본 발명은 드럼세탁기에 관한 것으로서, 특히 진동 감지와 수위 감지를 동시에 이룰 수 있도록 하는 진동 수위 감지장치 및 이를 구비하는 드럼세탁기에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a vibration level detecting device and a drum washing machine having the same, which can achieve both vibration detection and level detection.

도 1은 종래 기술에 따른 드럼세탁기가 도시된 구성도이다.1 is a block diagram showing a drum washing machine according to the prior art.

도 1을 참조하면, 종래 기술에 따른 드럼세탁기는 개구부가 형성되는 캐비닛(10)과, 개구부 내측에 설치되어 세탁수가 담수되는 터브(2)와, 터브(2) 내측에 회전 가능하게 설치되어 세탁물이 수납되는 드럼(4)과, 터브(2)에 설치되고 드럼(4)에 연결되는 구동장치(6)와, 터브(2)로부터 캐비닛(10) 외측으로 연장되어 세탁수를 공급하는 급수장치(8)와, 터브(2)로부터 캐비닛(10) 외측으로 연장되어 세탁수를 배출하는 배수장치(9)와, 터브(2)에 설치되어 터브(2) 내부로 담수되는 세탁수의 수위를 감지토록 하는 수위감지장치(20)를 포함한다.Referring to FIG. 1, the drum washing machine according to the related art is provided with a cabinet 10 having an opening formed therein, a tub 2 installed inside the opening to receive fresh water, and rotatably installed inside the tub 2. The drum 4 accommodated therein, the driving device 6 installed on the tub 2 and connected to the drum 4, and the water supply device extending from the tub 2 to the outside of the cabinet 10 to supply washing water. (8), a drainage device (9) extending from the tub (2) to the outside of the cabinet (10) to discharge the wash water, and the water level of the wash water installed in the tub (2) and fresh water into the tub (2). It includes a level sensor 20 for sensing.

여기서, 수위감지장치(20)는 터브(2)의 하측 단부로부터 상측 방향으로 연장되는 전달관(22)과, 전달관(22)이 상측 단부에 연결되는 압력센서(24)를 포함한다.Here, the water level detecting device 20 includes a delivery tube 22 extending upward from the lower end of the tub 2, and a pressure sensor 24 connected to the upper end of the delivery tube 22.

이로써, 터브(2) 내부에 세탁수가 공급되면 담수되는 세탁수의 일부분은 전달관(22)을 따라 캐비닛(50)의 상측으로 유동된다.As a result, when the wash water is supplied into the tub 2, a part of the wash water that is fresh water flows along the delivery pipe 22 to the upper side of the cabinet 50.

이때, 터브(2) 내부로 공급되는 세탁수의 양이 많을수록 전달관(22)을 따라 캐비닛(50) 상측으로 유동되는 세탁수가 많기 때문에 압력센서(24)에서 측정되는 압력에 따라 터브(2) 내부의 수위를 판단할 수 있게 된다.At this time, the greater the amount of wash water supplied into the tub (2), the greater the amount of wash water flowing along the delivery pipe (22) toward the cabinet (50), so the tub (2) according to the pressure measured by the pressure sensor (24). The internal water level can be determined.

도 2 내지 도 4를 참조하면, 본 발명의 일 실시예에 따른 드럼세탁기는 개구부가 형성되는 캐비닛(50)과, 개구부 내측에 설치되어 세탁수가 담수되는 터브(52)와, 터브(52) 내측에 회전 가능하게 설치되어 세탁물이 수납되는 드럼(54)과, 터브에 설치되고 드럼에 연결되는 구동장치(56)와, 터브(52)로부터 캐비닛(50) 외측으로 연장되어 세탁수를 공급하는 급수장치(58)와, 터브(52)로부터 캐비닛(50) 외측으로 연장되어 세탁수를 배출하는 배수장치(59)와, 터브에 설치되어 터브의 수위 및 진동의 정도를 측정하는 진동 수위 감지장치(80)를 포함한다.2 to 4, the drum washing machine according to an embodiment of the present invention, the cabinet 50 is formed with an opening, the tub 52 is installed inside the opening and fresh water wash, and the tub 52 inside A drum 54 rotatably installed in the laundry to accommodate the laundry, a driving device 56 installed on the tub and connected to the drum, and a water supply extending from the tub 52 to the outside of the cabinet 50 to supply the washing water; Apparatus 58, a drainage device 59 extending from the tub 52 to the outside of the cabinet 50 to discharge the wash water, and a vibration level sensor installed in the tub to measure the level of water and the degree of vibration of the tub ( 80).

여기서, 진동 수위 감지장치(80)는 터브(52)에 형성되는 공간부(82)와, 공간부(82)에 소정량 유동 가능하게 삽입되는 튜브(84)와, 튜브(84)에 연통되어 튜브(84)의 체적 변화량에 따라 작동유체가 유동되도록 하는 전달관(86)과, 전달관(86)에 설치되어 작동유체의 유동 여부에 따라 변화되는 압력을 측정하여 터브(52)의 수위 및 진동 여부를 판단하는 압력센서(88)와, 튜브(84)의 상단에는 설치되는 소정 무게의 중량물(87)울 포함한다.Here, the vibration level detecting device 80 is communicated with the space portion 82 formed in the tub 52, the tube 84 is inserted into the space portion 82 so as to be able to flow a predetermined amount, and the tube 84 The water level of the tub 52 by measuring the pressure that changes depending on whether the working fluid flows, and the delivery pipe 86 to allow the working fluid to flow in accordance with the volume change of the tube 84 and the working fluid flow and The pressure sensor 88 for determining whether the vibration and the upper end of the tube 84 includes a weight 87 of a predetermined weight to be installed.

