Description

드럼 세탁기{DRUM TYPE WASHING MACHINE}Drum Washing Machine {DRUM TYPE WASHING MACHINE}

본 발명은 드럼 세탁기에 관한 것으로, 상세하게는 드럼 세탁기의 응축기에 습도를 측정할 수 있는 수단을 설치하여 세탁기의 건조 성능을 향상시킬 수 있는 드럼 세탁기에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a drum washing machine that can improve the drying performance of the washing machine by installing a means for measuring the humidity in the condenser of the drum washing machine.

일반적으로 드럼 세탁기는 원통형상의 드럼을 세탁조 내부로부터 회전시키는 한편, 이와 같은 과정에서 세탁물을 드럼 상부로부터 하부로 낙하시킴으로써 세탁이 이루어지도록 구성한 것이다.In general, the drum washing machine is configured to rotate the cylindrical drum from the inside of the washing tank, while washing is carried out by dropping the laundry from the drum top to the bottom in this process.

이와 같은 드럼방식의 세탁기는 세탁물의 꼬임에 의한 손상이 펄세이터 방식의 세탁기나 에지테이터 방식의 세탁기에 비해 상대적으로 적으며, 이와 함께 세탁수의 사용량이 펄세이터 방식의 세탁기나 에지테이터 방식의 세탁기에 비해 상대적으로 적다는 등의 특성을 갖는다.The drum type washing machine has less damage due to the twisting of the laundry than the pulsator type washing machine or the edge data type washing machine. It is relatively small compared with.

이와 같은 드럼방식의 세탁기는 도 3에 도시된 바와 같이, 가상선으로 도시한 외상(110)의 내부로부터 수평으로 저수조(111)가 설치되며, 그 내부에는 세탁조의 기능을 갖는 드럼(112)이 회전가능하게 설치되며, 저수조(111)의 하부에는 상기한 드럼(111)을 회전시키는 구동모터(113)등이 설치된다.As shown in FIG. 3, the drum type washing machine has a water storage tank 111 installed horizontally from the inside of the trauma 110 shown as a virtual line, and a drum 112 having a function of a washing tank is provided therein. It is rotatably installed, the lower portion of the reservoir 111, the drive motor 113 for rotating the drum 111 is installed.

이와 함께 저수조(111)의 상부에는 외부로부터 세탁수가 공급되는 급수구(114)가 구비되며, 상기한 급수구(114)의 일부는 세제통(115)을 경유하여 저수조(111) 내부로 공급되도록 한다.In addition, the upper portion of the reservoir 111 is provided with a water supply port 114 for supplying wash water from the outside, and a portion of the water supply port 114 is supplied to the inside of the water reservoir 111 via the detergent container 115. .

또한, 저수조(111)의 하단으로는 세탁수가 배출되도록 여과기(116) 및 배수펌프(117)와 배수호스(118)가 각각 연결되며, 드럼(112)의 정면으로는 도어(119)가 설치되어 있다.In addition, a filter 116, a drain pump 117, and a drain hose 118 are respectively connected to the lower end of the water storage tank 111, and a door 119 is installed at the front of the drum 112. have.

상기한 바와 같은 구조를 갖는 드럼 세탁기(100)는 통상적으로 건조기능을 구비함으로써 세탁 및 탈수행정의 반복에 따른 세탁의 종료후 히터와 송풍팬의 동작에 따라 드럼(112) 내부로 열풍을 분사하여 세탁물을 건조시키도록 한다.Drum washing machine 100 having a structure as described above is typically provided with a drying function to spray hot air into the drum 112 in accordance with the operation of the heater and the blower fan after the end of the washing according to the repeated washing and dehydration administration Allow the laundry to dry.

도 4는 상기한 바와 같은 드럼 세탁기의 상부에 결합되어 세탁의 종료후 세탁물을 건조시키는 건조장치(160) 및 상기한 건조장치(160)의 일측에 결합되어 공기중의 습기를 응축시키는 응축기(150)를 도시한 도면으로서, 상기한 건조장치(160)는 저수조의 배면 상부 및 도어의 내측 상부를 연결시킨 덕트(151)의 일측에 송풍팬(153)을 결합시키고, 도어의 내측 상부와 연결된 토출구(152) 및 상기 송풍팬(153) 사이의 내부공간으로는 전열히터(154)가 설치된 구조를 갖는다.4 is a condenser 150 coupled to the upper portion of the drum washing machine as described above and coupled to one side of the drying device 160 to dry the laundry after the end of washing and condensing moisture in the air. ), The drying device 160 is coupled to the blower fan 153 to one side of the duct 151 connecting the rear top of the reservoir and the inner upper portion of the door, the discharge port connected to the inner upper portion of the door An inner space between the 152 and the blowing fan 153 has a structure in which an electric heater 154 is installed.

그리고, 토출구(152) 부위에는 전열히터(154)에 의해 발열된 온도를 감지할 수 있는 온도감지센서(156)가 설치되어 있다.In addition, a temperature detection sensor 156 that detects a temperature generated by the heat transfer heater 154 is installed at the discharge port 152.

