Description

펄세이터방식 건조세탁기{Pulsator type washing machine having drying function}Pulsator type washing machine having drying function}

본 발명은 펄세이터방식 건조세탁기에 관한 것으로서, 보다 상세하게는 내조에 가열공기를 효과적으로 분사함으로써 세탁물을 건조하는 기능을 향상시킬 수 있는 펄세이터방식 세탁기에 관한 것이다.The present invention relates to a pulsator type dry washing machine, and more particularly, to a pulsator type washing machine capable of improving the function of drying laundry by spraying heated air to the inner tank effectively.

세탁기는 세탁물에 충격 등의 에너지를 가하여 오염물을 박리시키는 장치로서, 세탁물에 에너지를 가하는 방식에 따라 펄세이터방식 세탁기, 드럼방식 세탁기 및 애지테이터방식 세탁기로 나눌 수 있다. 즉 펄세이터 또는 애지테이터에 의하여 세탁물에 충격을 주거나, 드럼의 회전에 의하여 세탁물을 낙하시켜 세탁물에 충격을 주어 세탁물을 세탁한다. 그리고 여기에 세제의 작용이 추가되어 세탁이 이루어진다.A washing machine is a device that peels contaminants by applying energy such as impact to laundry, and may be divided into a pulsator type washing machine, a drum type washing machine, and an agitator type washing machine according to a method of applying energy to laundry. That is, the laundry is impacted by a pulsator or agitator, or the laundry is dropped by dropping the laundry by the rotation of the drum to wash the laundry. And the action of the detergent is added to this is done washing.

상술한 세탁기들은 의류 등과 같은 세탁물을 세탁하는 기능만을 가지는 것이 일반적이다. 따라서, 세탁기의 사용자는 세탁 완료후에 세탁물을 세탁기에서 꺼내어 햇볕에서 건조시켜야 한다.The above-mentioned washing machines generally have only a function of washing laundry such as clothes. Therefore, the user of the washing machine should take out the laundry from the washing machine after the washing is completed and dry it in the sun.

근래에는 아파트에서의 생활이 널리 보급되고 또한 생활 패턴의 변화로 세탁 완료된 세탁물을 빠른 시간내에 인공적으로 건조시킬 수 있는 것이 요구되었고, 이러한 요구에 부응하여 건조기가 개발되었다. 건조기가 개발됨으로써 세탁기에서 세탁 완료된 세탁물을 간단히 그리고 빠른 시간내에 건조시키는 것이 가능하다.In recent years, it has been required to be able to artificially dry laundry which has been widely washed in the apartments in a short time due to the widespread use of apartments and changes in living patterns, and a dryer has been developed in response to this demand. The development of a dryer makes it possible to dry laundry which has been washed in a washing machine simply and quickly.

그러나, 통상 건조기는 세탁기와 거의 같은 크기이므로 세탁기와 건조기를 각각 설치하려면 많은 공간을 차지하게 되며, 세탁기에서 세탁 완료된 세탁물을 세탁기에서 꺼내어 다시 건조기에 넣어야 하므로 사용이 불편하다는 단점이 있었다.However, in general, a dryer is almost the same size as a washing machine, and therefore, it takes up a lot of space to install each of the washing machine and the dryer, and it is inconvenient to use the laundry having to be removed from the washing machine and put back into the dryer.

따라서, 건조기능을 갖는 세탁기의 개발이 요구되었다. 이에 따라, 드럼방식세탁기에서는 세탁 완료 후에 세탁된 세탁물들을 이동시키지 않고 드럼에서 바로 건조시킬 수 있는 건조기능를 가지는 세탁기가 제안되었다. 그러나, 일반적으로 세탁 능력이 드럼방식보다 양호한 펄세이터방식이나 애지테이터방식의 세탁기에서는 건조기능을 갖지 못하였다.Therefore, the development of a washing machine having a drying function has been required. Accordingly, in the drum type washing machine, a washing machine having a drying function capable of drying directly from a drum without moving laundry after completion of washing has been proposed. In general, however, the washing machine of the pulsator type or agitator type washing machine having a better washing capacity than the drum type has no drying function.

따라서, 세탁능력이 양호하면서도 동시에 세탁물의 건조가 가능한 펄세이터방식의 세탁기의 개발이 요구되었다.Therefore, there has been a demand for the development of a pulsator type washing machine having good washing ability and capable of drying laundry.

