본 발명은 증기분사식 드럼세탁기에 관한 것으로, 보다 상세하게는 드럼세탁기의 급수밸브를 통해 공급된 물을 가열에 의해 증기로 변환시키는 증기발생장치를 드럼세탁기에 장착하여, 급속 또는 연속적으로 증기를 발생시켜 세탁기에 공급할 수 있도록 한 드럼세탁기에 관한 것이다.The present invention relates to a steam jet drum washing machine, and more particularly, to a steam washing machine equipped with a steam generator for converting water supplied through a drum washing machine's water supply valve into steam by heating, to generate steam rapidly or continuously. It relates to a drum washing machine that can be supplied to the washing machine.
일반적으로, 세탁기는 세탁, 헹굼 및 탈수행정을 수행하여 세탁물을 세탁하는 기계장치로서, 세탁방식에 따라 펄세이터식, 교반식, 드럼식 등으로 구분된다. In general, a washing machine is a machine for washing laundry by performing washing, rinsing, and dehydrating strokes. The washing machine is classified into a pulsator type, a stirring type, a drum type, and the like according to a washing method.
최근, 세탁기는 세탁 성능뿐만 아니라, 사용의 편리성이 매우 중요한 제품 구매 요소가 되고 있으며, 이에 따라 사용의 편리성을 증대시키기 위한 제품 개발이 가속화되고 있다.Recently, a washing machine has become an important purchase factor for not only washing performance but also convenience of use, and thus, product development for increasing convenience of use has been accelerated.
따라서, 드럼 세탁기는 사용의 편리한 세탁기로 최근 판매가 급증되고 있고, 더욱 성능이 우수하도록 개발이 촉진되고 있다.Therefore, the drum washing machine has recently been rapidly increasing as a convenient washing machine, and the development has been promoted to further improve the performance.
도 1은 종래 기술에 따른 드럼 세탁기의 개략적인 단면도로서, 드럼 세탁기(1)는 세탁물을 세탁하기 위해 내면에 다수개의 리프트(5)를 형성하고 있는 드럼(4)과; 상기 드럼(4)을 회전시키기 위해 상기 드럼(4)에 결합되는 회전축(3)과; 상기 회전축(3)으로 회전력을 풀리를 통해 전달하는 모터(6)와; 상기 드럼(4) 외측으로 결합되는 터브(2)로 구성된다.1 is a schematic cross-sectional view of a drum washing machine according to the prior art, wherein the drum washing machine 1 includes a drum 4 having a plurality of lifts 5 formed therein for washing laundry; A rotating shaft (3) coupled to the drum (4) for rotating the drum (4); A motor (6) for transmitting rotational force to the rotary shaft (3) through a pulley; It consists of a tub (2) coupled to the drum (4) outside.
이렇게 구성된 드럼세탁기의 동작방법은, 먼저, 드럼 세탁기(1)의 드럼(4)에 세탁물을 투입한 후, 시작버튼을 누르면 급수가 되고, 동시에 모터(6)에 전원이 인가된다.In the operation method of the drum washing machine configured as described above, first, laundry is put into the drum 4 of the drum washing machine 1, and when the start button is pressed, water is supplied and power is applied to the motor 6 at the same time.
그리고, 상기 모터(6)에 전원이 인가되면 모터(6)는 회전을 하게 되고, 모터의 회전력은 풀리와 밸트에 의한 전동시스템에 의해 상기 회전축(3)까지 도달되면서 상기 회전축(3)을 회전시키게 된다.Then, when power is applied to the motor 6, the motor 6 rotates, and the rotational force of the motor rotates the rotary shaft 3 while reaching the rotary shaft 3 by an electric system by a pulley and a belt. Let's go.
또한, 상기 회전축(3)의 회전은 상기 드럼(4)을 정, 역회전시키기 때문에, 상기 드럼(4) 내부의 세탁물을 세탁할 수 있게 된다.In addition, since the rotation of the rotating shaft 3 rotates the drum 4 forward and reverse, the laundry inside the drum 4 can be washed.
그리고, 상기 드럼(4) 내면에 형성된 다수개의 리프트(5)에 의해 세탁물이 들려졌다가 떨어지면서 낙차에 의한 충격력과 굴신에 의해 세탁이 이루어진다.Then, the laundry is lifted and dropped by the plurality of lifts 5 formed on the inner surface of the drum 4, and washing is performed by impact force and flexion caused by a drop.
이러한, 드럼 세탁 방식은 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서, 모터의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 포손상이 거의 없고, 세탁물이 서로 엉키지 않으며, 두드리고 비벼 빠는 세탁효과를 낼 수 있으나, 세탁물의 투입 및 인출에 있어 불편함이 있어 이를 개선하기 위한 기술 개발이 이루어지고 있다.Such a drum washing method is a method in which washing is performed using a friction force of a rotating drum and a laundry by receiving a driving force of a motor in a state in which detergent, washing water, and laundry are put in a drum, and there is almost no damage to laundry. This is not tangled with each other, but can be washed and rubbed wash effect, but there is an inconvenience in the input and withdrawal of the laundry has been made technology development to improve this.