상기한 건조장치(160)는 세탁종료후 전열히터(154)의 발열과 함께 송풍팬(153)의 동작에 따라 고온의 공기를 드럼 내부로 분사시키는 한편, 드럼의 내부공기를 강제 순환시킴으로써 세탁물을 건조시킨다.The drying apparatus 160 injects high temperature air into the drum according to the operation of the blower fan 153 together with the heat generation of the heat transfer heater 154 after the end of the washing, and circulates the laundry by forcibly circulating the internal air of the drum. To dry.

한편, 상기한 세탁물의 건조과정에서는 공기중의 습기를 제거해야 원활한 건조가 가능하므로 통상적으로 건조장치(160)의 송풍팬(153)과 저수조 사이에 응축기(150)를 개재시킨다.On the other hand, in the drying process of the laundry to remove the moisture in the air can be smoothly dried, the condenser 150 is usually interposed between the blower fan 153 and the water tank of the drying apparatus 160.

상기한 응축기(150)는 상부에 연결된 급수관(120)을 통해 공급받은 상온의 세탁수를 응축 덕트(170)의 벽면으로 흘려 보내 응축 덕트(170) 내부의 고온 다습한 공기를 상대적으로 낮은 온도를 갖는 세탁수와 접촉시킴으로써 수증기를 응축시키는 한편, 이에 따라 드럼 내부의 수증기를 제거한다.The condenser 150 flows the wash water at room temperature supplied through the water supply pipe 120 connected to the upper portion to the wall surface of the condensation duct 170 to provide a relatively low temperature to the high temperature and humid air inside the condensation duct 170. The water vapor is condensed by contacting the washing water having the same, thereby removing the water vapor inside the drum.

그러나, 이와 같은 종래 드럼 세탁기는 건조과정에서 전열히터(154)에 의해 발열된 온도를 온도감지센서(156)에 의해 감지할 뿐 습도를 측정할 수 있는 수단이 없어 건조성능이 저하되는 문제점이 있었다.However, such a conventional drum washing machine has a problem in that drying performance is deteriorated because there is no means for measuring humidity generated by the heat transfer heater 154 by the temperature sensor 156 in the drying process. .

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 안출된 것으로, 본 발명의 기술적 과제는 드럼 세탁기의 응축기에 습도를 측정할 수 있는 수단을 설치하여 세탁기의 건조 성능을 향상시킬 수 있는 드럼 세탁기를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, the technical problem of the present invention is to install a means for measuring the humidity in the condenser of the drum washing machine drum washing machine that can improve the drying performance of the washing machine To provide.

여기서, 응축 덕트(61)를 통과한 공기는 응축 덕트(61)의 상부에 연결된 급수관(80)을 통해 공급받은 상온의 세탁수를 응축 덕트(61)의 벽면으로 흘려 보내 응축 덕트(61) 내부의 고온 다습한 공기를 상대적으로 낮은 온도를 갖는 세탁수와 접촉시킴으로써 수증기를 응축시키고, 응축 덕트(61)의 벽면으로 흐르는 세탁수는 받이홈부(63)에 고이게 되어 이 받이홈부(63)에 설치된 습구온도센서(67)의 습도계에 뒤덮인 헝겊을 적시게 된다.Here, the air passing through the condensation duct 61 flows the washing water at room temperature supplied through the water supply pipe 80 connected to the upper portion of the condensation duct 61 to the wall surface of the condensation duct 61, so as to be inside the condensation duct 61. Condensed water vapor by contacting the hot and humid air of the contact with the washing water having a relatively low temperature, the washing water flowing to the wall surface of the condensation duct 61 is accumulated in the receiving groove (63) is installed in the receiving groove (63) Wet the cloth covered in the hygrometer of the wet bulb temperature sensor (67).

이와 같이 다량의 습기가 함유된 드럼 내부의 공기가 응축 덕트(61)를 통과할 때 건구온도센서(67)와 습구온도센서(65)에 의해 건구온도와 습구온도가 측정되고 이 측정에 의해 습도를 측정할 수 있다.When the air in the drum containing a large amount of moisture passes through the condensation duct 61, the dry bulb temperature and the wet bulb temperature are measured by the dry bulb temperature sensor 67 and the wet bulb temperature sensor 65. Can be measured.

이상에서 상세히 설명한 바와 같이 본 발명 드럼 세탁기에 따르면, 드럼 세탁기의 응축기에 습구온도센서와 건구온도센서를 설치한 구성으로, 본 발명에 의하면, 습구온도센서와 건구온도센서에 의해 드럼 세탁기의 건조과정에서 발생되는 습도를 정확하게 측정할 수 있어 드럼 세탁기의 건조 성능 뿐만 아니라 제품의 이용효율을 향상시킬 수 있는 등의 효과가 있다.As described in detail above, according to the drum washing machine of the present invention, a wet bulb temperature sensor and a dry bulb temperature sensor are installed in the condenser of the drum washing machine. According to the present invention, a drying process of the drum washing machine is performed by the wet bulb temperature sensor and the dry bulb temperature sensor. Humidity can be measured accurately from the drying performance of the drum washing machine, as well as the efficiency of the product can be improved.
