Description

냉장고의 문닫힘감지장치{Door closed sensing device in refrigerator}Door closed sensing device in refrigerator

본 발명은 냉장고의 문닫힘감지장치에 관한 것으로, 더욱 상세하게는 냉장고 문이 확실히 닫혔음을 소비자에게 알려주기 위한 냉장고의 문닫힘감지장치에 관한 것이다.The present invention relates to a door closing detection device for a refrigerator, and more particularly, to a door closing detection device for a refrigerator for informing a consumer that a refrigerator door is securely closed.

냉장고는 고내에서 필요로 하는 냉기를 공급하여, 보존되는 음식물의 신선도를 높이고, 음식물의 부패와 손상을 가능한 지연시키기 위한 주방기구이다. 이와 같은 냉장고는, 압축기와 열교환기로 이루어진 냉동사이클의 구동에 의해서 고내온도에 따라 필요한 냉기를 발생시켜서 공급한다. 따라서 고내온도가 높으면 많은냉기가 공급되고, 고내온도가 낮으면 냉기공급이 일시 중지되기도 한다.The refrigerator is a kitchen utensil for supplying cold air required in the refrigerator, increasing freshness of preserved foods, and delaying food corruption and damage as much as possible. Such a refrigerator generates and supplies necessary cold air according to the internal temperature of the refrigerator by driving a refrigeration cycle composed of a compressor and a heat exchanger. Therefore, a lot of cold air is supplied when the internal temperature is high, and cold air supply may be temporarily suspended when the internal temperature is low.

이렇게 동작되는 냉장고는, 사용자가 한번 문을 열때마다 고내 냉기가 외부로 유출되면서 고내에서 필요로 하는 냉기량이 다시 발생된다. 따라서 냉장고는 가능한 작은 횟수로 문 열림 횟수를 제한해야만, 고내에서 요구되는 냉기량이 작아지면서 전력소비량 또한 작게 된다.In the refrigerator operated in this way, the cold air in the refrigerator is leaked to the outside every time the user opens the door, and the amount of cold air required in the refrigerator is generated again. Therefore, the refrigerator should limit the number of door openings as small as possible, so that the amount of cold air required in the refrigerator is small and the power consumption is also small.

만일, 사용자가 냉장고의 문을 확실히 닫지 않은 경우에는, 고내 냉기가 계속해서 외부로 유출되고, 따라서 냉동사이클은 계속 구동하여 고내에서 요구하는 냉기량을 만족시켜야만 하는 것이다.If the user does not close the door of the refrigerator securely, cold air in the refrigerator continues to flow to the outside, and thus the refrigeration cycle must be continuously driven to satisfy the amount of cold air required in the refrigerator.

그러나 종래의 냉장고는 문의 닫힘여부를 사용자 눈에 의해서만 확인할 수 있었다. 따라서 냉장고 문을 열고 닫음에 있어서 주의를 하지 않으면, 냉장고 문이 열린상태를 장시간동안 유지하게 되어, 전력소비량이 많아짐과 더불어 보관 중인 음식물을 부패시키는 한 요인이 되었다. 특히, 노약자나 어린이는 냉장고 문을 열고 닫음에 주의를 하지 않는 경우가 대부분이며, 이러한 문제로 인해서 많은 가정에서 불필요한 전력낭비를 할 수 밖에 없었다. 더불어 보관중인 음식물이 외부온도에 노출됨에 따라서 부패되거나 손상될 우려가 있고, 이러한 문제로 인해서 소비자의 경제적 문제와 함께 음식물 쓰레기로 인한 여러가지 문제를 야기시키고 있다.However, the conventional refrigerator could only confirm whether the door is closed by the user's eyes. Therefore, if care is not taken in opening and closing the refrigerator door, the refrigerator door is kept open for a long time, which is a factor of increasing the power consumption and corrupting the food being stored. In particular, the elderly and children do not pay attention to the opening and closing of the refrigerator door in most cases, due to this problem was forced to waste unnecessary power in many families. In addition, there is a possibility that the food is stored in the corruption or damage as it is exposed to the outside temperature, and due to this problem is causing various problems due to food waste along with the economic problems of consumers.

따라서 본 발명의 목적은, 냉장고 문이 확실히 닫힘에 따른 확인음을 발생시켜서 소비자에게 알려주기 위한 냉장고 문닫힘감지장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a refrigerator door closing detection device for informing a consumer by generating a confirmation sound according to the refrigerator door being surely closed.

상기 목적을 달성하기 위한 본 발명에 따른 냉장고 문닫힘감지장치는, 냉장고 문이 열림과 닫힘을 감지하는 감지수단과; 상기 감지수단의 검출값에 기초해서 문이 열렸다가 닫혔을때, 문 닫힘여부를 판단하는 판단수단과; 상기 판단수단의 결과에 따라서 부저음을 발생하는 부저음발생수단을 포함하여 구성된다.Refrigerator door closing detection apparatus according to the present invention for achieving the above object, the detection means for detecting the opening and closing of the refrigerator door; Determining means for determining whether the door is closed when the door is opened and closed based on the detection value of the sensing means; And buzzer sound generating means for generating a buzzer sound according to the result of the determining means.

