And a lift 8a for pulling up and dropping laundry as the drum 8 rotates, and a motor for rotating the drum 8 to be connected to the drum 8 at the rear of the tub 6. It comprises a (10).

아울러, 상기 드럼세탁기는 상기 터브(6)의 상측에 설치되어 상기 터브(6) 및 드럼(8) 내측으로 세탁수 및 세제를 공급하는 급수밸브 어셈블리(12)와 세제박스 어셈블리(14)와, 상기 터브(6)의 하측에 설치되어 상기 터브(6) 및 드럼(8) 내부의 세탁수를 배수시키는 배수펌프 어셈블리(16)가 더 포함된다.In addition, the drum washing machine is installed on the upper side of the tub (6) and the water supply valve assembly 12 and the detergent box assembly 14 for supplying the washing water and detergent to the tub 6 and the drum (8), A drain pump assembly 16 is installed below the tub 6 to drain the wash water inside the tub 6 and the drum 8.

여기서, 상기 드럼(8)은 내벽면에 다수개의 탈수공(8h)이 형성되어 세탁수가 상기 드럼(8)과 터브(6) 측으로 자유롭게 유동될 수 있을 뿐 아니라 탈수시 원심력에 의해 세탁물로부터 세탁수가 빠져나가도록 하고, 상기 급수밸브 어셈블리(12)와 배수펌프 어셈블리(14)는 각각 급수밸브(미도시)와 배수펌프(미도시)를 포함하도록 구성되어 각각 급수밸브와 배수펌프의 작동에 따라 세탁수를 급수하거나, 배수시키게 된다.Here, the drum 8 has a plurality of dehydration holes (8h) formed on the inner wall surface so that the washing water can flow freely to the drum (8) and the tub (6) side as well as wash water from the laundry by centrifugal force during dehydration The water supply valve assembly 12 and the drain pump assembly 14 are configured to include a water supply valve (not shown) and a drain pump (not shown), respectively, to be washed according to the operation of the water supply valve and the drain pump. Water or drain the water.

특히, 상기 터브(6)의 하부 측에는 상기 터브(6) 내측의 세탁수를 고온으로 가열하여 세탁 성능을 향상시킬 수 있도록 히터(20)가 장착되되, 상기 터브(6)는 상기 히터(20)가 장착될 수 있도록 하단에 히터 장착부(6a)가 하향 돌출되도록 형성된다.In particular, the lower side of the tub 6 is equipped with a heater 20 so as to improve the washing performance by heating the wash water inside the tub 6 to a high temperature, the tub 6 is the heater 20 Heater mounting portion (6a) is formed to protrude downward to the bottom so that it can be mounted.

상기와 같이 구성된 종래 기술의 동작을 살펴보면 다음과 같다.Looking at the operation of the prior art configured as described above are as follows.

먼저, 상기 드럼(8) 내부에 세탁물이 담겨진 상태에서 세탁 행정이 수행되면, 상기 급수밸브가 개방되도록 작동되어 세탁수가 상기 터브(5) 및 드럼(8) 내부로 급수되되, 세탁수는 상기 급수밸브 어셈블리(12)를 통과하여 상기 세제박스 어셈블리(14)를 통과하면서 세제와 함께 상기 터브(6) 내부로 공급되는데, 상기 터브(6) 내부에 세탁물의 포량에 따라 적정량의 세탁수가 공급된다.First, when a washing stroke is performed in a state in which laundry is contained in the drum 8, the water supply valve is operated to open to wash the water into the tub 5 and the drum 8, but the washing water is supplied to the water supply. Passing through the valve assembly 12 and the detergent box assembly 14 is supplied into the tub 6 with detergent, an appropriate amount of washing water is supplied to the tub 6 in accordance with the amount of laundry.

