Embodiments that include a substitutable component as an equivalent in the elements can be included in the scope of the present invention.
본 발명의 일 실시예에 따른 제빙기(10)는 도 2 내지 도 9에 도시된 바와 같이 물이 저장되는 트레이(T)와, 상기 트레이(T) 일 측에 구비되고 제어부가 내장되는 하우징(400)을 포함한다. 이때, 상기 트레이(T) 중 하우징(400) 방향 측면에 일 부분이 개방되어 형성되는 장착홈(T1)을 포함하고, 상기 장착홈(T1)에 장착되고 상기 트레이(T)에 담겨지는 물과 접촉하며 상기 하우징(400) 일 측에 설치되는 정전 용량 방식의 수위 측정 장치(100)를 포함한다.The ice maker 10 according to an embodiment of the present invention includes a tray T in which water is stored, and a housing 400 provided on one side of the tray T and having a control unit as shown in FIGS. 2 to 9. ). At this time, including a mounting groove (T1) that is formed by opening a portion on the side surface of the housing (400) of the tray (T), mounted in the mounting groove (T1) and the water contained in the tray (T) It includes a capacitive water level measuring device 100 in contact and installed on one side of the housing 400.
즉, 본 발명에 의하면 트레이(T)로 공급된 물의 수위를 측정한다. 이러한 물의 수위를 측정하면 트레이(T)에 공급된 물의 양을 산출할 수 있다. 따라서, 본 발명은 물의 공급 시간에 따라 트레이(T)에 공급된 물의 양을 조절하는 것이 아니라 트레이(T)에 공급된 물의 수위를 직접 측정하므로 물의 수압이 변동되어도 공급된 물의 양을 정확하게 측정할 수 있다.That is, according to the present invention, the water level of the water supplied to the tray T is measured. By measuring the water level, it is possible to calculate the amount of water supplied to the tray T. Therefore, the present invention does not adjust the amount of water supplied to the tray T according to the supply time of water, but directly measures the water level of the water supplied to the tray T, so even if the water pressure of the water changes, it is possible to accurately measure the amount of water supplied. Can.
본 발명의 수위 측정 장치(100)는 정전 용량 방식을 이용한다. 상기 정전 용량 방식의 수위 측정 장치는 전극부와 상기 전극부를 감싸는 케이스로 구성된다. 이러한 수위 측정 장치는 접하는 수위에 따라 정전 용량이 변화하며 이러한 정전 용량 변화를 측정하여 수위를 측정한다. 상술된 정전 용량 방식의 수위 측정 장치 자체는 널리 알려진 것으로서 한국등록특허 제10-1071071호, 한국 공개 특허 제10-2018-0031865호 등에 자세히 기재되어 있어 이에 대한 설명과 도시는 생략한다.The water level measuring device 100 of the present invention uses an electrostatic capacity method. The capacitive water level measuring device is composed of an electrode portion and a case surrounding the electrode portion. In such a water level measuring device, the electrostatic capacity changes according to the water level encountered, and the water level is measured by measuring the change in the electrostatic capacity. The above-described electrostatic capacitive water level measuring device itself is widely known and is described in detail in Korean Patent Registration No. 10-1071071, Korean Patent Publication No. 10-2018-0031865, and the description and illustration thereof are omitted.
이러한 정전 용량 방식의 수위 측정 장치(100)는 상기 트레이(T) 중 하우징(400) 방향 측면에 일 부분이 개방되어 형성되는 장착홈(T1)에 삽입된다. 상기 수위 측정 장치(100)를 안정적으로 고정하기 위해 상기 하우징(400) 일 측에서 돌출되어 형성되고 상기 정전 용량 방식의 수위 측정 장치(100)의 상면을 가압하는 가압판(430)을 포함한다. 즉, 상기 수위 측정 장치(100)가 상기 장착홈(T1)에 삽입된 상태에서 상기 가압판(430)이 수위 측정 장치(100)를 하방향으로 가압하게 되어 상기 수위 측정 장치(100)가 장착홈(T1)에 안정적으로 고정된다.The capacitive water level measuring device 100 is inserted into a mounting groove T1 in which a portion of the tray T is opened and formed on a side surface of the housing 400. In order to stably fix the water level measuring device 100, it is formed to protrude from one side of the housing 400 and includes a pressure plate 430 that presses the upper surface of the capacitive water level measuring device 100. That is, while the water level measuring device 100 is inserted into the mounting groove T1, the pressure plate 430 presses the water level measuring device 100 downward, so that the water level measuring device 100 is mounted. It is stably fixed to (T1).
한편, 상기 트레이(T) 중 하우징(100) 방향 측면에 구비되는 한 쌍의 온도 퓨즈(200)와, 상기 한 쌍의 온도 퓨즈(200) 사이에 구비되는 온도 센서(300)를 더 포함한다. 즉, 상기 온도 센서(300)에 의해 트레이(T)의 온도를 확인한다.Meanwhile, a pair of temperature fuses 200 provided on a side surface of the housing 100 in the tray T and a temperature sensor 300 provided between the pair of temperature fuses 200 are further included. That is, the temperature of the tray T is checked by the temperature sensor 300.
트레이(T)에는 히터(HE)가 구비되어 얼음 취출 시 트레이(T)를 가열하게 된다. 이때, 상기 트레이(T)의 온도가 설정된 범위를 벗어나면 않되므로 상기 온도 센서(300)가 구비된다.The heater T is provided in the tray T to heat the tray T when taking out ice. At this time, since the temperature of the tray T should not exceed the set range, the temperature sensor 300 is provided.
