Description

세탁기의 콘트롤패널 냉각장치Control panel chiller of washing machine

본 고안은 세탁기의 콘트롤패널 냉각장치에 관한 것으로서, 더욱 상세하게는 세탁이 진행되는 동안 콘트롤패널 쪽으로 세탁수의 일부를 순환시켜 콘트롤패널에서 발생되는 열이 수냉되도록 함으로서, 콘트롤패널의 오동작이 방지되도록한 세탁기의 콘트롤패널 냉각장치에 관한 것이다.The present invention relates to a control panel cooling device of a washing machine, and more particularly, by circulating a part of the washing water toward the control panel during washing to allow the heat generated from the control panel to be cooled, thereby preventing malfunction of the control panel. A control panel cooling device of a washing machine.

일반적으로 세탁기는 도 1에 도시된 바와 같이 직사각형의 본체(10) 내부에 원통형의 수조(11)가 걸이봉(10a)에 의해 매달려 설치되고 수조(11) 내부에 세탁조(12)와 펄세이터(13)가 설치된다. 펄세이터(13)는 세탁시 정역회전 되면서 회전수류를 일으키는 것으로서, 회전수류에 의해 빨래감이 서로 비벼지며 세탁된다. 또한 세탁조(12)는 탈수시 고속으로 회전되며 고속회전되는 과정에서 빨래감에 원심력이 작용되어 탈수된다. 또한 수조(11)의 저면에 모터(14)로 구동되는 동력절환부재(15)가 설치되고 동력절환부재(15)에 의해 펄세이터(13) 및 세탁조(12)가 선택적으로 회전된다. 또한 본체(10) 상부의 상판(16)에 세탁,행굼과 탈수 등의 기능을 콘트롤하는 콘트롤패널(17)이 설치된다.In general, a washing machine has a cylindrical water tank 11 installed inside a rectangular main body 10 by a hook rod 10a as shown in FIG. 1, and a washing tank 12 and a pulsator inside the water tank 11. 13) is installed. The pulsator 13 is rotated forward and reverse during washing to cause a rotational flow, the washing is rubbed with each other by the rotational flow. In addition, the washing tank 12 is rotated at a high speed during dehydration and the centrifugal force is applied to the laundry during the high speed rotation to be dehydrated. In addition, a power switching member 15 driven by a motor 14 is installed at the bottom of the water tank 11, and the pulsator 13 and the washing tank 12 are selectively rotated by the power switching member 15. In addition, a control panel 17 for controlling functions such as washing, rinsing and dehydration is installed on the upper plate 16 on the upper portion of the main body 10.

이처럼 구성된 종래의 세탁기는 세탁조(12) 내부에 빨래감과 세탁수가 담긴 다음 모터(14)의 구동으로 동력절환부재(15)가 정역회전 되면 이의 회전력이 펄세이터(13)에 전달되어 회전수류가 발생된다. 이때 발생되는 회전수류에 의해 빨래감이 서로 비벼지며 세탁이 진행되고 또한 세탁과정에서 행굼이 동시에 수행된다. 세탁이 완료되면 세탁수가 배수된 뒤 탈수가 진행된다. 즉 모터(14)의 구동으로 동력절환부재(15)가 일방향으로 고속회전 되면 세탁조(12)가 함께 고속회전 되면서 내부의 빨래감이 원심력에 의해 탈수된다.The conventional washing machine configured as described above includes laundry and washing water in the washing tank 12, and then, when the power switching member 15 is rotated forward and backward by driving the motor 14, its rotational force is transmitted to the pulsator 13 to generate rotational water flow. do. At this time, the washing flow is rubbed with each other by the rotating water flow generated, washing proceeds, and the rinsing is simultaneously performed in the washing process. When the washing is completed, the washing water is drained and then dewatered. That is, when the power switching member 15 is rotated at a high speed in one direction by the driving of the motor 14, the washing tub 12 is rotated at a high speed while the internal laundry is dehydrated by centrifugal force.

