Description

공기청정기의 필터 교환주기 측정방법 {Measuring method of filter change cycle of air purifier}Measuring method of filter change cycle of air purifier

본 발명은 공기청정기의 필터 교환주기 측정방법에 관한 것으로, 특히 공기청정기(또는 전열교환기, 환기장치 등)의 미세먼지, 총부유세균, 먼지 등을 제거하기 위해 사용되는 필터의 실직적인 교환주기를 풍량센서 또는 광원을 이용하여 정확히 측정하여 알려주도록 함으로써 제때에 필터를 청소하거나 교환할 수 있도록 한 것이다.The present invention relates to a method for measuring the filter replacement cycle of an air purifier, and in particular, the actual replacement cycle of a filter used to remove fine dust, total suspended bacteria, dust, etc. of an air purifier (or total heat exchanger, ventilation device, etc.) By using the air volume sensor or light source to accurately measure and inform the filter, it is possible to clean or replace the filter in time.

최근, 봄철 등에 미세먼지가 많이 발생하여 대기오염도가 악화되면 숨쉬기 어려운 대기상태가 되며, 이러한 미세먼지를 그대로 여과없이 들이마실 경우 폐가 손상되거나 최악의 경우에는 폐렴에 걸리게 되는 등의 건강상 위험한 지경에 이르게 되는 경우가 있다.Recently, a lot of fine dust is generated in spring, etc., and when the air pollution level deteriorates, it becomes a difficult atmosphere to breathe. There are times when it comes to

종래에는 상기와 같은 미세먼지를 제거하기 위한 수단으로, 공기청정기나 전열교환기 등을 많이 사용하고 있다.Conventionally, as a means for removing the fine dust as described above, an air purifier or a total heat exchanger is widely used.

일반적으로 공기청정기는 공기에 포함되어 있는 오염물질을 정화하여 신선한 공기로 바꾸는 장치로 외부의 공기를 공기청정기 내로 유입시켜 이에 포함된 오염물질을 정화한 후 정화된 공기를 외부로 토출한다.In general, an air purifier is a device that purifies contaminants contained in air and replaces it with fresh air. The air purifier flows into the air purifier, purifies the contaminants contained therein, and then discharges the purified air to the outside.

이를 위하여 공기청정기는 공기내의 오염물질을 걸러내기 위한 필터를 구비하는데, 공기청정기의 필터는 사용시간이 경과함에 따라 공기정화 능력이 떨어지므로 주기적으로 필터를 교환할 필요가 있다.To this end, the air purifier includes a filter for filtering out contaminants in the air. The filter of the air purifier loses its ability to purify the air over time, so it is necessary to periodically replace the filter.

종래에는 대표적인 공기청정기 사용환경 및 사용시간을 기준으로 각 필터별 수명을 미리 설정하고 이에 따라 필터를 주기적으로 교환하였으나, 공기청정기의 실제 사용환경 및 사용시간에 따라 필터의 수명이 변경될 수 있으므로 적절한 시기에 필터를 교환하기에는 한계가 있었다In the prior art, the lifespan of each filter was set in advance based on the typical air purifier usage environment and usage time, and the filters were periodically exchanged accordingly. There was a limit to replacing the filter in time

즉, 종래 공기청정기나 전열교환기의 내부에는 미세먼지를 제거하기 위한 필터를 내장하여 사용하고 있는데, 장시간 환기를 하거나 기기를 동작시키면 필터의 성능이 떨어지거나 망가져서 필터를 교환해야 한다.That is, the conventional air purifier or total heat exchanger has a built-in filter for removing fine dust, but if the device is ventilated for a long time or the device is operated, the performance of the filter is deteriorated or damaged, and the filter must be replaced.

상기와 같이 필터를 교환할 때, 종래에는 별도의 필터 교환주기 알림수단이 제시되어 있지 않으므로 사용자가 주기적으로 일일이 확인을 하거나 기기에서 알람을 울리게 하는 방법에 의해 필터를 점검하였다.When replacing the filter as described above, conventionally, a separate filter replacement cycle notification means is not provided, so the user periodically checks the filter one by one or checks the filter by a method of sounding an alarm in the device.

