본 발명은 세탁기의 도어열림경보발생방법에 관한 것으로, 특히 세탁시 세탁행정의 종류에 따라 도어열림을 감지하고 경보발생을 하도록 한 세탁기의 도어열림경보발생방법에 관한 것이다.The present invention relates to a method of generating a door opening alarm of a washing machine, and more particularly, to a method of generating a door opening alarm of a washing machine for detecting a door opening and generating an alarm according to a type of washing administration during washing.

일반적인 세탁기에서 일련의 세탁행정 중 헹굼탈수행정이나 본 탈수행정 전에 세탁기의 도어가 열려져 있는 경우 부저음을 발생시켜서 이를 경보함과 아울러 콘트롤판넬의 표시부를 통해서 에러경보 LE라는 문자를 표시하여 사용자로 하여금 열려진 도어를 닫도록 유도하고 있다.In a typical washing machine, when the washing machine's door is opened before the rinsing dehydration stroke or this dehydration stroke, the buzzer sounds and the error alarm LE is displayed on the control panel. It is trying to close the door.

또한, 상기 헹굼탈수행정이나 본 탈수행정 중에 도어를 열었을 경우에도 세탁기는 세탁기의 급제동하면서 동작을 중지함과 아울러 도어가 열였음을 경보하도록 되어 있다.Further, even when the door is opened during the rinsing dehydration stroke or the dehydration stroke, the washing machine stops the operation while suddenly braking the washing machine and alerts that the door is opened.

그 이유는 상기 헹굼탈수행정이나 본탈수행정 시에는 세탁조가 일방향으로 고속회전을 하게 되므로 이 고속회전하는 세탁조에 의하여 인체에 손상 또는 사고를 미연에 방지하기 위해서이다.The reason is that when the rinsing dehydration stroke or the main dehydration stroke, the washing tank is rotated in one direction at high speed to prevent damage or accident to the human body by the high-speed rotating washing tank.

그러나 도어가 열려 있는 경우에도 세탁이 중지되지 않고 진행하는 경우가 있는데, 이는 세탁행정시나 헹굼행정 시인데, 상기 세탁 및 헹굼행정 시에는 세탁조가 회전하는 것이 아닌, 감속된 펄세이터의 정, 역회전이기 때문에 인체의 손상이나 사고를 일으킬 우려가 없기 때문에 경보를 발생하지 않게 된다.However, even when the door is open, the washing may proceed without stopping, which is during the washing or rinsing stroke, and the washing tank does not rotate during the washing and rinsing stroke, but the forward and reverse rotation of the decelerated pulsator Because of this, the alarm does not occur because there is no risk of damage or accident.

그러므로 세탁시 사용자가 부주의에 의하여 도어를 열어놓고 일련의 세탁행정을 수행하는 경우, 종래의 세탁기에서는 도어 개폐상태에 관계 없이 세탁행정을 수행하고 이어서 헹굼을 진행하되, 헹굼탈수행정에 이르러서야 비로서 도어의 열림을 경보하도록 되어 있어, 사용자가 세탁도중에 상기 도어열림 경보를 듣지 못했거나 혹은 자리를 비웠을 경우, 막상 세탁이 완료되었는가를 확인하여 보면 세탁이 중단된 채 그대로 있게 되므로, 재세탁을 하거나 혹은 세탁행정을 다시 선택하여 세탁하여야 하는 번거로움을 가지고 있었다.Therefore, when a user performs a series of washing strokes while the door is inadvertently opened during washing, the washing machine performs the washing stroke and proceeds with rinsing regardless of the door opening and closing state in the conventional washing machine. When the user does not hear the door open alarm or is away during washing, the user checks whether the washing is completed, and the washing is stopped. Or was the hassle of having to wash again to select the washing administration.

따라서 본 발명의 목적은 세탁시 도어열림을 감지 판단하되, 세탁행정이 일반행정이나 특정행정이 선택된 상태에서 도어가 열려져 있으면 도어열림을 경보하도록 함으로써, 세탁도중에 행정이 중단되는 것을 사전에 방지할 수 있도록 하고자 하는데 있다.Accordingly, an object of the present invention is to detect the door opening during washing, but if the washing administration is a general administration or a specific stroke is selected to open the door to alert the door opening, it can be prevented in advance to stop the stroke during washing. I want to be.

