Description
일반적인 드럼세탁기는 제 1 도에 도시된 바와같이 공기를 가열하는 히터(3)와, 상기 히터(3)에 의해 가열된 공기를 드럼내부로 유입시키는 송풍팬(1)과, 상기 유압된 공기를 응축시키는 순환덕트(2)와, 상기 순환덕트(2)로 응축수를 공급하는 응축수 공급호스(5)로 구성된다.A general drum washing machine includes a heater (3) for heating air as shown in FIG. 1, a blowing fan (1) for introducing air heated by the heater (3) into the drum, and the hydraulic air. It consists of a circulation duct (2) for condensation, and a condensate water supply hose (5) for supplying condensate to the circulation duct (2).
도면중 미설명 부호 4 는 터브를 나타낸다.In the drawings, reference numeral 4 denotes a tub.
이와같이 구성된 상태에서 히터(3)에 의해 가열된 뜨거운 공기가 송풍팬(1)에 의개 강제 순환하여 드럼내부로 유입되면서 드럼내부에 있는 세탁물을 가열하여 수분을 증발시키고 순환덕트(2)에서 찬물과 부딧히면서 응축이 일어나 공기중의 습기가 제거되어 건조가 수행된다.In such a configuration, hot air heated by the heater 3 is forced into the blower fan 1 and flows into the drum, thereby heating the laundry in the drum to evaporate moisture and cooling water from the circulation duct 2. Condensation occurs as a result of condensation, and moisture in the air is removed to carry out drying.
이러한 건조과정을 수행하기 위해 종래 드럼세탁기는 건조 개시점에 히터(3)와 송풍팬(1)이 작동하여 내부를 가열하는 공기가 순환되고, 이때 응축수가 공급되어 건조가 완료되는 시점까지 계속 응축수가 공급되게 된다.In order to perform the drying process, the conventional drum washing machine operates the heater 3 and the blower fan 1 at the start of drying to circulate air for heating the inside of the drum washing machine. At this time, the condensed water continues to be supplied until the drying is completed. Will be supplied.
그러나 이러한 종래 건조방법은 가열된 공기가 드럼내부에 있는 세탁물을 가열하여 세탁물에 있는 수분을 증발시키기 전에 응축수가 계속 공급 되어 내부 뜨거운 공기를 식히면서 실제 응축은 일어나지 않으므로 물 및 전력을 낭비하게 되는 문제점이 있었다.However, this conventional drying method is a problem that wastes water and power because the condensed water is continuously supplied before the heated air to heat the laundry inside the drum to evaporate the moisture in the laundry to cool the internal hot air does not occur. there was.
본 발명은 상기한 바와같은 종래의 문제점을 해결하기 위하여 발명된 것으로서, 세탁기의 건조시 응축수 공급시기를 터브내에 있는 세탁물의 온도에 따라 급수를 제어하여, 센탁물의 건조성능을 높이고 세탁기의 효율을 향상시키도록 하는데 목적이 있다.The present invention has been invented to solve the conventional problems as described above, by controlling the water supply according to the temperature of the laundry in the tub during the drying of the washing machine, to increase the drying performance and improve the efficiency of the washing machine The purpose is to make it work.

본 발명은 첨부도면을 참조하여 이하에서 상세히 설명한다.The present invention will be described in detail below with reference to the accompanying drawings.
먼저 본 발명이 적용되는 드럼세탁기의 구성을 제 2 도를 통해 살펴보면 터브(100)상부에 건조덕트(102)가 장착되고, 상기 건조덕트(102)내에는 세탁물을 가열하기 위한 히터(101)와 히터(101)에 의해 가열된 뜨거운 공기를 드럼(105) 내부로 불어넣기 위한 송풍팬(103) 그리고 온도감지를 위한 제1서미스터(107)가 설치되며, 상기 드럼(105)내에 습한 공기가 송풍팬(103)에 의해 순환되는 응축덕트(106)가 설치된다.First, the construction of the drum washing machine to which the present invention is applied is shown in FIG. 2 through a drying duct 102 on the tub 100, and a heater 101 for heating laundry in the drying duct 102. A blowing fan 103 for blowing hot air heated by the heater 101 into the drum 105 and a first thermistor 107 for temperature sensing are installed, and humid air is blown in the drum 105. The condensation duct 106 circulated by the fan 103 is installed.
그리고 상기 터브(100)내에는 내부의 온도를 인식하기 위해 제2서미스터(107')가 설치되며, 풀리(109)는 모터(104)의 동력을 전달받아 드럼(105)을 회전시키는 역할을 한다.In addition, a second thermistor 107 ′ is installed in the tub 100 to recognize an internal temperature, and the pulley 109 serves to rotate the drum 105 by receiving power from the motor 104. .
