An exhaust filter 15 is installed to remove lint and the like generated from the clothing in the clothes, and an exhaust fan 17 is installed at the middle of the exhaust duct 13 to suck and discharge the air inside the drum 3. have.

한편, 상기 배기덕트(13)는 상기 드럼(3)의 하측을 지나서 케이스(1)의 외부로 나온 다음 케이스(1)의 상측으로 연장되어 배출공기가 의류건조기의 상측으로 빠지게 되어 있다.On the other hand, the exhaust duct 13 passes through the lower side of the drum 3 to the outside of the case 1 and then extends to the upper side of the case 1 so that the exhaust air is discharged to the upper side of the clothes dryer.

또한, 상기 케이스(1)의 바닥면에는 상기 드럼(3) 및 배기팬(17)을 회전시키도록 구동하는 모터(19)가 설치되어 있고, 상기 모터(19)의 일측 모터축에는 모터(19)의 구동력을 상기 드럼(3)에 전달하여 드럼(3)을 회전시키는 벨트 등의 동력전달수단(21)이 설치되어 있으며, 상기 모터(19)는 상기 드럼(3) 및 배기팬(17)을 동시 구동시키도록 양측으로 모터축이 돌출된 구조로 되어 있다.In addition, a motor 19 for driving the drum 3 and the exhaust fan 17 to rotate is provided on the bottom surface of the case 1, and a motor 19 is provided on one side of the motor shaft of the motor 19.

상기와 같이 구성된 종래의 의류건조기에 있어서, 먼저 사용자가 드럼(3)내에 의류를 투입하고 도시되지 않은 조작부를 조작하여 건조코스, 건조시간 등을 입력한다음 동작버튼을 온시키면, 모터(19)가 구동하여 드럼(3) 및 배기팬(17)이 회전함과 동시에 히터(11)에 전원이 공급되어 도 1의 화살표 방향으로 도시한 바와 같이, 공기가 유동하기 시작한다.In the conventional clothes dryer configured as described above, first, a user inputs clothes into the drum 3, inputs a drying course, drying time, and the like by operating an operation unit (not shown), and then turns on the operation button. Is driven to rotate the drum 3 and the exhaust fan 17 and power is supplied to the heater 11 so that air starts to flow as shown in the arrow direction of FIG.

따라서, 배기팬(17)의 흡입력에 의해 외부 공기가 흡기덕트(7)를 통해 흡입될 때에 히터(11)에 의해 가열되어 드럼(3) 내부로 유입되고, 상기 드럼(3) 내부에 유입된 뜨거운 공기는 드럼(3) 내부의 의류를 건조시키면서 습공기로 변하여 배기덕트(13)를 통해 외부로 배출되는 건조행정을 수행한다.Therefore, when the outside air is sucked through the intake duct 7 by the suction force of the exhaust fan 17, it is heated by the heater 11 to flow into the drum 3, and the inside of the drum 3 flows in.

본 발명에 의한 의류건조기는 도 1에 도시한 종래의 구성과 동일하므로 동일명칭 및 동일부호를 명기하여 중복되는 설명을 생략한다.Clothes dryer according to the present invention is the same as the conventional configuration shown in Figure 1, so that the same description and the same reference numerals are omitted redundant description.

도 2는 본 발명의 일실시예에 의한 의류건조기의 건조제어장치의 구성블록도이다.2 is a block diagram of a drying control apparatus for a clothes dryer according to an embodiment of the present invention.

도 2에 도시한 바와 같이, 전원수단(100)은 외부로부터 공급되는 상용교류전압을 의류건조기의 구동에 필요한 소정의 직류전압으로 변환하여 출력하고, 운전조작수단(102)은 사용자가 원하는 건조조건(건조코스, 건조시간, 건조온도 등)을 입력하도록 다수의 기능버튼을 구비함은 물론, 의류건조기의 전원을 켜거나 끌 때 조작하는 전원버튼, 건조를 시작하거나 일시 정지할 때 선택하는 동작버튼 등을 구비하고 있다.As shown in Fig. 2, the power supply means 100 converts the commercial AC voltage supplied from the outside into a predetermined DC voltage required for driving the clothes dryer, and the operation operation means 102 is a drying condition desired by the user. It is equipped with a number of function buttons to input (drying course, drying time, drying temperature, etc.), power button for turning on / off the clothes dryer, and operation button for starting or pausing drying. Etc. are provided.

온도감지수단(104)은 히터(11)의 구동에 따라 변화하는 드럼(3) 내부의 온도를 감지하도록 서미스터 등으로 구성된다.The temperature sensing means 104 is composed of a thermistor or the like so as to sense the temperature inside the drum 3 which changes according to the driving of the heater 11.