상술한 문제점을 해결하기 위하여, 본 발명의 목적은 세탁기능이 양호하고, 또한 가열공기를 효과적으로 내조에 분사시켜 세탁물의 건조효율이 높은 펄세이터방식 건조세탁기를 제공하는 것이다.In order to solve the above-mentioned problems, an object of the present invention is to provide a pulsator type dry washing machine having a good washing function, and also effectively spraying heated air into the inner tank to increase the drying efficiency of the laundry.

또한, 상기 분사노즐의 양단부는 상기 내조의 내벽 방향으로 경사지게 형성되는 것이 더욱 바람직하다.In addition, both ends of the injection nozzle is more preferably formed to be inclined in the inner wall direction of the inner tank.

따라서, 본 발명에 따르면, 세탁 효율이 우수하게 세탁물을 세탁하고, 또한 보다 효과적으로 세탁된 세탁물을 세탁기에서 바로 건조시키는 것이 가능하게 된다.Therefore, according to the present invention, it is possible to wash the laundry with excellent washing efficiency and to dry the washed laundry more effectively directly in the washing machine.

이하, 첨부 도면을 참조하여, 본 발명에 따른 펄세이터방식 건조세탁기의 바람직한 실시예를 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the pulsator type dry washing machine according to the present invention will be described.

도 1을 참조하여, 본 발명에 따른 펄세이터방식 건조세탁기를 설명하면 다음과 같다.Referring to Figure 1, when describing the pulsator type dry washing machine according to the present invention.

먼저, 세탁물을 세탁하는 세탁 기능을 위한 구성부품들을 설명하면 다음과 같다.First, the components for the washing function for washing laundry will be described as follows.

세탁기 케이스(1)의 내부에는 세탁수를 저장하는 외조(3)가 설치되며, 상기 외조(3)의 내부에는 다수의 통공(5a)이 형성된 내조(5)가 회전 가능하게 설치되며, 상기 내조(5)의 내부에는 펄세이터(7)가 회전 가능하게 설치된다. 그리고, 내조(5) 및 펄세이터(7)는 외조(3)의 저면에 설치된 구동수단(9)에 의하여 회전하게 된다.An inner tub 3 for storing the washing water is installed in the washing machine case 1, and an inner tub 5 in which a plurality of through holes 5a are formed is rotatably installed in the tub 3. The pulsator 7 is rotatably installed in the inside of (5). And the inner tank 5 and the pulsator 7 are rotated by the drive means 9 provided in the bottom face of the outer tank 3.

한편, 케이스(1)의 상부에는 세탁 및 헹굼을 위한 물을 공급하는 급수밸브(10)가 설치되며, 상기 급수밸브(10)에는 내조(5)로 물을 공급하는 급수덕트(미도시)가 연결된다. 그리고, 외조(3)의 저면에는 세탁 완료 후의 더러워진 세탁수를 세탁기의 외부로 배출시키기 위한 배수덕트(11)가 연결되며, 상기 배수덕트(11)의 소정위치에는 배수밸브(13)가 설치된다.On the other hand, the upper part of the case 1 is provided with a water supply valve 10 for supplying water for washing and rinsing, the water supply valve 10 is a water supply duct (not shown) for supplying water to the inner tank (5) Connected. A drain duct 11 for discharging the dirty laundry water after the completion of washing to the outside of the washing machine is connected to the bottom of the outer tub 3, and a drain valve 13 is installed at a predetermined position of the drain duct 11. .

다음으로, 세탁물의 건조를 위한 구성부품들을 설명한다.Next, the components for drying the laundry will be described.

외조(3)와 케이스(1)의 사이에는 내조(5)에 세탁물을 건조시키기 위한 가열된 공기를 공급하는 순환덕트(20)가 설치된다. 즉, 상기 순환덕트(20)의 하단은 외조(3)의 하단에 연결되며, 상단은 내조(5)의 상부 근처에 위치하게 된다.Between the outer tub 3 and the case 1, a circulation duct 20 for supplying heated air for drying the laundry to the inner tub 5 is installed. That is, the lower end of the circulation duct 20 is connected to the lower end of the outer tank 3, the upper end is located near the upper portion of the inner tank (5).

물론, 상기 순환덕트(20)의 소정 위치에는 공기를 가열하기 위한 히터(15)와, 공기를 강제로 순환시키기 위한 송풍팬(22)이 설치된다. 여기서, 히터(15)는 송풍팬(22)의 전방(순환덕트의 토출구방향)에 설치되는 것이 바람직하다.Of course, a predetermined position of the circulation duct 20 is provided with a heater 15 for heating the air and a blowing fan 22 for forcibly circulating the air. Here, it is preferable that the heater 15 is provided in front of the blowing fan 22 (the discharge port direction of the circulation duct).

