Description

냉장고 가습장치의 가습팬 제어방법Humidification fan control method of refrigerator humidifier

본 발명은 냉장고 가습장치의 제어방법에 관한 것으로서, 특히 냉장고내의 습도에 따라 야채실의 일측에 설치되는 가습팬 구동용 BLDC모터의 속도를 제어하여 가습량을 가변할 수 있도록 한 냉장고 가습장치의 가습팬 제어방법에 관한 것이다.The present invention relates to a control method of a refrigerator humidifier, and in particular, to control the speed of a humidification fan driving BLDC motor installed at one side of a vegetable compartment according to the humidity in the refrigerator to control the humidification fan of the refrigerator humidifier. It is about a method.

일반적으로 냉장고내의 냉장실에는 야채나 과일등을 분리하여 보관할 수 있도록 별도의 야채실이 구비되어 있으며, 냉장실팬에 의해 냉장실과 동일한 온도의 냉기가 공급되어져 야채실 내부에서 순환됨으로써 냉장이 되고 있다.In general, the refrigerating chamber in the refrigerator is provided with a separate vegetable compartment to separate the vegetables or fruits, and the refrigeration chamber fan is supplied with cold air at the same temperature as the refrigerating compartment is circulated in the vegetable compartment is being refrigerated.

이와 같이 냉기만을 공급할 경우에는 통상적인 냉장만을 행하게 되므로 야채나 과일등을 장시간동안 보존할 경우 수분이 부족하여 말라 버리고, 신선도도 장시간 유지할 수 없는 문제점이 있었다.When only cold air is supplied in this way, since only normal refrigeration is performed, when the vegetables or fruits are stored for a long time, there is a problem that the moisture dries out and the freshness cannot be maintained for a long time.

그러나 최근에는 야채실의 일측에 가습장치를 구비하여 야채실내의 수분량이 항상 일정하게 유지되도록 하는 기술이 개발되었고, 이로 인해 야채나 과일등의 신선도가 향상됨은 물론 장기간 보존할 수도 있다.Recently, however, a technology has been developed to maintain a constant amount of moisture in a vegetable compartment by providing a humidifier on one side of the vegetable compartment. As a result, freshness of vegetables or fruits may be improved and may be preserved for a long time.

이러한 기능을 갖는 가습장치의 일 실시예가 대한민국 특허출원 제95-21651호(명칭 : 냉장고의 야채실 가습제어방법)에 개시되어 있다.An embodiment of a humidifier having such a function is disclosed in Korean Patent Application No. 95-21651 (Name: Method for controlling humidification of a vegetable compartment of a refrigerator).

도 1은 상기 실시예에 따른 종래의 냉장고에 설치된 가습장치의 단면도로서, 야채실(10)의 일측에 장착된 수조(20), 상기 수조(20)의 하부에 장착되어 저장된 물을 진동시켜 수증기로 만드는 진동자(30), 상기 수조(20)내에 저장된 물의 온도를 감지하는 온도감지센서(40), 증발기(미도시)에서 발생된 냉기를 야채실(10)로 공급하기 위한 가습팬(50)으로 구성된다.1 is a cross-sectional view of a humidifier installed in a conventional refrigerator according to the embodiment, the water tank 20 mounted on one side of the vegetable chamber 10, the water stored in the lower portion of the water tank 20 to vibrate to steam It consists of a vibrator 30, a temperature sensor 40 for detecting the temperature of the water stored in the water tank 20, the humidification fan 50 for supplying the cold air generated in the evaporator (not shown) to the vegetable chamber 10 do.

이와 같이 구성된 본 발명에 따른 냉장고 가습장치의 동작을 설명하면 다음과 같다.Referring to the operation of the refrigerator humidifier according to the present invention configured as described above are as follows.

먼저, 전원공급부(미도시)를 통하여 전원이 제어부(130)와 회로 각부에 인가되면 상기 제어부(130)는 구동부(140)(150)에 구동신호를 BLDC모터(120c)로 보내어 가습장치(120)의 진동부(120a)와 가습팬(120b)을 구동시킨다.First, when power is applied to the controller 130 and each circuit through a power supply unit (not shown), the controller 130 sends a driving signal to the BLDC motor 120c to the drivers 140 and 150 to humidify the device 120. Drive the vibration unit (120a) and the humidification fan (120b).

상기 진동부(120a)가 구동되면 수조(미도시)내에 저장된 물이 수증기로 바뀌어지게 되고 BLDC모터(120c)에 의해 구동되는 가습팬(120b)에 의한 유입된 냉기와의 온도차에 의해 야채실(미도시)에 습기가 공급되어 가습이 이루어지게 된다.When the vibrator 120a is driven, the water stored in the water tank (not shown) is changed into water vapor, and the vegetable chamber (not shown) due to the temperature difference with the cold air introduced by the humidification fan 120b driven by the BLDC motor 120c. Humidity is supplied to the humidification.