그러나 종래의 세탁기는 세탁 또는 탈수과정에서 이를 콘트롤하는 콘트롤패널(17)에 열이 발생되며 세탁을 장시간할 경우 고열로 인하여 오동작을 일으킬 우려가 있다. 즉 콘트롤패널(17)을 구성하는 회로부품(트렌지스터, 직접회로 및 마이크로컴퓨터)중에 열을 발생하는 부품 들이 있으며 이들 부품들은 별도의 방열핀이 구비되어 열기를 공기중에 자연 방열시킨다. 그러나 세탁이 장시간 이루어질 경우 방열핀의 방열능력이 초과되어 그 열기가 콘트롤패널에 직접 작용되며 이때 다른 부품들에 영향을 주어 오동작을 일으키게 되고 부품의 수명을 단축하는 등의 단점이 있다.However, in the conventional washing machine, heat is generated in the control panel 17 that controls the washing or dehydration process, and there is a risk of malfunction due to high heat when washing for a long time. That is, there are components that generate heat in the circuit components (transistor, integrated circuit and microcomputer) constituting the control panel 17, these components are provided with a separate heat radiation fins to naturally dissipate heat in the air. However, if the washing is performed for a long time, the heat dissipation ability of the heat radiation fin is exceeded, and the heat is directly acted on the control panel.

본 고안은 종래의 문제점을 감안하여 개발한 것으로서, 본 고안의 목적은 세탁이 진행되는 동안 회전수류의 원심력에 의해 세탁수의 일부가 콘트롤패널 쪽으로 강제 순환되도록하여 콘트롤패널에서 발생되는 열기가 강제 수냉되도록 함으로서, 특히 장시간 세탁을 할 때 콘트롤패널의 방열능력이 향상되도록한 세탁기의 콘트롤패널 냉각장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to force a part of the wash water to be circulated to the control panel by the centrifugal force of the rotating water during the washing process, so that the heat generated from the control panel is forced to cool water. In particular, to provide a control panel cooling device of a washing machine to improve the heat dissipation ability of the control panel, especially when washing for a long time.

It is provided in a zigzag form and has an inlet through which a washing water is forced to circulate toward the cooling water pipe by a centrifugal force of rotational water generated when the pulsator rotates on one side of the water tank.

이하 본 고안의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안 냉각장치의 개략적인 사시도 이고 도 3은 본 고안 냉각장치의 측단면도 로서, 도 1과 동일 구성요소는 동일 부호를 사용하여 본 고안을 설명한다. 본체(10)의 상부를 덮는 상판(16)의 전방으로 콘트롤패널(17)이 놓이는 콘트롤실(18)이 구비되고 콘트롤실(18)의 바닥에 냉각수관(20)이 지그재그 형태로 구비된다. 또한 수조(11) 하부의 일측으로 입구(21)가 형성되고 입구(21)가 호스(23)를 통하여 냉각수관(20)과 연결된다. 이때 입구(21)는 수조(11)의 내주면 쪽으로 돌출된 유도판(25)이 구비되며 회전수류가 유도판(25)에 충돌되어 입구(21) 쪽으로 안내된다. 또한 입구(21)로 유입되는 세탁수는 원심력에 의해 호스(23)를 타고 상부로 펌핑되어 냉각수관(20) 쪽으로 강제 순환된다. 또한 수조(11) 상부의 외주면에 출구(22)가 형성되고 냉각수관(20)이 호스(24)를 거쳐 출구(22)와 연통된다. 따라서 냉각수관(20)으로 순환되는 세탁수가 출구(22)를 따라 수조(11) 내부로 회수된다.Figure 2 is a schematic perspective view of the present invention cooling device and Figure 3 is a side cross-sectional view of the present invention cooling device, the same components as in Figure 1 will be described the present invention using the same reference numerals. The control chamber 18 in which the control panel 17 is placed in front of the upper plate 16 covering the upper portion of the main body 10 is provided, and the coolant pipe 20 is provided in a zigzag form at the bottom of the control chamber 18. In addition, an inlet 21 is formed at one side of the lower portion of the water tank 11, and the inlet 21 is connected to the coolant pipe 20 through the hose 23. At this time, the inlet 21 is provided with a guide plate 25 protruding toward the inner circumferential surface of the water tank 11 and the rotational flow impinges on the guide plate 25 is guided toward the inlet 21. In addition, the washing water flowing into the inlet 21 is pumped upward by the hose 23 by centrifugal force and forcedly circulated toward the cooling water pipe 20. In addition, an outlet 22 is formed on the outer circumferential surface of the upper portion of the water tank 11, and the cooling water pipe 20 communicates with the outlet 22 via the hose 24. Therefore, the wash water circulated to the cooling water pipe 20 is recovered along the outlet 22 into the water tank 11.

