It relates to a dry washing machine and a control method thereof to shorten the time.
일반적으로 건조 세탁기는 통상적인 세탁, 헹굼, 탈수과정을 종료한 후 열풍에 의해 세탁물의 건조까지 수행할 수 있도록 한 것이며, 그 구조는 제1도에 도시된 바와 같이 열풍을 세탁조(21)내로 공급하는 히터(13)가 상부 일측에 설치되고, 이의 한 측면에 열풍을 강제 송풍하는 송풍팬(14)가 설치된 열풍공급장치를 구비하고 있으며, 상기 세탁기 하부 소정위치에는 열풍을 외부로 배출하는 배기밸브(24)가 설치되며, 세탁조(21) 하부에는 세탁물을 뒤집어주는 펄세이터(23)가 위치하고, 상기 펄세이터(23)는 샤프트(26)에 의해 모터(10)와 연결되어 있다.In general, the washing machine is to dry the laundry by the hot air after the normal washing, rinsing, dehydration process is completed, the structure is supplied to the washing tank 21 hot air as shown in FIG. The heater 13 is provided on one side of the upper side, and has a hot air supply device is provided with a blowing fan 14 for forcibly blowing hot air on one side thereof, the exhaust valve for discharging the hot air to the outside at a predetermined position of the lower part of the washing machine A 24 is installed, and a pulsator 23 is disposed below the washing tank 21 to turn over the laundry. The pulsator 23 is connected to the motor 10 by a shaft 26.
또한 세탁조(21) 외부로 형성된 수조(22) 일측 중앙부에는 온도를 감지하는 온도감지수단(3)이 설치되고, 상기 수조(22) 하부 일측에는 세탁물의 량을 감지하는 무게감지수단(6)이 각각 설치된다.In addition, a temperature sensing means 3 for sensing a temperature is installed at a central portion of one side of the water tank 22 formed outside the washing tank 21, and a weight sensing means 6 for sensing an amount of laundry on the lower side of the water tank 22 is provided.

이와 같이 이루어진 본 발명을 제2도 내지 제3도에 의해 건조과정을 설명하면, 먼저 운전조작수단(2)에 의해 통상적인 세탁, 헹굼, 탈수과정을 종료한 후 건조모드로 들어가면 마이콤(7)에서 세탁물의 건조과정을 실행하기 위해 히터(13)를 가열하여 열풍을 세탁조(21) 내부로 공급하게 되며, 이때 마이콤(7)에서는 무게감지수단(6)으로부터 출력되는 데이타를 판독하여 건조대상의 세탁물 양을 감지하여 건조시간을 설정하고, 고른 건조를 위해 모터(10)를 제어하여 펄세이터(23)를 간헐적으로 회전시킴으로서 세탁물을 뒤집는 과정을 반복하게 된다.Referring to the drying process according to the present invention made as described above with reference to FIGS. 2 to 3, first, after the usual washing, rinsing, and dehydration processes are completed by the operation operation means 2, the microcomputer 7 enters the drying mode. In order to perform the drying process of the laundry in the heater 13 is heated to supply the hot air into the washing tank 21, wherein the microcomputer (7) reads the data output from the weight sensing means (6) of the drying target By detecting the amount of laundry to set the drying time, by controlling the motor 10 for even drying to rotate the pulsator 23 intermittently to repeat the process of inverting the laundry.
또한 마이콤(7)은 온도감지수단(3)과 습도감지수단(4)으로 부터 출력되는 데이타를 읽어들여 현재 세탁조(21) 내부온도와 습도를 파악한 후 세탁물의 양과 세탁조(21)내의 온도 및 습도를 비교연산하여 세탁조내의 건조조건을 최적으로 유지함과 동시에 세탁조(21) 내의 온도 및 습도가 과도하게 높을 경우 송풍팬인 열풍배출수단(11)을 구동하여 세탁조(21) 내부의 온도와 습도를 낮추게 되며, 이때 2방향밸브(12)의 제어는 배수 또는 탈수과정에서 배수호스(12b)로 유로를 형성하고, 건조과정에서는 열풍배기호스(12a)로 배기로를 형성시키게 된다.In addition, the microcomputer 7 reads the data output from the temperature sensing means 3 and the humidity sensing means 4 to determine the current temperature and humidity of the washing tank 21, and then the amount of laundry and the temperature and humidity of the washing tank 21. Compared to maintain optimal drying conditions in the washing tank and at the same time excessively high temperature and humidity in the washing tank 21 to drive the hot air discharge means (11) blowing fan to lower the temperature and humidity inside the washing tank 21 In this case, the control of the two-way valve 12 forms a flow path to the drain hose 12b in the drainage or dewatering process, and forms an exhaust path to the hot air exhaust hose 12a in the drying process.
한편 마이콤 내부에는 제4도와 같이 세탁조 내부의 온도, 습도, 세탁물의 양에 따라 최적의 건조조건을 유지할 수 있도록 데이타가 내장되어 있다.On the other hand, inside the microcomputer, as shown in FIG. 4, data is embedded to maintain optimal drying conditions according to temperature, humidity, and amount of laundry in the washing tank.
