본 발명은 전자동 세탁기의 세탁조(Tub) 세정방법에 관한 것으로서, 더욱 상세하게는 전자동 세탁기의 세탁조 내부에 기생하는 세균 및 오염물질을 효율적으로 제거할 수 있도록 한것이다.The present invention relates to a washing tub (Tub) cleaning method of a fully automatic washing machine, and more particularly to efficiently remove the parasitic bacteria and contaminants in the washing tank of the automatic washing machine.

종래의 전자동 세탁기는 제1도 및 제2도에 나타낸 바와같이, 터브(2a)의 상부에 설치된 오존가스 발생기(10a)에 실리콘 호스로 되어 오존가스의 공급로인 제1가스유로(17) 및 산소가스를 포함한 원료가스의 공급로인 제2가스유로(18)가 각각 연통되어 상기 오존가스 발생기(10a)는 제2가스유로(18)를 통해 유입되는 원료가스로부터 제1가스유로(17)에 공급되는 오존가스를 생성시키는 역할을 하고, 상기 오존가스 발생기(10a)와 기액혼합로(19) 사이의 제1가스유로(17)에는 제1가스유로(17)에서 오존가스 발생기(10a)에 흐르려고 하는 물의 흐름을 정지시킴과 동시에 오존가스 발생기(10a)로부터의 오존가스를 통과시키는 역지밸브(1la)가 설치되며, 오존가스 발생기(10a)에서 생성된 오존가스는 오존가스 발생기(10a)에시 제1가스유로(17)를 통해 기액혼합로(19)에 공급하게 된다.In the conventional fully automatic washing machine, as shown in FIGS. 1 and 2, the first gas flow path 17, which is a supply path for ozone gas, is a silicone hose in the ozone gas generator 10a provided on the top of the tub 2a. The second gas passage 18, which is a supply passage of the raw material gas including oxygen gas, is connected to each other so that the ozone gas generator 10a is connected to the first gas passage 17 from the raw material gas introduced through the second gas passage 18. It serves to generate the ozone gas supplied to the first gas passage 17 between the ozone gas generator 10a and the gas-liquid mixing passage 19 to the ozone gas generator 10a in the first gas passage 17. A check valve 1la is provided for stopping the flow of water to be flowed to and passing the ozone gas from the ozone gas generator 10a, and the ozone gas generated by the ozone gas generator 10a is ozone gas generator 10a. To the gas-liquid mixture (19) through the first gas flow path (17) do.

또한, 제1가스유로(17) 및 급수로(20)에 연통되는 기액혼합료(19)는 양단에 기액혼합로(19)의 부압상태를 형성하기 위하여 오리피스(21)가 설치되어 상기 제1가스유로(17)를 통해 기액혼합로(19)의 내부로 유입되는 오존가스를 기액혼합로(19)내에서 물과 혼합시키게 된다.In addition, the gas-liquid mixture 19 communicated with the first gas passage 17 and the water supply passage 20 has an orifice 21 installed at both ends to form a negative pressure state of the gas-liquid mixture 19. The ozone gas flowing into the gas-liquid mixing passage 19 through the gas flow passage 17 is mixed with water in the gas-liquid mixing passage 19.

그러나, 이와같은 종래의 전자동 세탁기는 터브(2a)내에 발생하여 오존수화되지 못한 오존가스를 제거할 수 있는 구조적인 장치가 설치되어 있지 않고, 특히 발생된 오존가스와 오존수가 세탁기의 상부에서 투입되어 자유낙하되므로 인해 불필요한 오존가스의 발생량이 증가하여 세탁기 사용자가 안전한 상태로서 효율적인 세탁작업을 수행할 수 없으며, 오존가스를 물에 용해시키는 과정에서 오존가스를 미세기체화 시키는 장치가 설치되어 있지 않으므로 인해 고농도의 오존수를 발생시키지 못하게 되는 등의 많은 문제접이 있었다.However, such a conventional fully automatic washing machine is not provided with a structural device capable of removing ozone gas that has not occurred in the tub 2a due to ozone hydration. In particular, the generated ozone gas and ozone water are introduced from the upper part of the washing machine. Due to the free fall, the amount of unnecessary ozone gas is increased and the washing machine user is in a safe state and cannot perform efficient washing work, and because there is no device to make ozone gas into a micro gas in the process of dissolving ozone gas in water, There have been many problems such as not being able to generate ozone water.