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 건조덕트(102)를 지난 뜨거운 공기가 드럼(105)의 내부로 유입되면서 가열되어 수분을 증발 시키면 수분을 함유한 습한 공기는 응축덕트(106)를 지나 송풍팬(103)으로 빨려 들어가 순환을 하면서 건조과정을 수행한다.In the washing machine of the present invention configured as described above, the laundry inside the drum 105 which is inverted by the power of the motor 104 is heated while the hot air passing through the drying duct 102 flows into the drum 105. When the moisture is evaporated, the humid air containing the moisture is sucked into the blowing fan 103 through the condensation duct 106 and circulated to perform a drying process.
세탁물에서 증발된 수분을 제거하기 위하여 습한공기가 응축덕트(106)를 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.To remove the water evaporated from the laundry, cold air (condensed water) is supplied from the outside while the humid air passes through the condensation duct 106. The hot air containing moisture hits the cold water and reaches the dew point, so that the moisture in the air It turns into droplets and exits through the drain hose 108 with condensate.
그리고 응축수에 의해 제습된 공기는 다시 송풍팬(103)을 지나 히터(101)에 의해 가열되어 드럼(105) 내부의 세탁물을 건조시키게 된다.In addition, the air dehumidified by the condensed water passes through the blower fan 103 and is heated by the heater 101 to dry the laundry inside the drum 105.
이러한 건조를 수행함에 있어 히터(15)의 이상발열과 세탁물이 들어있는 드럼(105)내부의 온도를 제어하기 위해 서미스터가 장착되었고, 히터(101)의 가열 및 옷감의 손상만을 고려하여 이상 과열만을 서미스터가 감지하여 히터(101)를 제어하기 위한 방법으로 사용되었다.In performing such drying, a thermistor is mounted to control abnormal heating of the heater 15 and temperature inside the drum 105 in which the laundry is contained, and only the abnormal overheating is considered in consideration of heating of the heater 101 and damage to the cloth. The thermistor was used as a method for sensing and controlling the heater 101.
본 발명은 제 3 도의 건조특성곡선을 이용하여 세탁물의 초기 가열시 내부 온도 상승시간동안 수분의 증발량이 없기 때문에 서미스터의 온도를 감지하여 응축수 공급을 제어하도록 한 것이다.The present invention is to control the supply of condensate by sensing the temperature of the thermistor because there is no evaporation of moisture during the internal temperature rise time during the initial heating of the laundry by using the drying characteristic curve of FIG.
즉, 초기 건조를 수행함에 있어서 히터(101)에서 가열된 공기가 드럼(105) 내부에 유입되어 세탁물을 가열하고 응축덕트(106)로 빠져나가기 전의 터브(100) 내부 온도를 제2서미스터(107')에서 인식하여 제 4 도에 나타난 바와같이 내부 세탁물이 가열되어 증발이 활발히 일어나는 일정온도 T 에 도달할 때부터 응축수를 공급한다. 급수와 관련된 배수방법은 건조기능이 수행되는 초기의 터브(100) 내부의 물을 제거하기 위해 일정시간 작동하다가 멈추며 터브(100)의 내부온도가 일정온도에 달하여 응축수가 공급되는 순간부터 다시 배수펌프를 작동시켜 배수를 행한다.That is, in performing the initial drying, the air heated in the heater 101 flows into the drum 105 to heat the laundry and exit the internal temperature of the tub 100 before exiting to the condensation duct 106. As shown in Fig. 4, condensed water is supplied from the time when the internal laundry is heated to reach a constant temperature T at which evaporation is active. The drainage method related to the water supply is stopped for a certain time to remove the water in the tub 100 at the beginning of the drying function, and the drain pump is pumped again from the moment condensed water is supplied because the internal temperature of the tub 100 reaches a certain temperature. Drain by draining.
이후 건조가 완료되는 시점까지 건조히터(101)와 송풍팬(103), 배수펌프를 계속작동시키면서 응축수의 공급을 계속하여 세탁물의 건조를 완료하게 되는 것이다.After that, the drying heater 101, the blowing fan 103, and the drainage pump continue to supply the condensed water until the drying is completed, thereby completing the drying of the laundry.
상기 전체적인 제어과정은 제 5 도에 나타내었다.The overall control process is shown in FIG.
이상에서 설명한 바와같이 본 발명의 건조방법은 세탁물이 히터에 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, the laundry is heated by a heater to supply condensed water when steam is generated, and thus heat loss generated when the circulated air hits the condensed water until the atmospheric temperature for evaporation is raised. By preventing the laundry to be heated in a short time to increase the drying performance and the effect of using the product can be improved.
본 발명은 드럼세탁기의 건조방법에 관한 것으로서, 특히 세탁물 건조시 응축수 공급시기를 제어하여 건조 개시점부터 공급하는 응축수를 절약하고 히터에 의해 발열되는 열이 세탁물을 빨리 가열하도록 하여 건조성능을 향상시키도록 하기위한 세탁물의 건조방법에 관한 것이다.The present invention relates to a drying method of a drum washing machine, and in particular, to control the condensed water supply timing when drying the laundry, to save condensate supplied from the start of drying, and to heat the laundry quickly by heat generated by the heater to improve the drying performance. It relates to a method of drying laundry.
