Abstract

PURPOSE: A control method of a door opening in a drum washing machine is provided to additionally input the laundry into a washing tub during a washing. CONSTITUTION: In opening a door through pushing a door opening button, inputting the laundry into a washing tub and closing the door, water is supplied through a water supplying valve and a heater is driven. In pushing the door opening button, a microcomputer turns off the heater. A water level sensor detects a water level inside the tub. The microcomputer drains the water by driving a draining pump when the water level is over a predetermined value. A water temperature sensor detects a water temperature inside the tub. The microcomputer drops a water temperature by supplying cold water and drains the water up to the predetermined water level when the water temperature is over a predetermined value. The door is opened when the water level and the water temperature are under the predetermined values. In closing the door after additionally inputting the laundry, a washing is performed again. In pushing the door opening button over a predetermined time or twice within the predetermined time, the process is operated. Otherwise, the door is not opened.

드럼 세탁기의 도어 개방 제어 방법How to control the door opening of the drum washing machine

본 발명은 드럼 세탁기에 관한 것으로, 특히 세탁도중에도 세탁물을 세탁조내에 추가할 수 있도록 한 드럼 세탁기의 도어 개방 제어 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum washing machine, and more particularly, to a method of controlling a door of a drum washing machine in which laundry can be added to a washing tank even during washing.

일반적인 드럼세탁기는, 제1도 및 제2도에 도시된 바와 같이 세탁기의 전체시스템동작을 제어하는 마이컴(10)와, 급수밸브, 배수밸브펌프, 세탁모터등의 구동을 제어하는 부하구동부(20)와, 세탁조내의 수위를 감지하여 상기 마이컴(10)에 입력하는 수위센서부(30)와, 세탁조내의 수온을 감지하여 상기 마이컴(10)에 입력하는 수온센서부(40)와, 조내의 수위 또는 수온을 감지하여 도어개방을 방지하기 위한 도어 스위치(50)등으로 구성되어 있다.The general drum washing machine includes a microcomputer 10 for controlling the overall system operation of the washing machine as shown in FIGS. 1 and 2, and a load driving part 20 for controlling driving of a water supply valve, a drain valve pump, and a washing motor. ), The water level sensor unit 30 for detecting the water level in the washing tank and inputting it to the microcomputer 10, the water temperature sensor unit 40 for detecting the water temperature in the washing tank and inputting it to the microcomputer 10, and the water level in the tank. Or it is composed of a door switch 50 to detect the water temperature to prevent the door opening.

이러한 드럼세탁기의 세탁행정을 설명하면, 세탁행정시, 도어열림버튼(4)을 눌려 도어(2)를 개방하여, 세탁조내에 세탁물을 투입하고 도어(2)를 닫고 급수밸브를 통하여 일정수위 급수되면, 세탁모터 및 히터(5)가 구동된다.When the washing operation of the drum washing machine is described, when the washing operation is performed, the door 2 is opened by pressing the door open button 4, the laundry is put into the washing tank, the door 2 is closed, and the water level is supplied through the water supply valve. The washing motor and the heater 5 are driven.

이와 같이 일정수위 급수되고, 히터(5)가 구동되면, 사용자의 도어 열림버튼(4)을 눌러도 도어(2)가 열리지 않고 경고음이 발생된다. 이는, 사용자가 도어(2)를 개방하는 경우, 높은 온도의 물로 부터 사용자를 보호하기 위한 것으로, 온도를 감지하여 작동하는 바이메탈식 도어스위치 또는 수위를 감지하여 작동하는 마이콤식 도어스위치가 작동하기 때문이다.In this way, when the water level is supplied and the heater 5 is driven, the door 2 does not open even when the user presses the door open button 4, and a warning sound is generated. This is to protect the user from the high temperature water when the user opens the door 2, because the bimetallic door switch that operates by sensing the temperature or the microcomputer door switch that operates by sensing the water level is operated. to be.

따라서, 사용자가 세탁도중에 세탁물을 추가 투입하려면 세탁행정이 끝나고 배수가 되어야만 도어를 열 수 있으므로, 많은 시간을 기다려야하는 문제점과, 도어열림버튼을 눌렸을시 경고음이 발생하고 도어가 열리지 않아 사용자가 이를 불량으로 오인하는 문제점이 있었다.Therefore, when the user adds laundry during the washing process, the door can be opened only after the washing administration is finished and drained, and thus, the user needs to wait a lot of time, and when the door open button is pressed, a warning sound occurs and the door does not open. There was a problem that was mistaken for bad.

본 발명은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 세탁도중에도 세탁물을 세탁조내에 추가 투입할 수 있는 드럼 세탁기의 도어 개방 제어 방법의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, it is an object of the present invention to provide a door opening control method of the drum washing machine that can be added to the laundry in the laundry.