한편, 순환덕트(20)의 토출구에서 토출되어 내조(5)에 있는 의류를 건조시키고 다시 순환덕트(20)로 배출되는 공기는 다습한 상태이다. 따라서, 이러한 다습한 상태의 공기를 그대로 순환시키게 되면 건조효율이 저하되므로 공기의 순환시에 공기가 함유하고 있는 습기를 제거하여야 한다. 즉, 상기 히터(15)가 일부 제습기능를 수행하지만 별도의 제습장치를 설치하는 것도 물론 가능하다.On the other hand, the air discharged from the discharge port of the circulation duct 20 to dry the clothes in the inner tank 5 and discharged again to the circulation duct 20 is in a humid state. Therefore, when the air in such a humid state is circulated as it is, the drying efficiency is lowered. Therefore, the moisture contained in the air must be removed during the air circulation. That is, the heater 15 performs some dehumidification functions, but it is of course possible to install a separate dehumidification device.

한편, 건조과정시에 내조(5)의 내부에 있는 세탁물을 보다 효과적으로 건조시키기 위하여 내조(5)에 가열공기를 효과적으로 공급하는 것이 바람직하다. 이를 도 2를 참조하여 설명하면 다음과 같다.On the other hand, it is preferable to effectively supply the heating air to the inner tank 5 in order to dry the laundry inside the inner tank 5 more effectively during the drying process. This will be described with reference to FIG. 2.

순환덕트(20)의 선단에는 가열공기를 내조에 분사하는 분사노즐(24)이 설치된다. 상기 분사노즐(24)은 외조커버(50)를 관통하여 내조(5) 내부에 설치되는 것이 바람직하다. 또한, 상기 분사노즐(24)의 저면에는 다수의 분사공(24a)이 형성되어, 가열공기를 여러방향으로 분사시켜 주는 것이 바람직하다.At the tip of the circulation duct 20, an injection nozzle 24 for injecting heated air into the inner tank is provided. The injection nozzle 24 is preferably installed in the inner tank 5 through the outer tank cover 50. In addition, it is preferable that a plurality of injection holes 24a are formed at the bottom of the injection nozzle 24 to inject the heating air in various directions.

한편, 상기 분사노즐(24)는 순환덕트(20)의 선단에서 회전 가능하게 설치되는 것이 바람직하다. 왜냐하면, 이렇게 구성함으로써 내조(5)에 분사되는 가열공기를 회전시켜 보다 효율적으로 세탁물을 건조시킬 수 있기 때문이다.On the other hand, the injection nozzle 24 is preferably rotatably installed at the tip of the circulation duct (20). This is because by such a configuration, the laundry can be dried more efficiently by rotating the heated air injected into the inner tank 5.

한편, 본 실시예에서는 상부가 좁고 하부가 넓은 형상의 분사노즐(24)를 도시 및 설명하였으나 본 발명은 이에 한정되지 않는다. 즉, 상기 분사노즐의 형상은 내조(5)에서의 가열공기의 흐름 등을 감안하여 소정 형상으로 변형하여 사용하는 것도 물론 가능하다. 예를 들어, 도 3에 도시한 바와 같이, 상기 분사노즐(24)을 상기 내조(5)의 내벽 방향으로 경사지게 형성하여 가열공기를 통상 세탁물이 몰려 있는 내조(5)의 벽면 방향으로 가열공기를 집중시키는 것도 가능하다. 또한, 분사노즐의 양단부를 내조(5) 방향으로 돌출되도록 연장시켜 가열공기를 내조(5)의 벽면 방향으로 집중시키는 것도 가능하다.Meanwhile, in the present embodiment, the injection nozzle 24 having a narrow upper portion and a wider lower portion is illustrated and described, but the present invention is not limited thereto. That is, the shape of the injection nozzle may be used after being deformed into a predetermined shape in consideration of the flow of the heating air in the inner tank 5. For example, as shown in FIG. 3, the spray nozzle 24 is formed to be inclined in the inner wall direction of the inner tank 5 so that the heating air is heated in the wall direction of the inner tank 5 in which laundry is normally collected. It is also possible to concentrate. It is also possible to extend both ends of the injection nozzle so as to protrude in the direction of the inner tank 5 to concentrate the heating air in the wall surface direction of the inner tank 5.