그리고, 상기 모터(10)가 작동되어 상기 드럼(8)이 회전됨에 따라 상기 리프트(8a)가 세탁물을 일정 높이까지 끌어올린 다음, 떨어지도록 하여 세탁물을 세탁하게 되는데, 사용자의 설정에 따라 상기 히터(20)가 작동되어 상기 터브(6) 내부의 세탁수를 가열하여 세탁 성능을 향상시킬 수도 있다.Then, the motor 10 is operated to rotate the drum 8, the lift 8a raises the laundry to a certain height, and then washes the laundry to fall, the heater according to the user's setting 20 may be operated to heat the washing water inside the tub 6 to improve washing performance.

상기와 같이 세탁 행정이 완료되면, 상기 배수펌프가 개방되도록 작동되어 세탁수를 배수시킨 다음, 상기 모터(10)가 고속으로 작동되어 상기 드럼(8)을 고속 회전시킴으로 원심력에 의해 세탁물로부터 세탁수가 빠져나가도록 하여 간헐 탈수가 진행되고, 다시 상기 급수밸브가 개방되도록 작동되어 세탁수가 급수되는 동시에 상기 드럼(8)이 회전되면서 헹굼 행정이 진행된다.When the washing stroke is completed as described above, the drainage pump is operated to drain the washing water, and then the motor 10 is operated at high speed to rotate the drum 8 at high speed so that the washing water from the laundry is centrifugal. Intermittent dehydration proceeds by exiting, and the water supply valve is opened again to supply washing water and at the same time the drum 8 rotates to rinse.

이와 같이, 헹굼 및 간헐 탈수가 반복적으로 작동된 다음, 마지막으로 탈수 행정이 진행되어 세탁이 완료된다.As such, rinsing and intermittent dehydration are repeatedly operated, and finally, the dehydration stroke is performed to complete the washing.

그러나, 종래의 드럼세탁기는 상기 급수밸브 어셈블리를 통과한 세탁수가 상기 세제박스 어셈블리(14)를 통과하면서 세제와 함께 상기 터브(6) 상측으로 공급된 다음, 상기 터브(6) 내측에 설치된 히터에 의해 가열되기 때문에 초기 급수시 차가운 세탁수가 급수됨에 따라 세탁물의 포 적심 속도가 늦어지는 문제점이 있다.However, in the conventional drum washing machine, the washing water passing through the water supply valve assembly is supplied to the upper side of the tub 6 together with the detergent while passing through the detergent box assembly 14, and then the heater is installed inside the tub 6. Since it is heated by the cold washing water during the initial water supply, there is a problem that the speed of lapping the laundry slows.

그리고, 종래의 드럼세탁기는 상기 터브(6) 내부의 세탁수를 가열하기 위한 히터(20)가 장착되도록 하기 위하여 하향 돌출되도록 히터 장착부(6a)가 형성되기 때문에 상기 터브(6)에 히터 장착부(6a)가 형성될 수 있는 별도의 공간이 요구되고, 상기 터브(6)로 세탁수가 급수되는 경우 상기 히터 장착부(6a)에도 세탁수가 담겨짐으로 세탁수가 낭비될 뿐 아니라 상기 히터 장착부(6a)에 세제가 잔류되어 세탁 성능을 떨어뜨리게 되는 문제점이 있다.In the conventional drum washing machine, since the heater mounting portion 6a is formed to protrude downward in order to mount the heater 20 for heating the washing water inside the tub 6, the heater mounting portion ( When a separate space for forming 6a) is required and the wash water is supplied to the tub 6, the washing water is also contained in the heater mounting portion 6a so that the washing water is wasted and the heater mounting portion 6a There is a problem that the detergent remains to degrade the washing performance.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 구조적으로 적정량의 세탁수가 급수되도록 하여 증기를 발생시켜 터브 및 드럼 내부로 분사되도록 함으로 포 적심 속도가 빨라질 뿐 아니라 살균 및 세탁 성능을 향상시킬 수 있는 증기분사식 드럼세탁기를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, structurally to ensure that the appropriate amount of washing water is supplied to generate steam to be sprayed into the tub and drum not only speed up the wetting, but also sterilization and washing performance The purpose is to provide a steam jet drum washing machine which can be improved.