또한, 특정 이유로 상기 트레이(T)의 온도가 설정된 범위를 벗어하는 경우 상기 히터(HE)로 공급되는 전원을 차단하기 위해 온도 퓨즈(200)가 구비된다. 상기 온도 퓨즈(200)는 트레이(T)의 온도가 설정된 범위 이상으로 상승하면 퓨즈가 끊어져서 전원 공급이 차단된다. 즉, 상기 온도 센서(300)가 고장이 난 경우에도 상기 온도 퓨즈(200)에 의해 과도한 전원 공급이 차단되어 안정적인 제빙기 구동이 가능해진다.In addition, a temperature fuse 200 is provided to cut off power supplied to the heater HE when the temperature of the tray T is out of a predetermined range for a specific reason. In the temperature fuse 200, when the temperature of the tray T rises above a set range, the fuse is blown to cut off power supply. That is, even when the temperature sensor 300 is broken, excessive power supply is cut off by the temperature fuse 200 to enable stable ice machine driving.
상기 온도 퓨즈(200)와 온도 센서(300)를 장착하기 위해 상기 하우징(400)에는 상기 한 쌍의 온도 퓨즈(200)가 장착되는 온도 퓨즈 장착부(410)와, 상기 온도 센서(300)가 장착되는 온도 센서 장착부(420)를 포함한다.In order to mount the temperature fuse 200 and the temperature sensor 300, the housing 400 is equipped with a temperature fuse mounting unit 410 in which the pair of temperature fuses 200 are mounted and the temperature sensor 300.

상기 푸싱부(411)는 상기 온도 퓨즈(200)를 트레이(T)측으로 가압한다. 상기 푸싱부(411)에 의해 상기 온도 퓨즈(200)가 트레이(T)에 밀착되어 상기 트레이(T)에 발생된 열이 온도 퓨즈(200)로 전달되어 상술된 바와 같이 상기 트레이(T)의 온도가 설정된 범위 이상으로 상승하는 경우 온도 퓨즈(200)가 끊어지게 된다.The pushing unit 411 presses the temperature fuse 200 toward the tray T side. As the temperature fuse 200 is brought into close contact with the tray T by the pushing unit 411, heat generated in the tray T is transferred to the temperature fuse 200, so that the tray T of the tray T is as described above. When the temperature rises above a set range, the temperature fuse 200 is blown.
이러한 푸싱부(411)는 상기 제1개방부(481)사이를 연결하는 베이스(411-1)와, 상기 베이스(411-1)상에서 상향 연장되어 온도 퓨즈(200)를 트레이(T)측으로 가압하는 가압 바아(411-3)와 상기 베이스(411-1) 또는 가압 바아(411-3)에서 트레이(T)측으로 돌출하어 온도 퓨즈(200)의 하측을 지지하는 판체 형상의 받침부(411-2)를 포함한다.

이때, 상기 가압 바아(411-3)의 폭은 상기 제1개방부(481)의 폭보다 작게 형성되어 상기 가압 바아(411-3)의 양 측은 개방된다.At this time, the width of the pressure bar (411-3) is formed smaller than the width of the first opening portion 481, both sides of the pressure bar (411-3) is opened.
즉, 온도 퓨즈(200)의 양 측은 상기 걸림구(412)에 의해 걸림되어 고정되고 하측은 상기 받침부(411-1)에 의해 지지되며 상기 온도 퓨즈(200)의 배면은 상기 가압 바아(411-3)에 의해 가압되어 트레이(T)측으로 향하게 된다. 이러한 구성에 의해 상술된 바와 같이 상기 온도 퓨즈(200)는 트레이(T)에 밀착된다. 한편, 상기 가압 바아(411-3)의 양 측은 개방되어 있으므로 변형 가능하게 구비될 수 있고 이에 의해 상기 온도 퓨즈(200)를 가압할 수 있다.That is, both sides of the temperature fuse 200 are locked and fixed by the locking hole 412, the lower side is supported by the support portion 411-1, and the rear surface of the temperature fuse 200 is the pressure bar 411 Pressed by -3), it is directed to the tray T side. As described above by this configuration, the temperature fuse 200 is in close contact with the tray T. On the other hand, since both sides of the pressure bar 411-3 are open, it can be provided to be deformable, whereby the temperature fuse 200 can be pressed.
상기 온도 퓨즈(200)는 한 쌍(210,220)으로 구비되므로 상기 온도 퓨즈(200)가 장착되는 온도 퓨즈 장착부(410) 역시 한 쌍으로 구비된다. 상기 한 쌍의 온도 퓨즈(200) 사이에 온도 센서 장착부(420)가 구비되고, 이러한 온도 센서 장착부(420)에 온도 센서(300)가 장착된다.Since the temperature fuse 200 is provided as a pair 210 and 220, the temperature fuse mounting portion 410 on which the temperature fuse 200 is mounted is also provided as a pair. A temperature sensor mounting unit 420 is provided between the pair of temperature fuses 200, and the temperature sensor 300 is mounted on the temperature sensor mounting unit 420.
상기 온도 센서 장착부(420)는 상기 하우징 본체(480)의 제2개방부(482)에 형성된다. 이때, 상기 온도 센서 장착부(420)는 상기 제2개방부(482)의 양 내측면에 형성되는 걸림구(421)를 포함한다. 이러한 걸림구(421)는 쐐기 형상을 가질 수 있으며 이러한 걸림구(421)가 상기 온도 센서(300)를 파지하여 고정할 수 있다.The temperature sensor mounting portion 420 is formed in the second opening portion 482 of the housing body 480.
