efficiency due to the loss of air by the heat exchanger. There was a defect.

본 고안은 세탁물의 건조행정시 송풍팬에 의해 외부로부터 유입되어 세탁조내로 송풍되는 열기와 냉기가 각각 송풍될 수 있도록 하는 각각의 송풍덕트를 설치하여 냉기가 송풍시 송풍되는 냉기의 손실이 없도록 하여 건조효율을 향상시켜 줄 수 있도록 하는 것으로서, 이는 세탁이 완료되면 외부의 공기를 강제 흡입함과 아울러, 송풍시켜 주면서 고온의 열기로 열교환시켜 준 열기에 의해 세탁물을 건조시켜 주는 건조장치에 있어서, 탑커어버의 내부 후방측에 외부로부터 흡입되는 공기가 행정상태에 따라 냉기와 열기가 각각의 덕트를 통해 송풍될 수 있도록 하는 냉·온기송풍수단이 갖추어진 것을 특징으로 하는 것이다.The present invention is installed by each blowing duct to allow the heat and cold air that is introduced from the outside by the blower fan to be blown into the washing tank during the drying administration of the laundry so that the cold air is blown when the air blown to dry In order to improve the efficiency, this is a drying apparatus for drying the laundry by the heat that is heat-exchanged by the hot air while blowing the air while forced to suck the outside air when the washing is completed, the top cover It is characterized in that the cold and hot air blowing means for allowing the air sucked from the outside on the inner rear side of the air to be blown through each duct according to the stroke state.

상기의 냉·온기송풍수단(400)의 수용부(410)내에 모터(420)의 구동에 의해 외부의 공기를 흡입하는 송풍팬(430)을 구성하고, 수용부의 상단부 양측으로 외부의 공기가 송풍될 수 있도록 하는 각각의 냉·온기덕트(440)(450)를 구성하며, 송풍팬에 의해 송풍되는 공기에 방향에 따라 이동되면서 냉·온기덕트를 교호로 차단시켜 주는 이동볼(460)을 구성하고 있으며, 온기덕트의 내부에 차가운 공기를 고온의 열기로 열교환시켜 주는 열교환기(470)로 구성하여 되는 것이다.In the accommodating part 410 of the cold / hot air blowing means 400, a blower fan 430 is formed to suck external air by driving the motor 420, and external air is blown to both sides of the upper end of the accommodating part. Each of the cold and warm air duct 440, 450 is configured to be made, and moving ball 460 to alternately block the cold and warm duct while moving along the direction to the air blown by the blowing fan. The heat exchanger 470 is configured to heat-exchange cold air into high-temperature heat inside the warm duct.

이때, 상기 각각의 냉·온기덕트 끝단부는 각각 세탁조내로 공기가 송풍될 수 있도록 설치한다.At this time, each end of the cold and warm air duct is installed so that air can be blown into the washing tank.

상기와 같은 구성으로 하는 본 고안의 작용을 설명하면 다음과 같다. 먼저, 세탁물의 세탁 및 탈수행정이 완료되면, 냉·온기송풍수단(400)이 가동되어 외부로부터 차가운 공기를 흡입시켜 고온의 열기와 차가운 공기를 저수조(500)내로 교호로 송풍시켜 주면서 탈수가 완료된 세탁물을 건조시켜 주게 된다.Referring to the operation of the present invention to the above configuration as follows. First, when the laundry washing and dehydration administration of the laundry is completed, the cold and hot air blowing means 400 is operated to suck cold air from the outside to blow hot and cold air alternately into the water reservoir 500 to complete dehydration. It will dry the laundry.