그리고, 제어수단(106)은 상기 운전조작수단(102)에 의해 입력된 운전명령신호에 따라 의류건조기의 전체 동작을 제어하는 마이크로컴퓨터로써, 이 제어수단(106)은 상기 온도감지수단(104)에 의해 감지된 드럼(3) 내부의 초기온도(T1)와 소정시간 후의 온도(T2)를 비교하여 그 온도차(△T)에 따라 드럼(3)내에 투입된 의류의 무게 즉, 건조량을 판단하여 해당 건조량에 맞게 건조시간 및 건조온도 등을 조절하는 건조행정을 제어한다.In addition, the control means 106 is a microcomputer that controls the overall operation of the clothes dryer according to the operation command signal input by the driving operation means 102, and the control means 106 is the temperature sensing means 104. Compare the initial temperature T1 inside the drum 3 sensed by the temperature T2 after a predetermined time and determine the weight, i.e., drying amount, of the clothes put into the drum 3 according to the temperature difference ΔT. Control drying operation to adjust drying time and drying temperature according to drying amount.

또한, 모터구동수단(108)은 상기 제어수단(106)으로부터 출력되는 제어신호를 받아서 상기 드럼(3) 및 배기팬(17)을 회전시켜 의류를 건조시키도록 모터(19)를 구동제어하고, 히터구동수단(110)은 상기 제어수단(106)으로부터 출력되는 제어신호를 받아서 상기 드럼(3) 내부로 흡입되는 공기를 가열하여 의류를 건조시키도록 히터(11)를 구동제어한다.In addition, the motor driving means 108 receives the control signal output from the control means 106 and drives the motor 19 to dry the clothes by rotating the drum 3 and the exhaust fan 17, The heater driving means 110 receives the control signal output from the control means 106 and drives the heater 11 to dry the clothes by heating the air sucked into the drum 3.

또, 표시수단(112)은 상기 운전조작수단(102)에 의해 입력되는 건조조건과 건조진행상태를 표시한다.In addition, the display means 112 displays a drying condition and a drying progress state input by the driving operation means 102.

이하, 상기와 같이 구성된 의류건조기의 건조제어방법의 작용효과를 설명한다.Hereinafter, the effect of the drying control method of the clothes dryer configured as described above will be described.

도 3은 본 발명에 의한 의류건조기의 건조제어 동작순서를 도시한 플로우챠트로서, 도 3에서 S는 스텝(STEP)을 표시한다.3 is a flowchart showing a drying control operation procedure of the clothes dryer according to the present invention, in which S denotes a step.

먼저, 의류건조기에 전원이 인가되면, 전원수단(100)에서는 외부로부터 공급되는 상용교류전압을 의류건조기의 구동에 필요한 소정의 직류전압으로 변환하여 각 구동회로 및 제어수단(106)에 출력한다.First, when power is applied to the clothes dryer, the power supply means 100 converts a commercial AC voltage supplied from the outside into a predetermined DC voltage required for driving the clothes dryer, and outputs it to each driving circuit and the control means 106.

따라서, 상기 제어수단(106)에서는 전원수단(100)으로부터 출력되는 직류전압을 입력받아 의류건조기의 기능을 초기화시킨다.Therefore, the control means 106 receives the DC voltage output from the power supply means 100 to initialize the function of the clothes dryer.

이때, 스텝S1에서는 사용자가 도어(5)를 열고 드럼(3)내에 의류(세탁물)를 투입한다음, 운전조작수단(102)을 조작하여 원하는 건조조건(건조코스, 건조시간, 건조온도 등)을 입력하고 동작버튼을 온시키면, 상기 운전조작수단(102)으로부터 건조시작신호가 제어수단(106)에 입력된다.At this time, in step S1, the user opens the door 5, injects clothes (laundries) into the drum 3, and then operates the driving operation unit 102 to operate desired drying conditions (drying course, drying time, drying temperature, etc.). Is input and the operation button is turned on, the drying start signal is input to the control means 106 from the operation operation means 102.

이에 따라, 스텝S2에서 제어수단(106)은 동작버튼이 온되었는지를 판별하여, 동작버튼이 온되지 않으면(NO일 경우) 스텝S2이하의 동작을 반복수행한다.Accordingly, in step S2, the control means 106 determines whether the operation button is on, and if the operation button is not on (NO), the operation of step S2 or less is repeated.