이하 첨부한 도면을 참조하여 본 발명에 따른 냉장고 문닫힘감지장치에 대해서 상세하게 설명한다.Hereinafter, a refrigerator door closing detection apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 냉장고 문닫힘감지장치의 구성도이다.1 is a block diagram of a refrigerator door closing detection apparatus according to the present invention.

본 발명에 따른 냉장고 문닫힘감지장치는 도시하고 있는 바와 같이, 냉장고 문의 닫힘을 감지하기 위한 문닫힘감지부(10)를 포함한다. 상기 문닫힘감지부(10)는, 일반적으로 냉장고의 문에 설치되는 도어 스위치를 이용할 수 있다. 즉, 상기 도어 스위치가 닫히면, 문이 닫힌 것으로 판단하고, 상기 도어 스위치가 계속해서 열려 있으면, 도어가 열려 있다고 판단한다.Refrigerator door closing detection apparatus according to the present invention, as shown, includes a door closing detection unit 10 for detecting the closing of the refrigerator door. The door closing detection unit 10 may use a door switch that is generally installed in the door of the refrigerator. That is, if the door switch is closed, it is determined that the door is closed, and if the door switch is kept open, it is determined that the door is open.

또한, 본 발명에 따른 냉장고 문닫힘감지장치는, 상기 문닫힘감지부(10)의 출력에 의해서 냉장고의 문이 열렸는지 또는 닫혔는지를 판단하는 마이크로컴퓨터(20)를 포함한다. 특히, 상기 마이크로컴퓨터(20)는, 상기 문닫힘감지부(10)의 검출신호에 기초해서 냉장고 문이 열렸다가 닫힌 순간에 문이 정확히 닫혔는지 여부를 판단한다.In addition, the refrigerator door closing detection apparatus according to the present invention includes a microcomputer 20 that determines whether the door of the refrigerator is opened or closed by the output of the door closing detection unit 10. In particular, the microcomputer 20 determines whether the door is correctly closed at the moment of opening and closing of the refrigerator door based on the detection signal of the door closing detecting unit 10.

즉, 본 발명에서 판단하고자하는 것은, 냉장고의 문이 사용자에 의해서 열렸다가 닫힐때, 정확히 닫혔는지 여부를 판단하기 위한 것이다. 따라서 상기 마이크로컴퓨터(20)는, 상기 문닫힘감지부(10)의 값이 열렸다가 닫혔을때, 검출되는 신호에 기초해서 냉장고의 문이 정확히 닫힘을 검출한다.That is, to determine in the present invention, when the door of the refrigerator is opened and closed by the user, it is to determine whether or not closed correctly. Therefore, the microcomputer 20 detects that the door of the refrigerator is closed correctly based on the signal detected when the value of the door closing detecting unit 10 is opened and closed.

그리고 본 발명은 상기 마이크로컴퓨터(20)에서 문이 정확히 닫혔다고 판단되었을때, 부저음을 발생하는 부저음출력부(30)를 더 포함한다. 상기 부저음출력부(30)는, 문이 정확히 닫혔음을 소비자에게 알려주기 위한 구성이다.The present invention further includes a buzzer sound output unit 30 for generating a buzzer sound when the microcomputer 20 determines that the door is correctly closed. The buzzer sound output unit 30 is a configuration for informing the consumer that the door is closed correctly.

다음은 상기 구성으로 이루어진 본 발명에 따른 냉장고의 문닫힘감지장치의 동작과정에 대해서 설명한다.Next will be described the operation of the door closing detection device of the refrigerator according to the present invention having the above configuration.

사용자가 냉장고 문을 열면, 상기 문닫힘감지부(10)는, 냉장고의 문이 열림을 감지하고, 그에 따른 동작 절환을 수행한다. 이때 문닫힘감지부(10)의 수행동작에 따라서 마이크로컴퓨터(20)는 냉장고 문이 열렸음을 판단한다.When the user opens the refrigerator door, the door closing detection unit 10 detects the opening of the door of the refrigerator, and performs the operation switching accordingly. At this time, the microcomputer 20 determines that the refrigerator door is opened according to the performance of the door closing detecting unit 10.

그리고 사용자가 냉장고 고내에 음식물을 넣거나 또는 뺀 후, 냉장고 문을 닫으면, 문의 닫힌 상태에 따라서 상기 문닫힘감지부(10)의 검출값이 다르게 결정된다. 일 예로, 사용자가 문을 정확히 닫지 않은 경우에는 상기 문닫힘감지부(10)는 이전 동작상태를 그대로 유지한다. 그러나 사용자가 문을 정확히 닫으면, 상기 문닫힘감지부(10)는 동작상태를 반대의 상태로 절환한다.When the user closes the refrigerator door after putting or removing food into the refrigerator, the detection value of the door closing detecting unit 10 is determined differently according to the closed state of the door. For example, when the user does not close the door correctly, the door closing detection unit 10 maintains the previous operating state. However, if the user closes the door correctly, the door closing detection unit 10 switches the operation state to the opposite state.