다음, 상기 증기 발생장치(70)는 도 5 내지 도 7에 도시된 바와 같이 상기 제2급수유로(62c')와 증기유로(62d)가 상단에 연결되도록 설치되어 내부에 세탁수가 저장될 수 있는 공간이 형성된 밀폐형 압력용기(72)와, 상기 압력용기(72) 내부에 위치되도록 설치되어 세탁수를 가열시키는 히터(74)와, 상기 제2급수유로(62c')와 압력용기(72) 사이에 설치되어 세탁수의 급수를 조절하는 유입밸브(76a)와, 상기 증기유로(62d)와 압력용기(72) 사이에 설치되어 증기의 토출을 조절하는 토출밸브(76b)를 포함하여 구성된다.Next, the steam generator 70 is installed so that the second water supply passage 62c ′ and the steam passage 62d are connected to an upper end, as illustrated in FIGS. 5 to 7, in which washing water may be stored. A space is formed between the sealed pressure vessel 72, the heater 74 is installed so as to be located inside the pressure vessel 72 to heat the wash water, and between the second water supply passage 62c 'and the pressure vessel 72 And an inlet valve 76a installed at the water supply valve 76a for adjusting the water supply of the wash water, and a discharge valve 76b installed between the steam flow passage 62d and the pressure vessel 72 to control the discharge of steam.

이때, 상기 압력용기(72)는 수리 및 점검이 용이하도록 상기 터브(56)의 상측에 설치될 수도 있고, 설치 공간이 확보됨에 따라 상기 터브(56)의 하측에 설치될 수도 있다.At this time, the pressure vessel 72 may be installed on the upper side of the tub 56 to facilitate repair and inspection, or may be installed on the lower side of the tub 56 as the installation space is secured.

여기서, 상기 유입밸브(76a)와 토출밸브(76b)는 상기 압력용기(72) 내부의 압력에 따라 개폐를 조절하는 압력밸브인 것으로써, 상기 압력용기(72)의 상면에 위치되도록 설치되되, 상기 유입밸브(76a)는 상기 압력용기(72) 내부의 압력이 일정압력 미만인 경우 개방되고, 상기 토출밸브(76b)는 상기 압력용기(72) 내부의 압력이 일정압력 이상인 경우 개방되도록 전자적으로 조절되거나, 기구적으로 조절될 수 있다.Here, the inlet valve (76a) and the discharge valve (76b) is a pressure valve that controls the opening and closing according to the pressure inside the pressure vessel 72, is installed to be located on the upper surface of the pressure vessel (72), The inlet valve 76a is opened when the pressure inside the pressure vessel 72 is less than a predetermined pressure, and the discharge valve 76b is electronically controlled to open when the pressure inside the pressure vessel 72 is above a certain pressure. Or mechanically adjustable.

다음, 상기 증기 발생장치(70)는 상기 압력용기(72) 하부에 설치되어 상기 압력용기(72) 내부의 온도에 따라 상기 히터(74)의 작동을 조절하는 온도센서(78)와, 상기 히터(74)가 과열되는 것을 방지하기 위하여 상기 압력용기(72) 내부의 압력이 설정압력(Po) 이상인 경우 상기 히터(74)의 작동을 정지시키는 자동압력 스위치(79a)와, 상기 압력용기(72) 내부의 온도가 설정온도(To) 이상인 경우 상기 히터(74)의 작동을 정지시키는 자동온도 스위치(79b)가 더 포함된다.Next, the steam generator 70 is installed below the pressure vessel 72 to control the operation of the heater 74 according to the temperature inside the pressure vessel 72 and the heater Automatic pressure switch 79a for stopping the operation of the heater 74 when the pressure inside the pressure vessel 72 is greater than or equal to the set pressure Po in order to prevent overheating of the 74 and the pressure vessel 72. ) Is further included in the automatic temperature switch (79b) to stop the operation of the heater 74 when the temperature inside the set temperature (To) or more.