즉, 제2도의 (a)에서와 같이 모터(420)의 구동에 의해 송풍팬(430)이 시계방향으로 회전하게 되면 이의 회전력에 의해 외부로부터 유입되는 공기가 수용부(410)내에서 시계방향으로 회류되므로서, 이동볼(460)이 우측으로 이동되어 냉기덕트(440)를 밀폐시켜 주게되고, 이러한 상태에서 송풍팬에 의해 유입됨과 아울러, 회류되는 공기는 열려진 온기덕트(450)를 통해 송풍이 이루어지면서 상기 온기덕트의 내부에 설치되어 있는 열교환기(470)를 거치면서 열교환된 고온의 열기가 세탁조내로 송풍되어 세탁물을 건조시켜 주게 되는 것이며, 상기와 같이 고온의 열기에 의해 세탁물을 건조시켜 주게되면 건조시 온도변화에 의해 세탁조내에 습기가 차게되면, 모터(420)의 구동방향을 바꾸어주게 되면 이때부터 송풍팬(430)이 제2도의 (b)에서와 같이 반시계방향으로 회전하여 수용부(410)내에서 유입되는 공기가 좌측으로 회류시켜 주게 된다.That is, when the blowing fan 430 rotates clockwise by the driving of the motor 420 as shown in FIG. 2 (a), air introduced from the outside by the rotational force thereof is clockwise in the receiving portion 410. As it flows back, the moving ball 460 is moved to the right to seal the cold air duct 440, and in this state is introduced by the blower fan, the air flows through the open air duct 450 is blown This is done through the heat exchanger 470 is installed inside the warm duct is the heat of the high temperature heat is blown into the washing tank to dry the laundry, drying the laundry by high temperature heat as described above If the moisture is filled in the washing tank by the temperature change during drying, if the driving direction of the motor 420 is changed, the blower fan 430 rotates counterclockwise as shown in (b) of FIG. The air flowing in the receiving portion 410 flows to the left side.

상기와 같이 수용부내에서 일어나는 회류가 좌측으로 일어나게 되면 이의 회류력에 의해 냉기덕트(440)를 밀폐시켜 주고 있던 이동볼(460)이 좌측으로 이동되면서 온기덕트(450)를 밀폐시켜 주게되면 이동볼의 이동에 의해 열려진 냉기덕트(440)를 통해 회류되던 공기가 이송되는데, 이때 상기의 송풍덕트에는 열교환기가 없어 송풍덕트내로 송풍되는 차가운 공기의 손실이 없이 전량이 세탁조내로 송풍되므로서, 냉기에 의한 건조효율이 높아지게 되는 것이다.When the flow occurs in the receiving portion as described above occurs to the left side of the moving ball 460, which was sealing the cold air duct 440 by the flow of its flow is moved to the left to seal the warm duct 450, the moving ball The air that has flowed back through the cold air duct 440 opened by the movement of the air is transferred. At this time, the blower duct does not have a heat exchanger, and thus the entire air is blown into the washing tank without the loss of the cold air blown into the air duct. The drying efficiency will be increased.

이때, 열교환기는 전원이 차단되어 과열로 인한 손상을 방지하게 된다. 상기와 같이 모터(420)의 구동에 의해 회전되는 송풍팬(430)이 건조행정도중 좌·우교호로 회전되면서 고온의 열기와 차가운 공기를 송풍시켜 주면서 세탁물을 건조시켜 주게 되는 것이다.At this time, the heat exchanger is cut off the power to prevent damage due to overheating. As described above, the blowing fan 430 rotated by the driving of the motor 420 rotates to the left and right sides of the drying process while drying the laundry while blowing hot heat and cold air.

본 고안은 세탁물의 건조행정시 외부로부터 공기를 강제 흡입 및 송풍시켜 주는 송풍팬을 정·역회전시켜 주면서 고온의 열기를 송풍시켜 줄 경우 열교환기를 거쳐 열교환된 고온의 열기에 의해 건조가 이루어지도록 하고, 냉기를 송풍시켜 줄 경우에는 열교환기를 거치지 않고 송풍이 되도록 하여 열교환기에 의한 풍량의 손실이 없이 송풍되는 공기의 전량이 송풍되어 냉기에 의한 건조효율이 높아질 수 있게 되는 효과가 있는 것이다.The present invention is to dry by the high temperature heat exchanged through the heat exchanger in the case of blowing the high temperature heat while forward and reverse rotation of the blowing fan forcibly suctioning and blowing air from the outside during the drying operation of the laundry. In the case of cooling the cold air, the air is blown without passing through the heat exchanger, so that the entire amount of air to be blown is blown without loss of air volume by the heat exchanger, thereby increasing drying efficiency due to cold air.

본 고안은 세탁기의 세탁물건조장치에 관한 것으로, 특히 세탁물을 건조시 열기와 냉기가 효율적으로 송풍되도록 하여 세탁물의 건조효율을 향상시켜 줄 수 있도록 한 세탁기의 세탁물건조장치에 관한 것이다.The present invention relates to a laundry drying apparatus of a washing machine, and more particularly, to a laundry drying apparatus of a washing machine to improve the drying efficiency of the laundry by allowing the heat and cold air to be efficiently blown during drying.