그러나 상기와 같이 주기적으로 필터의 교환시기를 사용자가 확인해야 하는 경우에는 부주의로 점검일자를 잊어버리기 쉽고, 기기에서 알람을 울리게 하는 경우에는 필터의 상태와 상관없이 일정시간 지나면 필터교환 알람을 하게 되므로 아직 사용가능한 제대로 된 필터이지만 그대로 교환하여 낭비하게 되는 결점이 있으며, 이미 기능이 떨어진 상태의 필터에 있어서 교환을 위해 뒤늦게 알람을 하는 경우에는 기능이 떨어진 필터를 그대로 사용했던 결점이 있었다.However, if the user needs to periodically check the filter replacement time as described above, it is easy to forget the inspection date inadvertently. Although it is a good filter that can still be used, it has the drawback of wasting it by replacing it as it is, and in the case of a belated alarm for replacement in a filter that has already lost its function, there is a drawback of using the filter with the reduced function as it is.

본 발명은 상기와 같은 종래의 결점을 해결하기 위한 것으로, 본 발명의 목적은, 필터를 사용하게 되면 일정크기의 먼지나 물질들이 필터에 의해 걸러져서 깨끗한 공기로 필터링되어 배출되는데 이러한 필터의 후방에 풍량센서를 설치하여 필터가 초기 깨끗한 상태에서의 풍량데이타값과 사용후 필터가 더러워진 상태에서의 풍량데이타값의 차이를 서로 비교하여 측정된 풍량데이타값이 기준 설정 데이타값보다 크면 필터의 교환시기로 인식하여 이를 사용자에게 알려주도록 하는 공기청정기의 필터 교환주기 측정방법을 제공하는데 있다.The present invention is to solve the conventional drawbacks as described above, and an object of the present invention is that, when a filter is used, dust or substances of a certain size are filtered by the filter and filtered into clean air. By installing an airflow sensor, the difference between the airflow data value when the filter is initially clean and the airflow data value when the filter is dirty after use is compared with each other. An object of the present invention is to provide a method for measuring the filter replacement cycle of an air purifier that recognizes and informs the user.

본 발명의 다른 목적은, 필터의 전방에서 광원을 조사하게 하고 필터의 후방에서는 광원감지기를 설치하여 필터의 막힘정도에 따른 측정 데이타값과 초기 설정데이타값을 비교 측정함으로써 필터의 상태를 측정 및 표시하도록 하는 공기청정기의 필터 교환주기 측정방법을 제공하는데 있다.Another object of the present invention is to irradiate the light source from the front of the filter and install a light source detector at the rear of the filter to compare and measure the measured data value according to the degree of clogging of the filter and the initial set data value to measure and display the filter status. An object of the present invention is to provide a method for measuring the filter replacement cycle of an air purifier.

이와 같은 목적을 달성하기 위한 본 발명은, 풍량센서를 이용한 필터주기 측정방법으로, 필터와 모터사이에 풍량센서를 설치하고, 상기 풍량센서는 콘트롤보드에 의해 제어되도록 구성하여 상기 콘트롤보드에 필터의 초기데이타값을 설정한 상태에서 필터 사용중 더러워진 정도를 측정 및 초기 설정값과 비교하여 측정데이타값이 기준설정 데이타값보다 크면 필터교환시기로 인식하여 이를 자동적으로 표시하여 줌과 함께 경보를 발하도록 구성함을 특징으로 한다.The present invention for achieving the above object is a filter period measuring method using an air volume sensor, installing an air volume sensor between the filter and a motor, and the air volume sensor is configured to be controlled by a control board. When the initial data value is set, the degree of dirtiness while using the filter is measured and compared with the initial set value. It is characterized by

본 발명은 필터 전방에 엘이디램프를 설치하고 필터 후방에는 광원센서를 구비함과 함께 상기 광원센서는 콘트롤보드에 의해 제어되도록 구성하여 상기 콘트롤보드에 엘이디 램프가 필터를 조사하는 초기데이타값을 설정한 상태에서 필터 사용중 측정데이타값과 초기데이타값을 비교하여 측정데이타값과 초기데이타값보다 크면 필터의 교환시기로 인식하여 이를 자동적으로 표시하여 주거나 경보를 발하도록 구성함을 특징으로 한다. In the present invention, an LED lamp is installed in front of the filter and a light source sensor is provided behind the filter, and the light source sensor is configured to be controlled by a control board. It is characterized in that by comparing the measured data value and the initial data value while the filter is in use in the state of being used, if the measured data value and the initial data value are larger than the measured data value and the initial data value, it is recognized as the replacement time of the filter and automatically displayed or an alarm is generated.