본 발명은 상기한 제반문제점을 해결하기 위한 것으로서, 본 발명은 전자동 세탁기의 세탁조내부에 기생하는 세균 및 오염물질을 효율적으로 제거할 수 있도록 하여 제품의 신뢰성을 향상시킬 수 있는 전자동 세탁기의 세탁조 세정방법을 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention to efficiently remove the parasitic bacteria and contaminants in the washing tank of the automatic washing machine washing machine washing method of the automatic washing machine which can improve the reliability of the product The purpose is to provide.

이와 같이 이루어진 본 발명은 제3도 내지 제6도에 나타낸 바와같이, 전자동 세탁기의 일반적인 세탁행정 전후에 세탁조(15)를 세정할 수 있는 코스를 추가한 것으로 일반적인 세탁행정에 대한 설명은 종래와 같아서 생략하고 본 발명인 세탁조 세정코스에 대해 집중적으로 설명하면 다음과 같다.As shown in FIGS. 3 to 6, the present invention made as described above adds a course for washing the washing tub 15 before and after the general washing stroke of the automatic washing machine. Omitted and described intensively for the present invention washing tank cleaning course as follows.

전자동 세탁기의 일반적인 세탁행정의 전후에 세탁조(15)를 세정하기 위하여 사용자가 세탁조 세정코스를 선택하면, 마이콤(도시는 생략함)이 자동으로 공급수를 냉수로 선택하고 세탁조(15)의 수위를 고수위로 선택한다.When the user selects the washing tank washing course to clean the washing tank 15 before and after the general washing operation of the automatic washing machine, the microcomputer (not shown) automatically selects the supply water as cold water and sets the water level of the washing tank 15. Choose a high water level.

그리고, 사용자가 세탁조 세정시간을 설정하고 동작 및 일시정지버튼을 눌러주면 세탁조(15)내의 내부로 급수가 시작하게 됨과 동시에, 본체(1)상의 톱커버(2)상부에 착탈가능하게 설치된 박스(3)내의 오존가스 발생기(5) 및 정수용해조(10)가 동작되어 정수 및 오존가스 발생기능이 시작하게 된다.Then, when the user sets the washing tank cleaning time and presses the operation and pause button, water supply starts in the washing tank 15, and a box detachably installed on the top cover 2 on the main body 1 ( 3) The ozone gas generator 5 and the purified water dissolution tank 10 are operated to start the purified water and ozone gas generating functions.

정수 및 가스발생기능이 온되면서 물이 공급되어 세탁조(15)의 내부가 고수위에 도달하면, 펄세이터(29)를 동작시켜 세탁조(l5)내의 수위가 고수위에 도달하더라도 간헐적으로 급수를 하는 주수를 함과 동시에 시간을 카운트하고, 카운트된 시간이 사용자에 의해 설정된 세정시간과 같을때, 정수 및 오존가스 발생기능을 오프시키며, 상기 펄세이터(29)의 동작을 정지시켜 주수를 정지하게 된다.When the water and the gas generating function is turned on and the water is supplied and the inside of the washing tank 15 reaches a high water level, the pulsator 29 is operated so that the drinking water intermittently supplies water even if the water level in the washing tank l5 reaches the high water level. At the same time, the time is counted, and when the counted time is equal to the cleaning time set by the user, the purified water and ozone gas generating function are turned off, and the operation of the pulsator 29 is stopped to stop drinking water.

그후, 배수 및 탈수행정을 선택하여 배수 및 탈수시켜 세탁조세정코스를 완료함에 따라 세탁조(15)내에 기생하는 세균 및 오염물질을 제거할 수 있게 된다.Then, by selecting the drainage and dehydration stroke drainage and dehydration to complete the washing tank cleaning course it is possible to remove the parasitic bacteria and contaminants in the washing tank (15).