즉 제4도(a)는 세탁조 내의 온도가 상승될수록 건조효율이 높아짐을 도시하고, (b)도는 히터의 풍량이 적을수록 건조효율이 상승되며, (c)도는 세탁조내의 습도가 적을수록 건조효율은 상승되고, (d)도는 세탁물의 양이 증가될수록 풍량 역시 증가되어야 함을 알 수 있고, 또한 (e)도는 세탁물의 양이 증가함에 따라 건조시간이 증가하며, (f)도는 세탁물의 양이 증가할수록 소비전력이 증가함을 알 수 있으며, 따라서 마이콤 내부에는 제4도와 같은 데이타에 의해 세탁조내의 온도, 습도 및 세탁물의 양에 비례하여 최적의 건조 조건을 유지할 수 있는 데이타가 내정된다.That is, Figure 4 (a) shows that the drying efficiency is increased as the temperature in the washing tank is increased, (b) is the drying efficiency is increased as the air volume of the heater is less, and (c) is the drying efficiency as the humidity in the washing tank is less Is increased, (d) is the increase in the amount of laundry, the air flow should also increase, and (e) is the drying time increases as the amount of laundry increases, (f) is the amount of laundry As the power consumption increases, the power consumption increases. Accordingly, data that can maintain optimal drying conditions in proportion to the temperature, humidity, and the amount of laundry in the washing tank are determined by the data shown in FIG.
이와 같은 데이타가 내장된 마이콤의 동작과정을 제5도에 도시된 흐름도에 의해 상세히 설명하면 다음과 같다.The operation of the microcomputer embedded with such data will be described in detail with reference to the flowchart shown in FIG.
통상적인 세탁, 헹굼, 탈수과정을 종료한 후 건조가 시작(단계101)되면 송풍팬과 히터(13)를 온시켜 (단계 102,103), 세탁조내에 열풍을 공급하고, 펄세이터(23)를 좌우로 수회 반복회전(단계 104)시키는 초기동작과정(L1)을 실행한다.After the normal washing, rinsing, and dehydration processes, drying starts (step 101), the blower fan and the heater 13 are turned on (steps 102 and 103) to supply hot air into the washing tank, and the pulsator 23 is left to right. An initial operation L1 is performed to repeat the rotation several times (step 104).
이후 무게감지수단(6)의 출력 데이타를 읽어 세탁물의 양을 측정(단계 105)하고, 이의 측정된 데이타를 저장(단계 106)함과 동시에 세탁물의 양에 따라 적정한 습도와 온도를 설정(단계 107,108)하는 포량제어과정(L2)을 수행한 다음 온도감지수단(3)으로부터 출력되는 데이타를 읽어들여 세탁조(21) 내부의 현재온도를 측정(단계 109)하고, 이의 측정된 온도가 포량제어과정(L2)에서 설정된 온도보다 높은지를 판단(단계 110)하여 세탁조(21) 내부온도가 설정 온도보다 높을 경우 히터(13)를 오프(단계 111)시키는 온도제어과정(L3)을 실행한다.Thereafter, the output data of the weight sensing means 6 is read to measure the amount of laundry (step 105), and the measured data thereof is stored (step 106), and at the same time, an appropriate humidity and temperature are set according to the amount of laundry (steps 107, 108). After performing the quantity control process (L2) to read the data output from the temperature sensing means (3) to measure the current temperature inside the washing tank 21 (step 109), and the measured temperature is measured by the quantity control process ( It is determined whether the temperature is higher than the temperature set in step L2 (step 110), and when the internal temperature of the washing tank 21 is higher than the set temperature, the temperature control process L3 is performed to turn off the heater 13 (step 111).
그 다음 습도감지수단으로부터 출력되는 신호를 읽어들여 세탁조(21) 내부의 습도를 측정하고, 이의 측정된 습도가 포량제어과정(L2)에서 설정된 온도보다 높은지를 판단(단계 110)하여 세탁조 내부온도가 설정온도보다 높을 경우 열풍배출수단(11)을 강풍으로 제어하여(단계 114) 습도를 신속히 낮추고, 설정습도보다 낮을 경우 열풍배출수단(11)을 약풍으로 제어(단계 115)하는 습도제어과정(L4)을 수행한다.Then, by reading the signal output from the humidity sensing means to measure the humidity inside the washing tank 21, it is determined whether the measured humidity is higher than the temperature set in the quantity control process (L2) (step 110) to determine the internal temperature of the washing tank. When the temperature is higher than the set temperature, the hot air discharge means 11 is controlled by strong wind (step 114), and the humidity is rapidly lowered. When the temperature is lower than the set humidity, the humidity control process (step 115) is performed to control the hot air discharge means 11 by mild wind. ).
이후 현재온도와 습도가 포량제어과정(L2)에서 설정된 종료온도 및 습도를 비교판단(단계 116,117)하여 세탁조(21) 내부의 현재의 온도와 습도가 종료시점의 온도 및 습도보다 적을 경우 히터를 오프(단계 118)시킨 다음 동작스위치가 오프상태임이 판단되면(단계 119) 열풍배출수단(11)의 구동을 정지(단계 120)시키는 건조완료과정(L5)을 수행함으로서 건조과정을 완료하게 되는 것이다.Then, when the current temperature and humidity are compared to the end temperature and humidity set in the quantity control process (L2) (steps 116 and 117), the heater is turned off when the current temperature and humidity in the washing tank 21 are less than the temperature and humidity at the end point. If it is determined (step 118) that the operation switch is in the off state (step 119), the drying process is completed by performing the drying completion process L5 of stopping the driving of the hot air discharge means 11 (step 120).
이상에서 상술한 바와같이 본 발명은 세탁조내의 소정위치에 습도감지수단과 열풍배출수단을 부가 설치하고, 마이크로 컴퓨터에서 온도감지수단 및 습도감지수단, 그리고 무게감지수단의 출력데이타를 비교 분석하여 세탁조내의 건조조건을 최적화 함으로서 건조효율 상승 및 건조시간을 단축하고 소비전력을 감소시킬 수 있는 것이다.As described above, in the present invention, the humidity sensing means and the hot air discharge means are additionally installed at a predetermined position in the washing tank, and the output data of the temperature sensing means, the humidity sensing means, and the weight sensing means in the microcomputer are compared and analyzed. By optimizing drying conditions, drying efficiency can be increased, drying time can be shortened, and power consumption can be reduced.