이상에서 상세히 설명한 바와 같이 기존에는 공기청정기의 사용시 필터의 교환시기를 알려 줄 수 있는 별도의 수단이 없어 사용자가 필터의 교환시기를 용이하게 판단하기 어려웠으나 본 발명에서는 필터의 후방에 풍량센서를 설치하여 필터가 초기 깨끗한 상태에서의 풍량데이타값과 공기청정기 사용중 필터가 더러워진 상태에서의 풍량데이타값의 차이를 비교 측정하여 측정데이타값이 기준설정데이타값보다 크면 필터의 교환주기로 인식하여 이를 표시수단을 통해 알려줄 수 있는 효과가 있다.As described in detail above, it is difficult for the user to easily determine when to replace the filter because there is no separate means for notifying the replacement time of the filter when using the air purifier. Thus, the difference between the air flow data value when the filter is initially clean and the air flow data value when the filter is dirty while the air purifier is in use is compared and measured. It has the effect of letting you know.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.The operation of the present invention configured in this way will be described as follows.

도 1은 본 발명의 풍량센서를 사용한 공기청정기의 필터 교환주기 측정방법을 설명하기 위한 것으로, 필터(1)의 후방에 풍량센서(3)를 설치하고 상기 풍량센서(3)는 케이블을 통해 메인 콘트롤보드(4)에 전기적으로 연결시킨다.1 is to explain a method for measuring a filter replacement cycle of an air purifier using the air volume sensor of the present invention, and the air volume sensor 3 is installed at the rear of the filter 1, and the air volume sensor 3 is connected to the main through a cable.

상기 메인 콘트롤보드(4)는 메모리부(4a)와 제어부(4b)로 이루어진다.The main control board 4 includes a memory unit 4a and a control unit 4b.

필터(1)가 초기에는 깨끗한 상태이므로 풍량센서(3)에서는 풍량이 양호하게 불어오는 것을 인식하게 되며, 이때 풍량센서(3)에 의해 측정된 측정데이타값은 콘트롤보드(4)의 메모리부(4a)에 저장되며 이러한 풍량 데이타 값이 설정기준데이타값이 된다. Since the filter 1 is initially clean, the air volume sensor 3 recognizes that the air volume is blowing well, and the measured data value measured by the air volume sensor 3 is stored in the memory unit ( 4a) and this air volume data value becomes the set reference data value.

한편, 공기청정기를 장시간 사용하다 보면 필터(1)에 공기중의 먼지 등이 쌓이게 되는데, 이때 풍량센서(3)에서 필터(1)를 통과하는 풍량을 측정하여 이 측정데이타값을 콘트롤보드(4)로 보낸다.On the other hand, when the air purifier is used for a long time, dust in the air accumulates on the filter (1). ) to send

If the measured data value is larger than the initial data value compared with the value, the control unit 4b recognizes that it is time to replace the filter and automatically displays the replacement state or issues an alarm.

또한, 상기 콘트롤보드(4)가, 공기청정기의 운전 개시 시점에서 엘이디램프(5)로부터 비추는 빛이 필터(1)를 통해 광원센서(6)에 의해 감지되는 필터(1)의 초기설정데이타를 저장하고 필터(1)의 사용시 필터(1)의 막힘상태 측정 시점에서의 상기 광원센서(6)의 광원데이타값을 저장하는 메모리부(4a)와, 상기 필터(1)의 초기상태에서의 광원센서(6)의 광원데이타값과 나중에 필터(1) 사용시의 필터(1)의 막힘상태에서 측정된 광원센서(6)의 광원데이타값을 비교하여 막힘상태에서의 광원데이타값이 초기설정상태에서의 광원데이타값보다 크면 필터 교환시기로 판단하는 제어부(4b)를 포함한다.In addition, the control board 4 receives the initial setting data of the filter 1 in which the light emitted from the LED lamp 5 is detected by the light source sensor 6 through the filter 1 at the start of operation of the air purifier. A memory unit 4a for storing and storing the light source data value of the light source sensor 6 at the time of measuring the clogging state of the filter 1 when the filter 1 is used, and the light source in the initial state of the filter 1 By comparing the light source data value of the sensor 6 with the light source data value of the light source sensor 6 measured in the clogged state of the filter 1 when the filter 1 is used later, the light source data value in the clogged state is changed from the initial setting state. If greater than the light source data value of the control unit (4b) for determining the filter replacement time.