상기의 목적을 실현하기 위하여 본 발명은 초기화 상태에서 사용자가 세탁하고자 하는 일련의 세탁행정이나 특정행정(세탁,헹굼,탈수전용 혹은 세탁,헹굼 또는 헹굼,탈수)를 선택한 상태에서 세탁시작신호가 입력되었는가를 판단하여 상기 세탁신호가 입력되어 있지 않으면 대기하는 단계와, 상기 단계에서 세탁시작 신호가 입력되었으면 도어가 열려져 있는가를 판단하는 단계와, 상기 단계에서 도어가 열려져 있지 않으면 상기 선택된 상태의 행정을 수행하고, 반면에 도어가 열려져 있으면 탈수행정이 선택되었는가를 판단하는 단계와, 상기 단계에서 탈수행정이 선택되어 있으면 경보를 발생하는 단계와, 상기 단계에서 탈수행정이 선택되어 있지 않으면 헹굼행정이 선택되어 있는 가를 판단하는 단계와, 상기 단계에서 헹굼행정이 선택되어 있지 않으면, 상기 대기상태를 유지하고, 반면에 헹굼행정이 선택되어 있으면 경보를 발생하도록 단계로 이루어짐을 특징으로 한다.In order to achieve the above object, the present invention provides a washing start signal in a state in which a user selects a series of washing administrations or specific administrations (laundry, rinsing, dehydrating only or washing, rinsing, rinsing, or dehydrating) to be washed. Determining whether the washing signal is inputted, and if the washing signal is not input, determining whether the door is open if the washing start signal is input, and performing the stroke of the selected state if the door is not opened. On the other hand, if the dehydration stroke is selected if the door is open, the step of generating an alarm if the dehydration stroke is selected in the step, and if the dehydration stroke is not selected in the step, the rinsing stroke is selected Judging whether there is a rinse stroke. If, it characterized by made of an step to maintain the stand-by state, and if, while the rinsing cycle is selected to generate an alarm.

제3도는 본 발명 세탁행정의 종류별 도어열림 경보발생을 나타낸 도표이다.3 is a diagram showing a door open alarm generation according to the type of laundry administration of the present invention.

상기와 같이 이루어지는 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention made as described above are as follows.

먼저, 세탁기의 마이콤(나)에 제3도에 도시된 세탁행정의 종류별 도어열림 경보 발생에 대한 데이터를 입력시켜 놓은 상태에서, 사용자가 세탁을 하기 위하여 세탁기에 전원을 인가하고, 이어서 세탁물을 세탁조에 넣은 후 세탁하고자 하는 일련의 세탁행정에 대한 운전신호를 운전신호입력부(가)를 통해서 상기 마이콤(나)에 입력시키면, 상기 마이콤(나)에서는 세탁시작신호입력판단단계(20)로 가서 세탁시작신호가 입력되었는가를 판단하게 되고, 이때 세탁시작신호가 입력되지 않았으면 대기단계(21)로 가서 대기하면서 세탁시작신호가 입력되기를 기다리게 된다.First, the user inputs power to the washing machine for washing in a state in which data on the door open alarm occurrence according to the type of washing administration shown in FIG. 3 is input to the microcomputer (b) of the washing machine, and then the laundry is washed in the washing tank. After inputting the driving signal for a series of washing administration to be washed to the microcomputer (B) through the driving signal input unit (A), the microcomputer (B) goes to the washing start signal input determination step (20) to wash It is determined whether the start signal has been input. At this time, if the washing start signal is not input, the process goes to the waiting step 21 and waits for the washing start signal to be input.