이때, 상기 히터(74)는 상기 압력용기(72)에 소정량의 세탁수만 급수되더라도 세탁수를 가열할 수 있도록 상기 압력용기(72)의 하부 측에 위치되도록 설치되는 전기히터인 것으로써, 상기 히터(74)가 과열되는 경우 증기가 과도하게 발생됨에 따라 상기 압력용기(72) 내부의 압력과 온도가 상승됨으로 상기 자동압력 스위치(79a) 및 자동온도 스위치(79b)가 작동되어 상기 히터(74)의 작동을 정지시키게 된다.In this case, the heater 74 is an electric heater which is installed to be located on the lower side of the pressure vessel 72 so as to heat the washing water even if only a predetermined amount of washing water is supplied to the pressure vessel 72, When the heater 74 is overheated, as the steam is excessively generated, the pressure and the temperature inside the pressure vessel 72 are increased, so that the automatic pressure switch 79a and the automatic temperature switch 79b are operated to operate the heater 74. ) Will stop working.

또한, 상기 증기 발생장치(70)는 상기 압력용기(72)를 통하여 외부로 열손실되는 것을 방지하기 위하여 상기 압력용기(72) 외둘레를 감싸도록 설치된 단열재(75)가 더 포함되어 구성된다.In addition, the steam generator 70 is configured to further include a heat insulating material 75 installed to surround the outer circumference of the pressure vessel 72 to prevent heat loss to the outside through the pressure vessel (72).

특히, 상기 증기 발생장치(70)는 상기 압력용기(72) 내부 상면에는 구조적으로 세탁수가 상기 압력용기에 일정 수위까지만 급수되도록 하는 에어 챔버(Airchamber : Ac)가 형성된다.In particular, the steam generator 70 is formed on the upper surface of the inside of the pressure vessel 72 is formed an air chamber (Airchamber: Ac) so that the washing water is supplied only to a certain level in the pressure vessel.

구체적으로, 상기 에어 챔버(Ac)는 도 7에 도시된 바와 같이 상기 압력용기(72) 내부 상면으로부터 일정수위까지 하향 돌출된 격자형 셀 형상으로 형성된 것으로써, 상기 히터(74)가 작동되어 증기가 발생됨에 따라 상기 압력용기(72) 내부에 일정 공간을 확보할 뿐 아니라 구조적으로 상기 압력용기(72) 내부에 일정수위 이상의 세탁수가 급수되지 않도록 한다.Specifically, as shown in FIG. 7, the air chamber Ac is formed in a lattice cell shape protruding downward from the upper surface of the pressure vessel 72 to a predetermined level, and the heater 74 is operated to vaporize. As it occurs, not only secures a predetermined space inside the pressure vessel 72, but also structurally prevents the washing water above a certain level from being supplied to the pressure vessel 72.

상기와 같이 상기 압력용기(72) 내부 상면에 상기 에어 챔버(Ac)가 형성되기 때문에 상기 유입밸브(76a)와 토출밸브(76b)가 개방된 상태에서 상기 압력용기(72) 내부로 세탁수가 급수될수록 상기 압력용기(72) 내부에 공기는 상기 토출밸브(76b)를 통하여 빠져나가게 되되, 상기 압력용기(72) 내부에 상기 에어 챔버(Ac) 하단 이상으로 세탁수가 급수되면, 상기 에어 챔버(Ac) 내부에 공기가 압축됨에 따라 구조적으로 일정 수위 이상으로 세탁수가 급수되지 않는다.Since the air chamber Ac is formed on the upper surface of the pressure vessel 72 as described above, the washing water is supplied into the pressure vessel 72 in the state where the inlet valve 76a and the discharge valve 76b are opened. Air is discharged through the discharge valve 76b in the pressure vessel 72 as much as possible, and when the wash water is supplied above the lower end of the air chamber Ac in the pressure vessel 72, the air chamber Ac ) As the air is compressed inside, the wash water is not supplied above a certain level.