그러나, 종래의 드럼 세탁기의 경우, 터브(2) 하부에 세탁수 가열용 전기 히터가 위치하기 위한 기본 공간이 있음으로 해서 세탁 중 잔류 세제가 모이기 쉽고, 그 공간만큼 물이 항상 낭비되는 측면이 있다.However, in the conventional drum washing machine, since there is a basic space for placing the electric heater for heating the washing water under the tub 2, residual detergent tends to collect during washing, and water is always wasted as much as the space. .
또한, 급수시 텀블링(Tumbling)에 의한 포 적심으로 포젖는 속도가 늦는다는 단점이 있다.In addition, there is a disadvantage in that the wetting speed is slow due to the foaming due to tumbling during water supply.
이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로, 드럼세탁기의 급수부로부터 공급되는 물을 증기로 변환시켜 드럼 내부로 공급함으로써 소량의 세탁수를 가지고 포 적심 효과를 극대화할 수 있는 증기세탁기용 증기발생장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in order to solve the problems as described above, by converting the water supplied from the water supply of the drum washing machine into steam to supply the inside of the drum with a small amount of wash water can maximize the effect of wetting It is an object of the present invention to provide a steam generator for a steam washing machine.

Here, the steam generator 40 is connected to the water supply valve (not shown) by the water supply passage 62 to receive water, and is connected to the backflow prevention branch device 30 by the steam supply pipe 63.
이렇게 구성된 드럼세탁기는 제어장치에서 소비자가 증기 세탁 동작 버튼을 누르면, 세탁기의 급수 밸브(미도시)가 개방되어 급수관(61)을 통해 세제박스(50)내로 세탁수가 공급되고, 세제박스(50)의 세제와 함께 세탁에 필요한 소정의 수위까지 급수가 이루어진다. 급수가 완료되면 급수 밸브가 닫히고, 순환펌프(21)가 동작된다.The drum washing machine configured as described above, when the consumer presses the steam washing operation button in the control device, a water supply valve (not shown) of the washing machine is opened to supply washing water to the detergent box 50 through the water supply pipe 61, and the detergent box 50. Along with the detergent, water is supplied to a predetermined level for washing. When the water supply is completed, the water supply valve is closed and the circulation pump 21 is operated.
여기서, 세제를 용해하기 위해 기설정된 시간동안 물순환이 이루어지며 순환이 종료된 후, 증기발생장치(40)로 공급된 물은 가열에 의해 증기로 변환된다.Here, the water circulation is made for a predetermined time to dissolve the detergent, and after the circulation is completed, the water supplied to the steam generator 40 is converted to steam by heating.
상기 증기발생장치(40)에서 발생된 증기는 분사노즐(31)을 통하여 세탁기의 드럼(10) 내부로 분사되게 된다.The steam generated by the steam generator 40 is injected into the drum 10 of the washing machine through the injection nozzle 31.
따라서, 드럼(10)에서는 세제가 용해된 세탁수와 증기에 의해 세탁물이 세탁된다.Therefore, in the drum 10, laundry is washed by washing water and steam in which detergent is dissolved.
도 3은 본 발명에 따른 증기 발생 장치의 구성도로서, 일측에 상기 급수유로(62)를 통해 물이 공급되는 급수관(171)이 형성되어 있고, 타측에 상기 증기공급관(63)이 연결되어 증기가 배출되는 증기 배출관(131)이 형성되어 있는 용기(300)와; 상기 용기(300) 외부에 감겨져 있는 인덕션 코일(193)과; 상기 인덕션 코일(193)에 고주파 전류를 공급하는 인버터(250)와; 상기 용기(300) 내부에 장착되어, 상기 인덕션 코일(193)에 공급되는 고주파 전류에 의해 발열하여 상기 급수관(171)으로 인입되는 물을 증발시키는 열매체(185)로 구성된다.3 is a configuration diagram of a steam generating device according to the present invention, wherein a water supply pipe 171 through which the water is supplied through the water supply passage 62 is formed on one side, and the steam supply pipe 63 is connected to the other side to supply steam. The container 300 is formed with a steam discharge pipe 131 is discharged; An induction coil 193 wound around the outside of the container 300; An inverter 250 for supplying a high frequency current to the induction coil 193; The heat medium 185 is installed inside the container 300 and generates heat by a high frequency current supplied to the induction coil 193 to evaporate water introduced into the water supply pipe 171.
상기 용기(300)에 도면에 도시된 것처럼, 상기 급수관(171) 및 증기 배출관(131) 보다 단면적이 넓게 형성됨이 바람직하다. As shown in the drawing, the container 300 has a larger cross-sectional area than the water supply pipe 171 and the steam discharge pipe 131.
이렇게 구성된 본 발명의 증기 발생 장치는 소비자가 스팀 세탁 동작 버튼을 누르면, 세탁기의 급수 밸브가 개방되어, 상기 급수유로(62)를 통해 물이 공급되고, 공급된 물은 상기 급수관(171)을 통하여 용기(300) 내로 유입된다. 이와 동시에, 인버터(250)에 전원이 온(On)된다.In the steam generator of the present invention configured as described above, when a consumer presses a steam washing operation button, a water supply valve of a washing machine is opened, and water is supplied through the water supply passage 62, and the supplied water is supplied through the water supply pipe 171.
