이와같이 구성된 상태에서 가열기(3)에 의해 가열된 뜨거운 공기가 송풍팬(1)에 의해 강제 순환되어 드럼내부로 유입되면서 드럼내부에 있는 세탁물을 가열하여 수분을 증발시키고 순환유도관(2)에서 찬물과 부딪히면서 응축이 일어나 공기중의 습기가 제거되어 건조가 수행된다.In this state, the hot air heated by the heater 3 is forcibly circulated by the blowing fan 1 and flows into the drum, thereby heating the laundry in the drum to evaporate water, So that condensation occurs and moisture in the air is removed and drying is performed.
이러한 건조과정을 수행하기 위해 종래 드럼세기는 건조 개시점에 가열기(3)와 송풍팬(1)이 작동하여 내부를 가열하는 공기가 순환되고, 이때 응축수가 공급되어 건조가 완료되는 시점까지 계속 응축수가 공급되게 된다.In order to perform such a drying process, the conventional drum strength is such that the heater 3 and the blowing fan 1 operate at the starting point of drying to circulate air heating the inside of the drum. At this time, the condensed water is supplied, .
그러나 이러한 종래 건조방법은 가열된 공기가 드럼내부에 있는 세탁물을 가열하여 세탁물에 있는 수분을 증발시키기 전에 응축수가 계속 공급되어 내부 뜨거운 공기를 식히면서 실제 응축은 일어나지 않으므로 물 및 전력을 낭비하게 되는 문제점이 있었다.However, in the conventional drying method, since the heated air is heated by the laundry in the drum to continuously supply the condensed water before the moisture in the laundry is evaporated, the internal hot air is cooled and the condensation does not actually occur, there was.
본 발명은 상기한 바와같은 종래의 문제점을 해결하기 위하여 발명된 것으로서, 세탁기의 건조시 응축수 공급시기를 외조내에 있는 세탁물의 온도에 따라 급수를 제어하여, 세탁물의 건조성능을 높이고 세탁기의 효율을 향상시키도록 하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide an apparatus and a method for controlling the supply of condensed water during the drying of a washing machine, The purpose of the

본 발명을 첨부도면을 참조하여 이하에서 상세히 설명한다.The present invention is described in detail below with reference to the accompanying drawings.
먼저 본 발명이 적용되는 드럼세탁기의 구성을 제2도를 통해 살펴보면 외조(100)상부에 건조유도관(102)이 장착되고, 상기 건조유도관(102)내에는 세탁물을 가열하기 위한 가열기(101)와 가열기(101)에 의해 가열된 뜨거운 공기를 드럼(105)내부로 불어넣기 위한 송풍팬(103) 그리고 온도감지를 위한 제1온도감지기(107)가 설치되며, 상기 드럼(105)내의 습한 공기가 송풍팬(103)에 의해 순환되는 응축유도관(106)이 설치된다.Referring to FIG. 2, a drying induction pipe 102 is mounted on an outer tub 100, and a heater 101 for heating laundry is installed in the drying induction pipe 102. A blowing fan 103 for blowing the hot air heated by the heater 101 into the drum 105 and a first temperature sensor 107 for detecting the temperature are installed in the drum 105, And a condensation induction pipe 106 through which the air is circulated by the air blowing fan 103 is installed.
그리고 상기 외조(100)내에는 내부의 온도를 인식하기 위해 제2온도감지기(107')가 설치되며, 풀리(109)는 모터(104)의 동력을 전달받아 드럼(105)을 회전시키는 역할을 한다.A second temperature sensor 107 'is installed in the outer tub 100 to recognize the temperature of the drum 105. The pulley 109 receives the power of the motor 104 and rotates the drum 105 do.
도면중 미설명 부호 108은 배수호스를 나타낸다.In the drawing, reference numeral 108 denotes a drain hose.
이와같이 구성되는 본 발명의 세탁기는 모터(104)의 동력에 의해 좌우 반전되는 드럼(105)의 내부에 있는 세탁물은 건조유도관(102)을 지난 뜨거운 공기가 드럼(105)의 내부로 유입되면서 가열되어 수분을 증발시키며 수분을 함유한 습한 공기는 응축유도관(106)을 지나 송풍팬(103)으로 빨려 들어가 순환을 하면서 건조과정을 수행한다.In the washing machine of the present invention configured as described above, the laundry in the drum 105, which is reversed leftward and rightward by the power of the motor 104, is heated by the hot air passing through the drying induction pipe 102 into the drum 105 And the moist air containing moisture is sucked into the air blowing fan 103 through the condensation induction pipe 106 to perform the drying process while circulating.
세탁물에서 증발된 수분을 제거하기 위하여 습한 공기가 응축유도관(106)을 지나가는 동안 외부에서 찬물(응축수)을 공급하는데, 수분을 함유한 뜨거운 공기는 찬물과 부딪히면서 이슬점에 도달하게 되어 공기중의 수분은 물방울로 변해 응축수와 함께 배수호스(108)를 통해 밖으로 빠져나간다.In order to remove the evaporated water from the laundry, moist air is supplied from the outside while passing through the condensation induction pipe 106. Hot air containing moisture reaches the dew point while bumping against cold water, Is turned into a water droplet and flows out through the drain hose 108 together with the condensed water.