이때, 상기 습도감지부(100)는 가습장치(120)로부터 나오는 습도를 감지하여 제어부(130)로 감지된 신호를 보낸다.At this time, the humidity detection unit 100 detects the humidity coming from the humidifier 120 and sends a signal to the control unit 130.

상기 제어부(130)에 감지된 습도가 낮을 경우에 사용자가 가습돌입스위치부(110)의 가습돌입스위치(SW)를 누르면 상기 BLDC모터(120c)로 15V가 인가되어져 가습팬(120b)을 일정시간 빠르게 회전시켜 야채실로 많은 양의 습기를 송풍한다.When the humidity sensed by the controller 130 is low, when the user presses the humidification inrush switch SW of the humidification inrush switch unit 110, 15V is applied to the BLDC motor 120c to operate the humidification fan 120b for a predetermined time. It rotates quickly and blows a lot of moisture into the vegetable compartment.

상기 야채실이 일정습도에 도달했으면 상기 습도감지부(100)의 습도센서(T-S)의 온/오프 온도점에 의해 가습장치가 구동되는 이때 상기 BLDC모터(120c)로 12V를 인가시켜 가습팬(120b)을 일정시간 보통속도로 회전시킨다.When the vegetable chamber has reached a predetermined humidity, when the humidifier is driven by the on / off temperature point of the humidity sensor TS of the humidity sensing unit 100, 12V is applied to the BLDC motor 120c to humidify the fan 120b. ) Rotate at regular speed for a certain time.

한편, 통상시에는 사용자가 가습돌입스위치부(110)의 가습돌입스위치(SW)를 누르지 않더라도 상기 BLDC모터(120c)로 9V가 인가되어져 가습팬(120b)을 시간당 30초씩 회전시킨다.On the other hand, even if the user does not press the humidification inrush switch SW of the humidification inrush switch unit 110 in general, 9V is applied to the BLDC motor 120c to rotate the humidification fan 120b by 30 seconds per hour.

이와 같이 구성된 본 발명에 따른 냉장고 가습장치의 가습팬 제어방법을 도 4를 참조하여 설명하면 다음과 같다.The humidification fan control method of the refrigerator humidifier according to the present invention configured as described above will be described with reference to FIG. 4.

가습장치가 구동될 때 상기 제어부(130)는 사용자에 의해 가습돌입스위치부(110)의 가습돌입스위치(SW)가 선택조작되었는지 여부를 판단한다(S101).When the humidifier is driven, the control unit 130 determines whether the humidification inrush switch SW of the humidification inrush switch unit 110 is selected by the user (S101).

상기 가습돌입스위치가 선택되지 않았으면 상기 BLDC모터(120c)로 9V가 인가되어져 가습팬(120b)이 시간당 30초씩 회전된다(S102).If the humidification inrush switch is not selected, 9V is applied to the BLDC motor 120c so that the humidification fan 120b is rotated for 30 seconds per hour (S102).

상기 제어부(130)에 가습돌입스위치(SW)가 선택된 것으로 판단되면 상기 제어부(130)는 최대풍속으로 가습팬(120b)을 운전시켜야 되는지 운전조건을 판단하여(S103) 최대풍속으로 가습팬(120b)을 운전해야하는 조건이면 BLDC모터(120c)로 15V를 인가시켜 가습팬(120b)을 일정시간 빠르게 회전시킨다.When it is determined that the humidification inrush switch SW is selected in the controller 130, the controller 130 determines whether the humidification fan 120b should be operated at the maximum wind speed (S103) and the humidification fan 120b at the maximum wind speed. If the condition is to operate) 15V is applied to the BLDC motor 120c to rotate the humidification fan (120b) for a predetermined time.

상기 가습팬(120b)은 빠르게 회전되면서 많은 양의 습기를 야채실로 송풍한다(S104).The humidifying fan 120b is rapidly rotated and blows a large amount of moisture into the vegetable compartment (S104).

이때, 상기 제어부는 상기 야채실로 송풍된 습기가 일정습도까지 도달했는지 여부를 판단하여(S105) 일정습도까지 도달했으면 BLDC모터(120c)로 12V를 인가시켜 습도센서(T-S)의 온/오프 온도점에 의해 가습팬(120b)이 회전되도록 한다(S106).At this time, the control unit determines whether the humidity blown to the vegetable chamber reaches a predetermined humidity (S105) and when reaching the predetermined humidity to apply a 12V to the BLDC motor 120c to the on / off temperature point of the humidity sensor TS Humidification fan 120b is rotated by (S106).