상술한 본 발명에 따른 펄세이터방식 건조세탁기의 작동을 설명하면 다음과 같다.Referring to the operation of the pulsator type dry washing machine according to the present invention described above is as follows.

먼저, 세탁기능을 설명하면 다음과 같다. 세탁기능은 종래의 세탁기의 동작과 실질적으로 동일하다. 즉, 세탁행정, 헹굼행정 및 탈수행정이 순차적으로 행해져 세탁물을 세탁하게 된다.First, the washing function will be described as follows. The washing function is substantially the same as the operation of a conventional washing machine. That is, the washing stroke, the rinsing stroke and the dehydrating stroke are sequentially performed to wash the laundry.

세탁과 탈수가 완료되면 건조과정이 시작된다. 건조과정이 시작되면 송풍팬(22)이 동작하게 되어 내조(5) 내부의 공기가 순환덕트(20)를 순환하여 다시 내조(5)로 공급된다. 이때, 공기는 히터(15)에 의하여 가열되어 내조(5)로 공급되게 된다. 내조(5)로 공급된 가열공기는 세탁물과 열교환하여 세탁물을 건조시키게 된다.The drying process begins when washing and dehydration are complete. When the drying process is started, the blowing fan 22 is operated so that the air inside the inner tank 5 circulates through the circulation duct 20 and is supplied to the inner tank 5 again. At this time, the air is heated by the heater 15 is supplied to the inner tank (5). The heated air supplied to the inner tank 5 exchanges heat with the laundry to dry the laundry.

즉, 가열된 공기가 내조(5)를 순환하면서 내조(5)내의 세탁물을 건조시키게되고, 소정 시간의 순환 과정 후에 건조과정이 완료되게 된다.That is, the heated air circulates the inner tank 5 to dry the laundry in the inner tank 5, and the drying process is completed after a predetermined time cycle.

한편, 세탁물은 통상 탈수 완료후에 내조(5)의 벽면에 부착되어 있게 된다. 그런데, 본 발명에서는 가열공기가 다수의 분사공(24a)에서 분사되며, 또한 상기 분사노즐(24)이 회전하면서 가열공기를 분사한다. 또한, 가열공기를 세탁물이 몰려있는 내조(5)의 벽면 방향으로 집중적으로 분사시키는 것이 가능하다. 따라서, 가열공기가 세탁물을 보다 효과적으로 건조시키게 된다.On the other hand, laundry is normally attached to the wall surface of the inner tank 5 after completion of dehydration. However, in the present invention, heated air is injected from the plurality of injection holes 24a, and the injection nozzle 24 rotates to inject the heating air. In addition, it is possible to intensively spray the heated air in the direction of the wall surface of the inner tank 5 in which laundry is collected. Thus, the heated air will dry the laundry more effectively.

상기에서 본 발명은 하나의 실시예만을 설명하였으나, 첨부된 청구범위에서 알 수 있는 바와 같이 본 발명이 속한 분야의 통상의 지식을 가진자는 본 발명의 정신을 벗어나지 않고 변형이 가능하고 이러한 변형은 본 발명의 범위에 속한다는 것을 이해할 것이다.The present invention has been described above only one embodiment, but as can be seen in the appended claims, those skilled in the art to which the present invention pertains may be modified without departing from the spirit of the present invention. It will be understood that it belongs to the scope of the invention.

상술한 본 발명에 따른 펄세이터방식 건조세탁기의 효과를 설명하면 다음과 같다.Referring to the effect of the pulsator type dry washing machine according to the present invention described above are as follows.

첫째, 본 발명에서는 펄세이터방식으로 세탁물을 세탁하므로 세탁효율이 좋으며, 동시에 세탁후의 세탁물을 내조에서 바로 건조시킬 수 있으므로 사용자의 편의가 향상된다는 이점이 있다.First, in the present invention, washing the laundry in a pulsator method is good washing efficiency, and at the same time there is an advantage that the convenience of the user can be improved since the laundry after washing can be immediately dried in the inner tank.

둘째, 본 발명에 따르면, 가열공기가 다수의 분사공에서 분사되며, 또한 상기 분사노즐이 회전하면서 가열공기를 내조에 분사하므로 세탁물을 보다 효과적으로 빠른 시간내에 건조시킬 수 있다는 이점이 있다.Second, according to the present invention, since the heating air is injected from a plurality of injection holes, and the injection nozzle is rotated to spray the heating air into the inner tank, there is an advantage that the laundry can be dried more effectively and quickly.