그리고 응축수에 의해 제습된 공기는 다시 송풍팬(103)을 지나 가열기(101)에 의해 가열되어 드럼(105) 내부의 세탁물을 건조시키게 된다.The air dehumidified by the condensed water is again heated by the heater 101 through the blowing fan 103 to dry the laundry in the drum 105.
이러한 건조를 수행함에 있어 가열기(15)의 이상발열과 세탁물이 들어있는 드럼(105) 내부의 온도를 제어하기 위해 온도감지기가 장착되었고, 가열기(101)의 가열 및 옷감의 손상만을 고려하여 이상 과열만을 온도감지기가 감지하여 가열기(101)를 제어하기 위한 방법으로 사용되었다.In this drying, a temperature sensor is installed to control the abnormal heat of the heater 15 and the temperature of the inside of the drum 105 containing the laundry. In consideration of heating of the heater 101 and damage of the cloth, Is used as a method for controlling the heater 101 by detecting only the temperature sensor.
본 발명은 제3도의 건조특성곡선을 이용하여 세탁물의 초기 가열시 내부 온도 상승시간동안 수분의 증발량이 없기 때문에 온도감지기의 온도를 감지하여 응축수 공급을 제어하도록 한 것이다.The present invention uses the drying characteristic curve of FIG. 3 to control the supply of condensed water by sensing the temperature of the temperature sensor since there is no evaporation of moisture during the internal temperature rise time during the initial heating of the laundry.
즉, 초기 건조를 수행함에 있어서 가열기(101)에서 가열된 공기가 드럼(105) 내부에 유입되어 세탁물을 가열하고 응축유도관(106)으로 빠져나가기 전의 외조(100) 내부 온도를 제2온도감지기(107')에서 인식하여 제4도에 나타난 바와 같이 내부 세탁물이 가열되어 증발이 활발히 일어나는 일정온도 T에 도달할 때부터 응축수를 공급한다. 급수와 관려된 배수방법은 건조기능이 수행되는 초기에 외조(100) 내부의 물을 제거하기 위해 일정시간 작동하다가 멈추며 외조(100)의 내부온도가 일정온도에 도달하여 응축수가 공급되는 순간부터 다시 배수펌프를 작동시켜 배수를 행한다.That is, in the initial drying, the internal temperature of the outer tank 100 before the air heated by the heater 101 flows into the drum 105 and the laundry is heated and escapes to the condensation induction pipe 106, As shown in FIG. 4, the condensing water is supplied from the time when the internal laundry is heated and reaches a predetermined temperature T at which evaporation actively occurs. The drainage method related to the water supply is operated for a certain period of time to remove the water in the outer tank 100 at the initial stage of performing the drying function and is stopped again from the moment when the inner temperature of the outer tank 100 reaches a predetermined temperature and the condensed water is supplied Drainage pump is operated to drain water.
이후 건조가 완료되는 시점까지 건조가열기(101)와 송풍팬(103), 배수펌프를 계속 작동시키면서 응축수의 공급을 계속하여 세탁물의 건조를 완료하게 되는 것이다.Then, the drying of the laundry is continued by continuing the supply of the condensed water while continuing to operate the drying oven 101, the blowing fan 103, and the drain pump until the drying is completed.
상기 전체적인 제어과정은 제5도에 나타내었다.The overall control procedure is shown in FIG.
이상에서 설명한 바와같이 본 발명의 건조방법은 세탁물이 가열기에 의해 가열되어 증기가 발생하는 시점에 응축수를 공급하므로 증발을 일으키기 위한 분위기 온도를 높이는 순간까지의 순환되는 공기가 응축수와 부딪히면서 발생하는 열손실을 막아 빠른 시간내에 세탁물이 가열되게 하여 건조성능을 높이고 제품의 이용효율을 향상시킬 수 있는 효과가 있다.As described above, in the drying method of the present invention, since the laundry is heated by the heater and the condensed water is supplied at the time when the steam is generated, the heat loss due to the circulation of the air until the ambient temperature, So that the laundry is heated in a short period of time, thereby enhancing the drying performance and improving the utilization efficiency of the product.
본 발명은 드럼세탁기의 건조방법에 관한 것으로서, 특히 세탁물 건조시 응축수 공급시기를 제어하여 건조 개시점부터 공급하는 응축수를 절약하고 가열기에 의해 발열되는 열이 세탁물을 빨리 가열하도록 하여 건조성능을 향상시키도록 하기 위한 세탁물의 건조방법에 관한 것이다.In particular, the present invention relates to a drying method of a drum type washing machine, and more particularly, to a drying method of a drum type washing machine, in particular, a method of controlling a supply time of condensed water during drying of a laundry to save condensate water supplied from a drying point, To a method for drying laundry.