상기 목적을 달성하기 위하여, 본 발명의 드럼 세탁기의 도어 개방 제어 방법은, 세탁도중 도어열림버튼이 눌려지면, 수온 또는 수위를 감지하여 설정수온 또는 설정수위이하이면 도어가 개방되는 것을 특징으로 한다.In order to achieve the above object, the door opening control method of the drum washing machine of the present invention, when the door opening button is pressed during washing, it characterized in that the door is opened when the water temperature or the water level is set to detect the water temperature or the water level or less.

이하, 첨부도면에 의거하여 본 발명의 드럼 세탁기의 도어 개방 제어 방법을 상세히 설명한다.Hereinafter, the door opening control method of the drum washing machine of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 드럼 세탁기의 도어 개방 제어 방법은, 제1도, 제2도 및 제4도에 도시된 바와 같이, 세탁도중 도어열림버튼(4)이 눌려지면, 세탁조내의 수온 또는 수위를 감지하여 설정수온 또는 설정수위이하이면 도어(2)을 개방하는 것이다. 한편, 상기 감지된 수온이, 설정온도이상이면, 수온을 하강하도록 냉수를 급수하고, 설정수위까지 배수한 후 도어(2)를 개방한다. 또한, 감지된 수위가 설정수위이상이면, 설정수위까지 배수한 후 도어(2)를 개방한다.Door opening control method of the drum washing machine of the present invention, as shown in Figs. 1, 2 and 4, when the door opening button 4 is pressed during washing, it is set by sensing the water temperature or water level in the washing tank When the water temperature or the set water level is below, the door 2 is opened. On the other hand, if the detected water temperature is above the set temperature, cold water is supplied to lower the water temperature, drained to the set water level, and then the door 2 is opened. In addition, if the detected water level is higher than the set water level, the door 2 is opened after draining to the set water level.

이하, 본 발명의 드럼 세탁기의 도어 개방 제어 방법의 작용을 설명한다.Hereinafter, the operation of the door opening control method of the drum washing machine of the present invention will be described.

세탁행정시, 도어열림버튼(4)을 눌러 도어를 개방하여, 세탁조내에 세탁물을 투입하고 도어(2)를 닫으면, 급수밸브를 통하여 일정수위까지 급수되고, 히터(5)가 구동된다. 사용자가 세탁도중에 세탁물을 추가 투입하고자 도어열림버튼(4)을 누르면, 마이컴(10)은 히터(5)를 오프하고, 수위센서부(30)에서 조내의 수위를 감지하여 감지신호를 마이컴(10)에 보내면, 마이컴(10)는 설정수위이상인가를 판단하고, 설정수위이상이면, 배수펌프를 구동하여 설정수위까지 배수한다. 한편, 수온센서부(40)에서 조내의 수온을 감지하여 감지신호를 마이컴(10)에 보내면, 마이컴(10)를 설정수온이상인가를 판단하고, 설정수온이상이면, 급수밸브를 구동하여 냉수를 급수하여 수온을 하강하고 배수펌프를 구동하여 설정수위까지 배수한다. 이와 같은 과정을 거쳐 설정수온 및 설정수위이하가 되면, 도어(2)를 개방한다. 사용자가 조내에 세탁물을 추가 투입한 후 도어(2)를 닫으면 세탁이 다시 진행된다. 한편, 도어 열림 버튼(4)은 일정시간 이상 눌려지던가 또는 일정시간이내에 두번 연속으로 눌러졌을 경우 동작하도록 하여, 사용자가 세탁도중 도어열림버튼(4)을 실수로 누르는 경우, 도어의 열림을 방지하도록 한다.At the washing stroke, the door is opened by pressing the door open button 4, the laundry is put into the washing tank, and the door 2 is closed. The water is supplied to a predetermined level through the water supply valve, and the heater 5 is driven. When the user presses the door open button 4 to add laundry while washing, the microcomputer 10 turns off the heater 5 and detects the water level in the tank at the water level sensor unit 30 to detect the microcomputer signal 10. ), The microcomputer 10 determines whether or not the set water level is equal to or higher than the set water level. On the other hand, when the water temperature sensor unit 40 detects the water temperature in the tank and sends a detection signal to the microcomputer 10, it is determined whether the microcomputer 10 is above the set water temperature. The water temperature is lowered by water supply, and the drainage pump is driven to drain to the set water level. When the set water temperature and the set water level are lower than the above, the door 2 is opened. If the user closes the door 2 after the additional laundry is added to the tank, the washing proceeds again. On the other hand, the door open button (4) is operated when pressed for more than a predetermined time or twice in a row within a predetermined time, so that when the user accidentally press the door open button (4) during washing, to prevent the door from opening do.

이상, 설명한 바와 같이, 본 발명에 따르면, 세탁도중에도 일정조건 하에서 도어가 개방가능하도록 함으로서 세탁도중에 세탁물을 세탁조내에 추가 투입할 수 있다.As described above, according to the present invention, by allowing the door to be opened under a predetermined condition even during washing, laundry can be added to the washing tank during the washing.