이와 같이 상기 문닫힘감지부(10)는 냉장고 문이 열렸다가 닫혔을때, 또는 닫혔다가 열렸을때 동작상태를 절환하게 된다. 그리고 마이크로컴퓨터(20)는 상기 문닫힘감지부(10)의 동작상태에 따라서 냉장고의 문이 열렸음을 또는 닫혔음을 판단하게 되는 것이다.As such, the door closing detection unit 10 switches the operation state when the refrigerator door is opened and closed, or when the door is closed and opened. The microcomputer 20 determines whether the door of the refrigerator is opened or closed according to the operation state of the door closing detecting unit 10.

이렇게 판단되는 상태에서, 상기 마이크로컴퓨터(20)는, 상기 문닫힘감지부(10)의 동작상태가, 닫힘상태에서 열림상태로 전환되었다가 다시 닫힘상태로 전환되었다고 판단될때, 사용자가 냉장고 문을 열었다가 정확히 닫았다고 판단한다. 따라서 이때 부저음 출력부(30)를 제어하여, 냉장고 문이 정확히 닫혔음에 따른 확인음이 발생되도록 한다.In this state, when the microcomputer 20 determines that the operation state of the door closing detection unit 10 is changed from the closed state to the open state and then to the closed state, the user opens the refrigerator door. I think it opened and closed correctly. Therefore, at this time, the buzzer sound output unit 30 is controlled so that a confirmation sound is generated when the refrigerator door is closed correctly.

그러나 상기 문닫힘감지부(10)의 동작상태가 닫힘상태에서 열림상태로 전환된 후, 계속해서 그 상태를 유지하면, 사용자가 냉장고 문을 열었다가 정확히 닫히지 않았다고 판단한다. 따라서 이 경우에는 부저음을 발생시키지 않는다.However, if the operation state of the door closing detection unit 10 is changed from the closed state to the open state and then continues to maintain the state, it is determined that the user opens the refrigerator door and does not close it correctly. Therefore, in this case, no buzzer sounds.

이와 같이, 문이 닫힘에 따른 부저음이 발생되지 않았을때, 사용자는 냉장고 문이 정확히 닫히지 않았음을 판단하고, 다시 정확히 닫은 동작을 수행하게 된다.As such, when the buzzer sound is not generated due to the closing of the door, the user determines that the refrigerator door is not closed correctly, and performs the correct closing operation again.

즉, 본 발명은 사용자가 냉장고 문을 열고 사용한 후, 확실히 닫혔을때 확인음을 발생시켜서, 소비자로 하여금 냉장고 문이 확실히 닫혔다는 것을 알려주기 위한 것을 기본적인 기술적 사상으로 하고 있다.That is, the present invention has a basic technical idea to generate a confirmation sound when the user opens and uses the refrigerator door and closes it to make sure that the refrigerator door is closed securely.

그리고 이와 같은 본 발명의 기술적 사상의 범위 내에서, 당업계의 통상의 지식을 가진 자에게 있어서는 다양한 변형이 가능함은 물론이다.And within the scope of the technical idea of the present invention, of course, various modifications are possible to those skilled in the art.

이상과 같이 설명된 본 발명은 다음의 효과를 갖게 된다.The present invention described above has the following effects.

첫째, 소비자가 냉장고를 사용하여 문을 닫았을때, 부저음을 통해서 문이 확실히 닫힘에 따른 확인을 시켜줄 수가 있다.First, when a consumer closes the door using the refrigerator, the buzzer can confirm that the door is closed.

둘째, 소비자가 냉장고를 사용하여 문이 올바로 닫지 않은 경우, 냉기 누설로 인한 고내 온도 상승으로 보관중인 음식물의 부패와 손상을 입힐 수 있는데, 부저음을 통해 문이 확실히 닫혔음을 소비자에게 알려줄 수 있으므로서 이러한 점을 방지할 수가 있다.Second, if the door is not closed properly using the refrigerator, the temperature inside the high temperature caused by the leakage of cold air can cause the food to decay and damage. This can be prevented.

셋째, 고내 온도 상승으로 냉기 발생을 계속 유도함에 따라서 소비전력의 상승으로 인한 경제적 손실을 야기시킬 수 있는데, 부저음을 통해 문이 확실히 닫혔음을 소비자에게 알려줄 수 있으므로서 이러한 점을 방지할 수가 있다.Third, as the internal temperature continues to induce the occurrence of cold air, it can cause economic losses due to the increase in power consumption. This can be prevented by informing the consumer that the door is closed by the buzzer sound.

넷째, 이러한 점들과 더불어 제품에 대한 신뢰도를 높이는 것을 기대할 수 있다.Fourth, in addition to these points, it can be expected to increase the reliability of the product.