이때, 상기 압력용기(72) 내부에 일정수위 이상으로 급수된 세탁수는 상기 토출밸브(76b) 및 증기유로(62d)를 통하여 상기 터브(56) 및 드럼(58) 내부로 유입되며, 설정된 급수시간 동안 이와 같이 급수를 행함으로써, 별도의 수위센서의 설치 없이 상기 압력용기(72) 내부의 수위를 마줄 수 있다. 여기서, 급수의 중단 여부는 급수시간을 미리 설정할 수도 있고, 상기 터브(56) 내부에 설치된 수위센서(미도시)를 이용할 수도 있다.At this time, the wash water supplied to the inside of the pressure vessel 72 by a predetermined level or more is introduced into the tub 56 and the drum 58 through the discharge valve 76b and the steam flow passage 62d, and the set water supply By supplying water in this way, the water level in the pressure vessel 72 can be reduced without installing a separate water level sensor. Here, whether or not to stop the water supply may be set in advance the water supply time, or may use a water level sensor (not shown) installed in the tub 56.

이와 같이, 상기 압력용기(72)의 수위를 맞춰주는 이유는 과도하게 압력용기(72) 내부에 세탁수가 급수되는 경우 상기 히터(74) 작동시 증기가 발생되어 저장될 수 있는 공간이 부족하여 상기 압력용기(72) 내부의 압력이 과도하게 상승할 위험이 있기 때문이다.As such, the reason for adjusting the water level of the pressure vessel 72 is that when the wash water is excessively supplied into the pressure vessel 72, steam is generated when the heater 74 is operated, and there is insufficient space to store the above. This is because there is a risk that the pressure inside the pressure vessel 72 rises excessively.

상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

먼저, 상기 드럼(58) 내부에 세탁물이 담겨진 상태에서 세탁 행정이 수행되면, 상기 급수밸브가 개방되도록 작동되어 세탁수가 상기 터브(56) 및 드럼(58) 내부로 급수되되, 세탁수는 상기 제1급수유로(62c)를 지나 상기 세제박스 어셈블리(62b)를 통과하면서 세제와 함께 상기 터브(56) 내부로 공급되는데, 상기 터브(56) 내부에 세탁물의 포량에 따라 적정량의 세탁수가 공급된다.First, when a washing stroke is performed in a state in which laundry is contained in the drum 58, the water supply valve is operated to open the washing water to supply water into the tub 56 and the drum 58, and the washing water is the first water. The first water supply passage 62c passes through the detergent box assembly 62b and is supplied into the tub 56 together with a detergent. The tub 56 is supplied with an appropriate amount of washing water in accordance with the amount of laundry.

아울러, 사용자가 설정에 따라 세탁수가 증기 분사되도록 조절되면, 세탁수는 상기 제2급수유로(62c')를 지나 상기 증기 발생장치(70)를 통과하면서 고온고압의 증기로 가열된 다음, 증기가 상기 증기유로(62d)를 지나 상기 터브(56) 및 드럼(58) 내부로 분사된다.In addition, when the user is adjusted to the steam spray according to the setting, the washing water is heated to a high temperature and high pressure steam while passing through the second water supply passage (62c ') and passing through the steam generating device 70, and then steam is The steam flow path 62d is injected into the tub 56 and the drum 58.

구체적으로, 상기 유입밸브(76a)와 토출밸브(76b)가 개방된 상태에서 상기 압력용기(72) 내부에는 세탁수가 급수되고, 상기 압력용기(72) 내부의 에어 챔버(Ac)에 의해 일정 수위까지만 세탁수가 급수된다.Specifically, in the state in which the inlet valve 76a and the discharge valve 76b are opened, the washing water is supplied to the inside of the pressure vessel 72, and the water level is constant by the air chamber Ac inside the pressure vessel 72. Only wash water is supplied.