그러나 상기 세탁시작신호입력판단단계(20)에서 세탁시작신호가 입력되게 되면 상기 마이콤(나)에서 기설정된 소정의 프로그램에 의하여 도어열림판단단계(22)로 가서 도어열림감지부(다)를 통해서 세탁기의 도어가 열려져 있는가를 판단하게 되고, 이 때 판단결과 도어가 열려져 있지 않으면, 상기 운전신호입력부(가)에서 선택된 세탁행정으로 세탁을 진행하게 되고, 반면에 상기 도어가 열려져 있는 것을 판단되면 상기 마이콤(나)에서는 탈수행정선택판단단계(23)로 가서 상기 선택된 세탁행정 중 탈수행정이 선택되어 있는가를 판단하게 되고, 이때 상기 탈수행정이 선택되어 있으면, 상기 마이콤(나)에서 탈수시 세탁조의 고속회전으로 인한 인체의 손상이나 사고를 방지하기 위하여 세탁을 진행하지 않고, 경보단계(24)로 가서 경보표시부(라)를 제어하여 경보하여 사용자에게 도어가 열려 있음을 경보하게 된다.However, when the washing start signal is input in the washing start signal input judging step 20, the microcomputer (b) goes to the door opening judging step 22 by a predetermined program, through the door opening detecting unit (C). If it is determined that the door of the washing machine is open, if the door is not opened at this time, the driving signal input unit proceeds to the washing operation selected by the washing operation, whereas if it is determined that the door is opened, the microcomputer (B) In the dehydration administration selection step (23), it is determined whether a dehydration administration is selected among the selected washing administrations, and if the dehydration administration is selected, the high speed rotation of the washing tank when dehydration is performed in the microcomputer (b) To prevent damage or accidents caused by humans, go to the alarm step 24 and control the alarm display unit without proceeding to washing. This alerts the user that the door is open.

그러나 상기 탈수행정선택판단단계(23)에서 탈수행정이 선택되어 있지 않으면 상기 마이콤(나)에서 헹굼행정선택판단단계(25)로 가서 선택된 세탁행정 중 헹굼행정이 선택되어 있는가를 판단하게 되고, 이때 상기 헹굼행정이 선택되어 있으면, 상기 마이콤(나)에서 헹굼행정 중 헹굼탈수시 세탁조의 고속회전으로 인한 인체의 손상이나 사고를 방지하기 위하여 세탁을 진행하지 않고, 경보단계(24)로 가서 경보표시부(라)를 제어하여 경보하여 사용자에게 도어가 열려 있음을 경보하게 되지만, 상기 선택된 세탁행정 중 헹굼행정이 선택되어 있지 않으면, 세탁전용으로 판단하여 세탁행정만을 수행하고 완료하게 되는 것이다.However, if a dehydration stroke is not selected in the dehydration stroke selection step 23, the microcomputer (b) goes to the rinsing stroke selection step 25 to determine whether a rinsing stroke is selected among the selected washing strokes. If the rinsing stroke is selected, in order to prevent damage or accident of human body due to the high-speed rotation of the washing tank during the rinsing dehydration of the rinsing stroke in the microcomputer (b) without going through the washing, go to the alarm step (24) and the alarm display unit ( D) to control the alarm to alert the user that the door is open, but if the rinsing stroke is not selected among the selected washing stroke, it is determined as the washing only to perform the washing stroke and complete.

그러므로 일련의 세탁행정시 세탁전용만을 제외하고는 통상적으로 사용하게 되는 일련의 세탁, 헹굼, 탈수 행정시에는 도어가 열려져 있으면 세탁을 진행하지 않고 경보를 발하게 되므로, 통상적인 세탁 시에도 도어열림으로 인하여 세탁이 중단되지 않게 하면서 세탁을 할 수 있게 되는 것이다.Therefore, in the case of a series of washing, rinsing, and dehydration strokes that are normally used except for washing only during a series of washing administrations, an alarm is issued without proceeding when the door is opened. You can do the laundry without interrupting the laundry.

이상에서 설명한 바와 같이 본 발명은 세탁시 도어열림을 감지 판단하고, 일반세탁행정이나 혹은 특정행정이 선택되었는가를 판단하여, 상기 일반행정이나 특정행정이 선택된 상태에서 도어가 열려져 있으면 도어열림을 경보하도록 함으로써, 세탁도중에 행정이 중단되는 것을 사전에 방지하면서 세탁할 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention detects the door opening during washing, determines whether the general washing administration or the specific administration is selected, and alerts the door opening when the door is opened in the state where the general administration or the specific administration is selected. By doing so, it is possible to provide the effect of washing while preventing the stroke is interrupted during washing.
