Description
본 발명은 드럼 세탁기에 있어서, 소정의 세탁물을 세탁할 경우에 순환펌프에 의해 펌핑되어 순환되는 순환수와 증기 발생부에서 발생된 증기를 드럼 내의 세탁물로 균일하게 분사하는 드럼 세탁기의 순환수/증기 공급장치에 관한 것이다.The present invention relates to a drum washing machine, wherein when a predetermined laundry is washed, the circulating water / steam of a drum washing machine which uniformly injects the circulating water circulated by the circulation pump and the steam generated in the steam generator to the laundry in the drum. It relates to a supply device.
일반적으로 드럼 세탁기는 드럼의 회전으로 생긴 낙차를 이용하여 두드려 빠는 방식으로 세탁물을 세탁하는 세탁기로서, 펄세이터식 세탁기에 비하여 세탁물의 꼬임에 의한 손상이 적어 섬세한 의류도 세탁이 가능한 장점이 있다.In general, a drum washing machine is a washing machine that washes laundry by tapping and sucking by using a drop generated by the rotation of the drum. Compared to a pulsator type washing machine, the drum washing machine has less damage due to the twist of the laundry, and thus the delicate clothes can be washed.
이러한 드럼 세탁기에 있어서, 세탁물로 물을 분사하여 적시거나 또는 세탁을 수행할 경우에 드럼 외측의 외조에 고여있는 물을 순환펌프가 펌핑하고, 펌핑한 물을 드럼 내의 세탁물로 분사하고 있다.In such a drum washing machine, when the water is sprayed into the laundry to wet or wash, the circulation pump pumps the water accumulated in the outer tank outside the drum, and the pumped water is sprayed into the laundry in the drum.
그리고 드럼 세탁기는 세탁물을 가열 세탁할 수 있도록 하기 위하여 히터를 구비하고, 그 히터로 세탁수를 가열하여 세탁물을 가열하고 있다.And the drum washing machine is provided with a heater in order to be able to wash the laundry by heating, the laundry is heated by the heater to heat the laundry.
그러나 상기 세탁수를 가열하여 세탁물을 가열하는 것은 세탁물이 물 속에 충분히 잠기도록 해야 되어 물의 소모량이 많고, 또한 급수가 완료된 후 히터로 세탁수를 가열해야 되어 세탁시간이 길어지게 되는 등의 여러 가지 문제점이 발생한다.However, the heating of the laundry by heating the wash water requires a large amount of water so that the laundry is sufficiently immersed in the water, and the washing time is long because the washing water is heated by a heater after water supply is completed. This happens.
그러므로 본 발명의 발명자들은 드럼 세탁기내에 별도의 증기 발생기를 구비하고, 증기 발생기에서 발생하는 증기를 세탁물로 분사함으로써 세탁물이 물 속에 충분히 잠기도록 않아도 증기로 세탁물을 가열할 수 있어 물의 소모량이 줄고, 또한 세탁물을 가열 세탁하는 효과를 가질 수 있도록 함은 물론 세탁시간을 단축할 수 있도록 하였다.Therefore, the inventors of the present invention are provided with a separate steam generator in the drum washing machine, by spraying the steam generated in the steam generator to the laundry can be heated to the laundry without steam to be sufficiently submerged in the water to reduce the consumption of water, The laundry was heat-washed, as well as to shorten the washing time.
상기 순환수 및 증기를 드럼 내의 세탁물로 분사함에 있어서, 순환수 및 증기를 분사하는 분사구를 드럼 내에 각기 설치할 경우에 구조적으로 복잡하게 되므로 순환수 및 증기를 하나의 분사구를 통해 드럼 내의 세탁물로 분사하게 구성하는 것이 바람직하다.In spraying the circulating water and steam to the laundry in the drum, it is structurally complicated when the injection holes for circulating the circulating water and steam are respectively installed in the drum, so that the circulating water and steam are sprayed to the laundry in the drum through a single injection hole. It is preferable to construct.
상기 순환수 및 증기를 하나의 분사구를 통해 드럼 내의 세탁물로 분사할 경우에 순환수가 증기 발생기로 역류하거나 또는 증기가 순환수의 공급 통로로 역류하게 되므로 순환수 및 증기가 역류되지 않도록 해야 된다.When the circulating water and steam are sprayed to the laundry in the drum through a single injection port, the circulating water flows back to the steam generator or the steam flows back to the supply passage of the circulating water, so that the circulating water and the steam do not flow back.
그러므로 본 발명의 목적은 순환수 및 증기의 역류를 방지하면서 하나의 분사구를 통해 순환수 및 증기를 세탁물로 분사하는 드럼 세탁기의 순환수/증기 공급장치를 제공하는데 있다.It is therefore an object of the present invention to provide a circulating water / steam supply device of a drum washing machine for spraying circulating water and steam to laundry through a single injection port while preventing backflow of circulating water and steam.