즉, 상기 압력용기(72) 내부에 세탁수가 급수될수록 상기 압력용기(72) 내부에 공기는 상기 토출밸브(76b)를 통하여 빠져나가게 되고, 상기 에어 챔버(Ac)의 하단 이상으로 세탁수가 급수되면, 상기 에어 챔버(Ac) 내부에서 공기가 압축됨에 따라 세탁수가 일정 수위 이상으로 급수되지 않게 된다.That is, as the wash water is supplied into the pressure vessel 72, the air flows out of the pressure vessel 72 through the discharge valve 76b, and when the wash water is supplied above the lower end of the air chamber Ac. As the air is compressed in the air chamber Ac, the washing water is not supplied above a certain level.

다음, 상기 압력용기(72) 내부에 일정 수위까지 세탁수가 급수되면, 상기 유입밸브(76a)와 토출밸브(76b)가 닫힘되는 동시에 상기 히터(74)가 작동되어 세탁수를 가열하여 고온고압의 증기가 발생시킨다.Next, when the wash water is supplied to a predetermined level in the pressure vessel 72, the inflow valve 76a and the discharge valve 76b are closed, and the heater 74 is operated to heat the wash water to obtain a high temperature and high pressure. Steam is generated.

이때, 상기 압력용기(72) 내부로 세탁수가 급수될수록 상기 에어 챔버(Ac)에 의해 일정 수위까지만 세탁수가 급수되고, 그 이상으로 공급되는 세탁수는 상기 토출밸브(76b) 및 증기유로(62d)를 따라 상기 터브(56) 및 드럼(58) 내부로 유입되어 세탁시 사용되며, 급수가 완료되면 상기 유입밸브(76a)와 토출밸브(76b)가 닫힘되도록 작동되고, 상기 히터를 작동시키게 된다.At this time, the washing water is supplied only to a predetermined level by the air chamber Ac as the washing water is supplied into the pressure vessel 72, and the washing water supplied above the discharge valve 76b and the steam flow path 62d. The tub 56 and the drum 58 are introduced into the tub 56 and used for washing, and when the water supply is completed, the inlet valve 76a and the discharge valve 76b are closed to operate, and the heater is operated.

아울러, 상기 온도센서(78)가 상기 압력용기(72) 내부의 온도를 측정하고, 그에 따라 상기 히터(74)의 작동을 조절하여 상기 히터(74)가 과열되지 않도록 한다.In addition, the temperature sensor 78 measures the temperature inside the pressure vessel 72, thereby adjusting the operation of the heater 74 so that the heater 74 is not overheated.

또한, 상기 온도센서(78)가 고장나거나, 이상 작동될 경우, 상기 자동압력 스위치(79a) 및 자동온도 스위치(79b)가 작동되어 상기 히터(74) 측으로 공급되는 전원을 차단하여 상기 히터(74)가 과열되는 것을 방지할 수 있다.In addition, when the temperature sensor 78 is broken or abnormally operated, the automatic pressure switch 79a and the automatic temperature switch 79b are operated to cut off the power supplied to the heater 74 to the heater 74. ) Can be prevented from overheating.

다음, 상기 히터(74)가 작동됨에 따라 밀폐된 압력용기(72) 내부에 세탁수는 끓게되어 고온고압의 증기가 발생되고, 상기 압력용기(72) 내부의 온도가 상기 온도센서(78)에 의해 적정온도 이상이 되면, 상기 토출밸브(76b)가 개방되어 증기가 상기 증기유로(62d)를 따라 상기 터브(56) 및 드럼(58) 내부로 분사됨으로 세탁물에 포 적심이 보다 신속하게 진행된다.Next, as the heater 74 is operated, the washing water is boiled in the sealed pressure vessel 72 to generate high temperature and high pressure steam, and the temperature inside the pressure vessel 72 is applied to the temperature sensor 78. When the temperature is higher than the proper temperature, the discharge valve 76b is opened, and steam is injected into the tub 56 and the drum 58 along the steam flow path 62d so that the laundry can be loaded faster. .