상기 스텝S2에서의 판별결과, 동작버튼이 온되면(YES일 경우) 스텝S3으로 나아가서 건조행정을 시작하기 전 드럼(3) 내부의 초기온도(TI)를 온도감지수단(104)에서 감지하여 제어수단(106)에 출력한다.As a result of the discrimination in step S2, when the operation button is turned on (YES), the process proceeds to step S3 and the temperature sensing means 104 senses and controls the initial temperature TI inside the drum 3 before starting the drying operation. Output to the means 106.

이어서, 스텝S4에서 제어수단(106)은 드럼(3)내에 투입된 의류를 건조시키도록 모터구동수단(108)과 히터구동수단(110)에 제어신호를 출력한다.Then, in step S4, the control means 106 outputs a control signal to the motor driving means 108 and the heater driving means 110 to dry the clothes put into the drum 3.

따라서, 상기 모터구동수단(108)에서는 제어수단(106)으로부터 출력되는 제어신호를 입력받아 모터(19)를 구동시킨다.Accordingly, the motor driving means 108 receives the control signal output from the control means 106 to drive the motor 19.

상기 모터(19)가 구동되면, 모터(19)의 일측 모터축에 설치된 동력전달수단(21)에서 모터(19)의 구동력을 드럼(3)에 전달하여 드럼(3)을 회전시키므로 드럼(3) 내부의 의류가 회전하면서 뒤섞이게 되고, 모터(19)의 타측 모터축에 설치된 배기팬(17)이 회전함에 따라 도 1의 화살표 방향으로 도시한 바와 같이, 공기가 유동하기 시작한다.When the motor 19 is driven, the power transmission means 21 installed on one side of the motor shaft of the motor 19 transmits the driving force of the motor 19 to the drum 3 so as to rotate the drum 3 and thus the drum 3. The inner garments are mixed as they rotate, and as the exhaust fan 17 installed on the other motor shaft of the motor 19 rotates, as shown in the arrow direction of FIG. 1, air starts to flow.

이와 동시에, 상기 히터구동수단(110)에서는 제어수단(106)으로부터 출력되는 제어신호를 입력받아 히터(11)를 구동시킨다.At the same time, the heater driving means 110 receives the control signal output from the control means 106 to drive the heater 11.

상기 히터(11)가 구동되면, 배기팬(17)의 흡입력에 의해 외부 공기가 흡기덕트(7)를 통해 흡입될 때에 히터(11)에 의해 가열되어 드럼(3) 내부로 유입되고, 상기 드럼(3) 내부에 유입된 뜨거운 공기는 드럼(3) 내부의 의류를 건조시키면서 습공기로 변하여 배기덕트(13)를 통해 외부로 배출되는 건조행정을 수행하기 시작한다.When the heater 11 is driven, when the outside air is sucked through the intake duct 7 by the suction force of the exhaust fan 17, it is heated by the heater 11 to flow into the drum 3, and the drum (3) The hot air introduced into the inside of the drum 3 turns into wet air while drying the clothes inside the drum 3 and starts to perform the drying stroke discharged to the outside through the exhaust duct 13.

이때, 스텝S5에서는 상기 모터(19) 및 히터(11)의 구동에 따라 수행되는 건조행정이 소정시간(예를 들면, 1분)을 경과하였는지를 판별하여, 소정시간을 경과하지 않으면(NO일 경우) 소정시간이 경과할 때까지 상기 스텝S4로 복귀하여 스텝S4이하의 동작을 반복 수행한다.At this time, in step S5, it is determined whether the drying operation performed according to the driving of the motor 19 and the heater 11 has passed a predetermined time (for example, one minute), and if the predetermined time has not elapsed (NO) The process returns to step S4 until a predetermined time elapses, and the operation of step S4 or less is repeated.

상기 스텝S5에서의 판별결과, 소정시간을 경과하면(YES일 경우) 스텝S6에서는 소정시간후의 드럼(3) 내부의 온도(T2)를 온도감지수단(104)에서 감지하여 제어수단(106)에 출력한다.As a result of the determination in step S5, when a predetermined time has elapsed (YES), in step S6, the temperature sensing unit 104 senses the temperature T2 inside the drum 3 after the predetermined time and transmits it to the control unit 106. Output

따라서, 스텝S7에서 제어수단(106)은 온도감지수단(104)에 의해 감지된 초기온도(T1)와 소정시간후의 온도(T2)를 비교하여 드럼(3)내에 투입된 의류의 무게 즉, 건조량을 감지하기 위해 온도차(△T=T2-T1)를 산출한다.Therefore, in step S7, the control means 106 compares the initial temperature T1 sensed by the temperature sensing means 104 with the temperature T2 after a predetermined time to determine the weight, i.e., the drying amount, of the clothes put into the drum 3. The temperature difference (ΔT = T2-T1) is calculated for detection.