이와 같이 구성된 본 발명의 드럼 세탁기의 순환수/증기 공급장치는 드럼(104) 내에 세탁물을 넣고, 세탁을 할 경우에 외부로부터 급수관(108)을 통해 물이 공급되고, 그 공급되는 물은 세제통(106)로 유입되어 세제와 혼합된 후 세탁수 공급관(110)을 통해 외조(102)로 유입된다.The circulating water / steam supply apparatus of the drum washing machine of the present invention configured as described above puts laundry into the drum 104, and when washing, water is supplied from the outside through the water supply pipe 108, and the supplied water is a detergent container ( 106 is introduced into the tub 102 through the washing water supply pipe 110 after being mixed with the detergent.
이와 같은 상태에서 모터(도면에 도시되지 않았음)를 구동시켜 드럼(104)을 회전시키고, 드럼(104)의 회전에 따라 세탁물이 회전되게 하면서 세탁물을 적시거나 또는 세탁을 수행할 경우에 순환펌프(118)가 구동되면서 외조(102) 내의 물을 순환수로 유입하고, 그 유입한 순환수는 순환수 공급관(122)을 통해 역류방지용 분지구(124)의 제 1 연결부(200)로 공급된다.In such a state, a motor (not shown in the drawing) is driven to rotate the drum 104, and the laundry is rotated according to the rotation of the drum 104 to wet the laundry or to perform a circulating pump when washing is performed. As the 118 is driven, the water in the outer tub 102 is introduced into the circulating water, and the introduced circulating water is supplied to the first connection part 200 of the backflow prevention branch 124 through the circulating water supply pipe 122. .
상기 제 1 유입구(200)로 공급된 순환수는 상기 순환펌프(118)가 펌핑하는 압력에 의해 격막(208)은 도 2에 점선으로 도시된 바와 같이 회전하면서 제 2 유입구(202)의 제 2 돌기부(212)에 밀착되므로 제 1 연결부(200)로 유입된 순환수는 순환수/증기 공급관(204)을 통과하고, 분사노즐(126)을 통해 세탁물로 분사되며, 제 2 연결부(202)로는 역류하지 않게 된다.The circulating water supplied to the first inlet 200 is rotated as shown by the dotted line in FIG. 2 by the pressure pumped by the circulation pump 118, so that the second of the second inlet 202 is rotated. Since it is in close contact with the protrusion 212, the circulating water introduced into the first connecting portion 200 passes through the circulating water / steam supply pipe 204, is injected into the laundry through the injection nozzle 126, and the second connecting portion 202 There is no backflow.
그리고 세탁물을 가열할 경우에 급수관(114)을 통해 유입되는 물을 증기 발생기(112)가 내장되어 있는 히터(도면에 도시되지 않았음)로 가열하여 증기를 발생하고, 발생한 증기는 증기 공급관(116)을 통해 역류방지용 분지구(124)의 제 2 연결부(202)로 유입된다.When the laundry is heated, the water flowing through the water supply pipe 114 is heated by a heater (not shown) in which the steam generator 112 is built to generate steam, and the generated steam is steam supply pipe 116. Inflow into the second connection portion 202 of the backflow prevention branch 124 through the ().
그러면, 역류방지용 분지구(124)는 제 2 연결부(202)로 유입되는 증기의 압력에 의해 격막(208)이 도 2에 실선으로 도시된 바와 같이 회전하여 제 1 연결부(200)의 제 1 돌기부(210)에 밀착되므로 제 2 연결부(202)로 유입된 증기는 순환수/증기 공급관(204)을 통과하고, 분사노즐(126)을 통해 세탁물로 분사되며, 제 1 연결부(200)로는 역류하지 않게 된다.Then, the backflow preventing branch 124 is rotated as shown in the solid line in the diaphragm 208 by the pressure of the steam flowing into the second connecting portion 202, the first protrusion of the first connecting portion 200 In close contact with the 210, the steam introduced into the second connection part 202 passes through the circulating water / steam supply pipe 204, is injected into the laundry through the injection nozzle 126, and does not flow back to the first connection part 200. Will not.
한편, 상기한 바와 같이 역류방지용 분지구(124)에 의해 역류되지 않고, 순환수/증기 공급관(204) 및 분사노즐(126)을 통해 분사되는 순환수 및 증기는 드럼(104) 내의 세탁물에 균일하게 분사되도록 해야 된다.Meanwhile, as described above, the circulating water and steam which are not flowed back by the backflow preventing branch 124 and are injected through the circulating water / steam supply pipe 204 and the injection nozzle 126 are uniform in the laundry in the drum 104. Should be sprayed.
상기 분사노즐(126)은 드럼(104) 내측의 전방 상부 중간에 위치하는 것으로서 분사노즐(126)에서 분사되는 순환수 및 증기의 분사각도를 여러 각도로 조절하면서 실험한 바, 90∼100°의 수평 분사각과, 수평으로부터 하부로 35∼40°의 수직 분사각을 가질 경우에 드럼(104)내의 세탁물에 균일하게 순환수 및 증기가 분사됨을 확인하였다.The injection nozzle 126 is located in the middle of the front upper part of the drum 104, and experimented while adjusting the injection angles of the circulating water and steam injected from the injection nozzle 126 at various angles. In the case of having a horizontal spray angle and a vertical spray angle of 35 to 40 degrees from the horizontal to the lower portion, it was confirmed that circulating water and steam were uniformly sprayed on the laundry in the drum 104.