상기와 같이 상기 터브(56) 및 드럼(58) 내부에 적정량의 세탁수가 급수되면, 상기 급수밸브가 닫힘되고, 상기 모터(60)가 작동되어 상기 드럼(58)이 회전됨에 따라 상기 리프트(58a)가 세탁물을 일정 높이까지 끌어올린 다음, 떨어지도록 하여 세탁 행정이 수행된다.When the appropriate amount of washing water is supplied to the tub 56 and the drum 58 as described above, the water supply valve is closed, and the motor 60 is operated to rotate the drum 58, thereby lifting the lift 58a. The washing stroke is carried out by raising the laundry to a certain height and then dropping it.

이와 같이 세탁 행정이 완료되면, 상기 배수펌프가 개방되도록 작동되어 세탁수를 배수시킨 다음, 상기 모터(60)가 고속으로 작동되어 상기 드럼(58)을 고속 회전시킴으로 원심력에 의해 세탁물로부터 세탁수가 빠져나가도록 하여 간헐 탈수가 진행되고, 다시 상기 급수밸브가 개방되도록 작동되어 세탁수가 급수되는 동시에 상기 드럼(58)이 회전되면서 헹굼 행정이 진행된다.When the washing stroke is completed as described above, the drainage pump is operated to drain the washing water, and then the motor 60 is operated at high speed to rotate the drum 58 at high speed so that the washing water is removed from the laundry by centrifugal force. Intermittent dehydration proceeds by going out, and the water supply valve is opened again to supply washing water and at the same time the drum 58 is rotated to rinse.

다음, 상기와 같이 헹굼 및 간헐 탈수가 반복적으로 작동된 다음, 마지막으로 탈수 행정이 진행되어 세탁이 완료된다.Next, rinsing and intermittent dehydration are repeatedly operated as described above, and finally, a dehydration stroke is performed to complete washing.

물론, 세탁 및 헹굼 행정시에도 초기 급수시와 마찬가지로 사용자의 설정에 따라 세탁수가 상기 증기 발생장치(70)를 통과하여 고온고압의 증기가 되어 상기 터브(56) 및 드럼(58) 내부로 분사되도록 하여 살균 및 세탁 성능을 향상시킬 수 있다.Of course, in the washing and rinsing stroke, the washing water passes through the steam generator 70 and becomes a high-temperature, high-pressure steam, as in the case of initial water supply, to be sprayed into the tub 56 and the drum 58 according to the user's setting. This can improve sterilization and washing performance.

상기와 같이 구성되는 본 발명에 따른 증기분사식 드럼세탁기는 세탁수가 증기 발생장치를 통과하면서 가열되어 고온고압의 증기 형태로 터브 및 드럼 내부로 급수되기 때문에 초기 급수시 세탁물의 포 적심이 신속하게 이루어짐으로 물과 전기 에너지를 절약할 수 있고, 세탁 및 헹굼시 고온고압의 증기 형태로 세탁수가 급수되도록 함으로 살균 및 세탁 성능을 향상시킬 수 있는 이점이 있다.The steam jet drum washing machine according to the present invention configured as described above is heated while passing through the steam generator, so that water is fed into the tub and drum in the form of a high-temperature, high-pressure steam, so that the washing of the laundry is performed quickly during initial water supply. It is possible to save water and electrical energy, and to wash and rinse the water in the form of high temperature and high pressure steam during washing and rinsing, thereby improving the sterilization and washing performance.

또한, 본 발명에 따른 증기분사식 드럼세탁기는 상기 증기 발생장치 내부에 에어 챔버가 형성됨으로 구조적으로 압력용기 내부에 적정량의 세탁수가 급수되도록 하여 안정된 수위 제어가 가능함으로 제품의 신뢰성을 확보할 수 있고, 상기 압력용기에 별도의 수위센서를 장착하지 않아도 됨으로 구조가 간단해질 뿐 아니라 생산비용이 절감되는 이점이 있다.In addition, the steam jet drum washing machine according to the present invention can ensure the reliability of the product by allowing the stable water level control by allowing the appropriate amount of washing water to be supplied to the internal structure of the pressure vessel because the air chamber is formed inside the steam generator, Since the pressure vessel does not have to be equipped with a separate level sensor, not only the structure is simple but also there is an advantage that the production cost is reduced.