이와 같은 본 발명의 다른 실시예에 있어서는, 광원센서(6)를 사용한 공기청정기의 필터 교환주기 측정방법으로, 필터(1)의 전방에 엘이디램프(5)를 설치하고, 필터(1)의 후방에 광원센서(6)를 설치함과 함께 상기 광원센서(6)는 케이블을 통해 메인 콘트롤보드(4)에 전기적으로 연결시킨 것으로, 상기 메인 콘트롤보드(4)는 메모리부(4a)와 제어부(4b)로 이루어져 초기 엘이디램프(5)로부터 초기설정상태에서의 광원센서(6)의 광원데이타값과 나중 필터사용시의 필터(1)의 막힘상태에서 측정되는 광원센서(6)의 광원데이타값을 비교한다.In another embodiment of the present invention, the LED lamp 5 is installed in front of the filter 1 as a method of measuring the filter replacement cycle of the air purifier using the light source sensor 6 and the rear of the filter 1 is installed. The light source sensor 6 is electrically connected to the main control board 4 through a cable, and the main control board 4 has a memory unit 4a and a 4b) and the light source data value of the light source sensor 6 in the initial setting state from the initial LED lamp 5 and the light source data value of the light source sensor 6 measured in the clogged state of the filter 1 when the filter is used later.

따라서, 초기설정상태에서의 광원센서(6)의 데이타값과 막힘상태에서의 광원센서(6)의 데이타값의 차가 기설정된 기준데이타값보다 큰 경우 제어부(4b)에서는 필터교환시기임을 판단하게 된다.Accordingly, when the difference between the data value of the light source sensor 6 in the initial setting state and the data value of the light source sensor 6 in the clogged state is greater than the preset reference data value, the control unit 4b determines that it is time to replace the filter. .

즉, 필터(1)가 초기에는 깨끗한 상태이므로 이때 엘이디램프(5)에서 발하는 빛을 필터(1)를 통해 광원센서(6)에서 측정하여 이를 필터(1)의 초기데이타값으로 콘트롤보드(4)의 저장부(4a)에 저장해 놓으며, 이러한 광원초기데이타가 필터(1)교환시기의 설정기준 데이타값이 되는 것이다. That is, since the filter 1 is initially clean, the light emitted from the LED lamp 5 is measured by the light source sensor 6 through the filter 1, and this is used as the initial data value of the filter 1 on the control board 4 ) is stored in the storage unit 4a, and this light source initial data becomes the set reference data value of the filter (1) replacement time.

한편, 공기청정기를 장시간 사용하다 보면 필터(1)에 공기중의 먼지 등이 쌓이게 되는데, 이때 광원센서(6)에서 필터(1)를 통과하는 엘이디램프(5)의 빛의 정도를 측정하게 된다.On the other hand, when the air purifier is used for a long time, dust in the air accumulates on the filter 1, and at this time, the light source sensor 6 measures the light level of the LED lamp 5 passing through the filter 1 .

따라서, 필터(1)가 막힌 상태에서의 광원센서(6)의 측정데이타값이 콘트롤보드(4)로 입력되면, 콘트롤보드(4)의 제어부(4b)에서는 메모리부(4a)에 저장된 기설정된 기준데이타값과 광원센서(6)의 측정데이타값을 비교하여 측정데이타값이 기준데이타값보다 크면 필터(1)를 교환해야 할 때가 되었으므로 이를 판단하여 표시수단을 통해 알려주게 되는 것이다.Therefore, when the measured data value of the light source sensor 6 in the state in which the filter 1 is blocked is input to the control board 4, the control unit 4b of the control board 4 stores the preset value stored in the memory unit 4a. By comparing the reference data value and the measured data value of the light source sensor 6, if the measured data value is greater than the reference data value, it is time to replace the filter 1, so it is determined and informed through the display means.

본 발명은 상술한 바와 같이 풍량과 광원을 이용한 필터(1)의 교환주기 측정에 관한 실시예를 제시하였으나, 본 발명은 이에 국한되는 것은 아니며, 다양한 수단을 활용하여 필터의 교환주기를 측정하고 이를 알려줄 수 있음은 물론이다.As described above, the present invention has presented an embodiment regarding the measurement of the replacement period of the filter 1 using the air volume and the light source, but the present invention is not limited thereto. Of course you can tell.