이로써, 급수장치(58)에 의해 터브(52) 내측에 세탁수가 공급되면 터브(52)의 바닥면에 형성된 공간부(82) 내측에 삽입되는 튜브(84)의 상면을 세탁수가 가압하게 되고, 세탁수의 가압으로 인해 압축되는 튜브(84)는 내부에 충진된 작동유체가 전달관(86)을 따라 유동된다.Thus, when the wash water is supplied into the tub 52 by the water supply device 58, the wash water pressurizes the upper surface of the tube 84 inserted into the space 82 formed on the bottom surface of the tub 52. Due to the pressurization of the washing water, the tube 84 is compressed and a working fluid filled therein flows along the delivery pipe 86.

이렇게 유동되는 작동유체에 의해 압력센서(88)에서 측정되는 압력이 변화되는데, 이러한 압력 변화를 계산하여 터브(52)의 수위를 판단할 수 있게 된다.The pressure measured by the pressure sensor 88 is changed by the working fluid flowing in this way, and the level of the tub 52 can be determined by calculating the pressure change.

또한 세탁작동이 개시되어 터브(52)에 진동이 발생되면 튜브(84)가 공간부(82) 내부에서 유동되고, 이러한 튜브(84)의 유동에 의해 튜브(84)의 상면에 설치되는 중량물(87)이 유동된다.In addition, when the washing operation is started and the vibration is generated in the tub 52, the tube 84 flows in the space 82, the heavy material installed on the upper surface of the tube 84 by the flow of the tube 84 ( 87) flows.

이렇게 유동되는 중량물(87)은 튜브(84)를 가압하게 되므로 상기한 바와 같이 작동유체가 전달관(86)을 따라 유동되므로 압력센서(88)에서 발생되는 압력의 변화를 계산하여 터브(52)의 진동 정도를 판단할 수 있게 된다.Since the heavy material 87 flows by pressing the tube 84, the working fluid flows along the delivery pipe 86 as described above, so that the change in pressure generated by the pressure sensor 88 is calculated and the tub 52. It is possible to determine the degree of vibration.

상기와 같이 구성된 본 발명의 일 실시예에 따른 진동 수위 감지장치 및 이를 구비하는 드럼세탁기의 작용을 살펴보면 다음과 같다.Looking at the operation of the vibration level sensor and the drum washing machine having the same according to an embodiment of the present invention configured as described above are as follows.

먼저, 드럼(54) 내부에 세탁물을 수납한 후에 세탁작동을 개시하면 급수장치(58)에 의해 터브(52)에 세탁수가 공급된다.First, when laundry is started after storing laundry in the drum 54, the washing water is supplied to the tub 52 by the water supply device 58.

이때, 터브(52) 내부로 담수되는 세탁수는 중량물(87) 및 튜브(84)를 가압하여 튜브(84)가 압축되므로 튜브(84)에 충진되는 작동유체는 전달관(86)을 따라 상승하여 압력센서(88)에 의해 압력 변화를 측정할 수 있게 한다.At this time, the wash water freshwater into the tub 52 pressurizes the weight 87 and the tube 84 so that the tube 84 is compressed, so that the working fluid filled in the tube 84 rises along the delivery tube 86. To measure the pressure change by the pressure sensor 88.

이러한 압력변화를 계산하여 터브(52)에 담수되는 세탁수의 양을 판단하고, 세탁을 위한 적정 수위의 세탁수가 담수되었으면 급수장치(58)의 구동 정지한 후에, 구동장치(56)에 전원을 인가하여 드럼(54)이 회전되면서 세탁작동을 행하게 된다.The pressure change is calculated to determine the amount of wash water to be washed in the tub 52, and when the wash water at the proper level for washing is fresh, after the water supply unit 58 stops driving, the power source is supplied to the driving unit 56. By applying the drum 54 is rotated to perform the washing operation.

이렇게 세탁작동이 개시되면 드럼(54)의 회전에 의해 터브(52)에 진동이 발 생되는데, 터브(52)가 유동되면 중량물(87)이 유동되면서 튜브(84)를 가압하게 되고, 튜브(84)의 압축에 의해 작동유체가 전달관(86)을 따라 유동되므로 압력센서(88)에서 압력 변화를 측정할 수 있게 된다.When the washing operation is started, vibration is generated in the tub 52 by the rotation of the drum 54. When the tub 52 flows, the weight 84 flows and presses the tube 84, and the tube ( The working fluid flows along the delivery pipe 86 by the compression of 84 so that the pressure change can be measured by the pressure sensor 88.

이렇게 측정되는 압력 변화를 계산하여 터브(52)의 진동 정도를 판단할 수 있으므로 구동장치(56)의 제어나 별도의 완충장치의 구동 여부 및 제어를 행할 수 있게 된다.Since the vibration change of the tub 52 can be determined by calculating the pressure change measured in this way, the control of the driving device 56 or the driving of a separate shock absorber can be performed.