이처럼 구성된 본 고안은 콘트롤패널(17)이 놓이는 콘트롤실(18)의 바닥에 세탁수가 순환되는 냉각수관(20)이 지그재그 형태로 배열된다. 또한 수조(11)의 저면에 형성된 입구(21)가 냉각수관(20)의 선단과 호스(23)로 연결되고 수조(11)의 상부에 형성된 출구(22)가 냉각수관(20)의 후단과 호스(24)로 각각 연결되어 세탁수가 순환된다. 이같은 본 고안은 세탁조(12) 내부에 빨래감과 세탁수가 담긴 상태에서 세탁이 진행되면 펄세이터(13)의 정역회전에 따라 회전수류가 발생되면서 빨래감이 서로 비벼지며 세탁이 진행된다. 또한 세탁과정에서 회전수류의 일부가 유도판(25)에 충돌되어 입구(21) 쪽으로 유입된다.In the present invention configured as described above, the coolant pipe 20 through which the washing water is circulated is arranged in a zigzag form on the bottom of the control room 18 on which the control panel 17 is placed. In addition, the inlet 21 formed at the bottom of the water tank 11 is connected to the front end of the cooling water pipe 20 and the hose 23, and the outlet 22 formed at the top of the water tank 11 is connected to the rear end of the cooling water pipe 20. The washing water is circulated by connecting to the hose 24, respectively. The present invention is such that when the washing is carried out in the washing tank 12 in the state containing the washing water and the washing water is rubbed with each other while rotating water flow in accordance with the forward and reverse rotation of the pulsator 13 is in progress. In addition, in the washing process, a part of the rotational water collides with the guide plate 25 and flows toward the inlet 21.

이때 유입되는 세탁수는 원심력에 의해 호스(23)를 타고 상부로 강제 상승되고 냉각수관(20)으로 순환된다. 따라서 냉각수관(20)의 직 상부에 놓이는 콘트롤패널(17)이 수냉된다. 즉 콘트롤패널(17)은 세탁기가 작동되는 동안 각종 회로부품에서 열이 발생된다. 이때 세탁을 장시간 하면 이들 부품들의 방열성이 저하되며 그 열기가 콘트롤패널(17)의 다른 부품들에 영향을 주어 기기의 오동작을 일으킬 우려가 있다. 이때 콘트롤패널(17)의 저면으로 설치된 냉각수관(20)의 내부로 세탁수가 순환됨으로 콘트롤패널(17)에서 발생되는 열기가 수냉되어 방열성이 저하되지 않는다.At this time, the washing water introduced is forced up to the upper portion by the hose 23 by the centrifugal force and circulated to the cooling water pipe 20. Therefore, the control panel 17 placed directly above the cooling water pipe 20 is water cooled. That is, the control panel 17 generates heat from various circuit components while the washing machine is operating. In this case, if the washing is performed for a long time, the heat dissipation of these parts is lowered, and the heat may affect other parts of the control panel 17, causing a malfunction of the device. At this time, since the wash water is circulated inside the coolant pipe 20 installed at the bottom of the control panel 17, heat generated from the control panel 17 is cooled with water, and heat dissipation is not deteriorated.

이상에서와 같이 본 고안에 따르면 콘트롤패널이 설치된 콘트롤실의 내부로 냉각수관이 설치되고 수조 하부에 세탁수가 유입되는 입구가 형성된다. 또한 입구와 냉각수관이 호스로 연결됨에 따라 세탁과정에서 펄세이터의 회전으로 발생되는 회전수류의 원심력에 의해 세탁수의 일부가 호스를 타고 냉각수관 쪽으로 순환된다. 따라서 콘트롤패널에 설치된 각종 회로부품으로부터 발생되는 열기가 강제 수냉됨으로 장시간 세탁을 할 때 기기의 오동작이 발생되지 않는 등의 효과가 있다.As described above, according to the present invention, a cooling water pipe is installed inside the control room in which the control panel is installed, and an inlet through which the washing water flows into the lower part of the water tank is formed. In addition, as the inlet and the cooling water pipe are connected to the hose, part of the washing water is circulated toward the cooling water pipe by the centrifugal force of the rotating water generated by the rotation of the pulsator during the washing process. Therefore, the heat generated from the various circuit components installed in the control panel is forcibly water-cooled, so that there is an effect that the malfunction of the device does not occur when washing for a long time.
