The parts are the same, so description is omitted.
발광부(512)와 수광부(522)는 손잡이홈(321) 내부로 인입하는 손을 잘 감지할 수 있는 위치에 설치되어야 한다. 더욱 바람직하게는 손잡이홈(322) 입구부분에 설치된다.The light emitting unit 512 and the light receiving unit 522 should be installed at a position capable of sensing a hand drawn into the handle groove 321. More preferably, the handle groove 322 is installed at the inlet portion.
사용자가 도어(11)를 개방하고자 손잡이홈(322) 내부로 손을 인입시키면, 상기 손은 상기 광학식 센서(502)가 설치된 손잡이홈(322) 입구를 반드시 지나가게 된다. 따라서, 발광부(512)와 수광부(522) 사이를 손이 가리게 되므로, 이를 감지한 광학식 센서(502)는 제어부(미도시)로 신호를 보내게 되고, 그 뒤의 과정은 상기 터치스위치(501)로 구성한 예와 동일하다.When the user inserts his hand into the handle groove 322 to open the door 11, the hand must pass through the entrance of the handle groove 322 in which the optical sensor 502 is installed. Therefore, since the hand covers the light emitting unit 512 and the light receiving unit 522, the optical sensor 502 that detects the signal sends a signal to a control unit (not shown), and the subsequent process is performed by the touch switch 501. Same as the example configured with).
또한, 전술한 실시예에서는 핸들의 표면에 전도성재질의 접촉부가 별도로 설치되었으나, 핸들의 재질이 전도성재질로 이루어지면, 상기와 같은 별도의 전도성재질의 접촉부를 설치할 필요 없이, 상기 전도성재질로 이루어진 핸들의 일측에 터치스위치를 결합하여 구성할 수도 있다.In addition, in the above-described embodiment, the contact portion of the conductive material is separately installed on the surface of the handle, but if the material of the handle is made of a conductive material, the handle made of the conductive material without the need to install a separate contact portion as described above It can also be configured by combining a touch switch on one side of the.
이상에서 살펴본 바와 같이, 본 발명에 의하면, 식기세척기가 고온헹굼과정일 때, 사용자가 도어를 개방하려 하면, 식기세척기의 안전장치가 도어를 개방하기 전에 이를 감지하고 사용자에게 경보를 하여 사용자의 주의를 환기시켜주므로, 사용자가 입을 수 있는 화상등의 사고를 미연에 방지할 수 있어 제품의 안전성을 배가시킬 수 있고, 또한, 제품의 신뢰성을 높일 수 있는 효과가 있다.As described above, according to the present invention, when the user attempts to open the door when the dishwasher is in the high temperature rinsing process, the safety device of the dishwasher detects this before opening the door and alerts the user to the user's attention. By ventilating, it is possible to prevent accidents such as burns that a user may suffer in advance, thereby increasing the safety of the product and increasing the reliability of the product.
